Abstract
The invention relates to a bicycle which is provided with a front fork riser and a handlebar. The handlebar and the front fork riser are actively connected with each other, and a locking mechanism which can lock the handlebar and the front fork riser is arranged, which can be a lock; a lock body of the lock is arranged below the handlebar; a lock-tongue hole matched with the lock-tongue of the lock is arranged on the front fork riser; the direction of the lock-tongue and the lock-tongue hole is along radial direction of the front fork riser; the lock has two or three locking positions and one position is determined when an extension direction of the handlebar is vertical to a front wheel and another one or two positions are determined when the extension direction of the handlebar is parallel to the front wheel. The bicycle effectively reduces the occupied area where the bicycle is parked and meanwhile has the antitheft effect. The invention has simple complete operation process so as to be beneficial for promotion and utilization.
Description
Technical field
The present invention relates to a kind of bicycle.
Technical background
Bicycle is the common vehicle, cheap, easy to use and help advantage such as healthy to be liked by people with it always, particularly since in recent years urban highway block up day by day and air pollution problems inherent that automobile brings serious day by day, bicycle is considered as the vehicle that should advocate energetically by people especially.But the use of a large amount of bicycles has also brought the problem of parking the place anxiety, in order to reduce the floor area of bicycle parking, people have proposed many solutions, for example No. 200320110285.1 patents of invention of China disclose a kind of contraction type bicycle handle bar, this patent is divided into three sections with bicycle handle bar, peg graft or be socketed on the interlude for left and right two sections, and fixing between realizing three sections by the latching device that is located at each junction.When needs are parked, open latching device, two sections are laminated on the vehicle body it about the rotation handlebar, have reduced the width that bicycle handle bar takies thus, that is have reduced the floor area of bicycle on Width.The major defect of this technology is to carry out the folding and expansion of handlebar, uses inconvenience.
Summary of the invention
For overcoming the above-mentioned defective of prior art, the invention provides a kind of bicycle, this bicycle floor area of handlebar when parking is little, and easy to use.
The present invention realizes that the technical scheme of above-mentioned purpose is: a kind of bicycle, be provided with vertical tube of front fork and handlebar, and described handlebar and described vertical tube of front fork flexibly connect and be provided with can be with the lockout mechanism of both lockings.
Described lockout mechanism is lock or pin mechanism, and described handlebar adopts the rotary connection mode with the flexible connection between the front fork standpipe.
Described handlebar central authorities are provided with upright hole and are enclosed within the upper end of described vertical tube of front fork, free-running fit between the two.
The pin seat that the lock body of described lock or be used to is installed pin is positioned at the handlebar below.
Described vertical tube of front fork is provided with dead bolt hole that matches with the dead bolt of described lock or the pin hole that matches with described pin.
Described dead bolt hole or pin hole are set directly on the tube wall of described vertical tube of front fork, and dead bolt hole seat or pin hole seat perhaps are set on vertical tube of front fork, and described dead bolt hole or pin hole are arranged on the dead bolt hole seat.
The direction of described dead bolt, pin, dead bolt hole and pin hole be vertical tube of front fork radially.
There are two or three latched positions in described lock or pin mechanism, and one of them position is the position of handlebar bearing of trend when vertical with front-wheel, and another one or two positions are the position of handlebar bearing of trend when parallel with front-wheel.
The quantity of described dead bolt hole or pin hole is two or three.
The dead bolt of described lock is axially movable columnar member.
Principle of work of the present invention and beneficial effect are: during use, open lock earlier, handlebar can be rotated with respect to vertical tube of front fork, the position (the handlebar bearing of trend is vertical with plane, front-wheel place) when rotating handlebar to cruising also locks it on the vertical tube of front fork; During bicycle parking, open lock earlier, rotate handlebar and make its bearing of trend parallel, and then handlebar is locked together with the front fork standpipe with lock with the front-wheel direction.Floor area when having reduced bicycle storing effectively thus also plays antitheft effect simultaneously, and all operating process is all very simple, helps promoting the use of.
Description of drawings
Fig. 1 is the local structure scheme drawing of one embodiment of the invention.
The specific embodiment
Below, adopting lock with lockout mechanism is example, describes embodiments of the present invention in detail.
Referring to Fig. 1, the invention provides a kind of bicycle, be provided with vertical tube of front fork 1 and handlebar 2, described handlebar and described vertical tube of front fork flexibly connect and be provided with can be with the lock of both lockings.
Described handlebar can adopt the rotary connection mode to connect with the flexible connection between the front fork standpipe.For example, described handlebar central authorities are provided with upright hole and are enclosed within the upper end of described vertical tube of front fork, and free-running fit between the two is to realize the rotation of handlebar with respect to vertical tube of front fork.Can realize the location of handlebar on vertical tube of front fork is axial by modes such as the shaft shoulder on the vertical tube of front fork, the axle collar and the nuts that spins, move up and down to avoid handlebar.
The lock body 3 of described lock can be positioned at the handlebar below, and is fixedly mounted on the described handlebar by modes such as welding.Described vertical tube of front fork is provided with the dead bolt hole that matches with the dead bolt 6 of described lock, the direction of described dead bolt and dead bolt hole be vertical tube of front fork radially.
Described dead bolt hole can be set directly on the tube wall of described vertical tube of front fork, also the dead bolt hole seat can be set on vertical tube of front fork, and dead bolt hole is arranged on the dead bolt hole seat.
Described lock can have two or three latched positions, one of them position is the position (the during cruising relative position of handlebar) of handlebar bearing of trend when vertical with front-wheel, and another one or two positions are the position (when the depositing position of handlebar on Width shared width minimum) of handlebar bearing of trend when parallel with front-wheel.Adopt this radially mode of locking to help simplified structure, but according to actual needs, the axial locking mode that also can adopt dead bolt and dead bolt hole to extend up and down.
For realizing two or three latched positions, as long as two or three dead bolt holes are set, the relative position that makes dead bolt insert the dead bolt hole rear bar is in the desired position just.Can use key 4 rotational lock cores 5 during use, and then drive the dead bolt action.
The concrete form of described lock and structure can adopt various suitable prior aries or in the future possible technology, its diverse location that passes through of described dead bolt general reference different shape and structure is realized locking and the part of opening, the columnar member of preferred various can moving axially (bearing of trend that refers to axial or this part of this part itself itself here) is to improve intensity and reliability.
When lockout mechanism adopted pin mechanism, its basic structure can be similar with the basic structure that adopts lock.Described pin mechanism can adopt prior art, mainly by pin, install pin mounting hole and with the supporting pin hole of pin, pin mounting hole and pin hole lay respectively at two parts (handlebar and front fork column) that need locking.In the pin mounting hole, can be provided with pin supporting with the outside compression spring on top of pin so that automatically pin is pressed in the pin hole under lock-out state, the pin outer end can be provided with handle, so that pin is pulled out in pin hole when needing.
