Description

The invention relates to a handle for a door, French window

  and the like comprising a set of two crutches each provided with a fastening element fastened to the inner and outer faces of the door, French window and the like and a covering element secured to the fastening element, and a square rod maneuvering through the door, door or window and the like to operate at least one. locking element, the two ends of this square maneuvering rod being engaged in square holes made in

the shaft of each crutch.

  Maneuvering handles for a door, window-door and the like are already known consisting of a set of stands connected together by a square actuating rod making it possible to actuate either a locking element or

  a latch bolt, the follower of a cremone or espagnolette

  lock embedded in the edge of the opening of the door, French window or the like. These handles comprise as fastening elements and covering either rosettes or plates fixed on the inner and outer faces of the door, French window or the like. Generally, the square operating rod is secured to the shaft of one of the crutches and the other crutch, after passing through the door, door window or the like, is threaded onto the projecting end of the square drive rod. This second stand is made integral with said square drive rod by a vertical axis passing right through, respectively the holes made, on the one hand, in the shaft of the stand and on the other hand, in the end of the square drive rod engaged in said barrel. To make it possible to manipulate this vertical axis and / or to prevent the latter from falling out of the holes, said vertical axis presents to one of

  its ends a gripping head. -

  However, these operating handles have several disadvantages. One of these disadvantages consists in the fragility of the connection between the square operating rod and the second crutch. Indeed, the diameter of the vertical axis is small and, therefore, it is subject to a shearing effect, or the diameter of the vertical axis is relatively large requiring a corresponding diameter of drilling in the square rod of maneuver and considerably weakens the latter. Another disadvantage results from variations in the thickness of the door, French window and the like. To remedy this, we mainly know two ways but each with disadvantages. One of these means consists in producing in the square maneuvering rod a plurality of parallel holes arranged along the longitudinal axis of said rod. However, in this case, there is no progressive adjustment of the spacing between the two crutches but only a step adjustment

  corresponding to the center line of two consecutive holes.

  Another of these means consists in producing in the longitudinal center of the square operating rod a tapped hole in which a screw serving as a stop to the vertical axis can be screwed. However, because of the rotation maneuvers imparted to said rod, this screw is unscrewed which causes a separation of the two crutches causing a sliding

  transverse of the square maneuvering rod.

  The present invention aims to overcome these disadvantages. To this end, the invention relates to an operating handle for a door, a window and the like comprising a set of two legs each provided with a fastening element fixed on the inner and outer faces of the door, French window and the like, and a covering element made integral with the fastening element, and a square rod

  maneuver passing right through the door, carrying

  window or the like and making it possible to actuate at least one locking element, the two ends of this square operating rod being engaged in square holes made in the shank of each stand, characterized in that at least one of the fastening elements comprises tightening means exerting traction on the two stands, at least one of which is provided with compensating means and the other of which is provided with cooperating elastic connection means

  with one end of the square maneuvering rod.

  The advantages obtained by this invention consist essentially in that the handle can be used for doors, windows and the like of different thicknesses while condemning any transverse movement by elastic approximation of the two legs. Moreover, the connection between the stand and the square rod of maneuver is consolidated by eliminating any weakening of this

last.

  The invention will be well understood by referring to the

  following description given as a non-limitative example and

  to the attached drawing in which: - Figure 1 is an exploded view of an operating handle according to the invention, the fixing elements are rosettes; - Figure 2 is an exploded view of an operating handle according to the invention, the fastening elements are plates; - Figure 3 is an exploded view of a stand mounted on one end of the square drive shaft and provided with its compensating means; - Figure 4 is a plan view of the other crutch; - Figure 5 is an elevational view of the elastic connection means; FIG. 6 is a plan view of a fixing rosette; - Figure 7 is an elevational view and in section along the section line VII-VII of Figure 6; - Figure 8 is an elevational view in section of the elastic member providing traction by tightening crutches; Figure 9 is an elevational view of a fixing plate; - Figure 10 is an elevational view and in section according to

Referring to Figures 1 and 2.

  The operating handle 1, for actuating either a locking element or a latch bolt, or the follower of a espagnolette or espagnolette lock embedded in the edge of the amount of the opening of a door, door -Window or the like, consists of a set of two crutches 2, 3 interconnected by a square rod 4

  through the opening of the door,

  window or the like. This operating handle 1 is held by fastening elements 4, 5. Depending on the lock used, these fastening elements are either rosettes 5, 6 (see FIG. 1) or plates 7, 8 (see FIG. 2). fixed on the inner and outer faces of the opening of the door, French window or the like by

fastening means 9, 10.

  The rosettes 5, 6 or the plates 7, 8 are capped by a covering element having either a form of rosettes 11, 12 or a form of plates 13, 14 held on the rosettes 5, 6 or the plates 7, 8 by any means

but preferably by clipping.

  One of the ends 15 of the square drive rod 4 is engaged in a square hole 16 made in the barrel 17 of one of the stands 2, 3 and held in the latter by

  any means (see Figure 3).

  According to the invention, it is advantageous to be able to use the same operating handle 1 for doors, French windows or the like having a different thickness. Indeed, in most cases, doors, French windows or the like have a thickness of forty to forty-two millimeters. The length 18 of the operating rod 4 projecting from the shank 17 of the stand 2 is calculated as a function of the largest thickness, namely for a door, French window or the like whose thickness is forty millimeters. . To be able to use the same operating handle 1 for a door, French window or the like of a thickness greater than forty millimeters, one removes from said handle of

  maneuver 1 the compensating means.

  As can be seen in FIG. 3, these compensating means are a ring 19 whose thickness corresponds to the difference between the normalized thickness at forty millimeters and the actual thickness of the door, French window or the like. This ring 19 is threaded onto a bearing surface 21 made at the end 22 of the shank 17 of the stand 2 and comes to apply against the shoulder 23 located between the part 21 and the shank 17. After mounting the operating handle 1, the ring 19 is retracted between the fastening element (5 or 7) and the covering element (11 or 13) situated on the side of the

crutch 2.

  According to the invention, the operating handle 1 comprises

  elastic connection means. Referring to Figures 4 and 5.

  These connecting means are constituted by a clip 24 made of a spring steel. This clip 24 has an opening 25 and the two ends 26, 27 of the body 28 of this clip 24 can be spaced for the establishment of the latter in a circular groove 29 formed in the shaft 30 of the stand 3. The depth of this circular groove 29 is such that the clip 24 is embedded in the latter, the outer face 31 of the body 28 being flush with the outer periphery 32 of the barrel 30. The width of the circular groove 29 is at least equal to the width of the 24. Because the latter is embedded in the circular groove 29, the cover element 12, 13 can be slid on the shaft 30 of the stand 3 until clipped with the fastening element 6, 8. Furthermore, the clip 24 has a stud 33 protruding from the inner face 34 of the clip 24. This stick 33 has a diameter equal to the width of the clip 24 and through an orifice 35 made in the bottom 36 of the groove. circular 29. The said stick 33 is engaged r in a blind hole 37 (see Figure 3) made in the free end 38 of the square rod 4. Maneuvering-any risk of shearing the pin 33, it may have a relatively large diameter but this is not not at the expense of the strength of the square rod 4 maneuver because it includes only one hole 37 which is blind. However, the depth of this blind hole 37 must be such that the stick 33 does not prevent the retraction of the clip 24 in the circular groove 29. Moreover, because the stud 33 is secured to the clip 24, the constancy of the connection between the operating rod 4 and the stand 3. After mounting these elastic connecting means and in particular the clip 24 are located either between the fixing rosette 6 and the cover rosette 12 or between the fixing plate 8 and the cover plate 14 (see Figures 1 and 2). Because of the elasticity of the clip 24, it does not matter, on the one hand, the direction of engagement of the stub 33 and, on the other hand, the hole 35 and the blind hole 37 can be side or even underneath without there being a risk of breakage of the connection between the square drive rod 4 and the stand 3. As a result, the operating handle 1 can be used indifferently for a door,

  French window or the like opening to the right or to the left.

  By the way, the handle. 1 comprises tightening means exerting a traction on the two stands 2, 3, forannihiler any transverse sliding of the operating rod 4 may cause either a seizure of the connection between the latter and the locking element is a deterioration of the square hole said locking element and there is a risk that the square operating rod 4 no longer causes the element of rotation to rotate.

  locking. For this purpose, reference is made to FIGS. 6 to 10.

  These tightening means are at least one elastic washer 39 which is provided in a housing 40 made in the outer face 41 of one of the fixing rosettes 5 or in a housing 42 formed in the outer face 43 of one 7. The inlets 44, 45 of these housings 40, 42 comprise a circular narrowing 46, 47 in the form of steps in order to maintain the elastic washer (s) 39 in the housings 40, 42, the spring washers 39 have a shape one of the bases is preferably the small base 48 which is supported either against the ring 19 or against the shoulder 23 of the shaft 17 of the stand 2. During the mounting of the operating handle 1, it causes a compression of the elastic washer or washers 39 whose reaction causes traction on the stands 2 and 3. Thus the tightening means 39 are located between the fastening element 5, 7 and the covering element 11, 13 and are therefore , protected not just against any manipulation but

  also towards any external agent.

  On the outer face 41 of the fixing rosette 5, 6 is provided a circular clipping boss 54 cooperating with similar means which is provided with the inner wall of the

covering rosette 11, 12.

  The fixing plates 7, 8 comprise on their longitudinal edges 55, 56, clipping lugs 57, 58, 59, 60

  for holding the cover plates 13, 14.

  Although the invention has been described with respect to a particular embodiment, it is understood that it is in no way limited and that various modifications of shapes, materials and combinations thereof can be made. various elements, without departing from the framework and

the spirit of the invention.
