Description

The utility model relates to sports equipment, namely to the handles of collapsible sports bows.

A technical solution is known for a sports bow handle containing an emphasis, upper and lower parts of the handle made with through holes sequentially placed therein, with pockets at the free ends, characterized in that internal stiffeners are located between the front and rear surfaces in both parts of the handle at an angle so that the through windows form the shape of triangles, while the sides of the pockets are formed by solid walls (patent 174798, F41B 5/14, 02.17.2017).

A disadvantage of the known technical solution is not light enough, which affects the necessary stability when firing and saving power endurance (training) of archer athletes.

The technical result from the use of the proposed design of the handle is the ability to create a more lightweight handle with an excess safety factor.

The claimed technical result is achieved as follows.

The sports bow handle is made of high-strength aluminum alloy B95, sequentially processed by the forging method, from which the semi-finished handle is stamped, where metal molecules are formed into fibers in the shape of the product. The sports bow handle contains an emphasis 1, upper 2 and lower 3 parts of the handle made with through windows 4 sequentially placed in them. Pockets 5 with locks are made on the free ends of the handle for mounting the onion shoulders of various manufacturers.

Between the front and rear surfaces in both parts of the handle there are internal stiffeners located at an angle so that through windows form the shape of triangles and trapezoids with rounded corners. In this case, the sides of the pockets are formed through windows, forming stiffeners.

Advantageously, the handle through-windows have rounded corners.

Side surfaces of pockets have stiffeners.

In addition, the through windows of the side surfaces of the pockets located between the stiffeners are in the form of triangles and trapezoids with rounded edges.

Along with this, on the front and rear surfaces of the lower and upper parts of the handle, there are made longitudinal holes of rectangular shape with rounded edges.

The stiffening ribs of the handle pockets form the I-beam shape, and the stiffening ribs located between the front and rear of the handle form the Taurus shape.

The developed design of the handle of a sports bow using the topological optimization method provided the product with the lowest weight among analogues, the weight of the developed handle design is 840 grams and the deviation of the deformation of the shoulders during the shot is about 0.1 mm.

In FIG. 1 shows the onion handle, general view.

In FIG. 2 - onion handle, side view from the side of the sight mount.

In FIG. 3 - onion handle, view from the inside.

In FIG. 4 - bottom pocket of the onion handle, end view.

In FIG. 5 - upper pocket of the onion handle, end view.

The sports bow handle contains an emphasis 1, upper 2 and lower 3 parts made with through windows 4 sequentially placed in them. Pockets 5 for mounting the bow shoulders are made at the free ends of the handle.

In order to reduce weight and increase the rigidity of the handle design:

A through sample of 6 metal of the side planes of the pockets was made both on the right and on the left side in the form of triangles and trapezoids at the free ends of the handle;

Metal 8 was sampled at the location of the holes for the plunger in the form of a trapezoid with rounded corners;

Made a selection of metal 9 in the placement of the lining for the stop;

A through sample was made of a sample of metal 10 in the lower part of the handle above the lower pocket for mounting shoulders in the form of a triangle with rounded corners;

A through stiffener 11 is formed in the upper and lower part of the pockets in the form of a rectangle with rounded corners;

Formed stiffeners 12 in the lower part of the handle in the form of a triangle with rounded corners;

The pocket of the rear of the handle has a through window, rectangular with rounded edges, located parallel to the planes of the handle axes, forming a stiffener between the built-in pocket of the vibration damper on the inside of the handle of the sports bow;

Made a selection of metal on the lower protruding portion of the window 14 at the location of the shelf for the boom;

A selection of metal in pockets 15 was made, which made it possible to manufacture a universal lock for securing the shoulders of various manufacturers.

The developed design of the handle of a sports bow allows for more accurate fitting of the bow and arrow due to two through holes 7 for fixing the plunger above the axis of the stop and above the intersection point of the handle axes.

The proposed technical solution for the design of the handle of a sports bow allows us to ensure compliance with the following requirements for such modern products as:

Minimum handle weight in the analogue segment;

Minimum material fatigue (increased strength);

Minimum deviation of shoulder deformations;

More accurate fit of arrows;

The minimum load on the upper shoulder girdle of the athlete during the execution of the shot.
