Description
- Field of the Invention
- The present invention relates to shoes and more particularly pertains to a new removable heel connector apparatus.
- Description of the Prior Art
- The use of shoes with removable heel is known in the prior art. Known prior art shoes include U.S. Pat. Nos. 5,953,836; 8,112,908; 8,505,218; 8,657,110; 8,832,968 and 9,009,990.
- While these devices fulfill their respective, particular objectives and requirements, they are generally weak in strength and not durable in daily use. The aforementioned patents do not disclose a new removable heel connector apparatus providing quick and simple mechanism of locking and releasing the removable heel against withdrawal from the shoe and providing strength and durability in use to a shoe with removable heel as if an ordinary shoe without removable heel.
- In general the present invention is directed to a wholly unique removable heel connector apparatus. The structure of the present removable heel connector apparatus comprises a shoe, a heel connector, a heel, a heel release, a release cover and two springs. The shoe comprises a top shoe sole and a bottom shoe sole having a protrusion, a connector opening, a thrust surface and a connector cavity. The heel connector includes a bolt having a slot and a tilt surface and includes a torque balance having an enforcement portion. The heel includes a button opening, a sole cavity having a bolt cavity, a cover ledge, a thrust wall and two screw holes. The heel release includes a push button and a detent plate having a plate opening, a detent and two spring recesses. The release cover includes a bolt opening and two screw openings having screw recess.
- In relation to the assembly of the removable heel connector apparatus, the connector opening and connector cavity provide a fixed assembly relation between the shoe and the heel connector. The protrusion and the sole cavity provide relative assembly relation between the shoe and the heel. At full insertion of the bolt into the heel, the thrust surface contacts with the release cover and provides stops limiting the insertion of the bolt into the heel.
- The heel connector is the key feature revealing novelty and non-obviousness of this invention.
- The first role of the heel connector in this invention is to connect the removable heel against withdrawal from the shoe. During the insertion of the bolt into the heel, the tilt surface interacts with the detent and depresses the spring in a tilting manner. At full insertion of the bolt into the heel, the detent plate of the heel release is projected outwardly by the bias of the spring thrusting against the heel at thrust wall and against the detent plate at the spring recess urging the detent to interlock the bolt at the slot. This illustrates the mechanism of locking the heel against withdrawal from the shoe. The heel may be withdrawn from the shoe by depressing the push button. It depresses the spring and moves the detent out from the slot to unlock the heel from the shoe.
- The second role of the heel connector in this invention is to balance the stress acting on the heel from the ground and the stress acting by the user's foot on the walking shoe. The heel connector should be integrally cast or machined from relatively strong and durable material, such as metal or steel. As the heel connector starts from the toe area of the shoe and ends inside the heel, it provides strength and durability in use to a shoe with removable heel as if an ordinary shoe without removable heel.
- Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.
