Abstract

The invention relates to projectiles and devices for performing physical exercises and allows for improved usability. The dumbbell consists of two hollow parts 1 and 2, and the cavity is made the same in shape, but different in size. The presence of cavities involves the placement of two liners 9 and 10 in them. Inserts can be used both in pairs with each other or separately. When the liners are installed separately, support areas “b,” g, “d of the surface of part 2 appear, which serve as the supporting plane for the liner that is installed in them. This is achieved by making the end parts of one of the inserts 9 asymmetrical relative to one another and the corresponding parts of the insert of another part of the dumbbell. 2 hp f-ly, 8 silt, 2 tab.

Description

This invention relates to physical exercise tricks, in particular, dumbbells.

The purpose of the invention is to improve ease of use.

FIG. 1 shows a dumbbell, front view; in fig. 2 - section A-A of FIG. one; in fig. 3 and 4 are the same as the second embodiment; in fig. 5 and 6 - the same, the third embodiment; in fig. 7 is a section BB in FIG. 1, 3 and 5; in fig. 8 is a section bb of FIG. 1, 3 and 5.

The dumbbell consists of parts 1 and 2 that are detachable along the longitudinal plane. Each part consists of cases 3-6, respectively, and a handle 7 and 8 connecting them. Each case and handle have cavities that form one common cavity for accommodating an insert 9 and 10. Moreover, the common cavity of one part of the dumbbell, although it is made symmetrical to itself, but differs from the common cavity of the other part 2, which is designed in such a way that its end sections are asymmetric one another and the corresponding sections of the first part of the dumbbell. The cavity of the housing 5 is wider and shorter than the cavity of the housing 6. In both common cavities can be installed inlays 9 and 10, having the shape of the cavities in which they are inserted. Their fixation is carried out due to the contact of their middle parts. When drawing up a combination of two parts with one insert 9, its fixation can be accomplished by rotating the insert through 180 ° and resting it on the surface areas of the counterpart, which arise due to the difference in dimensions along the width and length of the cavities of buildings 5 and 6 and end parts And and 12 liners 9. A wider portion 11 of the liner cannot be lowered into the cavity 13, the size of which is smaller than its width, and rests on a part of the body of the body 6. The second part 12 of the liner is also similarly located, having a smaller width but greater length than cavity l 14 housing 5.

In the first embodiment, the length of the inserts 9 and 10 of both parts is different. In the second embodiment (Fig. 3 and 4), their length is the same, but the implementation of the end parts of the insert 9 is similar to the performance of their first embodiment. In the third embodiment (Figs. 5 and 6), the cavity and the insert 9 are displaced in the longitudinal direction relative to the cavity of the first part of the dumbbell so that the lengths of the parts of the cavity “a,” in are not identical with respect to the transverse plane of symmetry 00 of the dumbbell.

The use of dumbbell variants is based on the compilation of various combinations of weights from its constituent elements: parts 1 and 2 and inserts 9 and 10.

In the case of simultaneous use of all four elements of the dumbbell fixation

The liners in the respective parts 1 and 2 are made by contacting their middle parts.

When making a combination of two

parts 1 and 2 with one insert 10, the insert is fixed in part 1 in order to prevent it from falling from one part to another in all three ways by resting its end parts on the connector surface of part 1. Such an opportunity of fixing the insert is due to that the end portions 13 and 14 of the cavity of part 2 are made smaller in relation to the corresponding end portions of the cavity of part 1 (Figs. 1, 3, 5 and 7).

5 As a result, in the plane of the connector, sections "B" are formed on the housings 5 and 6, on which the liner 10 can rest (Fig. 2, 4 and 6, the contours of the cavities of parts 1 and 2 in the plane of the connector are indicated by a dash-dotted line).

0 When making a combination of two parts 1 and 2 with an inlay 9, it must be removed from the cavity of part 2, rotated 180 ° around the horizontal longitudinal axis and placed in the cavity of the housing 1

5 (Fig. 2, 4 and 6; Fig. 1, 3 and 5, the position of the insert 9 is indicated by a three-dotted line). When combining parts 1 and 2, the liner 9 rests on the supporting portions "g and" g, which appear on the part of the connector 2

0 on either side of the longitudinal axis.

In the first and second embodiments, the support portions "r and" d arise due to the asymmetrical performance of the end portions of the cavity (and hence the liner 9) of the dumbbell part 2. In the third variant, these sections are formed by shifting the cavities of parts 1 and 2 along the longitudinal axis, with the result that when placing the insert 9 and part 1, it shifts relative to the cavity of part 2 and rests on the formed

0 while in the plane of the connector on the part 2 of the supporting sections of the “g and“ D.

The longitudinal movement of the insert 9 in part 1 with the specified set of elements in the first and third embodiments is prevented by contact of its middle part with the middle part of the body (manual) part 1 provided that the manual parts of the insert 9 and part 1 are equal.

In the second embodiment (Figs. 3 and 4), the longitudinal movement of the insert 9 per hour Qi I is prevented by contacting the end parts 15 of the insert 9 with the body of bodies 4 and 5 along the surface 16.

After assembling the dumbbell with the required load, the occupying hand grabs the dumbbell in its middle part and

5 most fixes all its elements. Individual elements of the dumbbell can be used when several people simultaneously occupy, for example, in the family of a father and son.

Example. Arrange the weights of the dumbbell elements according to the geometric row with the denominator 2. Then, with the weight of the insert 9 of 0.75 kgf, the weight of the insert 10 will be 1.5 kgf, parts 1-3 kgf, parts 2-6 kgf.

The range of loads on each arm at the same time, obtained with various combinations of the weights of the indicated elements (1-15) and onto one hand while recruiting one of the two dumbbells (16-18) is presented in the table.
