Description

  The present invention relates to a tool having a grip portion, and more particularly to a grip portion having a three-dimensional structure in which a finger can be inserted from a plurality of directions.

  The shape of the handle of the tool that is sandwiched between two tips, such as scissors, forceps, and pliers, is such that there is a ring and a finger is passed through them, or a rod-like object is gripped. When both are rings, the tip can be opened and closed with only a human finger, but when either or both are rod-shaped, the tip is opened by the reaction force of the spring and the force that overcomes it is generated by the finger. Is to close. The present invention relates to the shape of the handle of such a tool.

  To list the background art, Patent Document 1 is such that the blade edge and the handle portion of a surgical scissors are angled with respect to the surface formed when the scissors are opened. Patent Document 2 adjusts the position of two rings through which fingers pass through a rotating shaft whose direction is the same as that of the rotating part on a plane that can be opened when the main body is opened around the rotating part with a hand tool such as a pliers. It is a possible structure. Patent Document 3 is a hairdressing scissor in which the position of the thumb ring of two rings is variable. Patent Document 4 is a scissors that enable more accurate and sharp shearing by matching the shape of a ring portion or the like to the structure of a human finger.

  Some of the prior art documents change the position of the ring for ease of use. In Patent Document 1, the change is made in a direction orthogonal to the plane made of the ring, and in Patent Document 2 on the plane made of the ring. Is limited. In Patent Document 3, the position of each of the two rings with respect to the main body can be adjusted in a plurality of directions by a combination of a sliding portion and screwing, but is limited to parallel movement. In Patent Document 4, an angle is provided on the contact surface of the ring with the finger, but the relative positional relationship between the main body and the ring is defined on the same plane. In Patent Document 5, the position of the wheel cannot be changed.

  In the background art, the ring for inserting the thumb, the index finger, the middle finger, or the ring finger is limited to one each, and the position is limited to one position at the time of use. That is, since the way of holding is limited to one way, when the orientation of the tip portion required for the work changes variously, the user is burdened to adjust the wrist or arm posture each time. In addition, the shape of the ring is constant regardless of the left and right hands, or is made to match either one, so that depending on the hand used, the burden increases or pain develops.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a tool having a grip portion that does not require an adjustment mechanism and can be held by changing the orientation of the tip without changing the posture of the wrist. To do.

  As a result of intensive studies to solve the above-mentioned problems, the inventors of the present invention configured the grip portion to be composed of two annular members, the central axes of the two annular members substantially overlap, and a gap between the two annular members. It has been found that it is possible to provide a tool that has a gripping part that can be held by changing the orientation of the tip without changing the posture of the wrist, without requiring an adjustment mechanism, and has led to the completion of the present invention. .

  And according to one aspect of the present invention, a tool having a gripping portion, the gripping portion is composed of at least two annular members, and the central axes of the two annular members substantially overlap with each other. It is characterized by having a gap between them.

  Further, it is desirable that the two annular members have a bent portion at the end on the side opposite to the tool, and the bent portion reduces the gap.

  Furthermore, it is desirable to have a beam connecting between the ends of the two annular members on the side opposite to the tool.

  Furthermore, it is desirable to provide an opening through which at least one finger can be inserted into the annular member.

  Furthermore, it is desirable to insert at least one finger into the gap.

  Furthermore, it is desirable that there are two gripping portions.

  Furthermore, it is desirable that the tool is scissors, forceps, and pliers.

  According to the present invention, the gripping portion is configured by two annular members, the center axes of the two annular members are substantially overlapped, and a clearance is provided between the two annular members, and no adjustment mechanism is required. There is an advantage that it is possible to provide a tool having a grip portion that can be held by changing the orientation of the tip without changing the posture of the wrist.

It is a three-view figure of the tool which has a holding part concerning an embodiment. It is the diagonal front view and diagonal back view of the tool which has a holding part concerning an embodiment. It is a figure which shows the various usage forms of the tool which has a holding part. Example 1 It is a figure which shows the other tool from which the structure of a holding part differs. (Example 2) It is a figure which shows the other tool from which the structure of a holding part differs. (Example 3)

  Hereinafter, embodiments of the present invention will be described. The scope of the present invention is not limited to these descriptions, and other than the following examples, the scope of the present invention can be appropriately changed and implemented without departing from the spirit of the present invention.

  FIG. 1 is a three-side view (plan view, front view, side view) of a tool having a gripping portion of the present invention. As shown in FIG. 1, the tool 1 is scissors, and is configured to be able to sandwich and cut an object with a tip. The method of opening and closing the tip is the same as that of the conventional scissors, and it can be performed only with a human finger by inserting a finger into the grip portion (2 to 6).

  The scissors in FIG. 1 are different from the conventional scissors in the configuration of the gripping portions (2 to 6). The gripping portion is composed of annular members (2a and 2c, 2b and 2d), and the central axes of the openings 5a of the two annular members (2a and 2c) are substantially overlapped and a gap between the two annular members. 6a, and the central axes of the openings 5b of the other two annular members (2b and 2d) are also substantially overlapped and have a gap 6b between the two annular members. Moreover, the bending part 4 has the structure which has the bending part 4 in the edge part on the opposite tool side of one and the other two annular members, and makes a clearance gap (6a and 6b) small. The beam 3 is configured to connect the ends of the two annular members on the side opposite to the tool.

  In addition, although each center axis | shaft of the two annular members is the structure which overlaps substantially, here, "substantially overlaps" is a thing of the grade which can be considered that it overlaps of course, although it overlaps completely. Means including errors. More specifically, for example, when the openings (5a, 5b) are substantially rectangular, an error of about ± 10% of the long side is acceptable, and when the opening is substantially ellipse, an error of about ± 10% of the long diameter is acceptable. The term “substantially overlaps” is the same when used in other elements of this specification.

  In the present embodiment, the bent portion 4 is not limited in shape as long as it has a function of reducing the gap, but is preferably a straight line, a part of an ellipse, or a part of a circle. . In addition, when providing the beam 3, it is not necessary to provide a bending part. Further, by providing the bent portion, the gap is reduced, and the beam may not be provided as long as the finger does not pass through the gap. Furthermore, although the annular members (2a and 2c, 2b and 2d) are provided substantially in parallel, the bent portion is provided so that the gap between the end portions on the side opposite to the tool is narrowed, that is, the annular member is provided non-parallel. There is an advantage that both the beam and the beam need not be provided.

  FIG. 2 is an oblique front view and an oblique rear view of the scissors of the present invention. The openings (5a, 5b) and the gaps (6a, 6b) are sized so that at least one finger can be inserted.

  In the present embodiment, scissors have been described as a tool having a gripping portion, but other tools may be used as long as the gripping portion is provided, and forceps, pliers, etc. are preferable examples.

  Moreover, in this embodiment, although illustrated about the structure which has two holding parts (The holding part which has the clearance gap 6a, and the holding part which has the clearance gap 6b), a holding part, such as a comb and a toothbrush, is one tool. Adopting a gripping part is also a preferable example. Further, the gripping part of the present invention may be adopted as one of the two gripping parts, and the conventional gripping part may be adopted as the other.

  Embodiments of the present invention will be described below. However, the embodiment of the present invention is not limited to the present embodiment, and various uses and shapes of the present embodiment can be implemented.

  FIG. 3 is a diagram illustrating various usage forms of a tool (scissors) having a gripping portion as the first embodiment. (A) shows a usage pattern in which the thumb, index finger, and middle finger are inserted from the openings (5a, 5b). (B) shows a usage pattern in which the thumb, ring finger, and little finger are inserted from the openings (5a, 5b). (C), (d) shows a usage pattern in which the thumb / middle finger is inserted from the openings (5a, 5b). (E) shows a usage pattern in which the thumb is inserted from the side to the scissors. (F) shows a usage pattern in which the thumb is inserted obliquely with respect to the scissors. (G) shows a usage pattern in which a thumb is inserted parallel to the scissors. (H) shows a usage pattern in which a finger is inserted in a direction perpendicular to the scissors. (I) shows a usage pattern in which a finger is inserted in a direction parallel to the scissors.

  As described above, as shown in the first embodiment, the posture of the wrist is provided by providing the grip portion having two annular members, the central axes of the two annular members substantially overlapping and having a gap between the two annular members. You can change the direction of the tip of the tool (scissors) without changing the position. In addition, since an adjustment mechanism is unnecessary, there is no need to adjust each time it is changed. Furthermore, since the shape of the ring is vertically and horizontally symmetrical, it does not matter to the dominant hand. In addition, since the finger can be inserted by various methods, there is an advantage that it is possible to cope with various holding methods and a wide range of hand sizes.

  FIG. 4 is a diagram illustrating another tool having a different gripping portion configuration as the second embodiment. Each gripping part is composed of a single wire, so no beam is provided. And the minimum value of the clearance gap formed by the bending part which opposes is set to the value which a finger does not pass.

  Also in the configuration of the second embodiment, two annular members are equivalently formed by one wire, and the center portions of the two annular members substantially overlap with each other, and there is a gap between the two annular members. Can be configured. And it has the same effect as Example 1. In addition, since the minimum value of the gap formed by the opposing bent parts is set to a value that the finger does not pass through, when opening the cutting edge of the scissors, the finger passes through the gap and moves out of the gripping part. Can be prevented.

  FIG. 5 is a diagram illustrating another tool having a different gripping portion configuration as the third embodiment. Of the two gripping portions, one gripping portion is the gripping portion of the present invention, and the other gripping portion is a conventional gripping portion configured by one annular member. Other configurations are the same as those of the first embodiment.

  Even in the configuration of the third embodiment described above, one gripping portion which is the gripping portion of the present invention has the same effect as the first embodiment, and the other gripping portion can be simply configured with one annular member. There is an advantage that the entire tool can be reduced in cost.

  The present invention does not require an adjustment mechanism, and has industrial applicability as a tool having a grip portion that can be held by changing the orientation of the tip without changing the posture of the wrist.
