United States Patent 3,194,527 BRACKET Jack Gross, 2710 Emmet Road, Silver Spring, Md. Filed Apr. 1, 1963, Ser. No. 269,244 3 Claims. (Cl. 248-435) The present invention relates to brackets which can be used as a support such as a shelf-bracket or can be used as a brace between framing members and the like.

The primary object of the present invention is to provide a bracket of improved strength by using the anticlastic surface of the hyperbolic parabolcid in distributing the forces applied to the bracket.

Further objects of the present invention are to provide a light weight bracket formed of a single sheet of material, inexpensive to manufacture, and having a high degree of strength.

Further objects and advantages of the present invention will be readily apparent from the following detailed description taken in conjunction with the accompanying drawing wherein:

FIGURE 1 is an isometric view of the bracket forming the subject matter of the present invention.

FIGURE 2 is a side view of the bracket of FIGURE 1 illustrating the use of the bracket as a shelf support.

FIGURE 3 is an isometric view of the bracket of FIG- URE 1 illustrating the use of the bracket as a reinforcing brace, and

FIGURE 4 is a side view of a modified form of bracket used as an external brace.

FIGURE 5 is a horizontal sectional view of the bracket in the position shown in FIGURE 3.

FIGURE 6 is a vertical sectional view of the bracket in the position shown in FIGURE 3.

Referring to the drawing in detail and particularly to FIGURES l, 2 and 3, the bracket forming the subject matter of the present invention is generally indicated by numeral 10. The bracket may be made of metal or equivalent material and is shaped to the form disclosed from a single sheet of material. The body portion of the bracket, indicated by numeral 11, comprises the surface of a hyperbolic paraboloid, said surface terminating at its edge in a flattened surface 12 for attachment to a support. The flattened surface 12 is provided with a plurality of openings 13 for receiving screws or the like for anchoring the bracket to a support.

FIGURE 2 illustrates the use of the bracket as a shelfsupporting bracket between a vertical Wall 15 and a shelf member 16. In this form of use, the bracket may be considered as being in vertical position. The same bracket when turned on its side or in horizontal position serves I as a brace between

framing members

17 and 18.

As seen in FIGURE 1, the flattened surface 12 which extends completely around the body portion 11, comice prises a pair of substantially V-shaped sections with the numeral 19 indicating the apex of the V, said sections being joined to each other at right angles to each other with the apex of the angle being indicated by numeral 29. Thus, as viewed in FIGURE 2, with the bracket in vertical position, a vertical section taken through points 19 will define a hyperbolic curve and a transverse section taken through points 26 will define a parabolic curve. In FIGURE 3 the bracket is identical with the bracket shown in FIGURE 2 except that it is turned and used in a horizontal position as a bracing member.

FIGURE 4 discloses a slightly modified form of bracket wherein the body portion 11' terminates in a flattened surface 12' defining

sections

21 and 22 which instead of being at right angles to each other, define an angle of Thus, a pair of brackets as shown in this figure, can be used as an external brace between

members

23 and 24. The two brackets are secured to each other by means of bolts 25 and to

members

23 and 24 by screws 14. It will be understood that the angle between

sections

21 and 22 may vary depending upon the angle between members: 23 and 24.

it will thus be apparent that the present invention is well adapted to accomplish the objects and advantages set forth. It will be understood that minor changes may be made in the details of construction without departing from the spirit and scope of the invention except as may be required by the appended claims.

What is claimed as new is: V 1. A bracket comprising a hollow curved body portion terminating in a flattened portion defining a pair of substantially V-shaped sections, each of said sections being angularly disposed with respect to the other of said sections for securement to a surface, said bracket when used in a vertical position being so shaped that a vertical section through the body portion thereof defines a hyperbolic curve and a horizontal section through the body portion defines a parabolic curve, said body portion having an outer surface in the form of a hyperbolic paraboloid.

2. A bracket as defined in claim 1, said flattened portion comprising two sections at right angles to each other.

3. A bracket as defined in claim I, said flattened portion comprising two sections at an angle of 135 to each other.

Claims

1. A BRACKET COMPRISING A HOLLOW CURVED BODY PORTION TERMINATING IN A FLATTENED PORTION DEFINING A PAIR OF SUBSTANTIALLY V-SHAPED SECTIONS, EACH OF SAID SECTIONS BEING ANGULARLY DISPOSED WITH RESPECT TO THE OTHER OF SAID SECTIONS FOR SECUREMENT TO A SURFACE, SAID BRACKET WHEN USED IN A VERTICAL POSITION BEING SO SHAPED THAT A VERTICAL SECTION THROUGH THE BODY PORTION THEREOF DEFINES A HYPERBOLIC CURVE AND A HORIZONTAL SECTION THROUGH THE BODY
