Description

The utility model relates to the field of vehicles, namely to holders for the hands of standing passengers for installation on support devices in the cabin of vehicles intended for transporting a large number of passengers, for example, buses, trolleybuses, trams, subway trains and other public transport.

A known holder for the hands of passengers with the possibility of placing it on the handrail of a vehicle [1, Patent RU 65988 U1, IPC B60N 3/02 (2006.01), priority 04/18/2007, published 08/27/2007]. It consists of a non-flexible suspension and flexible supporting parts in which cavities are formed. Moreover, in the suspended part - with the possibility of placing passengers' hands in it, and in the supporting part - with the possibility of a supporting device passing through it. In addition, at the bottom of the supporting part there are two through fastening holes, with the possibility of clasping such a bottom with two half-bushings, secured with screws through the mentioned holes.

The disadvantages of the analogue [1] are the complexity of the design of such a holder due to the need to assemble it from separate parts, as well as the use of adhesive joints, which leads to an increase in installation time. There is also no possibility of tightly securing such a holder to the handrail if necessary. The limited service life of the belt, as well as the low vandal resistance of the belt are also disadvantages of such a device.

A simpler and more reliable holder for passengers' hands is known with the possibility of its placement on the handrail of a vehicle [2, Belt 5024 KKT 7001, Article 043.00384, manufacturer faigle Group, www.faigle.com], adopted as a prototype.

It consists of support and suspension parts, in which cavities are formed, and in the support part - with the possibility of a support device passing through it, and in the suspension part - with the possibility of placing the hands of passengers in it. In addition, the support part has a cutout in communication with its cavity and with the cavity of the hanging part, and above and below the cavity of the support part there are through fastening holes, and the one located above is made in an additional clamping device located on top of the support part.

Although the prototype is simpler than its counterpart, however, due to the said clamping device, made of a material different from the material of the main part of the holder, and the presence of two through holes, it is also somewhat complex in its design, manufacturing technology and installation on the handrail of the vehicle interior .

Therefore, both the analogue [1] and the prototype [2] do not significantly ensure the ease of manufacturing of the holder, as well as the ease and speed of their installation on supporting devices, such as handrails, in the vehicle interior.

The purpose of the utility model is to improve reliability.

The technical result is also improved reliability.

The problem is solved and the technical result is achieved in that the holder for the hands of passengers with the possibility of its placement on the handrail of the vehicle, formed by a volumetrically colored monolithic body made of polymer material, and consisting of a supporting part (1) and a hanging part (2) with walls (3 ), located along its vertical axis (01), and in the supporting part (1) a cavity (4) is formed with the possibility of a support device (5) passing through it, and in the suspended part (2) there is a cavity (6) with the possibility of being located in besides, in the supporting part (1) there is a cutout (7) connected with its cavity (4), below which there is a through mounting hole (8), has distinctive features: the said cutout (7) is not connected with the cavity ( 6) the suspended part (2), wherein the thickness of the walls (3) of the suspended part (2) is not less than 2 mm and their width is not less than 10 mm, and the Shore D hardness of the said monolithic body of the holder is not less than 25 and not more than 90 units.

Such distinctive features make it possible to manufacture the holders in one piece, like brackets, without the need to separate them into their component parts and use additional fasteners, unlike the prototype [2].

The use of a single durable, volumetrically colored polymer material makes the holder resistant to loads and mechanical damage, and also greatly facilitates its installation or replacement. At the same time, possible color mismatches are eliminated, as can happen with other holders consisting of two or more separate elements, especially those made at different times and from different materials.

Additional distinctive features of the utility model:

- the cutout (7) is stepped;

- part of the cutout (7) is corrugated;

- the bottom of the cutout (7) is made at an angle (α) to the vertical axis (O1) of the cavity (6) of the hanging part (2) with an exit beyond the holder;

- the walls (3) of the suspended part (2) at its apex are conjugate with each other along a radius (R) from 2 to 15 mm;

- in the support part (1) opposite its cavity (4) there is a hole (9) connected to it with the possibility of installing a fixation element in it to the support device (5);

- on the outer side of the supporting part (1) there is a recess (10) connected to the hole (9), and there is also a protrusion (11) enclosing the recess (10);

- the depth (h) of the through mounting hole (8) is at least 3 millimeters, and the diameter (d) of its cylindrical part is from 5 to 16 millimeters.

The essence of the utility model is illustrated with illustrations, where:

- in fig. 1 shows a hand holder for passengers placed on the handrail of a vehicle according to the utility model;

- in fig. 2 shows the said holder in section AA according to FIG. 1;

- in fig. 3 is an enlarged detail view B of FIG. 1.

- in fig. 4 is an enlarged detail view C of FIG. 2.

The holder is a monolithic volumetric colored body made of a polymer based on polyamide, polybutylene terephthalate or other materials whose properties can ensure strength and durability (Fig. 1). It consists of a supporting part (1) and a suspended part (2) with walls (3) located along its vertical axis (01). Moreover, in the supporting part (1) a cavity (4) is formed with the possibility of the support device (5) passing through it, and in the suspended part (2) there is a cavity (b) with the possibility of placing the hands of passengers in it.

In addition, the support part (1) has a cutout (7) connected to its cavity (4), below which there are through fastening holes (8), which are designed to accommodate fasteners in the form of bolts and nuts.

The cavity (4) of the support part (1) is intended to accommodate support devices (5), such as handrails in the form of pipes. Volumetric painting of the holders is carried out to match the color of the supporting devices located, which increases the aesthetics of the vehicle interior.

The passenger hand holder is designed to be placed on the handrail of a vehicle (Fig. 1).

During the manufacturing process of the holder, the cutout (7) is made in steps, partially or completely. This is necessary to create engagement of its planes with each other (Fig. 3-4), ensuring increased reliability of fastening to the handrail of the vehicle, by increasing the resistance to tearing out the fastening bolt while holding passengers in place during sudden braking or rocking of the vehicle.

The dimensions of the cutout hooks (7) can be made either in the form of large teeth or in the form of small corrugations. When tightening the bolts and nuts through the mounting holes (8), the edges of the cutout (7) close, tightly enclosing the support devices (5) with the inner walls of the cavity (4) of the supporting part (1).

The bottom of the cutout (7) is made at an angle (α) to the vertical axis (O1) of the cavity (6) of the hanging part (2) with an exit beyond the holder (Fig. 4). This is necessary to facilitate the installation of the holder on the support device (5) by straightening the cavity (4) of the support part (1) along the cutout line (7) and putting the holder on the pipe of the support device (5). This installation method is convenient when the Shore D hardness of the monolithic body of the holder is not less than 25 and not more than 90 units, allowing the holder to be installed using the “snap” method without destroying the cavity (4) of the supporting part (1) around the pipe of the support device (5).

To ensure the safety of passengers' hands from possible pinching, the walls (3) of the suspended part (2) at its apex are mated to each other along a radius (R) from 2 to 15 mm (Fig. 2).

In the support part (1), opposite its cavity (4), a hole (9) can be made in communication with it, intended for installing fixation elements to the support device (5), for example, screws or rivets (Fig. 1-3). This solution is useful for ensuring a fixed and more secure attachment of the holder to the handrail in the vehicle interior. This is convenient for a more uniform distribution of holders along the handrails without passengers moving them independently, which has a beneficial effect on a more uniform distribution of standing passengers in the vehicle using said holder. At the same time, to strengthen the supporting part (1) of the holder, especially in the area with the hole (9), a protrusion (11) is made on the outer side of its supporting part (1) (Fig. 3).

In addition, the through hole (8) is stepped, which makes it possible to hide the heads of bolts and fastening nuts, eliminating injury to passengers, damage to clothing and hand luggage (Fig. 4). For the same purpose, the hole (9) for placing the elements for fixing the support devices there is made secret with a recess (10) of a conical (as shown in Fig. 3) or stepped (not shown) shape.

The depth (h) of the through mounting holes (8) is at least 3 millimeters, and the diameters (d) of these holes (8) are selected from the range of 6... 16 millimeters (Fig. 4). Such depths (h) and diameters (d) ensure sufficient strength of the holder and reliability of its installation on the support devices (5) in the vehicle interior.
