The present invention relates generally to a ratchet wrench tool set, and more particularly to a ratchet wrench tool set featuring a greatly reduced size and improved integration and easy use.
A conventional ratchet wrench tool set comprises a ratchet wrench and also comprises a plurality of tool bits and a toolbox that receives and holds the ratchet wrench and the tool bits.
However, the ratchet wrench is made up of a ratcheting head and a handle connected to the ratcheting head. Inevitably, the size of the toolbox that receives and holds the ratchet wrench must be bulky.
For a bicycle rider, when doing exercise or working out by riding a bicycle, he or she will encounter certain malfunction issues of the bicycle. Disassembling and/or repairing is often necessary to be conducted on site. For such a reason, bicycle riders may carry a ratchet wrench tool set. However, the large size of the ratchet wrench tool set causes a problem for carrying and sometimes, the function provided thereby may not be sufficient so that additional chain remover or inflation can must be carried, this being an additional problem.
To overcome the problems that the conventional ratchet wrench tool set has a relatively large size, is not easy to carry, and may not have sufficient functions, the present invention aims to provide a ratchet wrench tool set, which generally comprises a box, which defines therein a receiving space; a plurality of tool bits, which are removably received in the receiving space of the box; two side boards, which are respectively mounted to two opposite sides of the box, each of the side boards having an inside surface in which a slide groove is formed; a ratcheting device, which comprises a rotary connection plate and a ratcheting head mounted to the rotary connection plate, the rotary connection plate being rotatably coupled to front ends of the two side boards to be reciprocally rotatable between an operation position and a storage position, the rotary connection plate comprising a constraint step section thereon; and a slidable constraint cover, which has a front end comprising a constraint projection section formed thereon and two opposite sides each comprising a slide protrusion formed thereon, the slide protrusions being respectively and slidably received in the slide grooves of the two side boards to allow the slidable constraint cover to move frontwards and rearwards through sliding along the slide grooves. When the slidable constraint cover is moved frontwards through sliding, the constraint projection section engages the constraint step section of the ratcheting device to retain the ratcheting device in the operation position. When the slidable constraint cover is moved rearwards through sliding, the constraint projection section disengages from the constraint step section to allow the ratcheting device to rotate to the storage position. The present invention helps improves the functionality and convenience and also help reduces the overall size for easy carrying.
The foregoing objectives and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.
Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.
The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.

The above provides a description of the constituent components of a ratchet wrench tool set 100 according to a preferred embodiment of the present invention and assembling thereof. An operation and use of the present invention will be described as follows:
To store or carry out the present invention, the slidable constraint cover 70 is first moved, through sliding, in the rearward direction (as shown in
To use the ratcheting head 52 of the present invention to wrench or rotate an object, the slidable constraint cover 70 is first moved rearwards through sliding and then, the ratcheting device 50 is rotated upward to an operation position. Subsequently, the slidable constraint cover 70 is moved frontwards through sliding to have the constraint projection section 71 of the slidable constraint cover 70 engages with the constraint step section 512 of the ratcheting device 50 so as to retain the ratcheting device 50 in position to facilitate wrenching of the object.
Further, according to the present invention, the ratcheting head 52 may be a bi-directional ratcheting mechanism, wherein through switching of a switch lever 522 arranged on the ratcheting head 52 (as shown in
Further, although in the above-described embodiment, the first positioning sections of the box are raised blocks and the second positioning sections of the side boards are recesses, it is also feasible to make the first positioning sections of the box recesses and the second positioning sections of the side boards raised block, where the same effect of coupling and positioning can also be achieved.
In an embodiment of the present invention, as shown in
The present invention provides an arrangement that combines a ratcheting device, a toolbox, tool bits, a chain tool, and a seat for inflation canister together, providing easiness of carrying and also providing complete functions of repairing and maintenance. The present invention also allows the ratcheting device to be rotated for folding to a storage position in order to reduce the overall length to enhance carrying thereof.
It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.
While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the claims of the present invention.
