DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to fixing a cargo bag carrier and a rear bumper attached to a rear part of a vehicle body of a riding golf cart.

[0002]

2. Description of the Related Art In a golf course in Japan, a party has a maximum of four golfers and one caddy in total. Accordingly, a five-seater riding golf cart as shown in FIG. 3 is provided, and has a structure in which two people ride on the front seat 6 and three people ride on the rear seat 7. During the golf play, a caddy rides on the driver's seat and a golfer on the other seats of the two-seat front seats 6, and the three-seat rear seats 7 during golf play. In general, three golfers ride and move during golf play.

[0003] The golf cart shown in FIG. 3 has a main frame 1 and a rear frame 2 as a basic structure of a vehicle body, and various components are mounted thereon. The front wheels 4 are steered by the steering wheel 3 during manual driving and by an electromagnetic induction method or a wireless method during automatic driving. Meanwhile, rear frame 2
Is suspended by the rear wheel 5 and is driven by a drive motor (not shown).
Is rotated to drive the riding golf cart. The golf bag 19 is carried on the carrier 9.

The overall length of the above-mentioned five-seater golf cart is generally 3.5 to 4 m. In addition, since the space of the cart store at the golf course is limited, it is important to shorten the overall length of the cart store to store as many riding golf carts as possible in the cart store. Also, at the time of transportation of a riding golf cart, it is desirable from the viewpoint of transportation efficiency to shorten the overall length.

Therefore, a mechanism for folding the carrier 9 and the rear bumper 13 upward in cooperation with each other as shown in FIG. 2 has been studied. However, when traveling on an uneven golf course with the golf bag 19 placed on the carrier 9, the carrier 9 rotates around the carrier fulcrum bearing 14 as a fulcrum,
The problem that the golf bag 19 falls from the carrier 9 was recognized.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to provide a riding golf cart having a mechanism for folding a carrier and a rear bumper upward in cooperation with each other to fix the carrier in use. is there.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the loading platform is locked during use. That is, in the first invention, a riding golf cart including a carrier for loading a golf bag on a rear frame at a rear portion of a vehicle body and a rear bumper, wherein the carrier and the rear bumper have a mechanism for folding upward in cooperation with each other. When the carrier and the rear bumper are not folded, the carrier is locked.

In the second invention, the folding mechanism rotates the rear bumper and the carrier at the same time by a link mechanism using a rod, and the rotation angle of the rear bumper is larger than that of the carrier. The luggage carrier is locked by fixing the frame and the rear bumper using hooks.

In the third invention, the loading platform is attached to the rear frame via a rotatable loading fulcrum bearing, and the rear bumper is attached to the rear frame via a rotatable rear bumping fulcrum bearing. The loading platform and the rear bumper are characterized in that a rotatable loading platform / rod connection bearing attached to the loading platform and a rotatable rear bumper / rod connection bearing attached to the rear bumper are connected by a rod. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment to which the present invention is applied will be described with reference to FIGS.

As shown in FIG. 2, the rear frame 2 is provided with a rear bumper fulcrum bearing 11 and a platform fulcrum bearing 14. A rear bumper 13 is attached to the rear bumper fulcrum bearing 11, and a carrier 9 is attached to the carrier fulcrum bearing 14, respectively. The rear bumper fulcrum bearing 11 and the loading platform fulcrum bearing 14 have a rotatable hinge structure.
Reference numeral 13 denotes a structure in which a rear bumper fulcrum bearing 11 is used as a fulcrum, and the bed 9 is supported by a bed fulcrum bearing 14 as a fulcrum.

The rear bumper 13 is provided with a rear bumper-rod connection bearing 15, and the carrier 9 is provided with a carrier-rod connection bearing 1.
6 are provided respectively. The rod 17 is connected to the rear bumper 13 via a rear bumper / rod connection bearing 15 and to the carrier 9 via a carrier / rod connection bearing 16, respectively. The connection between the rear bumper / rod connection bearing 15 and the bed / rod connection bearing 16 has a rotatable hinge structure.

As shown in FIG. 2A, the rear bumper 13 is used in a substantially horizontal position during golf play. On the other hand, the loading bed 9 is fixed so that the golf club can be easily inserted and removed. In addition, the loading platform 9 and the rear cowl 22 are connected using a wire 18 for the purpose of reinforcing this portion. Note that when the riding golf cart is transported or stored,
As shown in (b), the loading platform 9 and the rear bumper 13 are rotated upward and flipped up to a substantially vertical direction. That is, the rear bumper 13 is connected to the rear frame 2 by a link mechanism using a rod 17 having a larger rotation angle than the loading platform 9.

However, when traveling on an uneven golf course with the golf bag 19 placed on the carrier 9, the carrier 9 rotates around the carrier bearing 14 as a fulcrum. Therefore, as shown in FIG. 1A, the hook 42 is used to move the rear frame 2 during use as the carrier 9.
And the rear bumper 13 are fixed to prevent the bed 9 from rotating around the bed fulcrum bearing 14 as a fulcrum. That is, the rear frame 2 is provided with a hook portion 42 having a hook portion fulcrum 44 having a rotatable hinge structure, and the hook portion 42 is configured to be engaged with the lock jig 41 of the rear bumper 13 (FIG. 1A). ). Therefore, in this state, the rear frame 2 and the rear bumper 13 are fixed, and the carrier 9 does not rotate around the carrier fulcrum bearing 14 as a fulcrum.

On the other hand, by pulling a lever (not shown) connected to the hook drive wire 43, the hook 42 connected to the hook 42 is released from the lock jig 41 of the rear bumper 13. In this state, by rotating the loading platform 9 and the rear bumper 13 upward and flipping them up to a substantially vertical direction, this portion can be folded (FIG. 1B). The hook 42
When the lever (not shown) is released, the hook is returned to its original state by the hook return spring 45.

[0016]

As described above, when the present invention is used, even when the golf bag runs on an uneven golf course with the golf bag placed on the carrier, the carrier is supported by the carrier supporting point bearing.
It does not rotate.
