Description

1258411 V. INSTRUCTION DESCRIPTION (1) [Technical Field] The present invention relates to a grip reinforcement structure of a wrench, which is mainly for making the grip portion more favorable for the user to hold and strengthen the structural strength thereof, and A wrench grip structure that can be applied to various types of wrench tools. [Prior Art] According to the currently commercially available wrench, it is attached as an accessory (US Patent Publication No. 6257101 "ADJUSTABLE HING E ADJUSTMENT TOOL"), which discloses a conventional wrench, which is a grip portion of most wrenches. The wider surface design is flush with the wider surface of the head; however, the design allows the user to grasp the wide surface of the handle with the entire hand when using the wrench, and the hand finger The joint of the joint is at the end of the grip portion. When the wrench tool is pulled, the force is applied to the joint of the hand, which is mainly the palm of the hand, and then the end faces of the flat grip are Give force. However, in this type of action mode, most of the hand force is absorbed by the finger joints independently, and the force surface of the end is only a small area at the joint of the finger, so after the use, the user There is a redness and pain in the joints, which is not ergonomically designed. For those who use this type of hand tools for a long time, it is more likely to cause long-term use and joint inflammation. In view of the unsatisfactory advantages of the above-mentioned wrenches, the creator deeply feels that it is necessary to improve it. It is researched and improved by the experience of designing and manufacturing such products. After a long period of experiment and revision, The design of this creation can make it more practical and promote the progress of the industry.

1258411 V. INSTRUCTIONS (2) [Contents] The present invention relates to a grip reinforcement structure of a wrench, which mainly comprises a wrench body, the wrench system is composed of a driving portion and a grip portion, wherein the grip portion is The wide portion and the driving portion are staggered in a vertical shape, and the holding portion is provided with a reinforcing portion near the end of the driving portion, and the reinforcing portion is gradually convex from the both ends toward the middle, and has a smooth inclined surface to strengthen the same. Structural strength. As described above, the grip of the present invention is no longer like a conventional wrench when the user holds it, and the force applied is mainly independently received by the finger joint, and is dispersed by the contact surface of the entire finger and the wide surface of the grip. The reaction force after the force is applied, and the thumb can abut against the smooth slope of the reinforcing surface, and the overall grip will feel more comfortable, and the force will not feel pain, so that the design effect is more in line with the human body. The design of engineering. Moreover, the design of the reinforcing portion of the invention not only increases the humanized ergonomic design, but also has the effect of strengthening the strength, so that the grip portion is not twisted and deformed due to long-term use, so as to increase the use of the wrench tool. Life expectancy and its appearance are more beautiful, and it also highlights its value. [Embodiment] The present invention relates to a grip reinforcement structure of a wrench, which is shown in the first figure, which is a preferred embodiment of the present invention, which is applied to an adjustable wrench, the grip reinforcement structure of the wrench It mainly comprises a wrench body (10), the wrench body (10) is composed of a driving portion (1 1 ) and a grip portion (1 2 ), wherein: one end of the driving portion (1 1 ) There are three clip edges, and the other end is provided with a first pivot portion (111), which is arranged at the first pivot portion (111).

1258411 V. INSTRUCTION DESCRIPTION (3) There is a pivot hole (1 1 2 ), and an accommodating space (113) is formed at the middle portion; the grip portion (1 2 ) has a second pivot at one end thereof a portion (1 2 1 ), the second pivot portion (1 2 1 ) is provided with a pivot hole 2 (1 2 2 ), and the lower portion of the second pivot portion (121) is flat and has a wider surface The normal vector direction is the same as the hole 2 (1 2 2 ) direction, and the wide surface is adjacent to the second pivot portion (1 2 1 ) end, and a reinforcing portion (1 3 ) is convexly disposed. The reinforcing portion (13) is gradually convex from the both ends to the middle, and has a smooth inclined surface to strengthen the structural strength.

When assembling, the second pivot portion (1 2 1 ) is placed in the accommodating space (1 1 3 ) of the driving portion (1 1 ), and then pivoted by a pivot (20), at this time, the grip portion (1 2 ) The wider surface is orthogonal to the drive unit (1 1 ) (ie, the connection direction is at right angles to each other) (refer to the second figure, which is the assembled state), so that it can be used. When in use, the force application is based on the wide surface of the grip portion (1 2 ) as the main force application surface, and the end portion of the grip portion (1 2 ) is supplemented;

Further, referring to the third figure, in order to reinforce the structural strength, a reinforcing portion (13) is added, and the reinforcing portion (13) is as described above, and the A-A cross-section is shown in the fourth figure. The grip portion (1 2 ) is not provided with a portion of the reinforcing portion, and the B-B cross-section is shown in the fifth figure. The purpose is that the long-term use of the adjustable wrench must withstand high torque values for a long time, in order to avoid A large deformation occurs, and this reinforcing portion (13) is added to increase the structural strength. When using, please refer to Figure 6 and Figure 7, the adjustable wrench

The driving part (1 l ) can be made at the pivoting position for various axial space constraints. It can still be most advantageous, so that the palm can be held in the grip when the force is applied ( i 2, & 1 mode, and the wider side is applied, and then placed with the thumb: the finger is occupied in the most ergonomic way to hold the 丄 (1 3 ), The area of the force is greatly increased compared with the conventional use, and the 俅 _ _ more comfortable 'also because of the use of the 匕 去 尤 $ $ # # # # # # # # # # # # # # # # # # # # # # # # # # 使用 使用 ' ' In view of the above, in fact, the use of the wrench of the present invention is practical and cost-effective, and the disclosed structural invention also has the "novelty" and should be improved in structure and efficiency. The Patent Law on the patent application for invention patents, and please ask the Bureau to strengthen the structure in the early stage. In the structural design, it is completely in line with the development of the industry. It has an unprecedented innovative structure, and the doubts can be compared with the prior art. The knot is "progressive" and it fully meets the requirements of the application. Set, is said to bring the law review 'and affirmed.
