Abstract

<P>PROBLEM TO BE SOLVED: To diminish a baggage basket in a single operation and to avoid hindering taking in/out of a bicycle when baggage is not put in the baggage basket while the baggage basket is fixed to the bicycle, for example when parking the bicycle in a bicycle parking lot. <P>SOLUTION: Front and rear sides and the bottom of the baggage basket are formed of members split into a strip shape joined with odd hinges and are constructed so as to be foldable in a single operation. Specifically, for example, the width of the strip-like center members in the front and rear sides and the bottom, for example, is made two times or more of that of the other members, the strip-like center member of the bottom is attached to a rack of the bicycle as a fixing member to the bicycle, and foldable moving members including the center member in the bottom are separated from the front and rear sides and are prolonged so as to stick out from the outer surface of the front and rear sides. In folding, adjacent strip-like members are folded on top of the strip-like center member of the bottom in a state that right and left parts of the bottom are held upward, the strip-like center members in the front and rear sides are pushed inward and folded so as to form the inner side of the baggage basket, and the width (and the volume) reduces to approximately one third. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

  The present invention relates to a structure of a storage box such as a luggage for a bicycle.

  Bicycle luggage is mainly made of plastic or metal, and is usually used firmly fixed to the front or (and) the rear of the bicycle.

  As a folding luggage, a rear luggage (Patent Document 2) has been proposed, but it is often used for a front luggage (see, for example, Patent Document 1), and this front luggage is usually suspended from a handle. Therefore, instability during use is a problem.

  In addition, most of the bicycle cargoes currently on the market are firmly fixed to the bicycle for safety and cannot be easily removed, but there are also cargoes having a detachable detachable structure.

  However, there is no cargo bag that can be folded while keeping the bicycle fixed while the storage capacity is variable.

  The larger the bicycle luggage, the more convenient it can cope with the increase or decrease of the load, but it is not easy to remove, and conversely, the luggage may get in the way.

  In particular, when parking at a bicycle parking space in a small space, the width of the cargo in the left-right direction is often obstructing, making it difficult to put in and out the bicycle.

  Folding cargo has been considered to solve these problems, but the existing folding cargo can be compressed in the front-rear direction and the height direction, so the dimensions in the left and right (lateral) directions do not change. Was difficult.

  Therefore, if the luggage can be folded in such a manner that the lateral width of the luggage can be reduced while attached to the bicycle, the above-mentioned problems can be solved at once, and safety during traveling can be achieved.

  In particular, in a bicycle parking lot, there is basically no luggage stored in the luggage, so if there is a luggage capable of reducing the lateral width of the cargo, the above problem can be solved.

In order to solve the above problems, it is necessary to fold the bicycle in the left-right (lateral) direction with the luggage attached, and to make the size of the luggage variable.

  Therefore, in the present application, in a cargo bag composed of a bottom surface portion and a side surface portion surrounded by four vertical and horizontal directions, the bottom surface portion and the lateral side surface portion can be folded so that the storage capacity of the cargo bag can be changed.

  Specifically, the bottom surface of the cargo box is divided into a plurality of strip-shaped members in the lateral direction to form a hinge connection. For example, in the case of five divisions, the central strip-shaped member is fixed to the bicycle and another strip-shaped member is used. The width of the bottom surface is reduced by folding the member.

  In this case, if the width of the strip-shaped member other than the strip-shaped central member is set to be half or less of the central member, the strip-shaped members adjacent on the central member can be folded and stacked from the left and right, and the lateral width can be reduced to a third. It can be shortened to near one.

  The side surface portion when the bottom surface portion is folded can be divided into strip-like members hinged like the bottom surface portion to have a folded structure, or a detachable structure.

  The above solution is basic, and plastic can be easily used as a material to be used as well as a wire mesh material which is widely used at present. Further, the range of reduction / enlargement can be further expanded by increasing the number of divisions of the bottom portion.

  Since the cargo bag of the present invention can be easily folded, when there is no cargo, it can be folded small to eliminate inconvenience when parking or running, ensuring safety, and not only for bicycles, but also for shopping carts, Can be widely applied to storage boxes, containers, etc.

FIG. 1 (a) is a perspective view, FIG. 1 (b) is a plan view, and FIG. 1 (c) is a side view before folding of an example in which the bottom and side portions of the folded cargo box are divided into five parts. The perspective view in the middle of folding of the example which divided the bottom face part and side part of the folding luggage into 5 parts FIG. 3 (a) is a perspective view, FIG. 3 (b) is a plan view, and FIG. 3 (c) is a side view. FIG. 4 (a) is a side view, FIG. 4 (b) is a rear view before folding, and FIG. 4 (c) is a rear view after folding. The perspective view in the middle of folding of the example which divided the bottom part of the folding luggage into 3 parts and the side part into 5 parts

  Divide the bottom part of the cargo into odd-numbered strip-shaped members to be hinged, and the central strip-shaped member is fixed with a screw hole etc. to fix it to the bicycle, and it is a strip-shaped member other than the central strip-shaped member The width of the member is set to half or less of the width of the central member (excluding both outermost strip members).

  The shape of the side surface portion can leave the shape of the cargo as a folding method similar to that of the bottom surface, and can also take a method of collapsing the shape of the cargo.

  A structure in which both side surfaces perpendicular to the direction in which the bottom surface portion is folded are divided into an odd number of strip-shaped members as in the bottom surface portion to be hinged, and when the bottom surface member is folded, the side members are also folded at the same time. By taking the above, it is possible to obtain a cargo with variable capacity.

  In addition, when folding without leaving the shape of the cargo, provide detachable joints on both side surfaces that are perpendicular to the direction in which the bottom surface is folded, fold it on the adjacent side surface, and place it on the side of the bicycle on the side of the bottom surface. Can be folded from the outside end.

  The above form is a case where it is attached to the rear part of the bicycle, but in the case of the front part, the center member of the odd-numbered strip-shaped member that is hinged on the opposite two side surface parts is firmly coupled with the strip-shaped center member of the bottom part, The strip-shaped members on the other side surface and the bottom surface are separated from each other.

  One of the two side strip-shaped central members is used as a mounting and fixing part at the front of the bicycle, the left and right strip-shaped members on the bottom are folded downward, and the left and right strip-shaped members are folded inward on the cargo box. The cocoon is reduced.

One embodiment of a bicycle rear luggage carrier according to the present invention is shown in FIGS.

The bottom surface portion 1 is divided into a central member 10 and five strip-shaped members 11, 11 ′, 12 and 12 ′, and the connection between the member 10 and the member 11 (11 ′) is an inward folding hinge connection, The connection between the member 11 (11 ′) and the member 12 (12 ′) is an outwardly hinged connection.

The width of the bottom surface members 11 and 11 'is less than half of the width of the member 10, and the widths of the members 12 and 12' are equal to or greater than the width of the members 11 and 11 'plus the thickness of the side surface.

The lengths of the members 10, 11, and 11 ′ are the same as the cargo width (the distance between the outer surfaces of the front and rear side surfaces), are separated from the side surface portion 3 (3 ′), and the side surface portions 3 ( 3 ') is provided with a guide projection 7 for preventing the spread to the outside.

The side surface portion 3 (3 ′) is divided into five strip-shaped members like the bottom surface portion, and the connection between the member 30 (30 ′) and the members 31 (31 ′) and 32 (32 ′) is an outward folding hinge connection, and the member 31 (31 ′) and the member 33 (33 ′), and the member 32 (32 ′) and the member 34 (34 ′) are inwardly hinged.

Further, the members 12 (12 '), 5 (5'), 34 (33) and 34 '(33') are coupled to each other and integrated.

The bottom member 10 is fixed to the fixed end of the bicycle, and as shown in FIG. 2, the side surface parts 5 and 5 ′ are lifted upward to fold the bottom member 11 (11 ′) onto the member 10 and the side member 31 ( 31 '
) And 32 (32 ′) are folded on the inner surfaces of the members 33 (33 ′) and 34 (34 ′) to form the shape shown in FIG. Can be.

On the outer side surfaces of the side members 33 (33 ') and 34 (34') when folded, mutual fixing metal fittings are provided and usually fixed.

In addition, although this application showed the specific example as a cargo bag loaded on a bicycle carrier, it is fixed to a fixed end (in the case of a bicycle, a carrier) with a certain width and fixed in a certain direction (in the case of a bicycle, the width direction of the bicycle). ) Is a proposal for a box that can be extended and retracted (in the case of bicycles, cargo).

If you want to keep the shape of the box, even if you do not have a fixed end, or if you want to keep it down, for example in a children's toy box, when you are playing with toys, shrink it, and when you finish playing and put it away It can be used to store a toy to make it a habit of tidying up, or a storage box placed in an empty space in a car.

In addition, the spread of bicycles loaded with cargo will make it easier to put in and out of bicycle parking lots, so a business model that encourages loading of cargo can be considered.
