[Detailed description of the invention]

[0001]

The present invention can be used by screwing it on various equipment, legs of a desk, a chair, etc., and by screwing it, it can be used for various objects such as the above equipment. ,
The present invention relates to improvement of an adjuster suitable for freely adjusting the level and the like.

[0002]

2. Description of the Related Art Many conventional examples of this kind can be already seen, but in the first conventional example shown in FIG. 4, only one end of a shaft screw a is provided. The seat base d having the lower end opening c is integrally attached to the base base b, and the base body b is provided on the bottom surface b 'of the base base b. A negative locking groove e is provided at the lower end opening c.

[0003] Therefore, when using the above, the shaft screw a
And the seat body d are integrally formed, so that when this is screwed to a leg of a desk or the like, it can be quickly mounted by using a power tool or the like utilizing the locking groove e. Although it is possible, during actual use, the seat d is pressed and supported on the floor, so unless the force is considerably large, the seat d cannot be rotated to adjust the height of the desk or the like, and When it is difficult to move, the level cannot be adjusted unless the desk is lifted.

Next, according to the second conventional example shown in FIG. 5, a screwing corner a1 is provided on the base end side of the shaft screw rod a, and a connecting shaft a2 is projected from the shaft center thereof. The cover f and the seat d are sequentially fitted, and at this time, an E-ring g is engaged with the distal end of the connecting shaft a2 protruding from the seat d so that the shaft screw a is connected to the cover f. With respect to the shaft a2, the end surface a 'of the shaft screw a is fixed to +
Alternatively, a negative locking groove e is engraved.

As a result, according to the second conventional example, since the connecting shaft rod a2 is prevented from falling off by the E-ring g, the lower end opening c of the seat body d is set to the position shown in FIG. After the E-ring g is dropped into the eccentric space c1 in the lower end opening c, it is laterally moved so as to engage with the connecting rod a2. No. Therefore, not only the compressive strength of the seat body d that is pressed and supported on the floor is reduced due to the presence of the thin portion d1, but also by using the E-ring g, the tension between the seat body d and the shaft screw a is reduced. The strength in the direction is also very weak.

The above-mentioned deficiencies become more remarkable when a so-called swing type adjuster is manufactured. That is, in this case, it is possible to swing in the direction of the arrow h in FIG.
Even if the seat body d is supported on an inclined floor or the like, the shaft screw rod a can maintain the vertical standing state. In this case, of course, the E-ring g and the A gap must be formed between the lower end opening c and the top surface c '. In such a case, the E-ring g is particularly likely to come off.

According to the second conventional example, the screwing corner portion is certainly different from the first conventional example even when the seat d protruding downward from the cover f is placed on the floor surface. By using the a1 and the screwing tool, only the screwed rod a can be rotated while the seat body d is stationary, so that the level of the desk or the like can be easily adjusted. There is a weak point in strength associated with the above.

A third conventional example as shown in FIG. 6 is also known. In this case, a swinging type is shown, and a base a3 for continuous attachment is provided on the base end side of the shaft screw a. The cover f is integrally fixed thereto, and the seat body d is fitted onto the connecting rod a2 protruding from the continuous mounting base a3 as in the case of FIG. The caulking head a4 is bulged at the lower end of the connecting rod a2 extending from the seat body d, so as to be in the retaining state as described above.

Therefore, according to the third conventional example,
Under the use condition of the adjuster, the shaft screw a can be rotated by rotating the cover f, and the level adjustment can be easily performed even by manual operation or the like, and the caulking head a4 is formed. Although the strength can be sufficiently maintained as compared with the second conventional example, since the caulking head a4 is used, a + or-locking groove or a square hole cannot be formed on the head a4. When the adjuster is first screwed on a desk leg or the like, the work cannot be efficiently performed using a power tool or the like.

[0010]

SUMMARY OF THE INVENTION The present invention has been studied in order to solve the difficulties which cannot be avoided by the above-mentioned various conventional examples, and corresponds to the connecting shaft of the shaft screw in the third conventional example. In the place to be formed, a cylindrical portion for continuous mounting is formed instead of a cylindrical one, and the end of the cylindrical portion for continuous mounting is bent toward the outer peripheral side to form a caulking peripheral portion, whereby the shaft screw is sufficiently rotated. In addition to being connected to the seat body with high strength, a screwing locking portion such as the above-mentioned + or-locking groove or polygonal locking hole is provided in advance in the inner part of the above-mentioned connecting cylindrical portion. It is an object of the present invention to efficiently mount an object to be mounted on a desk or the like using a power tool or the like using the device.
