Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a rake tack. More specifically, the present invention relates to a rake portion that is firmly fixed to the handle portion, and that does not loosen even when used for a long period of time, and has excellent durability.
[0002]
[Prior art]
For cleaning gardens, rakes are used to collect fallen leaves and garbage. Conventionally used rake saddles have a rake attachment structure as shown in FIG.
That is, the rake tack is provided with a handle 1 and a fan-shaped rake 2 attached to the tip of the handle 1. The rake part 2 includes a plurality of split bamboos 21. The split bamboo 21 has a structure in which a claw portion 211 (see FIG. 1 described later) is formed by leaving the base portion 210 and dividing the tip portion side into three equal parts.
[0003]
The rake portion 2 is formed by overlapping the base portions 210 of the plurality of split bamboos 21 and spreading them into a fan shape. A portion where the base portion 210 is overlapped is the converging portion 20. An insertion hole (not shown) is formed in the central portion of the converging part 20, and a wire (not shown) is inserted into the insertion hole and is wound around and fixed to the converging part 20. Furthermore, the surface on the front side of the fixed converging portion 20 is in contact with the lower surface of the handle portion 1 on the tip portion side, and the wire 4b is fastened several times to be fixed to the handle portion 1.
[0004]
The boundary portion between the base 210 and the claw portion 211 of the split bamboo 21 is sandwiched between the front and rear surfaces of the bamboo sandwiching members 3 and 3a (see FIGS. 1 and 2 to be described later). The members 3 and 3a are spirally wound over the entire length of the holding members 3 and 3a by a covered wire 30 (see FIG. 1 described later) formed by covering the wire with polyvinyl chloride.
And the front end side of the handle | pattern part 1 is piled up on the upper surface of the center part of the clamping members 3 and 3a, and the nail is inserted through the disk-shaped washer, and the nail is bent outside the clamping member 3a on the back side. ing. In this way, the rake part 2 is fixed to the handle part 1.
[0005]
Further, in the rake part 2, the claw part 211 is connected to the front part side of the sandwiching members 3, 3 a by the covering wire 22 so as to be knitted over the entire width from one end to the opposite other end. In this way, the tip side of the rake part 2 is reinforced to prevent the claw part 211 of the split bamboo 21 from being scattered during use.
[0006]
[Problems to be solved by the invention]
However, the conventional rake fence described above has the following problems. That is,
(1) The converging part 20 of the rake part 2 is attached to the handle part 1 by tightening with a wire 4b. Since the wire 4b has a circular cross section and a small diameter, the contact area with the converging portion 20 is small, and the fixing force is not sufficient.
Therefore, when the rake portion 2 is easily loosened during use, and when the split bamboo 21 is dried and thinned due to long-term use, the perimeter of the converging portion 20 is shortened, and further loosening progresses and cannot be used. It was.
As a result, it was abandoned as it was or was wound up with a new wire and repaired for use again, but it was troublesome and cumbersome.
[0007]
(2) The holding members 3 and 3a holding the rake part 2 on the front and back sides are fixed to the tip part of the handle part 1 with a nail and a washer. Since this washer is disc-shaped, that is, a flat plate, only a part of the washer is in contact with the arc-shaped surface of the handle 1 made of bamboo, and the handle cannot be protected. For this reason, when a load is applied to the fixed part during use, the nail hole is easily cracked, and the durability is not sufficient. Moreover, since the metal washer projects from the surface of the handle 1, there is a problem that it is easy to get injured.
[0008]
(3) In order to prevent the claw portion 211 of the split bamboo 21 from being scattered, the covering wire 22 is connected at two places in the front and rear so as to be knitted over the entire width from one end of the rake portion 2 to the other opposite end. However, since the covering wire 22 connecting the claw portions 211 is poor in flexibility and elasticity, the flexibility and elasticity inherent in the claw portions 211 are hindered and are not easily deformed. For this reason, the nail | claw part 211 is hard to elastically deform, for example, since the ground etc. which are cleaned are not flat and there are many uneven parts, a clearance gap will arise between the grounds, and it is difficult to collect without leaving fallen leaves and dust etc. It was difficult.
[0009]
(Object of the present invention)
An object of the present invention is to provide a rake tack that is excellent in durability by preventing the portion where the converging portion of the rake portion is attached to the handle portion from being loosened.
Another object of the present invention is to protect the handle by increasing the contact area with the handle surface of the washer used at the portion where the holding member portion holding the rake portion on the front and back sides is attached to the handle. A rake bar that prevents the injuries by preventing the washer from protruding from the surface of the handle while preventing the handle from cracking even if a load is applied to the fixed part during use. Is to provide.
Still another object of the present invention is to reinforce for preventing flaking without hindering the inherent flexibility and elasticity of the split bamboo claws, leaving no leaves or dust on the ground with many irregularities.
