US 20070085354 A1Abstract
The present invention relates to a door opener system having a door opener, which comprises a pivot latch pivotable into the door opener having a stop, having a striker plate, and having a lock latch guide running diagonally inward into the door opener for guiding the lock latch, an adapter part being provided, on which the lock latch guide is implemented and which is situated between the door opener and the striker plate. In order to obtain a flexibly usable and simultaneously reliably functioning door opener system, the lock latch guide is implemented as a slide face, which runs continuously over the stop width and is situated on the door side next to the stop of the pivot latch and adjoining thereto. Images(11) Claims(14)
In the various embodiments described in the following, identical components in the figures are provided with identical reference numerals. FIG. 1 shows a perspective exploded view of a door opener system 10. FIG. 7 also shows a perspective view of the same door opener system 10 in the assembled state. The door opener system 10 is constructed modularly and comprises a flat striker plate 11, an adapter part 12, and a door opener 13. The adapter part 12 is situated between the door opener 13 and the striker plate 11. In all three components cited of the door opener system 10, two screw holes 14 are provided, which lie one on top of another in the assembled state of the door opener system, so that screws 15 may be inserted therein to connect the individual components of the door opener system 10 to one another solidly. The striker plate 11 comprises a latch opening 16, through which a lock latch (see FIGS. 4 and 5 as well as 9 through 11) may engage in the door opener latch 17, which is pivotable inward into the door opener 13. The latch opening 16, viewed in the striker plate plane, is enclosed on all sides by the striker plate 11. A rectangular bolt opening 18 is provided in the longitudinal direction of the striker plate 11 in each case above and below the latch opening 16, through which a door bolt or a similar part may engage in the door opener system 10. The bolt openings 18 are implemented and situated symmetrically to one another, so that the striker plate 11 or the entire door opener system 10 may be mounted both on the left and also the right of the frame. The door opener 13 comprises a pivot latch 17, on which a stop 19 is implemented. The stop 19 projects upward on the door-side side of the door opener 13 from the pivot latch 17 and runs over the entire width of the pivot latch 17. In addition, the stop 19 is implemented continuously, i.e., without recesses, openings, or similar features. The adapter part 12 may be placed on the door opener 13 and is mounted thereon. The basic shape of the adapter part 12 is based on an approximately rectangular frame, in whose middle an also approximately rectangular opening 121 is provided, which essentially corresponds to the dimensions of the pivot latch 17. The adapter part 12 is implemented to rest on the door opener 13 in such a way that the bottom side of the adapter part 12 rests flush on the door opener 13 and the pivot latch 17 may pivot freely and is free for a lock latch to engage. A trough 122, which extends in the longitudinal direction of the adapter part 12 from one side to the other end, projects slightly on each side from the adapter part 12 at the outer edge of the narrow sides of the adapter part 12, is implemented on the door-side area of the adapter part 12, which presses against the stop 19 of the pivot latch 17 from the outside in the installed state. On the top, the trough 122 terminates flush with the adapter part 12 and projects downward therefrom. A web 123, which is also continuous over the entire length of the adapter part 12, is implemented projecting from the trough 122 on the door-side outer edge of the adapter part 12. This web 123 projects slightly beyond the adapter part 12 on top and forms the terminus of the adapter part 12 on its door-side edge. The lock latch guide 20 is provided on the interior of the web 123 and the trough 122, which is implemented as a slanted plane running diagonally inward to the opening 121 (see FIGS. 3 through 5). The length of the lock latch guide 20 essentially corresponds to the length of the opening 121 and thus also the length of the pivot latch 17 as well as the stop 19. It runs from the uppermost point of the web 123 to the lowermost point of the trough 122. The trough 122 has a bevel toward only one side in the area of the opening 121, which forms a part of the lock latch guide 20, i.e., it is open toward the opening 121. In contrast, in its end areas, i.e., in those areas of the trough 122 which project beyond the opening 121 of the adapter part 12 and the longitudinal direction, the trough 122 has a diagonal plane on two sides. One slanted plane is an extension of the lock latch guide 20 and accordingly runs from top to bottom in the direction of the opening 121. A further diagonal plane, which leads out of the trough 122, is opposite this diagonal plane (see FIGS. 3, 12, and 13). These areas of the trough 122 each form a blocking latch guide 21. The blocking latch guides 21 thus each adjoin one end of the lock latch guide 20, viewed in the longitudinal direction. Normally, in known door locks having a blocking latch function, only one blocking latch is provided in addition to a lock latch (see FIGS. 9 through 11). Therefore, normally only one of the blocking latch guides 21 is required for guiding a blocking latch. The implementation of two blocking latch guides 21 at each end of the lock latch 20 has the advantage, however, that the adapter part 20 or the entire door opener system 10 may be installed both on the left and also the right of the frame. FIG. 2 shows a perspective exploded view of a further embodiment of a door opener system 10, which is similar to that from FIG. 1. The same embodiment is shown in the assembled state in FIG. 8. The difference to the embodiment from FIG. 1 is that the striker plate 11′ is implemented as an angled striker plate. Therefore, a web 112′ extends essentially perpendicularly from the flat upper part 111′ downward at the door-side edge. The web 112′ is narrower in the area of the latch opening 16 than in its remaining area. The lower edge of the web 112′ is implemented as continuous and linear over the entire length. The distance between the narrowed web area 113′ and the upper part 111′ approximately corresponds to the level of the web 123 projecting on the door side from the adapter part 12. This web 123 is thus implemented so that it rests on the narrower web part 113′ of the striker plate 11′ in the installed state and terminates essentially flush with the surface of the upper part 111′ of the striker plate 11′ (see FIG. 8). A visually closed implementation of the angled striker plate 11′ thus results. FIG. 3 shows a perspective view of a partial area of a door opener system 10 having an angled striker plate 11′. The adapter part 12 is introduced into the striker plate 11′, the web 123 of the adapter part 12 resting on the narrow area 113′ of the web 112′ of the angled plate 11′. The adapter part 12 is situated so that it terminates flush with the web 112′. A blocking latch guide 21 is recognizable next to the lock latch guide viewed in the longitudinal direction. The door-side bevel 211 of the blocking latch guide 21 is an extension of the lock latch guide 20 in the longitudinal direction of the door opener system. It leads into the door opener system 10 up to a floor area 212 of the blocking latch guide 21. A further slanted plane 213, which is situated diametrically opposite the first slanted plane 211, leads back out of the floor area 212 from the door opener system 10, up to the upper edge of the adapter part 12. The second blocking latch guide at the other end of the lock latch guide 20 is implemented symmetrically to the first blocking latch guide 21 (see FIG. 2). FIGS. 4 and 5 each show a cross-sectional view of the same door opener system 10. In both door opener systems 10, a lock latch 21 of a door 23 engages in the door system 10. The pivot latch 17 is located in each case in the pivoted state, i.e., it is pivoted into the interior of the door opener 13 around the pivot axis 24. The lock latch 22 retained by the pivot latch 17 is thus released and the door 23 is now freely pivotable and may be opened. During the opening procedure, the lock latch 22 stops in the area of its tip 221 at the lower end of the lock latch guide 20 and slides along it in the further course of the opening procedure. It is pressed against a spring force into the interior of the door 23 (see FIG. 5). After reaching the upper point of the lock latch guide 20, it slides over the surface of the door-side web of the striker plate 11 until it finally leaves the door opener system entirely and is again pressed by the spring force out of the door 23. The adapter part 12, including the lock latch guide 20 from FIGS. 4 and 5, is similar to that shown in FIGS. 1 through 3. In contrast thereto, a web 124, which projects perpendicularly downward, adjoins the trough 122. The web 124 is drawn downward far enough that it overlaps an area 132 of the door opener cover 131 projecting diagonally outward. The area 132 projects diagonally outward in order to provide the pivot latch 17 with enough space to pivot. The lock latch guide 20 is implemented as a continuous slanted plane which extends over both the interior of the web 123 and also the interior of the trough 122. The upper area of the web 123 is situated so that it terminates flush with the surface of the striker plate 11. FIG. 6 shows a perspective view of the front, lower area of a door opener system 10. An area 132, which approximately corresponds to the width of the pivot latch 17 and covers the lower area of the pivot latch 17, projects outward and diagonally upward from the door opener cover 131. This area 132 is implemented as an apron. The upper area of the pivot latch 17 or its stop 19 is covered by the trough 122 or by the web 123 of the adapter part 12. A middle area of the pivot latch 17 is uncovered to the outside. A closed system of the door opener system thus results overall, so that no dirt, dust, or similar material may enter in the door opener system 10 from the sides or from below. Even if the pivot latch 17 was pivoted completely into the door opener 13, the trough 122 is implemented as drawn downward far enough that the upper area of the stop 19 is still within the trough 122, so that a closed system is ensured at all times. This closed implementation is also visually desirable. FIGS. 9 through 11 show perspective views of a door opener system working together with a door lock 25. The door opener system 10 in FIGS. 9 and 10 is provided with a flat striker plate 11, in contrast, the door opener system 10 in FIG. 11 is provided with an angled striker plate 11′. The lock 25 is a �Scandinavian lock� having a total of three latches. The right latch is a lock latch 22, which is implemented to engage in the door opener 13. Neighboring it on the left, a narrower blocking latch 26 is provided, which is implemented to block the lock latch 22 when the lock latch 22 is pivoted completely into the door opener 13 and engages behind the stop of the pivot latch. Neighboring the blocking latch 26 on the left, a further latch 27 is implemented, which assumes the bolt function for the door lock 25 and is implemented to engage in a bolt opening 18 provided in the striker plates 11, 11′. The illustration in FIG. 9 shows the lock 25 shortly before entering the door opener system 10. The blocking latch 26 locks the lock latch as soon as the blocking latch 26 is pressed completely against a spring force into the lock 25 up to a switching point. The blocking latch 26 is situated somewhat recessed in relation to the lock latch 22 in the movement direction of the lock 25, so that the lock latch 22 is not yet locked by the blocking latch 26 during the insertion procedure. In the illustration in FIG. 10, the door lock is shown shortly before reaching its final position, i.e., the lock latch 22 presses against the upper area of the stop 19 from the outside. The blocking latch 26 presses against the upper area of the diagonal plane 213 of the blocking latch guide 21. The latch 27 is also shown shortly before engaging in the bolt opening 18. In the illustration shown in FIG. 11, the lock 25 is in its final position, i.e., the lock 25 is locked. The lock latch 22 engages behind the stop 19 and the latch 27 engages in the bolt opening 18. The blocking latch 27 is seated on a contact surface 114′ of the striker plate 11′ and is pressed far enough into the door lock 25 that the switching point is reached and the blocking latch 26 blocks the lock latch 22. The lock latch 22 may thus be displaced no further against the spring force of the lock 25, not even by attempts at manipulation from the outside. FIG. 12 shows a perspective sectional illustration of a door opener system 10 having a flat striker plate 11 in the locked state. The blocking latch 26 rests on the contact surface 114 of the striker plate 11 and locks the lock latch 22. FIGS. 13 and 14 show further perspective sectional illustrations of a door opener system 10 having a flat striker plate 11, which is in the released state. In the illustration shown in FIG. 13, the blocking latch 26 is extended completely and is located inside the area delimited by the V-shaped blocking latch guide 21, but does not press against it. The lock latch 22 is situated offset forward in the opening direction in relation to the blocking latch 26 and thus already presses against the lock latch guide 20 and is pushed thereby into the interior of the door lock 25. This offset arrangement of blocking latch 26 and lock latch 22 avoids having the lock latch 22 be blocked by the blocking latch 26 upon opening until it is extended far enough that it may slide out of the door opener system 10 over the striker plate 11. In the illustration from FIG. 14, the tip of the blocking latch 26 presses against the diagonal slide bevel 211 of the blocking latch guide 21. The lock latch 22 is retracted further into the door lock 25 than in the illustration from FIG. 13.
