EP2076645B1 - Belt for electromagnetic sucker - Google Patents

Abstract

A belt for electromagnetic sucker includes a first substantially U-shaped section, a second substantially U-shaped section, an electromagnetic sucker coupled to at least one of the first and second substantially U-shaped sections, at least one of the first and second substantially U-shaped sections being structured and arranged to be secure to a support, and a connector structured and arranged to secure the first and second substantially U-shaped sections to one another.

Description

The present invention relates to improvements to the bands with electromagnetic suction pads.

As is known, a suction cup is, in fact, an electromagnet attached to the periphery of an opening and capable, when excited, retaining a backplate fixed on the door, or vice versa.

In the state of the art, the suction cup is fixed in a profile, called bandeau, fixed, itself against the support (wall or door), cf. FR 2 865 230 A .

The strip is in the form of a tubular section, having on one of its faces an opening cut to allow the introduction and fixing of the suction cup. This opening is advantageously used to access the other face of the profile and allow the attachment of the assembly on the support.

Experience has shown that this localized fixing was insufficient on the long strips and, in this case, it was necessary to use additional screws through the two opposite faces of the profile with all the risks that this presented.

• la longueur des câbles doit être bien supérieure à la longueur séparant l'orifice d'introduction de ceux-ci et les bornes de la ventouse et cette longueur doit ensuite être réintroduite dans le bandeau ;
• la mise en place de la ventouse doit être effectuée sur le site et après raccordement des câbles ;
• Le contrôle des connexions nécessite le démontage de la ventouse.

The implementation of these strips is not practical because the passage of the power supply cables is problematic. Indeed, the cables must be connected to the suction cup before fixing it in the headband, which implies the disadvantages below:

• the length of the cables must be much greater than the length separating the insertion orifice from these and the terminals of the suction cup and this length must then be reintroduced into the strip;
• the installation of the suction cup must be carried out on the site and after connecting the cables;
• Connection control requires disassembly of the suction cup.

The strip of the invention, which overcomes these drawbacks, is remarkable in that it consists of the combination of two sections, each of which has a substantially U-shaped section, one of which carries the suction cup and comprises means for allowing its attachment to the support, while the other is intended to cover the first, means being provided to allow the joining of the two assembled sections.

• la figure 1 est une vue en coupe transversale d'un bandeau, conforme à l'invention, en cours de pose ;
• la figure 2 est une vue analogue à la figure 1, le bandeau étant posé ;
• la figure 3 est une vue partielle du profilé de support de la ventouse .

The present invention will be better understood from the following description given with reference to the accompanying drawings by way of indicative example only, in which:

• the figure 1 is a cross-sectional view of a strip, according to the invention, being laid;
• the figure 2 is a view similar to the figure 1 , the headband being laid down;
• the figure 3 is a partial view of the support profile of the suction cup.

Referring to the drawings, we see that the strip is formed by the combination of two sections 1 and 2, U-shaped section, the section 2 can completely cover that 1.

The profile 1 is provided to allow the attachment of the suction cup V. According to the invention, the suction cup is fixed in the profile previously to the fixing said profile on the support S. Generally, this fixing is performed at the factory.

According to one embodiment, the middle portion 3 of the profile has a longitudinal groove 4 whose bottom serves as a support for the suction cup V which is held by screws 5 passing through the bottom of said groove, which, as is apparent from FIG. figure 3 , has holes 6.

The middle portion 3 has orifices 7, preferably oblong, through which the screws 8 attach the profile against the support S.

The middle part of the profile 2 has an opening 9 for passage of the suction cup.

After fixing the profile 1 and then having connected the power cables (not shown), the assembly is covered by the section 2, which behaves like a hood. Any conventional means can be used to fix the profile 2 to that 1.

Thus we can use screws whose axes are diagrammed at 10 on the figure 2 . The profile 2 can be clipped onto the one 1.

As regards the attachment of the suction cup, this can be achieved by screws passing through the wings of the profile 1, such as those 11, shown in dotted lines on the figure 1 . In this case, it is not mandatory that the suction cup bears against the bottom of the groove 4.

Claims (2)

1. A belt with an electromagnetic sucker, characterized in that it consists of the association of two sections (1-2) each having a cross-section in the form of a U, one of which bears the sucker (V) and includes means for allowing the fastening thereof to a support (S), whereas the other one is intended to cover the first one, means being provided for fastening the two assembled sections together.
2. A belt according to claim 1, characterised in that the middle part (3) of the section (1) has a longitudinal groove (4).
