Layable seat

Abstract

A layable seat includes front and rear paired supporting legs which are layably raised on a floor at two positions separated from each other in a back-and-forth direction, a seat member pivotably connected to the front paired legs, paired link levers each of which has one end pivotably connected to the corresponding one pivotal center of the seat member and the other end pivotably connected to the corresponding rear leg. The seat member is elastically held at its half-folded position by torsion coil springs, and has paired engaging pins which project sideward therefrom and engage the lower edges of the link levers to hold the seat member at its horizontal position against a user's weight.

Description

BACKGROUND OF THE INVENTION1. Field of the InventionThe present invention relates to a seat and, more particularly, to a layable seat which is entirely pivotal between a horizontally laid non-use position where the seat is laid horizontally along a floor surface, and a raised use position where the seat is raised from the floor.2. Description of the Related ArtThe layable seat described above is known from, e.g., Published Unexamined Japanese Patent Application No. 62-101211. Such a seat is set on the upper surface of each of a plurality of nestable decks, which are movably installed on the floor surface of, e.g., a gymnasium, a community center, or a multi-purpose hall, and have sequentially different heights. And, these seats are used to temporarily set seats or increase the number of seats.Each of the plurality of decks has a plurality of wheels at its lower end portion so that the deck is movable on the floor surface of the building as described above. The plurality of decks are...

AI Technical Summary

Benefits of technology

The present invention has been derived from the above situation, and its object is to provide a layable seat which can hold a seat member at a half-folded position between a horizontal use position and a vertically folded position before a user sits down while the layable seat is set at a raised use position, so that the user can move the seat member to the horizontal use position with his or her buttocks without using his or her hand, and which can make the entire portion of the seat member reach at a horizontally laid non-use position of the layable seat at once when the layable seat is pivoted from the raised use position to the horizontally laid non-use position, thereby preventing damage to a part of the seat member and to a portion of a floor surface corresponding to the part of the seat member, and soiling of the clothes of the user which touch the seat member.

When the supporting leg means is pivoted from the raised position to the horizontally laid position in order to pivot the layable seat from a raised use position to a horizontally laid non-use position, the forcible moving means forcibly moves the seat member to the folded position against the urging force of the urging means in response to the pivotal movement of the supporting leg means from the raised position to the horizontally laid position. Hence, the entire portion of the seat member can reach the horizontally laid position at once, damage to a part of the seat member and to a portion of a floor surface corresponding to the part of the seat member can be prevented, and soiling of the clothes of the user which touch the seat member can be prevented.

By preparing a plurality of nestable movable decks of this type having sequentially different heights, mounting a plurality of layable seats according to the present invention side by side on each of the movable decks, extending the plurality of movable decks in a telescopic manner, and locating the supporting leg means of the plurality of layable seats on the upper surfaces of the extended movable decks at the raised position, a large number of seats can be additionally, temporarily installed within a short period of time. When these seats are not used, the supporting leg means of the plurality of layable seats on the upper surfaces of the movable decks are pivoted to the horizontally laid position, and thereafter the plurality of movable decks are contracted to be nested, thereby minimizing the space required for housing the plurality of movable decks.

The supporting leg means, the seat member, and the forcible moving means having the above arrangements are compact in size and simple in structure.

The urging means having such an arrangement is simple in its structure and makes the entire structure of the layable seat compact.

Problems solved by technology

For this reason, every time the front end of the seat member abuts against the upper surface of the corresponding deck, comparatively large noise is produced.

The front end of the seat member, and a portion of the upper surface against and on which the front end of the seat member constantly abuts and slides can be easily damaged.

Furthermore, since the front end of the seat member is soiled by this slidable contact, it soils the clothing of the user who contacts it.
