CORNER COVERING DEVICE
BACRGROUND OF THE lN V ~'N'l'lON
1. FIELD OF lNV~N~ ON .
This invention relates to a 7corner covering device, more particularly to a corner covering device which is to be provided on the corners of a box so that an object, such as a television set or a similar fragile object, that was packed in the box can be moved to a desired destination without damage.
8UMMARY OF THE lNV~NllON
A main object of the present invention is to provide an improved corner covering member made by folding a T-shaped paper card which has two rectangular projections that extend from a pair of arm sections of the paper card on both sides of a center line. When folded, the rectangular projections form extra layers at the corner defined by the three walls of the corner covering member of the present invention.
Accordingly, t-he corner covering member of the present invention is similar to the above-described conventional corner covering member except that each of the L-shaped members has a rectangular projection which projects from the arm section and which extends in a direction similar to the transverse section. One of the second fold portions of the corner covering member extends through the rectangular projection so as to divi-de the latter into two symmetric portions. The - 2~77~1B
rectangular projection includes a fourth fold formed thereon and which is transverse to the center line, a first pair of opposed sides transverse to the center line, and a second pair of opposed sides parallel to S the center line and extending between the first opposed sides. The first pair of opposed sides has a predetermined length. Each of the transverse sections includes a free edge which is parallel to the arm section and which is provided with a notch. The notch has a periphery with a first side which is opposite to and parallel to the center line, and a second side which extends from the first side to the center line.
The first side has a length which is at least four times the thickness of the paper card. The second side has a lensth which is greater than half of the predetermined length of the first pair of opposed sides.

DET~TT.T~n DESCRIPTION OF THE PREFERRED EMBODIMENT
Z5 Figure 1 shows a conventional corner covering member which is to be provided on the corners of a box so-that an object, such as a television set or a ~~4~~ 2077416 similar fragile object, that was packed in the box can be moved to a desired destination without damage. The conventional corner covering member has a predetermined shape and is made from one-piece paper card (1), as shown in Figure 2. The conventional covering member includes three walls (X, Y, Z), each of which has two adjacent joining sides. Each of the joining sides of each of the walls (X, Y, Zj is connected to one of the two joining sides of the other two of the walls (X, Y, Z). The three walls (X, Y, 2) are perpendicular to one another so as to define a corner (V) therebetween.
When packing a fragile object in a box, the corner covering members are disposed at the corners of the fragile object before placing the latter in the box.
When the conventional covering member is unfolded, the foldable paper card (1) is shown to be substantially T-shaped and has a center line (C) which divides the foldable paper card (1) into two L-shaped members. Each of the L-shaped members includes an arm section (3, 4) which is perpendicular to the center line (C), a transverse section (5, 6) which is parallel to the center line (C) and an intermediate section (7) disposed adjacent to said center line (C) and interconnecting said arm and transverse sections [(3, 4), (5, 6)]. The paper card (13 further includes a first fold portion (2) between the intermediate sections (3, 4) and disposed on the center line (C), an __5__ 2077416 elongated slit (4) between the transverse sections (5, 6) and disposed on the center line (C), two spaced and parallel second fold portion [(41, 43) (31, 33)], one of said second fold portions (43, 31) being disposed between said intermediate section (7) and said arm section (3, 4), the other one of said second fold portions (41, 33) being disposed on said arm section (3, 4), and two spaced and parallel third fold portions - [(52, 53), (62, 63)] one of which is formed between said intermediate section (7) and said transverse section (5, 6), the other one of said third fold portions (53, 63) being disposed on said transverse section (5, 6). The second fold portions [(41, 43), (31, 33)] are parallel to the center line (C). The third fold portions [(52, 53), (62, 63)] are transverse to the center line (C).
A main drawback of the conventional corner covering member is that although the wall (Z) comprises four layers, the corner (V) defined by the walls (X, Y, Z) has only two layers of paper card. Therefore, in the event that a heavy object accidentally falls to the ground during shipment, the corner (V) of the corner covering member can not sufficiently protect the heavy object due to the limited thickness thereat.
Referring to Figures 3 and 4, a corner covering member of the present invention is made from folding a substantially T-shaped paper card (T) and includes a - --6-- 2077~16 first wall (L), a second wall (M) and a third wall (N) which are perpendicular to one another so as to define a corner (R) therebetween.
When the corner covering member is unfolded, the paper card (T) is substantially T-shaped and has a center line (C) which divides the same into two L-shaped members. Each of the L-shaped members includes an arm section (10, 30) which is transverse to the center line (C), a transverse section (50, 60) which is parallel to the center line (C) and an intermediate section (14, 34) which is adjacent to the center line (C) and which interconnects the arm and transverse sections [(10, 30), (50, 60)].
The paper card (T) further has a first fold portion (20) between the intermediate sections (14, 34) and disposed on the center line (C), an elongated slit (40) between the transverse sections (50, 60) and disposed on the center line (C), at least two spaced and parallel second fold portions [(13, 11), (31, 33)], one of which is disposed between the intermediate section (14, 34) and the arm section (10, 30) while the remaining one of which is disposed on the arm section (10, 30), and at least two spaced and parallel third fold pcrtions [(51, 53), (61, 63)], one of which is disposed be~ween the intermediate section (14, 34) and the transverse section (50, 60) while the remaining one of which is disposed on the transverse sections (50, 60). The second fold portions [(11, 13), (31, 33)] are parallel to the center line (C). The third fold portions [(51, 53), (61, 63)] are transverse to the center line (C). In the preferred embodiment, the second and third fold portions divide each of the arm and transverse sections [910, 30), (50, 60)] into two equally-sized regions which are similar in size to the intermediate section (14, 34).
The arm section (10, 30) has a longitudinal edge (L) from which a rectangular projection (12, 32) projects and extends in a direction similar to the transverse section (50, 60). One of the second folds (13, 33) extends through the rectangular projection (12, 32) and divides the same into two symmetric portions. The rectangular projection (12, 32) has a fourth fold (121, 321) formed thereon and transverse to the second fold portion (13, 33), a first side (Q) formed on the longitudinal edge (L) of the arm section (10, 30), a second side opposite to the first side, and third and fourth sides (P) which extend between the first and second sides tQ). The first side (Q) has a length of 30 cm while the third side (P) has a length of 20 cm.
Each of the transverse sections (50, 60) has a free 2S edge parallel to the longitudinal edge (L) of the arm section (10, 30). The free edge is provided with a notch (52, 62) which has a periphery with a fifth side --8-- 2077~16 (a) parallel to and opposite to the center line (C) and a sixth side (b) which extends from the fifth side (a) to the center line (C). The fifth and sixth sides have lengths of 4 cm and 20 cm respectively. Referring to Figure 5, the arm section (10, 30) is folded relative the second fold portion (13, 33) so as to form the arm sections (10, 30) into two overlaid portions. The folded arm sections (10, 30) is folded 180 degree relative to the second fold portion (11, 31), as shown in Figure 6. The rectangular projections (12, 32) are then bent 90 degree relative to the fourth folding line (121, 321) so as to position the bent portion of the rectangular projections (12, 32) vertically with respect to the arm section (10, 30), as illustrated in Figure 7.
The transverse section (50) is bent 180 degree relative to the third fold portion (53), as shown in Figure 8. Under this condition, the notch (52) is sufficient to permit the bent portion of the rectangular projections (12, 32) to be within the space confined by the fifth and sixth sides (a, b) of the notch (52).
The transverse section (50) is then folded along the longitudinal edge of the arm section (10) while the other L-shaped member is folded along the center line (C). The bent portion of the rectangular projection (30) is manually operated so as to provide the bent 9 2077~16 portions of the rectangular projections (12, 32) to be within a corner formed due to the continuous bending of the arm and transverse sections, as shown in Figure 10.
At this condition, a clearance is formed along the third fold portion (61j between one of the f~lded transverse sections (50) and one of the folded arm sections (30) as illustrated in Figure 11 At this time, the transverse sections (60) has a protruded portion formed due to the notch (62), which protruded portion can be inserted into the above-described clearance when the remaining transverse section (60) is folded relative to the third fold portion (63).
The corner covering member thus made does not easily unfold since the folded portions obtained from folding the arm section (10, 3GJ and the transverse section (50, 60) are prevented from disengaging from one another.
An important thing to note is that during application, the corner (R), together with the wall (N), should be placed under the object to be lifted so that the weight of in the object is concentrated on the wall (N), which wall (N) includes more layers when compared to the other two walls (L, M). The extra layers of paper card at the corner (R) of the present invention can cushion the object more efficiently.
The corner covering member of the present invention can be reused, thus permitting savings in the packing --lO-- 2077~ 1~
costs. In addition, since the corner covering member is made from folding a T-shaped paper card, a plurality of cards can be piled on top of one another, thereby permitting the storage of more paper cards in a relatively small storage space.
Referring to Figure 12, another preferred embodiment of a foldable paper card of the present invention is thinner than the first preferred embodiment. Each of the arm sections (10, 30) and the transverse sections l50, 60) includes four portions such that when the paper card is folded one of the walls comprises more layers than the remaining two walls due to the provision of rectangular projections.
The features and objects are the same as in the first preferred embodiment.
With the invention thus explained, it is obvious to those skilled in the art that various modifications and variations can be made without departing from the scope and spirit of the present invention. It is therefore intended that this invention be limited only as in the appended claims.

DET~TT.T~n DESCRIPTION OF THE PREFERRED EMBODIMENT
Z5 Figure 1 shows a conventional corner covering member which is to be provided on the corners of a box so-that an object, such as a television set or a ~~4~~ 2077416 similar fragile object, that was packed in the box can be moved to a desired destination without damage. The conventional corner covering member has a predetermined shape and is made from one-piece paper card (1), as shown in Figure 2. The conventional covering member includes three walls (X, Y, Z), each of which has two adjacent joining sides. Each of the joining sides of each of the walls (X, Y, Zj is connected to one of the two joining sides of the other two of the walls (X, Y, Z). The three walls (X, Y, 2) are perpendicular to one another so as to define a corner (V) therebetween.
When packing a fragile object in a box, the corner covering members are disposed at the corners of the fragile object before placing the latter in the box.
When the conventional covering member is unfolded, the foldable paper card (1) is shown to be substantially T-shaped and has a center line (C) which divides the foldable paper card (1) into two L-shaped members. Each of the L-shaped members includes an arm section (3, 4) which is perpendicular to the center line (C), a transverse section (5, 6) which is parallel to the center line (C) and an intermediate section (7) disposed adjacent to said center line (C) and interconnecting said arm and transverse sections [(3, 4), (5, 6)]. The paper card (13 further includes a first fold portion (2) between the intermediate sections (3, 4) and disposed on the center line (C), an __5__ 2077416 elongated slit (4) between the transverse sections (5, 6) and disposed on the center line (C), two spaced and parallel second fold portion [(41, 43) (31, 33)], one of said second fold portions (43, 31) being disposed between said intermediate section (7) and said arm section (3, 4), the other one of said second fold portions (41, 33) being disposed on said arm section (3, 4), and two spaced and parallel third fold portions - [(52, 53), (62, 63)] one of which is formed between said intermediate section (7) and said transverse section (5, 6), the other one of said third fold portions (53, 63) being disposed on said transverse section (5, 6). The second fold portions [(41, 43), (31, 33)] are parallel to the center line (C). The third fold portions [(52, 53), (62, 63)] are transverse to the center line (C).
A main drawback of the conventional corner covering member is that although the wall (Z) comprises four layers, the corner (V) defined by the walls (X, Y, Z) has only two layers of paper card. Therefore, in the event that a heavy object accidentally falls to the ground during shipment, the corner (V) of the corner covering member can not sufficiently protect the heavy object due to the limited thickness thereat.
Referring to Figures 3 and 4, a corner covering member of the present invention is made from folding a substantially T-shaped paper card (T) and includes a - --6-- 2077~16 first wall (L), a second wall (M) and a third wall (N) which are perpendicular to one another so as to define a corner (R) therebetween.
When the corner covering member is unfolded, the paper card (T) is substantially T-shaped and has a center line (C) which divides the same into two L-shaped members. Each of the L-shaped members includes an arm section (10, 30) which is transverse to the center line (C), a transverse section (50, 60) which is parallel to the center line (C) and an intermediate section (14, 34) which is adjacent to the center line (C) and which interconnects the arm and transverse sections [(10, 30), (50, 60)].
The paper card (T) further has a first fold portion (20) between the intermediate sections (14, 34) and disposed on the center line (C), an elongated slit (40) between the transverse sections (50, 60) and disposed on the center line (C), at least two spaced and parallel second fold portions [(13, 11), (31, 33)], one of which is disposed between the intermediate section (14, 34) and the arm section (10, 30) while the remaining one of which is disposed on the arm section (10, 30), and at least two spaced and parallel third fold pcrtions [(51, 53), (61, 63)], one of which is disposed be~ween the intermediate section (14, 34) and the transverse section (50, 60) while the remaining one of which is disposed on the transverse sections (50, 60). The second fold portions [(11, 13), (31, 33)] are parallel to the center line (C). The third fold portions [(51, 53), (61, 63)] are transverse to the center line (C). In the preferred embodiment, the second and third fold portions divide each of the arm and transverse sections [910, 30), (50, 60)] into two equally-sized regions which are similar in size to the intermediate section (14, 34).
The arm section (10, 30) has a longitudinal edge (L) from which a rectangular projection (12, 32) projects and extends in a direction similar to the transverse section (50, 60). One of the second folds (13, 33) extends through the rectangular projection (12, 32) and divides the same into two symmetric portions. The rectangular projection (12, 32) has a fourth fold (121, 321) formed thereon and transverse to the second fold portion (13, 33), a first side (Q) formed on the longitudinal edge (L) of the arm section (10, 30), a second side opposite to the first side, and third and fourth sides (P) which extend between the first and second sides tQ). The first side (Q) has a length of 30 cm while the third side (P) has a length of 20 cm.
Each of the transverse sections (50, 60) has a free 2S edge parallel to the longitudinal edge (L) of the arm section (10, 30). The free edge is provided with a notch (52, 62) which has a periphery with a fifth side --8-- 2077~16 (a) parallel to and opposite to the center line (C) and a sixth side (b) which extends from the fifth side (a) to the center line (C). The fifth and sixth sides have lengths of 4 cm and 20 cm respectively. Referring to Figure 5, the arm section (10, 30) is folded relative the second fold portion (13, 33) so as to form the arm sections (10, 30) into two overlaid portions. The folded arm sections (10, 30) is folded 180 degree relative to the second fold portion (11, 31), as shown in Figure 6. The rectangular projections (12, 32) are then bent 90 degree relative to the fourth folding line (121, 321) so as to position the bent portion of the rectangular projections (12, 32) vertically with respect to the arm section (10, 30), as illustrated in Figure 7.
The transverse section (50) is bent 180 degree relative to the third fold portion (53), as shown in Figure 8. Under this condition, the notch (52) is sufficient to permit the bent portion of the rectangular projections (12, 32) to be within the space confined by the fifth and sixth sides (a, b) of the notch (52).
The transverse section (50) is then folded along the longitudinal edge of the arm section (10) while the other L-shaped member is folded along the center line (C). The bent portion of the rectangular projection (30) is manually operated so as to provide the bent 9 2077~16 portions of the rectangular projections (12, 32) to be within a corner formed due to the continuous bending of the arm and transverse sections, as shown in Figure 10.
At this condition, a clearance is formed along the third fold portion (61j between one of the f~lded transverse sections (50) and one of the folded arm sections (30) as illustrated in Figure 11 At this time, the transverse sections (60) has a protruded portion formed due to the notch (62), which protruded portion can be inserted into the above-described clearance when the remaining transverse section (60) is folded relative to the third fold portion (63).
The corner covering member thus made does not easily unfold since the folded portions obtained from folding the arm section (10, 3GJ and the transverse section (50, 60) are prevented from disengaging from one another.
An important thing to note is that during application, the corner (R), together with the wall (N), should be placed under the object to be lifted so that the weight of in the object is concentrated on the wall (N), which wall (N) includes more layers when compared to the other two walls (L, M). The extra layers of paper card at the corner (R) of the present invention can cushion the object more efficiently.
The corner covering member of the present invention can be reused, thus permitting savings in the packing --lO-- 2077~ 1~
costs. In addition, since the corner covering member is made from folding a T-shaped paper card, a plurality of cards can be piled on top of one another, thereby permitting the storage of more paper cards in a relatively small storage space.
Referring to Figure 12, another preferred embodiment of a foldable paper card of the present invention is thinner than the first preferred embodiment. Each of the arm sections (10, 30) and the transverse sections l50, 60) includes four portions such that when the paper card is folded one of the walls comprises more layers than the remaining two walls due to the provision of rectangular projections.
The features and objects are the same as in the first preferred embodiment.
With the invention thus explained, it is obvious to those skilled in the art that various modifications and variations can be made without departing from the scope and spirit of the present invention. It is therefore intended that this invention be limited only as in the appended claims.
