Description

{RACK OF THE TOWING BICYCLE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bicycle towing platform, and more particularly, to a bicycle towing platform including a towing device for towing another bicycle on a conventional bicycle platform.

Cars can be towed if they can not travel due to accidents or breakdowns, but bicycles must be towed by people or moved by car. If there is a problem with the bicycle in a place where the vehicle can not enter, the person should eventually be dragged or moved.

In this case, a bicycle towing device that is capable of towing a bicycle for use is disclosed in Japanese Patent Laid-Open No. 10-2010-0132602.

The connection method of the towing device is a type in which the seat post and the chain stay of the towing bicycle serve as levers and the towing device is connected to the front hub through the front wheel of the towed bicycle.

However, the connection between the towing bike and the towing bicycle is connected to the front hub of the towed bicycle. Only the bike with the spoke wheel can be connected. The plastic or special structure wheel can not be connected because the hub is not exposed. There are no bicycle hubs on each bicycle, so it is difficult to securely fasten the bike. Also, as the bike is connected to one side of the traction bike, the center of gravity moves to one side.

Also, it can not be used for other purposes except for traction, so it may be a little cumbersome to mount it on a flat surface.

In addition, Korean Utility Model Registration Nos. 294218 and 264729 and Korean Patent Laid-open No. 10-2008-0098699 allow connection of two or more bicycles by connecting the front bicycle and the rear bicycle to the front bicycle, Rear Bicycles There is a problem in that bicycles which are not used for special equipment can not be connected or towed.

An object of the present invention is to provide a bicycle traction loader which can be safely moved when a traction is required due to a breakdown or an accident of a bicycle while being used as a carrier of a bicycle in normal times.

In order to achieve the above object, a bicycle traction platform according to the present invention includes a plurality of height adjustment holes for height adjustment of a pulling mount, a platform support having a height adjustment groove formed therein, The traction mount is combined with the bottom of the vehicle. The platform is equipped with a wheel mount that can be mounted on a removable wheel of the traction bike.

In addition, although the carrier support may be formed in a circular shape, it is preferable that a plurality of height adjustment holes and height adjustment grooves are formed in the shape of an elliptical or polygonal column to prevent the rotation of the pull mount.

In addition, the towing mount is provided with a traction hole for connecting a bicycle, and the traction hole is coupled with the bearing to prevent bolt loosening due to the rolling between the bicycle and the bicycle during operation, .

In addition, it is preferable that the wheel base is adjustable in length by a sliding method in consideration of the wheel size of the bike to be towed, and it is preferable to adjust the mounting angle.

The conventional bicycle towing device is a method of pulling the bicycle by pulling it on the hub of the towing bicycle. The bicycle which is not exposed to the hub can not be towed and the size of the hub is different for each bicycle. It is difficult to securely fix the bicycle. However, in the traction method according to the present invention, by removing the wheels of the towed bicycle and connecting the towed bicycle to the center of the towed bicycle, the center of gravity It can be safely towed without tilting to one side and it can be used as a load carrier in normal times.

The present invention relates to a bicycle traction loader 100 which is coupled with a towing mount 20 for connecting a bicycle to a support 30 of a conventional bicycle loading platform and includes a wheel cradle 50 ).

3, a connecting portion 10 is provided in front of the bicycle traction platform 100 so that the bicycle can be mounted on the bicycle. The connecting portion 10 is formed by a seat-post mounting type like B and a seat clamp mounting type And the platform 40 and the connecting portion 10 have the structure of the joint 11 between A and a such that the angle can be adjusted according to the size and structure of the bicycle when mounted.

The support base 30 is assembled on both sides of the platform 40 and the lower end fixing holes 33 can be mounted on the rear hub bolt or a separate assembly groove.

A plurality of height adjusting holes 31 and height adjusting grooves 32 are formed on the support 30 so as to adjust the height of the pulling mount 20 according to the length of the front fork of the towed bicycle, The hole 31 is bolted to the pulling mount hole 22 like D and the height adjusting groove 32 is fixed to the QR lever 21 of the pulling mount 20 in conformity with the groove as d.

The support 30 may be formed in a circular shape, but may be formed in an elliptical or polygonal column shape to prevent rotation of the pull mount 20.

The pulling mount 20 has a support hole 25 through which the support 30 penetrates at one end as shown in FIG. 4 and a pulling mount hole 22 The bearing hole 23 is inserted into the traction hole 24 and the center hole 23-1 of the bearing 23 is inserted into the trailing hole 24, So that it can be connected to the bike with a towing bolt.

The bearing 23 is inserted into the traction hole 24 of the pulling mount 20 in such a manner that the bearing 23 is slightly wider than the width of the pulling mount 20 as shown in FIG. The bolt tightening hole 26 is screwed and tightened with the tightening bolt 16 so that the bearing 23 can be moved to the left and right as occasion demands.

In this case, the width of the dropout varies depending on the use of the manufacturer or the bicycle. In this case, when the left and right widths are adjusted by moving the bearing 23 or when the rear end is connected, the bearing 23 is moved It is easy to connect the bicycle to the bike if you match the width.

E is a view seen from the right side of the E portion. In the case of the front dropout 80, the width of the bearing 23 is smaller than that of the pulling mount 20, To the front dropout 80 (see FIG. 6), and in the case of the rear dropout 70, the bearing 23 is wider than the pulling mount 20 toward the outer side 23-70 And is connected to the push-out dropout 70 (see FIG. 7 in parallel)

In addition, the bearing 23 can prevent bolt loosening that may occur in the back and forth between the towing bicycle and the towing bicycle.

5, the wheel mount 50 is divided into a fixed portion 53 fixed to the platform 40, a mount portion 54 for mounting the wheel, and a slider portion 52 for adjusting the length .

One end of the fixing portion 53 is loosely fixed to the platform 40 with the assembly bolt 1 56 and is capable of being rotated upward and downward and has a fastening hole 57 for tightening with a slider adjusting bolt 58, .

Further, a mounting groove 51 for mounting the wheel is formed on the mounting portion 54 to fix the hub bolt of the wheel. The one end of the mounting groove 51 can be assembled with the slider portion 52, have.

A slider hole 55 is formed long from the center to the front side of the slider part 52 and a part of the mounting bolt 2 59 The angle of the mounting portion 54 can be adjusted.

With such a structure, normally, it can be used for the purpose of putting the load on the platform 40, and when the bicycle is towed, the back of the platform 50 can be lifted up to mount the wheel 60 removed from the bicycle. The angle can be adjusted so that it can be mounted regardless of the size of the wheel.
