Description

  The present invention relates to a stopper for fixing a side edge of a net used for badminton, tennis, volleyball competition, and the like to a column.

  In general, as shown in FIG. 10, for example, a badminton net will be described. When the net body 1 is stretched between two struts 5 installed in the center of the coat, a plurality of net side edges 4 are provided on the net side edge 4. Each string 12 is tightly tied, and the string 12 is used as a fastening means for the net side edge 4 and the support column 5 and is fixed to the support column 5 so as not to form a gap.

  Further, as disclosed means for fastening means for fastening the net side edge 4 to the column 5, there are, for example, Japanese Patent Laid-Open Nos. 7-275415 and 2004-24885. Among these publications, as shown in FIG. 8, Reference 1 is a velvet that is integrated with the net side edge portion 4 and has an engaging portion and an engaged portion that can be engaged with each other and can be fixed by the engagement. Fastening to the support column 5 is performed by a winding part 17 provided with a fastener 8.

JP-A-7-275415 JP 2004-24885 PR

  However, according to the above technique, when the winding part 17 of FIG. 8 is fixed, for example, in the badminton net, the covering band 13 or the like for fixing the winding part 17 is not originally provided on the net side edge part 4. Therefore, even if the manufacturing cost increases and the attachment / detachment is repeated every day, the velvet fastener 8 portion is damaged, and even if the engaging force is reduced, only the winding portion 17 cannot be replaced.

  Further, when the fastener 19 is not fixed as shown in FIG. 9, for example, when the fastener 19 that has been fastened is removed, the fastener 19 is not fixed. There is a possibility that it will fall off the net side edge 4 and be lost. In addition, the fastening can only be done after releasing the one that has been fastened.

  Further, when the fastening is released and fastening is performed so that the fastener 19 is left on the net 1 side, even if one fastener is removed, the other fasteners are fastened. There are not so many gaps, and it is difficult and difficult to fasten one end of the removed fastener through the narrow gap, and if it is fastened to the mesh side of the net, There are restrictions on the location and number of velvet fasteners 8 attached.

  From the above, when the fastener 19 is fixed, the work is one-touch, but partial replacement due to damage is not possible. When the fastener 19 is not fixed, basically, the fastener 19 is stopped again after the fastener 19 is released. Since wearing work occurs, a series of work is two-touch, and there is a problem that characteristics as a fastener using velvet fasteners are not utilized.

  The present invention has been made in view of such problems, and the problem is that a series of operations in fastening and releasing of the net side edge to the support can be quickly and easily performed, and velvet is obtained by repeated use. It is a point to provide a ball game net stopper that is compatible with the characteristics of a stopper using a velvet fastener, and that the lowered stopper can be partially exchanged against a decrease in the engagement force of the fastener. . In addition, in the holding means between the stopper and the net side edge portion as required, it is also possible to make the attachment constant and to prevent the holding portion from becoming thicker than necessary, and to simplify the holding means.

  In order to solve the above-described problems, the technical means of the present invention includes a net side edge portion of a ball game net stretched between support columns provided at the left and right of the center of the ball game field, and the support column. A ball game net stopper that is wound and fastened with a velvet fastener that has an engaging portion and an engaged portion that can be engaged with each other at both ends of the stopper, and can be fastened by the engagement. The tool can be fastened by winding the side edge portion and the column. And it has a holding means which prevents that this stopper falls off from the said net side edge part by cancellation | release of this fastening.

  Then, either one of the engaging part and the engaged part of the velvet fastener is attached to the center of the wide surface of the stopper, and the other of the engaging part and the engaged part of the velvet fastener is attached. The side edge portion is sandwiched with a belt-shaped member to serve as a holding means. Further, if necessary, the velvet fastener attached to the center of the wide surface of the stopper is connected to the engaging portion and the engaged portion. Either one of them is attached with a certain interval, and two of the engaging part and the engaged part of the velvet fastener are attached to the belt-like member with a certain interval. And, by attaching the side edge part along the gap created by the adhesion of each velvet fastener, and fixing it, the attachment can be made constant, and the place where it is held without being affected by the thickness of the velvet fastener is more than necessary. It was set as the structure which does not become thick.

  Further, if necessary, it is effective that the central portion of the stopper is a string-like member or a strip-like member, and the stopper is passed through the net of the net, and if necessary, the center of the wide surface of the stopper. It is also effective to provide a cut portion at a predetermined location on the side toward the longitudinal center line from both longitudinal sides. In addition, it is effective to provide a flexible magnet material on the back surface on the side where the engaged portion of the velvet fastener is attached to one end of the stopper, and if necessary, a velvet is provided on one end of the stopper. It is particularly effective to provide an ear portion in which the side to which the engaged portion of the fastener is attached is wider than the width of the other end side.

  According to the ball game net stopper of the present invention having such a configuration, according to the first to third aspects of the invention, when the ball game net is attached to the support, the net is bridged between the support, The gap at the side edge cannot be formed because a stopper held at the edge on the net can be wound around the support and fastened with velvet fasteners attached to both ends of the stopper. In this case, since the operation can be performed with one touch, the operation is easily performed. In addition, when removing this ball game net, it is only necessary to release the engagement of the velvet fastener, and even after the release, the holding means provided on the stopper prevents the stopper from dropping off from the edge of the net. Just like the time, you can do one-touch work.

  According to the invention described in claims 4 to 6, the net side edge is formed in each gap formed by the two velvet fasteners attached to the stopper and the two velvet fasteners on the belt-like member side, which are holding means provided on the stopper. By being able to hold the parts along and hold them together, all of the stoppers can be held at certain locations, and the portions held without being affected by the thickness of the velvet fasteners do not become thicker than necessary. In addition, by using only a string-like or narrow strip-like member at the central portion of the stopper, the holding means only needs to bend one end of the stopper with a finger or the like and pass it through a net mesh, If the shape or the length of the side in contact with the string-like member is longer than the diagonal length of the first mesh of the net, or if the shape is larger than the first mesh, it is once passed if it is not bent by hand. After that there is no worry of dropping out. Further, when a cut is provided in the central portion of the stopper, the structure and the mounting are simple and easy because the cut can be held at the net side edge simply by inserting each other.

  Furthermore, in the invention described in claims 7 to 8, a flexible magnet material is provided on the one end side of the stopper on the side to which the velvet fastener engaged portion is attached, so that it can be wound depending on the nature of the magnet. At this time, it is fixed by suction with the support column, and the side of the stopper to which the velvet fastener engaging portion is attached can be hung with one hand and fixed. Also, in the ear provided on the stopper, when the stopper is wrapped around the column, the one provided with the ear is wrapped around, and the ear is fixed to the holding column with the finger and overlaps the pressed finger. It is very convenient because it can be wrapped around the other and fastened.

  With the holding means provided, there is no fear of the stopper falling off when attaching and removing the net, and unlike the case where the stopper is a string, the engagement force is caused by damage to the velvet fastener part due to repeated attachment and removal work. Even if it drops, it is possible to exchange only that part, so it is not necessary to renew the net body at the same time, and it is very economical.
