1. Field of the Invention
The present invention relates to a handle, and more particularly to a toolbox handle.
2. Description of the Prior Art
Conventionally, toolbox handles are made of hard materials to sustain heavy loads, and in order to increase the loading capacity, a radial dimension of the handle is enlarged or the handle has a solid structure. The toolbox handles disclosed in TWI435796, TWM447302 and TWD152976 have the above-mentioned structure. However, this kind of conventional arts focus on higher loading capacity and neglect user's feeling of gripping.
Therefore, TW569890 provides a suitcase handle in which an upper portion and a lower portion of the handle are made of two different materials. The upper portion of the handle is made of a harder material, and the lower portion of the handle is made of a softer material to improve the comfort of gripping. In addition, at least one through hole is disposed between the upper portion and the lower portion to increase air convection, keep the handle dry and prevent odors. However, in this kind of conventional arts, when the lower portion is made of the softer material, the loading capacity of the handle is reduced. The loading capacity is neglected for the pursuit of comfort. Besides, the through holes disposed between the upper and lower portions of the handle cause the upper portion to be too soft and deform easily, and the through holes will close completely to block air convection. After multiple times of use, the lower portion and the upper portion are prone to separate from each other.
The present invention is, therefore, arisen to obviate or at least mitigate the above-mentioned disadvantages.
The main object of the present invention is to provide a toolbox handle which gives a user a comfortable feeling of gripping and has preferable loading capacity and air convection.
To achieve the above and other objects, the toolbox handle of the present invention includes a connecting portion and a grip portion. The connecting portion is provided for being connected to a tool box. The grip portion and the connecting portion are mutually connected, and the grip portion has a circumferential side for gripping. The circumferential side is formed with at least one through hole. An inner circumferential face of each through hole is formed with at least one rib portion, and each through hole is at least partly stepped.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment(s) in accordance with the present invention.

The connecting portion 2 is provided for being connected to a tool box 6. In this embodiment, the connecting portion 2 can be disposed at two ends of the toolbox handle 1 respectively or disposed at only an end, but a number of the connecting portion 2 is not limited thereto. The grip portion 3 and the connecting portion 2 are mutually connected, and the grip portion 3 has a circumferential side 31 for gripping. The circumferential side 31 is formed with at least one through hole 32. An inner circumferential face 321 of each through hole 32 is formed with at least one rib portion 33, and each through hole 32 is at least partly stepped.
In addition, the circumferential side 31 partly covers the grip portion 3, and a disposing direction along which each through hole 32 runs through the grip portion is substantially perpendicular to an extension direction of the grip portion 3. Each through hole 32 is deformable; therefore, when the grip portion 3 receives a force, each through hole 32 deforms to reduce vibration; and when the user grips the toolbox handle 1, s/he will not think the grip portion 3 is hard and uncomfortable to grip. Hence, the deformability of the grip portion 3 can be controlled through adjusting a number or a dimension of the at least one through hole 32 to provide the user with comfortable feeling of gripping and allow air to flow through each through hole 32 to keep the grip portion 3 dry. Preferably, in view along the disposing direction, the at least one through hole 32 is symmetrically disposed relative to a center of the grip portion 3 to share a force averagely and to prevent the force from concentrating on a place and each through hole 32 from partly deforming. In this embodiment, the grip portion 3 is averagely formed with four the through holes 32; however, the number or dimension of each through hole 32 are changeable in accordance with different applications.
The four through holes 32 allow the grip portion 3 to partly deform to provide the user with comfortable feeling of gripping, and each rib portion 33 prevents the four through holes 32 from overly deforming or closing and allows the toolbox handle 1 to have enough supporting capacity to sustain a weight of the tool box 6. Therefore, the toolbox handle 1 can provide the user with comfortable feeling of gripping and serve the function of weight loading. It is to be noted that each rib portion 33 and the inner circumferential face 321 can be constructed in a multi-tiered structure or may be constructed in any other structure in accordance with various requirements and/or materials.
Preferably, the grip portion 3 has an upper portion 11 and a lower portion 12 which is formed with the four through holes 32, and an outer surface of the upper portion 11 is formed with at least one recessed portion 111. Relative to the through holes 32, the at least one recessed portion 111 is at least partly disposed between every two of the through holes 32. In this embodiment, three the recessed portions 111 are disposed on the outer surface of the upper portion 11 equidistantly. When the user grips the toolbox handle 1, his/her palm partly slightly comes into the three recessed portions 111 to make the grip portion 3 contact with his/her palm tightly, increase the contact area of the grip portion 3 and his/her palm and improve the stability of gripping. When the user grips an object, his/her fingers sustain more loads and may feel hurt and uncomfortable easily; therefore, the four through holes 32 are arranged on the lower portion 12 to allow the lower portion 12 to deform and further to make the user's fingers feel more comfortable. Preferably, the lower portion 12 is greater than the upper portion 11 in curvature, and the curvatures of the lower portion 12 and upper portion 11 correspond to the radians of the user's palm and fingers respectively so as to make the user feel more comfortable when gripping the toolbox handle 1.
In addition, an engaging portion 21 is disposed on the connecting portion 2, and the engaging portion 21 is detachably assembled to the tool box 6. When the toolbox handle 1 is damaged, the user only needs to repair the toolbox handle 1 instead of the whole tool box 6. In this embodiment, the engaging portion 21 is cylindrical to allow the toolbox handle 1 to rotate relative to the tool box 6. Furthermore, a marking portion 51 for marking is arranged on the grip portion 3 to allow the user to find the object s/he needs quickly.

Given the above, on the premise that the toolbox handle of the present invention aims to carry heavy objects, a plurality of through holes are disposed on the grip portion to allow the grip portion to deform, provide the user with comfortable feeling of gripping and keep the grip portion dry. In addition, the inner circumferential face of each through hole is formed with the rib portion to prevent the through hole from overly deforming; therefore, even if the toolbox handle is made of a softer material, each rib allows the toolbox handle to maintain the supporting capability to sustain the weight of the tool box. The toolbox handle of the present invention provides the user with preferable feeling of gripping and loading ability.
Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
