FR2473949A1 - Injection moulded plastic coat hangers partly over-moulded with rubber - for broad, colourful hangers with non:slip-surfaces - Google Patents

Abstract

Coathangers are moulded in two stages by first injection moulding a basic triangular structure, with a supporting hook and opt. ancillary strap hooks, from a rigid plastic moulding matl., and then overmoulding parts of the plastic structure with a rubbery material offering a relatively high coefficient of friction. The superficial shapes of the basic moulding, or holes therein, provide a more positive key for the overmoulded coatings than conventional designs involving dip-coating of wire frames, esp. where broad supporting surfaces are reqd. Opt. the core frame and the rubber coatings are of contrasting colours.

Description

 The subject of the present invention is a method of manufacturing hangers for hanging clothes and the like, and the hangers obtained according to the method.

 The invention relates to the technical sector of hangers and similar supports for the suspension and storage of clothing.

 One of the aims sought according to the invention ex the realization of a hanger having anti-slip properties while giving it a new aesthetic by the implementation of an original manufacturing process.

 Currently, it is known to produce hangers having anti-slip properties. These generally consist of a profiled metal frame which is dipped in a bath of plastic material, in particular flexible P.V.C. in order to completely cover it.

 Illustrated in Figures 1 and 2 is a hanger made according to the above technique. In the illustrated embodiment, the metal frame a has a U-shaped section 11a in the form of a sector; inside the latter is attached and fixed by welding 2, l1extre # ity 13 of the lower part 12 pants hanger. The lower part 12 is profiled to form in 14 the spouts intended to retain in suspension the loops formed on certain garments. The frame thus produced is then dipped in a plastic bath to obtain a coating 3.

 The aforementioned technique has many disadvantages due to the large number of manufacturing phases for an ordinary hanger such as that illustrated, a high cost price. We also observe the uniformity of presentation of the hangers obtained.

 According to the invention, the manufacturing process is simpler and therefore less lumpy and offers great diversity in the aesthetic presentation of the hanger obtained.

 According to a first characteristic, the method of manufacturing hangers is remarkable in that in a first phase, the hangers, of any desired shape, are obtained entirely by injection of rigid plastic material and have means allowing the attachment of a subsequent coating, in a second phase, a flexible or semi-ridged material of the rubber type is injected by overmolding on all or part of the surface of the hanger, the maintenance and adhesion of this second layer relative to the preformed hanger being obtained by insertion of overmoulding material on the attachment means formed during the first manufacturing phase.

 According to another characteristic, the hangers are shaped into a rigid plastic material according to the desired shapes and receive a rubber-type coating by overmolding on all or part of their profile.

 According to another characteristic, the hangers are composed of a frame of rigid plastic material and of at least one overmolded plastic coating, of different encoders.

 These characteristics and others will become apparent from the following description.

To properly fix the object of the invention to the figures of the accompanying drawing
Figure 1 is a half view of a hanger made according to the conventional method, with a partial section illustrating the structure of the hanger.

 Figure 2 is a sectional view along line II-II of Figure 1.

 Figure 3 is a view illustrating a hanger obtained according to the manufacturing method of the invention with an embodiment of non-limiting form.

 Figure 4 is a partial sectional view illustrating a first variant of maintaining the overmolded coating on the plastic frame of the hanger.

 Figures 5 and 6 are sectional side views illustrating other variants of maintenance.

 Figure 7 is a front view illustrating another method of holding.

 In order to make the object of the invention more concrete, it is now described in a nonlimiting manner illustrated in the figures of the drawing.

In Figure 3, there is illustrated a hanger 4 obtained according to the manufacturing process. The illustrated form is given by way of example and is in no way limiting. The hanger 4 is produced from the injection of a rigid plastic material according to a preset profile 5. As illustrated in Figure 3, the hanger obtained has a hook forming part 51 extending downward in a flared shape from two extensions 52 whose lower ends curved 53 and connected to each other to form a lower horizontal branch 54, thus defining an isosceles triangulation. In addition, horizontal arms 55 are established inside the plane of the hanger and are curved at 56. In the upper part of the hanger, under the hook, is provided a profiled opening 57 defining in its part lower horizontal plane
The hanger as described is produced by injection of rigid plastic.

 According to the method, a second manufacturing phase is carried out by overmolding an external coating 6 over all or part of the profile of the preset hanger. This coating 6 can advantageously be a material of the rubbery type having anti-slip qualities.

 To ensure the retention of the overmolded coating on the pre-established hanger made of rigid plastic material, provision was made during the manufacture of the latter for retaining means 7 which cooperate with the overmolded coating.

 As illustrated in the various figures, it may be openings 71 arranged on the parts receiving the coating, FIG. 3. These can also have roughness 72 or pins, FIG. 4. As a variant, the profile of the hanger obtained after the first phase of manufacturing has bulged parts 73 around which the coating is overmolded, Figure 5, or may also have several means combined at the same time, fi g "re 6. The different means can be arranged in variable locations as required.

 Figure 7, another mode of retention has been provided. In this case, after the first manufacturing phase, the hanger has housings 81 in which the covering 9 is adjusted.

 The latter can be done over all or part of the profile of the hanger, whether or not projecting beyond the outside relative to the rigid plastic frame. The coating can be produced in a different color from that of the rigid plastic frame, thus giving a new aesthetic. It is also possible to provide for the hanger to have coatings produced by overmolding in different colors. It suffices to provide different stages of overmolding of the mpropriate parts of the hanger with the use of corresponding covers for the rest of the hanger.

 The advantages appear well and we cite in particular the new manufacturing technique making it possible to obtain a new aesthetic of the hangers. The overmolded coating strengthens the load-bearing parts of the hanger.

 The invention is in no way limited to that of its modes of application any more than to those of the embodiments of its various parts which have been more particularly indicated; on the contrary, it embraces all its variants.
