DE20309658U1 - Handle fitting for door or window, has four spaces in guide collar cooperating with four axial protrusions on counter sleeve - Google Patents

Abstract

The guide collar (16) contains at least four spaces (17) for cooperating with at least four axial protrusions (14) on the counter-sleeve (12). The fitting includes an escutcheon (1) containing a cavity (2) and a actuator shaft (6) which is rotatably mounted inside this cavity but can not be moved in the axial direction. The shaft has a handle (5) attached to one end and is surrounded by a flanged sleeve (15) secured to the escutcheon in a non-rotary manner. The side of the flanged sleeve facing the handle is provided with a guide collar extending in the circumferential direction. The spaces in the collar are radially opposed and trapezoidal shaped. A non-rotary counter-sleeve surrounding the shaft is mounted inside the handle cavity (10) and supported against a spring (11). The spaces in the counter-sleeve have the same trapezoidal shape as the spaces in the guide collar.

Door or window fittings

The invention relates to a door or window fitting comprising a plate with a plate recess and an actuating shaft which is mounted in the plate recess so as to be rotatable but axially immovable, which has a handle at a free end and is surrounded by a flange sleeve which is attached to the plate in a rotationally fixed manner, the flange sleeve having on its side facing the handle a guide collar extending in the circumferential direction with at least two radially opposite collar recesses and a counter sleeve surrounding the actuating shaft with at least two trapezoidal axial projections complementary to the collar recesses being arranged in a rotationally fixed manner in the handle recess and supported on a spring.

Such a door fitting is known (DE 33 20 193 C2). This ensures that if the effect of the lock spring of an associated lock decreases, inaccurate closing and sagging of a handle are avoided without the lock having to be replaced.

However, there are doors or windows whose handles have several functional positions so that the door or window can be moved from the rest position not only into the open position but also into a tilt position. To do this, the handle must be swiveled through certain angles, e.g. 90°, one after the other.

The object of the invention is to improve a door fitting of the type described at the beginning so that it is also suitable for doors or windows whose handles (levers) have several functional positions.

This task is solved by the guide collar having at least four collar recesses, to which at least four axial projections are assigned on the opposite side. Two of these collar recesses or axial projections are located radially opposite each other. With four collar recesses

recesses and axial projections, these are arranged at angles of 90° on the guide collar of the flange sleeve. Preferably, the trapezoidal sides that are inclined to a radial plane have an angle of 45° to the radial plane. If the handle has to be moved beyond the defined functional position of the handle to activate a desired function (open, tilt, close), then after the handle is released, the action of the spring, the counter sleeve with its axial projections and the flange sleeve with its collar recesses will return the handle to the defined functional position, and at the same time a lock connected to the other end of the actuating shaft or a lock gear connected to it will also be returned to its defined functional position.

In a preferred embodiment, the handle recess that accommodates the guide collar, the counter sleeve and the spring has at least one axial groove for the engagement of a radial projection of the counter sleeve. The counter sleeve is thus mounted in the handle recess in a rotationally fixed manner. Furthermore, the flange sleeve can have a radial flange on the outside of the shield and an axial flange extending into the shield recess, the axial flange having at least one radial projection that engages in an axial groove of the shield recess. The flange sleeve can thus be secured in the shield recess in a rotationally fixed manner in a simple manner.

In the following, an embodiment of the invention is explained, shown in the drawing;

The door fitting shown includes a plate 1 with a plate recess 2 which has a circular cross-section and four continuous axial grooves 3 arranged at the same angular distance from one another on the circumference. The plate recess 2 with the axial grooves 3 is formed by a bushing 4 which is inserted into an associated opening in the plate and fastened therein. The door fitting also includes a handle 5 which, in the version shown, is designed as a lever and from which an actuating shaft 6 extends which has a square opening on the inside for receiving a square section 7 and an annular groove 8 on the outside for a spring ring 9. The actuating shaft 6 is surrounded by a handle recess 10, at the base of which a spring 11 pushed over the actuating shaft 6 is supported. The other end of the spring 11 is supported on a counter sleeve 12 which is also pushed over the actuating shaft 6. The counter sleeve 12 has radial projections 13 which engage in associated axial grooves in the handle recess 10 and thereby secure the counter sleeve 12 in the handle 5 against rotation. On the side facing away from the handle 5, the counter sleeve 12 has four trapezoidal axial projections 14 arranged at equal angular distances from one another.

Furthermore, a flange sleeve 15 is pushed onto the actuating shaft 6, which has on its side facing the handle 5 a guide collar 16 with four collar recesses 17 congruent with the axial projections 14 of the counter sleeve 12. The flange sleeve 15 also has a radial flange 18 for contact with the outside of the shield 1 and an axial flange 19 engaging in the shield recess 2 with radial projections 20 engaging in the axial grooves 3 of the shield recess 2.

The handle 5 is inserted into the shield recess 2 with the spring 11, counter sleeve 12 and flange sleeve 15 pushed onto the actuating shaft 6 until the radial flange 18 of the flange sleeve 15 rests against the outside of the shield 1. The assembly thus prepared can then be secured with the aid of a spring ring 9 inserted into the annular groove 8, if necessary under

The locking device can be secured by inserting a snap ring 21. The square section 7 can then be inserted into the corresponding square opening of the actuating shaft 6. If necessary, a remaining distance between the spring ring 9 inserted into the ring groove 8 and a lock housing (not shown) can be bridged by a support ring 21. • Optionally, the shield 1 can also be provided with a shield cover 22, which is secured to the shield 1 with a grub screw 23.

In the embodiment shown, the axial projections 14 of the counter sleeve 12 are trapezoidal, with the trapezoid sides inclined to a radial plane having an angle of 45° to the radial plane. The same applies to the collar recesses 17 of the flange sleeve 15.

If the door or window fitting shown is connected via the free end of the square section 17 to a lock or a lock gear which has several functional positions, e.g. for opening, tilting and closing the door or window, then after pivoting the handle 5 until the desired functional position is reached and after releasing the handle 5, the latter is pivoted into a position defined by the desired functional position. The trapezoidal sides of the axial projections 14 of the counter sleeve 12 slide on the associated trapezoidal sides of the collar recesses 17 of the flange sleeve 15 and the counter sleeve 12, which is mounted in the handle 5 in a rotationally fixed but axially displaceable manner, rotates relative to the flange sleeve 15, which is mounted in the shield recess 2 in a rotationally fixed manner, until the handle has reached the defined position.
