Description

  The present invention relates to a shoe capable of changing the height of the heel of the shoe sole, and more particularly to a shoe capable of changing the shape of the shoe sole as the heel height is changed.

  As shoes capable of changing the height of the buttock, an extensible shoe that can adjust the height of the buttock and changes the shape of the arch near the arch according to the height of the buttock is known. This telescopic shoe has a plurality of gears and the like that rotate inside the sole, and by combining these gears, the shape near the arch is changed according to the height of the buttocks on the sole. is there. In this way, not only changing the heel height, but also changing the shape of the sole, one of the reasons is that when the heel height is lowered, the toe portion of the shoe sole floats up This is for preventing the user from walking. For this reason, even if the height of the buttock is changed, the user can use this shoe without feeling uncomfortable like a normal shoe. In addition, the ability to change the height of the buttock is easy to walk in the same way as other shoes with a lower buttock height, so when encountering disasters such as earthquakes, the buttock height is lowered. It is also effective as a function to make it easier to evacuate passages and stairs where rubble is scattered.

  However, in order to manufacture the above shoes, it is necessary to have a plurality of parts such as gears for changing the shape of the sole, and furthermore, it is necessary to satisfy the strength that can withstand the weight of the user. Parts must be made of sturdy materials such as metal. For this reason, such a shoe becomes a heavy shoe as compared with a general shoe that does not have a function of changing the height of the buttocks. Therefore, a user who walks while wearing such shoes feels difficult to walk or feels tired.

In addition, the chances of encountering in the event of a disaster, etc. are extremely rare, and there is little need to change the height of the buttocks frequently, so shoes that are heavier than ordinary shoes are easy to use. The user is shunned as bad.

  Therefore, it is an object to provide a shoe that is light and easy to use even if it has a function of changing the height of the heel and the shape of the sole.

The shoe according to the present invention is provided such that “the sole body and the sole body thereof are provided in the vicinity of the front part of the arch or in the vicinity of the base of the toes, so that the sole body can be bent. In the bent sole and the shoe sole body, one end is supported forward of the bent portion, the relaxation member provided in the shoe sole body, and the heel portion of the shoe sole main body, and provided with a heel member. A height varying means for changing the height of the heel portion of the shoe sole body by changing the state of the heel member, and provided on the heel portion of the shoe sole body, according to the state of the heel member A bending means for bending or bending the bent portion by tensioning or relaxing the other end of the relaxing member.

  Here, the “height variable means” is provided in the sole body and changes the height of the heel portion of the shoe sole member, that is, the distance from the ground contact surface of the lower portion of the heel member to the upper sole member. This means shows a means and has a function of changing the height of the heel portion of the shoe sole body by expansion, contraction, attachment, or tilting of the heel member. In addition, the “relaxation member” is a member having flexibility and having difficulty in stretching in the longitudinal direction of the sole body. For example, the “relaxation member” is thin in a sheet shape used for manufacturing a leaf spring. There are special steel obtained by heat-treating a formed metal thin plate, a knitted plate formed by knitting a thin wire and coated with a resin, a special resin plate having a predetermined strength, and the like. The “bending portion” refers to a shape or the like that is provided in the sole body and is bent at the portion where the sole body bends. For example, a concave groove is formed at the bending position of the sole body in the short direction. In the part where the thickness of the bent part is made thinner than other parts and it is easy to bend, the part where the shoe sole body is bent and connected with parts such as a resin plate that can be bent, etc. is there.

  The shoe of the present invention is provided in a sole body, a bent portion provided in the sole body, a slack member provided to be slidable in the front-rear direction in the sole body, and a heel part of the sole body. It is composed of a height varying means and a bending means. The height varying means includes a heel member that supports the heel portion of the shoe sole body when the heel portion height is the highest, and the height of the heel portion of the shoe sole body is adjusted by extending, retracting, or tilting the heel member. This is for changing the height between a high state and a low state. The bending means is configured to bend the bending portion of the shoe sole body according to the height of the heel by sliding the relaxing member in the front-rear direction by tensioning or relaxing the relaxing member in conjunction with the height change of the heel. belongs to. Here, the height varying means and the bending means may include a portion in which the components are common, and clearly cannot be distinguished from each other, and may be included in either means.

  By providing these means, it is possible to make the front lower surface of the bent portion of the shoe sole body and the lower end surface of the shoe heel coincide with each other as the height of the heel portion changes. That is, when the user changes the height of the heel of the shoe, the shape of the sole body can be changed so that the user can easily walk. In addition, when a thin plate, such as a metal plate, is used as the relaxing member, the increase in the weight of the shoe due to the provision of the bending means can be kept small and the thickness of the sole body can be reduced. It becomes possible to make things. Further, by providing the bending means, the height varying means and the bending means can be concentratedly provided in the vicinity of the heel of the sole body, so that the center of gravity of the shoe can be brought close to the vicinity of the user's heel. It becomes. Therefore, it is possible to make it difficult for the user to feel the weight due to the provision of the variable means and the bending means.

  The shoe according to the present invention is “a rotation that is provided on the heel portion of the shoe sole body, the height varying means, or the bending means, and that can be manually or indirectly rotated with the vertical direction as a rotation axis. A moving shaft portion, and the height varying means changes the height of the heel portion of the shoe sole body by changing the state of the heel member by rotating or rotating the rotating shaft portion. The bending means tensions or relaxes the other end of the relaxation member by rotating or rotating the rotation shaft portion.

  The pivot shaft portion is provided on the heel portion of the shoe sole body, the height varying means, or the bending means. Here, “provided on the heel portion of the shoe sole body, the height varying means or the bending means” means that the rotating shaft portion is any one of the shoe sole body, the height varying means and the bending means. Are included as components common to two of them, and further included as a component common to all of them.

  The rotating shaft portion can be manually rotated or rotated directly or indirectly. Here, “directly or indirectly rotating or rotating manually” means, for example, that a pivotable knob part is provided on the rotating shaft part, and the rotating shaft part is rotated by pinching the knob part by hand. Alternatively, when the rotation is “directly”, a sliding portion is formed on the upper surface portion of the rotation shaft portion so that money can be vertically inserted, and the rotation shaft portion is fitted with the money in the sliding portion. Rotating or pivoting means “indirectly”. Therefore, the rotation shaft portion can be rotated or rotated without the need for preparing a tool or the like.

  The rotating shaft portion enables the height varying means and the bending means to function simultaneously by the operation. That is, when the pivot shaft rotates or pivots, the height varying means functions, and the heel member expands and contracts, attaches and detaches, or tilts to change the height of the heel portion of the sole body. The bending means also functions. By tensioning or relaxing the slack member according to the rotation of the rotation shaft, the slack member is slid in the front-rear direction to bend the bent portion of the sole body according to the height of the heel. It is supposed to let you.

  In the case of a height variable means that changes the height of the buttock by moving or expanding or contracting the heel member in the vertical direction, the rotation shaft is manually rotated directly or indirectly to rotate or rotate. According to the rotation of the moving shaft part, the height of the collar part is continuously increased or decreased by moving the collar member up and down or moving up and down. Further, the bending means is configured to bend the bending portion of the sole body according to the height of the heel by sliding the relaxing member in the front-rear direction by tensioning or relaxing the relaxing member according to the rotation of the rotation shaft portion. It can be made to. In addition, when a tiltable knob part is provided, when the knob part is laid down, a recess for storing the knob part is formed so that the knob part does not get in the way when wearing shoes. can do. In addition, since the knob portion is housed in the recess, it has the effect of suppressing the rotation or rotation of the rotation shaft portion, so that the collar member can be made immovable or fixed at an intermediate position. The user can use the shoe heel at a desired height.

  In the case of a height varying means that tilts the collar member to change the collar height, the height varying means is tilted by manually rotating or pivoting the pivot shaft part directly or indirectly. It is set to either impossible or tiltable, and the collar member is tilted in a state where the collar is high, the collar is raised, and is tiltable to change the collar member to a state where the collar is low. Further, the slack member is slackened according to the tilted state of the heel member, and the bent portion of the shoe sole body is bent according to the heel height.

  In the case of a height variable means for changing the height of the buttock by attaching and detaching the heel member, the height variable means is mounted by manually rotating or rotating the rotation shaft part directly or indirectly. It is set to either possible or detachable, and the state is changed between a high state of the heel portion to which the heel member is attached and a low state of the heel portion to which the heel member is attached and detached. The bending means tensions the loosening member to bend the bent portion when the collar member is attached, and relaxes and changes the bent portion when the detachable state is attached.

  As described above, the rotation shaft portion provided on the heel portion of the shoe sole member allows the height changing means and the bending means to function simultaneously, simplifying the structure and reducing the number of parts. It becomes possible. Further, the user can easily change the height of the heel and the sole member by operating the rotation shaft portion.

The shoe according to the present invention is as follows: "The height varying means moves or stretches the heel member up and down to change the heel height of the sole body, and the bending means includes the heel member. According to the moving state or the stretched state, the other end of the loosening member is tensioned or relaxed to bend the bent portion.

  The height of the heel part of the shoe sole body changes when the pivoting shaft part is rotated or rotated so that the height variable means moves or expands / contracts the heel member in the vertical direction. It can be changed to a low state. In addition, since the eaves member has a structure that moves or expands and contracts in the vertical direction, it is possible to provide height varying means concentrated on the eaves portion. The bending means is configured to stretch the relaxing member in accordance with the movement state or the expanded / contracted state of the heel member. When the relaxing member is relaxed, the front of the shoe sole body is relatively relative to the shoe sole in the front-rear direction. It moves and can bend the bent portion according to the height of the buttocks. In addition, the tension member can be tensioned or relaxed in proportion to the moving direction of the flange member. Thus, since the mechanism for bending the sole body can be simplified, the number of parts can be reduced. Therefore, even if the height varying means and the bending means are provided, an increase in the weight of the entire shoe can be suppressed to a small level.

  The shoe according to the present invention is described as follows: "The height varying means is provided to tilt the heel member, and changes the tilt state of the heel member to change the heel height of the shoe sole body, The bending means tensions or relaxes the other end of the relaxing member according to the tilting of the flange member to bend the bent portion.

  The heel member is attached to the sole body so as to tilt. At this time, the tilting direction is tilted in the front-rear direction, but the “front-rear direction” does not have to be exactly the front-rear direction, and includes a case where the direction is tilted. The height varying means rotates or pivots the pivot shaft to fix the collar member so that it does not tilt with the collar raised, or releases the anchor member so that the collar member tilts. Is. As a result, the height of the heel portion of the shoe sole body can be changed in two ways: a high state and a low state. The bending means is configured to relax the relaxing member according to the tilting state of the heel member, and the bending portion of the shoe sole body can be bent in two ways according to the heel height. That is, the tension member is tensioned when the collar member is fixed, or relaxed when the fixation is released. Since the mechanism of the height varying means can be simplified, the number of parts can be further reduced, and the increase in the weight of the entire shoe can be reduced.

The shoe according to the present invention is as follows: "The height changing means is such that the heel member is detachable, and the height of the heel portion of the shoe sole body is changed by the attachment / detachment of the heel member; According to the attachment / detachment state of the collar member, the other end of the relaxation member is tensioned or relaxed to bend the bent portion.

  The heel member is detachably attached to the sole body. Then, the height varying means turns or turns the pivot shaft portion to make the heel member detachable or impossible. And when the heel member is attached, the heel height of the sole body is set to a high state, and when the heel member is attached / detached, the heel portion height is set to a low state. Is possible. The bending means is configured to relax the relaxing member according to the attachment / detachment state of the heel member, and can bend the bending portion of the shoe sole body according to the height of the heel portion. That is, it is possible to change the bending state of the bent portion in two ways by tensioning the loosening member when the collar member is attached and bending the bent portion, and relaxing when the detachable state is attached. By providing such a height varying means, the mechanism of the height varying means can be simplified and the number of parts can be reduced. Further, when the height of the heel portion is lowered, the heel member is separated from the sole body, so that the shoe weight can be reduced by the amount corresponding to the heel member.

The shoe according to the present invention is described as follows: "The height varying means is attached to the heel member so as to move up and down along the rotation shaft portion, and depending on a rotation amount or a rotation amount of the rotation shaft portion, The height of the heel portion of the shoe sole body is changed, and the bending means attaches the other end of the relaxation member so as to move up and down along the rotation shaft portion, and according to the rotation amount or the rotation amount. The other end of the relaxing member is tensioned or relaxed to bend the bent portion.

  The height of the heel portion of the shoe sole body changes according to the amount of rotation or the amount of rotation of the rotation shaft portion as the height varying means moves or expands or contracts the heel member vertically along the rotation shaft rod. Thus, it is possible to change between a high state and a low state. Here, the “rotation amount or rotation amount” means the number of rotations or rotations of the rotation shaft rod with respect to a certain position. Further, the bending means is configured to move and loosen the relaxing member along the rotating shaft bar in accordance with the amount of rotation or the amount of rotation of the rotating shaft portion common to the height varying means. When the relaxing member relaxes, the front of the shoe sole body moves relative to the shoe sole in the front-rear direction, and the bent portion can be bent according to the height of the heel portion. That is, the relaxing member can be continuously tensioned or relaxed in proportion to the amount of movement of the collar member, and the collar height can be set to an intermediate height for use.

The shoe according to the present invention is described as follows: "The bending means includes a first threaded portion threaded at a first pitch width in a lower portion of the rotating shaft portion from the sole body, and the slackening. A first screw hole portion screwed at the first pitch width at the other end of the member, and the relaxation member is provided by screwing the first screw portion into the first screw hole portion. The height varying means includes a second threaded portion provided at a lower portion of the rotating shaft portion than the first threaded portion and engraved with a second pitch width. A second screw hole portion which is perforated downward in the upper portion of the flange member and is screwed with the second pitch width, and the second screw hole is the second screw hole. It is provided with the flange member by being screwed into a part, and provided with the height variable means so as not to be rotatable.

Here, the “first threaded portion”, the “second threaded portion”, the “first threaded hole portion”, and the “second threaded hole portion” are not limited to those having a right-hand thread, but are left-handed. It is also included. When all of the first threaded portion, the second threaded portion, the first threaded hole portion, and the second threaded hole portion are left-handed, movement of the flange member and relaxation of the slackening member may occur. This is similar to the state in which the rotation direction of the rotation shaft portion is reversed.
Further, the “pitch width” indicates a width between screw threads or screw valleys screwed into the threaded portion or the screw hole portion.

  According to this, the rotating shaft part provided in the shoe sole body includes the first threaded part and the second threaded part connected to each other. When the rotation shaft portion is rotated or rotated by operating the rotation shaft portion, the first screw hole portion (relaxation member) into which the first screw portion is screwed and the second screw portion The second screw hole portion (saddle member) into which is inserted is moved upward or downward in the rotational axis direction of the rotational shaft portion.

  Here, the relaxation member relaxation tension is set to be suitable for the position of the flange member by the ratio of the first pitch width to the second pitch width. That is, the pitch width ratio between the first pitch width and the second pitch width is such that the collar member moves downward and the collar part becomes higher, and the collar member moves upward and the collar part becomes lower. The bent portion of the sole body is set to be bent at an angle suitable for the moving state of the heel member. By differentiating the pitch width between the first pitch width and the second pitch width, it is possible to provide a function similar to the function of combining two gears having different diameters.

  When the first threaded portion, the second threaded portion, the first threaded hole portion, and the second threaded hole portion are of a right-hand thread, the rotational shaft portion is moved to the right by the rotational operation. When rotated, the second screw hole portion into which the second screw portion is screwed moves moves upward in the rotation shaft portion, that is, the heel member moves toward the shoe sole body. As a result, the height of the ridge can be reduced. At the same time, the first screw hole portion into which the first screw portion is screwed also moves upward, that is, the multiple ends of the relaxation member also move upward. And when the 1st screw hole part (relaxation member) approaches a sole body, the tension member which was tense can be relaxed and the bent part angle of a sole body can be made into the expanded state. That is, the bent portion angle changes depending on the movement position of the second screw hole portion (saddle member).

  Next, when the rotation shaft portion is rotated in the left direction by the operation of the rotation shaft portion, the second screw hole portion (the hook member) into which the second screw portion is screwed is formed on the rotation shaft portion. It moves downward and the heel member moves away from the sole body direction. As a result, the height of the ridge can be increased. At the same time, the first screw hole portion (relaxation member) into which the first screw portion is screwed also moves downward. And when the 1st screw hole part (relaxation member) leaves | separates from a shoe sole main body, the relaxed relaxation member can be tensioned and the bending part angle of a shoe sole main body can be made small.

  Thus, since the same function as the state which combined several gears with the rotating shaft part can be provided, it becomes possible to change simultaneously the height of a heel part and the bending part angle of a sole body. . Therefore, the number of parts can be reduced as compared with conventional shoes, and the shoes can be reduced in weight. Since the heel height continuously changes, the user can use the shoe of the present invention at a desired heel height.

  Further, when the second threaded portion is thicker than the first threaded portion, that is, the outer diameter of the second threaded portion and the inner diameter of the second threaded hole portion are set to the first threaded portion. When the outer diameter of the engraved part and the inner diameter of the first screw hole part are made larger, the second screw hole part is moved upward (in the direction of the shoe sole body) by rotating the rotating shaft part to the right. Since the second screw hole portion is in contact with the first screw portion and is not prevented from moving, the hook member can be moved also to the first screw portion. Therefore, the range of movement of the eaves member can be expanded, and the amount of change in eave height can be increased. Therefore, even in a shoe having a high heel portion such as a high heel, it is possible to increase the height difference when the heel portion is changed.

  In the shoe of the present invention, “the height varying means is provided at a lower portion of the rotating shaft portion, and the heel member cannot be tilted by the rotation of the rotating shaft portion, or the inability to tilt is released. It is due to the function, and the tilting state of the heel member is changed to change the height of the heel portion of the sole body, wherein the bending means connects the multiple ends of the relaxation member to the heel member, It is also possible to adopt a configuration in which the tension member is tensioned when the eaves member is upright and the tension member is relaxed and the bent portion is bent when lying down.

  The heel member is attached to the sole body so as to tilt. At this time, the tilting direction is tilted in the front-rear direction, but the “front-rear direction” does not have to be exactly the front-rear direction, and includes a case where the direction is tilted. The height varying means rotates or pivots the pivot shaft to fix the collar member so that it does not tilt with the collar raised, or releases the anchor member so that the collar member tilts. Is. As a result, the height of the heel portion of the shoe sole body can be changed in two ways: a high state and a low state. The bending means is configured such that the other end of the relaxing member is connected to the flange member, and the relaxing member is relaxed according to the tilting state of the flange member. That is, the tension member can be tensioned or relaxed according to the tilting of the collar member.

  The shoe according to the present invention is “the height varying means is provided at a lower portion of the rotation shaft portion, and has a function of making the heel member detachable or non-detachable by rotation of the rotation shaft portion. The height of the heel portion of the shoe sole body is changed by attaching and detaching the heel member, and the bending means is provided in the shoe sole body or the heel member, and when the heel member is attached, There is provided locking means for locking the other end of the relaxing member while keeping the bent portion bent by tensioning the member, and releasing the locking of the other end and releasing the relaxing member at the time of detachment. It is characterized by being ".

  The heel member is detachably attached to the sole body. Then, the height varying means turns or turns the pivot shaft portion to make the heel member detachable or impossible. Then, the height of the heel portion of the shoe sole body is increased when the heel member is attached, and the height of the heel portion is decreased when the heel member is detached. The bending means locks and tightens the other end of the relaxation member when the collar member is attached, and bends the bent portion. When the attachment means is detached, the bending means releases the other end of the relaxation member and relaxes. By increasing the bending angle, the bending portion of the shoe sole body can be bent according to the height of the heel portion, that is, depending on the attachment / detachment state of the heel member, and the bending portion can be bent. Become.

  The shoe according to the present invention is characterized in that the relaxation member is characterized in that it has flexibility and does not expand and contract in the longitudinal direction of the sole body.

  The relaxation member is flexible and has a property of not extending in the longitudinal direction of the sole body. By having flexibility, the relaxation member can be deformed in response to the bending of the shoe sole member, and the shoe sole member can easily slide back and forth. By having the characteristic that the shoe sole member does not extend, the shape of the shoe sole member can be maintained in a bent state by the bending means. This is because when the shoe sole member is extended, the front lower surface of the bent portion of the shoe sole main body and the shoe lower end surface of the shoe cannot coincide with each other. Since the shoe sole member has such a property, it can be used while wearing the shoe with the heel portion of the shoe raised.

  The shoe according to the present invention is characterized in that “the connecting means is a thin metal plate having flexibility”.

  By using a thin metal plate having flexibility as the relaxing member, the relaxing member can be provided with flexibility and non-extension.

  Thus, the shoe of the present invention can reduce the weight of the entire shoe while having the function of changing the height of the heel and the function of changing the shape of the shoe sole. Further, since the number of parts can be reduced, the production cost can be kept low. In addition, since a shoe having a high buttocks can be changed to a low state in a disaster such as an earthquake, an effect as a shoe having an emergency function can be expected.

Two circular disks 15 and 16 are fixed to the rear portion of the connecting plate 5 with the connecting plate 5 interposed therebetween. Here, the disks 15 and 16 are of a size that can pass through the support hole 22a. At the center of the discs 15 and 16, a screw hole 17 is provided which is drilled through the connecting plate 5 and the discs 15 and 16 and is screwed with a pitch width A on the inner surface. The screw hole 17 functions as a first screw hole portion.

  As shown in FIG. 3, the connecting plate 5 is arranged in the long concave portion 9, and can be slid in the front-rear direction by inserting the locking portion 14 a into the locking hole 5 a and further engaging the locking ring 18. Are attached to the mounting bracket 14. Then, the rear end of the connecting plate 5 provided with the screw holes 17 passes through the through hole 9a, the first rotating shaft rod 11 is screwed into the screw holes 17, and the front portion of the shoe and the heel portion 4a are connected to the connecting plate. 5 is connected. At this time, when the first rotation shaft 11 rotates, the disks 15 and 16 move up and down along the first rotation shaft 11. Further, since the connecting plate passage 24 is provided, the connecting plate 5 can be moved up and down along the first pivot shaft 11 and relaxed by the vertical movement of the disks 15 and 16. Yes. That is, the connecting plate 5, the rotation shaft rod 6 (first rotation shaft rod 11), the knob portion 13, the mounting bracket 14, and the disks 15 and 16 function as bending means.

  The rotating shaft rod 6 is composed of a first rotating shaft rod 11 and a second rotating shaft rod 20 each having a knob portion 13 on the shaft head portion 10a. In other words, a second rotating shaft rod 20 having a diameter larger than that of the first rotating shaft rod 11 is provided below the first rotating shaft rod 11. Then, as shown in FIG. 3, a screw hole 20a is formed in the axial direction at the upper part of the second rotating shaft rod 20, the screw hole 20a and the first rotating shaft rod 11 are screwed together, and the side surface portion thereof. The first rotating shaft rod 11 and the second rotating shaft rod 20 are connected by punching a hole 23a and driving the pin 23 into place. The entire side surface of the second rotary shaft 20 is threaded with a pitch width B. The first rotating shaft rod 11 functions as a first threaded portion, and the second rotating shaft rod 20 functions as a second threaded portion.

  The movable hook portion 21a has a horizontal cross section similar to the shape of the support hole 22a. That is, a cross-sectional shape similar to a shape in which the upper portion of the U-shape is closed by a line is a three-dimensional shape extending in the vertical direction, and has a flat plane portion on the front side surface of the movable collar portion 21a. On the upper surface of the movable flange portion 21a, there is provided a screw hole 19 which is perforated in the longitudinal direction and is screwed into the inner side surface portion with a pitch width B. The movable collar portion 21 a is inserted into the support hole 22 a of the collar body 22 and is slidably supported, and the lower portion of the pivot shaft 6 (second pivot shaft rod 20) is screwed into the screw hole 19. It is attached to the body 22. The screw hole 19 functions as a second screw hole portion.

  Here, since the movable collar portion 21a is not cylindrical, when it is inserted into the support hole 22a, it can slide in the vertical direction but does not rotate with the vertical direction as a rotation axis. Therefore, when the knob portion 13 is raised and the pivot shaft 6 is manually pivoted, the movable collar portion 21a can be moved up and down along the second pivot shaft rod 20. The pivot shaft 6 (second pivot shaft 20), the collar body 22 and the movable collar 21a function as height varying means.

  Here, the first rotating shaft rod 11, the screw hole 17, the second rotating shaft rod 20, and the screw hole 19 are all screwed with a right-hand thread, and the thread type is triangular. A type called a screw is used. However, it is not limited to the type of such a screw, and may be replaced with, for example, all of them screwed with a left-hand thread, and the screw thread is other than a triangular screw type, for example, a square screw. Alternatively, a trapezoidal screw, a round screw, or a sawtooth screw type may be used. The pitch type may be a coarse pitch or a fine pitch. Here, when the first rotation shaft rod 11, the screw hole 17, the second rotation shaft rod 20, and the screw hole 19 are all left-handed, the height of the heel portion of the shoe 1a and the sole body 2 The bending change has the same effect as the state in which the rotation direction of the rotary shaft 6 is reversed.

  The pitch width A of the first rotating shaft rod 11 and the screw hole 17 and the pitch width B of the second rotating shaft rod 20 and the screw hole 19 are in the relationship of pitch width A <pitch width B, and the pitch width A Indicates that the pitch width B is fine and the pitch width B is coarse, the height of the heel portion 4a by moving the movable heel portion 21a by rotating the first rotation shaft 11 and the bending angle of the sole body 2 at the bending portion 2a. And is determined by. That is, the range L1 in which the disks 15 and 16 are movable in the first rotation shaft rod 11, the range L2 in which the movable collar portion 21a is movable in the second rotation shaft rod 20, and the length of the movable collar portion 21a. The height of the heel portion 4a and the bending angle of the sole body 2 at the concave portion 2a are determined. In addition, the discs 15 and 16 are set so as to come into contact with and be fixed to the second pivot shaft 20 when the movable collar portion 21a moves downward and the height of the heel portion 4a reaches the maximum. In addition, the knob portion 13 is set so as to lie down and be stored in the recess 7.

  In the shoe sole body 2, a rear sole 25 is attached to the upper surface behind the front sole 3 so as to cover the concave portion 7 and the long concave portion 9. As shown in FIG. 2, the rear bottom 25 is raised up in the vicinity of the collar portion of the rear bottom 25 so that the knob 13 can be raised and rotated. Around the sole body 2, when the shoe 1 is worn, a front foot holding portion 26 that holds the front portion of the foot of the person wearing the shoe 1, and a rear foot holding portion that holds the rear periphery from the side of the foot 27 is provided. The front foot holding portion 26 and the rear foot holding portion 27 are connected to the left and right sides between the front foot holding portion 26 and the rear foot holding portion 27 and in the vicinity of the concave portion 2a of the sole body 2. The elastic member 28 is interposed, and expands and contracts by bending the concave portion 2a. The lower part of the elastic member 28 is formed in an arc shape, and is provided with an opening 28a for allowing the air inside the shoe 1 to enter and exit so as to be easily bent at the concave portion 2a.

  Next, the operation and effect of the shoe 1a according to the first embodiment configured as described above will be described.

  FIG. 1 shows a state in which the movable hook 21a has moved downward, in other words, the movable hook 21a is located at the lower end of L2. At this time, the discs 15 and 16 and the upper end of the second rotating shaft rod 20 are in contact with each other, and the knob portion 13 is laid back and stored in the recess 7. Therefore, the rotation shaft 6 is fixed and cannot rotate, and the movement of the movable collar portion 21a is prevented. Therefore, even if a user puts on the shoe 1a and puts weight on the heel portion 4a, the movable heel portion 21a is fixed and does not move, and the heel portion 4a can be used in the highest state. .

  Further, the disks 15 and 16 are in a state of moving downward and tensioning the connecting plate 5. That is, the discs 15 and 16 are positioned at the lower end of L1 and the connecting plate 5 is tensioned, and the front portion of the sole body 2 is pulled backward. That is, the connecting plate 5 draws the mounting bracket 14 fixed to the front sole 3 backward, and the concave portion 2a of the shoe sole body 2 is bent. At this time, by selecting an appropriate length of the pivot shaft 6 and adjusting the position of the through-hole 9a in the sole body 2, the sole body 2 in front of the lower end of the movable saddle portion 21a and the concave portion 2a is used. Is set to coincide with the bottom of the same plane.

  Since the rotation axis 6 is fixedly connected to the first rotation axis 11 and the second rotation axis 20, when the shaft head 10 a is rotated, The second rotating shaft rod 20 rotates at the same time. Therefore, when the knob portion 13 is operated to rotate or rotate the rotary shaft 6, the discs 15 and 16 screwed into the first rotary shaft 11 and the second rotary shaft 20 are moved. The movable hook portion 21a that is screwed is moved upward or downward in the direction of the rotation axis of the rotation shaft 6. As shown in FIG. 2, when the rear sole 25 of the shoe 1a is rolled up and the tiltable knob portion 13 is raised upright, the knob portion 13 is easily held by hand, and the pivot shaft 6 is directly and manually operated. Can be rotated. Therefore, the rotation shaft 6 can be directly rotated manually without using a tool. As shown in FIG. 1, when the rotary shaft 6 is rotated clockwise by pinching the knob portion 13 with the heel portion 4 a being high, the movable collar portion 21 a is pivoted along the second rotary shaft 20. The disk 10 can be moved in the direction (upward) of the portion 10a, and at the same time, the disks 15 and 16 can be moved in the direction (upward) of the axial head 10a along the first pivot shaft 11.

  As described above, when the knob portion 13 is pinched and the pivot shaft 6 is rotated to the right, the movable collar portion 21a screwed into the second pivot shaft 20 moves upward, and the sole body Approach 2 direction. Thereby, the height of the heel part 4a can be gradually lowered. At the same time, the disks 15 and 16 screwed into the first pivot shaft 11 also gradually move upward, bringing the disks 15 and 16 closer to the sole body, so that the tensioned connecting plate 5 is removed. It can be gradually relaxed and the angle of the bent part of the sole body can be widened. Therefore, the bending portion angle can be changed according to the amount of movement of the movable flange portion 21a with respect to the disks 15 and 16.

  Here, the outer diameter of the first pivot shaft 11 is formed to be smaller than the inner diameter of the screw hole 19 of the movable flange 21a. When the movable rod portion 21a is moved upward by rotating the rotation shaft rod 6, the movable rod portion 21a is not obstructed by the first rotation shaft rod 11, so that the first rotation shaft rod It is also possible to move to the range 11 (L1). Therefore, the moving range L2 of the movable collar portion 21a can be expanded to the range of L1, and the amount of change in the height of the heel portion 4a can be increased. Therefore, even in a shoe having a high heel portion such as a high heel, the height difference of the heel portion can be increased.

  Further, the bent portion angle is set to be suitable for the height of the heel portion 4a by the ratio of the first pitch width to the second pitch width. That is, the pitch width ratio between the first pitch width and the second pitch width is such that the movable heel portion 21a moves downward and the heel portion 4a becomes higher, and the movable heel portion 21a moves upward. In the state where the heel portion 4a is lowered, the concave portion 2a of the shoe sole body 6 is set to bend at an angle suitable for the height of the heel portion 4a. Therefore, by making the pitch widths of the first pitch width and the second pitch width different, the rotary shaft 6 can be provided with a function similar to the function of combining two gears having different diameters. Therefore, the number of parts can be reduced as compared with the conventional shoe, and the shoe 1a can be reduced in weight.

  When the movable heel portion 21a is in a predetermined position (the upper end of the movable heel portion 21a is within the range of L2), the knob portion 13 can be laid down behind the shoe 1a (the state shown in FIG. 2). At this time, when the knob portion 13 is laid down to the rear of the shoe 1a, the pivot shaft 6 becomes unrotatable or unrotatable, and movement of the disks 15, 16 and the movable collar portion 21a is prevented. That is, it becomes possible to make the heel member 21a immovable at an intermediate position (the upper end of the movable heel portion 21a is within the range of L2), and the heel height of the shoe 1a is the height of the heel portion 4a shown in FIG. And, it can be set to an intermediate height between the height of the heel portion 4a shown in FIG. At this time, by adjusting the pitch width ratio between the first pitch width and the second pitch width, the lower end of the heel portion 4a and the bottom surface of the sole body 2 in front of the concave portion 2a coincide with each other on the same plane. It is like that.

  Therefore, the knob portion 13 and the recess 7 have a function of preventing the rotation of the rotation shaft 6. That is, even if the movable hook part 21a is moved to a position desired by the user (the upper end of the movable hook part 21a is within the range of L2), the pivot shaft 6 can be moved by fitting the knob part 13 into the recess 7. It is possible to prevent it from rotating freely, and to make it impossible to freely move the movable collar portion 21a. And the user can set and use the height of the heel part 4a freely. Further, since the knob portion 13 can be laid down and fitted into the recess 7, the knob portion 13 does not get in the way when the user wears the shoe 1a.

  Further, when the pivot shaft 6 is rotated to the right, the lower end of the movable collar portion 21a is completely accommodated in the collar body 22 as shown in FIG. At the same time, the disks 15 and 16 move in the direction of the axial head 10a (upward), whereby the connecting plate 5 is loosened and the bending angle of the concave portion 2a of the sole body 2 is maximized. When the knob portion 13 is in a state in which it can be laid down toward the back of the shoe 1a (the state shown in FIG. 2), the right rotation of the rotary shaft 6 is stopped and the knob portion 13 is laid down in the recess 7 Store. And a user can use it in the state which made the height of the heel part 4a the lowest. Thus, the state where the heel portion 4a is the lowest (the state shown in FIG. 2) is suitable for the user to condemn the scattering of rubble and the like when a disaster such as an earthquake occurs, and can cope with the disaster. It is effective as a possible shoe.

  Next, in order to increase the height of the heel portion 4a, the pivot shaft 6 may be rotated in the reverse direction to the above. That is, the knob portion 13 is operated to rotate the pivot shaft 6 in the left direction. Then, the movable collar portion 21a screwed into the second rotation shaft rod 20 moves downward (in a direction away from the shoe sole body 2) to increase the height of the heel portion 4a. Can do. At the same time, the disks 15 and 16 screwed into the first pivot shaft 11 also move downward (the lower end of L1), tension the loosened connecting plate 5, and the bent portion of the shoe sole body 2 The angle can be reduced, that is, it can be gradually bent at the concave portion 2a.

  When the heel portion 4a is in the highest state and the knob portion 13 can be laid down to the rear of the shoe 1 (the state shown in FIG. 2), the knob portion 13 stops turning counterclockwise, and the knob portion 13 Is laid sideways in the recess 7 and stored. Then, when the discs 15 and 16 move in the direction of the shaft head 10a (the lower end of L1), the connecting plate 5 is most tensed, and the bending angle of the concave portion 2a of the sole body 2 can be reduced. . At this time, as shown in FIG. 1, the lower end of the heel portion 4a and the bottom surface of the sole body 2 in front of the concave portion 2a coincide with each other on the same plane. And a user can use it in the state which made the height of the heel part 4a the highest.

  By the way, when the user is walking while wearing the shoe 1a in the state of FIG. 1 or FIG. 2, the state where the concave portion 2a of the shoe sole body 2 tries to bend further occurs. In other words, the angle of the bent portion of the shoe 1a always changes due to the walking motion, and the angle is further reduced from the angle at which the connecting plate 5 is bent and bent. At this time, the connecting plate 5 is attached to the mounting bracket 14 so as to be slidable in the front-rear direction, and the long recess 9 is formed to be longer forward than the mounting bracket 14, so that the connecting plate 5 slides forward. Is possible. Therefore, even if the sole body 2 is further bent, the connecting plate 5 is not stretched inside the elongated recess 9, and the connecting plate 5 is bent or deformed inside the elongated recess 9. It is possible to prevent troubles that the plate 5 cannot move, damage to the shoe sole body 2, and the like. The user can wear and use the shoes 1a without feeling uncomfortable like the conventional shoes.

  Therefore, if the shoe 1a of this embodiment is used, the rotary shaft 6 is provided with two types of threaded portions having different pitch widths, that is, the first rotary shaft 11 and the second rotary shaft 20. By providing the above, it is possible to function the relaxation of the connecting plate 5 and the movement of the movable heel part 21a at the same time without using a plurality of gears as in conventional shoes. Moreover, compared with the shoes which change the conventional heel part and shoe sole part, a structure can be simplified because a plurality of gears and parts related thereto can be omitted. Therefore, the number of parts can be reduced, and the shoe 1a can be reduced in weight. Further, since the height of the heel portion 4a can be continuously changed, the user can use the shoe 1a of the present invention at a desired heel height.

  Moreover, it may replace with the structure of said 1st Embodiment, and may use another thing. For example, instead of the knob portion 13, a knob portion 13a having a shape shown in FIG. In this case, the knob portion 13a is processed into a semicircular arc shape, and has a semicircular cutout portion 13b in part. At this time, the concave portion 7 has a circular shape, and has a protruding portion 2 b having the same shape as the cutout portion 13 b at the rear end of the concave portion 7. By having the notch portion 13b and the protruding portion 2b in this manner, the notch portion 13b of the knob portion 13a protrudes when the knob portion 13a is laid down rearward of the shoe 1a in the same manner as the knob portion 13 of FIG. Locked by the portion 2b, the rotating shaft rod 6 cannot be rotated or rotated, and the movement of the disks 15, 16 and the movable flange 21a can be prevented. That is, it becomes possible to make the collar member 21a immovable at an intermediate position (in the range of L2 in FIG. 1). Further, the rear foot holding portion 27 and the elastic member 28 may be omitted, and the shoe without the rear foot holding portion 27 may be provided.

[Second Embodiment]
Hereinafter, the present invention is embodied in a high-heeled shoe generally called a high heel, and a structure of a shoe 1b having a function of changing the heel height by tilting the heel portion is based on FIGS. 5 to 9. explain.

  As shown in FIG. 5, the shoe 1 b is provided on a sole body 2 as a sole body, a front sole 3 provided on the upper surface of the sole body 2, and a heel part of the sole body 2. A heel portion 4b having a height varying means and a bending means; and a connecting plate 5 as a relaxation member provided to connect the front base 3 and the heel portion 4b.

  The shoe sole body 2 is made of synthetic resin or wooden, and is formed in a shape similar to the shape of a person's sole, like a normal shoe, and the front portion is flat on the bottom surface. In the cross-sectional shape of FIG. 5, it is formed in a shape curved upward toward the rear. In the vicinity of the boundary between the flat portion and the curved portion (arch portion), a concave portion 2a that functions as a bent portion is formed in the short direction of the shoe sole body 2. By forming the recessed part 2a, the thickness of the part becomes thin and it can be bent.

  The heel portion 4 b is composed of a tilting collar portion 21 b and a collar body 22. The heel body 22 is made of synthetic resin or wooden and is attached to the heel of the shoe sole body 2. The heel body 22 has a U-shaped horizontal cross-sectional shape, in other words, a shape similar to a horseshoe shape in which the front-rear direction is reversed. It is processed into the same shape. And it is formed so that the periphery may become thin while being rounded downward.

  As shown in FIG. 8, the tilting collar part 21 b has a shape in which the upper part is sandwiched in the U-shape of the collar body 22, that is, a shape similar to a semi-cylindrical shape, and has a cross-sectional area downward from the middle thereof. Is smaller, that is, it is formed in a shape in which a semi-conical shape is combined with a lower portion of a shape similar to the semi-cylindrical shape. A metallic tilting shaft bar 38 is inserted through and attached to the upper front portion of the tilting collar portion 21b. And the upper part of tilting collar part 21b is arrange | positioned so that it may be inserted between U characters of the collar part main body 22, and two recessed parts facing the part in which the tilting shaft bar 38 of the inner side part of the collar part main body 22 is located are formed. Then, the tilting rod portion 21b is attached so as to be tiltable by pivoting the tilting shaft rod 38 to both concave portions thereof. The collar part main body 22, the tilting shaft rod 38, and the tilting collar part 21b function as height varying means.

  On the upper surface of the heel portion of the shoe sole body 2 and at the rear position of the tilting heel portion 21b, a concave portion 7 formed in the same shape as the shaft head portion 10b is formed, and a shaft mounting hole 29 is formed at the center thereof. Perforated to the inside of the heel body 22 in a direction perpendicular to the upper surface of the shoe sole body 2. A semicircular hole 35 having a semi-cylindrical shape is formed on the inner surface of the collar body 22 at the same position as the lower end of the shaft mounting hole 29 so as to be perpendicular to the shaft mounting hole 29. . In the upright position of the movable flange 21b (state shown in FIG. 5), a semi-cylindrical shape is formed at the same position as the semi-disk-shaped hole 35 so as to form a circular space connected to the semi-disk-shaped hole 35. A formed locking hole 33 is formed.

  The shaft mounting hole 29 is provided with a rotating shaft bar 31 having a disk-shaped shaft head portion 10b shown in FIG. On the upper surface portion of the shaft head portion 10b, there is formed a slot portion 32 capable of vertically inserting money. The pivot shaft 31 is provided with a semi-disc-shaped locking plate 30 at the same position as the semi-disc-shaped hole at the lower end. Therefore, the rotation shaft 31 is in a state in which it can rotate but cannot be detached from the collar body 22. Further, when the shaft head 10 b is rotated, a part of the locking plate 30 protrudes from the semicircular hole 35 or is accommodated in the semicircular hole 35.

  The sole body 2 is provided with a long concave portion 9 that is formed long in the front-rear direction of the shoe 1b from the vicinity where the toes worn on the shoe 1b are located to the vicinity of the heel body 22. A through hole 9a that penetrates obliquely in the rear direction is formed at the rear end. A front shoe sole 3 having the same shape as the front upper surface of the shoe sole body 2 is laid on the front upper surface of the shoe sole body 2, and a plate-like shape shown in FIG. A mounting bracket 14 is provided. The mounting bracket 14 includes a columnar locking portion 14a that protrudes downward.

  The connecting plate 5 is a thin plate having a thickness of 0.2 mm or less and is formed long in the front-rear direction of the shoe 1b. As the material, special steel obtained by heat-treating JIS G3311 is used. Since this special steel is thin, it is light, has moderate flexibility, and is difficult to stretch. Here, instead of the special steel, a mesh plate made by knitting a thin wire and coated with a resin, a special resin plate having a predetermined strength, or the like may be used. A locking hole 5 a that is elongated in the front-rear direction of the shoe 1 b is formed in the front portion of the connecting plate 5, and a hole 5 b is provided in the rear end portion of the connecting plate 5.

  The connecting plate 5 is disposed in the long concave portion 9, and the front end of the connecting plate 5 can be freely slid in the front-rear direction by fitting a locking ring 18 into a locking portion 14a penetrating the locking hole 5a. As shown in FIG. The rear end of the connecting plate 5 passes through the through hole 9a, is inserted into a plate-like hole 42 formed on the side surface of the tilting saddle portion 21b, and the pin 40 driven from the upper portion of the tilting saddle portion 21b is connected to the connecting plate. 5 is attached to the tilting collar portion 21b by penetrating through the hole 5b. Here, the positions where the through holes 9a and the plate-like holes 42 are provided are determined by the relationship between the height of the heel portion 4b and the bending angle of the sole body 2 at the concave portion 2a when the tilting collar portion 21b is upright. . That is, when the tilting heel portion 21b stands upright and the concave portion 2a of the sole body 2 is bent, the lower end of the heel portion 4b and the bottom surface on the front side of the concave portion 2a of the sole body 2 coincide with each other. It is set to do. The connecting plate 5, the rotating rod shaft 31, and the mounting bracket 14 function as bending means.

  As shown in FIG. 5, when the tilting collar part 21 b is laid sideways and the heel part 4 b is lowered (the state of FIG. 6), the convex parts 36 for maintaining the tilting collar part 21 b in the laterally tilted state are Two concave portions 37 (FIG. 7) are provided on both side surface portions of the tilting collar portion 21 b provided at the inner side surface and sandwiched by the both convex portions 36. For this reason, even when the heel portion 4b is lowered, the tilting collar portion 21b is kept in the sideways state and can be used with the heel portion 4b lowered.

  In the shoe sole body 2, a rear sole 25 is attached to the upper surface behind the front sole 3 so as to cover the concave portion 7 and the long concave portion 9. As shown in FIG. 6, in the vicinity of the collar portion of the rear floor 25, the rear floor 25 rises upward so that the shaft head 10b can be rotated. Around the sole body 2, a front foot holding portion 26 that holds the front portion of the foot when the shoe 1 b is worn, and a rear foot holding portion 27 that holds the rear periphery from the side portion of the foot are attached. Yes. The front foot holding portion 26 and the rear foot holding portion 27 are connected to the left and right sides between the front foot holding portion 26 and the rear foot holding portion 27 and in the vicinity of the bent portion 2a of the sole body 2. An elastic member 28 is interposed. The lower part of the expansion / contraction member 28 is formed in an arc shape, and is provided with an opening 28a for allowing air to easily enter and exit and to be bent at the concave portion 2a.

  Next, the operation and effect of the shoe 1b according to the second embodiment configured as described above will be described.

  As shown in FIG. 5, when the shoe 1b is normally used, the tilting heel portion 21b is in a vertical state, and the height of the heel portion 4b is the highest. At this time, the locking plate 30 protrudes into the locking hole 33, and the tilting collar portion 21b cannot tilt. Therefore, even if the shoe 1b is worn and the weight is applied to the heel portion 4b, the tilting heel portion 21b does not tilt, so that the shoe 1b can be used as a shoe having a high heel.

  Further, when the tilting collar portion 21b is in the vertical state as described above, the connecting plate 5 is locked and the front portion of the shoe sole body 2 is pulled backward. And the attachment metal fitting 14 fixed to the front part base 3 is pulled back by the tension | tensile_strength of the connection board 5, and it is in the state which bent the recessed part 2a of the shoe sole main body 2. FIG. Further, the lower end of the heel portion 4b and the front bottom surface from the concave portion 2a of the shoe sole body 2 coincide with each other on the same plane.

  When the shoe 1b is worn and walked with the heel portion 4b raised in this way, the state in which the concave portion 2a of the shoe sole body 2 is further bent due to a change in the weight applied by the walking motion or the like continues. appear. That is, a change that further reduces the angle occurs from the angle at which the connecting plate 5 is bent and bent. However, the connecting plate 5 and the mounting bracket 14 are slidably mounted in the front-rear direction, and the long concave portion 9 is formed longer than the mounting bracket 14. Therefore, even when the state where the concave portion 2a of the sole body 2 is further bent occurs, the connecting plate 5 can slide further forward. Therefore, it is possible to prevent in advance the bending of the connecting plate 5 inside the sole body 2, the inability to move the connecting plate 5 due to deformation, the damage to the sole body 2, etc. caused by the inability to move the connecting plate 5. Is possible. Moreover, since it becomes possible to prevent the concave portion 2a from becoming undeformable, the user can walk without a sense of incongruity as with ordinary shoes.

When a disaster such as an earthquake occurs, the heel portion 4b is not suitable for blame activities such as running through the rubble or going down the stairs when the heel portion 4b is raised. It is better to use it lower. When lowering the heel portion 4b, the rear sole 25 of the shoe 1b is squeezed, the money is fitted into the sliding portion 32, and a force is applied to the money to rotate the shaft head 10b to the left or right. The shaft head 10b is indirectly rotated. Then, the locking plate 30 below the pivot shaft 31 rotates in the same direction and is stored in the semicircular hole 35, and the locking plate 30 does not protrude into the locking hole 33. 21b can be laid down. As shown in FIG. 6, when the tilting collar portion 21 is laid down forward, the attachment portion of the connection plate 5 moves forward to loosen the connection plate 5, and the bending of the concave portion 2 a of the sole body 2 is greatly increased. Can be made. Further, both convex portions 36 provided on both inner side surfaces of the collar body 22 are sandwiched between two concave portions 37 provided on both side surface portions of the tilting collar portion 21b. For this reason, even when the heel portion 4b is lowered, the tilting collar portion 21b is kept in the sideways state and can be used with the heel portion 4b lowered.
And the lower end of the heel part 4b of FIG. 6 and the front bottom face from the recessed part 2a of the shoe sole body 2 come to coincide with each other on the same plane, and the user can use the shoe 1b as a shoe with low heels. It becomes possible.

  Therefore, if the shoe 1b of this embodiment is used, in addition to the same effect as the first embodiment, unlike the shoe of the first embodiment, there are only two types of changes in the heel height and the bending of the sole body. The change in the heel height and the bending speed of the sole body can be made faster than the shoe of the first embodiment.

  Instead of the configuration of the present embodiment, another one may be used. For example, it is good also as a structure which prevents the tilting of the tilting collar part 21b by screwing the rotation axis | shaft rod 31 and the tilting collar part 21b shown in FIG.10 and FIG.11. Moreover, although the tilting collar part 21b tilts in the front-rear direction, it does not have to be precisely in the front-rear direction, and may be attached so as to tilt in a direction shifted in the left-right direction. Instead of the shaft head portion 10b and the sliding portion 32, the shaft head portion 10a and the knob portion 13 used in the first embodiment may be used.

[Third embodiment]
Hereinafter, the present invention is embodied in a shoe having a high heel part, generally called a high heel, and a structure of a shoe 1c having a function of changing the heel part height by attaching and detaching the heel part will be described with reference to FIGS.

  As shown in FIG. 10, a shoe 1 c is provided on a sole body 2 as a sole body, a front sole 3 provided on the upper surface of the sole body 2, and a heel part of the sole body 2.

  The shoe sole body 2 is made of a synthetic resin and is processed into a shape similar to the shape of a sole of a person when viewed from above, and its front bottom surface is flat, and the bottom surface of the cross-sectional shape of FIG. The arch is curved from the front to the rear. In the vicinity of the boundary between the flat portion and the curved portion, there is provided a concave portion 2a in which the thickness of the sole body 2 is formed in a thin concave shape in the lateral direction and functions as a bendable bending portion. Yes.

  The heel portion 4c is composed of a collar body 22 and a mounting collar 21c. The heel body 22 is made of synthetic resin or wooden, and is provided on the heel of the shoe sole body 2. And it is formed in the shape similar to an inverted cone, is the same three-dimensional shape as the upper part shape of the mounting hook part 21c in the up-down direction, and is provided with a support part 22c as an insertion part for inserting the mounting hook part 21c.

  As shown in FIG. 7, the mounting collar 21c has an upper portion formed in a three-dimensional shape that is the same shape as the support portion 22c, and is formed in a shape obtained by adding a shape similar to an inverted half cone to the lower portion. For this reason, the upper portion of the mounting flange portion 21c can be attached by being fitted into the support portion 22c.

  On the upper surface of the heel part of the sole body 2, a circular recess 7 is formed at the upper position of the support portion 22 c, and the through hole 8 is perpendicular to the upper surface of the sole body 2 at the center. It is formed in the direction. The through hole 8 is provided with a shaft head 10c having the same shape as the concave portion 7, and is provided with a rotating shaft rod 50 threaded at a predetermined pitch width. The pivot shaft 50 is attached to the sole body 2 with a nut 52 fitted therein, and is rotatable relative to the sole body 2. The shaft head 10c of the rotary shaft 50 is formed with a sliding portion 32 into which a coin can be fitted.

  As shown in FIG. 12, in the upper part of the mounting collar portion 21c, a screw hole 54 drilled downward is provided at a position where the rotating shaft rod 50 is located at the time of mounting, and by inserting the rotating shaft rod 50, The mounting collar 21c is detachably attached to the collar body 22. A part of the upper part of the collar part is cut out, and a pin 53 is provided vertically in that part. The pivot shaft 50, the screw hole 54, and the mounting flange 21c function as a height varying means.

  The shoe sole body 2 is formed with a long concave portion 9 that is long from the vicinity of the base of the toe worn on the shoe 1c to the vicinity of the concave portion 7 in the front-rear direction of the shoe 1c. A through hole 9a is formed in the side end portion so as to be inclined and penetrate in the rear direction. Further, the collar body 22 is provided with a connecting plate passage 24 formed so as to be inclined from the through hole 9a toward the front portion of the support portion 22c and connected to the through hole 9a.

  On the upper surface of the flat portion in front of the sole body 2, a front shoe sole 3 having the same shape as the upper surface of the flat portion of the sole body 2 is laid, and on the lower surface portion of the front shoe sole 3 is a plate-like shape. A mounting bracket 14 is attached. The mounting bracket 14 is formed with a columnar locking portion 14a projecting downward.

  As shown in FIG. 9, the connecting plate 5 is a thin plate having a thickness of 0.2 mm or less and is formed long in the front-rear direction of the shoe 1. As the material, special steel obtained by heat-treating JIS G3311 is used. By using this special steel, the connecting plate 5 is flexible and hardly deformed. A locking hole 5 a that is elongated in the front-rear direction of the shoe 1 is formed in the front portion of the connecting plate 5. A hole 5 b is formed in the rear portion of the connecting plate 5.

  The connecting plate 5 is disposed in the elongated recess 9 by fitting a locking ring 18 into a locking portion 14a that penetrates into the locking hole 5a, and is attached to the mounting bracket 14 so as to be slidable in the front-rear direction. The rear end of the connecting plate 5 provided with the holes 5b passes through the through holes 9a.

  The rear end portion of the connecting plate 5 is locked to the heel portion 4c by inserting the pin 53 into the hole 5b when the mounting collar portion 21c is attached to the collar body. For this reason, the connecting plate 5 is in tension and the front portion of the shoe sole body 2 is pulled backward. That is, the connecting plate 5 is tensioned and the mounting bracket 14 fixed to the front bottom base 3 is pulled backward to bend the concave portion 2 a of the shoe sole body 2. At this time, the lower end of the heel portion 4c and the front bottom surface from the concave portion 2a of the shoe sole body 2 coincide with each other on the same plane. The height of the heel portion 4c and the bending angle of the shoe sole body 2 at the concave portion 2a are adjusted by adjusting the position of the pin 53 attached to the mounting heel portion 21c in the front-rear direction or the length of the connecting plate 5. Is adjusted. Here, the connecting plate 5, the rotary shaft 50, the mounting bracket 14, the mounting flange 21c, and the pin 53 function as bending means.

  In the shoe sole body 2, a rear sole 25 is attached to the upper surface behind the front sole 3 so as to cover the concave portion 7 and the long concave portion 9. In the vicinity of the buttocks of the rear base 25, the rear base 25 rises upward so that the shaft head 10c can be rotated. Around the sole body 2, a front foot holding portion 26 that holds the front portion of the shoe 1 when the shoe 1 is worn and a rear foot holding portion 27 that holds the rear periphery from the side of the foot are provided. Yes. The front foot holding portion 26 and the rear foot holding portion 27 are connected to the left and right sides between the front foot holding portion 26 and the rear foot holding portion 27 and in the vicinity of the bent portion 2a of the sole body 2. A stretchable material portion 28 is interposed. The lower part of the expansion / contraction member 28 is formed in an arc shape, and is provided with an opening 28a for allowing air to easily enter and exit and to be bent at the concave portion 2a.

  Next, the operation and effect of the shoe 1c according to the third embodiment configured as described above will be described.

  As shown in FIG. 10, when the shoe 1c is normally used, the wearing heel portion 21c is in a vertical state, and the height of the heel portion 4c is the highest. Since the mounting flange 21c and the support 22c have the same shape, the mounting flange 21c is in a state of being supported by being fitted to the support 22a. Further, the rotary shaft 50 is fixed by being screwed into the screw hole 54, so that the mounting collar portion 21c cannot be detached from the support portion 22c. Therefore, there is no problem that the wearing heel part 21c is detached while the shoe 1c is in use.

  Further, when the mounting saddle portion 21c is mounted, the pin 53 is inserted into the hole 5b of the connecting plate 5, and the shoe sole body 2 is pulled backward by tensioning the connecting plate 5. That is, when the mounting bracket 14 fixed to the front sole 3 is pulled rearward by the connecting plate 5 and the concave portion 2a of the shoe sole body 2 is bent, the lower end of the heel portion 4c as shown in FIG. The front bottom surface coincides with the same plane from the recess 2 a of the shoe sole body 2.

  When walking with the shoe 1c in the state where the heel portion 4c is raised (the state shown in FIG. 10), the concave portion 2a of the shoe sole body 2 is further bent due to a change in the weight applied by walking motion or the like. The state to continue occurs. That is, a change that further reduces the angle occurs from the angle at which the relaxation plate 5 is tensioned and bent. However, the connecting plate 5 and the mounting bracket 14 are slidably mounted in the front-rear direction, and the long concave portion 9 is formed longer than the mounting bracket 14. Therefore, even when the concave portion 2a of the shoe sole body 2 is further bent, the connecting plate 5 can slide further forward. Therefore, it is possible to prevent the slack plate 5 from being bent inside the sole body 2 due to the inability of the connecting plate 5 to move forward, the inability to move the slack plate 5 due to deformation, damage to the sole body 2 and the like. Is possible. Moreover, it becomes possible to prevent the concave portion 2a from becoming undeformable, and the user can walk without a sense of incongruity as with ordinary shoes.

  When a disaster such as an earthquake occurs, it is not suitable for running or going down stairs with the heel portion 4c raised. Therefore, it is more suitable to make the heel part 4c low as shown in FIG. As shown in FIG. 2, when the rear base 25 of the shoe 1c is rolled up, money is fitted in the sliding portion 32, and the shaft head 10c is manually rotated counterclockwise, the rotating shaft 50 is also rotated counterclockwise. Thus, the mounting collar 21c gradually moves downward, and the pivot shaft 50 can be separated from the screw hole 54. Therefore, it becomes possible to pull out the mounting flange 21c downward. When the mounting collar portion 21c is pulled out, the pin 53 is pulled out from the hole 5b of the connecting plate 5, the connecting plate 5 is loosened, and the curved angle of the concave portion 2a of the sole body 2 can be increased. And as shown in FIG. 11, the heel part main body 22 and the bottom face of the shoe sole main body 2 ahead of the recessed part 2a can be matched on the same plane, and the shoe 1c can be used as a shoe with a low heel. It becomes.

  When increasing the heel portion 4c, the procedure is the reverse of the above. That is, the mounting heel portion 21 c is inserted into the support portion 22 c, and at this time, the concave portion 2 a of the shoe sole body 2 is bent and the pin 53 is inserted into the hole 5 b of the connecting plate 5. Then, when the rear base 25 of the shoe 1c is rolled, the money is fitted into the sliding portion 32, and the shaft head 10c is rotated to the right, the rotation shaft 50 is also rotated to the right and the rotation shaft 50 is inserted into the screw hole 54. The mounting collar 21c can be fixed to the collar main body 22 by screwing. And as shown in FIG. 10, the heel part main body 22 and the bottom face of the shoe sole main body 2 ahead of the recessed part 2a can be matched on the same plane, and the shoe 1c can be used as a shoe with a high heel. It becomes.

  Therefore, if the shoe 1c of the present embodiment is used, in addition to the effects of the first embodiment and the second embodiment, the mounting collar portion 21c can be detached, so that when the heel portion 4c is lowered, the shoe 1c is worn. Only the weight of the buttocks 21c is reduced, and the burden on the user can be reduced during walking. Since the structure of the height changing means can be simplified as compared with the first embodiment, the number of parts can be reduced, and further weight reduction can be achieved. In addition, a shoe with a high heel portion that does not form an arch portion cannot use a height varying means that expands and contracts or tilts the heel portion as in the first and second embodiments. However, it is possible to change the collar part low by separating the collar part using the height varying means of the present embodiment.

  Instead of the configuration of the present embodiment, another one can be used. For example, the mounting rod portion 21c can be attached and detached using the pivot shaft 31 of FIG. 8 used in the second embodiment. If it does in this way, detachment | attachment of the attaching collar part 21c will be attained only by rotating the rotating shaft stick 31 a little. Instead of the sliding portion 32 provided on the shaft head portion 10c, the knob portion 13 may be provided as in the first embodiment. Moreover, it can replace with the pin 53 for tensioning the connection board 5, and a thing of another type can also be used. That is, a key claw shape that swells to the left and right is formed at the end of the connecting plate 5, and a shape that locks the key claw when the mounting collar 21c is mounted is formed on the top of the mounting collar. You can also.
