Description

The present invention intersects the paired member consisting of the half body element having the blade body (action part) and the grasping body (operation part), and pivotally supports the intersection part so as to be rotatable or openable and closable. The present invention relates to a vertical manual instrument comprising a collision part or a stopper as a means for the grasping body, and more specifically, the dispersion of gripping pressure is augmented, and the generation of a striking force between the collision part or the stoppers during a cutting operation is eliminated or eliminated. The present invention relates to a saddle type manual instrument that is attenuated or extremely mitigates an impact on a finger caused by a generated striking force, and a grip attachment thereof.

Here, the application range (use) of the vertical hand-operated instrument relating to the present invention is a moth that shears (cuts) a relatively hard object (hard-to-cut material), such as a fruit culm, a fruit culm, a flower culm, It is designated as a sprout bud, a fresh flower bud, a gardening tub, a pruning / branch chopstick, an electric work jar, a carpenter jar, a hard-cut fiber cutting jar, and the like. In the present invention, “cut” and “shear” are used interchangeably. “Handle” and “grip” are synonymous with “grasping body (operation unit)”.

Conventionally, a general scissors is well known as a manual instrument for separating an object to be cut by opening / closing operations of a handle (same as a grasping body) provided on two blade bodies. Among them, some moss provided for horticultural use or agriculture use pine needle springs or coil springs on the inside of the handle, respectively, to urge the blades to open automatically. In addition, there is a case in which a shock absorber is provided at each of the collision parts formed to face the base leg body to which the two handles are attached, so as to reduce the occurrence of shock and collision noise during shearing (for example, Patent Document 1). See).
Utility Model Registration No. 3121120

However, with respect to the collision sound, there is one that has recognized technical significance in that it emits a pleasant sound to adjust the cutting operation contrary to attenuation (see, for example, Patent Document 2). Here, hard objects such as metal can be put in and out of the collision part inside the ring-shaped operation part (same as the grasping body) so that it can be inserted and removed freely (the contact condition can be adjusted) to ensure the generation of pleasant sounds and elastic A resin grip is used to absorb the impact of the collision.

In recent years, many grips of moss have been coated with a resin material such as synthetic rubber. The purpose of this application is mainly to prevent slipping and to provide a soft touch, and to the fingers during cutting operations. There is no one that has the objective effect of reducing the impact (see, for example, Patent Document 3).
JP-A-7-285084

However, there is a problem that it is difficult to prevent the finger from moving forward in the direction of the blade edge while repeating the scissors operation only by applying a resin coating to this kind of rod-shaped grip. For this reason, a finger stop is provided on the grip (see, for example, Patent Document 4), and many grips have protrusions or large curved portions.

( Reference Example 1)
The first reference example housing X1 covers the grasping body 12 (1) with the covering body 2 made of a single or composite soft elastic material. Here, the soft elastic material is rubber, silicon resin, or other elastic resin having appropriate hardness, which will be described later. With this configuration, the dispersion of the gripping pressure is increased, and the impact on the fingers caused by the occurrence of the striking force between the collision portion 13 (1) or the stoppers during the cutting operation is reduced. In addition, regarding the soft elastic material which comprises the coating | covering body 2, it is not ask | required whether it is a single material or a composite material.

The illustrated spring 5 is a known urging means, and always urges the grasping body 12 in the opening direction.

As shown in FIG. 1, the first reference example housing X1 has a grasping body 12 (handle) covered with a covering 2 made of silicon resin. Silicone resin is excellent in water repellency, heat resistance, cold resistance, and weather resistance, and is therefore suitable for outdoor work such as farming and horticultural work. If the Shore A hardness of the silicone resin is in the range of 15-50 (preferably 30-41), the pressure on the fingers is relieved by the elastic effect, and the muscle pump action of the finger muscles (blood flow due to muscle contraction and relaxation) It is suitable for long-time work because it improves muscle blood flow. In addition, it is preferable that the cross-sectional thickness of the covering 2 is 2 mm or more.

The first reference example body X1 was subjected to a comparative experiment on impact during cutting operation with Shore A hardness on 12 healthy male subjects with an average age of 44.0 ± 13.6 years [28 to 61 years]. The subject's attributes are that the dominant hand is the right hand, the finger length is vertical 18.1 ± 0.7cm [16.4-19cm], the first finger to the fifth finger width 8.6 ± 0.3cm [7.9 to 9.2cm], the first finger to the first The width of five fingers was 11.2 ± 0.6 cm [10.3 to 11.8 cm], the right grip strength was 50.2 ± 6.5 kg [40 to 62 kg], and the left grip strength was 47.5 ± 5.6 kg [37 to 57 kg]. The age ranged from the middle age to the elderly. None of the subjects were extremely biased in hand length or grip strength. Considered a standard group of subjects.

  Using the conventional and newly manufactured silicone resin Shore A hardness 15, 30, 41 and 50 gripper for 2 minutes, cut the chin for 2 minutes. The evaluation was compared. Table 1 shows the subjective symptom results of pain due to Shore A hardness of the thumb and 2-5 fingers (indicator, middle finger, ring finger, and little finger). The “Borg scale 10-point method” is used for the pain symptom test. The higher the score, the more pain is developed. The numerical data is an average value. Table 2 gives the subjects ranks (1-5) in order of decreasing finger burden with respect to the grip hardness. The numerical data indicates the average rank.

  As a result of Table 1, it was confirmed that a material coated with a silicon covering 2 having a Shore A hardness of 30 to 41 is less likely to cause pain and has a significant impact relaxation effect.

  As a result of Table 2, as with the subjective symptoms, it was evaluated that the silicon sheath 2 having a Shore A hardness of 30 to 41 was preferably covered with less finger burden.

In addition, for the first reference example housing X1, it is considered that the shape of the grasping body 12 is modified to be linear and slightly longer in order to improve workability and enhance the effect of the covering unless departing from the protection range.
