DESCRIPTION
[0055] The present invention relates to the reduction of noise coming from and/or being delivered to an object. In particular, the invention relates to a noise reducing cover. Although the noise reducing cover is illustrated and described in the context of being useful for babies and/or for pets, the present invention can be useful in other instances. Accordingly, the present invention is not intended to be limited to the examples and embodiments described herein.
[0056]
[0057] The body 105 of the cover 10 includes a noise reducing portion 111 that makes up at least a portion of the body 105 and preferably a major portion of the body 105. The body 105 may also include one or more non-noise reducing portions 112, such as shown in
[0058] In one version, at least a portion of the noise reducing portion 111 is a noise reducing composite fabric 113. By noise reducing composite it is meant that noise reducing body comprises a combination of materials and/or a material that has been treated in a manner so as to create the noise reducing properties, as described above. By fabric, it is meant that the material behaves in a fabric-like and/or cloth-like manner in that it is thin, flexible, moldable, shapeable, and/or conformable as a sheet or a piece of fabric. The noise reducing composite fabric 112 may be formable into a variety of shapes and configurations, as will be described.
[0059] An example of a noise reducing composite fabric 113 is shown in
[0060] Within the interior space 140 noise reducing material 145 may be provided. By noise reducing material it is meant a material that reduces the transmission of sound therethrough when compared with a different material of the same size and shape. Noise reducing materials are typically of decreased permeability, of higher density or packing, and/or of increased thickness than conventional materials as will be explained in more detail. Noise reducing materials made from cotton or polyester fibers may be treated, dimensioned, and/or packed in a manner that the noise transmission is less than if the material was not treated, dimensioned, and/or packed. For example, the noise reducing material 145 may comprise one or more of treated or untreated cotton, polyester, or cotton/polyester blend, polyurethane, needle punched cotton batting, mineral wool, stone wool, glass wool, foam, fiberglass, cellulose insulation, recycled paper product, recycled denim, mass loaded vinyl or silicone, or the like. In one version, the noise reducing material 145 comprises foam, such as acrylic foam. Alternatively or additionally, the noise reducing material 145 comprises a polyester, such as a triple weave polyester that is made up of a top fabric layer, a bottom fabric layer, and a high density yarn layer between the two fabric layers. Alternatively or additionally, the noise reducing material 145 comprises one or more, and preferably a plurality, of layers of needle-punched cotton batting, which has a lower loft or airiness than untreated cotton. The noise reducing material 145 can be in a solid sheet 150 form, as shown in
[0061] The outer covering 115 can be made of any suitable material. In one version, the outer covering 115 is made of a material that is sufficiently strong to contain the noise reducing material 145 in the interior space 140. In one version, the outer covering 115 may also be made of material that allows the noise reducing cover 10 to be flexible and/or moldable. For example, the outer covering 115 may be made of one or more of polyester, cotton, polyester/cotton blend, laminate, a spray-on protective coating, Gore-Tex, acrylic foam, and the like, and in one particular version comprises polyester. In addition, in one version, at least the surface 110 of the outer covering 115 is made of a material that is safe and comfortable to come in contact what a baby's skin. In one version, the outer covering 115 is made of a water resistant or water repellant material. The first layer of material 120 and the second layer of material 125 may be made of the same or different material.
[0062] Another version of a noise reducing composite fabric 113 for a noise reducing cover 10 is shown in
[0063] The first layer 120 and/or second layer 125 to which the lining 160 is attached may be a fabric or other material. For example, the first layer 120 and/or second layer 125 may comprise a material that allows the noise reducing baby cover to be flexible and/or moldable. For example, the first layer 120 and/or second layer 125 may comprise one or more of polyester, cotton, polyester/cotton blend, laminate, a spray-on protective coating, Gore-Tex, and the like, and in one particular version comprises polyester. In addition, in one version, at least the surface 110 of the outer covering 115 or the outer surface 126 of the first layer 120 and/or the outer surface 127 second layer 125 is made of a material that is safe and comfortable to come in contact what a baby's skin. In one version, the outer covering 115 is made of a water resistant or water repellant material. The first layer of material 120 and the second layer of material 125 may be made of the same or different material. When used, the additional noise reducing material 175 can comprise any of the above mentioned noise reducing materials in either solid sheet form or as loose material. In one particular version, the additional noise reducing material 175 comprises triple weave polyester which includes high density yarn.
[0064] The noise reducing composite fabric 112 of
[0065] To achieve a desire level of noise reduction, the noise reducing composite fabric 113 can include a combination of the above three factors. For example, for a given permeability, the density and/or thickness can be adjusted so that the achieved noise level is at a desired level. In another example, for a given density, the permeability and/or thickness can be selected so that the noise reduction is at a desired level. In another example, for a given thickness, the permeability and/or density can be selected so that the noise reduction is at a desired level. This latter example can be important when the thickness of the noise reducing composite fabric 113 needs to be sufficiently thin to maintain the flexibility of the fabric. For example, in one version, the noise reducing composite fabric 113 is less than 0.2 inches thick, or less than 0.1 inches thick. In this version, the permeability and the density of the noise reducing composite fabric can be selected so that the noise reducing composite fabric is sufficient to reduce a 60 decibel noise in the human audible frequency range by at least about 12 decibels, or by at least about 15 decibels, or by at least about 18 decibels, or by about 20 decibels.
[0066] In one particular version, the noise reducing composite fabric 112 incorporates all three of the above-mentioned factors. In this particular version, the noise reducing composite fabric 113 includes an impermeability coating, such as an acrylic foam coating 160, that is applied to the inner surface 165 of the first layer 120 and/or the inner surface 170 of the second layer 125 of a fabric to make it impermeable. The foam coating 160 that is sprayed onto the inner surface 165 of the first layer 120 and/or the inner surface 170 of the second layer 125 of a fabric adds another benefit in that the resulting impermeable material remains flexible so that the cover can be adapted in shape into a desired form. The noise reducing composite fabric 113 can further include an additional noise reducing material 145 in the interior space 140. In one version, the additional noise reducing material 145 comprises a triple weave polyester/yarn fabric whereby higher density and tightly woven polyester and yarn add density. Thickness is created by having three layers of material that are stitched together. The combination of materials also serves to filter out different frequencies of sound.
[0067] One version of a noise reducing cover 10 include a noise reducing composite fabric 113 as shown in
[0068] Together the outer covering 115 and the noise reducing material 145 form the noise reducing composite fabric 113 that can be used to form a noise reducing cover 10 that serves as a barrier to noise. The noise reducing cover 10 when used as a noise reducing baby cover 100 can be positioned between a baby, such as a baby that is crying or that is likely to start crying, and another person so that the noise from the baby that reaches the person is a significant reduction in noise compared to the noise that would reach the person in the absence of the noise reduction baby cover 100. In addition, the noise reducing baby cover 100 can be positioned between a source of noise and a baby so that the noise from the source that reaches the baby is a significant reduction in noise compared to the noise that would reach the baby in the absence of the noise reduction baby cover 100.
[0069] In use the noise reducing cover 100 can be used to cover at least a portion of the baby in a manner that at least partially blocks the transmission of noise to and/or from the baby. In one version, the noise reducing baby cover 100 can be at least partially wrapped around the baby. Alternatively or additionally, the noise reducing baby cover 100 can be hung or otherwise held in a position where it establishes a wall or barrier that is spaced from the baby.
[0070] In one version, the outer covering 115 can be made of a material that also serves to block the transmission of light. By reducing the amount of light that penetrates the noise reducing cover 100, an environment can be created around that baby that is more soothing and womblike and that can help to calm the baby so the baby can sleep and/or cry less. In this version, the outer covering 115 can comprises one or more light reducing materials, such as one or more of velvet, polyester, cotton, high density black yarn, and the like. In one particular version, the outer covering 115 comprises polyester with a foam coated backing. In this version, the material and/or arrangement of the material is effective in reducing by at least 95% the light transmission, more preferably at least 99%, and most preferably at least 99.9%, as measured by a standard lux meter, such as an ennoLogic Light Meter eL200K. In one version, the noise-reducing material can be removed, and the cover can be made of the light-reducing material without the noise-reducing features. In another version, the outer covering comprises a triple weave polyester with the foam coating.
[0071] In one version, the outer covering 115 can be made of a material that also serves to provide heat block and temperature insulation properties. By reducing the amount of heat that can pass through the cover 10. This version is particularly useful when the cover 10 is used as a baby cover 100. The baby cover 100 prevents a baby beneath the baby cover from overheating, especially when in the sun. In this version, the material and/or arrangement of the material is effective in reducing heat transmission due to rays of sunlight by at least about 50%, more preferably at least about 60% over a cover that lacks the noise reducing portion 111.
[0072] A version of a noise reducing cover 10 in the form of a noise reducing baby cover 100 is shown in
[0073] In another version, the straps may be detachable. Additional optional features, such as a pocket 240 or the like, can also be provided on the outer covering 115.
[0074] Another version of a noise reducing cover 100 is shown in
[0075] Another version of a noise reducing cover 10 in the form of a noise reducing baby cover 100 is shown in
[0076]
[0077] Another version of the noise reducing cover 10 in the form of a noise reducing baby cover 100 is shown in
[0078] Another version of the noise reducing cover 10 in the form of a noise reducing baby cover 100 is shown in
[0079] In one particular version, as shown in
[0080] Various other feature or designs for the noise reducing cover 10 can additionally or alternatively be provided. For example, the noise reducing cover 10 can be made of a material that also blocks light and/or that provides heat insulation. The outer covering 115 can be quilted or not quilted and/or can included printed designs, images, or indicia. The noise reducing cover 10 can be in the form of a sling or can include an integrated sling under the apron version.
[0081]
[0082] Alternatively, as shown in
[0083] The noise reducing pet cover 700 can be selectively placed on, around, or near a pet to reduce the noise coming from the pet and/or being heard by the pet. For example, when used in proximity to a barking dog, the noise reducing cover with reduce the sound of the barking so that the barking is less annoying to those in proximity to the pet and/or can reduce the distance at which the barking sounds are detectable. In addition, the noise reducing pet cover 700 can reduce the noise that is presented to the pet. Thus, as easily agitated pet is less likely to hear sounds that can disturb the pet, and a sleeping pet is less likely to be awakened by a noise.
[0084] The noise reducing pet cover 700 can optionally be provided with additional features. For example, the noise reducing pet cover 700 can include a closure system whereby one or more panels 730 can be secured in a covering position. For example, a closure system cab comprise a strap extending from a panel 730. The strap can have a snap or the like that snaps onto another panel 730 or other portion of the noise reducing pet cover 700. In one version, a hook and loop fastener or a zipper can be attached the panel 730.
[0085] The noise reducing pet cover 700 can be constructed in accordance with any of the above embodiments disclosed in connection with the noise reducing baby cover 100. For example, one or more of the panels 730 can be made of a noise reducing composite fabric, such as one or more of an acrylic foam backed fabric, a triple weave high density yarn, and a mass loaded vinyl. In one version, one or more mass loaded vinyl inserts are positionable within a pocket within one or more of the panels 730 of the noise reducing pet cover 700. For example, a handle exposing feature can be provided that includes a flap that is positionable in an open position to expose a handle of the pet compartment. The flap can have a fastener system, such as a hook and loop fastening system, that secures the flap in one or more of an open and closed position. In another version, the flap can be in the form of a rollable piece of material. The exposing feature can be made of noise reducing material or may be absent noise reducing material. In one version, the noise reducing pet cover can be provided with an optional vent in one or more of the panels 730. For example, a panel 730 can have a side flap that makes up only a portion of a panel 730. The side flap can be selectively opened to allow air to enter the pet compartment 705 and/or to allow for interaction with a pet within the pet compartment 730. The side flap can also be equipped with a mechanism to maintain the side flap in one or more of the close and open positions.
