BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0015]
In the present invention, as shown in FIGS. 1 and 2, a fork holding rod 9 for detachably holding the tip of the fork 5 of the bicycle 2 is removably placed and fixed on a support means 10 mounted on a tray 8.
[0016]
As shown in FIGS. 3 and 4, the fork holding rod 9 has an elongated central rod 11 having small-diameter portions at both ends, and a cylindrical intermediate rod 12 slidably fitted to an intermediate portion of the central rod 11. A cap 13 and a tightening means 14 which are respectively screwed to screw portions formed at both ends of the center rod 11, and the center rod 11 slides on both sides of the intermediate rod 12 so as to be separated from the center rod 11 by a predetermined distance. One and other cylindrical end rods 15a and 15b freely fitted, and one large-diameter support wheel disposed coaxially with the center rod 11 between the one end rod 15a and the cap 13. 16a, the other large-diameter support wheel 16b disposed coaxially with the center rod 11 between the other end rod 15b and the tightening means 14, and the center rod 11 and its both ends small. Springs 17a and 17b wound around the outer periphery of the small diameter portion of the center rod 11 between the step formed between the portions and the inner surfaces of the flanges formed at the outer ends of the one and other end rods 15a and 15b. The one and other end rods 15a and 15b are always restrained toward the end of the center rod 11 relative to the center rod 11 by the springs 17a and 17b.
[0017]
As shown in FIG. 3, the tightening means 14 is rotatably supported via a eccentric shaft 18 on a small-diameter portion of the center rod 11 protruding outside the other support ring 16b. It comprises a cam disc 19 in contact with the outer surface of the other support wheel 16b, and a tightening arm 20 connected to the cam disc 19 for rotating the cam disc 19.
[0018]
As shown in FIGS. 5 to 7, the support means 10 has a main body frame 21 fixed to the tray 8, and one side extending above the main body frame 21 in a direction orthogonal to the length direction of the tray 8. One of the rod supports 23 pivotally supported at the upper and lower intermediate portions via the pivot pins 22 of the first and second rod supports 23, and the one of the rod supports 23 is restrained in such a direction that the upper portion is always open as shown in FIG. The upper and lower intermediate portions are swingable through a spring 24, a restraining pin 26 of the spring 24, and the other pivot pin 25 extending in the same direction as the one pivot pin 22 on the other upper side of the main body frame 21. And the lever means 28 for swinging the other rod support 27 so that its upper part approaches toward the one rod support 23. It occupies.
[0019]
The one rod support 23 has a curved bottom surface 29 for supporting the lower surface of the intermediate rod 12 of the fork holding rod 9. The curved bottom surface 29 preferably extends over half a circumference. In this way, when a tilting force that rotates in the direction of the tray 8 acts on the intermediate rod 12 placed by the one rod supporter 23 in addition to its own weight when the bicycle tries to fall right and left, When an upward force is applied to one end of the rod support 23 by the intermediate rod 12, a downward force of the same magnitude is applied to the other end of the rod support 23 at the same time. It does not pivot about 22 and thus prevents the intermediate rod 12 from coming off the rod support 23, especially even before the locking means is activated. In addition, a curved side surface 30 is provided on a side surface of the upper portion of the other rod support member 27 facing the one rod support member 23.
[0020]
The lever means 28 has one end connected to the lower part of the other rod support 27 and the other end penetrating the main body frame 21 and projecting to one side of the main body frame 21. A cam plate 33 rotatably supported by a protruding end of the pin 31 via an eccentric shaft 32 and having an outer peripheral surface in contact with the outer surface of the main body frame 21; and a cam plate rotating lever connected to the cam plate 33 34, and a spring 35 wound around the tension pin 31 in order to always keep the upper part of the other rod support 27 in the direction of the one rod support 23.
[0021]
Since the bicycle fork fixing device of the present invention has the above-described configuration, when the bicycle fork fixing device is used, the fork holding rod shown in FIG. 9 is fitted to the intermediate rod 12 and the center rod 11 exposed between the end rods 15a and 15b, respectively, as shown in FIG. The other end rod 15b moves relative to the center rod 11 to the left in FIG. 3 while compressing the other spring 17b, so that the distance between the intermediate rod 12 and the other end rod 15b is reduced. Will be done.
[0022]
At the same time, the one spring 17a is compressed, the distance between the intermediate rod 12 and the one end rod 15a is reduced, and the tip of the fork 5 is fixed to the fork holding rod 9.
[0023]
In this state, the intermediate rod 12 is located at the center of the center rod 11, and if the tightening arm 20 is rotated to loosen the tightening, the one and the other springs 17a and 17b will have one and the other if the strengths are equal. The other end rods 15a, 15b are separated by an equal distance from the intermediate rod 12, so that equal intervals are automatically formed on both sides of the intermediate rod 12.
[0024]
Next, the bicycle 2 having the tip of the fork 5 attached to the fork holding rod 9 is lifted, and the intermediate rod 12 of the fork holding rod 9 is bent as shown in FIGS. It is placed on the bottom surface 29.
[0025]
As a result, the curved bottom surface 29 of one rod support 23 is pushed downward against the spring 24 by the weight of the bicycle 2, and the one rod support 23 rotates about the one pivot pin 22. .
[0026]
In this state, if the turning lever 34 of the lever means 28 is turned and the tension pin 31 is pulled to the left in FIG. 7 against the spring 35, the upper part of the other rod supporting member 27 becomes one of the rod supporting members. 23, and moves the intermediate rod 12 of the fork holding rod 9, whose curved side surface 30 is placed on the curved bottom surface 29 of the one rod support 23, to the one rod support 23. As a result, the one and the other rod supports 23 rotate further, and the intermediate rod 12 is completely held by the curved bottom surface 29 and the curved side surface 30.
[0027]
In the case of a downhill type bicycle, since the fork from which the wheels have been removed is provided with a rod having a diameter of, for example, 20 mm corresponding to the intermediate rod 12 of the fork holding rod 9, the support means 10 has a diameter of this diameter. In this case, the fork of the bicycle 2 can be directly mounted and fixed on the support means 10, and the fork holding rod 9 can be eliminated if unnecessary.
[0028]
In another embodiment of the present invention, as shown in FIG. 7, the lower end of an anti-theft cover 36 which covers the upper surfaces of the one and other rod supports 23 and 27 is connected to the tip of the rotating lever 34 of the lever means 28. A locking means 37 is provided on the cover 36, and a key 39 having a rectangular cross section, for example, is attached to the tip of a locking rod 38 which is rotated by a key operation of the locking means 37. A keyway 40 corresponding to the key 39 is formed as shown in FIG. 5, and the cover 36 is closed as shown in FIG. The frame 20 can be locked.
[0029]
According to this embodiment, the theft of the bicycle 2 and the support means 10 can be prevented.
[0030]
【The invention's effect】
As described above, according to the bicycle fork fixing device of the present invention, when the bicycle 2 is stored, the bicycle fork 5 is fixed to the fork holding rod 9 on the ground, and then lifted together with the bicycle 2 and the fork holding rod 9 is supported by the supporting means 10. It can be placed on the top, making work on the roof of the car extremely easy. Further, the fork holding rod 9 can be used as a temporary placing table on the ground before the bicycle 2 is fixed to the supporting means 10.
[0031]
When the fork 5 of the bicycle 2 is fixed to the fork holding rod 9 on the ground, since the fork holding rod 9 is provided with large-diameter support wheels 16a and 16b, the fork tip and the disc brake caliper can be sufficiently secured from the ground. And can be reliably protected. The support wheel is not limited to a circular plate, but may be a rectangular plate or another support.
