Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a rear carrier installed above a rear wheel of a two-wheeled vehicle such as a bicycle.
[0002]
[Background Art and Problems to be Solved by the Invention]
For example, in a bicycle, a carrier is conventionally provided above the rear wheel in order to load luggage and the like. FIG. 3 shows a conventional general bicycle 9, and FIG. 4 shows a conventional general rear carrier 1 provided thereon. As shown in these drawings, the conventional carrier 1 is provided with a placing portion 2 for placing a load, and a rear end of the bicycle frame 4 (that is, a rear wheel support portion). And a mounting portion 6 provided at the front end of the mounting portion 2 and connected to the tip of the saddle post support portion 5 of the bicycle frame 4. In this conventional example, the attachment portion 6 is attached to the tip of the saddle post support portion 5 together with the subframe 10 that connects the saddle post support portion 5 and the rear wheel support portion in a so-called co-tightened state. . That is, the carrier 1 is disposed above the rear wheel 7 while being supported and fixed by the leg portion 3 and the attachment portion 6.
[0003]
By the way, the conventional carrier 1 having such a structure has the following problems or requests for improvement.
(1) Since the carrier 1 is for carrying a load, it is desired to further increase the rigidity in order to improve practicality.
{Circle around (2)} In the conventional carrier 1, a pair of attachment portions 6 are provided, and these are arranged on both sides of the saddle post support portion 5. For this reason, the empty space below the saddle 8 becomes narrow, and particularly in the case of a vehicle equipped with a vehicle lock mechanism or the like below the saddle 8, there is a problem that the key operation is difficult.
[0004]
Under such circumstances, an object of the present invention is to provide a rear carrier for a motorcycle that can improve rigidity and can be compactly mounted on the motorcycle.
[0005]
[Means for Solving the Problems]
To achieve the above object, a rear carrier for a motorcycle according to the claims of the present application includes a main frame in which a rear wheel support part for supporting a rear wheel and a saddle post support part for supporting a saddle post are formed, and the saddle post support part. And a rear carrier for a two-wheeled vehicle that is used in a two-wheeled vehicle having a sub-frame that connects the rear-wheel supporting unit, and a mounting unit that is disposed above the rear wheel of the two-wheeled vehicle and can load a load, A leg portion that is connected to the rear wheel support portion and supports the placement portion, and a mounting portion that is provided on the placement portion and is connected to the subframe side to fix the placement portion. The mounting portion is fastened and fixed to a rear wheel lock circle lock provided in the subframe in a co-tightened state using a bolt for fixing the circle lock. .
[0006]
According to this configuration, by attaching the attachment portion to the subframe side, the length dimension of the attachment portion can be reduced compared to the case of attaching to the saddle post support portion as in the past. This reduces the bending moment applied to the entire carrier when an external force is applied to the carrier. In addition, the carrier can be installed in a compact manner, and a free space around the saddle can be secured. In addition, since the attachment portion can be so-called fastened together with the rear wheel lock circle lock provided in the subframe, the assembly work can be facilitated.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below.
FIG. 1 is a diagram showing a configuration of a motorcycle rear carrier (hereinafter referred to as “carrier”) 11 according to an embodiment of the present invention. In this embodiment, the carrier 11 is configured for a normal bicycle, but is not limited to a bicycle, and can be widely applied to two-wheeled vehicles in general. FIG. 2 is an enlarged view showing a state in which the carrier 11 is attached to a conventional general bicycle. The structure of a conventional general bicycle is the structure shown in FIG.
[0008]
Referring to FIG. 1, this carrier 11 can be formed by welding a round bar member made of metal, for example, and has a placement portion 12, a leg portion 13, and an attachment portion 14. Yes.
The placement portion 12 is disposed above the rear wheel 7 (see FIG. 3) of the bicycle 9 and places luggage. Therefore, as the mounting portion 12, for example, by bending the round bar member, an outer frame is formed so as to form a virtual plane along a plane perpendicular to the paper surface in FIG. A cross member or the like can be appropriately arranged on the inner side along the virtual plane. That is, a placement surface for placing the load is configured along the virtual plane. As shown in the figure, a hook 15 that protrudes downward can be provided on the lower side of the mounting surface of the mounting portion 12. The hook 15 can be used for hooking a rope or the like for fixing the load when the load is placed on the placement portion 12.
[0009]
Further, the leg portion 13 is formed so as to protrude below the mounting portion 12 and is connected to a rear wheel support portion of the bicycle frame 4 (see FIG. 3) via a predetermined connecting member 16. As a result, the placement portion 12 is disposed above the rear wheel 7. In addition, in this embodiment, although the leg part 13 and a connection member are made into a separate member, these can also be formed integrally.
[0010]
Furthermore, the attachment part 14 is substantially L-shaped as shown in the figure, is provided on the tip side of the mounting part 12 and is formed in a state of being bent obliquely downward. Although not shown in the figure, the attachment portion 12 is provided with an attachment hole for attachment. The mounting portion 14 is connected to the side of the subframe 10 of the bicycle 9 as will be described later. In this way, the mounting portion 12 is fixed by the mounting portion 14 and the leg portion 13. It has become.
[0011]
Next, the attachment portion 14 is fixed to a locking circle lock 17 of the rear wheel 7 provided in the subframe 10. The circle lock 17 is a general-purpose product that is widely used for bicycles, and is attached to the subframe 10, and the rear wheel 7 is locked by passing the member of the circle lock 17 through the rear wheel 7. Is. The circle lock 17 is fixed via an attachment bracket 18 fixed to the subframe 10. In this embodiment, this fastening method employs a fastening structure using bolts. The mounting portion 14 is fastened in a so-called co-tightened state using a bolt 19 for fixing the circle lock 17.
[0012]
According to the carrier 11 according to the present embodiment, by attaching the attachment portion 14 to the subframe 10 side, the length dimension L of the attachment portion 14 (see FIG. Reference) can be kept short. Thereby, when an external force is loaded on the carrier 11, the bending moment applied to the entire carrier 11 is reduced. As a result, the carrier 11 can have sufficient rigidity with little deflection.
[0013]
In addition, since the carrier 11 can be installed in a compact manner, an empty space around the saddle 8 can be widened. As a result, even if a required mechanism such as the parking lock mechanism 20 is provided around the saddle 8, the mechanism can be smoothly operated. In addition, since the attachment portion 14 can be so-called fastened together with the circle lock 17 provided on the subframe 10, there is also an advantage that the assembling work can be facilitated.
[0014]
【The invention's effect】
As described above, according to the present invention, the bending moment acting on the carrier can be reduced by suppressing the length of the mounting portion, and the carrier can have sufficient rigidity with little deflection. In addition, since the two-wheeled vehicle can be compactly installed to provide a wide space around the saddle, even if a required mechanism is provided around the saddle, the mechanism can be smoothly operated.
