DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sill, and more particularly, to a sill installed between a Japanese-style room and a Western-style room adjacent to each other in a house so as not to have a step with the floor.

[0002]

2. Description of the Related Art As is well known, in a house considering the residence of the elderly and the disabled, it is necessary to prevent the elderly or the like from tripping over a threshold and to make it easy for a person to use a wheelchair. In addition, the upper surface of the sill installed between the adjacent Japanese-style room and the Western-style room or the like is made substantially flush with the floor surface so that no step is formed.

As shown in FIG. 8, as a conventional sill 31 of this kind, which is installed between adjacent Japanese-style rooms A and Western-style rooms B, for example, One in which a floor board fitting groove 4 for fitting an end of a floor board D is formed is known.

[0004] The sill main body 2 is made of glued laminated wood or wood having a long and rectangular cross section. When a sliding door is constructed above the sill 31, a hardwood (Moabi) 7 is buried approximately in the center of the upper surface 2 a of the sill main body 2. When the sill main body 2 is made of a material such as glued laminated wood, the appearance of which is not good, the upper surfaces 2a and 7a of the sill main body 2 and the hardwood 7 and the sill main body 2 are used to make the appearance beautiful. The single veneer 6 is attached to both side surfaces 2c and 2d. In this case, these veneer veneers 6 are attached in advance at a production plant or the like, but the upper corners 6b of both sides of the veneer body 2 and the veneer 6 attached to the upper surfaces 2a, 7a of the hardwood 7 are secured. For each of them, ear-cutting is performed.

[0005] After the sill 31 to which the veneer veneer 6 has been attached is conveyed to the construction site in this way, it opens upward on the upper surface 7a of the hardwood 7 to guide the sliding door.
The two sliding door grooves 3b are formed downward from the upper surface 6a of the veneer veneer 6, and the floor plate fitting groove 4 is formed on one side surface 2c of the sill main body 2 with the surface 6 of the veneer veneer 6.
It is formed from c to the side.

Here, the floor plate fitting groove 4 is provided with the floor plate D
The cross section is formed in a concave shape at a predetermined depth toward the side and with a groove width substantially equal to the thickness of the floor plate D so that the ends of the floor plate D can be fitted without a gap. Further, a rug material F such as a carpet is laid on the floor plate D.
In order to make the upper surface f of the rug material F substantially the same as the upper surface 6a of the veneer veneer 6, an interval of approximately the same dimension as the thickness of the rug material F is provided from the upper surface 6a of the veneer veneer 6. Formed. That is, the sum of the thickness C of the protruding portion 5 of the sill main body 2 formed above the floor plate fitting groove 4 and the thickness of the veneer veneer 6 is substantially the same as the thickness of the rug material F. Formed.

A tatami mat E is installed on the Japanese-style room A side of the sill 31 constructed as described above and installed at a predetermined position such that its upper surface e is substantially flush with the upper surface 6a of the above-mentioned single veneer 6. The western room B side is fitted with the floor plate fitting groove 4.
The floor plate D is installed so as to be fitted to the.

[0008] The thickness of the rug material F laid on the floorboard D thus installed is usually about 3 mm, and the shingle veneer 6 has a thickness of about 1 mm. Can be Therefore, in such a normal case, the thickness C of the projecting portion 5 is set to about 2 mm.

Further, as shown in FIG. 9, a sill 41 is installed at a higher position by using a plywood 8 or the like having a thickness of about 3 mm as a spacer, and the floor plate fitting groove 4 is formed at a lower position. As a result, the thickness C of the protrusion 5 is set to 5 mm.
It is also done to make it as large as possible.

Alternatively, as shown in FIG. 10, a floor board D is placed on a joist 9 without forming a floor board fitting groove 4 in the sill main body 2, and an end of the floor board D is attached to the above-mentioned plain wood veneer. Surface 6 of 6
A threshold 51 fixed so as to abut on c is also proposed.

Further, as disclosed in Japanese Utility Model Laid-Open Publication No. 7-4760, this is a threshold that is installed so that its upper surface is substantially flush with the floor surface, and is made of a metal material such as aluminum. Also, there has been proposed a sill in which a step portion for fitting an end portion of a floor plate to a lower surface of an end portion on a floor side is formed.
The sill is installed on the upper surface of a base material (sill main body) made of glued laminated lumber or wood having a long rectangular cross section and formed between the upper surface of the base material and the step portion. The end of the floorboard is fitted into the groove (floorboard fitting groove). In addition, two sill grooves (door sliding grooves) are formed on the upper surface of the sill, and sliding materials are attached to the bottoms of these sill grooves, respectively.

[0012]

However, in the conventional sill 31 as described above, the thickness C of the protruding portion 5 is normally as small as about 2 mm, and the strength of the single veneer 6 is high. Therefore, when the floor plate fitting groove 4 is formed or the end of the floor plate D is fitted into the floor plate fitting groove 4, there is a problem that the protruding portion 5 is easily chipped or cracked. is there. Therefore, there is a problem that it is necessary to pay close attention when performing these operations.
Further, if the floor board fitting groove 4 is formed in advance in the sill main body 2, the protrusion 5 may be chipped or cracked during transportation to the construction site. There is a problem that it can be formed only after transport. Further, there is a problem that the hardwood 7 used when constructing a sliding door such as a sliding door is difficult to obtain compared to other members.

Further, in the above-described threshold 41, the thickness C of the projection 5 is increased to about 5 mm, so that chipping or cracking is less likely to occur. Since the thickness is larger than the thickness of the material F, there is a problem that a step is generated between the threshold 41 and the Western room B.

Further, in the above-described threshold 51, since the cut edge at the end of the floorboard D is exposed on the surface, the appearance is not good, and after a long period of time, the baseboard D and the threshold 51 are shrunk by shrinkage of the groundwork. However, there is a problem that a gap may be generated.

In the threshold disclosed in the above publication, when an end of the floorboard is erroneously pushed into the groove by an excessive force, the floor is fixed to the upper surface of the base material from the groove. Since a force is applied to the sill to shift the sill to the side, there is a problem that the sill must be firmly fixed to the base material so that the sill does not fall off the base material. In addition, since this threshold is made of a metal material, the cost is higher than when using wood, plastic, or the like, and it is harder than these woods or the like, and the formation of the steps and the like is relatively difficult. There is a problem that it cannot be performed efficiently. Furthermore, in order to smoothly guide a sliding door such as a sliding door, it is necessary to attach a sliding material to the sill groove, so that it is difficult to reduce the cost.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and does not cause chipping or cracking in a protrusion of a sill main body formed above a floor plate fitting groove, thereby facilitating construction. It is another object of the present invention to provide a threshold that can be manufactured easily and reduce costs.

[0024]

Embodiments of the present invention will be described below with reference to the drawings. Note that the same components as those of the above-described conventional technology are denoted by the same reference numerals and description thereof is omitted.

First, a case where a sliding door is installed above a Japanese-style room A and a Western-style room B adjacent to each other in a house and constructed above the house will be described with reference to FIGS. As shown in FIG. 1, a threshold 1 according to the first embodiment includes a threshold main body 2,
And a plastic foam material 3 joined to the upper surface 2a of the sill main body 2.

The sill main body 2 has a long shape and a rectangular cross section, and may be made of laminated wood or wood.

The plastic foam material 3 is formed of a plastic foam formed in a plate shape which is long and substantially the same width as the width of the sill main body 2. The plastic foam material 3 is bonded to the upper surface 2a of the sill main body 2 with an adhesive or the like as described above, and has two sliding door grooves that open upward and guide the sliding door on the upper surface 3a. 3b are respectively formed. In addition, this door sliding groove 3
The number of b is not limited to two, and an appropriate number may be formed according to the type of sliding door to be constructed. Also,
As a foam constituting the plastic foam material 3, various plastic foams such as polyvinyl chloride and polystyrene can be used.
1.2 to 2.5 times is desirable, and 1.5 to 2.0 times is more preferable. Further, in this embodiment, the plastic foam material 3 is formed integrally, but it can also be formed by joining a plurality of plate members in the lateral direction.

The same side surfaces 2c, 3c of the sill main body 2 and the plastic foam material 3 are provided on the sill main body 2 and the plastic foam material 3, respectively.
And a floor board fitting groove 4 for fitting the end of the floor board D over both of the plastic foam material 3. Further, a protruding portion 5 having a thickness C is formed above the floor plate fitting groove 4. The thickness C is substantially the same as the thickness of the rug material F laid on the floor plate D. It may be a little smaller. That is, the thickness of the rug material F is 3 m.
m, the thickness C of the protruding portion 5 is set to 2 to 3
mm may be used.

Here, when the sill main body 2 is made of laminated wood or the like and the appearance is not good, in order to make the appearance beautiful, the upper surface 3a of the plastic foam material 3 and
Both sides 2c, 3 of the sill body 2 and the plastic foam material 3
A single veneer 6 can be attached to each of c, 2d, and 3d. In this case, if a colorant is added during the production of the plastic foam material 3 so that the color is the same as the color of the veneer veneer 6, as in this embodiment, the sill main body 2 is provided.
In addition, the single wood veneer 6 to be attached to the side surfaces 2c, 3c of the plastic foam material 3 can be dispensed with. In addition, it is possible to dispense with the single wood veneer 6 attached to the upper surface 3a of the plastic foam material 3. Is desirable. As described above, if the single wood veneer 6 is used, inexpensive materials such as glued laminated timber can be used for the sill main body 2, so that the cost can be reduced.

Next, a method for manufacturing the above-described threshold 1 will be described with reference to FIGS. To manufacture the sill 1, as shown in FIG. 2, first, a plastic foam material 3 is bonded to the upper surface 2 a of the sill main body 2 with an adhesive or the like. In this case, the color of the plastic foam material 3 may be the same as the color of the single veneer 6 by adding a coloring agent in advance at the time of manufacture as described above.

After the plastic foam material 3 has been joined to the upper surface 2a of the sill main body 2 as described above, as shown in FIG. The board 6 is adhered to the sill main body 2 and the other side surfaces 2d and 3d of the plastic foam material 3 with an adhesive, and then another plain wood veneer 6 is adhered to the upper surface 3a of the plastic foam material 3 with an adhesive. As shown in FIG. 4, it is desirable that the upper corners 6 b of both sides of the veneer 6 attached to the upper surface 3 a of the plastic foam material 3 be trimmed for safety.

Further, as shown in FIG. 5, two sliding door grooves 3 opening upward are formed on the upper surface 3a of the plastic foam material 3.
b is formed from the upper surface 6a of the single veneer 6 and one side 2 of the sill main body 2 and the plastic foam material 3.
A floor plate fitting groove 4 extending over both the sill main body 2 and the plastic foam material 3 is formed in c and 3c. In this case, when laying the rug material F having a thickness of about 3 mm on the floorboard D, a gap of about 3 mm from the upper surface 6a of the veneer 6 and a distance of about 2 mm from the upper surface 3a of the plastic foam material 3 are provided. The floor plate fitting groove 4 may be formed.

On the side of the Japanese-style room A of the sill 1 constructed as described above and installed at a predetermined position, the upper surface e thereof is substantially flush with the upper surface 6a of the single veneer 6 as shown in FIG. The tatami mat E is thus installed, and the floor board D is installed on the Western room B side such that its end is fitted into the floor board fitting groove 4.

Here, the floor plate fitting groove 4 is provided in the sill main body 2.
And the plastic foam material 3, the front end face d of the end of the floor plate D is applied to both the sill body 2 and the plastic foam material 3 at the back wall 4 d of the floor plate fitting groove 4. Touch Therefore, even if the end of the floorboard D is erroneously pushed into the floorboard fitting groove 4 by excessive force,
There is no intensive force acting on the plastic foam material 3 to shift it to the side. Therefore, the joining strength between the plastic foam material 3 and the sill main body 2 does not need to be particularly high, so that the plastic foam material 3 can be easily joined to the sill main body 2. in this case,
If the sill 1 is manufactured in advance in a production factory or the like as described above, the construction can be shortened.

Further, since the glued laminated lumber or wood constituting the sill main body 2 and the plastic foamed material 3 are inexpensive, the cost can be reduced. And
Since the sill main body 2 and the plastic foam material 3 are soft members as compared with the metal material, the floor board fitting groove 4 is used.
Is also easy to form. From the above, the sill 1 including the sill main body 2 and the plastic foam material 3 can be manufactured easily and at low cost.

Further, even when the thickness C of the projecting portion 5 is as small as about 2 mm as described above, since the projecting portion 5 is a part of the plastic foam material 3, stress or impact is applied here. There is an advantage that chipping or cracking hardly occurs even when it acts. Therefore, plastic foam 3
The floor plate fitting groove 4 can be formed in advance,
Also, at the construction site, the end of the floorboard D can be easily fitted into the floorboard fitting groove 4 without paying close attention.

The floor plate D is connected to the floor plate fitting groove 4 at its end.
The end of the floorboard D is not exposed to the surface, and a gap is generated between the floorboard D and the sill 1 even if the base material shrinks after a long period of time. Never.

In the case of using the single veneer 6 as in this embodiment, the sum of the thickness C of the protruding portion 5 and the thickness of the single veneer 6 is defined as the thickness of the rug F. If they are substantially the same, there will be no step between the threshold 1 and the Western room B.

If the sill main body 2 is made of wood or the like having a beautiful appearance and a colorant is added during the production of the plastic foam material 3 so that the color of the sill main body 2 is the same as that of the sill main body 2, Since the overall appearance is the same color as a whole, the above-mentioned shingle veneer 6 can be unnecessary. However, as described above, for protection of the plastic foam material 3,
On the upper surface 3a of the plastic foam material 3, a single veneer 6
It is desirable to affix it.

Next, a case where the door is installed between the Japanese-style room A and the Western-style room B and a door is constructed above the room is described with reference to FIGS. As shown in FIG. 6, the sill 11 according to the second embodiment is substantially the same as the above-described first embodiment, but is configured without forming the sliding door groove 3b.

The threshold 11 can be manufactured by the same steps as those shown in FIGS. 2 to 5 in the first embodiment.
In the step shown in FIG. 5, only the floor plate fitting groove 4 may be formed without forming the sliding door groove 3b. As described above, since the manufacturing process can be shared between the case where the sliding door such as the sliding door is constructed and the case where the swing door is constructed, the increase in cost can be suppressed.

As shown in FIG. 7, the sill 21 according to the third embodiment has a structure in which the height of the sill main body 2 is increased, the thickness of the plastic foam material 3 is reduced, and the floor plate fitting groove 4 is provided. Is formed on the upper edge 2 e of one side surface 2 c of the sill main body 2.

In the sill 21, the thickness of the plastic foam material 3 joined to the upper surface 2 a of the sill main body 2 becomes the thickness C of the protrusion 5 formed above the floor plate fitting groove 4. The thickness of the plastic foam material 3 may be approximately the same as or slightly smaller than the thickness of the rug material F. If the floor board fitting groove 4 is formed in the upper end edge 2e of the one side surface 2c of the sill main body 2 in this manner, the front end face d of the end of the floor board D will become the inner wall 4d of the floor board fitting groove 4. Abuts only on the sill body 2 at this time.
Even if the end of the plastic foam material 3 is erroneously pushed with an excessive force, the plastic foam material 3 hardly receives a force to shift to the side. Therefore, the joining strength between the plastic foam material 3 and the sill main body 2 does not need to be particularly high, and therefore the sill main body 2 of the plastic foam material 3 is not required.
Can be easily joined. Further, the sill main body 2 is made of laminated wood or wood, and is a soft member as compared with a metal material.
Is also easy to form.

The case where the thresholds 1, 11, 21 are set between the adjacent Japanese-style room A and the Western-style room B has been described above.
The present invention is not limited to this, and may be installed between the adjacent corridor and the Western room B, or between the adjacent Western rooms B and the like. Western-style room B adjacent to thresholds 1, 11, 21
In the case where the sill main body 2 and the plastic foam material 3 are installed between each other, both side surfaces 2c, 3c and 2d, 3d,
Alternatively, the floor plate fitting grooves 4 may be formed in the upper edge portions 2e on both sides of the sill main body 2 as described above.

[0045]

As described above, according to the sill of claim 1, the sill main body and the plastic foam material bonded to the upper surface of the sill main body are provided, and the upper end edge of the side surface of the sill main body is provided.
By forming a floor plate fitting groove in the portion, the end of the floor plate
When the end of the floorboard is accidentally pushed by excessive force into this floorboard fitting groove, the tip surface of the part is made to contact only the sill body at the back wall of the floorboard fitting groove. But, wherein the plastic foam, force to Zureyo laterally photo
Has little effect. Therefore, the joining strength between the plastic foam material and the sill main body does not need to be particularly high, so that the plastic foam material can be easily joined to the sill main body.

Also, glued timber, wood, or the like constituting the sill main body or plastic foam is inexpensive.
Cost can be reduced. Further, since the sill main body and the plastic foam material are soft members as compared with the metal material, the floor plate fitting groove can be easily formed. As described above, the sill including the sill main body and the plastic foam material can be manufactured easily and at low cost.

Further, since the protrusion formed above the floor plate fitting groove is a part of a plastic foam material, chipping or cracking hardly occurs even when stress or impact acts on the protrusion. There are advantages. Therefore, before the sill is transported to the construction site, the floor plate fitting groove can be formed in advance in a production factory or the like. Further, at the time of construction, the floor plate fitting groove can be formed without paying close attention to the floor plate fitting groove. Since the parts can be fitted easily, the construction can be shortened.

In addition, since the floor plate is installed with its end fitted into the floor plate fitting groove, the end of this floor plate is not exposed on the surface. Even if the base material shrinks after a long period of time, there is no gap between the floorboard and the sill, and the appearance is maintained in a good condition.

[0049]

Further, by making the thickness of the plastic foam material substantially the same as or slightly smaller than the thickness of the rug material laid on the floorboard, the upper surface of the rug material becomes the upper surface of the plastic foam material or the plastic foam material. Since it is made to be substantially flush with the upper surface of the single veneer glued on the timber, there is no step between the threshold and the Western room. Sa
In addition, plastic foam without floor plate mating grooves
Can be used as is to produce a threshold.

According to the second aspect of the present invention, the appearance of the sill can be made beautiful by sticking a single veneer on at least the top surface of the plastic foam material. It can be used and cost can be reduced.

According to the third aspect of the present invention, the appearance of the sill is made the same color as a whole by adding a colorant to the plastic foam material to make the same color as the color of the sill main body. The necessity of a single piece of white wood can be eliminated, and manufacturing can be shortened.

According to the sill of claim 4 , since a colorant is added to the plastic foam material so that the color is the same as the color of the single veneer, the sill body and the plastic foam material forming the floor board fitting groove are provided. It is possible to eliminate the need for a single veneer to be attached to the same side surface, and to shorten the production.

According to the sill of claim 5 , since at least one sliding door groove which opens upward is formed on the upper surface of the plastic foam material, a sliding door such as a sliding door is constructed above the sill. it can. Further, since the sliding door groove can be formed in the plastic foam material itself, conventional hardwood is unnecessary, and since plastic foam material can be mass-produced, material procurement is easy. Furthermore, since this plastic foam material has a smooth surface and excellent wear resistance, there is no need to attach a sliding material or the like to the bottom of the sliding door groove. In addition, in the case of using a single veneer as described above, if the color of the plastic foam material is set to the same color as that of the single veneer, even if the sliding door is opened and the sliding door groove is exposed on the surface, The appearance of this sliding door groove is also beautiful because it has the same color as the plain wood veneer.
