  First, the configuration of the present embodiment will be described.
  As shown in FIG. 3, the sill 10 guides the lower ends of the two sliding doors 11 for opening and closing the opening 82 of the wall 81 formed between the Japanese-style room 18 and the Western-style room 19. In the floor material, a tatami 83 is formed on the Japanese-style room 18 side, and a flooring 84 made of wood plywood is formed on the Western-style room 19 side. Note that the upper part of the opening part 82 is formed with a duck 17 that is fixed to the upper part of the opening part 82 and guides the upper end of the sliding door 11.
[0027]
  The sill 10 has a frame body 14 having a sill groove 80 formed on the upper surface thereof and recessed in a groove shape along the longitudinal direction for fitting the sliding door 11, and a sill groove member 20 fitted into the bottom surface of the sill groove 80. And. The frame body 14 includes a fixing member 15 fixed to the lower surface of the opening 82 of the building frame, and a surface member 16 having a substantially F-shaped vertical cross section fixed to the indoor surface side of the fixing member 15. ing.
  Further, a tatami mat 88 that makes up the side surface of the frame body 14 is fixed to the side edge of the frame body 14 on the side of the Japanese-style room 18. The frame body 14 composed of the fixing member 15 and the surface member 17 is fixed to the upper surface of the opening 82 and is also used as the duck 17.
[0028]
  The sill groove member 20 is formed as a groove depth adjusting member 70 that is fitted into the sill groove 80 of the frame body 14 in order to adjust the depth of the sill groove 80.
  This sill groove member 20 is made of a material harder than the main body part 30 and the main body part 30 fitted into the bottom surface of the sill groove 80, and is arranged along the longitudinal direction of the main body part 30 on the upper surface of the main body part 30. 11 includes a sliding portion 40 having a substantially rectangular longitudinal cross-sectional shape with which the lower end surface of 11 comes into contact.
  Further, the sill groove member 20 has a recessed groove 89 that can be fitted into the engaging protrusion 85 of the frame body 14 on the lower surface side thereof, and the engaging protrusion of the frame body 14 is formed on the inner surface side of the recessed groove 89. In order to mesh with the portion 85, a concavo-convex portion 91 having a sawtooth shape in the longitudinal section is formed. On the upper surface side of the sill groove member 20, a partition portion 31 that protrudes along the longitudinal direction inside the sill groove 80 is formed in order to partition the inside of the sill groove 80 along the longitudinal direction.
[0029]
  A plurality of the sliding portions 40 are embedded in the width direction of the sill groove member 20 at an interval smaller than the thickness of the sliding door 11. Specifically, four sliding portions 40 are embedded in the groove surface for guiding the single sliding door 11 partitioned by the partition portion 31 along the longitudinal direction, and one sill groove is formed. A total of eight sliding portions 40 are embedded in the member 20. The sliding portion 40 is formed so that the upper surface thereof is flush with the surface of the sill groove member 20.
[0030]
  The main body portion 30 of the sill groove member 20 is formed by foaming a composition mainly composed of resin and fine-grain wood powder.
  Specifically, the main body 30 is made of a resin obtained by mixing a powder prepared by supporting a hard fine powder having a diameter smaller than that of the fine powder on the surface of a fine powder of cellulose-based material mainly composed of wood powder. It is formed so as to exhibit a wood grain pattern by color molding. And the main-body part 30 is improving the wood texture in an external appearance and a touch feeling by making the said raw material low foam.
  Here, in the above description, the “cellulosic material” includes natural sawwood, sawdust, rice straw, bacus and the like. The “fine powder having a smaller diameter and harder than the fine powder” refers to fine powder of titanium oxide, ferrite, aluminum, nickel, silver, ceramic, calcium carbonate, or the like. The “coloring resin” material is a colored pigment, for example, an inorganic pigment such as iron oxide, cadmium yellow, or carbon black. Also, “presenting a wood grain pattern by coloring the resin” means that the resin itself is colored using the above-mentioned pigment, so that the wood grain pattern is presented not only on the surface but also inside. It is what is formed. Thereby, even if the surface of the main body 30 is repeatedly contacted with the surrounding peripheral members such as the sliding door 11 and worn away, the surface wood grain pattern does not disappear and the appearance of a good wood grain pattern is maintained. It is something that can be done.
[0031]
  Of course, the material of the main body 30 is not limited to the above-mentioned material, but is formed of resin and wood powder without having a grain pattern on the surface, or formed of ordinary resin only. It includes what is.
  On the other hand, the sliding portion 40 is made of non-foamed resin, the inside is dense, and the hardness is set to be harder than that of the main body portion 30 so that even if the sliding door 11 repeatedly contacts, it will not wear out due to wear. Is formed. And the main-body part 30 and the sliding part 40 of this sill groove member 20 are elongate extrusion-molded articles obtained by integrally extruding both.
[0032]
  Next, the operation and effect of the above-described embodiment will be described.
  In the present embodiment, the sill groove member 20 is made of a material harder than the main body part 30 and the main body part 30 fitted into the bottom surface of the sill groove 80, and the upper surface of the main body part 30 extends along the longitudinal direction of the main body part 30. And a sliding portion 40 that is disposed and contacts the lower end surface of the sliding door 11. That is, the lower end surface of the sliding door 11 is in contact with the sliding portion 40, and the sliding portion 40 itself is formed of a material harder than the main body portion 30, so that it is less likely to wear than the main body portion 30 contacts. Further, since the sliding portion 40 is formed on the upper surface of the main body portion 30, the lower end surface of the sliding door 11 does not contact the main body portion 30, or the lower end surface of the sliding door 11 and the main body portion 30 even if contacted. Furthermore, it is possible to suppress wear and abrasion. Thereby, it is not necessary to set the material of the main body 30 to a hard material in consideration of wear with the lower end surface of the sliding door 11, and the material selection range can be selected from a wide range.
  Therefore, the main body 30 is not limited to a material having a hard material, and can be selected from materials having various textures without being affected by the hardness. Can be formed.
[0033]
  In the present embodiment, a plurality of sliding portions 40 are embedded in the width direction of the sill groove member 20 with an interval smaller than the thickness of the sliding door 11. Therefore, even if the lower end surface of the sliding door 11 is placed on the upper surface of the sill groove member 20 and repeatedly slides, the lower end surface of the sliding door 11 always slides on at least one sliding portion 40. As a result, the sliding portion 40 comes into contact with the lower end surface of the sliding door 11 and holds the sliding door 11. Thereby, it is possible to suppress the progress of wear between the lower end surface of the sliding door 11 and the main body 30.
[0034]
  And since the sliding part 40 is formed at intervals in the width direction instead of the entire surface of the sill groove member 20, the material of the sliding part 40 is compared with the case where the sliding part 40 is formed on the entire surface. Can be reduced. And since the upper surface of the sliding portion 40 is formed so as to be flush with the surface of the sill groove member 20, the upper surface of the sill groove member 20 can be formed in a flat plane, and the appearance is good. Can be a thing. Also,This sill groove member 20 ofSince there is no unevenness such as the sliding portion 40 on the upper surface, even when stepped on the sole, the feel can be improved. Further, since there is no unevenness such as the sliding portion 40, dust or the like does not accumulate between the unevenness, and the cleaning operation of the upper surface of the sill groove member 20 can be facilitated.
[0035]
  The sill groove member 20 according to the present embodiment is formed as a groove depth adjusting member 70 that is fitted inside the sill groove 80. In other words, by inserting the sill groove member 20 into the sill groove 80, the groove depth of the sill groove 80 can be reduced by the thickness of the sill groove member 20. Thereby, the groove depth of the sill groove 80 can be adjusted.
  Further, by using the groove depth adjusting member 70, as shown in FIG. 3, the frame main body 14 can be fixed to the lower portion of the opening 82 and used as the sill 10, and the frame main body 14 can be used. If the groove depth adjusting member 70 is removed from the upper portion of the opening 82 and fixed, the head 17 can be used. That is, the frame main body 14 can be used as a common member for the duck 17 and the sill 10 by properly using the sill groove member 20. Thereby, parts can be shared, the number of necessary members can be reduced, and the management and storage of the members can be facilitated.
[0036]
  In the present embodiment, the main body portion 30 of the sill groove member 20 is formed by foaming a composition mainly composed of a resin and fine wood powder. That is, since wood powder is contained in the main body 30, the touch of the surface of the main body 30 with the hand becomes a woody texture, and there is no smooth feel of the surface of resin or vinyl chloride, A good hand feeling that fits comfortably in the hand can be obtained. Moreover, by making it foam, the inside is not dense, and the wood texture peculiar to wood containing the conduit | pipe etc. inside can be obtained.
[0037]
  Further, since the main body 30 is made of the above-described material and has a resin, the main body 30 has a smaller water absorption than the wood material and does not shrink due to moisture absorption. Thereby, compared with a wooden material, it can be made excellent in the uniformity as a material which is hard to warp, hard to twist, and hard to rot. Since the sliding portion 40 is formed from a non-foamed resin, the inside thereof can be made dense so that it is hard and hard to wear.
[0038]
  And since the main-body part 30 and the sliding part 40 of the sill groove member 20 are formed by integrally extruding both, they have the same cross-sectional shape in the longitudinal direction, and a long material of any length Can be easily obtained. Thereby, even if the dimensional shape of the sill 10 changes, the sill groove member 20 having various lengths can be easily prepared.
  In other words, in the present embodiment, as described above, it is possible to easily obtain an elongated integrally molded product having a different surface texture and hardness.
[0039]

  In this embodiment, since the number of sliding portions 40 is increased as compared with the first embodiment, the sliding portion 40 and the main body are supported by more sliding portions 40 supporting the lower end surface of the sliding door 11. The wear of the portion 30 can be further suppressed. That is, even when the sliding door 11 is heavy, the load applied to one sliding portion 40 can be suppressed. As a result, when the sliding door 11 having a large weight is used or when the sliding door 11 is slid many times, the amount of wear can be suppressed. In addition, since it is difficult to wear, the formation of irregularities due to wear of the surface of the sill groove member 20 can be suppressed, and the sliding property of the sliding door 11 can be improved.
[0041]
