Structures that obscure the visibility of spectators are generally disfavored in a spectator activity. However, a participant in the activity, such as an athlete, may at times desire for a limited period of privacy without leaving the viewable area of the activity. For example, a user may need to urinate, change clothing/equipment, or be examined without the spectators viewing the selected activity. Therefore, a structure that has a low profile when not in use, but that can also provide a desired amount of privacy when in use, is contemplated herein.
Aspects are directed to a collapsible privacy structure that has a low profile when in an un-deployed state to preserve the sight lines of observers. The collapsible privacy structure may then be deployed, causing a canopy structure to extend upwardly forming an internal volume that provides privacy and seclusion to the user of the structure. The internal volume may be used for a bathroom, a shower, a medical evaluation/treatment space, and/or a changing space. Upon the departure of the user from the internal volume, the collapsible privacy structure may return to the low-profile nature provided by the un-deployed state.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.
Illustrative embodiments of the present invention are described in detail below with reference to the attached drawing figures, which are incorporated by reference herein and wherein:
The subject matter of embodiments of the present invention is described with specificity herein to meet statutory requirements. However, the description itself is not intended to limit the scope of this patent. Rather, the inventors have contemplated that the claimed subject matter might also be embodied in other ways, to include different elements or combinations of elements similar to the ones described in this document, in conjunction with other present or future technologies.
Aspects are directed to a collapsible privacy structure that has a low profile when in an un-deployed state to preserve the sight lines of observers. The collapsible privacy structure may then be deployed, causing a canopy structure to extend upwardly forming an internal volume that provides privacy and seclusion to the user of the structure. The internal volume may be used for a bathroom, a shower, a medical evaluation/treatment space, and/or a changing space. Upon the departure of the user from the internal volume, the collapsible privacy structure may return to the low profile nature provided by the un-deployed state.
Accordingly, in one aspect, the present invention provides a collapsible privacy structure comprising a base structure having a front portion and an opposite back portion and a first side and an opposite second side; a canopy support having a first side proximal portion, a second side proximal portion and a distal portion, the canopy support at the first side proximal portion pivotally coupled proximate the first side of the base structure proximate the front portion, the canopy support at the second side proximal portion pivotally coupled proximate the second side of the base structure proximate the front portion; a canopy of flexible material coupled to the base structure proximate the back portion and coupled to the distal portion of the canopy support; and a collection vessel coupled with the base structure between the first side and the second side.
In another aspect, the present invention provides a collapsible privacy structure comprising: a base structure having a front portion and an opposite back portion and a first side and an opposite second side; a canopy support having a first side proximal portion, a second side proximal portion and a distal portion, the canopy support at the first side proximal portion pivotally coupled proximate the first side of the base structure proximate the front portion, the canopy support at the second side proximal portion pivotally coupled proximate the second side of the base structure proximate the front portion; a canopy of flexible material coupled to the base structure proximate the back portion and coupled to the distal portion of the canopy support; and an actuator linkage assembly comprising: an actuator support member having a first portion and a second portion, the actuator support member rigidly coupled with the base structure; an actuator member having a first end and a second end, the actuator member first end pivotally coupled with the actuator support member; a carrier link having a first end and a second end, the carrier link first end pivotally coupled with the actuator support proximate the second portion; and a lift link having a first end and a second end, the carrier link second end pivotally connected with the first end of the lift link and the lift link pivotally coupled with the canopy support between the proximal portion and the distal portion.
Having briefly described an overview of embodiments of the present invention, a more detailed description follows.
Aspects of the present invention are related to a privacy structure that has a low profile when in a collapsed state. Conversely, the privacy structure has a sufficient size to accommodate a standing person in an interior volume when in an erect state. For example, when the privacy structure is not needed to provide seclusion, a canopy structure may be collapsed to provide a minimal obstruction height above the ground on which it is positioned. However, when a user desires to have privacy from outside spectators, the canopy structure moves to form a volume that extends above the ground surface a sufficient height to accommodate the user. It is contemplated that the privacy structure may incorporate a urinal or other waste collection mechanism, a shower, a volume for dressing/undressing, and the like. Further, it is contemplated that the size of the privacy structure may be altered to accommodate multiple people or multiple functions, such as a medical evaluation space.
In a spectator event or other line-of-sight activity, it is generally undesirable to obstruct the view of one or more people (or cameras) at the event. For example, in a sporting event with spectators surrounding a field, pitch, court, or other surface, an object that is positioned between the spectators and the intended to-be-viewed activity may create a conflict.
It is contemplated that during an American football game, a structure big enough to enclose and seclude an athlete on the field when the athlete is in a standing position is undesirable from a spectator's perspective as it is likely to obstruct one or more vantage points. However, during the game, an athlete on the field may need to have a conveniently located privacy structure for a temporary period of time, such as for use of a bathroom, changing of clothing/equipment, and/or medical examination/rehabilitation. As a result of the foregoing, aspects of the present invention contemplate a structure with a minimal vision obstruction profile when in a non-deployed state (e.g., non-erect state), but that can easily convert to a privacy structure in a deployed (e.g., erect) state temporarily to serve a particular function. The structure could then be returned to the non-deployed state when the privacy structure is no longer needed. The ability to go from a low-profile, non-deployed state to a deployed state and back to the low-profile state minimizes the duration of time that the privacy structure may obstruct the view of one or more spectators.
Further, as will be discussed in greater detail hereinafter, the privacy structure may be formed with a deployable canopy serving as one or more walls and/or one or more roof structures. The privacy structure may also include a means of egress and ingress from the formed interior volume of seclusion. The means of entry and departure may be a door, curtain, or other structure that is moveably coupled with the canopy to enhance the provided privacy of the internal volume of the erect privacy structure. In an exemplary aspect, it is contemplated that a framed door structure having a covering material, such as the material forming the canopy, stretched thereover may be integrated into the privacy structure such that when the privacy structure is erect, the framed door is maintainable in a closed, privacy enhancing orientation. A user can easily open or close the framed door as a means of egress and ingress. It is contemplated the one or two doors may be implemented individually or in combination. For example, saloon-style doors having a pivotable connection on opposite sides of the structure may be used in an exemplary aspect.
A further exemplary aspect contemplated in connection with the privacy structure is a waste collection system. For example, a collection vessel may be positioned such that when the canopy is in a deployed state, the collection vessel is positioned in the interior volume of the privacy structure. For example, the collection vessel may be a urinal-type component that is intended to serve as a urine capture chamber effective for directing a stream of urine to a storage vessel, which is connected directly or by a transfer structure, such as a flexible hose. The collection vessel may be formed in a funnel-like shape that concentrates a collection of fluid at an outlet port, which may be coupled with the capture chamber. Further, in view of a desire for the privacy structure to have a low profile as a whole, it is contemplated that the collection vessel may be pivotally coupled with the privacy structure such that when the canopy is in a deployed state the collection vessel is in a prominent position functional for collection of a stream of fluid. However, when the canopy is in a non-deployed state, the collection vessel is in a low-profile state that limits a potential obstruction of sight created by the collection vessel, in an exemplary aspect.
The privacy structure may be transportable by a movement means, such as one or more wheels. In an exemplary aspect, it is contemplated that the privacy structure is outfitted with two or more wheels allowing for the structure, in a non-deployed (or deployed) state, to be moved. For example, it is contemplated that the privacy structure may have axially aligned wheels positioned proximate an end of the privacy structure, such as a back end. The privacy structure may be moved by elevating the non-wheeled end of the privacy structure to transfer a greater load to the wheel that is rotatably coupled with a frame of the privacy structure. In an exemplary aspect, this mechanism of movement is similar in concept to a wheel barrow-type movement. However, it is also contemplated that three or more wheels may be used in a wagon-like movement. Further, it is contemplated that no wheels may be used, but insets, a skid, or other not rotatable mechanism may be used. Further, multidirectional bearings or other mechanical movement mechanisms may be implemented.
The change from an un-deployed state to a deployed state may be accomplished by a number of powered and movement mechanisms. For example, human power may deploy one or more features. An actuator may deploy one or more features. It is contemplated that hydraulic, pneumatic, and/or electric power may be leveraged to cause the deployment or un-deployment of any feature contemplated herein. Regardless of power source, it is contemplated that a mechanical advantage may be gained and a controlled-motion path may be achieved with one or more links in a linkage system. Further, it is contemplated that a linkage system may be implemented to achieve a speed of motion, a limit of movement, a range of movement, and the like. Exemplary linkage systems will be discussed in greater detail hereinafter. It is understood that a linkage system may be used or may be omitted, depending on the aspects contemplated.
Turning to the figures in general and
The base structure 102 has a front portion 104, a back portion 106, a first side 108, and a second side 110. As depicted, the base structure 102 is formed from a frame structure with a polymer-based inlay. In this example, the frame structure may be formed from metallic components that provide a structural support necessary to support the linkage mechanism discussed hereinafter. Further, it is contemplated that the base structure may be formed having a mass of substantial portion to provide a sufficient anchor and low center of balance to resist a tipping force when the collapsible privacy structure 100 is in a deployed state. For example, when the collapsible privacy structure 100 is in a deployed state, a wind-generated force acting on the canopy 300 that initiates a tipping force may be resisted by the base having a structure of sufficient mass.
The collapsible privacy structure 100 may be formed in a pan-like manner such that a pair of vertical sides extend upwardly to form the first side 108 and the second side 110. It is further contemplated that a vertical portion may extend upwardly from the back portion 106.
As a result, it is contemplated that the collapsible privacy structure 100 may be formed having three wall portions extending upwardly from a base portion. It is further contemplated that a front wall proximate the front portion 104 is omitted, in an exemplary aspect. For example, to facilitate easy ingress and egress from the collapsible privacy structure 100 when in a deployed state, the absence of a front wall limits obstacles for the user to enter an interior volume 114 of the deployed collapsible privacy structure 100.
It is contemplated that collapsible privacy structure 100 is comprised of a base plate 112, which forms a portion of a floor-like surface in the base structure 102. The base plate 112 may be pivotally coupled with the base structure 102. The base plate 112 has a front edge, a back edge, a first side edge, and a second side edge. It is contemplated that the pivotal coupling of the base plate 112 allows for the base plate to activate a pressure switch 105 in response to a change in load that occurs when a user prepares to enter the interior volume 114 of the collapsible privacy structure 100. For this reason, it is contemplated that the base plate 112 in connection with the pressure switch 105 acts to activate an actuator and linkage assembly to cause the collapsible privacy structure 100 to change from an un-deployed state to a deployed state. Therefore, it is contemplated that the front edge of the base plate extends outside of the interior volume 114 such that the activation and deployment can occur prior to the user entering a volume that will become the interior volume 114 when deployed.
It is further contemplated that the base plate 112 may be fixedly coupled with the base structure 102 in an exemplary aspect. Further, it is contemplated that any type of activator may be implemented to cause the deployment. For example, a button, a switch, a motion detector, a light-beam continuity switch, and the like. Therefore, it is contemplated that any type of mechanism may be implemented to cause the deployment of the canopy 300 by an actuator (or manual force).
The canopy 300 may be formed from any material, such as a textile, a knit, a woven, a processed polymer, and the like. For example, polyester, nylon, canvas, or other material used in the construction of tent-like structures may be implemented. In an exemplary aspect, it is contemplated that the canopy 300 may be formed from a flexible material that is effective for obscuring visibility into the interior volume 114. The canopy 300 may be of any color, texture, weight, and material.
The canopy 300, in an exemplary aspect, when in a deployed state as depicted in
The canopy support 202 is a support that extends in a rib-like manner from a pivotal connection on a first side of the base support to a pivotal connection on a second side of the base support. The canopy support 202 has a proximal portion 204 proximate the pivotal connection. In some aspects, such as the aspect shown in
While
The door 402 has a top side, a bottom side, a first side, a second side, a front surface, and a back surface. It is contemplated that a gusset is formed between the front surface and the back surface in which a counterweighted, pivotally coupled door rod is moveably mounted. As will be provided hereinafter, the door rod pivots in a generally first side 108 to second side 110 direction when the canopy support 202 is in a near (or fully) deployed state. The movement of the door rod based on an offset counterweight causes a gravity induced closure of the door when the canopy support 202 is in a near vertical position of the deployed state, as will be discussed in greater detail in
A pivotal coupling point off of the base structure 102 for the canopy support 202 at a proximal portion 204 is depicted in view 200. This pivotal connection is a pivot point at which the canopy support 202 articulates to change from a deployed to non-deployed state. The second canopy support 208 is pivotally coupled to the base structure 102 in a similar location; however, it is contemplated that the second canopy support 208 pivotal coupling point is offset by at least a distance of the diameter/thickness of ½ the canopy support 202 and ½ the diameter/thickness of the second canopy support 208, to limit an interference or binding between the canopy support structures during the deployment and un-deployment actions. A similar pivot connection offset location is contemplated for the third canopy support 210. Stated differently, it is contemplated that each of the canopy support members has an offset pivotal connection in the same vertical plane. In an exemplary aspect, the offset different pivotal points is implemented as opposed to having laterally offset members sharing a common pivot point to allow for the linkage assembly, to be discussed hereinafter, to freely interact with the canopy support 202 during a deployment action.
It is contemplated that the canopy 300 is coupled with each of the canopy supports 202, 208, and 210, in an exemplary aspect. Therefore, the canopy 300 serves as a carrier material that when the canopy support 202 pivots from an un-deployed state to a deployed state, a tension force exerted by the canopy 300 onto the canopy support 208 and the canopy support 210 cause each of the canopy supports to also articulate. Stated differently, by pulling a front portion of the canopy by the pivoting of the canopy support 202, the canopy pulls on the remaining canopy supports, which causes each of them to pivotally move in response to the tension force applied by the canopy 300.
Also depicted is a wheel assembly 116 rotatably coupled to the base structure 102 proximate the back portion 106. It is contemplated that an axially aligned wheel assembly may also be rotatably coupled on the opposite side of the collapsible privacy structure 100. The combination of wheel assemblies may work in coordination to allow the collapsible privacy structure 100 to be moved, such as in a wheel-barrel fashion.
The base structure 102 is depicted having the front portion 104 and the back portion 106. Also depicted is the wheel assembly 116. In the un-deployed state, the canopy 300 is folded about itself in an accordion-like fashion with the canopy structures in a substantially horizontal manner and in close proximity to one another relative to when in a deployed state.
Stated differently, distal portions of the various canopy structures are more proximate one another in an un-deployed state than when in a deployed state. Further, when in the un-deployed state, the distal portion 206 is positioned proximate the base structure 102. To achieve an un-deployed state, the canopy structure pivotally articulates about a pivot point proximate the proximal portion 204.
In an exemplary aspect, a user would approach the collapsible privacy structure 100 at the front portion 104 when in an un-deployed state and an actuator and linkage assembly would be activated, such as upon pressure being applied to the base plate 112. The activation of the actuator would cause the canopy support to pivot about a pivot connection which would raise the distal end of the canopy support structure, causing the canopy to also raise and form an internal volume. The formed internal volume may be formed on two sides, a back portion, and an overhead portion (to prevent potential spectators seated above from having visibility to the internal volume) may be formed by the canopy in the deployed state. In order to further enclose the internal volume, the door rod 406 may pivot in a second side 110 to a first side 108 direction.
This medial direction pivot may extend a door portion to form a complete or partial enclosure of the internal volume about an ingress/egress portion of the internal volume.
Also depicted is a collection vessel 502. The collection vessel in this example is a funnel-like structure formed as an inverted pyramid. The collection vessel 502 provides a concentration structure that allows a stream of liquid to be generally provided and then focused into a collection container; much like a typical funnel is intended to function. While the shape of the collection vessel 502 is depicted as an inverted pyramid, it is contemplated that alternative structures may be implemented. For example, a different geometry may be more suited for some users than others. Women, for example, if using the collapsible privacy structure 100 as a bathroom, may desire a different collection vessel 502 than a male may desire. Therefore, it is contemplated that a variety of collection vessels may be used or exchanged to facilitate specific uses and users.
In the un-deployed state (i.e., collapsed state), it is contemplated that a collection vessel, such as the collection vessel 502, is in an un-deployed position that results in a lower profile than when in a deployed position. As depicted, the collection vessel is in a horizontal position in the un-deployed state, but pivots to a vertical position in a deployed state. In alternative aspects, the collection vessel may be fixedly coupled to the base support.
In an exemplary aspect, the collection container 506 is a container for storing and transporting liquid or other contents. For example, a user may urinate into the collection vessel 502, which directs the urine to the transfer hose 508. The urine passes through the transfer hose 508 into the collection container 506. It is contemplated that the collection container 506 is removable, such that when cleaning is to occur or emptying of contents from the container, the collection container may be individually removed from the collapsible privacy structure 100 to allow for easy disposal of the contents. For example, the collection container may be taken to a drain and the contents may be poured out from the collection container. It is contemplated that the transfer hose 508 is flexible in nature allowing for the collection vessel 502 to pivot from a deployed to un-deployed position while maintaining the transfer hose 508 in connection with both the collection vessel 502 and the collection container 506. The collection container may be a 1-10 gallon plastic container suitable for collecting the contents input into the collection vessel 502.
Also depicted, and as will be discussed in
The actuator may use alternating current or direct current. The actuator may use a high voltage (e.g., 110 volts) or lower voltage (e.g., 12 volts). As previously discussed, it is contemplated that in place of or in addition to the actuator, a pneumatic, hydraulic, or other power mechanism may be implemented to automatically deploy the collapsible privacy structure 100.
The actuator 704 has a first end 716 and a second end 718. The first end 716 is pivotally coupled with the linkage support 702 proximate a second end. The second end 718 of the actuator 704 is pivotally coupled with a second end 722 of the carrier link 706 and a first end 724 of the lift link 708. A first end 720 of the carrier link 706 is pivotally coupled with the linkage support 702 proximate a first end 712 of the linkage support 702. A second end 726 of the lift link 708 is coupled with the canopy support 202 at a location between the proximal portion 204 and a distal portion of the canopy support 202. The linkage assembly 700 is depicted in the deployed state.
In an un-deployed state, the actuator 704 second end 718 retracts causing an angle between the lift link 708 and the carrier link 706 to become more acute, which allows (or causes) the canopy support 202 to pivot about a pivotal connection proximate the proximal portion 204.
While a specific linkage configuration is depicted, alternative combinations of links and relative positioning of the links, and sizes of links, may be implemented to achieve a desired degree of movement for a particular amount of actuation force.
Additionally depicted are elements allowing for gravity deployment and mechanical un-deployment of a door portion. For example, the door rod having a counter weight 407 is pivotally coupled at a pivotal connection to the canopy support 202. As will be discussed in
In an exemplary aspect, the door rod relies on gravity to extend from a near vertical position to a medial extending position, which causes a movement of a door portion to which it is moveably coupled. However, upon the transition from a deployed state to an un-deployed state, the retraction cable 802 applies a force to the door rod that causes the door rod to pivot back to a substantially aligned orientation to the canopy support 202. Stated differently, the retraction cable 802 and the tension spring 804 are utilized to overcome the gravitational force that repositioned the door rod from a vertical orientation to the medial orientation. Once overcome, the doors “open” and are pulled out of the way of the collection vessel as the canopy returns to a low-profile position.
Additionally, the door rod 406 is depicted. The linkage assembly is also depicted with the actuator 718, linkage support 702, carrier link 706, and lift link 708. Also depicted are the collection vessel 502 and a collection link 504 that is pivotally coupled with the collection vessel 502 and the third canopy support 210. The collection link 504 causes the rotational position change of the collection vessel 502 when transitioning from an un-deployed to a deployed state.
Also depicted is a collection container 506 that may be moveably secured therein. For example, it is contemplated that the collection container 506 may be removed from the collapsible privacy structure, such as to empty the contents maintained in the collection container. Also depicted is a wheel assembly 116 (1116 in
Components and structures of
The framed door 1402 is a structure having rigidity sufficient to maintain a desired form even when exposed to wind, user interaction during opening and closing, and during deployment and un-deployment state changes of collapsible privacy structure 1100. For example, the framed door 1402 may be comprised of one or more structural elements, such as tubular metal or polymer-based materials. The structural elements may form a door perimeter (e.g., a rectilinear shape) about which a covering material is mounted. For example, a canvas or other sheet-like material may be stretched or otherwise maintained in place and tension to form the corpus of the door. As depicted in
The framed door 1402 may be moveably coupled with other components of the collapsible privacy structure 1100 by way of hinges 1403. In the depicted configuration, the hinges 1403 pivotally hinge the framed door 1402 to a canopy support, such as canopy support 1202. While the hinges 1403 are depicted on the first side 1108, it is contemplated that the hinges or other connections mechanisms may be positioned on the second side 1110, a distal end of the canopy support, a proximal end of the canopy support, or elsewhere. Further, it is contemplated that one or more self-closing mechanisms are also used in connection with the hinges 1403. For example, it is contemplated that a torsion spring, a coal spring, a pneumatic, or the like element is used to suggest a closed state to the framed door 1402, in an exemplary aspect.
The framed door 1402 is contemplated to further include (or other components of the collapsible privacy structure 1100) one or more temporary maintaining components. For example, a maintaining component may include a latch, a magnetic securing component, actuator, pneumatic or mechanical springs, and the like. The maintaining components are effective to maintain the framed door in a closed state when the collapsible privacy structure is in a deployed and/or non-deployed state.
Also depicted in
The collection vessel 1502 is coupled (rotatably coupled in an example) to a collection link 1505. The collection link 1505 is pivotally coupled proximate the back portion 1106 of the base structure 1102 or other components of the collapsible privacy structure 1100. As better depicted in
As depicted in
Regardless of the configuration implemented, it is contemplated that the collapsible privacy structure is functional to transition from a non-deployed state to a deployed state. The deployment may include a user activating a movement mechanism through presence/proximity (e.g., motion detecting switch), through passive action (e.g., activating a switch in a press plate upon entering), and/or through active request (e.g., intentionally engaging a switch-like element). For example, it is contemplated that a user may approach the collapsible privacy structure and place pressure by stepping on a component coupled with a switch. Upon activation of the switch, one or more mechanical elements (e.g., an electric linear actuator) drive one or more linkages (or direct drives to canopy) to cause a deployment of the canopy. The canopy may remain deployed while the user remains present, such as continued sensing by the activation switch, through continued sensing by a secondary mechanism (e.g., a motion detector), and/or through secondary activation of the activating switch at egress (e.g., stepping on the component/switch upon exit). Therefore, it is contemplated that the transition between deployed/non-deployed states may be activated in a number of ways.
Although the collapsible privacy structure construction is described above by referring to particular embodiments, it should be understood that the modifications and variations could be made to the collapsible privacy structure construction described without departing from the intended scope of protection provided by the following claims.
