Description

Door handle

The invention relates to a door handle with a handle that releasably seated on a square pin that extends through the lock nut and is split in the longitudinal direction, in one of the Pin cross-section corresponding cavity of the handle engages, and by means of a Uegelspitze having in the Handle neck screwed in expansion screw pressed apart is, wherein bevels are provided as the contact surface of the expansion screw on the pin halves.

Door handles of this type are known not always a tight fit in the lock follower penetrated by the square pin, because the square pin is in the In order to be able to insert the lock nut, it must have at least a small amount of play · When tightening the expansion screw a spreading of the two pin parts is only possible until the pin is firmly attached to the side walls of the detachable

The existing square hole is pressed onto the handle. As a rule, this slight expansion is not sufficient to create a to get a secure fit in the lock follower.

The invention now aims to provide a door handle of the aforementioned Genus are designed so that the printer pen also is firmly seated in the lock follower. This is according to the invention achieved by the fact that the pen halves are fixed at a distance from each other in the non-detachable handle, are preferably cast, and that the pin before tightening the expansion screw in the direction of the later apart pressure intervenes with play.

With a pusher designed in this way, the pin can after Sliding the detachable handle onto this can be spread so far that there is still a notable one in the area of the lock follower Increase is present. This is achieved in that the hole in the handle is provided as a result of the * The fact that the two halves of the pen are not prevented from spreading wider than the rest of the game also helps ensure a firm fit are held at a distance from each other in the other door handle. Due to the gap between the halves of the pen that are underneath Overcome their spring force can be pressed together, a certain preload can be provided, while overcoming it the square pin can be inserted into the lock follower without play.

The gap between the "two halves of the pen" can open can be achieved in different ways. In a preferred embodiment there is between the pin halves in the area their seat in the non-releasable handle an intermediate layer, for. B. arranged a sheet. When using such In the intermediate layer, the two halves of the pen can be poured in at a distance from one another very easily without affecting special precautions would have to be taken for the pens. But you can also use the pen halves at least in the area roughen their seat in the non-detachable handle or provide them with cams. If you do this, then there is an intermediate layer dispensable.

The following example is given as the order of magnitude for the required game? With a total cross-section of the square pin of 8x8 mm is the hole cross-section in the detachable Handle conveniently 8 χ approx. 8.5 mm, with the dimension of approx. 8.5 mm in the direction in which the both halves of the pusher pin when tightening the expansion screw evade·

According to an advantageous development of the invention is Expansion screw a hexagon socket screw · With such a hexagon socket screw, much greater forces can be applied than with a slotted screw, where experience has shown that the screwdriver slips easily. Also has a turned off

Wrench for a hexagon socket head screw is essential larger lever arm than a screwdriver.

In the drawing, an embodiment of the invention is shown j it show

Fig. 1 is a partially sectioned view of a lever handle with two handles looking perpendicular to the door edge and parallel to the door surface,

Fig. 2 is a view from above, the door being indicated by dash-dotted lines,

Fig. 3 a section along line III-III in Fig. 1 and

Fig. 4 shows a section corresponding to Fig. 3, but with the expansion screw loosened.

The door latch essentially consists of handles 1 and 2 and the handle pin designated as a whole with 3. The handle pin 3 extends through the lock follower 4 in the Drawing not shown door lock. It is clear that by pressing buttons 1 and 2, the lock follower is rotated because the trigger pin is held in the handles and 2 as well as in the lock follower 4 so that it cannot be rotated.

The cross section of the pusher pin 3 can be seen in FIGS. These figures show that the Lever pin made from two solid rectangular profiles of the same shape 5 consists. These rectangular profiles 5 are insoluble in

the handle 1 cast. In order to form a slot 6, a distance between the rectangular profiles 5, an intermediate layer 70 is inserted between these, which extends approximately to the end of the neck 8 of the Handle 1 is enough.

A hexagon socket screw 7 is used to fasten the detachable handle 2, which is inserted into a handle 2 provided threaded hole 80 is screwed. The screw 7 has an ISegelspitze 9 with a cone angle of about 90 °. This cone tip engages in the clamped state of the handle 2 in a wedge-shaped fury 10, one of which is a wedge surface on a of the pin halves 5 and the other wedge surface thereof is integrally formed on the other of the pin halves 5. How in particular Fig. 2 shows, the nuttie takes | £ e from its end of the pin to the lying end towards the center of the pin, which can also be seen in Fig. 1 by the increasing groove width is. The wedge angle of the groove and the taper angle of the hexagon socket screw 7 are the same.

In the plan view according to Fig. 2, the door is indicated at 11 by dash-dotted lines. From Fig. 2 it can be seen that the axis 12 of the pressure screw 7 perpendicular to the door edge 13, so runs horizontally in the room.

The cavity 17 of the handle 2 has a rectangular cross-section, the dimension a (see Figure 4) being slightly smaller as the measure b. For example, the dimension a can be 8 mm and the dimension b approx. 8.5 mm if the cross section of the pin 3 8 χ 8 mm. The relationships are shown in Fig. 4 for clarification exaggerated. In fact, the game is not as big as shown in Fig. 4.

The door handle according to the invention is assembled as follows. First of all, the lever pin 3 is inserted into the door handle 1 firmly inserted, preferably by pouring. The intermediate layer 70 ensures that the two halves of the pin 5 have a distance 6 from one another which is equal to the thickness of the intermediate layer 70. When installing on the The square pin 3 is pushed through the lock follower 4 to the door « pushed through until the stop edge 14 of the handle rests against the door or a rosette. The slot 6 can so be chosen so that the pin halves 5 gape so far that there is a slight compression of the pin halves 5 required to allow insertion into the lock follower. After inserting it into the lock socket, it becomes detachable Handle 2 pushed until its stop feante 14 'on the Lever handle rosette. Then, using a hexagon socket, which can be set unhindered due to the special position of the screw 7, the expansion screw 7 tightened. The cone tip 9 presses the

two halves 5 of the pusher pin 3 apart, so that its surfaces 15 are pressed against the walls 16 of the handle cavity 17. The i.ex pin walls 15 are also pressed against the walls 18 of the lock follower opening, so that both a firm hold of the handle on the pin and a firm hold of the pin in the lock follower are achieved. The pin halves can be pushed far enough apart because dimension b (see Fig. 4) is slightly larger than the thickness of the square pin. Regardless of the door thickness, the pressure screw always engages in the area of the rise on the outwardly rising wedge-shaped groove, so that a firm hold against tension from the side is achieved.Since the key for inside * hexagon screws are bent at right angles and the If it is not possible to remove the key from the screw, the hexagon socket screw can be tightened very firmly so that the screw will not be loosened or the pin halves will not be pushed apart improperly.
