Description

[Detailed description of the device]

[0001]

INVENTION The present invention relates to you on a table or chair, etc.
The end of the kicking horizontal Ashi杆, appearance good, reliable, yet about height adjustment device installed often cheap <br/> constant.

[0002]

Conventionally, in order to facilitate the movement of the tables and chairs, as shown in FIG. 3, the legs of the (01) horizontal Ashi杆(02) was set only <br/> the lower end of the Provide a screw hole on the lower surface of the tip,
A screw hole, and screwing the screw shaft projecting from the upper surface of the caster (03), has been fixed casters (03).

[0003] In order to allow adjusting the height of such a table or a chair, as shown in FIG. 4, in place of the caster taken discoid leg seat (the 04) to the lower surface of Ashi杆(02) May be attached. In this case , attach the height adjustment screw to the top of the leg seat (04).
The shaft is provided, the screw shaft, adjustably be screwed to Rukoto the screw hole of Ashi杆(02).

Further , in order to eliminate the instability of the leg rod when a caster having a size higher than that of the leg seat is attached to the leg rod, an upward notch is provided on the lower surface of the end of the leg rod. on surface of the notch, some of which provided with a threaded bore for attaching the screw shaft in the casters or legs seat. According to this configuration, when the caster is attached to the leg rod, the leg rod is lowered by the height of the notch portion as compared with the conventional case, so that the instability of the leg rod is eliminated.

[0005]

The present invention is to provide a as described above, the leg seat
The screw shaft which definitive when attached to the upper surface of the notch of Ashi杆protrudes to sufficiently lower leg seat from the lower surface of Ashi杆, in order to the floor surface may contact the screw shaft of the leg seat a, shall be lengthened by the height of the cut-out portion.

However, the relatively elongated upper threaded shaft, the attaching screwed into the screw hole of Ashi杆, longer length between the lower surface of the screw insertion part and leg seat, the leg seat not only the mounting state becomes unstable, the screw shaft is easily broken excessive stress on the screw shaft acts.

Further, because Oh is provided a notch in Ashi杆, becomes thinner thickness of Ashi杆the vertical direction in the upper surface of the notch,
Accordingly, also shorter threaded hole formed in the upper surface of the notch. However, height-adjustable width of the leg seat, it is the screw shaft of the leg seat
Since the length that can be screwed into the screw hole, that is , the length of the screw hole, depends on the length of the screw hole, the height adjustment width of the leg seat inevitably becomes smaller when the notch is provided in the leg rod. .

[0008] The present invention has been made in view of such problems, and increasing the height adjustment width of the leg seat, and the length of the screw shaft <br/>, attached and stably legs seat The goal is to be as short as possible .

[0009]

In order to achieve the above object, a height adjusting device for furniture or the like according to the present invention is provided with an end of a horizontal leg rod.
Notch is provided on the lower surface of the part and the notch
A vertical screw hole is provided on the upper surface of the
The receiver was inserted and inserted into the top wall of the receiver from below.
Insert the male screw shaft of the headed bolt into the screw hole to
Use the height adjustment screw holes drilled from the bottom surface to
Insert the installed screw shaft, and further inward from the receiving body.
The protruding support piece was fitted into the receiving groove provided on the leg rod.
Is characterized by.

Further, a height adjusting pad is provided on the lower end surface of the receiving body.
An upward annular groove that is concentric with the hole is provided.
The upward cylindrical wall protruding from the outer circumference of the screw shaft on the upper surface of the leg seat.
And also it is rotating freely fitted.

[0011]

[Action] First, fitting the受支body the notch of Ashi杆 and attach to Ashi杆 by headed bolts. Next, the screw shaft of the leg seat, received
Threaded into height adjustment screw holes in the支体. Thus, Ashiza via 受支body, height adjustably attached to Ashi杆. In this case , since the height of the notch is supplemented by the receiving body , the screw shaft of the leg seat can be made particularly short.
Wear.

Also , in the receiving body that is screwed with the screw shaft of the leg seat,
Since the height adjusting screw hole is sufficiently long, the height adjusting width of the leg seat becomes large .

[0013]

[Embodiment] An embodiment of the present invention will be described below.,Theory based on the drawings
Reveal Figure 1 shows the rod (1)Tip ofTake the casters (2)
It shows the attached state.,Conventional
ThingsIs not substantially different from.IeCastors (2)
Is provided on the lower surface of the end of the leg rod (1).UpwardIn the notch (3)
Partially fittedEntered,Notch (3)UpProvided on the surfaceVertical
HoleTo (4),Castors (2)Screw shaft protruding upward from
Screw (5)I am doing it.

According to this structure, the leg rod (1) is lowered by the height of the notch (3) even when the casters (2) are attached, so that the stability of the leg rod (1), and by extension, the table. Alternatively, the stability of the chair or the like will be improved.

FIG. 2 shows a state in which the leg seat (6) is attached to the leg rod (1) according to the present invention. Each configuration will be described in relation to the mounting process.

[0016] First, an upward notch (3) at the end of Ashi杆(1), to enter fitting the Ashitangu (7). Upper part of the leg end tool (7)
Of the through hole formed in the top wall of the chromatic top tubular受支body (8), from below the headed bolt (10) to insert City, the externally threaded shaft (9),
By screwing the Taneji provided in the upper surface of the notch (3) holes (4), fixed 受支body (8) to Ashi杆(1). in this case,
Screw holes (4) to threadedly interpolated headed bolt (10) appearance is good since it does not exposed to the outside.

It should be noted that the receiving member (8) has a horizontal inward direction.
Rutotomoni provided piece (11), receiving grooves the upright support member (12) to the inner end of the horizontal plate (11), the support piece (12), are drilled into the notch (3) the Rukoto is fitted on (13),受支body (8)
Is locked .

Next, the leg seat (6) is attached to the lower surface of the support body (8 ) so that its height can be adjusted. This screw shaft was <br/> erected from the upper surface of the leg seat (6) to (14), a height which is engraved on the lower surface of the受支body (8)
This is done by screwing it into the adjusting screw hole (15). In this case , the length of the screw hole (15) can be made relatively long corresponding to the height of the support body (8), so that a sufficient height adjustment width is secured.

[0019] Incidentally, the lower surface of the受支body (8), screw holes (15) and only set an upward annular groove (16) forming a concentric Rutotomoni leg seat
A cylindrical wall (17) is projected on the outer periphery of the screw shaft (14) on the upper surface of (6) and screwed.
At the same time as screwing the shaft (14), insert the cylindrical wall (17) into the annular groove (16) .
If it is fitted so that it can rotate without any gap , the leg seat (6)
The screw shaft (14) of is not exposed to the outside, not only the appearance is good,
Hair, dust and the like on the floor will not be caught between the screw shaft (14) and the height screw hole (15) , so that the height can be adjusted smoothly without any trouble.

Furthermore, the bottom surface of the leg seat (6), if Shiagere to <br/> spherical as illustrated, and a large load acts on Ashi杆(1), the leg seat (6) floor Even when it is strongly pressed against the surface, the leg seat (6) for height adjustment can be easily rotated with a small force.

[0021]

According to the present invention, there is a receiver.
Because, rather than need to be particularly long the screw shaft of the leg seat, leg seat is mounted and stable and there is no worry that the screw shaft is broken. Also <br/>, the screw holes受支body threaded shaft of the leg seat is screwed, correspondingly to the height of the leg end device, it is possible to sufficiently long,
The height adjustment width of the leg seat can be increased.
