DE4128704A1 - Shoe ventilation system with hole - has hole closed by leather flap on which is hooked pile fastening, or incorporates slide mechanism in three parts. - Google Patents

Abstract

The shoe-ventilation system consists of a hole (3) closed by a leather flap (1) on which is a hooked-pile fastener (2). Alternatively the shoe incorporates a plastics slide mechanism is three parts. The slide moves in a housing made of two parts and has openings in particular parts of it. A plastics turning mechanism consists of three parts and is inserted into the shoe. One of the two parts incorporates a circular housing containing a rotary circular slide which has openings in at particular points. USE/ADVANTAGE - The ventilated shoe enables the foot to breathe when hot, through holes which can be closed in wet weather.

Description

State of the art

With conventional footwear one has two variants: firstly the so-called "closed" footwear, on the other Shoes with "permanent" ventilation openings (e.g. sandals).

Criticism of the state of the art

Disadvantage of the above Execution is that the foot is hot in a warmer climate become and can no longer breathe (especially when doing sport), whereas the second type of footwear (e.g. in the rain) cannot be closed, d. H. is waterproof, and the foot offers little support.

problem

The specified in the claim The invention has the following problems based on:

• - Often during sporting activities sturdy, sturdy footwear needed, but still in summer Climate sufficient ventilation as required offers.
• - Fashion: Sneaker wearers should be theirs Can follow trend without following the Advantages of "open" shoes (like e.g. B. sandals).
• - Orthopedically important foot breathing and -Ventilation is intended for all types of Footwear must be guaranteed.

Achievable advantages

The advantages achieved with the invention consist in particular in that a shoe is created with their application largest possible and not yet achieved Climate adaptability. Wearable by Winter to summer all year round, also at Rain (closable almost watertight). Because it can be fashioned universally (and since the invention of any kind of "closed" footwear use can find) an immensely large one Address target group with it (more commercial Advantage).  

Further embodiment of the invention

1. Since different regions of the shoe (e.g. toe, side,...) can be used to install a ventilation system, of course, its shape must be adapted to its location.

2. Three types of embodiment of the invention are possible (see also Claims):

• a) the leather flap with Velcro over a permanent Opening in the shoe,
• b) the sliding mechanism,
• c) the rotating mechanism (which is just a special type of sliding mechanism represents).

Description of the three exemplary embodiments

The exemplary embodiments of the invention are shown in the drawings and are described in more detail below:

It shows

• - The drawing 1a) the first embodiment, namely the leather flap sewn on the side of the shoe (1a): 1 ).
  It can be used to close (partially or entirely) the ventilation openings (1a): 3 ) in the shoe sidewall using a Velcro fastener (1a): 2 ).
  In this example, the leather flap is sewn onto the shoe only on its narrow front.
• Drawing 1b) the same embodiment as 1a), with one difference that the leather flap is not on their narrow front, but on their top (slightly inclined here) is attached.
• - The drawing 1c) the same design as 1a), with the difference that here both the leather flap (1c): 1 ) with Velcro (1c): 2 ) and the ventilation openings (1c): 3 ) underneath the shoe sidewall, but on the top of the shoe near the toe.

It shows

• - The drawing 2a) the second embodiment, namely the sliding mechanism attached to the side wall of the shoe, consisting of a plastic slide (2a): 1 ) which is guided in a housing from two joined parts (2a): 2 ) and (2a): 3 ) becomes. The slide (2a): 1 ) has a handle (2a): 4 ) which protrudes through the outside of the slide housing (2a): 3 ) (through the handle opening (2a): 5 ) and is therefore freely accessible from the outside. With this handle (2a): 4 ) you can now bring the slide (2a): 1 ) into such a position within the sliding housing that the ventilation openings (2a): 6 ) of the slide with the ventilation openings (2a): 7 ) cover the valve housing so that air can pass through, ie the shoe is ventilated in this way. On the other hand, the slide can be moved to another position using the handle (2a): 4 ), in which the ventilation openings (2a): 6 ) of the slide are closed by the slide housing (2a): 2 ) and (2a): 3 ) , and vice versa the ventilation openings (2a): 7 ) of the slide housing (2a): 2 ) and (2a): 3 ) are covered and closed by the slide, ie the shoe is tight (against water and cold) and closed.
  To attach this mechanism to the shoe, a hole the size of the slider housing must be provided in the shoe side wall so that the slider housing can be attached (e.g. glued) there. The same applies to Examples 2b) and 2c)!
  All three parts (2a): 1 , 2a): 2 and 2a): 3 ) of the mechanism can be made of the same material (plastic).
  (This also applies to Examples 2b) and 2c).)

It shows

• - The drawing 2b) the same design as 2a), with the difference that here the ventilation mechanism, consisting of slide housing (2b): 1 ) and slide (2b): 2 ), not on the shoe side wall, but on the shoe top in near the toe.
  Function, manufacture and material are analogous to example 2a), only the shape is of course adapted to the changed position on the shoe.
• - the drawing 2c) a ventilation mechanism, consisting of a turntable (2c): 1 ) and a rotating housing (front and rear / 2c): 2 ), which is based in principle on the same system as example 2a). The difference to example 2a) is that the slide (2a): 1 ) from example 2a) is not slidable but rotatable, so it corresponds to the turntable (2c): 1 ). This is guided in the rotary housing (2c): 2 ), which corresponds to the slide housing from Example 2a) (2a): 2 / 2a): 3 ).
  The turntable is rotated with the help of the rotary handle (2c): 4 ), which protrudes through the rotary handle opening (2c): 5 ). If the turntable is now turned in its rotating housing so that its ventilation openings (2c): 6 ) coincide with the ventilation openings (2c): 7 ) of the rotating housing (2c): 2 ), air can pass through.
  The mechanism can also be closed by turning the turntable so that its ventilation openings (2c): 6 ) are covered by the rotating housing and conversely the ventilation openings (2c): 7 ) of the rotating housing are closed by the turntable.

Claims (2)

Generic term:
Ventilation systems for shoes that can be closed (quasi waterproof) depending on the weather (in 3 versions), Characteristic part:
