1. Field of the Invention
This invention relates, generally, to a traction device for footwear. More particularly, it relates to a traction device having a pliable securing portion configured to conform around a user's footwear.
2. Background Art
Traction devices for footwear currently being manufactured can span the length of the outsole of a shoe. The Yaktrack Walk Traction system has a securing portion connected to the perimeter of a shoe and has a traction portion being a metal coil overlapping a length of thermal plastic elastomer material covering a substantial portion of the outsole of a shoe. When the traction portion spans the entire length of the outsole of a shoe, it requires more material to manufacture, which can be costly. Additionally, damage can occur to the perimeter of a shoe when the securing portion of a traction device rubs against the shoe material. Thus, there is a need for a traction device that can be connected to a portion of a user's footwear without having to be in contact with the entire perimeter of a shoe.
Currently, Kako Icetrekkers Traction System, Diamond Grip can be attached to the perimeter of a shoe with a rubber harness. This system utilizes a plurality of steel alloy projections connected to a cable configured to overlay the heel portion and the forefoot portion of the outsole of a shoe. This traction device can be bulky and heavy for a user to walk with which may result in a user tripping and become injured. It would be more desirable for a traction device for footwear to be lighter in weight and less bulky.
However, in view of the prior art considered as a whole at the time the present invention was made, it was not obvious to those of ordinary skill in the pertinent art how the identified needs could be fulfilled.
The long-standing but heretofore unfulfilled need for a traction device having a pliable securing portion configured to connect the traction device to footwear and a traction portion forming a barrier between a portion of the outsole of footwear and a walking surface which also includes improvements that overcome the limitations of prior art traction footwear covers is now met by a new, useful, and non-obvious invention.
In a preferred embodiment, a traction device for footwear has a pliable securing portion with a primary end having a primary opening located opposite a secondary end having a primary opening. The primary opening of the primary end of the securing portion forms a primary compartment. The primary opening of the secondary end of the securing portion forms a secondary compartment. At least one traction portion has a primary end located opposite a secondary end, whereby, at least one traction portion has a plurality of connected links.
A wall surface of the primary compartment has an opening configured to receive a portion of at least one link. A wall surface of the secondary compartment has an opening configured to receive a portion of at least one link. A primary retainer has a primary retainer end located opposite a secondary retainer end. It is within the scope of this invention for the retainer end to be removable. The primary retainer is configured to be retained by the primary compartment, whereby, a portion of at least one link is configured to connect to the primary retainer within the primary compartment when a portion of at least one link is received by the at least one opening in the wall surface of the first compartment.
A secondary retainer has a primary retainer end located opposite a secondary retainer end. The secondary retainer is configured to be retained by the secondary compartment. A portion of at least one link is configured to connect to the secondary retainer within the secondary compartment when a portion of at least one link is received by the at least one opening of the wall surface of the secondary compartment.
In an alternate embodiment, the novel traction device can have a securing portion having an adjustable attaching element connected thereto. An attaching element includes, but is not limited to, a hook and loop attachment, a latch, a button, or a clasp. A user can tighten or loosen the traction device for installation or removal of the traction device on footwear.
In another embodiment, the novel traction device can have at least one traction portion configured to be removable from the traction device. At least one retainer end is removable. When the retainer end has been removed, the retainer can then receive a replaceable traction device or a traction portion can be removed from the traction device. The traction device can have a single traction portion. A traction device includes, but is, not limited to, a plurality of links. A user can add additional traction portions to the traction device for an increase in traction. The wall surface of the compartments can have a plurality of openings to accommodate a plurality of traction portions being added to the retainer.
For a fuller understanding of the nature and objects of the invention, reference should be made to the following detailed description, taken in connection with the accompanying drawings, in which:
In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings, which form a part hereof, and within which are shown by way of illustration specific embodiments by which the invention may be practiced. It is to be understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the invention.
In a general embodiment, novel traction device 1 has pliable securing portion 3 configured to conform around footwear including, but not limited to, a shoe or a boot. A retainer 5A and 5B is connected to each one of securing portion 3. Retainer 5A and 5B can include, but is not limited to, a threaded rod, a screw, or a rod. Retainers 5A and 5B each have a retainer end 6A and 6B. A retainer end includes, but is not limited to, a nut, a locking nut, a screw head, or a clamp. The retainer ends 6A and 6B each retain a portion of link 7 of traction portions 4A and 4C onto retainers 5A and 5B. Each end 13 and 14 of securing portion 3 each has a pocket having an opening that receives a retainer. At least one retainer end can be removable during installation of the replaceable traction portions.
At least one opening 8A and 8B is located on an end portion 13 and 14 of securing portion 3. Opening 8A and 8B are configured to receive a portion of link 7 of traction portion 4B configured to receive retainer 5A and 5B, thereby, retaining retainer 5A and 5B within primary and secondary end portions 13 and 14.
In a preferred embodiment, a plurality of replaceable traction portions 4A, 4B, and 4C each having a plurality of links are retained by removable retainers 5A and 5B. The traction portions include, but are not limited to, plumber's chain. Each link 7 has a flattened link portion 9 having an opening 11 located opposite a protruding link portion 12 having an opening. The flattened link portion 9 and the protruding link portion 12 are connected at an end of flattened link portion 17.
It is within the scope of this invention for the traction portions to be removable and replaceable from the retainer when at least one removable retainer end is removed from the retainer. Additional traction portions can be added to retainers 5A and 5B for more traction. It is within the scope of this invention for the wall surface of the compartments of the securing portion to have more than one opening to receive a portion of at least one link, allowing the link to connect to a retainer retained within the compartment. For example, a user can use a quantity of five (5) traction portions (not shown) when a user is walking on slippery surfaces such as ice, snow, oil or grease. Tractions portions can be individually replaced if they become damaged from corrosion or if the links become deformed.
Construction of the Novel Traction Device
It will now be seen, referring to
Portable traction device 1 is compact and can easily fit into a pocket (not shown) of a user's garment (not shown). When traction device 1 is worn around shoe 2, a user can safely transition from a slippery surface such as ice to another surface such as pavement resulting from the non-bulky and light weight features of novel traction device 1.
It will thus be seen that the objects set forth above, and those made apparent from the foregoing description, are efficiently attained. Since certain changes may be made in the above construction without departing from the scope of the invention, it is intended that all matters contained in the foregoing description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
