[Prior art]

 Heretofore, such a desk or chair height adjustment device has been as follows. In the publication No. 66361 "Two-stage computer with height difference" in Taiwan, No. 216503 "Strength elevation adjustment structure of learning desk chair" and No. 283911 "Improved lifting chair" The height is adjusted using a control pin.

[0003]

[Problems to be solved by the invention]

 The technology described in the prior art has the following problems. The structure described in the prior art described above cannot be performed unless two people are involved in the height adjustment work, because one person lifts a desk or chair and the other loosens bolts and control pins. Otherwise, the desks and chairs will fall by their own weight, and the adjustment work is somewhat inconvenient.

[0004] The present invention has been made in view of such problems of the conventional technology, and has as its object to provide the following. A height adjustment device for a desk or chair is provided, and the height of the desk or chair can be freely adjusted by this structure.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is as follows. That is, the device of the present invention is composed of a bottom 1, an elevating body 2, a stopping part 3, and a control part 4, and two parallel vertical rails 11 are implanted before and after the bottom 1, and the vertical rail 11 A rod 21 which is suspended in a state corresponding to the lower surface of the elevating body 2 is configured to move up and down, and a pair of ear seats 13 are provided below the front of the front vertical rail 11 of the vertical rails 11. The stop part 3 is rotatably mounted on the seat by a shaft mounting part 14, and the notch groove 15 engraved above the ear seat is configured so that the stop part 31 of the stop part 3 passes therethrough, The rod 21 is configured to be inserted in parallel with the vertical rail 11 to be able to move up and down. The rod 21 is provided with several fixing holes 22, and the fixing hole 22 is provided with a stopper 31 of the stopper component 3. The stop part 3 is pivotally attached to the ear seat 13 by a pivot part 14 so as to be freely rotatable. The component 3 is provided with an elastic part 33, and the stop part 31 is always inserted into the fixing hole 22 by the pressing force of the elastic part 33. This is a height raising / lowering adjusting device for a desk or chair that is rotatably mounted and configured to be able to be simultaneously pushed and released with respect to a pair of stop parts 3.

In this case, the following configuration can be adopted. First. The connecting part 41 is configured to be movable by a lateral groove rail 16 provided on the vertical rail 11. Second. The control part 5 is constituted by a long rod, and both ends of the rod are pivotally mounted on the vertical rail 11 so that the control part 5 can simultaneously push the two stop parts 3. Configure. Third. By providing the resilient component 33 on the control component 4, the control component 4 does not need to press the stop component 3 in a normal state.

[0007]

[Embodiment of the invention]

 Embodiments will be described with reference to the drawings. With reference to FIGS. 1 and 2, the present invention is composed of components such as a base 1, a lifting / lowering body 2, a stop component 3, and a control component 4.

The bottom 1 is formed as a leg of a desk or chair standing on the floor, and two parallel vertical rails 11 are planted before and after the bottom 1, and the vertical rail 11 is The rod 21 which is hung in a state corresponding to the lower surface is configured to move up and down. In this case, a sealing member 12 such as a stopper can be provided on the upper part of the rod 21 so that the rod 21 does not escape from the vertical rail 11. A pair of ear seats 13 is provided below the front surface of the vertical rail 11, and the stopper component 3 is pivotally mounted on the ear seat 13 by a shaft mounting component 14. The notch groove 15 is formed, and the notch groove 15 is made to pass through the stop part 31 of the stopper part 3, and the stop part 31 is configured to be inserted into the fixing hole 22 of the elevating body 2. I have.

The elevating body 2 is formed on a tabletop of a desk or a seat surface of a chair, and two rods 21 are hung on the left and right sides of the lower surface of the elevating body 2, respectively. It is configured to be able to go up and down according to. The rod 21 is provided with several fixing holes 22, and the fixing holes 22 are aligned with the cutout grooves 15 provided on the vertical rail 11, and the stopper 31 of the stopper component 3 is inserted into the fixing holes 22. It is configured to be able to.

The stop part 3 is rotatably mounted on the ear seat 13 by a shaft mount part 14 penetrating into a shaft hole 32, and a stop part 31 is provided at one end of the stop part 3. It can be inserted into the fixing hole 22 of the elevating body 2 through the notch groove 15. By pressing the lower part of the stop part 3, the stop part 3 can be pulled out from the fixing hole 22. Further, the stop part 3 is provided with an elastic part 33, and the pressing part of the elastic part 33 causes the stop part 31 to be always inserted into the fixing hole 22, and one end of the elastic part 33 supports the vertical rail 11, The other end is configured to support the stop component 3. For this reason, since the stopping portion 31 always has a force to be inserted into the fixing hole 22 (as shown in FIGS. 3 and 5), it is possible to prevent the elevating body 2 from descending.

The control component 4 is rotatably attached to the front and left of the connecting component 41 so as to be able to push and release the connecting component 41 in the front-rear direction with respect to the stopper component 3. I have. That is, it is configured to be able to move in the front-rear direction within the horizontal groove rail 16 attached to the vertical rail 11. The connecting part 41 can separate the control part 4 from the stop part 3 in a normal state (as shown in FIGS. 3 and 5), and also pushes the control part 4 by an external force to form a pair of stop parts. By pressing the parts 3 simultaneously (as shown in FIGS. 6 and 7), the locking part 31 can be disengaged from the fixing hole 22.

As shown in FIGS. 3 and 5, since the stopping part 31 of the stopping part 3 of the present invention is always inserted into the fixing hole 22 of the elevating body 2 in a normal state, the elevating body 2 can be raised and lowered. It is not possible to fix it at an appropriate height.

As shown in FIGS. 6 and 7, when it is necessary to adjust the height of the lifting / lowering body 2, the lifting / lowering body 2 is slightly lifted with both hands, and at the same time, the control is performed by pushing the connecting part 41 with the leg or the knee. By moving the component 4 inward and pressing the stop component 3, the stopping portion 31 is detached from the fixing hole 22, and the height of the elevating body 2 is easily adjusted. When the pressing force on the connecting part 41 is stopped, the stopping part 3 receives the elasticity of the elastic part 33 and returns to the original position, so that the stopping part 31 is inserted into the fixing hole 22 of the elevating body and fixed. It is configured to be.

FIG. 8 shows a height adjustment device for a desk or chair according to another embodiment. The control component 5 is constituted by a single rod, and both ends of the rod are rotatably mounted at appropriate positions on the vertical rail 11. As described above, since the control component 5 can operate the pair of stop components 3 simultaneously by utilizing the state of being in contact with the pair of stop components 3, the height of the elevating body 2 can be easily adjusted. Is formed. The control component 5 can be provided with an elastic component 33 for slightly pressing the stop component 3 and for preventing the control component 5 from stopping and pressing the stop component 3. As described above, since the pair of stoppers 3 can be simultaneously operated by utilizing the pressing of the control component 5, the height of the elevating body 2 is formed so as to be easily adjusted.
