Description

  The present invention relates to footwear with high heel such as high heel shoes, high heel sandals, and high heel boots, and more particularly to a high heel footwear having a heel portion configured in a leaf spring shape that can be elastically deformed in the vertical direction.

  High-heeled footwear, such as high-heeled shoes (hereinafter also simply referred to as high-heeled shoes) and high-heeled sandals, is one of the essential items for women's fashion, especially in the hospitality industry such as clothes shop staff, career women, In occupations such as flight attendants, it is common to work with high heels.

  However, traditional high heels were originally designed for temporary use at places such as parties, giving priority to the beauty of standing and gait. It wasn't done.

  When walking with high heels, it is difficult to kick out with an ankle or toe, so you will be walking with your knees and hips, which not only leads to fatigue due to concentration of strain on these muscles. There were problems that caused instability during walking and the risk of falling.

  In addition, when walking on concrete road surfaces or stairs, a high-pitched impact sound is generated, and the impact is transmitted directly to the body, combined with the leg posture when wearing high heels, damaging joints and tendons. Was a cause of posture deterioration and joint pain.

  In order to solve such a problem, for example, in Patent Document 1, as shown in FIG. 13, a spring A3 is incorporated inside a high heel A2 of a high heel shoe A1, and the tip of the heel shaft A4 is elastically expanded and contracted. 14 to absorb the impact, and as shown in FIG. 14, the heel B2 of the high heel shoe B1 is connected to the sole of the high heel shoe B1 via the leaf spring element B3, and the impact is absorbed by the elastic deformation thereof. Furthermore, as shown in FIG. 15, a spring element C3 bent in an S-shape is provided at the lower part of the heel C2 of the high heel shoe C1 to thereby absorb an impact.

  In Patent Document 2, as shown in FIG. 16, a high heel D1 in which a blade D2 constituting a heel is attached to a shoe sole is proposed. The blade D2 is formed in a U shape having a smooth curved portion D3, and a portion above the curved portion D3 is fixed to the shoe sole side. Further, the lower surface of the curved portion D3 is a ground contact surface whose entire lower surface is flat, and the curved portion D3 is elastically deformed during walking to absorb the impact received from the walking surface.

Special table 2007-508867 gazette US Pat. No. 5,195,258

  In the high heel shoe A1 shown in FIG. 13 described above, since the spring A3 and the heel shaft A4 are incorporated in a narrow space in the heel A2, the heel shaft A4 is held elastically without rattling with respect to the heel A2. When an external force acts on the heel axis A4 from a direction perpendicular to the expansion / contraction direction, the frictional resistance increases and a smooth expansion / contraction operation may be hindered.

  In addition, even if foreign matter such as dust enters the gap between the heel A2 and the heel shaft A4, there is a possibility that the expansion and contraction operation of the heel shaft A4 may be hindered. Since A2 must be thickened, there is also a problem inferior in terms of design.

  In the high heel shoe B1 shown in FIG. 14, since the distance from the lower end of the heel B2 to the leaf spring element B3 is large, a reaction force acts on the lower end of the heel B2 from the walking surface in the front-rear direction and the left-right direction during walking. Then, the leaf spring element B3 is bent or twisted, and the heel B2 is likely to be staggered, and the walking motion may become unstable.

  When the leaf spring element B3 is bent and deformed in the vertical direction, the lower end of the heel B2 swings and displaces relative to the sole of the high heel shoe B1 with the point diagonally above the front as an instantaneous center. Sometimes, when the toe side portion of the shoe sole and the lower end of the heel B2 are simultaneously in contact with the walking surface, the relative displacement in the front-rear direction between the shoe sole and the heel portion 2 is restrained by friction with the walking surface. Therefore, there is a problem that the function of the leaf spring element B3 cannot be sufficiently exhibited.

  Further, in the high heel shoe C1 shown in FIG. 15, the spring element C3 bent in an S shape has a shape that easily deflects in the front-rear direction following a force applied in the front-rear direction from the ground contact surface. For this reason, the walking motion may become unstable.

  Further, in the high heel shoe D1 shown in FIG. 16, since the U-shaped blade D2 constituting the heel is elastically displaced in the vertical direction mainly only by the elastic deformation of the curved portion D3, the cushioning effect is poor. Further, the lower part of the curved portion D3 has a structure in which the entire lower surface thereof is grounded. Therefore, when the blade D2 is grounded at a position below the arch when walking on an uneven road surface or the like, not only a feeling of instability occurs but also the road surface. If pebbles, etc. have fallen on the ground, there is a risk of riding on it and slipping.

  Therefore, the present invention solves the problems of the prior art as described above, reduces noise during walking and impact transmitted to the body without impairing design, and realizes natural, comfortable and safe walking. The aim is to provide high heel footwear.

  The high heel footwear of the present invention provided for the above purpose is a high heel footwear having a heel portion configured in a leaf spring shape that can be elastically deformed in a vertical direction, and the heel portion is formed in a longitudinal direction thereof. A portion near the front end is buried and fixed in the sole of the footwear on the toe side from the arch portion of the bottom of the footwear, and a portion continuing to the rear of the fixed portion is exposed from the bottom of the foot and A curved portion that is gradually spaced rearward from the lower surface and warped upwardly in a side view in the lower side of the arch portion, and at a position directly below the rear end of the bottom of the bottom of the heel portion, A shock absorbing member that is grounded when walking or standing is attached.

  In the high heel footwear of the present invention, the upper surface in the vicinity of the rear end of the heel portion and the lower surface in the vicinity of the rear end of the bottom are connected by an auxiliary spring member that can be elastically deformed in a substantially vertical direction. It is desirable.

  In this case, the auxiliary spring member is further constituted by a substantially C-shaped leaf spring that is convexly curved forward, and the upper end of the auxiliary spring member is the rear end of the shank incorporated in the footwear bottom. It is desirable that the second shock absorbing member is incorporated in the connecting portion between the shank and the auxiliary spring member, and the heel portion and the auxiliary spring member are a single plate-shaped blank. It is also desirable that they are integrally formed.

  In the high heel footwear of the present invention, it is also desirable that a wedge-shaped member for limiting the amount of elastic deflection of the heel portion is incorporated between the bottom bottom surface of the footwear and the top surface of the heel portion.

  According to the high heel footwear according to the first aspect of the present invention, when walking, the height of the heel portion is displaced by about 2 cm to 3 cm due to elastic deformation of the heel portion, and the impact applied to the body during walking is absorbed. Thus, the burden on the leg joints, muscles, and tendons can be reduced.

  At this time, since the heel portion has a curved portion that warps upward in a side view below the arch portion of the footwear bottom, after the impact absorbing member on the lower surface of the heel has landed on the walking surface, As the bottom of the footwear approaches the walking surface, the effective length of the heel that can be deformed is shortened along with the bending, and as a result, the bending rigidity of the heel increases, resulting in a soft and comfortable cushioning effect. It is done.

  Further, when the heel part moves away from the walking surface, the elastic restoring force acts so as to push the heel side of the shoe sole forward and obliquely upward, thereby effectively assisting the kicking of the foot. At this time, the heel portion has a large elastic restoring force only at the beginning of kicking out with a large deflection, and thereafter decreases rapidly as the effective length capable of bending deformation increases, so that the kicking operation can be performed smoothly. , You can walk smoothly and comfortably as if you were wearing athletic shoes.

  Furthermore, because the lower part of the heel part is curved upward, there is a risk that walking will be unstable due to unevenness such as stone pavement, or pebbles falling on the road will step on the arch and slide down Can be avoided, and even when maintaining a stationary standing posture, the leg muscles can be prevented from being stiffened by the cushion effect of the heel portion, so that fatigue can be reduced.

  In addition, the high-heeled noise that occurs when walking on steep concrete road surfaces and stairs with conventional high heel shoes, the soundproof effect of the shock absorbing member attached to the lower surface of the rear end of the heel part, and the heel part It can be greatly reduced by a synergistic effect with the cushioning effect.

  According to the high heel footwear according to the invention described in claim 2, since the bending moment applied to the connecting portion between the front end portion of the heel portion and the shoe sole is reduced by the auxiliary spring member, the durability of the connecting portion is reduced. Since a soft leaf spring can be used for the heel portion, the cushioning property can be improved.

  According to the high heel footwear according to the invention described in claim 3, since the auxiliary spring member is configured by a substantially C-shaped leaf spring in a side view, it is possible to prevent torsional deformation of the heel portion, and during walking The stability of the can be further increased.

  In addition, since the upper end portion of the auxiliary spring member is connected and fixed to the rear end portion of the shank incorporated in the footwear bottom portion, the auxiliary spring member can be stably and firmly fixed to the shoe sole. Moreover, since the 2nd impact absorption member is incorporated in the connection part of a shank and an auxiliary spring member, the impact transmitted through an auxiliary spring member from a heel part to a shoe sole can be absorbed effectively.

  According to the high heel footwear according to the invention described in claim 4, since the heel portion and the auxiliary spring member are integrally formed from a single plate blank, the number of parts can be reduced and the durability can be increased. At the same time, the manufacturing cost can be reduced. Furthermore, since there are no connecting parts such as mounting screws between the auxiliary spring member and the heel portion, and both are continuous with a smooth curved surface, the design can be enhanced.

  According to the high heel footwear according to the invention described in claim 5, the amount of sinking on the heel side of the footwear can be individually adjusted according to preference when walking or standing.

The buffer plate 5 is bonded and fixed. The buffer plate 5 is formed of a thin plate-like high-friction hard rubber, and absorbs noise and impact generated when walking on a hard road surface such as concrete or stairs and plays a role of making it difficult to slip. It is an important member, and is disposed at a position substantially directly below the rear end portion of the upper outsole 4A.

  Between the upper surface in the vicinity of the rear end portion of the heel portion 3 and the lower surface in the vicinity of the rear end portion of the upper outsole 4A, a leaf spring having a substantially C-shape in a side view curved in a convex shape forward is formed. An auxiliary spring member 6 is incorporated. The auxiliary spring member 6 is made of a stainless steel plate for springs similar to the heel portion 3, and as shown in FIG. 5, a mounting hole 6A is formed at the lower end thereof.

  On the other hand, a screw hole 3D is formed near the rear end 3C of the heel portion 3 at a position facing the mounting hole 6A, and the mounting screw 7 is threaded into the screw hole 3D through the mounting hole 6A. Thus, the auxiliary spring member 6 is fixed to the heel portion 3.

  Although not shown in detail, the mounting screw 7 is formed with a hexagonal hole for inserting a hexagonal wrench in its head and has a length that does not protrude from the lower surface of the heel portion 3. Has a part. Further, the lower end of the screw hole 3D is closed by the buffer plate 5 fixed to the lower surface of the heel portion 3 with an adhesive.

  Next, FIG. 6 is a partial cross-sectional view in the vicinity of the upper end of the auxiliary spring member 6. FIG. 6 (a) shows a state assembled to the shoe sole, and FIG. 6 (b) shows an exploded state. As shown in FIG. 2B, a pair of mounting holes 6B are formed in the upper end portion of the auxiliary spring member 6 so as to allow the stepped mounting screws 8 to pass therethrough in the longitudinal direction.

  On the other hand, a rectangular hole 4C is formed in the vicinity of the rear end portion of the upper main bottom 4A, and an impact absorbing block 9 as a second impact absorbing member is disposed inside the rectangular hole 4C. The shock absorbing block 9 is made of a flat rectangular rubber material that fits the inner surface of the rectangular hole 4C, and its thickness slightly exceeds the thickness of the upper bottom 4A when no external force is applied. Yes. The shock absorbing block 9 is formed with through-holes 9A having substantially the same diameter as those of the pair of mounting holes 6B.

  As shown in FIG. 6A, the upper surface of the shock absorbing block 9 is in contact with the lower surface of the rear end portion 11A of the shank 11 embedded in the rear midsole 10, and the auxiliary spring member 6 The upper end portion and the rear end portion 11A are coupled to each other by a pair of stepped mounting screws 8 with an impact absorbing block 9 interposed therebetween.

  The rear midsole 10 is made of a paper material impregnated with resin, and is fixed to the upper surface of the upper main bottom 4A in a range from the arch to the heel of the inner bottom portion of the upper 2. Further, as shown in FIG. 5, a cloth front insole 12 is fixed to the upper surface of the upper outsole 4A continuously in front of the rear insole 10, and further, the rear insole 10 and the front part An insole 13 is provided on the insole 12 so as to be removable.

  Further, as shown in FIG. 6, each of the pair of stepped mounting screws 8 has a head 8A in which a hexagonal hole for inserting a hexagonal wrench is formed, like the mounting screw 7 described above. And a short cylindrical large-diameter portion 8B and a screw portion 8C.

  The large-diameter portion 8B has an outer diameter that matches the inner diameter of the mounting hole 6B of the auxiliary spring member 6 and the through-hole 9 of the shock absorbing block 9, and its length is not subjected to compressive force. The thickness of the shock absorbing block 9 and the thickness of the auxiliary spring member 6 are slightly shorter than the total thickness, and the length of the screw portion 8C is less than the thickness of the rear end portion 11A of the shank 11. Has been.

  Further, as shown in FIG. 6B, the rear end portion 11A of the shank 11 is formed with screw holes 11B for screwing the screw portions 8C of the respective mounting screws 8, as shown in FIGS. As shown in (a), in the state where each mounting screw 8 is screwed and fixed in these screw holes 11B until the end surface of the large diameter portion 8C contacts the lower surface of the rear end portion 11A, the shock absorbing block 9 is The upper and lower surfaces are elastically compressed in the thickness direction so that the lower surface of the rear end portion 11A and the upper surface of the rear end portion of the auxiliary spring member 6 are in close contact with each other to absorb the shock transmitted from the auxiliary spring member 6 to the shoe sole side. Demonstrate the function to do.

  Next, each process of the walking motion by the high heel 1 configured as described above will be described with reference to FIG. FIG. 2A shows a moment when the lower surface of the buffer plate 5 attached to the heel portion 3 of the foot-side high heel 1 that has stepped on touches a walking surface such as a road surface.

  At this moment, the heel portion 3 and the auxiliary spring member 6 are not yet deformed flexibly, and these portions are in the process of approaching the walking surface together with the upper 2 as the foot is stepped on. In this process, the lower surface of the buffer plate 5 first hits the walking surface, but the collision sound generated at that time is absorbed by the buffer plate 5, so no noise during walking like conventional high heels is generated. .

  Next, as shown in FIG. 6B, in the process in which the upper 2 further approaches the walking surface together with the foot, the rear end portion of the heel portion 3 receives an upward reaction force from the walking surface via the buffer plate 5, As a result, the rear end side of the heel portion 3 is elastically deformed upward relative to the upper 2, and at the same time, the auxiliary spring member 6 is also elastically deformed and deformed to obtain a cushioning effect. The part 3 and the auxiliary spring member 6 store elastic energy corresponding to the amount of bending deformation.

  Note that the effective length of the heel portion 3 from the front end vicinity portion 3A shown in FIG. As a result, since the bending rigidity (bending rigidity) of the heel portion 3 is increased, a soft and comfortable cushion effect can be obtained.

  Furthermore, as shown in FIG. 7C, when the point P1 in front of the shoe sole of the high heel 1 comes in contact with the walking motion, a part of the load applied to the rear end side of the heel portion 3 moves to the point P1 side. Therefore, the load burden on the heel portion 3 is reduced. Then, each of the heel portion 3 and the auxiliary spring member 6 tries to return to the original shape by an elastic restoring force.

  On the other hand, the contact point between the high heel 1 and the walking surface of the shoe sole continuously moves from the point P1 to the point P2 on the toe side as shown in FIG. The elastic restoring force of 3 and the auxiliary spring member 6 acts so as to push the heel side of the shoe sole forward and obliquely upward, thereby releasing the elastic energy accumulated therein and assisting the walking motion.

  The walking operation after the heel portion 3 and the auxiliary spring member 6 are elastically returned to the original positions and the buffer plate 5 is detached from the walking surface is the same as a normal high heel, as shown in FIG. The point P3 at the tip of the shoe sole finally leaves the walking surface.

  In addition, in embodiment mentioned above, although the side view substantially C-shaped auxiliary | assistant spring member 6 is used, the form of an auxiliary | assistant spring member is not limited to this, It comprises with a compression coil spring or a bamboo shoot spring. Is also possible. However, in order to stabilize the movement of the heel portion, it is desirable to configure the spring with a shape that is difficult to deform in the lateral direction, for example, a leaf spring that is curved in a V shape or S shape in a side view.

  Further, the high heel 1 ′ shown in FIG. 8 as the second embodiment of the high heel footwear according to the present invention limits the amount of elastic deflection of the heel portion 3 between the lower surface of the upper bottom 4A and the upper surface of the heel portion 3. The wedge-shaped member 14 is incorporated, and in the same figure, the portions denoted by the same reference numerals as in FIG. 1 have the same structure as the high heel 1 described above.

  In the present embodiment, the wedge-shaped member 14 is formed of hard rubber, and one side surface thereof is fixed to the bottom 4 side, and the other one side surface of the heel portion 3 is unloaded. Opposite the top surface with a slight gap.

  When a load is applied to the heel side of the high heel 1 ′ and the heel portion 3 is elastically deformed by a predetermined amount, the upper surface of the heel portion 3 comes into contact with the wedge-shaped member 14. As a result, since the length of the heel portion 3 that can be substantially deformed is shortened, the apparent spring constant in the elastic deformation of the heel portion 3 is increased after the contact, and the heel portion 3 is less likely to bend. The displacement to can be suppressed. By changing the gap or selecting the hardness of the rubber used for the wedge-shaped member 14, the amount of sinking on the heel side when the high heel 1 'is worn can be individually adjusted according to preference.

  Next, as a third embodiment of the high heel footwear according to the present invention, a high heel 1a shown in FIG. 9 is formed by integrally forming a heel portion 3a and an auxiliary spring member 6a from a single stainless steel plate blank. The central portion of the rear half of the heel portion 3a is cut and raised in a substantially C shape in a side view to form an auxiliary spring member 6a.

  Other portions of the high heel 1a of the present embodiment are the same as those of the high heel 1 of the previous embodiment. In the figure, the portions denoted by the same reference numerals as those in FIG. In the high heel 1a shown in FIG. 9, since the auxiliary spring member 6a can be integrally manufactured from the same blank as the heel portion 3a, the number of parts can be reduced, the durability can be increased, and the manufacturing cost can be reduced. There is. Moreover, since the heel part 3a and the auxiliary spring member 6a are continuous with a smooth curved surface, the design is excellent.

  Further, a high heel 1b shown in FIG. 10 as a fourth embodiment of the high heel footwear according to the present invention is formed by cutting and raising both outer sides of the rear half of the heel portion 3b into a belt shape to form an auxiliary spring member 6b. Further, a high heel 1c shown in FIG. 11 as a fifth embodiment of the high heel footwear according to the present invention is formed by cutting and raising one side of the rear half of the heel portion 3c into a belt shape to form an auxiliary spring member 6c.

  Further, a high heel 1d shown in FIG. 12 as a sixth embodiment of the high heel footwear according to the present invention is obtained by omitting the auxiliary spring member 6 from the high heel 1 shown in FIGS. 1 to 5 described above. In addition, since the high heel 1d shown in FIG. 12 needs to receive the load which acts on the heel side of the high heel 1d only by the heel part 3d, the bending rigidity of the heel part 3d is higher than the thing of each embodiment mentioned above. .

  In the embodiments described above, spring stainless steel (for example, SUS304) is used as the material for the heel portion and the auxiliary spring member, but these materials are not limited to stainless steel. For example, a metal material that can be elastically deformed greatly, such as spring steel subjected to rust prevention treatment by chrome plating or the like, may be used.

  These materials include non-metallic materials such as GFRP (glass fiber reinforced resin) and CFRP (carbon fiber reinforced resin), metals and resins to reduce weight and reduce vibration and noise generated during walking. A laminated composite material may be used.

  In addition, the heel part and auxiliary spring member are configured by laminating a plurality of thin plates in the shape of a laminated leaf spring like a leaf spring structure used for holding the axle of an automobile, and the sliding friction resistance between adjacent plates is increased. You may comprise so that a vibration damping effect may be acquired using.

  The high-heeled footwear of the present invention can be widely used for high-heeled footwear in general, including women's high-heeled shoes, high-heeled sandals, and high-heeled boots, as well as those for men.
