Abstract

FIELD: personal and household items.

SUBSTANCE: hanger that contains two flat plate-like clamps, a hook for mounting the hanger, two clamp holders and a retainer for holding the clamps in a compressed state and for unlocking the clamps. Grip holders are made out of wire spring in the form of an L-shaped element with two vertical branches, fixed with their lower ends in different grips. Vertical branches bend and become horizontal, having common bends at the ends, superimposed on each other with the formation of a hole for placing the lower end of the hook in it. Retainer is made of a spring wire in the shape of two triangular elements at the ends, connected by a common wire and covering pairs of vertical branches of the holders, wherein the distance between the tops of the triangular elements of the retainer is smaller than the distance between the vertical arms of the holders, and the free ends of the lock are folded upward relative to the horizontal branches of the holders, which ensures that the latch is not tilted when it is moved. Vertical branches of the holders are installed with an inclination to the clamps. At the ends of the working surfaces of the clamps, the bevels are made for more convenient placement of the items to be hanged, and at the bottom of the hook there is a conical bushing that facilitates the assembly of the hanger. Working surfaces of the clamps in their compressed position are parallel and may have protrusions, grooves or soft pads to more reliably hold the suspended products.

EFFECT: hanger is proposed.

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 (13) C1 CL. 7A47G 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 cut a trouser hanger design containing two flat plate clamps for clamping suspended products interconnected by spring wire holders made in the form of a snap-lock (trouser hangers AHB301 from Attribute Home Products Limited, UK), manufactured by China Attribute hangers "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 clamps when clamping products of increasing thickness (including 2 brackets at the same time) k), which may cause 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 the hanger (patent RU 2511817 C2, class A47G of the author of this application}, and the decision of 05.25.2016 to grant a patent for the invention of the “hanger” according to application No. 2015107589/12 (012225) of 02.26.2015 of the author of this application The hanger contains (see Fig. 1, 2, 3, 4) two flat plate clamps 1 with bevels 10 at the ends of their working inner surfaces 8, which can be made developed or have soft gaskets, a retainer 4 and two clamp holders 5 ( Fig. 2), made of spring wire in the form of L-shaped elements with two vert ikalnymi branches 3, fixed by the lower ends in different clamps inclined to the inner working surfaces of the clamps to the side to the middle of the hanger, and the upper ends of the vertical branches of the holders pass through the bends into the horizontal branches 11 (Fig. 1) with common bends at the ends that overlap each other each other with the formation of an opening for accommodating a sleeve 9 (Fig. 4) with a tapered lower end and a hook 2 with the possibility of rotation, and the latch 4 is made of a spring wire in the form of two triangular elements 6 at the ends, GOVERNMENTAL common wire and a dimension between the vertices of the triangular elements having a smaller size between the vertical branches holders E (FIG. 2), while the triangular elements of the retainer have free ends 7 bent upwards (Fig. 3) relative to the horizontal branches of the holders and cover pairwise vertical branches of the clamp holders with the possibility of moving the clamp along them and fixing them together with the clamps in any working position due to friction between clamp and holders, while in the upper position of the clamp, the clamps are apart for placement between the last suspended products, and in the lower position of the clamp, the clamps are compressed with a parallel position of their work their surfaces, gripping and holding the item in a suspended state due to friction forces between the holder and the retainer. The compression force of the clamps is ensured by and within the elastic deformation of the clamp holders and the clamp when moving along the vertical branches of the holders, which ensures a constant and sufficient clamping force to hold the clamps of suspended products of different thicknesses, and also, if necessary, adjustable compression force (for example, for soft easily deformed products). In this case, the vertical branches of the holders are installed with an inclination to the inner working surfaces of the clamps towards the middle of the hanger in such a way that, with the clamp position intermediate in height of the holders, ensuring that the clamps touch the lower edges of the inner working surfaces relative to each other, there is an angle of at least 2 between the working surfaces of the clamps -3 degrees, and with the lower position of the clamp, the working surfaces of the clamps are parallel compressed. Clamps, holders and clamps can be made of various materials with or without coating.

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 prototype hanger, are: 1) Uncontrolled by the magnitude of the inclination of the vertical branches of the holders towards the longitudinal axis of the hanger and from its middle when the latch moves down and clamps the suspended product. This drawback occurs with the vertical installation of the holder branches in the clamps, which may be the reason for their insufficiently reliable fixation in the lower working position of the clamps and, accordingly, insufficient clamping and holding of the suspended product. With this installation of the holders without tilting their vertical branches in the clamps in the direction of the longitudinal axis of the hanger to the side from its middle and, accordingly, without creating pressure of the upper branches of the holders on the triangular elements of the retainer, with the subsequent movement of the retainer down, it presses with triangular elements on the vertical branches of the holders and their inclination to the middle of the hanger along its longitudinal axis, while the vector of friction forces between the retainer and the vertical branches of the holders changes direction from vertical to with the advent of horizontal components of the friction forces, differing in magnitude for each pair of "holder-retainer" due to different pressure forces on different ends of the retainer with your fingers. Such a change in the friction forces creates conditions for the unstable holding of the lock in the lower position when it is released. This occurs due to the horizontal shift of the retainer after it is released from the pressure of the hands due to the difference in the magnitude of the horizontal components of the friction forces and the decrease in the vertical components of the friction forces, which changes the structure of the friction forces from static static friction to friction movement towards their decrease. In this case, the vertical components of the elastic pressure forces of the vertical branches of the holders on the retainer overcome the friction forces and shift the retainer to the upper position. The above considerations are confirmed experimentally, when the latch, when released from pressure by the fingers, is unreliably fixed in the lower position and moves up.

The technical task of the invention is the creation of a new design of a hanger with plate clamps mainly for trousers, providing increased reliability of its work and better clamping and retention of suspended products.

The problem is solved in the design of the hanger (Fig. 1, 2, 3, 4), containing two flat plate clamps 1 with bevels 10 at the ends of their working surfaces 8, which can be made developed or have soft pads; the clamp 4 and two clamp holders 5 (Fig. 2), made of spring wire in the form of L-shaped elements with two vertical branches 3 (Fig. 1, 5), fixed by the lower ends in different clamps inclined to the inner working surfaces of the clamps to the side to the middle of the hanger with an angle α between the working surfaces of the clamps at the beginning of their compression of at least 2-3 degrees (Fig. 3) and the parallel position of the working surfaces of the clamps at the end of their compression. The upper ends of the vertical branches of the holders pass through the bends into the horizontal branches 11 (Fig. 1) with common bends at the ends that overlap each other with the formation of an opening to accommodate a sleeve 9 with a tapered lower end (Fig. 3, 4) and a hook 2 with the possibility of rotation. The latch 4 is made of a spring wire in the form of two triangular elements 6 at the ends connected by a common wire and with a size between the vertices of the triangular elements C (Fig. 2) smaller than the size between the vertical branches of the holders E. The triangular elements of the latch have bent upwards 7 free ends (Fig. .3) and cover in pairs the vertical branches of the clamp holders with the possibility of moving the clamp along them and securing them together with the clamps in any working position due to the friction forces between the clamp and the holders, while in rhnem position retainer clamps and vertical branches holders apart to accommodate therebetween the suspended articles, and compressed at a lower position latch. The latch, the vertical branches of the holders and the hook can be coated with nickel, chrome or other materials. A distinctive feature of the proposed hanger is the installation of vertical branches of the holders in the clamps with an inclination in the direction of the longitudinal axis of the hanger away from the middle of the hanger in such a way that they maintain a perpendicular position to the longitudinal axis of the hanger for any vertical position of the latch. In this case, the holders are installed in the clamps with an angle of β (Fig. 5) of their vertical branches in the direction of the longitudinal axis of the hanger before installing the latch, and after installing the latch in the upper position, the vertical branches of the holders take a position perpendicular to the longitudinal axis of the hanger this creates a certain pressure of the upper ends of the holders on the triangular elements of the latch away from the middle of the hanger in the direction of its longitudinal axis. This pressure is ensured by the design of the hanger, in which the vertical branches of the holders due to their elastic properties are in a perpendicular position to the longitudinal axis of the hanger and at the same time in an inclined position relative to the clamps (Fig. 5). When the latch moves down and clamps the suspended product, the latch pressure gradually increases on the vertical branches of the holders in the direction toward the middle of the hanger due to compression of the extended vertical branches of the holders by the inner surfaces G of the latch (Fig. 2). The pressure reaches its maximum value during the clamping of the product and, due to the selection of the structural elements of the hanger, is balanced with the pressure of the vertical branches of the holders on the clamp previously created by inclining the vertical branches of the holders in the clamps, which ensures that the vertical branches of the holders are kept in a position close to perpendicular to the longitudinal the axis of the hanger and, accordingly, reliable retention of the latch and the suspended product in a stationary position due to the provision of the vertical direction of the vector of friction forces between the vertical branches of the holders and the retainer and, accordingly, the static static friction between them.

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 by installing vertical branches of the holders in the clamps with an inclination in the direction of the longitudinal axis away from the middle of the hanger and, accordingly, increasing the reliability of its operation and the quality of the clamp suspended products.

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, which ensures its more reliable operation and better fixing of suspended products.

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

The hanger contains two flat plate clamps 1 with bevels 10 at the ends of the working planes 8 clamps 1, a hook 2 for hanging the hangers, two clamp holders 3, made in the form of L-shaped elements with two vertical branches 3, fixed with the lower ends in different clamps with an inclination to them towards the middle of the hanger and passing through bends into horizontal branches 11, having common bends at the ends with the formation of an opening for placement of a sleeve 9 with a tapered lower end and a hook with the possibility of rotation, and a latch 4 with triangular elements 6 at the ends with the free ends 7 bent upward and enclosing the vertical branches of the holders with triangular elements in pairs with the possibility of moving it up and down along them with fixing clamps in any working position. The size C between the vertices of the triangular elements of the retainer is smaller than the size E between the vertical branches of the holders. In the upper position of the clamp, the vertical branches of the holders and clamps are apart, and in the lower position of the clamp, the clamps are compressed, holding the suspended product. The vertical branches of the holders are installed in the clamps with an inclination in the direction of the longitudinal axis of the hanger away from its middle so that they remain perpendicular to the longitudinal axis of the hanger at any position of the latch. The holders and retainer are coated with a layer of nickel or chrome. The working surfaces of 8 clamps 1 in the lower position of the latch are parallel and can have a developed surface or soft gaskets.

In FIG. 2 shows a view A of FIG. one.
