Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a structure for attaching an adjuster to an attached member such as a support leg of a table or a bookshelf.

(Prior Art) An adjuster made of resin or the like is attached to an end surface of a support leg (an attached member) of a table, a bookshelf, or the like. This is because if the support legs are placed directly on the floor, there is a risk of damaging the floor, so by placing the support legs on the floor via the adjuster, this is to prevent the floor from being scratched. by.

Conventionally, the adjustment structure between the adjuster and the support leg has been such that the adjuster has a male threaded part and the support leg has a female threaded part, and the adjuster can be attached by screwing the male threaded part of the adjuster into the female threaded part of the support leg. It was structured so that it was attached to support legs. However, this mounting structure has a problem in that the adjuster screwed into the female thread of the support leg loosens and falls out from the support leg during transportation.

Therefore, the so-called lock nut method was adopted, in which a locking nut is screwed into the male threaded part of the adjuster, and then the male threaded part is screwed into the female threaded part of the support leg, but even with this, satisfactory results were not obtained. Nakatsuta. Moreover, this arrangement has the disadvantage that it becomes difficult to install the adjuster.

(Purpose of the invention) In order to solve the above-mentioned problems, the present invention provides a mounting structure between an adjuster and a member to which it is attached, which prevents the adjuster from loosening and falling off from the member to which it is attached, and which makes it easy to install the adjuster. The purpose is to

(Structure of the device) In the present invention, a male thread is formed on one side of the adjuster and the attached member, and a female thread is formed on the other, and the adjuster is attached to the attached member by screwing these male and female threads together. In the mounting structure of the adjuster and the attached member, the adjuster and the attached member are provided with opposing surfaces facing each other, and a coil spring is compressed between these opposing surfaces so as to surround the center axis of the screw. The adjuster is always biased in the direction away from the attached member by this coil spring, and the adjuster is wound in the opposite direction to the winding direction of the screw. The gist is the mounting structure between the and the mounted member.

(Example) Fig. 1 shows a table using the mounting structure of the adjuster and the attached member according to the present invention, viewed from the front, and Fig. 2 shows an enlarged part of part A of Fig. 1. It is shown cut out.

As seen in these figures, this table is constructed by combining a top plate 1, support legs 2 that support the top plate 1, and a connecting member 3 that connects the support legs 2. The support leg 2 and the connecting member 3 are
Although not shown in the figure, there are four of each. The support leg 2 is composed of a hollow pipe, and a nut 4 is fitted into the tip thereof.
The nut 4 has a female threaded portion 41, and is fixed to the support leg 2 by a method such as welding.

An adjuster 5 is attached to the support leg 2 via a nut 4.
is installed. That is, the support leg 2 serves as a member to which the adjuster 5 is attached. The adjuster 5 includes a small-diameter male screw portion 51 made of metal and a large-diameter head 52 made of resin. The male threaded portion 51 is formed into a right-handed thread. The adjuster 5 is attached to the support leg 2 by screwing the male threaded portion 51 of the adjuster 5 into the female threaded portion 41 of the nut 4 fixed to the support leg 2.

The support leg 2 and the adjuster 5 are provided with opposing surfaces 42 and 53 that face each other, respectively. A coil spring 6 is interposed between these opposing surfaces 42 and 53 so as to surround the central axis of the screw, that is, in the case of this embodiment, the male threaded portion 51 of the adjuster 5. The coil spring 6 is in a compressed state, with one end pressed against the facing surface 53 of the head 52 of the adjuster 5 and the other end against the facing surface 42 of the nut 4.
As a result, the adjuster 5 is always urged away from the nut 4 by the elastic restoring force of the coil spring 6. Therefore, adjuster 5
The threads of the male threaded portion 51 of the nut 4 and the female threaded portion 41 of the nut 4 are strongly engaged with each other, and the frictional force between them is increased, making it difficult for the adjuster 5 to rotate. In other words, the adjuster 5 is less likely to loosen.

The coil spring 6 is wound in the opposite direction to the winding direction of the male threaded portion 51 of the adjuster 5. In the case of this embodiment, since the male threaded portion 51 is a right-handed thread (the female threaded portion 41 of the nut is also a right-handed thread), the nut is wound to the left.

In this mounting structure, the adjuster 5 can be removed from the support leg 2 by rotating the adjuster 5 to the left (in the direction of arrow B in FIG. 2). That is, the left rotation direction is the direction in which the adjuster 5 loosens. As mentioned above, the winding direction of the coil spring 6 is left-handed. In other words, the coil spring 6 is wound downward to the right. Therefore, one end of the coil spring 6 is
It abuts against the facing surface 53 of the head 52 of the adjuster 5 in a direction opposite to the loosening direction of the adjuster 5. As a result, when the adjuster 5 attempts to rotate in the loosening direction, one end of the coil spring 6 acts as a resistance to the rotation of the adjuster. Therefore, this further suppresses loosening of the adjuster 5. When attaching the adjuster 5 to the support leg 2, the adjuster 5 is rotated to the right (in the direction of arrow C in Fig. 2). In this case, one end of the coil spring 6 does not provide rotational resistance to the adjuster. can be rotated smoothly, and the adjuster 5 can be easily attached to the support leg 2 by simply screwing the adjuster 5.

The mounting structure between the adjuster and the mounted member according to the present invention is not limited to the above embodiment. The winding direction of the coil spring is not limited to left-handed winding, but if the threaded portion is left-handed, it will be right-handed. In the embodiment described above, the adjuster was attached to the support leg via a nut having a female thread, but the support leg may have a female thread and the adjuster may be directly attached to the support leg. Further, in the above embodiment, the attached member has a female thread and the adjuster has a male thread, but the attached member may have a male thread and the adjuster may have a female thread. The attachment structure of the adjuster and the attached member according to the present invention may be used for things other than tables, such as bookshelves and lockers without support legs. Note that in the case of a rocker without support legs, the adjuster is directly attached to the bottom plate, etc., so in this case, the bottom plate etc. becomes the member to be attached.

(Effect of the invention) As explained above, the mounting structure of the adjuster and the attached member according to the present invention is such that the adjuster and the attached member are attached by screwing the male thread and the female thread, and the adjuster and the attached member face each other. Opposing surfaces are formed, and a coil spring is interposed in a compressed state between these opposing surfaces so as to surround the center axis of the screw, and the adjuster is always biased in the direction away from the member to which it is attached by the coil spring. ing. Therefore, the frictional force at the threaded portion increases, making it difficult for the adjuster to loosen. Further, in this mounting structure, the winding direction of the coil spring is opposite to the winding direction of the screw, and one end of the coil spring comes into contact with the adjuster in a direction opposite to the loosening direction of the adjuster. . Therefore, rotation of the adjuster in the direction of loosening is suppressed by one end of the coil spring, making it even more difficult for the adjuster to loosen. Therefore, the adjuster does not become loose and fall off from the member to which it is attached. At the same time, if the winding direction of the coil spring is opposite to the winding direction of the screw, one end of the coil spring will not become a resistance to the rotation of the adjuster when the adjuster is attached to the attached member. The adjuster can be rotated smoothly without any trouble. Furthermore, with this mounting structure, the adjuster can be attached to the member to be attached by simply screwing the adjuster, so the attachment work can be simplified.
