Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for manufacturing leg protection and sliding members for chairs, tables, beds, furniture, etc.

[Conventional technology]

Tedra fluorocarbon ethylene sheets have a low coefficient of friction and are highly removable, making them slippery. Taking advantage of this property, the Tedra fluorocarbon ethylene sheets are pasted onto sponge surfaces on the legs of chairs, tables, beds, and furniture. There is a very easy way to attach a protective sliding member that has an adhesive surface for adhering the legs to the surface.

[Problems with conventional technology]

According to the method described above, chairs, tables, beds, and furniture can be moved smoothly, making cleaning easier and protecting carpets, etc., mainly when cleaning at home. Furthermore, the chair can be moved smoothly when seated or when leaving the seat.

However, the simple structure of a Tedrafluorocarbon ethylene sheet pasted on the surface of a sponge has poor sliding properties when it comes to carrying quite heavy objects, and it also has poor sliding properties for chairs, tables, etc. in hotels, restaurants, etc.
In areas where beds and the like are frequently moved, they are easily damaged and have poor durability, making them unusable for commercial purposes.

Therefore, it is ideal that the member to serve as the base is made of a hard synthetic resin material, while having a Tedrafluorocarbon ethylene sheet on the surface. However, there is no such protective or sliding member, and if it were to be manufactured, it would have to be manufactured using expensive and large-scale equipment such as injection molding or blow molding.

In the case of the present invention, even if it is a considerably heavy object, it will not be damaged or its sliding properties will not be deteriorated, and even in jobs such as hotels, restaurants, etc. where chairs, tables, etc. are moved extremely frequently, it will never be damaged. Our first objective is to provide a method for manufacturing a protective sliding member that maintains suitable sliding properties at all times, is highly durable, and can completely protect carpets without damaging them. 1 purpose.

The second object of the present invention is that it can be applied to any shape of the leg without requiring expensive and large-scale equipment, such as injection molding or blow molding, which requires a mold, and is inexpensive, easy, and quick. Another object of the present invention is to provide a method for manufacturing a suitable leg protection and sliding member for chairs, tables, beds, furniture, etc. as described above.

[Means to solve the problem]

The above-mentioned problems are caused by the process of forming a Tedrafluorocarbon ethylene sheet into a top opening having a bottom and a peripheral wall by press working using a female mold and a male mold, and by positioning the leg attachment members on the bottom of the top opening. Chairs, tables, beds, furniture characterized by the process of standing upright on a pre-standardized hardening agent-added polyester resin, and then pouring and molding the hardening agent-added polyester resin thereon. The problem is solved by a method for manufacturing a leg protection and sliding member such as the above.

〔Example〕

FIG. 1 shows an embodiment of the present invention,
A Tedrafluorocarbon ethylene sheet 4 is pressed by a female mold 2 and a male mold 3 in a press device 1 to form a top open body 7 having a bottom portion 5 and a peripheral wall portion 6.
form.

A chair, a table,
Polyester resin 9 made by adding a hardening agent after erecting leg attachment members 8, 8 for beds, furniture, etc.
The chair of the present invention is made by pouring and solidifying the
A method for manufacturing leg protection and sliding members for tables, beds, furniture, etc. is completed.

In the embodiment shown in FIG.
A polyester resin 9 with a hardening agent added thereto is poured in advance and solidified, and after the leg attachment members 8, 8 are erected thereon, a polyester resin 9 with a hardening agent added thereto is poured again and solidified. It is something. The embodiment shown in Figure 1 can also exhibit sufficient strength, protection, and sliding hardening, but according to this embodiment, even if the object is considerably heavy or is moved extremely frequently. Even when attached to the legs, the leg attachment members 8, 8 are semi-permanently attached to the Tedrafluorocarbon ethylene sheet 4.
There is no risk of it breaking through.

The leg attachment member 8 may be a nail-shaped member with a sharp tip for driving as shown in FIGS. 1 and 2, or it may be screwed onto the leg as shown in FIG. It may be in the form of a bolt with a threaded groove, or it may have a protrusion (not shown) having a slightly larger diameter than the hole that is pushed into and fixed in a hole previously formed in the leg. Any means may be used as long as it is securely fixed to the leg, such as a rod-shaped body.

〔Effect of the invention〕

However, according to the present invention, it is possible to achieve robustness and strength without requiring expensive and large-scale equipment, such as injection molding or blow molding, which requires a mold.
A highly durable leg protection and sliding member can be manufactured easily and inexpensively, and in the present invention, by changing the female die and male die in the press process, any leg part can be manufactured easily and inexpensively. Protective and sliding elements can be created according to the configuration.

In addition, unlike simple home-use leg protection and sliding members that have an adhesive surface for adhering the legs on the surface and a Tedrafluorocarbon ethylene sheet on the opposite side, this material is suitable for hotels where chairs, tables, etc. are frequently moved. , restaurants, etc., there is no risk of damage to chairs, tables, etc. even if they are moved repeatedly. In addition, it can reliably support and slide quite heavy objects, and because it is highly durable, it is possible to move chairs, tables, beds, and furniture extremely smoothly when cleaning or when leaving or leaving seats, and it can also be used to move carpets. It also serves as protection and is extremely useful.
