3 Claims. ((11. 20-95) This invention relates to a framing connector and more particularly to a connector for the posts and rails oi wooden framing, as used in pallet stackers and the li e.

There are many types of framing in which it is desirable to connect rails in a rectangular or other closed section framework to posts for temporary or semi-permanent framing. One example, is in pallet stackers in which vertical posts mounted at the corners of pallets are connected at their upper ends by horizontal rails to form a framework on which additional pallets can be stacked.

It is desirable for uses of this character to be able to use lengths of standard materials such as 2 x 4 or 2 x 2 wooden strips. It is also desirable to be able to assemble such strips into the framework without nailing or cutting to special shapes and to be able to reuse the strips.

It is one of the objects of the present invention to provide a framing connector which will connect standard wooden strips securely in a framework without the use of nails or like fastenings and 'without requiring special cutting of the strips.

Another object is to provide a framing connector in which the ends of the posts and rails are securely gripped in the assembly and are removable for reuse.

According to a feature of the invention, the connector is formed of a minimum number of sheet metal stamp ings assembled by welding, or the like, to provide a socket to fit securely over the end of a post and two pairs of spaced walls facing at an angle to each other to receive between the walls of each pair the end of a rail.

A further object is to provide a framing connector in which the walls are formed with integrally pressed out lip portions to grip the posts and rails.

The above and other objects and features of the invention will be more readily apparent from the following description when read in connection with the accompanying drawing, in which:

Figure 1 is a perspective vie-w of a pallet stacker assembly employing a framing connector embodying the invention;

Figure 2 is a perspective 'view of the framing connector; and

Figure 3 is a disassembled view showing the stampings of which the framing connector is formed.

The framing connector is illustrated in connection with a stacker for use with conventional wooden pallets formed by spaced stringers connected by face boards 11 on which merchandise of any desired type may be supported. The pallet is provided adjacent each corner with a shoe indicated generally at 12. Each shoe is formed with an upwardly facing socket 13 in which a vertical corner post is supported.

As shown, the posts 14 are lengths of conventional 2 x 4 timber cut to the desired length to provide the desired spacing between pallets and are fitted tightly into the sockets 13 to be held in vertical position thereby. The shoes are left and right hand so that the widths of the posts 14 all extend in the same direction for convenience of loading.

At their upper ends the posts 14 are connected by horizontal rails 15 which are also cut lengths of standard timbers. The rails may be 2 x 4s or may, if preferred, be 2 x 2s. If 2 x 4s are employed, they are mounted with their wide dimension vertically so that in either case the horizontal width of the rail will be the standard finished width of 2." timber or 1%".

The connector of the present invention is adapted to secure the rails to the posts in a manner such that the rails will be held securely, but can be removed for re use. As illustrated in Figure 3, the connector is made up of three stampings constituting two

side stampings

16 and 17 and a center stamping 18. The stamping 16 is provided throughout approximately its lower half with parallel flanges 19 and at its upper half is formed with a flange 21 coplanar with one of the flanges 19, but of substantially double its length. In its flat portion between the flanges 19 the sheet is formed with parallel slits and the metal is pressed out between the slits to form a pair of tongues 22 fastened at their ends to the sheet and projecting beyond the surface of the sheet between their ends for gripping. In its upper part, the sheet is formed with a similar lip 23 near the edge of the central plate portion and with a lip 24 in the flange 21. Also substantially midway of the width of the central plate portion there is provided a slot 25 for a purpose to appear later.

The stamping 17 is similar in its lower portion to the stamping 16, being formed with spaced flanges 26 and with pressed-in lips 27. In its upper portion, the plate is bent substantially midway of its width to define a flange 28. The upper web portion of the stamping 17 is formed with a lip 29 and a similar lip may be provided in the flange 28, as shown at 31. The outer end of the flange 28 is provided with a lug 32 of a size to fit into the slot 25 in the stamping 16.

The center piece 18 is in the form of a flat strip of a length equal to the width of a standard 2 x 4 and a width equal to the thickness of a standard 2 X 4. At its ends, the plate is bent down into flanges 33 which are relatively short, as shown.

To assemble the connector pieces are brought together in a relationship shown in Figures 2 and 3 with the central plate 18 resting on the tops of the

flanges

19 and 26 and with the flanges 33 on the plate overlying the

flanges

19 and 26, as seen in Figure 2. To complete the assembly, the flanges 33 may be welded at their edges to the

flanges

19 and 26, as indicated at 34. Also, the lug 32 where it projects through the slot 25 may be welded to the stamping 16. This operation completes assembly of the unit and can be performed very simply.

In the completely assembled connector, as shown in Figure 2, the lower portions of the two stampings, together with their

flanges

19 and 26, provide a downwardly opening socket to receive the upper end of a post 14. The parts are sized so that the post will fit very snugly in the socket and when the socket is forced over the end of the post the

lips

22 and 27 will bite into the wood of the post to hold it securely thereon. To facilit-ate removal, the stamping 17 may be formed with a pressed-out boss 35 at its lower edge which can be struck by hammer to drive the connector off of the post. It has been found that with a connector, as so far described, the mounting on the post will be extremely rigid and secure, requiring a considerable degree of force for removal. However, since the end of the post is deformed only by the

lips

22 and 27, the post can be reused a number of times with the same security of attachment to the connector.

At the upper end of the connector above the plate 18,

the portions of the stampings define two pairs of spaced walls. Thus the body or web portions of the stampings include a wall portion 36 and a wall portion 37 spaced apart the width of the center plate 18 to receive tightly between them a standard 2 x 2 or a standard 2 x 4 fitted in edgewise. Similarly, the flanges 21 and 28 form a pairof spaced wall portions at right angles to the

wall portions

36 and 37 to receive the end of a standard 2 x 2 or 2 x 4 rail. To assemble the rails, the ends may be placed above the partial sockets defined by the pairs of spaced wall portions and driven downwardly into the sockets. During this operation, the

lips

23, 24, 29 and 31 will bite into the end portions of the rails to anchor them securely in place.

. In a complete assembly, as shown in Figure 1, the connectors must be right and left hand so that the upper partial sockets will face toward each other to receive opposite ends of a rail extending between the tops of adjacent posts. For some assemblies, however, in which the posts are square, connectors of a single hand can be used satisfactorily.

When the posts and rails are assembled by the connectors, as shown in Figure 1, they form an extremely strong and rigid framework on which additional pallets can be stacked or which can be used for other desired purposes. When it is desired to disassemble the framework, the rails may be driven out of the upper partial sockets by a hammer or mallet and the connectors can be detached from the posts by hammering on the bosses 35. The framework can therefore be easily assembled and disassembled simply by the use of a conventional hammer or mallet and with no other tools or permanent fastenings.

While one embodiment of the invention has been shown and described herein, it will be understood that it is illustrative only and not to be taken as a definition of the scope of the invention, reference being had for this purpose to the appended claims.
