Description

[Technical field]

[0001] The present invention relates to a wall-mounted stage that is stored upright in a storage compartment recessed into a wall. [Background technology]

[0002] The applicant of the present application has previously developed a wall-mounted stage which is stored in an upright state in a storage compartment recessed into a wall, with fixed legs fixed upright on the floor of the storage compartment recessed into the wall, and the base end of a stage body which can be tilted up and down to a horizontal state and an upright state being pivotally attached to the upper part of the fixed legs, and the bottom plate of the stage body which is flush with the wall when the stage body is upright is formed with at least a divided tip and serves as a support leg which protrudes at a right angle when the stage body is horizontal, and the support leg is rotatably provided so as to be flush with the bottom plate when the stage body is upright, and a damper is installed between the support leg and an appropriate position on the underside of the floor plate, and the support leg can be extended and retracted by extending and retracting the rod of the damper, so that when the support leg of the stage body in the stored state is flush with the bottom plate and the damper rod is in a maximum retracted state, and when the support leg of the stage body in the horizontal state is protruding at a right angle to the bottom plate and the damper rod is in a maximum extended state (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2018-99249 A Summary of the Invention [Problem to be solved by the invention]

[0004] With the above-mentioned conventional technology, while it is certainly possible to ensure the uniformity of the wall surface in the stored state, there was a problem that needed to be solved: if a strong impact was applied to the support legs, such as a child sitting at the front of the stage and dangling their legs that do not reach the floor, hitting them with force, the rods in the fully extended state would retract, causing the support legs to tip backwards and tilt the stage, posing a slight risk of accidents such as people or objects on the stage toppling over or falling off the stage. [Means for solving the problem]

[0005] In view of the problem based on the above-mentioned conventional technology in which the risk of the support legs falling backwards when a strong impact is applied to them cannot be eliminated, the present invention provides a stage body whose base end is pivotally attached to the floor side and a stage body with a stopper between the support legs that can maintain the right-angle position of the support legs in relation to the horizontal stage body, and the stopper stands up when the stage body is in a horizontal position so that its tip can abut against the underside of the support leg, and when the stage body is in an upright position it can be lowered and stored between the stage body and the support legs, thereby not only ensuring the uniformity of the wall surface in the stored state, but also preventing the support legs from falling backwards when in use, thereby solving the above-mentioned problem. Effect of the Invention

[0006] In short, the present invention provides a method for making a stage stand that includes fixing legs upright on the floor of a storage shed recessed into a wall, pivoting a base end of a stage body that can be raised and lowered to a horizontal state and an upright state to an upper portion of the fixing legs, and a bottom plate of the stage body that is flush with the wall when the stage body is upright, at least a tip portion of which is formed so as to be separable, and that can protrude at a right angle as a support leg when the stage body is horizontal, and that is rotatably provided so as to be flush with the bottom plate when the stage body is upright, and that the stage body in a horizontal state is provided between the stage body and the support leg. Stoppers are provided that can maintain the support legs in a perpendicular position relative to the body, and the stoppers stand up when the stage body is horizontal, with their tips able to abut against the undersides of the support legs, and can be lowered when the stage body is upright and stored between the stage body and the support legs.When stored, the bottom plate including the support legs is flush, ensuring uniformity with the wall, and when in use, even if an impact is applied to the support legs, the stoppers prevent them from falling toward the back, reliably preventing accidents such as falls caused by the stage tilting.

[0007] A base plate is placed on the back side of the stage body, the base plate is parallel to the width direction of the stage body and is inclined from the tip side to the base side and from the front side to the back side of the stage body, and the stopper is pivotally attached to the tip side surface of the stage body of the base plate so that it can be raised and lowered about an axis perpendicular to the longitudinal direction of the base plate. Therefore, when the stage body is in a vertical position, the stopper is provided on the upward-facing surface of the base plate, so that the base plate can automatically be placed in a lowered state, and when the stage body is in a horizontal position, the stopper is provided on the downward-facing surface of the base plate, so that the base plate can automatically be placed in an upright state. Therefore, the stopper can be automatically raised and lowered by raising and lowering the stage body.

[0008] Since the base end of the stopper is capable of abutting against the base plate in an upright state, the stopper can be maintained in an upright position during use, thereby providing significant practical benefits such as ensuring that the support legs are kept locked when in use.

[0010] An embodiment of the present invention will now be described with reference to the drawings. The tiltable stage of the present invention basically comprises a base end pivotally attached to the floor surface f of the stage installation room R of a stage main body 1 which can be tilted and lowered in a horizontal and upright state, and a bottom plate 2 which is flush with the wall W of the stage installation room R when in an upright state, arranged on the back side of the stage main body 1, at least the tip portion of the bottom plate 2 is formed so as to be separable into support legs 3 which protrude at a right angle when the stage main body 1 is in a horizontal state and which are parallel to the stage main body 1 when in an upright state, and the support legs 3 are formed in the shape of panels whose width is approximately the same as the stage main body 1 and are rotatably arranged so as to fit flush with the bottom plate 2 when the stage main body 1 is in an upright state, and stoppers 4 which are capable of maintaining the right-angle position of the support legs 3 with respect to the stage main body 1 in a horizontal state are arranged between the stage main body 1 and the support legs 3, and the stoppers 4 stand up when the stage main body 1 is in a horizontal state and their tips abut the back surfaces of the support legs 3, and when the stage main body 1 is in an upright state they lie down and are stored between the stage main body 1 and the support legs 3. The specific details will be explained below.

[0011] FIG. 1 is a front view showing the tiltable stage of the present invention stored against a wall, FIG. 2 is a cross-sectional view taken along line AA in FIG. 1, and FIG. 3 is a cross-sectional view of the stage in a horizontal position, which is set up so that it can be stored in an upright position in a hangar H recessed into the wall W of the stage installation room R.

[0012] The stage body 1 is formed in a flat box shape having a floor board 5 arranged horizontally in a horizontal state, a pair of elongated, strip-shaped side boards 6, 6a arranged on the left and right edges of the floor board 5, and a elongated, strip-shaped riser board 7 arranged on the left and right edges of the floor board 5 and spanning between the tips of the side boards 6, 6a.

[0013] The stage main body 1 has multiple joists 8, 8a... arranged in parallel across the width on the back side of the floorboards 5, and multiple fixed legs 9, 9a... fixed in parallel and in the horizontal (left-right) direction on the floor surface f of the hangar H at specified intervals. The base ends of the joists 8, 8a... are pivotally connected to the fixed legs 9, 9a..., allowing the stage main body 1 to be raised or lowered.

[0014] The bottom plate 2 is arranged parallel to the floor plate 5 on the back side of the stage body 1 and is flush with the wall W when the stage body 1 is upright. The bottom plate 2 is composed of a support leg 3 at the tip and a bottom plate body 10 that occupies the rest of the plate, and the support leg 3 is rotatably arranged so that it fits flush with the bottom plate body 10 (is arranged on the same plane) and becomes the floor plate 5 when the stage body 1 is upright.

[0015] The underside of the base end of the support leg 3 is pivotally attached to the underside of the stage body 1 by a hinge section provided at an appropriate location, and a rod 11 is attached to a damper 12 which can be expanded and contracted between a plurality of brackets provided on the underside of the support leg 3 and the floor board 5 at appropriate locations, making it possible to maintain the vertical position of the support leg 3 at all times when the stage body 1 is raised or lowered, and ground contact sections 13 whose protruding length can be adjusted are provided at multiple locations on the underside of the tip of the support leg 3.

[0016] The stoppers 4 are mounted on a base plate 14 that is erected between adjacent joists 8, 8a.... The base plate 14 is inclined from the tip end of the stage body 1 towards the base end and from the front side to the back side, and the stoppers 4 are arranged on the surface of the base plate 14 near the tip end of the stage body 1 so as to be able to rise and fall freely around an axis perpendicular to the longitudinal direction of the base plate 14.

[0017] As shown in Figures 4(a) and 4(b), the stopper 4 is attached via hinges 16 to the upper surface of a mounting block 15 fixed to a base plate 14, and specifically has an undulating plate 17 and a stopper body 18 provided on the side of the oscillating plate 17 in the falling direction, and the stopper body 18 protrudes from the tip of the oscillating plate 17.

[0018] The stopper body 18 is composed of a fixing nut 19 attached to the embossing plate 17, a bolt body 20 screwed into the fixing nut 19, and an adjustment nut 21 screwed into the middle part of the bolt body 20. After adjusting the protruding length of the bolt body 20 relative to the fixing nut 19, the adjustment nut 21 is tightened to fix the bolt body 20, and an abutment block 22 for the stopper 4 is provided on the back surface of the support leg 3.

[0019] It is preferable that the undulating plate 17 is formed so that the base end abuts against the substrate 14 when it is perpendicular to the substrate 14 . Specifically, as shown in FIG. 4(b), the length of projection of the base end portion of the undulating plate 17 from the rotation center 16a of the hinge 16 is the same as the height of the rotation center 16a of the hinge 16 relative to the base plate 14.

[0020] Then, as shown in Figure 3, to use the stage body 1 in the stored state as a stage, the stage body 1, which is in a vertical state, is rotated down so that when the stage body 1 becomes horizontal, the contact portions 13 of the support legs 3 which protrude at right angles to the stage body 1 come into contact with the floor surface f, and the tips of the upright stoppers 4 come into contact with the abutment blocks 22 of the support legs 3, so that the floor boards 5 are positioned horizontally on the upper layer and the support legs 3 do not fall inward.

[0021] In other words, since the stopper 4 is provided on the surface of the base plate 14 that faces upward when the stage body 1 is in a vertical position, the stopper 4 automatically falls to a lowered position, and since the stopper 4 is provided on the surface of the base plate 14 that faces downward when the stage body 1 is in a horizontal position, the stopper 4 automatically falls to an upright position.

[0022] Furthermore, to store the stage body 1 in an upright state in the storage shed H, the stage 1 is raised and rotated in the reverse order, the raised stopper 4 falls down, the support legs 3 are returned to their original position so as to be parallel to the stage body 1, and the support legs 3 and the bottom plate body 10 become flush with each other to form the bottom plate 2.
