[Industrial applications]

 The present invention relates to a structure of a tightening band, and more particularly to a structure in which the tightening condition of the band can be adjusted more quickly and comfortably and by an operation in conformity with ergonomics.

[0002]

[Prior art]

 Conventional tightening bands are generally made of elastic material (silicon rubber or rubber, etc.) that is integrally molded into a single band, and both ends of the band are folded back and connected at both sides of the connection part of the property. To adjust the tightness, the bands folded at the connecting parts on both sides are pulled backward and squeezed to the rear, and the elastic force generated by pulling is applied to the user by pressing an appropriate part.

The above-mentioned conventional single-tightening type tightening band has the following drawbacks in actual use: (1) Although the tightening operation is performed by pulling the folded-back portions on both sides rearward. As such, the motion of bending the hands on both sides of the head and pulling them backward could not be performed smoothly, resulting in the sensation of pressing the elbow. In addition, such an operation of applying a rearward force at the same time also pulls back the portion to which the band is attached, for example, the head of the user, so that the user needs to tilt the head forward. Yes, this balanced the force of pulling the folded back part of the band backwards, preventing the head from being towed and allowing the folded back part of the band to be pulled backwards. However, this type of method requires a combination of actions in which the user's head is directed in the opposite direction, so this action was not in accordance with ergonomics. (2) Since the band is of a single-joint type, the entire band is relatively long from the front end to the rear end, and in addition the pulling force is applied to prevent friction on the user's head when wearing the band. When applied to the folded parts on both sides of the band, the tightening force is not ideally transferred to each part of the band quickly and evenly, and both ends are specially tightened, which results in non-uniformity of the band and The phenomenon of not being comfortable to wear occurred. (3) When arranging necessary equipment on both sides of the band, such as a snorkel attached to the goggles band at the time of diving, usually a hook ring is provided on one side of the band at the same time and a snorkel is hung on it. Folded portions of the band that are on both sides of the conventional band and that are folded back interfere with the placement and operation of these hook rings and respiratory tract. At the same time, the operation of relatively tightening and loosening the band is disturbed.

FIG. 1 is an external perspective view of an embodiment in which the present invention is used for goggles, FIG. 2 is an exploded perspective view of the present invention, FIG. 3 is a partial sectional view of the present invention, and FIG. 4 is a band of the present invention for diving foot fins. It is a perspective view which shows the state used. As shown in the above figures, the present invention includes one arc-shaped mounting plate (1), two bands (2) and two pressure plates (3).

The above-mentioned arc-shaped mounting plate (1) has one arc-shaped plate body (11), which is the wear part of the user, in the embodiment of FIG. 1, the arc of the occipital region of the user. It is provided to fit the outer surface of the shape and make it comfortable to wear. Penetration grooves (12) are provided on both sides of the outer surface of the arc-shaped plate (11) with symmetry. Openings (13) are formed on the striking sides of these through-grooves (12), and shaft columns (14) are provided respectively. Further, a structure used for attaching the pressure plate (3), for example, a hook hole is provided in the central portion of the outer surface of the arc-shaped attachment plate (1).

The band (2) described above is made of an elastic material such as rubber or silicon rubber and has elasticity, and each of these bands has a plurality of check projections (21) protruding from its outer surface. Have. An inclined surface (22) and an acute angle surface (23) are formed on each non-return projection (21), and an edge (24) is formed between them. When these bands are under control, they are pulled from the slope direction. However, these bands are prevented from shrinking and returning from the direction of the acute angle. The fixed ends (25) of these bands are respectively pivoted to both sides of the frame of the object to be used, eg goggles (4) as shown in FIG. 1 and diving foot fins (5) as shown in FIG. Now, the free ends, that is, the folded back parts, pass through the through holes (12) on both sides of the arc-shaped mounting plate (1) and hang around the shaft column (14), and further toward both outer sides. Will be folded back. As a result, a folded portion is formed at the free end portion. After this folded-back portion is folded back, the non-return projection on it also turns and faces inwardly, and in combination with the non-returned non-return projection on the band (21), it is locked at the shaft post (14). To

In the above-described connecting structure of the pressure plate (3) and the arcuate mounting plate (1), for example, the pressure plate (3) is provided with the hooks (31) respectively, and the hook holes of the arcuate mounting plate (1) are respectively provided. The pressure plate (3) is provided with an elastic structure, such as a spring, which is engaged with the pressure plate (3) and can be opened on the outside by being joined to the pressure plate (3), or as shown in FIG. A groove (32) is provided on the surface of the pressure plate (3) so that the inner side of the pressure plate (3) is connected to the outer end (33) (operating part) of the pressure plate (3) and the outer side of the pressure plate (3) can be opened. The non-return projections (34) having the same structure as the above-mentioned band (2) are provided on the inner surfaces of these operation portions. As shown in FIG. 3, in a normal state, the outer end portions (33) (operating portions) of the respective pressure plates (3) are pressed inwardly, and their respective non-returning protrusions (34) respectively engage the bands (2). ) Of the folded back portion (26) is suppressed, so that the band can maintain the current tightening condition at any time.

When the present invention is applied to an object to be used, for example, goggles or a fin for diving, and is used for a wear part of a user, it is convenient to wear in the first loosened state. However, the user can simultaneously pull the folded-back portions (26) on both sides of the band outward until they have a proper tightening force, and the pulling operation toward the outside (see arrow a in Fig. 3). Is carried out in a forward direction with respect to the non-return projection (34) of the pressure plate (3) or the non-return projection (21) of the band (2), so that the folded-back portion (26) is pulled outward. The tightness can be retained. At this time, the non-return projection (34) of the pressure plate (3) presses inward, and at the same time, prevents the band (2) from contracting inward. The action of contracting in this direction is opposite to the non-return projection (34) of the pressure plate (3) or the non-return projection (21) of the band (2), thus preventing the band from contracting (Fig. 3). (Refer to arrow b) of FIG. 3) to prevent the situation of unintentional loosening. After use, when removing the band of the present invention and the article provided with the band, only raise the outer end portion (33) of the pressure plate (3) outwardly, and suppress the folded portion (26) of the check projection (34). When the band (2) is released, the band (2) is released from the pulling force and is restored to its original slack state due to the restoring force (see the imaginary line arrow c in Fig. 3) and is ready for removal by the user. To be done.
