Description

The invention relates to a clothes hanger with a hanger body designed as a hollow profile, to which a hanging hook is attached, and with two tension arms inserted into the hanger body, displaceable relative to it, each of which is under the action of a spring element urging it outwards against a limit stop.

Such hangers are known as so-called tensioners and are used in particular for hanging up skirts and similar items of clothing by inserting them into the waistband of the skirt. The tension arms, which are pre-tensioned outwards, rest on the waistband of the skirt from the inside and stretch it open.

0 Such a coat hanger usually has a central hanger body, in the central axis of which a hanging hook is attached. The hanger body is usually designed as a hollow profile, for example as a U-profile that is open at the bottom, into which the tension arms are inserted from opposite sides. The tension arms are guided so that they can move in the hollow profile

and a limit stop prevents the clamping arms from being pushed or pulled out of the bracket body excessively. A spring element, such as a spiral spring or an endless rubber band, etc., is arranged inside the bracket body, which forces the clamping arms into their outwardly protruding limit position, in which they protrude as far as possible from the bracket body and rest against the limit stop.

When using a spiral spring as a spring element, it usually extends in the lengthwise direction of the clothes hanger and rests at its inner end on a crossbar of the hanger body and at its outer end on the inner face of the tensioning arm. When fully retracted, the spiral spring still takes up a relatively large amount of space that is not available for the tensioning movement of the tensioning arm. Furthermore, when the tensioning arm is extended, the spiral spring has only a relatively small

Spring tension so that a spring force sufficient to stretch the garment is only achieved after a certain initial displacement of the tensioning arm.
25

Essentially the same conditions apply when using an endless rubber band as a spring element. The rubber band is guided over hooks which are formed on the tensioning arm on the one hand and on the hanger body on the other. When the tensioning arms are extended, the rubber band has its lowest tension. Even in this state, however, the rubber band must have sufficient tension to prevent it from slipping off the hooks. Thus, between

There must be a minimum distance between the inner end of the tension arm and the end of the hanger body, i.e. the preferred attachment points for the elastic band, which ensures that the elastic band is sufficiently tensioned. In all cases, the span that can be covered by the tension arms of a hanger is relatively small, so that a large number of tension hangers of different lengths must be kept in stock to stretch skirts of standard sizes, which is disadvantageous both in terms of production and in terms of storing the hangers.

The invention is based on the object of creating a clothes hanger of the type mentioned, the tensioning arms of which have a large tensioning path.

This object is achieved according to the invention in that each clamping arm has an eccentrically arranged extension section extending in the longitudinal direction of the clamping arm at the inner end of its clamping arm body, the extension sections of the two clamping arms being arranged in such a way that they run past each other during the clamping movement of the clamping arms, and that the spring element is held on the one hand on the bracket body 5 and on the other hand on the extension section of the clamping arm.

Due to the fact that one end of the spring element is held on the extension section, a relatively high spring tension can be ensured for the tensioning arm 0 even in its outer end position, so that items of clothing can be securely tensioned even with small tensioning arm movements.

A significant advantage of the clothes hanger according to the invention is that the extension sections move past each other during the tensioning movement of the tensioning arms. In this way, the inner fastening point of the spring element arranged on the extension section is displaced into the half of the hanger body assigned to the other tensioning arm during the inward movement of the tensioning arm. The tensioning movement is thus essentially only limited by the dimensions of the tensioning arm and not by the arrangement of the spring element. As a result, the clothes hanger according to the invention can cover a very large span range, which means that a large number of different sizes of clothing can be securely clamped with one clothes hanger.

In order that the clamping arms, i.e. the clamping arm bodies and their extension sections, can move past each other during the clamping movement without hindering each other, and in order to be able to accommodate the spring elements without mutual interference, a preferred embodiment of the invention provides that the clamping arm body and/or the extension section has a C-shaped cross-section. The clamping arm bodies and the extension sections of the clamping arms should each be arranged with the open sides of their C-profiles facing the center plane of the bracket body, i.e. facing each other. In this way, a gap is formed between the webs of the C-profiles of the two clamping arms, in which the spring elements can be arranged and accommodated.

For reasons of good guidance, the C-profile of the

—&Kgr;· -

The width of the legs or flanges of the C-profile of the extension sections can correspond to half the width of the hollow profile of the bracket body, i.e. the web height of the C-profile corresponds to the height of the hollow profile, while the flange or apex width of the C-profile corresponds to the width of the hollow profile. However, so that the extension sections of the clamping arms can run past one another, they must be smaller. In a preferred embodiment of the invention, it is provided that the web of the clamping arm body and the web of the extension section merge smoothly into one another, although the height of the extension section or its web height is less than the height of the clamping arm body. The width of the legs or flanges of the C-profile of the extension sections can correspond to half the width of the hollow profile of the bracket body, whereby they are in contact with one another and can support one another. However, the leg or flange width can also be less than half the width of the hollow profile of the bracket body. According to the invention, the cross-section of the extension section is designed in such a way that the extension section of one clamping arm can enter the cross-section of the clamping arm body of the other clamping arm during the inward clamping movement, where it is guided through it if necessary.

The length of the clamping arm body is essentially half the length of the bracket body, so that the clamping arm bodies of both clamping arms can be completely pushed into the bracket body. The extension sections should be as long as possible in order to be able to cover a large span range, on the other hand, their length is

limited by the dimensions of the bracket body, since they must not protrude from the bracket body when inserted. According to the invention, it is therefore preferably provided that the length of the extension section corresponds to approximately half the length of the bracket body.

The spring element can be either an elastic band or a spiral spring. The spring element engages with its inner end on the extension section of the tensioning arm. For this purpose, for example, a hook for hanging the spring element can be provided on the inside of the web of the C-profile of the extension section. The spring element is held with its outer end on the bracket body, preferably in its end area, i.e. at or near the free end of the bracket body.

In a preferred embodiment of the invention, it can be provided that the spring elements of the two clamping arms are offset in height from one another, so that they pass over one another during the clamping movement of the clamping arms. This is particularly useful when using spiral springs, since the cross section of the spiral spring can be adapted to the distance between the legs of the U-profile of the bracket body, which guides the spring.

The bracket body can have a completely closed hollow profile or a U-profile that is open at the bottom, the latter being more advantageous in terms of manufacturing technology.

However, in this case, for reasons of stability, the legs of the U-profile should be connected to each other at the ends of the bracket body via a crossbar. In this way, it is possible for the

Crossbar forms the limit stop which defines the outer clamping position of the clamping arm and against which a projection formed on the underside of the clamping arm strikes.

In order to adequately guide the clamping arms during the clamping movement, in a preferred embodiment of the invention, a corresponding guide device can be provided on the bracket body. It has proven useful to provide this in the area of the ends of the bracket body. The guide device can preferably have a projection arranged on the inside of a leg of the bracket body, which forms guide spaces with the bracket body for the clamping arm. The projection, which can be designed as an inwardly projecting cross-sectional reinforcement of a leg of the U-profile of the bracket body, has a lower height than the bracket body. This can ensure that a gap is formed between the upper edge of the projection and the base of the U-profile on the one hand and between the underside of the projection and the crossbar on the other hand, the width of which essentially corresponds to the thickness of the legs of the C-profile of the clamping arm body. The gaps thus form guide passages for the C-profile of the clamping arm body.

Particularly in the case of relatively long bracket bodies, a further development of the invention can provide that the legs of the U-profile are connected to one another in the middle area of the bracket body via a rib. The rib can serve as a stop in the fully retracted position of the clamping arms, for example by the projection formed on the underside of the clamping arm running against the rib.

12.

Figures 1 and 2 show a hanger body 12 of a clothes hanger according to the invention. The hanger body 12 has a U-profile that is open at the bottom in cross section and is provided on its upper side in the middle area with a projection 19 on which a hanging hook

11 is secured in a known manner. 25

The two legs 13 of the U-profile of the bracket body

12 are connected to one another at their free end in the middle area of the bracket body via a molded-on rib 14. At the free ends of the bracket body 12, the legs 13 are also connected to one another via crosspieces 15, so that closed profiles are provided in the end areas of the bracket body, as shown in particular in Figure 2.

At the ends of the bracket body, on the inside of each leg 13 of the U-profile, an inwardly directed projection 16 in the form of a cross-sectional reinforcement is formed, which has a hook 17 for hooking in a spring element. The height of the cross-sectional reinforcement 16 is less than the height of the leg 13, so that gaps 18 are formed both above and below the cross-sectional reinforcement 16, which serve to guide a C-shaped clamping arm.

A corresponding clamping arm 20 is shown in Figures 3 to 6. The clamping arm has a clamping arm body 22, on the right end of which, as shown in Figure 3, a clamping runner 21 with a skirt hook 25 is formed. The clamping arm body 22 has a substantially C-shaped cross section (Figure 4) with a web 22b and two legs or flanges 22a.

0 At the left end of the clamping arm body 22 according to Figure 3, a projection 26 serving as a stop is formed on the underside of the lower leg 22a.

An extension section 23, which also has a C-shaped cross-section (Figure 5) is connected to the inner end of the clamping arm body 22, i.e. the left end according to Figure 3. The extension section 23 has a web 23b and two legs 23a. The height of the extension section 23 corresponds essentially to the distance between the inner sides of the legs 22a of the clamping arm body 22. The clamping arm body 22 and the extension section 23 are formed in one piece with one another, with the webs 22b and 23b merging smoothly into one another, as shown in Figure 5.

6. The legs 23a of the extension section 23 are extended to the outer end of the clamping arm body 22 for stability reasons. A hook 24 for hanging a spring element is formed in the web 23b of the extension section 23.

Figures 7 and 8 show a clothes hanger 10 according to the invention, in which two tensioning arms 20 are inserted from opposite sides into the hanger body according to Figures 1 and 2. A rubber band 30 is stretched between each of the hooks 17 at the ends of the hanger body 12 and the hook 24 on the extension section 23 of the associated tensioning arm 20, which serves as a spring element and applies an outward spring force to the tensioning arm 20. In the outer tensioning position of the tensioning arms 20 shown in Figure 7, each tensioning arm rests on the crosspiece 15 of the hanger body via its projection 26 formed on the underside of the tensioning arm body 22, whereby the outer tensioning position is defined.

As can be seen in particular from Figure 7, the hooks 17 and 24 are not at the same height, but are offset in height from one another. This ensures that the left rubber band 3 0 according to Figure 7 runs above the right rubber band 3 0 according to Figure 7, so that the rubber bands run past one another during the tensioning movement of the tensioning arms.

0 Figure 8 shows that the clamping arms 2 0 are inserted into the bracket body in such a way that the open sides of their C-profiles point to the center plane of the bracket body or face each other. Since the extension sections 2 3 are arranged off-center, they can be

When the clamping arms 20 are inserted, they run past each other without hindering the clamping movement. As shown in Figure 8, the extension sections 23 are of such a length that they overlap in the middle area of the clamping body even in the outer position of the clamping arms, in which they protrude as far as possible from the bracket body, and in this way support each other.

Figures 9 and 10 show a representation corresponding to Figures 7 and 8, but the tensioning arms 20 are displaced by a certain amount due to an inward-directed force (not shown) acting from the outside. Figure 9 shows in particular how the rubber bands 30 run past one another without hindering one another due to the offset of the hooks 17 and 24 assigned to them. A further inward-directed movement of the tensioning arms 20 leads to the extension section 23 dipping into the cross-section of the tensioning arm body 22 of the other tensioning arm and being displaced therein to the end of the bracket body 12. Figure 11 shows a tensioning arm in its position completely pushed into the bracket body 12, whereby only one tensioning arm is shown for reasons of clarity. As can be seen from the illustration, the inner position is defined by the stop of the projection 26 on the middle rib 14 of the bracket body. The tension arm body 22 is located almost completely 0 in the right half of the bracket body according to Figure 11, while its extension section 23 extends into the other half of the bracket body or the tension arm body of the other tension arm located there (not shown). The rubber band is in its

maximum tensile or tension load/'where the tensile force is determined by the arrangement of the hook 2 4 on the extension section 2 3.

Figures 12 and 13 show a further embodiment of a clothes hanger according to the invention, which differs from the above-mentioned embodiment only in that instead of a rubber band, a tension or spiral spring 29 is now used. The spiral spring 29 is hooked on the one hand into a hook 24 on the extension section 23 of the tension arm 20, while its other end is held on a hook 17 near the end cross section of the hanger body 12.

Figure 13 shows a cross-section through a coat hanger with two inserted tension arms, which makes it clear that the springs 29 run one above the other in the space formed between the C-profiles of the extension sections 23 running past one another, which is achieved by the height offset of the hooks 17 and 24.
