Adjustment means are provided on the boot for adjusting its length. The adjustment means comprises a first, resilient, adjustment member 81 in the front sole section 7. The adjustment member 81 is more particularly located in a cutout 82 formed in the depression 19. The cutout 82 extends inwardly from the rear edge 21 of the front sole section 7 and downwardly from the top surface 27 of the depression 19. The first adjustment member 81 has a series of longitudinally spaced apart stops 83 as shown in Fig. 6. The adjustment member 81 can be formed from a piece of springy wire 85 that is bent to form an end loop 87 at one end with two parallel arms 89, 91 extending from the end loop 87. The arms 89, 91 are relatively close together and the end of each arm is also formed into a closed loop 93, 95 respectively. Each arm 89, 91 is undulated in shape to form adjacent peaks 97 and valleys 99. The adjacent peaks 97 form the stops 83. The adjustment member 81 is fixed in place in the cutout 82 with a screw 101 threaded through the end loop 87 into the front sole section 7, with the member 81 resting on the floor 103 of the cutout 82 and the arms 89, 91 of the member 81 close to the sides 105 of the cutout 82.
The adjustment means also includes a second adjustment member 111 on the rear boot part 11 that cooperates with the first adjustment member 81. The second adjustment member 111 comprises a block 113 fastened to the bottom 39 of the rear sole section 15 and extending forwardly from its rear edge 115. The block 113 is sized to slide snugly into the cutout 83. The bottom surface 117 of the block has a slot 119 formed in it to receive the first adjustment member 81. The sides 121, 123 of the slot 119 are scalloped forming a series of longitudinally spaced apart abutments 125. While a series of abutments 125 have been shown, only one abutment 125, at the front, can be used.
5.
The arms 89, 91 of the adjustment member 81 are resilient and the arms 89, 91 are moved together, using a tool (not shown) that engages the loops 93, 95 on the ends of the arms 89, 91, when the rear boot section is to be mounted on the front boot section. This allows the block 113 to slide into the cutout 82 as the rear sole section 15 is being slid into the front sole section 7. Once the sole sections 7, 15 are at the proper position to give the desired boot size, the arms 89, 91 are released to allow the stops 83 on the arms to fit between the abutments 125 on the block 113 to lock the boot parts in the desired position.
The size of the boot can be easily changed by moving the arms 89, 91 of the first adjustment member 81 together to unlock the boot parts 3, 11 and sliding the rear boot part 11 relative to the front boot part 3 to give a new boot size. Once the new boot size is obtained, the arms 89, 91 are released to have the stops 83 and abutments 125 interlock at a new position. The adjustment means described provides for several incremental changes in the length of the boot. While the adjustment means has been described with the cutout 82 on the top of the front sole section 7 and the block 113 on the bottom of the rear sole section 13, the cutout 82 and the block 113 could be reversed on the sections with the cutout on the bottom of the rear sole section and the block on the top of the front sole section.
Other adjustment means can be employed. For example as shown in Figs. 7 and 8, another form of adjustment means can comprise a rack 131 mounted on the bottom 39' of the rear sole section 13', the rack 131 centered on the rear sole portion and extending longitudinally. A longitudinal groove 133 is formed in the depression 19' on the front sole section 7', extending inwardly from the rear end 21' of the front sole section, to receive the rack 131. A pinion 135 is located in a cutout 137 formed in the bottom 139 of the groove 133. A shaft 141 is passed through a bore 143 in the front sole section 7' which bore intersects the cutout 6.
8 ~ 6 -137. The shaft 141 passes through the pinion 135, with suitable means (not shown) to non-rotatably mount the pinion on the shaft.
One end 145 of the shaft 141 could project out of the bore 143 and be provided with splines 147. A wrench 149 with a splined socket 151 can be used on the end of the shaft 141 to rotate it and the attached pinion 135.
When the rear boot part is mounted on the front boot part, some of the teeth 155 on the rack 131 will engage the pinion 135.
To adjust the length of the boot, all that is needed is to rotate the shaft 141 to have the rotating pinion 135 move the rear boot part 11' relative to the front boot part 3' by way of the rack 131.
The arms 89, 91 of the adjustment member 81 are resilient and the arms 89, 91 are moved together, using a tool (not shown) that engages the loops 93, 95 on the ends of the arms 89, 91, when the rear boot section is to be mounted on the front boot section. This allows the block 113 to slide into the cutout 82 as the rear sole section 15 is being slid into the front sole section 7. Once the sole sections 7, 15 are at the proper position to give the desired boot size, the arms 89, 91 are released to allow the stops 83 on the arms to fit between the abutments 125 on the block 113 to lock the boot parts in the desired position.
