Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underfloor storage in which a storage container is arranged under the floor of a kitchen or the like. 2. Description of the Related Art In order to efficiently store large bottles and cans of seasonings, underfloor storage is often provided under the floor of a kitchen or the like. In this underfloor storage, for example, as shown in FIG. 8, a floor material 4 is opened between joists 5 and 5, a shell main body 2 which is a storage container made of synthetic resin is arranged in the opening hole, and the opening is formed. Is covered with the lid material 3. The shell main body 2 is supported by the receiving frame 1 fitted into the opening of the flooring 4 at its peripheral edge, and is accommodated in the opening. The lid 3 is supported by the upper end of the peripheral edge of the shell body 2 to close the opening of the floor 4, and is arranged such that the upper surface of the lid 3 is flush with the upper surface of the floor 4. The cover 3 may be directly supported by the receiving frame 1. In the underfloor storage having the above structure, the lid 3 is lifted by a handle (not shown) or, for example, the lid 3 is lifted.
By folding it in half and sliding it to one end
The upper part of the shell main body 2 is opened, and stored articles can be taken in and out through this opening. Also, if the opening is closed again with the lid member 3, the floor surface can be configured together with the floor member 4.
It does not occupy the kitchen space and the like. FIG. 9 shows details of the vicinity of the opening end of the floor material 4 in the above-mentioned conventional underfloor storage. The receiving frame 1 has a fitting portion 1a fitted into the opening of the floor material 4, and a flange-shaped floor material locking portion 1b protruding on the outer peripheral side is provided at the upper end of the fitting portion 1a. A shelf-shaped main body supporting portion 1h protruding from the lower end of the fitting portion 1a to the inner peripheral side.
Is provided. The floor material locking portion 1b is locked on the peripheral edge of the opening of the floor material 4, and covers the opening end of the floor material 4 so as not to be exposed to the floor surface. In addition, the main body supporting portion 1h supports the upper end peripheral portion 2a of the shell main body 2 in a mounted manner. In the receiving frame 1, the main body supporting portion 1 h is placed and supported on an auxiliary joist 6 fixed to a side surface of the joist 5 by a wood screw 7, and is fixed to the auxiliary joist 6 by a wood screw 9. The lid member 3 is covered at its peripheral edge with an aluminum lid frame 12, is fitted into the inner periphery of the fitting portion 1 a of the receiving frame 1, and is placed and supported on the upper peripheral edge portion 2 a of the shell main body 2. However, it is unavoidable that a gap is formed between the upper peripheral portion 2a of the shell main body 2 and the main body supporting portion 1h of the receiving frame 1 due to the distortion of the shell main body 2 and the receiving frame 1. . Therefore, the outside air under the floor may enter the room through the gap between the fitting portion 1a of the receiving frame 1 and the lid frame 12 of the lid member 3 along the route of the arrow A shown in FIG. In addition, since a gap may be formed between the floor material locking portion 1b of the receiving frame 1 and the peripheral edge of the opening of the floor material 4 due to the distortion of the receiving frame 1 and the floor material 4, a path indicated by an arrow B shown in FIG. And the outside air under the floor may enter the room. For this reason, in the conventional underfloor storage, the outside air enters through the gap between the receiving frame 1 and the lid member 3 or the gap between the receiving frame 1 and the floor member 4, so that the airtightness in the room is reduced and the air conditioning efficiency is reduced. In addition, there has been a problem that the feet become cold easily, especially in winter. SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to provide an underfloor compartment in which outside air does not enter from under the floor by closing a gap between a receiving frame and a cover or floor with packing. . [0008] In order to solve the above problems, the underfloor storage according to the present invention has a fitting portion of an aluminum receiving frame fitted into an inner periphery of an opening of a floor material, and the fitting portion of the aluminum receiving frame is fitted. A flange-shaped floor material locking portion projecting outward from the upper end of the joint portion is locked on the opening peripheral portion of the floor material via elastic floor material packing, and the fitting portion A peripheral portion of the lid material that covers the opening of the flooring material is supported on a lid material supporting portion protruding from the lower portion to the inner peripheral side, and a bulge that rises upward on the inner peripheral side and the outer peripheral side. An elastic lid packing having a portion is inserted into a groove formed on an upper surface of the lid support portion in a state where the tip of the raised portion is urged against the lower surface of the peripheral portion of the lid, and A shell main body disposed in an opening hole of the floor material in a shelf-shaped main body support portion projecting from the lower side of the lid material support portion to the inner peripheral side; Is supported at the periphery thereof. [0010] Further, the lid packing has a raised portion which is raised upward at substantially the same height on the inner peripheral side and the outer peripheral side, and the raised part is provided between the inner peripheral side and the outer peripheral side. A small raised portion that is raised at a height lower than the height of the portion. Further, the lid packing is made of a rubber foam of ethylene propylene. [0012] According to the above construction, the gap between the receiving frame and the flooring material is sealed by the flooring packing, so that outside air that tries to enter the room from under the floor through the space between the receiving frame and the flooring material can be prevented. Can be shut off. In addition, since the gap between the receiving frame and the lid member is also sealed by the lid material packing, it is possible to block the outside air that tries to enter the room through the space between the receiving frame and the lid member. Moreover, since the tip of the raised portion on the inner peripheral side and the outer peripheral side is pressed against the lower surface of the peripheral portion of the lid material, the gap between the receiving frame and the lid material can be double-blocked, This gap can be reliably sealed each time the lid is repeatedly opened and closed. In the case where a small raised portion is provided between the inner circumferential side and the outer circumferential side of the lid packing, the tip of the raised portion is pressed against the lower surface of the peripheral portion of the lid and crushed. In this state, the tip of the small protrusion can be brought into contact with the lower surface of the peripheral portion of the lid, so that the gap between the receiving frame and the lid can be more reliably closed. . Further, if the lid material packing is formed of a rubber foam of ethylene propylene, it can be tightly adhered to the lower surface of the peripheral portion of the lid material by soft elasticity, and the gap can be reliably sealed.
It has sufficient resistance to repeated pressing. Embodiments of the present invention will be described below in detail with reference to the drawings. FIGS. 1 to 7 show an embodiment of the present invention. FIG. 1 is a longitudinal sectional view showing a structure of an underfloor storage near an opening end of a floor material, and FIG. FIG. 3 is a longitudinal sectional view showing an assembled state of the underfloor compartment near the end, FIG. 3 is a longitudinal sectional view showing a state where the underfloor compartment is opened near the opening end of the floor material, and FIG. 5, FIG. 5 is a rear view of the lid packing of FIG. 4, FIG. 6 is a longitudinal sectional view showing another shape of the lid packing, and FIG. 7 is a floor using the lid packing of FIG. FIG. 3 is a partially enlarged longitudinal sectional view near an opening end of a material. Components having the same functions as those of the conventional example shown in FIGS. 8 and 9 are denoted by the same reference numerals. As shown in FIG. 1, the underfloor storage according to the present embodiment includes a receiving frame 1, a shell body 2, and a lid 3, and is disposed at an opening of the floor 4. The receiving frame 1 is a frame made of aluminum and has a side wall-shaped fitting portion 1 a fitted into the opening of the flooring 4. That is, for example, when the opening of the flooring material 4 is rectangular, the fitting portion 1a also has a rectangular side wall-like frame slightly smaller than the opening of the flooring material 4. At the upper end of the fitting portion 1a, a flange-shaped floor material locking portion 1b projecting from the outer peripheral side is provided. In addition, a concave portion 1c is formed on the lower surface of the floor material locking portion 1b, as shown in FIG. Therefore, when the receiving frame 1 is fitted into the opening of the floor material 4, only the lower end on the outer peripheral side of the floor material locking portion 1 b abuts and locks on the peripheral edge of the opening of the floor material 4. At the lower end of the fitting portion 1a of the receiving frame 1, there is provided a lid supporting portion 1d projecting from the inner peripheral side. A groove 1e is formed in the lid supporting portion 1d along the longitudinal direction of the receiving frame 1. In addition, the lid supporting portion 1
From the lower surface of d, leg portions 1f and 1g are protruded downward on the inner peripheral side and the outer peripheral side, respectively. In addition, a shelf-shaped main body supporting portion 1h protruding further on the inner peripheral side is provided at the lower end of the inner peripheral side leg portion 1f. An auxiliary joist 6 is fixed by a wood screw 7 to the inner peripheral side surface of the joist 5 that supports the periphery of the opening of the flooring material 4 from under the floor. In the receiving frame 1, the fitting portion 1 a is inserted into the opening of the floor material 4, and the lower end on the outer peripheral side of the floor material locking portion 1 b is placed on the peripheral edge of the opening of the floor material 4 as shown in FIG. At the same time, the lower surfaces of the legs 1f and 1g and the main body supporting portion 1h abut on the auxiliary joist 6. The receiving frame 1 is fixed on the auxiliary joist 6 by a wood screw 9 screwed from above the groove 1e. As shown in FIG. 2, a flat floor material made of a rubber foam of ethylene propylene (EPDM) is provided between the floor material engaging portion 1b of the receiving frame 1 and the peripheral edge of the opening of the floor material 4. The packing 8 is intervened. Therefore, as shown in FIGS. 1 and 3, when the lower end on the outer peripheral side of the floor material locking portion 1 b abuts on the opening peripheral edge of the floor material 4, the floor material packing 8 is moved to the concave portion 1 c.
The gap between the receiving frame 1 and the peripheral edge of the opening of the flooring material 4 can be sealed by being pressed. A lid packing 10 made of the same ethylene propylene rubber foam as the floor packing 8 is fitted into the groove 1e of the receiving frame 1. This lid packing 10
As shown in FIG. 4, raised portions 10b, 10b, which are raised sufficiently higher than the depth of the groove portion 1e of the receiving frame 1 upward, are provided on the inner peripheral side and the outer peripheral side of the upper surface of the flat base 10a, respectively. Is provided. As shown in FIGS. 4 and 5, a gap is provided on the lower surface of the base 10a of the lid packing 10 so as not to protrude from both sides.
Is attached. Therefore, this lid packing 10
Can be inserted into the groove 1e of the receiving frame 1 by first peeling off the release paper of the double-sided tape 11 and pressing the lower surface of the base 10a against the bottom surface of the groove 1e of the receiving frame 1. The shell body 2 shown in FIGS. 1 and 3 is a storage container made of a synthetic resin having a certain degree of rigidity. The upper end protrudes to the outer peripheral side and the outer peripheral end is folded downward. Is provided. Then, the shell main body 2 is inserted into the opening hole of the flooring material 4, and the upper peripheral edge 2 a is placed and supported on the main body support 1 h of the receiving frame 1. The cover member 3 is a plate member having a pattern similar to that of the floor member 4 on the upper surface, and a lid frame 12 whose peripheral portion is made of aluminum.
Covered with. Then, as shown in FIG. 3, it is fitted into the inner periphery of the fitting portion 1a of the receiving frame 1 in the opening of the flooring material 4, and as shown in FIG. It is placed and supported on the periphery. At this time, the tip of the raised portions 10b, 10b of the lid packing 10 inserted into the groove 1e is pressed against the lower surface of the lid frame 12 of the lid 3 and is crushed on the outer peripheral side and the inner peripheral side, respectively. Therefore, the gap between them can be double-sealed. In addition, lid material 3
When the is lifted, as shown in FIG. 3, the tips of these raised portions 10b return to the state of being raised again by elasticity. When the ridges 10b, 10b are formed on the upper surface of the lid packing 10, the ridges 10b, 10b, 10b, 10b may be slightly lifted even when the lid 3 is partially lifted up by a part of the receiving frame 1 or the lid 3. The relatively flexible distal end portion 10b easily follows the change in the height position of the lower surface of the lid frame 12 and can be tightly sealed. In addition, since these raised portions 10b, 10b are formed to protrude from the base 10a of the lid packing 10, the lid 3
The seal can be firmly adhered to the lower surface of the lid frame 12 sufficiently, and sufficient durability against repeated pressing can be obtained. According to the underfloor storage having the above-described structure, the gap between the receiving frame 1 and the floor material 4 is sealed by the floor material packing 8, and the gap between the receiving frame 1 and the lid material 3 is also covered by the lid packing 10. Since the inner and outer ridges 10b, 10b are double-sealed, it is possible to reliably block outside air from entering the room from under the floor. Also, when the lid member 3 is repeatedly opened and closed, the ridges 10b,
10b is pressed against the lower surface of the lid frame 12 each time, so that the gap can be reliably sealed. Further, since the base 10a of the lid packing 10 hides the head of the wood screw 9 screwed into the groove 1e of the receiving frame 1, the head of the wood screw 9 is exposed when the lid 3 is opened. The appearance can be prevented from being deteriorated. FIGS. 6 and 7 show other examples of the structure of the lid packing 10. FIG. This lid packing 10 is also made of a rubber foam of ethylene propylene similarly to the one shown in FIG.
As shown in FIG. 6, on the inner peripheral side and the outer peripheral side of the upper surface of the flat base 10a, there are provided raised portions 10b, 10b which are raised sufficiently higher and higher than the depth of the groove 1e of the receiving frame 1 respectively. ing. Moreover, these raised portions 10b, 10
A small protruding portion 10c that protrudes upward to a degree slightly higher than the depth of the groove portion 1e of the receiving frame 1 is provided between the small protruding portions 10b. Then, the lid packing 10 is also fitted and fixed in the groove 1e of the receiving frame 1 by the double-sided tape 11 on the lower surface of the base 10a. As shown in FIG. 7, the cover 3 is fitted into the inner periphery of the fitting portion 1a of the receiving frame 1, and the lower surface of the cover frame 12 is
d, the distal ends of the ridges 10b, 10b of the lid packing 10 inserted into the groove 1e are pressed against the lower surface of the lid frame 12, and are respectively placed on the outer and inner peripheral sides. And the gap between them can be sealed. At this time, these raised portions 10
The tips of the small raised portions 10c, which are slightly lower than b and 10b, also come into contact with the lower surface of the lid frame 12 and are slightly pressed. Therefore, when the lid packing 10 is used, the gap between the receiving frame 1 and the lid member 3 is closed three times by the tip of the small raised portion 10c in addition to the raised portions 10b, 10b, and further securely sealed. Will be able to In the above embodiment, the floor packing 8 is used.
Although the rubber material of the lid and the packing material 10 is made of a rubber foam of ethylene propylene, another rubber foam may be used, or a synthetic resin foam such as a soft foam of polyvinyl chloride may be used. As is apparent from the above description, according to the underfloor storage of the present invention, the gap between the receiving frame and the floor material or the lid material is reliably formed by the floor material packing and the lid material packing. Since it is sealed, the outside air from under the floor can be shut off to improve the airtightness of the room, and the air conditioning efficiency does not decrease and the feet do not cool down in winter.
