BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a training bench used for weight training.

[0002]

2. Description of the Related Art Conventionally, as a training bench used for weight training, the backrest seat can be changed from a horizontal state to a vertical position, and generally, exercises such as a flat bench press, an incline bench press and a shoulder press can be performed. Various products that can do this have been devised and provided to the market.

That is, as shown in FIG. 5, the backrest sheet 2
The slidable support column 21 is arranged on the back surface of 0, and when training, the position of the stopper 22 is appropriately changed to adjust the height of the slideable support column 21, thereby adjusting the angle of the backrest seat 20. Structured training bench 23 is known

As another structure, as shown in FIG. 6, columns 25 for supporting barbells are erected on both sides of the backrest seat 24, and the columns 25 hold the backrest seat 24. A training bench 27 having a structure in which the angle of the backrest seat 24 is adjusted by screwing a bolt pin 26 to be screwed and changing the position of the bolt pin 26 as necessary is also known.

[0005]

However, these conventional training benches have the following problems to be solved. That is, in these conventionally known training benches, when it is necessary to change the tilt angle of the backrest seat during training, the operator should descend from the training bench each time and pull out the stoppers and bolt pins to mount the backrest seat or slide type. It is necessary to adjust the angle of the backrest seat by lifting or expanding and retracting the columns of, and if the necessary angle can be adjusted at one time,
If you can not adjust to the desired angle, you have to get off the training bench and repeat the same operation again, which is very time-consuming, burdens the user, and buys a bad reputation. Had a drawback.

In these known training benches, even if the seats are fixed, or if the seats can be adjusted with an inclination angle,
Like the backrest seat, it had the drawback of having to get off the training bench and adjust each time.

In view of these drawbacks of the prior art, the present invention allows the backrest seat of a training bench to be tilted while the user does not have to get off the training bench each time, while still sitting at the required angle. The purpose was to supply a training bench that allowed adjustment of seats and seats.

[0008]

To achieve the above object, in the training bench of the present invention, a seat and a backrest seat are arranged on the upper surface of a horizontal frame via a seat spring, and A strut is arranged on the back of the leaning seat, and a stopper portion for adjusting the length of the strut is formed at the lower portion of the strut, and a spring is formed in the stopper portion so that a stopper pin can be inserted into and removed from the strut. Is attached and the wire is connected to the end,
In the reclining type training bench, the wire is connected to a lever attached to the horizontal frame.

In addition, according to another embodiment of the present invention, the front frame and the slide type columns are erected from the front end portion of the grounding frame and the grounding frame, and the rear frame is erected from the rear end portion thereof. A horizontal frame is placed on the columns and the rear frame, and the upper end of the front frame is axially attached to a position of about 2/3 of the total length of the horizontal frame.
The slide type column is axially attached to the front end of the horizontal frame, and the pillar spring is interposed inside the slide type column,
The pillar spring and the locking pin make it possible to vertically extend and contract the slide-type support, the rear frame is pivotally attached to the rear end of the horizontal frame, and the ankle pad has an ankle pad at the front end of the horizontal frame. Place a fork,
The training bench is characterized in that a seat seat and a backrest seat are arranged on an upper surface of the horizontal frame, and a column is arranged on a back surface of the backrest seat.

Further, as another embodiment according to the present invention, a grounding frame, a front frame and a slide column are installed upright from the front end of the grounding frame, and a rear frame is installed upright from the rear end of the grounding frame. A horizontal frame is placed on the slide type post and the rear frame, and the upper end of the front frame is axially attached to a position of about 2/3 of the entire length of the horizontal frame. Is pivotally attached to the front end of the, and a pillar spring is interposed in the inside of the slide type column, and the pillar type spring and the locking pin allow the slide type column to expand and contract vertically, and the rear frame of the horizontal frame. An ankle fork having a pallet fork attached to the rear end of the horizontal frame is arranged at the foremost end of the horizontal frame, and a seat seat is mounted on the upper surface of the horizontal frame via a seat spring. And a backrest seat, and a strut is arranged on the back surface of the backrest seat, and a stopper portion for adjusting the length of the strut is formed at a lower portion of the strut, and a stopper pin is provided on the stopper portion. Is inserted through a spring so that it can be inserted into and removed from a column, and a wire is connected to an end of the column, and the wire is connected to a lever attached to the horizontal frame. It is a training bench.

[0011]

As described above, in the training bench of the present invention, the seat seat and the backrest seat are arranged on the upper surface of the horizontal frame via the seat spring, and the support column is arranged on the back surface of the backrest seat. A stopper portion for adjusting the length of the support pillar is formed in the lower portion of the support pillar, and a spring is inserted through the stopper pin so that the stopper pin can be inserted into and removed from the support pillar. Since the wire is connected to the end and the wire is connected to the lever attached to the horizontal frame, the user contracts by pulling the lever while sitting on the training bench. , Acts like pulling out the stopper pin of the stopper part from the column,
At that time, the spring action of the seat spring interposed between the backrest seat and the seat seat tilts the backrest seat to the required inclination angle, and further returns the lever to extend the wire, in which case the stopper Since the stopper pin is inserted and fixed in the opening of the column by the force of the spring that has been inserted through the pin, the backrest seat can be adjusted without the user having to get off the training bench each time. Becomes

Further, in the present invention, the slide type support is pivotally attached to the front end portion of the horizontal frame, the pillar spring is interposed inside the slide type support, and the slide type is supported by the pillar spring and the locking pin. Adopting a structure that allows the pillars to expand and contract vertically, and at that time, the front frame and the rear frame also freely rotate at the points where they are axially attached simultaneously, so the tilt angle of the seat can be adjusted freely. Is possible. Therefore, unlike the conventional training bench, even when changing the seat seat installation angle, by pulling out the locking pin, the elasticity of the pillar spring interposed in the slide-type column makes it easy to lift the seat seat. In addition to changing the angle, when the seat is returned to its original position, pulling out the locking pin and applying weight to the seat, the slide-type support will contract and easily return to its original state. As it is not necessary to get off the training bench and adjust each time, the training efficiency is also improved.
