MODES FOR CARRYING OUT THE INVENTION

A seating part is provided in an upper part of a shoe itself which a person wears and is required for outdoor activities to achieve that the person can easily sit on the shoe anywhere at any time only by squatting down on the shoe.

Embodiment 1

FIGS. 1 to 4 illustrate one embodiment of claim 1 of the present invention and is a so-called boot-shaped shoe (A) such as a boot or a rain boot. The shoe (A) is configured so that the entire shoe (A) is substantially divided in half at the arch of the foot in a front-to-rear direction. A tiptoe part (10) side of the shoe is made of a material such as a soft rubber, and a heel part (9) side and a legging part (8) side above the heel part are made of a hard and strong material. An upper front part extending from an upper part of an instep part (7) to the shin is entirely opened as an opening part (D). Thus, when the person wears the shoe (A) and squats down, his/her leg under the knee freely projects forward from the front-side opening part (D) in the upper part of the boot shape. Therefore, the person can sustain his/her upright posture similar to the standing posture, without dragging the rear part of the boot shape forward together.

In addition, a top part of the hard and strong legging part (8) on the calf side is provided with a seating part (3) so as to project horizontally rearward. Therefore, when the person squats down while wearing the shoe (A), he/she can sit on the seating part (3) as a stool as it is.

Alternatively, when the person performs activities while wearing the shoe (A) in a case where soil or the like may enter into the shoe (A), the person can wear another arbitrary shoe with a low heel and then wear a larger size shoe (A).

Embodiment2

An embodiment of FIG. 5 is a so-called boot-shaped shoe (A) such as a boot or a rain boot according to claim 2. The entire front side of an upper part where a leg part from an instep part (7) to the shin contacts is opened as an opening part (D). A rear part where a heel part (9) and the calf in the lower leg rear part contact is made of a hard and strong material, and a top part is provided with a seating part (3) projecting horizontally rearward, to form the shoe (A) which can also be used as a stool. Inside the hard upper part of the shoe, a substantially cylindrical tube made of a soft material similar to that of a cylindrical upper part of a rubber rain boot is provided so that it continues from a lower circular part for inserting a foot which opens around the ankle. The lower circular part continues from the tiptoe side, inside of the rear part, of the boot-shaped shoe (A) made of the hard and strong material, and is fluid-tightly formed with the substantially cylindrical tube. Thus, the soft tube for inserting the leg is additionally provided as a shank part (15) inside the upper part of the shoe (A) to have a double structure in which the boot-shaped part having a hard seating part (3) is disposed outwardly and rearwardly. Therefore, it has a waterproof function similar to rain boots.

Embodiment 3

An embodiment of FIG. 6 is a so-called boot-shaped shoe (A) such as a boot or a rain boot according to claim 3. The entire front side of an upper part of the shoe where a part extending from the instep part (7) to the shin contacts is opened as an opening part (D). A rear part where the heel part (9) and the calf in the lower leg rear part contact is made of a hard and strong material. The shoe (A) can also be used as a stool, which is provided with a seating part (3) projecting horizontally rearward in a top part thereof. An integral rear overlapping part (20) is formed by a thin plate made of a lightweight and strong material such as an aluminum alloy, which can cover from the rear part of the shoe (A) from a sole part (11) below the heel part (9) in the rear part of the shoe (A) to the seating part (3) in the upper part of the shoe (A) so that it conforms to the shape of the shoe part. The rear overlapping part (20) is integrally provided to the shoe so that it horizontally slides rearward in a front-to-rear direction. Particularly, the upper part of the rear overlapping part (20) has the same shape as the seating part (3) located in the top part of the shoe (A) and covers the seating part (3) from the rear. Thus, when the rear overlapping part (20) is pulled rearward to slide, since the top part of the rear overlapping part (20) also functions as a second seating part (21) continuing from the seating part (3), a wider seating surface can be obtained.

FIGS. 7 to 11 illustrate an embodiment of claim 4, and is a so-called boot-shaped shoe (A) such as a boot or a rain boot, and the shoe (A) includes a heel part (9) in a rear part of the shoe (A). A rear part of the shoe (A) on the calf side above the heel part (9) is made of a hard and strong material, and the shoe (A) can also be used as a stool, provided with a seating part (3) projecting horizontally rearward in a top part of the shoe (A). An edge surrounding part (31) is provided in the circumference of a lower part of the shoe (A) where a part of the foot from the heel to the sides of the tiptoe and the like contacts, and the edge surrounding part (31) is formed of a plate member made of resin or the like which is hard yet has some flexibility. A tiptoe side of the edge surrounding part (31) is formed with a tiptoe-side opening part (F) which is a notch in the surrounding part. In addition, a sole part (11) of the shoe is provided with nothing except for a tiptoe-side sole rubber part (36) near the toe root part, and a heel-side sole rubber part (35). A part of the shoe (A) where the shin contacts, from a front side of the shank part (15) to an upper part of the instep and tiptoe side is entirely opened, and the sole part of the shoe is penetrated therethrough in the vertical direction.

In addition, the edge surrounding part (31) is also provided with a rubber belt (37) which is a fastener serving as a shoelace, and latch parts (39) on both the outside side faces where the ends of the rubber belt (37) are hooked and locked. Then, after inserting to fit another arbitrary shoe (G) having a sole into the shoe (A) described above from the top or bottom of the shoe (A), the rubber belt (37) provided to the edge surrounding part (31) on the side faces of the instep is placed from above and latched so that the person can wear the shoe (G) integrally with the shoe (A). In addition, if the size of the another arbitrary shoe (G) to be inserted is somewhat large, it can be inserted while expanding the tiptoe-side opening part (F) of the shoe (A) outwardly. The another arbitrary shoe (G) can be freely pulled out to separate from the shoe (A) by removing the rubber belt (37) as the fastener.

The tiptoe-side sole rubber part (36) is slightly provided near the toe root part because of the following reasons: by stepping to press down the tiptoe-side sole rubber part (36) by the tiptoe side of the another arbitrary shoe (G), the rubber belt (37) which contacts the upper side of the instep part of the another arbitrary shoe (G) becomes a fulcrum to raise the heel side of the shoe (A) without falling so that the person can walk easily; and when the person sits on the seating part (3), the front side of the shoe (A) will not be raised to incline. Note that the tiptoe-side sole rubber part (36) which is slightly provided near the toe root part may be replaced with a string, such as a wire, in order to acquire the same effects.

Further, the projecting direction to the rear of the seating part (3) provided in the rear top part on the heel side of the shoe (A) is slightly outward (not straightly rearward), to the right and rear for the right foot and to the left and rear for the left foot, respectively. This is to reduce a chance of contact between the left and right seating parts (3) projecting rearward when the person brings his/her feet together to mutually contact the heel parts (9) and spread the tiptoes in an inverted “HA” katakana character shape.

FIGS. 12 and 13 illustrate an embodiment of claim 5, and is a so-called boot-shaped shoe (A) such as a boot or a rain boot. A front side of an upper part of the shoe where a part from the instep part (7) of the foot to the shin contacts is entirely opened as an opening part (D). A rear part of the shoe (A) where the heel part (9) and the calf in the lower leg rear part contact is made of a hard and strong material, and a seating part (3) is provided in the top part of the shoe (A) projecting horizontally rearward so that the shoe (A) can also be used as a stool. A leg part (41) of a bar shape is vertically fixed to the lower surface of the seating part (3) of the shoe (A), and a lower end part thereof touches the ground surface behind the heel part (9) of the shoe. Thus, when a person sits on the seating part (3), his/her weight acting rearwardly is supported by the leg part to increase stability. The leg part (41) integrally fixed to the seating part (3) is inserted into two guide holes (42) formed in the rear part of the shoe (A) at an upper location and a lower location thereof so that the leg part (41) is vertically slidable. The leg part (41) is able to move vertically within a range of about several centimeters along the rear part of the shoe (A). When the person sits on the shoe as a stool, the leg part (41) is lowered by the person's weight to the lowermost position to be in a state where the lower end part of the leg part (41) touches the ground; however, the lower end part of the leg part (41) is otherwise pulled up from the ground surface when the person is not sitting on the shoe so that he/she can walk easily. In order to achieve these states, the shoe which can also be used as a stool is characterized by providing a push spring (43), which is a shape memory member, for sliding the leg part (41) to be held at the uppermost position at all time. FIG. 12 illustrates an example in which the leg part (41) is lowered to the lowermost position, and FIG. 13 illustrates an example in which the leg part (41) is elevated to the uppermost position.

INDUSTRIAL APPLICABILITY

In the present situation where aged population has been increasing, middle-aged and elderly people need to play active roles also in the outdoor activities. However, in order to reduce the burdens of activities as much as possible, the shoes have such an effect that the person can rest his/her lower back anywhere at any time during the activities. In addition, since the shoes can also be utilized in outdoor sports over a long period of time, such as fishing, the shoes can be expected as future demanded industrial products.
