Abstract

An automatic shoes rotator, in order to solve the technical problem, adopts follow technical scheme. When a foot-operated button is trodden, the vertical movement of the button is converted into the horizontal movement of a tooth bar by a slope on the lower portion of the button. In above process, since a ratchet in a gear matches with the tooth bar, the gear is in idle run and a rotating disk does not rotate when the button is pressed down. The horizontally moving tooth bar compresses a spring at the tail end for accumulating energy. When the foot-operated button is released, the tooth bar drives the rotating disk coaxial to the gear to rotate under the effect of the energy-accumulated spring. When the tooth bar moves, a positioning latch is drawn down/released through a roller-way, so that the rotating disk is locked under stationary state and accurately rotates 180 degrees under action. Under a stationary state, the rotating disk remains absolute stationary by the positioning latch. The rotation speed of the rotating disk is controlled by adjusting the pre-tightening force of the energy-accumulated spring. A latch mechanism correlated with the position of the tooth bar controls the rotating disk to accurately rotate 180 degrees each time.

Description

Automatically turn the footwear device

Technical field

The present invention relates to turn footwear device field, be specifically related to a kind of utilize that mechanical mechanism rotates reverse slippers automatically turn the footwear device.

Background technology

A slippers are generally placed separately in toilet and kitchen at home in the city, the water and the foreign material that prevent toilet and kitchen surface take on the room floor by slippers, but because the direction of travel during turnover toilet/kitchen is opposite, slippers are always oppositely placed when changing slippers, for the old man who walks with difficulty, passing in and out in this case the toilet extremely wastes time and energy, and also falls down easily.So automatically turn footwear apparatus by what design can be placed on the doorway, overcome the old man in the wet and slippery situation in the ground such as toilet, bathroom, in the small space, turn round the circumstances of wearing footwear inconvenience, reduce the possibility that the old man falls down under the analogue, improve the convenience degree of life.

Summary of the invention

The utility model utilizes mechanical mechanism to rotate reverse slippers, overcomes the old man in the wet and slippery situation in the ground such as toilet, bathroom, in the small space, turns round the circumstances of wearing footwear inconvenience, reduces the possibility that the old man falls down under the analogue, improves the convenience degree of life.

The technical scheme that its technical problem that solves the utility model adopts is: after foot push is operated, moving both vertically of button is converted into the horizontal movement of tooth bar by the slope of button bottom.In this process, because the gear inside that cooperates with tooth bar is ratchet mechanism, thus in the process of button down, gear idle running, rotating disk does not rotate.The tooth bar compressed ends spring energy-storage of horizontal movement.When foot push unclamped, tooth bar drove the dial rotation coaxial with gear under the effect of energy-storaging spring.In addition, the fastening screw that utilizes roller-way to leave behind/decontrol when moving by tooth bar, 180 ° of accurately rotations of rotating disk when realizing the locked and action of mechanism's inactive state lower rotary table.

Automatically the footwear utensil that turns of the present invention has following beneficial effect, under the inactive state, guarantees the rotating disk absolute rest by fastening screw; The velocity of rotation of rotating disk can be controlled by the pretightning force of regulating energy-stored spring; By the bolt mechanism relevant with the tooth bar position is set, accurately control the each Rotate 180 degree of rotating disk.

The specific embodiment

Below in conjunction with embodiment the footwear device that automatically turns of the present invention is described.

Embodiment 1.

As shown in Figure 1, this device is comprised of above critical piece, and is clear in order to make structural diagrams, and device appearance does not draw the pillar of side plate and bearing plate among the figure except top board and base plate.

Fig. 3 is transmission device details feature.When pin was stepped on foot push, energy-storaging spring among the tooth bar compression figure utilized the roller-way on the tooth bar to cooperate with pulley simultaneously, left behind to be stuck in alignment pin on the top board locating hole.But this moment is because gear inside is ratchet mechanism, so ratchet idle running does not drive dial rotation.In the process of tooth bar backhaul, by initial tension of spring pulling gear, drive dial rotation.The reason of taking this kind of drive is when avoiding stepping on foot push fast, and rotary speed is stepped on speed with pin and is directly proportional, and rotating speed gets rid of too soon and flies to put superincumbent slippers.And can come directly towards the length that be screwed into spring case by regulating pretension, change the pretightning force of preloading spring, thereby regulate rotary speed.

As shown in Figure 9, device is realized 180 ° of accurately process prescriptions of rotation: behind the bottom right that the tramps with one's feet end button, make the driving rack compressed energy-storage spring that moves to left by the slope; Because the gear inside that cooperates with tooth bar is ratchet mechanism, therefore, in 1 process of describing, gear idle running, rotating disk does not rotate; By the angle of roller-way and length on the design tooth bar so that: tooth bar move to left to extreme position (left end spring energy-storage), alignment pin below the rotating disk breaks away from the rotating disk locating hole in advance, when preventing that tooth bar from moving to right, alignment pin moves immediately, again blocks the rotating disk that does not have enough time to rotate; Because the energy storage of left end spring pressurized, under the driving of spring force, tooth bar moves to right; The gear that cooperates with tooth bar-ratchet mechanism drives the dial rotation coaxial with it; Locating hole by 180 degree of being separated by on the rotating disk cooperates with alignment pin, realizes the corner of each 180 degree.

The above; only be the better specific embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
