Description

Grip structure that can be used by left and right hands

The invention relates to a grip structure, and in particular to a grip structure that can be used by left and right hands.

The common hand tools (such as saws) are mainly operated by the user with the hand. In order to improve the user's control effect, the end of the hand tool usually has an ergonomic grip structure for use. The person can fully grasp and facilitate the force.

However, in the conventional technology, in order to match the habits of different users, the relevant operators must manufacture two different grip structures suitable for the left and right hands in order to meet the needs of the users, but this will inevitably increase the manufacturing cost. Therefore, some manufacturers have created a grip structure that allows left and right hands to be shared for cost considerations. However, this left-right hand sharing structure lacks a good hand feeling, which makes it relatively difficult to apply force.

SUMMARY OF THE INVENTION A primary object of the present invention is to provide a grip structure that can change usage patterns according to a user's dominant hand to increase ease of use, reduce manufacturing costs, and provide a good hand feel.

In order to achieve the above object, the grip structure of the present invention comprises a grip holder and a grip.

It can be seen from the above that when the handle is in the right hand use state with the user with the right hand as the dominant hand, the finger rest portion of the handle is on the same side as the first side of the handle seat, if the handle is When the user with the left hand as the dominant hand is in the left-hand use state, the finger rest portion of the handle is on the same side as the second side of the handle holder. In other words, the grip structure of the present invention allows the grip to be used in conjunction with the user's dominant hand to increase the ease of use, reduce manufacturing costs, and provide a good hand feel.

More preferably, the finger portion protrudes from the outer circumferential surface of the handle along the first direction, and a gap is formed between the handle and the handle base, and the finger portion of the handle is The arc has an opening that faces the wearing space. Thereby, after the user's palm holds the handle, the thumb abuts against the outer circumferential surface of the handle, and the other four fingers are placed at the opening of the finger resting portion after being placed in the wearing space. This makes it easy to apply force to the grip.

More preferably, the handle base has a body, one end of the seat body has a saw blade fixing groove, and the other end of the seat body extends along the second direction away from the saw blade fixing groove to form a cantilever portion. One end of the handle is detachably disposed at an end of the cantilever portion. Thereby, the wearing space is formed between the seat body of the handle base, the cantilever portion of the handle seat and the handle.

More preferably, the cantilever portion of the handle holder has a through hole, the handle has a screw hole, and a through hole is formed in the cantilever portion of the handle holder by a fixing member and is screwed to the screw hole of the handle The handle is fixed to the cantilever portion of the handle base.

More preferably, the cantilever portion of the handle holder has a card slot communicating with the through hole, the card slot extending in a direction parallel to the first direction, and the two ends of the handle respectively have an engaging portion, the grip The handle is embedded in the card slot by one of the card portions. Thereby, the grip can be quickly positioned with the grip holder for subsequent fixation, and on the other hand can prevent the grip from rotating during use and affecting the operation.

Detailed construction, features, assembly or use of the grip structure provided by the present invention will be described in the detailed description of the subsequent embodiments. However, it should be understood by those of ordinary skill in the art that the present invention is not limited by the scope of the invention.

Directional descriptions such as "bottom" are merely illustrative terms used in the normal direction of use, and are not intended to limit the scope of claims.

Referring to FIGS. 1 to 3, the grip structure 10 of the present invention includes a grip holder 20 and a grip 30.

The handle base 20 has a first side surface 26 and a second side surface 27 opposite to the first side surface 26. In the normal use state, the first side surface 26 corresponds to the left side of the user, and the second side surface 27 corresponds to the right side of the user. . The handle base 20 has a body 21, and a front end of the base body 21 has a saw blade fixing groove 22 for inserting and fixing a saw blade 12, and the rear end of the seat body 21 is fixed along a second direction D2 toward the blade. The slot 22 extends in the direction of the two opposite cantilever portions 23, and the ends of the two cantilever portions 23 respectively have a through hole 24, and the ends of the two cantilever portions 23 respectively have a latching slot 25 for communicating the through holes 24 on one side opposite to each other. The extending direction of the card slot 25 is parallel to a first direction D1, and the first and second directions D1 and D2 are perpendicular to each other.

The top and bottom ends of the handle 30 respectively have an insertion portion 31 and a screw hole 32 provided in the insertion portion 31. When assembled with the handle holder 20, the handle 30 is firstly engaged by the insertion portion 31 in the first direction D1 in the insertion slot 25 of the cantilever portion 23 of the handle holder 20, and then the two bolts are used. 33 is respectively inserted through the through hole 24 of the cantilever portion 23 of the handle base 20 and screwed into the screw hole 32 of the handle 30. Thus, the fixing of the handle 30 is completed, and at this time, the seat body 21 of the handle holder 20 is gripped. An insertion space 34 is formed between the two cantilever portions 23 of the handle base 20 and the handle 30. As for the removal of the grip 30, the two bolts 33 are removed first, and then the grip 30 can be removed from the grip holder 20 in the first direction D1. In addition, the outer peripheral surface of the handle 30 protrudes from the first direction D1 by a finger portion 35, and the finger portion 35 has an arc shape and has an opening 36 facing the insertion space 34.

As can be seen from the above, if the handle 30 is initially assembled with a user who uses the right hand as the dominant hand, the handle 30 must be assembled with the first side 26 of the handle 20 after assembly (ie, use). The left side of the person is on the same side (as shown in Figures 1 and 3). At this time, the handle 30 is in a right-hand use state P1. If it is replaced by a user who uses the left hand as the dominant hand, it must First, the handle 30 is detached from the handle holder 20, and then the handle 30 is re-assembled upside down and left-right oppositely to the handle holder 20, so that the fingerrest portion 35 of the handle 30 is the same as the handle holder 20 The two side faces 27 (i.e., the right side of the user) are located on the same side (as shown in Figures 4 and 5), and the handle 30 at this time is in a left hand use state P2. However, regardless of which direction the finger rest portion 35 of the grip 30 faces, when the user's palm is holding the grip 30, the thumb abuts against the outer peripheral surface of the grip 30, and the other four fingers are worn in the wearing space. 34 is then placed at the opening 36 of the finger portion 35, so that the force of the handle 30 can be started along the second direction D2, and the handle 30 at this time will drive the handle holder 20 together along the second direction D2. The front and rear actuations allow the saw blade 12 fixed to the grip holder 20 to perform a sawing operation. Further, during the urging of the grip 30, by the engagement between the engaging portion 31 and the insertion groove 25, the rotation of the grip 30 can be prevented from affecting the operation.

On the other hand, the handle holder does not have to be used only in conjunction with the saw blade 12, and the handle holder can also have different structural changes, as shown in Figures 6 to 8, in the second embodiment of the present invention, the handle One end of the seat 40 has a fixing hole 42 for fixing one end of the pipe body 14. The other end of the handle base 40 has a cantilever portion 44. The cantilever portion 44 has a counterbore hole 46 and a communication. The latching hole 48 of the countersunk hole 46 has a bolt hole 54. The handle 50 can fix the cantilever portion 44 of the handle base 40 by a bolt 60. The bolt 60 is inserted through the bolt hole 54 and locked. The nut 62 is disposed in the counterbore 46.

In addition, one end of the handle 50 has a first insertion portion 51, and the other end of the handle 50 has a second insertion portion 52. When the handle 50 is in the right-hand use state P1 as shown in FIG. 6, When the handle 50 faces the user with the right hand as the dominant hand, the handle 50 is inserted into the insertion slot 48 of the cantilever portion 44 of the handle holder 40 by the first insertion portion 51 to complete the positioning. The second insertion portion 52 of the 50 is covered by the end cover 53 so that the handle portion 50 is followed by the first side 41 of the handle holder 40 (ie, the left side of the user) after the assembly is completed. On the same side. Next, if the user with the left hand as the dominant hand is faced, the handle 50 is first detached from the handle holder 40, and then the end cover 53 is removed from the second insertion portion 52 of the handle 50 and then covered. The first engaging portion 51 of the handle 50 is finally repositioned by the second engaging portion 52 to the handle holder 40 by the second inserting portion 52 being reversed upside down and the left and right opposite sides, so that the grip 50 is biased The portion 55 is located on the same side as the second side 43 of the handle holder 40 (i.e., the right side of the user), and the handle 50 is changed to the left-hand use state P2 as shown in FIG.

In summary, the grip structure 10 of the present invention allows the grips 30, 50 to be used in conjunction with the user's dominant hand to change the usage pattern, compared to conventional techniques that can only be operated by a single dominant hand or shared by left and right hands. The invention can effectively improve the convenience of use and provide a good feeling of use, and can also achieve the purpose of reducing the manufacturing cost.
