FR2663071A1 - Universal square bar and self-locking assembly for door handle - Google Patents

Abstract

The door handle comprises a barrel (1) with two recesses (2) and (3) for a square bar (9) and a lever (4). The handle is assembled by fitting the square bar and the lever in their recesses and then locking the assembly by means of a supplementary translation of the lever.

Description

 The present invention relates to a door handle with self-locking modules.

 The invention therefore relates to the technical field of door handles for manually controlling a door closing device.

 All common types of door handles consist of a manual actuation part and made integral with a square rod penetrating into a housing of corresponding section of a rotary part of the closing device.

 Until then, the connection of the control part and the square rod is carried out most of the time, either by the installation of a nail passing through corresponding holes made in both the control part and the rod square, either by tightening a screw in a tapping of the control part which then locks by mechanical pressure against a face of the square rod, generally hollowed out specially at this location.

We observe that, according to these two most common types of joining of the handle and the square it is necessary to implement a separate component (nail, screw) and this using a non-simple process (threading a nail in successive holes that are manually translated relatively to make them coaxial, or screwing screws using a screwdriver)
The object of the invention is to propose a method of securing the handle and its square which is both simple to implement and, moreover, allows much more varied embodiments of the door handles thus meeting the ever more refined desires of users.

 To this end, the subject of the invention is a door handle of the kind with a manual actuation part integral with a control square of a door closing device, characterized, on the one hand, in that the manual part actuation is carried out in the form of a barrel inside which are arranged two perpendicular cylindrical housings, one of which is intended to receive the square and the second to receive a crutch, the conformations of the parts of the square and the crutch being provided in such a way that, after having first introduced the crutch in its housing, then after having introduced the square in its housing to come into intersection with the crutch, an additional movement of translation of the crutch in its housing ensures the joining manual actuation part and square.

 It is easily understood that the abovementioned conformations of the parts concerned with the square and the crutch can be produced in very different ways while allowing the self-locking operating mode between them of the modular parts of the door handle according to the invention (square , keg, and crutch).

 By way of non-limiting example, and to better understand the invention, a particular embodiment of it will be described below.

We will refer to the accompanying drawing, on which
FIG. 1 is an exploded perspective view representing the various modular parts of the handle according to the invention in their respective geometric positions allowing their correct implementation,
FIGS. 2 to 5 show in perspective four possible general gaits which can be obtained by combining two different shapes of barrel and crutch, and
FIG. 6 represents, in perspective, a universal square usable both with handles of the invention and with other common handles of the trade.

 We will first refer to Figure 1.

 The handle comprises a first modular part produced in the form of a circular cylindrical barrel (1) pierced by two cylindrical housings perpendicular to each other, one (2) with square section and the other (3) with circular section.

 The housing (3) is intended to receive the end of the same circular cylindrical shape of a straight stand (4). This end has an elongated lumen (5) whose successive widths are of values (L1) then (L2). A circular groove (6) receives an O-ring (7).

 For mounting the handle, first put the stand (4) in its housing (3) according to the arrow (F1) so that the width portion (L1) of the light (5) is just an extension of the housing (2).

We then fit the arrow (F2), with possible interposition of an elastic washer (8), the square (9) in its housing (2). The end of the square (9) has a rack (10) along its four faces. When the end of the square (9) has penetrated into the light (5), we push again according to the arrow (F1) the stand (4) and the rack (10) then comes to lock in the part of smaller width (L2) of light (5)
Figures 2 to 5 show different possible combinations using a barrel of shapes, circular cylindrical (11) or spherical (12) with a crutch of shapes, straight cylindrical (13) or curved cylindrical (14).

 Finally, Figure 6 shows a universal square. I1 comprises a square rod (9) with its rack (10) according to the invention, and also bores (15) for conventionally receiving an assembly nail, or an elongated concave housing in which abuts a locking screw.

Claims (2)

RESELL ICAT IONS  1) Door handle of the kind with manual actuation part integral with a control square of a door closing device characterized, on the one hand, in that the manual actuation part is produced in the form of a barrel (1) inside which are arranged two perpendicular cylindrical housings (2) and (3) one of which is intended to receive the square (9) and the second to receive a crutch (4), the conformations of the parts of the square and the crutch being provided in such a way as to quer after having first introduced the crutch (4) in its housing (3), then after having introduced the square (9) in its housing (2) to come into intersection with the stand, an additional translational movement of the stand in its housing ensures the attachment of the manual actuation part and the square.  2) Universal square usable in particular with a handle according to claim 1, characterized in that its end comprises both holes (15) for receiving nails, an elongated concave housing (16) for cooperating with a locking screw, and a rack (10) for cooperating with a light (5) of a stand (4).
