Description

1260235 V. OBJECT OF THE INVENTION (Using the Technical Field of the Invention) The present invention relates to an improvement of a lacing machine, in particular, an improved structure in which a shank of a lacing machine for gripping a handle of a user has moderate flexibility. The prior art lacing machine, as shown in FIG. 8 , mainly has an I-shaped base 5 , and the base 5 is pivotally connected with a bracket 6 , and the bracket 6 is provided with a seat for the user to ride. The pad 6 1 and the plurality of legs for the user are abutted against the pad body 6 2 , and the bracket 6 is pivotally connected to the two sides of the base 5 respectively for a pedal 6 3 for the user's foot to step on, and the base 5 A pole 5 1 is disposed at a front end of the bracket 6 , and a grip 5 5 for the user to hold is respectively disposed on both sides of the top end of the pole 5 1 ; thereby, the user sits in a kneeling position during use On the seat cushion 61, and the two legs are abutted against the cushion body 62, and the grips 5 2 are held by both hands, and the strength of the hands is used to prop up or pull the body, so that the body swings with the bracket 6. And achieve the effect of the lacing. Because the lacing machine is swinging the body to move the lacing, it is the stand of the two hands. Supporting or pulling the body to swing, and the force applied by the hands is on the grips 5 2 disposed on both sides of the uprights 5 1 , but the uprights 5 1 is an inflexible rod, which cannot be produced Moderate flexibility, if the flexibility of the two hands is not enough, it is easy to make the hands and arms uncomfortable, and easy to increase the fatigue of hands and arms, long-term use, but will cause the user's hands And the sports injury of the arms. Further, when the lacing machine is used, the user can stand on the crossbar 5 3 at the rear end of the base 5, and hold the seat cushion 6 1 with both hands and stand up to make the legs Reaching the effect of the lacing, however, the crossbar 5 at the rear end of the base 5 of the lacing machine

1260235 V. INSTRUCTIONS (2) The 3 series is a square body with a square cross section. When the user's feet are stepped on the crossbar 5 3, the corner of the crossbar 5 3 tends to exert pressure on the bottom of the sole. This creates an uncomfortable pain and reduces the user's willingness to use the part to stretch. Therefore, how to improve the lack of the vertical rod and crossbar structure of the conventional lacing machine is the focus of the improvement of the present invention. SUMMARY OF THE INVENTION The main object of the present invention is to solve the above problems and provide an improvement of a lacing machine, which includes a base and a swingable bracket pivoted on the base, the front end of the base Each has a front foot frame and a rear leg frame, and the base pivotally connects the bracket between the front and rear legs, the front leg frame has an upwardly extending pole for pivoting an extension rod having a handle, and the bracket Fixing a cushion and a pad on the top, wherein the top end of the pole has a body for pivoting the extension rod, and a bottom of the base body extends a stop surface toward the rear leg frame, and the The seat body has a retaining wall on one side of the rear leg frame, and the extension bar is provided with an elastic body corresponding to the bottom of the blocking surface for abutting against the stopping surface, and the extending rod corresponds to one of the retaining walls A cushion is provided on the side for the inner side of the retaining wall. The tensioning lever is pivotally connected to the base of the top end of the pole, and the extension rod is provided with an elastic body and a cushion corresponding to the seat body. The body is pivoted forward and backward on the vertical rod by the elastic deformation of the elastic body and the cushion body, so that the extension rod has moderate flexibility, so that when the user holds the handle to apply force, With the flexibility of flexibility, it can avoid the fatigue of the hands and arms of the user.

1260235 V. INSTRUCTION DESCRIPTION (3) The second object of the present invention is to stand on the tripod after the user stands on the base to pull the legs, since the hind legs are elliptical in cross section. The tube body, so that when the user steps on the rear leg frame, the user does not feel uncomfortable, and the user steps on the arc segment of the rear leg frame, and the arc of the curved segment is curved in accordance with the user's standing feet. The angle makes the user easy to stand for the lacing action; the arc segment is provided with a slip pad for the user to step on, which can increase the stability of the user's standing. The above and other objects and advantages of the present invention will be readily understood from Of course, the invention may be varied on certain components, or in the arrangement of the components, but the selected embodiments are described in detail in the specification and their construction is shown in the drawings. [Embodiment] Please refer to Fig. 1 and Fig. 2, which shows the structure of the embodiment selected for the present invention, which is for illustrative purposes only and is not limited by this structure in the patent application. The invention is an improvement of a lacing machine, which mainly comprises a base 1 standing on the ground, and a bracket 2 pivoted on the base 1 , wherein the front end and the rear end of the base 1 respectively The utility model has a front stand 1 1 and a rear stand 1 2 , and the two ends of the front and rear legs 1 1 and 1 2 are respectively sleeved with a foot pad 1 1 1 and 1 2 1 for the base 1 to be stably supported on the ground. The base 1 has a pivoting seat 13 between the front and rear legs 1 1 and 12 for pivoting the bracket 2.
