【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In the figure, the support 1 comprises a rod-shaped support 2 having an elliptical cross section, a gripping mechanism 3 of an umbrella handle provided at the upper end of the support 2, and a handle attachment mechanism 4 at the lower end of the support 2. In FIG. 1 showing the details of the gripping mechanism 3 of the umbrella handle, a connecting plate 5 is fixed to the tip of the support column 2 by a bolt 6, and the connecting plate 5 has a dogleg-shaped first holding portion 9 at one end. A receiving member 8 having a bent end portion 7 bent at a right angle is fixed to the other end. Further, on the opposite side of the receiving member 8, a swinging member 11 having a curved second holding portion 10 facing the first holding portion 9 is arranged. The rocking member 11 has a pair of projecting pieces 11a, 11a projecting substantially in the center thereof, and the projecting pieces 11a, 11a project vertically from the substantially center of the receiving member 8 and are bent at a right angle to the rocking member side. The swing member 11 is swingably attached to the receiving member 8 by being pivotally attached to the bent ends 8a, 8a by the pin 12. Further, a coil spring 13 is wound around the pin 12 so as to apply an urging force that constantly presses the end 11b of the swinging member 11 against the bent end 7 of the receiving member 8. On the other hand, a disk 15 at the head of the fixed lever 14 is rotatably fixed to the bent end 7 of the receiving member 8 by a pin 16. The pivotal position of the pin 16 on the disc 15 is eccentric, and when the fixing lever 14 is pushed upward vertically, the amount of protrusion of the end of the disc 15 from the bent end 7 to the swing member 11 side. Is the smallest, and when pushed down, the amount of protrusion is maximum.

As shown in FIG. 2, the handle mounting mechanism 4 at the lower end of the support column has a mounting hole 21 for the support column 2 and a slide part 20 vertically divided by a slit 22 continuous to the mounting hole 21, and the slide part 20. It comprises a forked portion 19 extended to the end and a pair of clamp portions 23, 23 provided at respective tips of the forked portion 19. The center end of the slide part 20 can be tightened by a tightening bolt 24 and an operating screw 25, and the support column 2 can be inserted through the mounting hole 21 and slid to an arbitrary position to fix the mounting mechanism 4 at the position. The clamps 23, 23 are tightening frames 26, 26 each having a semicircular portion 26a that matches the outer circumference of the bicycle handle, and the tightening frames 26 facing each other, and also having semicircular portions 27a. It is composed of frames 27, 27, and the fastening frames 26, 26 extend integrally with the forked portion 19. Further, bolt holes 28, 28 ... Are provided at the upper and lower ends of each tightening frame 26, 27. By means of bolts 29, 29 and nuts 30, 30 inserted into the bolt holes 28, 28 from the tightening frames 27, 27 side. The fastening frames 27, 27 are integrally fixed to the fastening frames 26, 26.

In the support tool configured as described above, first, the bolts 29 and the nut 30 of the clamp portions 23, 23 are removed, and the tightening frames 26, 26 on the main body side are moved from the front of the bicycle to an arbitrary position of the handle M. The handle M is fitted to the semicircular portions 26a, 26a. Then, the tightening frames 27, 27 are fitted to the handle M from the opposite side and tightened by the bolts 29, nuts 30, the handle M is firmly clamped by the clamp portions 23, 23 as shown in FIG. Then, when the fixing lever 14 of the gripping mechanism 3 of the umbrella handle is pushed upward, the amount of protrusion of the end of the disk 15 from the bent end 7 is minimized, and at the same time, the swinging member 11 causes the pin 12 to serve as a spindle and the coil spring 13 to move. The end portion 11b approaches the bent end portion 7 and the second holding portion 10 separates from the first holding portion 9, and the distance between both holding portions is increased as shown in FIG. 3 (A). . Therefore, the handle T of the umbrella can be inserted between the first and second holding portions. After that, when the fixed lever 14 is pulled down, the protruding amount of the rotating disk 15 end portion gradually increases and presses the end portion 11b to tilt the swinging member 11 in the opposite manner to the second holding portion. By pressing 10 toward the first holding portion 9 side, the grip T can be firmly held by both holding portions as shown in FIGS. 3 (B) and 4. If necessary, the grip position of the support column 2 can be adjusted by the operation screw 25 of the slide portion 20 to appropriately change the height of the umbrella. As described above, according to the present embodiment, since the support pillar can be supported by the two clamp portions 23, 23, a high mounting strength can be obtained, and at the same time, a two-piece type tightening frame for holding the outer circumference of the handle can be provided. Depending on the configuration, it can be fixed not only at the center of the handle but also at any position, and the angle can be freely changed back and forth.

In the above-described embodiment, the clamp portion is provided with the two separate tightening frames 26 and 27, but the tightening frames 26 and 27 may be connected by using a hinge. Also, if the bolts for fixing the tightening frame are thumbscrews, no tools are required, and the angle and position can be changed more easily. Further, the structure of the holding mechanism at the upper end of the column and the structure of the slide portion are not limited to those in the above embodiment, and the design can be arbitrarily changed without departing from the gist of the present invention.

[0010]

[Effect of device]

 As described above, according to the present invention, the attachment strength between the support and the bicycle handle is high, and the reliability at the time of attachment is also high. In addition, since the mounting position and angle of the handle can be changed arbitrarily, the support does not interfere with the function of the umbrella. In particular, since the mounting position can be changed, it can be suitably applied to a so-called sports type steering wheel that is straight, and the types of bicycles that can be used are expanded.
