Abstract

A rosette-knob for use on e.g. pivot windows or terrace doors, where turning of an operating knob activates several different functions one after the other, comprises a pivotally mounted operating handle (7), which can be turned from an initial position against the action of a spring (11). The handle (7) engages by means of a cam with a pin (3), which can be moved by the turning of the handle. When the handle is in the initial position determined by the spring (11), the pin (3) is engaged with a recess on a blocking wheel (9) on the axle of the operating knob, but it is disengaged from the blocking wheel by a turning of the handle (7) against the force of the spring (11).

Description

Rosette-knob

The present invention conσerns a rosette-knob for use on e.g. pivot windows or terrace doors, where turning of an operating knob aσtivates several different funσtions one after the other. Such rosette-knobs are known with so-σalled σhildproof looking, whiσh prevents unintended turning of the knob beyond e.g. a tilting position or a ventilation position. However, the looking intervals in suσh known rosettes are limited to multiples of 90°. The purpose of the invention is to demonstrate a rosette- knob with the possibility of arbitrary plaσing of the σhild¬ proof positions.

This is achieved aσσording to the invention by the design indiσated in the σlaim, which makes it possible to σhange the bloσking positions simply by replaσing the bloσking wheel.

In the following the invention will be explained in more detail in connection with the drawing, where

Fig. 1 shows a rosette-knob acσording to the invention, seen from the front and partly out through, Fig. 2 shows some of the σomponents of the rosette in perspeσtive and separated from one another, Fig. 3 shows a stopping and bloσking wheel whiσh forms part of the rosette, seen from the side, and Fig. 4 shows the same wheel in perspeσtive. in a base plate 1 with various grooves or reσesses there is a groove 2, in whiσh a locking pin 3 can be moved. In the position shown in Fig. 1 the locking pin is engaged with re¬ cesses in a blocking wheel 9. The positions of these recesses are determined by the function the rosette is intended to have When the pin 3 engages with the blocking wheel 9, rotation of the wheel is prevented, and thereby rotation of an operating knob fastened to the wheel (which is not shown in the drawing) is prevented. The pin 3 is disengaged from the blocking wheel 9 by mean of an operating handle 7, which is- pivotally mounted in the ba plate 1. This operating handle 7 has a cam, which engages with a recess in the side of the pin 3. When the handle is turned to the right, the blocking wheel 9 and thereby the operating knob can be rotated freely. The operating handle is turned from the position shown in Fig. 1, where the pin 3 is engaged with the blocking wheel 9, against the force of a spring 11 placed in a groove 4 in the base plate 1 and compressed be- tween the end of the groove and a spring holder 8 on the operating handle 7. When the handle 7 is released, the spring 11 will tend to press the handle and thereby the pin 3 back into the initial position shown in Fig. 1.

Thus the result of this design is that the operating knob whiσh is σonneσted with the bloσking wheel 9, σannot be turned unintendedly beyond the movement that is determined by the reσess in the wheel 9 with whiσh the pin 3 is engaged, and suσh unintended turning of the operating knob σannot be made by young σhildren at all, as a σondition for further turning is that the pin 3 is disengaged from the bloσking wheel by means of the handle 7.

A stopping wheel 10 is σonneσted to the bloσking wheel 9. The stopping wheel keeps the operating knob in a predetermined position without looking. To move the operating knob out of a stopping position only a slightly inσreased pressure on the knob is required.

A blade spring 6 keeps the stopping wheel in position, an the plaσing of the reσesses in the stopping wheel is determine by the desired function of the knob.

Claims

P a t e n t C l a i m

Rosette-knob for use on e.g. pivot windows or terrace doors, where turning of an operating knob aσtivates several different functions one after the other, c h a r a c t e r i z e d by comprising a pivotally mounted operating handle (7), which σan be turned from an initial position against the action of a spring (11), by the fact that the handle (7) has a cam, by means of which it engages with a locking pin (3), which can be moved by the turning of the handle, and by the fact that when the handle (7) is in the initial position determined by the spring (11), the pin (3) is engaged with recesses in a blockin wheel (9) on the axle of the operating knob, but that the pin (3) is disengaged from the blocking wheel by a turning of the~ handle (7) against the force of the spring (11).
