Title: Bicycle tool set

Description:
FIELD OF THE INVENTION 
     The present invention relates generally to a bicycle accessory, and more particularly to a bicycle tool set for fixing the bicycle. 
     BACKGROUND OF THE INVENTION 
     The U.S. Pat. No. 6,044,508 discloses a bicycle tool set comprising a first tool member and a second tool member, which are detachably fastened together. The second tool member is provided with three positioning grooves for retaining some hand tools, such as hexagonal wrenches. The first and the second tool members are held together by a protrusion and a recess in which the protrusion is received. The protrusion is not securely received in the recess, thereby making the first tool member and the second tool member susceptible to separation from each other inadvertently. 
     SUMMARY OF THE INVENTION 
     The primary objective of the present invention is to provide a bicycle tool set with a means to hold together securely the tool members of the bicycle tool set. 
     In keeping with the principle of the present invention, the foregoing objective of the present invention is attained by the bicycle tool set comprising a first tool member and a second tool member. The two tool members are securely held together by a tenon and a mortise such that the two tool members are rotated an angle to locate securely. The second tool member is provided with a plurality of fixation holes for fixing a plurality of hand tools. 
     The features and the advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings.

     DETAILED DESCRIPTION OF THE INVENTION 
     As shown in FIG. 1, a bicycle tool set embodied in the present invention comprises a first tool member  10  and a second tool member  20 . 
     The first tool member  10  is of a long platelike construction and is provided in the midsegment with a pivoting slot  11  which is provided in the bottom wall with a tenon  12 . The tenon  12  is provided with a pillar  121  having a round cross section, and with a retaining portion  122  of a long platelike construction. The retaining portion  122  is located at the outer end of the pillar  121  such that the longitudinal axis of the retaining portion  122  is perpendicular to the longitudinal axis of the first tool member  10 . The first tool member  10  is further provided in one side with a locating member  13  which is in turn provided with a retaining portion  131  and a recess  132 . The first tool member  10  is still further provided at one end with a tire removing end  14  and a tire deflating device  15 . 
     The second tool member  20  is of a long platelike construction and is provided with a pivoting projection  21  corresponding to the pivoting slot  11  of the first tool member  10 . The pivoting projection  21  is provided with a mortise opening  22  corresponding in shape and location to the retaining portion  122  of tenon  12  of the first tool member  10 . The length of tenon  12  is greater than the depth of the mortise opening  22 , so as to permit retaining portion  122  to engage the second tool member  20  below walls of mortise opening  22  as shown in FIG.  7 . The longitudinal direction of the cross section of the mortise opening  22  is parallel to the longitudinal direction of the second tool member  20 . The second tool member  20  has a planiform end  23  serving as a screwdriver. The second tool member  20  is provided in one side thereof with a polygonal hole  24 , and at the end edge of other side thereof with two polygonal notches  25  and  26 . The second tool member  20  can thus be used as a wrench. The pivoting projection  21  is provided with a protruded portion  27  which is in turn provided with three locating holes  271 ,  272 , and  273 , for locating three hexagonal wrenches  31 ,  32 , and  33  of various specifications. 
     As shown in FIGS. 2 and 3, the first tool member  10  and the second tool member  20  are held together in a cruciform manner that the tenon  12  of the first tool member  10  is rotatably received in the mortise  22  of the second tool member  20 . As the second tool member  20  is turned clockwise for an angle of 90 degrees in relation to the first tool member  10 , the planiform end  23  of the second tool member  20  is received in the recess  132  of the locating member  13  of the first tool member  10  such that the planiform end  23  of the second tool member  20  is retained by the retaining portion  131  of the locating member  13  and retaining portion  122  is engaged to second tool member  20  below the side walls of mortise opening  22 . As a result, the first tool member  10  and the second tool member  20  are so securely held together that they do not fall apart easily. 
     As shown in FIGS. 4-7, the bicycle tool set of the present invention further comprises a case  40  for containing the bicycle tool set. The case  40  is made of a plastic material and is formed of a housing  41  and a cover  42 . The cover  42  is hinged at one end with the housing  41  by a joint  43  on which the cover  42  can swing and keep the cover  42  with the housing  41 . The cover  42  is provided at other longitudinal end with a retaining piece  441 , which can be caught by a retainer  442  of the housing  41  to be buckled up. The cover  42  is provided in the top surface with a chamber  45  and a lid  46 . The chamber  45  is for keeping the tire repairing pieces (not shown in the drawings) and the lid  46  is for sealing the chamber  45 . The lid  46  is provided at one end with a connection piece  461  which is connected with the cover  42  so as to keep the lid  46  with the cover  42  when the lid  46  is opened. The housing  41  is provided in the underside with a locating seat  47  having a locating slot  471  for locating the bicycle tool set of the present invention on a bicycle.
