## Background
FIELD OF INVENTION
The present invention relates to a bicycle and, more particularly, to a collapsible stand for a bicycle.
BACKGROUND OF INVENTION
FIG. 5 shows a conventional stand 10 for a bicycle. The conventional stand 10 includes a palming portion 12, a hooking portion 14 extending upwards from the palming portion 12 and two legs 16 extending downwards from the palming portion 12. In use, the hooking portion 14 hooks the down tube of the bicycle. The palming portion 12 palms the bottom bracket of the bicycle. The legs 16 cooperate with the front wheel in order to provide three-point support. The stand 10 is non-collapsible. It occupies a certain space, in use or not. Hence, it is inconvenient for a rider to carry the stand 10.
The present invention is therefore intended to obviate or at least alleviate the problems encountered in the prior art.
SUMMARY OF INVENTION
The primary objective of the present invention is to provide a collapsible stand that is small in size and light in weight.
According to the present invention, a collapsible stand includes a hooking element for hooking a down tube of a bicycle. An upper palming element is pivotally connected with the hooking element for palming a bottom bracket of the bicycle. A lower palming element is pivotally connected with the upper palming element for palming the bottom bracket. A telescopic device is connected with the lower palming element. Two legs are pivotally connected with the telescopic device for cooperating with the front wheel in order to form a three-point supporting situation.
Other objectives, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the attached drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
FIG. 1 shows a collapsible stand according to the preferred embodiment of the present invention in a collapsed mode.
Referring to FIG. 2, the collapsible stand includes a propping and supporting element or device 80 and a holding device 90 pivotally connected with the propping device 80. The propping device 80 is in the form of a longish support member having first and second ends. The propping device 80 includes a telescopic device (not numbered) consisting of a tube 81 and a rod 82 inserted in the tube 81. The tube 81 defines a space 87 and a slot 88 communicated with the space 87. The rod 82 is movably inserted in the space 87. A knob 83 is secured to an end of a screw (not shown). An opposite end of the screw is driven into a screw hole (not numbered) defined in the rod 82 through the slot 88.
Ends of first and second legs 54 are pivotally connected about leg pivot axes with the rod 82 at the first end of the propping device 80. The propping device 80 is located intermediate the first and second legs 54. The first and second legs 54 are pivotal between a collapsed position generally parallel to each other and to the propping device 80 and a fully extended position extending at a nonparallel angle to each other and to the propping device 80. The leg pivot axes are located in a plane.
A lower palming element 85 is secured to the tube 81. The lower palming element 85 includes two ears 55 formed thereon and at the second end of the propping device 80. A pad 59 (FIGS. 1 and 3) is attached to each of the ears 55.
The holding device 90 includes an upper palming element 91 pivotally connected about a device pivot axis parallel to the plane of the leg pivot axes, with the lower palming element 85 being at the second end of the propping device 80. Thus, the holding device 90 is collapsible with the dropping device 80. The holding device 90 further includes a hooking element 93 pivotally connected about a hook pivot axis with the upper palming element 91, with the hook pivot axis being perpendicular to the device pivot axis and to the propping device 80. The upper palming element 91 includes an ear 94 formed at an end and an ear 98 formed at an opposite end. The ear 94 is located between the ears 55. A bolt 95 is driven into the ears 94 and 55 in order to pivotally connect the upper palming element 91 with the lower palming element 85. Two pads 96 are attached to the upper palming element 91. The hooking element 93 includes two cars 92 formed at an end. A screw (not numbered) is driven into the ears 92 and 98 in order to pivotally connect the hooking element 93 with the upper palming element 91.
A spacing between the first and second ends of the propping device 80 is variable, with the device pivot axis being perpendicular to the spacing. The legs 54 have a length from the leg pivot axes generally equal to but slightly less than the spacing to the device pivot axis when the propping device 80 is telescoped together.
Referring to FIG. 3, the stand is in a fully extended position. FIG. 4 shows the fully extended collapsible stand supporting a bicycle 60. The bicycle 60 will not be described in detail for being conventional. A down tube 62 of the bicycle 60 is supported on the pads 59 and 96 of the collapsible stand. A tube of the bicycle 60 that receives a crank axle of the bicycle 60 is hooked by the hooking element 93. A front wheel 64 of the bicycle 60 and the legs 54 form a stable three-point supporting condition. Thus, the bicycle 60 is kept in a stable situation.
The present invention has been described through detailed illustration of the preferred embodiment. Those skilled in the art can derive variation 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.
