Field of the Invention My invention relates to the field of art encompassing devices which are designed to be attached to a chair and the like having a trackway or guide upon which a flexible sheet is mountedfor movement. In particular, the invention pertains to a novel carpet saver apparatus attached to the underneath portion of a chair frame having a rug attached to a bracket of the apparatus which bracket is mounted for movement in a guide of the apparatus so that the rug is movable from a stored position to an in-use position.

2. Description of the Prior Art The conventional practice to prevent undue wear to a carpet is to use small rugs commonly called throw rugs to cover an area of the carpet to be protected. The major. disadvantage in the use of a throw rug is that it is difficult and inconvenient to store when it is notin use.

The present invention is simple in construction, easy to use and provides a storage space for a rug when it is not in use protecting the carpet in front of a chair or couch.

SUMMARY OF THE INVENTION The invention provides a carpet saver apparatus to be attached to the underneath portion of a chair or couch frame. The apparatus includes a rug attached to a receptacal for slidable movement from a stored position beneath the chair to an in use position in front of the chair so that the feet of a person sitting in the chair rest on the rug of the carpet saver. The receptacle is adjustably attached to an adjustable mounting means which is in turn mounted to the frame of the chair so that the carpet saver apparatus can be mounted to chairs and the like of various sizes and shapes.

FIG. 5 is a perspective view of the tray of the carpet saver;

FIG. 6 is an enlarged cross-sectional view of the slidable attachment means taken along line 66 of FIG. 5.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings, a preferred carpet saver apparatus, generally denoted as 10, is illustrated in FIG. 1 installed to a chair frame 12 beneath a chair 14.

With particular reference to FIGS. 3 and 4, the carpet saver apparatus includes adjustable mounting means 16 mounted to the chair frame 12, adjustable attachment means 18 connected to the adjustable mounting means 16, a receptacle 20 pivotally. connected to the adjustable attachment means 18, and a flexible material 22, such as a rug, slidably attached to the receptacle 20 by slidable attachment means 24. The rug 22 is illustrated in FIG. 1 in an in-use position beyond the front 15 of the chair 14 so that the feet of a person seated in the chair 14 will rest upon the rug 22.

' Now turning to FIG. 2, the broken lines show the position of the receptacle 20 when the rug 22 is in the inuse position, and the solid lines show the position of the receptacle 20 when the rug 22 is in the stored position. Further, the in-use position of the receptacle 20 is indicated at A andthe stored position is indicated at 6Bl9,

As can be best seen in FIG. 3, the adjustable mount ing means 16 is comprised of two spaced apart

parallel rods

26, 28 each attached at one end to the frame 12 at the front of the chair 14 and at its opposite end to the frame 12 at the back of the chair 14.

Further, each of the

rods

26, 28 are formed of a first rod segment 27 and a second rod segment 29. The first rod segment 27 is axially slidably received in the second rod segment 29 so that the length of each of the

rods

26, 28 may be made shorter or longer by sliding the

rod segments

27, 29 axially of each other to adjust the

rods

26, 28 to fit chairs of various sizes and shapes.

Referring to FIGS. 2, 3 and 4, the adjustable attachment means 18 includes two sets of two

arms

38, 40 and 39, 41. One set of

arms

38, 40 are connected to rod 26 and the other set of arms 39, 41 are connected to the rod 28. The

arms

38, 40 are each pivotally attached at one of their ends to rod 26 and the arms 39, 41 are each pivotally attached at one of their ends to rod 28. The pivotal attachment of one set of

arms

38, 40 can be seen in FIG. 4 which illustrates the

arms

38, 40 pivotally attached to the rod 26, the attachment of arms 39, 41 to the rod 28 being identical. Each of the

arms

38, 40 and arms 39, 41 also have an elongated slot disposed generally along their longitudinal axis. FIG. 5 shows the

slots

46, 48 in arms 38, 41, respectively, the slots in arms 39, 41 being identical.

Referring now to FIGS. 2, 3 and 5, the receptacle 20 is in essence a tray having a front edge 30, a back edge 32 and two

side edges

34, 36. The front edge 30 is located generally adjacent and generally parallel to the front of the chair 14. The tray 20 also has two elongated spaced

apart slots

50, 52 with their axes disposed generally perpendicular to the front edge 30 of the tray 20. The tray 20 is shown as arcuately shaped in longitudinal cross section as can be best seen in FIGS. 2 and 5. The arcuate shape concavely faces the carpet upon which the chair 14 rests. This arcuate shape is desirable in that is results in a clearance space between the front edge 30 of the tray 20 and the front end of the chair frame 12 (see FIG. 2) for the hand of a person when reaching beneath the chair 14 to pull the rug 22 from its stored position to its in-use position.

As can be best seen in FIGS. 3, 4 and 5, the tray 20 is connected to the set of

arms

38, 40 near its side edge 34 and to the set of arms 39, 41 near its edge 36. The connection means is preferably a pivot mounting generally denoted as 54, 56 having a generally horizontal axis of rotation disposed generally perpendicular to the

slots

50, 52 in the tray 20. In addition, the axis of rotation of the pivot mounting 54, 56 is disposed forward of the transverse enterline of the tray 20, i.e., toward the front edge 30 of the tray 20 to produce an unbalance in the tray 20 which, in effect, biases the tray to pivot about the pivot mounting in a direction to elevate the front edge 30 and displace the back edge 32 downwardly when the flexible material 22 is in the stored'position on the tray 20. The pivot mounting 54, 56 is illustrated as a shaft 58 and

journals

60, 62 attached to the tray 20, the shaft being rotatably mounted in the

journals

60, 62 so that the tray will pivot about the shaft. One end 64 of shaft 58 is slidably received in the

elongated slots

46, 48 in

arms

38, 40, respectively, and the other end '66 of shaft 58 is slidably received in the

elongated slots

46, 48 in arms 39, 41, respectively. The shaft 58 is selectively positioned in the slots and secured in that position by fasteners, such as wing nuts 68 and 71 threadably engaging

ends

64, 66 of shaft 58 and tightening against the

arms

38, 40 and 39, 41, respectively.

The function of the slots 49, 50 in the pivotally mounted arms 39, 41 and in the pivotally mounted

arms

38, 40 is to allow the tray 20 to be selectively positioned at various vertical distances relative to the chair frame 12. .To adjust this vertical distance, the wing nuts 68, 71 are loosened and the shaft 58 is moved vertically, the

ends

64, 68 sliding in the slots in the arms. 'As the shaft 58 is moved upwardly toward the chair frame l2,the arms of each set of arms pivot toward each other about their pivotally mounted ends 42, 44 and 43, 45 decreasing the angle included between each of the arms 42, 44 and rod 26 and between each of the arms 43, 45 and rod 28. When the desired distance is reached, the

wing nuts

68 and 70 are tightened to secure the rod 28 in place. As the shaft 58 is moved downwardly away from the chair frame 12, the arms of each set pivot away from each other about their pivotally mounted ends 42, 44, and 43, 45 increasing the angle included between each of the arms 42, 44 and the rod 26, and between each of the arms 43, 45 and the rod 28. f

The rug 22 is slidablyattached to the tray 20 by slidable attachment means 24 so that it can be slid from a stored position on the tray 20 to an in-u se position in front of thechair and visa versa. This slidable attachment means 24 is best illustrated in FIGS. 4, 5 and 6 and includes an elongated bracket 70 disposed with its longitudinal axis generally perpendicular to the longitudinal axes of the

slots

50, 52 in the tray 20. The elongated bracket 70 includes downwardly extending

projections

72, 74 which are slidably received in the

slots

50, 52 of tray 20, thus, the bracket 70 is movably secured to the tray for movement in the longitudinal direction of the tray 20 toward and away from the front edge 30 thereof. Further, the attachment means 24 includes means to removably connect the rug 22 to the bracket 70. This removable connection is illustrated in FIG. 6 as a groove 75 defined in the elongated bracket 70 which clampingly engages a tongue 73 attached to the rug 22.

The rug 22 is illustrated in FIG. 1 as being generally T-shaped. The means defining the tongue 73 being purpose for the T-shaped rug 20 is to provide protection to the carpet upon which he chair 14 rests substantially across the entire width of the chair, but allowing the rug 22 to fit on the tray beneath the chair 14 by folding the

arms

78, 80 of the rug over the stem 76 of the rug. A rectangular rug would not provide the same area of protection as the T-shaped rug 20. The adjustable mounting means 16 allows the carpet saver apparatus to be mounted to frames of chairs and the like of various front to back dimensions, while the adjustableattachment means 18 allows the carpet saver apparatus to be adjusted for various chairs and the like having different heights or vertical dimensions from the floor to the chair frame. These features provide for universal use of the carpet saver device.

When the rug 22 is in the stored position, as shown at B in FIG. 2, the rug 22 lays completely on the tray 20. In this position the tray 20 is pivoted about the pivot mounting 54, 56 due to the unbalanced condition resulting from the position of the pivot mounting, so that the front end of the tray is elevated toward the chair frame. The carpet saver apparatus is therefore not readily visible from the front of the chair.

To move the rug 22 from its stored position to its inuse position, the user of the apparatus reaches beneath the chair and grasps the rug 22 pulling it forward. As

I the rug is pulled from its stored position on the tray to its inuse position in front of the chair, the tray 20 pivots about the pivot mounting 54, 56 in a direction indicated by the arrows in FIG. 2. When the rug has been slid from the tray to its position in front of thechair, the

arms

78, 80 of the rug are unfolded from their folded position over the stem 76 of the rug so that the rug now covers the carpet for essentially the entire widthof the chair. The position A in FIG. 2 shows the orientation of the tray when the rug is in the in-use position, and

. FIG. 1 clearly shows the relationship of the arms 78 and attached to the rug near the base of the stem 76 of the juncture of the

arms

78, 80 and the stem 76, or the arms 78, may be separate components from the stem 76 being affixed thereto by strips of fabric. The

80 of therug, arm 78 being illustrated in its unfolded position and arm 80 being illustrated in the process of being unfolded from its stored position over the. stern 76 of the rug.
