Abstract

Disclosed is a sporting apparatus for handstand which makes it possible to protect a user'"'"'s ankle, knee and waist during an exercise by distributing the loads which focus on a user'"'"'s ankle while a user'"'"'s lying-down posture with his back on a backrest board is rotated to a handstand posture, so a weak and old person or a user whose bones can easily fracture can do exercise in safe. The sporting apparatus comprises a base mounted on the ground and having a handle being installed on the upper side of it; a backrest board which is rotatably hinged to the base and supports a user'"'"'s back; an angle-shaped lower body mounting part which is integrally engaged to a lower side of the backrest board and on which is disposed a sitting board allowing a user to sit on it, an ankle fixing rod is formed at a lower side, and bumper part connecting the backrest board and the base while providing a bumper force.

Claims

1. A sporting apparatus for handstand, comprising:

a base 2 including a connection part 26 which is mounted on the ground and is hinged by way of a pivot pin “

P”

after the upper sides of a pair of front legs 22 and a pair of rear legs 24 are crossed and connects the front legs 22 and the rear legs 24, with a handle 28 being installed on the upper side of the base 2;

a backrest board 3 which is rotatably hinged to the base 2 and supports a user'"'"'s back;

a lower body mounting part 4 including a support part 44 which is integrally engaged to a lower side of the backrest board 3, with an ankle fixing rod 445 being formed at its lowers side, and with a popliteal fossa engaging rod 446 being formed at its upper side, and a sitting board 42 formed on an upper side of the support part 44; and

a bumper part 5 which is configured to connect the backrest board 3 and the base 2 while generating a bumper force.

2. The apparatus of claim 1, wherein the backrest part 3 comprises an upper board 32 and a lower board 34 which are foldable, and a frame “

F”

connecting the upper board 32 and the lower board 34, and a folding part 36 is formed at the frame F, so the upper board 32 and the lower board 34 can be folded.

3. The apparatus of claim 2, wherein the folding part 36 comprises:

a first engaging part 361 one end of which is open, and a cross section is formed in a U-shape and which is installed at the upper board 32; and

a second engaging part 362 which is rotatably engaged to the first engaging part 361 by means of a pivot pin 363 and is installed at the lower board 34.

4. The apparatus of claim 1, further comprising:

a position setting part 6 which is configured to limit a rotation angle of the backrest part so that the lowest position and the highest position of the backrest board 3 can be limited, and the position setting part 6 comprises an engaging part 62 which is attached to the rear legs 24 and has a plurality of engaging grooves 622, and a stopper 65 which is hinged at the rear legs 24 and is caught on the engaging groove 622.

5. The apparatus of claim 1, further comprising:

a fixing band 422 which is provided at both the end portions of the sitting board 42 for thereby binding and fixing the user'"'"'s thighs.

6. The apparatus of claim 1, wherein the support part 44 is formed in an angled shape when viewing it from its side, and two pipes 441 and 442 are inserted and engaged to a lower side for the sake of a height adjustment, and a pin 444 is inserted into each pin hole 443 formed at a side surface, and an insertion and engagement structure is formed at an end portion of an engaged portion 445 of the support part 44 and the backrest board 3, so the distance can be adjusted by inputting or disengaging the support part 44.

7. The apparatus of claim 1, wherein both ends of the connection part 26 are hinged to the front legs 22 and the rear legs 24 by way of a pivot pin and can be assembled or disassembled, and a hinge part 263 is formed at an intermediate portion, so it can be foldable.

8. The apparatus of claim 1, wherein said bumper part 5 is configured to prevent a prompt descent and ascent of the backrest part 3, with one end of which being hinged to the rear legs 24, and the other end of which working as a gas-filled shock absorber hinged to a side surface of the backrest part 3.

9. The apparatus of claim 1, wherein there is provided a neck towing part 7 at an upper side of the backrest board 3 for resting the neck, and the neck towing part 7 comprises a slider 72 having a certain length with an end of it being engaged with the backrest board 3, a neck rest part 73 engaged to the other end of the slider 72, a jaw strip 732 engaged at the neck rest part 73 for fixing a user'"'"'s jaw and a tension part 74 which is formed of a body 742 one end of which is engaged to the backrest board 3 and a piston rod 744 engaged to the body 742 and the neck rest part 73, respectively.

10. The apparatus of claim 9, wherein the tension part 4 is formed of a body 742, and a piston rod 744 which is engaged to the body 742 and reciprocates, and the piston rod 744 generates a driving force for disengaging the neck rest part 73 with the aid of a pressurizing means disposed in the interior of the body 742.

11. The apparatus of claim 9, wherein there is provided a length adjusting apparatus 9 for adjusting the length of the neck rest part 73, and the length adjusting apparatus 9 comprises a variable box 92 formed at the base 2 and having a multiply-staged adjusting groove 93, an operation lever 94 which is rotatably engaged to the variable box 92 and is inserted into the adjusting groove 93, a horizontal bar 95 which is integrally connected to the operation lever 94, and a link rod 96 one end of which is connected to the horizontal bar 95, and the other end of which is connected with the neck rest part 73, the link rod 96 being configured to have a certain length.

12. The apparatus of claim 11, wherein the variable box 92 features in that a multiple-stage adjusting groove 93 is formed in a tooth shape, and an operation lever 94 is rotatably engaged in the interior of the variable box 92, and the multiple-stage adjusting groove 93 is configured to increase or decrease the length of the link rod 96 depending on each stage.
