Abstract

PROBLEM TO BE SOLVED: To enable both a heat insulating effect and a convenience in use to be satisfied concurrently by a method wherein an inner lid having a thermal insulating characteristic is arranged between a main body of the storing device and an outer lid and the inner lid is formed into a substantial pyramid shape as viewed from a side surface. SOLUTION: An inner lid 5 having a thermal insulating characteristic is arranged between a main body 2 of a storing device and an outer lid 4 for opening or closing the main body 2 of the storing device and the inner lid 5 is formed into a substantial pyramid shape as viewed from a side surface. One of either an upper edge 5a or a lower edge 5b of the inner lid 5 is resiliently contacted with an inner circumferential surface 2a of the main body 2 of the storing device. With such an arrangement as above, when the inner lid 5 is opened or closed, since a contact area between the inner lid 5 formed into a substantial pyramid shape as viewed from the side surface and the inner circumferential surface 2a of the main body 2 of the storing device is narrow, a frictional force between both members is reduced and the inner lid 5 can be smoothly opened or closed without any resistance together with the outer lid 4. In addition, an air-tightness between the inner lid 5 and the main body 2 of the storing device can be assured and then a cold air can be prevented from being transmitted toward an inner side even at a cold district.

However, since the conventional heat insulating lid is fitted and supported in the storage opening of the storage, it is necessary to perform both the operation of opening and closing the outer lid and the operation of opening and closing the heat insulating lid. However, there is a problem that the usability of the storage cabinet is deteriorated. In particular, in order to improve the airtightness of the heat insulating lid, if the gap between the heat insulating lid and the storage is eliminated, it becomes difficult to open and close the heat insulating lid, and as a result, in the conventional technology, ensuring the airtightness of the heat insulating lid, It was not possible to satisfy both of the simplification of opening and closing the heat insulating lid at the same time.

The present invention has been made in view of the above points, and it is an object of the present invention to prevent cold air from being transmitted to a room even in a cold region by an inner lid having a heat insulating property and to open and close the inner lid. It is to provide an underfloor storage that enables both the heat insulation effect and the usability to be satisfied at the same time.

With this configuration, when the inner lid 5 is opened and closed, the inner lid 5 formed in a substantially trapezoidal shape when viewed from the side and the inner peripheral surface 2a of the storage case body 2 come into contact with each other. Since the area is small, the frictional force between the two becomes small, the inner lid 5 can be smoothly opened and closed together with the outer lid 4 without resistance, and the airtightness between the inner lid 5 and the storage main body 2 is ensured. It is possible to prevent the transmission of cold air into the room even in cold regions.

Here, the inner lid 5 is provided on the lower surface 4a side of the outer lid 4.

By this, the airtightness between the outer peripheral surface 2b of the storage case main body 2 and the floor opening 6 can be secured, and together with the heat insulation effect of the inner lid 5 elastically contacting the inner peripheral surface 2a of the storage case main body 2, the underfloor storage case 1
The overall heat insulating property can be improved.

Further, the inner peripheral surface 2a of the storage main body 2 is formed in a tapered shape which is widened upward, and the upper edge portion 5a of the inner lid 5 is elastically contacted with the tapered inner peripheral surface 2a. It is preferable to cover the reinforcing plate 8 along substantially the entire upper surface of the inner lid 5 so as not to come into contact with the inner lid body 2. In this case, the inner peripheral surface of the inner lid body 5 is closed when the inner lid 5 is closed. The inner lid 5 is fitted smoothly along the 2a without any resistance, and the upper edge portion 5 of the inner lid 5 is
a can be elastically brought into close contact with the inner peripheral surface 2a of the storage main body 2, the opening and closing properties of the inner lid 5 are further improved, and even when the inner lid 5 is reinforced by the reinforcing plate 8, the outer periphery of the reinforcing plate 8 is improved. Since the portion 8a does not come into contact with the storage main body 2, it is possible to ensure the smooth opening and closing of the inner lid 5.

Further, below the upper surface of the floor opening 6, a support frame 11 for supporting the storage case main body 2 has an inner side B of the floor opening 6.

The airtightness between the outer cover 4 and the outer cover 2 can be improved, and the cushioning property of the packing material 75 can prevent squeaking noise when the outer lid 4 or the opening frame 70 is stepped on.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION An example of an embodiment of the present invention will be described below. In this embodiment, an underfloor storage 1 having an outer lid 4 and an integral inner lid 5 is exemplified. The underfloor storage 1 is shown in FIG.
As shown in, the storage body 2 installed in the floor opening 6
And an outer lid 4 with a handle 9 for opening and closing the storage case main body 2, and an inner lid 5 having a heat insulating property arranged between the storage case main body 2 and the outer cover 4. In the figure, 10 is a floor, and 111 is a floor heat insulating material.

Here, the storage case main body 2 is formed in a container shape having a storage opening 3 having a square shape in a plan view at an upper portion thereof, and an inner peripheral surface 2a of the storage case main body 2 is tapered upwardly. The storage case main body 2 is provided with a locking portion 50 (FIG. 5) that is locked from the opening edge of the floor 10 to the pier 11 at the upper end portion of the storage case body 2. The outer lid 4 that opens and closes the storage opening 3 of the storage main body 2 is formed in the same square shape in plan view as the storage opening 3, and the upper surface of the outer lid 4 is arranged substantially flush with the floor 10. The outer peripheral portion of the outer lid 4 is detachably mounted on the upper surface side of the pier 11. A plurality of (two parallel in this embodiment) reinforcing bars 12 are attached to the lower surface 4a of the outer lid 4 to reinforce the outer lid 4 which is often stepped on by a foot.

An inner lid 5 made of a heat insulating material having a square shape in plan view is disposed between the storage case body 2 and the outer lid 4. As the heat insulating material, for example, a foam molded article such as polystyrene foam or urethane foam is used. The inner lid 5 is formed in a trapezoidal shape when viewed from the side, and the lower edge portion 5 of the inner lid 5 is formed.
b is projected outward from the upper edge portion 5a and can be elastically attached to the inner peripheral surface 2a of the storage case body 2. As shown in FIG. 2, a projecting ridge portion 14 having a substantially rectangular frame shape in plan view is provided on the upper surface of the inner lid 5, and between the upper surface of the ridge portion 14 and the lower surface 4 a of the outer lid 4. The planar fastener 16 is interposed in the. The sheet fastener 16 is composed of, for example, a sheet member having a large number of female fasteners protruding therefrom and a sheet member having a large number of female fasteners protruding, and one sheet member is attached to the upper surface of the protruding portion 14. The other planar member is attached to the lower surface 4a of the outer lid 4, and the inner lid 5 can be attached to and detached from the outer lid 4 by engaging and disengaging the male fastening and the female fastening. . Instead of the sheet fastener 16, a double-sided tape may be used, and a tapping screw may be used for screwing. Further, on the upper surface of the inner lid 5, at a position corresponding to the reinforcing bar 12 of the outer lid 4,
An escape recess 13 is recessed below the protrusion 14.

Therefore, when the inner lid 5 is opened and closed, the inner lid 5 made of a foam-molded product formed in a substantially trapezoidal shape when viewed from the side.
The lower edge portion 5b of the bottom is elastically contacted with the inner peripheral surface 2a of the storage main body 2,
Since the upper edge portion 5a is not in contact with the inner peripheral surface 2a of the storage case body 2, the contact area between the inner lid 5 and the storage case body 2 is small, which reduces the frictional force between them. Three
As shown in (a) and (b), the inner lid 5 together with the outer lid 4 can be opened smoothly without resistance. On the other hand, when closing the outer lid 4, the inner lid 5 is pushed down while the lower edge portion 5b of the inner lid 5 is in line contact with the inner peripheral surface 2a of the storage case main body 2, and the inner peripheral surface of the storage case main body 2 is pushed down. Since 2a is formed in a tapered shape that widens upward, the inner lid 5 is fitted smoothly without resistance, and the lower edge portion 5b of the inner lid 5 is elastically attached to the inner peripheral surface 2a of the storage main body 2. Can be closely attached.

By forming the heat-insulating inner lid 5 into a trapezoidal shape when viewed from the side, the frictional force between the inner lid 5 and the storage case body 2 is reduced, and the inner lid 5 is the outer lid. Since it is integrated with 4, the inner lid 5 can be opened and closed only by opening and closing the outer lid 4, and the inner lid 5 can be opened and closed while ensuring airtightness between the inner lid 5 and the storage body 2. It can be smoothly performed on the inner peripheral surface 2a of the storage case main body 2 without resistance, and the airtightness between the inner lid 5 and the storage case main body 2 is ensured to enhance the heat insulating effect, thereby making it possible to cool the cold region. However, it is possible to prevent cold air from being transmitted from the underfloor storage 1 to the room. Further, with the improvement of heat insulation by the inner lid 5, even when the floor 10 is heated or a heating appliance is installed in the kitchen, for example, it is possible to reliably prevent warm air from entering the inside of the storage case body 2 from the inner lid 5. There is also an advantage that the temperature rise in the storage case main body 2 can be suppressed and the effect of keeping the food and drink inside can be kept cool.

Another example of the embodiment of the present invention is shown in FIGS. In this embodiment, the inner lid 5 made of a heat insulating material having a trapezoidal shape when viewed from the side is formed separately from the outer lid 4. That is, the inner peripheral surface 2a of the storage case main body 2 is formed in a tapered shape that widens upward, and the inner lid 5 is formed on the inner peripheral surface 2a.
The inner lid 5 is arranged so that the upper edge portion 5a of the
The outer peripheral portion of the inner lid 5 is detachably supported by a step portion 30 formed on the inner peripheral surface 2a of the storage case body 2. Further, as in the embodiment shown in FIGS. 1 to 3, the upper surface of the inner lid 5 is provided with a ridge portion 14 having a substantially rectangular frame shape in plan view, and the ridge portion 14 is a planar fastener 16.
It differs from the embodiment of FIGS. 1 to 3 in that it is used not as the attachment surface (FIG. 3) but as the knob portion. This ridge 1
The inner lid 5 can be easily opened and closed by pinching 4, and the inner peripheral surface 2a of the storage case main body 2 is formed into a taper shape that expands upward, and the upper edge of the inner lid 5 is larger than the inner peripheral surface 2a. By elastically adhering the portion 5a in line contact with each other, the frictional force between the inner lid 5 and the storage case body 2 is small, the inner lid 5 can be opened and closed without resistance, and the upper edge portion 5a of the inner lid 5 is stored. Cabinet body 2
The inner lid 5 can be fitted more smoothly into the inner peripheral surface 2a which is opened upward, so that the inner lid 5 can be opened and closed more easily.

Therefore, even when the inner lid 5 is formed as a separate type from the outer lid 4, the inner lid 5 can be opened and closed well, and at the same time, the airtightness can be secured and the heat insulating effect can be enhanced. Furthermore, since the ridge portion 14 used in the embodiment of FIG. 1 can be used as it is as a knob portion, one type of inner lid 5 can be used as an integral type with the outer lid 4 or can be used as a separate type. Therefore, there is also an advantage that it can be used properly according to the user's request. Further, the point that the reinforcing bar 12 of the outer lid 4 is released to the escape recess 13 that is recessed downward from the protrusion 14 is the same as in the embodiment of FIGS. In this case, as shown in FIG. 2 (a), the escape recesses 13 are formed in two rows each vertically and horizontally so as to traverse the ridge portion 14, and even when the outer lid 4 is horizontally rotated 90 °. Since the reinforcing bars 12 of the outer lid 4 can be released into either the escape recesses 13 or the lateral escape recesses 13, the reinforcing bars 12 can be rotated even when the outer lid 4 is rotated 90 ° horizontally. The shape of the escape recess 13 is advantageous in that the outer lid 4 can be brought into contact with the upper surface of the inner lid 5 without hindrance, and there is no restriction in the direction of the outer lid 4.

Further, in this embodiment, in order to enhance the heat insulating property of the gap between the outer peripheral surface 2b of the storage case main body 2 and the floor opening 6, the auxiliary heat insulation covering substantially the entire circumference of the outer peripheral surface 2b of the storage case main body 2. Material 7 is provided. The auxiliary heat insulating material 7 is made of a foam molded article such as styrofoam or urethane foam,
The inner peripheral surface of the auxiliary heat insulating material 7 is formed into a tapered surface so as to follow the outer peripheral surface 2b of the storage case body 2 which is formed in a taper shape and spreads upward. This auxiliary heat insulating material 7 is shown in FIG. 5 (bottom view).
As shown in FIG. 3, the auxiliary heat insulating material 7 is formed into a cylindrical shape that covers substantially the entire circumference of the outer peripheral surface 2 b of the storage main body 2.
It is placed between the outer peripheral surface 2b of the storage main body 2 and the floor opening 6 by fixing the storage main body 2 from the outside by placing it on top of 1 and fixing it with an adhesive or a tapping screw, and sandwiching the storage main body 2 from the outside with the auxiliary heat insulating material 7. The airtightness of the storage container body 2 can be secured, and therefore the inner peripheral surface 2 of the storage main body 2
Combined with the heat insulation effect of the inner lid 5 that elastically contacts a, the heat insulation of the entire underfloor storage 1 can be enhanced, and cold air can be more reliably prevented from entering under the floor. In addition, by supporting the auxiliary heat insulating material 7 by using the splint 11 of the floor 10, there is no need for a dedicated part for supporting the auxiliary heat insulating material 7, and there is an advantage that the member can be rationalized. In FIG. 5, reference numeral 2a denotes a tapered inner peripheral surface, 30 denotes a step portion for receiving the inner lid 4, and 50 denotes an opening edge of the floor 10 from the opening edge of the pier 11.
It is a locking portion that is locked over.

Further, in addition to the structure in which the inner lid 5 is formed separately from the outer lid 4 as shown in FIG. 5, the upper surface of the inner lid 5 is formed so as not to come into contact with the storage case body 2 as shown in FIG. The reinforcing plate 8 may be provided along the entire surface. Other configurations are similar to those of the embodiment of FIG. In this embodiment, the reinforcing plate 8
Is formed of, for example, a resin material having a thickness of 1.5 mm, and the ridge portion 1
By covering the reinforcing plate 8 in a shape along the upper surface of the inner lid 5 so that the clearance 4 and the escape recess 13 appear on the upper surface of the inner lid 5, the strength of the inner lid 5 can be increased and deformation or the like can be prevented. Like Moreover, since the outer peripheral portion 8a of the reinforcing plate 8 is disposed with a constant gap G (for example, about 2.0 mm) from the inner peripheral surface 2a of the storage main body 2 as shown in FIG. 6B,
When the inner lid 5 is taken in and out, there is no concern that the outer peripheral portion 8a of the reinforcing plate 8 will come into contact with the storage case body 2, and the strength of the inner lid 5 can be increased while at the same time ensuring smooth opening and closing of the inner lid 5. .

7 to 10 show still another embodiment of the present invention. In this embodiment, below the upper surface of the floor opening 6, a support frame 11 made of a shackle for supporting the storage case main body 2 is provided so as to project inward B over substantially the entire circumference of the floor opening 6. An opening frame 70 having a substantially L-shaped cross section is fitted over the support frame 11 over substantially the entire circumference of the inner peripheral surface 6a of the floor opening 6. The opening frame 70 is made of, for example, a metal material such as aluminum, and extends vertically along a flange-shaped locking piece 71 that is locked to the upper surface of the floor opening 6 and the inner peripheral surface 6 a of the floor opening 6. The vertical piece 72, and the horizontal piece 7 provided so as to project inward B from the lower end side of the vertical piece 72.
3 are integrally formed with each other, a screw hole is provided in a part of the horizontal piece 73, and a screw 77 is fixed to the support frame 11 via the horizontal piece 73.

The lower end of the vertical piece 72 is placed on the upper surface 11a of the support frame 11 near the outer end thereof with a packing material 76 interposed therebetween. The packing material 76 is made of, for example, a rubber-like elastic body such as EPDM, and the lower end surface of the vertical piece 72 is closed with the gap between the outer surface of the lower portion of the vertical piece 72 and the inner peripheral surface 6a of the floor opening 6 being closed. It covers the entire surface. This packing material 76
Is the support frame 11 and the vertical piece 7 over substantially the entire circumference of the support frame 11.
The airtight seal is provided between the two.

At the tip of the horizontal piece 73, the storage main body 2
An insert piece 74 that is inserted between the support frame 11 and the flange portion 2c protruding outward from the upper edge of the is integrally provided. Between the lower surface of the insertion piece 74 and the upper surface 11b near the inner end of the support frame 11, and between the upper surface of the insertion piece 74 and the flange portion 2c.
A flat plate-like packing material 75 made of a rubber-like elastic body such as EPDM is interposed between the lower surface and the lower surface. The packing material 75 hermetically seals between the support frame 11 and the insertion piece 74 and between the flange portion 2c and the insertion piece 74 over substantially the entire circumference of the support frame 11.
In FIGS. 8 and 9, 80 is a mortar provided between the storage main body 2 and the floor slab 81, and 82 is a vinyl sheet. Other configurations are similar to those of the embodiment of FIG.

The packing material 75 provided on the upper and lower surfaces of the insertion piece 75 is used for the flange portion 2c of the storage main body 2.
The airtightness between the support frame 11 and the opening frame 70 and the airtightness between the opening frame 70 and the support frame 11 are respectively secured. Further vertical piece 7
The packing material 76 provided at the lower end of 2 further secures the airtightness between the support frame 11 and the opening frame 70. Therefore,
The floor opening 6 and the storage main body 2 are provided over substantially the entire circumference of the floor opening 6.
It is possible to improve the airtightness between the floor opening 6 and the floor, and it is possible to prevent the cold air from being transmitted from the floor opening 6 to the room especially in the winter. Furthermore, since the packing material 75 is formed of a rubber-like elastic body such as EPDM, the packing materials 75 and 76 have excellent thermal stability and aging resistance, and for example, the opening frame 70 has a heat transfer property such as aluminum. Even when it is made of a metal material having a high heat resistance, the heat transmitted through the opening frame 70 can be blocked by the packing materials 75 and 76. As a result, for example, even when the floor 10 is heated or a heating appliance is installed in the kitchen, the storage main body 2 is transmitted along the opening frame 70.
Since the heat can be prevented from being transmitted to the inside, the temperature rise in the storage case main body 2 can be suppressed, and the effect of keeping the food and drink inside can be kept cool.

Furthermore, the cushioning properties of the packing materials 75 and 76 can absorb the shock applied to the opening frame 70 from above, and when the outer lid 4 is stepped on or the outer lid frame 4b or the opening frame 70 is stepped on, a squeaking noise is produced. There is also an advantage that it can be prevented. The packing material 75 may be made of a material other than EPDM, in short, as long as it is a material having both airtightness and cushioning property.

In each of the above-described embodiments, the storage case main body 2

The heat insulation of the entire underfloor storage can be improved, and the cold air from under the floor can be more reliably prevented from entering the room.

According to a fourth aspect of the present invention, the inner peripheral surface of the main body of the storage container according to the first aspect is formed in a taper shape that is widened upward, and the tapered inner peripheral surface has an upper edge portion of the inner lid. In addition to the effect of claim 1, in addition to the effect of claim 1, in addition to elastically contacting, the reinforcing plate is covered along the substantially entire upper surface of the inner lid so that the inner lid is closed. The inner lid can be fitted smoothly along the inner peripheral surface of the main body without resistance, and the upper edge portion of the inner lid can be elastically adhered to the inner peripheral surface of the storage main body, and the opening and closing property of the inner lid is further improved. Further, since the outer peripheral portion of the reinforcing plate does not come into contact with the storage main body, there is no concern that the outer peripheral portion of the reinforcing plate comes into contact with the storage main body when the inner lid is taken in and out,
Although the inner lid is reinforced by the reinforcing plate, the inner lid can be smoothly opened and closed.

According to a fifth aspect of the present invention, a support frame for supporting the storage case main body is provided below the upper surface of the floor opening portion of the first aspect so as to project inward of the floor opening portion.
