Abstract

A safety roller skate for building up body is composed of a roller track with very long length and width, a brake with lowest gravity center, a hand push cart for realizing top sliding safety, a single indoor or outdoor vehicle, a high-efficiency and wide-range body-building apparatus, and a high-safety roller skate.

Description

Safety roller skates for health-care

The technical field is as follows: shoes, roller shoes, traffic tools, fitness equipment, security equipment and furniture

Background art: the life and the health of people are not more important, the fitness of the whole people needs to be well done, and the career of the whole people needs to be more successful. However, the conventional body-building activities can only be specially carried out on special equipment and special sites outside production and life, so that the body-building activities not only occupy more physical and mental resources, but also cannot be popularized and are difficult to persist. Therefore, a novel personal vehicle which can be used by almost people for extremely saving time and money, obviously helping people to improve work efficiency, can be completely dissolved into normal production and life without storage difficulty, has low price, high efficiency, happy body building, especially balance, coordination, heart strengthening and intelligence development, and successfully promotes scientific evolution of human beings to be fantastic, is specially provided, and is a practical and safe roller shoe for national body building, which can be reproduced and simplified.

The invention content is as follows: a pair of semi-frame-shaped double-roller supports linked by a middle connecting rod are arranged on the peripheries of two sides of a rectangular hollow frame, and are fixed on the upper parts of two ends of the frame by transverse parallel concentric pin shafts and can rotate, wheel carrier connecting surfaces on two sides can turn over into movable soles, and a connecting rod is connected with each other and is fixed at the limit position by a stop block at a group of deflection positions with 90-degree difference at the outward expansion limit of the two wheel carriers. And then a rigid sole with multi-directional laces, a common shoe or a movable and openable shoe body are matched, and a new and old autonomous brake and a front wheel steering structure are manufactured according to the requirements, so that the roller skating walking shoe with various levels of performances can be formed. The rigid sole in the shoe can also be fixed on the rigid frame concentrically by a pin shaft at the slightly upper part of the centers of the front and rear ends and can rotate, the upper end clamping hole of the vertical transverse plate extending upwards at the center of the front end drives the transverse rod pipe to be outwards connected through the upper pin hole, the longitudinal axle wheel frame is fixed at the outer end of the crankshaft on the front wheel frame plate to realize steering (a ratchet wheel can be used), meanwhile, the middle part of the parallel connecting rod of the two side wheel frames is connected with a transverse vertical brake frame rod footing, the slightly upper part of the parallel connecting rod of the two side wheel frames is connected with various brake upper end connecting rods of the rear wheel frame, and the. The knee-bending brake not only reduces the gravity center, but also facilitates emergency pedaling, jumping and avoiding, and is particularly safe and practical in falling prevention and collision prevention by additionally using a fixed or foldable hand-held belt brake trolley. The cargo carrying capacity of the multifunctional backpack is far beyond that of the backpack, so that the backpack is convenient to sit and work in a chair everywhere. The combat self-defense is stronger during attack, the trolley folded into a bundle is convenient to hit the bullet of the separation knife gun, the body building self-defense is multipurpose and obviously better than the traditional mode, and the practical prospect is wide and expandable. The wheel frame is expanded into the ultra-long wide low gravity center self-steering safe roller skate, the ultra-wide non-ultra-long walking shoe is folded in the wheel frame, and the rubber pad is used for damping and preventing collision, so that the roller skate can be conveniently folded and unfolded. The front section of the shoe cover is fixed, the upper layer of the middle-rear section can be fixed, and the shoe cover can be turned upwards to be put on and taken off by strong locking by a flexible film cross-connecting torsion spring or a rear upper end sleeve turning hook matched with a vertical clamping hole which is formed by upwards folding the sole or inwards folding the peripheral frame. The two tail end loose pins of a U-shaped long plate are fixed on the front section of the shoe for sliding the rear flexible heel, and the length, the width and the width of the U-shaped long plate are self-adjusted by connecting elastic lacing to adapt to the shoes and the shoes without the shoes. Meanwhile, the brake frame rod can be inserted and stretched by a pressure spring pull wire and the like.

Description of the drawings: FIG. 1 is a side view of the highest model of the present roller shoe, FIG. 2 is a top view thereof, and other models are omitted and not shown. Fig. 3 and 4 are side elevation views of a folding cart, which is a two-column or four-column cart, at least two wheels are universal wheels, various brake pull wires of rear wheels are tied outside a top transverse sleeve, a pressure spring bolt pull wire at the outer end of each transverse folding tube penetrates through a small hole at the bottom surface and is tied on the inner side of the opposite side transverse sleeve through two opposite holes, a cloth film soft net is sleeved on the bottom side surface, and a panel is a light and hard square block and a top layer soft cushion which are adhered on the bottom surface cloth film and can be freely turned down into a chair. The frame is small and portable because the frame-shaped rod tubes are inserted and stretched. Fig. 5 is a practical illustration, fig. 6 is a partial part diagram, in which 1 rigid frame, 2 movable or fixed shoe cover, 3 universal wheel, 4 rollers, 5 wheel carriers, 6 pins, 7 sole plates, 8 connecting rods, 9 stoppers, 10 brake plates, 11 torsion springs, 12 brake frame rods, 13 extending clamping plates, 14 rubber pads, 15 clamping hooks, 16 clamping holes, 17 flexible heels, 18 laces, 19 sleeves, 20 channel steel, 21 brake handles, 22 pin holes, 23 cloth film soft nets, 24 panels, 25 wheel shafts, 26 cross-connected plates and 27U-shaped plates are arranged.

The specific implementation method comprises the following steps: the frame ring wheel carrier is formed by stamping stainless steel or high-strength steel plate.

Claims

1. A practical safety roller shoe for building up body is composed of four rollers, wheel carrier, connecting rod, frame and shoe cover, and features that each roller has four corners, the roller groups at both ends are linked by the central connecting rod between front and back ends and 90 deg. deviation, the roller groups at both ends are linked by upper transverse pin and fixed to the upper end of hollow rectangular frame, the transverse axle of front roller can be additionally equipped with a vertical axle and a transverse straight connecting rod between front and back ends of pin hole, and the rigid bottom plate of shoe cover can be linked with rigid frame ring, or the central pin at both ends can be fixed to external ring, and the flexible heel can be turned The middle part of the shoe body is provided with a transversely arranged upper frame rod which is respectively connected with the parallel connecting rods of the wheel frames at the two sides and various brake plate connecting rods of the wheel frame at the rear part to realize the automatic braking and synchronous folding and extension by the forward tilting of the leg part.
