As a result of this construction, the arm rests are positioned by selectively pivoting the cantilevers about the legs, and the extension arms about the cantilevers.
Description
- This application is a continuation-in-part of application Ser. No. 11/671,217, filed Feb. 5, 2007, which is currently pending. The contents of application Ser. No. 11/671,217 are incorporated herein by reference. Application Ser. No. 11/671,217 claims the benefit of U.S. Provisional Patent Application Ser. No. 60/765,784, filed Feb. 7, 2006.
- The present invention pertains generally to systems and methods for supporting a person on an article of furniture. More particularly, the present invention pertains to a system for accommodating a person lying facedown on a reclined chair. The present invention is particularly, but not exclusively, useful as a system for providing proper anatomical support to a person lying facedown on a reclined chair.
- Adjustable chairs for supporting people in a variety of poses are well known. Specifically, chairs commonly used around pools are adjustable between orientations designed to support people whether seated, or partially or fully reclined. Often, people choose to lie in a prone position on such chairs. However, these chairs are typically uncomfortable for people when lying facedown. Specifically, these chairs require a prone user to turn his/her head to a side. Further, these chairs often flex toward the center of the person, causing uncomfortable pressure on the person.
- Moreover, a person lying prone on a reclined chair typically cannot perform activities such as reading or writing since his/her arms are constrained to his/her side. To turn a page in a book or to use a writing instrument, the person must slide his/her shoulder to the edge of the chair and hang his/her arm below himself/herself to perform the task. While this may be acceptable for an infrequent action, it typically makes reading or writing while in a comfortable prone position impossible. Further, it causes stress on the person's head and spine.
- In light of the above, it is an object of the present invention to provide a system for anatomically accommodating a person lying prone on a reclined chair. It is another object of the present invention to provide a system for supporting the arms of a prone person. It is yet another object of the present invention to provide a system for supporting the head of a prone person. Still another object of the present invention is to provide a system that allows selection of the position and orientation of arm rests and a head support for a prone person. Yet another object of the present invention is to provide a system for providing anatomical support to a person which is easy to use, relatively simple to implement, and comparatively cost effective.
- The present invention is directed to a system for anatomically accommodating a person while lying facedown on a reclined chair. More specifically, the system is designed to accommodate the position of the person's face and to provide support to the person's arms to give proper anatomical support to the person when resting on the surface of the chair.
- Structurally, the system includes two arm rests that can be placed at a desired spatial relationship to the chair. Specifically, each arm rest is provided with an adjustable mount. For purposes of the present invention, the adjustable mount includes a support member that is fixed to the chair. Further, the mount includes a base clamp that engages the support member, and defines a base axis. Connected to the base clamp is a cantilever that extends to an intermediate clamp that defines an intermediate axis. This intermediate axis is preferably parallel to the base axis. In addition to the support member, base clamp, cantilever and intermediate clamp, the mount includes an extension arm that is fixed to the intermediate clamp. The extension arm terminates at a pivot, such as a ball and socket joint, that defines a pivot point. Moreover, the mount includes a bracket that is connected to the pivot and connects to an arm rest.
- In addition to the arm support, the system also provides for proper anatomical support for the person's head. Specifically, the system includes a collar that is connected to and suspended from the surface of the chair. In order to allow the person to lie facedown on the surface of the chair, the collar provides a void in the surface to accommodate the person's face. Structurally, the collar includes a pair of parallel tracks that are interconnected by cross bars. Further, the system includes a head support that slidingly connects to the tracks to allow the position of the void to be adjusted to the person's anatomy.
- In operation, the person may lie facedown on the reclined chair and slide the head support to a desired position. Thereafter, the person may slide the base clamp along the base axis to a desired height. Further, for each arm rest, the person may rotate the intermediate axis about the base axis, and the pivot point about the intermediate axis to position the pivot point at a desired radially distance and angle from the support member. Also, the person may rotate the arm rest about the pivot point to attain a desired orientation of each arm rest. In this manner, the system provides for proper anatomical support of the person.
- In certain embodiments of the present system, the chair includes a static frame formed from two parallel U-shaped side members.

In this manner, theprop arm 88 provides for the seatedorientation 96 shown inFIG. 4A . Referring now toFIG. 4B , thechair 12 is shown in a fully reclinedorientation 98. In the fully reclinedorientation 98, theseat portion 14 and backportion 18 are substantially parallel and provide a substantiallyplanar surface 26 for a person/user 100 to lie facedown, as shown. - In
FIG. 4B , it can be seen that theprop arm 88 is disengaged from theseat portion 14 of thechair 12 and rests on theground 102. Further, it can be seen that thesystem 10 includes atray 104 that is pivotably connected to theprop arm 88 attray axis 106. As shown in its in-use orientation 108 inFIG. 4B , thetray 104 includes aleg 110 that rests on theground 102 so that thetray 104 is substantially parallel to theground 102. Further, thetray 104 is positioned substantially directly below the void 82 in theback portion 18 of thechair 12. Referring back toFIG. 4A , thetray 104 is shown in its storedorientation 112 in which thetray 104 is frictionally engaged, and substantially coplanar, with theprop arm 88. InFIG. 4A , thetray 104 is also shown (in phantom) in an additional orientation in which thetray 104 is substantially parallel to thesurface 26. For this orientation, the system includes a mechanism for holding thetray 104 in position. When held in position, thetray 104 may be used in lieu of a chair-side table. As further shown inFIG. 4B , thesystem 10 includes a cushion or cushionedpad 114 that can be attached to the head support 84 (shown inFIGS. 1 and 3 ) to receive and support the person'sface 116. It is preferred that thecushion 114 be removable from thehead support 84 to facilitate cleaning and replacement. - In operation, the
system 10 facilitates proper anatomical support of auser 100. Initially, thechair 12 may be in the seatedorientation 96 shown inFIGS. 1 and 4A . In order to allow theuser 100 to lie face down on thechair 12, theprop arm 88 is disengaged from theframe 16 of theseat portion 14 and is pivoted about theprop axis 90 away from theframe 16. Thereafter, theback portion 18 of thechair 12 is pivoted about the recliningaxis 20 until it is substantially coplanar with theseat portion 14 of thechair 12 and thechair 12 is in the fully reclinedorientation 98 shown inFIG. 4B . At that time, theprop arm 88 is allowed to contact theground 102 as shown inFIG. 4B . When thechair 12 is in the fully reclinedorientation 98, thetray 104 may be disengaged from theprop arm 88 and pivoted about thetray axis 106 from the stored orientation 112 (shown inFIG. 4A ) to the in-use orientation 108 (shown inFIG. 4B ) with theleg 110 of thetray 104 resting on theground 102. - After the

As theuser 100 lies down, thehead support 84 can be moved along thetracks collar 68 to allow the person'sface 116 to be properly received within the void 82 in theback portion 18 of thechair 12. - When the
user 100 is lying facedown on thechair 12, eacharm rest 28 may be positioned as desired to provide proper anatomical support to theuser 100. Specifically, for eacharm rest 28, thebase clamp 34 may be loosened and raised or lowered along thebase axis 38 in the direction ofarrows 118. Further, thebase clamp 34 may be rotated about thebase axis 38 in the direction ofarrows 120. After thebase clamp 34 is positioned as desired, it may be tightened and locked in place. Thereafter, theintermediate clamp 48 may be loosened and pivoted about theintermediate axis 50 to position thepivot 60 at a predetermined spatial relationship to the void 82 or user'sface 116, i.e., at a predetermined distance from, and angle to, a component of thechair 12, and auser 100 on the chair. In this manner, a radial distance and angle, designated byline 122, between thebase axis 38 and thepivot point 62 is established, and thepivot point 62 is located at a selected axial relationship to the void 82 or person'sface 116. When the desired spatial relationship is attained, theintermediate clamp 48 is tightened and locked. Finally, the orientation of thearm rest 28 is modified to the user's preference by loosening thepivot 60 and rotating thepivot 60 about thepivot point 62. After the desired orientation of thearm rest 28 is found, thepivot 60 is tightened and locked. The process may then be repeated for the other arm rest 28 so that theuser 100 is given proper anatomical support while lying facedown on thechair 12. - Referring now to
