Abstract

Disclosed are various embodiments for retaining a sheet on a mattress. A membrane comprising a plurality of extensions disposed along the perimeter of the membrane is displaced underneath a mattress. The extensions of the membrane are composed of an elastic material and the membrane is composed of a material that generates sufficient friction when in contact with the mattress to be displaced. The extensions are configured to retract to an original length, wherein the original length of each extension corresponds to a size of the mattress. Additionally, the extensions are disposed at a distance apart from each other so as to substantially retain a sheet applied on the mattress.

DETAILED DESCRIPTION

(6) Disclosed are features for a membrane disposed underneath a mattress for retaining a sheet on the mattress. The membrane includes extensions comprised of a material capable of expanding and retracting to various lengths in order to retain the sheet. These extensions protrude along the perimeter of the membrane and may be disposed at varying distances between each other. For example, in some instances, the extensions may be disposed close to each other to enhance retention capabilities of the membrane. In other instances, the extensions may be disposed farther apart from each other and still maintain retention capabilities of the membrane.

(7) A clip is affixed at the end of each extension. The clip can be applied to a portion of the sheet to be retained on the mattress. The clip has two halvesa first half affixed to the extension of the membrane and a second half tethered to the first half. In some embodiments, the second half may not be connected to the extension. To retain the sheet, a portion of the sheet is inserted between the two halves which are then fastened together to secure the sheet within the clip. The halves may be fastened together, for example, by a button or the like. In some embodiments, the clip is comprised of a material capable of gentle treatment of the sheet to be retained. For example, the clip may be composed of a rubbery material that gently secures the sheet within the clip when the two halves are fastened together.

(8) In operation, the clips affixed to the extensions and the membrane firmly retain the sheet on top of the mattress. The membrane disposed underneath the mattress is securely positioned by friction generated between the membrane and the mattress when in contact. Once the sheet has been inserted between the two halves of the clips and the clip fastened together, the extensions of the membrane operate to retain the sheet at a desired tension. For example, the extensions are designed to stretch and retract to compensate for unintended and/or unwanted shifting of the sheet. In some instances, the stretching and retracting may be automatic in response to the unintended and/or unwanted shifting.

(9) FIG. 1 illustrates an underside of a mattress 100 depicting a membrane 103 and extensions 106a-106j protruding from the perimeter of the membrane 103. The membrane 103 is smaller in size than the mattress 100 and may be circular in shape. In other embodiments, the membrane may be of a different shape such as a square, rectangle, triangle, or other shape sufficient to have a perimeter from which extensions 106 can protrude. Additionally, the extensions 106 have a thickness such that they can retain the sheet without tearing.

(10) Extensions 106 may be disposed at varying distances apart from each other along the perimeter. The extensions 106 are disposed apart from each other at a sufficient distance such that the sheet can be retained by the membrane 103 at a desired tension. In some embodiments, the distance apart may be uniform between all extensions 106. In other embodiments, distances between each of the respective extensions 106 may differ. In still other embodiments, distances between extensions 106 disposed along the top and bottom sides of the membrane 103 may be the same and distances between extensions 106 disposed along the left and right sides of the membrane 103 may be the same. Additionally, in other embodiments, the distance between extensions 106 along the corners of the membrane 103 may differ with the distance between extensions 106 disposed along the sides of the membrane 103.

(11) FIG. 2 illustrates a clip 200 to firmly retain a sheet on the mattress 100. In one embodiment, the clip 200 includes two halves, a first half 203a and a second half 203b, that fasten together to firmly retain the sheet. For example, the sheet may be received in at an area between the first half 203a and the second half 203b. The first half 203a and the second half 203b may be tethered together via a tether 206. In one embodiment the first half 203a is fixed to the body of the clip 200 and the second half 203b is tethered to the first half 203a by the tether 206.

(12) The first half 203a and the second half 203b are fastened together via a fastener 209. The first half 203a of the clip 200 may include a male end 213 of the fastener 209 and the second half 203b of the clip 200 may include the female end 216 of the fastener 209. To retain the sheet, the sheet may be received between the first half 203a and the second half 203b and fastened together by the fastener 209, i.e. joining the male end 213 with the female end 216. The sheet is thusly retained by the clip 200.

(13) The fastener 209 is designed to retain the sheet without causing any tears or perforations in the sheet. Preferably, the fasteners 209 does not cause any damage to the sheet when fastened together. To this end, the fastener 209 may be a snap or other type of fastener that does not diminish the integrity of the sheet. In one embodiment, the fastener 209 may be magnets that function to fasten the first half 203a of the clip 200 and the second half 203b of the clip 200 together using magnetics. For instance, the first half 203a may include a positive end of a magnet and the second half 203b may include a negative end of a magnet that join together when brought in close proximity.

(14) FIG. 3 illustrates a clip 200 retaining a sheet 300 between the first half 203a of the clip 200 and the second half 203b of the clip. In one embodiment, the clip 200 only retains a portion of the sheet 300. As can be appreciated, the sheet 300 may have a surface area larger than that of the mattress 100. The portion of the sheet 300 retained by the clip 200 corresponds to the size of the fastener 209 of the clip 200.

(15) FIG. 4 illustrates a clip 200 affixed to an extension 106 of the membrane 103. In one embodiment, the clip 200 includes a latching mechanism 400 to affix the clip 200 to the extension 106. For example, the latching mechanism 400 may be a belt-buckle, or the like, configured to receive the extension 106 and secure the clip 200 to the extension 106. In one embodiment, an insertion 403 of the extension 106 is inserted into the latching mechanism 400, where the insertion 403 may be of various lengths. For example, a larger length for the insertion 403 may cause the clip 200 to apply a larger amount of tension on the sheet 300 when retained. Similarly, a smaller length for the insertion 403 may cause a smaller amount of tension on the sheet 300 when retained. Thus, varying the length of the insertion 403 may cause a variation in the tension of the sheet 300 when retained by the clips 200.

(16) FIG. 5 illustrates the membrane 103 retaining the sheet 300 on a mattress 100 using clips 200 that are affixed to the extensions 106 of the membrane 103. The sheet 300 may be fitted or rectangular and are retained at a desired tension by adjusting the length of the extension 106 inserted into the latching mechanism 400 of the clip 200.
