Abstract

The utility model relates to a movable bleacher structure, comprising a plurality of layers of telescopic platforms (1) and a plurality of folding seats (2) arranged on each platform (1). The utility model is characterized in that the front part and the rear part of at least one layer on the platforms (1) are provided with at least two rows of seats (2); a plurality of seats (2) on the same platform (1) can have the equal height or can be heightened step by step from the front part to the rear part. The seats are greatly increased under the condition of few increasing or less increasing height of the bleacher, which can effectively solve the difficult problem that the movable bleacher can be used in the occasion of lower indoor clear height so as to accommodate more audiences and can more effectively make use of space.

Description

A kind of movable stand structure

The utility model relates to a kind of movable stand structure.

Movable stand is a kind of facility that generally is used for public places such as sports palace, assembly hall, include the multilayer platform, folding seat is arranged on each platform, during use, each platform is drawn back layer by layer and the folding seat on it is opened, during collection, that the seat on each platform is folding and each platform is punctured into the box duplexer layer by layer.Existing movable stand generally only is equipped with row's seat, also require to hold the attendance more for a long time when the site space that movable stand is installed is big, certainly will require the number of plies of grandstand to increase, thereby the overall height of grandstand will also be increased simultaneously, and the interior net storey height in general house is subjected to floor height and overhead illumination, the influence of ornaments such as sound equipment, differ and satisfy the overall height of grandstand surely, so just must reduce the grandstand height of each layer, but grandstand individual layer height is by grandstand component thickness and the decision of seat fold thicknesses, because intensity, structural requirement, accomplish quite difficulty of this point, so the grandstand structure of the single seat of existing one deck can not be taken into account the contradiction between the overall height of the seating capacity of grandstand and grandstand, be not suitable for lower and the situation that the positional number requirement is more of interior net storey height.

The purpose of this utility model just is to provide at above-mentioned present situation a kind of lower and movable stand structure of the occasion that the positional number requirement is more of interior net storey height that is suitable for.

Design scheme of the present utility model is: include the scalable platform of multilayer, each platform is provided with seat, is provided with at least two row's seats before and after being at least on one deck platform with existing movable stand difference part.It can be contour arranging seat with the front and back on one deck platform more, also can be slightly to raise step by step from front to back.

Compared with prior art, the utility model can do not increase or the situation of less increase grandstand height under roll up the seat, solved effectively in the lower occasion of interior net storey height and used movable stand to hold more spectators' a difficult problem, also more effectively utilized the space.

Description of drawings:

Fig. 1 is the view of drawing back of the utility model embodiment 1.

Fig. 2 is the folded state schematic diagram of the utility model embodiment 1.

Fig. 3 is the view of drawing back of the utility model embodiment 2.

Fig. 4 is the folded state schematic diagram of the utility model embodiment 2.

Embodiment is described in further detail the utility model below in conjunction with accompanying drawing:

As shown in Figure 1, 2, the embodiment for the contour seat of one deck platform two rows suitably adds the width of large platform (1), and two row's contour seats (2) before and after being provided with on every layer of platform (1).

Shown in Fig. 3,4, for one deck platform two is arranged the not embodiment of contour seat, the width that suitably adds large platform (1), and two row's not contour seats (2) before and after on every layer of platform (1), being provided with, back parallelism is front-seat high half grade, though the thickness of every layer of platform increases to some extent like this, be less than the height of original two-layer platform.

Certain every layer of platform (1) also can be provided with the seat (2) more than two rows, the seat of each layer platform (2) row number also can be different, but platform (1) width generally need the corresponding increase along with the increase of rows of seats number, many in this way rows are the scheme of contour seat not, then the thickness of every layer of platform (1) also need be decided on the environment of concrete enforcement along with increase.

Claims

1. a movable stand structure includes the scalable platform of multilayer (1), and each platform (1) is provided with seat (2), it is characterized in that having at least on the described platform (1) one deck front and back to be provided with at least two row's seats (2).

2. movable stand structure as claimed in claim 1 is characterized in that described is contour with the many rows seat (2) on one deck platform (1).

3. movable stand structure as claimed in claim 1 is characterized in that describedly increasing step by step from front to back with the many rows seat (2) on one deck platform (1).
