The present disclosure is directed to a heel traction device that provides anti-slip protection to footwear such as shoes and boots.
Traction devices provide protection against slipping on surfaces having a low co-efficient of kinetic friction such as ice, snow and other wet surfaces. It is often dangerous walking, running and working in environments having snow and ice on the surface especially when the ground or surface has a grade or slope. Such activities can involve carrying heavy objects where one's vision is at least partially obscured.
Traction devices with spikes exist that attach to footwear. However, such existing traction devices are insufficiently flexible to allow the user to walk or run efficiently and comfortably. In addition, this lack of flexibility results in an inefficient contact of the traction spikes to the slippery surface thereby limiting the effectiveness of the traction device. There is therefore a need for a traction device that is flexible, and which permits efficient contact of the bottom surface of the traction device with the ground surface when coupled to a user's footwear.
The present disclosure is directed to a flexible heel traction device which is configured to attach to the heel of an item of footwear such as a shoe or boot. The heel traction device as attached to the heel of a shoe or boot has traction elements which are preferably spikes as part of a spike assembly that engage the ground to provide improved traction. The flexibility of the heel traction device and the inclusion of a separate strap, preferably a Velcro strap, that is preferably received in slots formed in the heel traction device permits the traction elements to contact and grip the ground efficiently in harnessing the user's weight transfer.
According to one aspect of the present disclosure, there is provided a heel traction device for attachment to a heel of a shoe or a boot comprising a traction platform formed of a flexible rubber material. The traction platform has a first face for contacting a ground surface and a second face for attachment to the heel of the shoe or boot. The traction platform defines a plurality of openings formed therethrough for receiving a traction element in each of said openings. The heel traction device also has a support band connected to the traction platform for securing the traction platform to the shoe or a boot. The support band has a rear portion for attachment to a rear portion of the shoe or the boot and two opposing side portions for attachment to side portions of the shoe or the boot. Each of said side portions defining a slot formed therethrough for receiving a strap. The strap that is received in the slots is separate from the support band and is preferably a Velcro strap.
Additional features and advantages of the present invention will become apparent to those skilled in the art upon consideration of the following detailed description of the illustrative embodiments exemplifying the best mode of carrying out the invention as presently perceived.
The detailed description of the drawings particularly refers to the accompanying figures in which:
The embodiments of the invention described herein are not intended to be exhaustive or to limit the invention to precise forms disclosed. Rather, the embodiments elected for description have been chosen to enable one skilled in the art to practice the invention.
With reference initially to
The heel traction device 1 comprises a traction platform 4 having a first face 6 for contacting a ground surface, as shown in
The heel traction device 1 also comprises a support band 10 connected to the traction platform 4 for securing the traction platform to a shoe or a boot. In the embodiment shown in
The traction platform 4 and preferably also the support band 10 is constructed of a flexible rubber material. Preferably, the rubber material has the following composition as set out in table 1 below.
The content of the components of the rubber composition was measured by Fourier Transform Infrared Spectrometer.
The hardness of the rubber composition forming the traction platform 4 and the support band 10 is 43.5 on the Shore A hardness scale, as measured by a Shore A Durometer apparatus.
The thickness of the traction platform is preferably about 6.5 mm. The thickness of the support band is preferably about 2.45 mm.
As shown in
As shown in
As shown in
An alternate embodiment 50 of the heel traction device is shown in
The alternate embodiment 50 of the heel traction platform is composed of the rubber material described above and summarized in table 1.
The heel traction device is constructed according to methods known in the art such as injection molding involving the injection of a hot polymeric material into a cold mold. Preferably, the heel traction device is constructed using compression molding machines. The raw material is weighed and cut to size to fit into the mold. The temperature is carefully monitored to be consistent with the cycle time required to flow the material to all portions of the mold. Once the cycle is complete, the operator uses compressed air to cleanly lift the molded part out of the tooling by hand.
Injection molding techniques that extrude material over an existing core plate in the mold to provide a unitary construction may also be employed.
In operation, each of the heel traction device 1 and the alternate embodiment 50 may be attached to footwear such as the boot 2 at the heel 26 as shown in
Although the invention has been described in detail with reference to certain preferred embodiments, variations and modifications exist within the spirit and scope of the invention as described and defined in the following claims.
