  And, in the wall storage stage of Patent Documents 1 and 2, a gap is formed between the lower end of the bottom plate and the upper end of the curtain plate in the upright state of the stage so that the stage can be elevated. Since the gap is at a relatively low position, children may injure their fingers by inadvertently pushing their fingers, or a foreign object such as a coin may be accidentally inserted into the gap, causing troubles in raising and lowering the stage. Have a problem to invite.

  Therefore, in the present invention, in a state where the stage is stood and stored in a hangar recessed in the wall, the wall storage stage that closes the gap formed between the bottom plate bottom end and the curtain top end of the stage disposed on the same plane as the wall. The purpose is to provide.

In view of the above problems, the wall storage stage of the present invention is configured to uprightly fix a fixed leg on which a curtain is placed on the same plane as the wall on the floor surface of the hangar recessed in the wall. The base plate of the stage, which can be lifted up in a horizontal state and an upright state, is pivotally attached, and the stage bottom plate in which the surface is arranged flush with the wall in the upright state of the stage has a tip portion and a central portion. In order to make the stage stand upright, one or both of them are divided and formed so that it can be pivoted so that it protrudes at right angles as a support leg in the horizontal state of the stage and fits as a bottom plate in an upright state of the stage A shutter for closing a gap formed between the lower end of the bottom plate and the upper end of the curtain plate in an upright stage is provided on the back surface of the bottom plate.
The shutter is composed of a flat plate arranged in parallel on the back surface of the bottom plate so as to be able to advance and retreat toward the fixed leg. The front end of the flat plate is slidably contacted with the fixed leg, and the advancement length of the flat plate from the back surface of the bottom plate according to the elevation of the stage. It is characterized by providing a track that regulates the height.

  In short, the present invention fixes the fixed leg with the curtain plate arranged on the same plane as the wall upright on the floor surface of the hangar recessed in the wall, and the upper part of the fixed leg has a horizontal state and an upright state. The base plate of the stage that can be lifted up and down is pivotally attached, and the stage bottom plate in which the surface is arranged flush with the wall in the upright state of the stage is divided and formed at one or both of the front end and the center. In addition, it protrudes at right angles as a support leg in the horizontal state of the stage, and is provided so as to be rotatable so that it can be flush with the bottom plate in the upright state of the stage.

It can be stored in an upright state.

The stage 1 has a floor plate 2 that is horizontally disposed in the horizontal state and a bottom plate 3 that is disposed on the same vertical plane so that the surface is uniform with the wall W in the upright state of the stage 1 in the same area. Are arranged in parallel, and an elongated strip-like side plate 4 is installed between the left and right edges of the bottom plate 3 and the floor plate 2, and an elongated strip-shaped kick plate 5 is installed between the distal ends, thereby forming a flat box shape with the base end open. Forming.
The stage 1 has a bilaterally symmetric structure, and FIG. 2 showing the inside thereof shows only the right side.

  A plurality of fixed legs 6 are fixed upright on the floor surface f of the hangar H in the transverse (left and right) direction, and a plurality of parallel fixing legs 6 are arranged on the back surface of the floor plate 2 in parallel with the fixed legs 6 on the top of the fixed legs 6. The base end portion of the joist 7 that is long in the vertical direction is pivotally attached, so that the base end portion of the stage 1 is pivotally attached so that the stage 1 can be elevated.

  Since each of the fixed legs 6 is pivotally attached to the base 1 of the stage 1 as described above with the upper end inserted into the base end 1a of the stage 1, the base 3 of the bottom plate is formed so that the stage 1 can be tilted. A recessed portion 8 whose front is opened so as to be able to intervene is provided below the pivoting portion 6a with the stage 1.

  Between the front surfaces of the fixed legs 6 at the left and right edges, a strip-shaped curtain plate 9 extending in the left-right direction is arranged on the same vertical plane so as to be uniform with the wall W.

  In addition, a crosspiece 10 (only the right side is shown in FIG. 2) installed in the middle of two joists 7 parallel on the left and right sides penetrates the joists 7 and the side plates 4 on the left and right side edges, and the side plates 4 A round drop lock 11 is provided as a stage upright holding device having a lock trough 11a that can be protruded and retracted from the outer surface, and a round hole shaped lock holder 12 into which the tip of the lock trough 11a of the round drop lock 11 is inserted and removed is a side wall of the hangar H Provided in H1.

  The bottom plate 3 has one or both of a tip portion and a center portion (in the illustrated example, two locations of the tip portion and the center portion) and is formed in a panel shape having a horizontal width equal to the bottom plate 3 in the horizontal state of the stage 1. The support leg 3a protrudes at a right angle, and is rotatably provided so as to be flush with the stage plate 1 as a part of the bottom plate 3 (arranged on the same plane).

  The support leg 3a is pivotally attached with a hinge portion provided at a suitable position of the joist 7 on the back surface of the base end, and a damper 13 in which a rod 13a is extendable and retractable between a plurality of brackets provided at appropriate positions on the back surface of the support leg 3a and the floor board 2 is provided. A grounding portion 14 having an adjustable protrusion length is provided at a plurality of locations on the back surface of the distal end portion of the support leg 3a.

  In addition, a communication port 15 communicating with the inside of the stage 1 is opened at a portion of the bottom plate 3 where the central support leg 3a is bent, and a round lock 11 is disposed inside the stage 1 in the vicinity of the communication port 15. It is set to be done.

  In the upright state of the stage 1, a slender gap S of a horizontal line is formed between the lower end (base end) of the bottom plate 3 and the upper end of the curtain plate 9 so that the stage 1 can be raised and lowered.

  Since this gap S is formed at a relatively low position from the floor surface f, the child may inadvertently hurt his / her fingers and get injured, or mischief may cause foreign objects such as coins to be hindered. In the wall storage stage 1 according to the present invention, a shutter 16 that closes the gap S is provided on the back surface of the bottom plate 3.

  The shutter 16 is composed of a flat plate 16 arranged in parallel on the back surface of the bottom plate 3 so as to be able to advance and retreat toward the fixed leg 6. 3. A track 17 is provided for variably regulating the advancement length of the flat plate 16 from the back surface.

  As shown in FIGS. 3 and 7, the flat plate 16 is a metal plate formed in a strip shape having the same length as the interval between the side plates 4 and having a predetermined length (the length between the distal end and the proximal end). The bottom plate 3 is suspended by a square pipe-shaped horizontal hand rod 18 fixedly disposed so as to be arranged in parallel at a predetermined interval from the base end (lower end in FIG. 7) of the bottom plate 3.

  The base end (upper end in FIGS. 3 and 7) of the flat plate 16 is provided with a flange portion 16a bent at a right angle so as to be directed to the floor plate 2, and a plurality of support shafts 19 are provided in the longitudinal (left and right) direction of the flange portion 16a. It protrudes upwards toward the horizontal hand bar 18 at predetermined intervals.

  The support shaft 19 is composed of a bolt provided with a screw portion only on the distal end (lower end) side, and passes through the bolt 19 so as to be orthogonal from the upper side to the lower side in FIGS. ) Side non-threaded portion is slidable with respect to the horizontal hand rod 18, and the flange portion 16a is sandwiched between a nut and a high nut screwed to the screw portion, and the stage 1 stored in the hangar H In the upright state, the bolt head 19a at the upper end formed with the retaining portion 19a is seated on the upper surface (seat surface) 18a of the lateral lever 18 so that the flat plate 16 that advances with the maximum extension length by its own weight closes the gap S. It is made up of.

  The track 17 is composed of a curved lower side edge 8a of the recessed portion 8 of the fixed leg 6 and a rear side edge 8b continuously formed vertically upward at the rear end of the lower side edge 8a. Accordingly, when the stage 1 is rotated, the flat plate (shutter) 16 comes out by its own weight by changing the advancement length of the flat plate 16 by being pressed along the track 17 in which the tip of the flat plate 16 is slidably contacted. The stage 1 can be smoothly rotated without being hindered by various places around the pivotal part 6a of the fixed leg 6 pivotally attached to the base 1 of the stage 1 in the state of being left open. It is regulated to let you.

  The stage 1 of the present embodiment may be provided with a large number of stay dampers and a large number of assisting means (not shown) as a stage support device (not shown) in the same manner as in Patent Documents 1 and 2.

  In the stage 1 configured as described above, in the upright state housed in the hangar H, the lock hook 11a of the round drop lock 11 protrudes from the outer surface of the side plate 4 and its tip is provided on the side wall H1 of the hangar H. The stage 1 is kept upright and is prevented from falling down, and the stage 1 does not fall inadvertently and is safe.

  In the upright state of the stage 1, the bottom plate 3 is exposed so that the surface thereof is arranged on the same plane as the wall W, and the stage plate 3 has a lower end (base end) and a curtain plate 9 between the upper end of the stage plate 9. A slender gap S of a horizontal hand for forming 1 to be able to be raised is formed at a height that can be reached by a relatively low child's hand from the floor surface f.

  On the back side of the bottom plate 3, the shutter 16 in a suspended state from the lateral hand rod 18 through the support shaft 19 closes the gap S, so that a finger or a foreign object is inserted through the gap S. This prevents dangers and malfunctions such as injury to fingers and poor raising / lowering of the stage.

  In order to transform the stage 1 in the retracted state into a stage, first, the support leg 3a integrated with the bottom plate 3 is projected at right angles so as to bend with respect to the bottom plate 3.

  Next, the round drop lock 11 is operated through the communication port 15 to immerse the lock rod 11a having the tip inserted into the lock receiver 12 into the stage 1 to release the fall prevention state of the stage 1 in the upright state.

  Thereafter, the stage 1 is turned over and grounded, and the grounding portion 14 protruding from the tip of the support leg 3a is grounded on the floor surface f, thereby forming a stage in which the floor board 2 is horizontally arranged on the upper layer.

  When the stage 1 is tilted from the upright state, the leading end of the flat plate 16 is pressed along the track 17 in sliding contact with the tilt, so that the length of advancement of the shutter 16 can be varied.

  As a result, when the stage 1 is rotated, the stage 16 is rotated by being caught in various places around the pivoting portion 6a of the fixed leg 6 pivotally attached to the base 1 of the stage 1 with the shutter 16 being released by its own weight. The stage 1 can be smoothly rotated without disturbing the movement.

  In order to store the stage 1, the stage 1 is turned upside down in the reverse procedure, the lock rod 11a of the round drop lock 11 is inserted into the lock receiver 12, and the support leg 3a is integrated with the bottom plate 3. It can be achieved by reinstating.
