Description

[Detailed Description of the Invention] The present invention relates to a floating trochanter attachment device for a movable suspension that can be attached to a suspension device such as a drawer.

As shown in FIGS. 1 and 4, this mobile suspension is a fixed suspension (not shown) with a rectangular cross section in which the vertical plate part 1 and the upper and lower bent parts 2 and 3 are fixed to a drawer container.
The trochanter 4 has a shaft support 4' at the rear end of the upper part.
A trochanter 55, which has a shaft support 5' at the center and rear of the lower part, is removably fitted into the upper and lower bent portions of the fixed suspension. A drawer 8 (
A rail 9 fixed to the side surface of FIG. 4) is slidably held so that the drawer can be opened and closed.

Therefore, in order to simplify the mounting device for the floating rotor 6, which was conventionally constructed by welding a band plate or the like to the vertical plate part 1, and to prevent the generation of metallic noise during use, For example, the seventh
As shown in FIG. 8 and FIG.
A block-shaped fixing part IL1 is provided at both ends of the band plate part 10 having
A synthetic resin holder 12 provided with a holder 12 is engaged with an engaging pin 13 protruding from the back side of the fixing part 11 into a pin hole 14 drilled in the vertical plate part 1, and a convex part 15 on the front surface of the fixing part is fitted into the notch 16 provided in the downward edge plate part 2' of the upper bent part 2, and the fixing part 11 is fitted into the upper bent part 2, and the tongue piece 17 adjacent to the notch 16 is inserted into the bent part 2. The inwardly directed shaft 6' of the floating rotor 6 fitted in the upper bent portion 2 is slidably held in the retaining groove 10' of this retainer 12 by being bent inward. Otherwise, the shape of the holder 12 is complicated, the movable suspension machine itself requires a lot of processing, and installation is also time-consuming.

In some cases, a longitudinal groove is bored in the vertical plate part of the movable suspension, and the support member of the floating trochanter is freely engaged with this groove, but it is difficult to form a groove in the movable suspension. In addition to requiring machining, the grooves have the disadvantage of reducing the strength of the suspension itself.

The present invention has been made in order to eliminate the drawbacks of the conventional device, and as shown in FIG. A synthetic resin holder 20 provided with a fixing block 19 having a stop protrusion 19' is attached to the upper bent portion 2 of the movable suspension.
The band plate part 18 is brought into contact with the inner surface of the vertical plate part 1 of the movable suspension, and the fixed block 19 is brought into contact with the bent part 2.
The locking protrusion 19' is fitted into the groove of the bent part 2.
It is installed by locking into the engagement hole 21 bored in the edge plate part 2' of the
The outer support shaft 6' of the floating rotor 6 is held in the groove 18'.

Since the floating trochanter mounting device of the present invention has the above-described structure, the shape of the holder 20 is extremely simple and manufacturing is easy, and the processing for the movable suspension body is simply done by forming an engagement hole in the edge plate 2'. 21, there is no need to create a longitudinal groove in the vertical plate of the movable suspension, which reduces machining of the main body and prevents a decrease in strength, and the holder can also be fixed. Just by fitting the block 19 into the upper bent portion 2, the locking protrusion 19' is locked into the locking hole 21, so it can be easily and securely installed.
Also, unlike the conventional holder 12, the band plate part 18 is provided outside the trochanter 6 in contact with the inner surface of the vertical plate part 1 of the movable suspension, so that it is restrained by this plate part 1 and rotates during use. It does not bend as the trochanter moves, and has practical effects such as being able to reliably hold the trochanter even if the holder is made of synthetic resin.
