The present invention relates to a body conforming, reusable, washable, textile holder for removably holding at least one electronic device in close bodily contact. More particularly, the invention relates to a reusable wrap or tube holder constructed to enclose a portion of the body where the electronic device is to be held. The electronic device may be a cellular telephone, a wireless communication device, a personal audio device, a wearable computer, an electronic monitoring device, an electronic identification card, or other electronic device. The invention also relates to a system comprising the body conforming holder and an electronic device for use therewith, and a method for holding such an electronic device in close bodily contact by wearing the holder.
In an environment of rapid electronic innovation, personal electronic devices are becoming more numerous and much smaller. As a result, a good deal of attention is now being focused on technology-enabled clothing, wearable personal computers, and garments designed for holding electronic devices. Wearable computer systems have previously comprised bulky electronic components that are often held by heavy duty belts, vests, etc., such as described in U.S. Pat. No. 6,137,675. With continued development of miniature integrated circuits, wireless two-way links, flexible circuits, and the like, wearable computers are becoming more practical, and the corresponding holders can be designed to be much more convenient, comfortable, and discreet. Additionally, the recent proliferation of personal electronic devices, including cellular telephones, MP3s, PDAs, electronic identification cards, GPS devices, etc., has created a need for holders that provide a hands-free way to carry multiple electronic devices. Holders addressing this need typically are loose fitting jackets or vests with specially designed pockets, or bulky belts and wraps.
Thus, there is a continuing need for more convenient, comfortable, and discreet holders for securely holding electronic devices in close bodily contact where they are readily accessible.
The present invention relates to an electronic device holding system comprising a body conforming, reusable, washable, textile holder for removably holding at least one electronic device in close bodily contact, said holder being a wrap or tube constructed to enclose a portion of the body, and comprising an elastic region having a Holding Force (HF-4.0) of greater than about 0.1 kgf; and a Holding Force (HF-2.5) of less than about 1.0 kgf and at least one electronic device capable of being removably held in close bodily contact by said holder.
The invention also relates to an electronic device holding system comprising a body conforming, shirt-like, reusable, washable, textile holder for removably holding at least one electronic device in close bodily contact, said holder being constructed to enclose a portion of the body, and comprising an elastic region having a Holding Force (HF-4.0) of greater than about 0.1 kgf and a Holding Force (HF-2.5) of less than about 1.0 kgf; and at least one electronic device capable of being removably held in close bodily contact by said holder.
In another aspect, the invention relates to a an electronic device holding system comprising a body conforming, reusable, washable, textile holder for removably holding at least one electronic device in close bodily contact in a selected location, said holder comprising at least one pocket for receiving and supporting the electronic device, and said holder being a wrap or tube constructed to enclose a portion of the body, and comprising an elastic region having a Holding Force (HF-4.0) of greater than about 0.1 kgf and a Holding Force (HF-2.5) of less than about 1.0 kgf; and at least one electronic device capable of being removably held in close bodily contact by said holder.
The reusable, washable, textile holder of the invention is suitable for removably holding one or more coordinated electronic devices in close bodily contact in a desired position or location on the body of a user. In one embodiment, the body conforming holder removably holds one or more personal audio devices in close bodily contact against an area of the user's body for improved listening pleasure, holding convenience, and the like. The reusable holders and replaceable electronic devices herein are coordinated so as to have compatible shapes, sizes, and flexibility in order to fit reliably and comfortably against the body region of the wearer.
While not intending to be limited by theory, it is believed that the elastic properties of the textile holder provide sufficient holding force to hold the electronic device (e.g., a cellular telephone) in close bodily contact throughout a range of wearer motions. This sufficient, comfortable and reliable holding force often results in improved holding convenience and/or other performance benefits (e.g., better monitoring of body parameters, such as heart beat, blood pressure, etc.). Additionally, when the reusable holder and removable electronic device are designed and coordinated to work together, the resulting system can be optimized to provide consumer benefits such as improved wearing comfort, discreetness under clothing, and/or better stay-in-place performance.
The invention thus also relates to a system comprising a reusable, body conforming holder and at least one coordinated electronic device for use therewith, and a method for holding such an electronic device in close bodily contact in a region by wearing the holder. The electronic device has a size and shape compatible with the holder, and is capable of being held in close bodily contact in the desired body region by the holder. Typically, the electronic device and the holder are designed and coordinated to work together. As a result, the system may provide improved convenience, performance, wearing comfort, and/or discreetness. The electronic device and holder of this system may be packaged in a common, bundled, coordinated, or associated package or packages, and may be sold as a kit. The electronic devices may also be sold separately from the holder. Typically, replacement electronic devices would be sold separately from the holder, with or without instructions for use with the holder.
As used herein, the term “electronic device” refers to any suitable electronic device known by those skilled in the art, and combinations thereof, that may be held in close bodily contact by the holder. An electronic devise may be a cellular telephone, a wireless communication device, a personal audio system, an electronic identification card, an electronic watch, a Global Positioning System (GPS) device, an electronic heating device, a two-way wireless link system, an integrated circuit, and the like. An electronic device herein may also be a wearable personal computer system comprising one electronic component or a series of components and/or computer modules, connected by wires or wireless link systems. An electronic device may also be a body function monitor intended to monitor various body function parameters. In one embodiment, the electronic device is flexible so as to conform to body contours.
The term “reusable” refers to articles, such as the holders herein, intended to be reused. The articles may be cleaned, laundered or otherwise restored and/or reused after use.
The reusable holder/electronic device system of the present invention may comprise one or more devices mounted to the holder at the same time. However, for clarity, a holder/device system comprising a single electronic device is often described herein.
The holder of this invention is comfortable to wear notwithstanding the close conformity of the holder and electronic device to the wearer's body. It is believed that the sufficient and comfortable holding force provided by the holder is due at least in part to the force exerted by the elastic material used in the holder. The holder can be characterized as comprising an elastic region, and often more than one elastic region, with a moderate to low Holding Force (HF) value at a given extension distance, when measured as described herein, and a relatively high available stretch as worn. In contrast, previous holders have often attempted to hold an electronic device to a body area by using materials of relatively high stretch modulus that either hold the device using a tight overall fit or are designed to fit loosely. Such high modulus holders are often characterized as having high contractive forces, relatively low available stretch, and stretch properties in only one direction. Holders of these types generally have high Holding Force values at a given extension distance, and are often described as uncomfortable or unable to maintain the electronic device in close bodily contact, especially with body motion.
The elastic region of the holder herein cooperates with other regions so that the holder as worn provides a comfortable but sufficient holding force to hold the device against the body. Without being bound by theory, it is believed that the holding force provided by the holder is due at least in part to the compressive holding force provided by the stretch material in the holder. When the holder is stretched in use, the material exerts compressive forces to hold the electronic device closely against the wearer's body. This conformity is maintained over a wide range of body movement. The holding force is great enough to hold the electronic device in close bodily contact, but generally is not great enough to cause wearer discomfort. Material of the elastic region typically has moderate to low stretch modulus and provides relatively high available stretch as worn. This high available stretch, typically in both the lateral and longitudinal directions, combined with sufficient but relatively low holding force, helps to maintain the electronic device in close bodily contact across a range of body sizes, device sizes, and body motions. In one embodiment, the holder comprises an elastic region having a Holding Force (HF-4.0) of greater than about 0.05 kgf, typically greater than about 0.1 kgf, as measured by the Holding Force method presented herein. In another embodiment, the holder comprises an elastic region having a Holding Force (HF-4.0) of greater than about 0.2 kgf, typically greater than about 0.3 kgf. The elastic region typically also has a Holding Force (HF-1.0) of less than about 1.0 kgf. The elastic region typically has a Holding Force (HF-2.0) of less than about 1.0 kgf, and typically has a Holding Force (HF-3.0) of less than about 1.0 kgf. In one embodiment, the holder comprises an elastic region having a Holding Force (HF-4.0) of less than about 1.0 kgf, and typically having a Holding Force (HF-5.0) of less than about 1.0 kgf, more typically less than about 0.8 kgf. In another embodiment, the holder comprises an elastic region having a Holding Force (HF-5.5) of less than about 1.0 kgf, more typically less than about 0.8 kgf.
The elastic region of the holder can comprise any woven material, knit material, nonwoven material (with stretch incorporated as known in the art), or the like that possesses the requisite physical properties. Similarly, the holder can comprise one material or a combination of materials, stitching, and/or design patterns that collectively possess the requisite physical properties. The elastic region can be cut to an appropriate shape and size, and joined to the remaining portions of the holder. In one embodiment, the elastic region of the holder is wholly plain knit, typically jersey knit, from a combination of elastically extensible and non-elastically extensible yarns. The elastic properties of the individual yarns and the particular knitting pattern can be used to define the mechanical properties of the holder. The holder typically comprises knit material and elastomeric fiber material. In one embodiment, the holder comprises wholly plain knit, e.g., jersey knit, using elastomeric fiber material such as Lycra® or spandex yarn having suitable mechanical properties in all courses. Other knitting patterns and alternative yarns can be used to provide the desired mechanical properties. Suitable yarns include natural yarns, such as cotton yarns and wool yarns, and synthetic yarns, such as nylon yarns, polyester yarns, acrylic yarns, and combinations thereof, e.g., nylon yarns and cotton yarns. Typically, elastomeric fiber material such as Lycra® or spandex yarns are used with these natural and/or synthetic fibers to provide the desired stretch properties. In one embodiment, the elastic region of the holder comprises from about 5% to about 30%, typically from about 10% to about 25%, more typically from about 15% to about 20%, of the elastomeric fiber material, e.g., Lycra®. For example, the elastic region of the holder may comprise from about 80% to about 85% nylon yarn and from about 15% to about 20% of Lycra®.
While the device attachment region of the holder need not comprise an elastic material, it is typically extensible in both the longitudinal and lateral directions. Such elastic extensibility enables the holder to fit a variety of bodily shapes and sizes and provides good conformity to a wearer's body. The mounting region and electronic device attachment region cooperate with the elastic region of the holder to provide sufficient holding force to hold the device in close bodily contact throughout a range of wearer movements. Such a force helps maintain the device worn with the holder in close bodily contact. In one embodiment, the elastic region(s), mounting region(s), and the device attachment region(s) of the holder are made of the same material, typically a knit material as described above. The holder may comprise at least one additional extension, panel, or other structure extending beyond or attached to the above regions so long as it does not significantly interfere with the function of the holder.
While the present invention encompasses a wide variety of holder designs to fit various regions of the body with coordinated electronic devices, it will often be described in terms of a holder comprising a material of relatively high stretch and moderate to low stretch modulus, used in conjunction with an electronic device such as a cellular telephone, a wireless communication device, a personal audio device, a wearable computer, an electronic monitoring device, an electronic identification card, or other electronic device.
The holder 10 has a longitudinal centerline L and a lateral centerline T. The term “longitudinal” refers to a line, axis or direction in the plane of the holder that is generally elongated to accommodate fit around a body region. The term “lateral” refers to a line, axis or direction that lies within the plane of the holder that is generally perpendicular to the longitudinal direction. The elastic regions 12 are formed from a material of relatively high stretch and moderate to low stretch modulus. Such a wrap holder design could be worn around the waist region of a user to conveniently, comfortable, and effectively hold one or more electronic devices, such as components of a wearable computer, a personal audio system, or wireless communication device.
The holder 10 can comprise woven fabrics, knit fabrics, or special nonwoven fabrics (with stretch incorporated as known in the art), but typically comprises a knit fabric. Other materials having the requisite mechanical properties are also suitable. The holder is designed to be reusable, but typically is disposed of after a period of time (e.g., about 6 to 12 months depending on the amount of use) when it begins to lose elasticity or otherwise shows wear. When the holder is a knit fabric, the mechanical properties of the various components can be provided by a combination of the knit pattern used for a particular component and the yarns that are used. In one embodiment, the stretch properties of the elastic regions 12 of the holder are derived from knit materials known in the art. In one example, the elastic regions 12, mounting region 14, and device attachment region 16 are wholly knit. The holder typically comprises material having a basis weight similar to conventional undergarments in order to provide a desired “sheerness”. This relatively low basis weight and sheerness facilitates wearing this system comfortably and discreetly under outer garments.
The holder 10 is constructed to be reused and incorporates one or more areas, such as mounting region 14, to which a replaceable device herein can be removably mounted. The holder can be used with a wide variety of removable and replaceable electronic devices, including a cellular telephone, a wireless communication device, a personal audio device, a wearable computer, an electronic monitoring device, an electronic identification card, or other electronic device. In
Holder 10 comprises fastening means to enable it to be affixed to a desired location on the user's body in a manner that allows device 20 to overlie the desired body area. While various fastening means can be used,
Once electronic device 20 is mounted to holder 10 in the desired position, the device is placed in contact with the body. Holder 10 can then be wrapped around that portion of the body, with the end of the holder bearing fastener portion 26 being wrapped around the body portion as the final step. The system is secured to the body by bringing the surface of fastener portion 26 into contact with the exposed surface of fastener portion 28, enabling the hook and loop fastening members to engage. The system is thus securely affixed to the body of the user with electronic device 20 overlying the desired body area. As will be apparent to one of ordinary skill in this art, while the components depicted in
In one embodiment, electronic device 34 in
In another embodiment, electronic device 34 in
In another embodiment, electronic device 34 in
Holder 90 further comprises fastening system 98, which can comprise hook and loop fasteners, buttons, a zipper, etc., to close the holder around the user's torso. In one embodiment, holder 90 is a wrap and fastening system 98 comprises at least two cooperating fastening materials e.g., hook and loop fastening materials, affixed to opposed surfaces of the holder that can be positioned to removably enclose a portion of the body. Alternatively, the holder may be a tube, e.g., a pullover or T-shirt, which can be positioned to enclose a portion of the user's body, such as the torso. A fastening system 96, such as a hook and loop fastener or an alternate fastener, can be employed to retain electronic device 94 in pocket 92.
In another embodiment, the invention comprises a body conforming textile holder in the form of headgear, e.g., a hat or headband, and an electronic device capable of being removably held in close bodily contact by the holder.
It will be appreciated that holders herein may have other configurations besides those shown and described. For example, the holder may comprise one or more additional straps, panels, or cut-out areas. Other holder styles, designs, and configurations that comprise at least an elastic region and a device attachment region of suitable properties are within the scope of the invention. As described above, the holder may comprise at least one extension or panel so long as it does not significantly interfere with the holding function of the holder.
Test Method for Measuring the Holding Force (HF) of Materials Using A “Constant-Rate-of-Extension (CRE) Ball Force Test”
Overview: This method measures a force (HF) that is related to the holding force exerted by an extensible material when holding an article against a wearer's body.
Terminology: The Holding Force (HF) is the force exerted by a material when distending it with a force applied at right angles to the plane of the material, under the specified conditions. The angle of application of force and the area of the material upon which the force is applied varies continuously as the material stretches when tested as directed in this method. In the Constant-Rate-of-Extension (CRE) tensile testing machine, the rate of increase of the specimen length is uniform with time.
Summary of Test Method: Set up the tensile testing machine for performing this test in accordance with both the manufacture's instructions and procedures presented herein. A specimen of material is securely clamped without tension within a “Ball Burst Test” attachment. A force is exerted against the specimen by a polished, hardened steel ball attached to the tensile testing machine. Holding Force (HF) data are recorded as a function of extension distance.
Apparatus: Tensile testing machine, of the constant-rate-of-extension (CRE) type. Equipment includes an Imada DPZ High Performance Programmable Digital Force Gauge: Model DPZ-4, and an Imada Motorized Vertical Test Stand: Model MX-110-S Test Stand w/Digital Distance Meter, both available from Imada, Incorporated, Northbrook, Ill. The Force Ball Attachment (modified “Ball Burst Test” attachment) consists of a clamping mechanism to hold the specimen and a steel ball attached to the moveable force gauge of the tensile testing machine. The circular opening and ring clamp has an internal diameter of 5.1 cm (2.0 in). The polished steel ball connected to the force gauge has a diameter of 1.6 cm (0.62 in).
Sampling and Specimen Preparation: The specimen is taken from the elastic region of the holder. Clamp the specimen in the ring clamp of the apparatus. The specimen must be of sufficient diameter to be held securely within the 5.1 cm (2.0 in) diameter ring clamp. The specimen may not require cutting if there is ample room to securely clamp the specimen in the apparatus. Ensure the specimen is free of folds, creases, or wrinkles, and is without tension when clamped. If the specimen is not uniform (e.g., it has a pattern, stitching, or a seam, etc.), ensure that the area tested is representative of the elastic region.
Procedure:
In the above method:
All limits and ranges specified herein include all narrower ranges, limits, and amounts that are within the specified limits and ranges, and such narrower ranges and limits may be claimed even though those limits and ranges are not separately listed.
While particular embodiments of the present invention have been illustrated and described, various other changes and modifications can be made without departing from the spirit and scope of the invention. It is therefore intended to cover all such changes and modifications that are within the scope of this invention.
