Description

[Detailed description of the invention]

[0001]

[Usage field to which the invention belongs]

 The present invention relates to a bicycle cart mounted on a rear carrier or near a handle of a bicycle.

[0002]

[Prior art]

 As the bicycle luggage, a rear luggage attached to the rear luggage carrier and a front luggage attached to the front side of the handle portion are well known. These are generally made of resin or metal (wire). The upper part was formed in an open box shape.

[0003]

[Problems to be solved by the invention]

 Since the shape of the above-mentioned cargo baskets is standardized, it may not be able to be loaded when there are many or large luggage. Therefore, it has been desired to increase the loading capacity. However, simply increasing the size of the cargo basket in order to increase the load capacity would cause the cargo basket to always protrude forward and backward from the bicycle, and this would result in a biased center of gravity and poor balance. However, there has been a problem that driving becomes difficult.

[0004] Furthermore, in the case of a large cargo basket, there is also a disadvantage that when a small cargo is loaded, the possibility that the cargo moves largely in the basket or jumps out increases. On the other hand, in the rear cargo basket of this kind, which is mounted on the rear carrier, the upper ends of the front, rear, left and right walls are generally formed at a certain level which is horizontal to each other. It is. Therefore, when driving or getting on / off the bicycle, the buttocks and clothes of the driver may touch the upper end of the front wall of the rear cargo basket and hinder the movement, or the clothes may be damaged at this time.

In order to avoid such a situation, when the rear cargo basket is mounted to the rear of the rear cargo bed, the rear cargo basket projects greatly to the rear of the bicycle, and the center of gravity is lowered similarly to the above. There was a problem that the driving balance of the bicycle became poor and it became difficult to drive. The present invention has been made in view of the above circumstances, and when the amount of luggage is small or not, the loading capacity is reduced, the overhang from the bicycle is suppressed, and the driving is not adversely affected. The purpose of the present invention is to provide a bicycle cart that can be loaded when the amount of luggage is large.

[0006] In addition, when the cart is mounted on the rear carrier of the bicycle, it does not interfere with driving or getting on and off the bicycle, and the center of gravity of the bicycle is prevented from lowering to the rear. The purpose is to provide a bicycle cart that minimizes outgoing traffic.

[0007]

[Means for Solving the Problems]

 In the present invention, the following technical measures were taken to achieve the above object. That is, the bicycle luggage basket according to the present invention has a pair of cage halves opened upward and on one side, and the pair of cage halves face each other on one side. It is characterized in that it is capable of forming a cage as a state and is slidably connected in the facing direction so as to increase or decrease the load capacity.

[0008] As described above, the cargo basket has a pair of cage halves, and the pair of cage halves is slidably connected to each other. By sliding the car halves closer to each other in the facing direction, it is possible to suppress the overhang from the bicycle while reducing the load capacity, worsening the driving balance and reducing the load inside the car. It is possible to prevent luggage from moving or jumping out. When the load is large or large, the load capacity can be increased by sliding the pair of cage halves away from each other in the direction facing each other, so that the load can be loaded.

The pair of cage halves can be slidably connected with a simple configuration by connecting them in a fitting relationship in which one of them is internally fitted and the other is externally fitted. become able to. The pair of cage halves, the front cage half opened at the rear part, and the basket half after the front part is released, the front cage half is provided with a mounting portion to the rear cargo bed of the bicycle, If the rear cage half is configured to be slidable in the front-rear direction with respect to the front cage half, it can be used as a rear cargo basket.

In this case, when the amount of luggage is small, the entire length of the rear cargo basket can be shortened by sliding the rear cage half forward, so that the rearward projection is reduced. The center of gravity can be positioned forward, making it easier to drive the bicycle. Also, when there is a lot of luggage, the rear basket half can be slid backward to greatly increase the load capacity. In the case of the rear cargo basket as described above, a notch portion corresponding to the saddle of the bicycle is formed at the upper part of the front wall of the front cage half, so that the rear cargo basket can be used when driving or getting on and off the bicycle. Is prevented from obstructing the upper part of the front wall. In addition, since the rear luggage can be mounted as forward as possible with respect to the rear luggage carrier of the bicycle, the center of gravity of the bicycle as a whole can be positioned as forward as possible.

[0011] The pair of basket halves are constituted by the front basket half and the rear basket half as described above, and the rear basket half is provided with a mounting portion near the handle of the bicycle. By configuring the front cage half so that it can slide in the front-rear direction, it can be used as a front load basket. Even in this case, when the luggage is small, the entire length of the front cargo basket can be reduced by sliding the front cage half backward, and the bicycle can be prevented from protruding forward. Also, by sliding the front basket half forward, the loading capacity can be greatly expanded.

In the front basket half and the rear basket half, the front and rear guide grooves fit between the contact portions between the left and right side walls and between the contact portions between the bottom plate portions. By providing slide guide means in combination with a guide shaft, or by providing reinforcing ribs that also serve as slide rails that engage up and down between the upper ends of the left and right side walls, sliding of the rear basket half can be achieved. It can be held and performed stably. The pair of cage halves are rotatably connected about a horizontal axis at a lower portion thereof, and one of the cage halves is mounted on a bicycle, and the other cage half is rotated downward. The capacity can be increased or decreased by forming a seat with the bottom plate of one car half as the seating surface and the side wall facing the open side of the other car half as a footrest. It can be used not only as a cargo basket, but also as an auxiliary seat for children, for example.

[0013]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 5 show a first embodiment of a bicycle luggage basket 1 according to the present invention. The luggage basket 1 of this embodiment is mounted on a rear luggage carrier 16 of a bicycle 12 as shown in FIG. It is considered a rear cargo basket. As shown in FIGS. 1, 2 and 4, the rear cargo basket 1 is surrounded by a front wall 2, a rear wall 3, and left and right side walls 4, 5 so as to surround the bottom plate 6 in all directions. In the present embodiment, the box type is formed by a front cage half 10 having upper and rear sides released and a rear cage half 11 having upper and front sides released. It has been formed.

That is, with the release side of the rear side of the front cage half 10 and the release side of the front side of the rear cage half 11 facing each other, the rear cage half 11 is fitted inside, The front cage half 10 is connected in a fitting relationship in which it is fitted externally. The front basket half 10 and the rear basket half 11 are formed of a suitable resin material such as PP, nylon, ABS, or polycarbonate, and the front wall 2, the rear wall 3, and the left and right side walls 4, 5 It is formed as a net structure, a lattice structure, a porous structure, a braided structure, or a boarded structure without holes.

In the rear cargo basket 1, the front wall 2 is formed lower than the other peripheral walls. Therefore, the left and right side walls 4 and 5 are provided with a slope which descends forward near their front portions. It is. A cutout portion 14 corresponding to the saddle 13 of the bicycle 12 is formed in the front wall 2 at the upper portion in the center in the left-right direction as shown in FIG. Since the notch 14 is provided, when the rear cargo basket 1 is mounted on the rear cargo platform 16 of the bicycle 12, not only the saddle 13 but also the buttocks of the driver (not shown) sitting on the saddle 13 are provided. This prevents the user from touching the upper end of the front wall 2 with clothing or clothes. In addition, when it is mounted on the rear carrier 16, it can be positioned as close to the front as possible.

The front basket half 10 is provided with a mounting portion 18 for mounting the bicycle 12 on the rear carrier 16. The mounting portion 18 is provided with long recesses 19 in the left and right direction at two front and rear portions of the bottom plate portion 6a of the front cage half 10, and a plurality of through holes 20 are provided in each of the recesses 19. It consists of being. Therefore, as shown in FIG. 2, a fastener 21 such as a screw or a rivet is inserted into these through holes 20, and is directly or indirectly connected to the rear carrier 16 through the mounting bracket 22, thereby obtaining the rear part. The front cage half 10 can be mounted on the carrier 16.

In the fitting portion between the front basket half 10 and the rear basket half 11, the left side walls 4a and 4b and the right side walls 5a and 5b are in contact with each other, and the bottom plate parts 6a and 6b are in contact with each other. Abuts. Then, two points are set between the contact portions between the left side walls 4a and 4b and between the contact portions between the right side walls 5a and 5b and the contact portions between the bottom plate portions 6a and 6b. The slide guide means 25 is provided in a total of four places including the place. Each of these slide guide means 25 is provided in one of the front cage half 10 and the rear cage half 11 in the front-rear direction, and is provided in the other half thereof and fits in the guide groove 26. The combination with the guide shaft 27 is provided.

For this reason, the rear basket half 11 is slidable in the front-rear direction with respect to the front basket half 10. As shown in FIG. 4, an auxiliary slide guide means 30 is provided between the contact portions of the bottom plates 6a and 6b so as to be sandwiched by the two slide guide means 25 described above. . The auxiliary slide guide means 30 combines an auxiliary guide groove 31 provided in the rear basket half 11 in the front-rear direction with an auxiliary guide shaft 32 provided in the front cage half 10 and fitted in the auxiliary guide groove 31. It is a thing.

The auxiliary guide groove 31 is provided with circular stopper engagement holes 33 at both ends. On the other hand, the portion of the auxiliary guide shaft 32 that fits in the auxiliary guide groove 31 is a plate-shaped projection corresponding to the groove width, and the horizontal rotation around the axis is possible in the stopper engagement hole 33. ing. That is, when the auxiliary guide shaft 32 (plate-like projection) is oriented in the front-rear direction, the rear basket half 11 can be slid, but the auxiliary guide shaft 32 reaches the stopper engagement hole 33. Then, when the auxiliary guide shaft 32 is rotated (the state shown in FIG. 4), the auxiliary guide shaft 32 (plate-shaped projection) comes out of the stopper engagement hole 33 into the auxiliary guide groove 31. Therefore, the rear cage half 11 cannot be slid.

As a result, it is possible to fix the position of the rear basket half 11 in a state where it is slid to the frontmost position and the rearmost position. In at least one of the slide guide means 25, the guide shaft 27 is set to be rotatable by about 90 ° or 180 °, and by this turning operation, the opening edge of the guide groove 26 is pressed. If the structure is such that a cam action (stopper function) that can be loosened can be generated, the position of the rear cage half 11 can be fixed even during sliding, which is more preferable.

On the other hand, as shown in FIG. 5, the left and right side walls 4a and 5a of the front cage half 10 are crank-folded at their upper ends outward in the left-right direction. The reinforcement rib 35 is formed. The reinforcing rib 35 forms an upwardly facing step surface 36 on the inner side of the box. On the other hand, the upper ends of the left and right side walls 4b, 5b of the rear basket half 11 are crank-folded outward in the left-right direction in the same manner as the reinforcing ribs 35 at positions corresponding to the reinforcing ribs 35. Therefore, a reinforcing rib 37 is formed at the crank folded portion. The reinforcing rib 37 forms a step surface 38 facing downward on the outside of the box.

The stepped surface 36 formed by the reinforcing ribs 35 of the front cage half 10 and the stepped surface 38 formed by the reinforcing ribs 37 of the rear cage half 11 are engaged with each other in the vertical direction. The slide rail portion 40 is formed by this engagement. That is, by forming the slide rail portion 40 at the portions (reinforcement ribs 35, 37) where the mechanical strength is increased to prevent bending and warping, the slide of the rear cage half 11 is more stably guided. I can do it. FIGS. 6 and 7 show a second embodiment of the present invention, in which the cargo basket 1 of this embodiment is a front cargo basket mounted near the handle 42 of the bicycle 12.

The front cargo basket 1 has a front cage half 10 and a rear cage half 11 similarly to the first embodiment, but is provided with a front side and a rear side.

A rotation guide groove 61c extending in an arc from the lower end of the stopper groove 61b to the auxiliary side wall 58. Therefore, when the front cage half 10 is slid forward, as shown in FIG. 9, the forward movement is restricted by contacting the rear ends of the slide grooves 60a and 61a with the guide shaft 27, and the load capacity is increased. State. Then, the front cage half 10 is slightly lifted until the guide shaft 27 abuts on the lower ends of the stopper grooves 60b, 61b, and the front cage half 10 is turned forward and downward using the lower guide shaft 27 as a lateral support shaft. By moving, the upper guide shaft 27 moves in the rotary arc groove 61c, and when the guide shaft 27 comes into contact with the rear end position of the arc groove 61c, the rotation is regulated. (See FIG. 10).

In this state, the bottom plate 6b of the rear basket half 11 is used as a seat surface, and the front wall 2 of the front basket half 10 is used as a footrest to be used as a child seat. The cargo basket 1 in the present embodiment may be attached to the rear carrier 16 of the bicycle 12, or the pair of cage halves 10, 11 may be attached to the left and right directions. FIG. 11 shows a fourth embodiment of the present invention, in which a pair of cage halves 10 and 11 are not connected in a direct fitting relationship by internal fitting and external fitting. , Are indirectly connected with a connecting cage body 62 interposed therebetween.

That is, the connecting cage body 62 is formed in a U-shape having a bottom plate 63 and a pair of side walls 64 extending upward from the opposing side of the bottom plate 63, and the connecting cage body 62 has a release side. The open sides of the cage halves 10 and 11 face each other and are connected in a fitting relationship by internal fitting, and a pair of cage halves 10 and 11 are connected to each other via the connecting cage 62.
