Body of the support has two rod fixation units that have cylindrical cavities (EVIi, EVIj) opening onto its frontal face (FAF). The cavities present different predetermined sections and respective longitudinal axes parallel to the face (FAA).

Description

The present invention relates to a rod support with multiple means of fixation.

The field of the invention is that of living quarters in which find decorative materials that obscure the windows, such as curtains or curtains, and separating materials fencing shower trays or bathtubs, and opposing splashing water, such as shower curtains. These materials are present in the form of flexible panels of fabrics or plastics, arranged mobile way on rods, usually via hooks or rings. These rods, generally of circular or rectangular section, full or hollow, are positioned on a fixed structure, for example a wall or a partition, via rod supports. These are usually located near the ends of those, often at the ends.

These rod supports are commonly in the form of a metal or plastic body. This body is connected at one end to a plate perpendicular to the axis of the body and provided with screw holes, allowing its fixation on a support surface. This body has at its other end a recess of circular or rectangular section adapted to receive rods, the plane of this recess being perpendicular to the axis of the rod and to the plane of the surface support. The rod can be locked in this recess with a screw of blocking. This screw is supported in a screw hole on the periphery of the recess and in the plane of the latter.

Such carriers have several limitations.

First, they admit exclusively a range of rods of circular or rectangular section, strictly limited in section by that of the recess.

Second, they require the introduction of the rod by threading into bias first in a first support, then by translation then in a second support. This requires having a certain space of on the one hand between the rod and any partitions perpendicular to the support surface and secondly between the rod and the support surface. it also requires some play inside the recesses making it impossible fixing a rod of diameter close to or equal to the nominal diameter of the recess. The space between the rod and the support surface increases the cantilever and therefore weakens the attachment of the support on the support surface.

Thirdly, the locking screw is indispensable and complicates the support structure. In addition, it can damage the surface of a rod by stripe or punching, especially if the latter has a decorative role or if it has a hollow section.

The invention proposes to overcome these various limitations by means of a advanced rod support.

The elements present in several figures are assigned a single and same reference.

Figure 1 shows a rod support. The latter consists of a PLA plate and COR body.

The PLA plate delimited by two parallel planes corresponding to the face FAA back and the PLM middle face is usually discoidal. She can be secured by its FAA back side on a support surface locally coplanar to FAA by gluing or screwing. In the latter case, she is equipped a central screwing hole ORI, or several screw holes.

The COR body is generally cylindrical, delimited by two sections coplanar lines with two parallel planes FAA, PLM. The PLM middle face is common to the COR body and the PLA plate, the COR body being affixed on the PLA plate. In concrete terms, the two volumes of COR and the PLA plate can be molded unitarily and constitute a plastic part unique. This piece has a certain elasticity suitable for interlocking rods.

This COR body has a main AX axis common to the PLA plate and to the screw hole ORI. In order to allow the passage of a screw, it presents a cavity longitudinal axis coaxial with this main axis AX.

The body COR is provided with several means for fixing rods of to be able to receive different types and dimensions of rods.

First, relative to a first attachment means, the body COR present, according to two diametrically opposed generatrices of the cylinder the constituting a first slot FENi over all or part of its height. This slot FENi crosses a first cylindrical recess EVIi of diameter less than or equal to that of the circular section rod can be fixed, this recess is more close to the FAF front face than the PLM center face and the back face. The axis AXEi of this cylindrical recess EVIi is secant and perpendicular to the axis main AX.

When attaching a circular rod in the EVIi recess, as well as shown in Figure 2, it is necessary to secure the support on the surface in such a way that the axis of the recess EVIi is horizontal like that of most of the rods once positioned. Then the fixation is carried out by nesting, by lightly pressing on the rod presented at the end of the FENi slot. The two parts of the COR body delimited by the slot FENi will then bending due to the elasticity of the material constituting the COR body, deformations being minimized because of the presence of this slot FENi on any or part of the height of the body COR. Maximum bending occurs when the rod is introduced into the part of the slot FENi external to the EVIi recess. She decreases when the rod arrives in position in the recess EVIi. If the diameter of the rod is slightly greater than that of the recess EVIi, it remains a residual bending compatible with the elasticity of the material. It should be noted that this the last must work in elastic and non-plastic deformation, otherwise he would suffer permanent deformations or even breaks.

Then, relative to a second fixing means, the COR body can also present a second slot FENj and a second recess EVIj, this last of diameter different from that of the first recess EVIi, and disposed of way that they do not interfere geometrically with the first slot FENi and the first recess EVIi. For reasons of ease of realization and of holding mechanically, the slots FENi, FENj, and the recesses EVIi, EVIj may be perpendicular. The axis AXEj of this second cylindrical recess EVIj is also secant and perpendicular to the main axis AX. In other words, the three axes AX, AXEi and AXEj constitute a right trihedron.

Fixing a circular rod in the second recess EVIj is unfolds in a similar way to the positioning of a circular rod in the first recess EVIi. It is represented in figure 3.

To match the sizes of circular section rods commonly marketed, one of the recesses EVIi, EVIj is adapted to rods of 6 to 8 millimeters in diameter, the other to rods of 9 to 12 mm diameter. It does not matter whether the latter have solid sections or hollow. This means that the nominal diameters of the respective recesses EVIi, EVIj will be of the order of 6 and 9 mm, so as to be able to work the body in flexion.

Then, relative to a third attachment means, the COR body can also present a third slot FENk and a third recess EVIk cuboid. The axis AXEk of this recess EVIk is secant and perpendicular to the main axis AX.

The large median M1k of the section of this third recess EVIk is perpendicular to the generatrices of the cylinder constituting the body COR. this allows to position a rod with rectangular section so that the large median M1k of the section is vertical, which gives it a better module of bending only when the small median M2k of the section is vertical.

The fixing of such a rod is done in a similar way to that of the rods previously presented circular, and is shown in Figure 4.

In order to match a rod gauge with rectangular section widely marketed, this EVIk rectangular recess is suitable for rods of 12 mm by 8 mm, figures corresponding to the dimensions of both medians M1k, M2k.

The third recess EVIk can be indifferently arranged in cooperation with one of the previous recesses, or remain independent of the latter, provided that there is no interference between the different recesses so as to retain sufficient quantities of material to support a positioned rod. In the present embodiment, it preferably cooperates with the second recess EVIj, which assumes less removal of material than in the case of cooperation with the former EVIi recess which has a smaller volume. The third axis AXEk is located then confused with the second axis AXEj.

Similarly, not shown in the figures, it is possible to provide a fourth means of fixing rods in the form of a slot and a parallelepiped recess, the latter being able to be coaxial with one of the previous cylindrical recesses not cooperating with the third means.

According to another type of embodiment, it is possible to provide other fastening means. Of the corresponding recesses, recesses rectangular can be adapted to the fixing of two families of rectangular section or, more generally, rods whose section presents two parallel faces.

By extrapolating from the embodiment shown, it is possible, given the respective dimensions of the body and the recesses made, provide the support with any number of fastening means for rods of any size, these means being individualized or superimposed taking into account geometric limitations prohibiting overlapping similar recesses having different sizes. In particular, it is impossible to foresee two coaxial cylindrical recesses.

Figures 6 and 7 show a hood CAP. This hood allows the locking a rod fixed on the body COR. The CAP cover has a FUT of cylindrical shape and coaxial with the body COR along the main axis AX. It was FUT is delimited by two straight sections coplanar with two parallel planes corresponding to the medial face bis PLM 'and the front face bis FAF'. When setting up of this hood CAP, its was FUT bears on the plate PLA and the planes corresponding to the median PLM and median bis PLM 'merge. The was FUT is closed by a flat bottom corresponding to the frontal face bis FAF '. When placing the CAP cover, its bottom must not bear on the end of the COR body, so that a free interval is provided so that allow accommodation of rods that would exceed the front face FAF without them coming into contact with the frontal face bis FAF '. Similarly, inner diameter of the FUT should exceed the outer diameter of the COR body, this one being dilated at its outer end when fixing a rod.

In order to allow the CAP cover to be adjusted on the COR body, this cover CAP has slots FENi ', FENj' and recesses EVIi ', EVIj', EVIk ' positioned and dimensioned in a similar manner to their counterparts of the COR body, respectively FENi, FENj and EVIi, EVIj, EVIk.

Several slots FENi ', FENj' are thus arranged along generators of the cylinder constituting the cap CAP. Slots FENi ', FENj' meet recesses EVI 1 ', EVI 2', EVI k 'at their opposite ends to those opposite the fixed structure, or close to the plane corresponding to the front face FAF '.

To allow its attachment to the rods by interlocking, CAP hood must have slots FENi ', FENj' of equivalent width to the recesses associated EVIi ', EVIj', EVIk ', the cap CAP itself consists of an elastic material being unfit by its geometry to work in deformation.

In the case where a rod is fitted into a recess EVIi of slightly smaller dimensions, COR body parts located on both sides else of this recess EVIi retain residual elastic flexion and the body COR cylindrical is deformed, this all the more as we move away from the PLA plate. It is therefore necessary to provide a clearance between the outer diameter of the body COR and the inner diameter of the hood CAP.

The CAP cover can be clipped or screwed onto the COR cylindrical body using adequate devices not shown, vis-à-vis, near the median plane PLM. Depending on its conformation, the CAP cover can be clipped or screwed on the PLA plate, then carrier of the aforementioned devices.

Slots FENi, FENi ', FENj, FENj', FENk and recesses EVIi, EVIi ', EVIj, EVIj 'of the body COR and CAP CAP and the axial orifice ORI passage a screw may be in the form of thin solid areas pre-cut and can be removed depending on the fixation to achieve.

The body COR may furthermore present at its recesses EVIi, EVIj, EVIk and with regard to the rods concave to convex reliefs, recessed or in bump, not shown, allowing immobilization in rotation of these rods, and can cooperate with complementary reliefs arranged on the rods.

The embodiments of the invention presented above have been chosen in view of their concrete nature. It would not be possible, however, to list exhaustively all the embodiments covered by this invention. In particular, any means described may be replaced by means equivalent without departing from the scope of the present invention. As precised previously, a large number of combinations of fastening means can be realized within the scope of this invention.
