Definitions
- connection between panels has been to form at the edges of the panels, loops or hooks which may be aligned with similar loops or hooks on adjacent panels.
- the panel loops may then be locked in this relatively aligned position by means of a rod driven therethrough.
- this type connection necessitates a separate and special wire forming operation which adds to the cost of the unit.
- some fabricators have resorted to the welding of the loops while others have provided the special clips which serve to prevent the loops from opening under tension.
- difficulty may be encountered in aligning some of the loops so that the rod may be inserted.
- the improved fastener constructed in accordance with this invention is for use in combination with a pair of reticulated metal (i.e., wire or bar mesh) panels.
- Each panel comprises two transversely disposed sets of parallel wire or barlike elements.

- the panels are disposed in partial overlapping registration and are similarly oriented, so that their corresponding aligned superposed elements of the panels are spaced apart by the transversely disposed other element or elements of the overlapping panel.
- This orientation also places the vertical element of one of the panels in contiguous relationship with the horizontal element of the other panel.
- the horizontal elements are considered the superposed elements.
- the panels are normally subjected to forces tending to separate the panels in a direction parallel to the extent of the superposed elements.
- the fastener used to unite these partially overlapped panels comprises a member formed of a single bar and bent approximately at its midpoint to form a bight with a pair of similarly shaped substantially coextensive legs extending therefrom.

- the horizontal and vertical elements are welded together to form a strong rigid panel structure.
- the elements be impressed into each other, as illustrated in FIGS. 2 and 3. This provides a very strong and laterally stable panel structure and is utilized to best advantage in this invention, as will be hereinafter more fully described.
- the thickness of each panel is thus preferably slightly less than the sum of the diameters of one vertical element and one horizontal element.
- the vertical panel elements 12 and 14 may, for example, be spaced apart approximately 2 inches, respectively, whereas the horizontal panel elements 13 and 15 may be spaced about 6 inches apart, respectively.
- the ends of the horizontal panel elements 13 and 15 overextend the end vertical elements 12 and 14, so that once the panels are joined by the fasteners 20, as will be described, the panels cannot be pulled apart sufliciently to effect disengagement of these panel element ends from either the panel elements 14 or the ends of the fasteners 20.
- the gauge of the wire or red from which the panels 10 and 11 are constructed will vary according to the application. For example, it is preferred that #4 to gauge wire be used for corn crib structures, although in some instances it may be desired to use heavier or lighter gauge. For the purpose of this description the terms wire" and rod are considered equivalents and may be used interchangeably.
- the panels are arranged in slightly overlapping relationship, and they are similarly oriented, that is, the vertical elements 12 and 14 are disposed on the same side of their respective horizontal elements 13 and 15.
- the horizontal elements 13, which in this instance are the superposed elements, of panel are in registration with the horizontal elements 15, which in this instance are the superposed elements, of the panel 11 (see FIGS. 1 and 3), and the end vertical or other elements of the panels are also in registration (see FIG. 2).
- the fastener is adapted to join these two thus oriented and partially overlapped and registered panels.
- the fastener 20 comprises an integral rodlike member which may be of the same gauge as the panel elements 12-15. Actually because of the novel design, the fastener member may be of somewhat lighter gauge than the panel elements.
- the member is bent at approximately its mid portion to form a bight 22 and a pair of integral, substantially coextensive, similarly shaped legs 24 and 26, the spacing between the legs being uniform and slightly greater than the diameter of the panel elements.
- the bight 22 effectively closes one end of the fastener member, whereas the other end of the fastener member is open. Adjacent the open end of the member each of the legs 24 and 26 is provided with a hook portion 24a and 26a, respectively, and these hook portions are aligned.
- the legs extend laterally and are bent through an acute angle of greater than about 35 degrees and preferably between about 40 and about 50 degrees to form knee portions 241; and 26b, respectively, which are also aligned.
- the radius of the bend at the bight 22 and at the knee portions 245 and 26b is preferably equal to or slightly greater than the radius of the panel elements 1215.
- the lateral extension of the knees 24b and 26b is suflicient to permit the knees to extend about the vertical panel element 12 of panel 10 when the horizontal panel element 15 is disposed within the closed end or bight 22 (see FIG. 2).
- the effective lateral extension or offset of the knees with respect to the bight may be measured along a plane which would bisect the knees 24b and 26b, and it is the distance between the interior of the knees and a plane which would be perpendicular to the knee-bisecting plane and would pass through the interior of the bight 22. It will be noted from FIGS.
- this effective lateral extension of the knees with respect to the bight is slightly greater than the distance between that plane defined by the outermost parts of elements 12 and that plane defined by the outermost parts of panel elements 15. This distance may also be defined as the sum of the thicknesses of the two panels. In order to provide a tight engagement of the panel elements by the fastener, the effective lateral extension of the knees should be approximately equal to (or slightly greater than) the thickness of the lap.
- the distance between the closed end or bight 22 and the portion of legs connecting the knees and hook portions is slightly greater than the sum of the thicknesses of the two panels. This feature permits the fastener to be easily swung about the panel elements as illustrated in FIG. 4 until positioned as shown in FIG. 5. It will be noted that the distance between the knees 2411-2612 and the hook portions 24a-26a is greater than the distance between the knees and the bight 22, and thus when the fastener member is fully positioned about the panel elements, as illustrated in FIG. 4, the hook portions will extend outwardly from the plane defined by the outermost parts of the panel elements 15.
- a pin 30 is provided.
- This pin preferably has an enlarged head portion 30a and a protruberant portion 30b spaced from the head 30a a distance which is slightly greater than the distance through the hook portions 24a and 26a.
- the tip of the pin may be tapered to facilitate initial insertion of the pin through the hook portions 24a and 26a.
- the effective relative lateral offset distance between the knees 24b26b and the hook portions 24a-26a as measured along a line which would bisect the knees is the distance between the interior of the knees and a plane which would be perpendicular to the knee-bisecting plane and would pass through the interior of the hook portions. This distance is slightly greater than the sum of the thicknesses of the two panels 10 and 11 and the diameter of the pin 30. As a result of this, when the pin 30 is inserted through the hook portions 2411-2612, this pin will be held against the horizontal element 15, and the protuberance 30b will prevent the pin from being accidentally removed.
- FIG. 5 there is illustrated a pair of vertically adjacent fasteners.
- the pin 30 In the top fastener the pin 30 has already been inserted through the hook portions 24a and 2611, whereas in the bottom fastener the pin is in position for insertion through these hook portions. After a pin has been inserted it is resiliently held in place by the head 30a at the top and by the protuberant formation 30b at the bottom. Because of the orientation of the panels 12 and 14 and the structure of the fastener, the action of the fastener on the panels is such that the welds will be under compression rather than tension at the joint.
- the panels are normally subjected to forces ten-ding to separate them in a direction parallel to the extent of the superposed sets of elements (for example, in this instance in the horizontal direction as viewed in FIG. 1). Any forces tending to pull the two panels apart causes the clip to actually clamp the panel elements tightly together, acting, of course, on the horizontally extending exterior panel element 15 of panel 11 and on the vertically extending exterior panel element 12 of panel 10.
- the panel elements 12 and 14 are restricted in their relative lateral movement by virtue of their disposition within the lateral knee-forming extension of the legs. Forces tending to pull the panels apart will thus be resisted by the compressive forces exerted by the clip tending to hold the welded ports together and by the shear strength of the panel element welds. Since the panel elements are impressed into each other as previously described, this shear strength is substantially increased.
- a fastener 20 be provided at each of the junctures of the horizontal elements 13 and 15. If desired, the fasteners may also be employed to join panels which are arranged vertically or which are laid flatly. The connection between the fastener and the panels 10 and 11 has been found to be at least as strong as the panels themselves, even though the clip may be made of wire or rod which is of lighter gauge than that which is used to form the panel elements.
- the panels 12 and 14 are constructed without any forming or bending operations such as might be required to form end loops which were heretofore commonly used to unite adjacent panel-s.
- the fasteners used to unite the adjacent panels may be manufactured easily and inexpensively on automatic machinery, and when'in place the fasteners provide an exceptionally strong joint.

PANEL ASSEMBLY AND FASTENER Filed April 25, 1962 INVEN TOR.
United States Patent O M 3,220,518 PANEL ASSEMBLY AND FASTENER Wiliiam Stanton Deming, 605 Can Dota St., Mount Prospect, Ill. Filed Apr. 25, 1962, Ser. No. 190,037 Claims. (Cl. 189-36) This invention relates to a panel assembly and to an improved fastener or clip for uniting wire or bar mesh panels. The joined panels may be used in the construction of such items as corn cribs, wire mesh fencing, reinforcing mesh, hog pens, farrowing pens, and so forth.
In constructing a unit such as a corn crib of a plurality of wire or bar mesh panels, it is necessary that the panels be firmly interconnected so that the structure will be strong and able to withstand all of the forces which it may be expected to encounter. Speed and ease of erection are also highly desirable characteristics for such a unit, and since it is oftimes desirable to relocate such a unit facility of disassembly is considered to be an important factor.
One means for accomplishing the connection between panels has been to form at the edges of the panels, loops or hooks which may be aligned with similar loops or hooks on adjacent panels. The panel loops may then be locked in this relatively aligned position by means of a rod driven therethrough. From the fabricators standpoint this type connection necessitates a separate and special wire forming operation which adds to the cost of the unit. Moreover, in order to strengthen this connection, some fabricators have resorted to the welding of the loops while others have provided the special clips which serve to prevent the loops from opening under tension. Additionally, since several sets of loops are sometimes traversed by a single lock rod, difficulty may be encountered in aligning some of the loops so that the rod may be inserted.
It is, therefore, one object of this invention to provide an improved reticulated metal panel assembly.
It is another object of this invention to provide a fastener which may be used to firmly join reticulated metal panels in overlapping relationship.
It is a further object of this invention to provide an exceptionally strong fastener which may be quickly and easily applied to unite adjacent wire or bar mesh panels and which may be easily removed to facilitate disassembly of the panels.
It is an additional object of this invention to provide a fastener which will lock two reticulated metal panels together without requiring the panels to have end loops and without necessitating the use of special tools to effect alignment of portions of the panels during assembly.
It is a still further object of this invention to provide a joint between adjacent wire or bar mesh panels which is as strong as the panels themselves.
It is an additional object of this invention to provide a very strong fastener which can be quickly and inexpensively manufactured and which may be quickly and easily applied to the panels to effect the joining thereof.
It is still another object of this invention to provide a reticulated metal panel structure employing a novel fastener which materially reduces the cost of the structure and greatly facilitates the erection thereof.
Other objects will be seen, and a further understanding of the invention may be had by referring to the following description and claims taken in conjunction with the accompanying drawing.
The improved fastener constructed in accordance with this invention is for use in combination with a pair of reticulated metal (i.e., wire or bar mesh) panels. Each panel comprises two transversely disposed sets of parallel wire or barlike elements. One set of elements extends 3,220,518 Patented Nov. 30, 1965 horizontally, and the other, vertically; and one of the sets of elements is superposed on the other set, and the sets are joined usually by welding. In order to effect the uniting of two adjacent panels, the panels are disposed in partial overlapping registration and are similarly oriented, so that their corresponding aligned superposed elements of the panels are spaced apart by the transversely disposed other element or elements of the overlapping panel. This orientation also places the vertical element of one of the panels in contiguous relationship with the horizontal element of the other panel. In the illustrated embodiment the horizontal elements are considered the superposed elements. The panels are normally subjected to forces tending to separate the panels in a direction parallel to the extent of the superposed elements.
The fastener used to unite these partially overlapped panels comprises a member formed of a single bar and bent approximately at its midpoint to form a bight with a pair of similarly shaped substantially coextensive legs extending therefrom. Thus, the member is closed at the one end and open at the other. The legs have aligned hook portions adjacent the open end, and intermediate the bight and the hook portions are laterally extending aligned knee portions. The fastener is positioned with respect to the partially overlapped panels such that a superposed element of one of the overlapping one of the panels at the lap is disposed within the closed end or bight of the member, and the knee portions of the legs extend about an adjacent element of the other of said sets of elements of the other of said panels at the lap. The hook portions of the legs are disposed outwardly of the superposed panel element of said overlapping panel, and a pin is disposed within and traverses these hook portions in order to lock the member in position.
In this manner, a very strong joint may be quickly formed between adjacent panels without the necessity of wire loops in the panels and without additional clamping, welding or reinforcing.
With reference to the drawing:
FIGURE 1 is a perspective view of portions of two panels showing the relationship between the panel ele ments and showing the fastener employed to join these panels in accordance with this invent-ion;
FIG. 2 is a top plan view of the panel portions illustrated in FIG. 1;
FIG. 3 is a sectional elevation view of the panels taken substantially along line 3-3 of FIG. 2;
FIG. 4 is a perspective view showing the manner in which a fastener may be applied to the overlapping panels; and
FIG. 5 is a perspective view showing two adjacent fasteners, one of which has the pin inserted within the aligned hook portions of the legs and the other of which has the pin in position for insertion.
With further reference to the drawing, and particularly to FIG. 1, there are shown portions of two panels 10 and 11 formed of a heavy wire or rod arranged in a grid pattern. Panel 10 consists of a plurality of parallel elements 12 which are illustrated as extending in the vertical direction and a plurality of parallel elements 13 which traverse the vertical panel elements 12 on one side thereof and are illustrated as extending in the horizontal direction. Panel 11 is identically constructed consisting of a set of vertical elements 14 and a set of horizontal elements 15 disposed to one side of the vertical elements. In each panel the horizontal and vertical elements are welded together to form a strong rigid panel structure. In the process of welding the horizontal and vertical panel elements, it is preferred that the elements be impressed into each other, as illustrated in FIGS. 2 and 3. This provides a very strong and laterally stable panel structure and is utilized to best advantage in this invention, as will be hereinafter more fully described. The thickness of each panel is thus preferably slightly less than the sum of the diameters of one vertical element and one horizontal element.
The vertical panel elements 12 and 14 may, for example, be spaced apart approximately 2 inches, respectively, whereas the horizontal panel elements 13 and 15 may be spaced about 6 inches apart, respectively. The ends of the horizontal panel elements 13 and 15 overextend the end vertical elements 12 and 14, so that once the panels are joined by the fasteners 20, as will be described, the panels cannot be pulled apart sufliciently to effect disengagement of these panel element ends from either the panel elements 14 or the ends of the fasteners 20. The gauge of the wire or red from which the panels 10 and 11 are constructed will vary according to the application. For example, it is preferred that #4 to gauge wire be used for corn crib structures, although in some instances it may be desired to use heavier or lighter gauge. For the purpose of this description the terms wire" and rod are considered equivalents and may be used interchangeably.
It is to be noted from FIGS. 1 and 2 that the panels are arranged in slightly overlapping relationship, and they are similarly oriented, that is, the vertical elements 12 and 14 are disposed on the same side of their respective horizontal elements 13 and 15. The horizontal elements 13, which in this instance are the superposed elements, of panel are in registration with the horizontal elements 15, which in this instance are the superposed elements, of the panel 11 (see FIGS. 1 and 3), and the end vertical or other elements of the panels are also in registration (see FIG. 2). The fastener is adapted to join these two thus oriented and partially overlapped and registered panels.
The fastener 20 comprises an integral rodlike member which may be of the same gauge as the panel elements 12-15. Actually because of the novel design, the fastener member may be of somewhat lighter gauge than the panel elements. The member is bent at approximately its mid portion to form a bight 22 and a pair of integral, substantially coextensive, similarly shaped legs 24 and 26, the spacing between the legs being uniform and slightly greater than the diameter of the panel elements. The bight 22 effectively closes one end of the fastener member, whereas the other end of the fastener member is open. Adjacent the open end of the member each of the legs 24 and 26 is provided with a hook portion 24a and 26a, respectively, and these hook portions are aligned. Intermediate the closed end and the hook portions 24a and 26a, the legs extend laterally and are bent through an acute angle of greater than about 35 degrees and preferably between about 40 and about 50 degrees to form knee portions 241; and 26b, respectively, which are also aligned.
The radius of the bend at the bight 22 and at the knee portions 245 and 26b is preferably equal to or slightly greater than the radius of the panel elements 1215. The lateral extension of the knees 24b and 26b is suflicient to permit the knees to extend about the vertical panel element 12 of panel 10 when the horizontal panel element 15 is disposed within the closed end or bight 22 (see FIG. 2). The effective lateral extension or offset of the knees with respect to the bight may be measured along a plane which would bisect the knees 24b and 26b, and it is the distance between the interior of the knees and a plane which would be perpendicular to the knee-bisecting plane and would pass through the interior of the bight 22. It will be noted from FIGS. 2 and 3 that this effective lateral extension of the knees with respect to the bight is slightly greater than the distance between that plane defined by the outermost parts of elements 12 and that plane defined by the outermost parts of panel elements 15. This distance may also be defined as the sum of the thicknesses of the two panels. In order to provide a tight engagement of the panel elements by the fastener, the effective lateral extension of the knees should be approximately equal to (or slightly greater than) the thickness of the lap.
Also, the distance between the closed end or bight 22 and the portion of legs connecting the knees and hook portions is slightly greater than the sum of the thicknesses of the two panels. This feature permits the fastener to be easily swung about the panel elements as illustrated in FIG. 4 until positioned as shown in FIG. 5. It will be noted that the distance between the knees 2411-2612 and the hook portions 24a-26a is greater than the distance between the knees and the bight 22, and thus when the fastener member is fully positioned about the panel elements, as illustrated in FIG. 4, the hook portions will extend outwardly from the plane defined by the outermost parts of the panel elements 15.
In order to lock the member in its position in engagement with the panel elements, a pin 30 is provided. This pin preferably has an enlarged head portion 30a and a protruberant portion 30b spaced from the head 30a a distance which is slightly greater than the distance through the hook portions 24a and 26a. The tip of the pin may be tapered to facilitate initial insertion of the pin through the hook portions 24a and 26a.
The effective relative lateral offset distance between the knees 24b26b and the hook portions 24a-26a as measured along a line which would bisect the knees is the distance between the interior of the knees and a plane which would be perpendicular to the knee-bisecting plane and would pass through the interior of the hook portions. This distance is slightly greater than the sum of the thicknesses of the two panels 10 and 11 and the diameter of the pin 30. As a result of this, when the pin 30 is inserted through the hook portions 2411-2612, this pin will be held against the horizontal element 15, and the protuberance 30b will prevent the pin from being accidentally removed.
In FIG. 5 there is illustrated a pair of vertically adjacent fasteners. In the top fastener the pin 30 has already been inserted through the hook portions 24a and 2611, whereas in the bottom fastener the pin is in position for insertion through these hook portions. After a pin has been inserted it is resiliently held in place by the head 30a at the top and by the protuberant formation 30b at the bottom. Because of the orientation of the panels 12 and 14 and the structure of the fastener, the action of the fastener on the panels is such that the welds will be under compression rather than tension at the joint. The panels are normally subjected to forces ten-ding to separate them in a direction parallel to the extent of the superposed sets of elements (for example, in this instance in the horizontal direction as viewed in FIG. 1). Any forces tending to pull the two panels apart causes the clip to actually clamp the panel elements tightly together, acting, of course, on the horizontally extending exterior panel element 15 of panel 11 and on the vertically extending exterior panel element 12 of panel 10. The panel elements 12 and 14 are restricted in their relative lateral movement by virtue of their disposition within the lateral knee-forming extension of the legs. Forces tending to pull the panels apart will thus be resisted by the compressive forces exerted by the clip tending to hold the welded ports together and by the shear strength of the panel element welds. Since the panel elements are impressed into each other as previously described, this shear strength is substantially increased.
It is preferred that a fastener 20 be provided at each of the junctures of the horizontal elements 13 and 15. If desired, the fasteners may also be employed to join panels which are arranged vertically or which are laid flatly. The connection between the fastener and the panels 10 and 11 has been found to be at least as strong as the panels themselves, even though the clip may be made of wire or rod which is of lighter gauge than that which is used to form the panel elements.
It may be seen that the panels 12 and 14 are constructed without any forming or bending operations such as might be required to form end loops which were heretofore commonly used to unite adjacent panel-s. The fasteners used to unite the adjacent panels may be manufactured easily and inexpensively on automatic machinery, and when'in place the fasteners provide an exceptionally strong joint. These fasteners may be applied quickly and easily to the panels, and they may be easily removed for disassembly of the panels to permit removal and relocation thereof.
Although the invention has been described With a certain degree of particularity, it is understood that the present disclosure has been made only by way of example and that many modifications and changes in various details may be resorted to without departing from the spirit and scope of the invention, as hereinafter claimed.
What is claimed is:

In combination, a pair of panels, each panel comprising tWo transversely disposed and joined similar sets of parallel elements, one of said sets being superposed on the other of said sets, said panel-s being disposed in partial overlapping registration and similarly oriented and subjected to forces tending to separate the panels in a direction parallel to the extent of the superposed sets of elements, a member having a pair of legs spaced to accommodate a panel element therebetween and joined to effect closing of said member adjacent one end thereof, said legs having aligned hook portions adjacent their free ends and laterally extending aligned knee portions intermediate said hook portions and said closed end, a superposed element of the overlapping one of said panels at the lap being disposed within the closed end of said member, the knee portions of said member extending about an adjacent element of the other of said sets of elements of the other of said panels at the lap, and the hook portions of said member being disposed outwardly of said superposed panel element of the overlapping one of said panels, and a pin disposed within and extending between the hook portions of said member whereby said member may be locked in position, the distance between said knee and a plane which passes through the interior of said hook portion and is perpendicular to a plane bisecting said knees being slightly greater than the sum of the thicknesses of said panels and the diameter of said pin.
2. In combination, a pair of panels, each panel comprising two transversely disposed and joined similar sets of parallel elements, one of said sets being superposed on the other of said sets, said panels being disposed in partial overlapping registration and similarly oriented and subjected to forces tending to separate the panels in a direction parallel to the extent of the superposed sets of elements, a member having a pair of legs spaced to accommodate a panel element therebetween and joined to effect closing of said member adjacent one end thereof, said legs having aligned hook portions adjacent their free ends and laterally extending aligned knee portions intermediate said hook portions and said closed end, the distance between said knees and a first plane which passes through the interior of said closed end and is perpendicular to a plane bisecting said knee being slightly greater than the sum of the thicknesses of said two panels, a superposed element of the overlapping one of said panels at the lap being disposed Within the closed end of said member, the knee portions of said member extending about an adjacent element of the other of said sets of elements of the other of said panels at the lap, and the hook portions of said member being disposed outwardly of said superposed panel element of the overlapping one of said panels, and a pin disposed within and extending between the hook portions of said member, whereby said member may be locked in position, the distance between said knees and a plane which passes through the interior of said hook portion and is perpendicular to a plane bisecting said knees being slightly greater than the sum of the thicknesses of said panels and the diameter of said pin.
3. The structure of claim 2 wherein said pin is provided with an enlarged head portion and a protuberant section spaced from said head portion a distance greater than the thickness of said member, whereby said pin may be releasably locked in position traversing the hook portions of said member.
4. In combination, a pair of panels, each panel comprising two transversely disposed and joined similar sets of parallel element-s, one of said sets being superposed on the other of said sets, said panels being disposed in partial overlapping registration and similarly oriented and subjected to forces tending to separate the panels in a direction parallel to the extent of the superposed sets of elements, a member formed of a single elongated rod bent at approximately its midpoint to form a closed end bight and a pair of substantially coextensive uniformly spaced legs extending therefrom and adapted to accommodate aligned panel elements therebetween, said legs having aligned hook portions adjacent their free ends and laterally extending aligned knee portions intermediate said hook portions and said closed end, a superposed element of the overlapping one of said panels at the lap being disposed within the closed end of said member, the knee portions of said member extending about an adjacent element of the other of said sets of elements of the other of said panels at the lap, and the hook portions of said member being disposed outwardly of said superposed panel element of the overlapping one of said panels, and a pin disposed within and extending between the hook portions of said member, whereby said member may be locked in position and said panels may be held firmly in overlapping relationship.
5. In combination, a pair of panels, each panel comprising two transversely disposed and joined similar sets of parallel elements, one of said sets being superposed on the other of said sets, said panels being disposed in partial overlapping registration and similarly oriented and subjected to forces tending to separate the panels in a direction parallel to the extent of the suporposed sets of elements, and a fastener comprising an elongate member having means adjacent each end thereof for engaging a superposed element of the overlapping one of said panels at the lap and an intermediate laterally extending knee portion extending about an adjacent element of the other of said sets of elements of the other of said panels at the lap, whereby said panels may be interlocked in overlapping relationship.
