Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of Invention] (Field of Industrial Application) This invention relates to a portable stage capable of adjusting the height of the stage in multiple stages.

(Prior Art) Conventionally, a stage that has been set up at various conventions is constructed by laying stage units whose height cannot be adjusted or arranging stage units whose height can be adjusted.

(Problems to be solved by the invention) However, the former is simply that the stages of the same height are laid on the floor, and the stage cannot flexibly respond to space planning, and the latter is a stage. The height of the stage can be selected and the stage can be constructed according to space planning.However, since the stage unit is heavy, it is difficult to manually pull out the legs while lifting the stage unit. Various mechanisms have been devised that skillfully combine the action of the stage plate, main leg, auxiliary legs with rollers, and levers, but only one auxiliary leg is attached, and the stage height is increased in multiple stages. It didn't adjust the height.

[Constitution of device]

(Means for Solving Problems) Therefore, in order to eliminate the above-mentioned drawbacks, the present invention provides two floor plates connected by a hinge, and each floor plate is provided near each corner near the folding center axis. , One end of the rod is pivotally mounted, and each side of the floorboard is provided with a telescopic leg near each corner away from the folding center axis, and the folding center axis is sandwiched between the other ends of the opposing rods. A rod is straddled, and sliders are provided on both ends of the horizontal rod so as to project, and a stage is provided in which the slider and telescopic legs are pivotally connected by crank bars; telescopic at four corners of a substantially rectangular frame. A column unit is provided in which a column is erected and a roller is attached to each end of the telescopic column, and the stage is loaded on the column unit by slidably fitting the slider to the telescopic column. Let's provide a portable stage It is what

(Embodiment) Hereinafter, one embodiment of the present invention will be described with reference to the drawings. Two floor plates (2) and (3) connected by a hinge (1) are provided, and the back surfaces of the floor plates (2) and (3) are provided. The beam members (4)
Horizontal member (8) consisting of (5) and girder members (6) and (7)
(9) is fixedly provided, and rods (6) and (7) are provided on the respective girder members (6) and (7) near the corners of the horizontal members (8) and (9) near the folding center axes of the floor plates (2) and (3). 10) The floor plate (2) is provided by pivotally connecting one end of (11) so as to be rotatable in the column direction.
Near each corner away from the folding center axis of (3),
Telescopic legs (12) (13) are pivotally mounted, and a horizontal rod (14) is laid across the other ends of the rods (10) (11) facing each other with a folding center axis interposed therebetween. ) Has a cross section at both ends
C-shaped sliders (15) (16) are provided so as to project, and the sliders (15) (16) and the telescopic legs (12) (13) are pivotally connected by crank bars (17) (18). The stage (A) is formed, and the telescopic columns (20) are attached to the four corners of the substantially rectangular frame member (19).
(21) is erected, and a column unit (B) is provided which is provided with rollers (22) and (23) at the ends of the telescopic columns (20) and (21), respectively, and the sliders (15) and (16) are provided. It is a portable stage characterized in that the stage (A) is loaded on the column unit (B) by slidably fitting it to the telescopic columns (20) (21).

In addition, the caster unit (24) is provided between the telescopic columns (20) and (21) standing upright at the four corners of the substantially square frame member (19), and the handle (25) is operated on the caster unit (24). Lifting casters (26) and floor boards (2)
A cylinder (27) connected to the back surface of (3) may be provided.

(Operation) In this usage, as shown in the figure, when the stage (A) is first folded and loaded on the column unit (B), the floor plates (2) and (3) follow the folding center axis on which the hinge (1) acts. It is folded and set up with each surface facing each other. The cylinder (27) is mounted on the rear surface of the floor plates (2) and (3) and the caster unit (24), and the cylinder (27) at this time assists in maintaining the standing state of the stage (A). There is a role of. The horizontal rod (14) is a slider (15)
The pair of slides between the (16) and the side surfaces of the telescopic columns (20) (21) horizontally descends and abuts the upper surface of the frame member (19), and the floor plates (2) and (3) are already described. The floor plate (2) (which is held in a hollow state by the rods (10) and (11) and the crank bars (7) and (8) in a folded state as shown in FIG. Prevent the development of 3).

To unfold the folded floorboards (2) and (3), first of all, from the above state, depending on the height to be set, the girder member (6).
Telescopic legs (12) for pivotal connection while hanging from (7)
Pull out the legs built in (13) to the desired position and secure them with the stoppers (28) (29). Telescopic columns (20)
Similarly for (21), pull out the built-in pillar to the desired position,
Secure with stoppers (30) (31). Next, when the floor plates (2) and (3) are opened while resisting the action of the cylinder (27), the rollers (22) (23) provided at the tips of the columns incorporated in the telescopic columns (20) (21). ), The floor board (2)
The back surface of (3) contacts. When the floor plates (2) and (3) are further opened while receiving the sliding movement, the horizontal rod (14) rises away from the abutting frame member (19) and the girder member (6).
The fulcrum of rods (10) and (11) pivotally connected to (7) is raised. Crank bars (17) (18) are floor plates (2) (3)
The folded telescopic legs (12) and (13) are opened with the opening of. The stage (A) where the two floorboards (2) and (3) are horizontal after the opening is completed is the telescopic legs (12) (13).
And it is supported by the telescopic columns (20) (21) and is stabilized on the floor at a predetermined height. Lifting casters (26)
Can be moved up and down by operating the handle (24), so when using the stage (A) to expand it, lift the lift casters (26) away from the floor surface and fold the stage (A). To move the column unit (B), push the lift caster (26) downwards to lift the column unit (B) from the floor surface, and lift the column unit (B) carrying the stage (A) by the lift caster (26). Can move horizontally.

[Effect of device]

According to this invention, it is possible to provide a multi-stage stage that can be widely used for space planning, and even though it is a sturdy and heavy-duty large stage, the telescopic legs and telescopic columns can be pulled out in multiple stages with extremely simple operations. , The height of the stage can be set freely, and it is highly reliable and easy to use.
