Description
Actuating Bar-Type Lock The present invention relates to an actuating-bar type lock according to the generic term in Claim 1.
When sliding doors are to be latched, it is customary that the shape of the rabetted stile edge of the operating leaf of sliding-door mate with a corresponding face surface in the door frame. Various latching devices are used to this end.
Hooks that are disposed at equal intervals along the height of the door are used extensively for this purpose; these hooks are secured on a thrust or activating bar of an actuating-bar type lock, said bar being supported so as to be able to move longitudinally. When the door is locked, the hooks, which are open at the top or at the bottom, depending on the closing direction, project through corresponding longitudinal openings in a cover plate that is secured to the door frame, and are moved into the latched position by operation of a handle. When this is done, the ends of the hooks, which project from the rabbeted door stile, engage so as to mate with the cover plate positively or by the application of force. However, one significant disadvantage to a design of this type is that the hooks always project from the cover plate, and this can easily lead to injury to a person passing through the door, or to damage to clothing or household articles, particularly when the door is open. Moreover, the protruding hooks are unsightly.
In the case of both sliding doors and hinged doors and windows, operation of the hooks or latches is effected manually, as a rule in the two directions of operation (in the closing and the opening direction), by operating a (rotary) handle. In many applications, it can-be useful if the latches, which have been moved manually into the open position, are first restrained there and then return automatically into their detent position once the door or window has been closed, without the need for further manual intervention. Most of the automatic multi-point latching systems developed to this end incorporate a compression spring that is tensioned when the latches move out of their detent positions. As soon as the latches have reached their end positions by operation of the handle, they are locked in position by means of appropriate detent elements. The handle, which is similarly spring loaded, returns to its starting position by way of idle travel. If the door is now closed, the detent is released by a suitable release mechanism on the door frame and the bolts are moved automatically into their closed position by the compression spring being released. One known solution uses a roller-bearing roller, although such a design is costly, and hard to operate. Other solutions use detent balls that are held in detent cups by means of leaf springs. These, too, are costly designs. In addition, the force required to release them can only be adjusted permanently and with a limited amount of precision.
When sliding doors are to be latched, it is customary that the shape of the rabetted stile edge of the operating leaf of sliding-door mate with a corresponding face surface in the door frame. Various latching devices are used to this end.
Hooks that are disposed at equal intervals along the height of the door are used extensively for this purpose; these hooks are secured on a thrust or activating bar of an actuating-bar type lock, said bar being supported so as to be able to move longitudinally. When the door is locked, the hooks, which are open at the top or at the bottom, depending on the closing direction, project through corresponding longitudinal openings in a cover plate that is secured to the door frame, and are moved into the latched position by operation of a handle. When this is done, the ends of the hooks, which project from the rabbeted door stile, engage so as to mate with the cover plate positively or by the application of force. However, one significant disadvantage to a design of this type is that the hooks always project from the cover plate, and this can easily lead to injury to a person passing through the door, or to damage to clothing or household articles, particularly when the door is open. Moreover, the protruding hooks are unsightly.
In the case of both sliding doors and hinged doors and windows, operation of the hooks or latches is effected manually, as a rule in the two directions of operation (in the closing and the opening direction), by operating a (rotary) handle. In many applications, it can-be useful if the latches, which have been moved manually into the open position, are first restrained there and then return automatically into their detent position once the door or window has been closed, without the need for further manual intervention.

These, too, are costly designs. In addition, the force required to release them can only be adjusted permanently and with a limited amount of precision.
It is an important objective of the present invention to eliminate these and other disadvantages of the prior art using economical means, and to create an actuating-bar type lock~that, when closed, ensures reliable latching of the sliding door and which, in the open position, has no projecting latching elements.
Furthermore, should it be desired, it must be possible to restrain it securely in its open position, and it should be easy to release from its detent position when it is to be closed.
What is attempted is an overall simple design that makes it possible to combine all the components in a small and compact structure. The activating bar lock should be easy to ship, and it should be simple and quick to install.
The main features of the present invention are set out in the descriptive part of Claims 1 and Claim 16. Refinements are the objects of Claims 2 to 15 and Claims 17 to 26.
In an activating bar lock for doors, windows, and the like, in particular for sliding doors, with at least one functional element that can be operated by a drive system, e.g., a push rod, thrust rod, or a slide piece, and which is supported so as to be displaceable behind a cover such as a cover plate or rabbeted stile, and with at least one latching element that is coupled to the functional element, said latching element being, for example, a hook that projects from the cover plate and which, in the closed position, can be moved into positive engagement with a latch plate, the present invention makes provision such that the latching element, when out of its closed position, can be pivoted about a pin that is supported in the functional element and in its longitudinal movement can be lowered, at least partially, behind the cover, perpendicular to the direction of movement of the functional element. This means that the latching elements can be lowered_behind the cover, even as they are being moved from their closed position into the open position, so that when the door leaf is being opened, no latches that could cause injury or damage are projecting from the cover. Manipulation is extremely simple and reliable. There are no problems associated with passing through the door, even when it is only partly open.
According to Claim 2, the latching element is a flat body that passes perpendicularly through the functional element and the cover; the functional element and the cover are provided with elongated slots, the width of which matches the thickness of the latching elements. The latter ensures that the door is always securely latched when in the closed position, and also ensures that the dimensions are compact. The perpendicular arrangement also ensures optimal transfer of force, in particular in the latched position. In all of its functional positions, the latch is optimally guided laterally, and cannot break laterally even when under extreme loads.
The configuration according to Claim 3 provides that under the functional element the latching element is supported from below by a housing block and is guided by a lower edge sliding therein. In addition to this, according to Claim 4, the latching element can retract into the housing block. This simplifies installation and the function of the actuating bar lock within a rabbeted door stile. The housing block, together with the functional elements, can be morticed into wood without any problem. It accommodates the latching element when it retracts, and protects it against external influences. Sliding guidance ensures that the entire mechanism will always operate reliably.
According to Claim 5, from the design standpoint, it is advantageous if the housing block have an elongated body with cams formed in it at the ends, these cams passing through the functional element, the elongated slot of the functional element being provided in each operating direction with widened sections that accommodate the cams. The housing block is simple to install. The functional elements are always guided securely and reliably.
In order to further enhance the lateral guidance of the latching element, according to Claim 6, the housing block incorporates an elongated depression, the width of which matches the elongated slot of the guide element or of the cover.
According to Claim 7, in order to provide additional support or guidance for the latch, this elongated depression can incorporate steps and, at the lower end, incorporate an entry slope. This, too, means that the latching element can be retracted very simply.
In order that the housing block can accommodate the latching element when it is retracted, according to Claim 8, _5_ there is a depression in front of the entry slope, it being preferred that the entry slope continue into this depression.
According to Claim 9, the depression is funnel-shaped to permit the latching element to swing out, and provided with an exit slope opposite the entry slope.
Depending on the configuration of the latching element, in keeping with Claim 10, additional depressions, recesses, or the like can be incorporated in the depression and/or the steps, these parts or part bodies or the latching element being l0 associated.
According to Claim 11, it is an advantage if the housing block be formed in one piece, or made up of two halves that are longitudinally symmetrical, the width of the housing block corresponding, at most, to the width of the functional element. Because of this, the housing block can be manufactured cost effectively and installed with no problems. The small overall dimensions ensure a compact finished size, so that the recess that accommodates the activating bar lock in the leaf of a door does not have to be any wider than for a conventional lock of this kind. For this reason, it is also simple to retrofit the lock according to the present invention.
According to the important version described in Claim 10, there is a pin inserted laterally into the latching element;
this rests in a transverse groove in the elongated slot of the functional element, and rests in the steps of the elongated depression of the housing. In addition to providing for reliable coupling of the latching element with the functional element, this also ensures additional support for the latch within the housing block, as well as its ability to pivot. According to Claim 13, it can also be advantageous if the pin be arranged centrally above the lower edge of the latching element and the lower edge of the latching element make a transition in the opening direction to become a rounded contact edge. The latter ensures that the pivoting process is always initiated reliably, without the latching element becoming twisted or jammed.
According to Claim 14, it is preferred that the latching element be rhomboid, when a U-shaped recess that is parallel to the lower edge can be incorporated in it. The latter serves to ensure that the sliding door is securely latched when closed.
The configuration according to Claim 15 ensures a further improvement of the guidance and function of the latching element. According to this, provision is made such that a second pin is inserted into the latching element from the side; in the closed position, this is located in front of the pivot pin and is of a smaller diameter compared to this.
Another version of the present invention, for which independent protection is claimed, provides--according to Claim 15--that the restraining and release mechanism has a detent element that is coupled with the functional element, said detent element being in the form of a two-arm lever that can pivot about a pin that is supported within the functional element, in the case of an actuating bar lock for windows, doors, or the like, with at least one functional element that can be moved against a restoring force, e.g., an actuating bar, a push rod, or a slide piece that is displaceable longitudinally behind a cover, for example, a cover plate or a rabbeted door stile, with at least one latching element that is coupled to the functional element, which in the closed position can engage with a latch plate so as to mate with it by shape or externally applied force, and with a restraining and releasing system that is arranged along the functional element, with which the functional element can be restrained and by which it can be released with the door is closed. The two-arm lever can thus, in an advantageous manner, perform two functions. One lever arm serves as a detent element that restrains the functional element in a pre-tensioned unlatched position, whereas the detent can be released by the other lever arm. The activating rod lock can be operated very simply the dimensions of the restraining and release device can be kept to a minimum, which greatly simplifies assembly.
To this end, Claim 17 makes provision such that the lever arm is supported so as to be displaceable beneath the cover plate, in a housing block, said housing block having--according to Claim 16--an elongated body with cams formed at its ends;
these cams pass through an elongated slot, said elongated slot being provided in each operating direction with widened sections that accommodate the cams. Thus, the housing block is simple to install. The functional elements are guided reliably.
_g_ According to Claim 19, the housing block incorporates a flat, elongated recess to accommodate and guide the lever; the width of this recess matches the elongated slot of the guide elements. Thus, when required, the lever can be lowered completely into the housing block. In order to achieve the detent effect, Claim 19 also provides that the elongated recess has at its centre a prism-shaped detent depression. According to Claim 20, in order to provide additional support and guidance for the lever, the elongated recess is shaped symmetrically relative to its longitudinal mid-point, while the elongated recess has lateral steps. These also simplify assembly. In addition, provision can also be made such that, in keeping with Claim 21, the housing block is made in one piece or is assembled from two halves that are symmetrical about the longitudinal axis, the width of the housing block corresponding, at the maximum, to the width of the functional element.
In order to enable the lever arm of the lever that is provided as a release lever to be operated from the outside, according to Claim 22, the cover incorporates an elongated slot above the housing block.
According to Claim 23, an additional, important measure according to the present invention is that a pivot pin is inserted into the lever from the side; this is located in a transverse groove in the elongated slot of the functional element, and rests on the steps of the housing's elongated recess. Thus, the lever is directly coupled with the functional element and simultaneously supported so as to be able to pivot.
In addition, Claim 24 provides that lever arms of the lever, which extend on both sides of the pivot pin, are of different lengths, the longer lever arm resting in the housing block opposite the closing direction, and the shorter lever arm resting in the closing direction. The restraining and release forces can be selected in a simple manner by suitable selection of the ratio of the lengths to each other, this further improving manipulation as a whole.
In the configuration according to Claim 25, the lever is acted upon by the force of a spring that, according to Claim 16, acts perpendicular to the elongated recess and, in the closing direction, fits on the lever, above the centre of the prism-shaped depression. As soon as the lever arm of the lever that is formed as the detent element is above the detent depression, the functional element is checked. No additional functional elements are necessary. The spring force can be generated by a leaf spring.
Independent protection is also claimed for another embodiment of the present invention as set out in Claim 27.
According to this, the functional elements and/or the cover are configured separately, the parts of the functional elements each being connected to each other by a coupling shoe so as to shape mate and be secured by friction. To this end, according to Claim 28, the coupling shoe has an essentially rectangular base body with ends in the longitudinal direction that are rounded over, and at least two pins that are fitted into the base.
Additional features, details, and advantages of the present invention are disclosed in the claims and in the following description of embodiments that is based on the drawings appended hereto. These drawings show the following:

Figure 5: An embodiment of an actuating bar coupling.
The actuating bar lock shown in Figure 1a to Figure 1c, which bears the overall reference number 10, is configured for sliding doors. It incorporates a latching element 30 that is actuated by means of a push or actuating bar 12, and when in the closed position (Figure 1b) it engages in a lock plate (not shown herein) secured to a door frame (not shown herein); in the unlatched position (Figure 1c) this latch is held in a retracted position. The actuating bar 12 is installed behind a rabbeted stile or cover plate 20 so as to be displaceable in the longitudinal direction, and is coupled to a a drive system (not shown herein) that is operated by means of a handle.
The latching element 30 is a flat body that passes vertically through the freely displaceable actuating bar 12 and the cover plate 20 in the longitudinal direction. To this end, the latter are provided with elongated slots 13, 22, the widths of which corresponds to the thickness of the latch 30 (see Figure 2b, 2d). The latching element 30 is supported beneath the actuating bar 12 by a housing block 50. This housing block incorporates an elongated body 52 that secures the cover plate 20 on the underside with cams 53 that are formed at its ends. The cams 53 pass through the actuating bar 12 that extends between the upper side 59 of the housing block 50 and the underside of the cover plate 20 so as to be freely displaceable; to this end, the elongated slot 30 in the actuating bar 12 is provided with widened sections 18 in both operating directions. It is preferred that the width of the housing block 50 be approximately equal to the width of the actuating bar 12, so that the housing 50 occupies no extra space within the door. The overall length of the elongated slot 13 in the actuating bar 12 and the length of the housing bar 50 or the space between the guide cams 53 are so dimensioned that the actuating bar 12 always has sufficient longitudinal travel. Additional guide cams (not shown herein) that are arranged along the cover plate 20 and the elongated slot in the actuating bar 12 that is associated with these ensure stable and reliable guidance for the actuating bar system to the 1~ entire height of the door. In order that the latch 30 can be accommodated and guided in the housing block 50, this is provided with an elongated depression 54 into which a lower edge 31 of the latching element 30 can be inserted.
The latching element 30 is coupled to the actuating bar 12 by two transverse pins 32, 34 that are inserted into the flat body 30 from the side, or are made in one piece with this. The first transverse pin 32 (below in Figure 2a) is configured as a pivot pin and is arranged at the approximate mid-point of the lower edge 31 of latch 30. As can be seen in Figure 2, this is shape-mated in a first transverse groove 14 within the elongated slot 13 of the actuating bar and rests with its pin ends (which project from the latch body 30) on two elongated steps 57 that are formed in the housing block 50 on both sides of the elongated depression 54. The second transverse pin 34 is located ahead of the pivot pin 32 in the closing direction (in Figure 2a, above the pivot pin). As a guide pin, its diameter is somewhat smaller than that of the pivot pin 32 and it is installed in a second transverse groove 16 in the actuating bar 12, somewhat higher over the lower edge 31 than the pivot in 32, so that the fulcrum points of both pins 32, 34 that are located beneath the cover plate 20 are at the same level. The space between the pivot pin 32 and the lower edge 31, as well as the diameter thereof, are so selected that the latching element 30 rests with its lower edge 31 in the elongated depression 54 of the housing block 50, while at the same time the pivot pin 32 rests on the side steps 57. As soon as the actuating bar drive moves the actuating bar 12, the pins 32, 34 are engaged by the transverse grooves 14, 15; the latching element 30 tracks each movement of the actuating bar 12 directly, the transverse pins 32, 34 sliding between the cover plate 20 and the housing steps 57. In the intermediate positions shown in Figure 1b, the pin prevents the latch 30 pivoting completely and undesirably around the axis of rotation of the pivot pin 32. The latch 30 is guided securely in each functional position.
As can be seen from Figure 2a and Figure 2c, the latching element 30 is in the general shape of a rhombus with a U-shaped recess 36 that extends parallel to the lower edge 31, and a rear edge 42 that extends obliquely to the lower edge 31 so as to subtend an acute angle with this. The upper arm 37 of the U
of the recess 36 extends so as to be essentially parallel to the lower edge 31, and forms a hook blade that in the closed position of the latching element-30 projects from the elongated slot 22 in the cover plate 20 and engages in the lock plate in the door frame. Because of the rhomboid shape, the lower arm 38 of the U
is shorter than the hook blade 37. In the closed position, the upper edge 39 engages as a hook catch with the cover plate 20. On its lower side, it is also provided with an inclined edge (catch back 40) that extends parallel to the rear edge 42. The transition between the latter and the lower edge is rounded off so that the latch 30 has a rounded end 44. The latching element is thus of the overall form of a bottle opener.
If the hook 30 is loaded in the direction in which the closed sliding door is opened, the hook catch 38 that is located inside and the guide pins 34 that are resting on the underside of the cover plate 20 transfer the tension that is applied from the lock plate onto the hook blade 37 into the rear side of the cover 2o plate 20 as compressive strain. The door is always securely latched. The lock plate and the cover plate 20 are rigidly enclosed by the U-shaped hook ends, the height of the recess 36, i.e., the space between the hook blade 37 and the hook catch 37, corresponding to the thickness of the lock plate and the rabbeted door stile, apart from a small amount of clearance. Thus, the latching element 30 can always engage in the lock plate without any problem. The unattached end of the hook blade 30 is configured so as to be slightly conical.
As is shown in Figure 2a and Figure 2c, the elongated depression 54 within the housing block 50 extends in the closing direction of the latching element 30, beyond the upper end of the elongated slot 22 in the cover plate 20 so that when the door is latched the hook catch 38 comes to rest completely beneath the cover plate 20. In the opposite direction, the elongated depression 54 becomes an entry slope 58. This begins just above the outer back 60 of the housing block 50 and ends in front of the lower end of the elongated slot 22 at the level of the cover plate 20, i.e., it extends obliquely downward to the right opposite the closing direction of the latch 30, with the slope 58 subtending the same angle with the cover plate 20 as the rear edge 42 of the latching element 30 subtends with its lower edge 31. Ahead of the transition to the entry slope 58, the elongated depression 54 in the housing block 50 is provided with an additional depression 62 to accommodate the retracted hook catch 38. This depression 62 also extends to a point just above the outer back 60 of the housing 50, and is defined upward in the closing direction by an additional inclined face 64. As is shown in Figure 2a or Figure 2c this can also be open below so as to further reduce the installed height of the housing 50 and thus of the entire latching device. At the same level as the catch depression 62 there are recesses 66 in the side steps 57 of the housing block 50; these accommodate the guide pin 34 when it is pivoted.
Figure la and Figure 2a show the latch hook 30 in the closed position, whereas Figure lb indicates the opening movement of the actuating bar lock 10. The actuating bar 12 slides downward between the lower side of the cover plate 20 and the upper side 59 of the housing block 50. In so doing, it moves the latch hook 30 that is installed in the transverse slot 14 with it and slides it in the opening direction within the elongated slot 22 in the cover plate 20. The hook blade 37 moves out of engagement with the lock plate; the straight lower edge 31 of the latching element 30 slides on the base surface 58 of the elongated depression 54 of the housing block 50 that is parallel to the cover plate, so that the hook 30 retains its original position, i.e., there is still no rotation of the hook 30 (see Figure lb). The guide pin 34 that slides along beneath the cover plate 20 prevents any unintentional lifting of the latch 30 during this linear movement.
Once the rounded, rear and 44 of the latch reaches the entry slope 56, it is compelled to slide along this until the lower edge 31 of the latching element 30 comes to rest flat against the entry slope 58. This means that the latch 30 is automatically pivoted about its pivot pin 32. The hook blade 37 disappears behind the cover plate 20. The guide pins 34 retract into the symmetrical depressions 66 in the side steps, whereas the hook catch 38 drops into the recess 62 in the base surface 56 of the elongated depression 54. There is a further depression 66 for the hook blade 37 above the depression 62 for the hook catch 38, so that the latching element 30 pivots through the cover plate 20 and the actuating bar 12 pivots almost completely into a hook bed. As can be seen from Figure lc and Figure 2c, in this end position, the rear edge 42 of the latch 40 is almost flush with the cover plate 20. The back surface 40 of the hook catch 38 is flush with the outer back surface 60 of the housing block 50 (Figure 2).
l0 If one moves the actuating bar 12 in the opposite direction, i.e., in the closing direction, the hook catch 38 of the latching element 30 moves onto the similarly inclined upper inclined surface 64 of the depression 62. The catch back 40 slides along the inclined surface 64 in the direction of the cover plate 20, so that the latch 30 is once again pivoted about its pivot pin 32 until the guide pins 34 come to rest against the cover plate 20. The hook blade 37 is completely extended and now slides once again parallel to the cover plate 20 into its lock position.
In order to improve the manner in which the hook 30 is guided, and in order to enhance the reliability of the closed position even further, the steps 57 that are formed on both sides of the elongated depression 54 in the housing block 50 are configured like terraces. As can be seen in Figure 2a, in the lower area of the housing block 50, the steps 57 first run beneath the upper side 59. At the level of the depression 67, the steps 57 run over a slightly inclined surface 61 into the upper side 59. In this way, as they approach the closed position, the guide pins 34 are raised slightly so that--together with the pivot pin 52--they rest directly against the underside of the cover plate 20. In contrast to this, the pivot pin 32 comes to rest just in front of the inclined surface 61, and so does not get raised.
Should it be necessary, a plurality of latching devices of this kind can be arranged along the actuating bar 12 or the cover plate 20. This will depend on the number of places at which a door is to be latched.
The manner in which the latch device according to the present invention operates is shown diagrammatically in Figure 2a to Figure 2c. Figure 2a shows the hook 30 extended longitudinally and transversely, as it would be when the sliding door is closed and it is in engagement with the lock plate. When the latch is open, the hook 30 is moved by the actuating bar 12 as it moves longitudinally; the actuating bar 12 is covered by the cover plate 20 that is screwed to the rabbeted stile of the door. The hook 30 is raised and lowered perpendicularly to the movement of a actuating bar by sliding edges 31, 40, 44 on the underside, front and back of the hooks and corresponding entry slopes 58, 64 in the hook bed, the cross-section of which is matched to the cover slot 22. The entry slopes 58, 64 together with the rounded hook end 44 and the hook catch 38, 40 thus form control elements that determine the functional movement of the hook. The latching element 30 can also be in the form of a two-arm lever that is supported so as to be able to pivot about the pivot pin 32. The first lever arm forms the hook blade 37, whereas the second shorter lever arm is formed by the back corner 44. The latter serves as the release element for retracting the latch 30.
If the actuating bar 12 is moved longitudinally in order to open the door, the hook 30 is first disengaged from the lock plate over two-thirds of the travel of the actuating bar as in Figure lb, like a conventional and non-retracted hook during a purely longitudinal movement, before it is moved through the cover plate 20 and the actuating bar 12 into the bed of the housing block 50 during the last third of the actuating bar travel, as is shown in Figure 1 c to Figure 2c, respectively. In this end position, the rear edge 42 of the hook 30 is almost completely flush with the cover plate 20.
In another embodiment, in addition to the latching devices described above, the actuating bar lock 10 has an additional restraining and release mechanism 100. This serves to restrain the actuating bar 12 in the unlatched position of the latching element 30 and, once the door has been closed, to release it automatically in order that the latching elements 30, which are spring-loaded in the closing direction, can return to their latched positions automatically. To this end, within the actuating bar drive system (not shown herein), there is a compression spring that is pretensioned when the handle (not shown herein) is operated. As soon as the latching elements 30 have reached their retracted end positions and the spring has been pretensioned to the maximum extent possible, the actuating bar 12 is fixed in its position by the restraining and release device. The rotary handle (not shown herein) then free-wheels back to its starting position.
The restraining and release device 100 that is shown in Figure 3a to Figure 3c is arranged along the actuating bar 12 above a latching device. It has a detent element 130 that is positively coupled to the actuating bar 12 and is in the form of a two-arm lever. When the latching element 30 reaches a specific position, a first lever arm 132 passes through the actuating bar 12 and the cover plate 20 in the longitudinal direction, whereas a second shorter lever arm 134 fits into a corresponding detent depression 158 in the bottom 155 of a housing block 150. The actuating bar 12 and the cover plate 20 incorporate elongated slots 135 or 140, respectively, to allow passage of the lever 130, and the widths of these elongated slots corresponds to the thickness of the lever 130.
The lever 130 that is of square or rectangular cross section is supported beneath the cover plate 20 in the housing block 150 so as to be displaceable in the longitudinal direction (Figure 3a). The latter has an elongated body 152 that is secured to the cover plate 20, preferably by screws. The cams 153 pass through the actuating bar 12 that extends between the housing 2~ block 150 and the cover plate 20, and which is freely displaceable; to this end, the longitudinal elongated slot 135 of the actuating bar 12 is provided with widened sections 138 in each operating direction. The width of the housing block 150 is about the same as the width of the actuating bar 12, so that there is a minimal requirement for space. The overall length of the elongated slots 135-in the actuating bar 12 and the length of the housing block 150 or the space between the guide cams 153 is such that there can always be sufficient longitudinal displacement of the actuating bar 12. A flat elongated recess 154 is provided within the housing block 150 to accommodate and guide the lever 130, and the lever 130 is installed flat in this. For reasons of assembly, the entire housing block 150 is formed so as to be symmetrical with reference to its longitudinal centre. Thus it can be secured to the cover plate 20 in any direction. The elongated slot 140 of the cover plate 20 is flush above the lower half of the long elongated recess 154. Its width is matched to the width of the lever or of the elongated recess 135 of the actuating bar 12.
The lever 130 is coupled to the actuating bar 12 through a transverse pin 142 that, as a pivot body, is installed in the lever 130 from the side or is made in one piece with this.
As can be seen in Figure 3b, the pin 142 is located between the first, longer lever arm 132 and the second, shorter lever arm 134; it is expedient that these be made in one piece. As shown in Figure 3b, the pin 142 is shape mated to, and fits in, a transverse groove 136 in the elongated slot 135 in the actuating bar and lies with its pin ends that project to the side on two elongated steps 157 that are formed on both sides of the elongated recess 154 in the housing block 150. From the other side, the pin 142 is protected by the cover plate 20 that lies over the actuating bar 12.
In the closed-position, the lever 130 lies flat on the bottom 155 of the elongated recess 154 of the block 150, 152, while the pivot pins 142 rest on the side steps 157. The second, shorter lever arm 134 lies in the closing direction, and the second, longer lever arm 132 lies opposite the closing direction in the housing block 150. As soon as the actuating bar 12 is moved by means of the actuating bar drive system, the pin 142 is engaged by the transverse groove 136; the lever 130 tracks every movement of the actuating bar 12 directly within the housing 150, the pivot pin ends sliding between the cover plate 20 and the housing steps 157.
The detent depression 158 for the lever arm 134 is provided in the precise centre of the housing block 150. This is a prism-shaped depression that is made in the bottom 155 of the elongated recess 154. The length of the elongated recess 154 is approximately twice as large as the overall length of the lever 130. A leaf spring 170 is arranged between this and the cover plate 20 within the upper widened section 138 in the elongated slot of the actuating bar 12. This spring is installed with an offset end 172 in a clamping slot 174 in the housing block 150.
Its unattached end 175 is exactly over the upper half of the prism-shaped depression 158 on the lever 138. Thus, it is constantly acted upon by a spring force in the direction of the housing bottom 155 through the depression 158.
When the latching element 30 is in its closed position, the lever 130 first lies flat beneath the cover plate 20 in the elongated reasons 154 of the housing block 150 (Figure 3a). The unattached, slightly offset end 175 of the leaf spring 170 lies on the long lever arm 130.
If the latching element 30 is actuated by means of the handle, the actuating bar 12 slides downward between the cover plate 20 and the housing block 150. In so doing, it takes the lever 130 that is installed in the transverse slot 136 with it and moves it within the elongated depression 154 downward in the opening direction. Just before the latching elements 30 reach the final open position, the pivot pin 142 of the lever 130 passes the contact point of the leaf spring 170. As soon as this moves behind the pivot pin 142, the spring 170 acts on the shorter lever arm 134 that is following behind the longer lever arm 132.
Since, because of its shorter dimensions, this is now, like the unattached end 175 of the leaf spring 170, above the detent depression 158, it is pushed downwards and into the depression 158 by the spring 170, and held their (see Figure 3c). In order to achieve a more reliable detent, the end of the lever 304 is inclined slightly corresponding to the opening angle for the shape of the prism-shaped depression 158, so that the end of the lever hooks into the detent depression 158 and the actuating bar is restrained firmly in the position that it has reached against the actuating bar return spring. At the same time as the short lever arm 134 engages in the detent depression 158, the first, longer lever arm 132 passes to the outside through the openings 135, 140 of the actuating bar 12 and the cover plate 20. Because of the permanent spring-loading of the short shorter lever arm 134, the exposed lever 132 will be held in this position. The latching element 30 are in their retracted position; the door can be opened without any potentially dangerous latching hooks projecting from the outside side surface of the door stile.
If one closes the door, then the rabbeted side surface of the door stile moves against the corresponding face of the door frame. The lever arm 132 that is projecting from the cover plate 20 now serves as a release. It is pivoted inward about the pivot pin 142, so that the end of the second lever arm 134 is raised out of the prism-shaped depression 158 in the housing bottom 155. The detent is released; the actuating bar 12 can once again slide freely in the closing direction. The latching element 30 that are attached to the actuating bar 12 are moved into their detent positions by the return force that is stored in the actuating bar drive system. On closing, the door is automatically latched. The amount of force required to release the detent can be so adjusted by suitable selection of the ratio of the lengths of the lever arms 132 and 134 that the restraining and release device 100 does not hinder the closing of the door although, at the same time, unintentional release of the detent is effectively prevented.
Yet another embodiment of the present invention, shown in Figure 5, permits simple shipping and simple and rapid assembly of the actuating bar lock 10.
It is frequently useful to manufacture actuating bar 12 and cover plate 20 divided into a number of sections. The parts, disassembled for shipping, are then assembled on site and installed. Whereas the sections of the cover plate require no connection to each other since they are screwed rigidly into the rabbeted groove, the sections of the activating are must be secured rigidly to each other in order that they can slide freely within the door groove.
The coupling shoe 200 that is required to connect the sections of actuating bar, shown in Figure 5, incorporates an elongated and essentially rectangular base body 202. On the underside of the base body 202 are four round pins 204 that are aligned; these are inserted into the base body to or made in one piece with it. On the opposite side, the base body is rounded over at the ends 206 in the longitudinal direction.
During assembly of the actuating bar lock 10, two pins 204 of the coupling shoe 200 are inserted into corresponding recesses 208 in the particular actuating bar end 207; these are pressed into the bores 208 so as to form a friction fit. This ensures a permanently secure connection whereas the arrangement of the pins 104 in a line ensures precise orientation of the coupling shoe 200 and the actuating bar 12. Since the base body 202 of the coupling shoe 200 is enclosed on all sides by the door, it cannot fall out of the bores 208 even after a long period of use. The rounded ends 206 ensure permanently easy longitudinal movement within the door groove. In addition to ease of operation and assembly, as well as reliable operation, the coupling piece 200 entails an additional but important advantage.
The actuating bar lock 10 can be used unmodified at any time without operating bar extensions, i.e., with only the permanently installed central plate since, in contrast to the prior art, the ends of the lock side actuating bar are in each instance covered by the cover plate.
The present invention is not confined to the embodiment described heretofore, but can be modified in a number of ways.
For example, the housing blocks 50, 150 as well as the latching device and the restraining device can be made in one piece. They can also be assembled from two symmetrical housing halves that are provided with the appropriate symmetrical and mirror image recesses and bolted securely to each other.
All of the features and advantages, including design details, spatial arrangements, and process steps set out in the claims, the disclosure, and the drawings are essential to the present invention, both singly and in the most varied combinations.

Furthermore, should it be desired, it must be possible to restrain it securely in its open position, and it should be easy to release from its detent position when it is to be closed.
What is attempted is an overall simple design that makes it possible to combine all the components in a small and compact structure. The activating bar lock should be easy to ship, and it should be simple and quick to install.
The main features of the present invention are set out in the descriptive part of Claims 1 and Claim 16. Refinements are the objects of Claims 2 to 15 and Claims 17 to 26.
In an activating bar lock for doors, windows, and the like, in particular for sliding doors, with at least one functional element that can be operated by a drive system, e.g., a push rod, thrust rod, or a slide piece, and which is supported so as to be displaceable behind a cover such as a cover plate or rabbeted stile, and with at least one latching element that is coupled to the functional element, said latching element being, for example, a hook that projects from the cover plate and which, in the closed position, can be moved into positive engagement with a latch plate, the present invention makes provision such that the latching element, when out of its closed position, can be pivoted about a pin that is supported in the functional element and in its longitudinal movement can be lowered, at least partially, behind the cover, perpendicular to the direction of movement of the functional element. This means that the latching elements can be lowered_behind the cover, even as they are being moved from their closed position into the open position, so that when the door leaf is being opened, no latches that could cause injury or damage are projecting from the cover. Manipulation is extremely simple and reliable. There are no problems associated with passing through the door, even when it is only partly open.
According to Claim 2, the latching element is a flat body that passes perpendicularly through the functional element and the cover; the functional element and the cover are provided with elongated slots, the width of which matches the thickness of the latching elements. The latter ensures that the door is always securely latched when in the closed position, and also ensures that the dimensions are compact. The perpendicular arrangement also ensures optimal transfer of force, in particular in the latched position. In all of its functional positions, the latch is optimally guided laterally, and cannot break laterally even when under extreme loads.
The configuration according to Claim 3 provides that under the functional element the latching element is supported from below by a housing block and is guided by a lower edge sliding therein. In addition to this, according to Claim 4, the latching element can retract into the housing block. This simplifies installation and the function of the actuating bar lock within a rabbeted door stile. The housing block, together with the functional elements, can be morticed into wood without any problem. It accommodates the latching element when it retracts, and protects it against external influences. Sliding guidance ensures that the entire mechanism will always operate reliably.
According to Claim 5, from the design standpoint, it is advantageous if the housing block have an elongated body with cams formed in it at the ends, these cams passing through the functional element, the elongated slot of the functional element being provided in each operating direction with widened sections that accommodate the cams. The housing block is simple to install. The functional elements are always guided securely and reliably.
In order to further enhance the lateral guidance of the latching element, according to Claim 6, the housing block incorporates an elongated depression, the width of which matches the elongated slot of the guide element or of the cover.
According to Claim 7, in order to provide additional support or guidance for the latch, this elongated depression can incorporate steps and, at the lower end, incorporate an entry slope. This, too, means that the latching element can be retracted very simply.
In order that the housing block can accommodate the latching element when it is retracted, according to Claim 8, _5_ there is a depression in front of the entry slope, it being preferred that the entry slope continue into this depression.
According to Claim 9, the depression is funnel-shaped to permit the latching element to swing out, and provided with an exit slope opposite the entry slope.
Depending on the configuration of the latching element, in keeping with Claim 10, additional depressions, recesses, or the like can be incorporated in the depression and/or the steps, these parts or part bodies or the latching element being l0 associated.
According to Claim 11, it is an advantage if the housing block be formed in one piece, or made up of two halves that are longitudinally symmetrical, the width of the housing block corresponding, at most, to the width of the functional element. Because of this, the housing block can be manufactured cost effectively and installed with no problems. The small overall dimensions ensure a compact finished size, so that the recess that accommodates the activating bar lock in the leaf of a door does not have to be any wider than for a conventional lock of this kind. For this reason, it is also simple to retrofit the lock according to the present invention.
According to the important version described in Claim 10, there is a pin inserted laterally into the latching element;
this rests in a transverse groove in the elongated slot of the functional element, and rests in the steps of the elongated depression of the housing. In addition to providing for reliable coupling of the latching element with the functional element, this also ensures additional support for the latch within the housing block, as well as its ability to pivot. According to Claim 13, it can also be advantageous if the pin be arranged centrally above the lower edge of the latching element and the lower edge of the latching element make a transition in the opening direction to become a rounded contact edge. The latter ensures that the pivoting process is always initiated reliably, without the latching element becoming twisted or jammed.
According to Claim 14, it is preferred that the latching element be rhomboid, when a U-shaped recess that is parallel to the lower edge can be incorporated in it. The latter serves to ensure that the sliding door is securely latched when closed.
The configuration according to Claim 15 ensures a further improvement of the guidance and function of the latching element. According to this, provision is made such that a second pin is inserted into the latching element from the side; in the closed position, this is located in front of the pivot pin and is of a smaller diameter compared to this.
Another version of the present invention, for which independent protection is claimed, provides--according to Claim 15--that the restraining and release mechanism has a detent element that is coupled with the functional element, said detent element being in the form of a two-arm lever that can pivot about a pin that is supported within the functional element, in the case of an actuating bar lock for windows, doors, or the like, with at least one functional element that can be moved against a restoring force, e.g., an actuating bar, a push rod, or a slide piece that is displaceable longitudinally behind a cover, for example, a cover plate or a rabbeted door stile, with at least one latching element that is coupled to the functional element, which in the closed position can engage with a latch plate so as to mate with it by shape or externally applied force, and with a restraining and releasing system that is arranged along the functional element, with which the functional element can be restrained and by which it can be released with the door is closed. The two-arm lever can thus, in an advantageous manner, perform two functions. One lever arm serves as a detent element that restrains the functional element in a pre-tensioned unlatched position, whereas the detent can be released by the other lever arm. The activating rod lock can be operated very simply the dimensions of the restraining and release device can be kept to a minimum, which greatly simplifies assembly.
To this end, Claim 17 makes provision such that the lever arm is supported so as to be displaceable beneath the cover plate, in a housing block, said housing block having--according to Claim 16--an elongated body with cams formed at its ends;
these cams pass through an elongated slot, said elongated slot being provided in each operating direction with widened sections that accommodate the cams. Thus, the housing block is simple to install. The functional elements are guided reliably.
_g_ According to Claim 19, the housing block incorporates a flat, elongated recess to accommodate and guide the lever; the width of this recess matches the elongated slot of the guide elements. Thus, when required, the lever can be lowered completely into the housing block. In order to achieve the detent effect, Claim 19 also provides that the elongated recess has at its centre a prism-shaped detent depression. According to Claim 20, in order to provide additional support and guidance for the lever, the elongated recess is shaped symmetrically relative to its longitudinal mid-point, while the elongated recess has lateral steps. These also simplify assembly. In addition, provision can also be made such that, in keeping with Claim 21, the housing block is made in one piece or is assembled from two halves that are symmetrical about the longitudinal axis, the width of the housing block corresponding, at the maximum, to the width of the functional element.
In order to enable the lever arm of the lever that is provided as a release lever to be operated from the outside, according to Claim 22, the cover incorporates an elongated slot above the housing block.
According to Claim 23, an additional, important measure according to the present invention is that a pivot pin is inserted into the lever from the side; this is located in a transverse groove in the elongated slot of the functional element, and rests on the steps of the housing's elongated recess. Thus, the lever is directly coupled with the functional element and simultaneously supported so as to be able to pivot.
In addition, Claim 24 provides that lever arms of the lever, which extend on both sides of the pivot pin, are of different lengths, the longer lever arm resting in the housing block opposite the closing direction, and the shorter lever arm resting in the closing direction. The restraining and release forces can be selected in a simple manner by suitable selection of the ratio of the lengths to each other, this further improving manipulation as a whole.
In the configuration according to Claim 25, the lever is acted upon by the force of a spring that, according to Claim 16, acts perpendicular to the elongated recess and, in the closing direction, fits on the lever, above the centre of the prism-shaped depression. As soon as the lever arm of the lever that is formed as the detent element is above the detent depression, the functional element is checked. No additional functional elements are necessary. The spring force can be generated by a leaf spring.
Independent protection is also claimed for another embodiment of the present invention as set out in Claim 27.
According to this, the functional elements and/or the cover are configured separately, the parts of the functional elements each being connected to each other by a coupling shoe so as to shape mate and be secured by friction. To this end, according to Claim 28, the coupling shoe has an essentially rectangular base body with ends in the longitudinal direction that are rounded over, and at least two pins that are fitted into the base.
Additional features, details, and advantages of the present invention are disclosed in the claims and in the following description of embodiments that is based on the drawings appended hereto. These drawings show the following:

Figure 5: An embodiment of an actuating bar coupling.
The actuating bar lock shown in Figure 1a to Figure 1c, which bears the overall reference number 10, is configured for sliding doors. It incorporates a latching element 30 that is actuated by means of a push or actuating bar 12, and when in the closed position (Figure 1b) it engages in a lock plate (not shown herein) secured to a door frame (not shown herein); in the unlatched position (Figure 1c) this latch is held in a retracted position. The actuating bar 12 is installed behind a rabbeted stile or cover plate 20 so as to be displaceable in the longitudinal direction, and is coupled to a a drive system (not shown herein) that is operated by means of a handle.
The latching element 30 is a flat body that passes vertically through the freely displaceable actuating bar 12 and the cover plate 20 in the longitudinal direction. To this end, the latter are provided with elongated slots 13, 22, the widths of which corresponds to the thickness of the latch 30 (see Figure 2b, 2d). The latching element 30 is supported beneath the actuating bar 12 by a housing block 50. This housing block incorporates an elongated body 52 that secures the cover plate 20 on the underside with cams 53 that are formed at its ends. The cams 53 pass through the actuating bar 12 that extends between the upper side 59 of the housing block 50 and the underside of the cover plate 20 so as to be freely displaceable; to this end, the elongated slot 30 in the actuating bar 12 is provided with widened sections 18 in both operating directions. It is preferred that the width of the housing block 50 be approximately equal to the width of the actuating bar 12, so that the housing 50 occupies no extra space within the door. The overall length of the elongated slot 13 in the actuating bar 12 and the length of the housing bar 50 or the space between the guide cams 53 are so dimensioned that the actuating bar 12 always has sufficient longitudinal travel. Additional guide cams (not shown herein) that are arranged along the cover plate 20 and the elongated slot in the actuating bar 12 that is associated with these ensure stable and reliable guidance for the actuating bar system to the 1~ entire height of the door. In order that the latch 30 can be accommodated and guided in the housing block 50, this is provided with an elongated depression 54 into which a lower edge 31 of the latching element 30 can be inserted.
The latching element 30 is coupled to the actuating bar 12 by two transverse pins 32, 34 that are inserted into the flat body 30 from the side, or are made in one piece with this. The first transverse pin 32 (below in Figure 2a) is configured as a pivot pin and is arranged at the approximate mid-point of the lower edge 31 of latch 30. As can be seen in Figure 2, this is shape-mated in a first transverse groove 14 within the elongated slot 13 of the actuating bar and rests with its pin ends (which project from the latch body 30) on two elongated steps 57 that are formed in the housing block 50 on both sides of the elongated depression 54. The second transverse pin 34 is located ahead of the pivot pin 32 in the closing direction (in Figure 2a, above the pivot pin). As a guide pin, its diameter is somewhat smaller than that of the pivot pin 32 and it is installed in a second transverse groove 16 in the actuating bar 12, somewhat higher over the lower edge 31 than the pivot in 32, so that the fulcrum points of both pins 32, 34 that are located beneath the cover plate 20 are at the same level. The space between the pivot pin 32 and the lower edge 31, as well as the diameter thereof, are so selected that the latching element 30 rests with its lower edge 31 in the elongated depression 54 of the housing block 50, while at the same time the pivot pin 32 rests on the side steps 57. As soon as the actuating bar drive moves the actuating bar 12, the pins 32, 34 are engaged by the transverse grooves 14, 15; the latching element 30 tracks each movement of the actuating bar 12 directly, the transverse pins 32, 34 sliding between the cover plate 20 and the housing steps 57. In the intermediate positions shown in Figure 1b, the pin prevents the latch 30 pivoting completely and undesirably around the axis of rotation of the pivot pin 32. The latch 30 is guided securely in each functional position.
As can be seen from Figure 2a and Figure 2c, the latching element 30 is in the general shape of a rhombus with a U-shaped recess 36 that extends parallel to the lower edge 31, and a rear edge 42 that extends obliquely to the lower edge 31 so as to subtend an acute angle with this. The upper arm 37 of the U
of the recess 36 extends so as to be essentially parallel to the lower edge 31, and forms a hook blade that in the closed position of the latching element-30 projects from the elongated slot 22 in the cover plate 20 and engages in the lock plate in the door frame. Because of the rhomboid shape, the lower arm 38 of the U
is shorter than the hook blade 37. In the closed position, the upper edge 39 engages as a hook catch with the cover plate 20. On its lower side, it is also provided with an inclined edge (catch back 40) that extends parallel to the rear edge 42. The transition between the latter and the lower edge is rounded off so that the latch 30 has a rounded end 44. The latching element is thus of the overall form of a bottle opener.
If the hook 30 is loaded in the direction in which the closed sliding door is opened, the hook catch 38 that is located inside and the guide pins 34 that are resting on the underside of the cover plate 20 transfer the tension that is applied from the lock plate onto the hook blade 37 into the rear side of the cover 2o plate 20 as compressive strain. The door is always securely latched. The lock plate and the cover plate 20 are rigidly enclosed by the U-shaped hook ends, the height of the recess 36, i.e., the space between the hook blade 37 and the hook catch 37, corresponding to the thickness of the lock plate and the rabbeted door stile, apart from a small amount of clearance. Thus, the latching element 30 can always engage in the lock plate without any problem. The unattached end of the hook blade 30 is configured so as to be slightly conical.
As is shown in Figure 2a and Figure 2c, the elongated depression 54 within the housing block 50 extends in the closing direction of the latching element 30, beyond the upper end of the elongated slot 22 in the cover plate 20 so that when the door is latched the hook catch 38 comes to rest completely beneath the cover plate 20. In the opposite direction, the elongated depression 54 becomes an entry slope 58. This begins just above the outer back 60 of the housing block 50 and ends in front of the lower end of the elongated slot 22 at the level of the cover plate 20, i.e., it extends obliquely downward to the right opposite the closing direction of the latch 30, with the slope 58 subtending the same angle with the cover plate 20 as the rear edge 42 of the latching element 30 subtends with its lower edge 31. Ahead of the transition to the entry slope 58, the elongated depression 54 in the housing block 50 is provided with an additional depression 62 to accommodate the retracted hook catch 38. This depression 62 also extends to a point just above the outer back 60 of the housing 50, and is defined upward in the closing direction by an additional inclined face 64. As is shown in Figure 2a or Figure 2c this can also be open below so as to further reduce the installed height of the housing 50 and thus of the entire latching device. At the same level as the catch depression 62 there are recesses 66 in the side steps 57 of the housing block 50; these accommodate the guide pin 34 when it is pivoted.
Figure la and Figure 2a show the latch hook 30 in the closed position, whereas Figure lb indicates the opening movement of the actuating bar lock 10. The actuating bar 12 slides downward between the lower side of the cover plate 20 and the upper side 59 of the housing block 50. In so doing, it moves the latch hook 30 that is installed in the transverse slot 14 with it and slides it in the opening direction within the elongated slot 22 in the cover plate 20. The hook blade 37 moves out of engagement with the lock plate; the straight lower edge 31 of the latching element 30 slides on the base surface 58 of the elongated depression 54 of the housing block 50 that is parallel to the cover plate, so that the hook 30 retains its original position, i.e., there is still no rotation of the hook 30 (see Figure lb). The guide pin 34 that slides along beneath the cover plate 20 prevents any unintentional lifting of the latch 30 during this linear movement.
Once the rounded, rear and 44 of the latch reaches the entry slope 56, it is compelled to slide along this until the lower edge 31 of the latching element 30 comes to rest flat against the entry slope 58. This means that the latch 30 is automatically pivoted about its pivot pin 32. The hook blade 37 disappears behind the cover plate 20. The guide pins 34 retract into the symmetrical depressions 66 in the side steps, whereas the hook catch 38 drops into the recess 62 in the base surface 56 of the elongated depression 54. There is a further depression 66 for the hook blade 37 above the depression 62 for the hook catch 38, so that the latching element 30 pivots through the cover plate 20 and the actuating bar 12 pivots almost completely into a hook bed. As can be seen from Figure lc and Figure 2c, in this end position, the rear edge 42 of the latch 40 is almost flush with the cover plate 20. The back surface 40 of the hook catch 38 is flush with the outer back surface 60 of the housing block 50 (Figure 2).
l0 If one moves the actuating bar 12 in the opposite direction, i.e., in the closing direction, the hook catch 38 of the latching element 30 moves onto the similarly inclined upper inclined surface 64 of the depression 62. The catch back 40 slides along the inclined surface 64 in the direction of the cover plate 20, so that the latch 30 is once again pivoted about its pivot pin 32 until the guide pins 34 come to rest against the cover plate 20. The hook blade 37 is completely extended and now slides once again parallel to the cover plate 20 into its lock position.
In order to improve the manner in which the hook 30 is guided, and in order to enhance the reliability of the closed position even further, the steps 57 that are formed on both sides of the elongated depression 54 in the housing block 50 are configured like terraces. As can be seen in Figure 2a, in the lower area of the housing block 50, the steps 57 first run beneath the upper side 59. At the level of the depression 67, the steps 57 run over a slightly inclined surface 61 into the upper side 59. In this way, as they approach the closed position, the guide pins 34 are raised slightly so that--together with the pivot pin 52--they rest directly against the underside of the cover plate 20. In contrast to this, the pivot pin 32 comes to rest just in front of the inclined surface 61, and so does not get raised.
Should it be necessary, a plurality of latching devices of this kind can be arranged along the actuating bar 12 or the cover plate 20. This will depend on the number of places at which a door is to be latched.
The manner in which the latch device according to the present invention operates is shown diagrammatically in Figure 2a to Figure 2c. Figure 2a shows the hook 30 extended longitudinally and transversely, as it would be when the sliding door is closed and it is in engagement with the lock plate. When the latch is open, the hook 30 is moved by the actuating bar 12 as it moves longitudinally; the actuating bar 12 is covered by the cover plate 20 that is screwed to the rabbeted stile of the door. The hook 30 is raised and lowered perpendicularly to the movement of a actuating bar by sliding edges 31, 40, 44 on the underside, front and back of the hooks and corresponding entry slopes 58, 64 in the hook bed, the cross-section of which is matched to the cover slot 22. The entry slopes 58, 64 together with the rounded hook end 44 and the hook catch 38, 40 thus form control elements that determine the functional movement of the hook. The latching element 30 can also be in the form of a two-arm lever that is supported so as to be able to pivot about the pivot pin 32. The first lever arm forms the hook blade 37, whereas the second shorter lever arm is formed by the back corner 44. The latter serves as the release element for retracting the latch 30.
If the actuating bar 12 is moved longitudinally in order to open the door, the hook 30 is first disengaged from the lock plate over two-thirds of the travel of the actuating bar as in Figure lb, like a conventional and non-retracted hook during a purely longitudinal movement, before it is moved through the cover plate 20 and the actuating bar 12 into the bed of the housing block 50 during the last third of the actuating bar travel, as is shown in Figure 1 c to Figure 2c, respectively. In this end position, the rear edge 42 of the hook 30 is almost completely flush with the cover plate 20.
In another embodiment, in addition to the latching devices described above, the actuating bar lock 10 has an additional restraining and release mechanism 100. This serves to restrain the actuating bar 12 in the unlatched position of the latching element 30 and, once the door has been closed, to release it automatically in order that the latching elements 30, which are spring-loaded in the closing direction, can return to their latched positions automatically. To this end, within the actuating bar drive system (not shown herein), there is a compression spring that is pretensioned when the handle (not shown herein) is operated. As soon as the latching elements 30 have reached their retracted end positions and the spring has been pretensioned to the maximum extent possible, the actuating bar 12 is fixed in its position by the restraining and release device. The rotary handle (not shown herein) then free-wheels back to its starting position.
The restraining and release device 100 that is shown in Figure 3a to Figure 3c is arranged along the actuating bar 12 above a latching device. It has a detent element 130 that is positively coupled to the actuating bar 12 and is in the form of a two-arm lever. When the latching element 30 reaches a specific position, a first lever arm 132 passes through the actuating bar 12 and the cover plate 20 in the longitudinal direction, whereas a second shorter lever arm 134 fits into a corresponding detent depression 158 in the bottom 155 of a housing block 150. The actuating bar 12 and the cover plate 20 incorporate elongated slots 135 or 140, respectively, to allow passage of the lever 130, and the widths of these elongated slots corresponds to the thickness of the lever 130.
The lever 130 that is of square or rectangular cross section is supported beneath the cover plate 20 in the housing block 150 so as to be displaceable in the longitudinal direction (Figure 3a). The latter has an elongated body 152 that is secured to the cover plate 20, preferably by screws. The cams 153 pass through the actuating bar 12 that extends between the housing 2~ block 150 and the cover plate 20, and which is freely displaceable; to this end, the longitudinal elongated slot 135 of the actuating bar 12 is provided with widened sections 138 in each operating direction. The width of the housing block 150 is about the same as the width of the actuating bar 12, so that there is a minimal requirement for space. The overall length of the elongated slots 135-in the actuating bar 12 and the length of the housing block 150 or the space between the guide cams 153 is such that there can always be sufficient longitudinal displacement of the actuating bar 12. A flat elongated recess 154 is provided within the housing block 150 to accommodate and guide the lever 130, and the lever 130 is installed flat in this. For reasons of assembly, the entire housing block 150 is formed so as to be symmetrical with reference to its longitudinal centre. Thus it can be secured to the cover plate 20 in any direction. The elongated slot 140 of the cover plate 20 is flush above the lower half of the long elongated recess 154. Its width is matched to the width of the lever or of the elongated recess 135 of the actuating bar 12.
The lever 130 is coupled to the actuating bar 12 through a transverse pin 142 that, as a pivot body, is installed in the lever 130 from the side or is made in one piece with this.
As can be seen in Figure 3b, the pin 142 is located between the first, longer lever arm 132 and the second, shorter lever arm 134; it is expedient that these be made in one piece. As shown in Figure 3b, the pin 142 is shape mated to, and fits in, a transverse groove 136 in the elongated slot 135 in the actuating bar and lies with its pin ends that project to the side on two elongated steps 157 that are formed on both sides of the elongated recess 154 in the housing block 150. From the other side, the pin 142 is protected by the cover plate 20 that lies over the actuating bar 12.
In the closed-position, the lever 130 lies flat on the bottom 155 of the elongated recess 154 of the block 150, 152, while the pivot pins 142 rest on the side steps 157. The second, shorter lever arm 134 lies in the closing direction, and the second, longer lever arm 132 lies opposite the closing direction in the housing block 150. As soon as the actuating bar 12 is moved by means of the actuating bar drive system, the pin 142 is engaged by the transverse groove 136; the lever 130 tracks every movement of the actuating bar 12 directly within the housing 150, the pivot pin ends sliding between the cover plate 20 and the housing steps 157.
The detent depression 158 for the lever arm 134 is provided in the precise centre of the housing block 150. This is a prism-shaped depression that is made in the bottom 155 of the elongated recess 154. The length of the elongated recess 154 is approximately twice as large as the overall length of the lever 130. A leaf spring 170 is arranged between this and the cover plate 20 within the upper widened section 138 in the elongated slot of the actuating bar 12. This spring is installed with an offset end 172 in a clamping slot 174 in the housing block 150.
Its unattached end 175 is exactly over the upper half of the prism-shaped depression 158 on the lever 138. Thus, it is constantly acted upon by a spring force in the direction of the housing bottom 155 through the depression 158.
When the latching element 30 is in its closed position, the lever 130 first lies flat beneath the cover plate 20 in the elongated reasons 154 of the housing block 150 (Figure 3a). The unattached, slightly offset end 175 of the leaf spring 170 lies on the long lever arm 130.
If the latching element 30 is actuated by means of the handle, the actuating bar 12 slides downward between the cover plate 20 and the housing block 150. In so doing, it takes the lever 130 that is installed in the transverse slot 136 with it and moves it within the elongated depression 154 downward in the opening direction. Just before the latching elements 30 reach the final open position, the pivot pin 142 of the lever 130 passes the contact point of the leaf spring 170. As soon as this moves behind the pivot pin 142, the spring 170 acts on the shorter lever arm 134 that is following behind the longer lever arm 132.
Since, because of its shorter dimensions, this is now, like the unattached end 175 of the leaf spring 170, above the detent depression 158, it is pushed downwards and into the depression 158 by the spring 170, and held their (see Figure 3c). In order to achieve a more reliable detent, the end of the lever 304 is inclined slightly corresponding to the opening angle for the shape of the prism-shaped depression 158, so that the end of the lever hooks into the detent depression 158 and the actuating bar is restrained firmly in the position that it has reached against the actuating bar return spring. At the same time as the short lever arm 134 engages in the detent depression 158, the first, longer lever arm 132 passes to the outside through the openings 135, 140 of the actuating bar 12 and the cover plate 20. Because of the permanent spring-loading of the short shorter lever arm 134, the exposed lever 132 will be held in this position. The latching element 30 are in their retracted position; the door can be opened without any potentially dangerous latching hooks projecting from the outside side surface of the door stile.
If one closes the door, then the rabbeted side surface of the door stile moves against the corresponding face of the door frame. The lever arm 132 that is projecting from the cover plate 20 now serves as a release. It is pivoted inward about the pivot pin 142, so that the end of the second lever arm 134 is raised out of the prism-shaped depression 158 in the housing bottom 155. The detent is released; the actuating bar 12 can once again slide freely in the closing direction. The latching element 30 that are attached to the actuating bar 12 are moved into their detent positions by the return force that is stored in the actuating bar drive system. On closing, the door is automatically latched. The amount of force required to release the detent can be so adjusted by suitable selection of the ratio of the lengths of the lever arms 132 and 134 that the restraining and release device 100 does not hinder the closing of the door although, at the same time, unintentional release of the detent is effectively prevented.
Yet another embodiment of the present invention, shown in Figure 5, permits simple shipping and simple and rapid assembly of the actuating bar lock 10.
It is frequently useful to manufacture actuating bar 12 and cover plate 20 divided into a number of sections. The parts, disassembled for shipping, are then assembled on site and installed. Whereas the sections of the cover plate require no connection to each other since they are screwed rigidly into the rabbeted groove, the sections of the activating are must be secured rigidly to each other in order that they can slide freely within the door groove.
The coupling shoe 200 that is required to connect the sections of actuating bar, shown in Figure 5, incorporates an elongated and essentially rectangular base body 202. On the underside of the base body 202 are four round pins 204 that are aligned; these are inserted into the base body to or made in one piece with it. On the opposite side, the base body is rounded over at the ends 206 in the longitudinal direction.
During assembly of the actuating bar lock 10, two pins 204 of the coupling shoe 200 are inserted into corresponding recesses 208 in the particular actuating bar end 207; these are pressed into the bores 208 so as to form a friction fit. This ensures a permanently secure connection whereas the arrangement of the pins 104 in a line ensures precise orientation of the coupling shoe 200 and the actuating bar 12. Since the base body 202 of the coupling shoe 200 is enclosed on all sides by the door, it cannot fall out of the bores 208 even after a long period of use. The rounded ends 206 ensure permanently easy longitudinal movement within the door groove. In addition to ease of operation and assembly, as well as reliable operation, the coupling piece 200 entails an additional but important advantage.
The actuating bar lock 10 can be used unmodified at any time without operating bar extensions, i.e., with only the permanently installed central plate since, in contrast to the prior art, the ends of the lock side actuating bar are in each instance covered by the cover plate.
The present invention is not confined to the embodiment described heretofore, but can be modified in a number of ways.
For example, the housing blocks 50, 150 as well as the latching device and the restraining device can be made in one piece. They can also be assembled from two symmetrical housing halves that are provided with the appropriate symmetrical and mirror image recesses and bolted securely to each other.
All of the features and advantages, including design details, spatial arrangements, and process steps set out in the claims, the disclosure, and the drawings are essential to the present invention, both singly and in the most varied combinations.
