Description

The present invention relates to a frame body attached to an opening of a building to support a closed body that opens and closes the opening formed in the building.

Conventionally, a frame is attached to an opening of the floor formed for an underfloor storage or an inspection port so that a lid that can open and close the opening can be stably supported and installed. I am trying to do it.

By the way, when this frame body is attached to the opening of the floor, the frame body is attached to the base material or joist of the floor as the attachment portion on the floor side by screws (see, for example, Patent Documents 1 and 2). However, when the frame is attached, the opening formed in the floor is covered with the flange of the frame, which makes it difficult to align the opening with the frame. Therefore, the flange of the frame is the surface of the floor. If it is not evenly applied to the floor, the frame may be damaged due to long-term use or a large load, and the amount of pressure of the airtight packing arranged on the back side of the flange of the frame may vary. There was a problem that the airtightness was lowered.

Hereinafter, embodiments of the frame for opening of a building of the present invention will be described with reference to the drawings.

1 to 7 show an embodiment in which the opening frame of the building of the present invention is applied to the floor opening frame.
The frame for the floor opening is the frame 1 attached to the opening Fo of the floor F in order to support a lid (not shown) as a closing body that openably closes the opening Fo formed in the floor F. By contacting the four corners of the outer periphery of the frame 1 with the inside corner surface Fi of the inner circumference of the opening Fo and urging the four corners of the outer circumference of the frame 1 toward the center, the opening Fo A corner member 2 as an alignment means for aligning the frame body 1 is arranged.

In this case, the frame body 1 can be made of a molded member made of a synthetic resin such as polypropylene resin.

Further, the corner member 2 has a main body so that the main body 21 and the main body 21 come into contact with the inner corner surface Fi (the inner corner surface of the floor F including the base material Fp and the joist J) on the inner circumference of the opening Fo. It is composed of a spring portion 22 that urges the portion 21 so as to appear and disappear in the radial direction.
In this embodiment, the corner member 2 is composed of an integrally molded member made of a synthetic resin such as a polyacetal resin, a polyamide resin, or a polycarbonate resin, which is integrally provided with a main body portion 21 and a spring portion 22.
Here, the main body 21 is chamfered on the upper and lower surfaces so that the slidability of the main body 21 with respect to the inside corner surface Fi is improved.
This makes it possible to simplify the configuration of the frame body 1 including the corner member 2, but the spring portion 22 of the corner member 2 can also be configured by, for example, another metal member.

Further, as shown in FIG. 5, among the storage portions of the corner member 2 provided in the frame body 1, the storage portion 15 of the spring portion 22 of the corner member 2 is placed on the back side of the storage portion 15 of the spring portion 22, that is, , The width is narrowed toward the center of the frame 1.
As a result, the urging force of the spring portion 22 of the corner member 2 is made constant regardless of the size of the opening Fo. Specifically, when the size of the opening Fo is small, it is compared with the case where it is large. Then, the amount of compression of the spring portion 22, that is, the urging force tends to increase, but the urging force is reduced by pushing the spring portion 22 into the narrowed portion, so that the opening Fo It can be made constant regardless of the size of the frame 1, whereby the workability at the time of attaching the frame 1 can be improved.

Further, the main body portion 21 and / or the spring portion 22 of the corner member 2 may be integrally formed with the frame body 1 by integral molding.

Then, the spring portion 22 of the corner member 2 automatically aligns the opening Fo and the frame 1 by fitting the frame 1 into the opening Fo formed in the floor F when the frame 1 is attached. To have the spring strength that is done in.
As a result, even if the opening Fo formed in the floor F is covered with the flange portion 11 of the frame body 1 during the mounting work of the frame body 1, the alignment of the opening portion Fo and the frame body 1 is automatically performed. , The flange portion 11 of the frame body 1 can be held in a state of being evenly hung on the surface of the floor F. By attaching to J with a screw (not shown) that is inserted into the screw hole 14 formed in the frame body 1, damage to the frame body 1 can be prevented, and the frame body 1 is arranged on the back side of the flange portion 11. The amount of pressure of the airtight packing 3 provided does not vary, and good airtightness can be maintained.
In this embodiment, the frame body 1 is attached to the mounting portion on the floor F side by screws, but a fixing means other than the screws is used or the screws are omitted, and the spring portion 22 of the corner member 2 is attached. It is also possible to fix the frame body 1 to the mounting portion on the floor F side only by the force.

Further, the frame body 1 has a circumferential groove portion 12 having a flat bottom surface on a circumferential step portion having a width of about 5 to 20 mm formed along the inner peripheral surface of the frame body 1 that supports the lid body. I try to form it.
On the inner peripheral side of the groove portion 12, a circumferential ridge portion 12a is formed so as to stand up by about 1 to several mm.
Here, at the top of the circumferential ridge portion 12a, an airtight packing (not shown) arranged on the bottom surface of the lid is pressed to ensure airtightness, and a circumferential groove portion having a flat bottom surface is provided. The lid is supported by 12.
As a result, the dust that has entered the gap between the frame body 1 and the lid body is received by the ridge portion 12a of the frame body 1, and the dust is placed in the box or under the floor of the underfloor storage (not shown) via the groove portion 12. It can be prevented from falling.

Further, the frame body 1 is provided with a flat bottom surface on a circumferential step portion having a width of about 5 to 20 mm formed along the inner peripheral side of the groove portion 12 of the frame body 1 that supports the box of the underfloor storage. The circumferential groove portion 13 is formed.
On the inner peripheral side of the groove portion 13, a circumferential ridge portion 13a is formed so as to stand up by about 1 to several mm.
The groove portion 13 and the ridge portion 13a are for supporting the box of the underfloor storage, and are covered with the edge of the box of the underfloor storage. It does not play a function of preventing dust that has entered the gap of the lid from falling into the box of the underfloor storage.

By the way, the corner member 2 as the alignment means aligns the frame 1 with respect to the opening Fo by urging the four corners of the outer periphery of the frame 1 toward the center. It is not limited to the above-described form, and is composed of, for example, a wedge-shaped corner member 2 arranged at the four corners of the outer periphery of the frame body 1 and having a wall thickness toward the lower side, as shown in FIG. You can also.
The corner member 2 is driven from below so that the driving dimensions of the four corner members 2 are even between the four corners of the outer circumference of the frame body 1 and the inside corner surface Fi of the inner circumference of the opening Fo. By arranging the frame body 1, the four corners of the outer periphery of the frame body 1 are biased (pressed) toward the center, and the frame body 1 is aligned with the opening Fo.
As a result, even if the opening Fo formed in the floor F is covered with the flange portion 11 of the frame 1 during the mounting work of the frame 1, the opening Fo and the frame 1 are aligned and the frame 1 is aligned. The flange portion 11 of the above can be held in a state of being evenly hung on the surface of the floor F. By attaching with a screw (not shown) inserted into the screw hole 14 formed in the body 1, it is possible to prevent the frame 1 from being damaged and to be airtightly arranged on the back side of the flange 11 of the frame 1. The pressing amount of the packing 3 does not vary, and good airtightness can be maintained.

Here, the four corner members 2 as the positioning means are not only configured independently, but can also be configured by being connected by an elastic connecting portion (not shown).
As a result, the corner member 2 and the connecting portion can be provided with the function of airtight packing on the outer circumference of the frame body 1 and the inner circumference of the opening Fo.

In addition, as the alignment means 2, one that aligns the frame 1 with respect to the opening Fo by urging the outer periphery of the frame 1 toward the center can be used.
Specifically, as shown in FIG. 9, the alignment means 2 has an annular elasticity made of silicone rubber or the like having a function of an airtight packing between the outer circumference of the frame 1 and the inner circumference of the opening Fo. It can also be composed of the member 23 and the reel members 24 arranged at the four corners of the outer periphery of the frame body 1.
Here, the reel member 24 preferably forms a spiral screw thread around a conical rotating shaft having a large diameter at the top, and uses the rotating shaft of one of the four reel members 24 as a driver or the like. By rotating with, the four reel members 24 are interlocked with each other via the elastic members 23 hung on the four reel members 24, and the elastic members 23 are formed on the outer periphery of the frame body 1 and the opening Fo. The four corners of the outer circumference of the frame 1 are pushed evenly between the inner circumferences and biased (pressed) toward the center of the outer circumference of the frame 1 to align the frame 1 with respect to the opening Fo. Is biased (pressed) toward the center to align the frame 1 with respect to the opening Fo.
As a result, even if the opening Fo formed in the floor F is covered with the flange portion 11 of the frame 1 during the mounting work of the frame 1, the opening Fo and the frame 1 are aligned and the frame 1 is aligned. The flange portion 11 of the above can be held in a state of being evenly hung on the surface of the floor F. By attaching with a screw (not shown) inserted into the screw hole 14 formed in the body 1, it is possible to prevent the frame 1 from being damaged and to be airtightly arranged on the back side of the flange 11 of the frame 1. The pressing amount of the packing 3 does not vary, and good airtightness can be maintained.
Here, since the annular elastic member 23 has the function of an airtight packing between the outer circumference of the frame body 1 and the inner circumference of the opening Fo, it is airtightly arranged on the back side of the flange portion 11 of the frame body 1. The packing 3 can be omitted.
Further, the reel member 24 has a spiral thread formed around a conical rotating shaft having a large diameter at the top, so that the annular elastic member 23 is lifted upward by the reel member 24. In the process of filling the gap between the outer circumference of the frame 1 and the inner circumference of the opening Fo, the action of pulling the frame 1 downward works, and the frame 1 can be attached along the floor F.

By the way, in the above embodiment, the alignment means 2 is biased toward the center of the outer periphery of the frame 1 to align the frame 1 with respect to the opening Fo. As described above, it is also possible to align the frame body 1 with respect to the opening Fo by urging the positioning means 2 with the inner circumference of the frame body 1 directed in the radial direction.

The frame for the floor opening is the frame 1 attached to the opening Fo of the floor F in order to support a lid (not shown) as a closing body for opening and closing the opening Fo formed in the floor F. , The four corners of the inner circumference of the frame body 1 are brought into contact with the opening Fo, specifically, the outer corner surface Fd of the outer circumference of the inner frame member Fu attached to the root thickness J, and the four corners of the inner circumference of the frame body 1 are contacted. By urging in the radial direction, the corner member 2 as the alignment means for aligning the frame 1 with respect to the opening Fo is arranged.

In this case, the corner member 2 urges the main body 21 so as to be able to appear and disappear in the central direction so as to abut the main body 21 and the outer corner surface Fd of the inner frame member Fu attached to the main body 21. It is composed of a spring portion 22.
In this embodiment, the corner member 2 is composed of an integrally molded member made of a synthetic resin such as a polyacetal resin, a polyamide resin, or a polycarbonate resin, which is integrally provided with a main body portion 21 and a spring portion 22.
Here, the main body 21 is chamfered on the upper and lower surfaces so that the slidability of the main body 21 with respect to the protruding corner surface Fd is improved.
This makes it possible to simplify the configuration of the frame body 1 including the corner member 2, but the spring portion 22 of the corner member 2 can also be configured by, for example, another metal member.

Further, as shown in FIG. 10, among the storage portions of the corner member 2 provided in the frame body 1, the storage portion 15 of the spring portion 22 of the corner member 2 is placed on the back side of the storage portion 15 of the spring portion 22, that is, , The width of the frame 1 is formed so as to be narrower in the radial direction.
As a result, the urging force of the spring portion 22 of the corner member 2 is made constant regardless of the size of the opening Fo. Specifically, when the size of the opening Fo is small, it is compared with the case where it is large. Then, the amount of compression of the spring portion 22, that is, the urging force tends to increase, but the urging force is reduced by pushing the spring portion 22 into the narrowed portion, so that the opening Fo It can be made constant regardless of the size of the frame 1, whereby the workability at the time of attaching the frame 1 can be improved.
