Description

Rain-proof civer mounted on bicycle

The utility model is used for bicycle and covers rain and daylight.

Bicycle rider now more uses rain cape to hide rain, and not only permeability to air is poor, and face is dampened easily, and especially the bottom is easily rolled by wind, has increased the probability of traffic accident takes place, and can not be used to cover daylight.Existing at present many patents about the bicycle rain insensitive devices, mainly comprise umbrella clamper, special type " bicycle umbrella " and awning cover, but mostly exist to some extent to than the screening performance deficiency of driving rain, inadequately attractive in appearance, use operation quite not easy, laterally or overall dimensions bigger than normal or portable not enough etc.Along with the development of social civilization and the quickening of rhythm of life,,, all have higher requirement to the good looking appearance of bicycle rain insensitive device and easy-to-use performance as traffic view and convenient using appliance.

The purpose of this utility model be produce attractive in appearance, water-resistant performance is strong, easy to use, comfortable, have a certain portable bicycle rain insensitive device of good safety, collapsible tool.

The utility model is achieved in that on cycle frame installs a pair of grip block (1) near the front shaft sleeve place, grip block top is connected with an eye-splice (2), be used for pegging graft fast and shirking, eye-splice comprises connecting element and shirks part, connecting element and grip block join together and are fixed on the vehicle frame, shirk the part top and connect a support that can rotate up and down (3), the action radius of support becomes the approximate vertical shape to horizontality by its principal plane from close eye-splice, when support turns to the horizontal limeit position, dead bolt on the support (17) inserts eye-splice by spring force and shirks in the locking hole of part, support is fixed on this position, the a pair of fork arm (4) that can do locking phase to folding is installed on the support, when fork arm is flared to extreme angles, the back end housing of support stops it to continue outwards to rotate, lock protruding (18) on the support takeoffs under the spring force effect simultaneously, the bubble flare of fork arm is fixed on this angle, a collection spoke device (5) all is equipped with in the end of two fork arms, be fixed on two collection spoke devices by two ends of the bearing pin (31) on the collection spoke device one group of elastic spokes (6), be sewed with the hitch that equates with spoke quantity radially on the half ellipsoidal surface outer cover made from soft waterproof material (7), the spoke made from elastomeric material more than two penetrates wherein and connects with it, spoke becomes arch under the clamping of collection spoke device, make whole outer cover open the back and become semielliptical shape, the outer cover front portion has an observation window (8), a hoist cable all is equipped with at last root spoke place of first spoke of outer cover front end and rear end, the former links to each other with support at (10), the restriction outer cover rotates backward, the latter (11) can be buckled on the bicycle schoolbag frame, to strengthen the wind loading rating of whole device, also have a button (16) on the support, be used for the above-mentioned release that acts on the lock protruding (18) of fork arm and act on the dead bolt (17) of support.During use, the pulling spoke can open outer cover, otherwise then outer cover draws in; When needs are received, press the button (16), the lock protruding (18) that at first is contained on the push button shaft sinks, make the fork arm can be closed, continue by tight button, then another cam (19) that is connected on the push button shaft retracts the dead bolt (17) of lock bracket, the support by gravity rotates, whole device is received and is fallen within the vehicle frame front portion, pulls up eye-splice (2) at that time, can take off and can shirk part; As want pocket cover bicycle, and first spoke can be widened, make it to cover headstock, fasten the button of grabbing between observation window two end spokes, then all the other spokes are drawn back to the tailstock, then bicycle is all covered to schoolbag frame from headstock, and the bicycle behind the pocket cover takes up space not have obviously and increases; As under the outer cover open configuration, pulling up eye-splice, with eye-splice shirk part as hand holding handle, can hand use.

Observation window in the utility model (3) is topped transparent meshwork, rises and bears spoke pulling force and decoration function, and the observation window below is provided with a water retaining cover (9), is used to prevent that raindrop from seeing through observation window and injecting.

The hovel of observation window in the utility model (8) also can be the soft and transparent waterproof material, and the below is not provided with water retaining cover, to adapt to the demand high and not higher to the performance requriements that keeps out the wind to gas permeability requirements.

The structure of fork arm in the utility model (4) and be with the connecting mode of support (3): it is curved that fork arm has arc, can vacate the space of cyclist's arm activity, every fork arm root is equipped with one to two plate gear sheet (20), and be drilled with circular hole, have a pair of pin hole on the support simultaneously, pin (21) is fixed on two fork arms on the support, under the effect of engagement gear piece, when pulling wherein a fork arm, two fork arms are done relative open and close movement, and when fork arm was flared to extreme angles, the back-end support shell blocks gear piece to be continued outwards to rotate, lock protruding (18) on the support takeoffs under the spring force effect simultaneously, and the bubble flare of fork arm is fixed.

Elastic spokes in the utility model (6) is to make with the equal plastics of the resilient metal strip coated outside cross-sectional shape of unequal section; Earlier make thin bar with elastic metallic, two ends are drilled with circular hole, one section distance that is slightly less than collection spoke device radius is left in circular hole center to end, to strengthen the grip of collection spoke device to spoke, the circular hole part is arranged and lean on the cross section of end to be-shape, adjacent with it one section cross section is L shaped, centre portion is middle narrow two hem widths-tee section, spoke with this feature is convenient to superimposed in pairs being installed in the collection spoke device, both can reduce many spokes and be installed in same axle and go up gross thickness, and can make again that spoke is stressed to keep bigger radius of curvature and intensity preferably near two end parts when crooked; The centre portion of bonding jumper is wrapped in the identical oval plastic strip of cross-sectional shape with the part in L shaped cross section, select suitable sectional dimension, can make spoke when fork arm opens, form needed arch and when fork arm draws in, take less space, spoke after the injection moulding has improved the ability of anti-accidental shock and bending, owing to formed even and bigger flakiness ratio, spoke has good bearing along the performance of outer cover peripheral force.

The utility model can adopt following collection spoke device (5) structure: collection spoke device is made of carriage (29), middle clamp plate (30), bearing pin (31) and two limit clamping plate (32), carriage is connected fork arm (4) and goes up and support middle clamp plate, fork arm is made left rotation and right rotation relatively, with adapt to fork arm separately or when closed collection spoke device and fork arm with angle change, bearing pin passes the center of middle clamp plate, two limit clamping plate are installed in middle clamp plate two sides and link with bearing pin and carriage, are linked in preceding half cover of outer cover or the spoke of later half cover and are installed in middle clamp plate two sides respectively.
