Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a handy type mower used for cutting grass.

[0002]

2. Description of the Related Art Generally, two types of conventional handheld type mowers, a manual type and an electric type, are widely used. And the former manual type mower
The so-called cutting scissors is composed of a pair of blades that are pivotally supported in an openable and closable manner, and a pair of handle portions that are connected to the blades. Thus, the lawn grass can be trimmed by opening and closing the handle while lifting the trimmer itself to a certain height. The latter electric mower uses the power of the engine to rotate the blade part provided at the tip of the mower. It is structured so that it can be carried on the shoulder with the blade of the tip part slowly swiveled to the left and right while turf grass is cut automatically.

[0003]

However, in such a conventional handheld type mower, whether it is a manual type or an electric type, it is different from a large-scale one with wheels. When working, whether it is lifted by hand or shouldered, it is necessary for the worker to float the blade part above the ground at a certain height before carrying out the work. Not only is this required, but with this, it becomes extremely difficult to proceed with work while keeping the height of the blade constant, and the height of the mowed turf grass also becomes uneven. I had a problem.

[0004]

SUMMARY OF THE INVENTION The present invention was developed to effectively solve various problems of the conventional handheld type trimming machine. As a result, a configuration is adopted in which a guide spacer having a shape that allows slipping on the ground and a predetermined height dimension is attached.

[0005]

Therefore, according to the present invention, regardless of whether the trimmer is a manual type or an electric type, a guide spacer is attached to the lower surface of the blade portion side, Can automatically lift the blade to a height according to the height of the guide spacer by simply grounding the guide spacer on the ground without forcibly lifting or carrying the entire trimmer. Therefore, unlike the conventional method, the pruning work does not require a heavy labor. Moreover, in this case, since it is possible to proceed the work while sliding the guide spacer on the ground, it is needless to say that it is most suitable for a long-term pruning work. Since it is also possible to continuously mow the grass to a uniform height according to the height dimension of the guide spacer, the height of the mowed turf is never uneven as in the conventional case.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to an illustrated embodiment. The trimming machine according to the embodiment was developed as a manual type so-called trimming scissors and has a basic structure. As in the conventional case, as shown in FIG. 1, a pair of blade portions 1 and 2 pivotally supported to be openable and closable via a pivot 5 with a knob 5a.
And a pair of handle parts 3 and 4 connected to the ends of the blade parts 1 and 2, and it is premised that the turf grass is cut by opening and closing the pair of handle parts 3 and 4. However, the feature is that the following configuration is adopted.

That is, in the present embodiment, first, as shown in the drawing, the end portions of the pair of blades 1 and 2 are bent upward, and the handle portions 3 corresponding to the respective curved end portions are bent. By fixing the lower end of 4 with a rivet 6 or the like, the pair of handle parts 3 and 4 are connected so as to stand up at a certain angle upwards, while ensuring a work in an upright posture without difficulty. The respective handle parts 3 and 4 are defined by two pipe materials 3a, 3b, 4a and 4b inside and outside and the joint cap 7, and the height of the handle parts 3 and 4 can be freely adjusted according to the height of the worker. It can be expanded and contracted. In the figure, 8
Is a reinforcing convex portion formed in each end side curved region of the pair of blades 1 and 2.

In addition to this structure, the present embodiment
The following guide spacer 9 is replaceably attached to the tip of the pivot 5. The guide spacer 9 is integrally formed as a curved body having a semi-oval shape or the like with a synthetic resin material or the like, and has a screw hole portion 10 into which a male screw 5b formed at the tip of the pivot 5 is screwed at the center thereof. And a stopper wall 11 for preventing co-rotation with the pivot 5 is provided on one side of the upper surface.

Therefore, under the present embodiment, the pair of blades 1
Inserting the tip of the pivot 5 into the through holes 1a and 2a formed in 2 and inserting the male screw 5b formed at the tip of the pivot 5 into the screw hole 10 of the guide spacer 9. When the pivot 5 is rotated in a predetermined direction by using the knob 5a while facing it, as shown in FIGS. 2A and 2B, the lower blade portion 2 of the stopper wall 11 is brought into contact with the ridge (both sides). (Rotation prevention state), the pivot 5 and the guide spacer 9 are easily screwed together, and the guide spacer 9 is easily attached to the lower surface of the shaft supporting point of the blade portions 1 and 2 and at the same time, the pair of blades is The parts 1 and 2 are pivotally supported so that they can be opened and closed.

Therefore, when mowing turf grass by using the manual mowing machine having such a structure, as shown in FIG. 3 and FIG. Simply by grounding the curved surface of the guide spacer 9 on the ground 12 and supporting the pair of handle parts 3 and 4 as they are, the pair of blade parts 1 and 2 can be moved to a height corresponding to the height dimension of the guide spacer 9. Since it can be automatically floated, the rest of the pair of handle parts 3 and 4 can be used in the same manner as in the conventional case.
Repeated opening and closing operations of the pair of blades 1
・ In step 2, you can continuously trim grass. Further, in such a trimming operation, the stopper wall 11 of the guide spacer 9 is only in contact with the ridge of the lower blade portion 2, so that the opening / closing movement of the pair of blade portions 1 and 2 is hindered. You never fear.

In addition, in the present embodiment, as described above, the pair of handle portions 3 and 4 are constructed as elongated members which can be extended upward, so that the operator is not unreasonable. Since it is guaranteed that the work is continued in the upright posture, the presence of the guide spacers 9 combined with the upright posture can dramatically improve the cutting workability.

Moreover, in this case, the guide spacer 9
By positively utilizing the curved surface of the above, it is possible to proceed with the work while sliding the guide spacer 9 on the ground 12 by simply pushing the pair of handle portions 3 and 4 forward while maintaining the grounded state. Since it is possible, it is needless to say that it is most suitable for a work for a long time, but in particular, it is also sufficient to automatically trim grasses to a uniform height according to the height dimension of the guide spacer 9. Since it is possible, the height of the mowed turfgrass does not become uneven as in the past. Therefore, under the present embodiment, it is possible to arbitrarily adjust the height of the turf grass to be cut, by preparing a number of types of guide spacers 9 having different height dimensions and appropriately selecting and using them. It can be said that its practicality is extremely enormous.

In the above embodiment, the pivot 5 for pivotally supporting the pair of blades 1 and 2 is used for mounting the guide spacer 9, but the present invention is not limited to this. If the structure does not hinder the opening and closing movement of the pair of blades 1 and 2, the guide spacer 9 is attached to the lower surface side of the blades 1 and 2 by using other means. Is also possible.

The target trimming machine itself is not limited to a manual type called trimming scissors, and although not specifically shown, it is an electric motor that uses the power of the engine to rotate the blade portion. Even a type can be sufficiently dealt with by simply replacing the guide spacer 9 on the lower surface side of the portion rotatably supporting the blade portion. In this case, even if the heavy electric mower is carried on the shoulder with a band or the like to perform the work, the guide spacer 9
Since it is always grounded on the ground 12, it is not necessary to support the entire weight of the mower with shoulders as in the conventional case, and guidance by the guide spacer 9 can be expected even when the blade portion is swung to the left and right. Therefore, after all, the mowing work becomes easy, and there is no concern that the height of the mowed grass may be uneven.

[0015]

As described above, according to the present invention, by adopting the above-mentioned configuration, the blade portion can be simply grounded on the ground without having to lift or carry the entire trimmer at the time of trimming work. Since it is possible to automatically float the trimmer at a height according to the height dimension of the guide spacer, it is convenient to handle the trimmer itself during the work. In addition, it is possible to work while sliding the guide spacers on the ground, which is ideal for long-term mowing work, and at the same time the turfgrass has a uniform height according to the height of the guide spacers. Since it is possible to mow continuously, there is no concern that the mowed grass will be uneven in height. Further, since the present invention requires only the guide spacers, there is an advantage that the cost is not high and that the present invention can be easily applied to existing mowers currently used.
