The present invention relates to a structure for a bicycle infant loader that can be used as a loader.

[Prior Art] Design No. 643183 as a conventional infant loader for bicycles of this type.
The technique described in the publication can be mentioned.

In the bicycle infant loading described in the publication, another wire is arranged in parallel and fixed on the front, back, left and right, and the bottom of the frame formed in the shape of a square pole by wire as a support for supporting the contents. It is integrally formed in a rectangular box shape, and it is possible to put a baggage as an item to be stored therein or put an infant on it.

In addition, as for patent publications, Japanese Examined Patent Publication No. 53-14821 and Japanese Utility Model Publication 61
-There is a technology published in the publication No.

In the Japanese Patent Publication No. 53-14821, a member composed of a bottom wall plate forming a car body and a one-sided wall plate forming the peripheral side wall of the car body, and a member symmetric to the one-sided wall plate forming the peripheral side wall of the car body Manufacture to form a bicycle car body by separately forming a face wire plate and a member integrally formed with adjacent other face wall plates on both sides with a metal wire rod, coating the same with a synthetic resin, and then integrating both members and connecting them. A method technique is disclosed.

Further, in Japanese Utility Model Laid-Open No. 61-76784, the bottom of a box whose upper part and first side are opened is extended to form an overhang, and the end of the overhang is raised. A holding body is provided with a gripping portion at the upper end of the holding body, which can be held by an infant, and a pivotal support portion is provided on the second side portion and the third side portion of the box body which face each other.

On the other hand, Japanese Utility Model Publication No. 58-33017, Japanese Utility Model Publication No. 52-154857 and Japanese Utility Model Publication No. 57-153089 disclose a technique of using a mesh member for carrying a bicycle infant.

[Problems to be Solved by the Invention] The conventional infant loader for bicycles is disclosed in the above design No. 643183,
As described in JP-B-53-14821 and JP-B-61-76784, a plane is formed by arranging wire rods in parallel, which forms a child support for bicycles. A gap extending in the direction was formed. The width of the gap between the wire rods is relatively large, but there was no particular problem when an infant or a large object was placed on the basket. However, if small or slender luggage is placed, the luggage may fall through the gap between the wire rods.

Further, in the technique disclosed in Japanese Utility Model Publication No. 58-33017, when the infant is placed, the opening / closing frame serves as a foot rest for the infant. Therefore, when the infant is placed on the cargo basket, a net is provided on the side and rear side of the infant. If it is stretched, the mechanical strength is lowered and the safety against sway of the bicycle becomes a problem. In addition, the foot of the infant can move back and forth, and the foot may be caught in the wheel.

Further, as disclosed in Japanese Utility Model Laid-Open No. 61-76784, when a bicycle infant is formed by a box made of a flat plate, the air resistance increases and the stability of the bicycle decreases when a cross wind is received. Become. In addition, when a bicycle child carrier is formed by a box, the design of the bicycle itself is a shaped body centered on the line, and if a flat plate is attached thereto, the harmony of the overall design is lost and it is not preferable in terms of design. And, the actual Kaisho 61
As described in JP-A-76784, even if a bicycle infant board is formed with a box made of a flat plate, there is a gap with the moving part, giving the user a sense of security that there is no gap between the wire rods. In addition, there is a possibility that a small baggage or a slender baggage may be dropped.

Further, as described in Japanese Utility Model Laid-Open No. 61-76784, the material cost is high even if wood or synthetic resin is used to form a bicycle infant support with a box made of a flat plate. In addition, it is difficult to reduce the waste of material and to use it efficiently, and in particular, for injection molding the whole with synthetic resin, the mold and injection molding machine become large and the production cost becomes expensive. In addition, structurally, it cannot always be processed into the simple shape shown.

Here, it will be examined whether or not the techniques disclosed in Japanese Utility Model Laid-Open No. 52-154857 and Japanese Utility Model Laid-Open No. 57-153089 can be used for each of the known techniques.

The technique disclosed in Japanese Utility Model Publication No. 52-154857 is for forming a side plate structure by squeezing a mesh plate, and forming a car by forming a pair of side plate structures. It is difficult to apply it even when forming an infant seat, because it does not form a simple rectangular box. The technique disclosed in Japanese Utility Model Laid-Open No. 57-153089 is one in which a rod is stretched to form a box. However, when the rod is attached to each plane, it is necessary to extend the whole circumference of the net to stretch the net on the rod and spot-weld it, which is very troublesome, the manufacturing cost is high, and it is not practical. Not.

In particular, the above-mentioned conventional technique does not disclose a technique of stretching a commercially available already formed net,
Since the wire rod is used in the manufacturing process, and as a result, a net in which the wire rods are substantially parallel to each other is formed, it takes time and effort to manufacture the wire rod.

Here, the net material already formed as shown in FIG.
It is conceivable to cut it as a character-shaped net material and stretch it on the frame. FIG. 5 is a front view of a net material that can be used for carrying a bicycle for infants.

When the front, rear, left and right sides and the bottom of the frame are covered by using a net having a substantially T-shape of this kind, as shown in FIG. It is necessary to cut it into a letter shape and bend it according to the shape of the frame. However, in this case, a special cutting die is required to cut the corner portion B of the net, and a large amount of the residual material C is produced.
The raw material cost, and eventually the manufacturing cost, increase, which is not preferable from the viewpoint of material cost and waste.

Therefore, the present invention can reduce the risk of falling even if the contained object is small, and even if it is attached to the bicycle, it does not impair the overall design, and further, it eliminates the waste of material due to its molding and the spot. It is an object of the present invention to provide a bicycle infant loader that has a low manufacturing cost by reducing the number of joints such as welding.

[Means for Solving the Problems] A bicycle infant carrier according to the present invention includes a front frame portion arranged in front of a luggage carrier of a bicycle, a bottom frame portion fixed to the luggage carrier, and a rear side of the luggage carrier. A rear frame part located at, a side frame part that is continuous with the rear frame part and that is located on the left and right sides of the cargo bed, and an open part between the front frame part and the both side frame parts.

A laterally long protective frame 31 in which a protective net 32 is stretched is attached to the side surface of the footrest member 30 to prevent the infant's foot from being caught in the rear wheel of the bicycle.

Next, the cutting of the front bottom net 6 and the rear net 16 of the bicycle for children according to the present embodiment configured as described above will be described.

In this embodiment, the front bottom frame 7 and the rear side frame 17 are separately formed, and the front bottom net 6 and the rear side net 16 each having a net material formed in a predetermined shape are stretched. In order to form the front bottom net 6, as shown in FIG. 2, one portion of the net mold X formed by cutting the net material into a substantially rectangular shape (a boundary portion between the bottom frame portion 1 and the front frame portion 2). Is bent into an L-shape, which is joined by spot welding or the like. Further, in order to form the rear net 16, as shown in FIG. 3, the net material is cut into a substantially rectangular shape, and the left and right upper end portions thereof are cut obliquely at two positions of the net type Y ( The portions corresponding to the boundaries between the both side frame portions 13 and 14 and the rear frame portion 15) are bent into a U-shape, which are joined by spot welding or the like.

It should be noted that the spot welding points can be reduced by joining one part of the mesh type X into an L shape by bending it and by bending two parts of the mesh type Y into a U shape. , Productivity is good.
However, in the case of a plurality of divided pieces, it is possible to cut without waste depending on the size of the net material having a rectangular plate shape.

In addition, in the present embodiment, as shown in FIG. 5, one mesh member A having a rectangular plate shape is not cut into a substantially T-shape in a plane and is bent according to the shape of the frame. , A special cutting die is required to cut the corner B of the net,
The problem that a large amount of residual material C is formed can be solved.
That is, as shown in FIGS. 2 and 3, the net type X and the net type Y, which are cut into a substantially rectangular shape, have a low material cost, and the material is not wasted.

Next, the use of the bicycle infant carrier of the present embodiment constructed as described above will be described.

The bicycle infant loader of the present embodiment having this type of configuration,
When used as a luggage compartment, both side frame parts 13,14
The opening / closing frame 24 is tilted toward the front frame 2 side to block the opening 25 by rotating the opening / closing frame 24 around the fulcrum at the bottom.

When placing an infant on the luggage basket, open and close the open / close frame 24.

Next, after the infant is seated on this basket and his / her feet are taken out from the opening 25 and placed on the footrest member 30, the safety belt 21 is placed in front of the infant's body.
Tighten and let the infant grasp the handle bar 3.

As described above, the child-carrying bicycle for bicycle according to the above-described embodiment uses the front bottom net 6 and the rear net 16 having the small rhombic mesh as the support for the contained items and the fall prevention. Therefore, even when a small or slender luggage is accommodated without having a gap extending in one direction between the wire rods as in the conventional bicycle infant loader, they are connected to the front bottom net 6 and the rear net 16 respectively. The risk of falling from the mesh is reduced.

Further, since the front child frame 7 and the rear frame 17 are separately formed and integrated with each other, the bicycle infant loader of the above-described embodiment is used for the mesh type X for the front bottom net 6 and the rear net 16. The net mold Y can be cut and formed separately.

Therefore, all the cutting can be performed linearly without providing the corner portions in the net mold X and the net mold Y described above, and a special cutting mold is not required for the cutting. Furthermore, only a very small amount of residual material y is generated in the cutting out of the net molds X and Y, and the raw materials that are wasted when the net material is cut can be minimized. Therefore, even when the net is used as a support for the contents, the raw material cost and hence the manufacturing cost in the bicycle infant manufacturing are reduced.

In addition, when the bicycle infant loader of the above-described embodiment is used as a luggage compartment, the opening 25 is shielded by the opening / closing net 28, so that there is almost no possibility that the stored luggage falls from the bicycle infant loader. In addition, since the bicycle infant loader of the above embodiment is provided with the handle bar 3, the safety belt 21, and the footrest member 30, it is possible to use these to stabilize the posture of the infant loader. it can.

In addition, the bicycle infant loader of the above-described embodiment is provided with the footrest member 30.
Since the protective frame 31 in which the protective net 32 is stretched is provided on the side of the child, the infant's pants or the like rarely protrude from the footrest member 30, and there is no risk that the infant will be caught in the rear wheel and injured the infant. .

Then, as shown in the drawing, the open portion 25 between the front frame portion 2 and the both side frame portions 13 and 14 can be freely opened and closed. The open / close frame 24 that is arranged to be positioned is such that the open / close frame 24 overlaps the left and right inner sides of both side frame portions 13 and 14 to increase the stability of the infant when placed on the left and right sides and further enhance the safety. You can

By the way, although the mesh material of the front bottom net 6 and the rear net 16 of the above-mentioned embodiment is a commercially available mesh shape of a rhombic wire mesh, the present invention is not limited to this when embodying the present invention. Instead, it may be anything as long as it functions to prevent the contained items, especially small contained items, from falling.

Further, the net material of the present embodiment does not mean a material that results in a net by welding a large number of wire rods. For example, the net material is preliminarily made into a net and its shape is a polygon of a triangle or more, or a circle. Any commercially available net such as an elliptical net may be used.

[Advantages of the Invention] As described above, the bicycle infant loading device according to the present invention has the front frame portion, the bottom frame portion, the rear frame portion, and the rear frame portions on both side frame portions located on the left and right sides of the infant frame or the contents. Of the open space between the front frame part and the both side frame parts is arranged to be openable and closable to select a closed space or an open space for mounting an infant or a contained object. A foot rest member arranged at the lower part of the open portion restricts the movement of the foot of the placed infant, and a handle bar arranged at the upper end of the front frame portion stabilizes the placed infant's body. Of the cushioning member accommodated in the space formed by the bottom frame portion, the front frame portion, both side frame portions, and the rear frame portion, to alleviate the vibration applied to the infant or the contents and to reduce the load. By making the distribution uniform, it is possible to prevent tired infants from getting tired and to prevent damage to the contained items. It can be lost.

Further, due to the substantially rectangular front bottom net stretched over the front frame part and the bottom frame part, and the substantially rectangular rear side net stretched over the both side frame parts and the rear frame part, the contents are dropped. It is possible to improve the stability of the bicycle in the case of receiving wind, and to reduce the fluid resistance such as the influence of cross wind, and to improve the modeling line of the bicycle body as a whole. It is modeled with similar lines and does not impair the design of the bicycle.

Therefore, since the substantially rectangular net is stretched over the front frame part and the bottom frame part, the both side frame parts and the rear frame part, by the way, there is no fear that they will fall even if the contents are small. Moreover, since it is possible to cut the raw material as a net having a substantially rectangular shape, it is not necessary to use a special cutting die, and waste of material can be eliminated, so that the manufacturing cost can be reduced. it can.

And, a substantially rectangular front bottom net continuously stretched to the front frame part and the bottom frame part, a substantially rectangular rear side net continuously stretched to both side frame parts and the rear frame part is continuous. Since it is stretched, the number of joints such as spot welding is reduced, and the cost required for processing is reduced.

Further, the open / close frame between the front frame part and the both side frame parts can be opened and closed freely. The opening and closing frames are overlapped on the inside of the left and right sides to increase the stability for the left and right when the infant is placed, and further enhance the safety. In addition, since this bicycle infant loader is provided with a protective frame in which a protective net is stretched on the side of the footrest member, infant pants or the like rarely protrude from the footrest member, and this is caught in the rear wheel. There is no danger of the infant getting injured,
Higher safety.
