Abstract

Door closing system in coin selectors in coin selectors consisting of two walls, one of which rotates with respect to the other on an axis (3) and has a spring (4) of type V without turns. The doors have two stable equilibrium positions: open and closed. When the mobile door (2) is opened, the spring (4) exerts a force tending to close it until it reaches an unstable equilibrium position from which the spring tends to open the door until it is brought to its stable opening position. An analogous process occurs when the mobile door (2) is closed. This system allows the channel to be cleaned when the door is open and in stable equilibrium.

Description

Door closing system in selectors coins

Technical sector

The present invention falls within the field of coin operated machines, more specifically in coin selectors and systems to channel the coins

Prior art

An important conditioning factor in the design and manufacture of coin selectors, as is the case with 3.5 '' format coins, is the need for one of the walls from the channel in which the coin moves can be extracted:

to)

for release possible unblocking; in this case a mechanism in the box of the selector opens the wall a few degrees

b)

for cleaning: in which case the wall must be completely removed to facilitate this work.

Generally this is achieved by turning this wall in a door that rotates on an axis. A spring between this door, the shaft and the other wall closes the system at rest. This spring must withstand high tension to get the Channel width is maintained for the life of the appliance.

Explanation of the invention.

The door spring system presented in This invention has two great advantages over selectors current.

to)

when the door exceeds a certain angle, the spring function changes by opening the selector instead to close it, which greatly facilitates cleaning as it stays open alone, unlike other selectors that always they close.

b)

he Spring is a low cost and simple element.

The object of this invention is therefore in two bodies or walls, one fixed and one that moves with respect to the fixed through an axis and with the help and resistance, according to the case, of a V-shaped spring without turns. The fixed body has box shape with a top opening, a hollow space and a base. At the end opposite the opening of the fixed body is find a notch to which the end of the spring is attached, the other end of the spring being attached to the end of the body or movable wall by another notch or fixation.

When the device is closed both bodies they are in equilibrium position since the force exerted by the Spring tends to unite both.

When the door is opened, the mobile body, and in the opening process, the V-spring exerts in principle a force tending to close the movable wall until the imaginary diagonal that joins the ends of the spring coincides with the axis on which the mobile body rotates. At this time, the door is in a state of unstable equilibrium and any moving wall movement will have the effect that the spring exert a force tending to open or close the door further.

Therefore, if the door continues to open, the spring will tend to open the mobile door since the line is imaginary that joins the ends of the spring in front of the shaft. The door, it tends to open by itself until it reaches the position stable opening, where the angle that forms said line forms an angle almost perpendicular to the wall of the fixed body.

The fixings or notches of the spring are designed and placed in a certain position to achieve a desired angle of equilibrium, which will match the imaginary line that joins the ends of the spring with the axis on the one who turns the mobile door.

Detailed exposition of an embodiment of the invention

As shown in the figures, the object of this invention consists of two bodies or walls, one fixed (1) and another mobile (2) that forms the walls of the canal where they pass the coins in the selector. Both bodies are united through a shaft (3) and a V-shaped spring (4) without a spire. The body fixed (1) is box-shaped with a top opening (9), a hollow space (10) and a base (7). At the opposite end of the opening (9) of the fixed body is a notch (5) to the which joins the end of the spring (4), the other end of the spring (4) attached to the body or movable wall (2) in the notch (6).

When the device is closed, figures (1) and (2), the two bodies (1) and (2) are in equilibrium position already that the force exerted by the spring (4) tends to unite both bodies being the imaginary diagonal (11) that joins the ends of the spring and that is obtained by drawing a line between the two notches (5) and (6) in a position inside the shaft (3) forming an acute angle to the wall (12). That is, the imaginary diagonal stroke (11) is located between the axis (3) and the face (12) of the fixed wall (1).

When the door is opened, the moving body (2) and in the opening process, the spring (4) exerts in principle a force tending to close it as long as the imaginary diagonal (11) that joins the two ends of the spring is find in an internal position the axis (3), that is between the shaft (3) and face (12) of the fixed wall (1) as shown in figures (1) and (2). However, when the diagonal imaginary (11) that joins the ends of the compass spring by the axis (3), figure 3, the closing force of the spring is annulled with the another force of the spring (4) that tends to open the door (2), leaving the door (2) in a state of unstable equilibrium.

If the door (2) continues to open, it it tends to open as long as the imaginary line (11) is located between the axis (3) and the face (8) of the fixed wall (1). Is that is, the spring (4) exerts a force on the wall (2) tending to open it as long as the imaginary line (11) is located between the axis (3) and the face (8) of the fixed wall (1) until reaching the stable position shown in figures (4) and (5), in where the angle formed by said line (11) forms an angle almost perpendicular to the face (12) of the fixed body (1).

The spring fixings are designed to Get a desired balance angle. Balance angle it is the one that is formed by passing the imaginary line (11) that joins the spring ends (3) with the shaft (4). In our case, it is convenient that the angle of balance is between 45º and 60º to that does not interfere with the unblocking mechanism that operates between 7th and 20th. This equilibrium angle is defined by the characteristics of the spring and the doors.

Finally, the force with which the Spring (3) will depend on its thickness.

Way in which the invention is applicable industrial

This invention is applicable in machines operated by coins or the like.

Claims (3)

1. Door closure system in selectors currency consisting of two walls, one fixed (1) and another mobile (2) with respect to the fixed one when turning on an axis (3) and having a spring (4) Type V without turns whose ends are included in the notches (5) and (6) of the fixed body (1) and in which the diagonal imaginary (11) that joins the ends of the spring (4) is between the shaft (3) and the face (12) of the fixed wall (1) when the device is closed. 2. Coin selector channel according to claim one characterized in that the V-spring (4) reaches an equilibrium state when the imaginary diagonal (11) that joins the ends of the spring (4) passes through the axis (3) that joins the two doors corresponding to an angle of rotation of the imaginary diagonal (11) between 45º and 60º with respect to the fixed door (1) so that when this angle is smaller, the spring (4) tends to close the door (2) and when he is older, he tends to open the door (2). 3. Coin selector channel according to claim one, characterized in that when the door (2) is fully open or closed, it is held in this position by the action of the spring (4).
