Description

[0001] The present invention relates to a tool-free assembly with mounting plates, in particular for a handle set for a door.

[0002] State-of-the-art technology includes a handle set - with a first door handle for an inside of a door, - with a second door handle for an outside of the door, - with a square pin that connects the door handles together, - with a first mounting plate associated with the first door handle, - with a second mounting plate assigned to the second door handle, - the mounting plates are connected to each other by screws and - wherein the door handles are arranged to be rotatable about a rotation axis of the mandrel relative to the mounting plates, known.

[0003] With such a door handle set, the two mounting plates are first attached to opposite sides of the door, namely on the inside and one outside. The first mounting plate has two through holes and the second mounting plate has two threaded holes. The screws are screwed through the through holes in the first mounting plate and through holes in the door leaf that are aligned with these through holes in the first mounting plate and the threaded holes in the second mounting plate, into the threaded holes in the second mounting plate. This firmly connects the mounting plates to each other and to the door leaf. A screwdriver or similar tool is required for fastening. Mounting plates are also attached in the same way for door handle sets with a rotating or non-rotating knob as the door handle on one side of the door leaf or with a rotating or non-rotating knob on both sides of the door leaf.

[0004] This is where the present invention comes in.

[0005] The invention is based on the object of proposing an arrangement with a first mounting plate and a second mounting plate, in particular for a door handle set, the mounting plates of which can be mounted on a door leaf without tools.

[0006] This object is achieved according to the invention by an arrangement having the features of claim 1. Accordingly, an arrangement according to the invention has the following features: • a first mounting plate, • a second mounting plate, • at least one pen and • at least one clamping element, • wherein in or on the second mounting plate the at least one pin is fixed, which extends from the second mounting plate to the first mounting plate, • wherein at least one receptacle for a first section of the pin is provided in the first mounting plate, into which the first section of the pin is inserted, • wherein at least one clamping element is provided in the receptacle, which clamps the pin inserted into the receptacle and the first mounting plate together in a releasable manner.

[0007] The first and second mounting plates of an arrangement according to the invention can be connected to each other without the aid of a tool. For this purpose, the pins attached to the second mounting plate are inserted into the receptacles of the first mounting plates and secured there by means of the clamping element. Upon insertion, the clamping element is clamped to the second mounting plate on the one hand and to the pin on the other, so that the pin cannot be easily pulled out of the receptacle.

[0008] Each clamping element, or at least one of the clamping elements, can be a star disk through which the pin inserted into the receptacle extends. Preferably, a star disk is used that has recesses extending alternately from the outer and inner edges of the disk. Shaft-hub connections can be established using such a star disk. In the present case, a connection is established between the pin and the second mounting plate.

[0009] The recesses can be slits and / or triangular. Other shapes are also possible.

[0010] The receptacle in the first mounting plate of an arrangement according to the invention may have a first section whose inner diameter substantially corresponds to the outer diameter of the pin, so that the pin can be moved in this section, for example in order to insert the pin into the receptacle.

[0011] The receptacle in the first mounting plate can have a second section, which, viewed from the direction of the second mounting plate, is arranged behind the first section, whose inner diameter is larger than the inner diameter of the first section and whose inner diameter is substantially equal to or slightly larger than the outer diameter of the star disk. Advantageously, the star disk is arranged in this second section.

[0012] The star washer is advantageously curved and / or tensioned toward the ends of the pins. This allows it to exert a force on the pin that passes through it toward its first end. The star washer then pulls the pin into the recess, preventing it from being pulled out of the receptacle in the second mounting plate. The curvature is aligned against the direction of withdrawal.

[0013] It is possible that the inner diameter of the star washer is smaller than the outer diameter of the pin when the star washer is not mounted or connected to the pin. Once the pin is inserted into the star washer, the star washer expands and rests against the pin under tension. The pin cannot then be easily pulled out of the star washer against its curvature.

[0014] However, it is also possible that the inner diameter of the star washer is larger than the outer diameter of the pin when the star washer is not mounted or connected to the pin. When the pin is then inserted into the star washer, the inner edge of the star washer does not lie against the pin. However, if the inner edge of the star washer is moved against the curvature and the outer edge is simultaneously moved or held in the direction of the curvature, the outer diameter of the star washer expands on the one hand and the inner diameter of the star washer decreases on the other. The same thing happens if the outer edge is moved in the direction of the curvature and the inner edge is held in the opposite direction to the curvature.

[0015] The outer edge of the star washer or the inner edge of the star washer can, for example, be held in place by a shoulder between the first section and the second section of the holder. If the outer edge is held in place by the shoulder, a force can be exerted on the inner edge of the star washer in the opposite direction to the curvature. If the inner edge is held in place by the shoulder, a force can be exerted on the outer edge in the direction of the curvature. In both cases, the outer edge and the inner edge are moved relative to one another. This relative movement causes the star washer to become flatter, the outer diameter to widen and the inner diameter to shrink. This allows the star washer to be clamped to the wall of the holder of the first mounting plate and to the outer surface of the pin.

[0016] It is possible that in at least one or all of the receptacles of the first mounting plate, and in particular in the second sections thereof in which at least one of the star disks is arranged, at least one pressure element is arranged which cooperates with the star disk to clamp the star disk.

[0017] The pressure element can rest against the curvature of the star disk in the area of ​​the inner edge if the star disk is arranged in the holder so that the curvature is aligned against the second mounting plate. Using this pressure element, the inner edge can then be moved against the curvature on the pin. To do this, the pressure element can be pressed towards the first section of the holder. Since the outer edge of the star disk is advantageously held by the shoulder between the first section and the second section of the holder, the outer diameter is widened and the inner diameter is reduced. This causes the star disk to clamp on the one hand against the wall of the second section of the holder and on the other hand against the pin, which is thereby held in the holder and cannot be easily pulled out of the holder.When the pressure element is released, the star disk returns to its original shape, and the clamping between the wall of the second section of the holder and the pin is released. The pin can then be pulled out of the holder.

[0018] The pressure element can rest in the area of ​​the outer edge of the star disk if the star disk is arranged in the holder so that the curvature is aligned towards the second mounting plate. Using this pressure element, the outer edge can then be moved in the direction of the curvature on the pin. To do this, the pressure element can be pressed towards the first section of the holder. Since the inner edge of the star disk is advantageously held by the shoulder between the first section and the second section of the holder, the outer diameter is widened and the inner diameter is reduced. This causes the star disk to clamp on the one hand to the wall of the second section of the holder and on the other hand to clamp on the pin, which is thereby held in the holder and cannot be easily pulled out of the holder.When the pressure element is released, the star disk returns to its original shape, and the clamping between the wall of the second section of the holder and the pin is released. The pin can then be pulled out of the holder.

[0019] It is possible for the receptacle to be a through-hole and for the pressure element to protrude from the receptacle of the first mounting plate, in particular its second section, on the side facing away from the second mounting plate or - when mounted - to be flush with the edge of the through-hole on this side. If the pressure element protrudes from the receptacle of the first mounting plate on the side facing away from the second mounting plate when not mounted, pressure can easily be exerted on the pressure element and thus on the star disk in order to hold a pin inserted into the star disk. If the pressure element protrudes beyond the edge of the second section when not mounted, a force can be exerted particularly easily via the pressure element on the star disk in order to flatten it and increase the outer diameter and reduce the inner diameter.

[0020] An arrangement according to the invention can comprise at least one cover that engages over and covers the first mounting plate. This cover can have an internal thread, and the first mounting plate can have a matching external thread. The cover can be screwed onto the first mounting plate, and a surface of the cover can bear against the pressure element and exert a force on the pressure element in the direction of the second mounting plate.

[0021] The second mounting plate of an arrangement according to the invention can have threaded holes. Second sections of the pins can have an external thread, with which the second sections of the pins are screwed into the threaded holes of the second mounting plate. The screw-in depth allows the length of the pins projecting beyond the second mounting plate to be adjusted in order to adapt the arrangement according to the invention to door leaves of different thicknesses.

[0022] The pins may have constrictions or tapers. These constrictions or tapers can be easily shortened without the use of tools. To do this, a pin can be broken off at such a constriction or taper.

[0023] Further features and advantages of an embodiment of the invention are described below with reference to the drawings.

[0024] It is not necessary for a handle assembly according to the invention to have all of the features described below. It is also possible for a handle assembly or an arrangement according to the invention to have only individual features of the exemplary embodiments described below.

[0025] The handle set shown has • an interior door handle 11, • an outside door handle 12, • a first mounting plate 13 associated with the interior door handle 11, • a first mounting plate 14 associated with the exterior door handle 11, • a square pin 15, which connects the inner door handle 11 and the outer door handle 12, • Pins 16 connecting the first mounting plate 13 and the second mounting plate 14, • a first reset device 17, which is assigned to the inside door handle 11, • a second reset device 18, which is assigned to the outside door handle, • a first cover 19 associated with the interior door handle, • a second cover 20 associated with the exterior door handle, • perforated star discs 21 and • Pressure elements 22. The first mounting plate 13, the second mounting plate 14, the pins 16, the star washers 21 and the pressure elements 22 form the arrangement according to the invention, by means of which the handle set can be attached to a door leaf.

[0026] The door handles 11, 12 of the door handle set are essentially designed in a conventional manner. They have a handle part 111, 121 and a pin part 112, 122 perpendicular to it. Each of the pin parts 112, 122 has one end with a square hole. The ends of the square pin 15 are inserted into these square holes. The ends of the square pin 15 are attached to the door handles 11, 12 in a suitable manner. Various possibilities for this are known to those skilled in the art. The type of attachment is not shown in the figures.

[0027] At the ends of the pin parts 112, 122, these have a shoulder so that the end is slightly recessed toward a first axis, which corresponds to the center axis of the pin parts 112, 122 of the door handles 11, 12. The door handles 111, 112 can be pivoted about this first axis to operate the handle set.

[0028] The first mounting plate 13 has a perforated disc 131 and a wall 132 arranged on one side of the disc 13 and running along the edge of the disc 131. At two opposite points 132, the wall 132 is widened to form domes 133. These protrude inwards and away from the disc 131 beyond the wall. They are thus extended in a direction parallel to the first axis. Through-holes are provided in the domes parallel to the first axis. These through-holes form receptacles in the first mounting plate 13 for the pins 16. These pins have a first section 134 and a second section 135. The first section 134 lies in front of the second section 135 as viewed from the direction of the second mounting plate 14. The first section 134 has a smaller diameter than the second section 135. A shoulder is formed between the two sections 134, 135.

[0029] The ends of the domes 133 projecting beyond the wall 132 are inserted into holes in a door leaf. This allows the first mounting plate 13 to be arranged in a rotationally fixed manner against a torque about the first axis.

[0030] An external thread is provided on the outside of the wall 132.

[0031] The space of the first mounting plate 13 delimited by the perforated disc 131 and the wall 132 forms a receptacle for the first reset device 17.

[0032] The second mounting plate 14 essentially corresponds to the first mounting plate 13. Like the first mounting plate 13, it has a perforated disc, a wall 142 surrounding the edge of the disc 141, domes 143, and an external thread. The second mounting plate 14 can also be inserted into holes in the door leaf with the domes, thereby securing the second mounting plate 14 to the door leaf in a rotationally fixed manner against a torque about the first axis. They differ only in that threaded holes are provided in the domes 143.

[0033] The space of the second mounting plate 14 delimited by the perforated disc and the wall 142 forms a receptacle for the second reset device 18.

[0034] The pins 16 have a first section 161 and a second section 162. Only the second section 162 has an external thread.

[0035] With this external thread, the pins 16 are screwed into the threaded holes in the domes 143 of the second mounting plate. These are guided through holes in the door leaf and inserted into the receptacles in the domes 133 of the first mounting plate 13.

[0036] In the second section 135 of the receptacle of the first mounting plate 13, two star disks 21 are arranged one behind the other.

[0037] The star disks 21 have a hole in the center and, when unloaded, a curvature. The star disks 21 have radial slots that protrude alternately outwards from the inner edge and inwards from the outer edge. The edges of the slots 211 running outwards from the inner edge are parallel, and the edges of the slots 212 running inwards from the outer edge are at an angle to one another, so that they have a triangular shape. The star disks 21 are arranged in the second sections 135 of the receptacle of the first mounting plate 13 such that they are aligned with the curvature in the direction of the first section 134 or the shoulder between the first section 134 and the second section 135. The first star disk 21 in the second section 135, viewed from the direction of the first section 134, rests on the shoulder between the two sections 134, 135. The second star disk 21 rests on the first star disk 21.In the second section, the pressure element 22 is arranged behind the second star disk 21.

[0038] The pressure element 22 is a sleeve or ring which is arranged in the second section 135 and which rests with one end against the second star disk 21 and with another end which protrudes a little from the second section 135.

[0039] The first and second covers 19, 20 are identical. They also have a perforated disc 191, 201 and a rim adjacent to the edge of the disc 191, 201. An internal thread is provided on the inside of the rim 192, 202. The first cover 19 is screwed onto the first mounting plate 13, and the second cover 20 is screwed onto the second mounting plate 14.

[0040] In the fully assembled state of the arrangement comprising the first mounting plate 13, the second mounting plate 14, the pins 16, the star disks 21, and the pressure elements 22, the first cover is screwed onto the first mounting plate in such a way that it presses against the pressure elements 22. The pressure elements 22 transmit this pressure and press on the outer edge of the star disks 21. This tensions the star disks 21. By tensioning the star disks 21, their outer diameter increases and their inner diameter decreases. The star disks 21 are thereby pressed with their outer edge against the wall of the second section 135 of the receptacle in the first mounting plate 13. With their inner edge, however, they are pressed against the pins 16. This creates a firm, but detachable connection between the first mounting plate 12 and the pins 16 by means of the star disks 21. The two mounting plates 13, 14 are thus firmly connected to one another.

[0041] The first and second return devices 17, 18 are also identical. However, relative to the first mounting plate 13 and the second mounting plate 14, the return devices 17, 18 are arranged at 180° within the first and second mounting plates 13, 14, respectively. They are oriented identically relative to the first axis. The return devices 17, 18 use springs to ensure that the door handles are returned to their rest position after they have been pushed down to open or close the door.
