DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scissor, and more particularly to a scissor structure effective as a horticultural scissor or a flower scissor.

[0002]

2. Description of the Related Art Conventional horticultural scissors, flower garden scissors, and general office scissors have a pair of blades pivotally supported at a fulcrum O, and a handle is attached to a core portion closer to the base than the fulcrum. In this case, the object to be cut is simply cut by the blade at the front end. The shape of the blade body and the shape of the handle are variously devised depending on the purpose and use.

[0003]

The conventional scissors have a function of only cutting an object to be cut with a blade portion. Generally, cut ends of cut flowers in gardening scissors need to be cut sharply. However, depending on the tree species, a sharp cut may cause poor landing. In many cases, the cut flowers of poorly landed tree species are promoted by crushing the stalk at the cut end so that the stalk formation layer and the like are in contact with water as much as possible. An object of the present invention is to obtain scissors capable of performing operations such as crushing the stems of such poorly landed flowers.

[0004] Not only when the stems of the flowers are crushed, but also when the parts that cannot be cut by the blades 1b and 2b can be cut during use as general scissors. is there. Another object of the present invention is to provide scissors capable of performing a crushing operation in such a case.

[0005]

In general, a pair of scissors is provided with handles 3, 3 on cores 1a, 2a of a pair of blades 1, 2 which are supported at a fulcrum O.
4, and the cutting operation is performed by the blade portions 1b and 2b located ahead of the fulcrum O. The present invention provides a handle 3, which is attached to the cores 1a, 2a.
Pressing portions are formed on a part of the pressing member 4 so as to face each other with a constant width and approach each other. The handles 3, 4 attached to the cores 1a, 2a are formed of a relatively soft molding material, and the pressing members 5, 6 attached to the bases of the handles 3, 4 are more compact than the materials constituting the handles 3, 4. It is preferable to form with a hard material. In order to form the squeezing members 5 and 6, a portion corresponding to the inner upper end portion of the handle is molded in advance with a synthetic resin material, and the squeezing members 5 and 6 may be insert-molded when the handles 3 and 4 are molded.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the scissors of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a front view of the entire scissors. The scissors in the illustrated example have a straight blade, and are mainly intended for scissors for gardening.
It can also be applied to pruning shears, flower cutting scissors, and other office shears with curved blades.

The scissors shown in FIGS. 1 and 2 have a straight blade 1b.
And a blade body 1 having a core 1a, and a blade body 2 having a linear blade portion 2b and a core 2a are pivotally supported at a fulcrum O. Core 1a of blade 1
, A separately molded handle 3 is attached to the core 2a of the blade body 2, and scissors are formed.

The handles 3, 4 are integrally formed of a relatively hard synthetic resin material as a whole, and a part thereof is provided with a pressing portion which is located at an opposing position and which can be approached to each other. The squeezed portion provided on the handle 3 and the squeezed portion provided on the handle 4 may be located at positions opposing the handles 3 and 4, respectively, but it is preferable that the squeezed portion is provided on the base so that a large squeezing force can be obtained with a small force. .

In order to form a pressing portion on the handles 3, 4,
The handle itself is molded using a relatively strong synthetic resin material, and a fixed width, for example, 5 to 10
The shape of the squeezed portions, whose surfaces having a width of about millimeters are opposed to each other and which can be approached to each other by operating the handle, may be formed integrally with the main portion of the handle. However,
At the base of the handle, specifically at the upper inside of the handle, squeezing members 5 and 6 formed of a material harder than the handle are arranged, and when the handle itself is formed of a relatively flexible material, a hand holding scissors is provided. In addition to being able to be gentle and not easily fatigued, it is possible to provide a squeezed part having a strong squeezed portion and to be able to handle a relatively hard squeezed object and to be easy to handle.

[0010] For example, a relatively soft synthetic resin material can be used as a molding material for forming the handle, and a relatively hard synthetic resin material can be used as a molding material for forming the compressed portion. The combination of the material forming the handle and the material forming the squeezed portion can be arbitrarily selected. The present inventors molded the handles 3 and 4 using trans-1,5 polypentenamer (TPR), which is a kind of synthetic rubber, and used rigid polyethylene (PE) as the pressing members 5 and 6.
By using, scissors which are soft and easy to handle and have a durable pressing part, and which are harmless even if this handle is discarded in the future, can be obtained.

FIG. 4 is a perspective view showing an example of the pressing members 5 and 6 formed of a synthetic resin material. The squeezing member has a cross-sectional shape that is substantially U-shaped and is shaped to fit into the core of the blade body from inside, and the squeezing surfaces exposed on the inner surfaces of the handles 3 and 4 are 2 cm in length and 2 cm in width. The surface is about 7 mm. As shown in FIG. 4A, lateral unevenness 7 is formed on the surface of the pressed surface to prevent slipping. As shown in FIG. 4B, a vertical ridge 8 is projected from the back of the pressing members 5 and 6, and when the pressing members 5 and 6 are inserted into the handles 3 and 4, The area of contact with the molding materials 3 and 4 is increased, so that they are adhered as firmly as possible and can be integrally molded.

FIG. 3 is a cross-sectional view taken along the line III-III of FIG. 1, and it is possible to understand the state of the squeezing member which is insert-molded on the upper inner surfaces of the handles 3 and 4. That is, the squeezing members 5, 6 are formed so as to mesh with the handles 3, 4, and act when the squeezed object A is squeezed from the state of FIG. 3 (a) to the state of FIG. 3 (b). The reaction force is supported by the blade cores 1a and 2a, and no force acts in the direction in which the squeezing member is separated from the handles 3 and 4.
The handles 3 and 4 are molded in a state in which through holes into which the cores 1a and 2a of the blades 1 and 2 are to be inserted are formed.
Although the scissors are completed by fitting and inserting into the 2a, the scissors may be formed by inserting the cores 1a and 2a of the blades 1 and 2.

FIG. 2 is a front view of the entire scissors in which the handles 3, 4 are longitudinally sectioned. In the embodiment shown in FIG.
The contact portions 1c and 2c are projected inward to the core base of 2 and the contact portions 1c and 2c come into contact with the blade body in the most closed state, and the pressing members 5 and 6 come close to the extent that they come into contact with each other. However, the opening / closing force of the blade is supported by the contact of the contact portions 1c and 2c. This prevents the pressing members 5 and 6 from being worn out or damaged due to long-term use of the scissors.

[0014]

According to the scissors according to the first aspect of the present invention, it is possible not only to cut the object to be cut with the blade portion of the blade body but also to perform the work of crushing with the pressing portion. Therefore, when using as scissors for horticulture or scissors for flower arrangement, the shaft of flowers can be crushed to promote landing. Further, when used as general scissors such as office scissors, it can be used in a case where an arbitrary three-dimensional object is crushed, flattened, and cut with scissors.

According to the second aspect of the present invention, in carrying out the first aspect of the present invention, the handle is formed of a soft material that is gentle on the hand, and the squeezing portion for performing the crushing operation is formed of a material harder than the handle. Because of the formation, scissors can be efficiently performed and scissors can be used easily.

According to the third aspect, the scissors according to the second aspect can be manufactured efficiently.

According to the fourth aspect of the present invention, since the opening / closing force of the scissors is supported by the abutment of the contact portions 1c and 2c, the squeezing member is worn out or damaged with long-term use of the scissors. Is prevented.
