Description

The present invention relates to the field of immobilization devices for wings, especially for doors, more particularly electromagnetic bands maintaining the flap by electromagnetic attraction and relates to a set for the production of electromagnetic bands of different heights.

It is known that an electromagnetic strip intended to equip a door to lock the closure leaf in place of a conventional bolt lock has a height determined according to said door and comprises a first section may be fixed on the block or frame of the door and a second section that can be fixed on the leaf.

The first section is hollow and rectilinear, generally of square or rectangular section, and comprises two opposite longitudinal faces, one or rear face is intended to be applied to a surface of the block or dormant frame and the other or front or apparent face comprises one or more usual openings each receiving an electromagnet. The second profile is also hollow and rectilinear, generally with a generally U-shaped cross-section, usually comprising a wing extending laterally one of the longitudinal edges of the U and being intended to be applied to a surface of the wing so as to allow said second section to be fastened thereto. latest. In addition, the second section frequently comprises a handle portion constituted by a wing extending laterally said profile substantially at its bottom.

On the other hand, the first section is associated with electrical connection means and control means necessary for the proper operation and control of each electromagnet, while the second section is equipped with at least one counter plate, fixed in the U, adapted to cooperate in the closed position of the door with the corresponding electromagnet with the effect of maintaining the wing, in the plane of the frame, by electromagnetic attraction.

However, the doors are not all the same height, which requires the operator to install a profile whose length is adapted accordingly. This is then obliged to cut the profile to the desired length to be able to adapt to the height of the door or the beating, which is binding for the operator. Another solution available to him is to store profiles of different lengths, but this solution requires a storage space adapted to store the latter and forces the operator to always check and, possibly to feed, regularly his stocks to be able to benefit at all times from the right profile length.

The object of the present invention is to overcome these disadvantages by proposing an assembly for the production of electromagnetic strips of various heights which avoids the need to perform the necessary cutting operations with the current profiles or to store profiles of different lengths and to regularly check the stock to permanently benefit from all profile lengths.

Each second endpiece 24 can be fixed to a free end of a second base section 8 by means of a snap-fit connection and, preferably, by fixing by means of one or more screws 12 'or the like which can be screwed at the same time. in the second endpiece 24 concerned and in the free end of the corresponding second base section 8 and preferably in the base fixing flange 21 of the latter which is then intended to extend to said free end. To achieve the interlocking, each second endpiece 24 may comprise, for example, at least one lug or pin 25 adapted to be inserted into an opening and preferably into one of the interlocking openings 23 serving to receive the corresponding portion of a junction plate 9.

The nesting apertures 23 of each second base section 8 can advantageously be made by the space under the fastening flanges as defined in the patent no. FR 2,884,273 filed by the present applicant, so as not to modify the existing profiles or not to complicate their manufacture by the addition of additional and specific interlocking openings.

Note that in the case of the second main section 4, the or each second base section 8 constituting the latter can be fixed directly to the second surface by its lateral fixing flange, while in the case of the first main section 2, the or each first base section 6 constituting the latter can be fixed on the first surface by means of the connecting pieces 7 which are fixed on said first surface prior to their junction with said first basic sections.

Therefore, in the preferred embodiment of the present invention, it will be understood that the first connecting means 7 provide both the junction or connection function of the first base profiles 6 connected by their free ends and whose axes of these are arranged, along the same axis or the same straight line, in the extension of one another, and the function of fixing the latter on the first surface, while the second connecting means 9 provide only the junction or connection function and in particular centering second base profiles 8 for the arrangement of the axes of the latter along the same axis or the same straight line, in the extension of one another.

Finally, it will be noted that in the case where the first main section 2 is made from a single first base profile 6, for example because the height of the door to be equipped is reduced, said base profile 6 can be fixed either by means of two connecting pieces 7 fitted at each of its free ends after attachment of said parts 7 to the first surface, or, preferably, by means of two first end pieces 17 fixed on the first surface and then nested in the free ends of said single base section 6 of the strip 1 to achieve.

Note that, in the embodiment of a strip 1 from an assembly according to the present invention, the first end pieces 17 can then play a role of both finishing and fixing by allowing, like the pieces of junction 7, the attachment of a single base section 6 or, in the case of a plurality of base profiles 6, one of the free ends of the two base profiles 6 located respectively at the upper or lower end the first main section 2 of said strip 1 thus produced, while the second end pieces 24 can play only a finishing role of the second main section 4 fixed by other means and in particular by its main fixing flange.
