Abstract

A sliding stop switch may include a first rod extending in the longitudinal direction thereof, a second rod coupled to the first rod such that one end portion thereof is slidable in the longitudinal direction of the first rod, and a switch member coupled to the first rod to slide in the longitudinal direction of the first rod and to be fixed at a plurality of points on the first rod to stop the sliding of one end portion of the second rod.

First claim

What is claimed is:

1. A sliding stop switch apparatus comprising:
a first rod extending in a longitudinal direction thereof;
a second rod slidably coupled to the first rod such that a first end portion of the second rod is slidable in the longitudinal direction of the first rod; and
a switch member slidably coupled to the first rod to slide in the longitudinal direction of the first rod and configured to be selectively fixed at at least one of a plurality of points on the first rod to stop sliding of the first end portion of the second rod in the first rod,
wherein the switch member is provided at a side thereof with a coupling protrusion formed protrudingly toward the first rod, and the first rod is provided at the plurality of points with coupling recesses such that, when the coupling protrusion is inserted into at least one of the coupling recesses, the switch member is fixed to the first rod, whereby sliding of the switch member is stopped by the coupling protrusion, and
wherein, at each position of the switch member at which the coupling protrusion on the switch member is inserted into one of the coupling recesses in the first rod, the switch member and the first rod are respectively provided with a first magnet and a second magnet, which face each other to attract each other.

2. The sliding stop switch apparatus according to claim 1 , wherein the first rod is located on the second rod or the switch member to surround opposite side surfaces and a portion of a lower surface of the second rod or the switch member.

3. The sliding stop switch apparatus according to claim 1 ,
wherein the coupling protrusion is formed of a plurality of coupling protrusions and the coupling recesses are formed in a direction perpendicular to a sliding direction of the switch member.

4. The sliding stop switch apparatus according to claim 1 ,
wherein the switch member is provided at positions thereof spaced from the coupling protrusion with a plurality of first magnets, which are mounted in a sliding direction of the switch member or a direction perpendicular to the sliding direction of the switch member, and
wherein the first rod is provided at positions thereof corresponding to the plurality of first magnets, which are provided at the plurality of points of the switch member at which the coupling protrusion on the switch member is inserted into each of the coupling recesses in the first rod, with a plurality of second magnets, which are mounted to face the respective first magnets provided at the switch member to attract each other.

5. The sliding stop switch apparatus according to claim 1 ,
wherein the switch member includes a body portion, on which the coupling protrusion is formed, and a rotation member pivotally coupled to the body portion in a receiving hole formed in the body portion of the switch member, the rotation member having a first bearing mounted at a first end portion of the rotation member, and
wherein, when the rotation member is rotated relative to the body portion, the first bearing is exposed in a direction in which the coupling protrusion protrudes, whereby the coupling protrusion is separated from a corresponding one of the coupling recesses.

6. The sliding stop switch apparatus according to claim 5 ,
wherein a second end portion of the rotation member is exposed through the receiving hole in a direction opposite to the direction in which the coupling protrusion protrudes, and
wherein when the second end portion of the rotation member is rotated relative to the body portion, the first bearing rotates the body portion relative to the first rod while being exposed in the direction in which the coupling protrusion protrudes, whereby the coupling protrusion is separated from the corresponding one of the coupling recesses.

7. The sliding stop switch apparatus according to claim 6 ,
wherein the body portion is provided with a support member protruding in the direction opposite to the direction in which the coupling protrusion protrudes, and the second end portion of the rotation member extends to be disposed through the receiving hole at an oblique angle relative to the support member such that, when the second end portion of the rotation member is pushed toward the support member, the first end portion of the rotation member is rotated relative to the body portion toward the first rod.

8. The sliding stop switch apparatus according to claim 1 ,
wherein the second rod is provided at the first end portion thereof with a second bearing configured to be rotated such that the second rod slides along the first rod.

9. The sliding stop switch apparatus according to claim 8 ,
wherein the second bearing is slidably coupled to a pushing recess formed in the first end portion of the second rod to move in the pushing recess such that the second bearing is exposed out of the second rod toward the first rod or is moved inward the second rod, and
wherein the first end portion of the second rod is provided with an elastic body for pushing the first end portion of the second bearing outward the second rod such that the second bearing is selectively exposed by the elastic body out of the second rod toward the first rod in the pushing recess.

10. The sliding stop switch apparatus according to claim 1 ,
wherein when the sliding of the second rod is stopped, the first end portion of the second rod comes into contact with a side surface of the switch member to be supported thereby.

11. The sliding stop switch apparatus according to claim 1 ,
wherein the first end portion of the second rod is rounded and a side surface of the switch member has a shape that surrounds the first end portion of the second rod.

12. A wearable chair comprising:
the sliding stop switch apparatus according to claim 1 ; and
a third rod having an upper end portion rotatably coupled to an end portion of the first rod, the third rod extending in a longitudinal direction thereof,
wherein the third rod is rotatably coupled to a second end portion of the second rod.

13. The wearable chair according to claim 12 ,
wherein the first rod is configured to be connected to a thigh of a user,
wherein the third rod is configured to be connected to a lower leg of the user, and
wherein a lower end portion of the third rod is configured to contact a ground when the user sits down.

14. The wearable chair according to claim 12 ,
wherein when sliding of the first end portion of the second rod is stopped at a point of the first rod by the switch member, a rotation of the second rod relative to the first rod or the third rod is stopped.
