Glossary of terms

In this place, the following terms or expressions are used with the meaning indicated:

Bolt

means a sliding, pivoted, or otherwise movable member such as is normally carried by a door to hold it shut by engagement with a keeper on the frame. It may be operated by hand directly or through mechanism or by a key; it may be a latch (see below);

Frame

means any member to which a wing may be held by a fastening device. It does not include a framework forming part of the wing, but it may be another wing.

Hasp

means a member hinged to the frame or wing so that it can be moved towards the face of the wing or frame and secured thereto, e.g. by a turn-button, by a padlock and staple.

Latch

means a bolt arranged to be moved to the releasing position against the force of a spring, or some other returning force, when a wing meets the frame on closing, so that it does not have to be operated by hand to secure the wing, but only to open it.

Lock

means primarily a device for releasing or securing any member, which requires a key or a permutation mechanism for release. In groups E05B 1/00- E05B 9/00, E05B 13/00- E05B 17/00, E05B 39/00- E05B 47/00, E05B 51/00, E05B 53/00, E05B 63/00 and E05B 65/00 however, the term "lock" may include other fastening devices.

Wing

is a general term for swingable, slidable, or otherwise movable doors or windows. This term also includes other movable structures such as drawers, lids of chests, car boots, or car bonnets, to which the operating, mounting, latching, or locking means covered by this class may be applied.

Glossary of terms

In this place, the following terms or expressions are used with the meaning indicated:

latching/unlatching

holding/release of a bolt element that a wing or door can be opened. A typical vehicle lock is unlatched when a detent, pawl or ratchet releases the fork shaped bolt

locking/unlocking

preventing/allowing an unlatching action. In the locked state an unlatching action, normally done by actuating a handle or grip, is prevented. A locked door or wing is at least prevented from being unlatched from outside of the vehicle

for accident situations
Definition statement

This place covers:

Locks designed to perform or prevent certain functions in case of accidents

Preventing unwanted lock actuation, e.g. unlatching, at the moment of collision
Definition statement

This place covers:

Locks, where an unwanted unlatching is prevented in case of an accident. One particular example is that a door handle could be accidentally actuated in case of a collision against the side door of a vehicle.

One way of preventing such an unwanted actuation is the provision of an extra long bowden cable. The extra length thereby prevents unwanted actuation, if a vehicle part is deformed.

The figure shows another construction, which should avoid actuation at the moment of a collision. Two parallel connecting rods (10, 11) are provided, such that if one of the rods (10,11) would be deformed during an accident, then it could not cause the lever (9) to turn since the second lever (11) would resist this by an equal force acting to turn the lever (9) in the opposite direction.

media11.png

by means of inertial forces
Definition statement

This place covers:

Means for preventing actuation caused by inertial forces acting on lock parts in case of an accident. Typically, a weight arrangement is used, which is actuated in order to block a handle against movement at the moment of collision.

The figure shows an example whereby at the moment of a collision a force (29b) would cause a mass-lever (30) to rotate counterclockwise. A blocking member (34) of the mass-lever (30) thereby prevents the handle (37) to be actuated by an inertial force (32b).

media12.png

Arrangements for protection of pedestrians
Definition statement

This place covers:

Locks designed for pedestrian protection. In practice, it almost always concerns engine compartment locks (E05B 83/24)

The example in the figure concerns an active front hood system, whereby both the hinge part (41) and the lock (25) are designed such that they are automatically raising the hood (13) in case of a collision with a pedestrian. This allows the front zone of the vehicle to deform easier.

Allowing opening in case of deformed bodywork, e.g. by preventing deformation of lock parts
Definition statement

This place covers:

The general problem that a wing/door is frequently deformed at an accident. In this subgroup the lock is protected in such a way that it can be unlatched/unlocked even if the door is deformed. This is often achieved by protective plates, shields and reinforcements.

Another alternative is to design lock parts in order to be deformed in a controlled way, such that they can still function after an accident. In the figure the bolt (8) and the detent (13) are provided with deformation zones (17, 25, 26). In case of an accident the bolt and the detent will not break. They will rather be deformed plastically such that they will still function properly after the collision.

media14.png

Automatic locking or unlocking at the moment of collision
Definition statement

This place covers:

Arrangements whereby a particular action is forced to take place in case of an accident. The situation is more or less the opposite of E05B 77/04 in which a particular action is prevented.

A typical example is that a locking or an unlocking action is initiated at the accident. The choice of action depends on the security philosophy. Sometimes an unlocked door, which allows easy escape, is preferred and sometimes the preference is a locked door, which prevents (unwanted) opening of the door.

Another frequent example from this class is locks which after an accident remain locked for a certain time and then automatically move to an unlocked condition.

The example of the figure shows a system whereby a sensing means (50) is designed to pivot in case of an accident. This releases the bolt element (26) which is moved by a spring (52) into a striker (56). The door is therefore automatically locked at the moment of an accident.

Specially controlled locking actions in case of open doors or in case of doors moved from an open to a closed position, e.g. lock-out prevention or self-cancelling
Definition statement

This place covers:

Locks which usually concern the problem that vehicle keys can be left inside the vehicle, if the door would be accidentally closed in a locked condition.

Preventing locking with the bolt in the unlatched position, i.e. when the door is open
Definition statement

This place covers:

Locks in which the bolt position is sensed e.g. mechanically, magnetically or electrically. An unlatched bolt should thereby indicate an open door, and in this situation the locking system is blocked in order to make it possible to lock the door only after it has been closed.

The example of the figure illustrates this by a detent (20) having a cam (46) and a locking lever (24) having a shoulder (48).

When the bolt (14) is in its open position, the locking lever (24) cannot move to the locked position, since the shoulder (48) of the locking lever (24) is blocked by the cam (46) on the detent.

media16.png

Keyless locking with self-cancellation, e.g. resulting in an unlocking action when the door is being closed
Definition statement

This place covers:

Locks where the closing of the door always results in an unlocking action. The lock will thus never be in a locked state after having closed the door. This means that the door can always be unlatched after closing.

Override of self-cancellation, e.g. by actuation of the handle while the door is being closed
Definition statement

This place covers:

Arrangements whereby the automatic unlocking action can be prevented by overriding means, which require an additional action by the user, e.g. that the door handle is actuated during the closing of the door.

The user can thus decide, that the door should remain locked after closing, but this choice requires that a certain action is carried out during the closing. This makes it less likely, that the door is by mistake closed in a locked state.

According to the exemplifying figures, a lever (60) is actuated by a handle and can be used for unlatching the lock, if a release lever (64) can hit a pin (42) on the detent.

A locking lever (66) can move the release lever (64) to a locked position in which it will not hit the pin (42) as shown in the lower figure. A cam element (92a, 92b) rotates together with the actual latch bolt.

If the lock is brought to the locked position when the door and thereby also the bolt are in the open position, then the closing of the door will rotate the bolt to the latched position. The cam (92b) will therefore act on an intermediate element (94), which brings the locking lever (66) back to the unlocked position.

If however the handle lever (60) is actuated during the closing of the door, then the cam (92b) will not be able to contact the intermediate3 element (94) as shown in the right-hand figure. The lock will thereby stay in the locked position.

preventing use of an inner door handle, sill button, lock knob or the like
Definition statement

This place covers:

Essentially the subjects "child safety" and "super-locking/double-locking". Even though the general purpose of preventing an inside handle from being used is the same for these both functions, there is one fundamental difference.

Child safety prevents the use of an inside handle at any time, i.e. the inside handle can never be used regardless if the door is unlocked or locked from the outside. A double-locked/super-locked door has an inside handle, which cannot be used, when the door is locked from the outside.

specially adapted for child safety
Definition statement

This place covers:

Locks which prevent all use of an inside handle, when the child safety is activated. This means that the inside handle cannot be used regardless if the door is unlocked or locked from the outside.

The figure shows a child safety arrangement with an actuation button (7) of the push-push type. Every time the button (7) is pushed, the system changes between an active and an inactive state.

media18.png

for anti-theft purposes, e.g. double-locking or super-locking
Definition statement

This place covers:

Locks having an inside handle, which cannot be used, when the door is locked from the outside. It is therefore not possible to open the door by breaking a window in order to reach the inside handle.

The double-locking can be achieved either by uncoupling or blocking of the inside lock system and inside handle.

In the figure, an example of a blocking system is shown. A double-lock arrangement (9, 12) prevents any actuation of an inside lock knob rod (7).

media19.png

allowing opening by means of an inner door handle, even if the door is locked
Definition statement

This place covers:

A combined unlocking and unlatching function of the inside door handle. This is sometimes achieved by one single actuation of the handle. Another possibility is that a first actuation of the handle unlocks the door and that the second actuation unlatches the door.

The figure shows an example of an inside handle (7), which can be moved from a neutral position (A) to an unlatching position (B). If the door would be locked, then the same handle can be moved from the neutral position (A) to an intermediate position (C) and back to the neutral position (A) in order to unlock the lock. The handle can thereafter be actuated one more time to position (C) for unlatching.

media20.png

allowing simultaneous actuation of locking or unlocking elements and a handle, e.g. preventing interference between an unlocking and an unlatching action
Definition statement

This place covers:

Arrangements addressing the well known problem that an unlocking (or locking) action can fail, if the handle of the door is actuated at the same time.

Often a second unlocking action is required. This problem is normally avoided by an energy accumulation arrangement of springs.

Protection against weather or dirt, e.g. against water ingress (closures or guards for keyholes E05B 17/14)
Definition statement

This place covers:

Means offering protection against weather influence. This can for example be achieved by a totally closed lock housing or by arranging some parts of the lock in a "wet compartment" and other parts in a "dry compartment". Another type of weather protection concerns means preventing freezing of the lock in cold conditions.

In the figure, a "wet area" (N) of the lock comprises the main lock elements, i.e. the bolt (3a) and the detent (3b). A sensing arrangement (7a, 7b) for determination of the detent position is housed in a "dry area" (T) o the lock. A single thin link rod (50) extends from the "wet area" to the "dry area" through a small opening (80).

Definition statement

This place covers:

Ways of reducing noise and vibrations in locks. The example in the figure shows a lever element (8) of a lock. The end positions of the lever are defined by stretching of cord elements (3, 3a). The use of cords for this purpose reduces the noise of the lever (8) reaching its end position.

Cushion elements, elastic guiding elements or holding elements, e.g. for cushioning or damping the impact of the bolt against the striker during closing of the wing
Definition statement

This place covers:

Elastic blocks, elastic guiding elements etc. which are typically placed in the zone of engagement between the bolt and the striker. One function of such blocks can thus be to make an impact between moving elements softer.

Another purpose can be to hold for example a striker firmly fixed in the latched position. This prevents noise due to rattling.

In the figure, an elastic cushion means (30, 40) defines a seat for firmly holding the striker (2).

Lock elements covered by silencing layers, e.g. coatings
Definition statement

This place covers:

Bolts, strikers, detents etc. which are covered by a (thin) anti-noise coating/layer. One rather typical example is a metal bolt with a plastic coating.

According to the exemplifying figure, a coating (16) of elastically deformable material allows any direct contact between the base plate (2) of the striker and the bodywork of the vehicle. The noise produced during closing of the lock is thereby reduced.

Means for damping the movement of lock parts, e.g. slowing down the return movement of a handle (E05B 77/38 takes precedence)
Definition statement

This place covers:

Arrangements for damping of movements. This class does however not cover elastic blocks/guides (E05B 77/38). It is rather directed to dampers, for example of the fluid type. A typical example is a damper, which slows down the return movement of a handle.

The return movement of the handle in the figure is slowed down by a fluid damper (30).

Actuators driven by electricity. The figure shows a lock with a handle (3), which can release a bolt (2) from a striker (6). The bolt (2) can also be released by electrically heating a shape memory alloy actuator wire (9). This heating shrinks the actuator wire, and the bolt (2) will consequently be released from the striker (6).

Definition statement

This place covers:

Various ways of using an actuator in a vehicle lock. These uses are thereby in principal defined depending on which lock part(s) the actuator is connected to.

operating on bolt detents, e.g. for unlatching the bolt
Definition statement

This place covers:

A typical vehicle lock comprises a fork-shaped rotary latch bolt, which is kept in its latched position by a detent. In this subgroup the power actuator releases the detent of the bolt and consequently an unlatching takes place. The result of the powered actuation is thus that the door is free to be opened.

The figure shows an actuator (12), which drives cam elements (17) through a geared transmission. The cam elements (17) act on a detent (2) in order to unlatch the bolt (1).

media44.png

operating on locking elements for locking or unlocking action
Definition statement

This place covers:

Actuators which achieve the movement of a locking element (typically a locking lever) between a locked and an unlocked position.

The actuator consequently moves the lock between an unlocked state wherein the bolt is allowed to move and a locked state in which the movement of the bolt is prevented.

The movement of the bolt is thus not directly influenced by the actuator. A very common example in this subgroup is the powered locking/unlocking of central-locking arrangements.

According to the figure, a locking lever (10) is pivotally mounted on the output axis (12) of an actuator (14). The locking lever (10) can be moved between a locked and an unlocked position by means of the actuator (14).

media45.png

Definition statement

This place covers:

Actuator acting on the bolt in order to move it, normally from a position in which it holds the door closed to a position in which the door can be opened, or vice-versa. It could thereby concern both latch bolts and dead bolts.

Definition statement

This place covers:

Pulling the door tight or pushing the door slightly open. It is to be noted, that this subgroup covers the cases where these (small) movements of the door are achieved by the lock. This should not be confused with the powered closing /opening of for example E05F 15/00, where the wing is moved from a (more or less) open position to a (more or less) closed position.

The example illustrates this by an actuator (21), which uses a pushing element (22) in order to assist movement of a bolt from a half-latched to a fully-latched position.

media47.png

by movement of the striker
Definition statement

This place covers:

A movable striker for achieving the final closing or the initiated opening. A typical example is that after a first engagement between a striker and a bolt, the striker is moved by an actuator in order to further pull the wing tight.

The exemplifying figure shows an actuator in the form of an electric motor (8). When an axis (9) is turned by the motor (8), a pin (6) moves in an inclined slot (5) of a striker base (2). The actual striker (3) can thereby be driven by the motor (8) for assisting the movement of the door to a fully closed position.

Actuators being driven in a single direction
Definition statement

This place covers:

Actuators moving only in one direction. From a starting position, the actuator moves continuously in one step or in several steps, always in the same direction, until it arrives back at the starting position again.

One example can be seen in the figure, where the motor (2) and the actuating element (8) can only turn in one direction (3,9). An electric arrangement (17) is provided for minimizing the back-drive when the drive pin (10) hits an abutment stop (12). When the detent pawl (11) has moved further clock-wise, then the actuator can continue to move in its single driving direction (3,9).

It is to be noted, that essentially the whole movement cycle should be power actuated. If for example a significant part of the movement is achieved by e.g. a mechanical spring, then the subgroup E05B 81/50 takes precedence.

Powered actuators with automatic return to the neutral position by non-powered means, e.g. by springs
Definition statement

This place covers:

Actuators which are power driven to move from a neutral position to an active position, and the return movement to the neutral position is provided by non-powered means.

Examples of such arrangements can for example be a linearly moving solenoid, whereby an output member is moved electro-magnetically from a neutral position to an active position. When the power later is cut, a spring is arranged for moving the output member.

In the figure a geared transmission is moved by powered means to an active position. At the same time a geared rack (130) is moved, and this compresses spring (146). When the power is cut, the accumulated energy of the compressed spring (146) moves the rack (130) in the opposite direction such that the actuator returns to its normal position.

Handles with some kind of electrical function. It first of all concerns handles working more or less as an electrical switch. The handle does thus not perform any mechanical action on the lock. It is simply a switch for sending a signal (e.g. by closing a circuit) to the lock-electronics.

This subgroup also covers handles, which perform both a mechanical function as well as an electric function.

An example of a switch- type handle is given in the figure. This shows an opening switch for vehicle doors or trunks, which is actuated by pressing the cover element (3) in the direction of the arrow.

as part of a hands-free locking or unlocking operation
Definition statement

This place covers:

Handles used for the initiation of a hands-free opening. A sensor or switch in or near the handle starts the data transfer. This could be done either by moving the handle in a predetermined way or by a proximity sensor, which registers the approach of a hand towards the handle.

It should be noted that this class does not concern the details of the coded data transmission between the lock and a transponder key.

According to the example in the figure, two switches (28,29) can be sensed/actuated by different actions of a user´s hand for example in order initiate a hands-free opening process.

characterised by the power supply; Emergency power operation
Definition statement

This place covers:

Various kinds of energy sources (other than the vehicle main battery) and spare-power devices.

If the main power source is defect (for example because the main battery of the vehicle is empty), then these power sources can provide a small amount of power for an emergency opening of the vehicle. This section also covers cases where the primary energy source is not the vehicle main battery. This would for example sometimes be the case for certain types of battery charged locks.

using batteries other than the vehicle main battery
Definition statement

This place covers:

Additional batteries or back up batteries used for example in case of failure of energy supply from vehicle main battery.

using manually operated generator means
Definition statement

This place covers:

Generators operated by the vehicle user. Such generators can be adapted for supply of energy for example by handle movement, opening/closing of the door or introduction of the key into the keyhole. The figure shows a generator (22), which supplies energy for the operation of the actuator (17) when the voltage of the main battery is below a certain level.

media72.png

using capacitors
Definition statement

This place covers:

The use of capacitors for provision of energy for example when the main battery has been discharged. The figure shows a number of supercapacitors (30) which are available as a back-up energy source. A diode (32) or similar component prevents discharge of the supercapacitors (30) into the main power supply means.

media73.png

using inductive energy transmission
Definition statement

This place covers:

The use of induction for provision of energy. This can be used in situations when it is desired to avoid cables and contacts. One example of this type of arrangement is the provision of a coil in the key another coil in the lock for non-contact supply of emergency power to the lock.

Manual override in case of power failure
Definition statement

This place covers:

Purely mechanical manual override means. One example would be a door handle, which in normal use electrically activates an actuator. In case of a power failure this handle can be actuated further or in another direction in order to actuate the lock mechanically.

This subgroup also covers cylinder locks in normally not visible, concealed positions. In the figure, a cylinder lock (9) is for example mounted behind the rear-view mirror (1).

It is to be noted, that this subgroup does not cover normally visible, non concealed cylinder locks mounted in or near the door handle.
