CN203806055U - Foldable schoolbag rack for foldable bicycle - Google Patents

Abstract

The utility model relates to a bicycle and concretely relates to a foldable schoolbag rack for a foldable bicycle. The upper ends of supports (5) are connected to the lower surface of the schoolbag rack (4) via a group of rotating shaft; the lower ends of the supports (5) are connected with the back end of a back fork (6) of a bicycle frame via a group of rotating shaft; the front end of the schoolbag rack (4) is connected with the upper end of a seat tube (2) via a group of rotating shaft; and reinforcement is added between the two supports, so the two supports are combined into an integral body.

Description

A kind of folding bicycle folding schoolbag holder

Affiliated technical field

Relate to bicycle, be specifically related to the folding schoolbag holder that a kind of folding bicycle is used.

Background technology

My patent of the same name (seeing the patent No. 200920178818,7 specification sheetss) " with the sleeve pipe of one group of rotating shaft connecting vehicle frame, connects and supports with one group of rotating shaft below before schoolbag frame, support the back vent with one group of rotating shaft connecting vehicle frame again." this patented technology is when launching due to bicycle; the position of sleeve pipe be landing in the lower end of sitting pipe, position is on the low side, schoolbag frame cannot do height; the radian rotating with crank due to the heel of human body; the more than half part of the schoolbag frame side that just accounted for, so, although solved folding problem simultaneously;; this schoolbag frame can only carry few thing, at all cannot be manned, so-called pleasnt to the eye but of no use.This schoolbag frame is exactly due to folding movable, more easily twisting, and wigwag motion, can aggravate along with the time using and frequency.

Summary of the invention

Below (seeing Fig. 1) schoolbag frame (4), connect and support (5) upper end with one group of rotating shaft (all " one group of rotating shaft " here and below all refers to each one of left and right limit conventionally), support the rear end of (5) lower end with the back vent (6) of one group of rotating shaft connecting vehicle frame, the front end of schoolbag frame (4) connects the upper end of sitting pipe (2) with one group of rotating shaft.

This method of attachment, according to the well known practice of custom, sits pipe (2) upper end and must add an attaching parts with fixed rotating shaft, and then the front end of schoolbag frame (4) can be connected with seat pipe (2).So, here sitting that (fixedly hold, slotting) between pipe (2) and saddle pipe (3) be connected is exactly an attaching parts, if a rotating shaft of the each composition in the screw two ends of this attaching parts, can save parts, make it more succinct (as shown in Figure 1).

" sitting the upper end of pipe (2) " of above-mentioned indication, comprises the midway location of sitting pipe (2) until all different point of connection of upper end position.The height of schoolbag frame (4), can improve with the positioning and lifting of point of connection, declines with the decline of point of connection location, and same, the point of connection on back vent is also that schoolbag frame is larger more backward.So its location is depended on needs and feasibility completely.

Between two supports (5), having increased a shape is three leg-of-mutton joint pieces (seeing Fig. 3), has strengthened its stability.Certainly, this joint piece also can use sheet material.

Brief description of the drawings

Fig. 1: schoolbag frame expansion drawing simultaneously on bicycle, in figure schoolbag frame be supported for " fourth " word shape;

Fig. 2: schoolbag frame is while folding picture on bicycle, and in figure, schoolbag frame and supported folding become " // " (parallel).

Fig. 3: upper section part back view of support.

In figure, pipe, (3) saddle pipe (4) schoolbag frame, (5) support, (6) back vent, (7) joint piece are sat in (1) sleeve pipe, (2).In figure, the rotating shaft of vehicle frame part represents with stain, and the rotating shaft of schoolbag frame part represents with white point, to show difference.

Specific embodiments

Here adopt before schoolbag frame and change and become " the seat pipe upper end of connecting vehicle frame " to do height with one group of rotating shaft " sleeve pipe of connecting vehicle frame "; Change into connection " rear end of back vent " to do greatly supporting again with " back vent " of rotating shaft connecting vehicle frame.Like this, just make whole schoolbag frame raising increase many, finally make schoolbag frame can play real effect, such as will carry a thing, pick a kindergarten or child at primary school etc. temporarily, bring more convenience to our life.Aspect solution twisting, independently increasing a joint piece that adds strong stability between two supports mutually, they are coupled to and are integrated.

This schoolbag frame can be applicable to patent 200820105361,2 and patent 200920149518,6 two kind of folding bicycle support the use.

Claims (2)

1. the folding schoolbag holder that folding bicycle is used, below schoolbag frame (4), connect and support (5) upper end with one group of rotating shaft, it is characterized in that supporting the rear end of (5) lower end with the back vent (6) of one group of rotating shaft connecting vehicle frame, the front end of schoolbag frame (4) connects the upper end of sitting pipe (2) with one group of rotating shaft.

2. schoolbag frame according to claim 1, is characterized in that two are independently supported between (5) and increased a joint piece, are coupled to them and are integrated.
