Description
- None.
- Not Applicable.
- A. Field of the Invention
- The field of the present invention relates generally to footwear having a safety component to protect part of the wearer's foot. In particular, the present invention relates to such footwear that is configured to protect part of the foot from an impact force. Even more particularly, the present invention relates to such footwear that protects the heel area of the wearer's foot from an impact that could otherwise injure the Achilles tendon and surrounding area of the foot.
- B. Background
- The use of devices in footwear to protect a portion of the wearer's foot from injury is well known in the art. For instance, many shoes, boots and other footwear have a sole on the bottom of the footwear that is configured to protect the bottom of the wearer's foot from impact forces that result from walking or running over rough terrain or from sharp objects, such as sticks, broken glass, pins, rods and the like, that would otherwise puncture the bottom of the shoe and cause injury to the bottom of the foot. Typically, hiking boots and the like also include a shoe body that substantially envelopes the foot which is made out of materials that are selected to protect the wearer's foot from abrasions and the like which would result from contact against rocks, trees or other objects that could injure the sides or top of the foot. Generally, the devices and materials which are utilized in common footwear to protect the bottom and sides of the foot are primarily designed to achieve certain comfort and/or aesthetic objectives and have only a limited ability to protect the wearer's foot against more severe impact forces.
- Many occupations place the worker at risk of injury to his or her foot, including harm that could result from objects that may drop or fall on the worker's foot, objects which could puncture the bottom of the foot and objects which may run over or hit against the foot. To reduce the risk of injury to the worker's foot, most companies require the workers who work in areas where foot injuries are possible to wear safety shoes or boots. The typical safety shoe (which includes boots) comprises a steel or other metal rigid or semi-rigid plate incorporated into the sole or insole of the shoe to provide puncture resistence for the underside of the shoe so as to prevent injury to the bottom of the wearer's foot. Because the plate usually extends over the entire sole or insole portion of the shoe, it can add significantly to the weight of the shoe and reduce the shoe's flexibility, which can result in discomfort for the wearer. The typical safety shoe also includes a safety toe component that is configured to protect the forward, toe area of the wearer's foot. As with the plate, the conventional safety toe is made from steel and is at least semi-rigid, most often quite rigid. The typical safety toe component is configured to substantially envelope the wearer's toes to protect the toes from objects that may fall on top of the shoe or hit against the front and/or sides of the toes. Generally, the weight and stiffness at the toe area of the safety shoe adds to the weight of the shoe and makes the shoe somewhat uncomfortable to wear for long periods of time. To reduce the weight and discomfort of the safety plate and/or toe components, some safety shoe manufacturers have developed safety shoe components that are made out of hardened plastic, composites and/or other relatively lightweight but strong materials.
- In addition to the typical foot related injuries that can result from an object puncturing the bottom of the shoe or an object falling on or running over the toe area of the shoe, many people are exposed to potential injury to the heel area of their foot. A person's heel area can be injured as a result of a cart, Gurney, bicycle or other apparatus, typically wheeled or on a wheeled object (such as a hand cart or forklift) running into the rear of their foot. As many people are aware, an impact against the rear of the foot can be very painful and result in difficulty in running, walking or even laying or sitting down with any pressure on the heel. Naturally, this can result in the inability for a person to comfortably work and/or perform other day-to-day activities. The rear portion of a human foot comprises the heel bone (the calcaneus), which sits below the ankle bone (talus) and behind the bones at the middle of the foot (the cuneiforms and cuboid), and the Achilles tendon (also known as the calcaneal tendon or tendo calcaneus), which extends behind the back of the ankle to connect the calf (gastrocnemius) and soleus muscles to the heel bone. Depending on the severity of an impact against the rear of a person's foot, the Achilles tendon and/or the heel bone can be damaged. In severe impact events against the rear of the foot, the Achilles tendon can be severed and/or the heel bone can be fractured, both of which cause significant pain, typically need surgery to repair and require extensive time for recovery. Work related injuries of this type typically result in significant loss of employee availability and cost to the employer.
- Although potential foot injuries from an object puncturing the bottom of the shoe or an object falling on or running over the toe portion of the foot have been generally well addressed in the prior art, injuries to the rear of the foot from impact events have not been addressed or have not been adequately addressed. As a result, there continues to be work and non-work related injuries to the rear of the foot that cause people significant pain, sometimes nearly debilitating pain, and which result in loss of income and require medical expenses. What is needed, therefore, is an improved shoe that includes a device to protect against impact injuries to the rear portion of a person's foot. The preferred shoe should prevent injury to the wearer's heel bone and/or Achilles tendon from an impact directed against the back of the shoe. Preferably, the shoe having a device to protect against injuries to the rear of the foot can be configured as a standard shoe, safety shoe or boot. The shoe should be comfortable to wear and relatively inexpensive to manufacture.
- The shoe having rear impact guard of the present invention solves the problems and provides the benefits identified above. That is to say, the present invention discloses a shoe, which may be configured as a standard or work shoe or a boot, having a guard device at the rear of the shoe to protect the rear of the wearer's foot from injury as a result of an impact against the rear of the shoe. As such, the shoe of the present invention protects against impact events that can harm the heel bone, Achilles tendon or other areas of the back of the wearer's foot. In a preferred embodiment, the impact guard device is at the back of the shoe and extends from at or near the bottom of the shoe (above the sole) to at or near the top of the shoe to protect the entire heel area of the wearer's foot. The impact guard device can be made out of metal, hard plastic, various composites or other materials that are or can be made sufficiently rigid so as to prevent an impact against the back of the shoe from injuring the wearer's heel area. In one embodiment, the impact guard device is incorporated into the body of the shoe. In another embodiment, the impact guard device is disposed on the exterior of the shoe. In either embodiment, the shoe can be manufactured in a manner that does not make the shoe uncomfortable to wear and/or expensive to manufacture.
- In a primary embodiment of the present invention, the shoe having rear impact guard generally comprises a generally rigid guard device at or near the second or back end of the shoe to prevent any impact force from injuring the back of the wearer's foot. The guard device has a body member with first end and a second end. In a preferred embodiment, the first end of the body member is at or near the top end of the back of the shoe and the second end of the body member is at or near the bottom end of the back of the shoe. The guard device can be made out of metal, hard plastic, composites and a variety of other rigid or at least substantially rigid materials. In the preferred embodiment, the guard device is embedded inside the body of the shoe at or near its second end, which defines the heel section of the shoe. Alternatively, the guard member can be affixed to the outer surface of the shoe body at the second end of the shoe. In one embodiment, the body member of the guard device is an elongated rod having a round, square, rectangular, oval or other cross-section. In another embodiment, the guard device is a rectangular plate. In yet another embodiment, the guard device has a curved shaped that generally conforms to the shape of the heel section of the shoe so it can also protect the sides of the user's heel from injury due to an impact force. In this embodiment, the body member comprises a pair of wing members that extend in the shoe's heel section generally outward from the second end of the shoe toward the first end of the shoe. The shoe of the present invention can also include the prior art plate at or near the sole of the shoe and the prior art safety toe to provide substantial protection for the wearer's foot.
- Accordingly, the primary aspect of the present invention is to provide a shoe with a rear impact guard that has the advantages discussed above and overcomes the disadvantages and limitations associated with presently available shoes and safety shoes.
- It is an important aspect of the present invention to provide a shoe having rear impact guard that is configured to protect the heel area of a wearer's foot from an impact force against the rear of the shoe. More specifically, it is an important aspect of the present invention to provide a shoe having rear impact guard that substantially protects the rear or heel area of the wearer's foot from impact forces which would otherwise injure the heel bone and/or Achilles tendon, resulting in pain, loss of work and medical expenses.
- It is also an important aspect of the present invention to provide a shoe having rear impact guard that is adaptable for use with a variety of different sizes and types of footwear, including shoes, safety shoes and boots.

- A shoe that is configured pursuant to a preferred embodiment of the present invention is identified generally as 10 in
FIGS. 1 , 2, 4, 6 and 7. Theshoe 10 is configured to be worn by a person to protect the rear of the wearer's foot, specifically the area around the heel bone and the Achilles tendon, from an impact force that could otherwise injure the person. As with a standard shoe, theshoe 10 of the present invention has ashoe body 12 with afirst end 14 that defines thetoe section 16 of theshoe 10 and asecond end 18 that defines theheel section 20 thereof. Theshoe 10 of the present invention has a sole 22 at the bottom of the shoe that supports the wearer's foot as he or she walks across the ground or other surfaces. As set forth above, conventional safety shoes can include a plate, typically made out of metal and at least semi-rigid, that protects the bottom of the wearer's foot from objects that puncture the sole 22 and a toe guard, also typically made out of a rigid metal, that protects the wearer's foot from objects that fall on or run overtoe section 16. AlthoughFIGS. 1 , 2 and 4 illustrate a typical shoe andFIGS. 6 and 7 illustrate a typical boot, which for the present disclosure are both referred to as a “shoe,” persons skilled in the art will readily recognize that the present invention is not limited to these types of shoes and that the principles of the present invention can be incorporated into a wide variety of different configurations and types of shoes. Although not shown in the figures, those skilled in the art will also readily understand that theshoe 10 of the present invention can include the prior art plates at or near the sole 22 of theshoe 10 and the prior art toe guards at thetoe section 16 of theshoe 10. - To achieve the desired protection against injury to the foot resulting from an impact force against the back of
shoe 10, theshoe 10 of the present invention comprises aguard device 24 beneficially positioned inheel section 20 ofshoe 10. Various sizes and configurations forguard device 24 can be utilized with theshoe 10 of the present invention. In each such embodiment, however, theguard device 24 should be sized and configured to protect the wearer's heel, including the heel bone and Achilles tendon, from an impact against thesecond end 18 ofshoe 10. In the embodiment ofFIGS. 1 through 3 , theguard device 24 has abody member 26 that is an elongated rod having afirst end 28 and asecond end 30. In a preferred configuration of this embodiment, the rod-shapedbody member 26 is sized such that itsfirst end 28 is substantially at or near thetop end 32 of thesecond end 18 ofshoe 10 and itssecond end 30 is substantially at or near thebottom end 34 of thesecond end 18 ofshoe 10, which is at or near where the top of the sole 22, as best shown inFIG. 2 . Thebody member 26 is a rigid or substantially rigid member that can be manufactured out of metal, hard plastic, various composites or other materials that will provide a rigid barrier against any impact force that hits thesecond end 18 ofshoe 10. As best shown inFIG. 1 , thebody member 26 should be shaped to substantially conform to the shape of thesecond end 18 ofshoe 10 so that it does not interfere with the use ofshoe 10. In this embodiment, theguard device 24 is disposed insideshoe body 12 at theheel section 20. Preferably, theshoe 10 is manufactured such that the user thereof will not feel or otherwise notice the placement of theguard device 24 inside theheel section 20 ofshoe 10.FIG. 3 showsguard device 24 separate fromshoe 10. As will be understood by those skilled in the art, the rod-like body member 26 ofguard device 24 can have a cross-sectional shape that is round, square, rectangle, oval or a variety of other shapes. In one embodiment, thebody member 26 has a round cross-section approximately 0.15 to 0.30 inches in diameter. If desired, thefirst end 28 can be below thetop end 32 of thesecond end 18 ofshoe 10 and thesecond end 30 can be above thebottom end 34 of thesecond end 18 ofshoe 10. - In the embodiment of
FIGS. 4 and 5 , theguard device 24 is a generally rectangular plate and disposed on theouter surface 36 ofshoe body 12. Preferably, this embodiment is utilized when thesecond end 18 ofshoe 10 is sufficiently wide that thebody member 26 ofguard device 24 will not extend beyond the outer edges of theshoe body 12. If desired, the rectangular shapedguard device 24 can be disposed inside shoe body 10 (as with the rod shaped embodiment) and, likewise, the rod shapedguard device 24 can be disposed on theouter surface 36 ofshoe body 12. In an alternative embodiment, theguard device 24 can be disposed insideshoe 10, although this is likely not a preferred embodiment as theguard device 24 could possibly rub against the user's foot and makeshoe 10 uncomfortable to wear. In the embodiment ofFIGS. 4 and 5 , theguard device 24 can be affixed to theouter surface 36 utilizing an adhesive or various attachment devices suitable for the materials ofshoe 10 andguard device 24. In one configuration of this embodiment, the rectangular shapedguard device 24 has abody member 26 that is approximately 0.75 to 1.20 inches wide and 0.15 to 0.35 inches thick. Preferably, the height ofbody member 26 is selected so as to substantially extend between thetop end 32 andbottom end 34 of thesecond end 18 ofshoe 10, as shown inFIG. 4 . - In the embodiments of
FIGS. 6 through 9 , thebody member 26 ofguard device 24 is shaped to at least generally conform to the shape ofshoe body 12 at theheel section 20 ofshoe 10. In this embodiment, thebody member 26 comprises a pair of wing members, such asfirst wing member 38 andsecond wing member 40 shown onFIG. 8 , that extend outwardly relative to the main portion ofbody member 26 to at least partially wrap around the sides ofheel section 20 at thesecond end 18 ofshoe 10. As best shown in the side view ofFIG. 6 (with the opposite side being a mirror image thereof) and the top view ofFIG. 9 , thebody member 26 is curved such that thewing sections 38/40 extend from thesecond end 18 towards thefirst end 14 ofshoe 10, though still remaining within theheel section 20 ofshoe 10. Preferably, the curvature ofbody member 26 is substantially in conformity with the shape of theshoe body 12 at thesecond end 18 ofshoe 10. Generally, this will result inbody member 26 being narrower near thefirst end 28 and wider near thesecond end 30, as best shown inFIGS. 7 and 8 . The benefit of thewing members 38/40 of this embodiment is to provide some protection to the sides of the wearer's foot at theheel section 20 ofshoe 10 from an impact force at this location. In the configuration of this embodiment shown inFIGS. 6 and 7 , theguard device 24 is embedded inside the shoe body 12 (as with the embodiment ofFIG. 1 ). Alternatively, theguard device 24 of this embodiment can be affixed to theouter surface 36 ofshoe body 12, as shown with regard to the embodiment ofFIG. 4 . As with the other embodiments, thebody member 26 should be made out of a rigid material, such as metal, hard plastic and certain composites. Preferably, the material chosen for thebody member 26 is relatively lightweight and inexpensive to produce so as to maintain the comfort and control the cost ofshoe 10. As with the previous embodiments, it is preferred that thebody member 26 substantially extend from at or near thetop end 32 ofshoe body 12 at thesecond end 18 ofshoe 10 to at or near itsbottom end 34, as best shown inFIGS. 6 and 7 . - As stated above, in the preferred embodiment, the
guard device 24 is embedded insideshoe body 12 at theheel section 20 ofshoe 10, preferably at thetime shoe 10 is manufactured. Alternatively, theguard device 24 can be affixed to theouter surface 36 ofshoe body 12, which can be installed after the manufacture ofshoe 10. In the latter embodiment, theguard device 24 can be sold as an after-market product that is installed by the user on an existing shoe, including ashoe 10 that is configured as a safety shoe with a plate at or near the sole 22 ofshoe 10 and/or a safety toe device at thetoe section 16 ofshoe 10. An improved safety shoe would incorporate theguard device 10 of the present invention to provide ashoe 10 with protection against punctures through the bottom of theshoe 10, injury to toes from an object falling on or running over thetoe section 16 ofshoe 10 and injury to the heel area from an impact force against thesecond end 18 ofshoe 10. In use, the user would wearshoe 10 in the same manner as he or she would wear any other shoe, just with the added benefit ofguard device 24 protecting against impact forces against thesecond end 18 ofshoe 10, thereby reducing the likelihood of injury to the heel bone or Achilles tendon of the user's foot. - While there are shown and described herein specific forms of the invention, it will be readily apparent to those skilled in the art that the invention is not so limited, but is susceptible to various modifications and rearrangements in design and materials without departing from the spirit and scope of the invention. In particular, it should be noted that the present invention is subject to various modification with regard to any dimensional relationships set forth herein and modifications in assembly, materials, size, shape and use. For instance, there are numerous components described herein that can be replaced with equivalent functioning components to accomplish the objectives of the present invention.
