Description

DESCRIPTION

Folding multifunctional training equipment

technical field

It is an object of the present invention to provide a solution to athletes, whether professionals or amateurs, who live in the city or in apartments of a few square meters and want to have a bodybuilding equipment at home, offering them a more complete and configured bodybuilding equipment. to take up as little space as possible.

State of the art

In the current state of the art there are different bodybuilding equipment for home use, but they are not designed for use in small spaces, and those that are, do not meet the minimum requirements for progressive muscle development, missing important elements, such as the lack of more weights to increase the load, or specific exercises important for the muscular development of the lower body, such as a 45° press, quadriceps extensions and lying leg curls. Therefore, to train the lower body at home, for a bodybuilder, the current domestic machines are insufficient, limiting their training to private gyms.

More specifically, the following exercises are important for working the lower body, and currently, it is not possible to do them with a home-use machine.

Thus, for example, the 45° leg press is an essential element for any gym, since it involves practically all the leg muscles, focusing more on the quadriceps and calves, which is why a high volume of exercise is needed. load (i.e. more weight to lift). The main drawbacks for which these presses are not used in domestic use are:

- In the case of home multifunctional equipment, press tools or accessories that are reliable and sufficiently loaded for professional training (which requires large weight loads) are not included.

- The cost and volume occupied by an independent equipment for leg press is high (a minimum cost of 1,000 EUR) and measures approximately 200 cm 250 cm long, 140 cm - 150 cm high; and 70 cm - 190 cm wide, which makes it unfeasible in many homes.

- It is necessary to have many weight plates stored (between 400 kg and 600 kg maximum load for professional equipment). It is true that there are leg press equipment with a tower of guided weights, where it is not necessary to load with the discs, but they tend to increase their price and reduce their maximum load, since it is a system that works by stretching the weights through a cable steel and pulleys.

Another essential leg exercise is leg extensions, since it allows you to work the quadriceps, which is the most powerful and voluminous muscle of the leg, occupying almost a third of its volume. The drawbacks to home training are:

- The multifunctional home equipment lacks the load (weight) sufficient for a professional training of the quadriceps.

- They are uncomfortable, as the seat of the backrest is not adjusted and the measurements are (often) insufficient to work comfortably.

- The cost and volume of professional equipment for leg extensions is also too high to have one at home exclusively for this exercise.

In the lying leg curl, the femoral muscle of the legs is trained, which are the muscles of the back of the legs, also called hamstrings. The problems for which the leg femoral training cannot be performed lying down are:

- In the multifunctional equipment that exists on the market, the leg curl is usually worked standing up, using the leg extension tool, but it is more uncomfortable and complicated to work on.

- There are benches for leg curls and leg extensions to which weight plates are added as a load, but there is the same inconvenience, that is, little weight for the extensions, many plates to store, impractical and uncomfortable, being weight plates insufficient measures.

- Again, as with the rest of the exercises described above, having professional equipment to train the leg femoral muscle lying down is expensive and takes up too much volume for a single exercise.

The power rack or cage is a tool that allows you to perform a variety of strength and power exercises, allowing you to lift very heavy loads safely. It is a great help, both to develop the muscles and to simply tone up. The drawbacks of these machines for use in a home environment are:

- The main problem is the volume it occupies, unfeasible for most homes. To avoid this problem, collapsible power cages are known. However, these devices lack the structure to expand with more accessories and remain foldable, so their volume also increases with each accessory added to the equipment. In addition, folding systems do not allow you to conveniently train all muscle groups, so they are limited only to the specific exercises that each accessory allows, in addition to those of the folding equipment, such as the pull-up bar and exercises with a bar used as a support. this structure.

- These types of machines are usually used to do pull-ups and squats, among other exercises, as well as to support a bar (which can optionally be Olympic), with weight discs for different exercises. Its use is limited to those exercises only, unless the equipment is complemented with other tools or accessories such as rings, climbing ropes, bars to do dips for triceps, a bench to do push-ups, a pulley system with weight plates. guided for load exercises, among others. In this case, the problem is that you increase its volume more and more with each accessory, while the product becomes more expensive. Many weight plates are also stocked, as there are a variety of exercises that require using this type of load.

In short, the existing bodybuilding equipment on the market for the general training of the entire musculature (multifunctional equipment) is not effective or sufficient for the bodybuilding work of the lower body. To solve these deficiencies, a strong economic investment is currently required, with the use of independent equipment that occupies a large volume, which prevents its use in domestic environments, particularly in private homes in large cities.

Therefore, a unique piece of equipment is necessary that allows a complete training and with sufficient load of the lower body, so that it can be used by bodybuilders and/or athletes. professionals in a domestic environment, for which it is necessary that it occupies as little space as possible.

Explanation of the invention

The object of the present invention is to provide a foldable multifunctional training equipment that allows to reduce the volume occupied by a multifunctional bodybuilding equipment, at the same time that it is supplemented with a foldable equipment and configured to perform the most used exercises in train training. lower, increasing the load with the weights corresponding to this type of exercise. It is another object of the invention that the folding multifunctional training equipment can be closed in a drawer or cabinet, in such a way that it is stored as if it were any piece of furniture. These objects are achieved with the equipment of claim 1. Particular and/or preferred solutions of the invention are described in the dependent claims.

More specifically, the equipment of the invention comprises a folding power cage, configured to add a system of pulleys and guided weight towers as a load, designed for folding the entire assembly in the smallest possible space, to which is added a removable tool for a guided bar and a second folding set for leg training comprising: a bench and a seat with adjustable position; a 45° leg press; a piece of equipment set up to train quadriceps extensions; and equipment set up to train the lying leg curl.

Thanks to the equipment of the invention, a multifunctional training equipment is obtained that is different from that described in the state of the art, more complete and in less space. It is, therefore, a more versatile piece of equipment, since it allows all muscle groups to be exercised in small spaces, facilitating access to those athletes who, because they live in cities or in small homes, do not have enough space for a complete gym. In the home.

Detailed explanation of an embodiment of the invention

The training equipment according to the present invention is shown in Figure 1. This figure identifies the main parts, technical means or assemblies that make up the equipment of the invention. The training team comprises, at least:

a collapsible power cage (100);

lower body training means (200) that are foldable and transformable for performing the leg press exercise at 45° (figure 6), leg extensions (figure 7) and/or lying femoral curl (figure 8);

means for positioning a guided bar (300);

at least two parallel guided weight towers (400); Y

power transmission means (500) made up of a plurality of pulleys and steel cables -preferably- and which are configured to enable the folding of the training equipment and which, in turn, comprises at least:

two height-adjustable pulleys (501,502); Y

two bottom center pulleys (503, 504);

in such a way that the folding power cage (100) is configured as the main structure of the lower body training means (200), as well as the means to position a guided bar (300), using the weights arranged in the parallel towers of guided weights (400) to configure the load of each exercise; and where, in addition, the lower body training means (200) and the guided bar (300) are connected by means of power transmission means (500) to the guided weight towers (400).

Thanks to this structure, the different parts that make up the whole of the training equipment of the invention do not interfere with each other, also facilitating the performance of the different training exercises. Likewise, said training means (200) and the guided bar (300) can be used independently.

Figure 2 shows an isolated view of the main structure of the training equipment, that is to say, the folding power cage (100), whose main characteristic that the structure of the cage must have is that its folding must not interfere with the other elements that the machine incorporates, that is, the means of training the lower train ( 200), the means for positioning the guided bar (300); the guided weight towers (400) and the power transmission means (500). For this, the structure of the collapsible power cage (100), in turn, comprises:

a first arm (101) and a second arm (102) located respectively to the left and right, formed by bars with an "L"-shaped profile, said arms (101,102) being foldable by means of a plurality of hinges (103) provided with some blocking means (as shown in detail in Figure 3), and the arms (101,102) also being configured to support the means for positioning the guided bar (300) and the power transmission means (500) , for which said arms are provided with an iron or square, chromed or stainless steel profile with holes that will allow the height of said means to be placed; Y

a first central spar (104) and a second central spar (105) that are a "U" shaped profile configured to fix and/or anchor the training means of the lower body (200), as well as guides for the wheels in the deployment of the means of the lower train (200).

Figure 3 shows in detail the locking system of the hinges (103) that facilitate the folding of the power cage (100). The arms (101,102), in addition to their "L" profile, are designed with a superior clearance and some blocking projections (106) configured to block the opening and closing movement of the arms (101,102) of the cage (100) in different angles.

Thanks to this arrangement, the arms (101, 102) can open more or less depending on the exercise that you want to practice at that moment. In fact, to open or close the arms (101,102) it would only be necessary to lift said arms (101,102), while they are folded or unfolded, to later let them fall downwards so that they fit into the locking projections (106) and remain held in position. Finally, with a tightening nut or pin (a retainer, 107) the locking position at the chosen angle of the power cage (100) is ensured.

The lower body training means (200) are shown in figure 4.

The lower body training means (200) is configured as a seat or bench folding (figure 5) with which you can do three of the most important exercises to work the leg muscles, make the bench unfold into three different teams occupying the least space possible and be able to load it with weight with the towers (400 ).

In addition, to work the lower body, robust and strong equipment is needed, which can withstand a lot of weight, so its integration is not obvious in a single folding equipment. More specifically, the lower body training means (200) comprise at least:

some guides (201), preferably two, in the shape of a «U», with drop-down legs and with wheels and/or bearings, where the guides (201) are configured as the support structure of the lower body training means ( 200);

a guided carriage (202) and mobile between the guides (201) thanks to a plurality of wheels and/or bearings;

a base (203) for press, collapsible and foldable, where said base (203) is configured as a seat on one of its faces and is divisible into two parts to perform the lying leg curl exercise (better described in figure 8);

a seat backrest (204) removable and adjustable in inclination;

a first tool (205) configured to train the quadriceps and femoral muscles, this first tool (205) being independent of the structure of the lower body training means (200) and positionable depending on the exercise to be performed; Y

a second tool (206) independent and fixable on the guided carriage (202) and is configured to increase the load of the press when performing the leg press exercise at 45° (see detail in figure 6) with external weight discs .

The structure of the bench and the adjustable seat are shown in figure 5.

The first function that is available only by deploying the training means of the lower body (200) in its use as a bench and/or adjustable seat, since without deploying any other element, a bench with a padded upholstery is obtained to perform several different types of exercises such as, for example, and not limited to, the lying bench press, the seated shoulder press, among others, for which there is a rod (207) configured to support the backrest (204) at the proper angle to the seat (203).

Figure 6 shows the setup for performing the 45° leg press exercise.

To carry out this exercise, the lower face of the base (203) configured as a seat and the removable backrest (204) is placed in its corresponding anchorage, with which the typical structure of a 45° leg press is configured. Its weight load would be regulated by the towers (400) whose power would be transmitted through the power transmission means (500) and, specifically, through the two lower central pulleys (503,504) and their corresponding transmission cables. Likewise, during the configuration of the structure we have the option of blocking the guided carriage (202) using retention bars or supports that are activated by means of levers located on the sides of the «U»-shaped guides (201).

Optionally, it is possible to place the second tool (206) to add additional weights or loads and further increase the load if necessary. Thanks to the two guided weight towers (400), however, the number of additional weights or loads will always be much lower than what would be needed with an independent and specific machine for performing this exercise.

Figure 7 shows the configuration to perform the leg extension exercise.

In this case, the reclining or adjustable seat shown in the configuration of Figure 5 will be used with the lower body support structure (201) in its horizontal position, unfolding some legs, to which only the first tool (205) will be incorporated. ) configured to train the quadriceps and the femoral, in such a way that it is possible to lift the load configured in the guided weight towers (400) by means of the power transmission means (500) and, specifically, by means of the two lower central pulleys ( 503,504) and their corresponding transmission cables.

Figure 8 shows the setup for performing the lying leg curl exercise.

As for training the quadriceps, the first tool (205) configured for the femoral curl exercise is also used, completely laying down the bench for its practice. The load is configured in the guided weight towers (400) by means of the power transmission means (500) and, specifically, by means of the two lower central pulleys (503,504) and their corresponding transmission cables. The peculiarity of this exercise, as shown in figure 8, is that the base (203) can be divided into two parts and raised by its joining area, so that the user can give the bench the necessary inclination and that It is typical of this type of equipment, for the best use of the load and comfort of the user.

Figure 9 shows the positioning means of a guided bar (300).

In the state of the art, guided bar equipment has the bar fixed and attached to two bearing guides on each side. This structure is a problem, since with a fixed crossbar it would be impossible to fold the equipment, so it would have to be dispensed with, which is not desirable.

Therefore, to provide the equipment with a guided bar without losing the folding capacity of the equipment as a whole, it has been necessary to design an accessory (the positioning means (300), located on the arms (101,102) of the cage (100) ) that allows placing and removing the guided bar, in such a way that it is possible to fold the equipment and, in addition, to be able to use the loose bar for other exercises, either as an Olympic bar or a non-Olympic straight bar. The positioning means of a guided bar (300) comprise:

a clamp (301) with bearings configured for different profile measurements; and a latch (302) configured to catch or anchor the guided bar.

Figure 10 shows the power transmission means (500).

The power transmission means (500) are made up of a plurality of pulleys (501 to 505) and cables, preferably made of steel, which allow the structure of the equipment, that is, the power cage (100), to be folded. For this, it has been necessary to solve the following technical problems:

a) The steel cables do not allow the equipment structure to be folded and unfolded. When performing the folding and unfolding movements, the cables tighten and loosen, coming out of the guides and pulleys, not allowing the structure to close.

b) Being a small piece of equipment, there is little space available to place the pulleys and the stretching points (the points through which the power of the exercise is transmitted to the weights) without hindering or interfering with the other elements of the equipment. set.

To solve these drawbacks, the power transmission means (500) have been designed in such a way that the transmission cables pass through a conduit (506) located in the opening axis of the arms (101,102) of the power cage. (100) adding a double pulley (505), so that the combination between the duct and the double pulley allows the folding of the arms (101,102) without slackening the transmission cables (507). This configuration, moreover, makes it possible not to hinder the other elements and increases the stretching points necessary for working with the equipment of the invention, even though the available space is very small.
