Abstract

The invention relates to a fitting for a lock which exhibits a latch, a dead bolt, a latch socket (2) and a dead-bolt socket (4). The fitting contains a handle (10), which interacts with a latch-actuating member (8) projecting through the latch socket (2), and a dead-bolt-actuating member (9) projecting through the dead-bolt socket (4). The fitting further exhibits a transmission mechanism which connects the dead-bolt-actuating member (9) and the handle (10) and is designed such that the opening and closure movements, both for the latch and for the dead bolt, can be effected by one and the same handle (10). <IMAGE>

Description

  • The invention relates to a fitting of the type specified in the preamble of claim 1.
  • Locks with separate latches and bolts are mainly attached to the doors of bathrooms, toilets, changing rooms or the like. The fittings previously known for such locks have a handle on the inside of the door, e.g. a door handle to operate the latch and a second handle, e.g. an olive to open the latch. Both handles can be coupled via an actuator that protrudes through a latch or bolt nut of the lock, usually a conventional square mandrel, with a fitting provided on the outside of the door, which also has a handle for the latch, but in the area of the bolt actuator with a free / occupied Display and possibly provided with an emergency opening device.
  • The need to close or open the door from the inside by means of two different functional sequences causes problems especially for children, the elderly, the disabled or the like. These result from the fact that, on the one hand, the function of the latch olives is not always clearly understandable for the group of people mentioned and, on the other hand, that many latch olives cannot be clearly recognized whether the latch is in the closed or open position.
  • The invention is therefore based on the object to remedy this situation and to design the fitting described at the outset in such a way that a simplified latch actuation and a more secure free / busy display are possible.
  • The characteristic features of claim 1 serve to solve this problem.
  • The invention has the advantage that, despite the use of conventional locks, it enables latch and bolt actuation with only one handle. It is therefore only necessary to replace the fitting if necessary. This is generally not a problem because the distances between the latch and bolt actuators have been standardized for a long time and therefore only a single fitting size adapted to this distance needs to be provided.
  • Otherwise, the transmission ratio within the fitting according to the invention is preferably selected so that the locking position of the bolt results after the handle has been rotated by approximately 30 °. As a result, when using conventional door handles in the closed position of the bolt, a striking handle position is achieved which is also easily recognizable by the group of people mentioned at the beginning. Finally, there is the advantage that pressing the door handle down, like in a panic lock, opens both the latch and the bolt, so that a simple lock actuation is possible even in emergencies.
  • Further advantageous features of the invention emerge from the subclaims.
  • The invention is explained in more detail below in connection with the accompanying drawing using exemplary embodiments. Show it:

  • Fig. 1 shows a well-known lock, which is preferably used on doors of rooms that should be lockable from the inside. For this purpose, the lock contains a lock case 1, in which a latch nut 2 for a latch 3 and a latch nut 4 for a latch 5 are rotatably mounted. The lock is usually stored in a lock pocket 6 of a door 7 or the like according to FIG. 2 and fastened to the inside edge of the door with a face plate 1a (FIG. 1), while the latch 3 and the bolt 5 can be seen in FIG. 1 The closed position protrude into recesses which are formed in a frame or the like carrying the door 7 or the like. From the closed position, the latch 3 and the bolt 5 can be retracted into a fully recessed position in the lock case 1 by rotating the latch nut 2 or the latch nut 4. Here means e.g. looking at Fig. 1, a clockwise rotation a rotation in the opening direction and a counterclockwise rotation a rotation in the closing direction. The rotation is usually carried out by means of a latch actuator 8 or a latch actuator 9, both of which preferably consist of conventional square profiles and protrude through a corresponding cross-section recess in the latch or latch nut 2 or 4, and a pair of handles 10 and 11 which can be coupled on both sides of the door 7 (Fig. 2) with the actuators 8.9. In Fig. 2 the handle 10 is arranged on the inside of the door 7 and the handle 11 on the outside of the door 7.
  • Lock structures and fittings of the type described are generally known and therefore do not need to be explained in more detail.
  • The fitting for the outside of the door, shown schematically in FIG. 2, is designed in a generally known manner and is provided with a lower part 12 in which a neck section 14 of the handle 11 pushed onto the latch actuating element 8 is rotatably mounted and which is covered by a cover cap 15. In contrast, the end of the bolt actuating member 9 located on the outside of the door projects e.g. in a known manner in a viewing plate 16 of a free / busy display, which makes the respective position of the bolt 5 (FIG. 1) or the bolt nut 4 recognizable from the outside and is usually provided with a means for attaching an emergency opening tool.
  • A fitting according to the invention is attached to the inside of the door 7. This points a lower part 18, which is fastened to the door 7, for example by means of sleeve screws 19 which are screwed into the lower part 12. The lower part 18 is cap-shaped and provided with a peripheral edge 20 which is supported on the door 7 or the like, so that a cavity 21 is formed. In this, an inner part 22 is arranged, which for example essentially consists of a plane-parallel plate and, if necessary, additionally or alternatively, can be fixed to the door 7 with wood screws 23 projecting through the lower part 18.
  • The handle 10, which is preferably made of plastic, like the handle 11, preferably has a metal insert 24 at its mounting end, which protrudes with a projecting, cylindrical neck section 25 into a control nut 26 and is supported by an inclined, e.g. made of steel pin 27 is rotatably connected to this. The control nut 26 serves in a manner to be described, on the one hand, to act on the latch actuating element 8 and, on the other hand, to control a transmission nut 28, which in turn is coupled to the bolt actuating element 9. Otherwise, the lower part 18 can be covered analogously to the lower part 12 by means of a cover cap 29.
  • 3 and 4 show, the lower part 18, in addition to bores 31 for the sleeve screws 19 and / or wood screws 23, has a circular bearing bore 32 for the rotatable mounting of the neck section 25 and undercuts 33 formed in the rim 20, with corresponding undercuts 33 on the cover cap 29 attached undercuts form snap connections that hold the cap 29 on the lower part 18.
  • 5 to 7, the inner part 22 has an outer contour which preferably substantially corresponds to the inner contour of the edge 20 of the lower part 18, so that it is arranged largely immovably in the lower part 18. The thickness of the inner part 22 corresponds essentially to the height of the edge 20. Furthermore, the inner part 22 is provided with bores 34 for the screws 19, 23 and with a cylindrical bearing bore 36 intended for mounting the control nut 26, which radially towards the rear 5 extends at the top, the upper limit of which is indicated in FIG. 5 by a dashed line 38 and which forms a step 39, the bottom of which is arranged lower than the front of the inner part 22. At the same level, guide surfaces 40 bordering the side walls are arranged, the inner boundaries of which are shown in FIG 5 are indicated by dashed lines 41. Otherwise, the guide surfaces 40 expediently extend up to step 39.
  • The inner part 22 also has a stepped bore 42 which has a large diameter on the front side and a small diameter on the rear side and is also provided there with a radial extension 43 (FIG. 5) which is delimited in the circumferential direction by stops 44. Finally, the inner part 22 can be provided on its outer contour with undercuts 45 (FIG. 6) which, when the inner part 22 is inserted into the lower part 18, have undercuts 46 (FIG. 4) which project inwards on its edge 20 and form undercuts Snap connections can interact that hold the inner part 22 captively in the lower part 18.
  • Details of the transmission nut 28 (FIG. 2) result from FIGS. 8 to 10. Thereafter, the transmission nut 28 essentially consists of a circular disk 49 with a diameter corresponding to the larger diameter of the bore 42 of the inner part 22. In the disc 49 protruding driver pins 50 and 51 are inserted above the front. On the rear side, the disk 49 is provided with an essentially cylindrical extension 52, the diameter of which corresponds to the small diameter of the bore 42 and which has a radially projecting arm 53. The thickness of the disc 49 including lug 52 corresponds to the thickness of the inner part 22. In the assembled state (Fig. 2), the transmission nut 28 is inserted into the bore 42 so that the disc in the portion with the large diameter, the lug 52 in the Small diameter section and arm 53 is located in extension 43. The extension 52 and the arm 53 can also protrude beyond the inner part 22 into a corresponding hole in the door 7 (FIG. 2).
  • The transmission nut 28 also has a center hole 54 (FIGS. 8, 10) for the non-rotatable mounting of the bolt actuating member 9. In the exemplary embodiment, the center hole 54 has a square cross section, which corresponds to the reduced cross section of a front end 55 (FIG. 2) of the bolt actuating member 9.
  • 11 and 12, the control nut 26 contains a cylindrical bushing on its rear side 57, on the front of which a disk-shaped, approximately semicircular control cam 58 is formed, the radius of which is larger than that of the bushing 57. The diameter of the bushing 57 corresponds essentially to the diameter of the cylindrical part of the bearing bore 36 of the inner part 22. In the assembled state, the bushing 57 is inserted into the bearing bore 36 from the front until the cam 58 flies to its step 39 and in its extension 37 is arranged. Front ends of the control cam 58 serve as control cams 59 and 60.
  • The control nut 26 also has in its rear part a receiving opening 61 for the latch actuating element 8 (FIG. 2) in such a way that it can be rotated back and forth to a limited extent in the receiving opening 61. In the front part of the steering nut, however, is provided with a center hole 61a for receiving the neck 25 (FIG. 2) of the handle 10.
  • According to Fig. 12, the receiving opening 61 when using a latch actuator 8 with a square cross-section, i.e. a conventional square mandrel, for example delimited by four walls 62 running along cylindrical surfaces, the radius of which, measured from the central axis of the receiving opening 61, is substantially equal to half the diagonal through the cross section of the latch actuating element 8. These walls 62 are evenly spaced in the circumferential direction, for example each extend over approximately 60 ° and are delimited at both ends by flat, somewhat inwardly projecting stop surfaces 63 and 64, respectively. The extensions of the two stop surfaces 63, 64 of each wall 62 each close an angle of a preselected size, e.g. of approx. 30 °. As a result, the latch actuator 8 can be rotated clockwise by approximately 60 ° from a position in which it lies against the stop surfaces 63 into a position in which it lies against the stop surfaces 64. Conversely, the control nut 26 can be rotated counterclockwise relative to the latch actuating element 8 from a position in which the latch actuating element 8 lies against the stop surfaces 63.
  • FIG. 13 shows the latch actuating element 8. It has a continuously square cross section and, according to FIG. 2, projects through the latch nut 2, a corresponding passage in the handle 11 arranged on the outside of the door and the receiving opening 61. Preferably, but not necessarily, the end of the latch actuating member 8 projecting through the receiving opening 61 has a bore 65 with an internal thread, into which an extension 66 with a corresponding external thread can be screwed, which is formed on the front of an insert 67 which follows Fig. 2 in a receiving opening of the handle 10 arranged on the inside of the door rotatably and for this purpose, for example, is also penetrated by the pin 27 and together with the neck 25 of the control nut 26 projects into the center hole 61a. This makes it possible to mount the latch actuating element 8 in a rotatable but nevertheless axially essentially non-displaceable manner, since the relative rotation tolerated by the receiving opening 61 of the control nut 26 in the assembled state by a fraction of a thread of the parts 65, 66 does not cause any significant axial displacement. The handle 11 located on the outside of the door can therefore be fastened to the latch actuating element 8 by means of a transverse pin 68 (FIG. 2) and can thereby be fixed axially relative to the other handle 10.
  • 14 is also preferably designed as a square mandrel and is provided at its front end 55 with the reduced cross-section already mentioned.
  • The control nut 26 and the transmission nut 28 together with two sliders 70, 71 shown in FIGS. 15 to 18 form a transmission mechanism for converting a rotary movement of the handle 10 into a rotary movement of the latch and / or latch nut 2 or 4, as further below is explained.
  • If the lower part 18 and the inner part 22 are designed in accordance with a conventional door plate and the bolt nut 4 is arranged vertically below the latch nut 2 in the assembled state, the bearing bore 36 (FIG. 5) and the bore 42 are at a defined distance from one another. When the control nut 26 and transmission nut 28 are used, the control cams 59, 60 (FIG. 12) and the driver pins 50, 51 (FIG. 8) are also at defined distances from one another. The slides 70, 71 serve for the mechanical coupling of the control cams 59, 60 or driver pins 50, 51 in the manner to be described below and therefore have a length adapted to the respective distance. Upper end faces 72, 73 of slide 70, 71 serve to abut control cam 59 or 60, whereas the lower edges of laterally projecting feet 74, 75 of the slides 70, 71 serve to abut against the driving pins 50 and 51, respectively. Instead of the slide 71, a slide 76 according to FIG. 19 can also be used, which has a lower part 77 with a foot 78 corresponding to the foot 75 and an upper part 79 with an end surface 80 corresponding to the end face 73. As schematically indicated in FIG. 19, a compression spring 81 can be arranged between the two parts 77, 79, which strives to axially shift the two slide parts 77, 79 in opposite directions.
  • In the assembled state, the slides 70, 71 and 76 rest on the guide surfaces 40 of the inner part 22.
  • To assemble the fitting described (FIG. 2), the neck section 25 is first inserted into the bearing bore 32 of the lower part 18 from the front until the handle end face is supported on the latter. The control nut 26 is then pulled with its receiving opening 61 onto the latch actuator 8 screwed to the insert 67 until its control curve 58 comes to rest on the inside of the lower part 18 and the front end of the insert 67 in the receiving opening 61a. Then the pin 27 is inserted from the rear of the lower part 18 into a corresponding, not shown, oblique bore of the control nut 26 and pushed through this into a coaxially aligned, formed in the handle 10 and / or its insert 67 further bore to connect the handle 10 to the control nut 26 in a rotationally fixed manner. The coaxial alignment of these bores automatically results in the desired or required relative rotational position between the handle 10 and the control nut 26. The unit thus preassembled is now pressed onto the inner part 22 after the transmission nut 28 has been inserted into its bore 42 and after the slides 70, 71 and 76 have been placed on its guide surfaces 40 in such a way that they are arranged between the control cams 59, 60 on the one hand and the driving pins 50, 51 on the other. The fitting thus formed is now fastened to the door 7 by means of the wood screws 23 and / or to the fitting mounted on the outside of the door by means of the sleeve screws 19 projecting through it, only the latch actuating element 8 and the bolt actuating element 9 having to be inserted into the corresponding receiving openings (cf. Fig. 2). It then results in essentially the normal position of the handle 10 shown in FIG. 20. Finally, both handles 10 and 11 are axially fixed, for example by means of the transverse pin 68.
  • The operation of the fitting described with reference to FIGS. 2 to 19 is essentially as follows.
  • After the fitting has been installed, the various parts assume the position relative to one another as shown in FIG. 20. In particular, the latch actuating element 8 bears with its side faces against the stop faces 63 of the receiving opening 61, while the slide 70 rests on the one hand with its end face 72 on the control cam 59 and on the other hand with its foot 74 on the driver pin 50. The latch is under the influence of a conventional lock spring in the closed position. The bolt is withdrawn. Finally, the slide 71 rests with its foot 75 on the driving pin 51, while its upper end face 73 is at a preselected distance from the associated control cam 60.
  • To move the bolt into its closed position, the handle 10 must be moved from the position shown in FIG. 20 through an angle d of e.g. about 30 ° to the position shown in FIG. 21 are pivoted. During this movement, the bushing 57 rotates freely on the latch actuator 8 without influencing it, because the stop surfaces 63 move away from the side surfaces of the latch actuator 8 and the stop surfaces 64 would not rest on these side surfaces until after an angle of rotation of approximately 60 ° . The threaded portions of parts 8 and 67 (Fig. 13) also allow this rotation because the insert 67 is not fully tightened in the bore 65.
  • As a result of the rotary movement of the control nut 26 firmly connected to the handle 10 by approximately 30 °, its control cam 59 presses the slide 70 in FIG. 21 downward against the driving pin 50, as a result of which the transmission nut 28 rotates counterclockwise. The distance of the driving pin 50 from the axis of rotation of the transmission nut 28 is selected so that there is a rotation thereof by approximately 90 °, whereby the bolt nut 4 is rotated by a corresponding amount via the bolt actuating element 9 and the bolt is advanced into its closed position. At the same time, the slide 71 is through 21 so far that its upper end face 73 lies against the control cam 60. The distance traveled by the slide 71 is greater than the distance traveled by the slide 70 in the same rotation of the transmission nut 28, because the driving pin 51, as shown in FIGS. 20 to 22, has a greater distance than the driving pin 50 from the axis of rotation of the transmission nut 28.
  • The position of the handle assumed in the closed position of the bolt (FIG. 21) is clearly recognizable and also widely visible, particularly when a door handle is used. The handle 10 retains this position due to the usual friction conditions even if it is a door handle which exerts a certain torque on the control nut 26.
  • If the handle 10 is rotated from the position according to FIG. 21 by approximately 30 ° back to the position according to FIG. 20, the control nut 26 again performs an idle stroke until its stop surfaces 63 rest against the side surfaces of the latch actuating element 8 without it to influence while at the same time her control cam 60 pushes the slide 71 down. However, the bolt is only partially retracted because, because of the large distance of the driving pin 51 from the axis of rotation of the transmission nut 28, a rotation of the control nut 26 by 30 ° is not sufficient to turn the transmission nut 28 back by 90 °.
  • If the handle 10 is rotated beyond the position according to FIG. 21 into the position according to FIG. 22, for example by an angle β of again approximately 30 °, then the stop surfaces 63 of the receiving opening 61 of the control nut 26 act on the latch actuating element 8. so that this is also rotated by approximately 30 ° and the latch is retracted into its open position. At the same time, the control cam 60 pushes the slide 71 further down until it returns to the position shown in FIG. 20, whereby the bolt is also fully retracted into its open position, ie the door 7 (FIG. 2) can now be opened. If the handle 10 is then released, the lock spring acts on the latch nut 2 and this acts on the latch actuator 8 in the sense of a backward rotation by the angle β. Since at this moment the latch actuating element 8 bears against the stop surfaces 63 (FIG. 22), the control nut 26 and the handle 10 are also in the zero position according to FIG. 20 is turned back so that the latch returns to its closed position. The bolt, on the other hand, remains in its open position because, due to the selected transmission ratio, the slide 70 moves a smaller distance than the slide 71 when the control nut 26 is turned from the position shown in FIG. 21 to the position shown in FIG. 22 and therefore the control cam 59 in the 22 apparent from the upper end face 72 of the slide 70 is lifted. After turning back the handle 10, the starting position according to FIG. 20 is again obtained.
  • Moreover, it goes without saying that the width of the end faces 72.73 or feet 74.75 of the slide 70.71 is selected such that they can interact with the associated control cams 59.60 or driver pins 50.51 in all the positions described.
  • From the position shown in FIG. 20, it is also possible to immediately pivot the handle 10 by the angle β into the position shown in FIG. 22 without the latch being closed beforehand. In this case, the usual latch actuation occurs without influencing the bolt, because the control cam 60 according to FIG. 20 can rotate through the angle β without acting on the driver pin 51.
  • On the outside of the door, the latch can be opened or closed in the usual way by means of the handle 11. The bolt actuating element 8 rotates freely in the receiving opening 61 of the control nut 26 without influencing it, so that the inner handle 10 can at most reach the position shown in FIG. 22 due to its weight. An actuation of the bolt, however, is not possible with the handle 11 because rotation in the opposite direction is blocked by the latch nut. An actuation of the bolt is at best possible from the outside in that the viewing plate 16 is actuated with an emergency opening tool.
  • The radially projecting arm 53 (FIG. 10) can serve in the described function to limit the angle of rotation for the transmission nut 28 to 90 ° by mounting the arm in the extension 43 (FIG. 5) of the bore 42 of the inner part 22 in this way is that it stops at the ends of the rotational movement on the associated stops 44.
  • When dimensioning the distances of the driving pins 50, 51 from the axis of rotation of the transmission nut 28 and the length of the slider 70 and 71, and according to FIGS. 15 to 18 the slider 71 is somewhat longer than the slider 70, the angles of rotation must be taken into account with commercially available locks (Fig. 1) for a full stroke of the latch or bolt 5 are required. Normally, the angle of rotation for the latch 3 is approximately 30 ° or less, the angle of rotation for the latch 5, however, is constantly 90 ° (cf. FIGS. 20 to 22). In order to nevertheless be able to use the same transmission mechanism for all locks, the slide 71 is replaced by the slide 77 according to FIG. 19 according to the previously best-considered embodiment, so that the function according to FIGS. 23 to 25 results.
  • The position according to FIG. 24 corresponds to that according to FIG. 21 with the difference that the two parts 77 and 79 of the slide 76 are held at a certain distance by the compression spring 81, so that they can be displaced axially relative to one another. If the handle 10 is now rotated back by the angle d, the slide parts 77, 79 are first brought into contact with each other under further tension of the compression spring 81, and only then does the transmission nut 28 and the bolt actuating member 9 partially rotate back via the slide 76 and the driving pin 51 (Fig. 23). If the handle 10 is then rotated through the angle in the sense of opening the latch, the control cam 60 first acts directly via the slide 76, i.e. positively on the driving pin 51. If the trap is already after a rotation of e.g. 15 ° fully retracted and then a further rotation of the handle 10 via the latch nut 2 (Fig. 2) blocked, the bolt is still fully retracted. This results from the frictional connection or the effect of the compression spring 81, which now relaxes, thereby pushing apart the two slide parts 77, 79 in the manner shown in FIG. 25 and thereby pushing the slide part 77 downwards so far that its foot 78 acts on the transmission nut 28 via the driving pin 51 until it has completed its rotation by a full 90 °. This sequence of movements is also possible without positive locking because of the favorable leverage and the smooth movement of the bolt in the last part of its movement stroke.
  • The function described with reference to FIGS. 23 to 25 is up to a maximum angle of rotation the latch nut 2 of, for example, 30 ° is possible, in which case the two slide parts 77, 79 remain in mutual contact until the bolt is fully retracted. The maximum angle of rotation can be determined, for example, by the distance of the driving pin 51 from the axis of rotation of the transmission nut 28, which is smaller in the embodiment according to FIGS. 23 to 25 than in the embodiment according to FIGS. 20 to 22.
  • Otherwise, the function of the embodiment according to FIGS. 23 to 25 is analogous to that according to FIGS. 20 to 22, since the handle 10 rotates back by the angle when released and the control cam 59 is placed again on the upper end face 72 of the slide 70 20, which corresponds to the zero position according to FIG. 20 with the difference that the compression spring 81 then presses the upper end face 80 of the slide 76 against the control cam 60 in the same way as applies to the position according to FIG. 23.
  • The invention is not restricted to the exemplary embodiments described, which can be modified in many ways. For example, it is possible to design the transmission mechanism differently from the manner shown, in particular in the event that, for example, the latch and bolt actuators 8, 9 lie next to one another instead of one below the other. Other transmission mechanisms can also prove to be useful if, unlike the narrow door plate shown, there is more space for its accommodation. Furthermore, it is possible to adapt the transmission mechanism to the different rotation angles of the latch nut and / or the bolt nut in a manner other than that described, for example by providing specially manufactured transmission nuts 28 and / or slides 70, 71 for each lock that is commercially available. Furthermore, the invention is not limited to the fact that the handle 10 is pivoted in the closed position of the bolt by an angle of 30 ° with respect to the zero position. Rather, the transmission ratio of the transmission mechanism can also be chosen so that there are smaller or larger swivel angles, a swivel angle of 90 ° also being conceivable. Furthermore, it is possible to rotate the latch actuator 8 by other means, but to connect it axially immovably to the handle 10. Finally, the lower parts 18 and inner parts 22 can be designed in any other suitable shape.
  • Corresponding control nuts 26 are furthermore expediently provided for right and left opening doors. Apart from this, the cross-section of the receiving opening 61 can also have other contours instead of the star or cross shape shown, in particular also be square, but somewhat larger than the cross-sectional area of the latch actuating member 8. Receiving openings of this type are generally known for other purposes (DE 38 33 757 A1, DE 38 33 758 A1).
  • Except for the actuators 8, 9 and the pin 27, the parts of the fitting according to the invention described are preferably predominantly made of plastic by injection molding.
