Abstract

A shoe tree for being inserted into a shoe, such as a dress shoe or casual shoe, has a frame designed to keep the shape of the shoe and remove the moisture inside.

Description

TECHNICAL FIELD

The present invention regards a shoe tree for being inserted into a shoe (dress shoes, casual shoes, etc.). In particular, the present invention relates to a shoe tree with a frame designed to keep the shape of the shoe and remove the moisture inside.

BACKGROUND

A conventional shoe tree is a foot-shaped frame for being placed inside a shoe, designed to preserve its shape. A dehumidifying agent may also be placed inside the conventional shoe tree to wick away moisture.
However, the conventional shoe tree is a foot-shaped frame with multiple ventilation holes. Accordingly, air flows from the outside to the inside of the frame through the ventilation holes or vice versa, but since the structure of the conventional shoe tree does not allow a proper circulation throughout the inside of the shoe, poor ventilation makes drying inefficient.

FIG. 1 and FIG. 2 are the perspective views from the top and bottom of the shoe tree according to an embodiment of the present invention. The shoe tree (1) according to FIG. 1 and FIG. 2 may be inserted inside the front of the shoe. The shoe tree (1) may include multiple horizontal frames (10) and a vertical frame (30).
Referring to FIG. 1 and FIG. 2 , the shoe tree may include multiple horizontal frames (10). The multiple horizontal frames (10) may be located at predetermined intervals from the toe (front) to the instep (rear). The multiple horizontal frames (10) are distributed in the shape of ribs, and thus, they may well maintain the shape of the shoe and offer excellent air permeability. Each of the horizontal frames (10) may be shaped like a circular arc bent toward the sole of the shoe. For example, each of the horizontal frames (10) may be shaped after a hoof as they are closer to the instep. An outline of the multiple horizontal frames (10) may be shaped like a cone in plan view. The multiple horizontal frames (10) may be made of plastic. For example, the multiple horizontal frames (10) may be made of polyethylene (PE). In this case, the multiple horizontal frames (10) may sustain a small elastic deformation. As for the multiple horizontal frames (10), 8 plate-shaped frames may be arranged at predetermined intervals.
The multiple horizontal frames (10) may include the first to eighth horizontal frames (11 to 18). The first horizontal frame (11), which is the frontmost one among the multiple horizontal frames (10), may be shaped like a plate. An air passage (11 a) may be formed in the first horizontal frame (11). The air passage (11 a) may be shaped like an undercut groove. The first horizontal frame (11) may be shaped like a comb in a front view.
Referring to FIG. 1 and FIG. 2 , the vertical frame (30) may extend in the longitudinal direction from the toe to the instep. For example, the vertical frame (30) may extend in a shape similar to the instep. The vertical frame (30) may support the upper end of each of the horizontal frames (10) from both sides. For example, the vertical frame (30) may be injected together with the multiple horizontal frames (10). In addition, the multiple horizontal frames (10) may be assembled with vertical frame (30) to provide support. The vertical frame (10), like the multiple horizontal frames (10), may be made of polyethylene (PE).
The vertical frame (30) may include a hook (35). The hook (35) may extend in the longitudinal direction from the rear end of the vertical frame (30). The hook (35) may be shaped like a hook. The hook (35) may be hung on a clothesline or a hanger to dry the shoes in the sun. The hook (35) may be stored hung or used as a handle.
The forefront of the vertical frame (30) may have a front protrusion (31). The front protrusion (31) may protrude forward farther than the first horizontal frame (11). The front protrusion (31) may be the first part to touch the front of the inside of the shoe. Then, the air passage (11 a) of the first horizontal frame (11) will not be blocked, thus contributing to the effective air circulation inside the shoe.
