Description

  The present invention relates to a column unit installed so as to stretch between a ceiling provided with a collar and a floor surface.

  There is a strut that is retrofitted between the ceiling and the floor surface as an assisting tool for elderly people and those who need care support to walk indoors in daily life.

  As shown in, for example, Patent Document 1, this strut is made up of a base installed on the floor, a support installed upright on the base, and a ceiling contact that is attached to the upper end of the support and contacts the ceiling. The ceiling abutting portion has a slender oval shape on the top surface and is formed flat.

JP 2008-63760 A

  As shown in the above-mentioned Patent Document 1, in a strut column whose upper surface of the ceiling abutting portion is an elongated oval shape, if the ceiling surface is flat like the ceiling of a Western-style room, the ceiling abutting portion is placed on the ceiling surface. Since the upper surface can be brought into contact with the entire area, there is no hindrance in the installation, but when a large number of ridges are installed on the ceiling surface like the ceiling of a Japanese-style room, the adjacent ridges Since the ceiling plate between the edges is thin and has no strength, it is necessary to avoid the ceiling plate and bring the upper surface of the ceiling contact portion into contact with the lower end surface of the flange edge. That is, it is necessary to abut the lower end surfaces of two adjacent ridges in a state where the ceiling contact portion of the column unit is in a posture intersecting with the ridges.

  However, when a conventional column unit is installed on a ceiling with a ridge in the above-described form, for example, the user leans against the column, or grips the column and pushes or pulls it strongly through the column. When a force in a direction crossing the heel edge is applied to the ceiling contact portion, the contact area with the heel edge 201 occupying the upper surface of the ceiling contact portion 100 is small, so as shown by a two-dot chain line in FIG. The ceiling contact portion 100 moves relatively easily (see arrow S in the figure), and the rear end (the left end in the figure) 100a in the pressed direction is one of the two. There is a risk that the end 100a of the heel edge 201 will come off from the lower end surface of the heel edge 201 and the detached end portion 100a will hit the ceiling board 202 between the rim edges 201, 201, resulting in damage to the ceiling board 202.

  In this regard, if the overall length dimension of the ceiling contact portion in the longitudinal direction is made as large as possible so as to cross over the lower end surfaces of the three adjacent ridges, the ceiling contact portion is as described above. Even if it moves slightly, the ceiling contact portion is in contact with at least the lower end surfaces of the two adjacent edges, so that the above-described breakage of the ceiling plate can be prevented. However, in that case, since the overall length of the ceiling contact portion becomes too long, there is a concern that the manufacturing cost and weight increase. In addition, there is no problem when installing the column unit close to the wall perpendicular to the heel edge, but when installing the column unit close to the wall surface parallel to the ridge edge, the length of the ceiling abutting part is large. Since the column unit goes on a business trip inside the room, there is a problem that it is not easy to use. That is, since the ceiling abutting portion has a length extending over three edges, the distance between the end of the ceiling abutting portion and the column is long. Even if the column unit is installed so as to be in contact with the wall surface, the distance between the wall surface and the column is not shorter than the distance between the end of the ceiling contact portion and the column, and the column is considerably separated from the wall. As a result, the support unit travels to the inside of the room.

  In view of such circumstances, the present invention provides a strut unit that is installed so as to stretch between a ceiling provided with a collar and a floor surface, and is firmly fixed so that the ceiling contact portion does not move from the collar. The purpose is to enable installation.

  The present invention relates to a column unit that is erected in a stretched state between a ceiling and a floor surface on which a plurality of flanges are provided, and a base installed on the floor surface, And a ceiling abutting portion attached to the upper end of the column, and the ceiling abutting portion includes at least an outer side and an inner side of two adjacent ridges of the ridges. At least one of the outer edge and the inner edge of one of the two adjacent edges when the ceiling contact portion receives a force in a direction that intersects the edge, and is located on one side It is characterized by the provision of a stopper that comes into contact with.

  Here, the stopper of the present invention is at least one of an outer stopper disposed on each outer side of two adjacent ridges and an inner stopper disposed on each inner side of two adjacent ridges. It is.

  In this configuration, the ceiling abutting portion is positioned so as to cross over the two adjacent ridges of the ceiling provided with the ridges, and the upper surfaces of the ceiling abutment portions are adjacent to the two adjacent ridges. When each of the stoppers is brought into contact with the lower end surface of the flange edge, the stopper comes into contact (or close proximity) to at least one of the outer edge and the inner edge of the two adjacent edge edges from at least one of the outer side and the inner side. Try to arrange in a state.

  In this case, for example, when the user leans against the column, or when the force is applied to the ceiling contact part through the column in a direction crossing the heel edge by pressing and pulling the column strongly The one stopper comes into contact with at least one of the outer edge and the inner edge of any one of the two adjacent brim edges to receive the force.

  This prevents the ceiling contact portion from moving from the lower end surfaces of the two adjacent ridges. As a result, as shown in FIG. 40, there is no possibility that one end portion of the ceiling contact portion collides with the ceiling plate between the two adjacent ridges and breaks the ceiling plate.

  Further, when the ceiling contact portion receives a force opposite to the direction of the force, the other stopper is at least one of the other outer edge and inner edge of the two adjacent brim edges. It will contact one side and receive the force. This prevents the ceiling contact portion from moving from the lower end surfaces of the two adjacent ridges.

  By the way, the upper surface of the ceiling contact portion is formed in a strip shape and the longitudinal dimension thereof is set to such a length as to cross over two adjacent ridges of the plurality of ridges, It is preferable that the stopper is a convex portion that is integrally provided so as to protrude upward along the entire length of the short side at both ends in the longitudinal direction of the ceiling contact portion.

  Here, the shape of the upper surface of the ceiling contact portion is specified, and the shapes and installation locations of the two stoppers are specified.

  In particular, since the longitudinal dimension of the strip-shaped ceiling contact portion is set to a length that crosses over two adjacent ridges, as described in the conventional example, Compared to a case where the length is set so as to cross over the heel edge, it is possible to reduce the manufacturing cost and weight of the ceiling contact portion. In addition, even when the support unit is installed close to the wall surface parallel to the flange, the support unit is excellent in terms of usability because the support unit does not travel greatly inside the room. Further, since the stopper has a simple convex shape, it can be formed relatively easily and inexpensively. This makes it possible to firmly install the ceiling contact portion on the rim ceiling without excessively increasing the longitudinal dimension.

  Further, the present invention is a column unit that is erected in a stretched state between a ceiling and a floor surface on which a plurality of flanges are provided, and a base installed on the floor surface, on the base A standing column, a ceiling contact portion attached to the upper end of the column, and a saddle adapter that is detachably mounted on the top surface of the ceiling contact portion. 2 adjacent to each other when they are located on at least one of the outer and inner sides of two adjacent ridges of the ridges, and the ceiling contact portion receives a force in a direction crossing the ridges. A stopper that abuts against at least one of the outer edge and the inner edge of any one of the book edges is provided.

  In this configuration, the ceiling abutting portion to which the saddle edge adapter is attached is attached to the ceiling abutting portion in such a posture as to cross over two adjacent saddle edges of the ceiling provided with the saddle edge. When the upper surface of the flange adapter is brought into contact with the lower end surfaces of the two adjacent flange edges, the stoppers are provided outside at least one of the outer edges and the inner edges of the two adjacent flange edges. And it arrange | positions in the state which contact | abutted (or adjoined) from at least one side inside.

  In this case, for example, when the user is leaning against the column, or when receiving a force in the direction crossing the heel edge at the ceiling contact part through the column, such as by grabbing the column and pushing or pulling strongly, The stopper of the flange adapter contacts the outer edge and / or the inner edge of one of the two adjacent flange edges to receive the force.

  As a result, it is possible to prevent the collar adapter and the ceiling contact portion from moving from the lower end surfaces of the two adjacent collars. As a result, as shown in FIG. 40, there is no possibility that one end portion of the ceiling contact portion collides with the ceiling plate between the two adjacent ridges and breaks the ceiling plate.

  Further, when the flange adapter and the ceiling contact portion receive a force in a direction opposite to the direction of the force, the other stopper is the other of the two adjacent flanges. The force is received by contacting at least one of the outer edge and the inner edge. This prevents the flange adapter and the ceiling contact portion from moving from the lower end surfaces of the two adjacent flanges.

  By the way, the collar adapter is formed in a strip shape, and its longitudinal dimension is set to such a length as to cross over two neighboring collars among the plurality of collars, and each of the stoppers. Are preferably convex portions that are integrally provided so as to protrude upward along the entire length of the short side at both ends in the longitudinal direction of the flange adapter.

  Here, the outer shape of the collar adapter is specified, and the shape and installation location of each stopper are specified.

  In particular, since the longitudinal dimension of the strip-shaped ceiling contact portion is set to a length that crosses over two adjacent ridges, as described in the conventional example, Compared to a case where the length is set so as to cross over the heel edge, it is possible to reduce the manufacturing cost and weight of the ceiling contact portion. Further, since the stopper has a simple convex shape, it can be formed relatively easily and inexpensively. This makes it possible to firmly install the ceiling contact portion on the rim ceiling without excessively increasing the longitudinal dimension.

  In addition, when the edge adapter is attached to the ceiling contact portion, it can be installed on the edge ceiling, and if the edge adapter is removed from the ceiling contact portion, it can be installed on a flat ceiling. Is possible.

  Moreover, it is preferable that the mutually opposing inner surface of each said stopper is made into the convex curved surface that the longitudinal direction center protrudes toward the other party.

  By the way, as for the ridged ceiling, generally, a type (hereinafter referred to as a wide ridged ceiling) and a small type (hereinafter referred to as a narrowed ridged ceiling) of the two adjacent edges are large. )

  Here, the stopper of the present invention is at least one of an outer stopper disposed on each outer side of two adjacent ridges and an inner stopper disposed on each inner side of two adjacent ridges. It is.

  First, when each of the stoppers is an outer stopper and the inner surfaces of the outer stoppers facing each other are convex curved surfaces, the maximum protruding position (longitudinal center) of the inner surface of one outer stopper and the other About the facing distance (shortest facing distance) with the maximum protruding position (longitudinal direction center) of the inner surface of the outer stopper, the same dimension as the dimension between the outer edges of the two adjacent ridges on the wide ridge ceiling, or If it is set to be slightly larger than the dimensions between the outer edges, for example, as shown in FIGS. 9 and 10, it is possible to cope with either the wide ridge ceiling or the narrow ridge ceiling. Become.

  On the other hand, when each of the stoppers is an inner stopper and the inner surfaces of the inner stoppers facing each other are convex curved surfaces, the facing distance between the outer surface of one inner stopper and the outer surface of the other inner stopper The (longest facing distance) is set to be the same as the dimension between the inner edges of the two adjacent ridges in the wide ridge ceiling, or smaller than the dimension between the inner edges, and one of the inner stoppers Adjacent at the narrow ridged ceiling, the facing distance (shortest facing distance) between the maximum protruding position (longitudinal center) of the inner surface and the maximum protruding position (longitudinal center) of the inner surface of the other inner stopper If it is set to be larger than the dimension between the outer edges of the two ridges, for example, as shown in FIGS. 22 and 23, the wide ridge ceiling and the narrow ridge ceiling may be of any type. It is possible to respond That.

  Furthermore, it is preferable that the said support | pillar is equipped with the operation mechanism which can adjust the full length in the middle of the longitudinal direction.

  In this configuration, it is possible to cope with a change in the facing distance between the ridged ceiling and the floor surface, so that the installation location of the column unit is not limited. In addition, since it is possible to adjust the degree of tension between the ridged ceiling and the floor surface, it is advantageous in firmly fixing the column unit.

  The column unit according to the present invention can be firmly installed so that the ceiling abutting portion does not move from the ridge edge of the ridge ceiling.

  BEST MODE FOR CARRYING OUT THE INVENTION Best modes for carrying out the present invention will be described in detail below with reference to the accompanying drawings.

  1 to 11 show an embodiment of the present invention. In the figure, 1 indicates the entire support unit.

  The column unit 1 includes a base 2, a column 3, a ceiling contact portion 4, a flange adapter 5, and the like.

  The base 2 is installed on the floor surface and is a rectangular plate. The base 2 is made of a metal excellent in load resistance and corrosion resistance, such as stainless steel, or a steel plate coated with a zinc (Zn) -aluminum (Al) -magnesium (Mg) alloy (plating, sputtering, etc.). Can do. It is also possible to form four corners of the base 2 in a round shape and attach a cushion (not shown) such as rubber to the outer peripheral edge of the base 2. Further, the base 2 may be a disc-shaped one made of synthetic resin, for example.

  At a predetermined position near the center of the base 2, a support column 2a is provided. The support column 2a can be formed separately from the base 2 and attached to the base 2 in an upright state by an appropriate method (for example, screwing or welding). It is also possible to form it. For example, both the base 2 and the support column 2a may be made of synthetic resin, and the base 2 and the support column 2a may be integrally formed.

  The support column 3 is erected on the base 2 and has a configuration in which the lower end portion of the upper small cylinder portion 3b is inserted into the upper end portion of the lower large cylinder portion 3a. The lower end portion of the lower large cylinder portion 3a is inserted into the column receiving cylinder 2a of the base 2, and the upper end portion of the upper small cylinder portion 3b is one of the three column insertion holes 4a of the ceiling contact portion 4 described below. Inserted into one.

  The lower large cylinder part 3a and the upper small cylinder part 3b can be made of, for example, a pipe made of aluminum or aluminum alloy covered with a semi-rigid resin or the like, or a metal such as stainless steel or an engineering plastic or the like. It can be made of a strong synthetic resin.

  The ceiling contact portion 4 is attached to the upper end of the column 3 and is in contact with the ceiling. The upper surface of the ceiling abutting portion 4 has an oval shape, that is, a belt-like shape and semicircular shapes at both ends in the longitudinal direction. The outer shape of the upper surface is gradually reduced toward the lower side.

  And the ceiling contact part 4 is formed with a suitable synthetic resin etc., The upper end of the upper small cylinder part 3b of the support | pillar 3 is inserted in several places (for example, 3 places) of the longitudinal direction so that removal is possible. A column insertion hole 4a is provided.

  The column insertion hole 4a is closed on the upper side and opened on the lower side, and has a cross-sectional shape of, for example, a hexagon. Correspondingly, the cross-sectional shape of the upper end portion of the upper small cylinder portion 3b is also formed in a hexagon. The reason why the cross-sectional shape is hexagonal is to prevent the upper small cylinder portion 3b of the column 3 and the column insertion hole 4a of the ceiling contact portion 4 from rotating relatively.

  Further, an operation mechanism 6 is provided at the upper end of the lower large cylinder portion 3 a of the support column 3. The operating mechanism 6 is provided to adjust the overall length dimension so that the support column 3 can be expanded and contracted.

  Specifically, the operating mechanism 6 is in a locked state in which the lower end of the upper small cylinder 3b is inserted into the upper end of the lower large cylinder 3a, and the upper small cylinder 3b is inserted into the lower large cylinder 3a. Switching to an unlocked state in which the depth can be changed, and the detailed configuration thereof is the same as that described in, for example, Japanese Patent Application Laid-Open No. 2014-051858. Omit.

  In the case of this operation mechanism 6, as shown in FIG. 1, the lever 6a can be brought into the locked state by performing an operation such that the lever 6a is brought close to the lower large cylinder portion 3a. On the other hand, as shown in FIG. When the lever 6a is operated to cause the lower large cylinder portion 3a to be in a horizontal posture, the unlocked state can be obtained.

  Here, an example of a method for assembling the support unit 1 will be briefly described. First, the lower end portion of the lower large cylinder portion 3 a of the column 3 is inserted into the column receiving cylinder 2 a of the base 2. And the upper small cylinder part 3b of the support | pillar 3 is inserted in the lower large cylinder part 3a of the support | pillar 3, and the ceiling contact part 4 is mounted | worn with the upper end part of this upper small cylinder part 3b.

  The collar adapter 5 is used when the column unit 1 is installed between the ceiling 10 provided with the collar 11 (hereinafter referred to as the collar ceiling) and the floor 20 as shown in FIG. It is a thing and is attached to the upper surface of the ceiling contact part 4 so that removal is possible.

  In other words, this saddle adapter 5 is installed between the floor surface 20 and the column unit 1 between the flat ceiling 30 (also referred to as a raised ceiling, hereinafter referred to as a flat ceiling) as shown in FIG. When it is done, it is removed from the upper surface of the ceiling contact portion 4.

  In the first place, in general, most Western-style ceilings have a flat surface, but Japanese-style ceilings have a plurality of ridges 11 so that they are uneven.

  The flange 11 is well-known, for example, is made of a wooden bar having a square cross-sectional shape, and is installed in parallel with each other. And the ceiling board 12 is arrange | positioned between each two adjacent ridges 11. The ceiling board 12 is made of, for example, a thin wooden board and is not supported on the back side of the rim ceiling 10, so that the strength is weak, and particularly, it is extremely weak against stress from below (inside the room).

  The flange adapter 5 is formed in a band plate shape, and is provided with a lattice-shaped rib 5b and a large number of meat stealing recesses 5c in the entire upper surface area of the bottom wall portion 5a, thereby reducing the weight and achieving a predetermined strength. Is configured to ensure.

  A buffer sheet 5d having a non-slip action is attached to both end regions in the longitudinal direction excluding the intermediate region in the longitudinal direction at the upper end edge of the rib 5b. As a result, the rib 5b and the meat stealing recess 5c in the intermediate region in the longitudinal direction of the rib adapter 5 are exposed, but the rib 5b and the meat stealing recess 5c in the longitudinal both ends of the rib adapter 5 are concealed. Although not shown in detail, the buffer sheet 5d is configured such that, for example, a sponge is used as a base and a buffer material such as rubber is bonded to one surface thereof.

  First and second outer stoppers 8 and 9 are integrally provided at both ends in the longitudinal direction of the flange adapter 5.

  Specifically, the first and second outer stoppers 8 and 9 are integrally provided on the upper part of both end portions in the longitudinal direction of the flange adapter 5, and are respectively provided on the outer sides of two adjacent flange edges 11 of the flange edge ceiling 10. Be placed.

  The first and second outer stoppers 8 and 9 are provided in the entire length range in the short direction of the flange adapter 5. The outer surfaces of the first and second outer stoppers 8 and 9 are formed in a linear shape, but the inner surface is a convex curved surface.

  The convex curved surface is a surface curved in a convex shape so that the center in the longitudinal direction of the first and second outer stoppers 8, 9, that is, the center in the short direction of the flange adapter 5 protrudes toward the other side. Yes, preferably a convex partial spherical surface. The curvature radius is appropriately set.

  On the lower surface of the bottom wall portion 5a of the flange adapter 5, a recessed portion 5e having a shape that can be fitted and fitted to the outer shape of the upper surface of the ceiling contact portion 4 is provided. A plurality of (for example, four) projecting pieces 5f projecting downward are provided at predetermined positions in the depressed portion 5e.

  The projecting piece 5f is substantially U-shaped in plan view, and is fitted into the meat stealing recess 4c of the ceiling contact portion 4 when the flange adapter 5 is attached to the ceiling contact portion 4. It has become. A number of meat stealing recesses 4c that are partitioned vertically and horizontally by lattice-like ribs 4b are provided in the middle region in the longitudinal direction of the upper surface of the ceiling contact portion 4.

  That is, in order to attach the flange adapter 5 to the ceiling contact portion 4, the recessed portion 5 e of the bottom wall portion 5 a of the flange adapter 5 is matched with the upper surface of the ceiling contact portion 4 and fitted to the ceiling contact portion 4. The four protrusions 5f of the collar adapter 5 may be fitted into the four meat stealing recesses 4c of the contact part 4. This restricts the movement of the flange adapter 5 relative to the ceiling abutting portion 4 and makes it non-separable. Thus, in order not to separate, the fitting state of the depressed portion 5e of the bottom wall portion 5a of the flange adapter 5 with respect to the upper surface of the ceiling contact portion 4 is set to a tight fit state.

  In order to obtain the tight fit state, two minute projecting portions 5g projecting toward each other are provided inside two opposing long sides in the recessed portion 5e of the collar adapter 5.

  In this way, by providing a total of four minute projecting portions 5g, the ceiling contact portion 4 and the edge adapter 5 are not separated, and the bottom wall portion of the edge adapter 5 is formed on the upper surface of the ceiling contact portion 4. When the recessed portion 5e of 5a is fitted or removed from the recessed portion 5e, it can be operated with a relatively weak force.

  Here, the configuration of the flange adapter 5 will be described in more detail. That is, the ceiling contact portion 4 to which the flange adapter 5 is attached has a posture in which the ceiling contact portion 4 crosses over the two adjacent flanges 11 of the flange ceiling 10 and the upper surface (buffer sheet 5d) thereof is adjacent to the two adjacent ones. The first and second outer stoppers 8 and 9 of the flange adapter 5 are applied to the outer edges of the two adjacent flange edges 11 from the outside. It is in a state of being placed in contact (or close proximity).

  In order to establish such a state, the facing distance between the maximum protruding position (longitudinal center) of the inner surface of the first outer stopper 8 and the maximum protruding position (longitudinal center) of the inner surface of the second outer stopper 9 ( The shortest facing interval) needs to be specified as described below.

  In general, the edge ceiling 10 has a type in which the distance between the two adjacent edges 11 is, for example, 500 mm (hereinafter, referred to as a wide edge ceiling), and a type, for example, 300 mm (hereinafter, referred to as a narrow edge). It is called an edge ceiling).

  In consideration of this, the shortest facing distance is the same as the dimension between the two outer edges of the two adjacent ridges 11 in the wide ridge ceiling 10 or slightly larger than the dimension between the respective outer edges (for example, 3mm to 10mm, preferably 5mm).

  With the flange adapter 5 set in this way, it is possible to respond so as to establish the above state regardless of the wide flange ceiling 10 or the narrow flange ceiling 10. It becomes possible.

  First, in the case of the wide ridge ceiling 10, as shown in FIG. 9, the longitudinal direction of the ceiling contact portion 4 to which the ridge adapter 5 is attached is aligned with the direction orthogonal to the longitudinal direction of the ridge 11. Then, when the collar adapter 5 is applied to the wide collar ceiling 10, the first and second outer stoppers 8, 9 of the collar adapter 5 abut against the outer edges of the two adjacent collars 11 from the outside. (Or close proximity).

  On the other hand, in the case of the narrow ridge ceiling 10, as shown in FIG. 10, the longitudinal direction of the ceiling contact portion 4 to which the ridge adapter 5 is attached is inclined with respect to the longitudinal direction of the ridge 11 by a predetermined angle. In this way, when the collar adapter 5 is applied to the narrow collar ceiling 10, one end in the longitudinal direction of the convex curved surface of the first outer stopper 8 of the collar adapter 5 corresponds to the two adjacent collars 11. The other end side in the longitudinal direction of the convex curved surface of the second outer stopper 9 is adjacent to the outer edge of one of the flanges 11 while coming into contact with (or close to) the outer edge. The two flanges 11 are arranged in such a manner that they contact (or approach) the outer edge of the other flange 11 from the outside.

  For this reason, the collar adapter 5 can be adapted regardless of the size of the distance between the two adjacent collars 11 (the dimension between each outer edge), and is therefore highly versatile. I can say that.

  In addition, if one of the two adjacent ridges 11 on the ridge ceiling 10 is constructed with a slight inclination as shown by a one-dot chain line or two-dot chain line in FIG. For convenience, the inclination of one of the collars 11 is exaggerated.) In the case where the inner surfaces of the first and second outer stoppers 8 and 9 are linear, the inclined collar 11 is inclined. In addition, since one of the first and second outer stoppers 8 and 9 interferes, the collar adapter 5 cannot be installed on the collar ceiling 10.

  However, even in such a case, if the inner side surfaces of the first and second outer stoppers 8 and 9 are convex curved surfaces as in the first embodiment, one end side in the longitudinal direction or the longitudinal direction of the convex curved surface. Since the other end is retracted outward, one of the first and second outer stoppers 8 and 9 does not interfere with the outer edge of the inclined flange 11. Thus, the said collar adapter 5 is excellent in usability, such as being able to absorb the malfunction in construction of the two adjacent collars 11.

  Next, an operation mode when installing the column unit 1 will be described.

  First, as shown in FIG. 8, the case where the support | pillar unit 1 is installed between the flat ceiling 30 and the floor surface 20 of a Western-style room is demonstrated. After the base 2 is installed at an appropriate position on the floor surface 20, the edge adapter 5 is not attached to the ceiling contact portion 4. Then, the operation mechanism 6 is unlocked, and the upper small cylinder part 3b is pulled up by a predetermined amount from the lower large cylinder part 3a, thereby bringing the upper surface of the ceiling contact part 4 into contact with the flat ceiling 30 with the surface. Thereafter, the operation mechanism 6 is brought into a locked state.

Subsequently, as shown in FIGS. 1, 6, and 7, a case where the column unit 1 is installed between the rim edge ceiling 10 and the floor surface 20 of the Japanese-style room will be described.
