Description

[Technical Field]

[0001] SUMMARY OF THE INVENTION An embodiment of the present invention relates to an aperture revealing member. [Background technology]

[0002] Traditionally, double flooring in offices and machine rooms allows wiring and air conditioning equipment to be stored underneath the floor. Not having exposed wiring on the floor increases the flexibility of indoor layouts and allows for functional facility operation. This double floor structure is called a free access floor. When installing wiring or equipment within the free access floor, the floor panels must be partially removed, and the height of the free access floor can sometimes be 300 mm or more. A fence is installed over the opening above the floor when the panel is removed to warn people.

[0003] A common method of separating areas is to install pylons or cones around openings to clearly indicate the area and prevent workers or third parties from accidentally entering. However, in small server rooms, installing pylons can make it difficult to secure sufficient work space and passageways. Also, since the panels to be removed are not necessarily regular, depending on the shape of the opening, separating areas may require many pylons or cones, which can significantly reduce work efficiency.

[0008] The opening designating member 10 of this embodiment will be described below with reference to the drawings. The configuration of the embodiment described below, as well as the actions and results (effects) brought about by said configuration, are merely examples and are not limited to the following description. Note that in this specification, ordinal numbers are used only to distinguish between parts and components, and do not indicate order or priority.

[0009] Fig. 1 is a schematic diagram of an opening designating member 10 of this embodiment. As shown in Fig. 1, the entire opening designating member 100 includes, for example, a free access floor 2, a space below the free access floor 2, an opening 1 formed in the free access floor 2, an opening designating member 10, and a surrounding material (attention-calling tape) 3 for surrounding the opening 1 that is provided across multiple opening designating members 10.

[0010] The free access floor 2 is formed, for example, by installing multiple floor panels. The space below the free access floor 2 is a double bottom, with a wiring space for wiring and the like. The free access floor 2 is supported by multiple supports placed on the bottom surface of the underfloor space. The free access floor 2 may also be an outdoor road surface.

[0011] The opening 1 provided in the free access floor 2 is, for example, an opening 1 that allows access to the space below by removing at least one panel of the free access floor 2 in order to perform work in the space below. The opening 1 is formed by floor panels that form at least a part of the outline of the opening formed in the free access floor 2. Multiple panels of the opening 1 are removed depending on the work range. The range of removal also changes depending on the work. In the case of a road surface, the opening 1 may be an opening 1 where a manhole has been removed.

[0012] The opening designating members 10 have, for example, a fixed part 11 that is fixed to the free access floor 2, and a support 12 that is connected to the fixed part 11 and extends upward from the fixed part 11. The opening designating members 10 are connected to each other by a warning tape 3.

[0013] The warning tape 3 may be, for example, a string-like member, an expandable rod-like member, or a plastic chain, in addition to tape. The warning tape 3 may also be a string-like member that is integral with the opening specifying member 10 and extends expandably from the opening specifying member 10.

[0014] The fixed part 11 has two support parts. The support parts support the fixed part 11 by sandwiching the free access floor 2 from above and below. In other words, the free access floor 2 is fixed by sandwiching the upper and lower surfaces of the free access floor 2. The fixed part 11 has support parts located on both sides of the support column 12. The support parts are spaced apart from each other, spaced apart from each other and further outwards than the width of the support column 12, with the support column 12 as the center.

[0015] As a result, the opening specifying member 10 can be fixed by suction to the free access floor 2 using the fixing part 30, and therefore can be fixed without increasing the space required for the fixing part 30. This reduces the installation space and ensures that the working space on the free access floor 2 is secured.

[0016] Furthermore, because the support parts are located on both sides of the support pillars 12, it is possible to prevent the support parts from interfering with the supports that support the underside of the free access floor 2 in the space below. Also, the support parts can each rotate around a fulcrum relative to the support pillars 12. This makes it easy to change the clamping direction of the support parts, thereby avoiding interference.

[0017] The support 12 is extendable and retractable, for example, in the direction of the fixed part 11. That is, when the support 12 is folded for transport, and when the fixed part 11 is fixed, the support 12 can be extended upward. This allows the opening specifying member 10 to be sized for easy portability. The support 12 may also be rotatable around a boundary line 17 in the height direction.

[0018] Fig. 2 is a diagram showing the fixing part 11 of the opening revealing member 10 of this embodiment. As shown in Fig. 2, the opening revealing member 10 has the fixing part 11 and a support 12 connected upward from the fixing part 11.

[0019] The fixing part 11 has, for example, a base part 13 that is integral with the support pillar 12, and support parts 14a and 14b that are attached to the base part 13. The base part 13 is a substantially flat plate that abuts against the upper surface of the free access floor 2. The support parts 14a and 14b are located on either side of the base part 13, sandwiching the support pillar 12 between them. Because the base part 13 abuts against the upper surface, it can be fixed by increasing the area that comes into contact with the floorboard.

[0020] The support portions 14a and 14b are rotatable about fulcrums 16a and 16b attached to the base portion 13. The support portions 14a and 14b are shaped, for example, like clips, so that they can clamp from above and below. Specifically, the base portion 13 abuts against the free access floor 2 from above, and the surfaces of the support portions 14a and 14b opposite the base portion 13 abut against the free access floor 2 from the space below, thereby clamping the free access floor 2. Furthermore, rubber sheets 15a and 15b may be attached to the surface opposite the base portion 13. In this way, even if the bottom surface of the free access floor 2 has an uneven shape, the rubber sheets 15a and 15b can make it less slippery and easier to secure.

[0021] Fig. 3 is a diagram showing the support 12 of the opening specifying member 10 of this embodiment. Fig. 3(a) shows an enlarged view of the slit 18 provided in the upper part of the support 12. Fig. 3(b) shows the slit 18 of the support 12 in plan view. As shown in Fig. 3, the slit 18 is provided in the upper part of the support 12 of the opening specifying member 10. The support 12 may be rotatable in the height direction around a boundary line 17.

[0022] The slit 18 is, for example, a cross-shaped slit as shown in FIG. 3(b). By attaching the warning tape 3 to the slit 18, the direction of the warning tape 3 can be changed. Furthermore, by rotating the warning tape 3 around the boundary line 17, the direction of the warning tape 3 can be finely adjusted. Although the cross-shaped slit 18 is used as an example, it may also be L-shaped. Even if the slit 18 is L-shaped, the direction of the warning tape 3 can be finely adjusted by rotating the warning tape 3 around the boundary line 17.

[0023] Fig. 4 is a diagram showing the fixing part 11 of the opening-identifying member 10 of the present embodiment 2. As shown in Fig. 4, the opening-identifying member 10 has the fixing part 11 and a support 12 connected upward from the fixing part 11.

[0024] The fixed portion 11 has, for example, a base portion 13 that is integral with the support pillar 12, and support portions 20a and 20b. The base portion 13 is a substantially flat plate that abuts against the upper surface of the free access floor 2. The support portions 20a and 20b are attached at positions outside and away from the support pillar 12 that is fixed to the base portion 13. In other words, the support portions 20a and 20b are located on both sides of the base portion 13, with the support pillar 12 in between.

[0025] The support sections 20a and 20b are rotatable about fulcrums 22a and 22b attached to the base section 13. The support sections 20a and 20b are clamped from above and below, for example, in the shape of a U, and the clamping width of the U or U shape can be adjusted by tightening the bolts 21a and 21b. Specifically, the base section 13 abuts against the free access floor 2 from above, and by tightening the bolts 21a and 21b, the surfaces of the support sections 20a and 20b that abut against the underside of the floorboards of the free access floor 2 narrow toward the upper surface of the floorboards, i.e., toward the base section 13, thereby abutting from the space below the free access floor 2 and clamping the free access floor 2. This allows the free access floor 2 to be clamped firmly. Furthermore, the clamping amount of the free access floor 2 can be adjusted depending on the amount the bolts 21a and 21b are tightened.

[0026] Furthermore, rubber sheets 23a and 23b may be attached to the surface opposite to base portion 13. This makes it easier to fix the free access floor 2 with rubber sheets 23a and 23b even if the underside of the free access floor 2 has an uneven shape.

[0027] Fig. 5 is a plan view of the opening specification member 10 of this embodiment. As shown in Fig. 5, for example, the free access floor 2 is formed by installing floor panels in a 5 x 10 grid. Here, in order to perform work in the underfloor space, 12 panels of the free access floor 2 are removed, forming an L-shaped opening 1.

[0028] The opening designating members 10 are arranged, for example, in seven locations so as to surround the outer periphery of the opening 1. That is, the opening designating members 10 are provided on the floorboards that form the outline of the opening. The fixing parts 11 of the opening designating members 10 are fixed to the free access floor 2 by clamping them from the upper and lower surfaces of the free access floor 2, i.e., from above and from the space under the floor. The height of the opening designating members 10 can be adjusted by extending the support posts 12 while the opening designating members 10 are fixed.

[0029] The warning tape 3 is attached across the support posts 12. The direction of the warning tape 3 may be changed by the slits 18 in the support posts 12. By wrapping the warning tape 3 around multiple support posts 12, the opening 1 is surrounded by the warning tape 3. In other words, it is provided along the outline of the opening. This can be similarly applied to the second embodiment.

[0030] Fig. 6 is a schematic diagram of the opening designating member 10 of the present embodiment 3. As shown in Fig. 6, similar to Fig. 1, for example, the opening designating member 10 includes a free access floor 2, an opening 1, an opening designating member 10, and a warning tape 3.

[0031] The opening revealing member 10 has, for example, a fixed part 30 that is fixed to the free access floor 2 and a support 12 that is connected to the fixed part 30 and extends upward from the fixed part 30.

[0032] The fixing part 30 is fixed by adsorption to the free access floor 2. As a result, the opening designating member 10 can be fixed by adsorption to the upper surface of the free access floor 2 using the fixing part 30, and therefore can be fixed without increasing the space required for the fixing part 30. This reduces the installation space and ensures working space for the free access floor 2. It is also possible to prevent the fixing part 30 from interfering with the supports that support the free access floor 2 from below. The opening designating member 10 is attached to a floor plate that forms at least part of the outline of the opening in the free access floor 2.

[0033] Fig. 7 is a diagram showing the fixing part 30 of the opening-identifying member 10 of the present embodiment 3. As shown in Fig. 7, the opening-identifying member 10 has the fixing part 30 and a support 12 connected upward from the fixing part 30.

[0034] The fixed part 30 may have, for example, a circular bottom surface that tapers toward the upper support 12. The fixed part 30 has a support part 31 on the bottom surface thereof, a movable iron plate 32 provided on the support part 31, a detachment lever 34 that moves the movable iron plate 32 radially outward and inward of the fixed part 30, and a magnet 33 provided above the movable iron plate 32.

[0035] The detachment lever 34 is connected to the support part 31 by, for example, a connecting rod. The detachment lever 34 can move to the bottom side (downward) and the support side (upward). The movable iron plate 32 is divided into two parts, and when the detachment lever 34 is moved downward, the movable iron plates 32 move in a direction in which they come into contact with each other (inward). When the detachment lever 34 is moved upward, the movable iron plates 32 move in a direction in which they move away from each other (outward).

[0036] If the free access floor 2 contains a metal material, moving the detachment lever 34 downward will fix the free access floor 2 in a state where the adhesive force between the movable iron plate 32 and the magnet 33 is strongest. On the other hand, moving the detachment lever 34 upward will weaken the adhesive force between the movable iron plate 32 and the magnet 33 and the free access floor 2. In other words, when the support part 31 is brought into contact with the free access floor 2 and the detachment lever 34 is moved downward, adhesion is achieved. Furthermore, the support part 31 can be removed from the free access floor 2 by moving the detachment lever 34 upward.

[0037] Although the operation of the detachment lever 34 has been described as moving it up and down, it may also be moved left and right or rotated.

[0038] Fig. 8 is a diagram showing the fixing part 40 of the opening-identifying member 10 of the present embodiment 4. As shown in Fig. 8, the opening-identifying member 10 has the fixing part 40 and the support 12 connected upward from the fixing part 40.

[0039] The fixing part 40 may have, for example, a circular bottom surface that tapers toward the upper support 12. The fixing part 40 has a support part 41 with a suction cup on the bottom surface thereof, and a detachment lever 42 that allows the support part 41 to be detached.

[0040] The support part 41 is, for example, a suction cup, and can be fixed by being pressed against the upper surface of the free access floor 2. When removing the support part 41 from the free access floor 2, air can be taken into the support part 41 by operating the detachment lever 42, and then the support part 41 can be removed.

[0041] Fig. 9 is a plan view of the opening designating member 10 of the third embodiment. As shown in Fig. 5, for example, a free access floor 2 is installed and the opening 1 is formed in an L-shape. That is, the outline of the opening is formed in an L-shape by the floorboards. The opening designating members 10 are arranged so as to surround the outline around the opening 1. A warning tape 3 is wrapped around the multiple opening designating members 10 so as to connect them.

[0042] The opening designating members 10 are arranged, for example, at seven locations surrounding the outer periphery of the opening 1. The fixing parts 30 of the opening designating members 10 are fixed by being attached to the free access floor 2. The height of the opening designating members 10 can be adjusted by extending the support posts 12 while the opening designating members 10 are fixed. This can be similarly applied to the fourth embodiment.

[0043] Fig. 10 is a diagram showing the fixing portion 11 of the opening-declaring member 10 of the fifth embodiment. Fig. 10 shows an example in which the support portions 50a, 50b attached to the base portion 13 are magnets 33 as shown in Fig. 7. However, they may also be suction cups as shown in Fig. 8.

[0044] As shown in FIG. 10, the opening-declaring member 10 has a fixed portion 11 and a support 12 connected upward from the fixed portion 11.

[0045] The fixed portion 11 has, for example, a base portion 13 that is integral with the support pillar 12, support portions 50a and 50b, and second support portions 51a and 51b. The base portion 13 is a substantially flat plate that abuts against the free access floor 2 from above. The support portions 50a and 50b are provided at positions outside and away from the support pillar 12 that is fixed to the base portion 13. In other words, the support portions 50a and 50b are located on both sides of the base portion 13, with the support pillar 12 in between.

[0046] The supports 50a and 50b are, for example, magnets. If the free access floor 2 includes a metal material, the supports 50a and 50b can be attracted by the magnets provided on the two supports 50a and 50b.

[0047] The support portions 50a and 50b are, for example, suction cups, and can be attached to the free access floor 2 by suction cups provided on the two support portions 50a and 50b.

[0048] Next, the second support portions 51a and 51b are connected to the base portion 13 and configured to sandwich the free access floor 2 from above and below. Alternatively, the second support portions 51a and 51b may be clips.

[0049] This allows the support parts 50a and 50b to adhere to the free access floor 2 at two points, and furthermore, by sandwiching the support part between the second support parts 51a and 51b, the support part can be fixed more firmly.

[0050] Rubber sheets 52a and 52b may be attached to the bottom surfaces of the second support portions 51a and 51b, thereby enabling more secure fixation by the rubber sheets 52a and 52b in addition to the adhesion by the support portions 50a and 50b and the sandwiching by the second support portions 51a and 51b.

[0051] As a modification, a configuration that does not include second support portions 51a and 51b, which is different from the configuration of base portion 13, support portions 50a and 50b, and second support portions 51a and 51b shown in Fig. 10, is taken as an example. That is, a configuration that includes base portion 13 and support portions 50a and 50b, too. In this case, adsorption is possible using support portions 50a and 50b in two locations, and the shape of fixed portion 11 can be simplified because second support portions 51a and 51b are not included.

[0052] As a second modification, a fixing part 30 such as that shown in Fig. 7 may be provided with one of the clips shown in Fig. 2. This allows fixing to the free access floor 2 with one large clip. Alternatively, a fixing part 30 shown in Fig. 7 may be provided with one of the U-shaped support parts shown in Fig. 4. This allows fixing to the free access floor 2 with the U-shaped support part.

[0053] As explained above, the opening indication member 10 of this embodiment is provided on a free access floor as an example, but it may also be provided to surround the periphery of an opening provided on the floor of a factory, or to surround the periphery of an opening formed in the ground outdoors after a manhole has been removed.

[0054] As described above, the opening designating member 10 of this embodiment is an opening designating member that is provided on a floorboard that forms at least part of the outline of an opening to be formed in a free access floor, and has a fixed part that is fixed to the floorboard at at least two points, and a support that is connected to the fixed part and supports a fencing material for surrounding the opening, and the fixed part has support parts located on both sides of the support.

[0055] As a result, the fixing portion of the opening specifying member 10 is fixed to the free access floor, and therefore can be fixed without increasing the installation space around the opening.

[0056] Moreover, the fixing portion of the opening revealing member 10 of this embodiment has a base portion that abuts against the upper surface of the floorboard, and a support portion that abuts against the lower surface of the floorboard.

[0057] As a result, the fixing portion of the opening revealing member 10 can increase the surface area that comes into contact with the upper surface by the base portion, and can be fixed more stably. In addition, the support portion can fix the fixing portion firmly.

[0058] Furthermore, the support parts of the opening-declaring member 10 of this embodiment are fixed by sandwiching the upper and lower surfaces of the floorboard.

[0059] As a result, the support parts of the opening-declaring member 10 can be fixed in the vertical direction by sandwiching the upper and lower surfaces. Furthermore, since the support parts are spaced apart on the outside, interference with support pieces in the space below can be avoided.

[0060] Furthermore, the support portion of the opening-declaring member 10 of this embodiment has a bolt that can adjust the amount of clamping of the upper surface.

[0061] This allows the support part of the opening-declaring member 10 to adjust the amount of clamping of the upper surface, so that it can be fixed more firmly.

[0062] In addition, the opening designating member 10 of this embodiment is an opening designating member that is provided on a floorboard that forms at least part of the outline of an opening to be formed in a free access floor, and has a fixing part that is fixed by adsorption to the upper surface of the floorboard, and a support that is connected to the fixing part and supports an enclosure material for surrounding the periphery of the opening.

[0063] As a result, the fixing portion of the opening revealing member 10 is fixed by being sucked onto the upper surface, and therefore can be fixed without increasing the arrangement space around the opening.

[0064] Furthermore, the floor plate of the opening-declaring member 10 of this embodiment contains a metal material, and the fixing portion contains a magnetic material, and is fixed by being attracted to the upper surface of the floor plate.

[0065] This allows the opening-depicting member 10 to be fixed by adhesion between the upper surface containing a metal material and the fixing portion.

[0066] Furthermore, the fixing portion of the opening revealing member 10 of this embodiment is fixed by sandwiching the upper and lower surfaces of the floorboard.

[0067] As a result, the fixing parts of the opening revealing member 10 can be fixed more firmly in the vertical direction by sandwiching the upper and lower surfaces.

[0068] Furthermore, the support posts of the opening-declaring member 10 of this embodiment are extendable and retractable toward the fixed part.

[0069] This allows the support posts of the opening revealing member 10 to be extendable and therefore easy to carry.

[0070] In addition, the upper part of the support post of the opening revealing member 10 of this embodiment is provided with a slit that changes the extension direction of the surrounding material.

[0071] This allows the support posts of the opening specifying member 10 to freely change the direction in which they surround the warning tape or the like.

[0072] Furthermore, a rubber sheet is attached to the underside of the fixing portion of the opening specifying member 10 of this embodiment.

[0073] As a result, even if the underside of the free access floor 2 has an uneven shape, the rubber sheet makes it less slippery, allowing it to be firmly fixed.

[0074] Although several embodiments of the present invention have been described above, these embodiments are presented as examples and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included within the scope and spirit of the invention, as well as within the scope of the invention and its equivalents as defined in the claims.
