Description

SUBSTANCE: invention relates to means for fixing belts, tapes, harnesses and other tightening elements and can be used for fastening the end of a belt web in a retainer. In addition, the tip of the proposed design can decorate the end of the belt decoratively, ensuring its safety and preventing the destruction of the end part of the belt fabric. As such a belt web, various harnesses can be used, including medical, tie-down tapes or seat belts, belts, harnesses, straps, cords, etc.

State of the art

To perform a decorative function, they most often use simple tips or trailers (https://www.xobbyland.rf/index.php?route=product/category&path=59_99_2387_27_1(6)), which are either a metal bracket or trailers with a spring block .

However, these devices are not applicable for fixing the ends of seat belts and medical harnesses due to insufficient fixation.

In the solution GB 2138490 A, the end of the bundle is simply placed in the corresponding groove of the latch, which makes this solution inapplicable for use with high loads on the bundle.

More often, the end of the belt is passed through the groove of the latch and stitched to the main fabric (EP (11) 77735 B1). However, such fasteners are also not reliable.

The design of the shutter for the end of the tape, disclosed in patent source US 5121954, seems to be rather complicated. . The connecting elements include a pin protruding from the valve body, having a front end with two oppositely inclined surfaces and two transverse grooves, and two sliders placed in the body cover with the possibility of sliding one above the other, each of them has a protrusion that faces each other and is made so that in the locked state they engage with the grooves of the bolt body pin.

The shutter is characterized by the complexity of the design, the abundance of interconnected parts, the strength of the entire structure depends on the mutual strength of which.

Also known from US Pat. No. 5,535,485 is a solution for fixing the end of the tape in a retainer. The tape is inserted with the bent end back into the undercut groove, the width of which is equivalent to about twice the thickness of the tape. When the belt is tensioned, its half-folded part tends to turn around, as a result, it rests even more against the walls of the groove and, thereby, is firmly clamped. This effect is enhanced if there is a rigid band clamp at the end of the tape.

The closest in technical essence to the claimed invention is the tip solution disclosed in RF patent No. 2255(6)82 "Device for applying a hemostatic tourniquet on body parts".

The latch block (in the terminology of the application - a tip) includes a body and a fixing insert, consisting of two parts in the form of plates, one of which is made with holes, the other with spikes. A tape is installed between them, and the insert is fixed in the body of the retainer block. And the latch block with the tape placed in it is installed in the lock of the device for applying a tourniquet with the formation of a loop.

The fixing insert due to the prefabricated structure does not provide a reliable connection with the housing. In addition, when clamping the end of the bundle, it is necessary to ensure accuracy when combining the spikes and holes, otherwise the fastening will be unreliable.

The technical problem solved by the claimed invention is the need to overcome the shortcomings inherent in analogues and the prototype, by creating a tip that has both a simple design and provides secure fixation of the end of the tape, belt or harness.

Brief summary of the invention

The technical result achieved by using the claimed invention is to expand the arsenal of known means of fastening the end of the tape or bundle, by creating an easy-to-manufacture and assemble design of the tape retainer tip.

The claimed technical result is achieved by the solution of the latch tip (10), which includes in all versions the body (1) with the cavity (2) of Fig. 1-4a, 4b, fig. 6-9a, 9b and insert (6) of fig. 5A, 5B.

The insert in all versions is intended for placement in the cavity (2) and is made in the form of a plate (6) with at least one spike (7) protruding on the same plane of Fig. 5A, and on the reverse plane on the edge it is equipped with a locking protrusion (8) of fig.5b, designed to engage the wall of the housing (1), and on the other edge from the side of the plane with spikes, it is equipped with a thrust bar (12) covering the open end of the housing ( 1) fig. 5A, 5B after installation.

Housing (1) in all versions of Fig. 1-4a, 4b, fig. 6 - 9a, 9b is made in the form of a one-piece one-piece element with an upper (1.1) and lower (1.2) bases and an end (1.3) open on one side, designed to accommodate an insert (6), and provided with a hole (3) for inserting a tape ( 11) into the cavity of the body (1) for fixation, the upper base of the body (1.1) from the side of the cavity (2) is equipped with a shelf (4) with grooves (5) designed to slide the spikes (7) when inserting the insert (6) into the cavity ( 2) body (1).

According to any embodiment of the claimed solution, the number and shape of the groove (5) coincides with the number and shape of the spike (7).

In an embodiment, the opening (3) of FIG. 1, 3, 4a for inserting the tape (11) into the cavity (2) of the body (1) is made in the lower base (1.2) of the body (1). The insert (6) in this embodiment, when placed in the cavity (2) by the locking protrusion (8) of Fig. 5b, engages with the bottom wall of the housing (1) of Fig. one.

In another embodiment, the hole for inserting the tape (11) into the cavity (2) of the body (1) is made in the end face (1.4) of the body (1) of Fig. 6, 8 opposite the open end (1.3) of FIG. 6, 8, 9a, 9b. The insert (6) in this embodiment, when placed in the cavity (2) by the locking protrusion (8) of Fig. 5b, engages with the bottom wall of the housing (1) of Fig. 6.

According to any embodiment of the claimed solution, the number of spikes (7) on the insert is 1 or more.

According to any embodiment of the claimed solution, the spike(s) (7) can be made in a conical or pyramidal shape. In a particular case of execution, the spikes may have a slope angle of 20-45°.

According to any embodiment of the claimed solution, the shelf can have a variable thickness, providing a decrease in the height of the cavity from the open end to the opposite one.

In a particular case of execution, the height of the fixing protrusion of the insert is not more than 3 mm. According to any embodiment of the claimed solution, the locking protrusion (8) can be located in the central part of the insert of FIG. 5b or across the entire width of the insert.

According to any embodiment of the claimed solution, the tip can be made in the form of a separate part connected by any known method to the latch (10) or made with it as a single part.

In a particular embodiment, the latch (10) can be made, for example, in the form of a latch in FIG. 4b or paper clips of Fig. 9a.

Inseparability, the execution of the housing (1) Fig.1-4A, 4B, Fig.6-9A, 9B in the form of a single piece greatly simplifies the assembly of the tip, reduces the risk of destruction of the connecting elements due to their absence. Unlike the prototype, the spikes (7) in the proposed solution pass through the grooves (5) with their upper part, and are not centered in special holes, which also helps to simplify the assembly of the tip. The presence of the shelf (4), in which the grooves (5) are made, ensures the preservation of the strength properties of the housing (1) by preventing the integrity of the upper wall of the housing. Insert (6) with locking lug (8) ensures secure fixation of insert (6) in cavity (2) of body (1), and the presence of a thrust wall isolates the tape from external influences.

The technical advantages of the device also include a high degree of strength and rigidity of the product, due to the minimum number of mating parts, a high degree of reliability and safety of operation of the device, provided by the presence of fixing nodes in the form of spikes and protrusions.

Implementation of the invention

The inventive tip provides secure fixation of the tape, belt or harness. The tip may be connected or mated with a latch or other fastener, which, in turn, can be releasably connected to any type of lock. The tip includes a body (1) of FIG. 1-4a, 4b, fig. 6-9a, 9b and the insert (6) of FIG. 5A, 5B, between which the tape (11) of FIG. 1-3, 6-8.

The body (1) of the tip is a solid, for example, stamped, part, made, for example, of plastic.

Unlike the prototype, the housing (1) is made non-separable, which increases its strength during use and reduces the risk of breakage when the belt (11) is tensioned. The shape of the outer surface of the housing (1) does not affect its fixing properties and any one can be chosen.

In the body (1) there is a cavity (2) designed to accommodate an insert (6) with a tape (11). The shape and dimensions of the cavity (2) are determined by the dimensions of the tape placed in the cavity (2). Thus, the width of the cavity (2) makes it possible to pass the tape in it without hindrance, that is, it corresponds to the width of the tape with a small gap from the walls of the housing (1). The height of the cavity (2) is also chosen taking into account the thickness of the tape (11) and the thickness of the insert (6). An elongated hole (3) is made in the body (1) for inserting a tape web into the cavity (2) through it. Such a hole (3) is associated with the cavity (2) and can be made, for example, in the lower base of the housing (according to option 1) of Fig. 1 or at the end of the housing (1) opposite the open end (option 2) of FIG. (6). The shape of the hole is determined by the form factor of the tape and, mainly, the hole (3) has a rectangular shape, the width and length of which correspond to the thickness and width of the tape (11) inserted into the body (1). A small gap between the indicated dimensions is allowed, a large gap contributes to the abrasion of the tape (11) during use. The upper wall of the body (1) is equipped with a shelf (4) from the inside, which is a thickening (9) of the upper wall with longitudinal grooves (5), the depth of which does not exceed the thickness of the shelf (4). The thickening (9) may have a variable thickness, for example, with an increase in size away from the open end of the body (1). Such an implementation will provide additional clamping of the tape (11) when placing the insert (6) in the cavity (2). The execution of grooves (5) without thickening the upper wall will violate its strength and integrity, as a result of which the tip may be broken during operation. Shelf (4) enhances the strength properties of the tip. The shape of the grooves (5) corresponds to the shape of the spikes (7) made on the insert (6). The length of the grooves is chosen taking into account the need to fix the tape in a certain position. The depth of the grooves, as a rule, is no more than (3) mm. The insert ((6)) is made in the form of an L-shaped plate, the width of which corresponds to the width of the cavity (2) of the housing (1). Spikes (7) are formed on the surface of the plate (6), on which the tape is attached. The upper parts of the spikes (7) when the insert (6) is placed in the cavity (2) are installed in the grooves (5). The number and principle of placement of the grooves (5) do not affect the achievement of the technical result, however, for reasons of reasonableness and reliability of fastening the tape (11), it is proposed to place the spikes (7), for example, evenly in a row (for example, in the amount of 3-4 pcs. ), and make them in the form of cones. However, the shape of the spikes (7) can be any, preferably pointed at the top, for example, pyramidal. The pointed shape will allow easy piercing of the tape web when it is fixed. The height of the spikes (7) is chosen taking into account the need to get them into the upper parts of the grooves (5). A locking protrusion (8) is made in the end part of the plate on the lower side. The protrusion (8) is designed to fix the insert (6) when it is placed in the cavity (2). The insert (6) in this end part may have a rounding designed to accommodate the tape. The locking protrusion can be formed only in the central part of the end face of the insert or along the entire end face. From the opposite end, the insert plate is equipped with a thrust bar (12), which, in combination with the plate, forms an L-shaped insert profile. The thrust bar (12) when the insert is placed in the cavity (2) closes the open end of the housing (1) and prevents foreign objects from entering the cavity (2).

The tip is used as follows. The tape (11) is passed through the hole (3) in the lower wall (or end) of the housing (1) through the cavity (2) of the housing (1) and is taken out. The tape (11) is placed on the insert plate (6) and abutted against the thrust bar (12) of the insert (6), while the spikes (7) pierce the web of the tape (11) and come out. Then the insert (6) is inserted into the cavity (2) of the housing (1), while pulling the tape (11) through the hole (3). The tape (11) is held on the insert (6) by spikes (7) and does not slip off it. The upper parts of the spikes (7) move along the grooves (5) until they stop. In this case, the protrusion (8) of the insert (6) enters the hole (3) and securely engages with the wall of the housing (1), without the possibility of movement in the opposite direction. At the same time, the stop bar (12) with its upper part rests against the shelf (4) and without the possibility of further displacement of the insert (6) forward. Thus, the insert with the tape is rigidly fixed on both sides. The tape (11), in turn, is sandwiched between the shelf (4) and the insert (6), fixed with spikes (7) resting against the grooves (5) of the shelf (4). The tape web (11) is brought out through the hole (3). All elements of the device are firmly connected to each other, without the possibility of any displacement, which ensures reliable fixation of the tape (11).

An example of a specific implementation.

The claimed solution is embodied in the design of the device for applying the tourniquet, the tape of which is fixed in the tip of the latch and is securely held by it, and the latch (10) was installed in the body of the lock of the device for applying the tourniquet.

The tip has a one-piece plastic case with an open end for placing an insert (6) in the cavity (2) of the body (1) and a hole (3) measuring 3 × 25 mm for inserting a tape 25 mm wide and 2 mm thick with an allowable gap between the boundaries of the hole and tape no more than 1-2 mm. In the cavity 2 of the housing 1 on the upper wall there is a shelf (4) with a thickness of 0.8 mm, in which three grooves (3) are made with a depth of 0.8 mm and a length of 6.5 mm. The insert (6) is L-shaped and equipped with three conical spikes (7) 2.6 mm high with a base diameter of 1.5 mm. At the end of the plate (6) there is a protrusion (8), not more than 0.6 mm high, which ensures the fixation of the insert (6) in the cavity (2) of the body (1).
