[0001] The present invention relates to a shoe means.
[0002] U. S. Patent 5,357,695 to the same inventor of this application discloses an interchangeably
assembled shoe including a sole mounted on a foot sporting article such as a roller
skate, plural different instep members (4) detachably secured to the sole, a lining
(5) inserted in the shoe, a plurality of buckle means (7) for fastening the shoe on
a wearer's foot, and the other relevant elements for forming the assembled shoe.
[0003] However, such an assembled shoe has the following drawbacks when trying for multiple
uses:
1. When the shoe provided with the lining (5) and the instep member (4, 4a, 4b) as
shown in Figures 1 - 4 of the U. S. Patent 5,357,695 is removed from a wearer's foot
when not for skating, he or she should wear another shoe for walking or taking a rest,
causing inconvenience for the wearer.
2. Even a wearer's foot already worn with a footwear may still be fitted into the
assembled shoe as shown in Figure 4 of the U. S. Patent 5,357,695 so that he or she
may directly walk by wearing the original footwear (S). However, such a footwear (S)
already worn on a wearer's foot can not be made to be so thick such as lined with
thick foam or cushioning pad in the footwear since the footwear must be inserted into
the narrow toe box member (3) on the sole (1) and will also be limited by the side
flaps (14) provided for fastening the instep member (4c). The footwear (S) as shown
in Figure 4 is so short as lacking of tendon protection and is not suitable to be
a ski boot or snow boot for skiing or walking on the snow area. If trying to wear
a conventional ski boot into the assembled shoe (100), the thick layer of the ski
boot can not be fitted into the toe box member (3) and the side flaps (14) secured
with the instep member (4c) and buckle means (7) of the conventional assembled shoe.
[0004] The present inventor has found the drawbacks of the conventional assembled shoe and
invented the present mother-and-daughter shoe for multiple uses.
[0005] According to the present invention, there is provided a mother and daughter shoe
including: a mother shoe secured on a foot sporting article such as a roller skate
and having a toe box portion and a rear cuff respectively formed on a front and rear
portion of a basic sole of the mother shoe; and a daughter shoe integrally formed
with soft, flexible and shock absorbable elastomeric materials, and snugly engageably
fitted into the mother shoe for manipulating the foot sporting article or detachably
removable from the mother shoe for multiply serving as a ski boot, a snow boot or
a shoe for walking or for climbing a mountain.
[0006] The present invention will be further described with reference to the accompanying
drawings, in which:
Figure 1 is a perspective view of the present invention;
Figure 2 is an illustration showing exploded elements of the present invention;
Figure 3 is a sectional drawing of the daughter shoe of the present invention; and
Figure 4 is an illustration when using the present invention to be a ski device.
[0007] As shown in Figures 1 - 3, a preferred embodiment of the mother-and-daughter shoe
means 100 of the present invention comprises: a mother shoe 1 securable on a foot
sporting article 3 such as a roller skate having wheels 31 with in-line linear arrangement
mounted under a chassis of the roller skate 3; and a daughter shoe 2 snugly engageably
fitted into the mother shoe 1 for playing or manipulating the foot sporting article
3, and detachably removable from the mother shoe 1 for serving a footwear for a ski
boot, a snow boot or any footwear for walking use or for climbing a mountain.
[0008] The foot sporting article 3 may be a roller skate, an ice skate (not shown) or a
ski board 3a as shown in Figure 4, not limited in the present invention.
[0009] The mother shoe 1 for fitting the daughter shoe 2 therein includes: a basic sole
11 secured on the foot sporting article 3, a toe box portion 12 formed on a front
portion of the basic sole 11 having a U shaped notch 121 recessed in the toe box portion
12 from a central portion of the basic sole 11 towards a front end portion of the
basic sole 11 for well inserting a front portion of the daughter shoe 2, a pair of
side edge portions 13 respectively formed on two opposite side portions of the basic
sole 11 having a middle buckle strap 132 secured in at least a middle slot 131 cut
out in each side edge portion 13 for holding a middle portion of the daughter shoe
2, a heel portion 14 formed on a rear portion of the basic sole 11, and a rear cuff
15 pivotally secured to the heel portion 14 by a pivot 141 and having an upper buckle
strap 151 secured on the cuff 15 for fastening an upper portion of the daughter shoe
2.
[0010] The heel portion 14 is formed with at least a rear slot 142 therein for securing
a buckle strap (not shown) for fastening a rear portion of the daughter shoe 2 on
the mother shoe 1.
[0011] Each side edge portion 13 of the mother shoe 1 is recessed concavely between the
toe box portion 12 and the heel portion 14 on the basic sole 11 without forcibly limiting
a side portion of the daughter shoe 2 for a comfortable wearing of the daughter shoe
2 and an ergonomic manipulation of the shoe means 100 of the present invention.
[0012] The pivot 141 for securing the cuff 15 on the heel portion 14 of the shoe 11 may
be formed as a rivet, or a coupling for securing the cuff 15 with the heel portion
14, not limited in the present invention.
[0013] The daughter shoe 2 includes: a sole 21 engageable with the basic sole 11 of the
mother shoe 1, a vamp portion 22 formed on a front portion of the sole 21 to be fitted
into the toe box portion 12 of the mother shoe 1, a boot portion 23 protruding upwardly
from a rear portion of the sole 21 to be generally perpendicular to the sole 21 and
engageable with the rear cuff 15 of the mother shoe 1, a tongue member 24 formed on
a middle portion of the daughter board 2 for protecting an instep portion of a wearer's
foot having a lace 25 secured on the tongue member 24 for fastening the tongue member
24 on the wearer's foot, and a plurality of thermally insulative and cushioning liners
20 made of elastomer foams or the like embedded in the boot portion 23, the sole 21
and in the tongue member 24 for protecting the wearer's tendon, ankle and other foot
portions.
[0014] The outer surface of the daughter shoe 2 may be further finished or covered with
nylon fabric, cloth, or any decorative features or materials. Ventilation devices
may also be provided in the shoe 2.
[0015] The present invention is superior to U. S. Patent 5,357,695 with the following advantages:
1. Once being tired when playing the foot sporting article 3 such as a roller skate,
the daughter shoe 2 may be directly removed from the mother shoe 1 for taking a rest
or for walking for convenient interchangeable uses.
2. The daughter shoe 2 including a boot portion 23 for protecting a wearer's tendon
and ankle portions may be satisfactorily served for a ski boot or snow boot for multiple
uses of the shoe.
[0016] The present invention may be modified without departing from the spirit and scope
of the present invention.
