Definitions
- the invention relates to a catch for a lock, especially for catching a latch of a lock.
- the catch normally comprises a catch plate provided over an opening in a frame, such that the latch can enter into the opening in the frame through an opening in the catch plate.
- the opening in at least the catch plate has to be fit relatively tightly around the latch and has to be positioned relatively accurately relative to the frame in which the opening is made and to which the catch plate is mounted. This means that the mounting of the catch plate and providing the opening is time consuming and costly, and requires skill of the carpenter.
- the closing element When the closing element is deformed, for example bend, or displaced, or when for example a seal is ill fitting, the closing element may not fit entirely properly in the frame anymore. Such deformation can for example be the result of environmental issues, such as but not limited to humidity and/or dryness or humidity changes, improper support by its hinges, sagging or other defects of the closing element, its frame and/or its support.
- environmental issues such as but not limited to humidity and/or dryness or humidity changes, improper support by its hinges, sagging or other defects of the closing element, its frame and/or its support.
- the invention has as an aim to provide an alternative catch for the latch of a lock.
- An alternative aim of the invention is to provide for a solution to at least one of the problems sketched here above.
- a further alternative aim of the present invention is to provide an assembly for closing at least partly an opening in a frame by a closing element or to be used for such closure.
- a still further alternative aim of the invention is to provide a method for closing off an opening in a frame by a closure element.
- a catch for a lock latch can be defined by a cup for mounting in or on a frame, having a first side and an opposite second side.
- a biasing mechanism can be provided within the cup, comprising a displacement element which is biased in the direction of the second side by spring means.
- An opening shall be provided for inserting part of a latch of a lock which can engage the displacement element such that the displacement element will apply a force on the latch into the direction of the second side.
- a catch can be defined by a cup for mounting in or on a frame, having a first side and an opposite second side.
- a biasing mechanism can be provided within the cup, comprising a displacement element with a first part adjacent the first side and a second part extending nearer to the second side.
- a biasing element can be provided adjacent the second side for biasing the first part towards the second side, such that when a force is applied to the side of the first part facing the second side the first part is forced towards the first side and the displacement element will apply a counterforce on the first part.
- An assembly of a catch and a lock with a latch can be characterised by the latch fitting into the cup of the catch, between a first part of the displacement element and a second side of the cup, movable in a direction perpendicular to an insertion direction of the latch into the cup, between the first and second side of the cup.
- the latch preferably has an at least partly rounded off or tapering side near an end thereof forward in the insertion direction.
- a latch of a lock can be a translating type of latch, such as but not limited to latches commonly known as block latches, or pivoting latches. If there is more than one latch, the latches can be of individual locks or of a multiple point lock, centrally operated.
- a latch can be mechanically and/or electronically operated.
- insertion direction of a latch has to be understood as including but not limited to a linear movement direction and a pivoting movement direction, relative to the catch. At least in a pivoting movement such direction will be defined by an actual or virtual axis of pivoting of the latch. Also combined linear and pivoting movement can define such insertion direction.
- Another assembly according to the invention can be characterised by a catch according to the invention and a lock with a latch, mounted on a door or window or such closing element, hingedly connected to a frame to and/or into which frame the catch is mounted, wherein the closing element has a pivoting direction towards a closed position within the frame, and wherein the first side of the cup of the catch is positioned at an upstream side of the pivoting direction towards the closed position.
- a method for closing a closing element against a shoulder in a frame by at least a lock and a catch can be characterised by the catch catching a latch of the lock and forcing part of the closing element towards the shoulder by a displacement element biased towards the shoulder by a biasing element placed, when the closing element is in a closed position, at least partly between the latch and the shoulder.
- a door is shown as an example of a closing element, suspended in a frame, more specifically a doorframe, by hinges to one side and with three sets of cooperating latches and catches for closing the door on the opposite side.
- These latches can be part of three individual locks or of a centrally operated three point lock. Alternatively there can be only one lock latch or more than one, for example two or more than three.
- Any lock latch can be a single element such as but not limited to a latch having a substantially square cross section or a pivotable, hooking latch, or can have more than one element, for example a number of pins, extending for example parallel to each other, spaced apart as tines of a fork.
- Hinges and/or locks can be provided on different sides of the closing element. Similar locks and catches could be provided in different positions, for example between two doors or windows of a double door or window set, or between a door of window and the relevant frame, other than or additionally to the side opposite the hinges.
- the latch of a lock can be caught in a catch in and/or on a frame, such that for example misalignments of the latch and the catch relative to each other can be accommodated in at least one direction, especially in a direction substantially perpendicular to the opening area in the frame to be closed by the closing element.
- the frame has a first side, to or near which the closing element is suspended, and an opposite second side.
- the first side may be referred to as the outer side
- the opposite second side as the inner side, for example but not limited to when the closing element is a door or window at an outer side of a building, the closing element turning out for opening.
- the sides may be reversed.
- the catch can have a biasing element biasing an element of the catch in a direction towards the second side of the frame, i.e. in a closing direction of the closing element, such that when a latch of a lock connected to the closing element is caught in the catch, said latch and therewith the closing element may be pushed and/or pulled by the biasing element towards the closed position within the frame.
- the lock or locks with the latches are mounted on and/or in the closing element, the catches in and/or on the frame.
- this can be reversed entirely or in part, the or each lock or at least one thereof being in and/or on the frame and the or each catch or at least one thereof being in and/or on the closing element.
- the catch or catches has/have a longitudinal direction which extends, in mounted position into and/or on a frame, substantially vertically, unless otherwise specified. Obviously, the catches could also mounted differently.
- Fig. 1 shows a closing element 1, in this embodiment shown as a door 1 in a frame 2.
- the closing element 1 is mounted to the frame 2 by a number of hinges 3.
- the frame 2 can be provided, in a known manner, with a rabbet 4 providing an abutment 5 for the door 1, such that the door can close off the opening within the frame 2.
- a rabbet 4 providing an abutment 5 for the door 1, such that the door can close off the opening within the frame 2.

- a catch 6 can be provided for biasing a latch of a lock or the like in a direction of closure of a closing element 1.
- a catch 6 can be provided with a cup 7 for mounting in or on a frame 2, having a first side 8 and an opposite second side 9.
- Cup 7 has to be understood in the description as including at least but not limited to elements having partly open and/or partly closed frames with at least two opposite ends and a hollow or opening between said two opposite ends into which a latch can be entered at least partly.
- the frame has two relatively low side walls 18, substantially parallel, and two opposite end elements 19, connecting the walls 18, which end elements 19 are higher than the walls 18.
- a closed frame 20 is formed by the walls 18 and end elements 19, in this embodiment an integral frame 20.
- An opening 21 extends through the frame 20.
- the opening 21 can have a closed bottom 22, the opening 21 effectively being a hollow, or can be open to both sides.
- a biasing mechanism 10 can be provided within the cup 7.
- the biasing mechanism 10 can comprise a displacement element 11, which can be a lever or such type element, with a first part 12 adjacent the first side 8 and a second part 13 extending nearer to the second side 9 than the first part 12.

- the element 11 can for example be set or bend, forced or machined, from a suitable material such as metal or plastic.
- the element 11 has a length L which is larger than the widths W12, W13 of the first and second parts 12, 13, measured substantially perpendicular to said length.
- the angle between the two parts 12, 13 can for example be near 90 degrees, for example between 60 and 120 degrees, preferably between 75 and 105 and more preferably about 90 degrees, measured between lines extending through the connection 23 between the first and second part 12, 13 and the opposite sides 24, 25 thereof.

- Each support 26 is provided with a pivot element 27 which can be housed in corresponding openings 28 in each of the respective end elements 19, for defining a pivoting axis 29 for the element 11 relative to the cup 7.
- the axis 29 is positioned near the connection 23, which connection can be seen as the corner of the substantially L-shaped element 11.
- the first part can in some embodiments have a middle section 30 which is partly cut loose from the further part 13, and can be bent slightly towards the first side 8 of the cup 7.

- the element 11 when in an embodiment of fig. 2 - 5 the first part 12, or at least the free edge 37 thereof carrying possibly the element 31, is forced towards the first side 8, the element 11 will pivot around the axis 29, thus bringing the corners 33 of the second part 13 upward, i.e. towards the cover 36, when mounted, thus compressing the spring element 34, providing for or increasing a counter force on the second part 13 and thus the counter force FC, pushing against the force F.
- an element such as a latch of a lock, pushing against the first part 12 will be pushed toward the second side 9 by the element 11 due to the counterforce FC.
- the cover 36 is substantially U-shaped and dimensioned preferably such that it can be mounted over the frame 20, such that the two substantially parallel legs 37 of the cover extend between the elements 19 and abut the walls 18, whereas the wall part 38 of the cover 36, connecting the legs 37, extends between the upper sides of the elements 19, covering the opening 21.
- An opening 39 can be provided in the wall part 38, for allowing a latch 40 of a lock or the like to enter the catch 6 in the direction M. At least the element 31 or part of the first part 12 of the element 11 will be exposed below the opening 39, such that a latch 40 can engage the element 31 and/or the part 12 as such.
- the cover 36 can further be provided with mounting openings and/or elements for securing it to the cup 7 or frame 20 thereof.
- two openings 41 can be provided in the cover 36, for allowing bolts 42 to be screwed into nuts 43 provided below slot like openings 44 in the end elements 19.
- Covering elements 45 can be provided for covering the bolts 42, improving even further on the aesthetics
- the cup 7, especially the frame 20 can be provided with mounting openings 46, for example bores extending at an angle through the end elements 19, such that screws 49 can be screwed through said bores 46 into the frame 2, front 47 to back 48 of the cup 7, from nearer to the first side 8 to nearer or even past the second side 9, as is shown in fig. 5 .
- the cover 36 can cover the heads of the screws 49 used for mounting the cup 7 to the frame 2.
- a latch is shown, having a front end 50 entering the catch 6, especially the cup 7 in the direction I.
- the latch is conveniently provided with a slightly rounded side 51 at said end 50 facing the first side 8 of the catch 6.
- the end 50 of the latch 40 enters the cup 7 through the opening 39 in the cover 36.
- the end 50 of the latch 40 is moved against the element 31, or at least against the first part 12 of the element 11.
- the element 11 is biased by the springs 34 in or to a rest position, as shown in fig. 4A .
- the latch 40 is pushed towards the second side 9 of the cup by the element 11.
- the second part 13 is pushed back by the spring elements 14, tilting the element 11 back to its biased rest position, thereby applying the counter force FC on the latch 40.
- This will push the closing element 1 towards and preferably against the abutment of the frame 2.
- the movement of the latch and thus of the closing element may be limited by either the play in the direction towards the second side within the cup 7, for example limited by the opening 39, and/or by the play between the edge portion of the closing element and the adjacent abutment of the frame.
- the latch 40 shall be moved for example over a distance X corresponding to T1 - T2.
- a closing element can be pushed into a closing position by the catches 6, whereas this catch or these catches may provided for the possibility of correcting for for example misalignment between a lock or latch and a catch, which could exist or come into existence throughout the life time of the closing element, for example due to miscalculations, deformations of the closing element and/or frame or catch, wear of parts of the assembly of closing element, frame, lock or locks and catches, hinges and the like, or due to setting of for example the frame.
- These misalignments can also change in time, for example due to for example weather or use.
- Another advantage that can be obtained with a catch or several such catches 6 can be that when closing an element 1 a user does not have to push hard against the closing element, since the cooperating latch(es) and catch(es) will "push" the element into a closed position, if necessary.
- the opposite ends of the cup 7, especially of the frame 20 can be defined by the end elements 19, which can be rounded, preferably such that the radius of curvature of the elements 19 is about equal to the overall width of the frame 20, such that an opening or slot or the like for the catch can easily be made in a frame 2 by machining with a tool having the same curvature.
- the opening 39 preferably has a length L measured in a direction between the ends 19, which is such that a latch 40 can easily be inserted, and which substantially corresponds to the length L1 of the guiding element 31 on the element 11. By using such element 31 providing reduced friction the insertion of the latch in the direction I is improved.
- the opening 39 can extend into a leg 37 of the cover 36, at the first side 8 of the cup 7, for allowing the element 31 to move into the opening 39, providing extra space for pivoting of the element 11 without increasing the overall width Wo of the cup 7.
- the distance D between the side 60 of the frame 2 closest to the first side 8 and the side of the element 11 facing the latch 40 when inserted can be surprisingly small and/or the thickness T of the frame 2 remaining between said first side 8 and the side 60 of the frame 2 can be sufficiently great.
- a frame 2 can be used with a limited thickness between the abutment 5 and the side 60 of the frame 2, without compromising the strength of the frame or the mounting of the catch 6 therein.
- the angled screws 49 can also aid to this mounting strength, as discussed before.
- FIG. 6 and 7 an alternative embodiment of an assembly of a catch 6 and a latch 40 is shown, wherein the catch can be similar to or identical to the catch of fig. 2 - 5 , and wherein the latch 40 is a pivoting latch.
- the latch 40 is mounted on an axis 60 extending through the opening 61.
- a gear 62 can be provided, in fig. 6 shown in part as teeth 63 which can in a known manner be engaged by a rotating and/or translating part within the lock, which can for example be operated by a key, a lever mechanism, a motor or the like means, known in the art.
- a rotation of the latch 40 around said axis 60 in the direction indicated by arrow 64 will move a hooking part 65 of the latch 40 into and out of the cup 7, especially through the opening 39 in the cover 36, such that part of the hooking part 65 will hook behind the cover 36, especially behind the edge 66 of the opening 39 closest to a first of the end elements 19.
- the latch cannot leave the catch 6 in a linear direction, which can improve anti burglary properties.
- the opening 39 is preferably off set relative to a centre C of the catch, in longitudinal direction between both opposite end elements 19, such that such space 67 is mainly formed to one side of the opening 39.
- the hook part 65 can be tapering, chamfered, rounded or the like at a side facing the biasing element, such as the element 31 or the first part 12, in order facilitate such engagement further and reduce the force needed for inserting the hook part 65 of the latch when engaging the displacement element 11.
- the displacement element can have a direction of movement which encloses an angle with the direction of the force to be applied to the latch, which angle is preferably acute, such as but not limited to between 5 and 175 degrees, more preferably between 45 and 135 degrees, and most preferably between 75 and 105 degrees, such as about 90 degrees.

Abstract
Description
- The invention relates to a catch for a lock, especially for catching a latch of a lock.
- For closing elements, such as but not limited to doors and windows, locks are provided, cooperating with a catch for the latch of the lock. The catch normally comprises a catch plate provided over an opening in a frame, such that the latch can enter into the opening in the frame through an opening in the catch plate. In order to keep the element closed properly the opening in at least the catch plate has to be fit relatively tightly around the latch and has to be positioned relatively accurately relative to the frame in which the opening is made and to which the catch plate is mounted. This means that the mounting of the catch plate and providing the opening is time consuming and costly, and requires skill of the carpenter.
- When the closing element is deformed, for example bend, or displaced, or when for example a seal is ill fitting, the closing element may not fit entirely properly in the frame anymore. Such deformation can for example be the result of environmental issues, such as but not limited to humidity and/or dryness or humidity changes, improper support by its hinges, sagging or other defects of the closing element, its frame and/or its support. When the closing element does not fit in the frame properly anymore it may be come more difficult, if not impossible to get the latch of the lock to enter into the opening in the catch plate and/or frame, or the closing element will otherwise not fit properly in the frame and close the opening in the frame properly.
- The invention has as an aim to provide an alternative catch for the latch of a lock. An alternative aim of the invention is to provide for a solution to at least one of the problems sketched here above. A further alternative aim of the present invention is to provide an assembly for closing at least partly an opening in a frame by a closing element or to be used for such closure. A still further alternative aim of the invention is to provide a method for closing off an opening in a frame by a closure element.
- In a first aspect a catch for a lock latch can be defined by a cup for mounting in or on a frame, having a first side and an opposite second side. A biasing mechanism can be provided within the cup, comprising a displacement element which is biased in the direction of the second side by spring means. An opening shall be provided for inserting part of a latch of a lock which can engage the displacement element such that the displacement element will apply a force on the latch into the direction of the second side.
- In a further aspect a catch can be defined by a cup for mounting in or on a frame, having a first side and an opposite second side. A biasing mechanism can be provided within the cup, comprising a displacement element with a first part adjacent the first side and a second part extending nearer to the second side. A biasing element can be provided adjacent the second side for biasing the first part towards the second side, such that when a force is applied to the side of the first part facing the second side the first part is forced towards the first side and the displacement element will apply a counterforce on the first part.
- An assembly of a catch and a lock with a latch can be characterised by the latch fitting into the cup of the catch, between a first part of the displacement element and a second side of the cup, movable in a direction perpendicular to an insertion direction of the latch into the cup, between the first and second side of the cup. The latch preferably has an at least partly rounded off or tapering side near an end thereof forward in the insertion direction.
- In the present invention a latch of a lock can be a translating type of latch, such as but not limited to latches commonly known as block latches, or pivoting latches. If there is more than one latch, the latches can be of individual locks or of a multiple point lock, centrally operated. A latch can be mechanically and/or electronically operated. In this description insertion direction of a latch has to be understood as including but not limited to a linear movement direction and a pivoting movement direction, relative to the catch. At least in a pivoting movement such direction will be defined by an actual or virtual axis of pivoting of the latch. Also combined linear and pivoting movement can define such insertion direction.
- Another assembly according to the invention can be characterised by a catch according to the invention and a lock with a latch, mounted on a door or window or such closing element, hingedly connected to a frame to and/or into which frame the catch is mounted, wherein the closing element has a pivoting direction towards a closed position within the frame, and wherein the first side of the cup of the catch is positioned at an upstream side of the pivoting direction towards the closed position.
- A method for closing a closing element against a shoulder in a frame by at least a lock and a catch, can be characterised by the catch catching a latch of the lock and forcing part of the closing element towards the shoulder by a displacement element biased towards the shoulder by a biasing element placed, when the closing element is in a closed position, at least partly between the latch and the shoulder.

- In this description embodiments shall be shown and discussed for a door as an example of a closing element. Is shall be clear that also other closing elements can be used, such as but not limited to windows, shutters, hatches and the like. In
fig. 1 a door is shown as an example of a closing element, suspended in a frame, more specifically a doorframe, by hinges to one side and with three sets of cooperating latches and catches for closing the door on the opposite side. These latches can be part of three individual locks or of a centrally operated three point lock. Alternatively there can be only one lock latch or more than one, for example two or more than three. Any lock latch can be a single element such as but not limited to a latch having a substantially square cross section or a pivotable, hooking latch, or can have more than one element, for example a number of pins, extending for example parallel to each other, spaced apart as tines of a fork. Hinges and/or locks can be provided on different sides of the closing element. Similar locks and catches could be provided in different positions, for example between two doors or windows of a double door or window set, or between a door of window and the relevant frame, other than or additionally to the side opposite the hinges. - In the description embodiments are shown in which the latch of a lock can be caught in a catch in and/or on a frame, such that for example misalignments of the latch and the catch relative to each other can be accommodated in at least one direction, especially in a direction substantially perpendicular to the opening area in the frame to be closed by the closing element. The frame has a first side, to or near which the closing element is suspended, and an opposite second side. In embodiments the first side may be referred to as the outer side, the opposite second side as the inner side, for example but not limited to when the closing element is a door or window at an outer side of a building, the closing element turning out for opening. For a closing element turning inward for opening the sides may be reversed. The catch can have a biasing element biasing an element of the catch in a direction towards the second side of the frame, i.e. in a closing direction of the closing element, such that when a latch of a lock connected to the closing element is caught in the catch, said latch and therewith the closing element may be pushed and/or pulled by the biasing element towards the closed position within the frame.
- In the embodiments disclosed the lock or locks with the latches are mounted on and/or in the closing element, the catches in and/or on the frame. However, this can be reversed entirely or in part, the or each lock or at least one thereof being in and/or on the frame and the or each catch or at least one thereof being in and/or on the closing element. In the embodiments shown the catch or catches has/have a longitudinal direction which extends, in mounted position into and/or on a frame, substantially vertically, unless otherwise specified. Obviously, the catches could also mounted differently.
-
Fig. 1 shows aclosing element 1, in this embodiment shown as adoor 1 in aframe 2. Theclosing element 1 is mounted to theframe 2 by a number ofhinges 3. Theframe 2 can be provided, in a known manner, with arabbet 4 providing anabutment 5 for thedoor 1, such that the door can close off the opening within theframe 2. At a side opposite the side comprising thehinges 3 one ormore catches 6 can be provided in or on theframe 2. In the embodiment shown threecatches 6 are provided above each other, for the latches of one or more locks. Thecatches 6 is or are provided such that a latch to be caught by thecatch 6 can easily enter thecatch 6 at least partly and will be forced towards theabutment 5, such that an edge portion of thedoor 1 is forced into close proximity and preferably against the abutment or against aseal 54 provided on or in said abutment, such as a draught and/or sound seal as commonly known. - In the embodiments shown and discussed, for example as shown in
fig. 2 - 5 , acatch 6 can be provided for biasing a latch of a lock or the like in a direction of closure of aclosing element 1. To this end acatch 6 can be provided with acup 7 for mounting in or on aframe 2, having afirst side 8 and an oppositesecond side 9.Cup 7 has to be understood in the description as including at least but not limited to elements having partly open and/or partly closed frames with at least two opposite ends and a hollow or opening between said two opposite ends into which a latch can be entered at least partly. In the embodiment as shown infig. 2 the frame has two relativelylow side walls 18, substantially parallel, and twoopposite end elements 19, connecting thewalls 18, which endelements 19 are higher than thewalls 18. Thus aclosed frame 20 is formed by thewalls 18 and endelements 19, in this embodiment anintegral frame 20. Anopening 21 extends through theframe 20. Theopening 21 can have a closed bottom 22, theopening 21 effectively being a hollow, or can be open to both sides. - A
biasing mechanism 10 can be provided within thecup 7. Thebiasing mechanism 10 can comprise adisplacement element 11, which can be a lever or such type element, with afirst part 12 adjacent thefirst side 8 and asecond part 13 extending nearer to thesecond side 9 than thefirst part 12. At least one biasingelement 14 is provided adjacent thesecond side 9 for biasing thefirst part 12 towards thesecond side 9. When a force F is applied to theside 15 of thefirst part 12 facing thesecond side 9 thefirst part 12 is forced towards thefirst side 8 and thedisplacement element 11 will apply a counterforce FC on thefirst part 12. - In the embodiment shown in
fig. 2 - 5 thedisplacement element 11 is substantially L-shaped in side view, thefirst part 12 forming substantially a first leg of the L, thesecond part 13 forming a second leg of the L. Theelement 11 can for example be set or bend, forced or machined, from a suitable material such as metal or plastic. As can be seen theelement 11 has a length L which is larger than the widths W12, W13 of the first andsecond parts parts connection 23 between the first andsecond part opposite sides - In the embodiment shown the
first part 12 is formed substantially plate shaped, and is at two opposite longitudinal ends provided with asupport 26. Eachsupport 26 is provided with apivot element 27 which can be housed in correspondingopenings 28 in each of therespective end elements 19, for defining a pivotingaxis 29 for theelement 11 relative to thecup 7. Theaxis 29 is positioned near theconnection 23, which connection can be seen as the corner of the substantially L-shapedelement 11. The first part can in some embodiments have amiddle section 30 which is partly cut loose from thefurther part 13, and can be bent slightly towards thefirst side 8 of thecup 7. Aguide element 31, such as but not limited to a low friction element, for example a plastic element, can be mounted on said middle section, for reducing friction and/or wear between a latch and the catch, as shall be explained later on. - The
second part 13 can also be substantially plate shaped and be provided with anopening 32. A latch of a lock can, when entering the cup, extend into and/or through saidopening 32. At twoopposite corners 33 of the second part 13 aspring element 34 can be provided, as a biasingelement 14. Thespring elements 34 can for example be compression springs. Thepart 13 can be provided withspring retaining elements 35, such as notches, preventing side way movements of the spring elements. In another embodiment other biasing elements can be provided, such as coil springs, leaf springs, compressible material and the like. The ends of thespring elements 34 opposite thesecond part 13 can engage acover 36, as will be explained later on. - As can be understood from the above, when in an embodiment of
fig. 2 - 5 thefirst part 12, or at least thefree edge 37 thereof carrying possibly theelement 31, is forced towards thefirst side 8, theelement 11 will pivot around theaxis 29, thus bringing thecorners 33 of thesecond part 13 upward, i.e. towards thecover 36, when mounted, thus compressing thespring element 34, providing for or increasing a counter force on thesecond part 13 and thus the counter force FC, pushing against the force F. This means that an element, such as a latch of a lock, pushing against thefirst part 12 will be pushed toward thesecond side 9 by theelement 11 due to the counterforce FC. - In the embodiment shown the
cover 36 is substantially U-shaped and dimensioned preferably such that it can be mounted over theframe 20, such that the two substantiallyparallel legs 37 of the cover extend between theelements 19 and abut thewalls 18, whereas thewall part 38 of thecover 36, connecting thelegs 37, extends between the upper sides of theelements 19, covering theopening 21. Anopening 39 can be provided in thewall part 38, for allowing alatch 40 of a lock or the like to enter thecatch 6 in the direction M. At least theelement 31 or part of thefirst part 12 of theelement 11 will be exposed below theopening 39, such that alatch 40 can engage theelement 31 and/or thepart 12 as such. Thecover 36 can further be provided with mounting openings and/or elements for securing it to thecup 7 orframe 20 thereof. For example twoopenings 41 can be provided in thecover 36, for allowingbolts 42 to be screwed intonuts 43 provided below slot likeopenings 44 in theend elements 19. Coveringelements 45 can be provided for covering thebolts 42, improving even further on the aesthetics. - The
cup 7, especially theframe 20 can be provided with mountingopenings 46, for example bores extending at an angle through theend elements 19, such thatscrews 49 can be screwed through said bores 46 into theframe 2,front 47 to back 48 of thecup 7, from nearer to thefirst side 8 to nearer or even past thesecond side 9, as is shown infig. 5 . Thecover 36 can cover the heads of thescrews 49 used for mounting thecup 7 to theframe 2. By screwing thescrews 49 or such means into the frame at an angle, the screws are mounted in the body of the frame having sufficient material surrounding thescrews 49, increasing the strength of the mounting. Moreover, the most likely forces to be exerted on thecatch 6 by thelatch 40 will be in an angular direction, which can be similar to the angel of thescrew 49. It should be noted that the angel should be understood as seen with respect to a frontal plane V of theframe 2, parallel to the side of the closing element. - In
fig. 4 A - C schematically the cooperation between alatch 40 and acatch 6 is shown, in three consecutive steps, partly in cross section.. - In
fig. 4A a latch is shown, having afront end 50 entering thecatch 6, especially thecup 7 in the direction I. In this embodiment the latch is conveniently provided with a slightly roundedside 51 at saidend 50 facing thefirst side 8 of thecatch 6. In the position shown infig. 4A theend 50 of thelatch 40 enters thecup 7 through theopening 39 in thecover 36. Theend 50 of thelatch 40, especially therounded side 51 thereof, is moved against theelement 31, or at least against thefirst part 12 of theelement 11. Theelement 11 is biased by thesprings 34 in or to a rest position, as shown infig. 4A . - When the
latch 40 is pushed further into the cup in the direction I, itsend 50 will enter into and through theopening 32 in thesecond part 13 of theelement 11, and theelement 11 will be pivoted around theaxis 29, due to the force F exerted by thelatch 40 on thefirst part 12, through theelement 31 if available. This means that thesecond part 13 is tilted and thecorners 33 thereof are pushed towards theside 38 of thecover 36 opposite the bottom 22 of thecup 7. This means that thespring elements 14, i.e. thesprings 34 are compressed, applying a counter force on theelement 11. This position is shown infig. 4B . - In
fig. 4C thelatch 40 is pushed towards thesecond side 9 of the cup by theelement 11. Thesecond part 13 is pushed back by thespring elements 14, tilting theelement 11 back to its biased rest position, thereby applying the counter force FC on thelatch 40. This will push theclosing element 1 towards and preferably against the abutment of theframe 2. It shall be clear that the movement of the latch and thus of the closing element may be limited by either the play in the direction towards the second side within thecup 7, for example limited by theopening 39, and/or by the play between the edge portion of the closing element and the adjacent abutment of the frame. - As can be seen from
fig. 4 , thelatch 40 shall be moved for example over a distance X corresponding to T1 - T2. - With a catch or several
such catches 6 according to this description the advantage can be obtained that a closing element can be pushed into a closing position by thecatches 6, whereas this catch or these catches may provided for the possibility of correcting for for example misalignment between a lock or latch and a catch, which could exist or come into existence throughout the life time of the closing element, for example due to miscalculations, deformations of the closing element and/or frame or catch, wear of parts of the assembly of closing element, frame, lock or locks and catches, hinges and the like, or due to setting of for example the frame. These misalignments can also change in time, for example due to for example weather or use. Another advantage that can be obtained with a catch or severalsuch catches 6 can be that when closing an element 1 a user does not have to push hard against the closing element, since the cooperating latch(es) and catch(es) will "push" the element into a closed position, if necessary. - As is especially clear form
fig. 3 , the opposite ends of thecup 7, especially of theframe 20 can be defined by theend elements 19, which can be rounded, preferably such that the radius of curvature of theelements 19 is about equal to the overall width of theframe 20, such that an opening or slot or the like for the catch can easily be made in aframe 2 by machining with a tool having the same curvature. Theopening 39 preferably has a length L measured in a direction between theends 19, which is such that alatch 40 can easily be inserted, and which substantially corresponds to the length L1 of the guidingelement 31 on theelement 11. By usingsuch element 31 providing reduced friction the insertion of the latch in the direction I is improved. As can be seen infig. 3 theopening 39 can extend into aleg 37 of thecover 36, at thefirst side 8 of thecup 7, for allowing theelement 31 to move into theopening 39, providing extra space for pivoting of theelement 11 without increasing the overall width Wo of thecup 7. - The distance D between the
side 60 of theframe 2 closest to thefirst side 8 and the side of theelement 11 facing thelatch 40 when inserted can be surprisingly small and/or the thickness T of theframe 2 remaining between saidfirst side 8 and theside 60 of theframe 2 can be sufficiently great. This means that aframe 2 can be used with a limited thickness between theabutment 5 and theside 60 of theframe 2, without compromising the strength of the frame or the mounting of thecatch 6 therein. The angled screws 49 can also aid to this mounting strength, as discussed before. - In
fig. 6 and7 an alternative embodiment of an assembly of acatch 6 and alatch 40 is shown, wherein the catch can be similar to or identical to the catch offig. 2 - 5 , and wherein thelatch 40 is a pivoting latch. Thelatch 40 is mounted on anaxis 60 extending through theopening 61. Agear 62 can be provided, infig. 6 shown in part asteeth 63 which can in a known manner be engaged by a rotating and/or translating part within the lock, which can for example be operated by a key, a lever mechanism, a motor or the like means, known in the art. A rotation of thelatch 40 around saidaxis 60 in the direction indicated byarrow 64 will move a hookingpart 65 of thelatch 40 into and out of thecup 7, especially through theopening 39 in thecover 36, such that part of the hookingpart 65 will hook behind thecover 36, especially behind theedge 66 of theopening 39 closest to a first of theend elements 19. By use of such hookingpart 65 the latch cannot leave thecatch 6 in a linear direction, which can improve anti burglary properties. As can be seen there is aspace 67 behind the cover, between the saidedge 66 and theend element 19 closest thereto, in whichspace 67 the hook part can be accommodated. Theopening 39 is preferably off set relative to a centre C of the catch, in longitudinal direction between bothopposite end elements 19, such thatsuch space 67 is mainly formed to one side of theopening 39. - As can especially be seen from
fig. 7 thehook part 65 can be tapering, chamfered, rounded or the like at a side facing the biasing element, such as theelement 31 or thefirst part 12, in order facilitate such engagement further and reduce the force needed for inserting thehook part 65 of the latch when engaging thedisplacement element 11. - In another aspect the displacement element can have a direction of movement which encloses an angle with the direction of the force to be applied to the latch, which angle is preferably acute, such as but not limited to between 5 and 175 degrees, more preferably between 45 and 135 degrees, and most preferably between 75 and 105 degrees, such as about 90 degrees. Preferably such movement is substantially parallel to a longitudinal direction of the catch.
- In
fig. 8 schematically a first alternative embodiment of acatch 6 is shown, with alatch 40 in cross section, in frontal view and in cross sectional view. In this embodiment the catch comprises aspring leaf 68 asdisplacement element 11. Theleaf spring 68 has a longitudinal direction L with twoopposite end portions end element 19, such that amid section 70 of thespring 68 can be forced outward, i.e. in the direction of afirst side 8 of thecatch 6, when alatch 40 is inserted into the catch, engaging thespring 68 at themid section 70, thereby applying the force F on the spring. The spring will be elastically deformed outward, as shown infig. 8 by a dottedline 70a, allowing for the misalignment of thelatch 40 relative to thecatch 6 in a direction towards thefirst side 8. The force F will be countered by the elastic force of thespring 68, pushing against thelatch 40 in the direction of the second side.Such springs 68 could also be provided on bothsides catch 6, such that a latch could be pushed towards a mid position between thesides sides sides - In
fig. 9 a second alternative embodiment is shown, in which a linearlymoveable displacement element 11 is provided, shown infig. 9 as a bar orstrip 71 having a length direction L with twoopposite end portions end element 19 by linear guides, such that theelement 11 can be forced outward, i.e. in the direction of afirst side 8 of thecatch 6, when alatch 40 is inserted into the catch, engaging theelement 11 at themid section 73, thereby applying the force F on theelement 11. Theelement 11, such as the bar orstrip 71 is biased into the direction of thesecond side 9 of the catch, preferably by biasingmeans 14 such as compression springs 34, which in the embodiment offig. 9 are mounted between thefirst side 8 of thecup 7 or catch 6 and theelement 11. The force F will be countered by the elastic force of thesprings 34, pushing against thelatch 40 in the direction of thesecond side 9. The springs can be mounted near or at theend elements 19. Theelement 11, such as the strip or bar 71 can be stepped in frontal view, such that themid section 73 thereof can be closer to thefirst side 8 than theend portions 72a, b. This can reduce the distance D between thefirst side 8 and the side of themid section 73 facing thelatch 40 when inserted. Alternatively or combined therewith thesprings 34 could be provided between theelement 11 and the opposite second side of the cup or catch, the springs being elongated when theelement 11 is moved towards thefirst side 8. - In
fig. 10A - C a third and fourth alternative embodiment of acatch 6 and latch 40 is shown, in two positions, wherein adisplacement element 11 is shown, as aslide 75 guided within acup 7 or at least aframe 20 having a direction of movement Z substantially parallel to or at a slight angle to the longitudinal direction of thecatch 6, as before defined by theopposite end element 19. Thedisplacement element 75 has aside 76 near thefirst side 8 of thecatch 6 which has a slopingsurface 77, such that upon movement of the latch into the catch, when not entirely properly aligned, a force F will be applied by thelatch 40, the force F being at least partly in a direction as discussed before, towards thefirst side 8, or, when desired, such that such force can be exerted both in the direction of the first orsecond side surface 77 is a side of arectangular opening 78 in theslide 75. However, this can also be provided differently, for example but not limited to aslide 75 having only one side, extending between thefirst side 8 of the catch and a latch, when inserted. A biasingelement 14, such as aspring 34 can be mounted between a longitudinal end portion of theslide 77 and thecup 7 orframe 20, such that a movement of theslide 75 in the direction Z can result in compression or extension of thespring 34 and thus in a resulting counter force FC exerted by theslide 75 on thelatch 40, towards a more properly aligned position. - In
fig. 10A theslide 75 is shown in a first, rest position, wherein the latch is in a properly aligned position, for example near a mid position between the first andsecond side - In
fig. 10B theslide 75 has been moved from the rest position, by thelatch 40 exerting a force F on thesurface 77, compressing thespring 34. Therefore a counter force F will be applied to the latch. - In
fig. 10C a further alternative embodiment is shown, similar to the embodiment offig. 10 A and B , in which theslide 75 can have a substantially rectangular opening into which alatch 40 could fit, which latch could engage a side of said opening, wherein the slopingsurface 77 could be on an outside surface of the slide and/or on thecup 7 orframe 20, such that a longitudinal movement of theslide 75 in the direction Z will push theslide 75 in a direction substantially perpendicular to said direction Z. - As can be seen in the cross sectional views of
fig. 8 -10 again thelatch 40 can have a tapering, chamfered, rounded or otherwiseappropriate end 50 configuration for allowing the latch to engage thespring 68 with saidend 50, reducing the force needed to insert thelatch 40. Thescrews 49 can again be provided in angled slots, for an even further improved mounting of the catch into and/or on aframe 2, as discussed before. Fromfig. 10A - C it will be apparent that a slopingsurface 77 could be provided on either side or both sides of theopening 78, with the same effect. Similarly the other embodiments could be made such that they can perform with forces F working in either direction, i.e. towards or away from the first orsecond side - In the embodiments as shown in
fig. 2 - 5 thedisplacement element 11 is or comprises a lever type element, disclosed as an element which is in cross section substantially L-shaped and pivotable within the catch between a rest position and a pivoted position in which a resilient element such as a spring is compressed, biasing theelement 11 towards the rest position. It shall be clear that the same or similar effects can be obtained with equivalent elements, for the different parts. For example thespring elements corners 33 and the bottom 22 of the cup, or similar solutions. In an alternative embodiment thefirst part 12 could be slidingly mounted in thecup 7, near thefirst side 8, in stead of pivotably mounted, springs being provided between thepart 12 and thecup 7 at the second side, biasing thepart 12 asdisplacement element 11 into the direction of thesecond side 9. Theopening 32 could be left out if the cup is deep enough to accommodate thelatch 40 within thecup 7 between thesecond part 13 and theopening 39. In the embodiments shown the pivotingstumps 27 are provided onsupports 26, which are mounted to theelement 11. These could however also be made integral with theelement 11. - The present invention is by no means limited to the specific embodiments as shown and discussed. Various alternatives are considered to have been disclosed herein too, such as but not limited to combinations of various parts as shown or discussed. These should also be considered falling within the invention as claimed in the appending claims.
