Description

Smith machine with adjustable angle and swing

The present invention relates to a Smith machine, and in particular, to a Smith machine that allows the movement angle of a barbell to be adjusted by using a manual or an electric motor to further subdivide an exercise area to perform a muscular workout.

Weight exercise equipment is divided into exercise equipment for upper body training and exercise equipment for lower body training, and these exercise equipments are equipped with a weight that can properly adjust the weight according to the user, and exercise the muscles of the user's upper or lower body by the weight. This is being done.

For example, the lower body exercise device is an exercise device that strengthens the calf and thigh muscles of the user's lower body, and the upper body exercise device is an exercise device that strengthens the user's back and shoulder muscles or the user's arm muscles. .

Among such exercise equipment, there is an exercise equipment called Smith Machine, which consists of two support frames positioned to correspond to both sides, a barbell rod that is hung between the two support frames, and a disc-shaped weight that is inserted into the ends of the barbell rods. The user performs an exercise after inserting a disc-shaped weight as much as the weight he can lift into the end of the barbell rod.

In the case of the support frame, it served only as a guide so that the barbell rod could be raised and lowered.

In the barbell exercise, a specific part of the muscle can be stimulated according to the angle when the barbell is lifted, but the existing Smith machine has a limitation in stimulating the muscle because it is fixed at a single angle.

In order to overcome this limitation, the present inventor has filed a domestic patent application No. 10-2016-0149279 "Smith machine with adjustable angle and swing".

On the other hand, the inventors' prior invention had a disadvantage in that the construction was somewhat complicated, resulting in an increase in manufacturing cost and heavy load.

In describing the present invention, only one of the products will be described because the product is left and right symmetric.

The frame part (2) includes two vertical posts 22 and a horizontal beam 24 connecting the upper ends of the two posts, and the support bases 26 are mounted in a'b' shape on both sides of the lower side. Supporting force can be provided.

The swing part (4) is composed of a vertical column (42) that is hinged to both sides of the base (26) with a shaft member (41), and a support member (43) connecting the upper ends of the both side columns (42), and each column The guide portion 6 made of the rack bar 44 is included in 42.

An angle gauge 150 is formed at the end of the shaft member 41.

The angle gauge 150 has a number and an indicator so that the inclination of the swing unit 4 can be measured visually.

The guide part 6 is integrally coupled to the swing part 4 and swings together to guide the rising or falling of the barbell bar 100.

The guide part 6 includes a vertical lifting guide rod 62 in parallel with the pillar 42, and a socket 64 that is coupled to the lifting guide rod 62 to move up and down, and the socket 64 The barbell bar 100 is connected, and a hook 102 is formed on one side of the barbell bar 100 to be coupled to any one of a plurality of locking projections 442 of the rack bar 44 to be fixed in height.

The shaft member 41 is formed horizontally by protruding from one side of the column, and is hinged to enable rotation by being coupled to the bearing 412 of the support base 26.

The angle adjusting part 7 is fixed to the upper end of the shaft member 41 formed on one side of the pillar 42 of the swing part 4 and formed vertically downward through the slit 260 of the support base 26 A swing body 72 composed of an extension panel 722 and a bracket panel 724 formed at a lower end of the extension panel 722; A plurality of elastic members (C1, C2) connected to the support base 26 and the swing body 72 are formed symmetrically on both sides, thereby preventing a sudden inclination when the swing angle of the swing unit 4 changes. It is configured to include; a load support portion 74 that compensates for and exerts a supporting force.

More specifically, the plurality of elastic members C1 and C2 will be classified into first and second elastic members C1 and C2 for convenience of description.

According to an example, the first elastic member C1 has one end fixed to the first holder 741 formed on the support base 26, and the other end formed on the bracket panel 724 of the swing body 72 ( 742).

The second elastic member C2 has one end fixed to the third holder 743 formed on the base 26, and the other end connected to the fourth holder 744 formed on the bracket panel 724 of the swing body 72 Is installed.

Therefore, the first and second elastic members C1 and C2 have an elastic force acting in opposite directions to each other, so that they can exert a complementary force when the swing unit rotates angularly.

According to an embodiment, the first and second elastic members C1 and C2 are coil springs.

The first and second elastic members C1 and C2 described above may be installed to be bent by winding an intermediate portion on a roller 263 formed on the support base 26.

By this bending shape, any one of the first and second elastic members C1 and C2 may be installed in a'b' shape or a'c' shape.

The first and second elastic members C1 and C2 do not have a structural connection with the first and second

angle adjustment brackets

75 and 76.

Therefore, when the swing body 72 is inclined to one side, one elastic member C1 is contracted and the other elastic member C2 is elongated.

For this reason, the weight is compensated according to the slope of the swing unit 4, so that the angle can be easily adjusted without any effort even with the force of one hand.

Meanwhile, a row sensor 36 for detecting the lowest point of the barbell bar 100 is formed.
