Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cradle which is mainly driven and fixed to a load supporting portion such as a leg portion of furniture, and particularly, when it is attached to furniture and used on a floor surface. The present invention relates to a pedestal used for furniture, which has an improved scratch prevention and protection function to prevent scratches such as indentations and drag marks due to furniture load on the flooring surface in recent years.

[0002]

2. Description of the Related Art Generally, a pedestal is attached to a load supporting portion including furniture such as legs of desks, chairs, and various cabinets, and the legs and load supporting portions of furniture come into direct contact with the floor surface. By doing so, it is conventionally used to rub the floor surface so as not to scratch it when moving it, and
It has also been attempted to protect the floor by attaching a protective material such as felt material to the bottom surface of the pedestal.

Further, as a leg holder for furniture, a leg of furniture and a support material of the leg support are connected by a connecting material, and a felt, polyurethane, cloth, wood or the like for floor surface protection is provided on the bottom surface of the support material. Japanese Utility Model Laid-Open No. 63-202342 discloses a structure in which an elastic flat plate material is heat-welded and a convex standing piece for preventing rotation of the connecting member is provided.

[0004]

However, the former protective material formed by sticking a felt material has the drawback that it cannot withstand long-term use and is merely a simple protective means. ing. On the other hand, in the latter case where the floor protector made of elastic flat plate material is used, the friction resistance between the floor surface and the floor protector is too large, so that furniture can be moved smoothly. However, there is a problem in that the smoothness is lost particularly when a load of a person or an object is applied to a chair or a desk.

Moreover, if the floor surface having a step or a groove is moved, the floor surface protection material such as felt, which is heat-bonded directly to the legs of furniture or through the connecting material of the leg support, causes surface contact. This results in peeling, which ultimately leads to the drawback of lacking durability. Therefore, an object of the present invention is to solve the above-mentioned drawbacks of the conventional furniture leg holders, and at the same time, to easily attach the furniture to the load supporting portion, and further to improve the aesthetic appearance after the attachment. The purpose is to provide a cradle used for cost furniture.

[0006]

In view of the above-mentioned object, the present invention forms a smooth convex curved surface toward the contact surface side with the floor surface, and with respect to the load load, the load from the floor surface is applied. Completely integrated by molding and fixing of nail element and synthetic resin material that are easily deformed and buffered by reaction force, and are driven and fixed to the load supporting part of furniture so that they do not peel off or fall off during use. A pedestal for furniture having a pedestal having a coupling structure is configured.

That is, according to the present invention, in a cradle which is driven and fixed to a load supporting portion such as a leg portion of furniture, the cradle has a driving sharp end at an upper end and a substantially bowl-shaped head at a lower end. A driving leg formed on a nail element having
The seat part that is joined and fixed to the head of the driving leg part and is in contact with the floor surface, and the joint part of the driving leg part and the seat part are enveloped and integrated, and the load supporting part of the furniture. And a middle seat portion that forms an upper seat surface that comes into contact with the seat portion. The seat portion is formed of a lump of easily deformable material that deforms and cushions in accordance with a load repulsive force from the floor surface and faces the floor surface. There is provided a cradle used for furniture, which is characterized by having a convex curved surface shape.

In this case, preferably, the seat portion is
The pedestal is made of a compression-fired body of a fluororesin material, and is used as a pedestal used for furniture having a structure in which it is molded and fixed to the head of the driving leg by the synthetic resin material forming the middle seat. Also,
Further, the seat portion is formed by compression-molding a felt material in a mold having a predetermined shape, and has the convex curved surface on the lower surface side and at the same time a concave portion for receiving the head of the driving leg portion on the upper surface side. It may be a pedestal used for furniture which is provided with a hole, and the head of the driving leg portion is cast into the concave hole by the middle seat portion made of a synthetic resin material and fixed integrally.

Preferably, the nail element of the driving leg has a structure having a cedar-like uneven surface in its length direction.

[0010]

With the above structure, the seat portion of the pedestal is
It is composed of a lump of easily deformable material that deforms and cushions according to the load repulsive force from the floor surface and has a convex curved surface shape toward the floor surface, so when furniture is moved under load In addition, since the seat cushions the load reaction force due to the deformation, it does not cause scratches such as indentations or drag marks on the floor surface, and a convex curved surface is formed toward the floor surface side. Since it has no corners, it can function as an assisting means for smoothly moving furniture.

This seat 20 is made of a fluororesin material, that is,
A smooth plate with a well-known material known as polytetrafluoroethylene (PTFE), with its bottom surface 22 facing outward, that is, a smooth convex curved surface that bulges toward the floor to which it comes into contact, or a large rounded corner It is formed as a surface. The seat 20 is made into a resin structure having a desired outer shape by filling a mold such as a mold having a predetermined concave curved surface with a fluororesin powder material and compressing it by applying pressure at room temperature. After that, it is manufactured (free baking method) by heating in a furnace to about 360 ° to 380 °, firing and solidifying, and then gradually cooling to room temperature to complete the sintering. The pedestal 20 sintered and manufactured in this way has elastic deformability, and when it receives a load reaction force from the floor surface, it easily elastically deforms, thereby protecting and preventing damage to the floor surface. By having the proper sliding performance, the furniture can be smoothly slid when the furniture 40 is moved on the floor surface after being mounted on the pedestal 40 and the performance of facilitating the movement of the place can be achieved. You can also do it. Moreover, by having a convex curve shape, the frictional contact area with the floor surface is smaller than that of a simple flat plate surface, so that smooth sliding can be caused.

It should be noted that the driving leg 1 is provided on the upper surface side of the seat 20.
The recessed groove 24 (see FIG. 3) into which the 0 head 14 is fitted is provided in advance in the molding step. On the other hand, the middle seat 30 of the pedestal 40 is made of a synthetic resin material, preferably a well-known ABS resin material, after the head 14 of the driving leg 10 is inserted and positioned in the concave groove 24 of the seat 20.

Then, a synthetic resin material powder such as a powdered ABS resin material is poured, and the intermediate seat 30 is molded by pressurizing and heating it with a male mold (not shown). They are bonded and a strong bond can be obtained.

5 to 7 illustrate a pedestal 40 used for furniture according to another embodiment of the present invention. This pedestal 40
Is composed of a driving leg portion 10A, a receiving seat 20A, and an intermediate seat 30A. The driving leg 10A is a nail element made of a metal material such as an iron material, the tip of which is formed at a pointed end 12a, and a head 14a is provided on the lower portion opposite to the pointed end 12a. The head 14a may have the same structure as the head 14 in the driving leg 10 of the pedestal 40 described above. In addition, in the shaft portion between the sharp end 12a and the head 14a, several mountain teeth 16a extending in the axial direction of the nail are formed to firmly bite into the inside of the leg material when driven into the bottom of a furniture or the like, It is formed to have a retaining function and a retaining function.

As a feature of this embodiment, when the pedestal 40 is fixed to the bottom of a leg or a load supporting member of furniture and the furniture is installed on a floor or a plastic floor, In order to prevent dents, scratches, etc. from occurring on the floor surface, a seat 20A functioning as a protective member is provided as a structural element in which a felt material or a carpet material is pressure-molded into a desired shape in a molding die. Therefore, the seat 20A can be easily deformed when receiving a reaction force from the floor surface due to the load of furniture together with the soft characteristics of the felt material and the carpet material, and thus even if the floor surface is a wooden floor, It doesn't hurt. Also, the bottom surface 2 of this seat 20A
Since 2 is also formed as a convex curved surface or a circular surface with a rounded periphery toward the floor surface on which furniture is installed, the contact area with the floor surface and the contact friction force are reduced,
Therefore, it is possible to smoothly move the furniture through the pedestal 40 when installing the furniture.

On the other hand, the intermediate seat 30A is provided as the same functional element as the intermediate seat 30 in the pedestal 40 of the first embodiment described above, and therefore, for example, ABS.

When it does, it fulfills the detent function.

[0020]

As can be understood through the above-described embodiments of the present invention, according to the present invention, the pedestal used by being mounted on the legs of furniture or the bottom surface of the load supporting member is not the floor surface. While forming a smooth convex curved surface toward the contact surface side of the furniture, the furniture is easily deformed and buffered by the load reaction force from the floor surface against load load, and there is no peeling or missing. Since the pedestal for furniture has a cradle that is completely integrated with the nail element that is fastened to the load-bearing part and the molding seat of the synthetic resin material, the cradle according to the present invention is installed. When the furniture is installed on the floor surface, the fear of damaging the floor surface with scratches, drags, dents, etc. is eliminated, and the furniture can be smoothly moved.

Further, unlike the conventional structure in which the seat directly contacting the floor surface is adhered and fixed, the seat has a structure in which it is integrated with the driving leg by using a thermoplastic synthetic resin material. Therefore, even when it is used as a pedestal for furniture on a floor with steps or grooves, the pedestal peels off when moving furniture,
There is no problem such as falling off, and therefore, there is an effect that the durability of the pedestal can be improved.

Further, according to the present invention, since cedar-like or mountain-teeth-like projection surfaces are formed around the shaft body of the driving leg portion, the surface of the intermediate seat is temporarily If the pedestal is fixed to the bottom of the load supporting member such as the bottom of the furniture, the pedestal will rotate with respect to the bottom of the furniture even if external force is applied during the use of the furniture. There is no problem, and the effect that it can be fixed stably is also exhibited.
