Description

The present invention relates to shoes and, more specifically, to a shoe sole having a structure for minimizing the possibility of injury during torsional or pivoting movements that may occur during certain sports, and / or for improving consumer qualities, thereby so that the rotational movement of the foot occurs with the movement of the body.

A shoe sole comprising a pivot plate for minimizing the possibility of injury of the type discussed is described in International Patent Applications PCT / AU91 / 00590, PCT / AU94 / 00002 and PCT / AU96 / 00634 (“earlier applications”) for the present invention. In earlier applications, the pivot plate is generally circular in shape embedded in a recess in the sole and is capable of pivoting by a limited angular value defined by the series of interlocking protrusions and depressions between the pivot plate and the sole structure. In practice, the actual action of the pivot plate is to allow the sole to pivot about the pivot plate if the foot pivots or rotates when the pivot plate contacts the ground. The pivot plate undergoes elastic displacement, which results in the pivot plate being returned to its original position relative to the sole when the sole is lifted relative to the ground.

Although the various swivel plate devices described in earlier applications are effective, it is nevertheless difficult to adapt the swivel plate design to the mass production technology commonly used in shoe manufacturing, especially sports shoes with molded soles. This difficulty significantly impedes the industrial application of this technology.

According to one aspect of the invention, there is provided a module with a pivot plate for incorporation into a shoe sole in the form of a pre-assembled unit, comprising a base part, a pivot plate that is mounted on the base part for limited rotation relative to the base part in each direction from the initial position, with an elastic element mounted between the pivot plate and the base part to ensure that the pivot plate returns to its original position after pivoting, and an o-ring attached e to the base part to be located outside the periphery of the rotary plate so that the rotary plate is placed between the sealing ring and the base part, while the outer surface of the rotary plate is in sliding contact with the adjacent surface of the sealing ring, whereby the sealing ring prevents dirt or slush from entering the module moreover, the module is configured to be mounted in a preformed sole structure so that the pivot plate is open through the hole in the outer sole of this structure.

The use of a module with a rotary plate means that modules manufactured and assembled on the same production equipment can be delivered to a shoe manufacturer who does not have the special technologies necessary for the production and assembly of a module with a rotary plate. In this case, the shoe manufacturer by molding makes the outer sole in the usual way, but with a recess of a round or other appropriate shape passing through the sole to receive the pivot plate. Then put the module on the sole so that it is between the upper surface of the molded outer sole and the lower surface of the inner sole, and attach it.

In practice, the base plate, the rotary plate, and the o-ring are molded from hard plastic, such as polyurethane (for example, thermoplastic polyurethane) or nylon, or from a light metal or alloy, or from a combination of such materials.

Preferably, the pivot plate of the preassembled assembly comprises a tread disc protruding through an opening in the outer sole for contacting the ground.

The adjoining surfaces of the rotary plate and the o-ring in the sliding contact preferably comprise at least one annular rib extending from one of the surfaces into an annular groove of the corresponding section in the other of these surfaces.

The base part preferably has a generally round shape and comprises tabs protruding radially outward to facilitate attachment of the device to the sole structure.

Also, the base part preferably extends outward relative to the o-ring to facilitate attachment of the device to the sole structure and / or to provide reinforcement for the sole structure.

Further, according to the invention, there is provided a method for manufacturing a shoe product comprising using an inner sole part, installing a module according to any one of the preceding paragraphs on a downwardly facing surface of the inner sole part, using an outer sole part with a hole having a dimension and arranged to be flush with the pivot plate module, and applying the outer sole of the sole to the lower side of the inner sole of the sole so that the ground-engaging portion of the protrusion plate la through the hole.

As the inner part of the sole to which the module is attached, preferably an inner sole or middle sole is used.

Preferably, the inner part of the sole to which the module is attached has a molded structure and comprises a recess on its lower surface that has a shape complementary to that of the base part so that the base part is placed in the recess.

The module is preferably attached to the inside of the sole by gluing the base to the inside of the sole and / or by rigidly attaching the base to the inside of the sole by means of fasteners passing through parts of the base from the outside of the o-ring.

The invention also provides a shoe made in accordance with the above method.

Also, according to the invention, there is provided a module with a rotary plate for incorporation into a shoe sole in the form of a pre-assembled assembly, comprising a base part, a rotary plate rotatably mounted on the base, and an o-ring applied to the base part to be outside the periphery of the rotary plate so that a rotary plate is placed between the sealing ring and the base part with the opposite surfaces of the rotary table and the sealing ring in the sliding contact for i to prevent dirt or slush from entering the module, with the base part extending outward beyond the outer periphery of the o-ring to allow the upper surface of the base part to be attached to the lower surface of the sole structure lying above the outer sole by adhesive bonding to it and / or by rigid bonding fasteners passing through parts of the base part outside the o-ring.

The base part preferably extends outward from the o-ring through a plurality of radially extending tabs, and the pivot plate comprises a tread disc engaging with the ground.

In addition, the pivot plate is preferably a pivot disk mounted on the base part by means of a rivet passing through the pivot plate and the base part, and the tread disk is superimposed on the pivot disk, protruding from it and closing the rivet.

The rotary plate can be made in the form of a disk, including a structure formed in one piece that engages with the ground and continues along the axis downward from the disk, while the rotary disk is rotatably mounted on the base part by means of a rivet passing through the rotary disk and the base part.

Further, according to the invention, there is provided a module with a rotary plate for embedding in a shoe sole in the form of a pre-assembled assembly, comprising a base part and a rotary plate mounted on the base part and sealed relative to the base part to prevent dirt or slush from entering the module, the module being made with the ability to install in a preformed sole structure so that the pivot plate is open through an opening in the outer sole of this structure.

The invention also provides a shoe product having an outer sole, and a rotary plate module made in accordance with the first aspect of the invention, mounted as a pre-assembled assembly on the underside of the inner sole, and the portion of the rotary plate engaging with the ground protrudes through the hole, formed in the outer sole.

As the inner sole portion to which the module is attached, an inner sole or middle sole is preferably used.

The inner sole portion to which the module is attached preferably has a molded structure and comprises a recess on its lower side that has a shape complementary to that of the base part so that the base part is placed in the recess.

The complementary forms of the recess and the base part are preferably designed such that the base part is rigidly fixed in the recess against rotation.

The module can be attached to the inner sole by gluing the base part to the inner sole and / or by rigidly attaching the base part to the inner sole by means of fasteners passing through the parts of the base part outside the O-ring.

The base part preferably extends outward from the o-ring to provide reinforcement for the adjacent portion of the sole structure.

Now, only as an example, a preferred embodiment of the invention will be further described with reference to the accompanying drawings, in which:

figure 1 is a view with a spatial separation of the details of the module with a rotary plate according to the invention;

figure 2 is a view with a spatial separation of the parts, similar to the view in figure 1, but shown from below;

figure 3 is a bottom view of the assembled module;

figure 4 is a partial section on an enlarged scale, showing the sealing interaction between the sealing disk and the rotary plate;

5 is a view similar to that of FIG. 4 and showing a modified sealing device;

6 is a longitudinal section of the sole of the shoe having a module installed therein with a rotary plate, shown in figures 1-4, and

7 is a bottom view of a module with a rotary plate, in which the rotary plate is made in one piece with the ribs meshing with the ground.

As shown in figures 1 and 2, the module with a rotary plate has a base plate 2, a rotary plate 4 and a sealing ring 6. The interacting surfaces of the base plate 2 and the rotary plate 4 are formed with interacting protrusions and depressions, which are generally indicated, respectively , positions 8, 10 and by means of which the rotary plate 4 is precisely located relative to the base plate 2 for rotation by a limited angular value around the Central axis. Between the base plate 2 and the pivot plate 4, a spring 12 is arranged to apply rotational displacement to the pivot plate 4 in order to return it to its original position after rotation in any direction of rotation. Although the spring 12, as shown, is a coil spring, other types of springs are also suitable. The interaction between the protrusions and depressions 8, 10 occurs in such a way that the rotary plate 4 is able to rotate approximately 30 ° in each direction of rotation from the initial position.

The rotary plate 4 is held assembled with the base plate 2 by means of a rivet 14 located on the axis of rotation. After the assembly of the rotary plate 4 with the base plate 2, a sealing ring 6 is applied to the base plate 2 along the periphery of the rotary plate 4 and attached to the base plate 2 by glue, ultrasonic welding or snap-fit clamp. The sealing ring 6 has a cross section with a ledge (see figure 4) and closes the outer periphery of the rotary plate 4, forming a sliding seal with it to prevent access of dirt or slush between the rotary plate 4 and the base plate 1, which otherwise could interfere proper operation of the turntable. To further improve the sealing effect, in the modification shown in FIG. 5, one or more V-ribs 15 are made around the periphery of the rotary plate 4, which engage with grooves with a corresponding cross section in the adjacent surface of the sealing ring 6 (or, with on the other hand, ribs could be formed on the o-ring and grooves on the pivot plate). This improved sealing effect is especially useful for shoes that can also be worn on the beach, or for shoes that are specifically designed for use in contaminated areas, such as soccer shoes. Although it is preferable to use an o-ring (with or without ribs / grooves), the seal, however, could be achieved in an alternative way.

A molded tread disc 16 is applied to the outer surface of the rotary plate 4, for example by gluing, which covers the rivet head 14.

The base plate 2 of the module contains radially protruding tabs 2a, which facilitate the installation of the module on the sole of the shoe, providing fixation between the base plate and the sole, which will withstand the torsional forces applied to the base plate. In the sole structure, the module is mounted inside the outer sole, while the tread plate 16 of the pivot plate protrudes through a circular recess in the outer sole, extending slightly beyond the lower surface of the outer sole. The module can be glued to the inner sole structure with adhesive located between the upper surface of the base plate and the adjacent surface of the sole structure, and / or attached with rivets or screws through tabs 2a. The method of attachment will depend on the particular design used for the inner structure of the sole. The inner structure of the sole in its simple and inexpensive form may simply consist of an inner sole of cardboard or similar material. In this case, the module can be applied directly to the lower side of the inner sole and fixed in place with adhesive, as well as screws passing through the inner sole and into the tabs 2a. In the inner structure of the sole having a relatively thick molded middle sole or molded inner sole, the molded part is formed with a recess on its lower side, which corresponds to the outer periphery of the base plate and into which the module is inserted and fixed in it against rotation as a result of mating between the two parts; in this case, the adhesive between the base plate and the base of the recess may be sufficient to hold the module in the recess without the need for fasteners extending into the tabs 2a. Fig. 6 shows, by way of example, a module that is inserted into a recess of an appropriate shape formed on the underside of a midsole 18 molded from a suitable material, such as, for example, a copolymer of ethylene and vinyl acetate.

When the module is superimposed on the inner sole structure (specifically, on the inner sole or midsole, depending on the actual design), a preformed outer sole 20 with an opening for receiving the tread disc is applied to the inner sole structure and attached in the usual manner. If the tabs 2a are directly adjacent to the upper surface of the outer sole, as may be the case in a design in which the module is mounted directly on the lower side of a relatively thin insole, then the lower surface of the tabs can also be glued to the upper surface of the outer sole to further improve fastening against twisting effort.

Although the base plate 2 shown has a circular shape enlarged by the radial tabs 2a, any suitable shape can be given to the base plate outside the o-ring 6 to not only facilitate fastening to the inner structure of the sole in the same manner as fastening with the tabs 2a, but also for creating reinforcement for adjacent parts of the sole structure, and this can be especially useful when the module is applied directly to a relatively thin inner sole.

The base plate, the rotary plate and the o-ring are molded or otherwise formed from a relatively hard material (or a combination of materials), such as, for example, from the previously mentioned materials. The tread disc will be molded from a material equivalent to that of the outer sole, which in the case of shoes designed for sports, such as basketball or netball, will be made of a relatively elastic material. However, it should be noted that the rotary plate could be formed in one piece with the corresponding tread disc or other entities engaging with the ground, such as, for example, ribs, hairpins or spikes. 7 shows a module with a rotary plate 4, having made in one piece ribs 22.

As shown in FIG. 6, a module with a pivot plate is mounted in the sole so that the pivot plate 4 with the tread disc 16 is predominantly under the elevation of the foot arch. However, it should be noted that the device could be installed in other parts of the sole, for example, in the heel part. It is possible to install individual modules in the lifting part and in the heel part of the same boot.

The swivel plate module described herein can be manufactured and assembled in one source and then shipped to a number of shoe manufacturers for incorporation into the shoes they make. Although the tread disc 16 applied to the pivot plate can be assumed to form an integral part of the pivot plate, the module can be delivered to the manufacturer without the tread disc, when in practice the tread pattern on the disc will correspond to the tread pattern on the outer sole, and the disc will be formed from same material. In this case, the tread disc can be conveniently provided by the shoe manufacturer in the form of a simple molded part that is applied to the pivot plate before the module is embedded in the sole structure.

Although the rotary plate module described herein is a preferred embodiment of the invention, nevertheless, some of the features of the module have wider applicability. For example, in a modified embodiment, the pivot plate can be mounted for free rotation on the base plate without any restriction on the angular value of the pivot and without bias by the spring acting to return the pivot plate to its original position. This embodiment may be suitable for a limited number of applications, although it should be understood that the described embodiment is preferred in which the pivot plate is capable of pivoting a limited angle in any direction from the initial position and returns to this initial position due to displacement by the spring.

Throughout the text of the description of the invention and the following claims, unless the context requires otherwise, the word “contain” and its changes, such as “contains” and “containing”, means, as it should be understood, the inclusion of the indicated integer or step or a group of integers or steps, and not the exclusion of any other integer or step or a group of integers or steps.

In this description of the invention, a reference to any previous publication (or information derived from it) or to any object that is known is not and should not be accepted as confirmation or recognition, or any form of assumption that the previous publication (or information received from it) or a known object forms part of the generally accepted knowledge in the field of activity to which this description of the invention relates.

Embodiments of the invention are described by way of example only, and modifications are possible within the scope of the invention.
