[0003]

However, a large tilting force is applied to this type of adjuster device when moving furniture or the like. Therefore, in order to secure a certain level of strength, each adjuster base must be securely attached to the furniture bottom surface by a plurality of bolts. Under such circumstances, the conventional adjuster device has a problem that the number of parts is large and a great number of man-hours are required for assembly. As another device, there is a device in which the bottom surface of furniture is directly processed with a nut, or a nut is directly welded, and an adjuster body is screwed to the nut portion. However, it is difficult to directly perform fine processing on the bottom surface of bulky furniture, and there is a problem that the manufacturing line is complicated. Further, in this case, when the furniture main body is painted, the paint easily enters the female thread portion of the nut, which makes it difficult to screw the adjuster main body.

An object of the present invention is to eliminate such problems.

[0005]

The present invention takes the following means in order to achieve such an object. That is, the adjuster device in the furniture according to the present invention, in which the adjuster base is attached to the bottom of the furniture, and the adjuster main body having the grounding portion is held in the adjuster base in a vertically adjustable manner, in the bottom of the furniture, A recess opening downward is provided, and a fitting portion for non-rotatably fitting to the recess is provided on the adjuster base, and elastic deformation of the member is used between the fitting portion and the recess. It is characterized in that a concave-convex engaging portion for preventing engagement is provided.

The frame portion 21g includes the adjuster base 21 and the recess portion 22,
When fitted to 24, the opening window 22b of their recesses 22 and 24, Yes so as to exposed to the outside through the 24b, also the protruding portion 21f ₂ is adjuster base 21
When fitted into the recesses 22 and 24, they are pressed against the inner edges of the opening windows 22b and 24b, and the hinge portions 21f ₁
The dimensional relationship is such that it can be folded inward around the fulcrum. Further, when the fitting portion 21a is completely housed in the recesses 22 and 24 (see phantom lines in FIGS. 2, 3, 8, and 9), the protruding portion 21f ₂ faces the opening windows 22b and 24b. It is set so that it can be positioned in the part.

Further, as shown in FIG. 16, the adjuster body 23 includes a grounding portion 23a made of resin or the like having a large friction coefficient with the floor surface, and a hexagonal nut-shaped spanner engaging member provided above the grounding portion 23a. The joint portion 23b and the shaft portion 23c projecting upward from the spanner engaging portion 23b are provided, and the shaft portion 23c can be inserted into and retracted from the embedded nut member 21d of the adjuster base 21. So that it can be done.

However, when the adjuster device is mounted, the adjuster base 21 is inserted into the recesses 22 and 24.
The fitting portion 21a is pressed in or placed. At this time, the fitting portion 21a is gradually and deeply inserted into the recesses 22 and 24 with the elastic bent portion 21f being folded. When the projecting portion 21f ₂ comes to a portion facing the opening windows 22b, 24b (see imaginary lines in FIGS. 2, 3, 8, and 9), the elastic bending portion 21f is pressed from the recesses 22, 24. The force is canceled, and the bent portion 21f performs an elastic restoring operation with the hinge portion 21f ₁ as a fulcrum. Then, the projecting portion 21f ₂ is projected into the opening windows 22b and 24b. At this time, the concave and convex engaging portions 25 and 26 are formed between the elastic bent portion 21f and the opening windows 22b and 24b, respectively. In this state, however, the lower surface of the protruding portion 21f ₂ contacts the connecting plate 14b or the cut-and-raised piece 24c, and the recesses 22 and 2 of the fitting portion 21a are contacted.
4 is prevented from falling off, and the fitting portion 21a is held by the recesses 22 and 24 so as not to turn. After the adjuster base 21 is attached in this manner, the adjuster main body 2 is attached to the embedded nut member 21d of the adjuster base 21.
When the shaft portion 23c of No. 3 is screwed and screwed to an appropriate position while adjusting the vertical position, the grounding portion 23a is grounded to the floor surface to complete the work. In addition, the shaft portion 23c of the adjuster main body 23 is embedded in the embedded nut member 21d of the adjuster base 21.
It is screwed in advance to the adjuster base 21 in that state.
Of course, the recesses 22 and 24 may be mounted.

With the above arrangement, the adjuster base 21 can be attached to the recesses 22 and 24 with a one-touch feeling, and moreover, the fitting portion 21a is provided with the recess 2.
Since the fitting and holding of the adjuster base 21 in the recesses 2 and 24 is made impossible, the rattling of the adjuster base 21 in the recesses 22 and 24 and the dropping of the adjuster base 21 from the recesses 22 and 24 are reliably prevented.
Sufficient strength is exerted even when a large tilting force is applied when moving. Therefore, when the adjuster device of this embodiment is applied, the number of parts and the number of assembling steps are reduced as compared with the conventional case where the adjuster base is attached to the bottom of the desk by using a plurality of bolts. Excellent effect is achieved. Moreover, when a tilting force is applied to the adjuster base 21, the outer surface of the frame portion 21g abuts the inner edges of the opening windows 22b and 24b of the recesses 22 and 24 and receives the tilting force, so that the elastic bending portion 21f is tilted. It is possible to effectively prevent the elastic bent portion 21f from being broken by not directly applying force. Such a configuration is particularly effective in the recess 24 on the rear end side that is not surrounded by walls on four sides. Further, since it is not necessary to perform fine thread cutting or welding on the bottom of bulky furniture, the production line is not complicated. Moreover, since the adjuster device can be assembled after the furniture is painted, there is no problem that the paint is attached to the screw holes and it takes time to screw the adjuster body.

The specific construction of each part including the cross-sectional shape of the recess and the fitting part is not limited to the illustrated example, and various modifications can be made without departing from the spirit of the present invention. .

[0015]

As described above in detail, according to the present invention, the adjuster device comprises the concave portion on the furniture main body side and the fitting portion on the adjuster base side that is fitted into the concave portion so as not to be rotatable. When the mating part is fitted in the recess, the concave-convex engaging part is formed by utilizing the elastic deformation of the members between the two parts, so the adjuster base can be operated with one touch without using bolts or the like on the bottom of the furniture body. Despite being able to wear it,
It is possible to prevent the adjuster base from rattling or falling off, and to effectively support the falling force acting on the adjuster base. Therefore, there is an excellent effect that the number of parts can be reduced and the man-hour required for manufacturing and assembling can be reasonably reduced without impairing the strength as an adjuster.
