Abstract

The invention relates to hand percussion instruments. The purpose of the invention is to increase the reliability of attaching the handle to the working part of the hammer. The connecting element is a U-shaped bracket 1, which is mounted on the working end of the hammer handle. The spikes 2, made on the sides of the bracket 1, perpendicular to them and towards each other, enter the body of the handle. Then the handle with the bracket 1 installed on it is inserted into the mounting hole of the working part up to its abutment bent 180 ° & the end of the sides of the bracket 1. A shock or press load is applied to the part of the bracket 1 projecting above the working part of the hammer, as a result of which the shelf 3 is flattened, blocking the mounting hole. 4 il.

Description

The invention relates to a mass structure, and specifically to hand percussion instruments.

The aim of the invention is to increase the reliability of fastening by preventing the working part from jumping off the hammer handle.

FIG. 1 shows the connecting element, a general view; FIG. 2 is a view A of FIG. 1J in FIG. 3 - assembled hammer; in fig. 4 shows a section BB in FIG. 3

The connecting element of the handle with the working part of the hammer is a U-shaped bracket 1 with spikes 2 on the side surfaces, directed perpendicularly to them and towards FRIEND to a friend, made using the cutting method. Zigzag-like protrusions 4 are made in the place of transition of the shelf 3 to the sides of the bracket, combined with additional zigzag-shaped projections 5 made on the lateral sides and directed inward of the U-shaped bracket. 8 hammer. The sides of the bracket 1 when the handle 9 is connected to the working part 8 of the hammer are placed in planes perpendicular to the end 10 of the working part of the hammer.

The handle is connected to the working part of the hammer as follows.

Bracket 1 is installed on the working end 11 of the handle and compressed on it until it is completely pressed against the side

This means that the spikes 2 enter the body of the handle. Then the working end 11 of the handle with the bracket 1 installed on it is inserted into the mounting hole of the working part 8 of the hammer against the stop into the bent ends 6, 7 of the sides, while the shelf 3 with the projections 4 protrudes above the working part 8 of the hammer. After that, a pressing or impact load is applied to the protruding part of the bracket 1, as a result of which the shelf 3 is flattened, blocking the delivery hole of the working part 8 of the hammer, pressing it to the ends 6, 7 of the bracket 1 and providing a rigid connection of the handle with the working part 8 of the hammer .
