Description

The invention relates to sports equipment that can be transformed from one type to another, and can be used in the design and manufacture of yangformable equipment for athleticism. dumbbell gymnastics, peak: 1, p.

A combined gymnastic apparatus, comprising a lengthwise integral handle with stops for cargo disks, in the end parts of which there are load disks, and a sleeve covering it having rotation and interaction with stops.

The device can be transformed into a regular dumbbell and allows you to adjust the length of the central part of the handle depending on the width of the hand of the occupant, as well as in a weighted gymnastic stick.

The disadvantages of the device are the complexity of the design and the presence of a large number of parts. In addition, it cannot transform, for example, into a hypothetical one that narrows its functionality.

The closest in technical essence to the present invention is a convertible sports equipment containing two or more dumbbells of variable weight and connecting plates, oval or in the form of sectors of a circle, with holes for dumbbell pins.

A disadvantage of the known device is its limited functionality, due to the fact that the projectile is transformed only in a dumbbell or in a weight.

In addition, the known device is not compact enough when transforming it into a weight, since weight gain is associated with an increase in the length and volume of the projectile and with the use of additional plates and dumbbells.

The fastener design in which a heavy load disk with a pin is screwed into the handle of a dumbbell creates inconvenience when using a projectile.

The aim of the invention is to expand the functionality by providing the transformation of the projectile into a barbell, into a device for training the latissimus dorsi muscles and a weighted gymnastic stick, as well as increasing compactness in packaging and ease of use.

This is achieved by the fact that a convertible sports equipment containing sets of elements for assembling dumbbells, each including a dumbbell bar with a set of weighted discs and clamps for their position on the bar, as well as connecting links in the form of plates with holes on their longitudinal axis, In accordance with this invention, it is equipped with an additional bar of the same diameter as the barbells of the dumbbells and the details of attaching the equilibrium disks on it when assembling all the projectile elements into one unit, while the barbells of the dumbbells have two egg annular protrusions (emphasis) in the middle zone and are made with the possibility of coaxial connection with an additional neck, for example, by carving, the balance discs are made of at least two different diameters, and the connecting links are made with three holes on their longitudinal axis along the diameter of the neck, and the pitch of the holes is not less than half the diameters of the larger disc and neck, and in the general assembly of all elements of the projectile, the discs of smaller diameter are placed in the middle of the additional neck, the larger diameter is symmetrical in its edges, and an additional disc with the neck is secured in the central openings of the connecting links.

The above differences of the invention in comparison with the prototype ensure compliance with the criteria of the invention of novelty.

The causal connection between the distinguishing features of the invention and the effect achieved is that the presence of an additional neck and said execution of connecting links with the possibility of installing weighted discs along the entire length of the additional neck allows the transformation of the apparatus into a weight, barbell, weighted gymnastic stick and device for training the latissimus dorsi.

At the same time, the possibility of installing balance discs along the entire length of the additional neck along with the selected distance between the holes in the connecting links increases the compactness of the shell during packaging.

Since the analysis of other similar solutions did not reveal the popularity of using the distinguishing features of the claimed object to achieve the set goals, we can conclude that the proposal for the application meets the criteria of the invention inventive step.

In FIG. 1 shows an assembled projectile for transportation and, as an embodiment, a projectile transformation for training the latissimus dorsi muscles; on the

FIG. 2 is the same side view, in FIG. 3, the assembly I in FIG. 1, an illustrative embodiment of the structural elements of the latch of the position of the disks on the neck and their location in the assembly of a projectile of this kind; in FIG. 4 - assembly II in Fig. 1, illustrating an embodiment of a structural part for mounting discs on an additional neck during general assembly of elements; in FIG. 5 is a variant of the General view of the connecting link; in Fig. 6 is an embodiment of the transformation of a projectile into a barbell; in FIG. 7 is a variant of the transformation of a projectile in a dumbbell; in FIG. 8 is a variant of the transformation of a projectile into a weight.

The projectile contains (Fig. 1) vultures 1 and 2 for assembling dumbbells (Fig. 7); an additional bar 3 of the same outer diameter with bars 1 and 2, which, when coaxially connected to bars 1 and 2, forms a desired gymnastic stick (not shown) or bar bar (Fig. 6); balancing disks A for transforming a projectile into projectiles of a different kind: connecting links 5 (Fig. 5) for the general assembly of projectile elements and transforming them into some other species, in particular a weight (Fig. 8). in which on the longitudinal axis there are three holes b in the diameter of the neck in increments of not less than half the diameters of the larger of the weighted discs 4 and the neck. In one of the mountaineers, the vultures 1 and 2 have a threaded socket 7, and the additional neck 3 at both ends has a shank 8 with the same thread mating to the socket 7 to provide coaxial connection of the vultures into a weighted gymnastic bar or barbell. Vultures 1 and 2 have two symmetrical annular protrusions 9, which serve as stops for the equilibrium disks 4 when transforming a projectile into a dumbbell or bar and for connecting links 5 when transforming a projectile into a weight (Fig. 8). The balancing discs 4 are fixed at the ends of the vultures 1 and 2 or neck 3 during transformation of the projectile into other types, as well as the spacing of the connecting links 5 during the general assembly of the projectile is carried out by lock washers Jus with fixing screws 11 (Fig. 3). In order to secure all balance discs 4 and connecting links 5 to the neck 3, for the general assembly of the projectile, shaped nuts 12 are provided that are screwed onto the shanks of the neck 3 (Fig. 4).

For individual lessons and trainings, two dumbbells are enough, therefore, in the general set of projectile elements, there are two barbells for assembling dumbbells, and the number of weighted disks for adjusting the load and the sporter of heavier shells - rods, weights is increased. In the embodiment shown in the drawings Yes, balancing disks of two different diameters are provided, which allows a common

the assembly of all elements of the projectile should be used as a projectile for training the latissimus dorsi muscles if disks of smaller diameter are placed in the middle of the additional neck 3 (Fig. 1). With different

the diameters of the disks 4 are of the order of 50 mm and the indicated pitch of the holes b in the connecting links x 5 in the assembly of FIG. 1 projectile between the central part of the vultures 1 and 2 and discs 4 of smaller diameter is formed

a gap of at least 25 mm, which is sufficient for the fingers to pass the absolute largest number of projectile users.

The distance between the stops made on the peripheral parts of the composite neck for balanced suits. corresponds to the width of the palm of a person and is selected equal to 135 mm, which is suitable for the vast majority of projectile users

From the point of view of compactness in packaging and ease of use of the projectile, it is most expedient to make an additional neck of the same diameter and length with dumbbell bars.

Transformable sports equipment in accordance with this invention with the same external dimensions compared to similar known can have a significantly larger - approximately

35% weight. It has wider functionality, more convenient to operate and quite simple to manufacture.

The usability of the projectile also consists in the fact that when transforming it into a projectile for training, for example, the latissimus dorsi muscles, a variable number of unbalanced disks can be worn on the middle area of the central part of the neck.

Fixing them along the length of the neck is ensured by the fact that between the stops of the peripheral parts of the vultures and dumbbells, locking washers are installed by connecting links that can be displaced and fixed

in the right position.

In addition, the peripheral parts of the neck. employees-handles have the ability to rotate around its axis, which eliminates the friction of the palm occupied by the handle and thereby increases the comfort of using the projectile.
