BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a reel case of a nylon cord type brush cutter, and more particularly, to simplify the operation of feeding out a nylon cord wound around a winding portion of a reel case body. The present invention relates to a reel case that can be used.

[0002]

2. Description of the Related Art Conventionally, a brush cutter using a nylon cord has been proposed as a brush cutter for weeds and the like, and is provided for the convenience of consumers.

In this nylon cord type brush cutter, the tip of a nylon cord wound around a winding portion of a reel case main body is extended from an appropriate one of a plurality of spouts formed in a side wall of the case main body, and a reel case is provided. Is rotated at a high speed to perform weeding and other mowing operations using centrifugal force acting on the feeding portion of the nylon cord.

[0004] When the feeding portion of the nylon cord is worn and shortened due to a mowing operation or the like, the end portion of the feeding portion is once drawn in from the feeding port and rewound so that the feeding portion becomes longer. This feeding part is inserted through an appropriate feeding outlet of the above and used for drawing.

It is preferable that the pulling-out operation of the feeding portion can be easily performed because the mowing operation is often interrupted. However, in practice, the end portion of the feeding portion is once pulled in from the feeding outlet. However, it has been pointed out that there is a problem to be solved such that the operation must be performed after rewinding, and then inserted into another feeding port and pulled out again, which is troublesome and therefore lowers the work efficiency.

[0006]

Therefore, in the present invention,
A nylon cord feeding outlet is opened on the side wall, and a flange member is provided on the opening surface of the winding part of the case body having the nylon cord winding part provided inside the side wall, and the nylon cord is wound on the winding part. In the reel case, the outlet of the nylon cord and the opening edge of the side wall communicate with each other through a slit extending in the axial direction, and the outlet is extended in the circumferential direction of the case body around the slit. The cord is formed into an elliptical shape, and a projection for locking the nylon cord is formed at the boundary between the outlet and the slit. And the cord is prevented from deviating through the slit when not in use.

[0007]

[0008]

[Operation] In the reel case according to the present invention, when the feeding portion of the nylon cord is shortened due to abrasion due to mowing work or the like, the end portion of the feeding portion is once passed through a slit communicating with the feeding outlet from which the cord is drawn out. After being pulled out and rewound so that the feeding portion becomes longer, the feeding portion is extended by inserting it into an appropriate slit on the rotation direction side and pulling it out from the feeding port as it is.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a reel case in a nylon cord type brush cutter according to the present invention will be described below in detail with reference to the accompanying drawings.

In FIG. 1, a reel case 10 according to the present invention has a case body 12 formed by aluminum die casting.
And the winding portion 1 also serving as a hub of the case body 12
For example, after attaching the hat-shaped flange member 16 using a means such as caulking, a nylon cord 18 as a brush cutter is wound around the winding part 14.

On the other hand, a feed port 20 is formed on the side wall of the case body 12 at a position deviated by 90 degrees along the circumferential direction thereof. Each feeding port 20 and the opening edge 12a of the case body 12 communicate with each other through a slit 22 extending in the axial direction, and the nylon cord 1 wound around the winding portion 14 is provided.
The distal end 18 a (extending portion) of the extension 8 extends to the outside through an appropriate outlet 20.

In this case, the shape of each of the outlets 20 may be basically circular, but as in the present embodiment, a length extending symmetrically in the circumferential direction of the case body 12 with the slit 22 as a center. A circular shape and the elliptical outlet 20
It is preferable that projections 24, 24 for locking nylon cords are formed at the boundary between the slits 22 and the slits 22 (see FIG. 2).

A lower opening 26a of the case body 12 is provided.
Is open, but in the case of the reel case 10 of the type in which the upper part of the case main body 12 is opened as shown in FIG. 3, the disc-shaped lid member 2 is inserted into the upper opening 26b.
It is preferable to dispose 8 and fix it by means such as caulking.

As shown in FIGS. 4 and 5, the case body 12 made of aluminum die-cast is formed such that each of the outlets 20 formed in the side wall 12b of the case body 12 is drawn outward in the radial direction of the side wall. And a vertical mold 32 which is pulled out in the axial direction of the case body 12.

In addition, both ends 20a and 20b of the opening of the feeding port 20 formed by the dies 30 and 32.
Is formed as an arc-shaped portion R having as large a curvature as possible, and this arc-shaped portion R is finished by shot blasting or the like without performing machining finish.

In the reel case 10 according to the present invention configured as described above, the distal end 18 of the nylon cord 18 is provided.
a, that is, the feeding portion is rotated while being in contact with the large arc-shaped portions R at both ends of the opening of the feeding port 20, so that the feeding portion is not easily cut. Further, the opening shape of the feeding port 20 is made oval and the projection 24 is provided at the boundary with the slit 22, so that the nylon cord 18 is locked by the projection 24 when not in use. There is no inconvenience such as deviating to the outside through the interface.

Further, when the feeding portion of the nylon cord 18 is shortened due to abrasion work or the like, the slit portion 22 communicating the feeding portion end 18a with the feeding port 20 is formed.
, And then, after being unwound so that the feeding portion becomes long, it may be inserted into an appropriate slit 22 on the rotation direction side and pulled out from the feeding port 20 communicating with the slit 22 as it is.

[0018]

As described above, in the reel case according to the present invention, the slit is formed at the feeding port so as to communicate with the opening edge of the case body. Not only is it easy to guide to the outlet, but also the pulling-out operation of the end of the feeding portion shortened due to wear can be performed extremely easily, so that the working efficiency can be improved.

Further, since the both ends of the opening of the feed port are formed as arc portions having a large curvature, unnecessary cutting of the nylon cord can be prevented as much as possible. In addition, it has various advantages such as easy manufacturing and reduction of manufacturing cost, and its practical effect is extremely large.

Although the preferred embodiment of the reel case according to the present invention has been described above, the present invention is not limited to this embodiment, and various modifications can be made without departing from the spirit of the present invention. Obviously you can get it.
