Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is an improvement of the "belt length adjuster" used for suspenders and the like, and more specifically, the belt is automatically tracked according to the movement of the suspender wearer. It relates to a belt length adjuster that can be pulled out and rolled up, and will be widely used for suspenders such as formal wear and ski wear.

[Problems to be solved by conventional technology and device]

Belt length adjusters used for suspenders such as ski wear have conventionally consisted of removable plugs and sockets, and one belt was fixed to the belt connecting rod of the plug and integrated into the socket. The buckle type in which the other belt is wound around the molded "day-shaped" belt adjuster so that the length of the belt can be adjusted is often used in practice.

By the way, in the above-mentioned buckle type belt length adjuster, not only the pulling force acting on the belt in the normal sitting / standing operation but also the bending / extending motion during downhill or the impact on the belt when it falls The strong tension applied may loosen the belt wound around the belt adjuster, and in such a case, the belt length must be adjusted each time.

In the above belt length adjuster, when adjusting the length of the belt, since the belts are in contact with each other at the belt locking rod portion in the center of the belt adjuster, the friction force of the belt adjuster Even if the belt tip is pulled, it cannot be pulled out easily.Therefore, the complicated operation of pushing the belt body side toward the belt adjuster side to loosen the belt and then pulling out the belt tip was forced. Is.

The present invention has been made in view of the above-mentioned circumstances of the belt length adjuster, which eliminates the need to adjust the belt length at all, and makes the belt always fit physically. It is a technical object to provide a practical belt length adjuster that can be brought into close contact with the belt and that can prevent the belt from loosening.

The reference numeral (4) indicates a rope winding device that functions as a winding means for the rope (3), which is fixed to the back of the breast pad of the ski wear's salopette pants (P) with a tack or the like. (See FIG. 1). As shown in FIGS. 3 and 4, the rope winding device (4) has a rotating ring (43) arranged between a substantially square upper cover (41) and a lower cover (42). However, the spiral spring (44) is arranged inside the rotating ring (43).

The rotating ring (43) has an annular connecting portion (431) protruding from the back surface of the upper circular plate (43a) and a lower circular plate (43b).
It is made into a bobbin shape by being fitted in the annular groove (432) of. In this rotating ring (43), the stepped annular shaft portion (41a) of the upper cover (41) is rotatably fitted into a round upper bearing hole (433) formed in the center of the upper circular plate (43a). In addition, the circular convex portion (4) of the lower cover (42) is inserted into the round lower bearing hole (434) formed in the center of the lower circular plate (43b).
By rotatably fitting 2a), it is rotatably sandwiched by the upper and lower covers (41, 42). And, in the annular connecting portion (431) of the rotating ring (43),
The other end (3b) of the rope (3) is connected to the annular connecting portion (43).

On the other hand, the spiral spring (44) is arranged around the stepped annular shaft portion (41a) of the upper cover (41) inside the annular connecting portion (431) of the rotating ring (43). The spiral spring (44) is fixed to the annular connecting portion (43b) of the one end ring (43) so that the rotating ring (43) rotates the other end (3b) of the rope clockwise.
The other end is fixed to the stepped annular shaft portion (41a).

Thus, the rope winding device (4) has a spiral spring (4
The rotating ring (43) is rotated in the clockwise direction by the urging force of 4), and the annular connecting portion (431) of the rotating ring (43) is rotated.
It functions to wind the other end (3b) of the rope (3) around the outer circumference of. Incidentally, the reason why the spiral spring (44) is adopted as a means for rotating the rotating ring (43) is to wind the rope (3) with a constant winding force when a tensile force acts on the belt (V). Thus, the tension of the belt (V) becomes constant, and the belt (V) fits the body of the suspender wearer perfectly.

What is designated by reference numeral (5) is a belt tension holding mechanism provided in the rope winding device (4).
As shown in FIG. 4, the belt tension holding mechanism (5) includes a brake member (51) that is vertically movable on an upper cover (41) and abuts on a rotating ring (43), and a lower cover (42). The rotary knob (52) rotatably attached to the brake member (51) and fixed to the brake member (51), and the brake member (51) elastically mounted between the upper cover (41) and the rotary knob (52) to rotate the ring ( It consists of a compression coil spring (53) biased to the 43) side.

The brake member (51) is composed of a plate (51a) and a screw shaft (51b) projecting from the center of the back surface of the plate (51a), and has a substantially T-shaped cross section. The brake member (51) includes a plurality of protrusions (51c) formed concentrically with the screw shaft (51b) on the back surface of the plate (51a).
Is fitted into a through hole (41b) formed in the upper cover (41) and is in contact with the surface of the upper circular plate (43a) of the rotating ring (43). And the brake member (51)
The screw shaft (51b) is the stepped annular shaft part (4
It is vertically movably fitted in a shaft hole (41c) formed so as to penetrate through 1a). The rotary knob (52) has a shaft hole (42b) formed in the center of the annular projection (42a) of the lower plate (42) and a recess (41b) formed at the tip of the stepped annular shaft (41a). It is rotatably fitted. In this rotary knob (52), the brake member (5
The screw shaft (51b) of 1) is screwed in. The compression coil spring (53) is loosely inserted in the screw shaft (51b) of the brake member (51) and mounted in the recess (41d) of the stepped annular shaft portion (41a).

Then, in the belt tension holding mechanism (5), the rotation knob (52) is further attached to the screw shaft (51) of the brake member (51).
By being screwed into the b), the protrusion (51c) of the brake member (51) strongly abuts the rotating ring (43) by the elastic force of the compression coil spring (53), and the rotating ring (43) is moved to a predetermined position. Can be stopped in position.

Next, the operation of the belt length adjuster according to this embodiment will be described.

First, when a pulling force acts on the belt (V), the rope (3) is pulled toward the belt (V) side, and this pulling force is passed through the other end (3b) of the rope (3) to the rope winding device (4). It acts on the rotating ring (43). As a result, the rotating ring (43) rotates counterclockwise against the biasing force of the spiral spring (44), so that the other end (3b) of the rope (3) connects the rotating ring (43) in an annular manner. It is pulled out from the department (431).

Then, when the tensile force does not act on the belt (V), the rotating ring (43) of the rope winding device (4) rotates clockwise by the urging force of the spiral spring (44) and the rope (3). The other end (3b) of the rope (3) is pulled, whereby the other end (3b) of the rope (3) is wound around the outer periphery of the annular coupling portion (431) of the rotating ring (43), and the belt (V) is used for suspenders It closely adheres to the person's body.

In this state, rotate the knob (52) of the belt tension holding mechanism (5) to the screw shaft (51b) of the brake member (51).
It is screwed into and the rotation function of the rotating ring (43) is locked by the protrusion (51c) of the brake member (51),
The other end (3b) of the rope (3) cannot be pulled out from the rotating ring (43), and the slack of the belt (V) is prevented.

The product of this embodiment is constructed as described above, but the present invention is not limited to the embodiment described above.
Various changes can be made in the description within the “claim for utility model registration”. For example, in the above embodiment, an example in which the pair of pulleys (1) around which the rope (3) is wound is attached to the holding member (2) directly connected to the belt (V) has been described, but as shown in FIG. A conventionally known buckle (6) including a detachable plug (61) and a socket (62) is used for the belt connecting portion (61) of the plug (61).
The belt (V) is connected to (a), and the holder (62a) having a U-shaped cross section is integrally provided on the socket (62).
It is of course within the technical scope of the present invention that the pulley (1) is rotatably supported on both left and right sides of 2a).

[Effect of device]

As described in detail above, according to the present invention, when a tension force is applied to the belt, the rotating ring of the rope winding device resists the urging force of the spring means and is in a direction opposite to the urging direction. When the other end of the rope is pulled out from the rope winding device and the tension force does not act on the belt, the rotating ring of the rope winding device moves in the urging direction by the urging force of the spring means. As it rotates, the rotating ring pulls the other end of the rope to wind it up, and the rope winder automatically adjusts the length of the bell following the movement of the suspender wearer. It is not necessary to adjust the length of the belt, and it is possible to prevent such a problem that the belt comes into close contact with the body and comes off the shoulder.

Further, by further screwing the rotary knob of the belt tension holding mechanism into the screw shaft of the brake member to lock the rotary function of the rotary ring, it becomes impossible to pull out the other end of the rope from the rope winding device. Therefore, the slack of the belt can be prevented.
