Torso Device

Abstract

The torso device comprises a body having a central opening between integral front and rear members for positioning a user's torso. The front member has an upper surface (table surface), and the front and rear members have surface areas for contacting the user's torso. The front and rear members are configured to apply a compressive force to the user's torso. The surface areas and compressive force of the front and rear members hold the front member in a desired position relative to the user when the user is positioned in the central opening, for example, perpendicular to the user's torso when the user moves from a seated to a standing position and / or when the user is walking, or parallel to the floor surface on which the user is standing, thereby facilitating the availability of a table surface convenient for a given task or activity.

Description

[Technical field]

[0001] (Priority) This application claims the benefit of priority to U.S. Patent Application No. 17 / 169,385, filed on February 5, 2021, of the same title, the entire contents of which are incorporated herein by reference.

[0002] (Copyright) A portion of the disclosure herein contains material that is subject to copyright protection. The copyright owner has no objection to the facsimile reproduction by any person of the patent document or patent disclosure as filed or issued in the Patent and Trademark Office, but otherwise reserves all copyright rights whatsoever.

[0003] (Technical field) The device disclosed herein relates to a tabletop or horizontal surface for use by a human user, and more specifically, the device is worn by the user and includes a tabletop or horizontal surface structure to provide a tabletop surface that facilitates a given activity while the user is seated, standing, or walking. [Background technology]

[0004] The use of tables or horizontal supports or elements is known in the art and may be provided in the form of stand-alone articles that are usable by positioning the table so that a human user can use it. Typically, the table or horizontal support is configured so that a user can sit nearby, such as in a chair, and use the top surface of the table to perform a given activity or task. Standing tables are also known which are configured as stand-alone articles of height so that a user can stand nearby and use the top surface of the table to perform a given activity or task.

[0005] Such known tables and horizontal support members or elements do not meet the needs of today's mobile world, for example, to have a table, horizontal support element, or horizontal surface available when the user is moving, for example, walking or moving from one place to another, or when the user is standing. Conventional tables, whether sitting or standing, that require the user to move close to or be located close to the table are no longer convenient to use. It is desirable for the table to move with the user and to conveniently use the table surface or horizontal surface, even when the user is moving, standing still, or standing still. Summary of the Invention [Problem to be solved by the invention]

[0006] Therefore, there is a need for the development of a device that meets the increasing needs of today's users, whereby a table surface or horizontal support surface is always located in a convenient location for the user to perform a given task or activity, even when the user is moving or not positioned at a specific location such as a table position. [Means for solving the problem]

[0007] The torso device disclosed herein comprises a body having a central opening between a front member and a rear member. The front member and the rear member are of one unitary, unitary construction along an open end of the front member. The front member has a closed end. The front member has a rear edge and the rear member has a front edge opposite the rear edge of the front member. The rear edge of the front member and the front edge of the rear member each have a surface area configured to contact an adjacent portion of a user's torso when the user's torso is positioned in the central opening. When the device is in a relaxed state, i.e., when the user's torso is not positioned in the central opening, the closed end of the front member is biased inwardly towards the rear member and contacts the rear member even when the front member is not adjacent to the rear member.

[0008] The central opening is configured to accommodate placement of a human torso, and moving the closed end away from the rear member from the relaxed state to the activated state creates an open passageway for movement of the user's torso into the central opening. With the user's torso positioned inside the central opening, the surface areas of the front and rear members contact adjacent portions of the user's torso and exert a compressive force on the user's torso. The combination of the contact of the surface areas and the compressive force maintains the torso device in a desired position relative to the user's torso as the user moves from a sitting to a standing position and / or is standing and / or walking. The desired position is when the front member extends substantially perpendicular to the human torso or substantially parallel to a floor surface on which the user is standing, without being supported by the user's hands and / or other elements or members.

[0009] In one example, the desired position is maintained by a combination of contact of the surface area and the compressive force as the user moves from a sitting to a standing position and as the user walks.

[0010] In one example, the compression force is greater than or equal to about 0.2 ft·lb (foot-force pound=about 0.27 N·m), preferably greater than or equal to about 0.4 ft·lb (=about 0.54 N·m).

[0011] In one example, a desired position of the torso device relative to the user is achieved without using the user's arms or hands, and without the use of other fixation elements or means.

[0012] In one example, the rear member includes an extension element extending upwardly from the rear member a predetermined distance, the extension element configured to provide additional surface area contact with a back portion of a user's torso inside the central opening and to provide increased vertical stiffness to the torso arrangement to inhibit downward movement of the front member relative to the user's torso inside the central opening.

[0013] In one example, the extension element has a height from the lower surface of the rear member to the upper surface of the extension element that is at least 1.5 times the thickness from the upper surface of the front member to the lower surface of the front member.

[0014] In one example, the thickness of the front member may vary from the leading edge to the trailing edge.

[0015] In one example, the front member has a lip element that projects upwardly from an upper surface of the front member a predetermined distance and adjacent one or both of the leading and trailing edges.

[0016] In one example, the front and rear members are constructed from a first and a second elastic material, respectively, and the first elastic material has a greater density than the second elastic material.

[0017] In one example, the front member comprises primarily a first elastic material and secondary a second elastic material.

[0018] In one example, the first elastic material extends upwardly from a lower surface of the front member across most of the thickness of the front member between the lower surface and the upper surface.

[0019] In one example, the rear member comprises a first elastic material and a second elastic material in the same configuration as the front member.

[0020] This Summary is provided to introduce a selection of concepts that are further described in the Detailed Description. This Summary is not intended to identify key or essential features of the present disclosure, nor is it intended to be used to limit the scope of the present disclosure.

[0022] The torso device of the present disclosure will be described with reference to the accompanying drawings, in which like elements are designated with like reference numerals.

[0023] The torso device of the present disclosure generally comprises a body having a front member, a rear member, a first side element extending laterally from one side of the rear member toward the front member and separate from the front member, and a second side element extending laterally from the other side of the rear member and integral with the front member, i.e., the front member and the rear member are of a unitary structure integral with each other via the second side element.

[0024] With such an arrangement, a central opening is formed between the front and rear members, the central opening being sized to fit around the torso or waist of a human user, thereby providing a desired compressive or compressive force on the torso to maintain the torso device in its horizontal position, e.g., parallel to a floor surface and / or perpendicular to the torso of the user, when the torso device is worn.

[0025] The torso device may include a fastening or adjustment strap connecting the first side element and an adjacent portion of the front member, allowing the user to fit the torso device more snugly around their torso or waist.

[0026] The front member has a rear edge having a thickness sufficient to provide a surface area for contacting the front and sides of the user's torso, thereby preventing the front member from moving downwardly when worn by the user.

[0027] The rear member has an extension element that extends upwardly from the rear member a predetermined distance and provides a predetermined additional surface area for contacting the back of the user's torso, thereby maintaining the upper surface of the front member in a desired horizontal position and preventing inadvertent downward movement of the torso device when worn by the user.

[0028] In one example, the front member is sized to have a predetermined upper surface readily accessible in front of the user while the user is sitting, walking or standing, thereby enabling the user to perform a predetermined task or activity that is made possible by the presence of a horizontal surface, such as working with a laptop or tablet, playing games, fishing, writing, sewing, eating, reading, etc., without having to reposition themselves, e.g., by standing and then walking, to a separate table top or other separate horizontal surface.

[0029] FIG. 1 shows a torso device 10 according to an example of the present disclosure. The torso device 10 includes a main body 11, which includes a front member 12. The front member 12 has a front edge 14 that is arranged vertically and extends laterally along the front side of the front member 12. In one example, the front edge 14 has a curved surface that extends laterally or horizontally from a midpoint 16 of the front edge 14 toward both sides and curves toward the rear of the front member 12. In one example, the front edge 14 extends rearward from the midpoint 16 toward a first side 18 to a rear member 20, and is integral with the rear member 20. In one example, the front edge 14 extends rearward from the midpoint 16 toward a second side 22, which is the opposite side of the device, to an end (closed end) 24. The end 24 is separate and not connected to the rear member 20.

[0030] The leading edge 14 of the front member has a shape that is convexly curved outwardly. In the illustrated example, the leading edge 14 has a curved shape, however, the leading edge 14 can have a different shape and is still within the scope of the torso device of the present disclosure.

[0031] The front member 12 has a rear edge 26 that is vertically disposed and extends laterally or horizontally along a rear side of the front member 12 opposite the front edge 14 from an end 24 of the front edge 14 to an open end 28. The open end 28 is integral with the rear member 20 and forms an integral connection between the front member 12 and the rear member 20. In one example, the rear edge 26 has a shape that is curved inwardly and concavely, so that the rear edge 26 fits against the front of the human torso or waist.

[0032] The front member 12 has an upper surface (table surface) 30 and an opposite lower surface 32. The upper surface 30 and the lower surface 32 extend generally horizontally and parallel to one another along the top and bottom, respectively, of the leading edge 14 and the trailing edge 26 of the front member 12.

[0033] The front member 12 has a thickness between the upper surface 30 and the lower surface 32 that provides a predetermined surface area that prevents inadvertent downward movement of the torso device, e.g., the front member 12, when placed in contact with the front and sides of a user's torso, thereby maintaining the device on the user in a desired position such that the upper surface remains perpendicular to the user's torso (and / or parallel to the surface on which the user is standing or walking) even when the user is standing or walking.

[0034] The front member 12 also has a thickness that provides a desired stiffness to allow a user to perform a particular task or activity, such as working with a laptop, reading, working on a tabletop, eating, etc. Furthermore, as described below, the front member 12 has a predetermined thickness, which, in cooperation with the integral rear member 20 and in cooperation with the shapes and materials of the front member 12 and the rear member 20, allows a desired pressure or compression force to be applied to the torso of a user wearing the torso device. The combination of such pressure or compression force and the surface area of ​​the front member 12 and the contact area with the user's torso maintains the front member 12 in a desired position, such that the front member 12 is perpendicular to the user's torso and / or parallel to the floor surface on which the user stands or walks.

[0035] In one example, the thickness of the front member 12 is about 2 inches or more, preferably about 3 inches to about 8 inches, and more preferably about 4 inches to about 6 inches. In a preferred embodiment, the thickness is about 5 inches. The actual thickness of the front member 12 may vary from the illustrated dimensions depending on the type and stiffness of the material of the front member 12 and / or the particular task or activity being performed by the user, and such thickness variations are within the scope of the present disclosure.

[0036] Although an example has been described in which the front member 12 has a generally constant thickness, the front member 12 may have a different configuration, such as having a non-constant thickness, to provide certain features and / or functionality required for or to facilitate a particular task or activity of the user.

[0037] 6 shows a cross-sectional view along midpoint 16 (see FIG. 1) of an example front member 12 of torso device 10. In this example, front member 12 is configured to have a different or varying thickness between upper surface 30 and lower surface 32 such that it slopes from leading edge 14 to trailing edge 26. Such thickness variation may extend along only a portion of the front member a predetermined distance on either or both sides of midpoint 16, or may extend along the entirety of front member 12.

[0038] In one example, the change in slope or thickness is greater than about ¼ inch, preferably from about ½ inch to about 5 inches, and more preferably from about ¾ inch to about 4 inches. In a preferred embodiment, it is from about 1 inch to about 2 inches.

[0039] In such an example, the upper surface of the front member 12 is inclined inwardly, which is advantageous in that an item or object placed on the upper surface 30 can be moved inward toward the rear edge 26 and the user without easily falling off the torso device, such as by rolling off the leading edge 14.

[0040] In such an embodiment, the trailing edge 26 maintains a predetermined surface area sufficient to maintain the position of the front member 12 relative to the user. Also, while the embodiment in which the thickness of the front member in the vertical direction is not constant is illustrated, the torso device of the present disclosure also includes an embodiment in which the thickness changes stepwise or without an inclined surface.

[0041] As will be described later, the front member 12 of the torso device can be constructed from a single layer of material, but can also be constructed from two or more layers of material. Figure 6 shows an example in which the front member 12 is constructed from two layers of material, specifically, an upper material layer 34 and a lower material layer 36. In this example, the sloping characteristics of the front member 12 are achieved by the upper material layer 34 having a sloping upper surface 30 and a horizontal lower surface 38. The lower surface 38 of the upper material layer 34 is joined to a horizontal upper surface 40 that faces the lower surface 38 of the lower material layer 36, which has a uniform thickness.

[0042] Although a particular embodiment of a torso device in which the front member 12 has a non-constant thickness has been described and illustrated, this is merely one example configuration provided as a reference, and other configurations may be applied to the torso device of the present disclosure. For example, a configuration in which the thickness, as measured along the midpoint 16 of the front member 12, is tapered from the trailing edge 26 to the leading edge 14, i.e., in the opposite direction to that illustrated in FIG. 6, may also be preferred for certain tasks and / or activities. Thus, all configurations of torso devices in which the front member 12 has a non-constant thickness are within the scope of the present disclosure.

[0043] In another example, the torso device 10 is adapted to have an upper surface of the front member 12 that is not tapered and has a non-constant thickness. Figure 7 shows a cross-sectional view of an example of the front member 12 of the torso device 10 taken along the midpoint 16 (see Figure 1). In this example, the front member 12 includes a lip element 42. The lip element 42 projects outwardly from the upper surface 30 a predetermined distance and extends from the leading edge 14 or a portion adjacent to the leading edge 14 toward the trailing edge 26 a predetermined distance.

[0044] The lip element 42 may extend along only a portion of the front member 12, extending a predetermined distance from one or both sides of the midpoint 16, or may extend along the entire front member 12. The lip element 42 may have different configurations, such as a rounded top, a flat top, or a pointed top, depending on the particular task and / or activity of the user.

[0045] In one example, lip element 42 has a height from upper surface 30 of about ¼ inch or more, preferably about 1 inch to about 5 inches, and more preferably about ¾ inch to about 4 inches. In a preferred embodiment, the height is about 1 inch to about 2 inches.

[0046] In such an example, the lip element 42 provided on the upper surface 30 of the front member 12 advantageously ensures that any items or objects placed on the upper surface 30 will not easily fall off the torso device during use, but will instead be positioned on the upper surface 30 between the lip element 42 and the user's torso in contact with the trailing edge 26. As will be described below, the front member 12 of the torso device can be constructed from a single layer of material, or it can be constructed from two or more layers of material.

[0047] Similar to the structure shown in Figure 6, Figure 7 shows an example in which the front member 12 is constructed from two layers of material, specifically an upper layer of material 34 and a lower layer of material 36. In this example, the lip element 42 is achieved by the upper layer of material 34 having the lip element 42, an upper surface 30, and a horizontal lower surface 38. The lower surface 38 of the upper layer of material 34 is bonded to a flat, horizontal upper surface 40 opposite the lower surface 38 of a lower layer 36 having a constant thickness.

[0048] Although a particular embodiment of a torso device having a lip element 42 has been described and illustrated, it is merely one example provided for reference purposes, and other configurations are possible for the torso device of the present disclosure. For example, to better accommodate a particular task and / or activity of a user, the torso device may be provided with a lip element disposed to extend upwardly from or adjacent the trailing edge 26 and transitioning gradually upwardly from the upper surface 30 of the front member 12 toward the front of the user's waist, thereby increasing the surface area of ​​contact between the trailing edge 26 of the front member 12 and the user's torso, thereby better retaining the position of the torso device relative to the user.

[0049] Alternatively, multiple lip elements may be provided on or adjacent each of the leading edge 14 and trailing edge 26 of the front member 12. In some examples of alternative configurations of the torso device of the present disclosure, more than one lip element is provided. Thus, any configuration of the torso device having more than one lip element extending from the front member 12 is within the scope of the torso device of the present disclosure.

[0050] Additionally, although not shown, the torso device of the present disclosure may be configured to include a combination of both a non-uniform front member such as that shown in Figure 6, and a lip element of the front member such as that shown in Figure 7. Accordingly, all such combinations of features are within the scope of the torso device of the present disclosure.

[0051] 1, the front member 12 has a horizontal width between the leading edge 14 and the trailing edge 26 that varies with the location of measurement. As shown, the width of the front member 12 increases from a minimum at the end 24, reaches a maximum at the midpoint 16, and decreases in width from the midpoint 16 to the open end 28 where it is integral with the rear member 20.

[0052] In one example, the width of the front member 12 at the midpoint 16 is about 3 inches or more, preferably about 4 inches to about 16 inches, and more preferably about 6 inches to about 12 inches. In a preferred embodiment, the width is about 9 inches.

[0053] The actual measurement of the width of the front member 12 at the midpoint 16 may vary from the illustrated dimensions depending on the particular task and / or activity of the user, and such dimensional variations are within the scope of this disclosure. The width of the front member 12 also varies depending on the amount of pressure or compression applied to the user's torso during use to maintain position of the torso device relative to the user's torso.

[0054] The front member 12 has a maximum horizontal length measured perpendicular to the midpoint 16 along the upper surface 30. The length and width of the front member cooperate to provide a desired compressive or compressive force against the user's torso to properly position the torso device relative to the user and enable the user to perform tasks and / or activities on the upper surface 30.

[0055] In one example, the maximum length of the front member 12 between the leading edge 14 and the trailing edge 26 is greater than or equal to 14 inches, preferably between about 16 inches and about 26 inches, and more preferably between about 18 inches and about 24 inches. In a preferred embodiment, the maximum length is about 20 inches.

[0056] The length dimension of the front member 12 described above is for reference only, and the torso device of the present disclosure may be of different sizes depending on the desired amount of inward pressure or compression applied to the user's torso and / or the particular task and / or activity of the user, and such different sized torso devices are within the scope of the torso device of the present disclosure.

[0057] In one example, the top surface 30 of the front member 12 of the torso device 10 can include one or more optional surface features formed and integrated as part of the top surface. Such surface features are shaped and sized and / or positioned to facilitate a user performing a particular task and / or activity when using the torso device. For example, such surface features may take the form of one or more protrusions configured to assist in holding or supporting a laptop or tablet. Alternatively, the top surface 30 can be configured to accommodate contact, connection, or attachment with a separate element that functions to facilitate use of a particular user device or element.

[0058] Thus, all surface features or other elements provided on the upper surface 30 of the front member 12, regardless of shape, size, and / or arrangement, are within the scope of the torso device of the present disclosure.

[0059] The rear member 20 of the torso device 10 extends laterally or horizontally from a portion integrally connected to the open end 28 of the front member 12, has an integral structure with the front member 12, and extends opposite the rear edge 26 of the front member 12 to form a user opening (opening cavity) 46.

[0060] A user opening (central opening) 46 is formed or defined between the rear edge 26 of the front member 12, the open end 28 of the front member 12, and a vertically disposed leading edge 48 of the rear member 20. The user opening 46 is accessed through an open passageway formed between the end 24 of the front member 12 and the rear member 20.

[0061] In one example, the leading edge 48 of the rear member 20 is configured to be flat or planar so as to contact the back of the user's torso substantially across its width when the user's torso or waist is at the position of the opening 46.

[0062] In one example, the horizontal length, measured along the plane of the leading edge 48 of the rear member 20, along the user opening 46 is about 10 inches or more, preferably about 12 inches to about 18 inches, and more preferably about 13 inches to about 16 inches. In a preferred embodiment, the horizontal length is about 14 inches.

[0063] The actual measurement of the horizontal length of the leading edge 48 of the rear member 20 may vary from the illustrated dimensions depending on the desired contact area with the user, and such dimensional variations are within the scope of this disclosure.

[0064] 2 and 3 illustrate the torso assembly 10, the end 24 of the leading edge 14 of the front member 12, and the positional relationship of the end 24 of the front member 12 to the rear member 20. As shown, the rear member 20 includes a side element 50 located at an end of the rear member 20 opposite the open end 28 of the front member 12. The side element 50 is integral with the leading edge 48 of the rear member 20 and extends laterally or horizontally a predetermined distance from the leading edge 48 to an end 52 of the rear member 20.

[0065] The side elements 50 of the rear member 20 are adjacent to the outer surface of the end 24 of the front member 12 and have a curved shape that curves inwardly toward the leading edge 14 of the front member 12 adjacent and opposite to, but not joined to, the side elements 50. In one example, the thickness between the upper surface 53 and the lower surface 54 of the side elements 50 is approximately the same as the thickness of the adjacent and opposing portions of the leading edge 14 of the front member 12, thereby providing continuity between the side elements 50 and the leading edge 14 of the front member 12 when the device is worn by a user.

[0066] The torso device of the present disclosure is characterized by the integral construction of the front member 12 and rear member 20 through the open end 28, the configuration of the opposing surfaces of the front member 12 and rear member 20 forming the opening 46 that provides a desired amount of surface area for contacting the user's torso, which cooperate to maintain the front member 12 in a substantially perpendicular orientation relative to the user's torso, thereby maintaining the torso device in a desired position, even when the user is moving, for example, when the user moves from a sitting position to standing, walking, or standing, etc. This allows the torso device to maintain a desired position relative to the user without the need for additional support by the user's hands or other elements or members.

[0067] In one example, when the user's torso is placed in the opening 46, the torso device contacts at least about 75%, and preferably at least about 85%, of the user's torso inside the opening 46, and the surface area in contact with the user's torso and the compressive or compressive force on the user's torso can maintain the torso device in a desired position.

[0068] 1 and 2, in the relaxed state, the end 24 of the front member 12 of the torso device 10 is biased inward toward the rear edge 26, so that it contacts the front edge 48 of the rear member 20 or is spaced a small distance, about 0.5 inches to about 1 inch (1.27 cm to about 2.54 cm), from the front edge 48 of the rear member 20 and is disposed inside the side element 50 of the rear member 20. Therefore, in the relaxed state, the side element 50 extends along the front surface of the front member 12, away from the end 24.

[0069] The inward bias of the end 24 of the front member 12 towards the rear member 20, the inward position of the end 24 of the front member 12 on the side element 50 of the rear member 20, and the curved surface of the rear edge 26 of the front member 12 facing the front edge 48 of the rear member 20 ensure that a suitable pressure or compression force is applied to the torso of the user when the user is positioned inside the opening 46, and that a suitable surface area of ​​contact is achieved between the torso of the user and the torso device, so that the torso device is properly maintained on the torso of the user while the user is performing an action such as walking or standing, with the front member 12 perpendicular to the torso and / or parallel to the surface on which the user is standing or walking.

[0070] A feature of the torso device of the present disclosure is that the proper position of the torso device relative to the user is maintained without the user having to use their arms or hands to maintain or adjust the position of the torso device.

[0071] In one example, the torso device is configured to enable measurements to determine the force as the end 24 of the front member 12 and the rear member 20 move away from one another from a relaxed state. Measurements are performed by maintaining the position of the front member 12 in a fixed position and moving the rear member 20 away from the front member 12 from the relaxed state. A tensile force gauge is attached to the rear member 20 where the side elements 50 extend from the leading edge 48 of the rear member 20. Forces are measured by the tensile force gauge as the rear member 20 moves away from the relaxed state.

[0072] As the rear member 20 is pulled away from the front member 12, the following forces are measured as a function of the angle of the rear member 20 relative to the fixed front member 12 (i.e., the angle relative to an axis along the length of the fixed front member 12): for angles between about 1 degree and about 4 degrees, the force is about 0.2 ft·lb (foot-pound, about 0.27 N·m), for angles between about 10 degrees and about 15 degrees, the force is about 0.3 ft·lb (about 0.41 N·m), for angles between about 20 degrees and about 30 degrees, the force is about 0.4 ft·lb (about 0.54 N·m), for angles between about 40 degrees and about 50 degrees, the force is about 0.5 ft·lb (about 0.68 N·m), and for angles between about 51 degrees and about 60 degrees, the force is about 0.6 ft·lb (about 0.70 N·m). b (approximately 0.81 N·m), from about 62 degrees to about 74 degrees, it is approximately 0.7 ft·lb (approximately 0.95 N·m), from about 75 degrees to about 80 degrees, it is approximately 0.8 ft·lb (approximately 1.08 N·m), from about 81 degrees to about 84 degrees, it is 0.9 ft·lb (approximately 1.22 N·m), from about 85 degrees to about 87 degrees, it is 1.0 ft·lb (approximately 1.36 N·m), and from about 88 degrees to about 90 degrees, it is 1.1 ft·lb (approximately 1.49 N·m).

[0073] Based on this force measurement information, the threshold force required to move the end 24 of the front member 12 from a relaxed state away from the leading edge 48 of the rear member 20 a distance of about 2 inches to about 4 inches is at least 0.2 ft·lb (about 0.27 N·m), a distance that would not allow a user to access the opening 46. The threshold force required to move the end 24 from a relaxed state away from the leading edge 48 a distance of about 12 inches is at least 0.4 ft·lb (about 0.54 N·m), a distance that is sufficient to allow a user to access the opening 46.

[0074] Based on this measurement information, the torso device can apply a compressive force to the user's torso positioned in opening 46 of at least 0.2 ft·lb (approximately 0.27 N·m), preferably about 0.3 ft·lb to about 0.8 ft·lb (approximately 0.41 N·m to about 1.08 N·m), and more preferably about 0.4 ft·lb to about 0.7 ft·lb (approximately 0.54 N·m to about 0.95 N·m).

[0075] Although the torso device of the present invention is capable of providing the above force measurements, assuming suitable measurements and suitable elastic materials, different sizes of the torso device and different types of elastic materials may provide different force measurements, and different compression forces based thereon are also within the scope of the torso device of the present disclosure.

[0076] 3 and 5 show an example of the torso device 10 and the rear member 20 with an extension element 56. The extension element 56 extends laterally or horizontally along the plane of the front edge 48 of the rear member shown in FIG. 1 and FIG. 2. The extension length is about 10 inches or more, preferably about 12 inches to about 18 inches, and more preferably about 13 inches to about 16 inches. In a preferred embodiment, the extension length is about 14 inches. The extension element 56 extends upward from the front edge 48 of the rear member 20 by a predetermined distance.

[0077] In cooperation with the leading edge 48 of the rear member 20, the extension element 56 contacts the back of the user's torso to provide an appropriate amount of surface area to enable the torso device to maintain position relative to the user when the user is moving, such as when the user rises from a sitting position, walks, or remains standing.

[0078] Additionally, the extension element 56 and its increased contact area above the user's torso prevents the front member 12 from sagging downward, further maintaining proper vertical alignment of the front member 12 relative to the user's torso.

[0079] In one example, the extension element 56 is vertically oriented and has a leading edge 58 (see FIGS. 1 and 2) that has a similar extent as the leading edge 48 of the rear member 20, forming a uniform vertical plane along the rear member 20, such that the rear member 20 and the extension element 56 function as described above. In an alternative embodiment, the extension element 56 can be configured such that its leading edge 58 is positioned inboard or outboard relative to the remainder of the leading edge 48 of the rear member 20, allowing for an adjustable degree of functionality to be provided.

[0080] In one example, the total vertical height of the rear member 20 including the extension elements 56 (the distance between the lower surface 60 of the rear member 20 and the upper surface 62 of the extension elements 56) is about 6 inches or more, preferably about 7 inches to about 14 inches, and more preferably about 8 inches to about 13 inches. In a preferred embodiment, this height is about 9 inches.

[0081] The actual height measurement may vary from the illustrated dimensions depending on the thickness of the front member 12 and / or the rear member 20 and / or the materials applied to the torso device. Such dimensional variations are within the scope of the torso device of the present disclosure. For example, in certain embodiments, the combined height of the rear member 20 and the extension element 56, measured as described above, is at least 1.5 times, and preferably at least 2 times, the thickness of the front member 12. In other specific embodiments, the combined height of the rear member 20 and the extension element 56 is about 12 inches or greater to fully provide the improved functionality described above.

[0082] As shown in Figures 3 and 4, in one example, the width between the leading edge 58 and the vertically disposed trailing edge 64 of the extension element 56 is similar to the width of the rear member 20 (measured between the leading edge 48 and the trailing edge 66 of the rear member 20). In one example, the side elements 50 of the rear member 20 have the same width as the rear member 20. In one example, the width of the extension element 56 is at least about 1 / 2 inch, preferably about 3 / 4 inch to about 4 inches, and more preferably about 1 inch to about 3 inches. In a preferred embodiment, the width is about 2 inches.

[0083] This width measurement may vary from the illustrated dimensions depending on factors such as the size and shape of other elements or features and / or materials of a particular construction, and such dimensional variations are within the scope of the torso device of the present disclosure.

[0084] The torso device of the present disclosure can be constructed from different materials to provide a suitable balance of surface area, friction surface, stiffness, compression force, and / or comfort when worn by the user and / or provide the desired functionality for the performance of the user's task and / or activity. In one example, the torso device is preferably formed from an elastically deformable elastic material such as foam or sponge. Such elastic material can be deformed by compression force to provide a relatively high friction surface against the user's torso, which, in addition to the surface area and compression force characteristics, can help to hold the torso device in a suitable position during use.

[0085] In one example, the torso device is constructed from a foam material that provides a good balance of friction surface, stiffness, and comfort to the user during use. The type and density of the foam material can vary depending on the particular configuration of the torso device. For example, if the torso device is constructed from a single foam material, the foam material should be selected from the perspective of providing a balance between friction surface and stiffness level, as well as providing comfort to the user. If a single foam material is used, a suitable foam material has a hardness rating of 30 / 36 ILD and a density rating of 2.0 (approximately 32.0 kg / m 3 ) foam materials.

[0086] However, other foam materials, such as closed cell foams, may be used in such single foam constructions. The torso device of the present disclosure may be constructed from a particular type of resilient material, but may also be constructed to have an inflatable structure that is partially or fully air filled to provide the surface area, compression or compressive force, and stiffness functions described above.

[0087] In one example, the torso device may be constructed from two or more different foam materials. The torso device 10 shown in FIG. 5 is constructed using at least two different foam materials. The torso device 10 includes a first foam material 70 extending from the undersides of the front member 12 and the rear member 20, and a second foam material 72 extending from the first foam material 70 to the upper surface 30 of the front member 12.

[0088] In one example, the first foam material 70 has a different density than the second foam material 72. In a preferred embodiment, the first foam material 70 has a greater density than the second foam material 72 to provide a desired increase in stiffness, rigidity, and traction. The second foam material 72 that comprises the upper surface 30 can provide a desired level of softness or comfort to enable a particular task and / or activity of the user.

[0089] Suitable foam materials for constructing the first foam material 70 have a Shore A hardness of about 30 to about 100 and a compressibility of about 10 kg / m 3 ~about 30kg / m 3 In a preferred embodiment, the first foam material 70 has a Shore A hardness of about 80 and a density of about 20 kg / m 3 Suitable foam materials for constructing the second foam material 72 have a Shore A hardness of about 15 to about 50 and a density of about 5 kg / m 3 ~about 25kg / m 3 In a preferred embodiment, the second foam material 72 has a Shore A hardness of about 35 and a density of about 18 kg / m 3 has a density of

[0090] In one example, the first foam material 70 constitutes 50% or more of the thickness of the front and rear members not including the extension elements, and the second foam material 72 constitutes 50% or less of the thickness not including the extension elements. In one example, the first foam material is preferably about 55%-95% of the total thickness, and about 65%-90% of the total thickness. In a preferred embodiment, it forms about 80% of the total thickness, and the second foam material forms the remaining thickness not including the extension elements. In general, it is desirable for the torso device to include more of the higher density foam material to provide greater hardness and rigidity while also providing a frictional surface. All of these are preferred to ensure that the device is maintained in a desired position relative to the user during use. The actual amounts or percentages of the first foam material 70 and the second foam material 72 used to form the torso device of the present disclosure will vary depending on the specific different characteristics of the two different foam materials used, and such variations are also within the scope of the torso device of the present disclosure.

[0091] In the example described above in which the torso device is formed from two different foam materials 70 and 72, the extension element 56 may be formed from one of the two different foam materials 70 and 72, or may be formed from a third foam material having a density different from the densities of both the first and second foam materials. For example, the extension element 56 may be formed from a foam material having a density higher than the density of the first foam material 70, or the extension element 56 may be formed from a foam material having a density that is between the densities of the first and second foam materials, or the extension element may be formed from a foam material having a density lower than the density of the second foam material 72.

[0092] In one example, where the first and second foam materials each have the specific density characteristics described above, the extension element 56 is formed from a second foam material 72 having a relatively low density to provide improved comfort and conformability to the user. Alternatively, the extension element 56 is formed from a third foam material having a density higher than that of the second foam material and lower than that of the first foam material, thereby providing a medium firmness that can improve support to the waist while still providing some flexibility and comfort.

[0093] Although specific examples of torso devices formed from two or more different foam materials have been disclosed, the torso devices of the present disclosure may be formed from different types of foam materials and / or using different types of foam materials in different proportions than those described above. For example, a torso device may have an expandable structure as described above to achieve the same or similar purposes and / or functions as those described above, and all such embodiments of a torso device so formed and configured are within the scope of the torso device of the present disclosure. The different foam materials used to form the torso devices of the present disclosure may be formed and combined by conventional methods, such as, for example, molding or adhesive assembly processes.

[0094] 8 illustrates an example of a torso device 10 of the present disclosure with an optional inner cover 80 disposed over at least a portion of the torso device. In one example, the inner cover 80 is formed from a moisture resistant or moisture proof material for the purpose of protecting the underlying foam material. Useful and suitable materials for forming the inner cover 80 include film materials made of plastics and other types of polymers that have moisture resistant or moisture proof properties and may be transparent or non-transparent.

[0095] In one example, the inner cover 80 is configured to fit over the front member 12, and in a preferred embodiment, the inner cover 80 is configured to fit over or cover the entire front member 12. In one example, the inner cover 80 is a removable element provided in the form of a sleeve having an open end 82 and a closed end 84, where the open end 82 is configured to fit around the open end 28 of the leading edge 14 of the front member 12 shown in FIG. 1, and the closed end 84 is configured to fit around the end 24 of the front member shown in FIG.

[0096] The inner cover 80 includes a zippered connection 86 that extends from the open end 82 a partial length along the bottom of the inner cover 80. The zippered connection 86 of the inner cover 80 is unzipped into two zipper sections before the inner cover 80 is attached to the front member 12, thereby allowing the open end 28 of the front member 12 and a majority of the front member 12 adjacent the midpoint 16 to be contained within the inner cover 80. By attaching the inner cover 80 to the front member 12, positioning the open end 82 of the inner cover 80 around the open end 28 of the front member 12, and engaging the two zipper sections to close the zipper, the front member 12 is covered and protected by the inner cover 80. In this manner, the inner cover 80 is configured to be removable for cleaning or replacement purposes, as needed.

[0097] In one example, the inner cover 80 is manufactured by a conventional process, such as molding. Although a particular configuration of the inner cover 80 has been shown and disclosed, the inner cover may be configured differently for the same or similar purpose of protecting the foam material of the torso device underneath from moisture. All such different inner cover configurations are within the scope of the torso device of the present disclosure. Additionally, although the inner cover 80 has been disclosed as functioning to protect the front member 12 of the torso device from moisture, the use of an inner cover or additional inner covers may be configured or manufactured to protect the rear member 20 from moisture, and such use of an inner cover or additional inner covers is also within the scope of the present disclosure.

[0098] 9 illustrates an example of a torso device 10 of the present disclosure with an exterior cover 90 disposed thereon. In one example, the exterior cover 90 is formed from a material suitable for constructing the exterior surface of the torso device to provide a desired frictional surface for the surface area of ​​the torso device that contacts the torso of a user during use. Suitable materials for forming the exterior cover 90 include materials such as fibers, fabrics, plastics, polymers, and combinations thereof. In one example, the exterior cover 90 is formed from a fiber material.

[0099] In one example, the exterior cover 90 is configured to fit over the torso device. In a preferred embodiment, it fits over the entire torso device, i.e., over both the front member 12 and the rear member 20 as shown in FIG. 1. In such a preferred embodiment, the exterior cover 90 not only functions to form the exterior surface of the torso device, but also provides mounting / fixing locations and mounting / fixing mechanisms, as described below. In one example, the exterior cover 90 has an upper portion sewn to fit over the upper surface, front edge, and rear edge of both the front member 12 and the rear member 20, including the extension element 56, and a lower surface configured to fit over the lower surface of the front member 12 and the rear member 20.

[0100] Along an edge of the front member 12 at the intersection of the leading edge 14 of the front member 12 and the underside 32 (see FIG. 1 ) and along an edge of the rear member 20 at the intersection of the trailing edge 66 of the rear member 20 and the underside 60 (see FIG. 4 ), the exterior cover 90 is provided with a zippered connection 92 used to connect the top and bottom. The exterior cover 90 includes a first closed end 94 configured to receive the end 24 of the leading edge 14 of the front member 12 (see FIG. 1 ) and a second closed end 96 configured to receive the side element 50 of the rear member 20 (see FIG. 1 ). The zippered connection 92 extends between the first closed end 94 and the second closed end 96 to allow for the torso device to be received by unzipping the zipper into two zipper sections prior to attachment of the exterior cover 90 to the remainder of the front member 12 and rear member 20.

[0101] In one example, the outer cover 90 is manufactured by conventional processes depending on the type of material used, for example, when formed from a textile material, the outer cover 90 is manufactured by a sewing process. Although a particular configuration of the outer cover 90 has been shown and disclosed, the outer cover may be in different configurations for the same or similar purposes discussed above, and all such different outer cover configurations are within the scope of the present disclosure.

[0102] 9-11 show the torso device 10 of the present disclosure with the exterior cover 90 attached. The exterior cover 90 is configured to include a first attachment element 98. The first attachment element 98 may, for example, provide an additional mechanism for securing the torso device around the waist of a user in addition to the mechanism for providing the surface area and compressive force of the torso device, thereby improving the convenience of the torso device.

[0103] The first attachment element 98 is connected to a side end surface 100 of the exterior covering 90 that is disposed over the side element 50 (see FIG. 1 ) of the rear member 20. In one example, the first attachment element 98 is provided in the form of a male snap connection member 102 attached to one end of a loop of fabric 104, the other end of which is attached to the exterior covering 90. In one example, the loop of fabric 104 is sewn to the exterior covering 90.

[0104] The exterior cover 90 extends along a portion of the length of the leading edge 14 of the front member 12 and is configured to include an attachment location 106 located a predetermined distance from the end 24 of the front member 12 (see FIG. 1).

[0105] The second attachment element 108 is provided in the form of a female snap connection member 110 attached to one end of a loop of fabric 112 having a length of fabric belt 114 attached thereto. In one example, the fabric belt 114 is configured to have a desired length to allow connection to the attachment location 106, and allows the torso device 10 to be more securely attached around the torso of a user by engaging the male snap connection member 102 with the female snap connection member 110.

[0106] In one example, the attachment locations 106 comprise Velcro® material configured to be detachable with the Velcro® material of the fabric belt 114 .

[0107] With this configuration, the user can first urge the inwardly curved end 24 of the front member 12 away from the side elements 50 of the rear member 20, thereby allowing the user to insert his / her torso or waist into the opening 46, which is the space between the front member 12 and the rear member 20. As a result, the torso device 10 is worn by the user. Once the user's waist is placed in the opening 46, the torso device 10 elastically returns to the position to which it is urged relative to the user, as described above, and applies, for example, sufficient compressive force to the user to maintain the position of the front member 12 of the torso device 10 perpendicular to the user's torso while walking or standing.

[0108] Optionally, the male snap members 102 and the female snap members 110 can be connected together to further secure the torso device 10 to the user. If the attachment position of the fabric belt 114 has not yet been established, the male snap members 102 and the female snap members 110 can be joined together before attaching the fabric belt 114 to the attachment position 106. In this case, the user attaches the fabric belt 114 to the attachment position 106 in a position that provides the desired secure fit.

[0109] Alternatively, if the user has already worn the torso device 10, the fabric belt 114 may already be attached to the attachment location 106 in a location that provides the desired secure fit, in which case the user need only engage the male snap connection member 102 and the female snap connection member 110 to further securely fasten the torso device 10.

[0110] Thus, a feature of the torso device of the present disclosure is the ability to further secure the torso device to the user and further ensure that the torso device does not shift position when the user moves during use, for example, when the user moves from a seated position to a standing position, when walking, when standing, etc. Although specific types of connecting members and attachments of the connecting members to the exterior cover have been disclosed, other attachment mechanisms that function to form any attachment that allows the user to wear the torso device and further secures the torso device around the waist of the user are within the scope of the torso device of the present disclosure.

[0111] FIG. 9 shows an example of the use of an optional attachment element 116 on the outer cover 90 of the torso device. In one example, the optional attachment element 116 is configured as needed to facilitate or add a degree of functionality to the torso device 10 for the user. In one example, the attachment element 116 is configured in the form of a bag or pocket for storing accessories therein. In one example, the attachment element 116 is attached in a location that is easily accessible to the user, for example, along a portion of the front edge 14 (see FIG. 1) of the front member 12. In one example, the attachment element 116 is a bag formed of the material that constitutes the outer cover 90. The attachment element 116 is attached to the outer cover by conventional connecting means, such as stitching, buttons, Velcro, etc., to provide a permanent or removable connection with the outer cover.

[0112] Although any exemplary attachment element 116 has been specifically described and illustrated as having a particular configuration, different attachment elements may be configured to perform the same or similar functions, and all such different configurations of attachment elements for use with the outer cover are within the scope of the torso device of the present disclosure.

[0113] 12 illustrates a torso device 10 including an outer cover 90 and further including a pair of optional straps 120 connected to the outer cover 90. In one example, the straps 120 are formed of a suitable material useful for placing or wearing over a user's shoulders to provide additional vertical support to the torso device 10 when in use. Suitable materials for forming the straps 120 include materials such as textile, fabric, leather, plastic, polymer, and the like. In one example, the straps 120 are formed from a textile or fabric material, such as a textile or fabric belt.

[0114] In one example, each strap 120 extends from an attachment location along the trailing edge 66 of the rear member 20, over the top of the extension element 56, to an attachment location 122 along the leading edge 14 of the front member 12. In one example, the attachment location 122 may be configured to permanently attach the strap 120 to the outer covering 90, such as by sewing, or may be configured to removably attach the strap 120 to the outer covering 90, such as by buttons, Velcro®, or the like.

[0115] In one example, each strap 120 includes a front portion 124 that extends a predetermined length from the front member 12 and a rear portion 126 that extends a predetermined length from the rear member 20. Attachment elements 128 in the form of buckles, male and female snap connections, or the like, are attached to one or both ends of the front and rear strap portions 124, 126 to provide a releasable attachment between the front and rear strap portions 124, 126 and / or to adjust the length of the strap 120 to provide a custom fit for a user.

[0116] Straps 120 configured in this manner provide a desired degree of vertical support for the torso device when worn by a user. If desired, straps 120 are configured so that a cover, not shown, can be placed, for example, over a portion of the strap in front of the user, to provide a degree of privacy for the user or the like. Although a particular configuration of straps 120 has been described and illustrated, straps of different configurations can be developed for the same or similar purposes, and all such different strap configurations are within the scope of the torso device of the present disclosure.

[0117] 13 and 14 are diagrams illustrating the use of the torso device 10 by a user. Specifically, FIG. 13 illustrates the use of the torso device 10 by a user while walking, where the contact surface area provided by the front member 12, the rear member 20, and the extension elements 56, in combination with the compressive forces applied to the torso of the user by the front member 12 and the rear member 20 of the torso device, cooperate to extend the front member 12 substantially perpendicular to the torso of the user or parallel to the floor surface 130 on which the user is walking, thereby maintaining the torso device 10 in a desired position relative to the user.

[0118] 14 illustrates the use of torso device 10 by a user during standing, where the contact surface area provided by front member 12, rear member 20, and extension elements 56, in combination with the compressive forces exerted by front member 12 and rear member 20 on the user's torso, causes front member 12 to extend substantially perpendicular to the user's torso or parallel to a floor surface 130 on which the user is walking, maintaining torso device 10 in a desired position relative to the user. In this example, torso device 10 is being used to support a laptop computer 132 on the upper surface 30 of front member 12.

[0119] Various embodiments of the torso device of the present disclosure have been described with reference to the drawings. The description of the embodiments is for illustrative purposes only and does not limit the scope of the torso device of the present disclosure. Therefore, those skilled in the art can make various modifications to the torso device of the present disclosure without departing from the scope of the claims.
