Hereinafter, a hurdle bar attachment according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. However, the technical scope of the present invention is not interpreted to be limited in any way by the embodiments described below.

First Embodiment
The configuration of the hurdle bar attachment 1 of this embodiment is shown in detail in Figures 1 to 5. Figure 1 is a perspective view of a hurdle 100 to which a pair of hurdle bar attachments 1 are attached, Figure 2 is an exploded view of the hurdle bar attachments 1 removed from the base 2 of the hurdle 100, and Figures 3 to 5 are various views of the hurdle bar attachment 1.

As shown in FIG. 1, the hurdle 100 has two left and right columns 21 erected on a base 2. A pair of hurdle bar attachments 1 are attached to the upper portions of two pillars 21, respectively. Details of the hurdle bar attachment 1 will be described later, but by simply attaching a pair of hurdle bar attachments 1 in place of the plate hurdle bar B (Fig. 11), the hurdle 100, which originally had a plate hurdle bar specification, can be opened and closed. Remake to type hurdle bar specification.

As an example, the two supports 21 have a double tube structure consisting of a circular tube-shaped inner tube 21a and a similarly circular tube-shaped outer tube 21b. The inner tube 21a can slide up and down relative to the outer tube 21b, making it possible to adjust the height of the bar. After adjusting to a predetermined height, the bar is fixed at that height by, for example, inserting a stopper pin into through holes in the inner tube 21a and the outer tube 21b (not shown). The supports 21 are not limited to being circular tube-shaped, and may be square tubes, etc.

The base 2 includes a connecting rod 22 that connects the two columns 21 at the bottom, and horizontal bars 23 that extend rearward from the bottom of each column 21. Thereby, when the user's foot gets caught, it will fall in the direction of the user's movement.

Furthermore, since this hurdle 100 was originally designed as a plate-shaped hurdle bar, there is a bar receiver 24 on the upper part of the support column 21, which is an attachment part for the plate-shaped hurdle bar B (see FIGS. 2 and 4). As an example, the bar receiver 24 has a configuration in which two clamp-type mounting fittings 24a arranged facing each other are connected by a pedestal 24b on the bottom side. The inner cylinder 21a of the support column 21 is connected to the bottom surface of the pedestal 24b. The bar receiver 24 and the inner cylinder 21a are made of metal such as iron or stainless steel, and are formed by welding or integral molding. The two clamp-type mounting fittings 24a have through holes 24c through which fixing means such as bolts or screws are passed. This through hole 24c was also originally provided for fixing the plate hurdle bar B (see FIG. 11).

As shown in FIGS. 3 to 5 in detail, the hurdle bar attachment 1 includes a socket 10 that fits into the bar receiver 24 from above, a hurdle bar 11 that extends laterally from the upper side of the socket 10, and the socket 10 and the hurdle bar. 11, and a safety cover 13 that covers the upper side of the socket 10. Note that the pair of hurdle bar attachments 1 have the same structure except that they are attached so as to face each other.

The socket 10 is formed, for example, from a square tubular member. The socket 10 is open at the bottom side, and the opening at the top side is blocked by, for example, a safety cover 13. It may be blocked with another member and then covered with the safety cover 13. The shape and size of the socket 10 are such that the inner surface of the socket 10 and the outer surface of the mounting bracket 24a of the bar receiver 24 face each other (Figure 5). The inner surface of the socket 10 and the outer surface of the mounting bracket 24a of the bar receiver 24 may be in contact with each other or there may be a small gap between them as long as they are slidable. An elastic material such as rubber may also be interposed between them.

The socket 10 is in the shape of a cap that is fitted to cover the entire mounting fitting 24a of the bar receiver 24, for example, to a position where the opening on the lower end side of the socket 10 is closed by the pedestal 24b. A through hole 10a is formed in the side surface of the socket 10 (FIG. 4). Then, they are aligned with the through holes 24c of the mounting fittings 24a, and can be fixed to each other using fixing means 12d such as bolts and nuts. Other fixing methods may also be used. The socket 10 is made of metal such as iron or stainless steel. Therefore, it is covered with a safety cover 13. The safety cover 13 is made of an elastic member such as resin or rubber. However, the socket 10 may be made of any material such as resin. That is, the material is not particularly limited. The safety cover 13 may be omitted by making it made of resin.

As shown in the cross-sectional view of FIG. 5, the hurdle bar 11 is, for example, a soft hurdle bar in which a hollow soft cover 11b is placed over a cylindrical core 11a. FIG. 5 also shows an example of the size (unit: mm) of each member. The core material 11a is preferably a relatively lightweight metal bar such as aluminum, but is not limited thereto. The soft cover 11b is a cover made of an elastic member. The soft cover 11b is made of, for example, resin foam. An example of a resin foam is a polyolefin foam. The hurdle bar 11 has its proximal end connected to the upper side surface of the socket 10 by a connecting portion 12 . The connecting portion 12 is, for example, a spring member 12a that connects the core material 11a and the socket 10. One end of the spring member 12a is fixedly connected to the core member 11a by a fixing member 12b. The other end of the spring member 12a is passed through a through hole formed in the side surface of the socket 10, and fixed to the socket 10 using fixing means 12d (see FIGS. 2 and 3) such as bolts and nuts. However, the connection structure is not limited to this. The spring member 12a is covered with a cover 12c formed by connecting a plurality of resin pieces into a bellows shape. The resin top is made of plastic, for example.

According to the hurdle bar attachment 1 having the above-described structure, the hurdle 100, which has a plate-shaped hurdle bar specification, can be replaced by simply fitting the socket 10 into the bar receiver 24 from the upper side and fixing it with the fixing means 24d to prevent it from coming off. can be remade into an opening/closing hurdle. The hurdle bar 11 is connected by a spring member 12a, so that the hurdle bar 11 can be bent in any direction using the root portion as a fulcrum. Therefore, as illustrated in FIG. 6, even if the user's foot or the like hits it, the user can avoid falling over. Furthermore, the outer surface of the socket 10 except for a part of the lower part is covered with an elastic material, ensuring safety so that the user will not be injured even if his or her foot hits it.

(Second embodiment)
Next, the hurdle bar attachment 1 of the second embodiment will be described with reference to FIGS. 7 to 10. The size of the bar receiver 24 is not standardized due to standards or the like, and the width (L1), depth (L2), and height (L3) shown in FIG. 7 may differ. As an example, FIG. 7 shows a bar receiver 24 (FIG. 7(a)) with a wide width (L1) and a short depth (L2), and a bar receiver 24 (FIG. 7(a)) with a narrow width (L1) and a long depth (L2). (b)) is shown. The hurdle bar attachment 1 of this embodiment is an embodiment in which the socket 10 is improved so that the bar receivers 24 can be attached to hurdles 100 having different sizes.

In the present embodiment, the socket 10 is configured with a body part 10b and a lid part 10c in the portion that fits into the bar receiver 24. The body part 10b and the lid part 10c are formed in a U-shape with the surfaces in which the through hole 10a is formed facing each other, allowing the lid part 10c to be freely fitted into the body part 10b. The lid part 10c is formed so that when attached to the body part 10b, the inside of both sides of the lid part 10c face the outside of both sides of the body part 10b, preferably in surface contact. However, a slight gap may be present, or an elastic material such as rubber may be interposed. The body part 10b and the lid part 10c may be formed of any material, such as metal or resin, for example. In other words, there is no particular limitation on the material.

The main body part 10b and the lid part 10c are each provided with steps 10d at the corners on both sides of the U-shape. The step 10d of the main body side part 10b and the step 10d of the lid part 10c have a symmetrical structure in which they face each other. As shown in FIG. 9(a), for the bar receiver 24 shown in FIG. 7(a), which is wide in width (L1) and short in depth (L2), the step 10d is in contact with the mounting bracket 24a. come into contact with In addition, as shown in FIG. 9(b), for the bar receiver 24 illustrated in FIG. 7(b), which is narrow in width (L1) and long in depth (L2), the surface on which the through hole 10a is formed is attached to the mounting bracket. 24a. Thereby, the socket 10 can be attached to either bar receiver 24 without loosening. Note that since the socket 10 is hollow inside, the difference in height (L3) does not pose any particular problem.

As shown in FIG. 10, in the hurdle bar attachment 1 of this embodiment, the main body part 10b is first fitted into the bar receiver 24 from, for example, the upper side or the side, and then the lid part 10c is fitted from the side, for example. mating from. Then, the through hole 24c of the mounting bracket 24a, the through hole 10a of the main body side part 10b and the lid part 10c are aligned, and fixed to each other using fixing means 12d such as bolts and nuts. Other fixing methods may also be used. The other hurdle bar attachment 1 is attached in the same manner. As described above, the hurdle bar attachment 1 of this embodiment can be attached to hurdles 100 with bar receivers 24 of different sizes. Moreover, this is realized by a simple configuration in which the socket 10 is divided into a main body part 10b and a lid part 10c, and an increase in the number of parts is also suppressed. Note that the socket 10 of the first embodiment may be provided with a step 10d. The step 10d is not limited to being formed on the part itself, but may be formed by fixing another member.

The hurdle bar attachment 1 of the above-described embodiment can be used for hurdle competitions, track and field, and class competition training, and can also be used for training to acquire the rhythm of flying while running, such as the number of steps and stride length, and for jumping games. Also, changing to soft hurdle bars has the effect of alleviating children's fear of hurdles. In addition. Retractable hurdle bars are not limited to soft types. Further, the bar portion may be of a type other than a circular bar.

Although the present invention has been described in detail in accordance with the specific embodiments above, various substitutions, modifications, changes, etc. in form and details may be made to the invention as defined by the claims of the utility model registration. It will be apparent to those of ordinary skill in the art that modifications may be made without departing from the spirit and scope of the invention.
