CORNER PROTECTOR CONSTRUCTION This invention relates to a construction utilized for protecting the corners of objects to prevent damage to the objects during shipping and handling. Such protectors are typically used in association with appliances and furniture and other objects which can only be successfully marketed when they present an undamaged appearance.
The use of corner protectors is wide spread, particularly with respect to objects which are subject to damage when they are dropped-or otherwise mishandled. The corners of such objects are naturally most susceptible to damage and, therefore, the protection afforded by packing cartons and the like has been supplemented by re-enforcing means utilized for protecting corners.
In addition to appliances and furniture, corner protectors are widely used in connection with bundles of sheet rock paneling and the like since the exposed corners of such bundles are quite susceptible to damage and since such damage can significantly diminish the value of the sheets. Taylor US. Pat. No. 3,443,684 issued on May 13, 1969 provides a disclosure of a corner protector which is particularly suitable for use in connection with such bundles. This application particularly describes means for efficiently applying steel bands which are utilized for securing the bundles.
There is a constant need to provide corner protectors which are capable of being produced at low cost and which can be efficiently used from the standpoint of initial assembly and from the standpoint of actual protection of the goods.
It is the general object of this invention to provide an improved corner protector which meets these needs to a degree heretofore unattained.
It is a more specific object of this invention to provide a corner protector design which can be efficiently manufactured, efficiently stored and-shipped, and very rapidly assembled whereby the use of the corner protectors leads to minimum difficulty.
It is a still further object of this invention to provide a corner protector design which exhibits completely adequate protecting capability while at the same time being characterized by automatic assembly means so that the protectors can be used in an efficient manner by unskilled personnel.
These and other objects of the invention will appear hereinafter and for purposes of illustration but not of limitation, specific embodiments of the invention are shown in the accompanying drawings in which:
FIG. 1 is a fragmentary perspective view illustrating a corner protector in association with a bundle;
FIG. 2 is a perspective view illustrating the bundle with the corner protectors in position;
FIG. 3 is a perspective view of the corner protector viewed from the inside;
FIG. 4 is a perspective .view of the corner protector viewed from the opposite side;
FIG. 5 is a perspective view of the corner protector in the partially unlocked condition;
FIG. 6 is a perspective view of the corner protector illustrated in the open position prior to locking;
FIG. 7 is an enlarged fragmentary cross-sectional view of the corner protector taken about the line 7-7 of FIG. 4;
FIG. 8 is a plan view of the corner protector;
FIG. 9 is a plan view of the corner protector looking from the opposite side; and,
FIG. 10 is a plan view of a blank section utilized for forming the corner protector.
This invention generally relates to a corner protector adapted to be formedfrom a blank of cardboard, preferably a corrugated sheet. The blank is die-cut to provide a suitable shape particularly with respect to automatic locking means which comprise a feature of the protector. A plurality of scorelines are formed in the blank to facilitate the folding operation. One'of the scorelines bisects the blank in one direction while the remaining scorelines are positioned perpendicular to the one scoreline. These remaining scorelines then permit folding of blank portions into overlying relationship whereby a multiple thickness arrangement is achieved. When the blank is folded so that a corner configuration is formed, locking tabs automatically come into play whereby the protector is immediately ready for use.
The corner protector 10 illustrated in the accompanying drawings comprises a three-walled structure consisting of a horizontal wall 12 and vertical walls 14 and 16. The vertical walls are perpendicular with each other, and the wall 12 is perpendicular to the vertical walls so that a corner configuration is achieved as best illustrated in FIGS. 3 and 4. v
The corner protector is adapted to be used in association with a bundle 18 or in association with someother type of object which defines exposed corners likely to be damaged if the object is mishandled. Thus, the corner protectors of the invention are used in a generally conventional manner in that the protectors are located on the bundle or other object 18 with a cover or carton 20 then being located around the bundle.
The specific configuration of the protector can be best understood by considering the blank 22 illustrated in FIG. 10. As indicated, this blank preferably comprises a section of a cardboard sheet and is preferably corrugated. The blank is substantially rectangular and is provided with a plurality of foldlines, these lines being formed by scoring of the blank.
The foldlines comprise a first line 24 located at approximately the center of the blank. Additional foldlines 26, 28 and 30 are defined on one side of the line 24, and a fifth foldline 32 is formed on the opposite side of the line 24. A sixth foldline 34 extends perpendicular to the other five foldlines, and this sixth line substantially bisects the blank.
A diecutting operation is preferably involved in the forming of the blank. This operation includes the provision of ears 36 and 38 formed, respectively, adjacent the foldlines30 and 32. These ears extend outwardly after the blank has been folded into the desired configuration. As explained in the aforementioned Taylor patent, these ears function to hold bands which are employed for securing a bundle of sheets or for other purposes. Thus, the blank design of the invention permits the inclusion of these cars while accomplishing the other benefits of the invention.
An enlarged diamond-shaped cut-out 40 having a stemshaped portion 42 is included in the blank. As will be explained, this arrangement enables folding of the blank into the final configuration desired for use. Similarly, an elongated cutout 44 is defined along this same foldline 34 whereby additional freedom of movement is provided during folding operation to enable achieving of the desired configuration.
The blank defines a pair of outer wing portions 46 positioned on opposite sides of the cutout 44. One wing portion 46 carries a tab 48 and defines an adjacent cutout slot 50. The other wing portion carries a tab 52 terminating in a small semi-circular cutout 54.
In accordance with a preferred form of the iinvention, the blank 22 comprises one corner of a large sheet which defines at least three other blanks. These blanks are preferably secured together along lines 56 which may be perforated so that the individual blanks 22 can be readily separated for use. By providing four or more blanks in a single sheet, storage and inventory problems can be greatly minimized. Furthermore, workmen can be given a single sheet which will provide corner protectors for one end of a bundle being prepared for binding and shipping.
In utilizing the blank shown in FIG. 10, the blank is first folded about the line 28 so that the blank section 58 is located in overlying relation with the blank section 60 on the opposite side of the line 28. Thereafter, the blank is folded about the lines 26 and 30 so that a triple thickness of material is developed for the walls 12 and 16 adjacent the juncture of these walls. It will be noted that the line 28 is a double-scored line to facilitate bending through 180. The lines 26 and 30 are single-scored which tends to automatically permit bending of these walls to a limit of 90. The wing portions 46 are thereafter folded to a 90 position such as shown in FIG. 6.
When the entire configuration is then folded through 90 about the line 34, the configuration of FIGS. 3 and 4 is achieved. At this point, the locking tabs come into play since the tab design is such that one of the tabs on the wing portions 46 will automatically be received relative to the other tab. The particular interlocking arrangement of these tabs is shown in FIGS. 3, 5, 8 and 9. It will be noted that the tabs define abutting edge portions 62 and 64, with these edge portions serving as latch means which complement each other to resist any accidental opening of the corner protector once it has been folded into positionfor use.
The particular locking tab design accomplishes automatic locking due to the fact that the wing portions 46 are adapted to slide relative to each other as the construction is folded. As these surfaces slide, the leading edge of one enters the slotted area defined by the other. Once the 90 movement of the wing portions is completed, the interlocking is accomplished. In this connection, the edges of the stem 42 located at the end of the cutout 40 provide abutments to limit the folding about line 44 to 90.
The corner protector construction of the invention is characterized by a relatively inexpensive design since the entire blank can be formed with high production die-cutting and scoring equipment. The fact that a plurality of the blanks can be held in a single sheet assemblyis also of importance from the standpoint of shipping and inventory expense.
The ears 36 and 38 will automatically be positioned as best shown in FIGS. 1 and 4 when the folding operation occurs. Specifically, the ears 38 are formed as extensions of the outer surface of the walls 14 and 16. The ears 36 automatically enter the openings which are provided when the sections 46 are folded to a 90 position relative to the ears 38. A double-thickness of the ears is, therefore, provided for enabling a strong binding positioning structure.
The corner protector design is also distinctly advantageous from the standpoint of the amount of protection achieved by the relatively uncomplicated design. Thus, a minimum of a treble thickness of material is provided for all three walls of the construction. Protection is, therefore, afforded from any direction.
It will be understood that various changes and modifications may be made in the above described construction which provide the characteristics of the invention without departing from the spirit thereof particularly as defined in the following claims.
