Description

  The present invention relates to a structure that prevents a slipper cover that covers a handle of a manual tool such as a gardening scissor or a manual tool such as a pliers from slipping out or peeling off.

The grip pattern of recent gardening scissors, pliers and other manual instruments and tools is soft on the grip handle surface to prevent the hand feeling and gripping when grasping, as seen in the following publicly known literature, for example. A non-slip cover is formed by covering a synthetic resin or a synthetic rubber having elasticity and elasticity with means such as dip coating (also called dip coating or dobbing), brush coating, spray coating or powder coating. It is common.
JP-A-5-25406 Japanese Patent Laid-Open No. 10-164980 JP 2004-81135 A JP 2004-121095 A JP 2004-20482 A Utility Model Registration No. 3032546 Utility Model Registration No. 3064425

  By the way, the non-slip cover covered with the grip handle of the manual instrument / tool is separated from the handle handle gradually by the force applied at the time of operation unless it has any retaining structure with the handle handle, Also, it may be peeled off due to wear / damage or cracks due to aging.

  In order to prevent this, in the above-mentioned ones, a retaining part or a catching part having a slightly larger diameter than the other part is formed near the rear end part of the grip handle, and the rear end part of the non-slip cover is hung. A small hole is formed in the grip handle, a small protrusion is formed on the resin inner layer member integrally formed with the non-slip cover, and the small hole is formed in the small hole. There is one in which a small protrusion is fitted and a non-slip cover is locked (for example, see Patent Document 3).

  However, to prevent the slip cover from being removed, both the grip handle has a larger diameter retaining part and a catch part than the other parts, a small hole is formed in the grip handle, and a small protrusion is formed on the cover side. There is a problem in that fitting is caused in the manufacturing process, and the manufacturing cost is increased.

  In addition, when the slip cover has a retaining part or a catch part in the vicinity of the rear end of the grip handle, if the anti-skid cover is worn or damaged or cracked due to age deterioration, the rear end Even if the part closer to the part, that is, the lower part is locked, it may gradually peel off from the front part, that is, the upper part (see, for example, FIG. 4). is there).

  The present invention has been devised to solve the above-mentioned problems associated with conventional anti-slip covers for manual use tools and grips of tools. That is, the purpose of the present invention is a simple structure, easy to manufacture, does not increase the manufacturing cost, and can maintain the effect of preventing the anti-slip cover from being pulled out and peeling off for a long time. An object of the present invention is to provide a structure for preventing the slipper cover from coming off and peeling off in the grip pattern.

The structure for preventing slipping off and peeling off the non-slip cover of the manual handle and tool grip handle according to the present invention is as follows.
In the non-slip cover 3 in which the peripheral surface of the handle 1 of the manual instrument / tool A is covered with a layer 2 of a synthetic resin or a synthetic rubber material having elasticity and softness,
Small grip holes 4 and 5 are formed at least at the upper and lower positions in the length direction of the grip handle 1 so as to communicate with the front and back surfaces. 3 is formed so that the layer 2 of synthetic resin or synthetic rubber material 3 communicates.

In other words, the above structure is as follows.
In the non-slip cover 3 in which the peripheral surface of the handle 1 of the manual instrument / tool A is covered with a layer 2 of a synthetic resin or a synthetic rubber material having elasticity and softness,
The anti-slip cover 3 is formed so as to communicate with the front and back surfaces through small through holes 4 and 5 that are formed at least at the upper and lower positions in the length direction of the handle 1 and communicate with the front and back surfaces. It has been done.

  In the present invention, the upper position means the position near the blade 7 and the position near the push spring 9 with the grip handle 1 or the anti-slip cover 3, and the lower position means the grip pattern 1 or the anti-slip cover 3. The position near the rear end shall be said.

  B) The anti-slip cover removal / peeling prevention structure for the manual use tool / grip handle of the above structure is shown at least in the upper and lower positions of the handle 1 in the length direction. A small through hole 4, 5 leading to the back is formed, and then a layer 2 of synthetic resin or synthetic rubber material having elasticity and softness is formed on the peripheral surface of the handle 1, for example, by dip coating (dip coating) ) Method or the like.

  Therefore, the anti-slip cover 3 with the structure for preventing slip-off / peeling can be formed simultaneously with the formation of the anti-slip cover 3 and the structure for preventing slip-off / peel off, and can be manufactured easily and quickly with a simple configuration. At the same time, it can be manufactured with almost no increase in cost compared to the conventional non-slip cover.

  B) The anti-slip cover 3 formed as described above is formed so as to communicate with the front and back surfaces through the small holes 4 and 5 communicating with the front and back surfaces formed on the handle 1. It is. That is, the layer 2 of the synthetic resin or the synthetic rubber material having elasticity and softness communicates the front and back surfaces so as to fill the small holes 4 and 5.

  For this reason, when the manual handle / tool is gripped by gripping the anti-slip cover 3 of the handle 1, even if a force in the direction in which the anti-slip cover 3 comes out of the handle 1 is applied, The anti-slip cover 3 communicating with the front and back surfaces through the small holes 4 and 5 can be prevented from coming out of the handle 1.

  C) Furthermore, the small through holes 4 and 5 for communicating the elastic resin layer 2 of the non-slip cover 3 on the front and back surfaces with at least the upper part in the length direction of the handle 1 It is formed at two locations, a shift position and a lower position.

  Therefore, even if this manual instrument / tool A is used for a long time and cracks occur due to fraying of the non-slip cover 3 or deterioration with time, the through holes 4 and 5 at least at the upper and lower positions should be provided. As it is filled, the anti-slip cover 3 communicating with the front and back surfaces is firmly integrated with the front and back surfaces, so that it can be peeled off not only from the lower position but also from the upper position. Can be prevented.

  In the above configuration, the manual instrument / tool A is a manual instrument such as various scissors, and is a manual tool such as pliers or pliers. The material of the handle 1 is not limited to a metal plate and has a C-shaped cross section, but may be a metal rod, plastic, or wood, and the shape of the handle 1 may be linear (for example, FIG. (Refer to FIG. 1 and FIG. 2), it may be curved.

  The material of the non-slip cover 3 that covers the peripheral surface of the handle 1 is preferably polyvinyl chloride resin, for example. If it is a soft material, for example, it may be an elastomer such as polyethylene resin or other synthetic resin or synthetic rubber.

  The small through holes 4 and 5 to be formed in the handle 1 are formed in at least two positions in the length direction of the handle 1 such as an upper side position and a lower side position. It is preferable to form them at regular intervals in place (see, for example, FIGS. 1 and 2). In the case of forming the hole 11 for locking the retaining ring 10 in the grip handle 1 on one side (right side in the figure), the small through hole 5 at the lower position may be omitted in the grip handle 1 on that side. (See FIGS. 1 and 2 above).

  The anti-slip cover 3 is formed on the peripheral surface of the handle 1 as a layer 2 of synthetic resin or synthetic rubber material. At that time, the synthetic resin or synthetic rubber material is placed in the small through holes 4 and 5. Also, the front and back surfaces communicate with each other through the small holes 4 and 5 in a filled state.

  As described above, the means for coating the non-slip cover 3 on the peripheral surface of the handle 1 is based on the dip coating molding (dip coating) method. Although it is optimal because it is easy to allow a synthetic resin or a synthetic rubber material to flow in, it is also possible to use brush coating, spray coating or powder coating, for example.

  FIG. 1 to FIG. 3 show an embodiment in which the anti-slip cover removal / peeling prevention structure of the manual handle / tool grip handle according to the present invention is used for horticultural scissors used for cutting trees, fruits and the like.

  The garden scissors A as a manual instrument here have the same appearance as the conventionally known garden scissors. That is, here, the pair of blade portions 7 and 7 are made of carbon tool steel (SK5) and have a shape that becomes narrower toward the blade tip. They can be opened and closed with each other.

  Also, on the other side portion 12 of each of the blade portions 7, 7, a grip handle 1, 1 made of mild steel plate (SPCC) and having a shape that is almost linear in the longitudinal direction is welded. However, the cross-sectional shape of the grips 1, 1 is a convex C-shaped cross-section C shape on the outer side surface, that is, the side surface in the opening direction (see FIG. 3). Note that a push spring 9 is interposed between the grips 1 and 1 to urge it toward the opening direction.

  Furthermore, when the side connected to the blade parts 7 and 7 is the upper part, the grips 1 and 1 are arranged on the peripheral surface from the lower end part on the opposite side to the position where the spring 9 is provided. Here, non-slip covers 3 and 3 made of polyvinyl chloride are coated, and a stop ring 10 is attached so as to span between the lower ends of the grips 1 and 1. The above is the same form as the known gardening scissors.

  In the present invention, each of the grips 1 and 1 is made of a mild steel plate having a thickness of about 1.6 mm in a C-shaped cross section. Before the formation, small through holes 4 and 5 are formed at equal intervals in the longitudinal direction on the outer surface portion having a convex curved surface. Here, there are three small holes 4, 4, 5, each having an inner diameter of about 4.5 mm at three positions: an upper position close to the location where the spring 9 is provided, a lower position on the other side, and an intermediate position thereof. 6 and 6 are formed. Further, here, since the grip 11 on one side (right side in the figure) is formed with a hole 11 for locking the retaining ring 10, the small handle 5 near the lower portion is omitted from the grip 1. It is. Of course, the small through holes 5 may be formed separately.

  The anti-slip covers 3 and 3 are formed by a dip coating method here, and the grips 1 and 1 having the small through holes 4, 4, 5, 6 and 6 as described above are used. After heating in advance and immersing in a tank containing sol-like polyvinyl chloride resin, the vinyl resin is adhered to the peripheral surface of a predetermined portion of each grip handle 1, 1 and heated to gel. Just immerse it in a water tank, cool it, and pull it up.

  As a result, the vinyl chloride resin non-slip covers 3 and 3 are formed on the peripheral surfaces of the grips 1 and 1 at predetermined locations. At the same time, the small through holes formed in the grips 1 and 1 are formed. 4, 4, 5, 6 and 6 are filled with the sol-like polyvinyl chloride resin so that the non-slip covers 3 and 3 have small through holes 4, 4, 5, 6 and 6, respectively. It communicates with the front and back via the.

  Thus, the non-slip covers 3 and 3 formed on the grips 1 and 1 are filled with the small through holes 4, 4, 5, 6 and 6 near the upper part, the lower part and the middle part. The front and back surfaces are firmly integrated with each other. Therefore, even if a force is applied in the direction in which the covers 3 and 3 are pulled out during the operation, even if cracks occur due to fraying or deterioration with time, the grips 1 and 1 will not come out. Of course, it does not come off from the upper position.

  In the above embodiment, the gardening scissors have been described. However, the present invention can be widely used for a manual instrument / tool having a non-slip cover. Further, the material of the blade part 7, the handle 1 and the anti-slip cover 3 shown above, the covering forming means of the anti-slip cover 3, the position and number of the small through holes 5 and 6, etc. are examples, and It is not limited.

It is a perspective view which shows the Example which used this invention for the grip handle of gardening scissors. It is a partially cutaway front view of the principal part of what was shown in FIG. It is the II sectional view taken on the line in FIG. It is a perspective view which shows the state where the anti-slip cover was peeled off by the handle of the conventional gardening scissors.
