Abstract
Abstract In a warming panel of a construction, wherein liquid for a heat insulating layer (3) is injected into an interior space of an outer shell structure (8) of a hollow planar construction, there is provided a buffer plate (13) or a flow guide plate (20) in the interior of the abovementioned outer shell structure (8), where the abovementioned liquid to be injected is impinged, to thereby restrict the flowing direction of the liquid as injected so as to make it possible to prevent the high pressure injected liquid from impinging on those fixed parts (6) provided in the outer shell structure (8) or those connected portions (1B) of the outer shell structure, thus avoiding unnecessary shifting of the fixed parts (6), or deformation or damage of the connected portions of the outer shell structure (8).

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
296 words
Intermediate structure for use in forming an insulated warming panel, said intermediate structure comprising: (a) an outer shell structure of a hollow planar construction, said outer shell structure comprising a front surface plate, a rear surface plate, and a plurality of side walls extending between said front surface plate and said rear surface plate; (b) a conduit tube for passing heat medium therethrough disposed in the interior of said outer shell structure; (c) a charging port for heat insulating material which is liquid when charged, said charging port extending from the exterior to a volume in the interior of said outer shell structure in which the heat insulating material is initially received, said charging port extending through a first one of said plurality of side walls and defining the initial flow path of the heat insulating material into the interior of said outer shell structure; and (d) a flow guide plate disposed in the interior of said outer shell structure in the initial flow path of the heat insulating material into the interior of said outer shell structure, said flow guide plate: (i) defining one boundary of said volume; (ii) projecting from a second one of said plurality of side walls and extending toward a third one of said plurality of said walls opposite to said second one of said plurality of side walls by a distance that is small relative to the distance between said second and third side walls; and (iii) being sized, shaped, and positioned so that, when a liquid heat insulating material is charged into the interior of said outer shell structure through said charging port, it impinges upon said flow guide plate and is redirected thereby before it strikes the inner surface of said outer shell structure opposite said charging port.
Claim 2
Dependent Claim
296 words
Intermediate structure for use in forming an insulated warming panel, said intermediate structure comprising: (a) an outer shell structure of a hollow planar construction, said outer shell structure comprising a front surface plate, a rear surface plate, and a plurality of side walls extending between said front surface plate and said rear surface plate; (b) a conduit tube for passing heat medium therethrough disposed in the interior of said outer shell structure; (c) a charging port for heat insulating material which is liquid when charged, said charging port extending from the exterior to a volume in the interior of said outer shell structure in which the heat insulating material is initially received, said charging port extending through a first one of said plurality of side walls and defining the initial flow path of the heat insulating material into the interior of said outer shell structure; and (d) a flow guide plate disposed in the interior of said outer shell structure in the initial flow path of the heat insulating material into the interior of said outer shell structure, said flow guide plate: (i) defining one boundary of said volume; (ii) projecting from a second one of said plurality of side walls and extending toward a third one of said plurality of said walls opposite to said second one of said plurality of side walls by a distance that is small relative to the distance between said second and third side walls; and (iii) being sized, shaped, and positioned so that, when a liquid heat insulating material is charged into the interior of said outer shell structure through said charging port, it impinges upon said flow guide plate and is redirected thereby before it strikes the inner surface of said outer shell structure opposite said charging port.
Claim 3
Dependent Claim
33 words
Intermediate structure as recited in claim 1 wherein said flow guide plate is mounted on an inner wall of the interior of said outer shell structure and projects inwardly from said inner wall.
Claim 4
Dependent Claim
40 words
Intermediate structure as recited in claim 1 wherein: (a) the interior of said outer wall structure is polygonal in plan view and (b) said flow guide plate projects inwardly from one wall of the interior of said outer shell structure.
Claim 5
Dependent Claim
60 words
Intermediate structure as recited in claim 1 wherein said front and rear surface plates and said plurality of side walls of said outer shell structure forms: (a) a first component in the shape of an open-faced parallelepipedal box and (b) a second component in the shape of a planar cover which closes the open face of said open-faced parallelepipedal box.
Claim 6
Dependent Claim
54 words
Intermediate structure as recited in claim 1 and further comprising a resilient buffer piece disposed in the interior of said outer shell structure, said resilient buffer piece making surface contact with the side of said flow guide plate opposite to the side against which the liquid heat insulating material impinges and providing support thereto.
Claim 7
Dependent Claim
34 words
Intermediate structure as recited in claim 5 wherein said resilient buffer piece extends between said flow guide plate and an inner wall of said outer shell structure which is opposite to said charging port.
Claim 8
Dependent Claim
16 words
Intermediate structure as recited in claim 1, wherein said plurality of side walls define a rectangle.
Claim 9
Dependent Claim
61 words
Intermediate structure as recited in claim 1, wherein: (a) said charging port is located in close proximity to said second one of said plurality of side walls and (b) the initial flow path of the heat insulating material into the interior of said outer shell structure is at least approximately parallel to said second one of said plurality of side walls.
