[Problem that the idea aims to solve]

However, with this kind of cargo basket attachment device, the steering handle cannot be attached while the bicycle is running. When you turn the dollar bar left and right, the cargo basket will also swing in the same direction. Therefore, if a large amount of cargo or heavy cargo is stored in the cargo basket, the so-called hanger The situation where dollars are taken away is extremely dangerous. Make the maneuver easy and nimble It is difficult to accommodate heavy or large amounts of baggage, and the It's still an inconvenience for the carrier and other package delivery companies.

0004 Also, even when the bicycle is stopped, the front wheel or handlebars may be exposed to heavy loads or large amounts. Depending on the load, the vehicle may naturally swing to the left or right, causing the vehicle to easily roll over. That will happen. In particular, bicycles with one-legged standing stands are inherently unsafe. Coupled with the poor quality, the above-mentioned rollover accidents occur significantly.

[0005] Furthermore, the cargo basket is fixedly installed via multiple bolts and nuts as mentioned above. Therefore, the user can easily operate the cargo basket without using any tools. You can remove it and use it for shopping while carrying it with you, replace it with a new one, or renew it. It is not possible to exchange various cargo baskets of different sizes and shapes, and there is no intention to do so. It is also inconvenient in terms of taste.

[0006]

[Means to solve the problem]

This invention aims to improve these problems, and for this purpose, the structure of the vehicle body frame is A fixed cover is attached and integrated with the front pipe of the system, and a dotted distribution of holes is made of metal wire. The cargo basket is shaped in an intertwined state, and the frame is also made of metal wire in an almost L-shape when viewed from the side. The surface of the fixed cover and the rear surface of the rack are Insert the leg into one of the two, and insert the leg receiving tube into the other. , and the insertion leg can be freely inserted and removed from above into the receiving tube. This allows the rack to be supported in a fixed state on the fixed cover, and also to support the rack in a fixed state. The main feature is that the bottom of the cargo basket is removably locked and fixed to the horizontal surface of the container. It is.

[0007]

[Effect]

According to the above configuration of the present invention, the vehicle body frame forming the bearing member of the handle stem (15) A fixed cover (C) is integrally attached to the front pipe (14) of the frame (F). The cargo basket (B) has a support rack (R) that can be inserted and removed from its fixed cover (C). Since the handlebar (16) is locked and fixed through the bicycle, Even if you turn left or right while driving, or if you turn left or right while stopped, Even if it swings around, the cargo basket (B) does not swing together in the same direction, as shown in Figure 15. It remains fixed to the vehicle frame (F), and as a result, the cargo basket (B) is As a model, even if you store a large amount of luggage or heavy luggage, the so-called handle will not fit. There will be no dangerous phenomena such as bicycle overturning or bicycle overturning accidents.

[0008] Also, the cargo basket (B) is supported by the fixed cover (C) via its supporting rack (R). Because of this, it is made large enough to accommodate a large amount of luggage and heavy luggage. It can withstand this sufficiently, and the cargo basket (B) can be removed from its supporting rack (R). Since it is removable, you can carry it around and use it for shopping. , it is possible to exchange it for a new item, or for another item of various sizes and shapes. Ru.

[0009] Furthermore, the rack (R) for supporting the cargo basket (B) is also removed from the fixed cover (C). Since the cargo basket (B) is not in use, the Rack (R) It can also be prevented from leaving unsightly chisels on the vehicle body frame (F).

【Example】

The specific structure of the present invention will be described in detail below based on the illustrated embodiment. In FIG. 1, which schematically shows the entire structure, (F) shows the upper pipe (11) and the lower pipe (12). ) and the vertical pipe (13) are integrated into an overall almost triangular frame when viewed from the side. The intersection of the vertical pipe (13) and the lower pipe (12) is , are connected and fixed by a front pipe (14). However, for women's bicycles etc. As is known in the art, as a vehicle body frame (F) without an upper pipe (11), A front pipe (14) may be integrally erected at the upper end of the pipe (12).

[0011] (15) uses the front pipe (14) of the vehicle body frame (F) as a bearing member. A handle stem that is rotatably inserted into the inside of the handlebar from above, and from its upper end. Although the steering handlebar (16) is integrally extended and suspended horizontally, the steering handlebar (16) is At the lower end of the handle stem (15), there is a front fork for pivotally supporting the front wheel (17). (18) are connected and integrated. Therefore, move the handlebar (16) to the left or right. Needless to say, you can steer the bicycle by swinging it in the opposite direction.

0012 (C) surrounds the front pipe (14) of the vehicle body frame (F). A fixed cover applied from the front, which is made of a metal plate, as is clear from Figures 2 to 8. It is bent into a semicircular cross section that fits the surface of the front pipe (14), and , A pair of parallel mounting pieces (19) on the left and right extend towards the rear from the mid-height position. It is continuously extended and extended. However, if the mounting piece (19) is at a mid-height position, Instead of partially extending the fixed cover (C) backward, It may be bent into a long U-shaped cross section.

[0013] In addition, (20) is the mounting piece (19) facing each other in the fixed cover (C). Spacer blocks inserted between each other, with both sides of the fixed cover (C) By being fixed to the attachment piece (19) via a pair of left and right fastening bolts (21), The front pipe (14) is restrained from behind. (22) is its fastening bolt (21) A pair of holes are drilled on both the left and right sides of the spacer block (20) to accommodate the This is a screw hole.

[0014] In that case, the pair of left and right blank holes (23) that accept the fastening bolts (21) are 6, an elongated elongate extending parallel to the longitudinal centerline of said front pipe (14). These openings are arranged in a row on the mounting piece (19) of the fixed cover (C). This allows the spacer block (20) to connect to the upper pipe (11) and lower pipe (12). So that it can be placed reliably and smoothly between the top and bottom without interference. It has become.

[0015] In other words, the upper pipe (11) and lower pipe (12) that form the body frame (F) The distance between the top and bottom of the bicycle varies depending on the manufacturer of the bicycle and its model. Therefore, when attaching the fixed cover (C) to the front pipe (14), its installation The fastening bolt receiving hole (23) of the piece (19) is used as a slide adjustment elongated hole. In line with this, the installation height of the spacer block (20) was adjusted so that it could be moved up and down. It is positioned and fixed by the fastening bolt (21).

[0016] However, when applied to the vehicle body frame (F) without the upper pipe (11) as described above, In this case, spacer blocks (20 ) between the two mounting pieces (19) of the fixed cover (C). It may also be possible to install them by inserting them and fixing them with the fastening bolts (21). No. In addition, the fastening bolt (21) is as long as it does not interfere with the pressing bolt (described later). Instead of the two opposite left and right pairs as shown in the figure, the two mounting pieces (19) are It may be embodied as an assembly of one long fastening bolt and its fixing nut.

[0017] In any case, the spacer block (20) is at its installation height. After adjusting the positioning, the press bolt is operated to move forward and backward toward the front pipe (14) from the rear. (24) to be assembled and fixed to the front pipe (14) so as not to fall off. becomes. As a result, as is clear from Figures 2 to 4, the cover (C) fixed to the bolt is It is stably and firmly attached to the front pipe (14) of the arm (F). ( 25) is a press bolt receiving screw formed through the spacer block (20). The screw holes (26) are provided with fixing means such as welding or on both left and right sides of the fixed cover (C). Through continuous winding and bending, each pair of upper and lower legs can be received. It is a barrel that accepts the insertion legs of the luggage rack support rack described later from above. It has become.

[0018] On the other hand, (R) is a cargo basket support made of metal wire and shaped into an almost L-shape when viewed from the side. As is clear from Figures 9 to 12, from its upright back side there is a rack facing backwards. Therefore, the upper and lower mounting rods (27) are extended and extended, and the mounting rods (27) are extended. From the protruding tip of the attachment rod (27), the fixed cover (C) is connected downward. A pair of left and right insertion legs (28) that fit the leg receiving tube (26) are bent. I'm getting lost.

[0019] As is clear from Figures 2 to 4, the pair of left and right upper insertion legs (28) are attached to the fixing cover. Insert the lower insertion leg (28) downward into the upper receiving tube (26) of the bar (C). Insert and lock them into the receiving tube (26) so that they can be inserted and removed from above. , safely attach the rack (R) to the fixed cover (C) of the front pipe (14). This allows for precise installation.

[0020] However, as long as it can be installed in such a way that it can be inserted and removed freely, the male insertion leg (2 8) to the fixed cover (C) side, and the receiving tube (26) that acts as a female for the fixed cover (C) side. It is also possible to install them as accessories on the R) side. In addition, the above insert legs ( 28) is long and its receiving cylinder (26) is deep, the lower side difference shown in the figure is It is also possible to omit the plunger (28) and its receiving tube (26).

[0021] The horizontal surface of the rack (R) is equipped with a plurality of parallel metal wires, and A locking pin (29) is integrally planted upward, preferably from a corner of the horizontal surface. There is. (30) is applied to an arbitrary metal wire that forms the horizontal plane. It is a rotating ring that is inserted so that it can be moved freely, and has a locking hook (31) on its outer peripheral surface. The middle part is fixed and integrated by welding etc. This locking hook (31) The tip of the locking pin (29) is connected to the holes (3) scattered on the bottom of the cargo basket (B). 2), which is removably inserted and locked from below, and is supported at two points. This prevents the cargo basket (B) from rattling or swinging.

[0022] (33) is the above rotating ring (30) inserted in the horizontal plane of the rack (R). Separation between another metal wire parallel to the metal wire and the base end of the locking hook (31) It is a tension coil spring that is connected and hung between the left and right sides, and is normally connected as shown in Figure 12. As shown by the solid line, the tip of the locking hook (31) is aligned with the eye hole (32) of the cargo basket (B). It is elastically biased to have a locking effect.

[0023] In other words, paradoxically speaking, the locking hook (31) is suggested by the chain line in Figure 12. While resisting the elastic force of the coil spring (33), the rotating ring (30 ) is rotated around the fulcrum of the metal wire through which the tip of the metal wire is inserted. can be pulled out from the hole (32) of the cargo basket (B). be.

[0024] At that time, the locking pin (29) is in a fixed state with the rack (R), but the locking pin (29) is in a fixed state with the rack (R). The rack (31) has a metal plate that forms the horizontal surface of the rack (R) through its rotating ring (30). The coil spring (33) can also be slid along another metal wire. Therefore, it is possible to perform a following sliding action in parallel with the locking hook (31). Therefore, the tip of the locking hook (31) should always be inserted into the hole (32) of the cargo basket (B). This allows for accurate positioning and alignment, and in combination with the above-mentioned locking pin (29), the cargo (B) can be maintained in a stable and firm locked state.

[0025] As is well known, the cargo basket (B) itself is made of metal wire into a rectangular or elliptical shape in plan view. It is shaped like a circle, but as is clear from Figure 13, there is a locking pin on the bottom. Together with the lock (29) and locking hook (31), the cargo basket (B) can be fixed even more stably. A bending piece (34) is integrated with the backing. Bottom of cargo basket (B) and its attachment The horizontal plane of the rack (R) is formed by the upper and lower parts of the bent piece (34) to which it belongs. The metal wires to be made are sandwiched together as shown in Figure 14.

[0026] Regarding this point, in FIG. 13, one of the bent pieces (34) made of a metal plate is ), and the bent piece (34) can be easily inserted from the tip ( Although it is designed to be locked to the horizontal surface of R), the thick part that forms the bottom of the cargo basket (B) By partially bending the metal wire itself, one piece or multiple pieces in parallel The bent piece (34) is fixed to the horizontal surface of the rack (R) from below. It may be set as follows.

[0027] In any case, the locking pin (29) and locking hook (31) of the rack (R) are , can be pulled out from the hole (32) on the bottom of the cargo basket (B), and then removed from the cargo basket (B). Pull out the bent piece (34) attached to the bottom of (B) from the horizontal surface of the rack (R). Since it is also possible to remove the cargo basket (B), it can be used as a new product or in various sizes. It can be freely exchanged for a different item. In addition, the cargo basket (B) has a supporting rack ( Since it is separate and independent from R), a carrying handle (not shown) is attached to it in advance. If the bicycle is attached to a bicycle, it can be removed from the bicycle and used for shopping as is. Both are possible.
