Abstract

A shoe 10 comprises a body 12 and a heel 14. The heel 14 comprises a plurality of sections 16, 18, 20, with at least a first section being fastened to a second section such that the length (height) of the heel can be altered. The sections may be fastened to one another by screw threads or by complementary projections and recesses. The heel sections 16, 18, 20 may be telescopic such that at least a first section can retract within a second section. In another embodiment the heel sections (24, 26, figure 3) may be hinged to one another, or alternatively the whole heel 14 may be hinged to the shoe body 12 (see figure 4). In a further embodiment the heel sections may be detachable from one another. In addition, or as a separate embodiment, the heel 14 may be detachable from the shoe body 12.

Description

ADJUSTABLE SHOE

This invention relates to a shoe having an adjustable heel. The invention is suitable for use with shoes having either a detachable heel or a heel permanently attached to the shoe.

High heeled shoes are commonly worn by women. However, wearing high heels constantly for a long period of time can be uncomfortable and it is common for a woman to want to wear flat shoes after they have worn high heels. For example, after a day at work in high heels flat shoes may be desired for the journey home.

UK Design 3013766 shows a shoe having a stiletto heel which can be attached and detached from the sole of the shoe using a screw-like attachment at one end of the heel.

Whilst this allows a shoe to be easily converted from a flat shoe to a high heeled shoe, and back again, it also means that the heel must be safely stored somewhere and as it is a separate item is liable to be lost. Additionally, the means for receiving the screw in the sole of the shoe will be a hole, which unless covered by secondary means may store dirt and other substances which will need to cleaned out before the high heel can be inserted again.

According to a first aspect of the invention there is provided a shoe including a shoe body and a heel, the heel comprising a plurality of segments, a first segment including a fastening means arranged to engage with a fastening means on a second segment the fastening means arranged such that the length of the heel can be altered.

Preferably the fastening means comprise a thread on a first segment and a complimentary thread on a second segment. The fastening means may, alternatively, comprise a projection on a first segment that is arranged to engage with a complimentary depression in a second segment.

The first segment may be arranged to be retract within the second segment. In this instance the fastening means may be arranged to secure the first segment within the second segment.

Alternatively, the first segment may be detachable from the second segment.

The heel may be detachable from the shoe body. In this instance the heel may be provided with a clip which attaches to a fastening means on the shoe body.

According to a second aspect of the present invention there is provided a heel for a shoe comprising a first segment including a fastening means arranged to engage with a fastening means on a second segment the fastening means arranged such that the length of the heel can be altered.

Figure 1 illustrates a basic shoe 10 having a shoe body 12 and a heel 14. The body of the shoe comprises a sole and an upper body. The shoe body 12 and heel 14 may be shaped in any appropriate way.

Figure 2 illustrates a first embodiment of the present invention. In this embodiment the heel of the shoe 14 is provided with two or more segments 16, 18, 20 as shown in Figure 2a. The segments, 18, 20 in Figure 2 are shaped such that one segment 18 may be manipulated such that it is inside a second segment 20 as shown in Figure 2b.

Preferably, the segments 18 and 20 are provided with suitable fastening means, not shown.

The fastening means will act to prevent the first segment 18 from freely moving in and out of the second segment 20. This is required so that the heel may be secured in position when the first segment 18 has been retracted into the second segment 20 as shown in Figure 2b.

Additionally, the segments should also be provided with fastening means that enables the segments 18 and 20 to be secured in the extended state shown in Figure 2a.

The fastening means could be any suitable means for securing the segments in position in a manner that will support the weight of a person using the shoes. The fastening means may be, for example, a clip fastener comprising a projection on one segment and a complimentary depression on the other segment which receives the projection when the segments are in the appropriate configuration.

In the second embodiment of the invention the heel may be extended or shortened by adding or removing segments as appropriate. The segments are provided with fastening means. The fastening means for the second embodiment enable segments to be detached from each other thereby elongating or shortening the heel.

The fastening means may be any suitable fastening means. For example, the fastening means may be a screw thread. The first segment may therefore have a screw thread on the outside of one end and a second segment may have a complimentary screw thread on the inside of one end. If the screw threads on the first and second segments are arranged to engage to hold the first and second segments together then the segments may be attached, to lengthen the heel, and detached, to shorten the heel, as required.

Alternatively the fastening means may be a clip mechanism with one segment having a projection and a second segment having a depression arranged to receive the projection.

Figure 3 illustrates a third embodiment of the present invention. In the third embodiment the shoe heel 14 is provided with hinging means 22 between a first 24 and a second 26 segment. The hinging means 22 enables the second segment 26 of the heel 14 to rotate between a first position, illustrated in Figure 3a, where the heel 14 is extended and a second position, illustrated in Figure 3b, where the height of the heel 14 is reduced.

The hinging means 22 may be any suitable means enabling the second segment 26 to rotate around an attachment point between the first 24 and second 26 segments. For example it may be,... Preferably, the first 24 and second 26 segments are also provided with means for securing the heel in its extended state. For example, the segments may be provided with complimentary magnets.

The second segment 26 of the heel 14 may either rotate so that the first 24 and second 26 segments are adjacent to each other as shown in Figure 3b. Alternatively, the second segment may only rotate partially as shown in Figure 3c. If the second segment 26 only partially rotates then the first segment 24 should be provided with a recess into which a second segment portion adjacent to the first segment 24 can be received.

Figure 4 illustrates a fourth embodiment of the invention. In Figure 4 the attachment between the shoe heel 14 and the shoe body 12 is provided with a hinging means 28. The hinging means 28 may be any suitable means which allows the shoe heel 14 to rotate relative to the shoe body 14 between the extended state shown in Figure 4a and the recessed state shown in Figure 4b. Preferably, the first 24 and second 26 segments are also provided with means for securing the heel in its extended state, illustrated in Figure 4a.

For example, the segments may be provided with complimentary magnets The shoe body 12 is provided with means for receiving the shoe heel 14, for example a recess 30. When a user wishes to convert a high heeled shoe to a flat shoe they rotate the shoe heel 14 around the hinging means 28 until it is held within the recess 30. Any suitable means, for example, magnets or a clip fastener, may be used to secure the shoe heel 14 within the recess 30.

Finally, if desired the heel may be made completely detachable. This may be done using any suitable means. For example, the heel may be provided with a projection, as shown in Figures 3a and 3b, where the projection is received by a suitably shaped receiving means as illustrated in Figures 4a and 4b respectively.

It is preferable that the sole of the shoe is sufficiently flexible that the shoe can easily transition between the shape required for the sole of the flat shoe and that of a high heeled shoe.
