Buffer protection material

Abstract

Provides cushioning protection. [Solution] The cushioning protection material 1 of this invention is obtained by creating a rod-shaped hollow cylinder made of elastic synthetic resin and then making continuous spiral cuts 2 from the front to the rear end of the cylinder at any width, running from the outer wall to the inner wall. Regardless of whether it is cylindrical 5 or prismatic, it can be attached neatly and tightly to tapered objects such as table legs or curved objects such as chair armrests, without using adhesives.

Description

[Technical Field]

[0001] This invention relates to a protective material with excellent shock absorption properties that can be attached to the legs, armrests, and pillars of desks, tables, and chairs. [Background technology]

[0002] The present invention provides a protective material that prevents injuries caused by hitting parts of the body, such as hands, feet, or head, against the legs, armrests, or pillars of desks, tables, and chairs, and is particularly suitable for use in preventing accidents involving young children, etc. Conventionally, such protective material has been proposed as being made of a hollow cylinder made of an elastic material such as rubber, with part of the circumference of the cylinder cut along the longitudinal direction, as described in Patent Document 1. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-129588 Summary of the Invention [Problem to be solved by the invention]

[0004] However, there are many tapered legs of desks, tables, and chairs currently on the market, whether cylindrical or prismatic, and even if you try to apply the protective material described in Patent Document 1 to these legs, it is difficult to ensure good adhesion, resulting in the problem of floating. Furthermore, there is also the problem that correcting this floating requires the time-consuming task of tightening the floating part with cellophane tape or the like.

[0005] Furthermore, it is virtually impossible to apply the protective material described in Patent Document 1 to the curved portions of the armrests or backrest of a chair, and the current practice has been to apply commercially available cushion tape or the like. However, applying this cushion tape requires peeling off the release paper on the back of the tape and adhering it to the adherend with an adhesive. Furthermore, when peeling the tape, the adhesive cannot be removed cleanly from the adherend, which creates the problem of soiling the adherend. Furthermore, the current situation is that the cushioning effect is inferior to that of the cushioning protective material.

[0006] The present invention was made after extensive research in light of the above-mentioned conventional problems, and provides a cushioning protective material that can be attached neatly to tapered or curved adherends without the use of adhesives, because the elasticity of the material causes it to return to its original shape, allowing it to be fixed by the elastic pressure. [Means for solving the problem]

[0007] The cushioning and protective material of this invention is characterized by a rod-shaped hollow cylinder made of synthetic resin, with continuous cuts of any width spiraling from the front to the rear end, extending from the outer wall to the inner wall.

[0008] Furthermore, the above-mentioned synthetic resin is made of a resin containing an elastic elastomer as a main component, thereby solving the above problems. [Effects of the Invention]

[0009] As described above, the cushioning protection material of the present invention can be neatly attached to the legs of desks, tables, chairs, etc., whether cylindrical or prismatic, or tapered, or to the curved portions of chair armrests or backrests, without the use of adhesives, and is useful for preventing injury caused by body impacts. Furthermore, it not only prevents bodily injury, but also damage to the adherend as described above. Regarding the thickness of the adherend, the hollow cylindrical protection material of the prior art proposed in Patent Document 1 is limited by the hollow inner diameter, making it difficult to attach to objects with a larger outer diameter. However, the cushioning protection material of the present invention is limited by the expanded length from the front to rear of the cylinder, making it possible to attach to even fairly thick adherends. [Brief explanation of the drawings]

[0010] [Figure 1] 1 is a perspective view of a shock-absorbing protective material provided by the present invention; [Figure 2] 1 is a diagram showing the state in which the cushioning protective material is attached to a cylindrical adherend. [Figure 3] 1 is a view showing the state in which the shock-absorbing protective material according to the first embodiment of the present invention is attached to the tapered cylindrical leg of a table. [Figure 4] 10 is a view showing the state in which the shock-absorbing protective material according to the second embodiment of the present invention is attached to the tapered prismatic leg of a table. [Figure 5] 10 is a view showing the state in which the shock-absorbing protective material according to the third embodiment of the present invention is attached to the armrests, backrest, and legs of a chair. MODES FOR CARRYING OUT THE INVENTION

[0011] A rod-shaped hollow cylinder made of elastic synthetic resin is cut continuously in a spiral pattern from the front to the rear end at approximately equal intervals of any width, specifically 10 mm to 50 mm, preferably 20 mm to 40 mm, from the outer wall to the inner wall, to obtain the shock-absorbing protective material of the present invention as shown in Figure 1. There are no particular restrictions on the thickness of the protective material, but a thickness of about 2 mm to 10 mm is practically suitable.

[0012] Here, elastomer refers to a natural or synthetic resin with elastic properties, which means that it can elastically return to its original shape after being compressed and deformed. In this invention, synthetic resins are used instead of natural resins, and there are several types such as nitrile rubber (NBR), styrene butadiene rubber (SBR), butadiene rubber (BR), and isoprene rubber (IR), among which nitrile rubber (NBR) is preferably used.

[0013] The specific method for attaching the cushioning protective material to the adherend is to wrap it around the adherend in a manner similar to wrapping tape around the adherend, as shown in Figure 2. Furthermore, since it does not use adhesive like tape, it can be removed easily and cleanly. In other words, it is a cushioning protective material that can be attached and removed freely.

[0014] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. In the first embodiment of the present invention, a cushioning protection material made of nitrile rubber (NBR) with a thickness of 6 mm and a cut width of 30 mm was created, and the cushioning protection material was attached to the tapered cylindrical leg of the table shown in Figure 3 in the manner shown in Figure 2.

[0015] In the second embodiment, a shock-absorbing protective material with the same specifications as the first embodiment was created and attached to the tapered prismatic legs of the table shown in Figure 4 in the manner shown in Figure 2.

[0016] In a third embodiment, a cushioning protective material was prepared from nitrile rubber with a thickness of 3 mm and a cut width of 20 mm, and the cushioning protective material was attached to the backrest, the curved parts of the armrests, and the legs of the chair shown in Figure 5 in the manner shown in Figure 2.

[0017] Three examples have been described above as examples, but in all cases, it is possible to easily and neatly attach the product to tapered or curved adherends, and it is possible to create a safe environment without injury even when a child hits it with a part of their body such as their hands, feet, or head. Furthermore, the above examples are merely illustrative, and a wide range of applications can be expected. [Explanation of symbols]
