Description

  The present invention relates to a fall prevention system for a cabinet or the like. The "overturn prevention system" can also be called "overturn prevention device" or "overturn prevention equipment". Moreover, this invention can also be regarded as "indoor facility in which fall prevention of furniture was given" or only "indoor facility". Furthermore, as cabinetware, box-shaped furniture such as a cabinet can be mentioned as a representative, but it includes various devices installed indoors, such as servers, switchboards, complex machines and the like.

  There is a cabinet as a representative of storage furniture, but the cabinets are prone to overturning in the event of an earthquake because their height is large with respect to the plane area. Therefore, many methods have been proposed to prevent cabinets from falling during an earthquake. As a fall prevention means, there is a method to make it difficult to fall down by the same effect as increasing the width of the cabinets, and as an example, Patent Document 1 discloses that the cabinet is mounted on the table on which the cabinets are mounted. It is described to provide an anti-tip plate (outrigger).

  However, in Patent Document 1, since the anti-falling plate is exposed on the floor, there is a problem that it is easy for people to grind it, or a problem that the appearance is not good. Height is high, so the problem has not been solved.).

  Therefore, Patent Literatures 2 and 3 disclose that the overturn preventing member is disposed inside the floor. That is, first, when patent document 2 is described, this patent document 2 is applied to a Japanese-style room, is the member which arrange | positioned the support plate projected on the front side of storage furniture under the tatami and integrated with the support plate. It supports storage furniture. On the other hand, in Patent Document 3, a part of the access floor is removed, and an anti-collision plate having a projecting part is disposed in front of cabinets, and the projection part of the collapsing panel is a dedicated floor panel (floor board). Covering.

  Although patent documents 2 and 3 can exhibit a fall prevention function, since a member for exclusive use is needed, construction is troublesome. Moreover, when considering individually, first, since patent document 2 presupposes the Japanese-style room in which a tatami mat was laid, there also exists a problem that it can not apply to an office etc. and it is inferior to versatility.

  On the other hand, Patent Document 3 targets the access floor and is therefore highly adaptable to the office etc., but it is troublesome to do the work because the access floor has to be partially changed, and the practicability is high I can not say.

  The present invention has been made in view of such a current situation, and an object of the present invention is to provide a furniture fall tip system which is easy to install and is excellent in practicality and versatility.

The present invention relates to a fall prevention system for furniture, the system comprising
“On the access floor, where groups of floor panels in plan view are laid in line, fixtures are placed back-to-back against partitions or other indoor equipment or building walls,
And, in the event of an earthquake, there are provided fall prevention means for preventing the fixture from falling to the front of the partition or other indoor equipment or the wall of the building. "
It is the basic composition of.

And in claim 1, in the above basic configuration,
"The overturn prevention means includes the partition or other indoor equipment or building wall as a floor panel pressing element, and the floor panel pressed by the pressing element, the lower end of the fixture is a screw or other fastener It is fixed by.

The present invention can be embodied in many ways. As an example, in claim 2,
"A row of floor panels is held down by the partition, and the fixture is screwed to the floor panel held down by the partition"
It has the composition.

Moreover, in claim 3, in claim 1,
"The fixtures rest on a plate placed on the floor and the floor panel is held by the plate by securing the plate to the partition or other indoor equipment or the wall of the building, and The lower end of the fixture and the plate are screwed together to the floor panel located below it. "
It has the composition.

In claim 4, in any one of claims 1 to 3,
"At least the upper surface of the floor panel is made of a metal plate, and the lower end of the fixture is fixed to the floor panel by a self-piercing screw"
It has the composition.

Furthermore, in claim 5, in any one of claims 1 to 4,
"The fixture has a body and a base that supports it from below, and the base is fixed to the floor panel with the screws or other fasteners."
It has the composition.

  Each invention of this application utilizes the floor panel which is a component of an access floor, and a partition or indoor facilities as a fall prevention member, and construction which removes a part of an access floor like patent documents 3 is unnecessary. As a result, the present invention is excellent in realism, and the cost can be significantly suppressed as compared with Patent Document 3.

  Furthermore, since the fixtures are disposed on the access floor, the placement position of the fixtures can be set arbitrarily, so that the freedom of the layout of the fixtures is not impaired, and the fixtures can be removed. Even if the layout is changed, no restoration work is necessary. These points are the great advantages of the present invention, and the benefits that users can receive are extremely large.

  The partition used in the present invention is preferably one fixedly held on the ceiling surface. That is, the partition has a structure in which the ceiling is stretched by a bolt or the like, or the top rail of the opening C-shape is fixed to the ceiling and the upper end of the partition panel enters the inside of the top rail Preferably, the structure is Even if the partition is not fixed to the ceiling, it has a fall preventing function sufficiently when it is held so as to be in a cross shape in a plan view or a T shape so as not to fall down.

  Other fixtures such as a cabinet may be considered as the indoor equipment. That is, for example, when the cabinets are arranged back to back, the two cabinets can be fixed via the floor panel to cooperate with each other to exhibit the fall prevention function.

  When the configuration of claim 2 is adopted, since it is possible to prevent the falling of the fixtures by utilizing partitions and indoor equipment which are a part of indoor facilities, no additional members are required, and the cost can be suppressed and the time and effort for construction are reduced accordingly. it can.

  For example, the partition is disposed near the boundary of the floor panel in plan view, and the floor panel on which the partition rests is different from the floor panel on which the fixtures rest. Then, even if the fixture is fixed to the floor panel, it is considered that the floor panel rises with the fixture during the earthquake and the fall prevention function of the fixture is not exhibited.

  On the other hand, if a plate is used like Claim 3, since a fixture and a partition or an indoor installation or a wall of a building and a floor panel are fixed via a plate, the pressing function of the floor panel by a partition etc. Can be put to good effect, and the fall prevention of furniture can be assured. Therefore, the configuration of claim 3 can further promote the freedom of the layout of the fixture.

  The invention of claim 2 does not exclude the use of a plate. The use of the plate according to the configuration of claim 2 can further improve the fall prevention function.

  As a fixing means of the fixture, a screw is preferable from the viewpoint of the fastening force, but when using a self-piercing screw as in claim 4, processing of the pilot hole is unnecessary, so The time and effort can be significantly reduced. Specifically, drill screws or tapping screws can be used as the self-piercing screw.

  Cabinets are most prone to tipping over in the office, and there are many cases in which they are installed, but these cabinets often have a base mounted on the base. In claim 5, the base is fixed to the floor panel by utilizing this point. Therefore, the fall prevention system can be easily realized by the construction procedure of fixing the base to the floor and then mounting the main body on the base.

(1) Outline of First Embodiment Next, an embodiment of the present invention will be described based on the drawings. Each of the following embodiments is applied to the fall prevention of a cabinet formed in a rectangular shape in plan view. In the following, front and rear, right and left wording are used to specify the direction, but the depth direction of the cabinet 1 (the short direction in plan view) is the front and back direction, and the frontage direction It is the direction. First, a first embodiment applied to the overturn preventing system of the steel cabinet 1 will be described with reference to FIGS. 1 to 7.

  The floor of the room is constructed on the laid access floor 3 in which a large number of floor panels 2 in a square shape in plan view are arranged in rows and columns. A partition 4 is arranged on the access floor 3 and back-to-back with the partition 4 The cabinet 1 is arranged in the state of. Although only one cabinet 1 is shown in FIG. 1, a large number of cabinets 1 are often arranged in parallel along the front surface of the partition 4 as shown in FIG. 2.

  The cabinet 1 includes a cabinet main body 5 opened forward, a horizontally pivotable double door 6 that opens and closes the opening, and a steel plate base 7 on which the cabinet main body 5 is mounted. The rear surface (rear surface) of the cabinet 1 is disposed so as to overlap (or be in close contact with) the outer surface of a fixed partition 4 as an example of indoor equipment.

  The partition 4 includes a ground rail (lower frame) 8 and a wall panel 9 having an upward opening C-shape, and the wall panel 9 is attached to the support 10. Further, the partition 4 has a downward opening U-shaped rail (not shown) fixed to the ceiling surface, and the upper end of the support 10 is in tension with the top rail. Therefore, the partition 4 is held so as not to fall down.

  For example, the partition 4 is set to have a depth of 450 mm and a width in the frontage direction of 900 mm. On the other hand, the floor panels 2 are set to a square having a side length of about 500 mm, and the adjacent floor panels 2 abut on the side edges. The dimensions can be set arbitrarily.

(2) Structure of access floor The floor panel 2 of this embodiment is made of steel, and as shown in FIGS. 3 and 4, under the upper plate 11 having a square shape in plan view and the pair of left and right (or front and rear) It has a frame 12 and a large number of reinforcing frames 13 disposed so as to extend across a pair of lower frames 12, which are integrated by welding.

  Downward pieces 11a are formed on the four sides of the upper plate 11 except for the corner portion, and the downward pieces 11a of the adjacent floor panels 2 are set to overlap each other. Further, the four corner portions are notched in an arc shape in plan view, and groove portions 14 opened upward are formed in the notched portions in an arc shape, and four floor panels 2 adjacent to each other in the front, back, left, and right are formed. The connection ring 15 made of resin is fitted in the grooved portion 14. For this reason, the floor panel 2 is positioned in front, rear, left and right, and is laid accurately.

  The connection ring 15 has four claws 15a corresponding to the four grooved portions 14, and the connection ring 15 is held by the disc screw-like pusher 16 so that the connection ring 15 can not be pulled out. doing. The outer peripheral surface of the pusher 16 has a sawtooth shape in cross section and is engaged with the claw piece 15a.

  Adjusters 17 are disposed at the four corners of the floor panel 2. The adjuster 17 comprises a receiving member 18 penetrating the lower frame 12 from below and a bolt 19 screwed onto the receiving member 18 from below. The receiving member 18 is formed with a flange 20 for supporting the lower frame 12. It is done. The upper end of the receiving member 18 is fitted in a burring hole 21 formed in the upper plate 11. On the floor panel 2, a decorative board (floor board) 22 such as a cuppet is disposed. The decorative plate 22 is fixed to the upper plate 11 with an adhesive. It is needless to say that the adjuster 17 rests on the foundation floor (floor slab) 23 of the building.

(3) Structure of Base The base 7 of the present embodiment is of a height adjustable type, and as shown in FIGS. 5 and 6, a frame-shaped elevator 25 on which the cabinet body 5 is mounted and left and right supporting the same. The elevating body 25 is supported by the grounding body 26 via an adjuster bolt 27. The elevating body 25 has left and right side frames 28 and a front frame 29 and a rear frame 30 connecting them, and each of the frames 28, 29 and 30 has upper and lower horizontal pieces 31 and 32. The lower horizontal piece 31 is narrower than the upper horizontal piece 32.

  Front and rear auxiliary frames 33 are mounted and fixed to portions near the left and right ends of the front frame 29 and the rear frame 30. The auxiliary frame 33 is in the form of a U-shaped opening upward, and the front and rear ends thereof are fixed to the front frame 29 and the rear frame 30 by welding or the like.

  The ground body 26 is disposed below the auxiliary frame 33, and the adjuster bolt 27 fixed to the ground body 26 is inserted into the auxiliary frame 33 from below, and the nut 34 engaged with the adjuster bolt 27 makes the auxiliary frame 33 The (lifting body 25) is supported so as to be adjustable in height.

  The ground body 26 is formed in an inverted M shape having left and right ground portions 26a, and an adjuster bolt 27 is fixed to the left and right middle portions. However, the ground body 26 can select an arbitrary shape. For example, the adjuster bolt 27 may be fixed to the upper surface of the U-shaped opening upward. Further, it is also possible to fix the nut 34 to the auxiliary frame 33 and rotate the adjuster bolt 27 to adjust the height of the elevating body 25.

  Furthermore, the base 7 does not have to be of a height adjustable type, and may be of a type in which a grounding body for reinforcement and combined use is fixed to the front and rear frames 29 and 30. In addition, a structure having a lower plate which spreads over the entire lower surface of the base 7 is also employable.

(4). Overturn preventing structure The overturn preventing structure is shown in FIG. 7 and FIG. 6 (B). That is, first, the base 7 is placed at a predetermined position and the height is adjusted, and then the grounding body 26 of the base 7 is fixed to the floor panel 2 using a self-piercing screw such as a drill screw 36. . The drill screw 36 is screwed into the upper plate 11 of the floor panel 2 through the decorative plate 22.

  The drill screw 36 may be screwed into the overlapping portion of the upper plate 11 and the reinforcing frame 13. Alternatively, it may be screwed into the overlapping portion of the upper plate 11 and the lower frame 12 or the overlapping portion of the upper plate 11, the reinforcing frame 13 and the lower frame 12.

  As shown in FIG. 1, the partition 4 is not located at the boundary portion 37 of the row of floor panels 2, and is disposed in the middle of the front and back of the floor panels 2 aligned in the longitudinal direction of the partition 4. It is done. For this reason, the group of floor panels 2 is held down from above by the partition 4, and the cabinet 1 spans both the floor panel 2 held down and held by the partition 4 and the floor panel 2 separated from the partition 4. It is mounted on the floor panel 2 and fixed to the floor panels 2 with drill screws 36. The number of drill screws 36 to be driven may be appropriately set in consideration of the weight of the articles stored in the cabinet 1 and the like.

  In the event of an earthquake, the cabinet 1 swings in the front-rear direction and tries to fall forward as shown by the outlined arrows in FIG. And since the floor panel 2 is fixed to the base 7, when the cabinet 1 tries to fall forward, the floor panel 2 tries to get up. However, since the floor panel 2 to which the back portion of the base 7 is fixed is held by the partition 4 so as not to rise up, the cabinet 1 is prevented from falling forward. Accordingly, it is possible to prevent the cabinet 1 from tipping over (forward tipping).

  That is, the floor panel 2 and the partition 4 are used to prevent the cabinet 1 from falling. When the drill screw 36 is driven into a plurality of the upper plate 11, the reinforcing frame 13 and the lower frame 12, the fastening strength is significantly increased, and the overturn preventing function can also be greatly improved. The cabinet body 5 may be simply fitted into the elevating body 25 of the base 7 from above, but if it is fixed to the elevating body 25 with a screw or the like, the fall prevention function can be made more reliable.

(5) Second to Fifth Embodiments Next, second to fifth embodiments shown in FIGS. In the second embodiment shown in FIG. 8, the partition 4 is located at the edge of the floor panel 2, and the cabinet 1 rests only on the floor panel 2 held and held by the partition 4. However, since the floor panel 2 on which the cabinet 1 is mounted is held down by the partition 4, the cabinet 1 is prevented from being overturned.

  In the third embodiment shown in FIG. 9, the partition 4 is located on one side across the boundary portion 37 of the row of floor panels 2, and the cabinet 1 is located on the other side across the boundary portion 37. ing. For this reason, the floor panel 2 on which the cabinet 1 is placed is not held and held by the partition 4.

  Therefore, the plate 38 is disposed below the base 7, and the upright piece 38a provided on the plate 38 is fixed to the ground rail 8 of the partition 4 with a screw 39 such as a drill screw or tapping screw. The upper plate 11 of the panel 2 is fixed (co-fastened) with a drill screw 36. Accordingly, the floor panel 2 on which the cabinet 1 is mounted is held down by the partition 4 via the plate 38, thereby preventing the cabinet 1 from tipping over.

  When the cabinet 1 is placed close to the wall of the building, the standing pieces 38a of the plate 38 may be anchored to the wall of the building. The plate 38 can also be applied to the first embodiment and the second embodiment.

  In the fourth embodiment shown in FIG. 10A, the partition 4 is located directly above the boundary 37 of the row of floor panels 2. Therefore, the group of floor panels 2 on both sides of the boundary portion 37 is held down by the partition 4 and held.

  Therefore, the cabinet 1 arranged back to back with the partition 4 is prevented from overturning by fixing its base 7 to the floor panel 2. However, in the fourth embodiment, the flat plate 38 is further divided into the base 7 and the partition 4 and floor panel 2 are arranged. For this reason, the pressing and holding function of the floor panel 2 by the partition 4 is ensured. When arranging the cabinet 1 on both sides of the partition 4, when the plate 38 is arranged to spread on both sides of the partition 4, the floor panels 2 located on both sides across the boundary portion 37 are integrated via the plate 38 Therefore, it can be said that the fall prevention function of the cabinet 1 can be further improved.

  In the fifth embodiment shown in FIG. 10B, the partitions 1 are not used, the cabinets 1 are arranged back to back, and the front and rear cabinets 1 are mounted on a single plate 38. Then, the bases 7 of both cabinets 1 are fastened to the plate 38 and the floor panel 2 with drill screws 36 respectively.

  In this embodiment, the front and rear cabinets 1 are integrated via a plate, and the bottom area is in the same state as the size of twice the front-rear width of the floor panel 2. Therefore, high fall prevention function is exhibited also in this case. Different types of furniture may be placed back to back.

(6) Sixth Embodiment The present invention is also applicable to a fall prevention system for wooden furniture. An example thereof will be described with reference to the drawings following FIG. FIG. 11 shows a state in which the wooden cabinet 1 'provided with the glass cupboard 40 is disposed back to back with the partition 4, and the cabinet 1' comprises the partition 4 and the floor panel 2 as in the previous embodiment. It is used to prevent falls.

  In FIG. 11, the cabinet 1 'on the left side is formed with a storage portion provided with a wooden pivoting door 41 below the glass cupboard 40, and in the cabinet 1' on the right side, below the glass cupboard 40. A plurality of drawers 42 are mounted. The specific structure of the cabinet 1 'can be set arbitrarily.

  As clearly shown in FIG. 12, the cabinet 1 ′ has left and right side plates 43, back plates 44 and bottom plates 45. The bottom plate 45 is positioned to a certain extent above the lower ends of the side plates 43 and the back plate 44, and the lower weir plate 46 is disposed below the front end of the bottom plate 45. For this reason, at the lower end portion of the cabinet 1 ', a downward opening lower space 47 surrounded by the side plate 43, the back plate 44, the bottom plate 45, and the lower cover plate 46 is formed.

  In the present embodiment, a plate 38 is used as the overturn preventing means, and an upright piece 38 a fixed to the ground rail 8 of the partition 4 with a screw 39 is formed at the rear end of the plate 38. The plate 38 is sized to receive the entire cabinet 1 '.

  A hat-shaped auxiliary member 49 having a top plate 49a and an outwardly directed lower horizontal piece 49b is fixed to the plate 38 as a means for connecting the plate 38 and the cabinet 1 '. A screw 50 penetrating the bottom plate 45 of the cabinet 1 'is screwed into the face plate 49a.

  The front and rear lower horizontal piece 49b of the auxiliary member 49 is fixed to the plate 38 by welding or the like, and the lower cover plate 46 and the back plate 44 of the cabinet 1 'are mounted on the lower horizontal piece 49b. The front and rear end portions of the side plate 43 of the cabinet 1 'are also mounted on the front and rear lower horizontal pieces 49b of the auxiliary member 49. Therefore, a gap is left between the left and right side plates 43 and the plate 38 between the front and rear lower horizontal pieces 49 b of the auxiliary member 49.

  13B, a spacer 49c having the same thickness as that of the auxiliary member 49 is fixed to a portion of the plate 38 between the front and rear lower horizontal pieces 49b of the auxiliary member 49, as shown by the alternate long and short dash line in FIG. 43 may be placed on the spacer 49c. By providing the spacer 49c in this manner, the integrity of the cabinet 1 'and the plate 38 can be improved. A portion of the plate 38 overlapping the lower horizontal piece 49 b of the auxiliary member 49 is fixed to the floor panel 2 by a drill screw 36.

  The construction procedure of this embodiment is the same as before, and the plate 38 to which the auxiliary member 49 is fixed is set at a predetermined position, and the plate 38 is fixed to the ground rail 8 of the partition 4 with screws. The process of fixing the floor panel 2 with the drill screw 36, setting the cabinet 1 'on the plate 38 from above and setting in a predetermined posture, screwing the screw 50 inserted in the bottom plate 45 into the top plate 49a of the auxiliary member 49. It will go through.

  The upper surface plate 49a of the auxiliary member 49 may be provided in advance with a female screw hole (or a nut) in which the screw 50 is screwed, or may be drilled in the upper surface plate 49a using a screw screw or tapping screw as the screw 50. Tapping may be performed on site. The lower hole of the bottom plate 45 is preferably opened in advance.

  In the present embodiment, since the plate 38 is fixed to the ground rail 8 of the partition 4, even if the cabinet 1 ′ is placed on the floor panel 2 not pressed by the partition 4, the cabinet 1 ′ using the partition 4 Fall can be prevented. When the floor panel 2 on which the partition 4 is placed is held down by the partition 4, the overturn preventing function of the cabinet 1 'is further enhanced.

  When the left-right width of the plate 38 is set to the same dimension as the left-right width of the cabinet 1 'as in the embodiment, when the cabinet 1' is arranged side by side, the plates 38 are arranged side by side without a gap. The cabinets 1 'can be arranged side by side with no gap.

Seventh Embodiment FIG. 14 shows a seventh embodiment. This embodiment is a modification of the sixth embodiment, and the angle reinforcing member 51 fastened to the side plate 43 and the bottom plate 45 with a screw or the like is fixed to the cabinet 1 'with the sixth embodiment as a basic structure. The upper horizontal piece and the bottom plate 45 of the reinforcing member 51 are fastened together with the screw 50 to the top plate 49 a of the auxiliary member 49.

  Since the wooden cabinet 1 'is lower in strength than the steel cabinet 1', the connection between the bottom plate 45 and the side plate 43 and the back plate 44 is broken during an earthquake, causing the cabinet 1 'to be damaged or deformed. If the reinforcing member 51 is provided as in this embodiment, the cabinet 1 'is reinforced, so that the cabinet 1' can be broken or deformed in the event of an earthquake. .

  In addition to or in place of connecting the left and right side plates 43 and the bottom plate 45 with the reinforcing member 51, as shown by the alternate long and short dash line in (A), the bottom plate 45 and the back plate 44 (and / or the bottom plate 45 and the lower plate The reinforcing member 51 may be connected to the plate 46). In addition, a downward opening box-like reinforcing frame material which is closely fitted to the inner periphery of the lower space 47 is fixed to the bottom plate 45, the side plate 43, the back plate 44 and the lower cover plate 46, and this box-like reinforcing frame material is interposed. It is also possible to fix the bottom plate 45 to the auxiliary member 49. In this case, the fall prevention measures of the cabinet 1 'will be perfect.

  Further, in both the sixth embodiment and the seventh embodiment, the auxiliary members 49 are formed in a box shape opened downward as a whole by bending downward pieces on both left and right ends of the upper surface plate 49a in the auxiliary members 49. In such a configuration, the strength of the auxiliary member 49 can be greatly improved, so that the overturn preventing function can be further improved.

(8) Eighth to eleventh embodiments and others FIG. 15 shows a modification of the plate 38 applied to the wooden cabinet 1 '. Among them, in the eighth embodiment shown in (A), the lower horizontal piece 49 b of the auxiliary member 49 is formed in the front and rear direction. In this case, since only the plate 38 is fixed to the floor panel 2, the operation of fixing the plate 38 can be reduced.

  In the ninth embodiment shown in (B), the auxiliary member 49 is formed by cutting and raising the plate 38. In this example, if a flat plate is fixed to the upper surface of the upper surface plate 49a by welding or the like, the rigidity can be remarkably improved. In (A) and (B), since there is a certain distance between the upper surface plate 49a and the side plate 43, the left and right side portions of the plate 38 can be fixed to the floor panel 2 at any front and rear portions.

  In the tenth embodiment shown in (C), the stopper piece 52 overlapping the inner peripheral surface of the lower space 47 in the cabinet 1 'is cut and raised on the plate 38. In this embodiment, the lower end portion of the cabinet 1 'is firmly fitted in the group of the stopper pieces 52 on the plate 38 so as not to shift sideways, thereby preventing overturning. When the stopper pieces 52 are connected by a horizontal upper plate, bending and deformation of the stopper pieces 52 can be prevented, so that the overturn preventing function can be improved, and the upper plate and the bottom plate 45 can be fixed by screws.

  Also in the eleventh embodiment shown in (D), the stopper pieces 52 are provided on the plate 38, but the front end and the left and right stopper pieces 52 are formed by bending, and the adjacent stopper pieces 52 are integrated by welding There is. Therefore, the stopper piece 52 exerts high resistance to bending. Therefore, the fall prevention function of the cabinet 1 'is significantly improved. Further, in this embodiment, since the plate 38 is grounded to the floor in a large area, the fastening position to the floor panel 2 and the fastening number can be arbitrarily set, which is excellent in flexibility.

  In the case of FIGS. 15 (C) and 15 (D), it is possible to provide an adjust bolt at the four corners of the cabinet 1 'and place it on the corner of the plate 38. In the case of providing an adjustment bolt, the bottom plate 45 can not be fixed to the auxiliary member 49, but in (C) and (D), the lower end portion of the cabinet 1 'is fitted nondisplaceably to the group of stopper pieces 52. Therefore, it becomes possible to adjust the height while preventing the fall.

  The present invention can be variously embodied in addition to the above embodiments. For example, the floor panel 2 does not necessarily have to be made of metal plate (made of steel), and can be applied to floor panels made of caiscal or concrete.
