[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a hem stop belt that is used by directly tightening shirts on the waist to prevent the shirts from rising up.

[0002]

[Prior art and problems to be solved]

 Normally, when wearing shirts such as shirts, the hem of the shirt is placed inside the waist of the trousers and fastened with the belt of the trousers to secure the hem of the shirt. However, walking or exercising can cause shirts to slip up and make them unsightly. To prevent this, some shirts are fastened directly to the waist or hem to secure them to the body. This belt is made of soft and flexible elastic rubber, and has a large number of holes and projections penetrating into the holes formed integrally and alternately at equal intervals on the surface thereof. When this belt is tightened and used, both ends of the belt are overlapped and the protrusion on one end is engaged with the hole on the other end while pulling the belt that is rotated from above shirts to the waist. Therefore, the belt can be fastened to the waist and is made of elastic rubber to prevent the hem of shirts such as shirts from rising due to body movements.

In the conventional hem-stop belt, if the upper end of the overlapping portion of the belt is disengaged during use, the belt loosens. To prevent this, the end of the belt is prevented. A separate stopper was mounted on the belt, and the stopper was fitted into the above-mentioned engaging hole of the belt to fix the end portion of the belt. The conventional stopper has a collar at each end of the shaft.To insert this shaft into the hole at one end of the belt and fix this end to the other end, It is necessary to push it in while spreading this brim into the hole on the other end side of the belt with your fingertips, and it requires force and force on your fingertips to fix the stopper, which is a drawback that you cannot easily and quickly attach it. It was Further, in the conventional belt, if the end portions are not firmly fixed in this way, there is a risk that the belt may come loose and loose during use such as sports and exercise.

In view of the above problems, the present invention is a shirt in which the engagement at the time of stacking the belts can be performed easily and reliably, and the end portions of the belts can be reliably fixed. The purpose is to provide a belt for preventing similar types of skid.

[0005]

[Means for Solving the Problems]

 According to the present invention, there is provided an engaging step in which a soft elastic rubber belt is provided with engaging holes penetrating the belt and engaging protrusions projecting to the surface side of the belt, which are alternately arranged in the longitudinal direction at regular intervals. A plurality of rows are integrally provided, and the engaging projection has a head whose diameter is expanded in a taper shape so that it can be inserted into the engaging hole at the tip of its shaft, and a hollow hole is formed inside from the end face of the head. Form .

[0006] Thus, when the both ends of the rubber belt are pulled and overlapped when the belt is used, the engaging protrusion of the lower belt and the engaging hole of the upper belt at the overlapping portion are inserted and removed. When the belt is in use, the head protruding from the upper surface of the belt locks the inner edge of the engaging hole, so that the engaging projection and the engaging hole are securely locked. .

As described above, according to the present invention, it is possible to easily insert and remove the engaging projection into and from the engaging hole, and to ensure the engagement, and further, to further secure one end portion or both end portions of the belt. An end fixing projection is provided on the back surface side, and it is integrally formed as a projection having a tapered head portion whose diameter is expanded to be approximately the same diameter as the above engagement hole in the belt surface area at the tip thereof. A hole is also cut out from the end face of the head. This prevents the disengagement of the belt from the end of the upper belt, and at the same time, makes it easy to reduce the diameter by the hollowed hole, which facilitates the removal. In this way, both easy and easy insertion / removal into / from the engagement hole and reliable engagement / fixation of the end portion are achieved.

In the manufacture of the belt, it is convenient to use a mold to form a melted and softened rubber material by injection molding to integrally form the belt. Since the constant protrusion has an enlarged head, the protrusion axis becomes an undercut, and when releasing from the mold gap where the protruding shape is formed after casting, the head hinders die cutting. , I was afraid my head would be cut off. According to the present invention, the diameter of the head is increased in a taper shape, and by forming a hollow hole in the head, when the head passes through the undercut portion of the mold at the time of mold release, the head is hollowed out. The holes elastically reduce the diameter of the rubber to make it easier to pull out and prevent the head from being left uncut in the mold, thereby realizing belt integral molding using the mold such as injection molding.

By thus improving the shapes of the engaging projections and the end fixing fasteners, the belt can be easily attached to and detached from shirts, and moreover, the belt can be securely lifted. Effectively preventing it, it is possible to prevent accidental detachment of the belt and the accompanying protrusion of shirts even when it is used for intense exercise such as sports.

[0010]

[Embodiment of the invention]

 The belt of the present invention will be described below with reference to the drawings. FIG. 1 (A) shows a plan view of the belt 1. The belt is integrally formed of soft elastic rubber, and normally the waist portion of the body is The length is set to an appropriate length so that the ends can be overlapped by winding.

In the surface area of the belt 1, three rows of engaging means 2 and 3 are formed in the longitudinal direction. The engaging means 2 and 3 include an engaging hole 2 penetrating the surface of the belt 1 and a belt. Engaging projections 3 projecting from the surface of 1 are arranged in a row alternately in the longitudinal direction at equal intervals. Between adjacent rows, the engagement protrusion 3 and the engagement hole 2 are arranged so as to be adjacent to each other. The reason why the engaging means 2 and 3 are formed in three rows is to prevent the engaging means 2 and 3 from being disengaged due to the distortion of the belt.

As shown in the surface of FIG. 1 (B), the engagement protrusion 3 is provided on the front surface 10 of the belt 1, and its shape is expanded to the end of the protruding shaft 31. The head portion 32 has a smaller diameter than the engagement hole diameter so that the head portion 32 can be loosely fitted in the engagement hole 3, but is enlarged in diameter than the shaft 31. The head 32 has a tapered diameter, and has a hole 33 that is hollowed inward from its end. Since the hollowed holes 33 are provided and the material is elastic rubber, the tapered head portion 32 can be elastically contracted in the radial direction.

The hollowed-out hole 33 is opened in the end face of the head 32, and the hole shape is substantially semi-ellipsoidal in this example, and the bottom thereof is stopped until reaching the shaft 31. It The hole shape may be an inverted conical shape or a hemispherical shape. The point is that, during the belt manufacturing process, the head 32 is elastically shrunk by the hollowed hole 33 during the die cutting after the casting of the belt. It suffices that the belt is extended and reduced in diameter so that the head 32 can be easily pulled out by passing through the shaft undercut portion in the mold and the mold release of the belt molded product can be surely performed.

As shown in FIG. 1 (C), a large number of small anti-slip projections 4 are formed on the back surface of the belt 1 along the entire length in the longitudinal direction so as to project in a trapezoidal or conical cone shape. When the belt 1 is used, the tips of the small anti-slip projections 4 abut the cloth surface of shirts to prevent the shirts from slipping off and to prevent the shirts from being rubbed up. The small anti-slip projections 4 are formed at the back side positions corresponding to the engaging projections 3 on the front surface side. This is for allowing the lower belt to be accommodated in the engagement hole 2. This prevents the small anti-slip projections 4 from coming into contact with the back side belt surface and forming a gap between the upper and lower belts at the overlapping portion.

Further, although FIGS. 2A and 2B show the end 12 of the belt 1, the end 12 of the back surface 11 is provided at a position corresponding to the engaging projection 3 in the central row. An end-fixing projection 5 is integrally formed so as to project. The end-fixing projection 5 is a taper-shaped expanding head that can be fitted with an outer diameter substantially the same as the hole diameter of the engaging hole 2. 52, and the head portion 52 of the end fixing projection 5 has a hollowed hole 53 formed inside from the end portion.

The hollow hole 53 of the end fixing projection 5 is opened on the end face of the head, and the shape of the hole is an inverted conical shape, a hemispherical shape, or a semi-ellipsoidal shape, and the bottom of the hole 53 is a shaft. Those that stop until 31 are formed. Also in this example, the hole shape is substantially a semi-ellipsoidal shape, as in the case of the engaging projection 3. The hollow portion 53 of the end fixing projection 5 also has a head portion 32 that is elastically elastically contracted and stretched to reduce the diameter when the belt is cast after casting. It suffices that the head 32 can be easily pulled out after passing through the cut portion, and the demolding of the belt molded product can be surely performed.

FIG. 3 shows a cross-sectional view (A) and a plan view (B) when the belt ends 12 and 13 are overlapped with each other when the belt is used. Occasionally, the engaging protrusions 2b ... Of the lower end 13 of the overlapping portions 15 of the both ends 12, 13 of the belt 1 are inserted into the engaging holes 2a of the upper end 12. Be locked. At this time, since the belt 1 is overlapped in a tensioned state, tension acts on the upper and lower belt ends 12 and 13, and in addition, in a tensioned state, the tapered surface of the enlarged head portion 32 of the engagement protrusion 3b is engaged. It engages with the inner peripheral edge 21 of the fitting hole 2a, making it difficult for the overlapping portion 12 to come off. For this reason, the engaging means 2 and 3 need to be formed on at least both ends 12 and 13 which are overlapped during use, but are formed on the entire length of the belt 1 including both ends 12 and 13. Good.

In the sectional view of FIG. 3A, the belt end portions 12 and 13 on both sides of the overlapping portion 15 are pulled straight, but in actual use, the belt is It is curved with a curvature around the waist or abdomen of the body. Then, in the overlapping portion 15, the end fixing projection 5 is engaged by selecting and inserting an appropriate engaging hole 2b capable of appropriately applying tension to the belt 1 when tightened on the body. As a result, it is possible to prevent the belt 1 from coming off from the upper end 12 of the belt 1. Furthermore, since the end-fixing projection 5 has the cut-out hole 53, it can be easily reduced in diameter as an elastic rubber, so that the projection 5 that is penetratingly engaged with the appropriate engaging hole 2b during use is If the upper end portion 12 of the belt 1 is strongly pulled forward with respect to the body by the hand, it is easily disengaged from the engaging hole 2b, and the belt can be easily detached.

In the manufacture of the belt 1 of the present invention, a melting mold of the raw material is placed in a mold (not shown) in which the shape on the front surface 10 side and the shape on the back surface 11 side of the belt 1 are formed on the inner surface of the mold. It is possible to use an injection molding method of injecting under pressure and releasing after solidification. In this case, both the engaging projection 3 and the end fixing projection 5 have the tapered head portion 52, which is expanded in diameter with respect to the shaft, as described above, and the hollow 53 is formed inward from the end surface. Therefore, the head 52 can be easily pulled out from the mold, the mold release of the belt molded product can be surely performed, and mass productivity by the injection molding method can be realized.

[Effect of the invention]

 The present invention is a hem-stopping belt in which engaging means consisting of an engaging hole on the surface of a belt and an engaging projection protruding on the surface of the belt are repeatedly formed, and the engaging projection has a tapered diameter. Since a head part that can be inserted into the engaging hole is provided, it is possible to easily insert the engaging protrusion into any desired engaging hole and to ensure the engagement thereof. It can effectively prevent loosening and coming off.

Further, an end fixing protrusion is provided at one end on the back side of the belt, and a tapered diameter-expanded head is formed so that the protrusion can be inserted into any engaging hole, so that the belt end is fixed. It is possible to prevent the belt from coming loose from the end portion.

Furthermore, since both the engaging projection and the end fixing projection have hollow holes formed in the tapered head, the mold release is easy in the die molding such as the belt injection molding. However, this makes it possible to facilitate integral molding and enable mass production even for a belt having a complicated projection shape.
