Full Description:
TECHNICAL FIELD  
         [0001]    The invention generally relates to footwear and more particularly relates to shoes having a foot-massaging effect.  
         BACKGROUND OF THE INVENTION  
         [0002]    Generally, shoes feature an inner sole with a smooth structure. Underneath, the inner sole is provided with a pad of minimal height at least in certain sections, e.g., in the area of the heel and/or the ball of the foot, in order to provide a “softer” step for the person wearing the shoe.  
           [0003]    Furthermore, footwear is known that is designated as bathing shoes or slip-on shoes. Generally, these can be distinguished by a strap or crosspiece that runs over the top of the foot and which attaches the shoe to the person&#39;s foot. Such footwear often consists of extruded or foamed plastic and is often formed in one piece. Furthermore, there is footwear in the form of several pieces with a sole, e.g., consisting of leather or wood, and with a bump-like structure being formed on this sole. Due to the bump-like structure, when the person wearing the shoe walks, his or her sole is massaged by the bumps, which generates good, beneficial blood circulation in the feet of the person wearing the shoes.  
           [0004]    Shoes with smooth inner soles are disadvantageous in that they exert absolutely no massaging effect on the feet of the person wearing the shoes. For shoes with bump-like, foot-massaging structures, the problem always arises that the intermediate spaces between the bumps can become filled with dirt particles. In addition, perspiration secreted by the foot can settle into these intermediate spaces. The substance formed by the dirt and perspiration between the bumps eventually leads to an unpleasant odor and possibly to foot diseases due to fungal bacteria, etc.  
           [0005]    The problem of the invention is to create a shoe of the type mentioned in the introduction, which can produce a relatively strong foot-massaging effect and which simultaneously provides essentially odor- and dirt-free use of the shoe.  
           [0006]    The problem is solved according to the invention by means of a pad, which is arranged in the interior of the shoe above the sole, which contains a massaging element and/or medicinal agents, and which consists of a flexible base plate adapted to the shape of the sole on the bottom side and on the top side an elastic protective nonwoven fabric rigidly connected to the base plate.  
           [0007]    It is known that the sole of a person is divided into different reflex zones. Medically, there exists a direct connection between the individual foot reflex zones and the organs or body parts of the person. Targeted massaging at certain foot reflex zones has a direct effect on the health of the corresponding body part or organ. The pad containing the massaging element and/or medicinal agents provides continuous massaging of the sole of the person wearing the shoe while the shoe is on the foot. The continuous massaging of the sole of the person positively stimulates the well-being of the person. This can be realized especially well by the effect of the sole massage promoting blood circulation. The elastic nonwoven fabric, which is arranged on the top side of the massaging element and/or the medicinal agents and which is rigidly connected to the flexible base plate, prevents the penetration of foot perspiration and dirt into the pad, which provides for odor-free use of the shoe.  
           [0008]    Preferably, a cap that releases medicinal agents is arranged at the shoe tip in the interior of the shoe. In this way, the medicinal agents can act on the toes of the person wearing the shoe. The medicinal agent can exert an effect, e.g., a perspiration-blocking function and/or a heating function. The cap containing the medicinal agents can be inserted into the interior of the shoe by the manufacturer during production or at a later time.  
           [0009]    According to a first configuration of the shoe according to the invention, the massaging element is formed as a plurality of bumps, which are arranged on the base plate in uniform or offset rows. Just a plurality of regular or irregular bumps provides an especially effective massaging of the soles, because the heads of the bumps easily press into the soles at point contacts and the massaging effect is generated by the rolling of the foot during walking. Furthermore, the bumps are formed in one piece with the base plate. In this way, the base plate and the bumps are produced in a simple way, e.g., through injection molding. Advantageously, the bumps have the shape of hemispheres with their rounded part pointing into the interior of the shoe.  
           [0010]    According to a second configuration of the invention, the massaging element is formed as a plurality of balls, which are arranged loosely and irregularly or in uniform or offset rows on the base plate. In principle, the balls have the same effect as the previously mentioned bumps; however, the balls can move in the pad of the shoe, which causes additional rolling of the balls as the foot rolls while the person wearing the shoe is walking, which has an additional stimulating effect on the sole. Depending on the arrangement of the balls in the pad, namely, loosely or irregularly or in uniform or offset rows, a different massaging effect of the sole can be achieved.  
           [0011]    Preferably, the balls are embedded in an elastic material and/or connected together by an elastic material. The balls can be maintained for a long time without loss of the massaging effect on the sole both due to the embedding in the elastic material and also the connection to the elastic material, which is realized, e.g., by means of elastic crosspieces that connect to the ends of the balls. Here, the balls can be arranged in one plane with the shape of grapes.  
           [0012]    Advantageously, the material of the balls and the elastic material exhibit the same or different Shore hardness values. The massaging effect of the soles can be influenced by the corresponding material pairing. Obviously, the elastic material can be totally different from the material used to produce the balls. Thus, the invention can deal with different materials.  
           [0013]    In order to effectively counteract abrasion of the balls, preferably the balls are provided with a sliding coating on their surface. The sliding coating can be deposited, e.g., after production of the balls or set in the material during production of the balls. Obviously, the use of a sliding-promoting material for the production of the balls is also suitable.  
           [0014]    For a refinement of the pad containing the balls, the heel contains a valve device, which is connected to the interior of the pad filled with the balls. Preferably, the valve device is formed as a one-way valve with ventilation openings formed in the upper material of the shoe. Because the balls in the interior of the pad constantly move and change their position while the person wearing the shoe is walking, a constant low pressure is created in the pad, which continuously changes its position within the pad while the person is walking. This can be perceived as pleasant or also as unpleasant by the person wearing the shoe. The valve now provides the possibility of suctioning surrounding air due to the low pressure in the pad while the person is walking as a compressed medium and guiding the air into the interior of the pad, so that a “softer” step is perceived by the person wearing the shoe. For each step, a high pressure is generated in the pad in turn at each pressure point, which is equalized by guiding air through the ventilation openings in the upper material of the shoe. While the person is walking, surrounding air is thus constantly suctioned, led into the interior of the pad, and then guided through the ventilation openings of the shoe. This realizes a doubled massaging effect, on the one hand, by the balls, and, on the other hand, by the unloaded positions of the pad filled with compressed air. The arrangement of a large air cushion and thus the effect of a “softer” step can also be supported by forming a flexible, expandable chamber in the heel between the ventilation device and the pad filled with balls. The flexible chamber features an increased volume for storing surrounding air, which creates an increase of the air volume in the pad containing the balls.  
           [0015]    In order to prevent damage to the chamber formed in the heel of the shoe due to material wear and tear and use of the shoe, the flexible, expandable chamber is separated on the bottom side by a solid protective plate from the lower region of the heel or the sole. In this way, the heel arranged underneath the protective plate can be replaced when necessary.  
           [0016]    If the pad arranged in the interior of the shoe is filled with medicinal agents, then the pad can be filled with medicinal agents by means of a valve device arranged in the heel. Here, this valve arrangement is likewise built as a one-way valve. Therefore, when necessary, a medicinal agent can be refilled, e.g., by means of a nozzle, when the agent has been partially or completely consumed over the course of time. In addition, an alternative medicinal agent can also be filled into the pad in order to achieve a different medical effect.  
           [0017]    So that the medicinal agent located in the pad can be guided into the shoe interior and thus onto the sole of the person wearing the shoe, the protective nonwoven fabric has a plurality of small pores.  
           [0018]    According to an alternative configuration of the shoe according to the invention, the pad is formed as an insert for loose insertion into the shoe. In this way, any shoe can be provided with a pad customized for the person wearing the shoe by inserting a corresponding insert into the shoe. If desired, the insert can also be removed or replaced by a different insert at any time.  
           [0019]    Furthermore, the cap containing the medicinal agents can be inserted into the tip of the shoe separately or as a component of the pad formed as an insert. In this way, an insertion or exchange of the cap containing the medicinal agents is possible, likewise at any time, into and out of the shoe. Obviously, the cap is likewise provided with a plurality of small pores. Advantageously, the insert is formed with or without a footbed.  
           [0020]    For another advantageous configuration of a pad provided with balls, a flexible spring band surrounds the pad on the inner edge of the pad. The flexible spring band enables a complete filling of the pad with balls, which are pressed into the flexible spring band at the edges due to loading while the person wearing the shoe is walking. Therefore, despite the total filling of the pad, the balls have a certain freedom of motion to generate the massaging effect.  
           [0021]    Furthermore, as previously explained in general with reference to the shoe, the insert can also have a valve device, which is located in the region of the heel, which is formed as a one-way valve, and which is connected to the interior of the insert or the chamber, so that the insert can be provided with a compressed medium and also with a medicinal agent.  
           [0022]    The bumps of the pad or the insert are further formed so that they are hollow and connected to the flexible chamber. Here, the head of each bump is formed as a pressure cap. Through this configuration of the bumps, a better massaging effect is achieved with the bump heads, which press into the sole of the person wearing the shoe under loading and return to their original position again after the loading.  
           [0023]    In addition, the bumps can be assembled into several bump bands. This arrangement can produce very fine massaging effects on the soles of the person wearing the shoes. Preferably, the base plate of the pad has recesses in which the bump bands are placed so that the bands can move.  
           [0024]    For another configuration of the shoe according to the invention, a motor is inserted in the heel of the sole. This motor has a driver arranged eccentric to the motor axis. The driver is connected flexibly to the bump bands. The motor can be turned on and off by means of a switch. An automatic start-up of the motor is also possible, e.g., due to loading or unloading of the heel of the shoe. The motor provides a massaging effect, in addition to that provided by the shape of the bumps, by moving the bump bands in the interior of the pad of the shoe back and forth. This back-and-forth motion is ensured by the eccentric arrangement of one or more drivers to the motor axis. Preferably, the motor is further operated by means of batteries, which are stored in the heel. Different massaging effects can be achieved by arranging the bump bands in the shoe in the longitudinal or perpendicular direction.  
           [0025]    According to a third configuration of the shoe according to the invention, the massaging element includes a ball thread consisting of a continuous thread with balls loosely arranged in a line. This ball thread is inserted into the pad in the form of a spiral. This measure produces a defined guidance of the balls as the foot of the person wearing the shoe rolls while the person is walking, which has a positive effect on the massaging effect. Depending on the shape of the shoe and thus on the shape of the pad, at least one other thread equipped with loose balls is provided, and the ends of this thread are attached to the base plate or to the ball thread. In this way, practically the entire pad is filled with balls. For an alternative configuration, the massaging element includes rows arranged one next to the other each consisting of balls of a continuous thread loosely arranged in a line, with the ends of each thread attaching to the base plate. For both embodiments, a nonwoven fabric strip is preferably inserted in the edge regions of the pad not filled in by balls. The nonwoven fabric strips ensure a tight bundling of the balls.  
           [0026]    For another configuration of the shoe according to the invention, the massaging element is formed as an elastic tube wound into a spiral shape, whose outer end is connected to an air inlet valve configured as a one-way valve and whose inner end is connected to a throttled air outlet. While the person wearing the shoe is walking, a low pressure is built up after time in the tube, and this low pressure opens the air inlet valve and thus guides air into the tube interior. Due to the throttled air outlet, this air can bleed out of the shoe interior only relatively slowly. In this way the tube produces a massaging effect on the sole. In order to provide free access of air to the air inlet valve, the air inlet valve is advantageously arranged behind an opening in the upright edge of the base plate.  
           [0027]    It is understood that the previously mentioned features and the features still to be explained in the following can be used not only in the specified combination, but also in other combinations without leaving the scope of the present invention.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0050]    [0050]FIG. 1 shows a section through a shoe  1 , which has a sole  2  with a heel  14  and an upper material  3 . The sole  2  and the upper material  3  are connected together in a known way. In the shoe interior  4  above the sole  2 , there is a pad  5 , which includes a flexible base plate  6  that is adapted to the shape of the sole  2  and forms the footbed  7 . A plurality of bumps  8  are attached to the base plate  6  in the direction of the shoe interior  4 . The bumps  8  have the shape of hemispheres with the rounded side pointing in the direction of the shoe interior  4 . Above the bumps  8  there is an elastic protective nonwoven fabric  9 , which contacts the bumps  8  and connects to the base plate  6  or the upper material  3  with a raised section  39  at the side. The bumps  8  consist of elastic material, so that they change their shape under loading and are restored to their original shape after unloading. In this way, the foot rolling in the shoe  1  while the person is walking is constantly massaged by the elastic bumps  8  changing their shape.  
         [0051]    A cap  27  is inserted into the shoe tip  26 . This cap contains a medicinal agent, e.g., against athlete&#39;s foot. The agent can be discharged from the cap through relatively small pores in the cap  27 . The cap  27  is formed such that it is constantly spreading itself out. In this way, it is always in close contact with the protective nonwoven fabric  9  and the shoe tip  26 .  
         [0052]    According to FIG. 2, the bumps  8  are arranged on the base plate  6  in rows  10  one next to or behind another, whereby the foot presses in more between the bumps  8  producing a strong massaging effect. In contrast, the bumps  8  in FIG. 3 are arranged in offset rows  10 . This produces a very fine massaging effect.  
         [0053]    The shoe  1  according to FIG. 4 contains a pad  11 , for which a plurality of balls  12  are arranged loosely on the base plate  6 . Under loading, these balls are slightly displaced relative to each other and thus create a massaging effect. The base plate  6  and the protective nonwoven fabric  9  are connected rigidly and possess a transition  13  to the upper material  3 .  
         [0054]    The pad  11  containing the balls  12  is completely sealed and has a feed  15  formed in the heel  14 . At one end of the feed  15 , there is a valve  17 , which can be accessed from outside in the heel  14  and by means of which this pad  11  can be provided with a compressed medium. In this way, the protective nonwoven fabric  9  can bulge out at unloaded points  16 , as shown in FIG. 5. Because the unloaded point  16  changes as the foot rolls in the shoe  1 , a double massaging effect is produced, on the one hand, by the balls  12 , and, on the other hand, by the unloaded point  16  itself. The upper material  3  of the shoe  1  includes ventilation openings  40 , which are arranged like scales and are cut so that moisture and dirt falling from above cannot enter into the shoe  1 . By means of the rolling foot movement, the air located in this pad  11  is discharged through the ventilation openings  40 . This generates a low pressure in the pad  11 , which is equalized by the valve  17 , which is formed as a one-way valve, by means of air being suctioned through the valve  17  due to the low pressure and then guiding the air through the feed  15  into the pad  11 .  
         [0055]    For the embodiment according to FIG. 5, a chamber  18  is provided in the heel  14  between the valve  17  and the pad  11  containing the balls  12  with only a short feed  15  being provided. In the heel  14 , the chamber  18  is protected at the bottom by a protective plate  19 . The heel sole  20  located underneath the plate can be replaced. The chamber  18  is filled with a compressed medium  21 , which bulges the nonwoven fabric when the protective nonwoven fabric  9  is at least partially unloaded. Loading increases the pressure in the chamber  18 , which therefore expands. This sequence increases the massaging effect. Discharged air is replaced in the same way as explained in reference to FIG. 4. If necessary, however, air can also be refilled into the chamber  18  from time to time manually, e.g., with a suitable air pump.  
         [0056]    The shoe  1  according to FIG. 6 has a pad  23 , which contains medicinal agents and which extends over the entire surface of the top side of the sole  2 , which receives pressure from the foot. By means of the valve  17  present in the heel  14  and the feed  15 , the medical pad  23  is filled with medicinal agents. Small pores  24  are worked into the protective nonwoven fabric  9 , as can be seen from FIG. 7, by means of which the medicinal agent is led into the shoe interior  4 .  
         [0057]    [0057]FIG. 8 shows an insert  25  for the shoe  1 . The insert has a pad  5  with bumps  8  and a cap  27 . Through this configuration, it is possible to buy normal shoes and then to realize both a massaging effect and also a medical effect with the insert  25 .  
         [0058]    For the insert  25  according to FIG. 9, the base plate  6  is connected to the protective nonwoven fabric  9  at a peripheral edge  28 . Balls  12  are inserted all over in the insert  25 . A surrounding spring band  29  is placed pointing from the peripheral edge  28  in the direction of the balls  12 . The valve  17 , by means of which the insert  25  can be provided with both a compressed medium, such as air, and also with a medicinal agent, is located in the region of the heel  14  of the shoe  1 . For an alternative configuration that is not shown, the valve  17  can be eliminated, which allows the insert to be used for a normal shoe  1 .  
         [0059]    [0059]FIG. 10 shows a portion of the insert  25  under loading. The foot rolls on the protective nonwoven fabric  9  of the insert  25 . Here, the main instantaneous load acts in the direction of the arrow through the foot region  31 . In this region, the balls  12  are displaced, which presses the spring band  29  together. After the loading, the spring band  29  relaxes and pushes the balls  12  back into their original position. This produces a massaging effect for the foot both during loading and also during unloading.  
         [0060]    [0060]FIG. 11 shows an insert  25  with elastic bumps  8  with a through chamber  34  provided between the inner side  32  of the base plate  6  and the lower side  33  of the bumps  8 . The bumps  8  are hollow and their hollow region  35  is connected to the through chamber  34 . On the outer side the bump head  36  has a pressure cap  37 , which comes into contact with the foot region  31 . In the region of the loading through the foot, the bumps  8  are pressed in the direction of the base plate  6  and their lower side  33  comes into contact with the inner side  32  of the base plate  6 . For a decrease of the inner pressure, i.e., for a low pressure in the through chamber  34 , the inner pressure can be increased again by means of the valve  17 . As the compressed medium, both a gaseous material or a liquid can be used.  
         [0061]    The pressure caps  37  according to FIG. 12 are designed as elastic disks  38 . For strong loading, the bump heads  36  deform inwards and spring back outwards when unloaded. This increases the massaging effect even more.  
         [0062]    A motor  41  is inserted in the heel  14  in the shoe  1  according to FIGS.  13 - 15 . This motor is operated by appropriate batteries  42 . The motor  41  can be turned on by means of a switch that is not shown. However, automatic starting of the motor  41  by loading of the heel  14  is also possible.  
         [0063]    The pad  5  with bumps  8  is inserted into the shoe interior  4 . The pad is covered on the top side with a flexible protective nonwoven fabric  9 . A driver  43  is provided between this pad  5  and the motor  41 . A driver bolt  45  is held off-center to the motor axis  44  in the driver. The driver  43  is supported perpendicular to the pad  5  and thus has freedom of movement in the longitudinal direction of the shoe  1  because the driver is located to an extent eccentric to the motor axis  44 .  
         [0064]    In the longitudinal direction of the shoe  1 , the bumps  8  are assembled into a bump band  46  with several bump bands  46  being arranged one next to the other. The base plate  6  of the pad  5  has band recesses  47 , in which the bump bands  46  can move. The bumps  8  of the bump bands  46  project with their heads  36  through elongated holes  48 , which are aligned in the longitudinal direction of the shoe  1  and whose length corresponds to the diameter of the bumps  8  plus the freedom of movement. The protective nonwoven fabric  9  contacts the bumps  8  and is pressed around the bumps  8  by the foot. The motor  41  moves all bump bands  46  by means of the driver  43 . The bands are moved back and forth in alternating longitudinal movements and thus produce a massaging effect. It is, of course, also possible to arrange the bump bands  46  perpendicularly in the shoe  1 . Opposite the bump head  36  there is a sliding dome cap  49 , with which the bumps  8 , and thus the bump bands  46 , are supported in a sliding manner on the base plate  6 .  
         [0065]    [0065]FIG. 16 shows an alternative configuration of a bump band  46 . The bump head  36  projects out of a bump hole  50 . There are diagonals  51  towards the bump hole  50  in both directions of the displacement of the bump band  46 . With the motion of the bump band  46 , these diagonals allow the bump head  36  to be pushed in and out of the bump pad  5 . The material of the bump band  46  is elastic and formed such that the material-specific elastic spring effect presses the bump head  36  out of the bump hole  50 .  
         [0066]    For the shoe according to FIGS. 17 and 18, the pad  67  includes balls  52 , which are arranged one next to the other between the base plate  6  and the protective nonwoven fabric  9  and which each have a central through hole  53 , through which a thread  54  is passed. The thread thus holds the balls  52  together and forms a ball thread  55 , which is placed in the pad  67  in the form of a spiral. A surrounding edge  56  of the base plate  6  aligned in the direction of the shoe interior  4  holds the ball thread  55  in position. Another thread  57  equipped with loose balls  52  is provided in a region, which is not filled by the ball thread  55 . This thread  55  [sic;  57 ] is attached at its ends to the ball thread  55 . Thus produces the largest possible arrangement of balls  52  on the base plate  6 . For better clarity, the threads  54  and  57  are shown in FIGS. 17 and 18 by a thick, full line. The regions  58  not filled by balls  52  are filled with elastic nonwoven strips  59 , which forces the balls  52  to always be close together. Under the loading by a foot, the balls  52  get out of the way, i.e., they slide or slip away from the direct pressure point, which produces a massaging effect.  
         [0067]    Another alternative configuration of the shoe  1  is shown in FIGS.  19 - 22 . In the peripheral edge  56  of this pad  68  there is a one-piece, elastic tube  60 . Behind the opening  61  of the peripheral edge  56 , there is the outer edge of the tube  60 , in which an air inlet valve  62  is sealed as a one-way valve. The inner end of the tube  60  is connected to a throttled air outlet  63 . In the air inlet valve  62 , a spring-loaded pressure plate  64  is present with the spring  65  acting on the pressure plate  64  exhibiting only a weak characteristic curve. The spring can be pulled back for the generation of a low pressure in the tube  60  when pressure is exerted on the tube  60  by a foot, which releases the inlet opening  66  of the air inlet valve  62 . The air outlet  63  has an outlet hole  65  that is relatively small in diameter and that acts like a throttle. The air can be discharged from the outlet hole  65  only relatively slowly, whereby under the loading by the foot a counterpressure is always present in the tube  60 . This produces a massaging effect, particularly when the foot rolls in the shoe  1 .
