Description

  The present invention relates to a device for closing an opening / closing member in an opening / closing device for a sliding door, in which the opening / closing member of the sliding door is held so as to be capable of relative movement (sliding or rotating) with respect to a fixed member. The present invention relates to an opening / closing member closing device having a buffering function configured to relieve the opening / closing sliding when the opening / closing member is closed by a tensile force with an elastic body such as a buffer.

Many of the opening / closing devices provided with the sliding door opening / closing portion include an opening / closing member closing device that closes the opening / closing portion while preventing the opening / closing portion from being roughly closed.
As this kind of device, it has a lock part attached to the side surface of the drawer and a retracting device attached to the side wall of the furniture exterior, and when the drawer is closed, the pin of the lock part is captured by the retracting device and the furniture There is known a closing device configured to move the drawer to a closed position, that is, a position in which the drawer is completely contained in the furniture by being drawn inward (see Patent Document 1).

  The closing device includes a housing, a carriage slidably provided in the housing, a cam attached to a front portion of the carriage, and a tension spring provided between the housing and the cam. Yes. A guide way (slit) for guiding a guide pin provided on the cam is formed in the housing.

  The guide way has a straight portion that guides the guide pin in the front-rear direction, that is, the moving direction of the drawer, and a bent portion that is bent at a substantially right angle from the front end of the straight portion, and when the drawer is opened, The guide pin moves from the straight portion of the guide way of the housing to the end (offset end) of the bent portion, whereby the cam is held at the front portion of the housing. At this time, the tension spring is in the most extended state.

If the drawer is to be closed from this state, the pin of the lock portion attached to the side surface of the drawer and the cam of the retracting device attached to the side wall of the furniture exterior are engaged, and the cam is pushed rearward to rotate. As soon as the guide pin of the cam is removed from the bent portion of the guide way and enters the straight portion, the cam in a state where the pin of the lock portion is captured is pulled backward by the tension spring together with the carriage, thereby moving the drawer. It is carried to the closed position which is the innermost part of the range.

    In order to be able to be used as a conventional sliding door closing device that can accommodate a heavier load, the pulling force must be increased. This is because if the size and weight of the sliding door are increased, the pulling force is insufficient with respect to the load of the sliding door including the contents, and the possibility that the sliding door is not completely closed increases.

    In the structure of the conventional closing device, when the sliding door is opened, that is, the guide pin provided on the cam is located at the end of the bent portion of the guide way of the housing, and the tension spring is in the most extended state. When pulling, the pulling force of the tension spring is all applied to the guide pin engaged with the end of the guideway.

    Therefore, if the structure of the conventional closing device is left as it is and the spring pulling force is increased, the cam, which is a small part compared to other parts, will be burdened with all that force. It must be used or a cam molded with a higher strength material must be used. When a large cam is used, the housing for slidably housing the cam must be increased in size, which makes it difficult to reduce the size of the apparatus. In addition, when a cam formed using a high-strength material is used, there is a problem that the manufacturing cost of the apparatus increases.

  The present invention has been devised in view of the circumstances as described above, and its object is to cope with an increase in the load of an opening / closing member such as a sliding door without increasing the size or cost of the device. An object of the present invention is to provide a closing device for an opening / closing member. In a sliding door opening / closing device in which the sliding door opening / closing member is held so as to be capable of relative movement (sliding or rotating) with respect to the fixed member, the opening / closing sliding member is closed when the opening / closing member is closed by a tensile force by an elastic body or a buffer. An object of the present invention is to provide a furniture such as a sliding door with an opening / closing member closing device having a buffer function configured to relieve movement.

  In order to achieve the above object, in the sliding door opening / closing rail formed by holding the opening / closing door movably with respect to the fixed rail portion of the sliding door in the sliding door furniture, a guide pin and a protruding guide pin are provided at the lower portion of the sliding door and at the upper portion of the door. Attaching and fixing the guide pin to the top plate, attaching the capture rail part, the projection guide pin and the buffer part, and when the sliding door is closed, both guide pins pass through the capture rail part and the buffer guide pin It is the furniture with a buffer sliding door comprised so that the said sliding door might be closed by catching by a part and bringing about the buffer of opening and closing of a door.

There are 2 to 5 door cars attached to the lower part of the sliding door, and the diameter of the roll of the door wheel is 15 to 30 mm. Preferably, there are 2 to 3 door cars, and the diameter of the car is 20 mm to 30 mm. The guide pins installed on the upper part of the sliding door and the projecting guide pins are attached with a lower part to facilitate sliding up and down of the guide pins and buffer the contact with the catching rail.
The guide pins installed on the upper part of the sliding door and the projecting guide pins are attached with a lower part to facilitate sliding up and down of the guide pins and buffer the contact with the catching rail.

It is a hook part which can be engaged / disengaged with the member to be captured in a state where the sliding member is engaged with the fixing element. The to-be-captured member is elastically supported so as to be displaceable so as to be retracted following the surface of the capturing portion and then returned to be captured by the capturing portion.
The capture rail portion for sliding the guide pin is a member that can be engaged with and disengaged from the captured member in a state in which the sliding member is engaged with the fixed member. The protrusion guide pin buffering part is a sliding door storage furniture with a buffering function that is elastically supported so as to be displaceable so as to return after being retracted following the surface of the guide pin capturing part and to be captured by the capturing part.

According to the opening / closing member closing device of the present invention configured as described above, the sliding member is guided in the expansion / contraction direction of the elastic body by the guided portion moving in the linear portion of the guide portion. When the guided portion moves to the guide portion, the sliding member and the fixed rail engage with each other, and when the guided portion moves from the rail portion of the guide portion to the straight portion, the sliding member and the sliding member interact with each other. Engagement is performed. The engagement and disengagement between the sliding member and the rail portion can be easily realized by the relative movement of the sliding member and the rail in a direction orthogonal to the contraction direction of the elastic body such as a spring.

According to the present invention, in the sliding door of the furniture, the closing device which is a buffering part at the opening and closing part is configured to receive all the pulling force of the elastic body by sliding without burdening the rail capturing part. It is possible to ease the opening and closing of furniture such as sliding doors against buffering of opening and closing of sliding doors, because it is not necessary to increase the pulling force and increase the catch of rails by increasing the pulling force by providing relaxation of opening and closing Therefore, it is possible to cope without increasing the size or increasing the price.
