Description

{Chair assembly of weight exercise equipment}

The present invention relates to an improved chair assembly of a weight exercise device, more specifically to facilitate the unfolding and folding operation of the chair, as well as to be easily adjusted by a guide rod when adjusting the length of the chair, thereby improving controllability and convenience It relates to an improved chair assembly of a weight exercise device that allows the user to stand the backrest according to the user's convenience.

In general, the weight exercise equipment is divided into exercise equipment for upper body training and lower body training, and these exercise equipment are provided with a weight body that can appropriately adjust the weight according to the user. Muscle exercise 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 strengthens the user's arm muscles. .

Such a weight exercise device includes a guide rod connected vertically to the front and rear support frame bodies vertically installed on the ground, and a guide rod connected vertically to the guide rod, and a barbell rod connected to a vertical movement guide and a guide rod connected to a bearing. It is connected to a vertical exercise guide and consists of a weight body lifted by the motion of lifting the exercise bar and a chair on which the athlete can sit.

Among the methods of exercising using such a conventional weight exercise device, the athlete repeatedly lifts and lowers the barbell bar while straightening the chest and waist after opening his legs narrower than the shoulder width while standing in a straight state. There is an exercise method.

That is, after the athlete selects a weight as much as he or she can lift, the barbell rod is positioned on the back neck of the athlete, the barbell rod is placed on the shoulder of the athlete, and the exercise is performed while sitting up and standing up. To lose.

In this way, when lifting the weight by the movement of lifting the barbell rod, the vertical movement guide connected to the barbell rod by the bearing makes it easy to move up and down and slide along the guide rod, thereby lifting the weight easily. To proceed.

In addition, while the athlete is sitting on the chair, the barbell rod is positioned on the chest of the athlete, and the upper body is exercising while lifting the weight by lifting the barbell rod.

However, there is a problem in that the chair provided in the conventional weight exercise device cannot always utilize the space occupied by the chair because the chair is always in a fixed state when not in use.

Accordingly, in the case of a conventional weight exercise device, since the chair is fixed and the chair is not provided, the weight of each weight exercise device is burdened.

On the other hand, the applicant has devised a weight exercise device, which is a registered patent 10-1940796, to solve the problems of the conventional weight exercise device, which includes a first bearing body, a second bearing body, a third bearing body, and a fourth bearing body. Each of the first guide rod, the second guide rod, the third guide rod, and the fourth guide rod is respectively fitted to the first bearing body, the second bearing body, the third bearing body and the third by the lifting operation of the weight body. 4 The bearing body slides up and down along the first guide rod and the second guide rod, the third guide rod and the fourth guide rod, respectively, as well as the first bearing body, the second bearing body, the third bearing body and the fourth bearing body. The plurality of first bearings and the second bearings provided are positioned in a cross shape crossing with respect to each other so that the outer surfaces of the first guide rod, the second guide rod, the third guide rod, and the fourth guide rod can be simultaneously supported and lifted. The weight of the weight can be distributed, and various weight movements can be performed using a weight exercise rod, an iron rod exercise rod, and a parallel exercise tool.

However, in the case of such a prior art, when the user is in a sitting state, the chair is erected when the chair is erected. At this time, when the length of the chair is varied according to the physical condition of the user, the connection structure between the frame and the frame is As a result, it is difficult to easily change the length of the chair, and thus women with low strength have a problem in that the usability and convenience are not only greatly reduced, but also the movement of the chair is generated when the chair is seated.

Republic of Korea Registered Patent No. 10-1940796 (January 15, 2019 registration) Korea Registered Utility 20-0379536 (Registered on Nov. 2005)

The present invention is provided in the weight exercise device and the length adjustment of the chair hinged to one side of the lower frame of the weight exercise device is guided by a sliding rod so that the length can be adjusted, thus greatly improving usability and convenience and erecting the chair. The object of the present invention is to provide an improved chair assembly for a weight exercise device that allows the chair to stand upright when the chair back is erected, and to prevent the chair from shaking during exercise.

As a means for achieving the above object, the improved chair assembly of the present inventor's weight exercise device is hinged and hinged to the lower frame of the weight exercise device and hinged relative to the lower frame by the hinge to stand or lie down, and The forward and backward support frame body moving forward or backward with respect to the lower frame and the seat frame and back frame provided at the top of the forward and backward support frame body, the chair seat provided in the seat frame and the chair back provided in the back frame, In the chair assembly of a weight exercise device having a chair variable for erecting or lying down the chair back relative to the chair seat, the chair variable includes: a first hinge shaft provided at a lower rear side of the seat frame; A second hinge shaft provided on the front side of the back frame; It includes a chair hinge portion that connects the first hinge shaft and the second hinge shaft so that the back frame is hinged with respect to the seat plate frame so that the seat plate frame is erected or laid, and a fixed shaft is provided at the front side of the seat plate frame. And, by connecting the second hinge shaft of the back frame and the fixed shaft of the seat plate frame to support the seat frame and back frame, a chair flow prevention part is provided to prevent the back frame and the seat frame from shaking, and the back plate A hinge bracket provided at the bottom of the frame; A free rotation roller part provided on the forward and backward support frame body; A bottom guide in which the lower end of the free rotation roller part is in close contact and a shock absorbing port in close contact with the bottom of the back frame is provided at the top, and a variable adjustment pin is fitted; It is inserted through the inside of the backing guide, but one side is connected to the hinge bracket provided at the bottom of the backing frame and is provided along the lengthwise direction so as to correspond to the variable adjusting pin fitted to the backing guide. The paper is made of a variable adjustment guide having a plurality of variable adjustment holes, and a forward/backward sliding body that allows the chair seat and chair back to slide and slide easily when moving forward or backward while the chair seat and chair back are lying down. It is provided.

In the present invention, when a chair made of a chair seat and a chair back is placed against a weight exercise mechanism, the chair is easily and smoothly moved by a sliding bearing portion and a forward and backward sliding rod of the forward and backward sliding body when the chair is advanced or reversed relative to the weight exercise mechanism. As it can move forward or backward, the usability and convenience can be greatly improved, and as the chair seat and chair back are firmly supported when sitting on the chair while lying down, the chair seat and chair back float during the exercise. As it not only prevents shaking, but also absorbs the shock applied to the back of the chair, the user minimizes the transmission of shock to the back and minimizes the transmission of shock to the forward and backward support frame that slides forward and backward. Of course, the robustness can be greatly improved.
