DEVICE FOR FASTENING RADIATOR ACCESSORIES

The present invention relates to a device for attaching radiator accessories, and more particularly to a device for attaching bathroom accessories to a radiator with bars or heating tubes.

European Patent Application EP0387842 discloses a device configured to attach accessories such as a towel rail to a tube heater. This device comprises a rear part placed between two adjacent tubes of the radiator and a front part having a fitting part intended to be received in the hollow end of a towel rail, to which it is fixed by an Allen screw passing through a hole in the wall of said hollow end. The device includes a bolt connecting the back piece to the front piece while passing between the two adjacent tubes.

Such a device has the disadvantage of being adapted to only one type of accessory. On the other hand, disassembly is relatively uncomfortable because the bolt is masked by the connection.

There is therefore a need for an accessory attachment device to a radiator that is versatile and able to be mounted / disassembled conveniently and quickly.

The applicant company proposes to solve this problem by the use of a radiator accessories fixing device which comprises means of solidarisâtion of the device configured to fix the constituent elements of the device to each other while allowing the fixing of accessories to the device using the fastening means initially provided for attaching the accessory to its support.

The subject of the present invention is therefore an accessory attachment device for a blade or tube radiator, comprising: a rear part comprising a bearing face through which the rear part is intended to come into contact with the rear side; radiator, and a hole opening into the bearing face, - a front part comprising a bearing face through which the front piece is intended to come into contact with the front side of the radiator, a face of attachment opposite to the face. support and through which an accessory will be attached to the device, and a through-hole cylindrical opening into the bearing face and into the attachment face, and - means for securing the rear and front parts, characterized in that: - The solidarisâtion means comprise a screw adapted to be threaded through the through hole of the front piece and be screwed, by its free end, into a thread that has the hole opening the rear part, - the through hole of the front piece is adapted to also receive the head of the screw, and - the front part comprises locking means in rotation of the screw when the head of the screw is received in the hole crossing the front room.

With the above configuration, the solidarity means do not interfere with the outer surface of the front piece, in particular the fixing face and the peripheral wall connecting the fixing face and the bearing face of the front piece, so that the user can attach to the piece before his accessory using the fastening means initially provided.

In particular, the present invention takes advantage of the fact that the majority of accessories, including bathrooms, such as cup holders, mirror holders, comprise on the one hand a plate which is intended to be fixed to the wall, for example by screws or gluing, and, secondly, the accessory itself, which is fixed to the plate, generally removably, and which includes an aesthetic covering the plate and concealing it. Each accessory, and in particular each accessory manufacturer, may correspond to a specific method of attachment to the plate, such as for example by gluing, screwing, screw clamping, etc.

With the device according to the present invention, the user can fix the plate to the front part of the device, in particular to the attachment face of the front piece, in the manner initially intended for fixing the plate to a wall, then the user can attach to the plate, and therefore to the front piece, the accessory with again the attachment mode initially provided for 1 'accessory.

Consequently, the device according to the present invention makes it possible to fix to a radiator with blades or tubes, in a manner that is removable, convenient and fast, a great variety of accessories, in particular bathroom accessories, without modifications of the latter, especially for the accessories originally intended for wall mounting.

It is pointed out here that the above mentioned radiator with blades or tubes designates any radiator with blades or tubes, but that the present invention finds a particular application to the radiators towel.

According to a particular embodiment, the screw is a screw with a polygonal head, in particular hexagon head, and the rotational locking means are constituted by a portion, such as the end, of the through-hole side of the fixing face of the front piece. which part is of corresponding polygonal shape, possibly hexagonal.

According to a particular embodiment, the thread that has the hole opening of the rear part is the thread of a nut mounted fixed in position in said through hole, preferably a polygonal nut, including hexagon, fixedly mounted in position in a housing formed in a rear face, opposite to the bearing face, of the rear part, which housing is of corresponding polygonal shape, where appropriate with six sides.

Of course, the thread that has the hole opening of the rear piece may be simply formed by at least one thread extending on the inner wall of the through hole.

Preferably, the rear part has a truncated portion of cone of revolution whose small base and the lateral face form the bearing face of the rear piece, the longitudinal axis of the opening hole of the rear piece being perpendicular to the small base of the truncated cone of revolution.

Preferably, the bearing face of the front piece comprises stepped portions.

The bearing face of the front piece can be a continuous surface. The bearing face of the front piece may alternatively be formed by the free edges of at least one circular rib and / or at least one straight rib, the circular rib or ribs extending around and the rib or ribs straight extending from a solid central portion in which is formed the through hole of the front piece.

The attachment face of the front piece may advantageously be flat.

Preferably, the attachment face of the front piece has a curved central groove.

Advantageously, the front piece has the outer shape of a disc. "Disc" here means a cylindrical piece whose height is less than the diameter.

To better illustrate the object of the present invention will be described below, by way of illustration and not limited to, a particular embodiment, with reference to the accompanying drawings.

In these drawings: - Figure 1 is a perspective view of the radiator accessory fixing device mounted on a radiator; - Figure 2 is a perspective view of the rear part of the device of Figure 1, side support side; - Figure 3 is a perspective view of the rear part of the device of Figure 1, rear side; - Figure 4A is a perspective view of the front part of the device of Figure 1, side support side; - Figure 4B is a perspective view similar to Figure 4A, a front part according to a variant of the device of Figure 1; Figure 5 is a perspective view of the front part of the device of Figure 1, fixing face side; Figure 6 is a cross-sectional view of the device of Figure 1; - Figure 7 is a perspective view of the device equipped with a mirror type accessory; and - Figure 8 is a perspective view of the device of Figure 1 equipped with a cup holder type accessory.

Referring first to Figures 1 and 6, it can be seen that there is shown the radiator attachment device 1 mounted on a radiator R. The device 1 is configured to be mounted between the blades L or tubes T of a heating radiator R.

The device 1 comprises a rear part 2, a front part 3 and fastening means 4 configured to fixably assemble the rear part 2 and the front part 3. The term "front" means the radiator side R facing towards the outside. environment to be heated, and therefore by "front piece 3" the part intended to be mounted front side of the radiator R. "Back" means the other side of the radiator R, generally facing a wall or any suitable support of the radiator R, and thus by "rear part 2", the part intended to be mounted on the rear side of the radiator R.

Referring now to Figures 2 and 3, it can be seen that there is shown the rear part 2. The rear part 2 comprises a bearing face 5 intended to bear against the radiator R and a opposite back face 6. In particular, the rear part 2 is in the form of a truncated cone of revolution 7 whose small base 7a, which is circular, and the lateral surface 7b form the bearing surface 5. In the example illustrated on Figures 2 and 3, the truncated cone of revolution 7 is extended from its large base by a cylindrical portion 8 whose free end face constitutes the rear face 6.

Depending on the spacing between the blades L or the tubes T of the radiator R, the rear part 2 will bear against the blades L or tubes T by the small base 7a or the lateral surface 7b (as shown in Figure 6) . The advantage of the truncated cone of revolution 7 is that in use it offers both a vertical face (small base 7a) allowing a correct support against the vertical rear faces of the blades L, and an inclined lateral surface 7b allowing a correct support either against the horizontal rear edges of the blades L (depending on the inter-blade spacing), or against the circular surface of the tubes T. The rear part 2 will be dimensioned for this purpose, and we can mention here an example of dimensioning: diameter of the small base 7a = 20 mm, height of the truncated cone 7 = 10 mm, diameter of the large base = 35 mm, length of the cylindrical part 8: 5 mm.

The rear part 2 comprises, centered in the latter, a through hole 9 opening into the center of the small base 7a, as can be seen in FIG. 2, and in the center of the rear face 6, as can be seen that the

Figure 3 The through hole 9 has on its inner surface a thread that can be formed directly by a thread on the inner wall of the through hole 9, or be formed by an insert as described below.

Referring more particularly to Figures 3 and 6, it can be seen that the rear face 6 has a housing 10 whose center is aligned with the center of the through hole 9 opening to the rear face 6. The housing 10 has a bottom parallel to the bearing face 5 and a peripheral surface of hexagonal shape. The role of housing 10 will be explained below.

Referring to Figures 4A and 5, it can be seen that there is shown the front part 3. The front part 3 has a bearing face 11 intended to come into contact with the front side of the radiator R and an opposite fixing face 12, through which the accessories are fixed to the device 1. The front part 3 is here of cylindrical shape and the bearing face 11 and the fixing face 12 are disk-shaped and parallel.

The bearing face 11 is a continuous surface which has steps, with a first rectangular and planar central portion 13 extending over a diameter of the bearing face 11, two symmetrical second symmetrical portions 14a, 14b relative to each other. at the first central portion 13, and two symmetrical third portions 15a, 15b symmetrical with respect to the first central portion 13. The first central portion 13, the second symmetrical portions 14a, 14b and the third symmetrical portions 15a, 15b are respectively contained in three different and parallel planes, the plane containing the first central portion 13 being located furthest outward of the front piece 3 and the plane containing the third symmetrical portions 15a, 15b being located furthest inwardly of the 3. Thus, as can be seen in FIG. 6, similarly to the bearing surface 5 of the rear part 2, the first central part 13 is intended to come against two blades L or tubes T of the radiator R, possibly slightly in the spacing between them. The fact that the bearing face 11 of the front piece 3 is of the stepped type makes it possible to fix the device to different types of radiators, for example having a different inter-blade spacing or different tube diameters T.

Referring to Figure 4B, it can be seen that according to a variant the front part 3 is not formed by a solid part, but is rather in the form of a solid disc which would have been hollowed out. inside from one of its faces while retaining a solid central portion 30, recess 31 in which are circular ribs 32, two in the example shown, one of larger diameter than the other, and straight ribs 33, eight in the example shown, extending in a star from the solid central portion 30 to the outer edge of the front piece. In this variant, the bearing face is formed by the free edges of the ribs 32, 33 and no longer by a continuous surface. As can be seen, it is also possible to provide steps, which are simply obtained by varying the height of the different ribs 32, 33 so as to form a zone of greater height and two lateral zones of smaller height so similar to Figure 4A.

Referring now to Figure 5, it can be seen that the attachment face 12 has a curved central groove 16 whose role will be explained below.

The front piece 3 also has a through hole 17, opening at the center of the first central portion 13 of the bearing face 11 as can be seen in Figure 4A or 4B and opening at the center of the attachment face 12 as one can see it in Figure 5.

The device 1 further comprises means 4 for securing the rear part 2 to the front part 3. The securing means 4 comprise a screw 18 and a nut 19. The screw 18 is configured to be received in the through hole 9 of the rear piece 2 and in the through hole 17 of the front piece 3, as can be seen in Figure 6. The screw head 20 is received at the end 21 of the through hole 17 opening to the fixing face 12 of the front piece 3. The nut 19 is fixed by any appropriate means in the housing 10 of the rear piece 2, for example by gluing.

The device 1 further comprises means for locking in rotation 22. The rotational locking means 22 consist of the end 21 of the through hole 17 opening on the fixing face side 12, of hexagonal shape, the screw head 20 of hexagonal type of the screw 18 is then kept locked in rotation at the end 21.

Referring to Figure 7, it can be seen that there is shown the device 1 equipped with a mirror-type accessory and mounted on a radiator R with blades L. The accessory comprises a mirror M and an arcuate metal band B by which it is fixed to the device 1. The metal strip B is received in the central groove 16 of the attachment face 12 of the front piece 3 and fixed to the device 1 by inserting the screw 18 in a hole previously provided in the metal strip B. Here, the metal strip B is thus fixed by clamping between the head of the screw 18 and the attachment face 12.

As previously indicated, in the case of bathroom accessories commonly encountered in commerce, they are equipped with fastening means, for example by screwing into a wall. Such fastening means are thus compatible with a fastening device 1 according to the present invention as shown in Figure 8, which shows the device 1 equipped with a cup holder type accessory and mounted on a tube radiator T.

To mount the device 1 on a radiator R, the screw 18 is passed through the through hole 17 of the front piece 3 until the head of the screw 18 is locked in the end 21 of the through hole 17 at the end. 12. The front piece 3 is then placed on the front side of the radiator R so that the first central portion 13 is between the two adjacent blades or tubes T T previous. The rear part 2 is then screwed onto the free end of the screw 18, which is inserted into the through hole 9 of the rear part 2 and then into the nut 19 by rotation of the rear part 2. The rear part 2 is screwed until the bearing face 5 bears against the blades L or tubes T, so that the latter are sandwiched between the rear parts 2 and before 3. It is easy to understand the interest that takes place l use of a rear part 2 truncated cone of revolution, since it can, as indicated above, adapt to different spacings of blades L or tubes T, because it has a cross section of diameter increasing. The accessory may be attached to the front part 3 before or after it has been assembled to the rear part 2 as described above.

In the case of a mirror, as illustrated in Figure 7, we can use the screw 18 to both fix the front piece 3 to the back piece 3 and fix the mirror to the front piece 3. To do this, it simply place the front piece 3 against the front side of the radiator R as before, then place the band B in the central groove 16, then pass the screw 18 through the corresponding hole of the band B and the through hole 17 until the head of the screw 18 bears on the outer face of the band B of the mirror. The rear piece 2 is then screwed onto the screw 18, while holding the head of the screw 18 against the band B with the hand, so that once the rear piece 2 bears against the rear side of the radiator R, the piece before 3 and therefore the mirror M are fixed in position.

It is emphasized here that the accessory will be fixed fixedly in rotation, because steps of the bearing face 11 will bear against the blades L or T tubes and will therefore oppose rotation of the piece before 3 , and therefore the accessory.

It is understood that the above embodiment of the present invention has been given as an indication and not limitation and that modifications may be made without departing from the scope of the present invention.
