Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a retractable staircase-like device installed on a part of a flat wide area for holding various sports and events inside a gymnasium, multipurpose hall, etc. The present invention relates to a system for free location (free position selection) of individual floors in a stepped movable floor assembly, which collectively refers to the bleachers or the floor structure, which can be expanded and contracted.

[Conventional technology]

Conventionally, this type of stepped movable floor assembly extends its entire volume from a storage recess provided in a part of a wide area surface to a holding area for sports and events at the central position in front. The drawer stroke of each movable bed was fixed at the same time. Therefore, the unit length used in this stepped moving floor assembly (the length when the retractable stepped bleachers or the retractable floor structure is extended into a podium shape) was constant.

[Problem to be solved by the invention]

Conventional stepped moving floor assemblies have the following problems. Sports and events held in wide-area venues require different visibility conditions for spectators depending on the content (visibility conditions within the permissible range for the distance, height, and viewing angle that allow the content to be viewed with interest), but conventional steps are not enough. Since the drawer stroke of each stage in a movable floor assembly is constant, depending on the content and number of spectators of the sport or event, it may not be possible to obtain consistent visibility conditions and seating size that match the content and number of spectators. Audiences who cannot meet these conditions will be dissatisfied,
There was a problem in that the content of sports and events to be held was restricted.

The purpose of this invention is to change the drawer stroke of the movable floor according to the content and number of spectators of sports and events held in a wide area, or to move the entire floor in this manner. The location or the overall seating size can be set freely, and the proximity, height arrangement, and viewing angle of the desired floor or overall floor to the event area can be smoothly and easily ensured based on the most common visibility conditions and audience seating size. To provide a free-port casing system for individual floors in a step-shifting floor assembly that allows the user to move.

[Means to solve the problem]

In order to achieve the above object, in the free location system of the individual floors in the stepped movable floor assembly of the present invention, a pair of left and right bases are installed in a horizontal structure with rollers at the bottom and supports at the top. By combining a plurality of movable floors connected and assembled by beams, by making the spacing between the bases and the height of the supports different for each movable floor, and making it possible to sequentially nest the movable floors, In a stepped movable floor assembly that can be extended like a dais to the holding area when in use, the degree of proximity, height arrangement, viewing angle and audience seating size of the individual floors or the entire floor to the holding area mentioned above is determined by the interconnection of the floors. It is set based on the state. In order to arbitrarily set the proximity, height arrangement, viewing angle, and seating size of each stage of the movable floor to the venue area, individual stacking devices or intermediate drawer stopper devices installed on the base side ( For example, Utility Publication No. 62-54153.
2-126454, 62-133843, 60-1
24462, 62-46747, 62-23950
, 62-23951, 63-21371. 59-117754, 63-16778).

In order to further increase the desired degree of proximity, height arrangement, and viewing angle of the tiers to the event area, for example, the movable floor of each tier is a 1-tier, 2-row type movable floor, and the first half of the When the first half is a flat floor surface and the second half is a raised floor surface, or when the first half is a flat floor surface and the second half is a raised floor surface of the storage compartment, the flat floor surface of the desired tier is placed on the raised floor surface of the previous tier or when the rear half is a raised floor surface of the storage compartment. They are now placed overlappingly on the raised floor surface of the warehouse using half-stroke operations.

In addition, in order to further increase the proximity, height arrangement, and viewing angle of the desired floor or the entire floor to the event area, for example, the movable floor of each stage has been changed from a single flat floor surface. In this case, the desired floor is placed either by overlapping the front floor or by moving the entire floor.

Furthermore, when the movable floor in each tier is in such a manner that a chair can be placed on the floor surface to sit on, the unit length and positional relationship of the total amount used by this floor surface are determined at the top of each tier. The length of the desired usage unit can be expanded or contracted by arbitrarily setting or changing the floor surface based on conditions such as the usage scale of the venue area, the audience seating size, and the viewing angle of individual floors. It has been made possible to obtain tiered seating.

In addition, when the movable floor in each tier is connected in the form of a bare platform with no chairs placed on the floor surface, the unit length and positional relationship of the total amount used by this floor surface are shown at the top of each tier. The length of the desired usage unit can be expanded and contracted by arbitrarily setting or changing it based on the floor surface on which it is located, taking into consideration the scale of use of the venue area and the viewing angle of each floor, etc. It is now possible to obtain a floor structure.
In addition, the reference position of the free location on each individual floor when used as a viewing seat is set by the chairs that are assumed to be seated, which are placed on the floor surface of each step.

The stack device, which sets the degree of approach, height arrangement, and viewing angle of each stage of the movable floor to the holding area, is attached to the tip of the trailing base other than the first stage, and is attached to the base of the forward face of the support of the leading base. It consists of a single stopper that locks, and a double stopper that is attached to the front end surface of the base adjacent to the single stopper and locks to the front end of the preceding base when the stopper is tilted down.

Furthermore, on the floor of each tier to be used as spectator seats,
It is preferable to arrange either an installed chair that can be folded and raised for storage on the floor surface of each step, or a removable chair that can be carried in and taken out.

[Operation] Since the above system is performed by individual stacking devices or intermediate drawer stomper devices installed on the base, the drawer stroke of the movable bed at each stage can be changed arbitrarily by combining operations on these devices. can.

First, when using a stepped movable floor assembly, if the proximity, height arrangement, and viewing angle of individual floors to the event area are to be maintained under the original location according to regulations, all movable floors should be pulled out. There is no need to change the stroke.
Therefore, in that case, if you leave the stacking stopper (or the free stopper of the intermediate drawer stopper) of the stacking device installed on each base unset, when using the stepped movable floor assembly, When each movable bed is sequentially pulled out from the front side to the front side, the stopper of the trailing base locks with the base of the forward face of the column of the immediately preceding base, so this leading base moves the entire length of the pull-out stroke. When the moving bed reaches the position, the next stage of moving beds will start moving forward. Therefore, by continuing this mode, all the moving beds will be extended into a uniform pedestal shape with intervals according to the specified drawer stroke. can do.

'Next, when only the movable floors located on the rear side of the stepped movable floor assembly are uniformly increased in their proximity to the event area, height arrangement, and viewing angle, the original location is changed. This objective can be achieved by changing the drawer stroke of the rear movable floor by, for example, halving it before the step movable floor assembly is pulled out. In other words, if the intermediate drawer stopper device installed on each base of the rear side movable floor is set in advance, the movable floors other than the rear side will advance to the full drawer stroke position, but the When the supporting column of the movable floor located at the rear side moves forward by a half-length than the movable floor located at the head of the rear side, it locks with the intermediate drawer stopper device set on the side of the movable floor at the head of the rear side. , the leading moving bed on the rear side will start moving forward from this half-body-height part. Therefore, from this point on, the following moving beds, including the first moving bed on the rear side, are in a state where each drawer stroke is uniformly changed to half the specified amount (
It can be extended into a podium (drawn out state) by half stroke.

In addition, depending on the content of sports and events in the event area, the proximity, height arrangement, and viewing angle of all movable floors to the event area may be increased to uniformly change the original location. , before pulling out the stepped moving floor assembly,
By placing the intermediate drawer stopper device installed on the base of all movable floors in a uniform half-drawer state, all movable floors can be set in a state where each drawer stroke is changed to half the specified amount (half). It can be extended into a pedestal shape (drawn out state) by a stroke.

〔Example〕

Embodiments of the present invention will be described below with reference to the accompanying drawings.

The stepped movable floor assembly, which is the basis of this invention, is a retractable staircase-like bleachers in which chairs 6 are arranged on the movable floor 5 of each tier as shown in No. 1, and a movable floor assembly of each tier as shown in FIG. This is a general term for an extensible floor structure with no chairs on the floor 5.

A stack device E and an intermediate drawer stopper device (not shown) for setting each drawer stroke in the above-mentioned telescoping stepped bleachers and the extendable floor structure are installed in the main part of the base 1 to be described later. There is.

Stepped moving floor assembly A1 on which the stacking device E described later is installed
The basic skeleton of is constructed as follows. That is, the first
As shown in the figure and Fig. 13, when in use, the entire stepped moving floor assembly A1 is moved from within the storage recess D at the corner of the wide area B to the holding area C for sports, events, etc. in front of it. In order to be able to move toward the target, a support 3 having a height corresponding to each stage is erected on the rear upper surface of a pair of left and right bases 1 equipped with rollers 2 at the bottom. connects horizontal beams 4 having a U-shaped cross section, and
On this beam 4, there is a one-stage, two-row movable bed 5
A plurality of movable floors 5 are mounted and assembled into a single unit, and each movable floor By connecting the 5 pieces together, they can be combined so that they can be stored in a nested manner when not in use, and can be extended like a podium towards the front holding area C when in use. ．． As shown in FIG. 13, the stacking device E consists of a single stopper 7 and a double stopper 8. The square single stopper 7 is formed by bending a band-like plate into a key shape (inverted L-shape). This single connection stopper 7 is
Attached to the tip side of the succeeding base 1 other than the first stage,
When pulling out the stepped moving floor assembly A+, when arranging the moving beds 5 in the front and rear directions with a pull-out stroke of the unit length of the base l without overlapping the movable floors 5, the preceding base 1
The base of the forward facing surface of the support column 3 is protruded on the path thereof so as to be engaged therewith.

Further, the double-tie stopper 8 is attached to the tip end surface of the same base 1 adjacent to the single-tie stopper 7 in the following manner. That is, as shown in FIG. 13, on the front end surface of the base 1 as described above, on the side closer to the preceding base l adjacent to the inside, there is a rectangular overlapping stopper 8 centered around the support shaft 8a at the lower end. It is mounted so that it can swing freely from side to side. Note that a support piece 10 is provided protruding from the center of the upper part of the front end surface of the base l to prevent the overlapping stopper 8 from falling to the right. A movable pin 9 is provided on the upper part of the above-mentioned overlapping stopper 8 so as to project forward.

Further, a fixing pin 11 is provided at the lower part of the front end face on the side facing the heavy-duty stopper 8 so as to protrude forward. A tension spring 12 is suspended between the movable pin 9 of the double stopper 8 and the fixed pin 11. Therefore, when the movable pin 9 is above the support shaft 8a, the double stopper 8 is pressed against the support piece lO of the base 1 by the elastic tension of the tension spring 12, but the movable pin 9 is The movable bin 9 is placed on the support shaft 8a.
When the stopper 8 is below the tension spring 1
Due to the traction force of the bullet 2, the bullet protrudes onto the path of the adjacent preceding base 1. Therefore, the forward movement of the preceding base 1 is prevented, thereby eliminating the drawing stroke of the preceding base 1. Although not shown, the intermediate drawer stopper device is disclosed in Japanese Unexamined Utility Model Publications No. 62-54153 and No. 62-126454. 62

747, 6 2-2 3 9 50, 62-239
51. 63-21371. By using the same 59-117754 and 63-16778, by setting the front and rear spacing of the moving bed 5 at the desired stage to be half the specified drawer stroke (or any reduction),
By increasing the proximity, height arrangement, and viewing angle of the floor 5 to the holding area C by a desired amount, a variable pedestal shape can be obtained, or each drawer stroke of all movable floors 5 can be uniformly adjusted to a specified value. By setting the amount to half, the above-mentioned degree is uniformly increased, and a free location (position selection) such as obtaining a steep pedestal shape is possible.

In the above-described free location selection, the usage unit length of the stepped movable floor assembly A+ differs depending on the usage scale of the event area C and the seating size of the number of spectators for this event area C. That is, as shown in Fig. 1 and Fig. 2 (a),
When the venue area C set in the center of the wide area area B is a very small venue area CI depending on its content and the number of spectators is large, the total used audience seat scale length (all single length) XAS1 or YAS1.In this case, the former XAS1 is 1
It uses a two-row type moving floor 5X, and the latter YA
S 1 uses an 1-stage, 1-row type moving bed 5Y.

When the number of spectators is somewhat small and the viewing angle of the rear half is to be increased, the rear overlapped seat size length (single double length) XSW'+ or YS shown in Fig. 1(b) or (e) is used.
It will be used for a somewhat short period of time in Wr. If this usage pattern is a small event area C2 where the content of the event requires a somewhat expanded area, as shown in FIG. 2(b), the stepped movable floor assembly A
1 is moved back to a position where the rear part of the stepped movable floor assembly A+ contacts a part of the storage recess D in accordance with the amount of expansion of the small holding area C2.

If the number of spectators is even smaller and the viewing angle of all seats is to be increased, all seats with overlapping seat size and length (all double length) shown in Figure 1 (C) or (f) X A W l or Y
It will be used as a short length in AWI. In this form, as shown in Fig. 2 (C), when the content of the event is a medium holding area C3 that requires further expansion, the entire stepped movable floor assembly Al is adjusted to the amount of expansion of the medium holding area C3. Then, the rear part of the movable floor assembly A1 is moved back to a position where it touches a part of the storage recess D.

If the content of the event is further expanded and requires a large event area C4 as shown in Figure 3 (al or (dl), and the number of spectators is small, (thick double length) XTW+ or YTW 1. If this shortest usage does not require the height of the viewing angle, please refer to Figure 3 (bl or (e)
Length of front and rear stacked seats shown in l (single thick length)
It becomes like XSTz or YST1.

Furthermore, as shown in Fig. 3 (C) or if), when the venue area C is the maximum venue area C5, the use of the stepped movable floor assembly A1 on the wide area surface B is discontinued, and the unique Fixed seats (fixed seats shown at the left and right ends of the figure) will be used. In this case, the stepped moving floor assembly A+
The whole is stored in a vertical shelf state under the movable floor 5 at the top in the specified section of the storage recess D according to the mode of all unused space (all-sick) XATI or YATR. .

In addition, in the stepped movable floor assembly Al that becomes the retractable stair-shaped bleachers, chairs 6 will be placed on each movable floor 5, but in this case, the chairs 6 may be installed or they may be brought in and out. The configuration of each moving bed 5 is different depending on the type of movement. That is, FIG. 6 shows a one-stage, two-row type movable floor 5X in which two rows of chairs 6 are arranged on one floor.

The first half of the movable floor 5X is shaped like a flat floor surface 5a, and an installation chair 6A that can be folded up and down at this position is arranged at the rear of this flat floor surface 5a. The latter half of the flat floor surface 5a as described above is a raised floor surface 5 that is one step higher.
An installation chair 6A, which can be folded and raised in the same manner as described above, is arranged at the rear of the raised floor surface 5b.

FIG. 7 also shows a one-stage, two-row type movable floor 5X in which two rows of chairs 6 are arranged on the 17th lower. The first half of this moving floor 5X is shaped like a flat floor surface 5a similar to that described above. The second half of this flat floor surface 5a is a storage storage raised floor surface whose upper surface is one step higher than the first half flat floor surface 5a, in order to store an installed chair 6A similar to that described above in the internal air space behind the front part with the front part openable. It is shaped by 5C. In this case, the chair 6A installed on the flat floor surface 5a is arranged at the front opening position of the raised storage surface 5C so as to be able to rise and fall. When this chair 68 is not in use,
The storage compartment has a raised floor surface 5 in the rear position by folding and tilting operations.
It is configured to be stored in C. Storage cabinet high floor surface 5
At the upper position of c, an installed chair 6A similar to the above is arranged so that it can be folded up and down at this position. The flat floor surface 5a can be configured so that it can be used as a side passage or a chorus stand by storing the installed chairs 6A in the raised floor surface 5c of the storage compartment.

FIG. 8 shows a one-stage, one-row type movable floor 5Y in which one row of chairs 6 is arranged on one floor. This moving floor 5Y is 1
The floor is shaped like a uniform flat body with no height differences.

In this case, the installed chairs 6A similar to those described above are arranged to be stored in an exposed state by folding and tilting operations for each floor surface.

Figure 4 shows that when chairs 6 are not permanently installed on the floor, all the tiers can be used as a retractable floor structure, and when the removed chairs 6B are brought into this floor, all the tiers can be used as a retractable floor structure. This figure shows a shared stepped movable floor assembly A2 that can be used as a retractable stepped viewing seat. The movable floor 5 of this shared step movable floor assembly A2 is shown in FIGS. 9 to 12.
As shown in the figures, the first half of the floor is a flat floor surface 5a and the second half is a raised floor surface 5b, similar to the above.
The moving floors are classified into two types: row-type moving floors 5X and single-stage, single-row moving floors 5Y in which the entire area of the floor is shaped like a flat floor surface 5a.

The one-stage, two-row type moving floor 5X has a flat floor surface 5a and a raised floor surface 5.
Removal chairs 6B are arranged on both sides of b so that they can be carried in and taken out. In addition, the 1-stage, 1-row type movable floor 5Y has 1 row per floor.
A removal chair 6B for the body is similarly arranged so that it can be carried in and taken out. In addition, in FIG. 4 (al), the right side movable step floor assembly A2 is used as a viewing seat by arranging the removed chairs 6B, and the left side movable step floor assembly A2 is used as an exhibition stand. This figure shows how it is used as a.

FIG. 5 shows a shared step moving floor assembly A2 according to the above.
This example shows the use of a floor structure as a dedicated expandable floor structure. This shared step moving floor assembly A2 is
Similar to the above-mentioned retractable staircase-shaped bleachers, when in use, the entire seat is moved from inside the storage recess D, which is in the corner of the wide area surface B, onto the wide area surface B in front of it, as shown in Figure 5 (a). It is constructed so that it can be pulled out and used, for example, as an exhibition stand or other stepped stage. Therefore, although not shown, this shared step moving floor assembly A2
A stacking device E similar to that shown in FIG. 13 and an intermediate drawer stopper device (not shown) are also installed on the base 1 side in the same manner as described above. However, in this shared step moving floor assembly A2, the drawer stroke for setting the prescribed interval before and after each moving floor 5 is half that of the step moving floor assembly A1 of the telescopic stepped bleachers. It is strictly prohibited to do so. In addition, when the one-unit drawer/pull-out stroke of the stepped movable floor assembly A+ of the retractable stair-shaped bleachers described above is, for example, 1.800 mm, the one-unit drawer stroke of the shared stepped movable floor assembly A2 is: 900
It is set to mm.

Next, when using the stepped movable floor assembly A+ as a retractable stair-shaped spectator seat, the reference position of free location on the individual floor 5 is set by the chair 6 to be seated placed on the floor surface of each step. It is structured like this. Therefore, in the location shown in Fig. 2 Ta), the size of the holding area C1 is almost the same as the holding area C in Fig. 1 Tal, and the extent of its extension is the same as in Fig. 1. Since the stroke is maintained, the structure is such that a location similar to that shown in Fig. 1 can be secured.

Also, as shown in Figure 2 (b), the event area C2 is Figure 2 fa)
Even if the stepped movable floor assembly A1 is slightly enlarged than the minimum holding area Cl of
Since l is the same as that in FIG. 1(b), the structure is such that the location in FIG. 2(b) can also be secured as the same location as fb) in FIG. 1. Therefore, the second
Figure (Even if the holding area C3 is further expanded as in Cl,
In the same manner as described above, the location of the used unit length X A W l in FIG. 2(C) in the stepped moving floor assembly A1 can also be secured to be the same location as in FIG. 1 fc). It is being organized.

However, as mentioned above, the reference position in setting the location is the chair 6 to be seated placed on the floor surface of each step, so for example, as shown in FIG. When stacked unused,
Under the usage unit length X T W l which is the sum of the movable floors 5 made up of sittable chairs 6, it is possible to secure a location where the visibility conditions of the movable floors 5 on the rear side of this embodiment are greatly improved. It is organized by Furthermore, in Figure 3, the unused movable floors 5 are piled up in the rear half of the stepped movable floor assembly A1, but the movable floors 5 in the front half where the chairs 6 are located do not meet the specified length. Since it is in the form of a drawer stroke, even if its usage unit length XST1 is short,
This stepped moving floor assembly A1 is constructed so that the visibility conditions of the moving floor 5 on its front side are the same as those on the front side of FIG. 1 (5) and FIG. 2 (al). has been done.

Further, as shown in Fig. 5, the movable floor 5 of each stage is a retractable floor structure without chairs on the floor surface, and when necessary, a removed chair 6B is temporarily placed on the movable floor 5 as shown in Fig. 4. In the case of the shared stepped movable floor assembly A2 that also serves as stepped seating, the drawer stroke for setting the front and back spacing of each moving floor 5 is the same as that of the stepped movable floor of the retractable stepped grandstand described above. Since it is half as much as the collective AI,
Even if all the movable beds 5 are extended at regular intervals of the drawer stroke as shown in Fig. 5(a), if the number of all stages is small, the unit length Y A S 2 used is as shown in Fig. 4. The unit length used in (a) is somewhat shorter, similar to Y A S 2. Therefore, in order to make the visibility condition for the movable bed 5 of a desired stage in this shared step movable bed assembly A2 even better than before the duplication, when raising the height by a desired amount, it is necessary to Tie stopper 8
As shown in FIG. 5(b), for example, as shown in FIG. The structure is such that an extensible floor structure having a usable unit length YSW2 in this embodiment can be obtained by the sum of the total floor surface amounts.

〔Effect of the invention〕

Since this invention is structured as described above, it has the following effects. The stepped movable floor assembly of the present invention using telescoping stepped bleachers or a retractable floor structure can move a desired stage by changing the drawer stroke of the movable floor by operating a combination of a stacking device and an intermediate drawer stopper device. Location on the floor (
Since the location can be freely selected, the S-shaped structure of the above-mentioned aggregate can be formed into a variety of combinations to suit the content of sports and events held in a wide area. I can do it.

Therefore, by securing this free location, the proximity to the venue area, height arrangement, viewing angle, and seating size of the desired movable floor in each stage can be adjusted within the permissible range under good visibility conditions. This greatly improves the functionality of this type of stepped movable floor assembly, increases the satisfaction of spectators who use this assembly, and makes it easier to hold events in gymnasiums and multipurpose halls. Since sports and events can be held without restrictions, the economic benefits of gymnasiums and multipurpose halls equipped with this stepped movable floor assembly can be further increased.
