Abstract
The utility model relates to a manpowered stair-ascending six-wheel cart with auxiliary wheels, which comprises a six-wheel cart and auxiliary wheels. The six-wheel cart comprises a box body, an axle, an axle sleeve, a cart handle and six wheels; the three wheels at each side not only are in a self-rotation shape through the support of the fulcrum shaft of the axle sleeve but also in a revolution shape through the sleeving relation of the axle sleeve and the axle; each auxiliary wheel comprises an outer ring, a central hub and elastic spokes, and a plurality of elastic spokes with similar performance are arranged between the central hub and the outer ring; and the auxiliary wheels are sleeved on the axle of the six-wheel cart in a rotatable type through the central hub. When a six-wheel cart without the auxiliary wheels is pulled to ascend stairs and if the steps of the encountered stairs have higher height or narrow width, the fulcrum shaft of the axle sleeve is led to be in contact pressing or slide friction with the stair outer edges when the six-wheel cart is climbing the stairs. If the six-wheel cart with auxiliary wheels is applied, when the six-wheel cart encounters the same stair situations when ascending the stairs, the rotary auxiliary wheels can perform the function of wheels. Obviously, the six-wheel cart with auxiliary wheels brings much more convenience to people for carrying objects to ascend stairs.
Description
Affiliated technical field
The utility model relates to a kind of hand buggy, the manpower of often using in the especially old resident's daily life six wheeler of going upstairs.
Background technology
As everyone knows, many people in cities and towns stay in the residential building, come from every day shopping need people to invent can to lean on manpower pulling six wheeler upstairs.The axle sleeve that is with three fulcrums of shape all can be rotating on the axletree of this each side of car, and a runner is housed all on each fulcrum of axle sleeve, each side all had two wheels to land when this car was walked on the level land like this, if car runs into stopping of banquette when operation, the wheel on the another one fulcrum then can be substituted at any time with the form of revolution so.Self-evident, just because this each side has the six wheeler of three wheels that such motion characteristics has been arranged, it has just had the function of going upstairs.Yet, in the middle of the process that this six wheeler of application is gone upstairs, it is found that it has such deficiency: in case some discrepancy of the design of the height of stairway step, width and this six wheeler the time, six wheeler no longer is that wheel lands, but pressing or cliding friction of its fulcrum position of axle sleeve and its outer edge of stair appearred, obviously this is a kind of breaking-up to six wheeler and stair.In order to address this problem, the present invention improves this six wheeler: promptly, add on its axletree and overlapped the jockey pulley that a kind of its spoke has resilient characteristic, release a kind of manpower that has jockey pulley six wheeler of going upstairs thus.Find no the invention of identical structure by retrieval.
Summary of the invention
The objective of the invention is: release a kind of six wheeler upstairs that is applicable to various stair situations.
A kind of manpower that has jockey pulley six wheeler of going upstairs, it is made of six wheeler (1), jockey pulley (2); Six wheeler (1) is made of casing (10), axletree (11), axle sleeve (12), wheel (13), wheel (14), wheel (15), car handle (16), the support by these three fulcrums of axle sleeve (12) radially uniform three fulcrums on it, the wheel of each side (13), wheel (14), wheel (15) can be the rotation shape and again nested relationship and the axletree (11) by axle sleeve (12) and axletree (11) be the revolution shape; Jockey pulley (2) is constituted, and be provided with the close elasticity spoke (22) of several performances between center hub (21) and outer ring (20) by outer ring (20), center hub (21), elasticity spoke (22); Jockey pulley (2) is rotary shape by center hub (21) and is sleeved on its axletree of six wheeler (1) (11).
Beneficial effect of the present invention: released a kind of manpower that is applicable to plurality of specifications stair six wheeler of going upstairs to people.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model structural representation.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the six wheeler structural representation among Fig. 1.
Fig. 4 is the jockey pulley structural representation.
Fig. 5 presses or view during cliding friction for the fulcrum of its axle sleeve of six wheeler and stair outer edge are.
Among each figure, 1, six wheeler, 10, casing, 11, axletree, 12, axle sleeve, 13, wheel, 14, wheel, 15, wheel, 16, the car handle, 17, stair, 2, jockey pulley, 20, the outer ring, 21, center hub, 22, the elasticity spoke.
The specific embodiment
The utility model as shown in Figure 1 is made of six wheeler (1), jockey pulley (2); The wheel (13) of each side of six wheeler (1), wheel (14), wheel (15) both can be by axle sleeve (12) but support be the rotation shape, nested relationship and the axletree (11) by axle sleeve (12) and axletree (11) is the revolution shape again; Jockey pulley as shown in Figure 4 (2) is provided with the close elasticity spoke (22) of several performances between center hub (21) and outer ring (23); And jockey pulley (2) is rotatable state by center hub (21) and is nested with on its axletree of six wheeler (1) (11).
When people's pulling does not have the six wheeler of jockey pulley (2) to go upstairs, if the height of its step of stair (17) of running into is higher or width when narrower, six wheeler (1) no longer is that wheel lands when climbing the building, but as shown in Figure 5: cause pressing or cliding friction of its fulcrum of its axle sleeve (12) and stair (17) outer edge.On the contrary, if people use the six wheeler (1) upstairs the time that jockey pulley (2) are housed, if when running into the situation that height is higher or width is narrower of its step of stair (17), even six wheeler its be provided with wheel and can not land, so, rotary jockey pulley (2) can be born the effect of wheel.Obviously, the six wheeler that has jockey pulley (2) brings bigger convenience upstairs for people's loading.Simultaneously, because jockey pulley (2) is provided with elasticity spoke (22), therefore, this six wheeler has the adaptive capacity of very strong height aspect.
Claims (1)
1, a kind of manpower that has jockey pulley six wheeler of going upstairs, it is made of six wheeler, jockey pulley; Six wheeler is made of casing, axletree, axle sleeve, car handle and six wheels, and three wheels of each side both can be the rotation shape by the support of its fulcrum of axle sleeve, and nested relationship and the axletree by axle sleeve and axletree is the revolution shape again; It is characterized in that: jockey pulley (2) is constituted, and be provided with the close elasticity spoke (22) of several performances between center hub (21) and outer ring (20) by outer ring (20), center hub (21), elasticity spoke (22); Jockey pulley (2) is rotary shape by center hub (21) and is sleeved on its axletree of six wheeler (1) (11).
