Description

Carrying frame buffer

The present invention relates to a bicycle carrying frame, and more particularly to a carrying frame with a cushion to prevent deformation of the bracket tube of the coupling device due to stress.

The bicycle carrying frame is a device that can be coupled to the vehicle and can be used to position at least one bicycle on the carrying frame, and the bicycle can be fixed on the carrying frame and can be reached with the vehicle. Farther away. The general carrying frame is provided with a combination device for connecting with the vehicle, and the carrying frame is connected with the combined device. When the bicycle is fixed on the carrying frame, the weight of the bicycle and the carrying frame itself is bound by the bracket of the device. The tube is tolerated. When the vehicle travels through an uneven road surface, the entire carrying frame together with the bicycle will move up and down. At this time, the bracket tube on the combined device is subjected to additional force, and is generally required to carry the frame and the binding device. Lightweight, most of the tubes are made of aluminum material. The material is soft in texture, so when additional force is applied to it, there is fear of deformation. Once the bracket tube is deformed, it is stressed. The ability is drastically reduced, and finally the rupture of the stent tube is not inadvertent.

The present invention is directed to the above-mentioned lack of designing a cushioning device comprising a cushion disposed between the coupling device and the tubular body of the carrier frame to absorb the force generated by the vibration, so that the force is not transmitted to the binding device. The stent tube is protected to protect the stent tube from deformation and damage.

The present invention is a carrier frame cushioning device comprising a coupling device coupled to a vehicle connector, the two bracket tubes extending from both sides of the coupling device for pivotal connection with the carrier frame. A receiving member is coupled to the bonding device and forms a receiving space. The carrying frame has a frame body, and the two rod bodies are connected between the opposite first side tubes and the second side tubes of the frame body. The two bracket tubes are pivotally connected to the two rods, so that the carrier frame can be lifted up by the pivot joints of the two bracket tubes and the two rods as a rotating shaft. A plurality of positioning elements are provided on the carrier frame to position the bicycle on the carrier frame. The first side tube is accommodated in the receiving space. A cushion is received in the receiving space and is located between the first side tube and a wall surface of the receiving member and forming the receiving space. A positioning device connects the first side tube to the coupling unit, and thereby restricting the first side tube from being located in the accommodation chamber. When the vehicle passes through an uneven road surface, the first side tube is protected by the cushion without being affected by the impact force, thereby protecting the bracket tube from deformation.

Referring to the first to fourth figures, the carrier frame cushioning device of the present invention comprises a coupling device 10 having a coupling unit 11 for coupling with a vehicle connector (not shown), and the coupling unit 11 can be any The conventional type will not be described here. Two stent tubes 12 extend from both sides of the binding device 10. A slightly C-shaped receiving element 13 is connected to the joining device 10 and forms a receiving space 131, and an inverted U-shaped piece 132 is attached to the bottom surface of the receiving element 13.

A carrier frame 20 has a slightly rectangular frame body 21, and the two rod bodies 22 are connected between the opposite first side tubes 23 and the second side tubes 24 of the frame body 21. Two sets of positioning elements 25 are disposed between the two rod bodies 22 and the tube bodies at both ends of the frame body 21 to position the wheels of the bicycle. A vehicle body positioning member 26 is pivotally disposed between the two rod bodies 22 to position the frame of the bicycle. The two bracket tubes 12 are pivotally connected to the two rod bodies 22 respectively, so that the carrier frame 20 can be lifted up by the pivotal connection between the two bracket tubes 12 and the two rod bodies 22 as a rotating shaft, which will be described later. The first side tube 23 is closer to the coupling unit 10 than the second side tube 24, and the first side tube 23 is received in the accommodating space 131. An extension portion 231 protrudes outward from the first side tube 23.

A cushion 30 is provided with one or a plurality of recesses 31 for engaging the recesses 133 of the recesses 31 on the receiving member 13 to be received in the receiving space 131 and located at the first side tube 23 and The element 13 is received and formed between the wall faces of the accommodation space 131. The cushion 30 can be fixed to the wall surface of the accommodating space 131 by bolts as shown in the seventh figure. As shown in the eighth figure, the cross section of the groove 31 of the cushion 30 is combined with the rib 133 of the receiving member 13.

A positioning device connects the first side tube 23 with the coupling unit 10, and thereby restricts the first side tube 23 from being located in the housing chamber 131. The positioning device includes a bolt 40 extending from the bottom surface of the receiving member 13 through the inverted U-shaped piece 132 and passing through the receiving member 13 and the extending portion 231 to be coupled with a nut 41 to restrict the first side tube 23 Located in the accommodating space 131. The head of the bolt 40 abuts against the inner side surfaces of the inverted U-shaped piece 132 to form a good positioning function.

As shown in the fifth figure, the nut 41 can be screwed to secure the bolt 40, and the nut 41 can be loosened to separate the nut 41 from the bolt 40, so that the user can carry the carrier 20 The pivotal connection between the two bracket tubes 12 and the two rod bodies 22 can be lifted upwards, so that the rear door of the vehicle can be opened, and the whole payment carrier frame 20 does not need to be detached from the vehicle, and the operation is extremely convenient. It is only necessary to separate the nut 40 from the bolt 40, and any user can quickly achieve the purpose of pivoting the carrier 20.

As shown in the sixth figure, when the vehicle travels through an uneven road surface, the carrier frame 20 is subjected to the vibration to cause the first side tube 23 to be pressed against the cushion pad 30 so that the additional impact force is not transmitted. To the two stent tubes 12, the stent tube 12 is protected from deformation.

The present invention can absorb the force of the vibration by the arrangement of the cushion 30, so that the carrier frame 20 and the bracket tube 12 are properly protected, and the carrier frame 20 and the bracket tube 12 which are made of a softer and lighter material are used. The lack of improvement has been made, and the invention has met the patent requirements, please request a patent.
