Description

[Detailed description of the invention] The present invention suspends and supports a sliding door so that it can be moved in a direction perpendicular to the door face between a fully closed position and a position immediately before fully closed, and The present invention relates to a sliding door device having a guide groove formed in the guide groove and a guide mechanism that engages the guide with the guide groove to guide the lower part of the sliding door.

Although the device is a sliding door, it is possible to position the door in a flush state with a beautiful appearance in the closed state, and also to facilitate cleaning by eliminating the door guide groove at the bottom. is possible, and further, by the action of the guide mechanism,
It has advantages such as being able to prevent the door from rattling and also allowing the door to be opened and closed easily and without any damage to the door. However, in the conventional device, when the guide mechanism is fully opened, the guide mechanism is exposed in an upwardly protruding state, which defeats the purpose of facilitating cleaning and increases the risk of damage to objects or injury due to the guide mechanism. Ta.

For example, as described in Japanese Utility Model Application Publication No. 53-94823, the engagement structure between the guide groove and the guide at the lower end of the sliding door allows the movement path between the fully closed position and the position immediately before fully closed of the sliding door. Since the structure allows relative movement between the lower part of the sliding door and the guide in the direction of the door surface over the entire length, if the opening/closing operation force acts unevenly on the upper or lower side of the sliding door, the sliding door will be damaged. There is a risk that there will be a difference in the amount and direction of movement between the lower side and the lower side, and the sliding door cannot be opened or closed in a predetermined posture along a predetermined movement path, and if such a difference occurs, The twisting may make it difficult to open and close the sliding door smoothly, and in extreme cases, there is a risk that the hanging support mechanism of the sliding door or the guide mechanism at the bottom of the sliding door may be damaged.

In other words, the above-mentioned conventional engagement structure between the guide groove and the guide, even if the sliding door is pushed and pulled along the door surface direction,
This alone cannot generate the force that moves the sliding door in the direction perpendicular to the door surface, and it does not have a structure that restricts relative movement between the guide and the sliding door in the door surface direction. Even if the amount of movement of the sliding door in the direction perpendicular to the door surface is different between the top and bottom of the sliding door, the movement of the sliding door in the direction of the door surface is allowed, and therefore a large opening/closing force is concentrated on the top side of the sliding door. When activated, the upper part of the sliding door moves in the direction perpendicular to the door surface before the lower part of the sliding door, and at this time, the lower part of the sliding door is allowed to move in the direction of the door surface.
The sliding door will be tilted in a direction perpendicular to the door surface,
Furthermore, even though the amount of movement of the lower part of the sliding door in the vertical direction of the door surface is smaller than that of the upper part of the sliding door, it is moved in the direction of the door surface. The sliding door cannot follow the upper part of the sliding door when moving in this direction, and the sliding door tilts toward the door surface, making it impossible to open and close smoothly, and both the hanging support mechanism of the sliding door and the guide mechanism at the bottom of the sliding door are twisted and damaged. I was afraid. In addition, even if the opening/closing force is concentrated on the lower part of the sliding door in the direction of the door surface, the upper part of the sliding door is moved in the direction perpendicular to the door surface by the suspension support mechanism, but the guide groove at the lower part of the sliding door Since the engagement structure with the guide cannot generate a component of force to move the sliding door in the direction perpendicular to the door surface, it is difficult for the lower part of the sliding door to move in the direction perpendicular to the door surface, and the same possibility arose.

In view of the above-mentioned circumstances, the present invention has been developed to provide a guide mechanism that completely facilitates cleaning, prevents damage to objects or injuries, and allows the sliding door to be opened and closed smoothly. The purpose is to improve the mechanism and the guide mechanism at the bottom of the sliding door to prevent damage.

Next, embodiments of the present invention will be described with reference to illustrative drawings.

As shown in FIG. 1, the opening and closing opening of a storage box 1 such as a shoe cabinet is configured to be closed by a pair of left and right sliding doors 2 that can be moved laterally, and both sliding doors 2

are arranged in front and behind each other.

A pair of path switching members 8 are provided on the first member 3a so as to be swingable around a support shaft 9, so that the hanging member 4 is reliably moved in a predetermined direction. A linear or plate-shaped spring 10, whose center part is bent so as to protrude into the groove, is provided with both ends locked, to stably hold the sliding door 2 in the fully closed position, and to hold the sliding door 2 stably in the fully closed position and just before fully closed. The second member 3b is configured to be pressed into position, and is further configured to generate a collision sound between the second member 3b and the spring 10 as the second member 3b and the spring 10 are opened and closed.

A large diameter notch portion 6a for inserting and removing the hanging member 4 is provided at each of the ends of the notch 6 of the first and second support plate portions 5a and 5b, and a large diameter notch portion 6a of the hanging member 4 is provided. The stopper 11 that prevents movement from the first
and the second members 3a and 3b, so that the sliding door 2 can be easily attached and detached. Further, the stopper 11 is configured so that it can be stably held in the movement blocking position by fitting the convex portion 11a formed therein into a recess formed in the first or second support plate portions 3a, 3b. It has been done.

As shown in FIGS. 5 and 6, a guide mechanism 13 is provided at the bottom of the storage box 1, located at the left and right center of the opening and closing opening, as shown in FIGS. 5 and 6, to prevent the sliding door 2 from swinging back and forth. , the sliding door 2 is configured to smoothly move between a fully closed position and a position immediately before fully closed.

That is, a pair of left and right guides 16 are attached to the lid body 14 provided flush with the inner bottom surface of the storage box 1 so as to be able to swing freely around a support shaft 15 protruding from the bottom surface of the lid body 14. A portion 16a that engages with the formed guide groove 17 is made to protrude upward from a notch in the lid body 14, and the guide 16 is configured to swing as the sliding door 2 moves from a fully closed position to a position immediately before fully closed. In addition, the guide 16 is configured to be constantly engaged with the guide groove 17. In addition, a linear or plate-shaped spring 18 whose one end is locked to the lid 14,
The structure is configured so that the guide 16 is stably held at each of the swinging end positions by acting on the spring receiving portion 16b connected to the guide, thereby making it possible to securely fix the sliding door 2 in the fully closed position, and also 2
This prevents unexpected rocking of the guide 16 due to the closing operation. Further, the engaging portion 16a of the guide 16 is formed into an elongated shape such as a rectangle or an ellipse when viewed from above, and most of the guide groove 17 is formed to have a width L ₁ close to the width ₁ of the engaging portion 16a. The side 17a of the end of the guide groove 17 with which the guide 16 engages in the fully closed state is formed into a substantially circular shape with a diameter L ₂ close to the longitudinal dimension ₂ of the engaging portion 16a, so that the sliding door 2 is in the fully closed position. When it is in the engaging part 1
The guide 16 is swung so that the longitudinal direction of the engaging portion 16a intersects with the longitudinal direction of the guide groove 17, and the longitudinal direction of the engaging portion 16a is directed toward the longitudinal direction of the guide groove 17 when the sliding door 2 is in the position immediately before fully closed. The engaging portion 16a is configured to change direction as the sliding door 2 moves, so that when the sliding door 2 is opened, an external force for swinging is efficiently applied to the guide 16.

The sliding door device according to the present invention can be applied to various uses such as building doors and partitions, and the sliding door 2 may be configured to be flush with a fixed wall and overlap.

Further, the direction of movement of the sliding door 2 between the fully closed position and the immediately before fully closed position can be freely changed in design, and in short, it is sufficient if the sliding door 2 is configured to move in a direction perpendicular to the door surface.

Further, the specific structure of the guide 16 can be freely changed, and the suspension support structure of the sliding door 2 can also be modified in various ways.

In summary, the present invention provides an opening sliding door device in which the guide is oscillated around the vertical axis in a state in which the guide is always engaged with the guide groove and is disposed on one end side in the opening direction of the sliding door in the closed state. A portion of the guide that engages with the guide groove is formed in an elongated shape when viewed from above, and most of the guide groove is formed to have a width close to the width of the engagement portion. The end of the groove on which the guide engages in the fully closed state is formed into a substantially circular shape with a diameter close to the longitudinal dimension of the engaging portion, and the longitudinal direction of the engaging portion is formed so that the sliding door is As the guide swings, the direction intersects with the longitudinal direction of the guide groove when the sliding door is in the fully closed position, and toward the longitudinal direction of the guide groove when the sliding door is in the position immediately before fully closed. It is characterized by being configured to convert.

That is, the guide 16 is inserted into the guide groove 1 at the lower end of the sliding door 2.
7, in other words, by preventing the guide 16 from being exposed even in the fully open state, it is possible to make the bottom surface of the opening completely flat, making cleaning extremely easy, It has now become possible to completely eliminate the inconvenience of damage or injury to articles being taken in and taken out due to the guide 16.

The engagement groove structure between the guide groove 17 and the guide 16 allows the relative relationship between the sliding door 2 and the engagement portion 16a of the guide 16 to extend over the entire length of the movement path of the sliding door 2 from the fully closed position to the immediately before fully closed position. If the opening/closing force is applied to the sliding door 2 in the direction of the door surface without allowing movement,
This opening/closing operation force causes the engaging portion 1 of the guide 16 to
Since the structure is such that the reaction force acting on the guide 16 swings, the lower part of the sliding door 2 is always moved along a predetermined path as the engaging portion 16a of the guide 16 swings. The suspension support mechanism of the sliding door 2 and the guide mechanism 13 at the bottom of the sliding door 2 are not easily twisted and are not easily damaged.
