Abstract

A packing insert is shown, which includes a first face, a second face, opposite the first face, a first side support and a second side support. The first side support is flexibly connected to the first face and the second face, preferably to one edge of each face. When not fully extended, the side supports bend inwards between the first face and the second face. The first side support and the second side support are in positions with respect to the first face and the second face and each other such that when they are bent inwards between the first face and the second face, the first support member does not interfere with the second support member. In a preferred arrangement, the first side support is flexibly connected to the first face and the second face at a position which is different from that of the second side support, so that when the first side support and the second side support are bent inwards sufficiently far, they pass each other without interfering with each other.

The forward support member and the rear support member are rotatably connected to each other at their ends which are opposite the first face and the second face. In one arrangement, each side support includes a multi-position locking hinge rotatably connecting the forward support member to the rear support member. In another arrangement, each side support includes a cam-locking hinge rotatably connecting the forward support member to the rear support member. In yet another arrangement, each side support includes a tension spring hinge rotatably connecting the forward support member to the rear support member.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to packing boxes and file drawers.

2. Description of Related Art

Previous packing inserts fall mainly into three classes: those with comer inserts, those which grip the sides of the container and those with inward folding sides: U.S. Pat. No. 0,974,871, PACKING OR SHIPPING BOX (Ferres), FIGS. 8 and 12; U.S. Pat. No. 0,987,958, PACKING OR SHIPPING BOX (Clenny et al.), FIGS. 7, 8 and 9; and U.S. Pat. No. 2,742,219, ACCORDION PLEATED CUSHIONING STRIP (Van Antwerpen). All of the patents with inwardly folding sides have sides which are essentially full height (or length) and are aligned with the other sides rather than offset. They all seem to keep in place through outside pressure rather than a locking mechanism.

U.S. Pat. No. 3,221,973, SPACER PAD (Kalbrener) shows various legs are offset from each other, although they are not opposite each other like the inwardly folding sides of the present invention.

SUMMARY OF THE INVENTION

A packing insert according to the present invention includes a first face, a second face, opposite the first face, a first side support and a second side support. The first side support is flexibly connected at one end to the first face, preferably to one edge, and is flexibly connected at the opposite end to the second face, preferably at one edge. The second side support is flexibly connected at one end to the first face opposite the connection to the first side support, and preferably to the edge of the first face which is opposite the edge connected to the first side support and is flexibly connected at the opposite end to the second face opposite the connection of the first side support, and preferably to the edge of the second face which is opposite the edge connected to the first side support. When not fully extended, the side supports bend inwards between the first face and the second face.

The first side support and the second side support are in positions with respect to the first face and the second face and each other such that when they are bent inwards between the first face and the second face, the first support member does not interfere with the second support member. In a preferred arrangement, the first side support is flexibly connected to the first face and the second face at a position which is different from that of the second side support, so that when the first side support and the second side support are bent inwards sufficiently far, they pass each other without interfering with each other.

In one preferred arrangement, the first side support includes a forward support member flexibly connected at one end to one edge of the first face and a rear support member flexibly connected at one end to one edge of the second face. The forward support member and the rear support member are rotatably connected to each other at their ends which are opposite the first face and the second face. Similarly, the second side support includes a forward support member flexibly connected at one end to the edge of the first face which is opposite the edge connected to the first side support and a rear support member flexibly connected at one end to the edge of the second face which is opposite the edge connected to the first side support. The forward support member and the rear support member are rotatably connected to each other at their ends which are opposite the first face and the second face.

In one arrangement, the first side support further includes a multi-position locking hinge rotatably connecting the forward support member to the rear support member. In a preferred form, the second side support also includes a multi-position locking hinge rotatably connecting the forward support member to the rear support member. In another arrangement, the first side support includes a cam-locking hinge rotatably connecting the forward support member to the rear support member. In a preferred form, the second side support also includes a cam-locking hinge rotatably connecting the forward support member to the rear support member. In yet another arrangement, the first side support includes a tension spring hinge rotatably connecting the forward support member to the rear support member. Again, in a preferred form, the second side support also includes a tension spring hinge rotatably connecting the forward support member to the rear support member.

These and other objects, advantages and features of this invention will be apparent from the following description taken with reference to the accompanying drawing, wherein is shown a preferred embodiment of the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring now to the drawing, and in particular to FIG. 1 and FIG. 2, a packing insert according to the present invention is referred to generally by [0017] reference numeral 10, and it includes a first face 12, a second face 14, opposite the first face, a first side support 16 and a second side support 18. The first side support is flexibly connected at one end to the first face, preferably to one edge 20 of the first face and is flexibly connected at the opposite end to one edge 22 of the second face. The second side support is flexibly connected at one end to the first face opposite the connection to the first side support, and preferably to the edge 24 of the first face which is opposite the edge connected to the first side support and is flexibly connected at the opposite end to the edge 26 of the second face which is opposite the edge connected to the first side support. When not fully extended, the side supports bend inwards between the first face and the second face.
[0018] First side support 16 and second side support 18 are in positions with respect to first face 12 and second face 14 and each other such that when they are bent inwards between the first face and the second face, the first support member does not interfere with the second support member. In the case illustrated, first side support 16 is connected to the top of the two faces, and second side support 18 is connected to the bottom of the two faces. Each side support is less than half the height of the faces, so that side support 16 passes over the top of side support 18 without hitting it or otherwise interfering with its operation. In a preferred arrangement, the first side support is flexibly connected to the first face and the second face at a position which is different from that of the second side support, so that when the first side support and the second side support are bent inwards sufficiently far, they pass each other without interfering with each other. Referring also to FIG. 4, this allows packing insert 10 to be folded flat for storage purposes or for when a box or file drawer is nearly full.
In one preferred arrangement, [0019] first side support 16 includes a forward support member 28 flexibly connected at one end to edge 20 of the first face and a rear support member 30 flexibly connected at one end to edge 22 of the second face. The forward support member and the rear support member are rotatably connected to each other at their ends which are opposite the first face and the second face. Similarly, second side support 18 includes a forward support member 32 flexibly connected at one end to edge 24 of the first face which is opposite the edge connected to the first side support and a rear support member 34 flexibly connected at one end to edge 26 of the second face which is opposite the edge connected to the first side support. The forward support member and the rear support member are rotatably connected to each other at their ends which are opposite the first face and the second face.
Referring also to FIG. 3, in one arrangement, the first side support further includes a [0020] multi-position locking hinge 36 rotatably connecting the forward support member to the rear support member. In a preferred form, the second side support also includes a multi-position locking hinge rotatably connecting the forward support member to the rear support member. In another arrangement, referring to FIG. 5, the first side support includes a cam-locking hinge 38 rotatably connecting the forward support member to the rear support member. In a preferred form, the second side support also includes a cam-locking hinge rotatably connecting the forward support member to the rear support member. In yet another arrangement, referring to FIG. 6, the first side support includes a tension spring hinge 40 rotatably connecting the forward support member to the rear support member. Again, in a preferred form, the second side support also includes a tension spring hinge rotatably connecting the forward support member to the rear support member.
From the foregoing it will be seen that this invention is well adapted to attain all of the ends and objectives hereinabove set forth, together with other advantages which are inherent to the apparatus. [0021]
It will be understood that certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations. This is contemplated by and is within the scope of the claims. [0022]
As many possible embodiments may be made of the invention without departing from the scope thereof, it is to be understood that all matter herein set forth or shown in the figures of the accompanying drawings is to be interpreted as illustrative and not in a limiting sense. [0023]
