Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a band stopper that can hold a band, string, etc. at any position.

(Prior art) As a conventional stop, for example,
There is a buckle as described in Publication No. 19309.
In this method, the side plates are fixed at regular intervals by the shaft, and the base end of the hanging plate is rotatably attached between the shafts, the tip is supported on the shaft, and the base end of the rotating plate is rotatably attached to the shaft. It is attached so that the tip faces the rough surface of the tip of the latching plate.

Recently, due to the demands for ease of processing, fashionability, weight reduction, etc., there are many products made of plastic, such as a band stopper as shown in FIG. A base body 30 is formed by vertically disposing left and right rising pieces 32 on both sides of a base plate 31. A pivot hole 33 is formed in each of the left and right rising pieces 32, and an operating body 34 is inserted into the pivot hole 33. Left and right locking protrusions 35 protruding from both ends of the base body 3 are pivotally supported.
0, and the operation body 34
The operating body 34 is configured to be in a non-clamping state when it is in an upright state with respect to the base body 30, and to be in a clamping state when the operating body 34 is in a lying state with respect to the base body 30.

(Problem to be Solved by the Invention) However, in the case of the buckle described above, the frame body is constructed by connecting the left and right side plates with a plurality of shafts, and the rotating plate and the locking plate are each connected to the frame. At the same time as the body is assembled, it must be swingably attached to the frame body via a shaft, which has the disadvantage that the work of assembling the frame body and attaching the rotary plate and the hanging plate becomes extremely troublesome. Moreover, the number of component parts increases, making manufacturing cumbersome and making it difficult to provide at a low price.

In addition, the above-mentioned band stopper has a base body 30 that is connected to a base plate 31 and rising pieces 32 provided on both sides of the base body 30.
Since the front surface is formed in a substantially upward groove shape,
When a strong external force is applied to the upright piece 32 from the left and right directions, the tip of the upright piece 32 tends to move from side to side, causing the problem that the upright piece 32 is easily separated from its root. Furthermore, a shaft support hole 33 bored in the rising piece 32
Since the operating body 34 is configured to be able to swing freely between the locking protrusion 35 of the operating body 34 which is pivotally supported in the pivot hole 33, the pivot hole 30 of the upright piece 32
The surrounding portion and the root of the locking protrusion 35 tend to lack strength and are easily damaged. Moreover, when the operating body 34 is in the laid down state, the upper end portion of the rising piece 32 above the pivot hole 35 protrudes upward from the upper surface of the operating body 34, so if this part touches the body, the sensation will be Worse, for example, when the protruding portion comes into contact with clothing such as a kimono, it leaves a dent in the clothing. In particular, conventional products have the disadvantage that they do not have sufficient overall strength and are often susceptible to decomposition or damage.

(Means for Solving the Problems) Therefore, the present invention is intended to solve the above-mentioned difficulties and to provide a band stopper that can provide reliable clamping force at a low cost. Specifically, left and right rising pieces 2 are provided vertically at both ends of the board 1, and a shaft rod 3 is horizontally connected to the upper end of each of the left and right rising pieces 2, so that the board 1 is integrally formed into a substantially rectangular frame shape from the front. A base A made of synthetic resin, and a rod accommodating groove 10 having a substantially U-shaped cross section capable of accommodating the rod 3 are recessed in the upper surface near the tip, and the rod 3 can be accommodated in the rod accommodating groove 10. It consists of a synthetic resin operating body B attached to a base body A so as to be able to swing freely up and down at the center. When the operating body B is in a state of lying down with respect to the base body A, the base plate 1 of the base body A and the locking piece 11 at the tip of the operating body B are formed so that an object to be held, such as a band 20, can be clamped. Furthermore, when the operating body B is in an upright state with respect to the base body A, the clamping state between the base plate 1 and the locking piece 11 is released. Further, a protrusion guide groove 4 recessed on the inner side surface of each of the rising pieces 2, and a protrusion guide groove 4 provided protrudingly provided on the upper part of both side ends of the locking piece 11,
With a locking protrusion 12 that is movable within the protrusion guide groove 4,
A means is adopted to restrict the range of swing of the operating body B relative to the base body A, and to prevent the engagement between the shaft accommodating groove 10 and the shaft 3 from being released.

(Example) Hereinafter, the present invention will be explained with reference to illustrated examples.

The band fastener of the present invention has left and right rising pieces 2 each having a substantially semicircular plate shape vertically disposed on both side edges of a horizontally long rectangular plate-like substrate 1 whose long pieces are slightly curved outward.
A synthetic resin base A is integrally formed into a substantially rectangular frame shape from the front by horizontally connecting a round shaft-shaped shaft rod 3 to the upper end apex of each of the left and right rising pieces 2, and the shaft rod 3 is recessed. A rod-accommodating recess 10 having a substantially U-shaped cross section that can be accommodated is recessed in the upper surface near the tip of the rod-receiving groove 1.
The operation body B is made of a synthetic resin and has a substantially rectangular planar shape, which is attached to the base body A so as to be swingable about a shaft rod 3 that falls within the range of 0. Moreover, when the operating body B is in a laid down state with respect to the base A, the stopper of this band is
An object to be held, such as a band 20, can be held between the substrate 1 and the locking piece 11 at the tip of the operating body B, and the operating body B is attached to the base A.
When the board 1 and the locking piece 1 are in an upright state,
The structure is such that the clamped state between the two parts is released. Further, protrusion guide grooves 4 are provided on the inner side surfaces of the left and right rising pieces 2, respectively, and the locking pieces 1 of the operating body B
1, locking protrusions 12 are protruded from the upper part of each side end,
The protrusion guide groove 4 and the locking protrusion 12 that is movable within the protrusion guide groove 4 restrict the swinging range of the operating body B relative to the base body A, and the engagement between the shaft rod accommodation groove 10 and the shaft rod 3 is controlled. The status is configured so that it will not be released.

In the figure, reference numeral 5 denotes a protrusion passage recess through which the locking protrusion 12 of the operating body B can be easily accommodated in the protrusion guide groove 4 when the operating body B is attached to the base body A. 5 is formed on the inner side surface of at least one of the rising pieces 2. That is, the distance between the ends of the left and right locking protrusions 12 of the operating body B is approximately the same as or slightly narrower than the distance between the rear walls of the left and right protrusion guide grooves 4, and is greater than or equal to the distance between the inner side surfaces of the left and right rising pieces 2. Therefore, when the locking protrusion 12 of the operating body B is housed in the protrusion guide groove 4, the left and right locking protrusions 12
By making the line connecting them oblique to the base A, one of the locking protrusions 12 can be directly accommodated in the protrusion guide groove 4, so the other locking protrusion 12 can be forcibly pushed in. Ease of installation is achieved by housing the protrusion in the guide groove 4. Incidentally, the protrusion passage recess 5 may be formed on the inner surfaces of the left and right rising pieces 2 that face each other in parallel. Incidentally, a protrusion stop step 6 is provided between the protrusion passage recess 5 and the protrusion guide groove 4 to prevent the locking protrusion 12 accommodated in the protrusion guide groove 4 from escaping to the side of the protrusion passage recess 5. It is being Further, the protrusion stop step portion 6 may be constructed by simply protruding appropriate protrusions from the inner surfaces of the left and right rising pieces 2, respectively.

In addition, 13 in the figure indicates a mounting part provided with a band mounting hole 14 through which an object to be held such as the band 20 is inserted, and this mounting part 13 is a base that becomes a point of effort when operating the operating body B in a swinging operation. The edges are formed. Reference numeral 15 denotes a notch provided in the lower edge portion of the locking piece 11 in order to improve the grip on the band 20 etc. which are pressed between the surface of the substrate 1 and the lower edge portion of the locking piece 11.

The present invention is constructed as described above.Next, its use will be explained.In order to attach the operating body B to the base body A, first, the protrusion guide groove 4 on one side of the base body A is
One locking protrusion 12 of the operating body B is housed in an upright state and tilted obliquely with respect to the base body A. Next, the other locking protrusion 12 is pushed into the protrusion passing recess 5, and then forcibly pressed so as to go over the protrusion stop step 6 to be accommodated in the other protrusion guide groove 4, and the shaft rod 3 is It is assembled by being accommodated in the shaft accommodating groove 10.

Then, when the operating body B is swung around the shaft 3 to stand up with respect to the base body A, the locking piece 1
1 is separated from the surface of the substrate 1, and the clamping state between the substrate 1 and the locking piece 11 is released. At this time, the locking protrusion 12 of the locking piece 11 of the operating body B comes into contact with the protrusion stop step 6 that forms the edge of the protrusion guide groove 4 of the left and right rising pieces 2, and further swinging is prevented. , prevents the shaft rod accommodating groove 10 and the shaft rod 3 from being disengaged from each other. Further, when the operating body B is swung to lie down relative to the base body A, the lower edge portion of the locking piece 11 is pressed against the surface of the base plate 1, and the band 20 and the like can be held between them.

In addition, in order to attach the operating body B to the base body A, as shown in FIG.
Using the operating body B having the groove 16, this empty groove 1
6 to forcibly elastically deform the operating body B so that the locking protrusions 12 approach each other, and the locking protrusions 1
2 may be fitted into the protrusion guide groove 4. At this time, the operating body B can be easily attached to the base A in which the protrusion passing recess 5 is not provided. especially,
Even if it is made of a material that is difficult to deform, such as hard plastic, it can be assembled easily and the root portion of the locking projection 12 can be prevented from being damaged.

(Effects of the Invention) Therefore, the present invention provides a substantially rectangular front frame by vertically disposing left and right rising pieces 2 on both sides of a substrate 1, and horizontally connecting a shaft rod 3 at the upper end of each of the left and right rising pieces 2. A synthetic resin base A integrally formed in a shape, and a rod accommodating groove 10 having a substantially U-shaped cross section capable of accommodating the rod 3 are recessed in the upper surface near the tip. A synthetic resin operating body B is attached to the base body A so as to be able to swing freely in an up-and-down manner around a shaft rod 3 that fits within the space of 10.
and is formed so that when the operating body B is in a laid down state with respect to the base body A, an object to be held such as a band 20 can be held between the base plate 1 of the base body A and the locking piece 11 at the tip of the operating body B, When the operation body B is in an upright state with respect to the base body A, a protrusion guide groove is formed so that the clamping state between the base plate 1 and the locking piece 11 is released, and is recessed on the inner side surface of each of the rising pieces 2. 4 and locking piece 1
Locking protrusions 12 protruding from the upper part of both side ends and movable within the protrusion guide groove 4 regulate the swinging range of the operating body B relative to the base body A, and the shaft rod housing groove 10 and the shaft rod 3 are connected to each other. Since the engagement state of the base body A and the operation body B are formed so as not to be released, the strength and rigidity of the base body A and the operation body B themselves can be sufficiently increased, and even if they are made of synthetic resin, they will not easily deform or break. There will be no danger. Moreover, the overall strength of the fastener is extremely high, and it is robust and does not easily disassemble or get damaged, and can exert a reliable and strong clamping force.

In addition, a synthetic resin base A and a synthetic resin operating body B
Since the base body A and the operating body B can be formed separately and assembled later, the manufacturing and assembly operations are extremely easy, and the band is small and lightweight and has excellent flexibility. This makes it possible to provide fasteners at low prices.

In particular, since the base body A is integrally formed with the base body 1, the left and right rising pieces 2, and the shaft rod 3 into a substantially rectangular frame shape from the front, the rising pieces 2 are less likely to be broken from their roots, and the lack of strength of the rising pieces 2 is prevented. It will be possible to resolve it.

Furthermore, the operating body B is formed by the shaft 3 and the shaft accommodating groove 10.
Since it is configured to swing relative to the base A,
When the operating body B is in a reclining state with respect to the base body A, the upper end portion of the rising piece 2 does not protrude upward from the upper surface of the operating body B, and even if it comes into contact with the body, no discomfort is caused, and the stopper It is possible to reduce the overall thickness, and the appearance is also good.

Since a protrusion guide groove 4 recessed on the inner side surface of each of the rising pieces 2 and locking protrusions 12 protruding from the upper portions of both side ends of the locking piece 11 are provided, the operation body B can be swung relative to the base body A. The range of movement can be restricted, and when the operating body B is in an upright state with respect to the base body A, the shaft rod accommodation groove 1
0 and the shaft rod 3 is released, and it becomes possible to reliably prevent the operating body B from deviating from the base body A.
