Abstract

(57) [Summary] [Purpose] Wrapping around the grips of hand tools such as a saw handle helps prevent slipping, fits well on the palm, feels good to the touch, and is reasonably flexible and tired even after long-term use. Propose a non-slip handle with improved design so that it does not come out. [Structure] A soft elastomer molding strip in the shape of a hollow cord having a uniform cross-section along the longitudinal direction is wound around a handle instead of a conventional rattan.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 In the case of tools with a handle such as a hand saw, it has been a long-standing practice to wrap rattan or artificial rattan around the handle of the handle, but to enhance its anti-slip effect, The idea here is to propose an anti-slip handle that is designed to make it easier to fit in the palm.

[0002]

[Prior Art]

 Conventional wicker vine wrapping has a problem that the wicker roll surface is smooth and the texture is stiff, but it has been used for many years, so there are few attempts to improve it.

Imitation of rattan itself with synthetic resin is also known, but no significant progress can be found.

[0004]

[Problems to be solved by the device]

 The purpose of this device is to propose a non-slip handle that is devised so that the handle can be maintained for a long time while being used as a grip for the handle. By utilizing it, it is possible to secure a firm grip and to prevent slipping, and to firmly secure the handle to the handle at the beginning and end of winding.

[0005]

[Means for Solving the Problems]

 This invention consists of a molded strip of a soft elastomer in the shape of a hollow cord, whose cross-sectional shape is uniform along the longitudinal direction, and is wrapped around the outer circumference of the handle, and the handle is wound at the winding start end and winding end end respectively. It is a non-slip handle of a handle, characterized in that it is formed with a plurality of irregularities on the outer peripheral surface, and each of the molding strips has a plurality of hollow cords each having a longitudinal through hole. The molded strip is press-fitted and fixed together with the stopper plug into the mounting holes of the handle provided to receive the winding start end and the winding end end. A head of a shape and a leg that is concentric with the shape of the head and ends in a tapered shape with a slightly smaller diameter and a taper, and a stopper is attached to the leg along its arc circumference, May have multiple notches cut parallel to the underside of the chin Rinozomashii.

1 (a) (b) (c) and (d) show the plane, front face, bottom face and side end face of the anti-slip handle according to the present invention, and FIG. 2 (a) (b) 2C and 2C show cross sections AA and BB in FIG. 1B and a detailed cross section of the portion C in FIG. 2A.

In the figure, 1 is a handle made of wood or synthetic resin, and 2 is a non-slip member that is wound around the outer periphery of the handle 1 and is fixed to the handle 1 at both ends thereof, as in a conventional saw handle. It is composed of an elastomer molding strip 3 in the form of a hollow cord, which replaces the rattan vine that is wound and fixed.

As shown in the drawing, the handle 1 has a mounting metal fitting 4 usually called a back metal for detachably mounting a saw blade (not shown) at one end thereof. It consists of a steel piece with a U-shaped cross section that is folded back with a gap corresponding to the thickness, and the tail end hook is detachably fastened with the back ridge of the saw blade along the back of the gap. It is provided with a stop pin 5 and a restraining tip 6 made of a hard metal that promotes a holding force at the tip of the mounting member 4.

The slip stopper 2 is formed by winding a molding strip 3 made of an elastomer, especially a thermoplastic elastomer, around the handle 1 and winding start end s and winding end end e (see FIG. 1 (b)) of the handle respectively. Stick to 1.

As shown in detail by partially enlarging in FIG. 2 (c), the molding strip 3 has a hollow cord shape with a uniform cross section along the longitudinal direction, and a large number of serration shapes on the outer peripheral surface. By forming the irregularities 7 in the longitudinal direction, the pattern 1 can be tightly wrapped around the handle 1, and can be well fitted to the palm and further promote the anti-slip action.

As can be seen from FIG. 2 (c), the forming strip 3 is illustrated as a two-strip case, but it is formed as a multi-strand hollow cord having through holes 8 and 9, respectively, and the number of windings is reduced. The advantage is that the number of steps for assembling the handle 1 is reduced.

The molding strip 3 is made of an elastomer, that is, a rubber elastic body, and is a thermoplastic elastomer such as polystyrene (transparent), polyolefin (translucent), polyester (milky white), polyamide (translucent), It can be selected from 1,2-polybutadiene type (transparent), ethylene vinyl acetate type, polyvinyl chloride type, natural rubber type and the like, and it is particularly preferable to use one having excellent coloring property.

The winding start and winding end ends s and e of the molding strip 3 are pushed into the mounting holes 10 that are predrilled in the handle 1, and at this time, the stopper 11 is pressed together to fix them. . Needless to say, an adhesive may be used together here.

As shown in FIGS. 3 (a) and 3 (b), the stopper 11 has a head 12 in the shape of a ginkgo leaf and a cross-section of a slightly smaller diameter concentric with the plan view of the head 12 (see FIG. 3 (f)), and the leg 13 ends in a taper shape and is parallel to the lower jaw surface 14 of the head 12 along the arcuate arc shape. It is preferable to have a plurality of sharp notches 15.

[0015]

[Action]

 Since the molded strip of soft elastomer has a hollow cord shape with a uniform cross-sectional shape, when it is wrapped around the handle of a hand-saw saw, for example, it fits well on the outer circumference of the handle, making the work easier and starting winding , Both ends of the winding can be firmly fixed by pressing together with the stopper plug into the mounting hole of the handle. Since the surface of the handle with this molded strip wrapped around it is supple and soft to the touch, it retains a good tactile feel even during long-term work and is effective as a non-slip surface.

The molded strip preferably has a rubber hardness of 60 ° or less (Shore hardness), and since a thermoplastic elastomer is particularly used as the soft elastomer, most of them have excellent coloring property. It can be used as a distinctive display of the pattern under various coloring.

[0017]

【Example】

 Using four types of polyolefin-based thermoplastic elastomers (TPO; polypropylene blend ratio: 8: 2, 7: 3, 6: 4 and 5: 5), cross-sectional shapes are shown in Figs. 4 (a) (b) and (c). Figure 3 shows a three-hole, twin-hole, and single-hole hollow cord-shaped forming strip, which is wound around the handle of a hand-saw saw according to that shown in Fig. 1, and both ends are pushed into the mounting holes of the handle. Stuck in. As for the double hollow cord-shaped strips shown in Fig. 4 (b), the stopper (made of polypropylene) shown in Fig. 3 was pushed into the mounting hole of the handle together with the cord-shaped strips and fixed. The expected anti-slip action was realized.

[0018]

[Effect of the device]

 With this invention, the handle is wrapped around the handle of a tool such as a typical hand saw, and the ends of the handle are wrapped around the soft elastomer molded strip to prevent the handle from slipping. Contributes as a good anti-slip handle under continuous use over a long period of time.
