JPS5819312B2 - Pillar upright ball protection net - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ball-prevention net that protects private houses from the danger of flying balls in baseball and other sports.

Upright ball protection nets installed at schools, company grounds, etc. generally consist of wooden or concrete pillars, and steel wires are stretched between each pillar. However, since there is no space between the poles and the net, there is a risk that a player chasing a fly ball will collide with the poles, and the net is tied directly to the poles, causing friction. It has disadvantages such as being easily damaged and having poor appearance.

The present invention has been made in view of the conventional situation, and will be explained below with reference to the embodiments shown in the drawings. In Figs. As shown in the drawings and FIG. 4, the projecting metal fittings 2 are fixed with holding bands 3 at appropriate intervals in the front longitudinal direction.

Various forms of this overhanging metal fitting 2 can be considered, but in this embodiment, a grip 7 made of a horizontal steel wire is provided at the bottom of the horizontal steel wire grip 7, and a vertical steel wire is attached to the lowermost and topmost overhanging metal fittings 2. A vertical steel wire fastener 8 is attached to the upper part of the intermediate overhanging metal fitting 2 to connect the reel 3.
are installed in one piece.

A vertical steel wire 4, such as a steel wire, is hung between the upper and lower reels 3 and 3, and the intermediate portion thereof is tightened and fixed by a fastener 8 integrated with the overhanging metal fitting 2, and the adjacent column. 1 overhang metal fitting 2
The two are connected by a horizontal steel wire 5 such as a steel strand.

In the example, the uppermost horizontal steel wire is connected by the reel 9 (FIG. 6), and the other horizontal steel wires are connected by the grip 7 (FIGS. 3 and 4). It is.

Further, a net 6 is attached to the space in which the vertical and horizontal steel wires 4 and 5 are stretched by tightening its edge rope 6a to the steel wires 4 and 5 (FIG. 1).

The ball protection net of the present invention is constructed as described above,
The net 6 is indirectly attached by extending forward from the surface of the column 1 by the overhanging fitting 2, and the vertical steel wire 4 suspended between the upper and lower reels 2a is spaced from the column 1 in the vertical direction in front of the column 1. Because the net 6 is placed so that it hangs in front of the pillar, its repulsive force prevents the contestant from colliding with the pillar itself, and the durability of the net 6 is maintained without damaging the net 6 due to friction with the pillar 1, thereby protecting private houses. Fulfill your purpose to the fullest.

Needless to say, it is excellent in appearance.

Although it costs a little more in construction time and the number of parts, it is economically more advantageous considering that expensive nets can be used semi-permanently.
