Description

The present invention relates to a reinforced grip made of a lightweight material, such as foamed resin, which is weak in compression and has low strength, and which has sufficient durability while maintaining lightness as much as possible.

Existing cardboard cooler boxes with handles do not have handles attached to the foamed resin material that keeps the cool, but rather to a separate material, the cardboard that covers the outside. If the contents become larger, the box will naturally become larger as a whole, using more resources and becoming heavier, since the foamed resin material that acts as the coolant must be enclosed and the handles made of a separate material must be formed on the outside (see Patent Document 1).

The above-mentioned materials are used in a variety of fields, but if a grip is made of only these materials, the grip tends to have low durability due to insufficient strength.

If you try to fix a handle or the like to the material using wood screws, drilling the wood screws into the soft material is like nailing a hole in the chaff, and it is extremely difficult as it can easily damage the material.

Foamed resins contain a lot of air, making them difficult to glue. It is impossible to glue anything to 100% air, but in the case of expanded polystyrene, it is said to be 98% air, making it a difficult material to glue anything to. It is also extremely difficult to glue handles or other items to such materials with adhesive.

Even if a handle or the like can be fixed to the material in some way, if the handle protrudes beyond the product, unnecessary external force or moment is likely to be applied to the handle, which can easily damage the joint surface with the handle. Therefore, it is desirable to provide a recessed portion to provide a grip for products made of flexible materials.

Providing a recess in the material to provide a grip ultimately requires less material and is resource-saving.

To provide a grip on a material without impairing lightness as much as possible.

If another material with sufficient strength is used to reinforce the material, the weight will increase, and repeated pressure can cause the grip to be compressed and thin, or the grip to be sheared off from the main body, which can lead to problems.

A reinforcing grip according to any one of claims 1 to 4, characterized in that it is a grip attached to the corner of a portable product made of a lightweight material such as foamed resin, the grip having a rectangular parallelepiped recess inwardly recessed at the corner of the product, bridging two parallel surfaces, with thin plates affixed to the top and bottom surfaces of the grip. The upper thin plate has an upwardly convex curved surface, and the lower thin plate has a downwardly convex curved surface, both of which are formed to conform to the cross section of the grip. The reinforcing grip according to any one of claims 1 to 4, further characterized in that a columnar strength member is disposed inside the grip so as to contact the upper and lower thin plates, the thin plates being made of resin, the columnar strength member being a bamboo stick, the longitudinal length of the thin plate affixed to the top surface of the grip portion being at least twice as long as that of the thin plate affixed to the bottom surface, and the grip does not contact any of the other two surfaces other than the two parallel surfaces bridging the recess.

By taking advantage of the light weight of the material and providing a grip that can withstand repeated use, it becomes easier for even elderly people and women to lift and carry the product, and the range of uses for lightweight materials in general can be expanded.

The edge seating support device 1 is formed in a thick, flat, inverted U-shape. It is made of a resin, metal hollow body, or foam, preferably polystyrene foam, and is lightweight, reducing the caregiver's risk of back pain and allowing them to sit frequently. The top and bottom surfaces of the edge seating support device 1 are flat, with 1a representing the armrests and 1b representing the backrest. The inverted U-shaped cutout at 1c is the seat without a seat surface. Textured tape 1d hangs down from the front of both armrests 1a and is attached and fixed to matching textured tape 1e, which has been previously attached to the bed frame (Fig. 1).

The edge sitting support device 1 has a grip part 1f on the rear side of the backrest part 1b (Fig. 2). After the person being assisted assumes an edge sitting position on the bed, the caregiver supports the person being assisted with one hand for safety, holds the grip part 1f with the other hand, turns it around from the back of the person being assisted, and sets it in place. The textured tape 1d on the front of both armrests hanging forward is attached to the mating textured tape 1e on the bed frame side.

Next, the flat U-shaped table 2 is placed on top so that it is in front of the person being assisted who is sitting on the edge of the chair. The left and right protrusions 22c of the table 2 are passed through the belts 2a wound around both armrests 1a, and support pins 2b that abut against the front of the armrests of the seating position support device 1 are inserted from above on both sides of the front of the table 2 to securely fix the table in place (Figures 4 and 5).

Alternatively, if the table 22 has support legs 22d extending downward from the inside rear of the left and right protrusions 22c, and the support legs 22d have anchor plates 22e extending outward on the left and right sides of their lower tips, it can be installed by inserting it horizontally from in front of the person being assisted who is sitting on the edge of the chair (see Figures 6 and 7).

The portable product 3 is a seating support device 1 (Fig. 1).

The reinforcing grip 4 is provided on the grip portion 1f (FIG. 2).

The reinforcing grip 4 is formed with a cross-sectional shape that makes it easy to hold (see Figure 11). It is made of foamed resin such as foamed polypropylene, foamed polyethylene, or foamed polystyrene. It is lightweight, flexible, and not very strong (see Figure 8).

Thin plates 5 made of lightweight material such as resin are attached to the top and bottom of the reinforcing grip, and are shaped to fit the grip and hold it in place (Figs. 9 and 11).

Inside the reinforcing grip sandwiched between the thin plates, a columnar member 6 made of a lightweight, buckling-resistant material stands upright so as to come into contact with the upper and lower thin plates 5 (Figs. 10 and 11).

The number of the columnar members 6 is set to an optimum value that can withstand pressure when gripped and avoids an increase in weight (Fig. 12).

The longitudinal length of the thin plate 5 attached to the upper surface of the reinforcing grip is at least twice as long as that of the thin plate 5 attached to the lower surface, thereby increasing the torsional rigidity during gripping (FIG. 13).

The entire reinforced grip can also be covered with anti-slip material.
