fig1 is the left - front side perspective view of the sports net rebound apparatus showing the complete a shaped net support frames 10 as freely providing an adjustable angular lean of the net if standing on a ground plane . said frames join and pivot at the top of the net , see fig3 item 23 , for either collapsing for portable storage or standing at an angularly adjustable a shape for usage on a relatively flat surface . said net can be mounted on raised extension legs at a more vertical position or mounted on other platforms for various uses . fig1 reveals the front bumper pad 20 which protects edges of the net that are susceptible to possible damage . the key embodiment in net matrix 11 reveals a diamond shaped cross hatch pattern which seems to work better for capturing and rebounding footballs , or other objects than a ‘ checkered square ’ shaped matrix does . fig2 is a front view of the sports net rebound apparatus showing the net matrix 11 and bumper pad 20 which covers the frame and edge mounting of the net matrix 11 in order to protect said matrix at the weakest points on the edge mounting . also revealed is the anti - skid feet 32 to prevent movement of the bounce back item net . fig2 a is a front view of the bounce back item net without the bumper pad , see fig1 item 20 , illustrating a net corner , symbolic of other corners , which reveals the net matrix 11 mounted to inner frames net support structure 12 which is comprised of corner net mount and brace 29 secured to inner frame mounting bars 24 by small mounting roundhead bolts 27 . said inner frames net support structure 12 is mounted to the outer front net support frame 10 by mounting standoffs 25 , mounting hex - head bolt 26 to net support frame 10 by frame locknut 35 . fig2 a clearly shows the outer front net support frame 10 elements consisting of front vertical frame component 13 attached to the front top horizontal frame component 15 by a frame elbow joint 19 . identical structure exists on other 3 corners . net matrix 11 elements consist of select elastic net cords 21 and net tie point devices 22 which secure cords together at diagonal cross points locking in the cord matrix to prevent passage of an object through the net which allows capturing the angular momentum of a ball or object so that rebound to the sender or where the object came for rebound return . net cord 21 is mounted through net mounting holes 31 in the inner frame mounting bars 24 and corner net mount and brace 29 and is secured in place on each end of net cord 21 using net crimp / holders 30 . fig3 is the left side view of the sports net rebound apparatus which reveals rear vertical frame component 14 , pivot device 23 , front vertical frame component 13 with bumper pad 20 mounted by frame locknuts 35 to said frame . also revealed are mounting hex - head bolts 26 are which secures the inner frame mounting support structure 12 to front vertical outer frame component 13 , as shown in fig2 a . fig4 is the back view of the sports net rebound apparatus showing top pivot devices 23 , net matrix 11 , rear vertical frame component 14 , rear top horizontal frame component 16 , rear bottom frame component 18 , and the back side of bumper pad assembly 20 . not show on back side view . fig5 is the top view of the bounce back item net which clearly shows the bumper pad 20 , net matrix 11 , and top pivot device 23 . fig1 a is the side cutaway view of the bumper pad assembly 20 , shown in fig1 , revealing construction components starting with vinyl tape or covering 37 enclosing said assembly comprised of firm foam padding 39 , bumper mounting base 38 , frame hex head bolt 34 , for mounting to outer front net support frame 10 as shown in fig3 , frame nuts 35 , washer 33 , and lock washer 36 . from the description above , a number of advantages of some embodiments of my bounce back item net become evident : ( a ) both front and back frame net support structures give strength , stamina , and flexibility to either adjust the leaning angle for usage or to flatten for storage . ( b ) the unique anti - skid feet help prevent movement from impact by balls or objects . ( c ) the front bumper pad protects edges of the net matrix from damage extending net life . ( d ) the unique net matrix is diamond shaped for optimal catching of balls , especially footballs . various reticulated designs could be utilized for unique objects . ( e ) the unique net matrix design provides a high energy rebound of the object with little loss because the net absorbs most energy laterally reducing stress and loss of energy to the net frames by captures and holds impact energy efficiently thus limiting loss of energy and allowing optimal rebound of energy , such energy as is trapped in the cords themselves . ( f ) can provide angular rebounds of balls or objects up to sender or from where it came are of up to about 45 degrees to either side from front and center . ( g ) provides very accurate control of where a ball or object is sent . ( h ) provides minimal stress on the net matrix as well as the mounting framework provides longer life of the net , mounting structure , and of the ball or object . this net is specially tailored for the oblong shaped footballs but not limited to oblong shapes etc . this net rebound direction can be controlled by the user - or sender in the vector or direction , where — the object is to be rebounded to . this net will rebound with minimal energy loss , controlled direction , rebounding in a uniform distance , and with an approximately identical force . this should not be limited to footballs or even sports balls but can have applications that go much further . although the description above contains many specificities , these should not be construed as limiting the scope of the embodiments but as merely providing illustrations of some of the several embodiment &# 39 ; s capabilities . as specified , this should not be limited to football or even sports but can have applications that go much further . the net matrix is shown as a diagonal diamond shaped pattern but the principles laid out can be used in different patterns like a square reticulated pattern , etc . the distance between cords and the tension of the cords can be changed for various applications . this structure could be knit , eliminating the need for tying cross points but may not work so efficiently for sports applications , especially footballs , but would probably work in many other applications , especially if coated with an elastic material similar to the modulus of the cords — stabilizing positions to absorb ‘ vector energy ’ and rebound it back where it came from .
this is the embodiment of the net apparatus used in sports and in the non - sports arenas . this net &# 39 ; s frame supports an inner net framed matrix that connects and pivots a rear frame for an adjustable triangular - shaped lean to control the trajectory of the ball or object . the net is designed to rebound balls or objects with high energy even at side angles to return the ball to the sender . the net is also designed to minimize stress to both net and frame when a ball or object contacts the net .
