Description

  The present invention relates to a tile carpet for cable wiring used for laying a cable such as a LAN cable or a power supply cable on a floor, a manufacturing method thereof, and a layout structure thereof. The present invention relates to a tile carpet for cable wiring, a method for manufacturing the cable, and a layout structure for the cable that can be laid without increasing the cost and are low in manufacturing cost.

  In corporate offices, tile carpets are often placed on the floor. The tile carpet is placed on the building-integrated floor. Here, the building-integrated floor is a floor structure made of concrete or the like that forms part of the structure of the building and is not replaced with time. As a tile carpet, for example, one having a cross-sectional structure as shown in FIGS. 1 and 2 of Patent Document 1 (Japanese Patent Application Laid-Open No. 2012-110403) is known. The tile carpet of the type exemplified in Patent Document 1 has a shock-absorbing pile layer on the front side and a backing layer on the back side, and has a square planar shape with a thickness of about 7 mm and a side of about 50 cm. There are many things. The tile carpet not only enhances the aesthetics of the floor, but also has a function of buffering an impact transmitted from the floor to a foot when a person walks on the floor, increasing a frictional resistance with a shoe sole, and making it difficult to slip. Therefore, in the tile carpet, the surface side which is directly stepped on the shoe sole of a person walking in the office is often composed of a rough nylon pile yarn so as to exhibit an impact buffering action and a non-slip action. The back surface of the tile carpet is usually a surface that comes into contact with the upper surface of the building-integrated floor, but when the following cable laying structure is adopted, it comes into contact with the upper surface of the cable laying structure.

  Due to the recent office situation where many office electronic devices such as personal computers, servers, and printers are installed, a cable laying structure for laying cables such as LAN cables and power supply cables is first installed on the building-integrated floor. A tile carpet may be laid on the cable laying structure.

  Patent Document 2 (Japanese Patent Application Laid-Open No. 2012-77573) discloses a floor structure that enables the laying of cables such as LAN cables and power supply cables using the cable laying structure as an “OA panel unit for cable floor wiring and its arrangement structure”. It is disclosed. The OA panel unit for cable floor wiring of Patent Document 2 includes a main panel body (11), a first sub-panel body (21), and a second sub-panel body (31 shown in FIGS. 1, 2, and 3 of Patent Document 2, respectively. ) Are placed next to each other and placed directly on the building-integrated floor (existing floor F) in a grid pattern.

  The main panel body (11) has a straight cable wiring groove (14), and the first sub-panel body (21) and the second sub-panel body (31) are curved cable wiring grooves (24, 34). Have By appropriately selecting and combining any of these three types of panels so that the end of the cable wiring groove on the side surface of each panel coincides with the end of the cable wiring groove on the side surface of another adjacent panel, Each cable wiring groove in the panel is connected to form a communication route (41, 42, 43) for storing a long cable (see FIG. 4 of Patent Document 2).

  Each of these panels is laid on the building-integrated floor (existing floor F) with the cable wiring groove opening facing upward. Because it is laid with the opening facing upwards, when each panel is stepped on with human shoes, the load is buffered to prevent each panel from being damaged, or to hide the cable wiring groove, A floor mat (71) covering the opening may be laid (see paragraphs 0021 and 0050 and FIG. 5 of Patent Document 2). The cable wiring groove on which the cable (51) is not wired may be filled with the groove cover material (61) (see paragraph 0055 of FIG. 5 and FIG. 5).

JP 2012-110403 A JP 2012-77573 A

  Each panel in the OA panel unit for cable floor wiring described in Patent Document 2 described above is made of a synthetic resin plate such as hard vinyl chloride having a side of 50 cm and a thickness of 10 to 12 mm (paragraph 0024 of Patent Document 2). Furthermore, if the floor mat (71) covering each panel is laid in order to buffer the load so as to prevent damage to each panel or to hide the cable wiring groove, the floor surface will be on the upper side by the thickness of the floor mat. Raised. Even if the thickness of the floor mat is thin, it is 5 mm. Therefore, the thickness of the floor structure composed of the cable floor wiring OA panel unit and the floor mat is at least 15 to 17 mm.

  Since the thickness of a normal tile carpet is about 7 mm, when a floor structure in which a floor mat is further placed on the cable laying structure (OA panel unit for cable floor wiring) of Patent Document 2 is laid on the office floor The floor structure is thicker by about 8-10mm than when a normal tile carpet is laid, and the height from the floor to the ceiling is reduced by that much, so the office ceiling feels low, and the office space A feeling of blockage occurs and the comfort of the office is reduced. Also, if the thickness is larger than the carpet thickness (about 7mm) planned for a normal office, the surface of the floor structure (OA panel unit for cable floor wiring and floor mat) is under the existing door of the office entrance / exit. Refurbishment work, such as raising the lower edge of an existing door, will be necessary.

  Furthermore, in the cable laying structure (OA panel unit for cable floor wiring) of Patent Document 2, three types of panels, that is, a main panel body (11), a first sub panel body (21), and a second sub panel body (31) are adjacent to each other. Since it is laid in a grid pattern on the building-integrated floor (existing floor F), which panel should be laid according to the communication route (41, 42, 43) for storing the cable The selection is complicated, and workability at the panel laying site must be reduced.

  The cable laying structure (OA floor unit for cable floor wiring) of Patent Document 2 is laid on a building-integrated floor (existing floor F) so that the opening of the cable wiring groove faces upward. Therefore, in the cable laying structure of Patent Document 2, when the panel is stepped on by a person's shoes, the load is buffered to prevent each panel from being damaged, or to hide the cable wiring groove. It is presumed that it is practically essential to lay a floor mat (71) covering the opening. As described above, the cable laying structure of Patent Document 2 is provided with a shock absorbing buffer, such as a floor mat (71), a tile carpet, etc., for buffering an impact received from a floor when a person walks on the floor or making it difficult to slip. Apart from the non-slip mat, it is a special cable laying structure that is specially provided for cable laying. Therefore, the floor structure in which the cable laying structure (OA panel unit for cable floor wiring) of Patent Document 2 is covered with an impact buffering / non-slip mat does not aim at cable laying, and cushions the shock or makes it difficult to slip. Compared to a normal shock-absorbing / non-slip mat intended only for this purpose, it is much more expensive.

  Therefore, in order to solve such a problem, the present invention is sufficient to have a thickness equivalent to that of a tile carpet for shock buffering / slippery that aims to alleviate the impact felt when walking on the floor and to make it difficult to slip. The purpose of the present invention is to provide a tile carpet for cable wiring, which is excellent in workability at the laying site and has a low manufacturing cost, and its arrangement structure.

The straight cuts 131, 132, 141, 142 are parallel to the left side hk and the right side ij of the square. The intervals between the straight cuts 111 and 112, the intervals between the straight cuts 121 and 122, the intervals between the straight cuts 131 and 132, and the intervals between the straight cuts 141 and 142 are all constant values f.

  Among the partial lower layer members, A to D and F to I are rectangles, and E is a circle. The partial lower layer members J1 to J4 are substantially triangular with the partial circular cut 152 and two straight cuts orthogonal to each other as the edges. In the present embodiment, the lower layer members are partial lower layer members A, B, C, D, E, F, G, H, I, J1, J2, J3, J4, linear groove filling members 110, 120, 130. , 140 and the circular groove filling member 150 (the area where two groove filling members overlap each other occupies a part of the lower layer member, and the area where the two groove filling members overlap is the other The groove filling member is assumed to be missing.) The same applies to other embodiments described later.

  In the tile carpet, as described above, the surface that is placed on the building-integrated floor is the back surface, and the surface that directly contacts the pedestrian sole is the front surface. The figure and the figures to be described later appear upside down from the state when they are placed on the building-integrated floor. It is drawn. Accordingly, the plan view is a view seen from the back side of the tile carpet, and in the sectional view, the back side of the tile carpet is drawn on the upper side of the paper surface.

  Following the description of the first embodiment, the cable wiring tile carpets of the second and third embodiments, the manufacturing method thereof, and a plurality of the cable wiring tile carpets of the embodiments are arranged below. A cable wiring tile carpet arrangement structure will be described. In addition, each figure referred in description is drawn according to the above-mentioned drawing policy. That is, in each drawing showing the embodiment of the present invention, the plan view is a view seen from the back side of the tile carpet, and in the sectional view, the lower layer member of each tile carpet appears on the upper side of the drawing, and the upper layer member K is It appears at the bottom of the figure.

  The description of the tile carpet for cable wiring according to the first embodiment will be continued with reference to FIGS. 1 to 4 again. The cable wiring tile carpet of the first embodiment is formed by bonding a lower layer member and an upper layer member K with an adhesive. Reference numeral 10 denotes an adhesive surface between the upper layer member K and the lower layer member. The upper layer member K is a square having a thickness t of 3.5 mm and a side length of 50 cm, and is composed of, for example, the surface pile layer 202, the back stitch 207 and the primary adhesive layer 206a in the conventional tile carpet of FIG. is there. The lower layer member is a plate having a side length of 50 cm and a thickness t of 3.5 mm. A straight cut 111, 112 is formed on one flexible plate made of vinyl chloride resin. , 121, 122, 131, 132, 141, 142, a circular cut 151, and a partial circular cut 152. The partial circular cut 152 forms a boundary surface between each of the partial lower layer members J1, J2, J3, and J4 and the circular groove filling member 150. The depth of each of these cuts is the same as the thickness of the flexible plate. Therefore, this flexible plate-like body is originally one (in a state before the cut is made), but is divided by each cut. Regions A, B, C, D, E, F, G, H, I, J1, J2, J3, and J4 divided by making a cut in the lower layer member are partial lower layer members, regions 110, 120, 130, and 140. Is a linear groove filling member, and region 150 is a circular groove filling member.

  The dimension of each part in the tile carpet for cable wiring (1st Embodiment) of FIG. 1 is a: 50cm, b: 20cm, c: 15cm, f: 6mm. The upper layer member K and the lower layer member are bonded with an adhesive. This adhesive is a non-curing type that does not cure over time. Therefore, the linear groove filling members 110, 120, 130, and 140 and the circular groove filling member 150 hold other parts by hand or press against the floor with a foot or the like, and end of each of the groove filling members. Can be peeled from the upper layer member K by squeezing with a nipper or pliers and pulling in a direction perpendicular to the bonding surface 10. In addition, since these linear groove filling members 110, 120, 130, and 140 are subdivided for each region having each cut as a boundary, they can be individually separated from the upper layer member K for each subdivided region.

  As shown in FIG. 1, the straight groove filling members 110 and 120 are cut at straight cuts 131, 132, 141, and 142. Similarly, the straight groove filling members 130 and 140 are cut at straight cut lines 111, 112, 121, and 122. Accordingly, each of the linear groove filling members 110, 120, 130, and 140 is divided into three elongated portions having a width f and two square portions having a small side f, and is divided into a total of five portions. In addition, as shown in FIG. 1, the square portion having a small side f is present at four locations, and the linear groove filling members 110 and 120 that are long in the horizontal direction and the linear groove that is long in the vertical direction. It is a part belonging to both the filling members 130 and 140. In FIG. 3, the portions belonging to both the linear groove filling member 110 that is long in the horizontal direction and the linear groove filling member 130 that is long in the vertical direction are denoted by reference numerals 110 and 130, and the straight groove filling that is long in the horizontal direction Parts belonging to both the member 110 and the linear groove filling member 140 that is long in the vertical direction are indicated by reference numerals 110 and 140.

  Each of the subdivided portions of these linear groove filling members 110, 120, 130, and 140 can be individually separated from the upper layer member K as described above. On the other hand, a partial region of the circular groove filling member 150 overlaps with a partial region of the linear groove filling members 110, 120, 130, and 140 (the middle one of the three elongated portions having the width f). Therefore, when peeling the circular groove filling member 150 from the upper layer member K, together with a partial region (the middle one of the three elongated portions having the width f) of the linear groove filling member 110, 120, 130, 140. Is peeled off. In FIG. 2, reference numerals 130 and 150 are assigned to portions belonging to both the linear groove filling member 130 and the circular groove filling member 150, and portions belonging to both the linear groove filling member 140 and the circular groove filling member 150. Are shown with reference numerals 140 and 150.

  5 shows a state where the linear groove filling members 110, 120, 130, 140 and the circular groove filling member 150 in the tile carpet 1 for cable wiring according to the first embodiment of the present invention shown in FIG. FIG. The one-dot chain line RR is a line that passes through the center o of the cable wiring tile carpet 1 and is parallel to the left side hk of the cable wiring tile carpet 1. 6 and 7 are a sectional view taken along the line PP and a sectional view taken along the line QQ, respectively, of the tile carpet for cable wiring in FIG. FIG. 8 is a partially enlarged sectional view of the cable wiring tile carpet of FIG. In the figure, 11, 12, 13 and 14 are linear grooves formed by peeling the linear groove filling members 110, 120, 130 and 140 of FIG. 1 from the upper layer member K, respectively. These correspond to the first, second, third and fourth linear grooves, respectively. A circular groove 15 is formed by peeling the circular groove filling member 150 from the upper layer member K. Further, 13d and 13e in FIG. 8 are side walls of the linear groove 13, and are also end faces of the partial lower layer members D and E, respectively. Note that the straight grooves 11 and 12 have groove ends located on the sides hk and ij, respectively, and the straight grooves 13 and 14 have groove ends located on the sides hj and kj, respectively. Since these groove | channels 11, 12, 13, and 14 are formed so that a groove end may be located in either of four sides of a square, it is an example of the communication groove | channel between sides in a claim. Moreover, it enters from the lower end of the linear groove 13 and is a part of the circular groove 15, passing through the groove between the substantially triangular partial lower layer member J 1 and the circular partial lower layer member E, to the right groove end of the linear groove 11. The groove of the outgoing route is an example of the communication groove between the sides.

  FIG. 9 is a plan view showing an example of a cable wiring tile carpet arrangement structure in which a plurality of cable wiring tile carpets in the state of FIG. 5 are arranged vertically and horizontally in a grid pattern. For simplification of explanation, FIG. 9 shows an example in which four tiles for cable wiring are arranged vertically and horizontally. In a practical situation, the number to be arranged vertically and horizontally can be arbitrarily selected, and since it is usually spread all over the floor of the room, a larger number are similarly arranged in a grid pattern.

In FIG. 9, reference numerals 11 ₁ , 12 ₁ ... 44 ₁ surrounded by [] like [11 ₁ ], [12 ₁ ],... [44 ₁ ] are respectively shown in FIG. The tile carpet 1 for cable wiring is shown. Reference numerals 51 and 52 denote cables such as a LAN cable and a power feeding cable. x1i, x2i,..., x8i and x1o, x2o,..., x8o are groove ends of the linear grooves 13 and 14, respectively, and y1i, y2i,. ... Y8o are groove ends of the linear grooves 12 and 11, respectively.

  The straight grooves 11, 12, 13, and 14 and the circular groove 15 have a depth t of 3.5 mm and a width f of 6 mm, and accommodate cables such as LAN cables and power supply cables. In the example of FIG. 9, the cable 51 is wired between the groove ends x4i to y4i, and the cable 52 is wired between the groove ends x5i to y6o.

FIG. 9 shows an example using the cable wiring tile carpet of FIG. 5 in a state where all the groove filling members are peeled off. However, it suffices if there are only grooves serving as a route for actually laying the cable, and only the groove filling member for forming these grooves may be peeled off. In the example of FIG. 9, in order to route the cable 51, it is sufficient to peel only some of the groove filling members in the cable wiring tile carpets 21 ₁ , 22 _1, and 12 ₁ . Further, in order to route the cables 52, tile cabling carpet _{31 1,} 32 1, 33 _1, and delivers the 43 ₁ sufficient to peel only a portion of the groove filling member. Therefore, if the route for laying the cable is designed in advance and only the groove filling member of the necessary part is peeled off, the trouble of peeling can be omitted and the groove is not provided in an unnecessary area. Thus, the uniformity of elasticity on the entire surface of the cable wiring tile carpet 1 can be maintained.

  As can be seen from the plan views shown in FIG. 1 and FIG. 5, the planar shape of the cable wiring tile carpet 1 of the first embodiment is a square, a line PP passing through the center o and parallel to the upper side hi and the center o. And symmetric with respect to the line RR parallel to the left side hk and the diagonal lines hj and ik of the square. Therefore, without considering the vertical and horizontal directions of each cable wiring tile carpet 1, simply arranging a plurality of cable wiring tile carpets 1 in a grid pattern as shown in FIG. The groove ends of the linear grooves 11, 12, 13, and 14 in the tile carpet 1 naturally abut on the groove ends of the linear grooves 11, 12, 13, and 14 in the other adjacent tile carpets 1 for cable wiring. Therefore, when the cable wiring tile carpet 1 is configured using the cable wiring tile carpet 1 of the present embodiment, even if the tile carpet 1 is arranged in the direction shown in FIGS. Even if it is rotated 90 degrees, 180 degrees, or 270 degrees, each groove can be provided so that the groove ends abut against each other, so that anyone who installs tile carpets does not need special skills. But it can be done easily in a short time.

  The cable wiring tile carpet 1 according to the first embodiment of the present invention shown in FIGS. 1 to 8 is formed with a groove into which a cable such as a LAN cable can be fitted just by making a cut in the lower layer member. For the purpose of shock buffering / slippery, the purpose is to alleviate the impact felt when walking on the floor and to make it difficult to slip because only the tile carpet made of the lower layer member is sufficient and no special structure is required to accommodate the cable. Same thickness as a normal tile carpet. Therefore, by laying the cable carpet tile carpet 1 on the floor of the office, the distance between the lower end of the door and the floor is sufficient as in the case of a normal tile carpet, and construction is required to raise the lower end of the door exceptionally. Instead, the tile carpet 1 for cable wiring can be laid easily and inexpensively. Further, for example, in the cable laying structure (OA panel unit for cable floor wiring) of Patent Document 2, an impact buffering / slippery mat for buffering an impact received from the floor when a person walks on the floor or making it difficult to slip. Separately, a special cable laying structure is required for cable laying, but the cable wiring tile carpet 1 of this embodiment is manufactured by making a cut in the depth of the thickness of the lower layer member. It can be manufactured at low cost. In addition, the work to remove the groove filling member from the upper layer member can also be done at the tile carpet laying site, so the cable laying path can be set freely so as to correspond to the situation at the site, and the work on site is flexible. Are better.

  FIG. 10 is a plan view showing an example of a cable wiring tile carpet arrangement structure in which eight cable wiring tile carpets in the state of FIG. 5 are arranged vertically and horizontally in a grid pattern. Reference numerals 53, 54, 55 and 56 denote cables such as a LAN cable and a power feeding cable. x1i, x2i... x16i and x1io, x2o... x16o are groove ends of the linear grooves 13 and 14, and y1i, y2i... y16i and y1o, y2o. ... Y16o is the groove end of the linear grooves 12 and 11. Similarly to the cables 51 and 52 in the example of FIG. 9, the cable 54 can be routed along the path from the groove end on the lower side to the groove end on the left side, and the cable 56 can be routed along the path from the groove end on the lower side to the groove end on the right side. FIG. 10 further shows an example in which a cable 53 is routed along a path from a lower groove end to another lower groove end, and a cable 55 is routed straight from the lower groove end to the upper groove end.

  FIG. 11 is a view showing a second embodiment of the tile carpet for cable wiring according to the present invention, and is a plan view showing a state where the groove filling member is peeled off from the upper layer member K as in FIG. The difference between the cable wiring tile carpet 2 of the second embodiment of FIG. 11 and the cable wiring tile carpet 1 of the first embodiment shown in FIGS. 1 to 8 is that the partial lower layer member B is semicircular. The groove 16 (corresponding to the first semicircular groove in the claims) is provided in the partial lower layer member H, and the semicircular groove 17 (corresponding to the second semicircular groove in the claims) is provided. There are certain points and the other points are the same as in the first embodiment. The planar shape of the semicircular grooves 16 and 17 may be a shape approximate to a semicircular shape, and does not need to be strictly a semicircular shape.

  FIG. 12 is a plan view showing an example of a cable wiring tile carpet arrangement structure in which a plurality of cable wiring tile carpets of FIG. 11 are arranged vertically and horizontally in a grid pattern. For simplification of explanation, FIG. 12 shows an example in which four tiles for cable wiring are arranged vertically and horizontally. In practical situations, the number of items arranged vertically and horizontally can be selected arbitrarily, and since it is usually spread all over the floor surface of the room, many more are arranged in a grid pattern as well. This is the same as described for the ninth example.

In FIG. 12, reference numerals 11 ₂ , 12 ₂ ... 44 ₂ enclosed in [] like [11 ₂ ], [12 ₂ ],... [44 ₂ ] are respectively shown in FIG. The tile carpet 2 for cable wiring is shown. Reference numerals 57, 58, 59, and 60 denote cables such as a LAN cable and a power feeding cable. As in FIG. 9, x1i, x2i... X8i and x1o, x2o... X8o are groove ends of the linear grooves 13 and 14, and y1i, y2i. y1o, y2o... y8o are groove ends of the linear grooves 12 and 11.

  In the example of FIG. 12, the cable 57 is routed between the lower side groove end x1i and the left side groove end y5i, the cable 58 is routed between the lower side groove end x3i and the upper side groove end x6o, and the cable 59 is routed from the lower side groove end x6i. The cable 60 is wired between the groove end x8o on the upper side and the cable 60 is wired between the groove end x8i on the lower side and the groove end y2o on the right side. As can be seen from these wiring examples, in the cable wiring tile carpet arrangement structure using a plurality of cable wiring tile carpets in FIG. 11, the cables inserted from the lower side can be taken out from the left side, the upper side, and the right side. By providing the circular grooves 16 and 17, the degree of freedom in selecting the groove ends that serve as the cable inlet and outlet is improved as compared with the first embodiment. Further, not only the degree of freedom in selecting the groove end, but also the degree of freedom in selecting the cable path from the inlet groove end to the outlet groove end is increased. Here, the groove ends are referred to as inlets and outlets. However, if one of the groove ends in the cable-wiring tile carpet arrangement structure is referred to as an inlet for one cable laying path, the other is the outlet. For example, regarding the laying route of the cable 57, if the groove end x1i is the entrance, the groove end y5i is the exit.

  As can be seen from the plan view shown in FIG. 11, the planar shape of the cable wiring tile carpet 2 according to the second embodiment is a square, and passes through the line RR and the center o passing through the center o and parallel to the left and right sides. The line PP is symmetrical with respect to the line PP parallel to the upper and lower sides. Therefore, as long as the vertical direction of each cable wiring tile carpet 2 is aligned, the plurality of cable wiring tile carpets 1 can be simply arranged in a grid pattern as shown in FIG. The groove ends of the straight grooves 11, 12, 13 and 14 naturally come into contact with the groove ends of the straight grooves 11, 12, 13, and 14 in the other adjacent tile carpets 1 for cable wiring. Since aligning the left and right directions also aligns the top and bottom directions, if either one of the top and bottom directions or the left and right directions are aligned and arranged in a grid pattern, the tile wiring arrangement structure for cable wiring in FIG. Can be constructed easily.

  However, unlike the first embodiment of FIGS. 1 to 8, the line symmetry about the square diagonal lines hj, ik which is the planar shape of the cable wiring tile carpet 2 is not in the embodiment of FIG. Aligning the top and bottom directions (and thus aligning the left and right directions) is necessary to form grooves in a uniform pattern as shown in FIG. Therefore, in the cable wiring tile carpet arrangement structure in which a plurality of cable wiring tile carpets 2 are arranged on the floor in a grid pattern, when the direction of the upper side hi of the cable wiring tile carpet 2 is viewed, FIG. When the direction and the direction orthogonal to the direction of FIG. 11 are mixed, no groove is formed in the uniform pattern as shown in FIG. However, in the embodiment of FIG. 11 as well, the linear grooves 11, 12, 13, and 14 have line symmetry with respect to the diagonal lines hj, ik of the square, so that a plurality of cable wiring tile carpets 2 are arranged in a grid pattern. 11, the cable wiring tile carpet 2 in the direction of FIG. 11 and the cable wiring tile carpet 2 in FIG. The groove ends of the grooves 11, 12, 13, and 14 abut each other between adjacent cable wiring tile carpets 2, and a wiring groove path can be formed at least in the same pattern as in the first embodiment.

  The cable wiring tile carpet 2 of FIG. 11 which is the second embodiment of the present invention and the arrangement structure of FIG. 12 using the same are as thin as a normal tile carpet, while having a LAN cable or the like. Since it has a groove to fit the cable, it should be as thick as a normal tile carpet, easy to manufacture and inexpensive to manufacture, and flexible in the selection of the cable laying route in laying work, and requires skill As with the cable wiring tile carpet 1 and the arrangement structure of the first embodiment described above, it is possible to obtain excellent effects such as easy laying and the like.

  FIG. 13 is a view showing a third embodiment of the tile carpet for cable wiring according to the present invention, and is a plan view showing a state in which the groove filling member is peeled off from the upper layer member K, similarly to FIGS. . The difference between the cable wiring tile carpet 3 of the third embodiment of FIG. 13 and the cable wiring tile carpet 2 of the second embodiment shown in FIG. 11 is that the partial lower layer member D has a semicircular groove 18 ( Is equivalent to the third semicircular groove in the claims), and the semi-circular groove 19 (corresponding to the fourth semicircular groove in the claims) is provided in the partial lower layer member F. In other respects, the second embodiment is the same as the second embodiment. The planar shape of the semicircular grooves 18 and 19 may be a shape approximate to a semicircular shape, and does not need to be strictly a semicircular shape.

  FIG. 14 is a plan view showing an example of a cable wiring tile carpet arrangement structure in which a plurality of cable wiring tile carpets of FIG. 13 are arranged vertically and horizontally in a grid pattern. FIG. 14 shows an example in which four cable-wiring tile carpets 3 are arranged vertically and horizontally for the sake of simplicity. In practical situations, the number of items arranged vertically and horizontally can be selected arbitrarily, and since it is usually spread all over the floor surface of the room, many more are arranged in a grid pattern as well. 9 and FIG. 12 are the same as described above.

In FIG. 14, reference numerals 11 ₃ , 12 ₃ ... 44 ₃ enclosed in [] like [11 ₃ ], [12 ₃ ],... [44 ₃ ] are respectively shown in FIG. The tile carpet 3 for cable wiring is shown. Reference numerals 61, 62, 63, and 64 denote cables such as a LAN cable and a power feeding cable. 9 and 12, x1i, x2i,..., X8i and x1o, x2o,..., X8o are groove ends of the linear grooves 13 and 14, and y1i, y2i,. ... Y8i and y1o, y2o... Y8o are groove ends of the linear grooves 12 and 11.

  In the cable wiring tile carpet (third embodiment), semicircular grooves 18 and 19 are provided. Therefore, in the cable wiring tile carpet arrangement structure shown in FIG. The degree of freedom in selecting the groove end is further improved compared to the second embodiment. In addition, in the tile carpet for cable wiring shown in FIG. 13 (third embodiment), not only the degree of freedom in selecting the groove end but also the degree of freedom in selecting the cable path from the groove end of the inlet to the groove end of the outlet is increased. For example, although the cables 61 to 64 are illustrated in FIG. 14, the laying paths of these cables 61 to 64 are the example of FIG. 12 (the arrangement of the tile carpet for cable wiring using the tile carpet for cable wiring of the second embodiment) This is a route that cannot be selected in (Structure).

  As can be seen from the plan view shown in FIG. 13, the planar shape of the cable wiring tile carpet 3 of the third embodiment is a square, the line PP passing through the center o and parallel to the upper side hi, and the left side passing through the center o. It is line symmetric with respect to the line RR parallel to hk and the diagonals hj and ik of the square. Therefore, without considering the vertical and horizontal directions of each cable wiring tile carpet 1, simply arranging a plurality of cable wiring tile carpets 1 in a grid pattern as shown in FIG. The groove ends of the linear grooves 11, 12, 13, and 14 in the tile carpet 1 naturally abut on the groove ends of the linear grooves 11, 12, 13, and 14 in the other adjacent tile carpets 1 for cable wiring. Therefore, the tile carpet construction work of configuring the cable wiring tile carpet arrangement structure using the cable wiring tile carpet 1 according to the present embodiment has no possibility of misplacement, and thus requires no special skill. Can be easily done in a short time.

  The cable wiring tile carpet 3 of FIG. 13 which is the third embodiment of the present invention and the arrangement structure of FIG. 14 using the same are the same as those of a normal tile carpet. Since it has a groove to fit the cable, it should be as thick as a normal tile carpet, easy to manufacture and inexpensive to manufacture, and flexible in the selection of the cable laying route in laying work, and requires skill As in the first and second embodiments of the cable wiring tile carpets 1 and 2 and the arrangement structure thereof, excellent effects can be achieved.
