Abstract
Abstract A solar heating device comprising an upright tubular post, a rigid support member protruding perpendicularly from the post, and a generally paraboloidal reflector having a rigid arm extending along the axis of the reflector from the center thereof towards the focal point. A pivot perpendicular to a free end of said arm is selectively pivotally mounted and secured in one of a plurality of notches in said support member to provide a compensation for the lateral displacement of the focal point as the reflector is tilted. A height adjustable grid mounted on a tube slidably received within the post enables the support of an object to be heated. A rod indicating the focal point of the reflector can be disposed along the axis thereof.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
133 words
A solar heating device comprising a post, a rigid support member extending transversally of the post, a concave generally paraboloidal reflector including a rigid arm extending aLong the axis of the reflector from the center thereof towards the focal point thereof, means for pivotally mounting said arm to said support member about a pivoting axis perpendicular to the axes of said post and said reflector whereby said reflector can be oriented relative to said post, said pivoting axis being spaced apart from the center of said reflector towards the focal point of said reflector, said post carrying towards an upper end thereof means for supporting an object to be heated, and means for adjusting the relative position of said object supporting means and said support member along the axial direction of said post.
Claim 2
Dependent Claim
133 words
A solar heating device comprising a post, a rigid support member extending transversally of the post, a concave generally paraboloidal reflector including a rigid arm extending aLong the axis of the reflector from the center thereof towards the focal point thereof, means for pivotally mounting said arm to said support member about a pivoting axis perpendicular to the axes of said post and said reflector whereby said reflector can be oriented relative to said post, said pivoting axis being spaced apart from the center of said reflector towards the focal point of said reflector, said post carrying towards an upper end thereof means for supporting an object to be heated, and means for adjusting the relative position of said object supporting means and said support member along the axial direction of said post.
Claim 3
Dependent Claim
36 words
A device according to claim 1, comprising a rod fixed at least approximately along the axis of the reflector, said rod including a free end disposed in the vicinity of the focal point of the reflector.
Claim 4
Dependent Claim
46 words
A device according to claim 2, in which said arm includes means defining a groove disposed along the axial direction of said reflector for receiving and guiding said rod, said rod being removably held in said groove means of said arm by means of a screw.
Claim 5
Dependent Claim
100 words
A device according to claim 2, in which said object supporting means is formed by a grid and means for securing said grid in a plane perpendicular to the axis of said post, said grid including means defining therein an elongate central opening extending generally perpendicularly to the axis of said post, and comprising means for relatively angularly disposing said grid and said support member about said post to place said opening means of said grid along the trajectory of said free end of said rod when the orientation of said reflector is modified by pivoting about said pivoting axis.
Claim 6
Dependent Claim
31 words
A device according to claim 1, comprising means for adjusting the position of said pivoting axis relative to said support member along a direction perpendicular to the axis of said post.
Claim 7
Dependent Claim
92 words
A device according to claim 4, in which said support member is formed by a fixed second arm protruding perpendicularly from said post, said second arm including means defining in an upper face thereof a plurality of discrete notches disposed spaced apart along said second arm, the pivotally mounted first arm of said reflector carrying a pivot protruding perpendicularly therefrom, and means for securing said first arm relative to said second arm with said pivot selectively disposed in one of said notch means and with said first arm at a selected inclination.
Claim 8
Dependent Claim
88 words
A device according to claim 6, in which said post is tubular and said object supporting means includes a grid pivotally mounted on a tube which is slidably mounted within said post, and means for holding said grid in a plane perpendicular to the axis of said post, said device further comprising means for fixing said tube relative to said post with said grid at a selected distance from said second arm and extending from said post in a direction opposite to the direction of said second arm.
Claim 9
Dependent Claim
86 words
A device according to claim 1, in which said reflector is made up of a plurality of segments pivotally jointed at corresponding one ends thereof about a shaft secured on said arm, said segments being foldable and unfoldable between a storage position in which the segments are superposed and an expanded position in which two extreme segments meet together whereby said segments form a generally paraboloidal reflector, adjacent edges of said extreme segments including means defining an aperture in said reflector for passage of said post.
Claim 10
Dependent Claim
43 words
A device according to claim 8, in which parts of said extreme segments which meet together in said expanded position include means for securing together said parts of said segments in selected positions to enable adjustment of the focal point of said reflector.
