Description

TECHNICAL FIELD

The present invention relates to exercise apparatuses. More specifically, the present invention relates to an exercise apparatus which enables a user to exercise and relax his/her muscles.

BACKGROUND ART

In recent years, weight training or many kinds of muscle training has been conducted for various purposes. Such training is becoming widely popular among not only athletes but ordinary people including elderly persons, because they can develop necessary muscles as well as maintain and improve their health.
However, training may bring about various problems. For example, improper weight setting may apply an overload to the muscles of a person or may cause the rapid blood pressure rise.
On the other hand, current office automation is prone to force people to keep improper or the same pose for a long time. As a result, they suffer from a spinal curvature, backache or stiff neck. Hence, training apparatuses by which those troubles can be overcome have been in demand.

DISCLOSURE OF INVENTION

Accordingly, an object of the present invention is to provide an exercise apparatus which is applicable to both athletes and ordinary users by giving appropriate loads.
Another object of the present invention is to present an exercise apparatus which makes it possible to strengthen the muscles around the spine, hip joint, etc. of a user, thereby mending his/her backache or stiff neck during an exercise.
As a result of thorough study on the above objects, the inventor, et al. have found a fact that proper exercises are possible by subjecting muscles to appropriate relaxing and loading movements. Moreover, the inventor, et al. have discovered various exercises that are applicable to muscles, based on a result of further study on this fact.
Thus, the present invention is an exercise apparatus for exercising muscles, which is constituted of an exercise main body and a loading part. In addition, the loading part is configured to move in directions where a load is applied to the muscles and where the muscles are relaxed.
The above exercise apparatus is applicable to various apparatuses including dip, chest press, lat pull down, total hip, leg press and hip adapter apparatuses.

BEST MODE FOR CARRYING OUT THE INVENTION

An explanation will be given below, of embodiments of the present invention, with reference to attached drawings. However, the present invention is not limited to these embodiments. Any exercise apparatus should fall within the scope of the present invention as long as possessing two functions: a function of relaxing muscles on purpose (thereinafter, merely referred to as a “relaxing movement”) and a function of applying a load to muscles (expand movement: thereinafter, merely referred to as a “loading movement”). In each of the embodiments of the present invention, typically the relaxing movement is done at first, and followed by, the loading movement is done. However, the present invention is not limited to this order. Alternatively, the relaxing movement may be done after the loading movement, or both movements may be repeated alternately.
Note that the term of an “exercise” herein means that both relaxing and loading movements are applied to the muscles of a user. Hence, said exercise is distinct from conventional exercises representing the loading movement alone.

First Embodiment

Dip

First, a dip apparatus 100 according to a first embodiment of the present invention will be described. FIG. 1A is a schematic view of the exercise apparatus according to the first embodiment of the present invention, and FIG. 1B is a view showing muscle portions exercised by this exercise apparatus.
The dip apparatus 100 mainly comprises a seat part 101 on which a user is to sit, an exercise part 102 including grip means 102 a and 102 b which are a predetermined distance away from each other in such a way that the user takes hold of them with their hands, and an arm 102 c which is joined to the grip means and which is parallel to the horizontal surface of the seat part, and a loading part 103 which is coupled to the exercise main body and which applies a load thereto. Materials of this apparatus are not limited to specific ones as long as the objects and effects of the present invention are not impaired. Accordingly, they may be selected appropriately among conventionally known materials (e.g. metal such as steel or aluminum, ceramic, plastic and carbon).
The dip apparatus 100 according to the first embodiment of the present invention is an apparatus for exercising a latissimus dorsi muscle, a rhomboideus muscle, a deltoid muscle, biceps brachii muscles and a trapezial muscle, and it is configured to perform the relaxing movement in addition to the loading movement which conventional dip apparatuses carry out.
Specifically, the loading part 103 mainly includes loading means (for example, weights) for applying a downward, vertical load to the exercise part 102 with respect to the seat part, coupling means for transmitting the load of the weights to the exercise part 102 (also having the same function in the following embodiments), and relax direction moving means for moving the exercise part 102 in the direction opposite to that in which the loading mean gives the load.
The coupling means may be composed of a chain, a reel around which the chain is wound, and a shaft for transferring the load of the loading means to the exercise part 102, as shown in FIG. 1A. Further, the relax direction moving means can be implemented by setting the margin of the length of the chain (in the upper portion in this embodiment) for the relaxing movement or by switching the directions using a gear (the same fashion applying for the following embodiments).
Alternatively, the loading and relaxing movements may be switched by a switch, etc. as needed.

(Operation)

In the dip apparatus 100 of this embodiment, a user first sits on the seat part 100 and, then holds the grip means 102 a and 102 b with both hands, respectively.
Subsequently, the user lifts up the exercise part 102 (in the direction “R” of FIG. 1A). During this operation, the latissimus dorsi muscle, rhomboideus muscle, deltoid muscle, biceps brachii muscles, trapezial muscles, etc. shown in FIG. 1B are relaxed (the relaxing movement).
Following this, the user pushes down the exercise part 102. This operation is in this way (in the direction “L” of FIG. 1A).
An operation of a conventional dip apparatus is only to push down the exercise part 102. In contrast, the dip apparatus 100 of this embodiment presents both relaxing and loading movements.
Those two movements allow the slide movement of the blade bones, thereby expanding the movable range of the shoulder joints. In addition, since the blade bones rotate upward, the movable range of the shoulder joints is also expanded. This results in the enhancement of flexibility of the muscles around the shoulder joints, which is effective to stiff necks. Especially, those two movements have an effect on stiff necks from which many women suffer. Moreover, they effectively allow athletes to acquire a smooth golf swing and prevent them from sustaining tennis and baseball elbows.

Second Embodiment

Chest Press

Next, a description will be given, of a chest press apparatus 200 according to a second embodiment of the present invention. FIG. 2A is a schematic view of the exercise apparatus according to the second embodiment of the present invention, and FIG. 2B is a view depicting muscle portions exercised by this exercise apparatus.
As shown in FIG. 2A, the chest press apparatus 200 is an apparatus for mainly exercising a greater pectoral muscle, triceps brachii muscles and deltoid muscles. Furthermore, it mainly includes a seat part 201 on which a user is to sit, an exercise main body 202 that is constituted of an arm portion placed surrounding the seat part 201 and that can be held by the user while sitting and stretching his/her arms upward, and a loading part 203 that is placed parallel to the exercise main body and behind the seat part, that is coupled to the exercise main body, and that gives a load to the exercise main body forward and backward.
The loading part 203 gives a forward load to the loading part and is movable backward with respect to the loading part (refer to the loading part 103 of the first embodiment as to a movement mechanism of the loading part 203).

(Operation)

In the chest press apparatus 200 configured above, a user first sits and, then straightens his/her spine by holding the upper parts of the arm portion of the exercise main body 202 while opening his/her arms. When the user moves the exercise main body 202 backward (or toward the loading part 203), his/her muscles are relaxed. Then, when he/she moves the exercise main body 202 forward, the muscles undergo a load. During the above operation, the greater pectoral muscle, triceps brachii muscles, deltoid muscle, etc., are exercised, which is effective to slight stoops, stiff shoulders due to age and baseball shoulders. In other words, muscles related to breathing which are throughout the chest are stretched. This makes it possible to expand the movable range of the shoulder joints and to enhance the flexibility of their surrounding muscles, thereby having an effect on stiff necks. In addition, the spine is made in a proper position, thus ensuring an excellent pose.
Moreover, the chest press apparatus 200 of this embodiment can be used effectively by athletes to acquire a smooth golf swing and to prevent their tennis and baseball elbows.
This effect cannot be realized simply by moving muscle under load conditions as in a conventional chest press apparatus, but can be achieved only by the apparatus of this embodiment.
Furthermore, this apparatus allows a user to do pullover so that his/her back muscles are stretched.

Third Embodiment

Lat Pull Down

An embodiment will be given, of a lat pull down apparatus 300 according to a third embodiment of the present invention. FIG. 3A is a schematic view of the exercise apparatus according to the third embodiment of the present invention, and FIG. 3B is a view depicting muscle portions exercised by this exercise apparatus.
As shown in FIG. 3A, the lat pull down apparatus 300 of this embodiment is an exercise apparatus for mainly exercising a back muscle and biceps brachii muscles. Furthermore, it mainly includes a seat part 3001, an exercise main body 302 that is positioned above a user and that has arm parts to be held by the user while he/she is stretching the arms, and a loading part 303 that is coupled to the exercise main body 302 through a strip-shaped body such as a chain and that gives a vertical load thereto.
The seat part 301 is a seat part to be sat by a user and is inclined forward. If a user sits on the forward-inclined seat part 301, then his/her spine is straightened, that is, is kept in a proper pose.
The exercise main body 302 has a straight shaft with both ends bent downward as shown in FIG. 3A, and grips, etc, attached to the ends of the shaft in order for a user to hold easily.
The loading part 303 includes a loading device, such as weights, coupled to the exercise main body 302 by a chain, etc., and further includes a load adjustment means, such as gears, between the exercise main body 302 and the weights. The load adjustment means is configured to switch between the downward loading and upward relaxing movements.

(Operation)

In the above-configured lat pull down apparatus 300 of this embodiment, a user sits and straightens his/her spine by holding the exercise main body while opening the arms. Then, when the user moves the exercise main body 302 to information, his/her muscles are relaxed. Subsequently, when he/she moves the exercise main body 302 downward, the muscles undergo a load. Those movements allow the back muscle, biceps brachii muscle, etc. as shown in FIG. 3B to be exercised. When the user applies a pull force toward the center of his/her body, the output of the muscles is transferred to their ends. This makes it possible to acquire flexible, elastic muscles which are applicable to various competitions, and to expand the movable range of the shoulder joints.
As a result, ordinary users can benefit from the improvement of stiff necks, stiff shoulder due to age, baseball shoulders, migraine due to stiff necks and palsy due to stiff neck, and athletes can obtain the sharp movement of the waist.

Forth Embodiment

Total Hip

Next, a description will be given, of a total hip apparatus 400 according to a forth embodiment of the present invention. FIG. 4A is a schematic view of the exercise apparatus according to the forth embodiment of the present invention, and FIG. 4B is a view depicting muscle portions exercised by this exercise apparatus.
As shown in FIG. 4A, the total hip apparatus 400 of this embodiment is an exercise apparatus for mainly exercising muscles around hip joints and a hip, adducent muscles and abducent muscles. In addition, it mainly includes an exercise main body 401 composed of an arm part on which a leg of a user is to be set and which is provided in such a way that the leg is movable in a circular motion around the base of the leg, and a loading part 402 which is coupled to the exercise main body 401 and which gives a load thereto. The loading part 402 gives a load while moving in a downward circular motion, and is also movable in an upward circular motion.

(Operation)

In addition, athletes can use it to strengthen their hip joint and to acquire flexibility of the hip joint.

INDUSTRIAL APPLICABILITY

As described above, although conventional training methods are to lift up heavy weights for the purpose of increasing the maximum muscle strength, the exercise apparatus of the present invention involves slash back movements at a light load at an appropriate speed to thereby increase the peak of a muscle force even by using the same weights. This is because the relaxing movement using the decreased load and the loading movement using the increased load are switched at an appropriate timing. Thus, the exercise apparatus of the present invention could combine stretch and weight trainings and advance them. Apparatuses of this type have been available to basically provide ballistic workout. However, since involving quick movement, they are not appropriate to especially middle-aged and elderly persons. In contrast, because the exercise apparatus of the present invention permits a user to change his/her pose with a proper rhythm, the user can work out safely without undergoing any excessive stress.
The exercise apparatus of the present invention provide users to essential ballistic workout, as well as to rhythmically contract and relax his/her muscles while surrendering him or her to the weights. This enables a user to keep his/her body relaxed without undergoing excessive loads. Thus, it is possible for users to acquire a flexible, elastic body, thereby leading to the decrease in the risk of injury. Moreover, this apparatus can improve the circulation of blood and metabolism of users, which is effective to anti-aging, fat removal and a rehabilitation exercise for sick persons except for those having a locomotor disability.
A training method using the exercise apparatus of the present invention rhythmically guides the compression and relax of muscles of a user by using light weights. In this case, the blood circulation of distal vein of a user is naturally facilitated. Consequently, the user can feel that his/her body is light, that is, comfortable, even when exerting a force. Furthermore a user can breathe evenly and show the stable circulatory system response, which has an effect on the recovery from fatigue and the removal of fatigue-producing substances. Therefore, the exercise apparatus of the present invention has potential for various applications.
The exercise apparatus of the present invention is also possible to enhance the talent of top athletes, but it is more effective to persons who hope to maintain their health or to prevent the decline of their strength and athletic talent. It can be greatly expected that disable persons due to accident or sick or elderly persons are able to recover the body functions or control their health.
Note that either a motion of expanding, retracting and expanding muscles in this order or a motion of retracting, expanding and retracting muscles in this order can satisfy the expectation for the above effects.
