Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to pruning shears for pruning plants, etc.

[Problems that conventional technology and ideas try to solve]

Conventional pruning shears of this type all have round handles, so they have the problem of being slippery and difficult to apply force to.

The present invention aims to solve the above-mentioned problems and to provide pruning shears that are lightweight and have high strength and rigidity.

[Means to solve the problem]

In order to achieve the above object, in the pruning shears of the present invention, the opposing short sides are formed into a curved convex shape, and the long sides have shallow grooves formed on the surface. The handle body is constructed from a hollow rectangular aluminum profile, and a pair of plastic grip cover pieces are attached to the inner bottom surface of the shallow groove so that the cross-sectional shape of the grip part of the handle member is shaped. It is formed into a substantially elliptical shape.

[Effect]

The handle body is made of an aluminum profile with a substantially hollow rectangular cross section, and shallow grooves are formed on both long sides, making the handle body lightweight yet lightweight.
Its section modulus is large, resulting in high strength and rigidity.
Attach the cover piece to the inner bottom of the shallow groove,
By forming the cross-sectional shape of the grip portion into a substantially elliptical shape, it is easy to grip with force, and the hand does not slip easily.

〔Example〕

In FIG. 1, handle members 9, 9 of the pruning shears according to the present invention are shown. Cover pieces 7, 7 for grips made of
and a mounting connector 11 that is attached to the tip 10 of the handle body 5 and is made of a material such as nylon.
It is equipped with. The connector 11 includes a metal blade 1
The insertion handle portion 13 of No. 2 is fixed by press-fitting or the like.

Therefore, as shown in FIG.
has a substantially hollow rectangular cross section, and specifically, the opposing short sides 2, 2 of the cross section are formed in a curved convex shape, and the surfaces of the opposing long sides 3, 3 are formed in a curved convex shape. A shallow groove 4 is formed in 1. Further, by attaching the pair of cover pieces 7, 7 to the shallow grooves 4, 4, the cross-sectional shape of the grip portion 8 of the handle members 9, 9 is formed into a slightly angular, approximately elliptical shape. The cover pieces 7, 7 sandwich the handle body 5 from both sides, and specifically, are attached to the inner bottom surface of the shallow groove 4 in abutting manner to fix the cover pieces 7, 7 to the handle body 5. The coupling protrusions 15 provided at multiple locations on the back surfaces of both cover pieces 7, 7 are inserted into the insertion holes of the long pieces 3, 3, and then fixed using fixing tools 16 such as self-tapping screws. , the protrusion 15...
This is done by interconnecting the two.

As shown in FIG. 3, the cross-sectional shape of the cover piece 7 has an outer circumferential surface formed in a gentle arc shape, and anti-slip grooves 14 are provided at regular intervals in the longitudinal direction. Both sides 17, 17 of cover piece 7
is inclined in accordance with the shape of the shallow groove 4, and is in contact with the inner surface of the shallow groove 4.

The pair of cover pieces 7, 7 have slightly different shapes, and as shown in FIGS. 4 and 5, one cover piece 7 has a positioning protrusion 19 formed on its base end 18. On the other hand, as shown in FIG. 6, the base end 18 of the other cover piece 7 is formed with a small locking cylinder part 20 into which the protrusion 19 fits. Furthermore, the protrusion for the fastener is also different as shown in the figure. In addition, such a pair of cover pieces 7,
7 are connected to each other with the opposing surfaces 21, 21 of the base end portions 18, 18 in contact with each other, and constitute a substantially hemispherical base end portion 22 of the handle members 9, 9. As for the material of the cover pieces 7, 7, ABS resin or other soft/hard plastic is used.

As shown in FIGS. 7 and 8, the mounting connector 1
1 and 11 have a fitting part 23 that is fitted into the tip of the handle body 5, and a protruding part 24 that functions as a cushion when the metal blades 12 and 12 are closed.
Further, a mounting hole 25 is provided through which the handle portion 13 of the metal blade 12 is inserted and fixed. In addition, the mounting hole 2
An adhesive may be used to fix the handle 13 to the handle 5. In this way, the mounting connectors 11, 1
1 is one in which the cushion material is also used as a member for attaching the metal blade 12.

According to the above embodiment, the handle member 9 includes a plurality of parts,
In other words, since the connector 11, the handle body 5, and the cover pieces 7 are each constructed, the handle body 5 can be extruded from aluminum to have a uniform cross-sectional shape.

[Effect of idea]

Since the present invention is configured as described above, it produces the effects described below.

Since the cross-sectional shape of the grip portion 8 of the handle members 9, 9 is formed into a substantially elliptical shape, from an ergonomic point of view, the gripping hand does not easily slip and it is easy to apply force. Therefore, it can be said that it is suitable for pruning work that is usually carried out over a long period of time.

Since the handle body 5 is constructed from an aluminum profile with a substantially hollow rectangular cross section, it is lightweight, strong, and
Increases rigidity.

By providing the shallow grooves 4 on the long sides 3, 3 of the handle body 5, it becomes easy to firmly fix the cover pieces 7, 7 to the shallow grooves 4, and the handle body 5 can be easily fixed without increasing the weight. It is also advantageous in increasing the section modulus.

By attaching the cover pieces 7, 7, the cross section of the handle body 5 itself is approximately hollow and rectangular, while the cross section of the grip portion 8 can be made into an approximately oval shape that is easy to grip.
