Like this, the second binding portion 20 is formed with holding holes 22 to hold the upper portion of the shoes 1 and it is inserted with the end of the shoelaces L passed through the final connecting hook C of the shoes 1 so as to maintain union of the shoelaces L. As shown, the binding portion 20 is composed of a body 21 formed with a guiding space 23 into which the shoelaces L are inserted and a guiding bar 24 provided in the guiding space 23 to be horizontally movable.
Herein, the body 21, as shown in
Meanwhile, the guiding bar 24 is provided to have its section including a circle, a polygon (a triangle, a quadrangle, a pentagon, a hexagon etc.) or an oval.
In the second binding portion 20, the front end of the shoelaces L is inserted in the guiding space 23 and covers the outer periphery surface of the guiding space 24, and then the end of the shoelaces L is drawn out to the direction in which the shoelaces L is inserted. And, when the end of the shoelaces L is pulled out, as shown
That is, as shown in
As shown, the binding portion 30 is to bind the shoelaces L on the middle portion of the instep of the shoes 1. The binding portion 30 includes a body 31 forming outer body, and it is a board type and formed with an inner space 31 therein. The body 31 is formed with inserting holes 33 into which each end of the shoelaces L is inserted on the both sides thereof, and formed with a pair of direction changing protrusions 32 to downwardly guide and to upwardly rotate the shoelaces L inserted through the inserting holes 33. And, the body 31 is formed with an exit 34 on the upper portion thereof such that the shoelaces L rotated on the direction changing protrusions 32 is upwardly drawn out.
In the binding portion 30, the end of the shoelaces L is respectively inserted in the both sides of the body 31, and the inserted shoelaces L are rotated on the pair of direction changing protrusions 32 formed in the lower of the body 31 to have a determined space such that the end thereof faces to the upper side. And, each end of the shoelaces L rotated on the direction changing protrusions 32 is outwardly drawn out through the exit 34 formed on the upper side of the body 31, and as shown, it is connected to the connecting hook C provided in the shoes 1. The third binding portion 30 closely holds the lower end of the shoelaces L. That is, the binding condition is enhanced by upwardly pulling out the shoelaces L passed through the third binding portion 30, the binding condition is maintained by going to left and right sides, and the binding condition is released by lifting the end portion of the body 31. That is, the union is maintained when the shoelaces L are in a condition shown in solid lines, and the union is enhanced when the shoelaces L are in a condition shown in dotted lines.
The operation of the device for binding shoelaces according to the present invention is explained as follows.
Firstly, the first binding portion 10, the second binding portion 20 and the third binding portion 30 are connected to the shoelaces L which are crossly bond on the instep of the shoes 1. The third binding portion 10, the first binding portion 10 and the second binding portion 20 are respectively provided on the lower portion, the middle or upper portion and the portion where the end of the shoelaces L passes.
The structure of the first binding portion 10 and the second binding portion 20 is almost identical with the prior art of the present applicant, and therefore they are not explained in detail. Further, the third binding portion 30 is also afore explained with reference to
The shoelaces L on the instep of the shoes 1 is adjusted in its tightening force using the first binding portion 10.
Firstly, the receiving member 11 and the binding member 13 are positioned to be fitted from each other. That is, after positioning the hooking plate 13a of the binding member 13 to be inserted in the slot 11b of the receiving member 11, the receiving member 11 and the binding member 13 are assembled by fittings. And then, the hooking plate 13a of the binding member 13 enters into the slot 11b, and the pressing plate 12a of the adjusting member 12 installed in the installing recess 11c of the receiving member 11 is returned to initial position by the magnetic body 14. As a result, the stopper 12d formed on the other side of the pressing plate 12a is hooked in the hooking recess 13b of the hooking plate 13a. Therefore, the connection force between the receiving member 11 and the binding member 13 is created.
At this condition, to release the connection between the receiving member 11 and the binding member 13, the pressing plate 12a installed in the installing recess 11c of the receiving member 11 is pressed. Then, one side of the pressing plate 12a is pressed and the other side thereof is upwardly rotated against the hinge shaft 12b. At this time, the stopper 12d downwardly protruded on the other side is separated from the hooking recess 13b of the binding member 13, and then the connection force is released. At this condition, the binding member 13 is pulled and then separated from the receiving member 11.
The second binding portion 20 is to maintain and release the binding of the end of the shoelaces L. The front end of the shoelaces L is inserted in the guiding space 23, and it covers the outer periphery of the guiding bar 24 vertically provided therein, and then the end of the shoelaces L is drawn out to the direction in which the shoelaces L is entered.
At this condition, if the end of the shoelaces L is pulled, one end of the shoelaces L presses the side of the guiding bar 24 which is horizontally moved and also the upper portion thereof presses the lower portion thereof, and therefore the close connection is maintained without sliding. To release this close connection, the other side of the shoelaces L, that is, one end of the shoelaces L which enters toward the second binding portion 20 is upwardly pulled.
Finally, the third binding portion 30 has a symmetrical figure in left and right. Each end of the shoelaces L is inserted in the third binding portion 30 at its side and it is downwardly passed, and then it is upwardly pulled out, and therefore the close connection of the shoelaces L is adjusted.
The third binding portion 30 is inserted with each end of the shoelaces L through the inserting holes 33 formed on the both sides of the body 31. Each end of the inserted shoelaces L is rotated on the outer periphery surface of the direction changing protrusions 32 and then guided toward the upper side thereof. And, it is outwardly drawn out through the exit 34 formed on the upper portion of the body 31. The drawn end of the shoelaces L is connected to the connection hook C near to the upper portion of the third binding portion 30, and the binding condition is enhanced by upwardly pulling out the shoelaces L passed through the third binding portion 30, the binding condition is maintained by going to left and right sides, and the binding condition is released by lifting the end portion of the body 31.
As shown like this, the device for binding shoelaces according to the present invention is applied to running shoes or mountain-climbing boots provided with a plurality of hook rings oppositely fixed on both sides of the open portion of the instep thereof with constant interval and in which shoelaces L crossly pass through the hook rings and then are bound. The device includes a first binding portion 10 to selectively release the binding condition of the shoelaces L with the operation force of a user, a second binding portion 20 formed with holding holes 22 to be positioned over the instep of the shoes and in which the end of the shoelaces L passed through the final hook ring C of the shoes 1 is inserted into the holding holes 22 to maintain the binding condition, and a third binding portion 30 to bind the shoelaces L positioned at the middle of the instep of the shoes 1 and to adjust the binding against the lower portion of the instep of the shoes 1.
This structure is almost identical with the prior art of the present applicant. But the present invention is to improve the structures of the first, second and third binding portions 10, 20 and 30 to enhance the reliability in operation and the convenience in use. Hereinafter, the first binding portion 10 according to a first preferred embodiment of the present invention will be explained.
The binding portion 10 is composed of a receiving member 11 which is a female member, a binding member 13 which is a male member and fitted into the receiving member 11, and an adjusting member 12 rotatably provided on the receiving member 11 and selectively raising binding force against the binding member 13.
The receiving member 11 is formed with an opened slot 11b at one side thereof into which a clutching plate 13a of the binding member 13 can be inserted. A magnetic body 14 is attached on one side of the slot 11b, specifically, on the inner upper side surface of the slot 11b in the drawings so that a pressing plate 12a of the adjusting member 12 can be maintained in attached condition by the magnetic force. And, the receiving member 11 is formed with an installing recess 11c on the upper surface thereof to be installed with the adjusting member 12 which is an element to be given with the pressing force of the user, and the installing recess 11c is connected to the slot 11b. Also, the receiving member 11 is formed with a hinge recess 11d to mutually face toward the side wall of the installing recess 11c, and a hinge shaft 12b protruded on both sides of the pressing plate 12a constituting the adjusting member 12 is rotatably fitted in the hinge recess 11d.
Meanwhile, the receiving member 11 is formed with a supporting piece 11a to be protruded at the other side opposing to the slot 11b, and the supporting piece 11a is formed with a through hole 11a which binds the shoelaces L. The supporting piece 11a can be revised with various shapes if it can connect the shoelaces L, and in this embodiment, a pairs of supporting pieces 11a are prudently formed. And, the pairs of supporting pieces 11a has a narrower portion at the front portion of the shoes 1 and a wider portion at the instep of the shoes 1, and the wider portion is longer than the narrower portion.
The binding member 13 is inserted in the slot 11b of the receiving member 11 to be selectively clutched and therefore to maintain or release the binding condition therebetween, and it is provided with a clutching plate 13a formed with a clutching recess 13b in the longitudinal direction on one side, that the upper side surface in the drawing. The binding member 13 is prudently provided with a supporting piece 13c on the other side opposite to the clutching plate 13a, and the supporting piece 13c is formed with a through hole 13c′ to bind the shoelaces L. And, the binding member 13 is corresponded with the supporting piece 11a of the receiving member 11.
The adjusting member 12 is a board type to partially cover the installing recess 11c, and it includes a pressing plate 12a being rotatably installed in the installing recess 11c to be selectively attached to the magnetic body 14 and being received the pressing force from the user, a stopper 12d being downwardly protruded to be selectively clutched to the clutching recess 13b. The stopper 12d is upwardly rotated with respect to the hinge shaft 12b when the pressing plate 12a is rotated, that is it is pressed by the pressing force of the user, and therefore it is separated from the clutching recess 13b of the binding member 13. Further, the adjusting member 12 is provided with an elastic plate 12t extended from the pressing plate 12a, and the elastic plate 12t is formed with a clutch jaw 12t′ on the end thereof. Herein, the elastic plate 12t, as shown in
With this structure, when the pressing plate 12a is pressed, it is rotated with respect to the hinge shaft 12b, and finally the stopper 12d is separated from the clutching recess 13b. When the pressing plate 12a is released, the stopper 12d is clutched in the clutching recess 13b by being elastically clutched the clutch jaw 12f of the elastic plate 12t in the installing recess 11c of the binding member 13.
The reference number 12e which is not explained is a board typed member which is extended to the other side of the pressing plate 12a, that is, the opposite direction of the elastic plate 12t, as shown, indicates an extended plate 12e to prevent the other end of the pressing plate 12a from being upwardly rotated by being clutched to the inner wall of the installing recess 11c.
In the first binding portion 10, when the receiving member 11 and the binding member 13 are fitted from each other, the clutch jaw 12t′ of the adjusting member 12 is elastically clutched to one side of the installing recess 11c. At this condition, one end of the adjusting member 12 is upwardly rotated such that the elastic plate 12t of the adjusting member 12 blocks the installing recess 11c and the stopper 12d is still clutched into the clutching recess 13b of the binding member 13. Therefore, it is maintained that the receiving member 11 and the binding member 13 are connected from each other.
With this condition, when the pressing plate 12a of the adjusting member 12 installed on the recessing recess 11c of the receiving member 11, one side of the pressing plate 12a is downwardly rotated with respect to the hinge shaft 12b. At this time, the elastic plate 12t and the clutch jaw 12t′ are intended to be upwardly rotated, but the clutch jaw 12t′ is elastically changed since it is clutched to one side wall of the installing recess 11c. The stopper 12d provided on one side of the elastic plate 12t is separated from the clutch recess 13b of the binding member 13, and therefore finally the union between the receiving member 11 and the binding member 13 is released.
Therefore, the receiving member 11 is completely released from the binding member 13 by their separation.
As shown in the Figures, the first binding portion 10 is composed of a receiving member 11 which is a female member, a binding member 13 which is a male member and fitted into the receiving member 11, and an adjusting member 12 rotatably provided on the receiving member 11 and selectively raising binding force against the binding member 13. The first binding portion 10 is similar to the afore-mentioned first binding portion, and therefore it is given same reference number for its same elements, and any detailed description will be omitted.
In this embodiment, the first binding portion 10 is an elastic member 15 for returning when the pressing for the adjusting member 12 is released. It includes a upper plate 15a which is exposed toward one side of the installing recess 11c and has both cut side and a supporting plate 15b which is contacted with one side of the stopper 12d by the downwardly extended upper plate 15a.
With this structure, if the pressing plate 12a is pressed, the stopper 12d is separated from the clutch recess 13b by its rotation for the hinge shaft 12b, and therefore the union between the receiving member 11 and the binding member 13 is released. At this time, the other side of the pressing plate 12a, that is one side of the stopper 12d is supported by a vertical plate 15b of the elastic member 15, and the vertical plate 15b is elastically changed by the rotation of the stopper 12d.
Under this condition, if the pressure given to the pressing plate 12a is released, the vertical plate 15b is elastically returned, and then the stopper 12d and the pressing plate 12a are returned to its original position. In this process, the stopper 12d is clutched to the clutch recess 13b in a case that the binding member 13 is inserted in the receiving member 11.
In this embodiment, the first binding portion 10 is an elastic member 16 for returning when the pressing for the adjusting member 12 is released. It is suggested that a steel wire spring is used is used as the first binding portion 10. The steel wire spring has both ends fixedly connected to both sides of the pressing plate 12a, and one end clutched to one inner wall of the installing recess 11c of the binding member 13.
With this structure, if the pressing plate 12a is pressed, the stopper 12d is separated from the clutch recess 13b by its rotation for the hinge shaft 12b, and therefore the union between the receiving member 11 and the binding member 13 is released. At this time, the elastic member 16 disposed on the other side of the pressing plate 12a is elastically changed during the rotation of the pressing plate 12a since its end is supported by the one inner wall of the installing recess 11c.
Under this condition, if the pressure given to the pressing plate 12a is released, the pressing plate 12a is returned to its original position by the elastic return of the elastic member 16 which is a steel spring. In this process, the stopper 12d is clutched to the clutch recess 13b in a case that the binding member 13 is inserted in the receiving member 11.
In this embodiment, the first binding portion 10 is an elastic member 17 for returning when the pressing for the adjusting member 12 is released. It is suggested that a torsion spring is used is used as the first binding portion 10. The torsion spring has one end which is wound and supported to the hinge shaft 12b prudently formed on both sides of the pressing plate 12a and the other end which is clutched to one inner wall of the installing recess 11c of the binding member 13.
The pressing plate 12a is elastically returned to its original position by the adjusting member 12 provided with the elastic member 17 which is a torsion spring through the same operation as that of the third embodiment.
In this embodiment, the first binding portion 10 is an elastic member 18 for returning when the pressing for the adjusting member 12 is released. It is suggested that a coil spring is used as the first binding portion 10.
The elastic member 18 which is a coil spring has one end connected to one side of the pressing plate 12a and the other end connected to one side of the binding member 13. When the pressing plate 12a is rotated by pressure, the coil spring is expanded and then elastic force is saved. If the pressure is removed, the pressing plate 12a is returned to its original position by the saved elastic force.
Like this, the second binding portion 20 is formed with holding holes 22 to hold the upper portion of the shoes 1 and it is inserted with the end of the shoelaces L passed through the final connecting hook C of the shoes 1 so as to maintain union of the shoelaces L. As shown, the binding portion 20 is composed of a body 21 formed with a guiding space 23 into which the shoelaces L are inserted, a guiding bar 24 provided in the guiding space 23 to be horizontally movable, and a first and second posts 25 and 26.
Herein, the body 21 is formed with a upper plate 21a and a lower plate 21b which are disposed with a distance to prepare the guiding space 23 on one side of the holding holes 22, and the guiding space 23 is formed with the guiding bar 24 horizontally movably provided and the first and second posts 25 and 26 disposed with a predetermined distance on one side of the guiding bar 24.
Meanwhile, the guiding bar 24 is integrally formed with a guiding piece 24′ which is inserted in the rail recesses 23′ formed on the opposite sides of the upper and lower plates 21a and 21b to obstruct the rotation of the guiding bar 24 and to be safely slidably moved. And, the guiding bar 24 is provided to have its section including a circle, a polygon (a triangle, a quadrangle, a pentagon, a hexagon etc.) or an oval.
In the second binding portion 20, the front end of the shoelaces L is inserted in the guiding space 23 and rotates the guiding bar 24, and then it enters into the space between the guiding bar 24 and the first post 25. Subsequently, it enters into the space between the first post 25 and the second post 26, and the end of the shoelaces L is pulled. At this time, it moves to one side of the guiding bar 24 and presses one end of the shoelaces L, and then the upper end of the shoelaces L also presses the lower of the shoelaces L so as to maintain union.
As shown, the binding portion 30 is to bind the shoelaces L on the middle portion of the instep of the shoes 1. The binding portion 30 includes a body 31′ forming outer body, and it is a board type and formed with an inner space 31′ therein. The body 31′ is formed with a pair of inserting holes 33′ into which each end of the shoelaces L is entered and come out on the both sides thereof, and formed with a pair of direction changing protrusions 32′ which are vertically formed in the body 31′ with a distance and support the inserted shoelaces L so as to be drawn out after rotated.
In the binding portion 30, the end of the shoelaces L is respectively inserted in through the exit 33′ formed on the both sides of the body 31, and the inserted shoelaces L are rotated on the pair of direction changing protrusions 32′ formed in the lower of the body 31 to have a determined space such that the end thereof faces to the upper side. And, each end of the shoelaces L rotated on the direction changing protrusions 32 is outwardly drawn out through the exit 34 formed on the upper side of the body 31, and as shown, it is connected to the connecting hook C provided in the shoes 1. The third binding portion 30 closely holds the lower end of the shoelaces L. That is, the binding condition is enhanced by upwardly pulling out the shoelaces L passed through the third binding portion 30, the binding condition is maintained by going to left and right sides, and the binding condition is released by lifting the end portion of the body 31.
The operation of the device for binding shoelaces according to the present invention is explained as follows.
Firstly, the first binding portion 10, the second binding portion 20 and the third binding portion 30 are connected to the shoelaces L which are crossly bond on the instep of the shoes 1. The third binding portion 10, the first binding portion 10 and the second binding portion 20 are respectively provided on the lower portion, the middle or upper portion and the portion where the end of the shoelaces L passes.
Firstly, the adjustment of binding fore for the instep of the shoelaces L using the binding portion 10 will be explained as follows. To create the binding fore, the separated receiving member 11 and the binding member 13 is disposed to be fitted from each other. That is, after the clutch plate 13a of the binding member 13 is disposed to be inserted in the slot 11b of the receiving member 11, the receiving member 11 is fitted in the binding member 13. At this time, the clutch plate 13a of the binding member 13 enters in the slot 11b of the receiving member 1, and then the pressing plate 12a of the adjusting member 12 installed in the installing recess 11c of the receiving member 11 is returned by the elastic member. And, finally, the stopper 12d formed on the other side of the pressing plate 12a is clutched in the clutch recess 13b of the clutch plate 13a. And therefore, the binding force between the receiving member 11 and the binding member 13 is created.
Under this condition, to release the union between the receiving member 11 and the binding member 13, the pressing plate 12a installed in the installing recess 11c of the receiving member 11 is pressed. Then, one side of the pressing plate 12a is pressed and the other side thereof is upwardly rotated with respect to the hinge shaft 12b. The stopper 12d protruded from the lower side of the other side is separated from the clutch recess 13b of the binding member 13. Under this condition, the binding member 13 is separated from the receiving member 11 by pulling the binding member 13.
The second binding portion 20 is to maintain and release the binding of the end of the shoelaces L. The front end of the shoelaces L is inserted in the guiding space 23, and it is rotated the guiding bar 24, and then it is entered the space between the guiding bar 24 and the first post 25. Subsequently, it is entered in the space between the first post 25 and the second post 26.
When the end of the shoelaces L is pulled, the guiding bar 24 is moved to its one side. And then, it presses one end of the shoelaces L and the upper end of the shoelaces L also presses the lower end of the shoelaces L, and therefore their binding is maintained.
Finally, the third binding portion 30 has a symmetrical figure in left and right. Each end of the shoelaces L is inserted in the third binding portion 30 at its side and it is downwardly passed, and then it is upwardly pulled out, and therefore the close connection of the shoelaces L is adjusted.
In the third binding portion 30, one end of the shoelaces L is inserted through the exit 33′ formed on both side of the body 31, and the inserted shoelaces L are rotated to the pair of direction change protrusion 32′ formed in the body 31′ with a distance. And, finally, they are drawn out through the exit 33′
The drawn one end of the shoelaces L are connected to the connecting ring C near to the upper portion of the third binding portion 30. Under this condition, when the shoelaces L passed through the third binding portion 30 are pulled, its binding force is enhanced. Also, when the third binding portion 30 is upwardly pulled from the instep of the foot, its binding force is released.
Although the preferred embodiments of the present invention have been described, it is understood that the present invention should not be limited to these preferred embodiments but various changes and modifications can be made by one skilled in the art within the spirit and scope of the present invention aimed.
