When a bicycle has to be repaired and maintenance has to be carried out on the bicycle, it has been the practice to invert the bicycle and rest the bicycle on the seat and handlebars while maintenance is carried out on the bicycle.

However, with many of the more modern types of bicycles this is not a practicable consideration, and thus it is difficult to work on the bicycle to 15 remove the wheels, crank arms and crank axle, although it is often possible to repair the crank when the bicycle is inverted.

It is an object of this invention to provide a bicycle stand in which the bicycle is supported in its upright position, so that maintenance can be carried out.

It is a further object of this invention to provide a means including a stand whereby the bicycle may be securely locked in position to prevent theft.

Thus there is provided according to the invention a bicycle stand, the stand 25 having an upright stem extending from a base, the saddle adjustably positioned on the stem to support the bicycle by the housing of the crank arm, and further adjustable clamping hooks to engage the upper and/or lower bars extending from the seat stem to the front of the bicycle.

In order to more fully describe the invention reference will now be made to the accompanying drawings in which: FIG. 1 is a view of the stand, and FIG. 2 shows a portion of the bicycle frame attached to the stand, various portions of the bicycle being omitted for the sake of clarity.

Referring to the drawings, the bicycle stand 1 comprises a base 2 having attached thereto a vertical stem 3, an adjustable sleeve 4 having 0 moo 0 8 0 8 u0 0 o 0 0 o *00000 00 0 0 8o I 3 welded thereto a saddle 5, the sleeve being locked in position by a locking screw 6. The saddle carries an upstanding pin 7, the pin being adapted to engage between the forward portion of the rear forks 8 adjacent the saddle stem 9, so that the saddle carries the weight of the bicycle, with the pin 7, by engaging between the forks, securely locates the bicycle frame, the pin 7 engaging between the forks between the boss of the axle housing for the crank arms, and the bridge which extends between the two rear forks before they diverge to receive the rear wheel.

On the stem 3 there is positioned a second sleeve 10 positioned above the first sleeve, this sleeve 10 having a hook 11 which extends o o upwardly and is adapted to be positioned to engage beneath the lower o bar 12 of the bicycle frame, this sleeve 10 being locked in position by a :00 o 15 locking screw 13.

o Slidably received in the upper portion of the stem 3 is an extension 14 0 00a 0 0 carrying at its upper end a downwardly extending hook 15, the extension being locked in position in the stem 3 by a locking screw 16.

2 Thus it will be seen that to position the bicycle on the stand, the frame of 0000 0o o the bicycle is positioned to engage the pin 7 between the forward 0 00 portion of the rear forks 8, and the second sleeve 10 is then moved upwardly to engage its hook 11 under the lower bar 12 and is then locked in position, and the upper hook 15 is then moved downwardly by moving the extension 14 within the stem 3 to engage the hook 15 over the upper bar 17 of the bicycle frame.

tI In this position the frame is securely positioned on the stand, and then the bicycle can be readily stripped, the wheels removed, and complete maintenance can be carried out on all portions of the bicycle.

While the drawings illustrate the stand carrying a ladies bicycle, it will be seen that by the adjustments it can be adapted to any form of bicycle, and the extension 14 is such that it can be raised to engage over the upper bar of a gents bicycle.

i .i c i 4 For the parking of a ladies or smaller bicycle, the saddle 5 can be adjusted so that the rear wheel is slightly off the ground so that some weight is applied to the stand to steady the base.

Also one or more sleeves 10 with hooks 11 may be provided to engage one or more parts of the frame.

To prevent the sleeve 10 from sliding off the end of the stem 3, a stop may be provided. This may be a weld spot or a small obstruction formed on the end of the stem 3 in case the wing nut or lock 13 is removed.

o 0.

o6 In order to lock the bicycle to the stand, the pin 7 could have a hole drilled therethrough to take a padlock, or alternately it is preferred that *o 0 15 the pin 7 be formed as a loop similar to a hairpin bend to secure the S00o O 0padlock. Of course other forms of locking can be provided.

S000 00 00 In carrying out maintenance of the bicycle, the wheels, handbrakes, gear assembly are easy to repair and adjust when in the normal upright position, and the pedals can be turned for checking the operation of the gear change assembly and the brakes.

0 00 000 Also the stand can be used by a child or learner to sit on the bicycle and learn how to steer, pedal, change gears and brake. The stand would @0 25 be securely located, and further locking bars or hooks can be added to ensure that the bicycle is secure when the learner is seated on the bicycle.

The base can be of any form, and as illustrated it can be formed of two cross members, one of these cross members carrying an adjusting screw at its end so that the stand can be levelled to be thus stable on the surface on which the stand rests. Alternately the base may be a flat plate or other structure to stably support the bicycle.

Alternatively, the base could be circular or any other form of base.

The stand can readily be adapted to provide the locking means on the stand so that the bicycle cannot be removed therefrom by any authorized person, and in this instance, the base and/or the stem 3

A

would be fixedly secured to the ground or other area so that the stand could not be removed therefrom.

In a further form of the invention, where instead of the pin 7 there may be a hook which is rotatable in the saddle to pass between the forks and there be rotated to engage one or both forks. The stem of the hook may pass through the saddle, and be provided with a lock to secure the bicycle.

Also instead of there being one pin 7 there may be a spaced pair of pins to engage the outsides of the forks.

The stems and extension, while being shown of square tubular material o o may also be formed of round material, and can be formed of metal or 00 o 0:00 0 15 any suitable plastics material.

eo 011 S000 In order to protect the paintwork on the bicycle to prevent scratching 00 0, 0 a 0 thereof, suitable pads or the like can be positioned adjacent the sleeves and extensions and stem to prevent scratching thereof, these preferably being rubber or the like and also the hooks themselves can be formed of a material which is not liable to scratch the paintwork.

00 0 ueo 00 1 Although one form of the invention has been described in some detail it is to be realized that the invention is not to be limited thereto but can 00 o.-d 25 include various modifications falling within the spirit and scope of the invention.
