Abstract
Load such as a large screen TV set is supported with improved stability without losing mobility, by providing resilient members such as compression springs between the supporting fiat base whereon the TV set is mounted and plural load supporting bodies which are rollers held vertically movable to some extent. When a strong outside force is applied, for instance, the TV set is strongly pushed from its back, the front rollers are retracted by compression of the spring, thereby the front bottom edge of the console touches the floor and resisting force or reaction force against the fall down of the TV set much increases.
Claims10
A load supporting apparatus for supporting an audiovisual assembly comprising:
- a supporting base,
- plural load supporting bodies mounted to said supporting base so that said supporting base is vertically movable with respect to the support bodies, and
- resilient members provided between each of said load supporting bodies and said supporting base, which permit the supporting base to move vertically with respect to the supporting bodies against a resilient force of the resilient members and, when a force which acts on said supporting base exceeds a predetermined amount, permit an edge of said supporting base to come into contact with a surface on which the load supporting apparatus is disposed, thereby increasing an angle formed between a vertical line through a center of gravity of said apparatus and an oblique straight line connecting the center of gravity of the audiovisual assembly and a forward most point of contact of said load supporting apparatus.
A load supporting apparatus for supporting an audiovisual assembly comprising:
- a supporting base,
- guide pins fixed vertically on said supporting base,
- plural load supporting bodies coupled to said guide pins so that said supporting base and said guide pins mounted thereto are vertically movable relative to the load supporting bodies, and
- tension springs whose ends are engaged to engaging means on said supporting base and to engaging means on said load supporting bodies.
A load supporting apparatus for supporting an audiovisual assembly comprising:
- a supporting base,
- roller supporting shafts fixed horizontally to supporting parts provided on said supporting base,
- roller supporting members including roller shafts rotatably mounted to said roller supporting shafts, rollers borne by said roller shafts, and resilient means provided between said roller supporting members and said supporting parts in a manner to give a predetermined downward force to said rollers in relation to said supporting base.
A load supporting apparatus for supporting an audiovisual assembly comprising:
- a supporting base,
- at least two cylinders provided in said supporting base, each cylinder being divided into two parts by a slidable piston and each divided part containing fluid inside, said divided parts being connected through respective ports in a manner that an upper divided part of one cylinder being connected to a lower divided part of the other cylinder and vice versa, said pistons being linked to load supporting bodies, and being urged by resilient members to keep each of said at least two pistons at substantially an intermediate in said respective cylinder thereby holding said supporting base horizontal in a normal state wherein no external falling-down force is applied to said audiovisual assembly.
