Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is applied to various bands such as ski goggles, rubber bands for wearing underwater glasses, and other bands for which body length needs to be adjusted. The present invention relates to a band adjusting ring used.

(Prior Art) A conventional band adjusting ring has band insertion holes formed at both ends, and a plurality of foot length fixing pins are integrally projected between the band insertion holes. A ring main body is provided with a receiving hole for the tip to correspond to the number of presser side fixing pins, and there is a width between the band insertion holes, and a plurality of presser side fixing pins of foot length are integrally projected on the surface. A synthetic resin consisting of a holding body having a receiving hole into which the tip of the fixing pin of the ring main body is inserted, and pin holes corresponding to the fixing pin and the holding-side fixing pin are provided. With one end of the band sandwiched between the ring body and the pressing body, the fixing pin and the pressing-side fixing pin are penetrated through the holes to protrude from the receiving hole, and the protruding fixing pin and pressing-side fixing pin Weld or crimp the tip of the ring with a welder and press the ring body By integrating the body, one end of the band is fixed.

(Problems to be solved by the invention) However, according to the above-mentioned conventional band adjusting ring, it is necessary to previously make a pin hole at one end of the band, which requires a labor for work, and this pin. The disadvantage of reducing the strength of the fixing part of the band by causing thread breakage due to the drilling of the hole, and further the time and effort to match the fixing pin of the ring body and the pressing side fixing pin of the pressing body with the pin hole of the band, There is a drawback that it is necessary to weld or crimp the tip of each pin protruding from the receiving hole with a welder.

An object of the present invention is to solve the above-mentioned drawbacks of the related art and to provide an inexpensive band adjusting ring capable of securely fixing the band end portion by a simple operation.

(Means for Solving the Problem) The band adjusting ring according to the present invention has the band insertion holes 1 at both ends.
A plurality of fixing pins 2 are integrally projected between the band insertion holes 1 and the receiving holes 3a into which the tips of the pressing side fixing pins 5 are inserted are made to correspond to the number of the pressing side fixing pins 5. The width B between the ring body 4 and the band insertion hole 1
And a presser body 6 having a plurality of presser side fixing pins 5 integrally projecting on its surface and having a receiving hole 3b into which the tip of the fixing pin 2 of the ring main body 4 is inserted. In the band adjusting ring, the tips of the fixing pin 2 and the presser-side fixing pin 5 are made to be cusps 7, and the ring body 4 and the presser body 6 are openably and closably coupled by an integral hinge 8 to freely open and close each other. This is a structure in which the ends are locked by a locking means utilizing the elasticity of synthetic resin.

(Embodiment) An embodiment of the band adjusting ring of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing a state where the ring body 4 and the pressing body 6 are opened, FIG. 2 is a cross-sectional view in the width direction when a rubber band is sandwiched, and FIG.
The figure is a cross-sectional view in the same band length direction, and is wholly formed integrally of synthetic resin.

A band insertion hole 1 is opened at both ends of the ring body 4 portion, and the tip is pointed at the tip 7 in the center width direction between the band insertion holes 1.
The two fixing pins 2 are integrally projectingly provided, and on both sides of the fixing pin 5, there are receiving holes 3a into which the tips of the four holding-side fixing pins 5 described later are inserted. The opening is made in correspondence with the number, and a locking hole 9 is opened at the open / close end.

Further, the pressing body 6 portion is connected to the ring body 4 by a hinge 8 so as to be openable and closable, and has a width B which is less than the space between the band insertion holes 1.
Four presser side fixing pins 5 having a pointed tip 7 are integrally projectingly provided on the surface thereof, and between the presser side fixing pins 5, the fixing pins 2 of the ring body 4 are provided. Receiving hole 3b where the tip enters
Is provided, and a mushroom-shaped projection 10 that is locked and fixed in the locking hole 9 of the ring body 4 is provided at the open / close end.

The band adjusting ring constructed as described above is shown in FIGS.
As shown in the figure, one end of the rubber band A is sandwiched between the ring body 4 which is opened and closed by the hinge 8 and the holding body 6, and the mushroom-shaped projection 10 at the free end of the ring body 4 and the holding body 6 is held. And one end of the rubber band A are sandwiched by engaging with the locking hole 9 and the other end of the rubber band A is meandered through the band insertion hole 1 to move the other end. It is used to adjust the length.

In the above embodiment, the fixing pin 2 and the presser side fixing pin 5 are used.
Although the tip has been described as a pointed tip 7, the same action and effect can be obtained even if the tip has a hemispherical shape as long as the shaft diameter is small. Further, in the above embodiment, the elasticity of the synthetic resin is As the locking means used, the structure in which the locking hole 9 and the mushroom-shaped projection 10 to be locked and fixed to the hole 9 are provided has been described.
It is not limited to this, but as shown in FIG.
The free end 11 of the pressing body 6 may be locked by the claw edge 12 formed on the ring body 4.

(Advantageous effects of the invention) The band adjusting ring configured as described above has one end of the band sandwiched between the ring body and the pressing body that are opened and closed by the hinge, and the free ends of the ring body and the pressing body are made of resin. By using the elasticity of the ring to engage with each other, one end of the band can be securely fixed by penetrating and fixing by the fixing pin of the ring body and the pressing body and each receiving hole, and by sandwiching between the ring body and the pressing body. At the same time, the ring body and the pressing body can be integrally molded and can be provided at low cost, and there is no loss of parts, and the fixing pin of the ring body and the pressing side fixing pin of the pressing body can be pinned to the band as in the past. The work of matching the holes and the work of welding or crimping the tips of the pins protruding from the receiving holes by the welder are unnecessary, and the band can be securely clamped with one touch.

Further, since the tips of the fixing pin and the pressing-side fixing pin that are integrally projected on the inner surface of the ring body and the pressing body are pointed or hemispherical, each fixing pin pushes open the weave or stitch of the band. It does not enter and cut the thread. Therefore, it is possible to eliminate the trouble of drilling a hole at one end of the band, and also to eliminate the decrease in the strength of the sandwiching and fixing portion caused by drilling the hole, thereby providing a band adjusting ring having excellent durability. .
