Abstract
An adjustable skate includes a boot, a liner, and a bladder. The boot includes an upper and a sole, the upper having a toe cap and a heel portion. The liner is mounted in the boot and includes a bottom plate slidably mounted on the sole and a toe box on a front end of the bottom plate. A chamber for receiving a foot of a wearer's foot is defined between the toe box of the liner and the heel portion of the boot. The bladder is mounted between the toe box of the liner and the toe cap of the boot. The bladder has a volume that is adjustable through inflation of air into the bladder or discharge of air out of the bladder, thereby moving the liner along a lengthwise direction of the boot.
Description
- 1. Field of the Invention
- The present invention relates to an adjustable skate having a bladder. In particular, the present invention relates to an adjustable skate having a bladder for adjusting a length of a chamber in the boot of the adjustable skate according to different foot lengths of different wearers.
- 2. Description of the Related Art
- Skates, whether with wheels or a blade, are popular among young people. Many skates are adjustable in length and/or width to suit different foot sizes of various wearers. Nevertheless, the adjusting mechanisms of the skates are complicated and thus costly. Further, the adjusting procedures for the adjusting mechanisms are troublesome and time-consuming, as they include detachment of bolts and screws before adjustment as well as reassembling of the bolts and screws after adjustment. It is, therefore, a long and unfulfilled need in a simple adjusting device for the skates without time-consuming procedure for adjustment.
- An object of the present invention is to provide an adjustable skate having a bladder for adjusting a length of a shoe chamber in the boot of the adjustable skate according to different foot lengths of different wearers.
- An adjustable skate in accordance with the present invention includes a boot, a liner, and a bladder. The boot includes an upper and a sole, the upper having a toe cap and a heel portion. The liner is mounted in the boot and includes a bottom plate slidably mounted on the sole and a toe box on a front end of the bottom plate. A chamber for receiving a foot of a wearer's foot is defined between the toe box of the liner and the heel portion of the boot.
- The bladder is mounted between the toe box of the liner and the toe cap of the boot. The bladder has a volume that is adjustable through inflation of air into the bladder or discharge of air out of the bladder, thereby moving the liner along a lengthwise direction of the boot.
- Other objects, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
- FIG. 1 is a perspective view, partly exploded, of an adjustable skate in accordance with the present invention.
- FIG. 2 is a side view, partly sectioned, of the adjustable skate in accordance with the present invention.
- FIG. 3 is a sectional view taken along plane3-3 in FIG. 2.
- FIG. 4 is a view similar to FIG. 2, illustrating inflation of a bladder of the adjustable skate in accordance with the present invention.
- FIG. 5 is a view similar to FIG. 3, illustrating a modified embodiment of the adjustable skate in accordance with the present invention.
- Referring to FIGS. 1 through 3, an adjustable skate in accordance with the present invention generally comprises a
boot 1, aliner 3, and abladder 2. Theboot 1 includes an upper 11 and a sole 12 that are integrally molded from rigid plastics. The upper 11 includes atoe cap 16 and aheel portion 17 between which acompartment 13 is defined. Mounted below the sole 12 is a base 15 to which wheels orrollers 14 are attached. Of course, therollers 14 can be replaced with a blade. - The
liner 3 is made from rigid plastics and includes abottom plate 31 on which a foot of a wearer stands. Theliner 3 further includes atoe box 32 on a front end of thebottom plate 31. Thetoe box 32 is configured approximately the same as thetoe cap 16, and thebottom plate 31 is slightly smaller than the sole 12. Thus, theliner 3 is slidable along a lengthwise direction of theboot 1. Achamber 30 is defined between thetoe box 32 and theheel portion 17 of theboot 1 for receiving a foot of a wearer. - The
bladder 2 is mounted in theboot 1 and located between thetoe cap 16 of theboot 1 and thetoe box 32 of theliner 3. In this embodiment, thebladder 2 includes aninlet 21 with a valve (not labeled) exposed outside theboot 1. Thus, air may be inflated into thebladder 2 or air in thebladder 2 may be discharged via theinlet 21. Thus, the overall volume of thebladder 2 is adjustable. Thebladder 2 can be replaced with other equivalent designs. - In use, as illustrated in FIG. 4, if the wearer feels the
chamber 30 is too large for his or her feet, the wearer may inflate air by anair pump 4 into thebladder 2 via theinlet 21, moving theliner 3 in the lengthwise direction of theboot 1. Thus, the overall length of thechamber 30 receiving the foot of the wear is reduced. On the other hand, if the wearer feels thechamber 30 is too small for his or her feet, air in thebladder 2 may be discharged to a desired extent, and theliner 3 is moved forward to the desired position. The adjusting procedure is significantly simplified when compared with conventional designs. - In addition to the adjustment responsive to the length of the foot of the wearer, the
blade 2 provides a function of absorbing impact, thereby protecting the wearer's foot. - FIG. 5 illustrates a modified embodiment of the invention, wherein the
bladder 2 includes a pushbutton type valve 22 and arelease valve 23 that are well know in the art. The function of thebladder 2 is not adversely affected. - Although the invention has been explained in relation to its preferred embodiments, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the invention as hereinafter claimed.
Claims (3)
1. An adjustable skate comprising:
a boot including an upper and a sole, the upper including a toe cap and a heel portion;
a liner mounted in the boot, the liner including a bottom plate slidably mounted on the sole and a toe box on a front end of the bottom plate, a chamber for receiving a foot of a wearer's foot being defined between the toe box of the liner and the heel portion of the boot; and
a bladder mounted between the toe box of the liner and the toe cap of the boot, the bladder having a volume that is adjustable through inflation of air into the bladder or discharge of air out of the bladder, thereby moving the liner along a lengthwise direction of the boot.
2. The adjustable skate as claimed in claim 1 , wherein the bladder includes an inlet with a valve exposed outside the boot.
3. The adjustable skate as claimed in claim 1 , wherein the liner is made of rigid plastics.
