Description

Self-closing apparatus with multi elasticity body

The present invention relates to an automatic closing device provided with multiple elastic bodies.

In general, furniture, refrigerators, and various sorting boxes are provided with a receiving body for storing and storing the objects by opening and closing. The housing is slidably coupled with the main body and the sliding device so as to slide in order to smoothly open and close. Conventional sliding devices are arranged in the main body of the furniture, refrigerator, and various organizers so as to slide on both sides of the inside of the space where the housing is inserted and on both sides of the housing.

In the conventional sliding device, a fixed sliding body is installed at a position facing each other inwardly in which the housing of the main body slides, and a movable sliding body is installed at a position coupled to the fixed sliding body on both sides of the housing, and the fixed sliding body It is disposed between the movable sliding body and is provided with a sliding body for rolling movement so that the movable sliding body is slid when the housing moves. The enclosure is slid with a small force by a sliding device provided with a rolling body to improve the operation convenience.

A conventional sliding device is installed to be opened and closed while the housing is slid. When the housing is closed, the sliding body is inserted into the space of the main body while being closed by the sliding device when the user applies a force in the closing direction.

If the user applies a force less than the force required to close the enclosure, the enclosure will not be completely closed but should stop in the open position and apply a closing force again. In addition, if more force is applied than necessary force, the impact repulsive force due to the impact in the direction of the sliding device is generated after the closing and reopened, so that the open enclosure must be closed again. Therefore, it is difficult for the user to close the operation at a time with an accurate closing force, and when a large amount of force is applied, a shock is generated in the housing and the sliding device, thereby reducing the service life.

Recently, an automatic closing device that maintains a closed state by being automatically closed by elastic force and is capable of being opened and used is mounted on a sliding device.

The conventional self-closing device is provided at a position at which the housing is closed on the surface on which the movable rail slides on the fixed rail of the sliding device. The self-closing device is installed on the sliding surface of the fixed rail that the moving rail is supported to slide so that the moving rail is kept closed by elasticity in the closed position, and when the moving rail moves to the open position, the elastic body is tensioned.

In addition, the fixed sliding body is installed in the sliding frame may be provided with an automatic closing device that can be automatically closed in accordance with the movement of the movable sliding body. Conventional self-closing device is installed on the fixed sliding body on the surface to which the moving sliding body is moved, coupled with the movable sliding body sliding with the enclosure, and is automatically closed by elastic force, and has a structure in which the latch is released when opened. .

However, the conventional sliding device provided with the automatic closing device has a problem that it is difficult to control the elastic force because the elastic body having an elastic force acting as the automatic closing force at the time of automatic closing is formed of a single member. That is, the operation of automatically closing the receiving body is automatically operated by the elastic force generated while the tensioned elastic body is restored, so in order to adjust the elastic force, the user should replace the elastic body having the desired elastic force. Accordingly, when the elastic body having a strong elastic force is used to increase the closing force that is automatically closed, the user has to work in the open position while tensioning the elastic body having a strong elastic force at the time of pulling out the enclosure, so that the drawing is difficult. In addition, when an elastic body having a weak elastic force is used for soft drawing, the drawing of the housing is easy, but the automatic closing function is lowered, so that the closing operation is stopped without being completely closed.

The locking moving body 121 is positioned in the linear guide portion 113a when the guide wall 113 is inserted into the guide groove 124 and the closing body 2 is closed. The opening direction of the housing body 2 is lowered while being inserted into the curved guide portion 113b along the straight guide portion 113a in a state in which the driving body 4 is engaged with the 122. The locking groove 122 of the locking movable body 121 in which the opening direction of the housing 2 is lowered may be moved to the opening position while the opening direction of the locking groove 122 is opened. When the closing is performed again, the driving body 4 is engaged with the locking groove 122 in accordance with the movement of the housing 2, and the locking moving body 121 moves from the curved guide portion 113b to the linear guide portion 113a. You are guided through.

In addition, the locking moving body 121 has an inclined surface 121a inclined upward in the opening direction of the locking groove 122 at the center of the receiving body 2 in the opening direction. The inclined surface 121a minimizes the interference of the driving body 4 inserted into the locking groove 122, and the driving body 4 is fixed to the locking groove 122 when the linear guide portion 113a is elastically deformed after a malfunction. The inclined surface is formed to be easily inserted. That is, when the driving body 4 is inserted in the malfunctioning position, the linear guide portion 113a descends so that the linear guide portion 113a is elastically deformed through the inclined surface 121a so as to minimize the interference. Inserted and engaged.

In addition, an elastic coupling groove 123 in which one side of the elastic member 125 is fixed is formed at the lower end of the closing portion of the housing 2 of the locking moving body 121.

The elastic means 125 is elastically connected between the locking movable body 121 and the closing body 111, and a plurality of elastic bodies 125a and 125b are connected in series. One side of the elastic means 125 is inserted and coupled to the elastic coupling groove 123 of the locking moving body 121, the other side is fixed to the elastic fixing groove 114 of the closing body 111. The elastic means 125 is tensioned when the locking moving body 121 moves in the opening direction from the closing direction of the housing 2 to provide an elastic force. Resilient means 125 is a locking moving body 121 is inserted and fixed to the curved guide portion 113b in the open position of the housing (2) to maintain a tensioned state, the locking movable body 121 to the curved guide portion 113b When the housing 2 is moved to the closed position in the state where the driving body 4 is inserted into the locking groove 122 of the locking moving body 121, the driving body 4 is automatically moved in the closing direction by the elastic force of the tensioned elastic means 125. It is closed.

In the elastic means 125, the primary elastic body 125a and the secondary elastic body 125b having different elastic forces are connected in series. The primary elastic body 125a and the secondary elastic body 125b connected in series are provided with elastic force while the locking moving body 121 is tensioned when moving in the opening direction in the closing direction of the housing 2. Here, a user who opens and operates a position where the primary elastic body 125a and the secondary elastic body 125b having different elastic forces are tensioned according to each tensile force at the time of tensioning may be recognized. That is, the primary elastic body 125a and the secondary elastic body 125b are simultaneously tensioned by the opening operation of the housing 2. At this time, the first elastic body 125a and the second elastic body 125b which are connected in series are easily opened and operated while the elastic body having a small elastic force is first tensioned, and the primary elastic body 125a and the secondary elastic body are finished when the small elastic body is opened. While the elastic body having a large elastic force is tensioned in the 125b, the locking moving body 121 is inserted into the curved guide portion 113b to maintain the tensioned state. Here, a larger force is required when the elastic body having a larger elastic force is tensioned after finishing the elastic body having a smaller elastic force. Therefore, the user who opens and operates the enclosure 2 can recognize the open position of the enclosure 2 as the in-output of the enclosure 2 is changed by the change of the elastic force.

That is, when the user pulls out the elastic bodies 125a and 125b in which the primary elastic body 125a and the secondary elastic body 125b are connected in series during the opening operation of the housing 2, each elastic body 125a and 125b is tensioned. The opening position can be recognized by recognizing the elastic force that is changed according to the distance, and when the opening position is recognized, the driving body 4 which the user moves together with the housing 2 is released from the locking moving body 121. Can be recognized by the user to prevent injuries due to undesired automatic closing.

In addition, when the housing 2 is closed, the driving body 4 is engaged with the locking moving body 121 and is automatically closed by the force of the primary elastic body 125a and the secondary elastic body 125b having different elastic forces. That is, the elastic means 125, in which the primary elastic body 125a and the secondary elastic body 125b are connected in series, may be tensioned step by step according to each elastic force at the time of tension, and close operation by the force of each elastic force at the time of automatic closing. As this is done, the closing efficiency can be improved.

Accordingly, the primary elastic body 125a and the secondary elastic body, in which the elastic means 125, which is elastically coupled to the closing body 111, to the locking mobile body 121 to which the receiving body 2 is automatically coupled and closed, are different from each other. 125b is formed so that it may be connected in series. When the elastic means 125 is tensioned when the enclosure 2 is opened, a difference occurs in the force with which the enclosure 2 is drawn out according to the difference in the elastic force, so that the enclosure 2 operates within the automatic closing device 100. The position can be recognized in the inside, and the position at which the enclosure 2 is released from the automatic closing device 100 can also be recognized. Thereby, the enclosure 2 can be operated smoothly while being aware of the position to the user so as to avoid unwanted automatic closure during the opening operation. In addition, when the housing 2 is operated in the closing direction, the driving body 4 is closed by the restoring force of the elastic means 125 while being engaged with the locking moving body 121. In this case, the elastic means 125 may be closed by the force of the primary elastic body 125a and the secondary elastic body 125b, so that the elastic means 125 may be automatically opened in the opened state and the elastic force is increased in the closed state. .

Here, the elastic means 125 in the present specification is connected to the primary elastic body 125a and the secondary elastic body 125b having different elastic forces in series, but for convenience of description. The elastic means 125 may have two or more elastic forces and may be connected in series. That is, the elastic means 125 may be used in series with three or four or more elastic means 125 having different elastic forces.

The connecting body 126 is disposed between the primary elastic body 125a and the secondary elastic body 125b, and each of the connection grooves 126a at one end where the primary elastic body 125a is fixed and at the other end where the secondary elastic body 125b is fixed, respectively. Has The connecting body 126 is disposed between the primary elastic body 125a and the secondary elastic body 125b so that the primary elastic body 125a and the secondary elastic body 125b can be connected in series, and the primary elastic body 125a in the connecting groove 126a. ) And the secondary elastic body 125b may be inserted and fixed in series. As the connecting body 126 connects the primary elastic body 125a and the secondary elastic body 125b in series, an elastic body having a small elastic force is formed in the primary elastic body 125a and the secondary elastic body 125b when the housing body 2 is tensioned. When the first elastic body 125a is tensioned and the small elastic body is tensioned and reaches a position where it can no longer move inside the closing body 111, the primary elastic body 125a can no longer be tensioned, and the secondary elastic body 125b is tensioned. Can detect the sudden difference in tensile force. Therefore, as the primary elastic body 125a and the secondary elastic body 125b are connected by the connecting body 126, the series elasticity of the elastic bodies 125a and 125b can be easily connected in series, can be firmly connected during operation, and the elastic force is different. The difference in the tensile force according to the tension of the elastic body (125a, 125b) is provided so that the user can be surely recognized.

Here, the connecting body 126 in the present specification is provided to be connected in series between the primary elastic body 125a and the secondary elastic body 125b, and one is provided so as to be connected in series with each of the two elastic bodies 125a and 125b. This is for convenience of description. That is, the connecting body 126 may be installed at positions connected in series according to the number of elastic bodies that may be arranged in plurality of two or more, and two connecting bodies at respective positions connected to three elastic bodies. 126 is used, and four connectors 126 may be used. In other words, it is apparent to those skilled in the art that the quantity of the connecting body 126 can be adjusted according to the quantity of the elastic means 125 connected in series.
