Description

[Detailed Description of the Invention] This invention relates to a foot for a housing having a structure for extracting and holding a connecting shaft for connecting and fixing two housings in a stacked structure of two housings each having a foot and a foot rest.

Figure 1 shows a cross-sectional view from the front of the fitted state of the conventional feet and the foot rest when two housings are stacked, and Figure 2 shows the two housings with the conventional feet of Figure 1. FIG. 3 is an external structural diagram showing a state in which the bodies are stacked.

In these figures, the legs 3 are screwed to the lower frame 2 near the four corners of the bottom surface 1a of the casing 1, and the legs 3 are screwed to the upper frame 5 near the four corners of the flat surface 4a of the casing 4. The foot rest 6 is screwed so as to face the foot.

The foot 3 has a cylindrical shape and has a fitting hole 7 in the bottom surface thereof into which a foot rest 6 is fitted.

The connecting shaft 8 is bent into a U-shape, and one end 8a is inserted into a through hole 9 provided in the side surface of the leg 3 through the fitting hole 7.

The other end 8b is inserted into a mounting hole 10 provided in the leg 3 parallel to the through hole 9 and avoiding the fitting hole 7.
It is provided with a caulked release stop washer 11 and a helical spring 12.

The footrest 6 has a truncated cone shape, and a connecting shaft 8 is attached to the side surface of the footrest 6.
A positioning hole 13 with a diameter slightly larger than the outer diameter of the foot 3 is provided.
After fitting the coupling shaft 8 into the fitting hole 7 of the helical spring 1
2 and insert it into the positioning hole 13 to connect and fix the leg 3 and the leg holder 6.

However, with this conventional structure for pulling out and holding the connecting shaft, even if you try to pull out the connecting shaft when unfastening the connection between the foot and the foot rest, it is difficult to grasp the connecting shaft, and only your fingertips are applied, so you do not have to apply any force. I had a hard time extracting it.

In addition, the connecting shaft could not be held in its extracted state, and the connecting shaft could not be held in its extracted position unless it was rotated an additional 90' after being pulled out.

This idea was made in view of the above-mentioned problems, and it moves the connecting shaft in the extraction direction until it engages with the connecting shaft and releases the connection fixation, and also moves the connecting shaft relative to the extraction direction. To provide a foot for a casing, which is equipped with a handle member movable so as to be displaced in a right angle direction, allows a connecting shaft to be held while being pulled out with a simple operation, and has an easy-to-grasp structure.

This idea will be explained below.

FIG. 3 shows an embodiment of the foot for the housing according to this invention, and a
b shows its front view, and b shows its side view.

FIG. 4 shows a cross-sectional view taken along the line A-A' in FIG.

FIG. 5 is an external structural diagram showing a stacked state of two casings having casing feet according to this invention.

The foot 20 is D-shaped and includes a mounting portion, a leg portion, a protruding portion, and a handle member.

The mounting portion 20a is fitted into a positioning step portion 24 formed by cutting the outer lower edge of each of the left and right lower frames 23 of the housing 21, 22 into an L-shape along the longitudinal direction thereof.

The leg portions 20b are fitted into foot rests 26 that are formed by cutting the outer upper edges of the left and right upper frames 25 of the housing 21 and 22 to a desired length in an abbreviated shape along the longitudinal direction. Mutual movement of the casings 21.22 in the left-right direction is prevented, and furthermore, both ends 26a of the footrests 26 prevent the casings 21.22 from moving back and forth.

Further, the leg portion 20b has a through hole 28 so as to face the positioning hole 27 provided in the mutually opposing surfaces 26b of the left and right step portions of the foot rest 26 when the foot 20 is fitted into the foot rest 26. There is.

The protrusion 20c provides a gap between the casings 21 and 22 when stacked, and also has a mounting hole 29 parallel to the through hole 28, and is screwed into the connecting shaft 30 bent into a U-shape. One end 30a having a washer 31 and a helical spring 32 is inserted into the mounting hole 29.

The other end 30b of the connecting shaft 30 passes through the through hole 28 and is inserted into the positioning hole 27, thereby connecting the foot 20 and the foot rest 26.

The handle member 20d also serves as a cover to hide structures such as the connecting shaft 30, and is used to move the connecting shaft 30 in the extraction direction until it engages with the connecting shaft 30 and releases the connection fixation. Arm portion 3 having a drive shaft 33
4, and is displaced perpendicularly relative to the connecting shaft 30, that is, moves diagonally upward.

The leg portion 20b has a foot 20 and a footrest 2 as shown in FIG. 4a.
A notch 35 is provided as a relief for the arm 34 when the arms 6 are connected by the connecting shaft 30.

Further, an abutment member 40 having an inclined portion 36.37 and a flat portion 38.39 on the foot 20 and the handle member 20d, respectively.
．． 41 is integrally formed, and the handle member 20d is connected to the drive shaft 3.
3 while being engaged with the connecting shaft 30 through the connecting shaft 30 and moving in the direction in which the connecting shaft 30 is removed from the state shown in FIG. 4a to the state shown in FIG. After that, both contact parts 40 and 41 come into contact with each other,
The connecting shaft 30 is held pulled out against the elasticity of the helical spring 32.

At this time, the size is such that even if the connecting shaft 30 is pulled out until the helical spring 32 is completely contracted, the tip of the end portion 30b will not come out from the through hole 28.

In addition, in the above-mentioned embodiment, the handle member is pulled diagonally upward while being extracted, but the handle member can also be pulled diagonally downward by, for example, reversing the slope of the inclined portion of the contact member. However, it is also structurally easy to pull in the left and right directions.

The sloping portion can function satisfactorily if it is provided on either the leg portion or the handle portion.

Moreover, if the handle member is displaced in any one of the up, down, left, and right directions after being pulled out, the inclined portion is not necessarily required.

Furthermore, although four pairs of contact members are provided in this embodiment, two pairs of contact members are provided.
It can also be a pair or a pair.

In short, various modifications can be made without changing the gist.

As explained above, the handle is movable so as to move the connecting shaft in the extraction direction until it engages with the connecting shaft and releases the connection fixation, and also to displace in a direction perpendicular to the extraction direction of the connecting shaft. Since the connecting shaft is provided with a member and has a structure that abuts against the displaced handle member and holds the connecting shaft in an extracted state against the elastic force of the elastic member, the following effects can be obtained.

(b) The two operations of extracting and holding the connecting shaft can be easily performed by a simple continuous operation of pulling the handle member in the extracting direction and then pulling it so as to displace it in a perpendicular direction relative to the connecting shaft. be able to.

Mouth: The handle is structured to be pulled, so it is easy to use with your fingers and easy to operate.

C. If you want to pull out the connecting shaft and reconnect it while holding it, just flick the handle member with your fingertips.

2. Since the handle member is attached to the outside of the connecting shaft, by using a handle member that also serves as a cover, it is possible to cover the metal structure such as the connecting shaft so that it does not come out.
