Description

This patent application is a Continuation-In-Part application of U.S. patent application Ser. No. 16/124,201, filed on 7 Sep. 2018.

BACKGROUND OF THE INVENTION 1. Fields of the Invention 2. Descriptions of Related Art

There are many different types of hiking shoes that have different features for different trail conditions. Most of the trails in the forests have pebbles which can make conventional hiking shoes fail to protect the wearers because the pebbles reduce friction between the hiking shoes and the paths of the trails, especially in rainy days. Some hiking shoes have spikes protruding from the outsole such that the spikes bite into the soil and provide better friction. However, theses spikes cannot perform as desired because pebbles rolls and small in size, spikes cannot penetrate through the pebbles to grab the shoes in the trail paths. The pebbles are easily stocked between spikes to affect the effective length of the spikes so that the spikes cannot bite into the soil.

The present invention is intended to provide a hiking shoe that has anti-slip blocks, and spikes are embedded in some of the anti-slip blocks. Each spike includes specific grooves in the distal face thereof to provide better anti-slip features.

SUMMARY OF THE INVENTION

The present invention relates to a hiking shoe and comprises a vamp and an outsole. The outsole includes a rear section and a front section. The outsole has multiple anti-slip blocks formed thereto, and the anti-slip blocks are located at a distance from each other. Multiple spikes are respectively and integrally formed to a portion of the anti-slip blocks that are located at the rear section and the front section of the outsole. Each spike has an end face that is formed on the first end thereof, and the end face is in flush with the distal end of the anti-slip 16 corresponding thereto. The second end of each spike is located within the anti-slip block corresponding thereto and within the outsole. The end face of each spike has multiple grooves defined therein. Each spike is made by SKD-11 (Steel Kogu Dies-11). The grooves of the spikes are configured to provide friction.

Preferably, the front section of the outsole includes a first area and a second area. A bending line is defined between the first and second areas. The bending line is formed when a heel of the shoe lifts up. The anti-slip blocks that are located on the bending line each have one of the spikes.

Preferably, each of the spikes includes a head and a shank. Each of the anti-slip blocks that has the spike formed therein has a recess defined therein. The recess is defined in the outsole as well. The spike is integrally formed in the recess corresponding thereto. Each recess includes a large-diameter area and a small-diameter area. The small-diameter area is located in the anti-slip block and the outsole corresponding thereto. The large-diameter area is defined in the outsole. The head of the spike is formed within the large-diameter area corresponding thereto. The shank of the spike is formed within the small-diameter area corresponding thereto so as to prevent the spike from dropping off from the recess.

 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 to 7, the hiking shoe 1 of the present invention comprises a vamp 11 and an outsole 12. The vamp 11 is located above the top of the outsole 12 and connected along the periphery of the outsole 12. The vamp 11 includes an opening 14 and a trim portion 15, wherein the trim portion 15 is located along a portion of the opening 14. The opening 14 is configured to accept insertion of wearer's foot. The outsole 12 includes a rear section 131 and a front section 132. The outsole 12 has multiple anti-slip blocks 16 formed thereto, and the anti-slip blocks 16 are located at a distance from each other.

Multiple spikes 2 are respectively and integrally formed to a portion of the anti-slip blocks 16 that are located at the rear section 131 and the front section 132 of the outsole 12. The spikes 2 are integrally formed with the anti-slip blocks 16 so that the spikes 2 are not separated from the anti-slip blocks 16. Each spike 2 has an end face 20 that is formed on the first end thereof. The end face 20 is in flush with the distal end 160 of the anti-slip block 16 corresponding thereto. The second end of each spike 2 is located within the anti-slip block 16 corresponding thereto and within the outsole 12. The end face 20 of each spike 2 has multiple grooves 21 defined therein. In this embodiment, the grooves 21 are formed in a netted pattern. Each spike 2 is made by SKD-11 (Steel Kogu Dies-11). The grooves 21 of the spikes 2 provide friction when the grooves 21 are in contact with small rocks or pebbles so as to obtain anti-slip features. The SKD-II is an alloy that includes higher percentage of Carbon and Chromium, and has high stiffness and durable. The SKD-11 has great wear-resistant feature and has less deformation after being quenched. The hardness can reach to HRC58-62 degrees. The SKD-11 has acceptable price and is widely used as molds. The SKD-11 is one of the best alloy which is durable and not deformed. The crystals of the SKD-11 are fine and pure after secondary refining. Therefore, the spikes 2 made by SKD-11 allow the hiking shoes 1 to have better anti-slip function.

Specifically, the front section 132 of the outsole 12 includes a first area 1321 and a second area 1322. A bending line “A” is defined between the first and second areas 1321, 1322. The bending line “A” is formed when the heel of the hiking shoe lifts up. The anti-slip blocks 16 that are located on the bending line “A” each have one of the spikes 2. Each of the spikes 2 includes a head 22 and a shank 23. Each of the anti-slip blocks 16 that has the spike 2 formed therein has a recess 121 defined therein. The recess 121 is defined in the outsole 12 as well. The spike 2 is integrally formed in the recess 121 corresponding thereto during manufacturing processes. Each recess 121 includes a large-diameter area 122 and a small-diameter area 123, wherein the small-diameter area 123 is located in the anti-slip block 16 and the outsole 12 corresponding thereto, and the large-diameter area 122 is defined in the outsole 12. The head 22 of the spike 2 is formed within the large-diameter area 122 corresponding thereto, and the shank 23 of the spike 2 is formed within the small-diameter area 123 corresponding thereto so as to prevent the spike 2 from dropping off from the recess 121.

The rear section of the outsole 12 includes a third area 1311 and a fourth area 1312. A separation line “B” is defined between the third and fourth areas 1311, 1312. The separation line “B” passes through two of three spikes 2 and the two spikes 2 are located in the anti-slip blocks 16 of the rear section 131. The third area 1311 includes a flat section 133 and a curve section 134. The third one of the three spikes 2 mentioned above is located in the curve section 134. The two spikes 2 that the separation line “B” passes and the spike 2 that is located in the curve section 134 are located at three points of an imaginary triangle.

The three spikes 2 that form a triangle on the rear section 131 of the outsole 12 provide sufficient contact area with the ground. When the grooves 21 of the spikes 2 that are made by SKD-11 contact the rocks or pebbles, the spikes 2 do not slip so that the wearer wearing the hiking shoes 1 do not slip.

FIGS. 8 to 10 show another embodiment of the present invention, wherein the difference from the previous embodiment is that the end face 20 of each spike 2 has a notch 200 defined therein, and the grooves 21 extend radially from the periphery of the notch 200 and communicate with the notch. The notch 200 and the grooves 21 perform as a pawl to grab the rocks so that the wearer wearing the hiking shoes 1 do not fall even on slippery rocks.

When the rear section 131 contacts the trail path, the rear section 131 has the maximum contact area with the trail path, so that the three spikes 2 arranged as a triangle can obtain the best anti-slip feature. Furthermore, when the heel of the hiking shoe 1 is about to lift and the front section 132 of the hiking shoe 1 is about to contact the trail path, the spikes 2 on the rear section 131 prevent the wearer from slipping if the rear section 131 contacts pebbles. The spike 2 located at the curve section 134 ensure the walking in a stable status. The spikes 2 that are located at the three points of the triangle can ensure at least one spike 2 to contact the trail path in any situation.

While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
