Abstract
The utility model improves part of the structure of a roller case to provide the roller case with a self-running function, so as to realize walk substitution on a trip. When the roller case of the utility model is stored as a case, a handle stand pipe can be retracted into a front wheel stand pipe, and the whole front wheel assembly is embedded into an empty chamber of the case body. When the roller case of the utility model is used as a roller case, a handle rod is pulled out, and thus the case is pulled to move forward in a routine way. When the roller case of the utility model is used for walk substitution, the roller case is ridden; the handle is held slightly backwards with both hands, and front wheels and pedal rods protrude forward slightly; the pedal rods are stepped on with both feet; forward force is applied to the pedal rods; with the cooperation of the backward pulling by both hands, back wheels are driven by a pulling belt through pulling a belt wheel, a back roller, and a ratchet wheel to make the roller case move forward. The pulling belt retracts and winds the belt wheel under the action of a retraction coil spring by retracting both hands backwards and pulling both hands forwards. The above actions are repeated, and thus the roller case moves forward while carrying a person. When the front wheek assenbly moves forwards, the case body tilts slightly, and the case body is prevented from contacting the ground when made into an inclined plane.
Description
Technical field
The utility model belongs to the travelling Trolley case.
Background technology
The suitcase of band roller generally can only haul or shove along, but often has border, transfer stop distance longer in the travelling, and walking is wasted time and energy.
Summary of the invention
The utility model improves the part-structure of Trolley case, makes it that function voluntarily can be arranged, and rides instead of walk on the road.
There is the forward wheel components of similar ordinary bicycle the casing front, is made up of front-wheel, front fork, front-wheel standpipe, handle and stem.At the front-wheel standpipe two pedal strokes are arranged, an end of pull strap is connected on the pedal stroke, and the upper end of front-wheel standpipe and casing are hinged by hinge.
Rear wheel part be contained in casing below, belt wheel and retraction ring spring are arranged in the middle of the hind axle, there is bearings at two ends, be two trailing wheels outside the bearing, being equipped with in the trailing wheel and can making trailing wheel by the ratchet of unidirectional driving. pull strap is on belt wheel. and when belt wheel was rotated by the pull strap pulling, trailing wheel can advance by the driving rolls case.During the pull strap playback, even the counter-rotating of retraction ring spring hind axle.Ratchet in the trailing wheel can make trailing wheel still keep forward travel state under the situation of hind axle counter-rotating.
When the utility model was deposited as chest, stem can be withdrawn in the front-wheel standpipe, and whole forward wheel components also embeds in the space of casing.
When the utility model uses as Trolley case, pull out handlebar stem, can spur in a conventional manner and advance.
When the utility model uses as riding instead of walk, then ride Trolley case, both hands handle hand slightly backward, front-wheel and front fork, pedal stroke etc. are namely outstanding slightly forward, both feet are set foot on foot-driven lever, exert oneself forward, cooperate the both hands post-tensioning, pull strap namely drives trailing wheel by pulling belt wheel, hind axle, ratchet, and Trolley case is advanced.Receive both feet backs, push away before the both hands, pull strap namely under the effect of retraction ring spring reduction of area on belt wheel.Repeat above-mentioned action, Trolley case can manned advancing.
When forward wheel components travelled forward, casing can tilt to some extent, and the lower box beveling can prevent that it from contacting with ground.
Description of drawings: Fig. 1 is the utility model front view.
Fig. 2 is the utility model lateral plan, and wherein dotted line 13 is illustrated in the position that forward wheel components is released forward when using of riding instead of walk, the position when forward wheel components was accommodated in the case when dotted line 14 expressions were deposited as chest.This moment stem can retraction front-wheel standpipe in.
The specific embodiment:
There is the forward wheel components of similar ordinary bicycle casing (5) front, is made up of front-wheel (8), front fork (7), front-wheel standpipe (4), handle (1) and stem (2).At front-wheel standpipe (4) pedal stroke (6) is arranged, an end of pull strap (9) is connected on the pedal stroke (6), and the upper end of front-wheel standpipe (4) and casing (5) are hinged by hinge (3).
Rear wheel part be contained in casing (5) below, two trailing wheels (10) share a hind axle, there are belt wheel and retraction ring spring in the centre, there is bearings at two ends, being two trailing wheels (10) outside the bearing, being equipped with in the trailing wheel (10) and can making trailing wheel (10) by the ratchet of unidirectional driving. pull strap (9) is on belt wheel.When belt wheel was rotated by pull strap (9) pulling, trailing wheel (10) can advance by the driving rolls case.During the pull strap playback, even the counter-rotating of retraction ring spring hind axle.Ratchet in the trailing wheel (10) can make trailing wheel (10) still keep forward travel state under the situation of hind axle counter-rotating.
When the utility model was deposited as chest, stem (2) can be withdrawn in the front-wheel standpipe (4), and whole forward wheel components also embeds in the space (12) of casing (5).
When the utility model uses as Trolley case, pull out handlebar stem (2), can spur in a conventional manner and advance.
When the utility model uses as riding instead of walk, then ride Trolley case, both hands handle hand (1) slightly backward, front-wheel (8) and front fork (7), pedal stroke (6) etc. are namely outstanding slightly forward, both feet are set foot on foot-driven lever (6), exert oneself forward, cooperate the both hands post-tensioning, pull strap (9) namely drives trailing wheel (10) by pulling belt wheel, hind axle, ratchet, and Trolley case is advanced.Receive both feet backs, push away before the both hands, pull strap (9) namely under the effect of retraction ring spring reduction of area on belt wheel.Repeat above-mentioned action, Trolley case can manned advancing.
When forward wheel components travelled forward, casing can tilt to some extent, and lower box beveling (11) can prevent that it from contacting with ground.
