Abstract
The utility model discloses a tricycle roller skate, including the shoes body, three pulleys are installed respectively to the centre at the front portion of the sole of shoes body, middle part, rear portion, and the planar distance of sole is arrived to the minimum limit that the planar distance of sole is greater than anterior pulley and rear portion pulley in the minimum limit that is located the middle part pulley, anterior pulley is one -way pulley. The utility model has the advantages of taxiing speed soon, can not influence other people, laborsaving.
Description
Technical field
The utility model relates to sports apparatus field, especially relate to a kind of sliding speed fast, other people, labour-saving three-wheel roller skate can not be affected.
Background technology
Roller skate, ice skate, being a kind ofly utilize special roller skate for the sports of instrument of competing, is also a kind of toy of daily leisure.The acceleration of roller skate is that a pin slides, and another pin is pedaled after tiltedly, thus produces a component forward, but this mode of advancing, at the rink that people is more, certain obstacle that can produce other people action, simultaneously because power thrusts and the direction of motion are inconsistent, also comparatively expend bodily strength.
Utility model content
For solving the problem, the utility model object be to provide a kind of sliding speed fast, other people, labour-saving three-wheel roller skate can not be affected.
The utility model is realized by following technical measures, a kind of three-wheel roller skate, comprise shoes body, the centre at the front portion of the sole of described shoes body, middle part, rear portion is separately installed with three pulleys, the minimum limit being positioned at middle part pulley is greater than the distance of minimum limit to sole plane of front pulleys and rear pulleys to the distance of sole plane, described front pulleys is unidirectional pulley.
As a kind of preferred embodiment, described spring heel is provided with one slightly lower than the anti-skid structure of the minimum limit line of middle part pulley and rear pulleys.
As a kind of preferred embodiment, described anti-skid structure is a rubber blanket being fixed on spring heel.
The utility model in use, because the minimum limit of middle part pulley to be greater than the distance of minimum limit to sole plane of front pulleys and rear pulleys to the distance of sole plane, like this when quick sliding, just middle part pulley is at taxiing, and front pulleys and rear pulleys are unsettled, only have pulley contact ground, middle part like this, thus can the speed slided be improved, the flexibility ratio to turn to etc. in sliding can also be improved.Front pulleys is set to unidirectional pulley simultaneously, when needs accelerate, a pin is only needed to slide, the tiptoe of another pin is kicked backward, because front pulleys can not rotate backward, thus and between ground, produce a reaction force forward, this mode is accelerated, do not need pin to the oblique outside motion on two limits, thus one is to increase the aesthetic property slided, two is to avoid because pin is to the action obstacle produced them during the oblique outside motion on two limits, and three are pin is firmly consistent with power direction, can save muscle power.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Contrast accompanying drawing below in conjunction with embodiment the utility model is described in further detail.
A kind of three-wheel roller skate, please refer to Fig. 1, comprise shoes body 1, the sole 6 of described shoes body 1 is provided with front pulleys 2, middle part pulley 3 and rear pulleys 4, the minimum limit of middle part pulley 3 is greater than the distance of minimum limit to sole 6 plane of front pulleys 2 and rear pulleys 3 to the distance of sole 6 plane, described front pulleys 2 is for making the proal unidirectional pulley of shoes body 1.
This roller skate in use, distance due to the minimum limit to sole 6 plane that are positioned at the middle part pulley 3 at middle part is greater than the distance of minimum limit to sole plane of front pulleys 2 and rear pulleys 4, like this when quick sliding, just middle part pulley 3 slides with earth surface, and front pulleys 2 and rear pulleys 4 are unsettled, only has middle part pulley 3 kiss the earth like this, thus can the speed slided be improved, the flexibility ratio to turn to etc. in sliding can also be improved, certainly when starting or the time of turning to or dangerous time or the time of being unfamiliar with, also front pulleys 2 or rear pulleys 4 can be allowed also simultaneously and earth surface, increase security.Front pulleys 2 is set to unidirectional pulley simultaneously, when needs accelerate, a pin is only needed to slide, the tiptoe of another pin is kicked backward, because front pulleys 2 can not rotate backward, thus and between ground, produce a reaction force forward, this mode is accelerated, do not need pin to the oblique outside motion on two limits, thus one is to increase the aesthetic property slided, two is to avoid because pin is to the action obstacle produced other people during the oblique outside motion on two limits, and three are pin is firmly consistent with the direction of motion, can save muscle power.
At the three-wheel roller skate of the present embodiment, please refer to Fig. 1, the basis of previous technique scheme can also be specifically, sole 6 heel is provided with one slightly lower than the anti-skid structure 5 of the minimum limit line of middle part pulley 3 and rear pulleys 4.When slowing down or stop, when having been stood on tiptoe by a pin, make the anti-skid structure 5 on this pin and ground friction, thus carried out slowing down or stopping.
At the three-wheel roller skate of an embodiment, please refer to Fig. 1, the basis of previous technique scheme can also be specifically, anti-skid structure 5 is a rubber blanket being fixed on spring heel.
More than that the utility model three-wheel roller skate is set forth; the utility model is understood for helping; but embodiment of the present utility model is not restricted to the described embodiments; any do not deviate from the utility model principle under do change, modification, substitute, combination, simplify; all should be the substitute mode of equivalence, be included in protection domain of the present utility model.
Claims (3)
1. a three-wheel roller skate, it is characterized in that: comprise shoes body, the centre at the front portion of the sole of described shoes body, middle part, rear portion is separately installed with three pulleys, the minimum limit being positioned at middle part pulley is greater than the distance of minimum limit to sole plane of front pulleys and rear pulleys to the distance of sole plane, described front pulleys is unidirectional pulley.
2. three-wheel roller skate according to claim 1, is characterized in that: described spring heel is provided with one slightly lower than the anti-skid structure of the minimum limit line of middle part pulley and rear pulleys.
