The present invention generally relates to a face cradle for a massage therapy table. More specifically, the present invention uses elastic woven components to better conform to the unique contours of each client's face as they rest their head while in the face-down position.
Face cradles for a massage therapy table have not always been comfortable for a patient or client, when the patient lies on the massage therapy table with their face resting upon the face cradle. Typically, a face cradle has a rigid C-shaped frame that is uniformly padded with a cotton or synthetic material. This design for a face cradle has an inherent flaw in that the rigid C-shaped frame of the face cradle increases the pressure felt at certain points on the patient's face. Consequently, the uniform padding is not able to form-fit to the patient's face because the C-shaped frame does not allow for much structural flexibility with the face cradle. The anatomy of a person's face is very boney, especially near the sinuses, which are located just under very sparse layers of skin and fascia. As a result, the combination of the non-form-fitting nature of a face cradle and the boney anatomy of a person's face can lead to a lot of discomfort and a lot of readjustment as the patient tries to find a comfortable position to rest their face within the face cradle.
An objective of the present invention is to provide users a face cradle, that is able to form-fit to the unique contours of each patient' s face, as the user suspends their face within the elastic woven components of the present invention. Accordingly, the present invention provides an apparatus comprising a rigid structure that holds a webbed elastic face rest. Preferably, the webbing is shaped similar to that of a vortex or semi-toroid that can stretch, and form fit to a person's head/face with no pressure points. Furthermore, the present invention may exist as a standalone structure, or as a removable attachment to a previously existing structure for attaching to a treatment table.
All illustrations of the drawings are for the purpose of describing selected versions of the present invention and are not intended to limit the scope of the present invention.

The following description is in reference to
According to the preferred embodiment, the first adjustment strap 3 is tethered in between a first end 2a of the arch-shaped webbing 2 and the second U-shaped frame 6. Similarly, the second adjustment strap 4 is tethered in between a second end 2b of the arch-shaped webbing 2 and the second U-shaped frame 6. Preferably, the first adjustment strap 3 and the second adjustment strap 4 are continuous or floating elements of the arch shaped webbing 2, that are not interconnected or webbed. Further, the arch-shaped webbing 2 gets the desired shape and dip for placing the user's face, by providing the right amount of pull or tension, on the first adjustment strap 3 and the second adjustment strap 4, of the arch-shaped webbing 2. Accordingly, the arch-shaped webbing 2 converges towards a center of the first U-shaped frame 5 to form a tensioned webbed surface, so that as the patient suspends their face in the tensioned webbed surface, the peripheral areas of their face comfortably rest onto the arch-shaped webbing 2.
In the preferred embodiment, the arch-shaped webbing 2 comprises a plurality of support straps 8 and a plurality of slots 9, wherein the plurality of slots 9 traverses through the arch-shaped webbing 2. In other words, the arch-shaped webbing 2 is made from the plurality of support straps 8 that are interconnected and arranged in a way to simulate a webbed surface having the plurality of slots 9 or gaps traversing through them.
According to the present invention, the plurality of support straps 8 may have different arrangements to better cater the present invention to the unique features of the patient's head. Preferably, each of the plurality of support straps 8 comprises an even thickness. The preferable method of manufacturing the arch-shaped webbing 2 is to position one support strap onto and along another support strap and then attach the two straps at evenly distributed points along the two straps. Consequently, the arch-shaped webbing 2 has a plurality of C-shaped paths, wherein the C-shaped paths that are closer to the center of the arch-shaped webbing have a sharper curvature than the C-shaped paths that are closer to the first U-shaped frame 5. Further, since the arch-shaped webbing 2 is strung across the rigid frame 1, the rigid frame 1 is able to define the overall shape of the arch-shaped webbing 2.
Continuing with the preferred embodiment of the present invention, the arch-shaped webbing 2 has an elastic property so that each of the plurality of support straps 8 can flex to accommodate the unique contours of one patient's face and can reflex to their original position. Furthermore, the plurality of support straps 8 can then flex again to accommodate the unique contours of another patient's face. According to the preferred embodiment, the first adjustment strap 3 and the second adjustment strap 4 are unwebbed extensions of the same plurality of support straps 8 that make up the arch-shaped webbing 2. As seen in
It is an aim of the present invention to provide a face cradle that fits to the unique contours of the face of any patient. In order to accomplish that, the present invention comprises at least one first adjustable fastener 10a, and at least one second adjustable fastener 10b. The first adjustable fastener 10a and the second adjustable fastener 10b allows the user/patient to adjust the tension on the arch-shaped webbing 2 or the tensioned webbed surface, so as to make the face cradle comfortable for their face or head. Accordingly, the first adjustable fastener 10a is connected in between the first adjustment strap 3 and a second leg 5b of the first U-shaped frame 5, and the second adjustable fastener 10b is connected in between the second adjustment strap 4 and a first leg 5a of the first U-shaped frame 5. This arrangement ensures that the first adjustment strap 3 and the second adjustment strap 4 may be accessed by the user from both sides of the first U-shaped frame 5, in order to adjust the tension on the arch-shaped webbing 2. Further, the positioning of the first adjustable fastener 10a and the second adjustable fastener 10b provides the extra stretch and tension needed to support the whole face region of the user. As seen in
In the preferred embodiment, the present invention comprises at least one first drawstring 11a and at least one second drawstring 11b, wherein the first drawstring 11a is terminally attached to the first adjustment strap 3 and the second drawstring 11b is terminally attached to the second adjustment strap 4. The positioning of the first drawstring 11a and the second drawstring 11b ensure easy access and control of first adjustment strap 3 and the second adjustment strap 4 respectively. The first drawstring 11a and the second drawstring 11b may comprise any material, size and length, as long as they do not hinder the intended purpose of the present invention. Examples of which include, but are not limited to, strings, elastic bands, ropes, or cables. Preferably, the first drawstring 11a is threaded through at least one first tensioning support wherein the at least one first tensioning support is from the plurality of supports 7. Similarly, the second drawstring 11b is threaded through at least one second tensioning support, wherein the at least one second tensioning support is from the plurality of supports 7. This arrangement enables proper securing of the arch-shaped webbing 2 to the rigid structure 1, as well as even distribution of tension on the arch-shaped webbing 2. In case of having a single tension adjusting mechanism, the first drawstring 11a and the second drawstring 11b would be threaded through a tensioning support that is positioned midway or along the center of the U, between the first U-shaped frame 5 and the second U-shaped frame 6 . However, the first tensioning support and the second tensioning support may comprise any rigid feature along the rigid support 1, as long as the intended purpose of the present invention is fulfilled. Once the user reaches the desired level of tension within the arch-shaped webbing 2, the two ends of each of the first drawstring 11a and the second drawstring 11b need to be held in place within the rigid frame 1, either through knots, fasteners, or some other tension-holding means. Accordingly, the first drawstring 11a is operatively coupled to the first adjustable fastener 10a, wherein applying force to the first drawstring 11a causes the first adjustable fastener 10a to adjust tension in the arch-shaped webbing 2. Thus, the first drawstring 11a enables the user to adjust the tension of the arch-shaped webbing 2 from the second leg 5b of the first U-shaped frame 5. Similarly, the second drawstring 11b is operatively coupled to the second adjustable fastener 10b, wherein applying force to the second drawstring 11b causes the second adjustable fastener 10b to adjust tension in the arch-shaped webbing 2. Thus, the second drawstring 11b provides easy access for the user to adjust the tension of the arch-shaped webbing 2 from the first leg 5a of the first adjustable fastener 5. According to the preferred embodiment, at least one third drawstring is terminally attached to an apex region 2c of the arch-shaped webbing. Preferably, the third drawstring 11c is threaded through at least one third tensioning support, wherein the at least one third tensioning support is from the plurality of supports 7. In other words, the third drawstring 11c comprises one or more independent straps that are tethered to the rigid frame 1, as well as the apex region 2c of the arch-shaped webbing 2. This is so that the webbing along the sharpest curvature region is separated and the pull reduces the tension on the forehead region of the user. As seen in
Continuing with the preferred embodiment, the present invention further comprises a first plurality of mounting holes 14 and a second plurality of mounting holes 15. The first plurality of mounting holes 14 and the second plurality of mounting holes 15 may comprise, any size, shape and orientation, as long as the intended purpose of the present invention is not altered. Preferably, the first plurality of mounting holes 14 traverses into the first U-shaped frame 5, and the second plurality of mounting holes 15 traverses into the second U-shaped frame 6, such that they act as attachment points for the plurality of supports 7. Accordingly, each of the plurality of supports 7 is engaged into at least one corresponding first mounting hole from the plurality of first mounting holes 14, and each of the plurality of supports 7 is engaged into at least one corresponding second mounting hole from the plurality of second mounting holes 15.
According to the preferred embodiment, the present invention is a retrofit device for the massage therapy table, wherein the elastic face cradle may be manually attached to the massage therapy table. In order to accomplish that, the present invention further comprises a support platform 16, a support assembly 17, a first rod 18, a second rod 19, and a crossbar 20. Preferably, the support platform 16 is connected adjacent to the second U-shaped frame 6, opposite to the plurality of supports 7. This is because, the patient's face must travel through the first U-shaped frame 5 before resting upon the arch-shaped webbing 2, and hence all mechanical support and mounting elements are placed on the lower surface of the second U-shaped frame 6. Preferably, the support platform 16 is screwed to the second U-shaped frame 6. However, any other fastening mechanism that is known to one of ordinary skill in the art may be employed for fastening the support platform 16 to the rigid frame 1. As seen in
It is an aim of the present invention to allow users to adjust the position of the elastic face cradle in multiple directions. Those directions include, but are not limited to, an up and down adjustment and/or a forward/rearward adjustment. In order to accomplish that, the present invention further comprises at least one angle-adjustment bar 21, wherein the user may maneuver the angle adjustment bar 21 to actuate and stop positional displacements. Further, the support assembly 17 comprises at least one adjustable support linkage 22, and the adjustable support linkage 22 comprises a first linkage rod 23, a second linkage rod 24, a first linkage mount 25, and a second linkage mount 26. Preferably, the first linkage mount 25 is rotatably connected in between the support platform 16 and the first linkage rod 23, such that angular displacement between the first linkage mount 25 and the first linkage rod 23 enables the support frame 16 to move forward, rearward, upward, downward etc. Further, the crossbar 20 is rotatably connected to the first linkage rod 23, wherein the crossbar 20 is positioned offset from the first linkage mount 25 across the first linkage rod 23. This arrangement with the crossbar 20 ensures a stable connection of the support frame 16 with the massage table. Similar to the above described arrangement, the second linkage mount 26 is rotatably connected in between the support platform 16 and the second linkage rod 24. Further, the second linkage mount 26 is positioned offset from the first linkage mount 25, across the support platform 16. Furthermore, the crossbar 20 is rotatably connected to the second linkage rod 24, and the crossbar 20 is positioned offset from the second linkage mount 26 across the second linkage rod 24. The above arrangements ensure mechanical and operational stability to the various components of the adjustable support linkage 22, and the crossbar 20. Furthermore, the one angle adjustment bar 21 is operatively coupled to the crossbar 20, wherein rotating the angle adjustment bar 21 between a locked position and an unlocked position enables the adjustable support linkage 22 to modify a distance between the support platform 16, the first rod 18, and the second rod 19. In other words, the various components, relations, and arrangement of the components of the adjustable support linkage 22 and the angle adjustment bar 21, enables smooth positional displacement of the elastic face cradle with respect to the massage table.

In a first alternate embodiment, the present invention comprises a tension directing device 27, which may be used as a junction to redirect the tension applied to the arch-shaped webbing 2. Preferably, at least one tension directing slot (27d and 27e) traverses through the tension directing device 27, and the tension directing device 27 is positioned in between terminal ends of the second U-shaped frame 6. Further, the at least one tension directing slot (27e and 27e) traverses through the tension directing device. Furthermore, the first adjustment strap 3 and the second adjustment strap 4 are threaded through the at least one tension directing slot (27d and 27e). This is so that applying force to the tension directing device 27 adjusts the tension in the arch-shaped webbing 2. As seen in
According to the present invention, the arch-shaped webbing 2 may comprise multiple arrangements of the plurality of straps 8. In a second alternate embodiment, the plurality of slots 9 for the arch-shaped webbing 2 allows a plurality of drawstrings to be interwoven into the arch-shaped webbing 2, such that the arch-shaped webbing 2 is connected in between the Intermediary leg of the first U-shaped frame 5 and the Intermediary leg of the second U-shaped frame 6. This embodiment may further comprise a tension directing device 27 of any shape and operate as described in the first alternate embodiment.
In a third alternative embodiment, a method of manufacturing the arch-shaped webbing 2 comprises the following steps. Attach an end of a double-length strap to the second U-shaped frame 6, then wrap the double-length strap about the first U-shaped frame 5, and finally attach the other end of the double-length strap to the second U-shaped frame 5. Another similar method of manufacturing a webbed surface, is to attach an end of a double-length strap to the first U-shaped frame 5, then wrap the double-length strap about the second U-shaped frame 6, and finally attach the other end of the double-length strap to the first U-shaped frame 5. For both alternative methods, the plurality of slots 9 is created along the double-length strap by attaching the two folded portions at evenly distributed points along the folded-over, double-length strap.
A fourth alternative method of manufacturing each of the plurality of support straps 8 with the plurality of slots 9, is to respectively attach the opposing ends of a single support strap to the first U-shaped frame 5 and the second U-shaped frame 6, and to attach a plastic guide along the single strap, wherein the plastic guide is used as the plurality of slots 9. This method of manufacturing costs less than using two straps, and, as an added benefit, the plastic guide allows the plurality of drawstrings to experience less friction while the webbing is being tensioned. Moreover, each of the plurality of drawstrings is positioned through a designated path from the plurality of C-shaped paths. Thus, the user can pull or release the two ends for each of the plurality of drawstrings in order to increase or decrease the tension within the arch-shaped webbing 2.
A fifth alternate embodiment of the present invention comprises an arrangement, wherein the plurality of support straps 8 do not intersect with each other. This arrangement occurs when the first end for each of the plurality of support straps is fixed to a radial position about the Intermediary leg of the first U-shaped frame 5 and when the second end for each of the plurality of support straps is fixed to the same radial position about the Intermediary leg of the second U-shaped frame 6. This arrangement allows each of the plurality of support straps 8 to remain coincident across one vertical plane.
A sixth alternate embodiment of the present invention may be a case where the plurality of support straps 8 do intersect with each other. This arrangement occurs when the first end for each of the plurality of support straps 8 is fixed to a radial position about the Intermediary leg of the first U-shaped frame 5 and when the second end for each of the plurality of support straps is fixed to an offset radial position about the Intermediary leg of the second U-shaped frame 6. This arrangement allows each of the plurality of support straps 8 to have either a clockwise slant or a counterclockwise slant, which depends on the angular direction for the offset radial position of the second end. The set of support straps 8 with the forward slant is interwoven with the set of support straps with the backward slant in order to create a more complex arch-shaped webbing, but which is able to support more weight. Consequently, the plurality of drawstrings needs to be more intricately woven through the arch-shaped webbing than the aforementioned method with the plurality of C-shaped paths.
In a seventh alternate embodiment of the present invention, the first rod 18 and the second rod 19 are built-in components of a massage therapy table, wherein the first rod 18 and the second rod 19 are already fixed to the massage therapy table.
An eighth alternate embodiment of the present invention could optionally include any of the following ancillary features to improve the functionality of the present invention. One optional ancillary feature is to integrate guides for each of the plurality of support straps 8 into the first U-shaped frame 5 and/or the second U-shaped frame 6, so that the present invention is able to maintain the even distribution of the plurality of support straps 8 about the arch-shaped webbing 2. These guides could be, but are not limited to, grooves embedded into the first U-shaped frame 5 and/or the second U-shaped frame 6 or protruding brackets. Another optional ancillary feature is to integrate another tensioning mechanism between the rigid frame 1 and the plurality of support straps 8 so that the plurality of support straps 8 can be separately tensioned from one or more of the plurality of drawstrings. The aforementioned guides could be used to direct how the tensioning mechanism tightens or loosens the plurality of support straps 8.
As a ninth alternate embodiment, the present invention comprises a basic frame (comprising two identical c-shaped frames that are vertically offset from one another) which will house the structure of the torus shaped elastic webbing. In this embodiment, the torus shape of the elastic webbing is achieved by a combination of vertical strips of elastic attached at points along the top rim of the c-shaped frame structure, rounding in and down and around in a c-shape and attaching at corresponding points on the bottom plane c-shape frame structure, said vertical strips having slots formed by sewing two strips of elastic together, or another method such as guides, which are used to house and offer a path. A method of tensioning said strips into the toroidal/vortex shape comprises having strips of elastic running horizontally, or perpendicular to the vertical strips, through said slots and attaching to a tensioned yet flexible and removable structure spanning the distance of the ends of the c-shaped structure of the frame. The tensioning of these horizontal plane elastic strips and having them attached to said flexible spanning elastic structure at calculated points will give the invention its toroidal form and structure. Part of the design of this removable structure for attachment of the horizontal strips will include the ability to easily change the tension of the strips for variations in the weight or shape of a client's head via some mechanism, either by simple hook and loop fasteners or a more complex ratcheting tensioner. The particular design of the webbing can have a few different manifestations and possibilities for different productions. Using this webbed system of elastic should form fit to every angle, structural shape and form of someone's face and head and have more of an inward pressure/supported wedging principal involved than the typical face rest where direct frontal pressure is exerted of the persons face. Further, there is also the possibility of using a non-elastic quality material for one or both of the horizontal and/or vertical strap bodies instead of elastic. The ability of this material to exhibit similar characteristics to elastic would be achieved by attaching small springs to the attachment points of the material to the frame and/or the tensioning mechanism. Also using one big spring-loaded mechanism that all straps would be attached to instead of individual springs. This may offer cost savings, durability and longevity of materials or manufacturability advantages over elastic. Furthermore, in this embodiment, there is a possibility of needing a small yet rigid u-shaped ring with eyelets that the horizontal straps would go through to offer a small amount of additional customizability to the tension of the face rest.
A tenth alternate embodiment comprises the possibility of not needing a second U-shaped frame 6 at all. The first U-shaped frame 5 housing the elastic webbing may be able to be attached directly to the support mechanism (support platform in the preferred embodiment) that offers the adjustment and attaches it to the table. The guide slot for tensioning the plurality of support straps 8 could also be attached to this mechanism. However, this arrangement would modify the shape of the vortex/torus webbing beyond what is created naturally by evenly tensioning the horizontal straps to allow more room for the eyes, eyebrows, cheeks, etc. by adding additional tension to key vertical straps.
In an eleventh alternate embodiment, no tensioning mechanism is necessary for the optimal operation of the invention. This would be possible by using elastic that has a much lower stretch capacity than typical clothing-oriented elastic.
In a twelfth alternate embodiment, a thin pad, most likely memory foam may be included in the design, located on top of the woven elastic structure. The whole idea of zero pressure points through the use of the woven elastic structure is still entirely valid, but the tensioned elastic itself is possibly a bit rigid to be touching the face directly. This pad may additionally be cast or molded to the specific contours of the average person's face with support or inclusions for certain areas, including but not limited to more support for the chin and inclusions for the eye and sinus areas.
In a thirteenth alternate embodiment of the present invention, the arch-shaped webbing 2 is shaped to provide an even surface for the patient to lie their face. In order to accomplish that, the width of the arch-shaped webbing 2 decreases as it traverses from the first U-shaped frame 5 towards the center of the second U-shaped frame 6. Because the arch-shaped webbing 2 varies its width, crowding of the plurality of support straps 8 is ultimately reduced, which allows more support straps to be used if desired.
Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
