Definitions
- the invention relates to a lock, comprising a lock part for mounting in or on a door, in which a bolt provided with a bevelled side is slidably mounted, and a staple part or a closing plate for mounting against a door jamb provided with an opening into which the bolt drops when the door is closed.
- Locks of this type are generally known. They are for instance applied in substantially any front door in order to achieve that the front door locks automatically when it is pulled shut.
- the bevelled side here comes into contact with an edge of the staple part or the closing plate, and the bolt is pressed inward counter to the action of a spring up to the moment at which the bolt can drop into the opening.
- the drawback of the known lock is that a plate-like object can be pushed between the door jamb and the door such that an edge of this plate-like object comes to rest against the bevelled side of the bolt. If the plate-like object is now pushed further inward the bolt then slides into the lock part counter to the action of the spring, and the door can be opened.
- the lock according to the invention obviates this drawback in that the bevelled side of the bolt takes a relatively obtuse form such that the bevelled side is positioned at least substantially wholly inside the staple part or the closing plate when the door is closed. In this way it is easily possible to prevent the bolt being pressed into the lock part by a plate-like object during 'shimmying' because the force exerted by the plate-like object is perpendicular of a possible direction of movement of the bolt.
- the short side is provided with a groove running at least substantially perpendicularly of a direction of movement of the bolt over a full width of the bolt.
- a plate-like object which is pressed against the side of the bolt during shimmying will then come to lie in the groove, whereby it is practically impossible to exert a laterally directed force on the bolt.
- a lock according to the preamble of claim 1 is known in the field.
- the lock according to the invention it is important to mount the staple part or the closing plate such that an edge of the staple part or the closing plate only just comes into contact with the bevelled side and that the bevelled side can still disappear almost completely into the staple part.
- the lock according to the invention achieves this owing to the characterizing measure that a transition from a short side of the bolt to the bevelled side is provided with a first rounding which in a situation of use comes into contact with the edge of the staple part or the closing plate, whereby mounting can be significantly simplified.
- the groove moreover has in a transverse direction a concave, at least substantially half-round profile so that the edge comes to lie at the bottom, practically in the centre of the groove, whereby it is impossible to exert a laterally directed force on the bolt using the plate-like object.
- the concave profile results in a relatively shallow groove being sufficient, whereby notch effect is prevented and the bolt retains its strength.
- an edge of the groove positioned close to the bevelled side is provided with a second rounding which is a continuation of the first rounding, so that the first rounding and the second rounding together form a non-sharp rib via which an edge of the plate-like object is guided to the groove.
- the non-sharp rib ensures a good closure.
- the groove has a substantially semicircular shape in a transverse direction.
- the rib has a substantially semicircular shape.
- the bevelled side has a substantially partially circular shape.
- a semicircular and partially circular shape is understood to mean respectively a shape of a semicircle and a part of a circle which can be defined by means of a radius. The circular shapes follow a smooth progression and make possible a compact bolt which is burglar-proof and also closes properly.
- a width of the groove preferably corresponds at least substantially to a distance between the lock part and the staple part or the closing plate, so that an edge of the plate-like object inevitably comes to lie at the bottom of the groove.
- the invention also relates to a bolt as described as part of a lock according to the invention.
- Fig. 1 is a cross-sectional view of a prior art lock, consisting of a lock part 1 which can be mounted on a door 2 and a staple-like part 3 which can be mounted on a door jamb 4.
- Lock part 1 comprises a bolt 5 which drops into an opening 6 of staple-like part 3 when the door is pulled shut, after which the door is closed and locked.
- a handle 7 is provided with which bolt 5 can be pulled out of opening 6 via a pull rod 8 counter to the action of a spring 9.
- the free stroke of bolt 5 is limited here by a rib 10 which is pressed into a cover 11 of lock part 1.

- bolt 5 is provided with a bevelled side 12 which makes contact with staple-like part 3 during closing and which is pressed into lock part 1 by staple-like part 3 counter to the action of spring 9. It is this bevelled side 12 which also makes it possible for the lock to be opened relatively easily from the outside by a burglar. It is sufficient here to slide in a flexible plate-like object 13, for instance a credit card, via a gap between door 2 and door jamb 4 until plate-like object 13 rests against bevelled side 12 of bolt 5.

Abstract
The invention relates to a lock, comprising a lock part for mounting against or in a door, in which a bolt provided with a bevelled side is slidably mounted, and a staple part or closing plate for mounting against a door jamb provided with an opening into which the bolt drops when a door is closed. In order to prevent the lock being opened using a flexible 'shim' by pressing this shim between the door and the door jamb, a bevelled side of the bolt is shortened such that this bevelled side drops wholly inside the staple part or the closing plate in the closed position. In order to make this method of opening the door completely impossible the bolt is moreover provided with a groove which runs perpendicularly of a direction of movement of the bolt and in which an edge of the flexible shim comes to lie.
Description
- The invention relates to a lock, comprising a lock part for mounting in or on a door, in which a bolt provided with a bevelled side is slidably mounted, and a staple part or a closing plate for mounting against a door jamb provided with an opening into which the bolt drops when the door is closed.
- Locks of this type are generally known. They are for instance applied in substantially any front door in order to achieve that the front door locks automatically when it is pulled shut. The bevelled side here comes into contact with an edge of the staple part or the closing plate, and the bolt is pressed inward counter to the action of a spring up to the moment at which the bolt can drop into the opening. The drawback of the known lock is that a plate-like object can be pushed between the door jamb and the door such that an edge of this plate-like object comes to rest against the bevelled side of the bolt. If the plate-like object is now pushed further inward the bolt then slides into the lock part counter to the action of the spring, and the door can be opened.
- The lock according to the invention obviates this drawback in that the bevelled side of the bolt takes a relatively obtuse form such that the bevelled side is positioned at least substantially wholly inside the staple part or the closing plate when the door is closed. In this way it is easily possible to prevent the bolt being pressed into the lock part by a plate-like object during 'shimmying' because the force exerted by the plate-like object is perpendicular of a possible direction of movement of the bolt.
- In the lock according to the invention the short side is provided with a groove running at least substantially perpendicularly of a direction of movement of the bolt over a full width of the bolt. A plate-like object which is pressed against the side of the bolt during shimmying will then come to lie in the groove, whereby it is practically impossible to exert a laterally directed force on the bolt.
- A lock according to the preamble of
claim 1 is known in the field. During mounting of the lock according to the invention it is important to mount the staple part or the closing plate such that an edge of the staple part or the closing plate only just comes into contact with the bevelled side and that the bevelled side can still disappear almost completely into the staple part. The lock according to the invention achieves this owing to the characterizing measure that a transition from a short side of the bolt to the bevelled side is provided with a first rounding which in a situation of use comes into contact with the edge of the staple part or the closing plate, whereby mounting can be significantly simplified. - According to a further characterizing measure the groove moreover has in a transverse direction a concave, at least substantially half-round profile so that the edge comes to lie at the bottom, practically in the centre of the groove, whereby it is impossible to exert a laterally directed force on the bolt using the plate-like object. The concave profile results in a relatively shallow groove being sufficient, whereby notch effect is prevented and the bolt retains its strength.
- According to a further characterizing measure, an edge of the groove positioned close to the bevelled side is provided with a second rounding which is a continuation of the first rounding, so that the first rounding and the second rounding together form a non-sharp rib via which an edge of the plate-like object is guided to the groove.
The non-sharp rib ensures a good closure. - According to a first preferred embodiment of the lock according to the invention, the groove has a substantially semicircular shape in a transverse direction. According to a further development of the first embodiment, the rib has a substantially semicircular shape. According to yet another development of the first embodiment, the bevelled side has a substantially partially circular shape. A semicircular and partially circular shape is understood to mean respectively a shape of a semicircle and a part of a circle which can be defined by means of a radius. The circular shapes follow a smooth progression and make possible a compact bolt which is burglar-proof and also closes properly.
- A width of the groove preferably corresponds at least substantially to a distance between the lock part and the staple part or the closing plate, so that an edge of the plate-like object inevitably comes to lie at the bottom of the groove.
- The invention also relates to a bolt as described as part of a lock according to the invention.
- The invention will now be further elucidated with reference to the following figures, in which:
- Fig. 1
- is a cross-sectional view of a prior art lock provided with a staple-like part;
- Fig. 2

Fig. 1 is a cross-sectional view of a prior art lock, consisting of alock part 1 which can be mounted on adoor 2 and a staple-like part 3 which can be mounted on adoor jamb 4.Lock part 1 comprises abolt 5 which drops into an opening 6 of staple-like part 3 when the door is pulled shut, after which the door is closed and locked. In order to open the door again from the inside ahandle 7 is provided with whichbolt 5 can be pulled out of opening 6 via apull rod 8 counter to the action of aspring 9. The free stroke ofbolt 5 is limited here by arib 10 which is pressed into acover 11 oflock part 1. Generally provided for the purpose of opening the door from the outside is a cylinder lock (not shown) via whichbolt 5 can also be pulled out of opening 6. In order to allowbolt 5 to drop smoothly into opening 6 during closing ofdoor 2,bolt 5 is provided with abevelled side 12 which makes contact with staple-like part 3 during closing and which is pressed intolock part 1 by staple-like part 3 counter to the action ofspring 9. It is thisbevelled side 12 which also makes it possible for the lock to be opened relatively easily from the outside by a burglar. It is sufficient here to slide in a flexible plate-like object 13, for instance a credit card, via a gap betweendoor 2 anddoor jamb 4 until plate-like object 13 rests againstbevelled side 12 ofbolt 5. By now pressing forcefully on plate-like object 13 thebolt 5 is pressed intolock part 1 counter to the action ofspring 9, and the door can be opened. -
Fig. 2 is a cross-sectional view of a possible embodiment of a lock according to the invention, likewise consisting of alock part 1 which can be mounted on adoor 2 and astaple part 3 which can be mounted on adoor jamb 4.Lock 1 comprises abolt 5 according to the invention, of which a relatively shortbevelled side 12 drops into opening 6 of staple-like part 3 when the door is pulled shut, after which the door is closed and locked. In order to open the door again from the inside ahandle 7 is provided with whichbolt 5 can be pulled out of opening 6 via apull rod 8 and counter to the action of aspring 9. The free stroke ofbolt 5 is limited here by arib 10 which is pressed into acover 11 oflock part 1. Generally provided for the purpose of opening the door from the outside is a cylinder lock (not shown) via whichbolt 5 can also be pulled out of opening 6. In order to allowbolt 5 to drop smoothly into opening 6 during closing ofdoor 2,bolt 5 is provided with afirst rounding 14 which makes contact withstaple part 3 during closing and which is pressed intolock part 1 bystaple part 3 counter to the action ofspring 9. Because bevelledside 12 drops wholly inside staple-like part 3 in a closed position, it is practically impossible to open the lock by sliding in a plate-like object 13 via a gap betweendoor 2 anddoor jamb 4. In order to make this method of opening the lock completelyimpossible bolt 5 is moreover provided with agroove 15 having a width at least corresponding to the width of the gap betweendoor 2 anddoor jamb 4. Plate-like object 13 then comes to lie at the bottom ofgroove 15, whereby it has become impossible to exert a force in the direction of movement ofbolt 5. In the case of an existing lock it is generally sufficient to replace the existing bolt with a bolt according to the invention, while the other components of the lock, such aspull rod 8,spring 9 andrib 10, can remain unchanged. The transition fromfirst rounding 14 togroove 15 is further preferably provided with asecond rounding 16, wherein first rounding 14 andsecond rounding 16 together form a non-sharp rib. - During closing of
door 2bolt 5 is pressed intolock part 1 using the relatively short, steepbevelled side 12. The intuitive expectation would be that this now requires more force and so will be more difficult. The opposite is found to be the case. Less force is necessary, and the forces occurring inlock part 1 are also smaller, whereby less wear occurs and the lifespan of the lock can be extended. -
Fig. 3 is a cross-sectional view of a further prior art lock, consisting of alock part 1 which can be mounted in adoor 2 using amounting plate 17 and which can co-act with aclosing plate 18 mounted ondoor jamb 4.Lock part 1 comprises abolt 5 which drops into anopening 6 ofmounting plate 17 when the door is pulled shut, after which the door is closed and locked. Provided for the purpose of opening the door again is for instance a doorhandle 19 or a cylinder lock (not further shown) with whichbolt 5 can be pulled out of anopening 21 in closingplate 18 via apull rod 8 and amechanism 20. In order to allowbolt 5 to drop smoothly into opening 21 during closing ofdoor 2,bolt 5 is provided with abevelled side 12 which makes contact with a slightly curved edge of closingplate 18 during closing, wherebybolt 5 is pressed intolock part 1. It is thisbevelled side 12 which also makes it possible for the lock to be opened relatively easily from the outside by a burglar. It is sufficient here to slide in a flexible plate-like object 13, for instance a credit card, via a gap betweendoor 2 anddoor jamb 4 until plate-like object 13 rests against bevelledside 12 ofbolt 5. By now pressing forcefully on plate-like object 13 thebolt 5 is pressed intolock 1 and the door can be opened. -
Fig. 4 is a cross-sectional view of a possible embodiment of a lock according to the invention, likewise consisting of alock part 1 which can be mounted in adoor 2 and aclosing plate 18 which can be mounted on adoor jamb 4.Lock 1 comprises abolt 5 according to the invention, of which a relatively shortbevelled side 12 drops into opening 21 of closingplate 18 when the door is pulled shut, after which the door is closed and locked. Provided for the purpose of opening the door again is for instance a doorhandle 19 or a cylinder lock (not further shown) with whichbolt 5 can be pulled out of anopening 21 in closingplate 18 via apull rod 8 and amechanism 20. In order to allowbolt 5 to drop smoothly into opening 21 during closing ofdoor 2,bolt 5 is provided with abevelled side 12 which makes contact with closingplate 18 during closing, wherebybolt 5 is pressed intolock part 1. In a closed position thisbevelled side 12 lies wholly inside opening 21 in closingplate 18. It is hereby practically impossible to open the lock by sliding in a plate-like object 13 via a gap betweendoor 2 anddoor jamb 4. In order to make this method of opening the lock completelyimpossible bolt 5 is moreover provided with agroove 15 having a width at least corresponding to the width of the gap betweendoor 2 anddoor jamb 4. Plate-like object 13 then comes to lie at the bottom ofgroove 15, whereby it has become impossible to exert a force in the direction of movement ofbolt 5. In the case of an existing lock it is generally sufficient to replace the existing bolt with a bolt according to the invention, while the other components of the lock, such asmechanism 20, can remain unchanged. The transition from first rounding 14 to groove 15 is further preferably provided with a second rounding 16, wherein first rounding 14 and second rounding 16 together form a non-sharp rib. -
Fig. 5A is a cross-sectional view of aprior art lock 1 together with aclosing plate 18 at themoment door 2 drops into the locked position.Bolt 5touches closing plate 18 here with its tip, whereby a couple also acts thereon in addition to an inward directed force, and this has an adverse effect on the friction and thereby on the wear oflock 1.Fig. 5B is a cross-sectional view of alock 1 according to the invention at themoment door 2 drops into a locked position.Bolt 5touches closing plate 18 here at a position far removed from the tip and at an advantageous angle, whereby the inward directed force is greater and the torque is smaller, whereby the bolt drops more easily into the lock and whereby the friction, and thereby the wear ofbolt 1, are moreover favourably affected.
