Description

The invention relates to a quick-assembly handle assembly for a door or window, comprising a square pin and a handle with a mounting piece and a handle part.

To operate doors or windows, handles are used which are coupled to an actuating device of the door or window via, for example, a coupling means in such a way that a torque from a rotary movement and also tensile forces can be transmitted. The actuating device is, for example, a nut of a door lock or a window gear. An L-shaped handle or a knob can be used as a handle.

Classically, a square pin is usually inserted as a coupling agent into a corresponding receptacle on the door lock or window gear, onto which the actual handle is inserted from the outside. A stud screw is usually arranged in the handle, with which the handle can be fixed on the square pin in the desired rotational position and the desired axial positions. This solution is simple, but unsatisfactory in several respects. On the one hand, assembly without axial play cannot be achieved reliably. On the other hand, the pen cover tends to come off after a long period of use, causing the handle to become loose.

From the publication EP 1 683 933 B1 A quick-assembly handle arrangement is known in which a connection between a square pin and a handle can be created quickly and without tools. For this purpose, a device is provided in the handle into which the square pin can be inserted in a first direction, but is locked in the opposite direction. The handle can simply be attached to a square pin that has already been inserted into the lock or window gear and is then installed. For this purpose, the device has a locking or clamping element which interacts non-positively, positively and/or frictionally with the square pin and which is pivotally mounted, the pivot axis of the locking or clamping element lying diagonally to the cross-sectional area of the square pin.

In one embodiment, the locking or clamping element is a disk with a square-shaped opening through which the square pin is guided. The disc only rests on one side of the device and is also pressed into an inclined position by a spring. When the handle is attached, the direction of movement brings the disc into a pivoting position against the spring action, in which there is no jamming with the square pin. When the handle is pulled back, due to the direction of movement and the spring preload, the disc is pivoted and jammed with the square pin.

In order to be able to remove the handle when replacing, servicing or repairing the lock or window gear, there is a hole in the handle into which a tool can be inserted to release the jam. However, the type and size of the tool as well as the positioning and movement required to release the jam are not intuitive to a user, so disassembly may prove to be problematic.

It is an object of the present invention to provide a quick assembly handle assembly in which both assembly and disassembly can be carried out easily and intuitively.

This task is solved by a quick-assembly handle arrangement with the features of the independent claim. Advantageous refinements and further developments are the subject of the dependent claims.

A quick assembly handle arrangement according to the invention of the type mentioned at the beginning is characterized in that the square pin has a spindle section with an external thread and the mounting piece has a freewheel assembly with a threaded sleeve with a thread into which the spindle section engages, the threaded sleeve being freely rotatable in only one direction of rotation. For assembly, the handle can simply be attached to the square pin, whereby the spindle section engages in the thread and rotates the threaded sleeve in its freewheeling direction. Retraction is not possible because rotation of the threaded sleeve against the freewheel direction is blocked. The pitch of the thread of the threaded sleeve and the spindle section are preferably chosen so that no self-locking occurs.

In an advantageous embodiment of the quick-mounting handle arrangement, the mounting piece has a hollow cylinder section in which the freewheel assembly is arranged, and a square receptacle into which a square section of the square pin engages in a rotationally fixed manner. The transmission of the torque when operating the handle therefore does not need to be absorbed by the freewheel assembly, which simplifies the construction of the freewheel assembly and reduces its material costs.

In a further advantageous embodiment of the quick-mounting handle arrangement, the freewheel assembly has a driver sleeve which is provided by Viewed from the square holder, it is positioned in front of the threaded sleeve and has a hole through which the spindle section is guided. With this arrangement, a freewheeling function can be achieved by friction between side surfaces of the two sleeves. This is possible in direct contact between the two side surfaces or via an intermediate and friction-increasing intermediate ring, which is made of rubber, for example. The side surfaces of one or both sleeves can also be grooved in order to increase the friction between them or with the intermediate ring.

The freewheel assembly preferably has a spring in order to press the threaded sleeve in the direction of the driver sleeve under spring force. Due to the spring preload, blocking occurs reliably and without slipping against the direction of freewheel rotation when the load changes from pressure to tension. The handle can thus be positioned correctly axially without play.

In a further advantageous embodiment of the quick-assembly handle arrangement, the driver sleeve can be secured in a rotationally fixed manner in the assembly piece using a fixing screw that is accessible from the outside. To dismantle the handle arrangement, the fixing screw can be loosened in a known and intuitive manner, whereby the driver sleeve can then be freely rotated in the assembly piece. A pull on the handle leads to a rotation of the unit consisting of the threaded sleeve and driver sleeve and, if necessary, the intermediate ring, which means that this unit can rotate around the spindle section and the handle can therefore be removed.

The fixing screw is preferably additionally guided through the handle part, whereby the handle part is fastened to the mounting piece without the need for an additional fastening means.

• 4 two isometric representations from different viewing directions of a threaded sleeve of the quick-assembly handle arrangement according to 1 and 2 .

1 shows an exemplary embodiment of a quick-assembly handle arrangement according to the present invention in an isometric exploded view.

The quick-assembly handle arrangement comprises a square pin 1, which can be inserted into a door lock or a window gear in a known manner. A handle is placed on the square pin 1, which includes a mounting piece 2 which is inserted into a handle part 4. A freewheel assembly 3 is arranged in the mounting piece 2.

The handle part 4 is designed, for example, as an L-shaped pawl, so it has a receptacle 41 running in the direction of the square pin 1, into which the mounting piece 2 is inserted, and a pawl section 42 running transversely to the receptacle 41. The invention can alternatively be used with a Handle part can be designed as a rotary knob.

The square pin 1 has a square section 11, which is followed by a spindle section 12 in the direction of the handle. In the spindle section 12, the square pin 1 is cylindrically shaped and provided with an external thread. The square section 11 is designed to be so long that it engages in the door lock or window gear and also protrudes beyond the door leaf or window frame. When placing the handle, the square pin 1 penetrates completely into the mounting piece 2 with its spindle section 12 and at least partially into the mounting piece 2 with the square section 11.

The mounting piece 2 has a hollow cylinder section 21 and - on the side facing away from the handle part 4 - a square receptacle 22. When the handle is placed on the square pin 1, a front part of the square section 11 penetrates into the square receptacle 22, so that the handle is connected to the square pin 1 in a rotationally fixed manner. In the outside area, the square receptacle 22 is cylindrical in a known manner with a diameter so that it can be stored in a door rosette or similar.

The freewheel assembly 3 is arranged in the hollow cylinder section 21 of the mounting piece 2, as shown in the sectional drawing 2 can be recognized. Specifically, the freewheel assembly 3 comprises two mutually rotatable sleeves, a driver sleeve 31 and a threaded sleeve 33. The driver sleeve 31 is first rotatably inserted into the hollow cylinder section 21 and is then fixed in terms of its rotational position with a fixing screw 32, which is preferably designed as an Allen head screw . The fixing screw 32 is also guided through the receptacle 41 of the handle part 4, so that it simultaneously holds the handle part 4 on the mount piece 2 attached. For this purpose, a thread is preferably formed in the handle part 4, into which the fixing screw 32 engages.

How 3 shows, the driving sleeve 31 has a through hole 311, the diameter of which is selected so that the spindle section 12 can be guided through the driving sleeve 31 and, if necessary, a part of the square section 11 into the driving sleeve 31. The driver sleeve 31 is provided with a corrugation 312 on one of the outer surfaces. This corrugation 312 points in the direction of the threaded sleeve 33.

The threaded sleeve 33 is in 4 shown in detail from two different perspectives. It has a threaded hole with a thread 331, matching the thread of the spindle section 12 of the square pin 1. In addition, an outside, specifically the outside facing the driver sleeve 31, is also provided with a corrugation 332.

The threaded sleeve 33 is pressed on the side facing away from the driver sleeve 31 via a spring 35 in the direction of the driver sleeve 31. The spring 35 in turn is supported on the opposite side on a plug 36, which is screwed, clamped and/or glued into the rear end of the mounting piece 2. Optionally, an intermediate ring 34 is arranged between the driver sleeve 31 and the threaded sleeve 33, in particular a ring made of an elastic material such as rubber, which increases friction between the driver sleeve 31 and the threaded sleeve 33.

When the handle is placed on the square pin 1, the spindle section 12 penetrates through the through hole 311 of the driver sleeve 31 and engages with its external thread in the thread 331 of the threaded sleeve 33. This is pushed away from the driver sleeve 31 by the interaction with the spindle section 12 against the spring force of the spring 35, whereby friction between the driver sleeve 31 and the threaded sleeve 33 (possibly via the intermediate ring 34) is essentially eliminated. Except for a small amount of friction, which comes from the spring 35 and the contact with the hollow cylinder section 21, the threaded sleeve 33 can then rotate freely. The increase in the thread on the spindle section 12 or the thread 331 is chosen to be so large that no self-locking occurs, as a result of which the threaded sleeve 33 rotates on the spindle section 12 when the handle arrangement is attached and the handle can accordingly be attached to the square pin 1 until the mounting piece 2 is correctly positioned in the abutment on the door or window.

If tensile forces are exerted on the handle arrangement, the spring 35 and additional tensile forces press the threaded sleeve 33, possibly with the intermediate ring 34, against the driver sleeve 31, which is fixed in the mounting piece 2 in a rotationally fixed manner via the fixing screw 32. The friction between the driver sleeve 31 and the threaded sleeve 33 (possibly with the inserted intermediate ring 34) leads, in particular due to the corrugations 312, 332, to the fact that the threaded sleeve 33 cannot be rotated, as a result of which the handle cannot be moved relative to the square pin 1.

To dismantle the handle arrangement, the fixing screw 32 can be loosened in a known and intuitive manner, for example using an Allen key. After the fixing screw 32 is loosened, the driver sleeve 31 can be rotated freely in the mounting piece 2, so that tensile forces on the handle lead to a rotation of the unit consisting of the threaded sleeve 33, if necessary the intermediate ring 34 and the driver sleeve 31, whereby this unit can rotate around the spindle section 12 and so that the handle can be removed. After tightening the fixing screw 32 again, the handle arrangement can be reassembled simply by pushing it onto the square pin 1.
