Description

[Detailed description of the invention] (a) Field of industrial application The present invention relates to a bicycle carrier and its accessory equipment that can be easily converted into three forms: flat, basket-like, and child-carrying. It is particularly safe.

(b) Conventional technology Conventional bicycle rear wheel carriers are mainly flat, and depending on the user's requests, basket-shaped storage devices or child carriers can be placed on the flat carrier using metal fittings. Installation is underway. There are several types of child carriers, and some that can be converted into a cage are also available.
However, all of these require tools such as spanners to attach and remove, and cannot be easily done by the user. In addition, if these basket-shaped storage devices or child carriers become unnecessary and attempt to return to a flat state while the bicycle is running, it is difficult to load the removed basket-shaped storage devices or child carriers with the cargo. .

With conventional child carriers, when the bicycle is tilted significantly, there is a great risk that the child may fall out of the carrier.

In addition, ropes for securing cargo are tied around the cargo bed when not in use, so they are easily damaged by exposure to sunlight, wind and rain, and can be easily removed, so there is a high risk of theft. There were some shortcomings.

(c) Problems to be solved by this invention This invention was devised to solve the following problems.

(1) To provide a shape that can be easily and quickly converted into three forms: flat, basket-like, and child-carrying form without requiring any tools such as a spanner.

(2) After the above three form conversions, there is no need to treat the components as cargo.

(3) To prevent the child from falling if the bicycle tilts significantly when carrying a child.

(4) The rope used for the loading platform must be able to withstand long-term use and must not be easily stolen.

(5) To provide a method for using the above rope effectively and easily.

(d) Means for solving the problem (1) Loading platform that forms the main part of the structure If the structure of the present invention is explained with reference to the drawings,
As shown in Figures 2 and 3, a symmetrical hexagonal bottom surface, a front surface fixed at right angles to the bottom surface around the bottom surface, and a side surface that can be folded freely with the bottom surface.
,, Similarly, the main feature is to provide a foldable rear surface.

(2) Loading area that forms the bottom The bottom has a symmetrical hexagonal shape as shown in Figures 1, 2, and 3, and is constructed to sufficiently withstand the load of the loaded items. At the corners of the bottom surface, six hooks for hanging ropes for holding the loaded object are attached slightly overhanging the bottom edge and facing downward. As shown in (3), (4), (5), and (6) in this section, the area around the bottom is
Place the sides, , and rear.

(3) Loading area forming the front surface As shown in Figures 1, 2, and 3, the front surface extends over one side in front of the bottom surface and a portion of both adjacent sides, and is fixed to the bottom surface while maintaining a right angle. When the front side is shaped like a basket with the top side slightly longer than the bottom side, it is desirable that the adjacent side faces open upward. The upper part of the front line is higher than the upper part of both side lines, and a handle is attached to the inside of the upper end for grasping when loading a child.

It is desirable that both ends of the handle are bent slightly backwards to make it easier to grip, and that rubber coatings be attached. As shown in Figure 8, the rope storage reel and its accessories described in (8) Rope-related equipment in this section are attached to the front outer surface.

(4) The loading platform forming the sides The sides are attached to the bottom to the left, right, or near the front so that they can be folded up as shown in Figures 1, 2, and 3. The sides are approximately the same length on the top, bottom, left and right, and one corner of the bottom is cut out so that when folded down, it does not hit the hook attached to the bottom. When the sides are folded down to the outside of the bottom, there is a
A footrest plate and a footrest are attached to the sides so that they can be folded freely. The protruding length of the footrests and legs is slightly longer than the child's footwear, and a chain is attached to the tip to connect it to the sides. The chain shall be of sufficient length and have sufficient tensile strength so that when fully extended, the footrest plate and the side face are perpendicular to each other. Also, when not in use, the footrest board
Provide a latch so that it fits tightly. side,
is attached to the bottom on the left and right sides of the bottom so that it can be folded freely. The sides should be at the same height as the sides, and the opposite side should be slightly longer than the side in contact with the bottom, so that when it is shaped like a basket, it opens upward. Also, the bottom two corners are cut out so that they do not hit the hooks attached to the bottom.

(5) Loading area forming the rear surface The rear surface is attached to the rear end of the bottom surface so that it can be folded freely with the bottom surface as shown in FIGS. 1, 2, and 3. It is desirable that the rear surface be at the same height as each side surface, and that the opposite side be slightly longer than the side in contact with the bottom surface, so that when it is shaped like a basket, it opens upward. Also, the bottom two corners are cut out so that they do not hit the hooks attached to the bottom.

(6) Connections between each surface Bottom and side, rear connection and side, and footrest attached to it〓,〓
All of the connecting parts are foldable, and the necessary number of hinges or rings with the same function are attached to these parts. Front, side...
, small rings as shown in FIG. 5 are provided near the left and right upper ends of each of the rear surfaces so that they can be arbitrarily connected or disconnected between adjacent surfaces. A total of six connection fittings, an example of which is shown in the figure, are prepared.

(7) Materials of the structure The bottom, front, sides, back, and footrest plates are all reinforced with wire rods made of the same material around the mesh-like parts such as diamond, square, and round holes. Make it into a molded product. The bottom and front surfaces need to be reinforced as appropriate, as well as the periphery. The materials of each of the above-mentioned surfaces, the handle, the folding part, the small ring, the connecting fittings, and the rope storage reel and its accessories, which will be described later, are all metal or hard plastic. However, the covering at both ends of the handle shall be made of rubber, or the rope shall be made of rubber-filled cloth. These constituent materials are materials that can best realize the characteristics and effects of the present invention, but it goes without saying that they may be manufactured using conventional materials used in such cargo platforms.

(8) Rope-related equipment The ropes used to secure the loaded items and maintain safety shall be wound and stored on a reel. 1st
As shown in Figures 1, 2, 3, and 8, the rope storage reel is placed on the outside center of the front and slightly below the center, and a lever is placed on top of it to restrict its rotation.
Also, a covering is provided to cover these. The rope has a diameter of about 7 mm and a length of about 2 mm, and its end is screwed to the core of the reel. The reel shall have a diameter of approximately 120 mm and have sufficient capacity to store the rope. A continuous notch is provided on the edge of one side of the reel over the entire circumference. The lever has a spring for pressing its tip against the notch and a push portion for releasing the tip from the notch. In order to pass the rope when carrying a child, four twist loops as shown in Figure 6 are attached to the part where the rope is pulled out from the reel, and at appropriate locations on the sides, rear, and sides, and the tip of the rope is hooked. For this reason, a retaining ring as shown in FIG. 7 is provided near the front side.

(9) Attaching the cargo bed Instead of the conventional flat cargo bed above the rear wheel of a bicycle, the cargo bed of the present invention has a support that stands up almost vertically from the end of the rear wheel shaft, and a support that protrudes almost horizontally from below the saddle and is supported by this support. It is preferable to attach it directly to the frame material. However, even if a conventional loading platform is already installed, if the width is not wide enough, the loading platform of the present invention can be installed on top of it by using metal fittings. In order to ensure safety at night, it is desirable to attach a reflective red warning sign to the rear.

(e) Effects and examples of the present invention First embodiment: When used as a flat surface.

If the load is larger than the bottom plate A, use it as a flat surface.

As shown in Figure 1, the six metal fittings (an example of which is shown in Figure 4) connecting the side, , and rear surfaces are connected to six pairs of small rings (shown in Figure 5).
After removing these surfaces and lowering them to the outside of the bottom plate, reconnect them by passing the four metal fittings through the four pairs of small rings to prevent these surfaces from rattling. In addition, the footrests and footrests are attached to the sides using respective hooks.

After loading the load, press the lever to fully pull out the rope from the reel. After hooking the hook at the end of the rope to any one of the six hooks facing downward at the corners of the bottom, tighten the load so that it does not move and hook it to the hook on the opposite side to tie it up. To go. After hanging the last hook, the excess rope can be taken up by turning the reel clockwise while keeping the lever spring active.
To loosen the rope when unloading a load, simply press the lever and the reel will rotate counterclockwise to reach its destination. When the rope is not in use, hang the hook at the tip of the rope on the twist ring of the rope drawer, turn the reel clockwise, and wind it up.

Second embodiment: When used as a basket.

If the load is smaller than the bottom plate or in the form of a pile, use it as a basket. As shown in Figure 2, remove the four metal fittings connecting the sides (an example is shown in Figure 4) from the four pairs of small rings (shown in Figure 5). A basket shape is formed by lifting and connecting all six metal fittings and all six pairs of small rings. In this case, the footrests 〓 and 〓 hang down inside the sides without any operation, so there is no problem in accommodating the cargo inside the cage. If there is a risk that the loaded object may escape from the cage, the rope can be pulled out from the reel and used as in the first embodiment.

Third embodiment: A case where a child is loaded.

After use in the cage prior to loading the child,
Remove the four connecting fittings (an example of which is shown in FIG. 4) associated with the side surfaces from the four pairs of small rings (shown in FIG. 5), and fold the side surfaces down to the outside of the bottom surface. At this time, if the footrests 〓 and 〓 are removed from their latches, they will be suspended by chains and held almost horizontally. Place the child's feet on the child's rear foot rest plate and have them grasp the handle. Next, press the lever and pull the rope. The reel will rotate counterclockwise and the rope will be pulled out. Twist the rope and pass it through the four rings (shown in Figure 6) one after another, and then tighten the hook at the end of the rope. hook on the retaining ring (shown in Figure 7). Then, while pulling the rope toward the source and tensioning it, rotate the reel clockwise to take up the excess rope. At this time, the rope is placed above the child's thighs, preventing the child from falling even if the bicycle is tilted significantly. When removing a child, press the lever to loosen the rope, remove the hook at the end of the rope from the retaining ring (shown in Figure 7), and remove the rope one after another from the three twist rings (shown in Figure 6).
After hooking the end of the rope to the twist ring of the rope drawer, turn the reel clockwise to create appropriate tension.

(F) Effects of the present invention (1) By using the bicycle carrier of the present invention, it can be carried in three forms depending on the object to be loaded: flat, basket-shaped, and child-carrying without the need for any tools or techniques. , it is possible to convert extremely easily and in a short time, and is extremely convenient.

(2) The bicycle carrier of the present invention has a reel and its attached equipment so that ropes can be easily used to secure the loaded object, making it possible to transport it extremely easily and safely. It has many effects. Also, damage and theft of the rope can be prevented.
