Interlocking panels

Abstract

Interlocking panels include a frame configured as a perimeter of a panel, the frame including at least one engageable frame portion. The panel defines at least one side opening disposed adjacent the engageable frame portion(s) so that one panel may be attached to another panel by at least one connection means passing through the side opening(s) to capture the engageable frame portion(s).

Description

FIELD OF THE INVENTION

The present invention relates to interlocking panels and, more particularly, it relates to interlocking web panels.

BACKGROUND OF THE INVENTION

A search of the patent art for interlocking panels revealed a number of floor panels having interlocking features. Some of these had modifications of the familiar tongue and groove feature of hardwood floor boards. U.S. Pat. No. 6,862,857, U.S. Pat. No. 8,880,307, and U.S. Pat No. 6,804,926 all employed modified tongue and groove arrangements to attach adjacent panels to each other along their edges.

U.S. Pat. No. 6,174,116 teaches panels that can be oriented vertically to make fence-like structures. The panels can be interlocked orthogonally. They have slots cut half way across their width, the width of the slots being equal to the thickness of the panels. Panels oriented in one direction with the slots upward can receive panels oriented perpendicularly with their slots downward to define rectangular areas. These may be employed in the bed of a truck to provide fenced areas for cargo.

U.S. Pat. No. 6,061,987 teaches sheet panels for easy to assemble structures. One edge of the panels is bent at 90 degrees relatively to the panel. An opposite edge is hemmed to receive the bent edge of another panel.

U.S. Pat. No. 6,769,217 teaches floor panels which may be interconnected by clips which join adjacent panel edges and hold the panels at the same elevation.

Introduction to the Invention

The present invention is an interconnectable panel, preferably including a central web portion. The panels have interconnection features so they can be connected to each other along their edges. They are intended to be used with the versatility of the containers commonly known as “milk crates”. They may be used to protect flowers from animals. They also may be employed by children as construction toys. Another application is for room decoration and remodeling. Preferably, they can be joined either by an in plane connection, or by an orthogonal connection which joins panels at 90 degrees relatively to each other.

SUMMARY OF THE INVENTION

In one aspect, the present invention is a panel including a frame configured as a perimeter of the panel, the frame including at least one engageable frame portion. The panel defines at least one side opening disposed adjacent the engageable frame portion(s) so that one panel may be attached to another panel by at least one connection means passing through the side opening(s) to capture the engageable frame portion(s).

In another aspect, the present invention is a connectable pair of panels, the connectable pair of panels including a first panel including a frame configured as a perimeter of the first panel, the frame including at least one engageable frame portion. There are one or more side openings in the first panel, the side openings disposed adjacent the engageable frame portions of the first panel. The pair also includes a second panel and a connection means configured to pass through the opening in the first panel to capture the engageable frame portion of the first panel and hold the first panel firmly against the second panel.

In an additional aspect, the present invention is a panel including a frame configured as a perimeter of the first panel, the frame including at least three engageable frame portions, the panel defining a side opening disposed adjacent each of the engageable frame portions. A ridge portion of the frame is disposed on a first side of the engageable frame portion and a groove portion of the frame is disposed on a second side of the engageable frame portion so that a second panel identical to the first may be attached to the first panel, a groove portion of the frame of the second panel mating with one of the ridge portions of the frame of the first panel and a ridge portion of the frame of the second panel mating with one of the groove portions of the frame of the first panel; whereby the second panel may be tightly attached to the first panel by a connection means passing through one of the side openings in the first panel and a similar side opening in the second panel.

DETAILED DESCRIPTION OF PREFERRED AND ALTERNATIVE EMBODIMENTS OF THE INVENTION

FIG. 1 illustrates a panel according to one aspect of the present invention. Panel 10 includes a frame 12 configured as a perimeter of panel 10. Frame 12 includes at least one engageable frame portion 15. Panel 10 defines one or more side openings 17, each side opening 17 adjacent an engageable frame portion 15.

Preferably, panel 10 also includes at least one connection means 20 for passing through a side opening 17 of a second panel to capture an engageable frame portion 15 of frame 12 of the second panel. It is preferred that connection means 20 includes a first snap portion 26, and that a second snap portion 28 be attached to frame 12 of panel 10.

Preferably, frame 12 also includes a frame ridge portion 14 or a frame groove portion 16 for engagement with a frame groove portion 16 or frame ridge portion 14 of a second panel.

Preferably, panel 10 includes a web portion 13 disposed within frame 12. Web portion 13 includes web elements 18 defining web openings 19 therebetween.

It is preferred that ridge portion 14 of frame 12 have a cross section 2-2 as shown in FIG. 2. Likewise groove portion 16, preferably, has a cross section 3-3 as shown in FIG. 3.

In an alternative embodiment, shown in FIG. 4, a ridge portion 32 includes two ridges, 34 and 36, oriented at 90 degrees relatively to each other. Thus, a second panel having a groove portion 16 mating with ridge 36 is oriented at a 90 degree angle to the first panel.

FIG. 5 illustrates an alternative ridge portion 38, which is for mating with the alternative groove portion 40 illustrated in FIG. 6.

FIG. 7 illustrates a pair of panels 10 connected together. Preferably, the connection means 20 on the left panel 10 has been passed trough side opening 17 in the right panel 10. The first snap portion 26 is then engaged to the second snap portion 28 on frame 12 of the leftmost panel. The ridge portion 14 of the rightmost panel cannot be seen in this figure because it is received into the groove portion 16 of the leftmost panel.

FIG. 8 illustrates an alternative panel 50 having a frame 52 with an engageable frame portion 55 on each side thereof. Alternative panel 50 defines a side opening 57 adjacent each engageable frame portion 55. Flanking each engageable frame portion 55 is a ridge portion 54 of frame 52 and a groove portion 56 of frame 52. When two similar panels 50 are brought together, as shown in FIG. 10, the ridge portion 54 of each engages the groove portion 56 of the other.

FIG. 9 illustrates a connection means 60 which, preferably is a flexible strap having a first snap portion 64 at one end which is remote from a second snap portion 62 at the other end thereof. Connection means 60 is passed through side opening 57 of both of the panels 50 to capture both of the engageable frame portions 55 and hold the two panels 50 tightly together, after first snap portion 64 is engaged to second snap portion 62. FIG. 10 illustrates the two panels connected by connection means 60.

FIG. 11 illustrates an alternative embodiment of the invention that is intended for inexperienced campers who would like to try sleeping on the ground, but are concerned about small animals and creatures that crawl on the ground. Panel 70 includes frame 12 including an engageable frame portion 15 adjacent a side opening 17. It also includes a connection means 20 so a plurality of panels 70 can be disposed in a line to make a low fence. Preferably, corners in the fence are enabled by perpendicular ridges 36 shown in FIG. 4, that engage groove portions 16 of frame 12.

Panel 70 includes stakes 72 for engagement with the earth. Panel 70 further includes a solid sheet portion 74 having, at its upper edge, a deflector 76, which is for deflecting small crawling creatures. FIG. 12 shows a section cut along 12-12 in FIG. 11, and illustrates the preferred shape of deflector 76.

The presently preferred and alternative embodiments of the present invention having been described herein, it is to be understood that the invention may be otherwise embodied within the scope of the appended claims.
