the present invention is a rigid base from which two semi - rigid arms are pivotally attached to unfold from the device and fix firmly at an angle to the base forming a u - shape . the arms have a narrow void at their free ends through which a wide elastomer band is interlaced to span the top of the frame . the ends of the elastomer interlace through the void and back onto themselves such that friction between the ends of the elastomer band holds them firmly in place . pulling on the ends of the elastomer band makes the band tighter and relaxing the interlacing of the band makes the band looser . different interlacing methods of the elastomer band through the narrow voids , allow the elastomer to be more or less firmly fixed to the frame . fig1 . shows an exemplary embodiment of the present invention made of thick wire welded together to form a frame and then plastic - coated . the base is substantially square with two substantially identical inverted u - shaped arms at either end pivotally attached to the cross members by a bent hook configuration . the top ends of each arm have been bent to an angle substantially parallel to the base when the arms are in a fully unfolded position , and a cross member welded to top of the arm to create a narrow void . a wide elastomer band is interlaced first through one void and then the other to both hold the folding frame into the u - shape shown in fig1 . and provide a suitable variable resistance medium with which to exercise . fig2 . shows the side member ( a ) of the base with ends folded to form short curved legs ( b ) on which the frame will sit firmly on both hard and soft horizontal surfaces , such as floors and beds , and vertical surfaces , such as walls and doors . the short legs ( b ) allow the side arms to fold under the base for compact storage and portability . four substantially identical cross members are welded between the two substantially identical side members to form a substantially square base . cross members ( c ) are welded to the superior surface of the side members ( a ) and provide a rigid or semi - rigid limiting stop to the pivoting action of the side arms ( k ) when unfolded from the base . cross members ( d ) are welded to the inferior surface of side members ( a ) and provide a rigid or semi - rigid anchor to the pivoting action of the side arms ( k ) by a bent hook configuration ( e ). an absence of material in the centre of the base ( m ) creates a large void to allow the user increased freedom of movement and greater range of movement within which to exercise the head and neck . two substantially identical side arms ( k ) are shown in a substantially inverted u - shape in fig3 . of an exemplary neck exercise device . thick wire is bent to shape with bent hook configuration ends ( e ) pivotally attached to cross member ( d ) in fig4 . this rudimentary hinge mechanism provides a strong , but lightweight and inexpensive folding method integral to the compact design of the present invention . the side arms ( k ) are of a length shorter than the side members ( a ) to allow them to fold neatly into the base as in fig6 . the top ( f ) of the side arms ( k ) are bent to an angle substantially parallel to the side members ( a ) and cross members ( c and d ), when in the fully unfolded position for the frame as in fig8 . and fig5 . of the present invention . a cross member ( h ) has been welded level with side arm ( k ) and adjacent to cross member ( g ) which is a continuation of the wire bent to form the side arm ( k ). the welding of cross member ( h ) to each side of side arm ( k ), provides further strength and rigidity to the exemplary neck exercise device . the narrow void ( i ) between cross members ( h and g ) can be seen clearly in fig8 . the narrow void ( i ) provides a suitable aperture through which to interlace the wide elastomer band integral to the present invention . the width of the band reciprocates the length of the void ( i ) to provide a stable surface on which to exercise . to complete the exemplary neck exercise device , the elastomer band is threaded through the void ( i ) of one side arm ( k ), typically around cross member ( g ), before spanning the frame and being interlaced around the opposing cross member ( g ) and over the opposing cross member ( h ) as indicated by arrows in fig5 . by angling the top ( f ) of side arm ( k ) substantially parallel to the base of the frame , the interlacing of the elastomer allows enough friction on itself to hold the elastomer firmly in place to exercise , but easily tensioned to increase resistance during exercise . this completes the assembly of the exemplary neck exercise device into the upstanding supporting position shown in fig1 - 3 . loosening of the interlacing to decrease resistance is similarly easy as is removal of the elastomer for folding side arms ( k ) into the base for transport in the collapsed storage position in fig6 . a method of use of the exemplary neck exercise device is illustrated in fig9 . the user places the device on the floor and lies with occipit centred in the elastomer band of the present invention . by drawing the body longitudinally away from the device , friction between the elastomer and the occipit provides gentle traction to the cervical spine for therapeutic effect . a further method of use of the device in this position is to draw the occipit vertically towards the floor against the resistance of the elastomer in a movement commonly called cervical retraction . a user can thus strengthen the cervical musculature that resists the aforementioned problem of forward head posture . in another method , a user can hold the head in the retracted position and further turn the head or tilt the head from side to side against the resistance of the elastomer . the user may perform the same exercises using increasing number , resistance and sustained holds to improve cervical strength further , and perform these exercise in standing and sitting positions with the device against wall or door to improve functionality of the exercise . numerous other materials could equally be found suitable for production of the frame including , but not limited to metal , plastic , timber or a composite material , either moulded , folded or cut from a sheet of material . various materials imbue the frame with either rigid or semi - rigid qualities . the size of the frame and angle of the arms can be varied to allow for different sized occipits and body parts . a bent hook configuration has been used for the hinge - type pivot in afore described embodiment of the present invention , but other embodiments may use hinging mechanisms of different types to allow the frame to fold either in the same or opposite directions . a hinge mechanism may be foregone completely in an embodiment of the device that does not require folding for portability or otherwise . to those skilled in the art , a non - folding embodiment of the frame of the device may take myriad forms . the elastomer band is made of latex , but could also be made of other non - latex elastomer materials or composites thereof . non - latex elastomer materials are particularly suitable for users with latex allergies . the thickness of the elastomer and width of the elastomer can be varied . this allows the user to increase or decrease the resistance of the neck exercise independently of tension , and to allow for different sized heads and other body parts . the device has been designed to exercise the head and neck , but may be used to exercise body parts other than the head and neck . the description of the preferred embodiment of the present invention is presented for the purposes of illustration and it is to be understood that many other possible modifications and variations can be made without departing from the spirit or scope of the present invention . presented uses of the present invention are not intended to be exhaustive or to limit the use of the present invention to the perceived forms disclosed . further applications of the principles of the invention as illustrated therein , various embodiments and various modifications as are suited to the particular use contemplated , would normally occur to those skilled in the art . descriptions of well - known components may have been omitted so as to not necessarily obscure the preferred embodiment of the present invention .
