Definitions

  • the present invention relates to a movable spectator's stand with an auxiliary spectator's stage, and more particularly, to a movable spectator's stand with an auxiliary spectator's stage, which accommodates spectators having a capacity much more than the maximum occupant load given by a limited installation space, defines a smooth and clean external appearance when the movable spectator's stand is retracted, and prevents safety accidents generated due to the approach of children thereto.
  • Korean Utility Model Registration No. 20-0284971 and Korean Patent Laid-open Publication No. 10-2004-0084070 disclose conventional movable spectator's stands.
  • the above conventional movable spectator's stands are configured such that multistage spectator's stages including a plurality of foldable chairs installed thereon are protracted and retracted, and more effectively use a space, such as a gymnasium, an assembly hall, an indoor chamber, or an exhibition center, thus being increasingly demanded.
  • the maximum height of each of the above movable spectator's stands is limited based on the safety of spectators, the viewing angle of spectators seated on the uppermost spectator's stage, and the height of the installation space, and the length between front and rear ends of each of the spectator's stages is limited in order to obtain a sufficient space when each of the above movable spectator's stands is folded.
  • the above movable spectator's stands cannot accommodate spectators having a large capacity, and thus, when the spectator capacity exceeds the occupant load, handy chairs must be placed in front of the protruded spectator's stages in order to accommodate all of the spectators, thereby requiring an additional space for storing the handy chairs as well as incurring costs for purchasing the handy chairs. Further, whenever the handy chairs are used, it takes a great deal of manpower and time to place and remove the handy chairs.
  • the multistage spectator's stages and the foldable chairs installed on the multistage spectator's stages are exposed to the outside, thereby detracting from the external appearance of the movable spectator's stand. Further, when the movable spectator's stand is not in use, people easily collide therewith, or children, who have little attentiveness, play on the movable spectator's stand as a playing tool, thereby frequently encountering safety accidents when going up and down the exposed multistage spectator's stages. Accordingly, methods for preventing the above problems are required without delay.
  • the present invention has been made in view of the above problems, and it is an object of the present invention to provide a movable spectator's stand with an auxiliary spectator's stage, which accommodates spectators having a large capacity while not interfering with the height and the length thereof given by a limited installation space, and covers multistage spectator's stages and foldable chairs installed thereon and serves as a wall member, when the movable spectator's stand is retracted.
  • the above and other objects can be accomplished by the provision of a movable spectator's stand with an auxiliary spectator's stage, wherein the auxiliary spectator's stage is foldably connected to the front part of the lowermost spectator's stage of multistage spectator's stages.
  • the auxiliary spectator's stage has dimensions sufficient to cover the front surface of the retracted movable spectator's stand when the auxiliary spectator's stage is folded.
  • the auxiliary spectator's stage may include foldable chairs installed thereon.
  • the auxiliary spectator's stage may include handy chairs installed thereon.
  • the auxiliary spectator's stage B of the movable spectator's stand A of the present invention When the auxiliary spectator's stage B of the movable spectator's stand A of the present invention is not in use, the auxiliary spectator's stage B is folded to the front part of the lowermost spectator's stage in a state in which the auxiliary spectator's stage B is separated from the lowermost spectator's stage by the minimum interval. Accordingly, the movable spectator's stand A with the auxiliary spectator's stage B of the present invention accommodates spectators having a large capacity in proportion to the dimensions of the auxiliary spectator's stage B while not interfering with the height and the length thereof given by a limited installation space, and eliminates inconvenience due to the use of separate handy chairs for accommodating excess spectators.
  • the auxiliary spectator's stage B When the auxiliary spectator's stage B is folded after the movable spectator's stand A of the present invention is retracted, the auxiliary spectator's stage B covers the multistage spectator's stages 2 a and 2 b and the foldable chairs 4 a installed thereon to define a smooth and fine external appearance, and serves as a wall member perpendicular to the surface of the earth to prevent safety accidents generated due to the approach of children thereto.
  • the movable spectator's stand A of the present invention is configured such that the auxiliary spectator's stage B is foldably connected to the front part of the lowermost spectator's stage 2 a , thereby being simply applied to structures of conventional movable spectator's stands.
