fig1 illustrates a plan view of an in - line skate 10 with an attached braking system 12 , the present invention . the in - line skate 10 includes a boot 14 with a boot base 116 , and opposing planar members 18 and 20 of fig2 which attach to the base of the boot base 16 through a common connecting member 22 forming a channel . four rollers 24 , 26 , 28 and 30 with axle assemblies 32 , 34 , 36 , and 38 secure the rollers between the opposing planar members 18 and 20 . opposing members 40 and 42 connect to a connector member 44 , which can be an integral assembly . holes in the opposing members 40 and 42 secure to the axle assembly 38 . the bottom of the connector member 44 is referred to as the brake shoe 46 . a resilient , pliable brake pad 48 , such as a soft , pliable rubber or other suitable material for frictional engagement with the surface providing an amount of drag producing a braking action , secures to the brake shoe 46 with appropriate screws 50 and 52 through holes in the brake shoe 46 . the angle of the braking system 12 can be adjusted about the axle assembly 38 . further adjustment can be affected through an optional adjustment t - bar 58 , as now described in detail in this fig ., as well as fig2 . the adjustment t - bar 58 includes a threaded shaft 60 , which engages through a threaded spacer 62 secured to upward flanges 64 and 66 of the connector member 44 in fig2 . opposing flat portions 68 and 70 engage into a slot 72 in the rear of the common connecting member 22 . a round t - bar 74 , as illustrated in dashed lines , connects to the flattened portions of the threaded shaft 60 . adjustment of the threaded shaft 60 is by removing the axle assembly 38 to remove the roller 30 , dropping the t - bar 74 below the slot , turning the threaded member through the threaded spacer either a finite distance either in or out and then reversing the previous steps as recited to reinstall the t - bar into the slot and then axially securing the rear roller . this then adjusts the angle of the brake shoe 46 with respect to the ground surface and adjustably spaces the brake shoe 46 with respect to the ground surface . in the alternative , a turn buckle may be substituted for the threaded shaft 60 for positional adjustment . fig2 illustrates a rear view of the braking system 12 , particularly illustrating the threaded shaft 60 where all numerals correspond to those elements previously described . fig3 illustrates the brake shoe 46 of the braking system 12 in frictional contact with a flat skating surface 45 . all other numerals correspond to those elements previously described . the mode of operation has been described in fig1 for adjusting the angle of the brake shoe with respect to the ground surface . the degree of spacing is determined by one &# 39 ; s own preference . the spacing can also be determined by the thickness of the brake pad . the brake pad can also assume any geometrical shape and is not strictly limited to a rectangular planar member . therefore , an in - line skater may desire to exchange brake pads frequently and often depending upon the surface , the degree of wear , and the degree of desired stopping speed . some materials will adhere to surfaces more readily than other materials . fig4 a first alternative embodiment , illustrates a side view of a brake 100 which includes a u - shaped member 102 and a rubber or like material brake pad 104 secured mutually to each other and to the in - line skate 106 . opposing holes 108 and 110 in the u - shaped member 102 align over an axle 112 of the in - line skate 106 to fix and secure the lower half of the brake 100 to the in - line skate 106 . an upper support member 114 extends upwardly and forwardly from the u - shaped member 102 and aligns in a geometrically configured socket 116 in the heel 118 of the in - line skate 106 . attached to a mid - portion of the upper support member 114 is machine screw fastener 120 with a hole 122 to receive threaded shaft 124 , through which adjustable attachment eye bolt 126 is inserted and secured with nuts 128 and 130 . a shaft pin 136 in hole 138 secures the eye bolt 126 and forms a movable pivot point . a pin 140 through hole 142 forms a fixed pivot point about a flange 144 . the flange 144 and eye bolt 126 position in a channel 146 formed by upwardly extending members 148 and 150 . screws 152 and 154 through holes 156 and 158 secure the brake pad to the base 160 of the member 102 . attached to the bottom of upper support member 114 is a brake pad 104 . the brake pad 104 is connected by means of fixed pivot , which affixes through holes in brake pad 104 and hole in the lower end of upper support member 114 , and by movable pivot which connects through an eye of adjustable attachment eye - bolt 126 and opposing holes in the brake pad 104 . fig5 illustrates a top view of the brake 100 where all numerals correspond to those elements previously described . fig6 illustrates a rear view of the brake 100 where all numerals correspond to those elements previously described . fig7 a second alternative embodiment , illustrates a brake 200 which includes a geometrically configured u - shaped member 202 , also of fig8 and a rubber or like material brake pad 204 secured with screws 206 and 207 , as later described in detail , to each other and to the in - line skate . opposing holes 208 and 210 of fig8 in the u - shaped member 202 align over an axle of the in - line skate to fix and secure the brake 200 to the in - line skate . an adjustable upper support member 214 , like that of fig1 - 3 , extends upwardly and forwardly from the u - shaped member 202 and aligns in the geometrically configured socket below the heel of the in - line skate . the adjustable upper support member 214 includes a plurality of teeth 216 on a member 218 for engaging with teeth 220 of the u - shaped member 202 . a bolt 222 engages through an elongated slot 224 of fig8 and into a threaded hole 226 . the dual pivot structure provides that maximum rubber can be located close or adjacent to the ground either in a skating mode or in a braking mode . fig8 illustrates a top view of fig7 where all numerals correspond to those elements previously described . the opposing holes 208 and 210 of the u - shaped member 202 engages over the rear roller of the in - line skate . the round t - bar engages in the heel as previously described in fig1 - 3 . the bolt 222 provides for securing or movement between the teeth 216 and 220 along the length of the elongated slot 224 . fig9 illustrates an end view of fig7 where all numerals correspond to those elements previously described . the brake pad 204 engages into an enclosed area formed by walls 202a and 202b . the brake pad 204 extends over the lower edges 226 and 228 at points 230 and 232 . fig1 illustrates a third alternative embodiment 300 of the braking system 302 affixed about the axial assembly 304 . the braking system 302 includes an integral cast member 306 which engages against the rear edges of the opposing planar channel members 308 and 310 in lieu of the adjustable structures of fig1 - 3 . a brake pad 312 secures with two screws 314 and 316 into holes 318 and 320 into the cast member 306 so that the brake pad is readily interchangeable for either replacement for wear or tear or replacement for other types of braking materials . the operation of the brake system is similar to that as described in fig1 - 3 . the motion from the brake pad is transferred up against the opposing planar members by the contact of the edges of the cast member . fig1 illustrates a fourth alternative embodiment of a brake 400 , including a cast metal brake shoe 402 and a rubber replacement pad 404 , as now described in detail with respect to this figure and the remaining figures . the brake 400 slides into opposing grooves 406 of a brake support 408 , which engages into and about the rear of the in -

an in - line skate braking system for braking of an individual on in - line skates by transferring the center of gravity about the rear roller to frictionally engage a brake pad of one in - line skate or both in - line skates against the ground . the brake pad is of a suitable material , such as rubber , so as to frictionally engage with the ground surface . the degree of braking is determined by the degree of pressure axially transferred about the rear roller by the center of gravity to the brake pad . by the skater properly shifting his or her weight about the rear roller , maximum force can be applied between the brake pad to the ground surface , causing a safe stop over a finite distance . in a fourth embodiment , an after - market replacement brake assembly includes a cast member for engagement with a brake shoe of an in - line skate , and a rubber pad which screws onto the cast member .
