Description

[Detailed description of the invention] [Field of industrial application] This invention supports electrical equipment such as televisions and audio equipment products, and supported objects such as furniture, and also absorbs vibrations from floors etc. The present invention relates to a leg structure that functions as a cushioning material for a supported body.

[Conventional technology]

Conventionally, this type of leg structure has been proposed in Japanese Utility Model Application Laid-Open No. 51-52749 as shown in FIG. That is, in the drawing, A is an inverted bowl-shaped leg body made of a flexible material such as rubber and having a required height, and the leg body A has upper and lower through holes B in its center. , is provided with a locking protrusion (flange) C on the inner periphery of its upper end opening. D is a pin body that can be inserted into the through hole B, and has a flange-shaped head E at one end and a locking pawl F on the outer peripheral surface of the shaft portion. G is a piece of furniture to which the legs A mentioned above are attached, and a mounting hole H is opened in the lower surface of the furniture.

Therefore, after the leg body A is brought into contact with the lower surface of the furniture G, the pin body D is press-fitted into the mounting hole H of the furniture G from the lower end opening of the through hole B of the leg body A. The legs A are fixed to the lower surface of the furniture G by locking the locking claws F on the peripheral surface.

FIG. 5 shows another conventional example disclosed in Japanese Utility Model Publication No. 1288/1988, which includes a leg body A having a predetermined height and defining a through hole B inside, and an upper surface of the leg body A. A rivet body C that is more protruding, an insertion hole D that is bored in the axial direction inside the rivet body C, and a hole D that is driven into the insertion hole D to make the free end of the rivet body C radially The rivet body C and the drive pin E have their axes aligned and are integrated in advance by a fragile connecting portion F. G is a member to be attached, such as furniture, and is a leg of the furniture having a structure in which an attachment hole H is formed in the floorboard thereof.

Therefore, first, the rivet C of the leg A is inserted into the mounting hole H of the member G to be attached, and the upper surface of the leg A is brought into contact with the floor plate of the member G to be attached. Next, the stud body C
When the drive pin E is driven into the inner insertion hole D, the tip of the drive pin E hits the tapered inner surface of the rivet body C due to the breakage of the fragile connecting part F, and the rivet body C is radially moved from the inside. The leg body A is fixed to the member G to be attached by expanding its diameter so that its outer surface comes into pressure contact with the inner wall surface of the attachment hole H.

[Problem that the invention attempts to solve]

By the way, the legs of this type of furniture are required to be made of a soft material that will not damage the floor surface, and, contrary to this, they must be made of a material that is sufficiently soft to support the load of the furniture. It must have structural strength in the vertical direction, and in the case of relatively heavy furniture, it must have structural strength that will not deform even under horizontal loads when a vertical load is applied to move it while sliding on the floor. It is important to be prepared.

Therefore, in the above conventional example, in order to prevent damage to the floor surface and to function as a buffer member, each of the legs A has a double wall structure inside and outside with a space in the middle. In, Jikko 60-1288
The structure in the publication has reinforcing ribs interposed between the inner and outer double walls.

As a result, even if the legs A are made of a relatively soft material, they can withstand vertical loads. However, the structural strength against horizontal loads seems to be insufficient. In other words, if the furniture is subjected to a vertical load and is allowed to slide sideways, there is a risk that the legs A may be crushed horizontally, and the pins have short and long tack bodies. Since the structure is such that the leg A is held in place, it gradually loosens due to the elastic deformation of the leg body A as described above, and there is a problem that the leg body A may escape from the leg body A.

[Means for solving problems]

The present invention was developed to solve the above-mentioned conventional problems, and even when made of relatively soft material, it can withstand not only vertical loads but also horizontal loads. The purpose of this is to provide a device that can be used in a variety of ways, and the pins will not escape.The gist of this is to provide a flange portion that comes into contact with the floor on the lower surface of the main body, which is formed in the shape of a truncated hollow cone. An auxiliary rivet body is suspended from the lower surface of the center part, and a rivet body is protruded from the upper surface to be inserted into the mounting hole of the supported body, so that the rivet body and the auxiliary rivet body are connected to each other. A blind insertion hole into which a pin is inserted from the lower end is bored in the axis of the tack body, and vertical grooves are radially provided in the tip of the tack barrel to communicate with the top surface of the insertion hole. The leg structure of the supported body is characterized in that a locking piece that is pushed outwardly is formed, and a protrusion that is pressed against the outer circumferential surface of the pin is formed on the inner circumferential surface of the insertion hole. be.

〔Example〕

Hereinafter, the present invention will be explained in detail based on the embodiments shown in the drawings. Note that FIG. 1 is an exploded perspective view of the leg structure according to the present invention, and FIG. 2 is a partially cut away side view of the leg structure in use.

In the drawing, reference numeral 1 denotes a leg body having a predetermined height made of a soft material such as synthetic rubber or synthetic resin, which is hollow inside and shaped like a truncated cone with a predetermined wall thickness. A main body part 2, a flange part 3 connected to the outer peripheral edge of the lower surface of the main body part 2, and a main body part 1.
It consists of a rivet body 4 that is bored from the center of the upper surface, and an auxiliary rivet body 5 that is formed to hang down from the center of the lower surface of the main body 2.

An insertion hole 6 of the same diameter is formed near the tip of the rivet body 4 at the axis of the rivet body 4 and the auxiliary rivet body 5. A plurality of (four in the drawings) locking pieces 8 are formed by forming vertical grooves 7 radially that communicate with the top surface 6a of the insertion hole 6. Further, a tightening protrusion 9 is formed in a ring shape on the inner peripheral surface of the auxiliary tack body 5.

Reference numeral 10 denotes a pin that can be freely inserted into the insertion hole 6. The outer diameter of this pin 10 is suitable for the insertion hole 6, and its tip is formed into a semicircular shape. A disc-shaped head 11 is formed at the base of the disc.

Reference numeral 12 denotes an object to be supported such as electrical equipment or furniture, and a mounting hole 13 is formed in the floor plate 12a, and the inner diameter of this mounting hole 13 is formed to be approximately the same as the outer diameter of the stud body 4. .

[Effect of the embodiment]

First, the stud body 4 of the leg 1 is inserted into the mounting hole 13 of the supported object 12, and the upper surface of the main body 2 is brought into contact with the floor surface 12a of the supported object 12.

Next, when the pin 10 is driven into the insertion hole 6 from the lower side of the auxiliary tack body 5, the semicircular portion at the tip protrudes from the top surface 6a of the insertion hole 6, so that each locking piece 8 , are pushed outward with the circumference of the mounting hole 13 of the supported body 12 as a boundary.

As a result, the leg body 1 is attached to the floor surface 12a of the supported body 12.
The supported body 12 is firmly fixed to the leg body 1.
is held on the floor 14 by. At this time, the main body 2
Since it is formed in the shape of a truncated hollow cone, it has a high retention strength against vertical forces even if it is thinner than a flat plate, and the flange part remains stable even when a horizontal load is applied. 3 slides on the floor 14,
It will not be crushed and deformed.

The pin 10 also includes a rivet body 4 and an auxiliary rivet body 5 that is formed to hang down from the center of the lower surface of the main body 2.
The holding force of the pin 10 in the insertion hole 6 is strengthened because the pin 10 is held in the relatively long insertion hole 6 formed by the pin 10 and is in circumferential contact with the ring-shaped tightening protrusion 9. Even when a horizontal load is applied to the leg 1, the pin 10 does not escape from the insertion hole 6.

FIG. 3 is a longitudinal sectional view showing the main parts of another embodiment,
In the above embodiment, the protrusions 9 formed in the auxiliary tack body 5 were formed in a ring shape, but in this embodiment, they are formed in a semispherical shape, and are dotted around the circumference. There is. Other points are similar to the above embodiments.

[Effect of idea]

As described above, the leg structure of the supported object according to the present invention includes a flange portion that comes into contact with the floor on the lower surface of the main body formed in the shape of a truncated hollow cone, and auxiliary rivets on the lower surface of the central portion. While the body is hanging down, a stud body is protruded from the upper surface to be inserted into the mounting hole of the supported object, and a pin is inserted from the lower end into the axis of the stud body and the auxiliary stud body. A shaped insertion hole is bored, and a vertical cut groove communicating with the top surface of the insertion hole is radially provided at the tip of the tack body to form a locking piece that is pushed outward by the pin. In this case, since the inner peripheral surface of the insertion hole has a protrusion that is pressed against the outer peripheral surface of the pin, the structure has a high structural strength against vertical and horizontal loads, and the pin can be inserted into the insertion hole. Since there is no chance of accidental escape, there are various effects such as improved durability.
