Hereinafter, with reference to the accompanying drawings will be described an embodiment of the fall prevention leg height adjustment device according to the present invention. In this process, the thickness of the lines or the size of components shown in the drawings may be exaggerated for clarity and convenience of description.

In addition, terms to be described later are terms defined in consideration of functions in the present invention, which may vary according to the intention or custom of users or operators. Therefore, definitions of these terms should be made based on the contents throughout the present specification.

1 is a perspective view showing a height adjustment device for preventing a fall according to an embodiment of the present invention, Figure 2 is a bottom perspective view showing a height adjustment device for preventing a fall according to an embodiment of the present invention, Figure 3 An exploded perspective view of a height adjustment device for preventing a fall according to an embodiment of the present invention, Figure 4 is an exploded perspective view of the bottom of the height adjustment device for preventing a fall according to an embodiment of the present invention, Figure 5 is an embodiment of the present invention Fig. 6 is an operation diagram showing an operation state of an elastic actuating unit in the height adjustment device for preventing a fall in the leg height adjustment device for preventing fall according to an example. .

As shown in Figs. 1 to 6, the height adjusting device for preventing a fall according to an embodiment of the present invention includes a fixing member 10, a support foot member 20, a height adjustment member 30, and a slide member 40. ) And an elastic actuating unit 50.

The fixing member 10 is provided on the bottom of the furniture to provide a space in which the support foot member 20 is installed, and is formed in a cylindrical shape.

The support foot member 20 is fitted so as to be hooked to the fixing member 10. The support foot member 20 includes a fastening portion 21 for receiving the fixing member 20 so as to be seatable, and a housing 22 extending below the fastening portion 21 and supported on the ground.

Here, the fastening part 21 has a male thread formed on the circumferential surface so as to be fastened with the height adjustment member 30, and the housing 22 provides a space in which the slide member 40 and the elastic actuating part 50 are installed. .

In addition, the height adjustment member 30 is rotatably fastened to the fastening portion 21 of the support foot member 20 to support the fixing member 10 to adjust the height. At this time, a female thread coupled to a male thread formed on the circumferential surface of the fastening portion 21 is formed on the inner surface of the height adjustment member 30.

That is, when the height adjustment member 30 is rotated by operation by an external force, the fixing member 20 is raised to protrude from the fastening part 21 or lowered to be inserted into the fastening part 21 according to the direction in which the rotation is operated. Perform.

Thereby, since the height of the fixing member 20 can be adjusted through the rotational operation of the height adjustment member 30 while the support foot member 20 is supported on the ground, convenience of use can be improved.

The slide member 40 is provided on the support foot member 20 to be slidably protruding. The slide member 40 is inserted into the housing 22 of the support foot member 20 and is supported by the elastic actuating part 50 so that when the furniture is transferred to the front side, the housing 22 ) To prevent the furniture from falling. At this time, the slide member 40 is formed with a locking hook 41 so as to be caught or released from the elastic locking portion 52d of the elastic actuating unit 50.

In addition, the slide member 40 may be prevented from being separated from the housing 22 by the separation preventing portion 42 when protruding from the housing 22. This separation prevention part 42 is a locking guide recessed in the bottom surface of the housing 22 so that the engaging bolt 42a and the engaging bolt 42a protrudingly coupled to the bottom surface of the slide member 40 are moved to be engaging. It includes a groove part 41b.

In addition, the slide member 40 restricts the slide movement of the slide member 40 at the moment when the coupling bolt 42a is caught in the locking guide groove 42b when protruding from the housing 22 through the elastic actuating part 50, It is possible to prevent the slide member 40 from being separated from the housing 22.

On the other hand, the elastic actuating part 50 elastically protrudes the slide member 40 from the housing 22 of the support foot member 20 so that the slide member 40 contacts the ground when the furniture is turned over and prevents the furniture from falling. Let it.

To this end, the elastic actuating part 50 is provided in the housing 22, and the locking part 51 and the locking part 51 for locking or unlocking the slide member 40 depending on whether or not the furniture is inverted or not are included in the slide member ( It includes an elasticity providing member 52 for providing an elastic force to the slide member 40 so that the slide member 40 protrudes from the housing 22 of the support foot member 20 when unlocking 40).

At this time, the locking part 51 includes a fixing block 51a that is seatably fixed to the housing 22, and an elevation support member that is received in the fixing block 51a and the housing 22 so as to be liftable and pressurized in contact with the ground ( 52b), and an elastic member 51c and a lifting support member 52b provided in the fixing block 51a to elastically protrude the lifting support member 52b from the housing 22 when the lifting support member 52b is not in contact with the ground. ) Is accommodated to be elastically movable and includes an elastic engaging portion 52d that regulates the slide movement of the slide member 40.

That is, when the elastic engaging portion 52d is normally held in a constrained state of the slide member 40, the furniture is inverted to the front and the lifting support member 52b protrudes from the housing 22 by the elastic force of the elastic member 52. The elastic provision member 52 releases the binding force on the slide member 40 so that the slide member 40 protrudes to one side of the housing 22.

Here, the elastic locking portion (52d) is a state in which the locking member (52e) and the locking member (52e) are elastically raised, which is accommodated in the lifting support member (52b) so as to be able to be lifted and is caught or released from the slide member (40) It includes a spring member (52f) elastically supported by the lifting support member (52b) and the locking member (52e) to maintain the.

Accordingly, when the locking member 52e contacts the locking hook 41 provided in the slide member 40 when the slide member 40 protrudes from the housing 22 and is inserted into the housing 22, the spring member 52f ) To pressurize the lifting support member (52b), and the moment the locking hook 41 of the slide member 40 crosses, the lifting support member ( 52b) rises.

In addition, the elastic providing member 52 is provided so as to be elastically wound around the housing 22, and is made of a mainspring spring coupled to the rear end of the slide member 200 so as to be hooked. That is, when the slide member 40 is axially inserted into the housing 22, the elastic providing member 52 releases the end portion while being held and supported by the housing 22, thereby exerting an elastic restoring force.

Accordingly, since the elastic providing member 52 acts as a force to be wound in the loose state, the slide member 40 acts as a force to be pulled out from the initial state inserted into the housing 22 as much as possible.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is only illustrative, and those of ordinary skill in the field to which the technology pertains, various modifications and other equivalent embodiments are possible. I will understand.

Therefore, the true technical protection scope of the present invention should be determined by the claims.
