Description

The invention relates to household items, in particular to hangers, mainly for trousers.

Known hangers for trousers containing a horizontal rod on which the trousers are suspended beyond their middle by bending them. The disadvantage of such hangers is the insufficient storage (crushing) of trousers. Hangers are known containing a frame with a hook and clothespins for clamping suspended products that are moved along the rod (ed. USSR USSR No. 1709986, class A47G 25/48. There is also a hanger with a hook and clothespins at the ends with the possibility of their movement along inclined sections frame (RF patent №2168924 C1 class A47G 25/48). The disadvantage of these hangers is the incomplete expansion of the products in the stored position and the need to use two clothes pegs that lengthen the process of their use. Known close to the claimed technical essence and the achieved result tattoo design of a trouser hanger, containing two flat plate clamps for clamping suspended products, interconnected by spring wire holders made in the form of a snap-lock (trouser racks ANB301 by Attribute Home Products Limited, UK), Attribute hangers industrially manufactured by China "AHS 381, AHS 391 and" Valiant "32506, Internet. A drawback of the design of such hangers is a change, namely, an increase in the compression force of the clips when clamping products of increasing thickness (including 2 trousers at the same time) ), Which may be the cause of insufficient quality preservation of suspended articles (crushing, zasvetlenie individual tissue sections). Damage to the hanger is also possible when clamping thick products. It should also be noted that their use is not convenient enough, consisting in the need to manually open the clamps when placing the trousers between them when hanging them and then holding the closed clamps and trousers not fixed in the working position with one hand, which is inconvenient (the second hand manipulates the hook at this time, clamping the product ) and requires additional time. It is also more convenient to remove trousers when manually pressed apart, which also takes time. The disadvantages of such designs include the insufficient clamping quality of thin products, such as sheets of paper.

The prototypes of the proposed design of the hanger is a hanger (RF patent of the author of this application No. 2458615 class A47G 25/48 publ. 08/20/2012) and a hanger also of the author of this application (patent RU 2511817 C2 class A47G 25/48), containing (see FIG. . 1, 2) two flat plate clamps 1, a hook for hanging the hangers 2, two clamp holders 3 and a retainer 4, which hold the clamps in a compressed working state and in the open state when placed between the clamps of the suspended trousers. The clamp holders 3 are made of a spring wire in the form of an L-shaped element with two vertical branches, the lower ends fixed motionless in different clamps and passing above through the bends 5 into two horizontal branches, which end with a common bend. The ends of the horizontal branches are superimposed on each other by bends, forming a hole for fixing the lower end of the hook in it with the possibility of rotation of the hook around the vertical axis. The latch is made of a spring wire in the form of two triangular elements 6 at the ends connected by a common wire and covering pairwise vertical branches of different holders, while the size between the vertices of the triangular elements C of the latch (Fig. 2) is smaller than the size Ε between the vertical branches of the holders, and the free ends the latch 12 (Fig. 3) is bent upward relative to the horizontal branches of the holders. The latch has the ability to move along the vertical branches of the holders, while in the upper position of the latch, the holders and clamps are apart to accommodate the last suspended product, and in the lower position of the latch clamps are closed, compressing and holding the product in suspension due to friction between the holders and the latch. The compression force of the clamps is ensured by and within the elastic deformation of the clamp holders and the clamp, which can move along the vertical branches of the holders, which ensures a constant and sufficient clamping force to hold the suspended products of different thicknesses and, if necessary, an adjustable compression force (for example, for soft easily deformed products).

This design of the hanger allows you to suspend products of various thicknesses, is convenient to maintain and does not require significant effort when clamping the product.

The disadvantages of this design of the hanger identified during the testing of prototypes of the hanger are:

1) the non-parallel combination of the working planes of the clamps during their compression, which may be the reason for insufficient quality preservation of the suspended products - local crushing of the product by the upper edges of the clamps. This drawback occurs with the vertical installation of the branches of the 3 holders in the clamps 1. In this case, when the clamp moves down and the clamps are aligned, they first touch each other with the upper edges 8. This is explained by the design features of the hanger, which consists in the fact that when the clamp moves down and the beginning the compression of the clamps, the size between the lower ends of the vertical branches of the holders for the normal operation of the hanger (the compression process and automatic opening of the clamps by moving the latch up) should be larger than the size Ep between their upper ends, both in the presence of between the clamps of the suspended product, and without it. With further movement of the latch down, the compression force of the vertical branches of the holders increases and, accordingly, the magnitude of their elastic deformation and simultaneously the non-parallelism of the working planes of the holders increase, which leads to local compression of the clamps and to local creasing of the suspended products;

2) a limited distance between the ends of the unclamped clamps, which may not be convenient enough to be placed between the clamps of the trousers when hanging them, especially with a large thickness of the trousers;

3) the sleeve with which the hook is fixed in the hole of the upper branches of the holders has a cylindrical shape and its outer diameter is larger than the diameter of the hole of the holders, which makes it difficult to insert a sleeve with a hook into the hole of the holders;

4) the implementation of the holders and the clamp of the spring wire without additional processing of its surface does not provide a sufficiently soft and smooth movement of the clamp on the holders,

The technical task of the invention is the creation of a new design of the hanger with plate clamps, mainly for trousers, providing better preservation of the suspended products, more comfortable and easier maintenance and easier assembly of the hanger.

The problem is solved in the design of the hanger (Fig. 1), containing two flat plate clamps 1 with bevels 10 at the ends of the working surfaces of the clamps over their entire height; a hook for hanging the hanger 2 with a sleeve 7 (Fig. 3, 4a) at the bottom of the hook having a tapered lower end 9 (Fig. 4), two clamp holders 3 and a clamp 4 holding the clamps in a compressed working position and in the open state when placed between clamps of the suspended product. The clamp holders 3 are made of a spring wire in the form of a L-shaped element with two vertical branches, the lower ends fixed motionless in different clamps and passing above through the bends 5 into two horizontal branches 11 ending in a common bend. The vertical branches of the holders 3 are installed with an inclination towards the middle of the hanger so that when the clamps begin to compress and close their lower edges (Fig. 3), the angle α between the working surfaces of the clamps is at least 2-3 degrees. The ends of the horizontal branches of the holders overlap each other, forming a hole for fixing the lower end of the hook with the sleeve 7 with a tapered lower end (figure 4) with the possibility of rotation around a vertical axis. The latch 4 is made of a spring wire in the form of two triangular elements 6 with bent free ends 12 (Fig. 3) upward relative to the horizontal branches of the holders. The latch can move along the vertical branches of the holders, while in the upper position of the latch clamps are automatically open to place a suspended product between them, and in the lower position are closed, compressing and holding the product in suspension through the clamps 1. The triangular elements 6 of the latch are connected by a common wire and cover pairwise vertical branches of the holders, while the size C between the vertices of the triangular elements of the retainer (Fig. 2) is less than the size Ε between the vertical branches of the holders. The latch 4 and the holders 3 are coated with a layer of galvanic nickel or chromium.

The execution of the hanger with holders, the vertical branches of which are inclined to the working surfaces of the clamps towards the middle of the hanger with the angle α between the working surfaces of the clamps when they touch the lower edges, ensures parallelism of the working surfaces of the clamps when clamping suspended products and their high-quality preservation in suspension. This is achieved due to the fact that when the clamp moves down and the compression of the suspended product begins, the clamps begin to compress the product with the lower edges of the working surfaces, and when a certain compressive force of the clamps and the clamp pressure reach the vertical branches of the holders, they undergo elastic deformation with simultaneous rotation of the clamps by the angle α (Fig. 3) and parallel installation of their working surfaces 1A. (The angle α depends on the specific design of the hanger — the dimensions and material of the holders and the clamp, the size of the clamps, etc.). With the clamp moving further downward, the clamps are compressed by the parallel surfaces of the clamps and the greatest force is achieved on the clamps, sufficient to hold the suspended product, with this force attached to the clamp and clamps, reaches the limit sufficient for reliable fastening of the product and is felt by the operator through the clamp. The achievement of a tangible limit of compression of the product and the force on the clamp is explained by a significant increase in resistance at the end of compression of the product due to the increasing density of the compressible material and the larger area of the working surfaces of the clamps compared to the edge area of the clamps. Increasing the force on the lock also contributes to the increasing elastic resistance of the branches of the holders. The implementation of the holders and the latch with galvanic nickel or chrome plating, as established experimentally, makes the work of the hanger smooth, easy and almost silent. The conical end of the sleeve makes it easier to insert the sleeve with a hook into the hole of the horizontal branches of the holders due to the fact that the conical end of the sleeve does not prevent it from being inserted into the hole of the holders due to the smaller diameter of the bottom of the cone compared to the diameter of the hole of the holders. With further alignment of the sleeve with the holders, the cone easily pushes the elastic branches of the holders to its fixed location in the hole.

The implementation of the clamps with developed work surfaces in the form of small recesses or protrusions can improve the reliability of fixing the suspended products and reduce the force of their fixing. And the implementation of clamps, holders and clamps of various materials with their various processing expands the technological capabilities of the manufacture of hangers, can reduce the cost of their manufacture, simplify their maintenance and diversify their design.

This design of the hanger provides reliable and high-quality suspension and preservation of suspended products, significantly increases the ease and convenience of its use and simplifies its assembly due to: 1) installation of the vertical branches of the holders in the clamps with an inclination to their working surfaces towards the middle of the hanger; 2) increase in size between the ends of the clamps; 3) coatings of holders and retainer with nickel or chrome; 4) execution of the sleeve of the hook with a tapered lower end. The manufacture of hanger parts from various materials expands the technological capabilities of its manufacture and consumer qualities.

A comparative analysis of the claimed design and analogues reveals the presence of significant distinguishing features of the claimed design in comparison with the closest analogues, which allows us to conclude that the proposed solution meets the criterion of "novelty."

The presence of distinctive features makes it possible to obtain a positive technical result, expressed in the creation of a new, more advanced design of the hanger, providing more convenient and easy maintenance, high-quality preservation of suspended products and its easier assembly.

The proposed hanger design is shown in FIG. 1, which shows a general view of the hanger.
