Description

TECHNICAL AREA

The present invention relates to the field of closure systems. It finds a particularly advantageous application in the field of door handles.

STATE OF THE ART

There are many systems for attaching a handle to an opening.

In order to allow the rapid attachment of a handle to an opening, handles comprising bases are generally used. These bases ensure effective fixing by flat support against the door wall. However, these bases do not offer guarantees in terms of security because they can be easily forced. In addition, for aesthetic purposes, these handles with bases do not always provide the desired result. It is therefore necessary to also be able to supply handles without base.

To do this, it is particularly known from the state of the art solutions such as the document EP3203000B1 in which a system for fixing a rotary handle to a sash opening is disclosed. In this technical solution, the fixing system comprises a main part, presenting a hooking element capable of being able to be secured at the level of a wall opening. This technical solution allows the attachment of a handle without a base. However, this solution has numerous limitations such as, for example, it does not allow easy adaptation to different wall thicknesses and therefore the cooperation between this solution and different opening walls is not optimal.

The documents FR2877979A1 And WO2016/020887A1 also disclose systems for attaching a handle to an opening. However, as the solution disclosed in the document EP3203000B1 , these solutions are not optimal, particularly with regard to cooperation with the opening walls.

An object of the present invention is therefore to improve the cooperation between a handle fixing system without a base and an opening wall.

The other objects, characteristics and advantages of the present invention will appear on examination of the following description and the accompanying drawings. It is understood that other benefits may be incorporated.

SUMMARY

• un corps présentant une première surface d'appui,
• un élément d'accroche présentant une deuxième surface d'appui, l'élément d'accroche traversant l'ouverture.

To achieve this objective and according to one embodiment, a device is provided for fixing a handle to a wall opening of an opening, the device comprising:

• a body having a first support surface,
• a hooking element having a second bearing surface, the hooking element passing through the opening.

The attachment element being secured to the body via a screw-nut system, so that screwing the screw-nut system allows the device to move from an unlocked configuration to a locked configuration, distinct from the unlocked configuration, locked configuration in which the first bearing surface and the second bearing surface grip the wall in a first direction.

Preferably the first direction is perpendicular to at least one of the first surface and the second surface.

Thus, the tightening of the hooking element is adjustable when mounting the handle by screwing in the screw-nut system. In fact, it is possible to vary the position of the hooking element in height relative to the body of the fixing system. We thus have a vice grip on the wall on which the fixing device is fixed. In addition, by having sufficient protrusion in the helical slide formed by screwing, we have a good latitude of adaptation to the type of walls, in particular according to their thickness.

Without the present invention, it would necessarily be necessary to replace the entire assembly of the device according to each opening thickness, which would inevitably increase production costs.

• positionnement de la première surface d'appui au contact d'une première face de la paroi,
• positionnement de l'élément d'accroche au travers de l'ouverture de sorte que la deuxième face d'appui soit au contact d'une deuxième face de la paroi, la deuxième face étant distincte de la première face,
• solidarisation de l'élément d'accroche au corps par l'intermédiaire d'une liaison vis-écrou, de sorte que, dans une configuration de verrouillage, la première surface d'appui et la deuxième surface d'appui se rapprochent l'une de l'autre jusqu'à venir prendre en étau la paroi selon une première direction.

Another aspect concerns an assembly comprising a wall on which the device is mounted. Another aspect relates to a method of fixing a handle to a wall opening of an opening using a device comprising a body having a first bearing surface and a hooking element having a second surface. support, the process comprising the following steps:

• positioning of the first support surface in contact with a first face of the wall,
• positioning the hooking element through the opening so that the second support face is in contact with a second face of the wall, the second face being distinct from the first face,
• securing the attachment element to the body via a screw-nut connection, so that, in a locking configuration, the first bearing surface and the second bearing surface approach each other on the other until it grips the wall in a first direction.

DETAILED DESCRIPTION

Before beginning a detailed review of embodiments of the invention, the following are set out as optional characteristics which may possibly be used in combination or alternatively:
According to one example, the body comprises a first angled surface and the gripping element comprises a second angled surface, the two angled surfaces being configured so that in the locking configuration, the first angled surface and the second slanted surface are in planar contact with each other so as to allow transmission of load pickups both in the first direction and radially to the first direction X.

According to one example, the second slanted surface extends along a plane forming an angle with the second support surface of between 30° and 60°, preferably substantially equal to 45°. According to one example, the hooking element is configured to pass entirely through the opening, the opening being delimited along an opening surface and extending through the wall along a central axis, parallel to the first direction. Preferably, the opening is a circular opening. Preferably the opening is accompanied by at least one centering opening. Preferably two centering openings, which can be distributed symmetrically around the circular opening.

According to one example, the hooking element has a connecting face configured so as to exert pressure on the opening surface in a locking configuration.

According to one example, the device comprises at least two hooking elements, preferably exactly two hooking elements distributed symmetrically around the central axis. According to one example, at least two attachment elements are distributed symmetrically or equiradially relative to the central axis.

According to a particular embodiment, the device comprises at least three attachment elements distributed equiradially around the central axis.

According to one example, the body and the hooking element respectively comprise a first tapping and a second tapping, the first tapping and the second tapping having the same diameter and are both configured so as to cooperate with a threaded element in order to allow the body to be secured to the hooking element.

According to one example, the threaded element comprises a clamping interface, the clamping interface being accessible from the space oriented towards the first face.

According to one example, the hooking element comprises a connecting surface extending between the second bearing surface and the second oblique surface, the device being configured so that in a locking configuration, the threaded element is 'rests on a radial support surface.

By “wall” we mean an amount or a leaf which can allow access or closure of access, it is not necessarily a hinged door, it can also be a sliding door wall, such as for example a bay window.

In the remainder of the description, the term “on” does not necessarily mean “directly on”. Thus, when we indicate that a part or an organ A is supported “on” a part or an organ B, this does not mean that the parts or organs A and B are necessarily in direct contact with the other. These parts or bodies A and B can either be in direct contact or be supported on one another via one or more other parts. It is the same for other expressions such as for example the expression “A acts on B” which can mean “A acts directly on B” or “A acts on B through one or more other parts ".

Furthermore, when two pieces “A” and “B” grip a piece “C”, this does not necessarily mean that there would not be an additional piece inserted between “A” and “C” and/or or between “B” and “C”.

In the context of this patent application, the expression “kinematically interposed between” does not necessarily mean not in “contact with”. Thus, if a part A is kinematically inserted between a part B and a part C, this does not mean that A and B are necessarily in direct contact or that A and C are necessarily in direct contact. This means that a movement or an effort from part B, respectively from part C, can be at least partly transmitted to part C, respectively to part B, via part A.

In the present patent application, the term mobile corresponds to a rotational movement or a translational movement or even to a combination of movements, for example the combination of a rotation and a translation.

• positionnées à distances l'une de l'autre, et/ou
• mobiles l'une par rapport à l'autre et/ou
• solidaires l'une de l'autre en étant fixées par des éléments rapportés, cette fixation étant démontable ou non.

In the present patent application, when it is indicated that two parts are distinct, this means that these parts are separate. They are :

• positioned at distances from each other, and/or
• mobile relative to each other and/or
• secured to each other by being fixed by attached elements, this fixing being removable or not.

A one-piece unitary part cannot therefore be made up of two separate parts.

In the present patent application, the term "integral" used to describe the connection between two parts means that the two parts are linked/fixed relative to each other, according to all degrees of freedom, unless it is explicitly specified differently. For example, if it is indicated that two parts are united in translation in a direction piece in direction X, the other piece performs the same movement.

In the present patent application, an elastic means or element may for example be a spring, such as a helical coil spring, elastic washers such as Belleville washers, an elastomer, a rubber.

In the detailed description which follows, use may be made of terms such as “horizontal”, “vertical”, “longitudinal”, “transverse”, “upper”, “lower”, “top”, “bottom”, “front », “rear”, “inside”, “outside”. These terms should be interpreted relatively in relation to the position of the entire device worn by the swimmer and in a configuration in which the swimmer is standing on land or underwater.

According to a preferred embodiment of the present invention, the fixing device 1 allows the fixing of a handle 3 on an opening. Preferably the opening has a wall 21 having an opening 211. The device 1 comprises a body 11 having a first bearing surface 11a adapted to be preferably in plane contact with a first face 21a of the wall 21 of the opening 2.

The two slanted surfaces 11b, 12b are preferably configured so that when screwing the screw-nut system, the first slanted surface 11b and the second slanted surface 12b come closer to each other until they allow a plane contact of the two surfaces. Thus, once contact has been made between the two surfaces at an angle, this allows transmission of the loads taken up both in the first direction X211 and in a direction perpendicular to the first direction X211, preferably in a direction radial to the first direction X211.

• une première phase d'amenée dans laquelle la deuxième surface en biais 12b est sensiblement parallèle à la première face 21a,

According to one example, the threaded element 13 comprises a clamping interface, the clamping interface being accessible from the space oriented towards the first face 21a. The clamping interface can be a screw head or a bolt head.

According to a particular embodiment, the hooking element 12 comprises a connecting surface 12c extending between the second bearing surface 12a and the second slanted surface 12b. Thus, the device 1 is configured so that in a locking configuration, the threaded element 13 rests on a connecting surface 12c so as to prevent the threaded element 13 from unscrewing.
