Description

a stepping vehicle

technical field

The present invention relates generally to a straddle-type vehicle and in particular, but not exclusively, to a structure for a grab handle for said stride-type vehicle.

Background technique

Typically, grab handles made of aluminum or plastic are provided in two-wheeled vehicles, such as straddle vehicles, to facilitate a rear seat rider to hold the vehicle while riding. The grab handle also facilitates the rider when applying the vehicle's center stand. Contemporary two-wheeled vehicles also utilize the grab handle to enhance the overall aesthetics of the vehicle. For example, some two-wheeled vehicles use forked grab handles, which not only help provide grip support for passengers seated in the rear seats, but also help improve the overall aesthetics of the vehicle, When looking backwards.

A conventional bifurcated grab handle employed by two-wheeled vehicles includes a left grab handle and a right grab handle, each grab handle including mounting portions independent of each other. In other words, the left grab handle and the right grab handle are arranged such that they are separated and independently fixed to mounting brackets provided in the main body frame of the two-wheeled vehicle. However, due to variations that may occur in the body frame including the mounting brackets provided therein, securing the left and right grab handles independently of each other results in a difference in height/level between the two . Furthermore, the left and right grab handles, which are arranged independently of each other, also lack sufficient shape rigidity and tend to buckle due to loads.

In a known technique that attempts to solve the problem of form stiffness in the bifurcated grip handles, an additional member of generally triangular shape is provided for attaching each of the left grip handles to the right The mounting portions of the grab handles bridge each other from their top sides and thus contribute to increasing the shape rigidity of the left and right grab handles. However, the configuration of the left and right grab handles according to the above description results in a significant increase in the weight of the left and right grab handles, which is undesirable. In addition, manufacturing difficulty and manufacturing cost also increase.

Therefore, there is a need to overcome the problems described in the background art.

Contents of the invention

The present invention has been made in view of the above circumstances.

It is an object of the present invention to provide a straddle vehicle comprising a lightweight and strong grab handle.

Another object of the present invention is to provide a straddling vehicle comprising a handle having a structure that enhances the overall aesthetics of said straddling vehicle.

The above and other objects are achieved by providing a striding vehicle having a grab handle adapted to be mounted to be arranged at the rear of a body frame of the vehicle and under a seat of the vehicle rear mounting bracket. According to an aspect of the present invention, the grab handle integrally includes a left handle member and a right handle member, at least a part of each handle member protruding outward from under the seat and also extending along the side of the seat. The portion extends rearwardly toward the rear end of the vehicle. In particular, the left handle member and the right handle member extend independently of each other when viewed from the rear side of the vehicle.

According to an aspect of the present invention, the left handle member and the right handle member each include a mounting portion disposed in a front end, a support portion positioned behind the front end, and a grip portion disposed in a rear end. Additionally, the grab handle includes a bridging member bridging the support portions of the left and right handle members. In other words, the bridging member extends from the support portion on one side of the grab handle and terminates at the support portion on the other side of the grab handle. According to an aspect of the present invention, the bridging member is formed adjacent to the front mounting portions of the left and right handle members. The provision of the bridging member according to embodiments of the present invention helps to ensure that there is an equal load distribution between the left and right handle members which are behind separated at the ends. Furthermore, according to another aspect of the present invention, the support portion of each of the left handle member and the right handle member has a thickness substantially greater than that of the grip portion. Thus, the support portions on both sides of the grip handle together with the bridging members contribute to improving the form stiffness of the grip handle.

Furthermore, according to another aspect of the present invention, the width of the bridging member is not kept uniform throughout its length. For example, according to one embodiment of the invention, the width of said bridging member remains larger at its bridging portions compared to its central portion. The configuration of the bridging member according to an aspect of the present invention ensures that the weight of the bridging member and the weight of the grip handle do not increase significantly.

Thus, the construction of the grab handle according to the principles of the present invention ensures that the form rigidity of the grab handle is maintained without significantly increasing the weight of the grab handle. Moreover, since the left and right handle members are connected at the front, it is ensured that the grab handle is mounted to the rear mounting bracket as a single entity, thereby ensuring that in assembled state the left and right handle members are There is no height difference between the right handle members, thereby ensuring a comfortable grip for the rear seat rider.

FIG. 2 shows a perspective view of the main body frame 11 . It can be seen that the main body frame 11 includes a head pipe 11a, a main pipe 11b extending downward and rearward from the head pipe 11a, a pair of floor support pipes 11c supported to the main pipe 11b, A front span bridge 11d bridging the pair of floor support pipes 11c at the rear end of the support pipe 11c and a pair of side pipes 11e extending rearwardly and obliquely upward from the front span bridge 11d. At the rear ends of the pair of side pipes 11e is provided a rear mounting bracket 11f capable of receiving at least the grip handle 50 . A plurality of mounting bosses are provided in the rear mounting bracket 11f for receiving corresponding mounting settings of the grip handle 50 .

FIG. 3 shows a perspective view of the grip handle 50 . The grab handle 50 according to the present invention integrally includes a left handle member 50a and a right handle member 50b. In addition, each of the left handle member 50a and the right handle member 50b includes a mounting portion 51 arranged on the front end of the grip handle 50, a support portion 52 arranged on the middle portion of the grip handle 50, and A grip portion 53 on the rear end of the grip handle 50 . In particular, when the mounting portion 51 extends in the vehicle width direction, the support portion 52 extends upwardly and substantially obliquely from the support portion 51 toward the vehicle rearward direction. In addition, the grip portion 53 extends rearward from the support portion 52 toward the rear end of the vehicle and is bent. In this embodiment, the grip portion 53 of the left handle member 50a is kept separate from the grip portion 53 of the right handle member 50b. In other words, the left handle member 50a and the right handle member 50b extend independently of each other when viewed from the rear of the vehicle or from the side of the vehicle. Furthermore, the grab handle 50 integrally includes a bridge member 54 that bridges the support portion 52 of each of the left handle member 50a and the right handle member 50b. In this embodiment, and as shown in FIG. 3 , the bridging member 54 extends in the vehicle width direction, bridging the support portion 52 of the left handle member 50 a and the support portion 52 of the right handle member 50 b. Furthermore, as can be seen, the bridging member 54 is arranged behind the mounting portion 51 of the left and right handle members. The bridge member 54 according to the invention serves to increase the shape rigidity of the grip handle 50 . In addition, since the bridging member 54 is used to bridge the left handle member 50a and the right handle member 50b, in the assembled state of the handle member 50, no gap between the left handle member 50a and the right handle member 50b will occur. The level difference between the gripping portions of each of the right handle members 50b matters. Furthermore, since the bridging member 54 is disposed adjacent to the mounting portion 51, the bridging member 54 remains under a part of the seat 45 in the assembled state of the grip handle 50, thereby ensuring that only the left handle member and the gripping portion 53 of the right handle member can only be seen from the outside. Furthermore, the presence of the bridging member 54 also helps to close the through-space that may be formed between the seat 45 and the grab handle 50 when viewed from the rearward direction of the vehicle, thereby helping to enhance all Describe the aesthetics of the rear of the vehicle. Furthermore, in this embodiment, the width of the bridging member 54 is not uniform throughout its length. For example, in the present embodiment, the bridging portion 54 a of the bridging member 54 has a width greater than that of the central portion 54 b of the bridging member 54 . In other words, the width of the bridging member 54 remains larger at positions closer to the support portions 52 of the left and right handle members 50a, 50b, while remaining reduced at the central portion 54b. width. Since the reduced width is maintained at the central portion 54b, it is ensured that no unnecessary material addition to the bridging member 54 occurs, thereby ensuring an optimum weight of the bridging member 54 . Thus, the construction of the grip handle 50 according to the principles of the present invention helps to ensure sufficient form rigidity while maintaining its optimal weight.

Figure 4 shows an exploded view depicting the mounting of the grab handle 50 to the rear mounting bracket 11f according to an embodiment of the present invention. It can be seen that the mounting portion 51 of each of the left handle member 50a and the right handle member 50b is independently mounted to the rear mounting bracket 11f. In particular, one or more mounting holes 51a are provided in each mounting portion 51 of the left handle member 50a and the right handle member 50b, and the gripping handle 50 is fixed using fastener and washer members. In front of the rear mounting bracket 11f, the mounting holes 51a are aligned with corresponding one or more mounting bosses 11fa provided on both sides of the rear mounting bracket 11f. Therefore, although the mounting portion 51 of each of the left handle member 50a and the right handle member 50b is independently fixed to the rear mounting bracket 11f, the grip handle 50 is mounted to the rear mounting bracket 11f as a whole, This is due to the presence of the bridging member 54 bridging the left handle member 50a and the right handle member 50b. As a result, alignment problems between the left handle member 50a and the right handle member 50b relative to the rear mounting bracket 11f are eliminated.

FIG. 5 shows a cross-sectional view taken along line A-A depicting the position of the seat 45 and tool box 47 relative to the grip handle 50 . It can be seen that a part of the tool box 47 arranged under the seat 45 abuts against each lug member 51b provided in the mounting portion 51 of the left handle member 50a and the right handle member 50b . In particular, in this embodiment, the tool box 47 is sandwiched between a seat 45 arranged above it and a grab handle 50 arranged below it. A damper member 46 is provided in the base structure of the seat 45 , the damper member 46 protruding downwards towards the tool box 47 . According to this embodiment, when a load is exerted on the seat 45 by the rear seat occupant, load transfer occurs, from the seat 45 to said grab handle 50 . In particular, the damper member 46 compresses against a portion of the tool case 47 causing that portion of the tool case 47 to abut against the lug member 51b. Thus, the lug member acts as a load bearing member and prevents breakage of the portion that grips the handle, as well as any surrounding components.
