PIPE RACK Filed Oct. 21, 1965 v INVENTOR. ROBERT l4. PFE/FFER A TTORNEV United States Patent 3,382,986 PIPE RACK Robert W. Pfeiffer, Bronxville, N .Y., assignor of one-half to Wayne C. Jaeschke, Dobhs Ferry, N.Y. Filed Oct. 21, 1965, Ser. No. 499,590 4 Claims. (Cl. 21160) ABSTRACT OF THE DISCLOSURE A collapsible pocket-sized pipe rack comprising in combination: a relatively thin sheet forming a table, an elongated aperture cut in the table, the edges of said aperture providing support ledges for a smokers pipe, leg means in hinged connection with said table for supporting said table while in use, said leg means being foldable and shaped so as to closely embrace said table to form a compact configuration suitable for pocket insertion. Elongated blanks having relatively smaller elongated apertures cut therein, which are insertable within the elongated aperture to provide means for adapting the .pipe rack to support relatively smaller pipes.
The present invention relates to novel means for supporting one or more smokers pipes, and more specifically, in one aspect, relates to a novel collapsible pipe rack, and in another aspect to a novel rigid pipe rack.
It is the principal object of the present invention to provide a novel pipe rack which is capable of retaining one or more pipes having a wide range of bowl sizes in a stable position with the axis of the bowl disposed in a vertical plane and the stern tilted at a proper angle for drainage.
Another object is to provide a relatively small, collapsible pipe rack which is capable of being rapidly compacted into a configuration suitable for being inserted into the breast pocket, for example, of a mans suit or shirt for carriage to the point of use.
Another object is to provide a novel and versatile, rigid pipe rack which is decorative and attractive as well as functional.
Further objects and advantages inherent in the present invention will become apparent from the following detailed description of the invention with reference to the drawings.
FIGURE 1 is a perspective view of one preferred embodiment of the pocket-sized pipe rack of the present invention shown in its opened position and illustrating actual support of a pipe by the edges of a pair of elliptical shaped apertures cut through table 10.
FIGURE 2 is a plan view of the rack of FIGURE 1 shown in the closed position with support legs 35 folded under table 10, and showing the elliptical apertures defined by edges 15 and 25.
FIGURE 3 is a side elevation view of the folded rack shown in FIGURE 2 which illustrates the curvature of table and matching curvature of legs 35 preferred for reasons of comfort and appearance when carrying the folded rack in the breast pocket.
FIGURE 4 is a perspective view of a rigid pipe rack which illustrates support of two pipes by the edges of elliptical apertures 115 and 120 cut through an arched, self-supporting table 110.
Referring now to FIGURE 1, table 10 is supported by foldable support legs 35, which are joined to table 10 by suitable hinging means 8 shown in FIGURE 2. An elongated aperture in table 10 is defined by edges and 25. Bowl 40 is supported by contact with edge 15 at one point on each side of the bowl and stem 45 is supported by contact with edge 25. In this embodiment, table 10 comprises a portion of a right circular cylinder having a radius of 8 inches, length along the longitudinal axis of 4 /2 inches,
and arc length of 2% inches as defined by a subtended angle of 19.7 degrees. The use of a curved surface conforms to the curvature of the male body in the region of the breast pocket, and also provides beam strength permitting thinner and lighter construction fo the rack. A rack having table dimensions of about 2% by 4 /2 inches is readily insertable in the breast pocket of most shirts and jackets. While table 10 is preferably formed in the shape of a cylindrical arch any suitable curvature as well as a fiat surface can be utilized. Foldable legs 35 are formed having a curvature corresponding to the curvature of table 10 in order to closely embrace the table and thereby provide maximum compactness in the closed position. Each leg 35 preferably has an arc length of slightly less than about one-half that of table 10. In this embodiment, hinges 8 are restricted such that legs 35 preferably form about a -degree angle with table 10 in the open position.
FIGURE 2 illustrates the preferred shape of apertures defined by edges 15 and 25 which is elliptical. The elliptical shape is preferable since an ellipse is the curve formed when a right circular cylinder is cut byv a plane not perpendicular to the base; and inspection of FIGURE 1 reveals that when a circular pipe bowl is extended downwardly in a vertical plane with its longitudinal axis held at an angle to the vertical such that surface 10 is intersected, a curve of approximately elliptical shape is formed by the locus of intersecting points. It has been discovered that when the apertures are made at least approximately elliptical a wide size range of pipe bowls are accommodated Within a single aperture. The support provided is a three-point support, where one point on each side of the bowl is maintained in contact with the edges of the aperture, and the stem forms the third support point. It has likewise been found that a circular opening is not desirable for use in the present invention since the support provided thereby is an unstable two-point support. In general, any elongated aperture which provides three-point support is useful in connection with the present invention.
An ellipse is defined as the locus of a point such that the sum of its distances from two fixed points is constant. The two fixed points are called the foci and the distance between them along the major axis is 2c. The equation of an ellipse is (x /a )+(y /b )=1, where: 2a=overall length of ellipse on the major, x-axis; 2b =overall width of ellipse on the minor, y-axis; and c'-=a b where '-c are the foci on the x-axis. The chord through either focus per pendicular to the major axis is called the latus rectum located at x=:c; at the latus rectum y=:L-b a. Hence the length of the latus rectum is 2b /a.
For use with table 10 as previously defined in the specific embodiment for the collapsible rack, the optimum elliptical apertures are obtained by setting 2b=2s.
While the collapsible pipe rack is intended to hold only one pipe at any given time, it is advantageous that it be adaptable to hold pipe bowls of many different sizes. It has been determined that the bowl is adequately supported even if the width of the elliptical opening is only about -inch smaller than the maximum diameter of the bowl. Examination of conventional bowls reveals that when viewed longitudinally along the stem, such bowls taper to a smaller width at the bottom and that one ellipse of given width is therefore capable of accommodating pipe bowls over a wide range of sizes with adequate stability.
In order to provide further variation in the sizes of the pipe bowls which can be accommodated table 10 should contain as many elliptical openings as possible. However, the overall dimensions of the collapsible rack limit the permissible number of openings to two intersecting base ellipses. FIGURE 2 shows a first base ellipse 15 where 2b=l inches, which accommodates most conventional pipe bowls. In order to reduce overall length, ellipse 15 is truncated at its latus rectum 16. In general, the intersecting ellipses are truncated at a chord in each ellipse which is located between the latus rectum and the end of the ellipse.
The second base ellipse 20, where 2b=1 inches, is provided in table to accommodate pipe bowls of very large diameters. In ellipse 20 the width of the truncating chord matches the width of the latus rectum 16. It has been found that the two base ellipses, in general, accommodate pipe bowls ranging in maximum width from about 1 5. to about 1 inches.
To provide still further flexibility, an approximately elliptical blank 30, which is truncated at one end thereof, and which has a smaller elliptical aperture 25 cut therein, is removably inserted within the edges of aperture 20 in table 10. Elliptical aperture 25 is inches wide. For maximum attractiveness, the open end of ellipse 25 is extended past its latus rectum to intersect with the hypothetical projection of ellipse past its latus rectum. The outer edge of insert 30 is designed to be contiguous with the edges of aperture such that the insert is held in place by frictional forces alone. If desired, the outside edge of that portion of insert 30 which is adjacent to its open end can be made slightly larger than aperture 20 to increase the frictional forces which hold insert 30 in place in aperture 20.
FIGURE 4 illustrates a rigid pipe rack in which table 110 comprises an arch formed by a portion of a right circular cylinder having a radius of about four-inches, an arc length of about 7.15 inches as defined by a subtended arc 103.2 degrees, and longitudinal axis of about 4 /2 inches. In general table 110 can be formed from a suitable portion of any surface of revolution such as, e.g., a cylinder, ellipse, parabola, hyperbola, or sphere. In FIG- URE 4 elongated apertures 115 and 120 are provided, such apertures being preferably full ellipses defined by 2a=4b. Inserts such as insert 30 shown in FIGURE 2 can be employed to adapt apertures 115 and 120 to hold pipe bowls of varying sizes. In the embodiment shown in FIGURE 4 the apertures are preferably disposed to include the line of elevation in aperture 110.
Having thus described the present invention with reference to specific embodiments thereof, many modifications and alterations thereof will become apparent to those skilled in the art without departing from the scope of the present invention which is limited only by the claims.
