A tatami stage 100 is shown. This stage is placed on the frame 102. A pair of panels 104 and 106 are supported. Frame 102 includes panels 104 and 106 are substantially opposed to each other, so that the overall stage footprint is substantially reduced. It is folded up to the storage state shown in Figure 2. Panels 104 and 106 are reversible. Each side has a different surface, like a carpet surface and a non-slip surface. . The frame frame 102 has a folding section 111 and a folding section connected by a central hinge. In the state or unfolded state and in the folded position, the legs 110 are substantially straight. It has a folding link mechanism 112 that maintains an upright position. The height of stage 100 is , can be raised or lowered to obtain the desired height of the stage 100. Both can be adjusted by opening the height adjustment lever 130. Adjustment can be made by a telescoping member 128 extending from 10. inset legs 128 has a band that joins with the floor. Lifting, lowering and folding of stage 100 Folding is performed using a gas spring 1 according to the weight of the stage 100. 14. Further, since it is adjustable, panels 104 and 1 06 is adjusted by tightening the adjustment bolt 11 at the center of the folded part of the frame 102. 6.

As shown in FIGS. 3 and 4, the stage 100 is Assists in the initial folding of the stage and the final folding of the stage into the folded state. It has a folding assist device 165. Further, the folding assisting device 165 0 and panels 104 and 106, and thereby If the frame is closed completely due to inadvertence, the worker's hand or fingers may be caught between the frames. I make sure that I don't get caught. Spring 166 is mounted within the stationary member of frame 102. Support the placed floating column 170. floating tube part ortions) into the stationary member of frame 102 by slot 168. be guided. Floating strut 170 supports a portion of folding frame frame 111.

As shown in FIG. 3, when the stage 100 is in use, the floating column 170 is completely It has fallen to Spring 166 allows the stage to be A constant pressure is exerted on the struts 170 against the folding frame sill 111. death Therefore, when an initial force is applied to fold stage 100, spring 166 will fold. Push the folding frame frame 111 toward the folded state. This is at the end of folding Similar to cushions, it assists in the initial folding process.

When going from fully folded to fully unfolded, the folding linkage , a floating strut 170 supported by a spring 166 as shown in FIG. It will not be folded until it is closed. Spring 166 and tube 170 are activated until the stage is fully open. It prevents it from spinning. Therefore, as shown in FIG. To fully expand the stage, you must apply a small amount of pressure in addition to the weight of the stage. Must be. This adds a safety feature and also allows stage 100 Makes folding and setting up easier.

As shown in FIG. 5, the fittings between the frame 102 and the panels 104, 106 are formed by connectors 135 inserted into passageways 134 of panels 104,106 has been done. A passageway 134 is located near each corner of the panels 104.106; It extends through the panels 104, 106. Each connector 135 is Split from hole 146 in each support member 142 until hole 148 in frame 102 is reached. mounted on support member 142, coupled by inserting pin 144. ing. A lifting member is used to raise panel 104 relative to other panels. 150.152 are placed below the panel. The rising members 150, 152 are To extend the height of a panel without raising both panels 104 and 106.

Generally, the elevating member is 4 inches or 8 inches.

When the 8-inch raising member 152 is inserted, the raised A kickboard 154 is placed between the panel 104 and the panel 106 that is not raised. placed to cover the gap. One panel 104 on the stage A coral riser structure is achieved by raising it relative to the channel 106. This is a good thing. To create an extended coral riser , a bridge panel extended between the stains, with a top H panel 104 It is also preferable in that it can be increased.

As shown in Figure 20, when not in use, the raising members 150, 152 are It is housed on the stage frame 102. The rising member 150, 152 is a rising part. The material storage member 200 is placed on the storage shelf 198-1:. - rising member 150 and 152 are slid into the storage member 200. Next, raise the split pin 144. It slides through the member and storage member 200 and holds the elevating member in an unused position. be done.

As shown in FIG. 5, the latch members 202 are spaced apart from the bridge panel 108. It engages with the auxiliary latch member 204 to make the connection. Panel 108 is described below. As such, it is supported by a connector on stage 2'.

Here, reference is made to FIGS. 7 and 8. The connector 135 is connected to each part as shown in FIG. Passages 13 in panels 104, 106 so that they are approximately flush with the top surface of the panel. It extends through 4. The connector extends into the passageway 134 of the panel. A pin 136 extending upward from the support portion 142 is used. Part of pin 136 expands the resilient compressible portion 138. When pin 136 is rotated and tightened, Compressible portion 138 expands in diameter as shown in FIG. 8 to secure the walls of passageway 134. make it big In other words, the connector 135 and the passage 134 are fixed by friction, and the As a result, the panel is held against the frame 102. The pin 136 is connected to the passage 134 a resilient base that allows slight movement of the pin 136 for positioning within the It is placed at 140. The resilient base 140 is in the vicinity of the stop plate 141. Bae Since the pin 140 has a length greater than its width, it rotates the pin 136. Sometimes, to prevent excessive rotation of pin 136, base 14 is rotated as shown in FIG. 0 hits the stop plate 141. stage panel 104.106 With a standard screw head set of bolts for fixing to the frame 102. This is preferable because a standard square wrench can be used. Furthermore, the connector 135 Since it is an integral member attached to the frame 102 and no extra parts are required, There is no risk of losing the member when attaching the panel to the frame. Connector 1 35 is also preferred in that it is substantially coplanar with panels 104, 106.

To lock the stage in the fully open position, fold the frame as shown in Figure 9. Lock link mechanism 1 for locking folding halves 55 are provided. A locking linkage 155 is provided on each panel 104.106. It has a pair of cross links 156, 158 extending between the legs 110 from below.

The crosslink 156 has a handle 162 and a handle that raise and lower the linkage. It has a stopper 164 that holds the link mechanism 155 in a locked state. each other A linkage 155 between the opposite pair of legs extends along the center of the stage. They are connected by a member 160. Lock stage 100 in use Therefore, the lock link mechanism in the position shown in Figure 10 passes through the toggle point as shown in the phantom line. and is pushed downward. When the link mechanism 155 passes through the toggle point, the cross link The lock 158 engages the stopper 164 to prevent further folding of the linkage. Ru. Any inward pressure on the linkage will force link 158 to stop 1. 64 and is pushed, and as a result, folding of the stage 100 is prevented. Ru.

Furthermore, in order to increase the distance between the legs while adjusting the height of the stage 100, a pair of legs 110 A spacing linkage 192 is provided between and on one of the linkages 155. There is. Spacing linkage 192 is between the legs and is part of locking linkage 155. It has links 194 and 196 extending to . The spacing linkage 192 Although the stage is folded together with the stage, it prevents the stage from folding during height adjustment. Therefore, it operates together with the lock link mechanism 155.

As shown in FIG. 2, when the stage 100 is folded, the bridge panel 108 , panels 104 and 1064. Panel 108 has multiple stages. Extend the stage surface area between 100 and 100. This allows extended consecutive steps Provides a page surface without a frame under each panel. folded Save storage space by storing the bridge panel 108 above the stage. and eliminates the need for an additional wheelbarrow to move the bridge panel 108. Ste By storing the panel 108 in the page 7, it is always easy to keep it in its final state of use. It can be placed within easy reach.

The bridge panel 108 includes hook members 172 along the lower edge of the panel and It is held on the stage 100 by a hook member 174 near the second part of the handle. figure 11, the lower hook member 172 is attached to the panel 104 or 106 and the bridge. It extends beyond the zip panel 108. Hooks are located at the top of the base of the stage panel. It extends beyond the surface and supports the lower edge of the stage panel as well.

As shown in Figure 12, when the retained hook member is not in use, the bottom flap The hook member is rotated laterally around the shaft portion 175 to attach the panel 10. Slide it under 4 and 106. The hook member 172 is a spring-type release button. By coupling or disengaging the connector 176, it can be held in either the stowed or used condition. be done. A release button 176 is used to keep the hook member hidden or in use. extend through holes 177a and 177b in the mounting member. The hole 177a is a button. Because it is a little smaller than the hole 176, even if it aligns with the hole 177a, it may not be pushed down a little. This creates some resistance to rotation, but does not hide member 172. Do not lock it in a locked state.

The release button 176 fits into the hole 177b, so the hook member 172 is removed from the panel. It is pressed down by hand to rotate it from the holding state.

As shown in FIG. 13, the two-part member 174 is placed on the folding frame 111; Since each member 174 is equipped with a spring, it is strongly held against the folding frame 111. be done. As shown in FIG. 2, spring 178 moves hook member 174 toward frame 102. During storage, the upper portion 181 of the fock member 174 is biased toward the panel 1. 04.106 and the folding frame 111. When using the hand The part 180 is grabbed and the member is pulled out of the flume and removed outwardly and upwardly. Ru. Thereafter, the upper portion 181 of the hook member ]74 is attached to the - of the bridge panel 108. L, the spring 178 pulls the -L portion 181 of the hook member beyond panel 1o8. and pull it.

Hook members 172 and 174 allow for connection to additional tools or stages 100. This allows storage of the bridge panel 108 without requiring extra parts. I can do it.

As shown in FIGS. 14 to 16, the stage 100 is in use and storage conditions. It has a roller section 118 used to rotate the stage. Roller part 11 8 moves the stage up and down, so that the legs 110 are connected to and removed from the ground.

As shown in FIG. 14, when the roller section 118 is at its lowest position, the roller 12 0 is connected to the floor, and the legs 110 are sufficiently elevated from the floor, so the stage 100 is Can be rotated to various locations. When the roller section 118 is lowered , the stage 100 can be in either the folded or unfolded state. It can be rotated even if The roller portion 118 rises as shown in FIG. When the stage is in position, the legs 110 are connected to the ground and the rollers 120 completely support the weight of the stage. No, the stage never moves from its use position.

A handle 122 is attached thereto to raise or lower the roller portion 118. It is being The handle 122 is designed for storage in order to maximize its structural advantage. It can be rotated between the storage position and the use position. of the handle 122 For rotation, mounting is on a mounting beam. limited by slot 123.
