Technical Field

The invention relates to the field of furniture, in particular to a stair structure.

Background

Furniture is an essential appliance for human beings to maintain normal life, engage in production practice and develop social activities. Furniture is continuously developed and innovated along with the foot step of the times, and is one of indispensable parts of family life as the doors are various, the materials are different, the varieties are complete, and the purposes are different nowadays.

The furniture is composed of four factors of materials, structures, appearance forms and functions, wherein the functions are the leading factors and the power for promoting the development of the furniture, and the structures are the main lines and the foundation for realizing the functions. These four factors are interrelated and restrictive. Furniture also has material and appearance form factors, as it is designed and manufactured to meet certain material needs and use purposes.

At present, the space occupied by the stair structure of the existing furniture is large, the space used actually is limited, the area of the tread is small, certain potential safety hazards exist, and the panic psychology of a user is easy to cause.

Disclosure of Invention

The invention provides a stair structure, which occupies a smaller space, can build a larger using space, has a large area of a tread surface, is safer to go up and down stairs, can eliminate the panic psychology of a user, and is more humanized.

The invention relates to a stair structure which comprises pedal layers and a support, wherein the pedal layers are installed on the support, the pedal layers comprise a topmost pedal, a middle pedal layer and a bottommost pedal from top to bottom, two adjacent pedals of the middle pedal layer are projected from top to bottom, when the area of the lower pedal cannot be covered by the upper pedal, one end of the outer pedal surface of the pedal of the middle pedal layer is large in area, the other end of the outer pedal surface of the pedal of the middle pedal layer is small in area, the pedal surfaces of the two adjacent pedals are staggered in size, and the upper pedal is installed at the position, close to the inner side, of the support relative to the lower pedal.

Preferably, the outer edges of the pedals of the middle pedal layer are inclined edges, and the inclined directions of the outer edges of the inclined edges of two adjacent pedals of the middle pedal layer are opposite.

Preferably, the outer edge of the topmost step is a straight edge.

Preferably, the outer edge of the topmost pedal is a bevel edge, and one end of the treading surface is large in area, the other end of the treading surface is small in area, and the size of the treading surface is staggered with that of the lower adjacent pedal.

Preferably, the outer edge of the lowermost step is a straight edge.

Preferably, the outer edge of the bottommost pedal is a bevel edge, one end of the treading surface is large in area, the other end of the treading surface is small in area, and the size of the treading surface is staggered with that of the upper adjacent pedal.

Preferably, the pedals of the topmost pedal, the bottommost pedal and the middle pedal layer are all provided with non-slip mats.

For a long time, the stair has two structures, one is a straight-up stair and a straight-down stair, and the other is a spiral stair. The stair need not only consider the security of tread face, also consider the problem of occupation space. Whether the stairs are straight up and straight down or the stairs, only one of the problems of treading safety and occupied space can be considered in a limited way, and the other problem is sacrificed, namely, if the stairs with large treading surfaces and high safety are treaded, the occupied space is large; if the occupied space is small, the tread surface is small and the safety is low. The stair structure comprises pedal layers and a support, wherein the pedal layers are installed on the support, the pedal layers comprise a topmost pedal, a middle pedal layer and a bottommost pedal from top to bottom, two adjacent pedals of the middle pedal layer are projected from top to bottom, when the area of the pedal on the upper side cannot cover the pedal on the lower side is seen, the area of one end of the pedal on the outer side of the pedal of the middle pedal layer is large, the area of the other end of the pedal is small, the sizes of the pedal surfaces of the two adjacent pedals are staggered, and the pedal on the upper side is installed at the position, close to the inner side, of the support relative to the pedal on the lower. The size of the pedal surface determines the problem of treading safety, the larger the treading area is, the higher the safety of people is, and on the contrary, the lower the safety of people is. The invention breaks the prejudice of the prior art, a user treads one end of the pedal with larger area by feet, the area of the pedal on the upper layer is smaller relative to the area of the other end, and the reserved space is larger, so that the pedal has a larger tread surface, meanwhile, the knee or the shank can be prevented from colliding with the stairs on the upper layer, then the other foot treads one end of the pedal with larger area on the upper layer, and similarly, the pedal also has a larger tread surface, and meanwhile, the knee or the shank can be prevented from colliding with the stairs on the upper layer. Meanwhile, as the tread surfaces of two adjacent pedals of the middle pedal layer are staggered in size, the stair structure can save 1/3-1/2 volume compared with the prior common stair structure under the condition of the same number of pedals and the tread surfaces with the same maximum width. Compared with the prior art, the stair structure occupies a smaller space, can build a larger using space, has a large area of the tread surface, is safer to go up and down stairs, can eliminate the panic psychology of a user, and is more humanized.
