DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor panel (for building a free access floor) in which an opening formed on the inner peripheral surface of a paragraph flange with respect to the upper surface of the panel is provided on the side.
The present invention relates to a closing lid for closing an opening of a floor panel by aligning an upper surface of a panel with an upper surface of a lid and mounting an outer peripheral flange continuous from the upper surface of the lid on the paragraph flange.

[0002]

2. Description of the Related Art A floor panel for constructing a free access floor is disposed directly on a foundation floor or via support legs so that power lines and communication lines stretched between the floor panel and the foundation floor can be appropriately drawn out. Flooring, and realizes free wiring especially in offices where OA is used. A general floor panel has an opening at a side portion, and is used for distributing an outlet box or drawing out a communication line or the like at a number of openings laid all over the foundation floor. The openings are individually closed with closing lids having communication holes, and communication lines and the like are drawn from necessary communication holes.However, unnecessary openings are reduced, and the height of the panel and the step Unused ports are usually closed to minimize certain parts.

For example, Japanese Patent Application Laid-Open No. 6-165351 discloses an example in which a communication port can be formed as necessary by appropriately cutting a communication port forming portion integrally formed with a closing lid. This example is partitioned by forming a guide portion thinner than the thickness of the lid upper surface on the front and back surfaces of the lid upper surface of the closing lid,
The passage opening forming portion is punched upward from the closing lid with pliers or the like and opened to open a communication line or the like.
The punched-through hole forming part cannot be integrated with the closing lid again, but the guiding part provided on the back of the lid upper surface is formed slightly shifted inward from that provided on the front surface of the lid, and the closing lid is formed. The guide groove on the top and the back of the lid after separating the passage opening forming portion from the slope forms a slope so that the passage opening forming portion can be placed on the slope to close the passage opening. It is.

[0004]

The above-mentioned example (JP-A-6-16535)
No. 1) has the following problems in drawing out communication lines and the like, which is the main purpose of the communication port. First, there is a problem that burrs formed along the guide portion by punching out the communication hole forming portion may damage the drawn communication line and the like.
As described above, in the illustrated closing lid, the passage opening forming portion is placed along the guide portion so that the passage opening can be closed, but in fact, the burr formed in the guide portion is an obstacle. become,
The upper surface of the panel or the lid of the closing lid is not aligned with the upper surface of the lid of the communication hole forming portion. In order to secure the load resistance of the guide portion before the passage opening portion is separated, the guide portion cannot be made too thin. As a result, the punching operation of the passage opening portion requires a considerable force. In order to solve the above-mentioned problem of burrs, it is only necessary to apply a file or the like to the guide portion after the passage hole forming portion is separated as deburring, but if the deburring work is added to the punching work as described, the passage hole is removed. It takes too much time and effort to create one, which is not preferable.

[0005] In addition, there is a possibility that the punched-out passage-portion forming part may be lost, and when the unused passageway-porting part is closed again, whether the corresponding passageway-forming part is properly stored. It is questionable. Even if it is stored and the communication port opening can be closed at the communication port, both are not engaged or fitted, and the communication port forming section is simply placed on the communication port. Because of this, it is possible that the line opening forming part may easily come off from the line opening due to the slight load applied to the placed line opening forming part or the vibration transmitted from the floor panel or blocking lid. possible.

In addition, a communication line or the like drawn out from a communication hole may be damaged by contacting a paragraph flange of a floor panel exposed from the communication hole, or the paragraph flange may form a step with respect to a panel upper surface or a lid upper surface. It is inconvenient. This is not limited to the case where unwired communication lines etc. are drawn out from the line openings, and the case where the line openings to be drawn out without disconnecting the communication lines etc. connected to the electronic equipment etc. are assumed. Is formed as an opening that is open continuously to the periphery of the lid upper surface of the closing lid. It is also conceivable to take measures such as deburring or rounding the paragraph flange, but it is impossible to strictly eliminate burrs from the metal floor panel, and it is preferable to introduce new processing costs such as rounding Absent. Processing of the paragraph flange is practically difficult with a concrete floor panel. Therefore, on the premise that the opening ratio as a floor panel is suppressed as much as possible, the handling of the passage openings on the actual operation side is made simple and practical enough.
It was decided to examine a closing port including a communication port and a member capable of arbitrarily closing the communication port.

[0007]

As a result of the study, the present inventors have developed a method in which the upper surface of the panel is aligned with the upper surface of the lid with respect to a floor panel in which an opening formed on the inner peripheral surface with a paragraph flange for the upper surface of the panel is provided on the side. A lid body that covers the opening of the floor panel by placing an outer peripheral flange continuous from the upper surface of the lid on the paragraph flange, wherein the closing lid has a notch inwardly from the outer peripheral flange of the section corresponding to the paragraph flange placement. And a substantially L-shaped lid member in a side view formed by a cover surface and a passage opening forming surface to be attached to the notch, wherein the cover surface has a shape substantially equal to the notch, and the passage opening forming surface is provided in the notch. When the lid member is put in the notch and the cover member is attached to the notch, the closing surface forms a part of the top surface of the cover and closes the notch, and the communication hole forming surface is less than the notch but covers at least the paragraph flange exposed from the notch. Shaped, notch in closed surface When the cover member is inserted and the cover member is mounted in this notch, the passage opening forming surface constitutes a part of the top surface of the cover, and covers the paragraph flange of the floor panel exposed from the notch of the lid main body, and the passage hole together with the inner peripheral edge of the notch. It is a cover for the floor panel to be formed. The passage opening forming surface has a shape with a short length from the joining edge with the lid closing surface, and the length from the joining edge is provided at one of the edge or both side edges of this edge while being the same as the lid closing surface. It has a shape having an opening. The lid closing surface and the passage opening forming surface are
In any case, it is preferable that the thickness is equal to that of the outer peripheral flange of the lid main body, and the edges are aligned with the outer periphery of the lid main body, and are mounted in the notches.

Means for mounting the cover member in the notch include, for example, when the cover is closed, (1) the cover surface is fitted into the notch or placed on and supported by a ridge provided on the inner surface of the notch; (3) The above (1) and (2) are used in combination, wherein the passage opening forming surface to be accommodated in the inside is fitted in the notch or received and supported by a ridge provided on the inner surface of the notch. In order to fit the cover surface into the notch, it is preferable to hold the side edge of the cover surface or the protrusion or protrusion formed on the side edge between the protrusions or protrusions formed in the upper and lower two rows on the inner surface of the notch. The ridges or the like on which the lid surface is to be placed have continuous ridges or steps or rows of two or more intermittent projections, and need to have a shape or arrangement that does not obstruct the passage hole forming surface to be accommodated in the notch. Become. It is preferable that the ridge or the like that receives the passage opening forming surface to be accommodated in the notch is a fitting recess that receives the lower end of the side edge of the passage opening forming surface. The wire opening forming surface may be sandwiched. The passage opening forming surface to be stored in the notch may be formed by forming a guide portion formed of a continuous protruding ridge or a step in the notch or an array of two or more intermittent protrusions on the inner surface of the notch to restrict the storing direction. Since the fitting concave portion and the guide portion uniquely determine the storage position of the passage opening forming surface, they are also the mounting positioning means of the lid member with respect to the notch. In addition, at the time of the passage opening formation, the above-mentioned closing surface and the passage opening formation surface can be configured to have the same fitting, clamping or holding structure in the opposite relationship, but the length is shorter or longer from the joining edge of both. In some cases, when both the lid closing surface and the passage opening forming surface are mounted in the notch with their edges aligned with the outer periphery of the lid body, the passage opening forming surface when closing and the lid closing when forming the passage opening. Since the storage position with respect to the notch differs from the surface, in this case, two fitting receiving portions and guide portions provided on the inner surface of the notch are required.

In the closing lid of the present invention, the notch is closed with a lid member separate from the lid main body. Of course, even when the passage opening is formed, the lid member is always mounted in the notch, so that there is no risk of loss. Further, the closing surface is placed on the paragraph flange exposed from the notch of the lid main body, and the communication hole forming surface covers at least the paragraph flange exposed from the notch of the lid main body. Is not formed on the upper surface of the panel and the upper surface of the lid. In the case where the passage opening forming surface is short in shape from the joining edge with the lid closing surface, while the paragraph flange exposed in the notch of the lid body covers the passage opening forming surface, this passage opening is A connection hole is formed which is surrounded by the joining edge of the forming surface and the opposite edge and both side edges of the joining edge in the notch of the lid main body, and the length from the joining edge is the same as the closing surface and the joining edge and this joining In the case of a shape having an opening that is open to any of the remaining two edges except for the edge, a through hole is formed that is surrounded by the inner peripheral edge of the opening and the opposing edge of the opening in the notch of the lid body. I do. The communication lines and the like drawn from the through hole formed by being surrounded by the through hole forming surface and the notch are protected around by the through hole forming surface and the notch, and the floor panel flange (paragraph flange) is formed. In addition to the edge of the floor panel). Therefore, the passage opening forming surface may cover the paragraph flange so that the paragraph flange is not exposed to the passage opening.

As is apparent from a comparison between FIG. 1 and FIG. 3, when the cover member 1 is mounted with the cover surface 2 horizontal, the notch 9 closed and the communication hole forming surface 5 is set horizontal to form the cover member 1. Is attached, the lid member 1
A communication hole 24 surrounded by the notch 9 is formed.

The opening 4 of the present embodiment is a notch in a floor panel 6 having a substantially rectangular plane whose long side is twice as long as its short side, as shown in FIGS. The step-down flange 7 with respect to the panel upper surface 18 protrudes from the inner peripheral surface. The shape and size of such an opening 4 are usually determined according to the shape of the outlet box to be fitted. The lid body 3 has an outer peripheral flange 20 continuous from the lid upper surface 19.
So that the outer peripheral flange can be placed on the paragraph flange 7.
The outer shape of the opening 20 is substantially the same as that of the opening 4. For example, as shown in FIG. 5, when the floor panels 6, 6 of the same shape are abutted on each other, the opening The opening can be attached across both floor panels 6,6. In this case, the lid body 3 is supported by the two floor panels 6, 6, and the applied load is dispersed and supported by the two floor panels 6, 6,
Load bearing performance can be increased. The lid body 3 is provided with an outer peripheral flange 20.
Is placed on the step-down flange 7 of the opening 4, and a hook-shaped hooking section 8 having elasticity is hung on the step-down flange 7 to be fixed in position in the opening 4.

In the lid body 3, an open notch 9 which is continuous with the periphery of the lid upper surface 19 is provided inward from a portion corresponding to the paragraph flange mounting of the outer peripheral flange 20, as shown in FIG. 2 or FIG. On the inner surface of the notch 9, a guide groove 10 for closing the cover for inserting the passage opening forming surface 5 of the cover member 1 and a guide groove 11 for forming the passage opening for inserting the closing surface 2 are vertically extended. A fitting recess 23 extends from the lower end of the guide groove 10 when the lid is closed. Lid member 1
Is placed on the step-down flange 7 such that the edges of the horizontal closed lid surface 2 or the passage opening forming surface 5 are aligned with the peripheral edge of the lid upper surface of the lid body 3 and are flush with the lid upper surface 19. It is preferred to be mounted in the notch 9. In this example, the guide groove 10 at the time of closing the cover for inserting the communication hole forming surface 5 is shortened, and the notch 9 is located on the inner side (the inner side in FIG. 2).
The guide groove 11 at the time of forming the passage opening for inserting the cover surface 2 is made longer,
The notch 9 is arranged substantially in the middle (in the front in FIG. 2) of the cutout 9 in accordance with the depth of the passage forming surface 5. In this embodiment, a pair of flat holes are formed on the horizontal passage opening forming surface 5 and the lid upper surface 19 so that the lid closing surface 2 is inserted into the passage opening guide groove 11 without mistake when the passage opening is formed. A mark (alignment mark) 27 is provided.
Further, a support ridge 15 on which the side edge of the horizontal lid closing surface 2 or the passage opening forming surface 5 can be placed is provided so as to connect the upper ends of the two guide grooves 10 and 11, and the support ridge 15 is located at a lower level. The holding protrusion 12 corresponding to the upper stage is partially formed along the inner peripheral edge of the notch 9. The support strip 15 and the holding projection 12 are connected to a lid member 1 described later.

Further, in this example, a step is provided on the joining edge 21 so that the accommodated through hole forming surface 5 can be held between the corresponding holding projection 12 and the fitting recess 23 which is continuous with the guide groove 10 when the lid is closed. ing.

As shown in FIGS. 1 to 4, the cover member 1 has a closed surface 2 substantially equal to the shape of the notch 9 and a through hole whose length from the joining edge 21 is substantially half of the closed surface 2. When the notch 9 is closed with the lid closing surface 2 being horizontal and the notch 9 is closed, the communication hole forming surface 5 is inserted into the above-described lid closing guide groove 10, When the communication hole 24 is formed with the communication hole forming surface 5 horizontal, the lid closing surface 2 is inserted into the guide groove 11 when the communication hole is formed, and is attached to the notch 9. As described above, in order to hold the lid member 1 in the notch 9, the side edge of the lid closing surface 2 or the line opening forming surface 5 has
A lid projection 13 is provided to be held between the support strip 15 and the holding projection 12. When the lid closing surface 2 or the passage opening forming surface 5 is inserted into each of the guide grooves 10 and 11, the lid protrusion 13 is sized to be pressed into the groove to prevent rattling of the lid member 1 mounted in the notch 9. And
A function of realizing a more stable mounting state can be added to the lid projection 13.

As shown in FIG. 6, the closing lid of this embodiment is as follows.
After removing from the opening 4 of the floor panel 6, communication line etc.
14 is inserted into the notch 9, and the communication port 14 is inserted into the communication port 24 by inserting the cover surface 2 into the guide groove 11 when forming the communication port with the communication port forming surface 5 being horizontal. The procedure for attaching the lid body 3 to the opening 4 as it is realizes the work of drawing out the communication line 14 and the like. Thus, the communication line 14 and the like 24
When the closing lid is attached to the notch 9, the lid body 3 or the lid member 1 and the paragraph flange 7 are connected to each other. Thus, an accident such as pinching of the communication line 14 can be prevented, and the drawn communication line 14 does not have to be in contact with the stepped flange 7 or the side of the metal floor panel 6. If there is no cover member, in particular, when a communication line or the like is drawn out from a closing cover attached across the two floor panels 6 as shown in FIG. A communication line or the like enters the gap between the two floor panels 6, 6 arranged with a gap,
Each panel 6 may be bent or broken by the stepped flanges 7, which are bent or vibrated by the load, and may be short-circuited in some cases. Thus, the lid member of the present invention greatly enhances the safety of the drawn communication line and the like.

As described above, the lid member according to the present invention is
It not only protects the drawn communication lines and the like from contact with the floor panel, but also has a function of enabling the selection of the formation of the communication port and the closure. That is, the cover member having a substantially L-shape in side view is assigned a closing surface and a passage opening forming surface at the time of closing the passage opening, respectively, thereby forming the passage opening,
The closure is achieved by the choice of both. In order to fulfill this selection function, it is sufficient that the communication port forming surface has a shape that can draw out communication lines and the like while covering at least the paragraph flange exposed from the notch with respect to the closing surface that completely closes the communication port. become.

For example, as shown in FIG. 7 (a perspective view corresponding to FIG. 1), the cover member 17 having the passage opening forming surface 16 provided with the opening 26 opened to the side with respect to the notch 9 also has the above-described example. Similar functions and effects can be obtained. The communication port 24 is provided with the opening 26
And the inner peripheral edge of the notch 9. Lid member of this example
In FIG. 17, as can be seen in FIG. 8 (a perspective view corresponding to FIG. 2), since the size of the outer shape of the lid closing surface 2 and the communication hole forming surface 16 are equal,
A guide portion 22 (virtually formed by the support protrusion 25 and the fitting concave portion 23, which corresponds to the guide groove 11 when the passage opening is formed and the guide groove 10 when the cover is closed (see FIG. 2; see a hatched portion in FIG. 8)). When the cover member 17 is attached to the notch 9 by forming the guide portion 22 in the notch 9 and sharing the guide portion 22 with the passage opening forming surface 16 or the lid closing surface 2 housed in the notch 9 and guiding the same. There is an advantage that there is no need to worry about erroneous storage positions of the closing surface 2 or the passage opening forming surface 16 housed in the notch 9 (the reason why there is no mark is that FIG. 1 and FIG. 7 are compared). . In addition, the cover closing surface 2 when the cover is closed or the passage opening forming surface 16 when the passage opening is formed.
Are placed on the support projections 25 arranged along the inner periphery of the notch 9 and can be sufficiently supported.
In order to restrict the rotation of the fitting 17, a fitting recess 23 into which the lower end of the side edge of the cover surface 2 or the passage opening forming surface 16 housed in the notch 9 is fitted.
Need only be provided in the notch 9.

In the closing lid of each of the above-mentioned examples, the closing surface or the passage opening forming surface is inserted into each of the guide grooves or the guiding portions and the fitting recesses, and the horizontal closing lid surface or the passage opening forming surface is formed on the side edge. The lid projection provided was sandwiched between the clamping projection and the support strip to achieve stable mounting in the notch.For example, the lid body was hooked to the step-down flange of the floor panel by the hook, and the position was fixed. In the same manner as described above, the closed surface or the passage opening forming surface provided with the portion corresponding to the engaging portion is hooked on a support strip or the like, thereby realizing stable attachment to the notch of the lid member. Is also good. Normally, while the floor panel is made of metal, the closing lid is made of resin and a relatively small portion can be easily formed. Therefore, the size, shape and cover member of the closing lid or the communication port, especially the lid, The mounting means may be determined according to the shape of the member.

[0018]

According to the present invention, there is provided a closing lid which can form a communication port simply and in a short time without any labor and labor. Moreover, this closing lid is realized by a detachable lid member, as if a communication line or the like is inserted through an opening provided in the closing lid, so that it comes into contact with the floor panel not only at the time of drawing out work but also after drawing out. There is an advantage that damage to the communication line and the like can be prevented. This eliminates the need for processing that has been performed so that the end face of the paragraph flange does not become an acute angle, and reduces processing costs during floor panel manufacturing.

Furthermore, even with a floor panel made of concrete as a base material, if the closing lid of the present invention is used, communication lines and the like can be drawn out without making contact with concrete. As described above, the present invention enables a communication line or the like to be safely drawn out without requiring processing or material limitation on the floor panel.

Further, the line opening once formed can be closed again by changing the direction of the cover member.
This lid member is always attached to the closing lid irrespective of when the lid is closed or when the line opening is formed, so that there is no risk of loss. Thus, the present invention has eliminated the possibility of the lid member being lost due to the two-part closing lid.
