Lateral trailer for bike

 

(57) Abstract:

Usage: in the field of transport, in particular for single-track vehicles, bicycles, mopeds and. so on the inventive side bike trailer includes a support frame including transversely spaced elements 1, 2, 3, associated with the attachment points to the frame of the bike. On the lower transverse elements 1 and 2 installed floor 7, forming with the latter and the frame of the bike main frame. The attachment points of the transverse elements are located on the frame of the bike under his saddle, on the axis of the rear wheel of the bike and on the lower end of the rod 10 attached to the Bicycle frame. The trailer allows you to increase the mobility transformation bike without holding perevalochnij works. 5 C.p. f-crystals, 5 Il.

The invention relates to vehicles, particularly to hand trucks and trailers for single-track vehicles bicycles, mopeds, etc.

Known technical solution [1] in which the truck-trailer is mounted on the frame of the bike instead of the rear wheels and flap, thereby rendering a two-wheeled bike tricycle.

This technical solution has a significant drawback requires the issue is the group and the closure of the chain, that reduces the mobility of the transformation of the bike and increases labor costs.

The closest in technical essence to the proposed invention is a technical solution, where lateral trailer mounted close to the bike with clamps, with the upper part clings specially installed on the bike rear trunk.

This technical solution has the disadvantage that the necessary movement of the legs when pedaling requires to move the trailer back, which causes her mount to the rack, but weak rigidity of the trunk to the side effort leads to weak fastening rigidity of the trailer and reduce the weight of the cargo carried in it.

The closest is the side of the trailer bike, containing resting on the wheel support frame including two transversely spaced element, and associated with the frame of a Bicycle by means of attachment points [3]

The downside of it is the lack of reliability of attachment to the Bicycle frame.

The task, which is aimed by the invention is the creation of new, more reliable device.

This trailer is equipped with additional cross the om, forming, together with an additional cross member and the frame of the bike main frame, and the frame of the bike in its vertical plane of the fixed bar, located behind the front wheel of a Bicycle, with the attachment points of the transverse support frame elements are located respectively on the lower end of the specified rod and the axis of the rear wheel of the Bicycle, and the attachment of additional cross member is located on the frame of the bike under his saddle.

In addition, the rod is placed on the mount can be mounted on side of the Bicycle frame vertically and attached with clamps to the frame, a rod mounted on side of bike frame inclined and attached the clamps to the frame, the bottom bar is installed on the Bicycle frame horizontally and attached the clamps to the chain pipe plug rear wheels, mount located under the saddle to the Bicycle frame, is a plate mounted on the jumper plug rear wheels, to which by means of bolts attached additional transverse element having grooves, which are placed in the fork of the rear wheel; the attachment of one of the cross support frame is a plate, devenyi view of the trailer Assembly with the bike, side view of Fig. 2 is a top view of Fig.3 trailer, side view; Fig.4 is the same, top view; Fig. 5 is the same, end view.

The trailer is structurally made of rigid frame having two lower 1, 2, and one of the top 3 transverse load-bearing elements, which end with the attachment points to the frame of the bike. On the frame of the bike are special fasteners 4, 5 and 6, the attachment point of the rear wheel of the bike, under the seat and behind the front wheel on a special rod to which are attached cross-power elements 1, 3, 2 respectively. Thus is obtained a hard, closed-loop design in which the frame of the bike plays the role of hard power element of the trailer. Hard power floor 7, mounted on the lower transverse reinforcing elements 1 and 2, gives the design of the trailer even greater rigidity, allowing you to carry the maximum (in terms of load on the bike wheel) weight of the cargo. This design does not require installation (removal) of the trailer to dismantle any of the nodes of the bike. Additional nodes installed on the bike for connecting the side of the trailer, are stationary, do not require dismantling and do not interfere with operation of the Bicycle in the absence of the trailer. wheel bike. Rod 10 may be mounted on side of the Bicycle frame vertically and attached to the latter by means of clamps. Rod 10 may be attached to the Bicycle frame and inclined, and can be placed in the bottom of the frame horizontally and attached to the chain pipe plug rear wheels. Node 5 mount is located under the saddle to the Bicycle frame and is a plate that is installed on the jumper plug rear wheels, to which by means of bolts attached to the transverse element 3, made with grooves, which are placed in the fork of the rear wheel. Node 4 mounting cross member 1 is a plate, worn on the axle of the rear wheel of the Bicycle and secured by a nut of fastening of a wheel.

The trailer allows you to extend the capabilities of a standard road bike in terms of transportation of cargo. It allows you to increase the mobility transformation bike when removing and installing the side of the trailer on the bike without perevalochnij works. In the construction trailer makes maximum use of standard Bicycle parts and stationary mounted on the bike special fasteners.

1. Lateral trailer for bike, containing based on the number of the m mount, characterized in that it is provided with an additional element transversely located with the mount, and mounted on the transverse elements of the base frame to the floor, forming, together with an additional cross member and the frame of the bike main frame, and the frame of the bike in its vertical plane of the fixed bar, located behind the front wheel of a Bicycle, with the attachment points of the transverse support frame elements are located respectively on the lower end of the specified rod and the axis of the rear wheel of the Bicycle, and the attachment of additional cross member is located on the frame of the bike under his saddle.

2. The trailer under item 1, characterized in that the rod is placed on the mount is installed in the side of the Bicycle frame vertically and attached with clamps to the frame.

3. The trailer under item 1, characterized in that the bar is installed in the side of the Bicycle frame inclined and attached the clamps to the frame.

4. The trailer under item 1, characterized in that the bottom bar is installed on the Bicycle frame horizontally and attached the clamps to the chain pipe plug rear wheels.

5. The trailer under item 1, characterized in that the attachment point located on the second by means of bolts attached additional transverse element, having grooves, which are placed in the fork of the rear wheel.

6. The trailer under item 1, characterized in that the attachment point of one of the cross support frame is a plate that fits around the axle of the rear wheel of the Bicycle and secured by a nut of fastening of a wheel.
