Fixing the longitudinal rod for bike with attachments

 

The invention relates to connecting elements for securing wheelchairs or similar devices for bicycles. The device is a sliding tubular rod having spaced at the ends of the attachment points of attachments and their own mounts to the bike: the mount to the carriage and the attachment point to the axis of the rear wheels. The mount to the axis of the rear wheels is made in the form of end retaining rings (3) with a hole (7) for fastening it to the axis of the rear wheels and with holes (4) for fastening the hinged equipment, such as side or rear of the trailer. The front shank (2) rod also serves for fastening the hinged equipment - side of the trailer. The proposed solution is aimed at providing fixed in the side of the stroller and the rear of the trailer. 2 C.p. f-crystals, 10 ill.

The invention relates to a Bicycle with trailer stroller - rear or side - trailers or any other attachments, and specifically to the intermediate elements for fastening mentioned trailers or attachments.

Currently known associated with Bicycle intermediate elements for fastening the side pri.05.92 (application) mounting rod, built-in closed bike frame and rigidly fastened with a seatpost rack and the bottom tube of the frame. A rod equipped with the ability to rotate the tubular clamp associated with the trailer. This solution is complex and unreliable attachment of the trailer to the terminal through the swivel clamp and screw to limit rotation of the clip.

Closest to the invention is a technical solution according to European patent EP 0.949.140 from 31.03.99,, CL B 62 K 27/00 priority from Germany 09.04.98, whereby the mounting of the longitudinal rod to bike with attachments (lateral trailer) is a rod with a shank for mounting attachments and means mounting the rod on the axis of the rear wheel and the Bicycle frame having a cross carriage and feather chain fork.

The latest technical solutions closest to the invention made as a prototype.

The disadvantage of the prototype is that the rod is complicated in shape and the attachment to the frame too close - they are placed on the bottom side of the lower frame tube and under the axle of the rear wheel-side opposite the location of the trailer. The connection of the trailer frame with a rod carried is authorized with the end of rod hinge.

The aim of the invention is the creation of a multi-purpose device rather simple design, combined with any bike frame that enhances the performance properties of any bike.

For this purpose the rod is provided with a terminal connected with curly earring mounting with holes for its attachment to the axis of the rear wheels and for accession by the hinged equipment, in this case the rod is equipped with a fixing unit for fixing the frame to the cross carriage and can be equipped with a control node.

In addition, the consolidation of the rod on the frame to the cross carriage implemented rigidly connected with the rod support bracket for supporting the cross carriage and coupling screw with the upper bracket to the elastic contraction of the mentioned support bracket and pen chain fork, and a rod connected with curly mounting earring articulated through a tip.

The rod may be connected with curly mounting earring tough, and fixed to the cross carriage is carried out covering the body of the spider and tightened between the upper bracket and lower bracket having an eyelet for attachment of a rod.

The goal is indeed possible, because first of all the violence, acting on the Bicycle, fall directly on the rear wheel; secondly, the longitudinal rod is easy to install on the bike with any frame - open or closed, with the crossbar of the carriage, and relies on the axle of the rear wheel of the Bicycle; thirdly, the longitudinal rod can be installed on both the left and the right side of the bike, which allows to use the trailer on both left and right sides, respectively; and, finally, fourth, the installation of two rods (left and right) we will provide a reliable device for the collection of the rear truck.

Declared fixing the longitudinal rod coupler bike, having a shank for mounting attachments and means mounting the rod on the axis of the rear wheel and the Bicycle frame with the carriage and feathers chain fork, which is characterized by the fact that the rod is equipped with terminal mounting earring with holes for its attachment to the axis of the rear wheels and for accession by the hinged equipment, in this case the rod is equipped with a fixing unit for fixing on the carriage or on the feathers chain fork, and the node to adjust the rod length.

In one embodiment, the rod can support bracket, interacting with the carriage at the expense of the clamping screw with the upper bracket for tightening the support bracket and feather chain fork, while between the support bracket and feathers chain fork can be placed elastic element.

In another embodiment, the rod can be connected to the mounting ring rigidly and fixed to the carriage performed covers the body of the carriage and pulled between the upper bracket and the lower bracket with eyelet for fastening the fastening of the longitudinal rod.

A specific implementation of fastening of the longitudinal rod by, for example, the following ornia mounted equipment, and the second end of the curly ends of the fastening ring 3 having openings 4, to attach the rear or side mounted equipment, such as trailers. The rod 1 has a regulating unit 5 to adjust the length of the rod 1 and the fastening means 6 on the frame of the bike, which can be done in two different ways.

Common to these methods is that the bike mounting rod 1 is attached through the hole 7 in figure mounting the earring 3 under the axle of the rear wheel of a Bicycle, and that to the frame of the bike it is attached through the cross carriage.

The first view of the harness fastening of the rod 1 on the frame of the bike is directly connected with the body of the spider 9 carriage and consists of rigidly connected with the pivot 1 bracket 8, which is based on a body of the spider 9 carriage bike. The bracket 8 is a platform, on which, apart from the body of the spider 9 carriage rests elastic element 10 placed between the bracket 8 and feathers 11 chain fork of a Bicycle. On top of the feathers 11 chain fork is a bracket 12, and the resulting package is pulled coupling screw 13, is placed in a through hole 14 passing through the bracket 12, the gap between the feathers 11 chain fork, the second connection terminal 1 with shaped fastening ring 3 through the tip of the rod 15 and the hinge 16.

The second type of node consolidation of the longitudinal rod 1 on the frame of the bike also focuses on the crossbar 9 of the carriage and includes an upper bracket 17 and the lower bracket 18 and covers the body 19 of the spider 9 carriage and rigidly drawn between the fasteners. The bottom bracket is made zuzelo with an eye 20 for installation of beam 1 and fixing it.

The second type of fastening of the rod 1 on the bike is provided a rigid connection rod 1 with an earring 3. A variation of the second mounting rod 1 to the Bicycle frame contains the eyelet 21 made zuzelo with the lower bracket 18, and is associated with the ear 22 on the beam 1. The lug 21 is composed of a bracket 23 rigidly connected with the sleeve 24 under the fastener.

The work proposed rod in any way secure it is very simple. Using a regulating unit 5, expose the desired length of the rod 1 so that the hole 7 in figure mounting the shackle 3 is aligned with the axis of the rear wheel of the bike and the mount to the crossbar aligns with seats on the body cross members 9 of the carriage.

Then fix the axis 7 of the Bicycle by means of the threaded fasteners, and then either tighten the clamping screw 13, in the case with mounting brackets 12 on top of the coefficients, tightening the top 17 and bottom 18 of the bracket, case mounting rod 1 to the housing 19 of the spider 9 carriage through the eyelet 20 or sleeve 24 made zuzelo with the lower bracket 18 and covers the body 19 of the spider 9 carriage from below.

The bracing of equipment are carried out by the holes 4 in figure fastening ring 3 and the shank of the rod 1.

The use of the inventive rod allows any bike with any frame to convert the bike from the rear or side placement of attached equipment, such as trucks, only by attaching to the bike such a rod.
