DESCRIPTION

BAR AND DISK SET WITH COUPLING ELEMENTS

OBJECT OF THE INVENTION

The present invention relates to a bar and disc assembly with fasteners for discs intended for sports, such as weightlifting and more particularly exercise equipment of this type that include means for supporting a series of discs at both ends. of a bar, where the coupling elements prevent displacement of the disks outside the bar.

BACKGROUND OF THE INVENTION

In various sports and medical therapies, weight lifting is performed by using discs attached to bars. Said weights are composed of a bar and at least two discs that are located at opposite ends of the bar, forming the set with a balanced distribution of its total weight, suitable for lifting by the athlete.

In the past and present, gyms and health clubs that provide free weights to their customers also provide bar clamps or safety collars to secure weight discs in a bar and / or dumbbell. This would allow the end user or the weightlifter to use the weights without them sliding or moving on the bar during use, which allows the end user to lift the assembly more safely.

For the correct use of the discs with bar it is essential that the coupling between the discs and the bar is carried out in a simple and simple way, that it is firm and with adequate security to prevent the discs from sliding from their position on the bar, which may involve risks of accident or injury to the user in cases where a disc falls on the user when sliding from the bar. In order to carry out said fastening, it is common for conventional bar weights to comprise rings with nuts, clips, etc. configured to fit the bar at its outer ends towards the position of the discs, thus limiting their movement along said bar.

US 4,618,143 (Twardosz) discloses a weightlifting bar that has coupling elements with respect to the longitudinal axis of the bar, so that an athlete can perform lifting exercises for different muscle groups, where the safety of the bar for the displacement and fall of the disks it is carried out by means of concentric rings in the form of a clamp as coupling elements.

US patents US4,566,690 of Schook, and US 5,407,413 of Kupferman, reveal two of the typical dumbbells that include, each of them, one or more weight discs that are secured one at a time. However, a lot of time is spent assembling the weight discs.

Chen's US patent application US 2002/0183174 A1 discloses a dumbbell where the weights can be selectively coupled to the handle by a slide received slidably in said handle and extending through the central hollow of the weights. By sliding the closure further out, it is possible to increase the number of weights coupled to the handle while sliding the closure more therein can reduce the number of weights. This allows the handle user to change its total weight without moving the weights themselves.

The technical problem that serves as a basis for the present invention is to provide a set of discs and bar that allows to adjust the bar and the disc without the need to use couplings at the ends of the bar to hold the discs, avoiding slip and fall. of the disks, so that it is not necessary to make pressure on the junction between the disks and the bar, as well as its sliding, so it provides greater security to the user as well as faster when executing the exercises, since it avoids using other external elements

DESCRIPTION OF THE DRAWINGS

To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, according to a preferred example of the practical embodiment thereof, a set of drawings is attached as an integral part of said description. where, for illustrative and non-limiting purposes, the following has been represented:

Figure 1 shows a view of the exercise bar (1) of the present invention, showing the plurality of rails (4) and the holes (5) above and below the bar (1).

Figure 2.- shows a view of the different discs (2) that can be used with the bar (1), where the keys (4) are shown in each of the discs (2).

DESCRIPTION OF THE INVENTION

The present invention reveals a set formed by a bar (1) and at least one disc (2) for weight or weightlifting exercises, where said set is obtained by attaching the discs (2) to the bar (1) without using other coupling means such as bar clamps or safety collars, the set can be used either for a bar (1) of the conventional type of 28 mm diameter or an Olympic bar (1) of 50 mm diameter, as well as to the discs (2) that are introduced in the bar (1) which can be of different weights.

The bar (1) has two stops (3) at a certain distance from the ends of the bar (1), at each end of the bar a plurality of rails (4) have been made that extend between the ends of the bar ( 1) and the stops (3). Each of said rails (4) has a plurality of holes (5) above and below said rails (4).

The discs (2) each have at least 4 keys (6) that are inserted in the hole (5) of the bar (1), prevent the disks (2) that have been previously inserted at the end of the bar from being released. (1), when placing the load formed by said disks (2).

The assembly allows a comfortable coupling of the discs (2) with the bar (1), in such a way that it is not necessary to apply pressure to fix the discs (2) and the bar (1), as well as prevent their sliding.

By having a greater grip due to the effect of the keys (4) on the discs (2) and the holes (5) on the bar (1), it is not necessary to implement external fasteners in order to prevent the discs from sliding and they leave the bar (1), in such a way that the user, in addition to obtaining greater security, can make the changes of the disks (2) more quickly, since he does not need to decouple external elements that allow to hold the disks (2).
