Definitions

  • the present invention regards a shoe tree for being inserted into a shoe (dress shoes, casual shoes, etc.).
  • the present invention relates to a shoe tree with a frame designed to keep the shape of the shoe and remove the moisture inside.
  • 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.
  • 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.
  • Patent document 0001 Korean Patent Publication No. 10-1445848
  • the primary purpose of the present invention is to solve the aforementioned problem as well as other problems.
  • Another purpose of the present invention is to provide a shoe tree with improved shape retention and ventilation by supporting the multiple horizontal frames against a vertical frame as a backbone under the shape of ribs.
  • the present invention may provide a shoe tree in which each of the aforementioned horizontal frames is shaped after a circular arc that is bent from both sides of the aforementioned vertical frame toward the bottom of the shoe, and that includes the multiple horizontal frames inserted into the front of the shoe; and a vertical frame designed to support each of the horizontal frames at predetermined intervals.
  • the body inserted into the shoe is made of a frame, thereby greatly improving air permeability as well as shape retention.
  • 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.
  • FIG. 3 is a cross-sectional view cut along line 3 - 3 of FIG. 1 .
  • FIG. 4 is a cross-sectional view illustrating the separated first case and the second case cover of FIG. 3 .
  • FIG. 5 is a cross-sectional view cut along line 5 - 5 of FIG. 1 .
  • FIG. 6 is a cross-sectional view illustrating the separated first case and the second case cover of FIG. 4 .
  • FIG. 7 is a perspective view illustrating the separated first case cover of the first case.
  • 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 ) may include multiple horizontal frames ( 10 ) and a vertical frame ( 30 ).
  • 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.
  • 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.
  • the multiple horizontal frames ( 10 ) may be made of polyethylene (PE).

  • the vertical frame ( 30 ) may extend in the longitudinal direction from the toe to the instep.
  • 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.
  • the vertical frame ( 30 ) may be injected together with the multiple horizontal frames ( 10 ).
  • 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.
