Description

Technical Field of the Invention

The present invention relates to a locking system for use in doors and windows, and more particularly to a strike assembly of the locking system. Said strike assembly allows opening and closing a wing without a door or window handle.

Background of the Invention

In order to open doors and windows in regular use, actuating members are required such as handles or knobs. The locks suitable for use in doors or windows in the state-of-art are configured to be engaged into a housing on the strike structure of a relevant frame, and the lock assembly is used with a suitable handle or knob-like elements. When the door wing is pushed, a latch of the locks used in the doors is received in a corresponding housing in the strike assembly on the frame, which is then closed, and a bolt is engaged into the frame by means of a key or a similar encrypted element so as to complete the locking. In order to unlock a locked door, a suitable key-like encrypted element is also required, while it is necessary to turn the handle down in order to open an unlocked door. This results in a protrusion on the outer side of the door or window. A press is exerted on the handle of the door or window in order to open it, so that the latch is driven into the body and thus locking is deactivated. Once the latch is deactivated, a user in the room pulls the door to himself while a user outside the door pushes same, in order to open it.
The components that are used as the strike assembly in the prior art are mainly mounted to a frame, preferably made of a steel material, such that the bolt and the latch are received therein. In the state of the art, the strike assemblies mainly have a simple structure, and the only function thereof is to be used as a suitable housing structure.
Another example of the prior art is to use locks without a handle. In order to open the doors on which such locks are used, a knob is mounted on the door, and the door can be opened by pulling from the inside or pushing from the outside by means of the knob. Another example of the prior art is that there is a static element in the inner structure of the strike plates without a mechanism. In such locks, after the door is closed, the bolt of the lock is engaged into the door frame by means of a key or knob, thereby locking the door.
A disadvantage of these handles and knobs is that they spread infectious diseases due to the fact that a lot of people touch same in public and social places. In order to prevent this, it is known to use expensive anti-bacterial door handles.
A problem of the prior art is that a means such as a handle, knob etc. is required in door applications for purposes of opening the door. This results in a protrusion on the outer side of the door. Said protrusions extending to the outer side of the door involve the risk that they may strike the limbs of the children, particularly, and also those of the adults. Moreover, the handles and knobs also strike the walls while the door/window is being opened, thereby resulting in permanent deformations both on the wall and on the door.
Another problem in the prior art is that the elements such as handles and knobs that allow opening and closing of the door get rusted in time due to corrosion and cause a unpleasant appearance. This results in maintenance and labour cost. Another problem of the prior art is that slots are made where the elements such as handles and knobs that allow opening and closing of the door are mounted. It is a great time and cost loss for the door manufactures to make said slots. Furthermore, such accessories as handles and knobs that are mounted destroy the overall visual quality of the door and have a negative aesthetical impact on the door.
Still another problem of the prior art is that in all lock applications in the world, the door is opened by pressing an element such as a handle or a knob in order to open it. Therefore, it is inevitable to manually touch such elements as handles and knobs in the existing locking systems. Due to the fact that every person touches the handles, they are hotspots for spreading germs and bacteria. The door handles of the toilets pose a much higher risk to this end. Also, public and social places such as hospitals, schools, cafeterias etc. also have a high risk. Since the door handles are often used by different persons, they are deemed to be a significant factor in spreading diseases because of the germs and bacteria available thereon. Therefore, they pose a great threat to human health. Another problem of the prior art is that anti-bacterial handles are used for sanitary purposes. Said handles are quite expensive and require periodical maintenance. Another problem of the prior art is the trouble experienced in opening of the door when the hands are full. In order to open the door, the user holding an object first puts it on the floor and then presses the door handle to open the door. Once the door is opened, the user grabs the object again and then proceeds through the door. This is both cumbersome and slow.
WO2018006790 (A1 ) discloses a strike assembly comprising a body and a spring-loaded slide element, a follower and an adjustment channel in which a follower pin, which is associated with the follower, is guided and which thus allows determining a position of the slide element.
Another problem of the prior art is that closing of the door by pushing it may be accomplished if the latch is properly fitted into the strike plate hole. Due to the fact that it is sensitive to fit the latch into the strike plate, it is a quite common problem that the door travels back while closing it by pushing same. Still another problem of the prior art is that swing knobs etc. are used in the locks of WCs for locking purposes. It is again necessary to touch them in order to turn same. And this also carries the risk of spreading germs and diseases through touch, as it is the case with handles. Another problem of the prior art is that the latch of the lock strikes the door frame and engages into the lock, and where it coincides with the strike plate hole, it protrudes out. Thus, it causes deformation of the furniture where the latch strikes the door frame, thereby causing an unpleasant appearance and impairing the operating performance. In order to avoid it, elongated strike assemblies may be used, which though increases the cost of the product.

Object of the Invention

Primary object of the present invention is to provide a strike assembly of a locking system which allows opening of a door or a window by touching a wing, to which it is attached internally or externally, without requiring a handle or a knob. In this way, the cost of the components such as handles, rosettes etc. is eliminated and the time spent to mount each component is saved.
Another object of the present invention is to provide a strike assembly which may also be opened by means of a shoulder or foot contact, without requiring a manually-operated element such as door handles or knobs, which thus offers a great advantage where hygiene is important.
Another object of the present invention is to provide a strike assembly which eliminates the burden of the user to leave the load that he holds while entering or exiting the door, thereby ensuring an ease of use.
Another object of the present invention is to provide a strike assembly which, in addition to the comfort offered to the end users, eliminates the use of expensive anti-bacterial handles and knobs that are used in places where hygiene is important, thereby providing cost advantage for the consumer. Furthermore, labour cost and the time spent for mounting handles, rosettes etc. to the door is eliminated.
Another object of the present invention is to provide a strike assembly and a locking system with a lock wherein the strike of the latch to the frame and deformation thereof, as experienced in the existing locks, is eliminated. Thus, deformation of the furniture is also avoided.
Yet another object of the present invention is to provide a locking system which eliminates the problem of travelling back while the door/window wing is being closed.

Summary of the Invention

The present invention, in general, relates to a strike assembly suitable for use with a lock and preferably with a button mechanism, comprising a body and a spring-loaded slide element for rotating, at least partly, about a point where it is engaged, by extending into the body, when in use. Said strike assembly comprises a follower which is associated with the slide element, which is capable of transmitting the motion of the latch thereto, and an adjustment channel in which a follower pin associated with the follower is guided and which thus allows determining a position of the slide element. The strike assembly also comprises a channel adjusting element which is at least party disposed in the adjustment channel and which guides the movement of the said follower pin in the adjustment channel, and a rotary member for determining the position of the channel adjusting member in the adjustment channel and configured to be moved by a latch, when in use.

Detailed Description of the Invention

The invention discloses a lock (80) and a strike assembly (40) for use with a button mechanism (110) for controlling the lock (80). Said strike assembly (40) is suitable for use in a locking system (200) that is suitable for use in windows or doors. With the strike assembly (40) and a locking system (200) to be used therewith, a wing having thereon the same may be pushed and opened from indoor (12) or outdoor (13), thereby describing a system which eliminates the handle of the door/window in the prior art and which is practical, quick and highly hygienic for the user.
The present invention in general relates to a strike assembly (40) suitable for use with a lock (80) and preferably with a button mechanism, comprising a body (43) and a spring-loaded slide element (55) for rotating, at least partly, about a point where it is engaged, by a contact of a latch (90) extending into the body (43), when in use. Said strike assembly (40) comprises a follower (69) which is associated with the slide element (55), which is capable of transmitting the motion of the latch (90) thereto, and an adjustment channel (71) in which a follower pin (63) associated with the follower (69) is guided and which thus allows determining a position of the slide element (55). The strike assembly also comprises a channel adjusting element (75) which is at least party disposed in the adjustment channel (71) and which guides the movement of the said follower pin (63) in the adjustment channel (71), and a rotary member (70) for determining the position of the channel adjusting member (75) in the adjustment channel (71) and configured to be moved by a latch (90), when in use.
The slide element (55) of the present invention is used with an engagement housing (57) to be coupled with a connection protrusion (47) on the body (43), and with a slide element spring (56) which is to be attached to the connection protrusion (47) so as to apply a spring pressure on the slide element (55). As seen in figures 6-11, the slide element (55) is configured to extend along a longitudinal axis on the body (43), and it is rotated at the point, where it is engaged, by virtue of its interaction with the latch, and may retain the said latch (90) therein by means of the slide element housing (58) thereon.
The slide element (55) comprises a slide element housing (58) having at least one inclined surface (59) arranged to retain the latch (90) therein, when in use. At the upper portion of an inclined wall (59) of the slide element housing (58), an upper wall (61), an extension of the inclined wall, is located. The slide element housing (58) has substantially a V-section so as to retain the said latch (90) therein when the wing, to which the lock including the latch (90) and the bolt is attached, is moved into a closed position. The said inclined wall (59) is preferably inclined by 30 to 60 degrees, and by moving the latch (90) on the inclined wall (59), the latch (90) is maintained at desired positions and operation of the system is adjusted.
The slide element (55) can be manufactured as a single part, or may be manufactured by a plurality of components. In the drawings, the slide element (55) which is depicted as including a slide element extension (54) may also be manufactured without the protrusion. In a preferred embodiment of the invention, there is a slide element (55) having a slot (62) thereon, and a connection pin (65) associated with a follower (69) which is guided in the slot (62). The slide element extension (54) is associated with the slide element (55) by means of the recesses and protrusions thereon.
The follower (69) as illustrated in Figure 13, in perspective view, comprises a follower pin body (68) accommodating a follower pin (63) and associated with the follower (69), and a connection pin (65) for engaging the pin body (68) with the follower (69). In an alternative embodiment of the invention, the follower (69) and the connection pin (65) may be manufactured as a single piece, or the follower pin (63) may be engaged with the follower (69) without a follower pin body (68). The follower pin (63) is preferably formed cylindrically and is fixed to a corresponding opening on the follower pin body (68). The pin body (68) is at least partly inserted in a corresponding opening in the follower (69) and the connection pin (65) is then passed through an opening thereon which is formed in a corresponding manner, in order to engage the follower pin body (68) with the follower (69).
With reference to figures 7b-11b, said rotary member (70) comprises a housing to be coupled with a protrusion on the body (43), and there is a rotary member spring (73) on the said protrusion for applying spring pressure on the rotary member (70). With the said spring pressure, the rotary member (70) maintains a pushing protrusion (78), with which it is always in contact with at one end, in the upward direction on a longitudinal axis (Y) of the strike assembly.
The channel adjusting member (75) comprises a channel adjusting member projection (76) guided in the adjustment channel (71) lying linearly on a plurality of and mainly certain axes formed on the body (43). The channel adjusting member projection (76) is mainly present in the adjustment channel (71) so as to move on the longitudinal axis of the strike assembly. As seen in figure 6, the channel adjusting member (75) comprises an adjusting member projection (76) preferably extending in the adjustment channel (71), and a pushing protrusion (78) extending in a slot on the body and suitable to be moved by a contact of the rotary member (70).
With reference to figure 11b, there is an adjusting member projection (76) in the adjustment channel (71) in which the follower pin (63) is guided, which guides or blocks the movement of the follower pin (63) between an intermediate wall (64) and a lower wall (66) located at the lower part and facing to the intermediate wall (64). The adjusting member projection (76) contacts the intermediate wall (64) and the follower pin (63) is pushed from outside of the door in order to block the path of opening (figure 8b), unless the pressure on the rotary member (70) is released. Whenever the rotary member (70) is moved, then the adjusting member projection (76) drops on the intermediate wall (66) upon the release of the pressure, and the follower pin (63) is unblocked and allowed to complete its movement cycle, as shown in figures 10b and 11b. In other words, the channel adjusting member (75) comprises a channel adjusting member projection (76) which rests on the intermediate wall (64) in the adjustment channel (71) when an end of the said spring-loaded rotary member (70) is pressed and which is rotated by the movement of the latch (90), when in use, in order to release the pressure on the channel adjusting member (75) and to thus contact the lower wall (66). Again with reference to figure 6, there is a back cover of the channel adjusting member (77) delimiting the movement in the back side of the body (43) to which the channel adjusting member (75) is connected and suitable to be attached to certain areas on the body (43).
In an embodiment of the invention, the strike assembly (40) and a lock (80) including a latch (90) and a bolt (91) are suitable for use in doors or windows as a locking system. As seen in figure 1, the strike assembly (40) attached to a frame (20) is used with a lock (80) attached to a wing of a window or door (11). In another preferred embodiment of the invention, said lock (80) may be used with a button mechanism (110) contactable by a user, and if the user presses on the relevant buttons on the lock mechanism, the latch (91) may be engaged into a bolt housing (79) on the upper strike plate associated with the body (43). The locking is thus performed. There is a housing on the body (43) corresponding to the bolt housing (79) and enabling partial insertion of the bolt (91).
Next, operation of the invention will be described. In the lock (80) disposed on the wing of the door or window (11), there is a spring-loaded latch (90) movable in a specific channel. If the user desires to close the said wing (11), the latch (90) contacts the slide element (55) which is engaged with the frame (20) at a point and disposed to make a pivotal movement at the point where it is engaged, which is illustrated in the transition from figure 7a to 8a. Due to a contact of the spring-loaded latch (90) that is suitable to move in a specific direction in the lock, said slide element (55) compresses the slide element spring (56) pressing the former, and assumes a wing-closing position by means of the associated mechanism. If a thrust is applied on the indoor (12) or outdoor (13) of the wing (11) from inside or outside, the strike assembly (40) is deactivated and the door is opened.
Briefly, operation of the strike assembly is as follows: the strike assembly (40) engaged with a frame (20) comprises a body (43) and a follower pin (63) associated with the former, a follower (69) associated with the follower pin (63), a slide element (55) transmitting the rotational movement to the follower (69) and a slide element spring (56) for opening the slide element. It also comprises a rotary member (70) for opening the wing (11), when pushed from outdoor (13), and a channel adjusting member (75) associated with the rotary member (70), and a rotary member spring (73) for setting them.
The slide element (55) always urges towards an opened position (as shown in figure 5), due to the associated slide element spring (56). Moreover, the rotary member (70) maintains the channel adjusting member (75) in the closed position, due to the associated rotary member spring (73). An opened position of the strike assembly (40) is illustrated in figures 7a and 7b. The latch (90) of the lock is pushed towards the frame (20), if the wing (11) is to be brought into a closed position, and at the same time, the latch (90) strikes the slide element (55) in the strike assembly (40). This may be exemplified in figure 8a. Said slide element (55) is attached to a connection protrusion (47) on the body (43). The connection protrusion (47) is shaped and sized according to a corresponding hole on the slide element (55), and the slide element (55) is, at least partly, allowed to make a pivotal movement about the said area. When the latch (90) strikes the rotatable slide element (55), the said slide element (55) rotates in the direction of "+M", as shown in the transition from figure 7b to figure 8a, whereas the associated latch (90) is snapped into the slide element housing (58) which preferably has a V-shape, as shown in figures 8a and 8b.
While being rotated by the strike of the latch (90), the said slide element (55) also rotates the associated follower (69) in the direction of +X. The follower (69) transmits the motion to the follower pin (63) associated therewith and guided in an adjustment channel (71), so that the follower pin (63) also moves in the direction +X. The follower pin (63) moves in the upper channel (45) in the adjustment channel (71), thereby following same. The upper channel (45) preferably lies flat and perpendicular to the longitudinal axis of the strike assembly. The path of the adjustment channel (71) is partly straight and partly inclined, by virtue of which the follower pin (63) moves in the direction of -X, when the pressure of the latch (90) is released, and is constrained between the channel adjusting member projection (76) and the intermediate wall (64). Thus, the slide element (55) is constrained in its position. Since the latch of the lock (90) is also engaged into the slide element housing (58), the wing (11) is thus closed.
Closing of a wing of the door or window (11) is illustrated in figures 8a and 8b. The wing of the door (11) maintains its position unless it is pushed from indoor (12) or outdoor (13). Advantageously, the wing (11) may be opened from indoor (12) or outdoor (13) without a door handle. Hereinafter, the way in which the inventive strike assembly (40) is taken into an opened position will be described.
With the said strike assembly (40), opening of the door by pushing any part of the wing (11) from indoor (12) is realised as follows. When the wing is in a closed position, as shown in figures 8a and 8b, the follower pin (63) is maintained between the intermediate wall (64) and the channel adjusting member (75) and the latch (90) is maintained in the slide element housing (58). When the wing (11) is pushed by the user from indoor (12) of the room, the latch (90) also moves in a forward direction +X. Accordingly, the slide element (55) moves in the direction of +M. With the movement of the slide element (55) in the direction of +M, the follower (69) is also moved in the direction of +X. With the movement of the said follower (69) in the direction of +X, the current position of which being shown in figure 9a, the follower pin (63) strikes the inclined channel back wall (49) and is guided. Due to its inclined structure of the back wall (49) with respect to the longitudinal axis of the strike assembly, the follower pin (63) is inserted into the lower channel (48) configured to be linear and perpendicular to the longitudinal axis. Once the follower pin (63) falls on the lower channel (48), the follower pin (63) and thus the slide element (55) are released. The released slide element (55) is quickly opened in the direction of -M due to an impact of the set slide element spring (56). When the slide element (55) is moved and opened in the direction of -M, the follower pin (63) and the latch (90) which are in contact are also moved in the direction of -X. The latch (90) propels the wing (11) to be opened to a certain extent by means of the slide element spring (56). Thus, the latch (90) is released from the slide element (55) and the wing (11) takes the position as shown in figures 7a and 7b. With the said strike assembly (40) of the locking mechanism (80), opening of the door by pushing any part of the wing (11) from indoor (13) is realised as follows.
In the closed position of the wing (11) and when the latch (90) is accommodated in the corresponding housing, as shown in figures 8a and 8b, the follower pin (63) is constrained between the intermediate wall (64) and the channel adjusting member (75) and the latch (90) is constrained in the slide element housing (58). With reference to figures 10a and 10b, if the said wing (11) is pushed from any part thereof from outdoor (13), the latch (90) follows the inclined wall (59) of the slide element (55) and moves in the lock (80) in the direction of +Y and compresses the associated spring (96). Said latch (90) goes up to the upper wall (61) located at the upper portion adjacent to the inclined wall (59). During the movement of the latch (90) on the upper wall (61) which is substantially formed in a flat manner, it strikes the rotary member (70) that is hinged at a specific point, as a result of which the rotary member (70) is rotated anti-clockwise in the direction of +M. When rotated, the rotary member (70) is detached from the channel adjusting member (75), and the pressure thereof that maintains the rotary member (70) in upward direction is removed, so that the adjustment channel (71) and the pushing protrusion (78) in the channel adjusting member (75) are released and fall in the downward direction of -Y. Figure 7b shows a position of the channel adjusting member (75) pressed by the rotary member (70), and figure 10b shows a position of the channel adjusting member projection (76) in the direction of -Y after the rotary member (70) is rotated and its pressure on the channel adjusting member (75) is removed. When the rotary member (70) is rotated, the intermediate wall (64) and the channel adjusting member (75) are spaced apart and thus the follower pin (63) is released. With the release of the follower pin (63) as shown in figure 10b, thanks to the associated slide element spring (56), the slide element (55) is moved in the direction of -M while the follower pin (63) is moved in the direction of -X, which are thus released. While the said follower pin (63) is being returned to its initial position, the latch (90) is released from the slide element (55) and thus the wing (11) is opened as shown in figures 7a and 7b.
As a use example of the inventive strike assembly, once the button (116) is pressed after the door is closed, the bolt (91) is removed from the lock (80) and is inserted in the bolt housing (79) of the strike assembly (40) and thus the associated wing is locked. In this case, even if the wing (11) is pushed from indoor (12) or outdoor (13), the door will not be opened until it is released from the locking position.
Unlocking of a lock (80) in a locked position by withdrawing of the bolt (91) is as follows. When the button (116) is pressed, a triggering member (120) is withdrawn, and when a slide element therein is being returned to its original position, an associated bolt (91) is also removed from the bolt housing (79) and is driven into the body of the lock, thus locking is deactivated. In this case, if the wing (11) is pushed from indoor (12) or outdoor (13), the door or window is opened. The button mechanism (110) for locking may be arranged in the inner side or outer side of the room, or both. It may also be integrated into a key or cylinder. The locking system (200) in general comprises a main body, a latch (90) disposed in the main body and suitable to be received in the strike assembly (40), when in use, and a bolt (91) suitable to be inserted into a corresponding bolt housing (79) in the strike assembly (40), and a spring-loaded bolt housing for accommodating the bolt (91) and configured to be movable. Said strike assembly (40) has a connection plate (42) which is used to attach it, and having thereon a plurality of connection holes. The connection plate preferably has two elongated symmetrical portions, and has an opening for accessing to the slide element (55). There is a bolt housing (79) on the connection plate (42) and there is also a bolt housing on the body (43) corresponding to the bolt housing (42).
The locking unit (200) according to the present invention is suitable for use with a suitable strike assembly (40), so that a system may be achieved which may be opened and closed only by pressing the relevant button (116) and which offers a significant opportunity to use where hygiene is important. Although the latch (90) and the bolt (91) are illustrated as a circular pin in the drawings of the present invention, they may have different forms and dimensions. The latch (90) and the bolt (91) may have different shapes depending on the form of the housing in the strike assembly (40) into which they will be engaged.
