Abstract

A frame structure including an elongated bar having clamping legs adapted to clamp between them an elongated member perpendicular to the bar. A second bar is positioned in generally perpendicular relation to both the first mentioned bar and the member, and means are included for forcing the bars together in such a way that they are firmly positioned relative to each other with no movement therebetween when either bar is under load.

Claims

1. A frame structure adapted to be clamped to an elongated member comprising:

a. a first elongated bar;

b. a pair of spaced generally straight legs extending first laterally outwardly then generally downwardly from and substantially perpendicular to said bar substantially equidistant therefrom adapted to be disposed on one side of said elongated member and abut against said member;

c. a third generally straight leg associated with said bar adapted to be disposed on the other side of said elongated member and abut there against, said third leg extending generally downwardly from and substantially perpendicular to said bar and in substantially the same plane as said bar, said third leg including elongated member gripping means associated therewith for selectively drawing said third leg toward said first and secOnd legs to grip the elongated member between said spaced legs and said third leg and to separate said legs to release said elongated member from between said spaced legs and said third leg;

d. a second elongated bar positioned to contact the first elongated bar; and

e. forcing means operatively engaging said first an second elongated bars for selectively forcing the first and second elongated bars together and releasing them from contact with each other.

2. A frame structure according to claim 1 wherein the forcing means for selectively forcing the first and second elongated bars together comprise:

a. a generally U-shaped member defining a bottom portion and a pair of generally parallel sides which define apertures through which the first elongated bar is disposed, the second elongated bar being disposed between the sides of the generally U-shaped member and between the bottom portion thereof and the first elongated bar; and

b. bolt means threaded through the generally U-shaped member at an angle between 0* and 90* from the longitudinal axis of the first elongated bar to bear on the second elongated bar and force the second elongated bar against the first elongated bar and one side of the generally U-shaped member.

3. A frame structure according to claim 2 wherein the first elongated bar is square in cross section, the second elongated bar is equilaterally octagonal in cross section, and the bolt means is threaded through the generally U-shaped member at an angle of approximately 45* from the longitudinal axis of the first elongated bar.

4. A frame structure according to claim 1 wherein the second elongated bar is equilaterally octagonal in cross section, and wherein the forcing means for selectively forcing the first and second bars together comprise:

a. a block having a first aperture through which the first elongated bar is disposed, and a second aperture of generally equilaterally octagonal cross section through which the second elongated bar is disposed; and

b. bolt means threaded through the block to bear on the first elongated bar and force it against the second elongated bar, the inner surface of the second aperture opposite the contacting surfaces of the first and second bars being recessed so that the second bar bears only against the surfaces of the second aperture adjoining the recessed surface.

5. A frame structure according to claim 1 wherein the first elongated bar is hollow, and wherein said elongated member gripping means includes a sliding member within the first elongated bar and to which the third leg is fixed, the third leg being movable toward and away from a point between the spaced legs by sliding the sliding member back and forth within the first elongated bar, and a threaded member threadably engaged with the sliding member and having one end extending from the other end of the elongated bar, the other end of the threaded member being disposed in a hollow portion within the sliding member and being limited from passing through the threaded portion of the sliding member.

6. A frame structure adapted to be clamped to an elongated member comprising:

a. a first elongated bar of cross section;

b. first, second and third generally straight legs extending from one end of the first elongated bar, the first and second legs extending first laterally outwardly then generally downwardly from and substantially perpendicular to said bar substantially equidistant therefrom adapted to be disposed on one side of the elongated member, the third leg extending generally downwardly from and substantially perpendicular to said bar and in substantially the same plane as said bar, said third leg being movable toward and away from a point between the first and second legs and adapted to abut against the other side of said elongated member;

c. elongated member gripping means associated with the first elongated bar for selectively moving the third leg toward the point betweEn the first and second legs to grip the elongated member therebetween and moving the third leg away from the point between the first and second legs to release the elongated member from between said legs;

d. a second elongated bar of equilaterally octagonal cross section disposed perpendicular to the first elongated bar and having one surface thereof in contact with one surface of the first elongated bar;

e. a generally U-shaped member defining a bottom portion and a generally parallel pair of sides which define square apertures through which the first elongated bar is disposed in perpendicular relation to the sides, the second elongated bar being disposed between the sides of the generally U-shaped member and between the bottom portion thereof and the first elongated bar; and

f. bolt means threaded through the generally U-shaped member perpendicular to the longitudinal axis of the second elongated bar and at an angle of 45* from the longitudinal axis of the first elongated bar to bear on the second elongated bar and force the second elongated bar against the first elongated bar and one side of the generally U-shaped member.

7. A frame structure adapted to clamp to an elongated member comprising:

a. a first hollow elongated bar;

b. first, second and third legs extending from one end of the first elongated bar, the first and second legs being fixed relative to the bar and disposed to one side of the elongated member, the third leg being movable toward and away from a point between the first and second legs and disposed on the other side of the elongated member;

c. means associated with the first elongated bar for moving the third leg toward the point between the first and second legs to grip the elongated member and moving the third leg away from the point between the first and second legs to no longer grip the elongated member, said means including a sliding member within the first elongated bar and to which the third leg is fixed, the third leg being movable toward and away from the point between the first and second legs by sliding the sliding member back and forth within the first elongated bar, and a threaded member threadably engaged with the sliding member and having one end extending from the other end of the elongated bar, the other end of the threaded member being disposed in a hollow portion within the sliding member and being limited from passing through the threaded portion of the sliding member;

d. a second elongated bar equilaterally octagonal in cross section positioned to contact the first elongated bar; and

e. means for selectively forcing the first and second elongated bars together comprising, a block having a first aperture through which the first elongated bar is disposed, and a second aperture of generally equilaterally octagonal cross section through which the second elongated bar is disposed and bolt means threaded through the block to bear on the first elongated bar and force it against the second elongated bar, the inner surface of the second aperture opposite the contacting surfaces of the first and second bars being recessed so that the second bar bears only against the surfaces of the second aperture adjoining the recessed surface.
