REMOVABLE LAMP SHADE COVER
BACKGROUND OF THE INVENTION
1. Field of the Invention This invention relates generally to home furnishing accessories, and in particular to a removable cover for a lamp shade diffuser.
BACKGROUND OF THE INVENTION
1. Field of the Invention This invention relates generally to home furnishing accessories, and in particular to a removable cover for a lamp shade diffuser.
2. Description of the Prior Art Lamp shades are typically constructed of relatively stiff but lightweight materials and usually can be installed and removed from a lamp base with minimum effort.
After an extended period of use, the shade may become outdated or discoloured so that replacement is desirable. An exact lamp shade replacement, in some cases, may not be possible. On other occasions, it may be desirable to coordinate the appearance of the lamp shade with other room furnishings such as curtains, bed linen, pillows and the like.
The range of conventional lamp shade pattern and colours which are available for such fashion coordination is limited, and is generally expensive.
It is known to provide a fabric covering as a solution to the problem of lamp shade replacement. Such coverings have heretofore been serviceable in most respects but have not provided an economical, re-usable, pleated alternative to lamp shade replacement.
Moreover, because of variations in the lamp shade diameter and taper, it has been necessary to customize each such covering according to the specific dimensions of each individual lamp shade.
OBJECTS OF THE INVENTION
It is, therefore, the principal object of the present invention to provide a conformable, removable lamp shade cover, which is adjustable to accommodate various lamp shade sizes.
A related object of the invention is to provide a conformable, removable lamp shade cover having a pleated appearance.
Yet another object of the invention is to provide an improved lamp shade cover that can be prepared from a rectangular swatch of cloth.
SUMMARY OF THE INVENTION
A covering for a lamp shade diffuser is prepared from a rectangular swatch of cloth. The tap and bottom edges of the swatch are hemmed to provide casing pockets, which run along the length of the swatch.
An elastic band is cut into two predetermined lengths, depending on the diameter of the top and bottom of the lamp shade. The shorter of the two elastics is received in the upper casing pocket and the longer elastic is received in the lower casing pocket.
The cloth portions forming the hems and the upper and lower casing pockets are gathered and stitched at each end of the elastic band so that the length of elastic band exceeds the stitched length of the gathered hem. The ends of the rectangular swatch of cloth are sewn together to produce a tubular covering. The elasticized top hem is positioned around and over the top edge of the lamp shade, thereby defining an overlap. The elasticized bottom hem is expanded while the tubular cover is being pulled down and over the lamp shade.
The bottom hem is pulled under the bottom edge of the lamp shade, thereby defining an underlap. The overlap and underlap can then be adjusted to provide an equal distance around the top and bottom diameters of the lamp shade.
The novel features, which characterize the invention, shall be defined by the claims. The forgoing and other objects, advantages and features of the invention will hereinafter appear, and for purposes of illustration of the invention, but not of limitation, an exemplary embodiment of the invention is shown in the appended drawings.
FIG. 1 is a perspective view of a lamp having a lamp shade decorated with a removable lamp shade covering constructed according to the teachings of the present invention.
FIG. 2 is a view of a length of elastic band cut into two predetermined lengths.
FIG. 3 is a top view of a rectangular swatch of cloth which illustrates the pattern for constructing the lamp shade cover shown in FIG. 1.
FIG. 4 is a rectangular cut-out taken from the swatch shown in FIG. 3 which has been partly assembled into a removable lamp shade cover.
FIG. 5 is a perspective view of a removable lamp shade cover, which is ready to be installed on a lamp shade.
FIG. 6 is a sectional view of the inside seam assembly of the lamp shade cover as illustrated in FIG. 5.
DETAILED DESCRIPTION OF THE PREFERED EMBODIMENT
In the description that follows, like parts are marked throughout the specifications and drawings with the same reference numerals, respectively. The drawings are not necessarily to scale and in some instances proportions have been exaggerated in order to more clearly depict certain features of the invention.
Referring now to FIGS. 1 and 5, a removable lamp shade cover 14 is shown assembled onto a lamp shade 11, which is affixed onto a convention lamp base 12. The lamp shade cover 14 includes an underlap 16, an overlap 18 and an intermediate sidewall portion 1.
According to an important feature of the invention, the underlap 16 is hemmed along a stitch line 21 adjacent the lower edge 3 thereby defining a casing pocket 22.
The overlap 18 is stitched along a stitch line 4 adjacent the upper edge 2, thereby defining a casing pocket 5. Although a single fold hem is illustrated, a double-fold can be used to good advantage.
The adjustable feature of the invention is provided by a length of elastic band 6, cut into two predetermined lengths 7, the shorter elastic 8, which is received within the upper casing pocket 5, and a longer elastic 9, which is received within the lower casing pocket 22, as illustrated in FIGS. 2, 4 and 6.
According to an important feature of the invention as illustrated in FIGS. 1, 5 and 6, the hemmed portion 4, forming the upper casing pocket 5, and the hemmed portion 21, forming the lower casing pocket 22; are gathered so that the length of elastic bands exceed the length of the gathered hems and are stitched with a cross stitch 10, to the casing pocket it is received through. According to this arrangement, the top hem 4 and bottom hem 21 are elasticized to provide a snug fit around the upper and lower edge of the lamp shade 1 l, and also to produce pleats 15 along the length of the covering.
After the casing pockets 5 and 22 have been gathered and the elastic secured with a cross stitch 10 at each end, A and B of the lamp shade cover 14 are sewn together to form a stitched seam 17, and thereby producing a tubular enclosure or covering as illustrated in FIG. 5.
After the stitched seam 17 has been sewn, the material forming the upper casing pocket 5 and lower casing pocket 22, in which the elastic bands 8 and 9 are received, is folded back to the same casing pocket and sewn on each side as indicated by the stitched dashed lines 19 on either side of the stitched seam 17. According to this arrangement, the elastic bands 8 and 9 can expand freely within the casing pockets, while extensions of the gathered material in the hems 4 and 21 is limited, thereby preserving the pleated appearance 15. Although a single fold is illustrated, a double-fold can be used to good advantage.
The lamp shade cover 14 is preferably cut in rectangular form, from a large swatch of cloth 13, as illustrated in FIG. 3. However, if desired, a lamp shade cover can be prepared from a swatch of cloth having curved sides as indicated by the dashed pattern 20. It will be appreciated, however, that the curved pattern does not make efficient use of the available material 13, whereas the rectangular pattern 1 does.
After an extended period of use, the shade may become outdated or discoloured so that replacement is desirable. An exact lamp shade replacement, in some cases, may not be possible. On other occasions, it may be desirable to coordinate the appearance of the lamp shade with other room furnishings such as curtains, bed linen, pillows and the like.
The range of conventional lamp shade pattern and colours which are available for such fashion coordination is limited, and is generally expensive.
It is known to provide a fabric covering as a solution to the problem of lamp shade replacement. Such coverings have heretofore been serviceable in most respects but have not provided an economical, re-usable, pleated alternative to lamp shade replacement.
Moreover, because of variations in the lamp shade diameter and taper, it has been necessary to customize each such covering according to the specific dimensions of each individual lamp shade.

DETAILED DESCRIPTION OF THE PREFERED EMBODIMENT
In the description that follows, like parts are marked throughout the specifications and drawings with the same reference numerals, respectively. The drawings are not necessarily to scale and in some instances proportions have been exaggerated in order to more clearly depict certain features of the invention.
Referring now to FIGS. 1 and 5, a removable lamp shade cover 14 is shown assembled onto a lamp shade 11, which is affixed onto a convention lamp base 12. The lamp shade cover 14 includes an underlap 16, an overlap 18 and an intermediate sidewall portion 1.
According to an important feature of the invention, the underlap 16 is hemmed along a stitch line 21 adjacent the lower edge 3 thereby defining a casing pocket 22.
The overlap 18 is stitched along a stitch line 4 adjacent the upper edge 2, thereby defining a casing pocket 5. Although a single fold hem is illustrated, a double-fold can be used to good advantage.
The adjustable feature of the invention is provided by a length of elastic band 6, cut into two predetermined lengths 7, the shorter elastic 8, which is received within the upper casing pocket 5, and a longer elastic 9, which is received within the lower casing pocket 22, as illustrated in FIGS. 2, 4 and 6.
According to an important feature of the invention as illustrated in FIGS. 1, 5 and 6, the hemmed portion 4, forming the upper casing pocket 5, and the hemmed portion 21, forming the lower casing pocket 22; are gathered so that the length of elastic bands exceed the length of the gathered hems and are stitched with a cross stitch 10, to the casing pocket it is received through. According to this arrangement, the top hem 4 and bottom hem 21 are elasticized to provide a snug fit around the upper and lower edge of the lamp shade 1 l, and also to produce pleats 15 along the length of the covering.
After the casing pockets 5 and 22 have been gathered and the elastic secured with a cross stitch 10 at each end, A and B of the lamp shade cover 14 are sewn together to form a stitched seam 17, and thereby producing a tubular enclosure or covering as illustrated in FIG. 5.
After the stitched seam 17 has been sewn, the material forming the upper casing pocket 5 and lower casing pocket 22, in which the elastic bands 8 and 9 are received, is folded back to the same casing pocket and sewn on each side as indicated by the stitched dashed lines 19 on either side of the stitched seam 17. According to this arrangement, the elastic bands 8 and 9 can expand freely within the casing pockets, while extensions of the gathered material in the hems 4 and 21 is limited, thereby preserving the pleated appearance 15. Although a single fold is illustrated, a double-fold can be used to good advantage.
The lamp shade cover 14 is preferably cut in rectangular form, from a large swatch of cloth 13, as illustrated in FIG. 3. However, if desired, a lamp shade cover can be prepared from a swatch of cloth having curved sides as indicated by the dashed pattern 20. It will be appreciated, however, that the curved pattern does not make efficient use of the available material 13, whereas the rectangular pattern 1 does.
3 Referring again to FIGS.1 and 5, after the lamp shade 11 has been placed on a flat surface, the upper edge 2 of the lamp shade cover 14 is placed over the top edge of the lamp shade 11, thereby forming an overlap 18. The elasticized lower edge 3 of the cover 14 is pulled down over the sides of the shade until the elasticized edge snaps under the entire bottom diameter of the shade, thereby forming an underlapl6. The overlap 18 of the cover is adjusted until it assumes a slightly smaller diameter than the top of the lamp shade. The underlapl6 is adjusted until it assumes an equal radius distance around the bottom diameter of the shade. The diameter of the lower edge 3 is adjusted by drawing the excess height of the cover to the bottom in order to maintain the desired overlap 18 along the top of the lamp shade, using care to preserve the desired underlap 16 of the cover. The pleating 15, can be adjusted, if necessary, by adjusting the overlap and the underlap to equally distribute the cloth around the top and bottom of the shade.
At this point, the lamp shade 11 with the cover 14 installed, is ready to be placed onto the lamp base 12. Final pleating adjustments are made by simply rotating the fabric around the top and bottom diameters, and adjusting the elasticized hems accordingly.
It will be appreciated that the lamp shade cover 14 can be easily removed for cleaning and re-installed by expanding the elasticized lower edge 3 and placing it over the shade from top to bottom, and snapping it under the bottom edge of the lamp shade l l, then adjusting the overlap and underlap accordingly.
Although preferred embodiments of the invention have been described in detail, it should be understood that various changes, alterations and substitutions could be made therein without departing from the spirit and scope of the invention as defined by the claims.
