Description

Locomotive steering mechanism

The present invention relates to a locomotive steering mechanism, and more particularly to a locomotive steering mechanism that can provide the function of a mounted item.

In general, due to structural constraints, current straddle locomotives are not capable of providing a storage helmet. Even if the helmet is barely mounted on the side of the straddle locomotive, the helmet is easily damaged by collision.

The present invention basically employs the features detailed below in order to solve the above problems. That is, the present invention includes a frame head tube having a hook, wherein the hook has an opening; a steering shaft is rotatably disposed in the head tube of the frame; and an upper tripod Attached to the steering shaft, and having an extension protrusion, wherein the extension protrusion abuts the hook of the frame head tube in a detachable manner for selectively closing the opening of the hook.

Meanwhile, the locomotive steering mechanism according to the present invention further includes a lower tripod, wherein the lower tripod is coupled to the steering shaft, and is disposed relative to the upper tripod, and the frame head pipe system is disposed thereon Between the tripod and the lower tripod.

In the present invention, the locomotive steering mechanism further includes a steering handle coupled to the upper tripod.

The above described objects, features and advantages of the present invention will become more apparent from the description of the appended claims.

The preferred embodiment of the invention is described in conjunction with the drawings.

Referring to FIG. 1 , FIG. 2 , FIG. 3 , and FIG. 4 , the locomotive steering mechanism 100 of the present embodiment is suitable for use in a straddle locomotive M, and mainly includes a frame head tube 110 and a The steering shaft 120, an upper tripod 130, a lower tripod 140 and a steering handle 150.

The frame head tube 110 has a hook 111 that can be used to mount an item (e.g., a helmet). Further, as shown in FIGS. 2, 3, and 4, the hook 111 has an opening 111a.

The steering shaft 120 is disposed in the frame head tube 110 in a rotating manner.

The upper tripod 130 is fixedly coupled to the steering shaft 120, and the upper tripod 130 has an extended protrusion 131. Here, the extension protrusion 131 is a hook 111 that is detachably abutted against the frame head tube 110, and can be used to selectively close the opening 111a of the hook 111.

The lower tripod 140 is also lockedly coupled to the steering shaft 120, and the lower tripod 140 is opposite the upper tripod 130. Here, the frame head tube 110 is disposed between the upper tripod 130 and the lower tripod 140.

As shown in FIGS. 1 and 5, the steering handle 150 is lockedly coupled to the upper tripod 130.

Next, the operation of the locomotive steering mechanism 100 will be described.

First, as shown in FIGS. 1 and 2, when the straddle locomotive M is in the normal running state or its steering handle 150 is not turned to the left side of the straddle locomotive M, the frame head tube 110 is The hook 111 is an extended protrusion 131 that is separated from the upper tripod 130.

On the other hand, as shown in FIGS. 3, 4, and 5, when the hook 111 of the frame head tube 110 mounts a cap (not shown) or other item of the helmet H, the steering handle 150 can be turned to the bottom of the straddle locomotive M to the bottom lock. Here, the steering shaft 120 is rotated by the steering handle 150, thereby driving the upper tripod 130 to rotate. At this time, the extending protrusion 131 of the upper tripod 130 overlaps the hook 111 of the frame head tube 110, thereby closing the opening 111a of the hook 111. As described above, the helmet H or other items attached to the hooks 111 can be firmly held on the hooks 111 without being dropped or removed from the hooks 111.

In summary, the locomotive steering mechanism 100 disclosed in the present invention can provide a stable steering function and prevent the article from being stolen in the existing space, thereby improving the use of the locomotive steering mechanism 100. Convenience.

Although the present invention has been disclosed in its preferred embodiments, it is not intended to limit the present invention, and it is possible to make some modifications and refinements without departing from the spirit and scope of the present invention. The scope of the invention is defined by the scope of the appended claims.
