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] Previously, the applicant of the present application developed a wall-mounted stage that is stored upright in a storage compartment recessed into the wall. The stage has fixed legs fixed upright on the floor of the storage compartment, and the base end of a stage body that can be raised and lowered to a horizontal and upright position is pivotally attached to the top of the fixed legs. The bottom plate of the stage body, which is flush with the wall when the stage body is upright, has at least its tip divided and forms support legs that protrude at right angles when the stage body is horizontal. The support legs are rotatable so that they fit flush with the bottom plate when the stage body is upright. Dampers are installed between the support legs and the underside of the floor board in appropriate positions, and the support legs can be extended and retracted by extending and retracting the damper rod. When the stage body is stored, the support legs are flush with the bottom plate, with the damper rod in its most retracted position, and when the stage body is horizontal, the support legs protrude at right angles to the bottom plate, with the damper rod in its most extended position (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2018-99249 Summary of the Invention [Problem to be solved by the invention]

[0004] However, with the above-mentioned conventional technology, depending on the height from the floor to the top of the stage, it may be impossible for small children or the elderly to get onto the stage from the edge or side of the stage, so it is necessary to install steps or the like in advance in designated positions to assist them in getting onto the stage. However, this creates a lack of unity with the stage, which looks unsightly, and also requires additional work to install and remove, as well as storage space, and there are other issues that need to be resolved. [Means for solving the problem]

[0005] In view of the problem based on the above-mentioned prior art that requires the separate installation and removal of a step stool as an aid for getting onto the stage, this invention solves the above-mentioned problem by providing a stage that has a stage body and steps arranged along at least one of the three sides and tip of the stage body, the base of the stage is pivotally attached to the floor of the stage installation room so that it can be raised and lowered to a horizontal position and an upright position, and in the upright position can be stored in a hangar recessed into the wall of the stage installation room, the bottom plate of the stage is flush with the wall when in the upright position and at least the tip is formed so that it can be separated, so that it can protrude at a right angle as a support leg when the stage is horizontal and is rotatable so that it fits flush as the bottom plate when in the upright position, making it possible to raise and lower the stage in which the stage body and steps are integrated and store it in a hangar against the wall when not in use. [Effects of the Invention]

[0006] In short, the present invention provides a stage comprising a stage body and steps arranged along at least one of the three sides and tip of the stage body, the base of the stage being pivotally attached to the floor of the stage installation room so that it can be raised and lowered to a horizontal position and an upright position, and in the upright position can be stored in a storage facility recessed into the wall of the stage installation room, the bottom plate of the stage is flush with the wall when upright and is formed so that at least the tip can be separated, so that it can protrude at a right angle as a support leg when the stage is horizontal and is rotatable so that it can fit flush as the bottom plate when upright; therefore, by simply tilting the stage, steps that are integrated with the stage body can be arranged on the outside of the stage body, which eliminates the need for separate treads or the like, improving the appearance and making it easy to install and remove the steps.

[0007] The stage is divided into a stage body and steps arranged along at least one of the three sides and tip of the stage body, and the base ends of the stage body and steps are pivotally attached to the floor of the stage installation room so that they can be raised and lowered to a horizontal or upright position, and when upright can be stored in a storage facility recessed into the wall of the stage installation room. The bottom plate of the stage consists of a first bottom plate of the stage body and a second bottom plate of the step, and at least the tip portions of these first and second bottom plates are formed to be separable so that they can protrude at a right angle as first and second support legs when the stage body and steps are in a horizontal position, and are flush with the wall when upright, and are rotatable so that they can fit flush as the first and second bottom plates when the stage body and steps are in an upright position.In addition to the above effects, when steps are not required, the stage body can be tilted down alone, so that the presence or absence of steps can be selected depending on the situation.

[0008] The steps are formed in a gate shape along both the left and right sides and the tip of the stage body, so that steps can be arranged on three sides of the stage body; the steps are arranged along one or both of the left and right sides of the stage body and are formed vertically, so that steps can be arranged on the sides of the stage body; the steps are arranged along the tip of the stage body and are formed horizontally, and the base ends of the side panels that are elongated along both sides of the stage body are pivotally attached to the floor, so that steps can be arranged on the tip side of the stage body.

[0009] The height of the center of elevation of the stage body is set higher than the height of the center of elevation of the steps, so that even if the stage body is not thicker than the steps, a difference in height between the stage body and the steps can be automatically created, allowing the storage shed to be shallow.

[0010] The height of the elevation center of the stage body is set higher than the height of the elevation center of the steps, and the elevation centers of the stage body and the steps are aligned vertically, so the thickness of the stage body and the steps can be made approximately the same, and therefore the storage facility can be made as shallow as possible.

[0011] In the inventions of claims 3 and 5, when a stage is in a vertical position, the steps are located above the stage main body, but the center of elevation is located lower on the step, so when the stage is in a vertical position, the steps are located away from the front edge of the stage main body. However, the height of the center of elevation of the stage main body is set higher than the height of the center of elevation of the step, and the centers of elevation of the stage main body and the step are aligned vertically, the thickness of the step is made thicker than that of the stage main body by at least the thickness of the base plate, and the width in the depth direction of the front edge part of the step floor plate is set so that the distance between the lower edge of the rear end of the part of the step floor plate that is closest to the front edge of the stage main body and the center of elevation of the step is at least the distance between the upper edge of the front edge of the stage main body and the center of elevation of the step when it is in a horizontal position. This makes it possible to fill the gap created by the separation, and the steps can be used safely, resulting in great practical effects. [Brief explanation of the drawings]

[0013] An embodiment of the present invention will now be described with reference to the drawings. The tiltable stage 1 according to the present invention is basically pivotally attached at its base end to the floor surface FL of the stage installation room R, so that it can be tilted up and down to a horizontal state and an upright state, and in the upright state can be stored in a storage space S recessed in the wall W of the stage installation room R. It has a stage body 2 and steps 3 arranged along at least one of the three sides and the tip of the stage body 2, and the floor boards 4 of the stage 1 are composed of floor boards 4a of the stage body 2 and floor boards 4b of the steps 3, and when the stage 1 is in the horizontal state, the upper surface of the floor board 4b of the steps 3 is configured to be lower than the upper surface of the floor board 4a of the stage main body 2, and on the back side of the stage 1, a bottom board 5 is arranged horizontally in a horizontal state and parallel to the floor board 4 of the stage 1, and when the bottom board 5 is upright, it is flush with the wall W, and at least the tip part is formed as a support leg 6 that protrudes at a right angle when the stage 1 is horizontal and is parallel to the stage 1 when it is upright, and is separable from the bottom board main body 7 that occupies the majority of the stage, and the support leg 6 is arranged so that when the stage 1 is upright, it rotates so that it fits flush with the bottom board main body 7 and becomes the bottom board 5. The specific details will be explained below. Example 1

[0014] 2(a) is a front view showing the stage main body alone in use, FIG. 2(b) is a front view showing the stage main body and steps in use, FIG. 2(c) is a plan view of FIG. 2(b), FIG. 3 is a cross-sectional view taken along line AA in FIG. 1, FIG. 4 is a cross-sectional view taken along line BB in FIG. 2(a), and FIG. 5 is a cross-sectional view taken along line CC in FIG. 2(b). In this first embodiment, the stage 1 can be divided into a rectangular, flat box-shaped stage main body 2 and gate-shaped steps 3 arranged along both the left and right sides and the tip of the stage main body 2, and the base ends of each of these steps are connected to the stage installation room R. The stage 1 is pivotally attached to the floor surface FL side, and the bottom plate 5 is made up of a first bottom plate 5a of the stage main body 2 and a second bottom plate 5b of the step 3, and the support legs 6 are made up of a first support leg 6a that is separably formed at the tip portion of the first bottom plate 5a of the stage main body 2, and a second support leg 6b that is separably formed at the tip portion of the second bottom plate 5b of the step 3, the first bottom plate 5a being made up of the first support leg 6a and the first bottom plate main body 7a, and the second bottom plate 5b being made up of the second support leg 6b and the second bottom plate main body 7b, and this stage 1 is arranged so that it can be stored in an upright position in a storage shed S recessed in the wall W of the stage installation room R.

[0015] The base end of the stage body 2 is pivotally attached to fixed legs 8, 8a that are fixed upright on the floor surface FL of the hangar S, making it possible to raise and lower the stage body 2 and making the first base plate 5a and wall W uniform in the vertical position.

[0016] The step 3 has a thickness t2 that is thicker than the thickness t1 of the stage main body 2, and preferably is thicker by the thickness of the second bottom plate 5b.When stored upright in the hangar S, the step 3 is positioned close to the outer periphery of the stage main body 2, and its base end is pivotally attached to fixed legs 9, 9a that are fixed upright on the floor FL of the hangar S, allowing the step 3 to be raised and lowered.

[0017] In order to make the storage space S recessed in the wall W as shallow as possible, the fixed legs 8, 8a are made higher than the fixed legs 9, 9a, and the center of elevation of the stage body 2 is positioned above the center of elevation of the step 3, and at the same time, the first support leg 6a of the stage body 2 is made longer than the second support leg 6b of the step 3, so that the difference in height between the stage body 2 and the step 3 is automatically formed. Furthermore, by aligning the centers of elevation and tilt of the stage body 2 and step 3 vertically and making the vertical distance between the center of elevation and tilt of the stage body 2 and the surface of the first base plate 5a the same as the vertical distance between the center of elevation and tilt of step 3 and the surface of the second base plate 5b, the surfaces of the first base plate 5a and the second base plate 5b are flush in the vertical position, and the protruding length of the first support leg 6a in the horizontal position is longer than the protruding length of the second support leg 6b of step 3 by the difference in height d between the centers of elevation and tilt of the stage body 2 and step 3.

[0018] Since the center of elevation of step 3 is set lower than that of the stage body 2, the position of the long horizontal part at the tip end relative to the stage body 2 when in a horizontal position is farther away from the stage body 2 than the position of the long horizontal part at the tip end relative to the stage body 2 when in an upright position. Therefore, the depth direction width of the long horizontal part at the tip end of the stage body 2 on floor board 4b is set wide so that it partially overlaps with floor board 4a of the stage body 2, and so that the rear end of the above part does not come into contact with the tip end of the stage body 2 when step 3 is set to a horizontal position. Specifically, it is preferable to make the distance L1 between the lower rear edge of the above-mentioned part and the center of elevation of the step 3 equal to or greater than the distance L2 between the upper tip edge of the stage body 2 in the horizontal state and the center of elevation of the step 3, and to make the value as close as possible to that distance, thereby narrowing the gap between the above-mentioned part of the step 3 in the horizontal state and the tip of the stage body 2 in the horizontal state as much as possible.

[0019] As shown in Figures 2(b), 2(c), and 5, to use the stage 1 in the stored state, first the stage body 2, which is in a vertical state, is rotated down, so that the stage body 2 becomes horizontal as shown in Figures 2(a) and 4, and the first support leg 6a, which protrudes at a right angle from the stage body 2, touches the floor surface FL. Next, the step 3, which is in a vertical state, is rotated down, and when the step 3 becomes horizontal, the second support leg 6b, which protrudes at a right angle from the step 3, touches the floor surface FL, and the stage 1 is formed with steps 3 arranged on both sides and at the tip of the stage body 2.

[0020] Furthermore, as shown in Figure 3, to store the stage 1 in an upright position in the storage shed S, the steps are reversed by first rotating the step 3 upright and restoring it so that the second support leg 6b is parallel to the step 3, so that the second support leg 6b and the second base plate main body 7b are flush with each other to form the second base plate 5b, and then the stage main body 2 is rotated upright and restoring it so that the first support leg 6a is parallel to the stage main body 2, so that the first support leg 6a and the first base plate main body 7a are flush with each other to form the first base plate 5a, and so that the base plate 5 (first base plate 5a and second base plate 5b) is flush with the wall W of the stage installation room R. Example 2

[0021] 6 is a front view showing a state in which a tiltable stage according to a second embodiment of the present invention is stored against a wall, FIG. 7(a) is a front view showing the state in which only the stage main body is in use, FIG. 7(b) is a front view showing the state in which both the stage main body and steps are in use, FIG. 7(c) is a plan view of FIG. 7(b), FIG. 8 is a DD cross-sectional view of FIG. 6, FIG. 9 is an EE cross-sectional view of FIG. 7(a), and FIG. 10 is an FF cross-sectional view of FIG. 7(b). In this second embodiment, the stage 1 is divided into a rectangular, flat box-shaped stage main body 2 and vertically long steps 3, 3 arranged along each of the left and right sides of the stage main body 2, and each of these has its base end pivotally attached to the floor FL side of the stage installation room R. The bottom plate 5 is composed of a first bottom plate 5a of the stage main body 2 and second bottom plates 5b, 5b of the steps 3, 3; the support legs 6 are composed of a first support leg 6a formed separably at the tip of the first bottom plate 5a of the stage main body 2 and second support legs 6b, 6b formed separably at the tip of the second bottom plates 5b, 5b of the steps 3; the first bottom plate 5a is composed of the first support leg 6a and the first bottom plate main body 7a, and the second bottom plate 5b is composed of the second support legs 6b, 6b and the second bottom plate main body 7b, 7b; and this stage 1 is arranged so that it can be stored in an upright position in a storage shed S recessed in the wall W of the stage installation room R.

[0022] The base end of the stage main body 2 is pivotally attached to fixed legs 8, 8a fixed upright on the floor surface FL of the storage shed S, thereby making it possible to raise and lower the stage main body 2.

[0023] Each of the steps 3, 3 has the same thickness as the stage body 2, and when stored upright in the hangar S, they are positioned close to both sides of the stage body 2, with their base ends pivotally attached to fixed legs 9, 9a that are fixed upright on the floor FL of the hangar S, allowing the steps 3, 3 to be raised and lowered.

[0024] In order to make the hangar S recessed in the wall W as shallow as possible, the center of elevation of the stage body 2 is positioned above the centers of elevation of the steps 3, 3, and at the same time, the length of the first support leg 6a of the stage body 2 is made longer than the length of the second support legs 6b, 6b of the steps 3, 3, thereby automatically creating a difference in height between the stage body 2 and the steps 3, 3. Furthermore, by aligning the centers of elevation and tilt of the stage body 2 and step 3 vertically and making the vertical distance between the center of elevation and tilt of the stage body 2 and the surface of the first base plate 5a the same as the vertical distance between the center of elevation and tilt of the step 3 and the surface of the second base plates 5b, 5b, the surfaces of the first base plate 5a and the second base plates 5b, 5b are flush in the vertical position, and the protruding length of the first support leg 6a in the horizontal position is longer than the protruding length of the second support legs 6b, 6b of step 3 by the difference in height d between the centers of elevation and tilt of the stage body 2 and step 3.

[0025] Since the center of elevation of step 3 is set lower than that of the stage body 2, the tip of the stage body 2 and the tips of steps 3 and 3 are aligned when in a horizontal position, and the tip of the stage body 2 when in an upright position is higher than the tips of steps 3 and 3 by the difference in height between the centers of elevation and depression, and accordingly, the hangar S is formed in a convex shape.

[0026] As shown in Figures 7(b), 7(c), and 10, to use the stage 1 in the stored state, first the stage main body 2, which is in a vertical state, is rotated down, so that the stage main body 2 becomes horizontal as shown in Figures 7(a) and 9, and the first support legs 6a, which protrude perpendicularly from the stage main body 2, come into contact with the floor surface FL. Next, the vertical steps 3, 3 are rotated down, and when the steps 3, 3 become horizontal, the second support legs 6b, 6b, which protrude perpendicularly from the steps 3, 3, come into contact with the floor surface FL, and the stage 1 is formed with the steps 3, 3 arranged on both sides of the stage main body 2.

[0027] Furthermore, as shown in Figure 8, to store the stage 1 in an upright position in the storage shed S, the steps 3, 3 are first raised and rotated in the reverse order, and the second support legs 6b, 6b are returned to their original position so that they are parallel to the steps 3, 3, so that the second support legs 6b, 6b and the second base plate main body 7b, 7b are flush with each other to form the second base plate 5b, 5b, and next the stage main body 2 is raised and rotated, so that the first support leg 6a is returned to its original position so that it is parallel to the stage main body 2, so that the first support leg 6a and the first base plate main body 7a are flush with each other to form the first base plate 5a, and so that the base plate 5 (first base plate 5a and second bottom plate 5b) is flush with the wall W of the stage installation room R. Example 3

[0028] 11 is a front view showing a state in which the stage can be tilted up and down according to a third embodiment of the present invention is stored on a wall, FIG. 12(a) is a front view showing the state in which only the stage main body is in use, FIG. 12(b) is a front view showing the state in which both the stage main body and steps are in use, FIG. 12(c) is a plan view of FIG. 12(b), FIG. 13 is a cross-sectional view G-G of FIG. 11, FIG. 14 is a cross-sectional view H-H of FIG. 12(a), and FIG. 15 is a cross-sectional view II of FIG. 12(b). In this third embodiment, the stage 1 is divided into a rectangular, flat box-shaped stage main body 2 and a horizontally long step 3 arranged along the tip side of the stage main body 2, and each of these steps is mounted on the floor FL of the stage installation room R. The base end of the stage 1 is pivotally attached to the side of the stage, and the bottom plate 5 is made up of a first bottom plate 5a of the stage main body 2 and a second bottom plate 5b of the step 3, and the support legs 6 are made up of a first support leg 6a that is separably formed at the tip portion of the first bottom plate 5a of the stage main body 2, and a second support leg 6b that is separably formed at the tip portion of the second bottom plate 5b of the step 3, the first bottom plate 5a being made up of the first support leg 6a and the first bottom plate main body 7a, and the second bottom plate 5b being made up of the second support leg 6b and the second bottom plate main body 7b, and this stage 1 is arranged so that it can be stored in an upright state in a storage shed S recessed in the wall W of the stage installation room R.

[0029] The base end of the stage main body 2 is pivotally attached to fixed legs 8, 8a fixed upright on the floor surface FL of the storage shed S, thereby making it possible to raise and lower the stage main body 2.

[0030] The thickness t2 of the step 3 is thicker than the thickness t1 of the stage main body 2, and preferably the step 3 is thicker by the thickness of the second bottom plate 5b. When stored upright in the hangar S, the step 3 is positioned close to the front end of the stage main body 2 and has side plates 10, 10a that are extended along both sides of the stage main body 2. The base ends of these side plates are pivotally attached to fixed legs 9, 9a that are fixed upright on the floor FL of the hangar S, making it possible to raise and lower the step 3.

[0031] In order to make the storage space S recessed in the wall W as shallow as possible, the center of elevation of the stage body 2 is positioned above the center of elevation of the step 3, and at the same time, the length of the first support leg 6a of the stage body 2 is made longer than the length of the second support leg 6b of the step 3, thereby automatically creating a difference in height between the stage body 2 and the step 3. Furthermore, by aligning the centers of elevation and tilt of the stage body 2 and step 3 vertically and making the vertical distance between the center of elevation and tilt of the stage body 2 and the surface of the first base plate 5a the same as the vertical distance between the center of elevation and tilt of step 3 and the surface of the second base plate 5b, the surfaces of the first base plate 5a and the second base plate 5b are flush in the vertical position, and the protruding length of the first support leg 6a in the horizontal position is longer than the protruding length of the second support leg 6b of step 3 by the difference in height d between the centers of elevation and tilt of the stage body 2 and step 3.

[0032] Since the center of elevation of step 3 is set lower than that of the stage body 2, the position of step 3 relative to the stage body 2 in the horizontal state is farther away than the position of step 3 relative to the stage body 2 in the upright state. Therefore, the horizontal part of floor board 4b at the tip end of the stage body 2, i.e., the width in the depth direction of the floor board 4b itself, is set wide so that it partially overlaps with floor board 4a of the stage body 2, and so that the rear end of floor board 4b does not hit the tip end of the stage body 2 when step 3 is set to the horizontal state. Specifically, it is preferable to make the distance L1 between the part of the floor board 4b closest to the tip of the stage main body 2, i.e., the lower edge of the rear end of the floor board 4b itself, and the center of elevation of the step 3, equal to or greater than the distance L2 between the upper edge of the tip of the stage main body 2 in the horizontal state and the center of elevation of the step 3, and to make this as close a value as possible, thereby narrowing the gap that occurs between the rear end of the floor board 4b of the step 3 in the horizontal state and the tip of the stage main body 2 in the horizontal state as much as possible.

[0033] As shown in Figures 12(b), 12(c), and 5, to use the stage 1 in the stored state, first the stage main body 2, which is in a vertical state, is rotated down so that the stage main body 2 is in a horizontal state as shown in Figures 12(a) and 14, and the first support leg 6a protruding at a right angle from the stage main body 2 touches the floor surface FL. Next, the step 3, which is in a vertical state, is rotated down so that the step 3 is in a horizontal state, and the second support leg 6b protruding at a right angle from the step 3 touches the floor surface FL, and the stage 1 is formed with steps 3 arranged on both sides and at the tip of the stage main body 2.

[0034] Furthermore, as shown in Figure 13, to store the stage 1 in an upright position in the storage shed S, the steps are reversed, first the step 3 is raised and rotated, and the second support leg 6b is returned to its position so that it is parallel to the step 3, so that the second support leg 6b and the second base plate main body 7b are flush with each other to form the second base plate 5b, and then the stage main body 2 is raised and rotated, so that the first support leg 6a is returned to its position so that it is parallel to the stage main body 2, so that the first support leg 6a and the first base plate main body 7a are flush with each other to form the first base plate 5a, so that the base plate 5 (first base plate 5a and second base plate 5b) is flush with the wall W of the stage installation room R.
