Description

ABDOMINAL EXERCISE TEAM WITH MECHANISM

INTERNAL RESISTANCE

Field of the Invention

The present invention relates to an abdominal exercise equipment with adjustable resistance means and more particularly, it relates to a novel abdominal exercise equipment with adjustable resistance means located within its internal frame with work elements for legs and arms, and which also has mechanisms that allow to extend the base of the equipment to adapt it to the performance of different routines of erection.

Background of the Invention

Among the conventional routines of ej ercitación, those focused on training the abdominal region are the most difficult to carry out, since most people do not have enough strength to perform them properly, so they give up his attempts to improve the tone of his abdominal muscles by not seeing significant improvements even after a long time of practicing abdominal routines or suffering injuries. Although, with the passage of time, some of these people manage to maintain a constant exercise routine they do not always achieve the desired results.

In order to facilitate abdominal erection routines and / or improve the results obtained, Developed teams such as erectors that provide the necessary support to improve the user's posture during the performance of the abdominal routines, thereby improving the chances of obtaining notable benefits with the training of the abdominal muscles. These teams provide a certain degree of active resistance to natural movements of the body, which improves the results obtained when performing abdominals and some at the same time provide active support thereby limiting the presence of injuries.

These training equipment also improves the user's posture and serves as a guide to carry out the training routines correctly, which significantly improves the results of the physical training, so that with a shorter time it is possible to obtain better Results in the training of the abdominal muscles. This type of training equipment is shown, for example, in US Patent Application 20080318745, which describes an exercise equipment of the type "horizontal crunch, which has a tilting bar with resistance at one of its ends that is connected by a series of connecting members that connect the tilting bar with the seat of the equipment so that a coordinated lifting mechanism is created that coordinates the ascent of the tilting bar with the lifting of the seat to simulate horizontal crunch routines. since it is used by multiple connections, it is very likely that the equipment will fail; also, due to the large number of joints, the use of lubricants in the equipment is required to maintain its proper functioning. coordinated both surfaces, it is not possible to lead to other types of training routines.

US5665041, discloses an exercise equipment for abdominal exercise routines in which the leg support is connected by a transmission mechanism to the back support of the equipment. In such equipment, only simulation of crunch routines can be carried out and it is not possible to train the user's legs or abdomen individually. Likewise, the equipment described in the aforementioned patent cannot be folded to reduce its dimensions and due to the complexity of its connection mechanism it is subject to accelerated wear.

US 6206809 B1 discloses a rigid frame exercise equipment to which a tilting arm with padded surfaces for receiving the ankle of the user is attached at its back. Such equipment offers resistance to movement through an adjustable resistance wheel mechanism that uses the user's weight as a source of resistance; however, when doing this, the intensity of the routine cannot be regulated since the force applied to the user cannot be controlled in different degrees.

US 6387024 B1 protects an abdominal equipment that has a telescopic arm located at the back. This equipment has an adjustment disc that allows varying the angle of inclination at will. On the other hand, the equipment comprises a resistance bar attached to a regulator disk coupled to an actuator hydraulic. Although with the proposed resistance scheme it is possible to obtain different degrees of intensity in the equipment, its resistance can only be applied to the back region without the legs being able to be trained separately.

Patent application CN 106310598 describes an abdominal exercise equipment that has a central support bar with an internal spring-formed resistance mechanism. This equipment only has a support base and does not have any type of mechanism for leg training, so abdominal compression routines can only be carried out in which resistance is carried only in the region of the back of the user.

None of the equipment for performing abdominal routines described above has individual resistance mechanisms for the leg support arms and the back support, so different types of training routines cannot be done. Likewise, none of the equipment described above has modifications that allow it to be folded in order to reduce its effective storage area, to which must be added the fact that their mechanical systems being so complex are subjected to accelerated wear that reduces the life of the equipment.

In view of the above problems, there is a need to provide an abdominal exercise equipment with adjustable resistance mechanisms included in its support frame, which are also discrete and that do not protrude from its internal framework. There is also a need to provide an exercise equipment with an extensible framework that allows the equipment to be extended in order to adapt it to the performance of different training routines while facilitating its storage in confined spaces. Moreover, there is a need to provide an abdominal exerciser with mechanisms included to also exercise the user's legs providing a resistance adjustable to them.

Summary of the Invention

In order to overcome the disadvantages of existing abdominal training equipment, the present invention aims to provide an abdominal exerciser with internal adjustable resistance mechanisms.

A particular objective of the present invention is to provide an abdominal exercise equipment with means for performing "V" lifting routines in which an active resistance directed to the area of the user's back and legs is involved.

Another objective of the present invention is to provide an abdominal exerciser with means for performing leg lifting routines with rotation.

A further objective of the present invention is to provide an abdominal exerciser that can be folded both in height and length to facilitate storage.

The aforementioned objectives, as well as others and the advantages of the present invention, will become apparent from the following detailed description thereof.

Detailed description of the invention

The present invention provides a new abdominal exercise equipment with an extendable central load frame, with means for regulating the resistance to the extension of the equipment formed by an internal resistance mechanism hidden within the equipment. Also, the present invention provides an exercise equipment with an extensible support frame that allows to increase the area of effective surface that the equipment occupies in order to guarantee the correct settlement of the same on the support surface in order to adapt to the realization of different routing exercises, which at the same time favors its storage in small spaces when contracting the frame If necessary. Additionally, the present invention provides an exercise equipment with resistance arms for legs and back that allows to carry out different routines of erection.

To achieve the foregoing, the present invention comprises a central support frame; an anterior swing arm and; a rear swing arm. Their construction and function will be described in more detail below.

Central support frame

The central support frame comprises:

• a main support (1) in the form of "L" which is constituted by the two sides (2) joined together by a distal base (3) with means to engage a crossbar

(4) that serves as the basis of the equipment and, by a welded plate

(5) located at the opposite end of the distal base (3), which has a screw lock (a). Said support (1) has, a pair of squares (6), located on the sides of the sides (2), located near the middle part of the welded plate (5), being made a pair of perforations (7) a each side of the squares (6) to receive a set of guides (8) that are placed on the inside of the sides (2), with a base being supported of seat (b) with a central groove on said squares (6) and;

• a secondary support (9), which is received in the guides (8), consisting of a bent tubular ending at a distal base (10) with means to engage a stringer (11) that serves as the second base of the equipment, said secondary support having at its other end a receiving base (12) with a first (I) and a second (II) coupling holes, for the reception of the front swing arm, such that when passing the secondary support (9 ) along the guides (8), the total length of the equipment can be controlled, securing the secondary support (8) inside the main support, by means of the screw lock (a).

In a preferred embodiment of the present invention, the seat base (b) has a cushioned surface (c) that has a central groove that corresponds to the groove of said seat base (b).

Anterior swing arm (A)

The front swing arm (A), is constituted by a tubular that has a head (13) in the form of "T" located at its free end, which has a pair of protectors (14); a support plate (15), located at the end opposite the head (13), which has a pair of extensions that are attached to the first coupling hole (I) of the receiving base (12) by means of screws, so that the swing arm (A) can pivot on the axis formed by these two structures and; an internal resistance mechanism consisting of a spring (16), which is anchored to the second coupling hole (II) of the receiving base (12) and to an internal support (17) that is fixed inside the swing arm (A), in such a way that the swing arm (A) when extending causes the elongation of the spring (16), which generates resistance to the extension movement of said swing arm. This tilting arm (A) has the function of receiving the user's high back to exert an upward force when it is pushed back during the training routine and at the same time allows the arm to be folded in the opposite direction without any type of return force.

In one of the preferred embodiments of the present invention, the internal support (17) is fixed to a series of perforations (18) in the swing arm (A), by means of a push button mechanism located in the internal support (17), so that the resistance to the extension of said swing arm (A) can be regulated, by regulating the extension of the spring (16), thus providing up to 4 levels of resistance of the equipment; likewise, said resistance mechanism allows the tilting arm (A) to be folded horizontally to its maximum extent.

In a further embodiment of the present invention, the swing arm resistance mechanism (A) can be part of an abdominal double-arm equipment (Figure 4). In this modality the equipment consists of a base in the form of "U" (III), to which a pair of reception bases (12) are attached at its ends, said base having a form of "U" (III) an internal support surface (IV); a pair of "L" shaped tubulars (V), with perforations (18), which are connected by screws to the first coupling hole (I) of each of the reception bases (12) by means of support plates (15) ) Y; a pair of resistance mechanisms, located inside each of the "L" shaped tubulars (V), formed by the spring (16), which is fixed on one side to the second coupling hole (II) of the reception base (12), while at the other end it is fixed to the internal support (17), said internal support (17) being selectably fixed in the perforations (18) by means of a push button mechanism, allowing to select the angle of inclination of each one of the tubular ones in the form of "L" (V), at the same time that the resistance of the equipment is modified. In this modality, the resistance of each of the tubular ones in the form of "L" (V) can be regulated independently to have the possibility to also perform routines with arms and legs, such as push-ups, bicycles, push arms or funds or; in a coordinated way to function as a back support during abdominal or bridge routines.

In a variant of the modality described in the previous paragraph, the reception bases (12) are covered by a housing (VI), while the terminal ends of each of the "L" shaped tubulars (V) are covered by padded rollers (VII), which provide protection to the user's back, particularly to the infraspinatus, trapezius and major round muscles, when the user performs exercise routines with the equipment. Rear swing arm (B)

The rear swing arm (B), is constituted by a tubular (19) that has in its upper part a crossbar (20) with calf supports (21) and, a bushing (22) located at its other end; a rotating base (23), with perforations for receiving the tubular (19) in a tilting manner, said rotating base (23) having an insertion bolt (24) protruding from its lower part; a cylindrical slip (25) that is placed on the insertion bolt, which is received in a jacket (26) that is welded near the apex of the main support (1) and; an internal resistance mechanism formed by a spring (27), which has a first traction cable (28) that rests on the bushing (22) and is then fastened by screws to a square-shaped extension (23 ') located in the upper part of the rotating base (23) and, a second traction cable (29) attached to an internal support (30) which is supported by an adjustment knob (31) that allows to regulate the tensile force of the spring (27 ) by modifying its extension length. The function of the rear rocker arm (B) is to offer resistance to the movement of lowering of the legs during abdominal routines that involve leg lifting and also allows to perform leg lifting movements with rotation and, at the same time, this arm Rear swingarm can be folded in the opposite direction without resistance.

In a preferred embodiment of the present invention, the swing arm (B) has a lock that allows said swing arm (B) to be locked at an angle between 70 ° and 90 ° with respect to the horizontal of the central support frame, in such a way that the user's legs can be retained with the knees of this at a 90 ° angle to be able to carry out high abdomen routines with raised legs.

In another of the embodiments of the present invention, the main support (1) in the form of "L", further comprises a housing (32) located at its apex, which covers the jacket (26), to prevent the user from being able to accidentally inserting its lower extremities into the space between the shirt (26), the two sides (2) and the distal base (3) in order to prevent injuries.

The abdominal exercise equipment described above can be folded by retracting the secondary support (9) into the main support (1) to its minimum extent, at the same time as the anterior swing arm (A) and the rear swing arm ( B) into the equipment (Figure 3). In this position, the abdominal exerciser equipment of the present invention can be stored in small spaces since its length and height are significantly decreased. Also, due to the conformation of its resistance mechanisms, there are no exposed parts of them, which avoids jams with the user's clothing or with any accessory that it carries.

The present invention has been described in accordance with its preferred embodiments; however, it will be apparent to a technician with average knowledge in the field, that modifications may be made to the invention, without departing from its spirit and scope.
