Description

DESCRIPTION

Safety accessory for sports equipment

TECHNICAL SECTOR

The present application refers to a safety accessory that can be used in weight benches or similar sports equipment, in which a user lifts a high weight that, in the event of a problem, may fall on his body or another delicate place.

It is applicable in the sports industry.

STATE OF THE ART

The use of weight benches and other equipment or apparatus in which a user lifts or pushes a high weight, exercising and developing their muscles is known. In these devices you can perform different types of exercises for physical improvement, either by forcing the load, forcing the number of repetitions ...

These devices have a high risk of accident, especially weight benches, when the user cannot adequately support the weight due to having exceeded its resistance. In the case of weight benches, it is common to place a support person to remove the weight in the event of an accident, reducing the risk of injury to the user.

However, this implies the need for support people and that they are extremely attentive, since if the weight is high, it is possible to cause an injury almost immediately.

The applicant does not know of any system that allows solving all these problems as easily as the invention.

BRIEF EXPLANATION OF THE INVENTION

The invention consists of a safety accessory for sports equipment according to the first claim. Its different variants solve the problems outlined.

This safety accessory is designed for the type of sports equipment that comprises one or more weights. It consists of a lifting mechanism that can be connected to the weights and configured to allow relative upward movement between the weights and the lifting mechanism from a rest position (when the user does not make any effort), and at least one activation control of the lifting mechanism at the discretion of the user or a support person. The lifting mechanism can be connected to the weights, so that part of it always rises with the weights, or be totally immobile until the activation control is actuated. In this second case, the upper part will be wide and resistant to ensure that the weights are always picked up by the lifting mechanism.

In one embodiment, the lifting mechanism is one or more hydraulic or pneumatic cylinders, connected to a motor. In this case, the connection between each cylinder and the weights is made by a piston movable in a sleeve, one element (piston or sleeve) being fixed to the cylinder and the other to the weight.

In another embodiment, the lifting mechanism is connected to the weights by a strap or the like. In this case, the cylinders, a motorized pulley or other mechanism can be used to pull or retract the belt or the like and lift the weights.

Other variants can be seen in the rest of the report.

MODES OF EMBODIMENT OF THE INVENTION

An embodiment of the invention will be briefly described below, as an illustrative and non-limiting example thereof.

Figures 1 and 2 show two schematic examples of embodiment, applied to a bench (1) of weights (2). The weights (2) are fixed in a stable way to respective accessory examples, in this case formed by hydraulic or pneumatic cylinders (31) connected to a motor (32), which in turn is controlled by a control (33).

The accessory is, in its most general form, formed by a lifting mechanism (31,42) connected to the weights (2) and one or more controls (33). The connection between the weights (2) and the lifting mechanism (31) allows relative upward movement between the weights (2) and the lifting mechanism (31,42), but not vice versa. The lifting mechanism (31,42) can be fixed to the weight bench (1), to move with it.

The cylinders (31) of the are uncoupled from the weights (2) in normal operation (figure 1, right). This implies that the weight (2) has freedom of movement with respect to the cylinders (31). When the user or a support person presses the knob (33), the cylinders (31) extend (figure 1, left) and take the weights (2) freeing the user.

In figure 2, the weights (2) are fixed to the rod of a plunger (34), whose sleeve (35) is the upper part of the cylinders (31) (figure 3). Thus, the user can lift the weights (2) by moving the plunger (34) upwards. However, you cannot remove the weights (2) from the cylinders (31) accidentally. If the user needs to lift the weights (2) quickly or ensure that they do not descend, he activates the control (33) that extends the cylinders (31), so that it is the sleeve (35) that moves upwards, pushing or reaching the position of the plunger (34). The sleeve (35) can have valves that facilitate the entry and exit of air from each chamber, which if calibrated allow the weight (2) to be lowered slower than the rise, reducing the risk of accidents. For this, non-return valves are provided with different air inlet and outlet gauges of the corresponding chamber.

In a second embodiment (figure 3), the weights (2) are hung from one or more straps (41), cables, slings or the like of sufficient strength. Each belt (41) can be stretched by a cylinder (31) or by a motorized pulley (42). If desired, a pulley, winch ... can be placed to bypass the belt (41) or the like and place the cylinders (31) or the motorized pulley (42) on the ground or side instead of in an elevated position. When the user lifts the weight (2), the flexibility of the strap (41) or the like allows the accessory not to affect their movements. The motorized pulley (42) will preferably be removable to locate at any other point if the weight bench is moved from its initial position. It may also comprise a movable pulley or winch, for example on guides, the motorized pulley (42) always keeping at the same point.

The control (33) can be accessible to the user, so that he does not need a support person. It can also be accessible to that outside person, or to both. For example, it can be a pedal.

Ideally, the control (33) activates the cylinders (31) and leaves them activated until a predetermined time elapses, or while it is not supported on a second, less accessible button to avoid accidental pressure. East The second button relaxes the cylinders (31), so the weights (2) can return to normal use.
