DESCRIPTION OF THE PRIOR ART In such structures as is shown in the following patents: Hartman, No. 2,566,886 issued Sept. 4, 1951, Flora, No. 2,697,862 issued Dec. 28, 1954, Bender et al., No. 2,732,761 issued Jan. 31, 1956, Havener, No. 3,154,276 issued Oct. 27, 1964, Wallshein, No. 3,052,004 issued Sept. 4,1962, and Schneider et al. No. 3,295,812 issued J an. 3, 1967, when pressure is applied by and of the section toward another, binding relationship between the sections and the rod is rendered ineffective. For example, if leg or section 1 of Schneider et al. is pressed toward leg or section 2, the rod 13 is released. Therefore, leg 1 cannot support a load.
In one embodiment of applicants invention when pressure is applied, one one end section of the retainer, toward another section, binding relationship is enhanced between the retainer and the rod, and, in another embodiment, when pressure is'applied to either end section toward another section, binding relationship is enhanced between the retainer and rod.
. SUMMARY OF THE INVENTION The integral retainer of the present invention is formed from elongated strip of flexible and inherently resilient material and includes two end sections and at least one intermediate section, two of the sections being provided with alignable holes for receiving the rod; These cooperatetwith one another to provide binding 'relationship between the rod and the walls forming the holes. The rod is freely movable relative to 'the retainer when the binding relationship, created by the said two sections is rendered ineffective.
Other features and the advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawings, wherein preferred embodiments of the invention are allustrated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring first to the embodiment shown in FIGS. 1 to 4, the integral retainer is shown at 20 and a rod is shown at 22. The retainer is formed of a strip of flexible and inherently resilient material such as spring metal or flexible and resilient plastic. It is folded to include two end sections 24 and 26 and two intermediate sections 28 and 30. The end of section 24 extends longitudinally beyond sections 26 and 28. While not necessary, but for illustrative purpose, the end section 24 is disposed at right angles with intermediate section 30. The intermediate section 28 is bent back toward end section 24 at an obtuse angle and end section 26 is bent toward end section 24 at an acute angle with section 28. The outer end of end section 26 is spaced from the confronting side of end section 24. j
Sections 24, 26 and 28 are provided with axially alignable holes 32, 34 and 36, respectively, for receiving rod 22, as shown in FIGS. 3 and 4. The diameter of the holes 34 and 36 are slightly larger than the diameter of the rod 22, and the hole 32 may be slightly larger in diameter than the holes 34 and 36.
By applying bending pressure on end section 26 toward intermediate section 28, the holes 34 in section 26 are axially aligned with holes 32 and 36 in end section 24 and intermediate section :28 and can receive the rod 22. Upon releasing the bending pressure, due to the resiliency of the retainer, binding and holding relationship is established between the rod and the walls forming the openings 34 in end section 26 andlintermediate section 28.
If pressure is applied on end section 24 toward intermediate section 28,-= the angular relationship between section 28 and the rod is increased, thus enhancing the binding relationship between the retainer and the rod. Thus, the end section 24can function as a stop or as a support. The retainer is shown as a support in FIG. 4; it supports an object such as a shelf section 38. Obviously the retainer can be used for many other purposes, for example, as a stop on a rod or pin.
The binding relationship can be rendered ineffective readily by merely moving section 26 toward section 28 to axially align holes 34 and 36. Bars 40 are providedon section 26 for the ready manipulation of that section. As shown in FIG 3, a forefinger pushing on an ear with a thumb steadying the corner 42, between sections 26 and 28, releases the binding relationship.
Referring now to the embodiment shown in FIGS. 5, 6 and 7, the integral retainer 50 includes an end section 54, end section 56 and only one intermediate section 58. End section 54 and intermediate section 58 are disposed at an obtuse angle with one another, and end section 56 and intermediate section 58 are at an a ctue angle. The end and intermediate sections 56 and 58 are provided, respectively, with holes 64 and 66, for receiving the rod 22, or as shown in FIG. 7, for receiving a coupling pin 52. The diameter of the holes is slightly larger than the diameter of the rod or pin received thereby.
The retainer 50 can receive the rod by pushing end section 56 toward intermediate section 58, or vice versa, to axially aligned roles 64 and 66. After receiving the rod,
upon releasing the pushing action, binding relationship is established between the retainer and the rod. In this embodiment, a second hole 67 is provided in end section 56 and end section 54 extends through that hole longitudinally beyond sections 56 and 58. Hole 67 may be considerably larger than the cross section of end section 54. The end of end section 54 provides a support similar to end section 24 in the embodiment shown in FIG. 4; it also can be used as a stop for many purposes, one such purpose being shown in FIG. 7. In that figure, the retainer is used as a stop for a coupling pin 52. A clevis 69 receives a bar 71. The clevis and bar are provided with aligned hole for receiving the pin 52. Should pressure be exerted on the end of end section 54, the intermediate section 58 would be pushed downwardly and thereby enhance the binding relationship between the Walls forming openings 64 and 66 and the pin.
Binding relationship can be released readily by merely pushing end section 56 toward intermediate section 58, or vice versa. Ears 70 are provided for the ready manipulating of section 56.
Referring now to the embodiment shown in FIGS. 8 and 9 which is a modification and includes the characteristics of both previously described embodiments. The retainer 120 includes an end section 124, an end section 126 and three intermediate sections 127, 128 and 130. Sections 124,127, 128 and 130 are'like sections 24, 26, 28 and 30, respectively, of embodiment shown in FIGS. 1 to 4, except that section 128 is provided with a hole 167, like the hole 67 in section 56 of the embodiment shown in FIGS. 5, 6 and 7, and also the end section 126 is a continuation of intermediate section 127 and that end section :xtends through the hole 167. The sections 124, 127 and [28 are provided with axially alignable holes 132, 134 and 136, respectively, for receiving an element such as a pin or rod.
The holes 134 and 136 in intermediate sections are ilightly larger in diameter than the diameter of the element to be received thereby. The hole 132 in end section [24 can be larger in diameter than the diameter of holes [34 and 136. End section 124 extends longitudinally beyond sections 127 and 128, and end section 126 extends .ongitudinally beyond sections 128 and 127.
When it is desirable to fasten the retainer 120 onto, for example, a rod 22, intermediate section 127 is pushed :oward intermediate section 128 to axially align hole 134 .n section 127 with the holes 132 and 136 in sections [24 and 128. The element (rod or pin) is then inserted ;hrough holes 132, 134 and 136. Upon releasing of the :ompressing action, due to the inherent resiliency of the retainer, binding relationship is established between the walls forming the holes 134 and 136 and the rod or pin. Ears 140 are provided on intermediate section 127 for the ready manipulation of the section.
When it is desirable to remove the rod or shift it relazive to the retainer 120, intermediate section 127 is pushed ;oward intermediate section 128, to axially align the former hole with the latter. Then the retainer is moved relative to the rod, or vice versa. 3
In the embodiment shown in FIGS. 8 and 9, either end section forms a stop or support of both end section form stops or supports. Pressure imparted on end section 124 toward intermediate section 128 enhances binding relationship between the wall forming hole 136 and the rod. Pressure imparted on the end of end section 126 toward intermediate section 127 enhances binding relationship between the wall forming opening 134 and the rod.
Thus, from the foregoing it is apparent that retainers have been provided which provide stops on elements such as rods, pins, bolts, wire, etc., or as supports. The construction is such that when pressure is applied, on a stop or support section of the retainer, toward another section of the retainer, binding relationship is enhanced between the retainer and the received element.
Moreover, the retainer is simple in construction, inexpensive and readily operable.
