Description

Trailer frame

This creation is a trailer frame that provides a bicycle that is not equipped with a tripod when parked.

Bicycles as a short-distance commute are a convenient means of transportation. Today, a variety of cycling competitions have also been developed, and it has become an easy-to-use sports and leisure appliance for the public.

Generally speaking, bicycles are mostly used in the rear fork of the frame, or the tripod is installed near the five-way pipe, and the foot kicker is swung in use so that one end of the tripod can contact the ground to park the bicycle. However, bicycles for special purposes are not equipped with the aforementioned tripods, such as racing or off-road sections, etc., in order to avoid collision with others during riding, fall over themselves, or accidentally entangle the tripod and forest vine plants. When the vehicle is out of control, the tripod will cause two injuries. Even the special-shaped frame is not easy to have a tripod. Therefore, most of the frames having the aforementioned use or appearance-specific bicycles are not equipped with a stand.

Bicycles that do not have a tripod are required to use additional parking frames, parking racks and other related equipment to park the bicycles that are parked. The common parking frame has two U-shaped knots arranged by the top and bottom of the "Bicycle Parking Frame" designed by Taiwan No. D172824. Constructed to support the rear fork position of the bicycle frame. However, this type of type cannot be adjusted in height, and it is a common type. It is difficult for consumers to favor the new and demanding changes, especially for those who like to try new products.

In this regard, the above-mentioned bicycle additional use parking equipment, the development and design of related products, after many trials and trials, finally created a new type of product, not only can be used to adjust the height, but also has its unique use. Can effectively attract the attention of consumers and then purchase.

This creation provides a new type of use of the trailer frame, and the height adjustment can be changed according to the size of the bicycle.

In order to achieve the foregoing objects and effects, a trailer frame is provided, including a base, an elevator platform, and an adjustment button, wherein: the base has an axial through hole and a side hole connected to the through hole at one side; The lifting platform includes a lifting rod, an abutting rod and a hanging seat; the supporting rod includes an assembling portion, and a bent portion integrally connected with the assembling portion; the assembling portion of the engaging rod and the upper end of the lifting rod The lower end of the lifting rod is telescopically displaced in the perforation, thereby controlling the distance between the base and the abutting rod and the hanging seat, and the adjusting hole is inserted through the side hole to be positioned at the lifting rod circumference. a side portion; a protruding portion extending outwardly from the assembly portion, the hanging seat is movablely disposed on the protruding block, and the hanging seat has a hanging surface for hanging the rear fork of the frame, and the bending The portion has a curved abutting surface for abutting the inner side of the upper fork behind the frame.

Referring to Figures 1 through 3 of the drawings, the trailer frame 1 is shown, including a base 2, an elevator table 3, and an adjustment button 4.

The base 2 has a through hole 21 in the axial direction and a side hole 22 connected to the through hole 21 on one side.

The lifting platform 3 includes a lifting rod 31, an abutting rod 32 and a trailer seat 33. The abutting rod 32 includes an assembly portion 321 and a bending portion 322 integrally connected with the assembly portion 321; the abutting rod The assembly portion 321 of the 32 is assembled with the upper end of the lifting rod 31, and the lower end of the lifting rod 31 is telescopically displaced in the through hole 21, thereby controlling the distance between the base 2 and the abutting rod 32 and the hanging seat 33, and The adjusting button 4 is disposed on the side of the lifting rod 31 by the side hole 22; the assembling portion 321 of the abutting rod 32 extends outwardly with a protrusion 323, and the hanging seat 33 is movablely disposed on the protruding portion Block 323, again The trailer seat 33 has a hanging surface 331 for hanging the rear fork of the frame, and the curved portion 322 has a curved abutting surface 320 for abutting the inner side of the upper fork of the frame.

It can be seen from the above description that the present trailer frame 1 provides the bicycle's rear fork hanging type with the trailer seat 33, and the curved upper surface of the curved portion 322 abuts the bicycle's rear upper fork inner position, which is different from The type of bicycle parked in the conventional parking frame. Furthermore, the present invention provides that the adjustment position of the lifting platform 3 relative to the perforation 21 can be moved by loosening the adjustment knob 4 (see the fourth and fifth figures) without moving against the top side of the lifting rod 31. After the height is removed from the ground, the adjusting knob 4 is tightened to be pressed against the circumferential side of the lifting rod 31, so that the size parking position suitable for the bicycle can be adjusted. According to this, in addition to the size of the bicycle frame, tires and other factors, the present invention can adjust the appropriate height to park the bicycle, and has a special way of abutting the bicycle and the upper fork with the curved portion 322, thereby achieving the adjustment factor of the creation. A trailer frame 1 for bicycle size changes and a new type of use.
