Patent Application
20170265643
Embodiments of the present invention are generally related to a user work station system and method of use and in particular, to an ergonomic and fully-adjustable user work station.
In various industrial applications, workers are required to remain in one location, either sitting or standing, and work on a continuing stream of required tasks. This might occur on a factory assembly line, in a food-processing industry or even a clerical function, such as a mail room or the like.
For many years a worker in such a position would have been expected to stand, but sitting in a fixed position has become common. The seats provided to such workers, however, are typically no more than institutional office seating, and often do not provide adequate support or comfort to a worker. Neither a standing nor a sitting position may be sustained for long periods of time unless the worker is provided with adequate trunk support to relieve postural muscle fatigue and strain, which may be adjusted for the comfort of the user.
Historically the trunk support in a chair or stool has been posterior, and facilitates spine flexion, especially if the hip angle is 90 degrees or less. Prolonged sitting in spine flexion imposes excessive stress on the posterior lumbar spinal structures: ligaments, facets and discs. Prolonged spine flexion also promotes forward head posture, which has been associated with increased neck pain. The ability to increase the hip angle and provide minimal anterior trunk and neck support is unique. Stationery stands are currently available but do not provide adequate trunk support, do not permit relocation of the device to another position to accommodate postural fatigue and individual anatomical differences.
The invention of this disclosure addresses these problems and solves these needs. A user work station a/k/a work stand is disclosed which provides for the comfort, stability and support of a user during the completion of required tasks. The work station adjusts to accommodate differing working positions and postural adaptations and, in one embodiment, may be conveniently relocated.
It is one aspect of the present invention to provide an ergonomic and fully-adjustable user work station system and method of use.
In one embodiment, the system provides a work station apparatus for a user comprising: a base; a stool comprising a seat, the stool interconnected with the base and extending in a vertical direction; a first mast extending in a vertical direction and interconnected with the base; and a work surface element interconnected with a proximal portion of the first mast; wherein the work surface element may be reached by the user when the user is seated on the stool. In one embodiment, the work station apparatus further comprises an adjustable anterior chest support and head support.
The present disclosure can provide a number of advantages depending on the particular aspect, embodiment, and/or configuration.
The phrases “at least one”, “one or more”, and “and/or” are open-ended expressions that are both conjunctive and disjunctive in operation. For example, each of the expressions “at least one of A, B and C”, “at least one of A, B, or C”, “one or more of A, B, and C”, “one or more of A, B, or C” and “A, B, and/or C” means A alone, B alone, C alone, A and B together, A and C together, B and C together, or A, B and C together.
The term “a” or “an” entity refers to one or more of that entity. As such, the terms “a” (or “an”), “one or more” and “at least one” can be used interchangeably herein. It is also to be noted that the terms “comprising”, “including”, and “having” can be used interchangeably.
The term “automatic” and variations thereof, as used herein, refers to any process or operation done without material human input when the process or operation is performed. However, a process or operation can be automatic, even though performance of the process or operation uses material or immaterial human input, if the input is received before performance of the process or operation. Human input is deemed to be material if such input influences how the process or operation will be performed. Human input that consents to the performance of the process or operation is not deemed to be “material.”
The term “computer-readable medium” as used herein refers to any storage and/or transmission medium that participate in providing instructions to a processor for execution. Such a computer-readable medium is commonly tangible, non-transitory, and non-transient and can take many forms, including but not limited to, non-volatile media, volatile media, and transmission media and includes without limitation random access memory (“RAM”), read only memory (“ROM”), and the like. Non-volatile media includes, for example, NVRAM, or magnetic or optical disks. Volatile media includes dynamic memory, such as main memory. Common forms of computer-readable media include, for example, a floppy disk (including without limitation a Bernoulli cartridge, ZIP drive, and JAZ drive), a flexible disk, hard disk, magnetic tape or cassettes, or any other magnetic medium, magneto-optical medium, a digital video disk (such as CD-ROM), any other optical medium, punch cards, paper tape, any other physical medium with patterns of holes, a RAM, a PROM, and EPROM, a FLASH-EPROM, a solid state medium like a memory card, any other memory chip or cartridge, a carrier wave as described hereinafter, or any other medium from which a computer can read. A digital file attachment to e-mail or other self-contained information archive or set of archives is considered a distribution medium equivalent to a tangible storage medium. When the computer-readable media is configured as a database, it is to be understood that the database may be any type of database, such as relational, hierarchical, object-oriented, and/or the like. Accordingly, the disclosure is considered to include a tangible storage medium or distribution medium and prior art-recognized equivalents and successor media, in which the software implementations of the present disclosure are stored. Computer-readable storage medium commonly excludes transient storage media, particularly electrical, magnetic, electromagnetic, optical, magneto-optical signals.
The terms “determine”, “calculate” and “compute,” and variations thereof, as used herein, are used interchangeably and include any type of methodology, process, mathematical operation or technique.
The term “means” as used herein shall be given its broadest possible interpretation in accordance with 35 U.S.C., Section 112, Paragraph 6. Accordingly, a claim incorporating the term “means” shall cover all structures, materials, or acts set forth herein, and all of the equivalents thereof. Further, the structures, materials or acts and the equivalents thereof shall include all those described in the summary, brief description of the drawings, detailed description, abstract, and claims themselves.
The term “module” as used herein refers to any known or later developed hardware, software, firmware, artificial intelligence, fuzzy logic, or combination of hardware and software that is capable of performing the functionality associated with that element.
The term “screen,” “touch screen,” or “touchscreen” refers to a physical structure that includes one or more hardware components that provide the device with the ability to render a user interface and/or receive user input. A screen can encompass any combination of gesture capture region, a touch sensitive display, and/or a configurable area. The device can have one or more physical screens embedded in the hardware. However a screen may also include an external peripheral device that may be attached and detached from the device. In embodiments, multiple external devices may be attached to the device. Thus, in embodiments, the screen can enable the user to interact with the device by touching areas on the screen and provides information to a user through a display. The touch screen may sense user contact in a number of different ways, such as by a change in an electrical parameter (e.g., resistance or capacitance), acoustic wave variations, infrared radiation proximity detection, light variation detection, and the like. In a resistive touch screen, for example, normally separated conductive and resistive metallic layers in the screen pass an electrical current. When a user touches the screen, the two layers make contact in the contacted location, whereby a change in electrical field is noted and the coordinates of the contacted location calculated. In a capacitive touch screen, a capacitive layer stores electrical charge, which is discharged to the user upon contact with the touch screen, causing a decrease in the charge of the capacitive layer. The decrease is measured, and the contacted location coordinates determined. In a surface acoustic wave touch screen, an acoustic wave is transmitted through the screen, and the acoustic wave is disturbed by user contact. A receiving transducer detects the user contact instance and determines the contacted location coordinates.
The term display” refers to a portion of one or more screens used to display the output of a computer to a user. A display may be a single-screen display or a multi-screen display, referred to as a composite display. A composite display can encompass the touch sensitive display of one or more screens. A single physical screen can include multiple displays that are managed as separate logical displays. Thus, different content can be displayed on the separate displays although part of the same physical screen.

In one embodiment, an ergonomic, fully adjustable work station 20 is described in which a base provides: a) an adjustable semi-standing or sitting chair with inflatable seat to allow pelvic motion; b) optional adjustable chest and head supports and c) an adjustable desk surface with arm support to hold a keyboard or laptop computer device; and d) rungs at various levels for optional foot support. The design allows: (a) the body to be positioned from seated to semi-standing to standing in various hip angles to promote neutral spine and reduce disc and spine compression forces typically found with conventional sitting; (b) postural muscles of the back and neck to relax with anterior chest and head support; and (c) the pelvis to move and continually redistribute forces on the spine with the inflated bladder seat.
The base member 1 may have any number of suitable geometries so long as the primary function of the work stand, dissipating the forces placed on the user, is met. In the illustrated embodiment, the work stand base 1 is comprised of a planar underside 21. This planar underside 21 spreads in a horizontal plane and is designed to support a user employing the work stand 20 and dissipate the forces placed on the work stand 20 by a user.
The work station 20 may further comprise a work surface mast 2. Work surface mast 2 is a central support fixedly attached to work stand base 1 at a single rotational connection and has an external telescopic column 23 and work surface telescopic column 24 of which work surface 3 is fixedly attached. Work surface mast 2 also defines a cavity to surround and support the single rotational connection and interfacing walls between work stand base 1 and work surface mast 2.
In addition, the work stand 20 comprise a tractive footpad 22 which is preferably fixedly attached to some or all of the entire top surface of the base member 1 as shown. “Tractive” here means a surface that provides traction or frictional resistance, thereby providing an anti-skid or anti-slip surface.
In one embodiment, the work station 20 comprises additional horizontal foot rests 11 affixed to the sides of the work surface mast 2, an alternative to resting feet or standing on the tractive footpad 22 surfaces.
One skilled in the art would recognize that various other geometries could be employed to provide a suitable work station base 1. Further, work stand base 1 may be provided by a member securely affixed to the work surface, as known to the prior art, although some objects of the present invention would not be obtained thereby.
The work surface mast 2, as depicted in for example
The work surface mast 2 further includes a provision for the attachment of chest support 4, illustrated as being mounted into a telescopic channel within the user-side of external telescopic column 23.
Modular stool 6 as in
The modular stool sleeve 26 is permanently capped at its end with a key shaped feature that slides and fixedly engages with the modular stool horizontal positioner 13 as illustrated in
With continued reference to
In one embodiment, the anterior chest support system (comprising chest support pad 16 and chest support mast 4) is further adjustable in addition to height and radial position i.e. chest support radial adjustment 27. For example, the chest support system is adjustable in flexibility or stiffness, such that the support (e.g. the mast 4) may “give” or flex to varying degrees based on user preference and/or user profile. Also, the chest support 16 may adjust in any of three (3) rotational directions, i.e. in pitch, roll and yaw, either to a fixed angle or an angle that adjusts/adapts once engaged with the chest of a user. The chest support 16 may be detachable and/or modular such that a user may use any one of several chest supports (e.g. one wider and narrower, another with a thicker support pad). The chest support system may further comprise a sensor that measures force or pressure applied, so as to provide a signal to a controller that may adjust the chest support system or provide a warning. For example, if a user is applying too much pressure or force to chest support pad 16, the chest support system may issue, via controller, an alarm such as a visual or audio alert.
Similarly, the head support system (comprising headrest 5 and headrest column 29 as adjusted by headrest radial adjustment 28) is further adjustable in addition to height and radial position. For example, the headrest support system is adjustable in flexibility or stiffness, such that the support (e.g. the column 29) may “give” or flex to varying degrees based on user preference and/or user profile. Also, the headrest 5 may adjust in any of three (3) rotational directions, i.e. in pitch, roll and yaw, either to a fixed angle or an angle that adjusts/adapts once engaged with the head of a user. The headrest 5 may be detachable and/or modular such that a user may use any one of several head supports (e.g. one wider and narrower, another with a thicker support pad). The head support system may further comprise a sensor that measures force or pressure applied, so as to provide a signal to a controller that may adjust the head support system or provide a warning. For example, if a user is applying too much pressure or force to headrest 5, the head support system may issue, via controller, an alarm such as a visual or audio alert.

In one embodiment, said upper body support member further comprising means to position said upper body support to accommodate the chest of a user working in a forward position.
In one embodiment, a seat member means supporting at least a portion of the weight of a user, said seat member means adjustably mounted along the height of said at least one vertical support member to provide for height adjustment to said seating member means, said seat member means further comprising means to position said seat member means to accommodate a sitting user working in a forward direction, said seat member means further comprising of an inflatable bladder to allow the user to move the pelvis freely for comfort, a head support member that attaches to said upper body support that supports the forehead of the user and allows for removability if so desired, a desk surface that accommodates forearm support attaches to said upper body support that slows forearm support for task requiring hand use which is adjustable and removeable.
In one embodiment, the base member is not intended for attachment to the floor of the work space and the work stand may be freely moved and positioned within a work space. In one embodiment, the base member has a sufficient horizontal dimension to provide support and stability and dissipate the forces placed on the work stand by a user. In one embodiment, the horizontal dimension is provided by horizontal load-bearing members attached to said base member.
In one embodiment, the load-bearing members are removably attached for storage or shipment of the work stand. In one embodiment, the base member further includes dowels for the placement of the feet of a user. In one embodiment, the at least one vertical support member comprises a vertical column to which the upper body support member may be attached. In one embodiment, the tubular column is further provided with a extended, slit-like opening therethrough. In one embodiment, the upper body support member is further provided with bolting means employed to attach said upper body support member to said tubular column by the selective positioning of said bolting means through said slit-like opening.
In one embodiment, the bolting means is further provided with radial locking means to permit the radial positioning of said upper body support member. In one embodiment, the seat member means further includes means to position said seat member means to provide support for the legs of a standing user.
The structural materials employed advantageously in the present invention are fashioned from machined plastics, extruded or cast aluminum, although several suitable alternatives are available, as one skilled in the art would recognize readily. Likewise, the padding, where padding is desirable, is preferably some kind of foamed elastomer, and foam rubber has been used to advantage, though other suitable materials exist. Other hardware, brackets, locking pins and supports may be fashioned from aluminum or other suitable material.

For example, in one embodiment, the positioning and/or orientation of one or more components (e.g. the work surface 10) are automatically positioned to a set orientation based on a user profile input by a user. That is, a user may enter a desired work station configuration (perhaps a set height of the modular stool, a set orientation or tilt of the work station mast, and a set orientation of the work surface), and the controller adjusts the work station to the desired configuration. Alternatively or additionally, the controller may access a database of user profiles, and/or set generic user profiles, and adjust the work station to satisfy those profiles. In one embodiment, the user inputs desired work station configuration or settings by way of a display, screen or graphical user interface.
In one embodiment, the adjustment of one or more elements are facilitated or enabled by electromechanical or other motion-augmented means known to those skilled in the art. For example, the adjustment of the modular stool may be adjusted in height through an electromechanical actuator. In one embodiment, the electromechanical or other motion-augmented means are interconnected and/or in communication with a controller that controls the positioning or movement of the work station element of interest.
