1. Field of the Invention
The present invention is related to an angular appearence ofRefering firstly Referring first to FIG. FIGS. 1 and 2 of the drawings, the present invention is comprised of: a plurality of skid-proof pads 1, a plurality of skid-proof pad seats 2, and pairs of side plates 3, wherein, each. Each skid-proof pad 1 is integrally assembled on a skid-proof pad seat 2, while the side plates 3 are provided for mounting and positioning and adjusting of angular positions of the skid-proof pad seats 2. Each skid-proof pad 1 is made of soft material providing skid-proof effect, thei . The function thereof is to obtain the skid-proof effect by friction force induced by contact thereof with the ground, there. There is an undulated plate 10 on the surface thereof, the bottom thereof is provided with a plurality of engaging members 11 protruding downwardly downward, and the engaging members 11 each is are comprised of an extension portion 110 and an enlarged end 111.
Each skid-proof pad seat 2 is provided thereon with a groove 20 for receiving a skid-proof pad 1, the. The groove 20 is provided with a plurality of engaging slots 21 for engagement of the engaging members 11 of the skid-proof pad 1, such as is shown in FIG. 2, the. Each of the engaging slots 21 each is provided with two opposite stop pieces 211 which have a gap therebetween, when. When the enlarged end 111 at the lower end of the skid-proof pad 1 is inserted into the gap between the stop pieces 211, the skid-proof pad 1 can be engaged with the skid-proof pad seat 2; and the. The skid-proof pad seat 2 is provided on either side thereof mutually oppositely with a protruding axle 25.
The Each of the side plates 3 are provided thereon each with an axle hole 30 which is provided on the top thereof with a reduced engaging neck 31, the. The protruding axles 25 of the skid-proof pad seat 2 can be placed in the axle holes 30 and are not to be moved out secured therein by locking of the reduced engaging necks 31 (as shown in FIG. 3);. After putting the protruding axles 25 in the axle holes 30, the skid-proof pad seat 2 can be adjusted to any angular position between the side plates 3.
Referring to FIG. FIGS. 4 and 5 which show an embodiment of the present invention mounted on a baby stroller walker, wherein the side plates 3 are provided integrally on the lower portion of the chassis 4.
The skid-proof pad seat 2 is capable of random changing of its angular position by means of the protruding axles 25 and the axle holes 30, so that the skid-proof pad seat 2 is capable of maintaining being maintained in a parallel position to the ground surface normally. Referring to FIG. 6, a plurality of bracing sheets 41 and elastic sheets 42 are provided in the chassis 4, while the skid-proof pad seat 2 is also provided with a plurality of internal sheets 27, hence the skid-proof pad seat 2 can be maintained constantly in a parallel position to the ground normally by means of the bracing sheets 41 and elastic sheets 42; on the contrary, when the skid-proof pad seat 2 is tilted by virtue of an external force, the elastic sheets 42 will be bent and afterwards will be recovered recover when the force is removed.
Referring to FIG. 7, when a roller 49 rushes out moves off of a ground surface 5 to be suspended in the air in a stairway 6, the chassis 4 is tilted, however, the skid-proof pad seat 2 automatically adjusts its angular position to parellel be parallel to the ground surface 5 by means of the protruding axles 25 and the axle holes 30, the. The contact area of the skid-proof pad 1 and the ground surface 5 is a whole plane which has better friction capability than a the linear contact area of the prior art, so that the baby stroller walker can be prevented from further dropping.
In conclusion, the angular auto-adjustive auto-adjusting skid-proof pad system of the present invention on a baby stroller providing walker provides the function of skid-proof and braking when any roller of the baby stroller rushes walker moves out of a ground surface to be suspended in the air in a stair way, and especially providing provides a friction contact plane capable of automatical automatically adjusting angular positions of the skid-proof pads to be constantly parallel to the ground surface,. The system can effectively prevent the baby stroller walker from the danger of falling down stairs, this mechanism with such function has never existed in the markets or been published, thus the present invention is provided with improveness and practicability, therefore,
What I claim as new and desire to be secured by Letters Patent of the United States are:.
