Title: Tool for skateboards

Description:
BACKGROUND OF INVENTION 
     1. Field of Invention 
     The present invention relates to skateboards and, more particularly, to a tool for skateboards. 
     2. Related Prior Art 
     Skateboards can be used for transportation. Skateboards can be used for sport. Skateboarding is even included in the Olympic games of 2021. Skateboarding is popular among teenagers and young adults. Each skateboard has to be disassembled, maintained and/or repaired and reassembled after it is used for a certain period of time. It requires more multiple tools for such purposes. For example, a wrench, sockets and Allen key/screwdrivers are needed to. However, it is difficult to carry such tools. 
     The present invention is therefore intended to obviate or at least alleviate the problems encountered in the prior art. 
     SUMMARY OF INVENTION 
     It is the primary objective of the present invention to provide a convenient tool for skateboards. 
     To achieve the foregoing objective, the tool is devised for skateboards. The tool includes a grip, an Allen key/screwdriver, a driver and three sockets. The grip includes a non-circular cavity in an end and a groove in a side. The first and second sockets are connected to the grip, opposite to each other. The Allen key/screwdriver is selectively inserted in the groove. The driver is selectively inserted in the cavity. The third socket is formed at an end of the driver. The third socket includes an axial bore, a radial bore, and a cutout opposite to the radial bore. 
     Other objectives, advantages and features of the present invention will be apparent from the following description referring to the attached drawings.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENT 
     Referring to  FIGS.  1  through  5   , a tool is devised for skateboards. The tool includes a handle  10 , a first socket  20 , a second socket  30 , a driver  40 , and an Allen key/screwdriver  50  according to the preferred embodiment of the present invention. The handle  10  includes a grip  11 , two locking plates  12  and  13 , a pawl  14 , and a spring-biased detent  15 . 
     The grip  11  includes a cavity  111 , a groove  112  and a recess  113 . The cavity  111  and the recess  113  are made in two opposite ends of the grip  11 . The cavity  111  is polygonal cavity. The groove  112  is made in a side of the grip  11 . The groove  112  includes two sections  112 A and  112 B extending perpendicular to each other. The section  112 B of the groove  112  transversely extends throughout the grip  11 . The section  112 B of the groove  112  is preferably in a stepped configuration. 
     The locking plates  12  and  13  are substantially identical to each other in shape. The locking plate includes an opening  121 . The locking plate  13  includes an opening  131 . The locking plates  12  and  13  are located on two opposite sides of the grip  11  so that the recess  113  is located between the locking plates  12  and  13 . The locking plates  12  and  13  are connected to the grip  11  by screws and nuts (not numbered). 
     The pawl  14  is located between the locking plates  12  and  13 . The pawl  14  is in adjacent to the recess  113 . 
     The spring-biased detent  15  includes an end inserted in the recess  113  and another end in contact with the pawl  14 . The spring-biased detent  15 , the pawl  14  and the toothed portion  23  of the socket  20  together render the tool a selectively one-way wrench. 
     The socket  20  is inserted in the opening  121  of the locking plate  12 . The socket  20  includes a bore  21 , a mortise  22 , and a toothed portion  23 . The bore  21  and the mortise  22  are made in two opposite ends of the socket  20 . The bore  21  is preferably a hexagonal one corresponding to a head of a threaded bolt or a nut. The mortise  22  is preferably a square one. The toothed portion  23  is formed on the periphery of the socket  20 . The toothed portion  23  of the socket  20  is for engagement with the pawl  14 . 
     The socket  30  is inserted in the opening  131  of the locking plate  13 . The socket  30  includes a bore  31  and a tenon  32 . The bore  31  and the tenon  32  are located at two opposite ends of the socket  30 . The bore  31  is preferably a hexagonal one corresponding to a head of a threaded bolt or a nut. The tenon  32  is a square one inserted in the mortise  22 . Preferably, the bore  31  is in a stepped one including two coaxial sections  31 A and  31 B ( FIG.  7   ). Preferably, the section  31 A of the bore  31  is a hexagonal one corresponding to a head of a threaded bolt or a nut. Preferably, the section  31 B of the bore  31  is a square one. 
     The driver  40  includes a shaft  41 , a socket  42  formed at an end of the shaft  41 , and an insert  41 A formed at another end of the shaft  41 . Selectively, the shaft  41  can be inserted in the cavity  111  of the handle  10  while the socket  42  is located out of the cavity  111 . Selectively, the insert  41 A can be inserted in the section  31 B of the socket  30 . 
     The socket  42  includes an axial bore  42 A, a radial bore  42 B and a cutout  42 C. The axial bore  42 A is made in an end of the socket  42 . The radial bore  42 B and the cutout  42 C are made in two opposite sides of the socket  42 , coaxial with each other. The radial bore  42 B and the cutout  42 C are in communication with the axial bore  42 A. Preferably, each of the axial bore  42 A and the radial bore  42 B is adapted for receiving a head of a threaded bolt or a nut. 
     Selectively, the Allen key/screwdriver  50  can be inserted in the groove  112  of the handle  10 . Preferably, the Allen key/screwdriver  50  is operable to drive a threaded bolt or a screw. 
     Referring to  FIGS.  6  through  8   , the driver  40  is moved from the cavity  111 . The insert  41 A of the driver  40  is inserted in the section  31 B of the bore  31  of the socket  30 . Then, the socket  42  of the driver  40  is used to drive a nut used on a skateboard S. The shaft  41  of the driver  40  is made with an adequate length so that the operation of the handle  10  is not interfered with by other components of the skateboard S. 
     Referring to  FIGS.  9  and  10   , the Allen key/screwdriver  50  is moved from the groove  112  of the handle  10 . The shaft  41  of the driver  40  is inserted in the cavity  111  of the grip  11 . For example, a section of the Allen key/screwdriver  50  is inserted in a bore made in a head of a threaded bolt used on the skateboard S and the axial bore  42 A of the socket  42  of the driver  40  receives a nut used on the skateboard S. Thus, the tool is operable to drive the threaded bolt relative to the nut. 
     Referring to  FIG.  11   , the shaft  41  of the driver  42  is inserted in the cavity  111  of the grip  11 . The radial bore  42 B of the cutout  42 C of the socket  42  receives the threaded bolt used on the skateboard S. Thus, the tool is operable to drive the threaded bolt relative to the skateboard S. 
     Referring to  FIGS.  7 ,  12  and  13   , the bore  21  of the socket  20  and the bore  31  of the socket  30  are operable to receive nuts of different sizes used on the skateboard S. 
     Referring to  FIG.  14   , the pawl  14  is switched between two positions relative to the spring-biased detent  15 . In each of the positons, the handle is suitable to rotate, via the socket  20  or  30 , a threaded bolt or a nut in a direction, but not vice versa. 
     The present invention has been described via the illustration of the preferred embodiment. Those skilled in the art can derive variations from the preferred embodiment without departing from the scope of the present invention. Therefore, the preferred embodiment shall not limit the scope of the present invention defined in the claims.
