Description

    The present invention relates to an insole for footwear, and more specifically, a reinforcing member is embedded and installed in a foot insole that enables propulsion-type rolling walking to increase the strength of the insole, thereby making rolling walking more stable. While walking or stopping, it acts as a buffer between the ground and the sole to improve the feeling of landing and distribute the user's weight evenly to reduce the fatigue of the foot The present invention relates to an insole for footwear that not only minimizes but also enhances the appearance by exposing a part of the reinforcing member to the outside of the footwear.

  Generally, footwear is worn to protect the foot area of the human body, and various forms of footwear are provided. In particular, the bottom part serves as a shoe sole to protect the body by reducing the impact during walking. It is like that.

  Footwear is divided into a crust part that largely surrounds the entire foot and a bottom material that is joined to the crust and protects the bottom surface of the sole, that is, a shoe sole, which is generally a sole cover and an insole. And underlay structure.

  The underlay is actually made of a material that has some rigidity as a part that directly touches the ground and resists friction. The insole is laminated on the upper surface of the underlay and is generally configured to provide a cushion. It is laminated on the upper surface of the insole as an element that directly touches the back.

  In the case of such footwear, lay an underlay on the inner bottom surface of the footwear to absorb the impact transmitted from the ground to the sole during walking, or rubber or foam sponge with excellent cushioning for the footwear base and heel The structure made of the above materials is known, and recently, an elastic body such as an air bag or a spring formed on a shoe sole to enhance the elastic effect is widely known.

  If the footwear sole is made of rubber or foam sponge as described above, or if an elastic restoring body such as an air bag or a spring is built in the footwear sole, it can perform only a simple shock absorbing function. When the walking path that comes in contact with the ground with an approximately circular arc shape from the pedestrian's heel to the toes is used as a standard, the conventional general footwear sole is a natural and efficient walking. There is a problem that it can hardly contribute to the aspect of carrying out.

  In particular, the number of people who enjoy outdoor activities has increased greatly recently due to the improvement of living standards and the spread of five-day work, so that people who enjoy outdoor activities can feel even better comfort. At the same time, the footwear is being developed in a functional footwear development business that makes it possible to contribute to health promotion simply by walking on the footwear, so that the wearer's knees and foot joints and soles are not forced. Manufacturing companies invest a great deal of time and effort.

  As various functions that can be applied to footwear as described above, a slip prevention function, an impact absorption function, an athlete's foot prevention and a foul odor removal function through ventilation are already being actively applied. There is also a functional footwear that allows natural and efficient propulsion walking (hereinafter referred to as 'rolling walking') as if walking on a flat surface.

  As described above, as an insole for enabling an impact dispersion function and rolling walking, an insole having a rolling walking function according to the applicant's prior patent registration No. 10-0884659 is known.

  The footwear insole pre-registered by the present applicant forms a buffer space on the upper surface of the insole, while forming a concave groove portion at a constant interval along the length direction at the bottom of the insole, In the buffer space, ribs are formed so as to protrude along the portions corresponding to the concave grooves, so that it is compressed and deformed in an arc shape along the walking path over the entire sole surface. Propulsive rolling walks were made.

  However, such a previously registered patent of the present applicant has a configuration in which a buffer space and a recessed groove portion are formed inside the insole of the footwear, and such a configuration has an arc shape along the walking path by the recessed groove portion during walking. Compressive deformation is made and propulsion type rolling walking is made, but excessive compression deformation is made by the concave groove part so that flexibility becomes very high, and this does not improve walking ability and safety rather. A problem occurred.

  The present invention has been devised in order to improve the conventional technical limitations as described above, and the footwear insole of the present invention is composed of an upper insole and a lower insole, and an outer space is provided between the upper and lower insoles. The lower insole is embedded and formed with an underlay piece on which the wing portion of the reinforcing member is seated, and the wing portion is formed on the bottom surface of the upper insole. A seating groove to be seated is formed.

  The foot insole of the present invention as described above gives appropriate rigidity so that excessive compression deformation is not performed by the reinforcing member when compression deformation is performed along the walking path during walking and propulsion type rolling walking is performed. Therefore, a technical problem is to make rolling walking more stable by suppressing flexibility.

  In addition, the insole of the present invention is designed to provide a cushioning action when the user walks while wearing the footwear or when the user is in a stopped state, thereby improving the landing feeling and uniforming the weight of the user. It is a technical problem to be able to disperse the foot to minimize the fatigue level of the foot.

  In addition, the present invention provides the entire footwear by changing the length of the wing portion or exposing the wing portion formed on the outside of the reinforcing member to the outside of the footwear, or by forming it with letters, figures, etc. The technical challenge is to improve the aesthetics of the product.

  The present invention comprises a foot insole made up of an upper insole and a lower insole, and a reinforcing member is embedded between the upper insole and the lower insole, and the reinforcing member has a sole-shaped reinforcement. The wings are formed on both sides of the plate so as to protrude at regular intervals, the ends of the wings are formed in a repetitive bending manner in the vertical direction, and the wings of the reinforcing member are arranged on both sides of the upper and lower insole. A seating groove and an underlay piece are formed, and the wing portion is exposed on a side surface of the insole.

  In another embodiment of the present invention, the wing portion is formed long on the crust side to improve balance maintenance during walking, and as another embodiment, the wing portion is a wing adjacent to the injection molding. It is characterized in that it is formed by letters or figures in cooperation with the portion, and as another embodiment, a space portion is formed in the width direction on the reinforcing plate of the reinforcing member.

  The footwear insole of the present invention is flexible by imparting an appropriate rigidity so that excessive compression deformation is not performed by the reinforcing member when compressive deformation is performed along the walking path during walking and propulsive rolling walking is performed. Suppressing sex can make rolling walking more stable, and if the user walks with footwear or is stopped, it acts as a buffer Not only can the landing feel be improved and the weight of the user can be evenly distributed to minimize the fatigue level of the foot, but also the wings formed on the outside of the reinforcing member are exposed to the outside of the footwear. Thus, by changing the length of the wing part or by forming it with characters, figures, etc., there is an effect of improving the aesthetics of the entire footwear.

  The contents of the present invention will be described in more detail with reference to the accompanying drawings as an embodiment.

  FIG. 1 is a side view showing an example of footwear to which an insole of the present invention is applied, FIG. 2 is a bottom view showing an example of footwear to which an insole of the present invention is applied, and FIG. FIG. 4 is a separated perspective view of an insole and a sole in accordance with an embodiment of the present invention, FIG. 4 is a side view of FIG. 3, and FIG. 5 is a side sectional view of the insole in a combined state according to the present invention. 6 is a cross-sectional view taken along the line AA in FIG. 5, and FIG. 7 is a cross-sectional view taken along the line BB in FIG.

  Referring to FIGS. 1 to 7, a footwear insole 3 according to the present invention is attached to the upper side of the sole 2 as one of the elements forming the shoe sole of the footwear 1. The reinforcing member 6 is embedded and installed between the upper insole 4 and the lower insole 5.

  The reinforcing member 6 is made of synthetic resin and is disposed between the upper insole 4 and the lower insole 5, and the reinforcing member 6 is formed with a reinforcing plate 7 in the middle. The part 8 is formed continuously and repeatedly.

  Each of the wings 8 protrudes separately and is pulled out from the reinforcing plate 7 so that the end thereof has elasticity.

  The reinforcing member 6 is installed in the form in which the end of the wing 8 is exposed on the side surface of the insole 3 while being embedded in the insole 3, but the end of the wing 8 is on the upper side or the lower side. It is constructed in a bent form, and comes to have stronger elasticity.

  In the drawing, the wings 8 are repeatedly formed on the upper side and the lower side. However, the wings 8 may be irregularly bent on the upper side or the lower side. The ribs 8 and the reinforcing plate 7 can be formed with extra ribs to increase the rigidity, and the ribs can be formed at the center or peripheral edge of each individual.

  Such a reinforcing member 6 is formed in a shape corresponding to the outline shape of the footwear insole 3 as a whole, and has a wing portion having a wider outline at the portion where the foot is crumpled.

  If the state in which the reinforcing member 6 is embedded in the insole 3 is observed closely, the reinforcing plate 7 is completely embedded in the insole 3, and the outer end portion of each wing portion 8 is in the insole 3. It becomes the form which is exposed to the side.

  The outer end portion of the wing portion 8 is bent upward or downward, but the wing portion 8a bent upward is formed in close contact with the lower end of the side surface of the upper insole 4. The wing portion 8b bent downward is configured to be in close contact so as to surround the upper end of the side surface of the lower insole 5.

  That is, the outer end portion of each wing portion 8 is formed so as to cover and cover the side surfaces of the upper insole 4 and the lower insole 5 and, when viewed from the side surface, is repeatedly projected up and down so as to project differently. become.

  In order to stably fix the wings 8 that protrude upward and downward as described above, the seating grooves that accommodate the ends of the wings 8a that are bent upward are formed on both side bottom surfaces of the upper insole 4. 11 is formed, and the wing part bent upward is adhered and fixed in a state of being seated in the seating groove 11.

  As a result, even if the footwear flows in an irregular direction when the footwear is worn, the wing portion 8a only moves elastically together with the insole and maintains a stable fixed state without leaving its own position. it can.

  The lower insole 5 can be formed with a seating groove in the same manner as the upper insole 4, but other embodiments are shown in the drawings. That is, on both side surfaces of the lower insole 5, the underlay pieces 12 are formed so as to be broken from the outside at positions corresponding to the wings 8 b that are bent downward.

  The underlay piece 12 is formed in a form having a free end like the wing portion 8 of the reinforcing member 6, and is bonded to the wing portion 8 b that is independently bent downward. Each of the bent wings 8b has an even more free elastic reaction.

  Thus, the upper wing part 8a has a free elastic reaction compared to the wing part 8a bent upward, so that the upper wing part 8a is worn by the wearer wearing the footwear. The lower insole 5 which covers the foot more stably, the lower insole 5 under the footwear is compressed and deformed along the walking path during walking by the underlay piece 12 to enable propulsive rolling walking, and the wings bent downward 8b provides safety during walking.

  On the other hand, the footwear insole 2 bonded to the lower side of the footsole insole 3 according to the present invention may be a normal one, but is formed in a form in which irregularities are continuously and repeatedly formed as shown in the drawings. be able to.

  That is, the concavo-convex portions that are repeatedly repeated and correspond to the concave portion 13 correspond to the wing portion 8b bent downward, and the underlay piece 12 of the lower insole 5 coupled to the wing portion 8b. Is bonded and fixed in correspondence with the recess 13 so that the wings 8b bent downward can more directly contact and react with the ground.

  Such an undersole configuration could be applied in various forms depending on the use and characteristics of the footwear and the form of the insole.

  The operation of the present invention configured as described above will be described below.

  After the foot insole 3 according to the present invention, that is, the upper insole 4 and the lower insole 5 are embedded and installed with the reinforcing member 6 as an adhesive to form the foot insole 3, the bottom of the lower insole 5 As shown in FIG. 1, the upper 2 of the upper insole 4 and the upper insole 4 are provided with a crust as shown in FIG. 1 to manufacture footwear.

  When the user wears such footwear, the user wears and secures it in the seating groove 11 of the upper insole 4 and surrounds the upper part of the footwear by the wing 8a bent upward. As a result, it comes to play a role of supporting the wearer's foot and to improve comfort and safety.

  As described above, when the user can walk while wearing footwear, the lower insole 5 and the upper insole 4 are compressed and deformed by the underlay piece 12 according to the walking path so that the propulsion type rolling walk is performed. At this time, the reinforcing member 6 gives appropriate rigidity so that the upper and lower insoles 4 and 5 are not subjected to excessive compressive deformation, and by suppressing flexibility, rolling and walking is more effective. It will be made stable.

  On the other hand, when the user walks while wearing footwear or is in a stopped state, the wing 8b bent to the lower side and the underlay piece 12 formed on the lower insole 5 have a buffering action. Thus, not only is the landing feeling improved, but also the user's weight is uniformly dispersed to minimize the degree of tiredness of the foot.

  8a to 8c are side views showing another embodiment to which an insole according to the present invention is applied.

  That is, FIG. 8a is a view in which the wing 8 bent upward on the reinforcing member 6 is formed long on the upper side to further maintain and improve the balance of the user's foot during walking. FIG. 8c shows a visual aesthetic feeling by forming letters or figures in cooperation with the adjacent wings 8 during the injection molding of the wings 8, and FIG. FIG. 8a to be formed and FIG. 8b to which characters or figures are formed are all applied so that balance maintenance and visual aesthetics can be obtained at the same time.

  9A and 9B are cross-sectional views of an insole for footwear to which another embodiment of the reinforcing member applied to the present invention is applied. A space 14 is formed in the reinforcing plate 7 of the reinforcing member 6 in the width direction. Thus, the weight is dispersed by the space portion 14 during walking.

  The present invention as described and illustrated above is not intended to be limited to the embodiments described above, but can be modified and implemented in various forms without departing from the spirit of the present invention. Let's go.

  For example, the wing portion of the reinforcing member should be able to be implemented in various forms as required, and the bent form and the corresponding insole configuration can be modified as much as necessary. Could be implemented in different forms.
