Description

The invention relates to sports equipment, in particular to the structural element of the fixed gates for ball games.

The connecting element of the gate design for ball games is known (see, for example, the patent for a useful model JPS 62145671 U according to class А63В 63/02 with priority from 11.03.1986). To connect the bar and the horizontal crossbar of the gate during assembly, a massive L-shaped element in terms of shape is used, the ends of which are installed in the cavity of the rack profiles and crossbars and fixed with bolts. The disadvantages of this design can be attributed to the large details, greater consumption of materials and excessive complexity of the design.

The design of the gate for ball games is well known (see, for example, patent for utility model CN 207203360 U in class А63В 63/00 with priority from 09/21/2017). To assemble the rod and the horizontal crossbar of the gate, the assembly uses a three-dimensional L-shaped element in terms of shape, the ends of which are installed in the cavity of the rack and crossbar profiles and fixed with bolts and a flat applied L-shaped element in terms of shape. The disadvantages of this design can be attributed to the large details, greater consumption of materials and excessive complexity of the design.

The connecting element of the gate design for ball games is known (see, for example, patent for utility model CN 207203361 U in class А63В 63/00 with priority from 09/21/2017). To connect the rod and the horizontal crossbar of the gate during assembly, a volume element approximately L-shaped in terms of shape is used, the ends of which are installed in the cavity of the stem and crossbar profiles. The disadvantages of this design include the excessive complexity of manufacturing the connecting element.

The purpose of the utility model is to simplify the design of the connecting element of the gate, its manufacture and installation, as well as reducing material consumption.

For this, the horizontal and vertical sections of the gate connecting element, made L-shaped in plan and intended to connect the ends of the crossbar and the rack, have at least a portion of their length a U-shaped cross section, and are also provided with through holes for the passage of fasteners the holes are located symmetrically about the axis O-O. The horizontal and vertical sections of the gate connecting element can be equal in length.

Due to the implementation of the connecting element U-shaped cross-section, it turns out quite tough. The connecting element during installation is superimposed on the corresponding ends of the rod and crossbar. By making the through holes for the passage of fasteners symmetrically about the axis O-O, the unification of the right and left connecting elements is achieved.

Through holes of the connecting element, designed for the passage of fasteners, can be made not only round but also square cross-section under the corresponding base of the bolt head, which simplifies the assembly, which requires only one tool - a key for a nut.

The connecting element can be made by cutting a pattern from steel sheet with its subsequent bending and welding. The optimum thickness of the steel sheet is in the range from 1.5 to 5 mm.

The connecting element can be made by welding two parts made of a channel with parallel edges of the shelves.

The design of the gate can contain the following main elements: left and right side supports, coupler 1 and crossbar 2. Side support contain base 3, rod 4 and arc 5 (see Fig. 1). In order to unify, the left and right side supports can be made the same. When mounting the gate, the crossbeam 2 is connected to the side supports by means of connecting elements 6 and fasteners 7, made, for example, in the form of bolts (see Fig. 3). In order to unify, both connecting elements 6 can be made the same. The rods 4 and the crossbar 2 can be made of a square or rectangular profile. The connecting element 6 is made L-shaped in plan, and its horizontal and vertical sections at least part of their length have a U-shaped cross-section and contain through holes 8 for the passage of fasteners 7. Holes 8 are located symmetrically relative to the axis O-O of the connecting element 6. By making the through holes 8 for the passage of the fastening elements 7 symmetrically about the axis O-O, the unification of the right and left connecting elements 6 is achieved.

Due to the implementation of the connecting element 6 U-shaped cross-section, it turns out quite tough. When mounting, the connecting element 6 is superimposed on the corresponding ends of the rod 4 and the crossbar 2. To simplify installation, the through holes 8 for the passage of fasteners 7 can be made of square cross-section under the corresponding base of the bolt head, so that only one tool is required for assembly under the nut 9.

The connecting element 6 can be made either by cutting a pattern out of sheet steel with its subsequent bending and welding (see Fig. 4 - Fig. 7), or by welding two parts made of a channel with parallel edges of the shelves (see Fig. 8 - Fig. 10). Since the gate can be used to play mini-football, a color coating is applied to the surface of the connecting element 6 corresponding to the markings of the corner portion of the gate in this sport.

Thus, the simplification of the design of the connecting element of the gate, its manufacture and installation, as well as the reduction of material intensity.
