TRAINING TOOL

DESCRIPTION OF THE INVENTION

Field of invention

The present invention falls within the sector of gymnastic equipment, and in particular concerns a training tool.

State of the art

In the gymnastics and sports field? known the use of a training tool comprising a weight having one or more? layers of external covering in semi-rigid material, for example in rubbery and/or vinyl polymers, and having a cavity? internal that houses a quantity? of fluid and/or solid material, for example water, sand or metal marbles, such as to give the weight a certain mass. Weight ? intended to be grabbed, lifted, moved, thrown or used in various activities? gymnastics by one or more? users, while carrying out specific physical exercises aimed at improving muscle strength, agility and reflexes.

The weight can be equipped with handles welded to it or removably fixed, such as to allow a user more firm grip on the weight itself. Furthermore, training tools including weights and other tools for carrying out physical exercises are known. For example, ? I notice a balance wheel to which at each end? ? fixed a weight, intended to be used in weight lifting and handling exercises.

The main disadvantage of known tools consists in the fact that the weight must be kept lifted from the ground while carrying out the various exercises, thus involving a considerable and additional effort on the part of the user.

Another disadvantage of the known tools? that the physical movements that can be performed by the user while using the weight are limited due to the mass of the weight and the need for to keep the latter raised from the ground.

Summary of the invention

The main purpose of the present invention is? that of proposing a training tool comprising a weight that remains independently lifted from the ground during use.

Further purpose? is to propose a tool that allows the user to perform a great variety? of physical movements and training in a large number of different exercises.

Detailed description of the invention

With reference to figures 1 to 14, 1 indicates a training tool comprising:

- a weight of 2;

- a connection means 3 connected to the weight 2;

- a means of suspension 4 of weight 2, fixed at one end? to the connection means 3 and to another end? to a support element 100;

- a gripping means 5 which interacts with the weight 2 for its movement by a user in correspondence with a condition of use U of the tool 1.

The support element 100 ? for example a ceiling or a fixed beam above weight 2; therefore the suspension means 4 keeps the weight 2 suspended and free to oscillate in the condition of use U.

The user can train by pushing and braking the weight 2 using the grip 5.

The weight 2? preferably composed of an external shell 6 of an almost spherical, of variable size similar to that of usual sports balls or medicine balls, made of rigid or semi-rigid material, for example metallic or polymeric, and of variable thickness.

The external shell 6 forms an internal volume 7 which houses a predetermined mass 8 of fluid and/or solid material, for example water, sand or metal marbles.

The mass 8 ? left free in the internal volume 7, so that? during the movement of weight 2 the center of mass of the latter changes, making the movements of the weight itself unpredictable for the user.

In a variant not illustrated, the weight 2? a sphere full of density? almost? uniform.

One or more? openings 9, preferably two, obtained through the external shell 6 put the internal volume 7 in flow communication with the outside of the weight 2, allowing the quantity to be modified. and the type of mass 8.

Each opening 9 ? closed by a respective closing means 9?, which is for example a cap fixed to the respective opening by screwing or interference. The means of connection 3 ? preferably metallic, for example steel, in order to offer greater robustness to the stresses suffered by the weight 2 during use U, and has a loop 71 externally protruding or enclosed within the external surface of the weight 2 to which the means of suspension 4.

The means of connection 3 ? preferably welded to the outer shell 6 of the weight 2, or alternatively ? welded to one of the closing means 9? and therefore through the latter? fixed to weight 2 in correspondence with an opening 9.

In the preferred embodiment, the suspension means 4? a flexible cable, preferably a rope or ribbon of synthetic material and of adjustable length, or rigid, for example a metal rod, or an elastic band, or a spring, or similar. String 4? knotted directly to the loop 71 of the connection means 3 or is there? secured in an equivalent way, for example via a carabiner.

The period of oscillation and the trajectory of the center of mass of the weight 2 are essentially determined by the thrust provided to the latter by the user and by the length of the suspension means 4.

By adjusting the length of the suspension means 4 and the quantity? of mass 8 ? is it possible to vary the entity? of the effort and type of physical movement required of the user to push and brake the weight 2.

The gripping means 5 through which the user moves the weight 2 preferably comprises a blade 10 with an almost by spoon.

The blade 10 has a?end? distal 13, one?extremity? proximal 14 opposite the extremity distal 13, a convex rear surface 11b and a front surface 11a defining a cavity 15 almost? complementary to at least a portion of the weight 2 and intended to partially accommodate the weight 2 for its movement during the use U of the tool 1. The shovel 10 has a shape such that its frontal projection is almost? ?pear-shaped?, being more wide at two opposite lateral portions 12 and more? narrow at the ends? distal 13 and proximal 14, with the segment connecting the latter almost? orthogonal to the connecting segment between the lateral portions 12.

The extremity distal 13 ? what? defined why? ? intended to remain in a distal position with respect to the user in the U condition of use. proximal 14, on the contrary, has an attachment 14? on the rear surface 11b through which the user can? maneuver the shovel 10, directly or with the aid of a grip means fixed to this attachment 14?.

The extremity proximal 14 of the blade 10 extends frontally for a better and more enveloping grip on the weight 2.

The radius of curvature of the cavity? 15 ? similar to the radius of the weight 2 at the end? proximal 14 and increases progressively in proximity? of the extremity distal 13. The cavity? 15 turns out like this? at least partially complementary to a portion of the weight 2. The particular shape of the cavity? 15 ? such that, in correspondence with the condition of use U, the extremity? proximal 14 provides a grip on the weight 2 to brake its oscillation and move it, while the softening of the curvature of the cavity 15 in a distal direction towards the extremity distal 13 allows you to accelerate the weight 2 to throw it. Shovel 10? made of rigid and light material, for example aluminum or plastic or based on carbon fibre. To increase the strength of the blade 10, this is? equipped with a reinforcing pin 72, such as for example a protruding rib, which connects the midpoints of the ends? distal 13 and proximal 14 along the posterior surface 11b. Secondary branches, not shown, can originate from this rib 72 for a further reinforcing effect.

Almost? in the middle of the reinforcing pin 72 on the rear surface 11b, the blade 10 has an eyelet coupling means 16 to which to attach, in correspondence with the condition of use U, a resistance element 17 intended to increase the effort required of the user to the interaction with the weight 2 via the blade 10.

The resistance element 17 ? an elastic element, such as for example an elastic cord or a spring, having a first end? tied to the attachment means 16, directly or via a carabiner, and a second end? bound to a locking element 101 which is fixed with respect to the support element 100.

The locking element 101 is for example a wall or a floor.

In figure 3? illustrated is a variant of the tool 1 in which the resistance element 17 is consisting of a further weight 2 tied to the attachment means 16 of the blade 10 via an anchoring means 18, which is for example a rope, or a cable, or a chain, or similar. This weight 2 ? free to oscillate during the movements of the blade 10, making it possible for the user to carry out more difficult exercises.

The shovel 10 also features? two slots 19, each obtained in a respective lateral portion 12, intended for blocking a means 20 for fixing a load 21 to the blade itself in a further variant of the tool 1.

Load 21? preferably a ball of similar size to that of weight 2 and of variable mass.

The fastening means 20 ? for example a double ring tape, with a first ring that presses on a first meridian of the load 21 keeping the latter in contact with the front surface 11a of the blade 10, passes through the slots 19 and closes with a tear on the rear surface 11b, and with a second ring that wraps a second load meridian 21 orthogonal to the first. The two rings are mutually locked at their two intersections.

In the preferred embodiment, the gripping means 5 includes a rod 30 at each of whose ends? ? fixed a blade 10, in correspondence with the attack 14? of the respective extremity? proximal 14.

Auction 30? rigid, for example made of aluminium, with a tubular profile, and? intended to be held by the user with both hands. The auction 30 can? be made in a single body, or can it? be divided into two parts to be joined, for example by mutual screwing, at a median junction 31 of the rod 30 before the condition of use U. The length of the rod 30 is variable from 30 cm to 300 cm depending on the height of the user and the type of exercise that the latter wishes to perform. In a variant of the preferred embodiment, the gripping means 5? consisting of a shovel 10 fixed to a handle 40 in correspondence with the attachment 14? of the extremity proximal 14.

The handle 40 has two rigid tubular prongs 41 welded at a respective end. to which ? fixed the blade 10 and arranged so that the angle between them is between 5? and 150?, preferably 40?. The prongs have a length between 20 cm and 100 cm, preferably 40 cm.

A further variant of the preferred embodiment provides that the gripping means 5 is constituted by a blade 10 fixed to a tubular hilt, with a length between 20 cm and 100 cm, in correspondence with the attachment 14?. The hilt? intended to be held by the user with one or both hands, allowing the user to carry out a great variety of tasks. of exercises and movements particularly suitable for specific sports.

A second embodiment of the tool 1 provides that the gripping means 5 consists of two handles 50. These handles 50 are obtained in diametrically opposite positions on a first band 51 of textile tape closed by tearing along a meridian of weight 2 which intersects the means of connection 3. The first band 51 ? fixed to a second band 52 of tape closed around the weight 2 along the equator.

Another embodiment of the tool 1 provides that the gripping means 5 is a sheet 60 made of flexible material, for example textile or plastic. The sheet 60 includes a central rectangular portion 61, preferably 30 cm high or in any case similar to the diameter of the weight 2, and preferably 50 cm wide or in any case slightly greater than the height.

At each of the ends? sides of the central portion 61 ? created a tubular pocket 62. In correspondence with the condition of use U, the user inserts a hand and/or a forearm into each pocket 62 to stretch the central portion 61, thus to be able to dampen and reject the oscillating weight 2.

A further embodiment of the tool 1 provides that the weight 2 has a multilobed shape, preferably with two lobes, with each lobe 2? in shape almost? spherical and partially mutually interpenetrating with the other lobe. The means of connection 3 ? fixed along the circumference defined by the intersection between the two lobes 2?.

Optionally, the tool 1 also includes one or more? sensor means 80 intended for monitoring training and fixed to the weight 2, for example at or inside the closing means 9?, and/or to the connection means 3, and/or to the suspension means 4, and/ or to the gripping means 5, for example to the shovel 10 or to the rod 30.

The sensor means 80 comprise electronic sensors of the inertial type, for example accelerometers or gyroscopes. Each sensor means 80 measures with a predetermined frequency the temporal trend of the three-dimensional acceleration of the element to which it is connected. fixed, producing a sequence of digital data; knowing the mass of weight 2, ? It is possible to obtain the trend of the force imparted by the user to the weight 2 itself during its use U through the well-known formula force = mass x acceleration. The use of these sensor means 80 therefore allows to monitor training parameters such as energy consumed by the user, number and type of movements performed, duration of the concentric and eccentric phases of the user's muscle contractions, entity? of the force imparted to the weight 2, and similar.

The data produced by each sensor means 80 are saved on a respective electronic memory and then extracted and processed at the end of the training, or alternatively they can be transmitted by radio frequency in real time from the sensor means 80 itself to a central processor for real-time monitoring reality of training.
