Abstract

The utility model relates to a folding handle for bicycles, which is composed of an upright pipe of the folding handle for bicycles, a clamp seat, a quick disassembly handle and two transverse handles. The clamp seat is fixed to the upright pipe of the folding handle for bicycles. The left and the right ends of the clamp seat are respectively provided with notches. The front and the back parts of each notch are respectively provided with a round through hole and a threaded hole. Two holes are in an identical horizontal axis line. One surface of the round through hole is provided with a dissecting groove. One surface of the clamp seat is provided with a penetrating round hole. The quick disassembly handle is penetrated through the penetrating round hole. One end of each transverse handle is provided with an elliptical hole which is respectively assembled in the notches of the left and the right ends of the clamp seat by a bolt. A user can wrench forwards or backwards the quick disassembly handle. Consequently, the two transverse handles are in the state of swing or suspended placement to obtain the purpose of saving space.

Description

A kind of collapsible handlebar

The utility model relates to a kind of collapsible handlebar.

As shown in Figure 1, general common bicycle handle is one through car body vertical tube B and the cross handle A that is fixed thereon, and the user controls the direct of travel of car body C by control cross handle A.Yet most of users think after using: because surpassing the edge of overall width, cross handle A total length puts, and when parking space is very narrow, very inconvenient; And, also, the user is felt deeply puzzlement because so very take up room.

In view of the foregoing, the purpose of this utility model provides a kind of collapsible handlebar of saving the space.

For achieving the above object, the utility model adopts following design plan: a kind of collapsible handlebar, and it is made of handlebar vertical tube, holder, quick detach handle and two cross handles; Described handlebar vertical tube is fixed on the car body; Described holder is fixed on the handlebar vertical tube; At the left and right two ends of described holder one breach is arranged respectively; An one circle perforation and a tapped bore arranged respectively on the forward and backward both sides of breach, and circle is bored a hole and tapped bore is same horizontal axis; Outer rim is a profile groove on circle perforation one side; Have one to run through circular hole on one side of described holder; Described quick detach handle is through the described circular hole that runs through, and locatees by double-screw bolt; Described two cross handles are assembled in the breach at the left and right two ends of holder respectively by bolt; One end of cross handle has an elliptical aperture.

When assembling, at first, elliptical aperture is alignd with the circle perforation and the tapped bore at breach two ends, then, a bolt is passed the elliptical aperture of cross handle and the circle perforation at breach two ends, and located; After the combination, the quick detach handle is pulled forward or backward, profile groove on the holder is compressed or lax, raise or the lowering state thereby make two cross handles be pendulum, to reach the purpose of saving the space.

Further specify below in conjunction with accompanying drawing.

Fig. 1 is the three-dimensional assembling of a common handlebar scheme drawing.

Fig. 2 is the utility model installation site scheme drawing.

Fig. 3 is the utility model perspective exploded view.

Fig. 4 is the three-dimensional combination of a utility model scheme drawing.

Fig. 5-A is the utility model quick detach handle operation scheme drawing.

Fig. 5-B is that the utility model two cross handles are and fold view.

Fig. 5-C is the folding back of the utility model two a cross handles block diagram.

The utility model is applicable to various car bodies, and as Fig. 2, Fig. 3, shown in Figure 4, it is that holder 2 left and right two ends on the handlebar vertical tube 11 of car body 1 respectively are provided with a breach 21; At breach 21 a forward and backward circle perforation 22 and one tapped bore 23 that are respectively equipped with, circle perforation 22 and tapped bore 23 are same horizontal axis; One side outer rim in circle perforation 22 is a profile groove 24; Have in a side of holder 2 and always to fasten hole 25; Place for the double-screw bolt 31 of a quick detach handle 3 and to run through circular hole 25 and screw togather location (shown in Fig. 5-A) with nut 3; A cross handle 4 is assembled at breach 21 places respectively at holder 2 left and right two ends, one end of this cross handle 4 is shaped on an elliptical aperture 41, after the circle perforation 22 at the elliptical aperture 41 of two cross handles 4 and breach 21 two ends and tapped bore 23 alignd, located (as Fig. 4, Fig. 5-C) by bolt 4A.

So, when handlebar vertical tube 11 set up fixing after, cross handle 4 and vertical tube be 11 vertical, quick detach handle 3 is pulled forward, the profile groove 24 of holder 2 is compressed downwards, paste stagnant, in conjunction with the location, supply user's gripping to control car body 1 (as Fig. 2); When parking maybe need fold, then quick detach handle 3 is pulled open backward, make the profile groove 24 of holder 2 be not close to compressing, be relaxation state that (as Fig. 5-A), then cross handle 4 is pulled outward, cross handle 4 is that pivot is nature lowering state (shown in Fig. 5-B, 5-C) with bolt 4A just.With the folding of two cross handles 4 folding after, saved the bicycle occupation space.

Because the utility model adopts above design plan,, use convenient parking and during other special requirement, having saved the bicycle occupation space.
