referring to fig1 a plan view of one embodiment of the present invention is depicted . a completed embodiment of a belt load distribution device 1 is shown , lain flat on its internal surface , so that its external surface 2 is visible . the belt load distribution device 1 has a right strap 3 and a left strap 4 . the right strap 3 has a fixed right end 7 , attached to the right edge 8 of the lower back panel 6 of the device 1 , and a free right end 9 . the left strap 4 has a fixed left end 10 , attached to the left edge 11 of the lower back panel 6 , and a free left end 12 . when right strap 3 and left strap 4 are attached to one another , e . g . using velcro 5 or other appropriate means of attachment , they form a belt which helps position and secure the device 1 about the waist of a user . when the device 1 is in use , the lower back panel 6 of the device 1 lays against the lower back of the user , with the internal surface of the device ( not visible in this view ) in contact with the user &# 39 ; s lower back . the lower back panel 6 , and its accompanying components , provides an effective means for distributing a belt load , and the straps ( right strap 3 and left strap 4 ) combine to form a belt which provides a means for positioning and securing the device . the lower back panel 6 is surrounded by its upper edge 12 , right edge 8 , lower edge 13 , and left edge 11 . the lower back panel 6 is fabricated from a lightweight , flexible , launderable , and comfortable material like cotton canvas . other similar materials , such as cotton , linen , flannel , and denim are appropriate and suitable for fabricating the lower back panel 6 . the lower back panel 6 also has a right stay pocket 14 and a left stay pocket 15 , inside each of which is housed a substantially rigid vertical stay . near the upper edge 12 of the lower back panel 6 , and preferably between the vertical stay pockets is an upper horizontal stay 16 . near the lower edge 13 of the lower back panel 6 , and preferably between the vertical stay pockets is a lower horizontal stay 17 . when the belt load distribution device 1 is in position for use on a user &# 39 ; s lower back , the vertical stays cause a belt load , such as the load caused by wearing a heavy gun belt , to be directed away from the spine and distributed over the muscles of the user &# 39 ; s back , thereby preventing chronic lower back pain . the horizontal stays maintain the shape of the lower back panel 6 , preventing creasing and maintaining an appropriate distance between vertical stays ( approximately four inches ). the preferable overall dimensions of the belt load distribution device are approximately nine inches from upper edge 12 to lower edge 13 , and approximately twelve inches from left edge 11 to right edge 8 . right strap 3 and left strap 4 are each preferably approximately twenty - two inches long , although strap dimensions may vary significantly . right strap 3 and left strap 4 may be made from a material similar to that of lower back panel 6 , but are preferably elastic , enabling the device to comfortably fit the waistlines of a broad variety of users . means for attachment of right strap 3 to left strap 4 is provided . although many methods of attachment are appropriate ( e . g . belt buckles , tie loops , clasps , etc . ), velcro is preferred for this embodiment . one surface of the right strap 3 is equipped with one velcro component ( e . g . the hook side ), and the overlapping , mating surface of the left strap 4 is equipped with the other velcro component , such that the two straps can be joined as a belt . in order to fabricate an embodiment of the present invention , one begins with a substantially rectangular pattern of double - ply canvas fabric , approximately sixteen inches across by approximately nine inches . the pattern is placed horizontally , so that the longer dimension is in a left - to - right orientation . an approximate centerline is marked , about which approximately eight inches of material lies to the left and the same amount lies to the right . at approximately three inches from the centerline on both the right and left sides , a substantially vertical fold is made ( folding the outward ends of the pattern inwardly toward the centerline ). one - inch inward from each fold - line , a substantially vertical stitch is made from top to bottom of the pattern . the resulting flaps are then folded back outwardly , forming the right fixed fold - line 18 and the left fixed fold - line 19 shown in fig1 . right stitch 20 and left stitch 21 are added to produce a partially completed , flat lower back panel 6 with right stay pocket 14 and left stay pocket 15 . one substantially rigid vertical stay is inserted into each stay pocket . each vertical stay is substantially rigid , but preferably has just enough flexibility to allow it to be conformed to a comfortable and effective curvature for its particular user . in the preferred embodiment of the present invention , the vertical stays are flat substantially rectangular aluminum pieces , measuring eight inches long , 0 . 75 ( ¾ ) inches wide , and one - eighth ( ⅛ ) inches thick . an example of an embodiment of one of the vertical stays 30 is illustrated in fig2 . an example of an embodiment of a vertical stay with slight curvature is shown in fig2 a . the corners of the vertical stays 30 are preferably slightly rounded , to improve comfort , and to prevent snagging , thereby increasing the life of the surrounding fabric . after the vertical stays have been inserted , they are secured by stitching the vertical stay pockets ( referring back to fig1 right stay pocket 14 and left stay pocket 15 ) closed on all sides , so that the vertical stays are substantially enclosed within the pockets . still referring to fig1 two cotton covered plastic stays are stitched into the lower back panel 6 to help maintain its shape during use . cotton covered plastic stays are available at typical fabric and sewing supply stores . the upper horizontal stay 16 is stitched into place near the upper edge 12 of the lower back panel 6 , in a substantially horizontal orientation . the lower horizontal stay 17 is stitched into place near the lower edge 13 of the lower back panel 6 , likewise in a substantially horizontal position . to complete fabrication of the lower back panel 6 , the upper edge 12 , right edge 8 , lower edge 13 , and left edge 11 are preferably hemmed . the current embodiment of the present invention has ¼ - inch hems . corners are preferably rounded to improve comfort for the wearer . right strap 3 and left strap 4 are sewn into right edge 8 and left edge 11 , respectively . in the current embodiment , the fixed ends of the elastic straps ( fixed right end 7 and fixed left end 10 ) are inserted between plies of canvas before right edge 8 and left edge 11 are finished with a surger . when the surging is completed the straps are securely attached at each edge . velcro tape is preferably stitched to surfaces of the right strap 3 and left strap 4 in locations that allow comfortable use of the belt load distribution device 1 by a variety of wearers . the current embodiment of the present invention uses strips of velcro ¾ - inches wide by 1½ inches long , spaced at six - inch intervals . the current embodiment accommodates waist sizes from 18 to 90 inches . the belt is worn by fastening the elastic straps in the front only , or the straps can be doubled around the user &# 39 ; s waist . the elastic straps are fastened at multiple intervals if desired , and the free ends of the right and left straps can be tied off if their length is unnecessary . conversely , the device is designed and fabricated so that the strap length fits the user specifically . varieties of strap design , geometry , material selection , and method of attachment are left to the imagination of one practiced in the skill of the art , and should be considered within the scope of the present invention . likewise , material selection and other design aspects of the lower back panel 6 may also vary considerably within the scope of the present invention . it should be noted , however , that significant testing has shown that a separation of approximately four inches between vertical stays in the right stay pocket 14 and the left stay pocket 15 provides maximum benefit to the user . a separation of two inches has been tested and found to be significantly less beneficial . a three - inch separation has been found to perform well , significantly better than the two - inch model . the four - inch model , however , has been shown to provide maximum relief in preventing heavy gun belt loads from applying pressure to the spine , and beneficially distributing such loads over the muscles of the user &# 39 ; s back . additionally , it has been shown that rounded corners on the lower back panel 6 provide more comfortable wear , tending less to fold over or to bunch up while in use , or to catch on clothing worn over or under the device . referring now to fig3 one embodiment of the belt load distribution device 1 is depicted in use by a wearer . the belt load distribution device 1 is worn such that the lower back panel 6 is situated on the lower back of the wearer , with the external surface 2 of the device facing outwardly away from the wearer &# 39 ; s lower back . right strap 3 and left strap 4 wrap around the wearer &# 39 ; s waist to form a belt , positioning and securing the device 1 in place . referring to fig4 an embodiment of the belt load distribution device 1 is depicted in use by a wearer with a gun belt 40 also in place . the gun belt 40 ( or tool belt , or other form of heavy utility belt ) produces a belt load that would ordinarily affect the lower back of its wearer , resulting quite often in chronic back pain , especially after repeated daily wear . due to the presence of the subject invention however , the belt load is applied instead to the lower back panel 6 of the belt load distribution device 1 . as described above , the belt load is channeled away from the spine and distributed over the muscles of the wearer &# 39 ; s back , thereby preventing the onset of lower back pain . in summary , the above description of the present invention represents the invention in its preferred embodiment . it should be understood that changes in the details , materials , and component arrangements can be made by those skilled in the art , within the principle and scope of the invention as expressed in the appended claims . although the invention has been described relative to a preferred embodiment , there are numerous variations and modifications that will be readily apparent to those skilled in the art in view of the above teachings . it is therefore to be understood that within the scope of the appended claims the invention may be practiced other than as specifically described .
a belt load distribution device channels the loads produced by heavy belts , such as gun belts worn by law enforcement officers , away from the user &# 39 ; s spine , and distributes the load comfortably across the muscles of the user &# 39 ; s back . heavy belt loads , which typically cause chronic lower back pain in police officers , are significantly mitigated . the belt load distribution device comprises a lower back panel which houses vertical and horizontal stays , and a belt for securing the device around the waist of the user . in addition to alleviating lower back pain caused by the wearing of heavy belts , the device is light , comfortable , durable , adjustable , and easy to maintain .
