Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates generally to chair coverings. More particularly, the invention relates to a portable chair cover cloth for standard children&#39;s chairs. 
       BACKGROUND OF THE INVENTION 
       [0002]    In today&#39;s classrooms for children, seating is provided to assist with the pedagogy of children. Seats used in these classrooms are often of a miniature size to allow smaller children to make use of chairs. These chairs are often of small size and standard shape. Often these chairs are stackable, however, sometimes chairs are equipped or attached to a hard planar desktop so as to form a one-piece desk. 
         [0003]    Chairs in common use include a metal frame or base attached to a plastic seat. The base includes four legs attached to a mount. Sometimes, these legs come in a pair of upside down quasi-U-shaped legs that are mounted on a base. A hard plastic seat is permanently attached to the base. The seat will often have a somewhat flat (or other ergonomically shaped) horizontal bottom, and a back. Oftentimes these chair include a single molded plastic seat that includes both seat and back, however it is known in the art to provide such seats with ergonomic apertures and/or provide a separated seat and back portion that are bound through a base back. 
         [0004]    Generally, the chairs are a convenient method of seating children, as the chairs are generally light weight and resilient. However, drawbacks for these chairs include the lack of comfort (especially prominent in active children who do not feel comfortable sitting for long periods of time any way). The hard plastic chairs can also provide pain in children when long periods of sitting can cause vasoconstriction in portions of the body that are pressed against the seat surface. 
         [0005]    Further, as the chairs are generally interchangeable, many children often use the same chair through out the day. This, along with the unsanitary nature of many immature children, can cause the chairs to act as microbial growth stations that can lead to spread of bacteria and disease. 
         [0006]    A chair cover is intended for student chairs to help solve several problems. Common and reoccurring comments from students include incorrect posture leading to muscle fatigue and bone misalignment, uncomfortable contact with a chair surface, and general discomfort with standard sized chairs. Furthermore, some children sense an unfair disadvantage to students or others who seem more comfortable in cushioned chairs. The comment list goes on and on. Unfortunately, the comments students make are true. They are often uncomfortable all day! 
         [0007]    First and foremost, the chair cover may alleviate student discomfort to allow better focus on classroom instruction. A chair cover provides a sanitary solution. Cushion is easily removed so cover can be washed and used multiple times. 
         [0008]    A cozy seat cover can be rolled up and secured to easily fit into any backpack or carried using the shoulder strap. This makes it easy for students to transport a chair cover from class to class, or from home to school. 
         [0009]    Students are able to choose from a variety of printed fabrics that match their personality and personalize their own space. 
         [0010]    Therefore, there exists a need to provide a comfortable solution or complement to the standard hard body chairs. Furthermore, there exists a need for a hygienic solution to classroom and other seating arrangements. Others have attempted to provide solutions with elaborate or disposable chair covers. 
       OBJECTS OF THE INVENTION 
       [0011]    It is therefore an object of the present invention to provide a chair cover that will ease the comfort of a seated person. 
         [0012]    It is another object of the present invention to provide a chair cover that is easily transported and applied to a chair. 
         [0013]    It is yet another object of the present invention to provide a hygienic chair cover solution to protect a user from potential pathogens on seating apparatuses. 
         [0014]    It is still another object of the present invention to provide a method for covering a chair so as to provide support, comfort, hygiene and/or fashion to the user. 
         [0015]    It is still yet another object of the present invention to provide a portable chair cover that can be easily applied to a first chair, transported, and applied to the same and/or other chair. 
         [0016]    It is an additional object of the present invention to provide a comfortable seated experience. 
         [0017]    These and other objects of the present invention will become more apparent to those skilled in the art as the description of the present invention proceeds. 
       SUMMARY OF THE INVENTION 
       [0018]    According to one aspect of the present invention, a method of covering a chair, the chair having a hard solid back and a hard solid seat, the hard solid back having an upper portion and a lower portion, the hard solid seat having a posterior portion and an anterior portion with the lower portion of the hard solid back being proximate to the posterior portion of the hard solid seat, the hard solid back having a length in the direction from the upper portion to the lower portion and a width, the hard solid seat having a length in the direction from the upper posterior portion to the anterior portion and a width which is approximately the same as the width of the hard solid back. One can produce a cloth cover with an inner layer and an outer layer and a space between the inner layer and outer layer, the cloth covering having a reclosable opening, the cloth cover has a length that is approximately the same length as the combined length of the hard solid back and the hard solid seat, and the cloth cover has a width that is approximately the same as the width of the hard solid seat and back. The cloth cover has one or more extension pieces of cloth connected to the cloth cover to extend around and cover part of the hard solid back of the chair at the upper portion of the back and to extend around and cover part of the hard solid seat of the chair at the anterior portion of the seat. A foam pad, approximately the same length as the length of the cloth cover, and approximately the same width as the width of the cloth cover, fits inside the cloth cover. A foam pad is inserted into the cloth cover through the reclosable opening. The cloth cover is placed onto a chair by extending the one or more extension pieces of cloth around the upper portion of the hard solid back of the chair and around the anterior portion of the hard solid seat of the chair. A tether may be attached to the cloth cover at one or more distinct points along the cloth cover. The tether may be attached at along line intersecting the mid point of the cloth cover. The cover may be rolled up for storage, whereby the tether is set around the cover forming a portable case. The cover may then be unrolled for re-use. To maintain and/or wash the cover, the pad may be removed from the layers. The cover may be applied to a chair with an elastic band and may be secured to the chair with a friction material on one layer. 
         [0019]    The present invention also includes an apparatus chair cover for use with a standard chair. A first layer is set for engaging a seated user, which may be a single fabricated sewn layer including darts cut out of corners, and a second layer is disposed opposite and generally co-planer with said first layer. The first and second layers are bound together along a first circumferential edge. A padding layer is disposed between said first and said second layers. An elasticized binder is disposed along the second circumferential edge. An opening along the second layer allows for removal of the padding layer. A retaining strap is formed in a loop, whereby the loop is coupled to the second layer at at least one point. The second circumferential edge may extend over a portion of the second layer, thus exposing the first layer around a working edge. A mounting strap may be used to secure an applied chair cover to the chair. The aforementioned opening may be a pocket wherein the first layer extends around the first circumferential edge to fold over the padded layer. The retaining strap may be is elasticized. The elasticized binder may be an elastic substance sewn directly onto the first layer. If necessary, at least one of the layers can be made out of an anti-microbial fabric.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0030]    Referring to  FIGS. 1 and 2 , cover  1  is positioned upon chair  6 . Chair  6  is preferably a standard plastic molded single piece chair with metal base  8  supported by legs  7 . Base  8  is generally bolted or riveted onto chair  6  with bolts  9 . Chair  6  may include ergonomic and/or ventilation slits  10  for maximum comfort, portability, lower manufacturing costs, and other benefits known in the art. Although a preferred embodiment is sized and positioned for a small child&#39;s molded chair, it is envisioned that chair cover  1  can be modified and prepared for most chairs that include at least a seat such that the rim of the seat provides anchoring for chair cover  1 . Preferably chair cover is made of multiple panels of fabric, preferably cotton or canvas. It is also preferred that paneling includes a design or coloring to help personalize and distinguish various chair covers. 
         [0031]    Front panel  2  of chair cover  1  is exposed as an alternative seating surface for the chair user. Ridge  3  of chair cover  1  provides enough material to extend over edges or contours of chair  6  so as to secure cover  1  to chair  6 . Chair cover  1  may include a mid-section  12 , wherein an alternative embodiment, for particular chair size or when there is a significant angle between the chair back and seat, mid-section  12  may include a softer bendable line, or a break of cushion material coinciding with an inserted cushion, or any other reasonable attribute that assists chair cover placement or comfort. 
         [0032]    Chair cover  1  has back ring  4  which may be placed over edges or contours of chair  6  and thereby help secure chair cover  1  to chair  6 . It is contemplated that ring  4  includes an elasticized band  5 . Band  5  may be separate rubber band encapsulated within the material of chair cover  1 , or as in the preferred embodiment, an elasticized ring sewn directly into the material of the cover  1 , preferably into front panel  2 . By sewing band  5  directly into the material, there is less likelihood that band  5  will shift or be damaged. Ring  4  is preferably part of the same sheet as front panel  2 , folded over to create ring  4  and space for band  5 . 
         [0033]    Referring to  FIG. 3 , back features of the chair cover  1  are not normally apparent to a user preparing to sit, or one seated on the chair. Ridge  3  forms the circumference of chair cover  1 , and has a general form so as to fit properly over a select chair. Back ring  4  includes band  5  as described above. Ring  4  is set within crumple zone  15 . Crumple zone  15  is preferably an area where excess material of chair cover  1  is allowed to overlap and/or pleat in a preferably random manner, whereby overlaps are kept to a minimum. Crumple zone  15  allows for expansion of back ring  4  and band  5  to allow chair cover  1  ridge  3  to be properly applied over chair contours. Crumple zone  15  also simplifies manufacture of cover  1  panels (front  2  shown in  FIG. 1 , and back  14 ) so as to allow a single fabric sheet to serve as template for a panel. Back panel  14  is preferably a rectangular piece sewn onto the underside of front panel  2 . Back panel  14  may include gripper  13 . Gripper  13  is a bar, or portion of material, that has a friction coefficient greater than that of the material forming back panel  14 . Gripper  13  further secures chair cover  1  to the chair surface. Back panel  14  also includes loop  20 . Loop  20 , or tether, functions to allow for ease of storage and portability of chair cover  1  when not in use. When applied to a chair, loop  20  should be thin enough so as not to discomfort a seated user. Loop includes loop ring  21 , preferably made of threaded elastic material. Loop ring  21  forms an elastic belt that can rotate, flip and stretch to allow for entire circumference of a folded chair cover  1  to be fit within loop ring  21 . Loop  20  is mated with back panel  14  of chair cover  1  at connection point  22 . Connection point  22  can be a single stitch, or shaped stitched area (reference numeral  24  in  FIG. 7 ), preferably a square of dimensions just less that width of loop ring  21  at rest. Preferably, when loop ring  21  is stretched, loop ring width decreases to a width less than that of dimension of connection area  22 . 
         [0034]    Referring to  FIG. 4 , chair cover  1  is seen in compacted form. Front panel  2  is mainly obscured and protected when chair cover  1  is rolled up as shown. Back panel  14  provides much of the outer surface that is exposed when in this compacted form. Thus, front panel  2  may be protected and kept clean for the user during transport or storage. Ridge  3  also serves to form edges that further protect user engaging portions of front panel  2 . Band  5  is set along the exterior perimeter to form a somewhat soft shell. Loop may be set around chair cover  1  with loop ring  21  properly holding chair cover  1  in this position. 
         [0035]    Referring to  FIGS. 5-9 , Front panel  4  underside mates with back panel  14 , in the absence of any padding layer. It is preferred that back panel  14  is stitched to front panel  2  on three of four sides, leaving one of the short ends open. This opening between front and back panel forms pouch  50 . Pad  30  may be inserted into pouch  50 . Back panel  14  may include pocket  40 , which is created by doubling under the material of back panel  14  at the opening for pouch  50 . Thus a catch, or pocket  40 , holds pad  30  in pouch  50 , preventing pad from slipping out of pouch  50 . Pad  30  is preferably formed to fill the dimensions of back panel  14 . Padding is preferably malleable enough to fit into pouch  50  and then be maneuvered under pocket  40  to be held in double-back  41  of pocket  40 . 
         [0036]    Front panel  2  having rounded edges, is folded under itself to house sown in elastic band  5 . Elastic band  5  may be separate band enclosed in wrap over portion of front panel  2 , or the elastic band may be sewn into the fabric of front panel  2 . Back panel  14  may form a pouch of preferably rectangular shape, set at under side of front panel  2 . Back panel  14  is preferably attached at three sides, leaving, preferably one of the short ends, e.g. top or bottom open. It is preferred that the back panel  14  is folded under at double-back  41  so that the edge of back panel  2 , those near the opening of pouch  50 , include doubled-over portion  41 . This doubled over portion  41  acts as a catch to prevent pad  30  from removing from pouch  50 . 
         [0037]    Note,  FIG. 7  shows an alternative embodiment whereby band  5  is a separate entity from front panel  2  and is not sewn directly into the fabric. 
         [0038]      FIG. 8  demonstrates front panel  2 . Band  5  may be sewn along perimeter of fabric. Cut outs  51 , at each corner, may be used to allow for the front panel  2  to assume a proper shape to stretch around and hug a chair contour.  FIG. 9  demonstrates back panel  14 , which is preferably smaller than front panel  2 . Optionally, back panel may be sewn onto front panel  2  along all four edges. In this case, zipper  32  allow access to pouch  50 . Chair cover may include security straps  33 , or a loop, to secure chair cover  1  to a chair. Further, chair cover  1  may include a seat belt  34 , or loop or fasteners, to secure a seated user to chair cover  1 .
