Description

The present invention relates to furniture with a door, and more particularly to furniture having a door that can open and close an opening provided on a side surface of a box body.

For box-shaped furniture such as lockers, cupboards, shoe racks, and cupboards that have doors on the sides, the doors are opened to store things inside the furniture through the openings. In such box-shaped furniture, since a rotary door is provided, a door stop or a door holder for positioning the closed state of the door and maintaining the position protrudes from the side surface or the top surface. It is common to have. Since such a door stop and a door holder protrude from the peripheral edge of the opening toward the space inside the furniture, the stored items do not collide with the door stop and the door holder when the stored items are taken in and out from the opening. It had to be done in the same way, which hindered the smooth loading and unloading operation.

Also, especially in the case of Buddhist altars and Kamidana with doors, when the door is fully opened, the Buddha sitting inside, the door stop and the door holder protrude from the side and top in front of the god. Therefore, there was a problem that not only the above-mentioned inconvenience of putting in and out but also lack of design.

Patent Document 1 discloses a door fixing mechanism as a substitute for a door stop used when a door (door) of a building is opened. Specifically, Patent Document 1 describes a door-side member having a magnet at the tip thereof, which is provided at the bottom of a building door so as to be able to move forward and backward with respect to the floor surface, and the door-side member at an open position of the door. Disclosed is a door fixing mechanism comprising a floor-side member capable of attracting the magnet, which is correspondingly arranged on the floor surface.

According to this door fixing mechanism, the magnet at the tip of the door-side member is normally urged by a spring in a direction away from the floor surface, but at the open position of the door, between the magnet and the floor-side member. The generated magnetic force pulls the door-side member out of the door against the urging force, and the magnet attracts the floor-side member, making it possible to fix the door in the open state.

As a result, the function of holding the position in the open state of the door is exhibited without providing the door stop used when the door is opened.

As shown in the above, the rotation of the doors 20-1 and 20-2 in the further opening direction (arrows 100c and 100d direction) is restricted at the open position.

Next, the magnetic material provided on the door 20-1 and the top plate 12 will be described. From this point onward, the magnetic material provided on the door 20-2 and the magnetic material provided on the top plate 12 corresponding to the magnetic material are arranged symmetrically with the magnetic material provided on the door 20-1 and the top plate. Therefore, the description thereof will be omitted.

As shown in FIG. 3, a substantially cylindrical recess 26-1 is provided at a position closer to the center side in the width direction of the upper end edge portion 20-1c of the door 20-1. On the bottom portion 26-1b of the recess 26-1, a substantially cylindrical first magnetic body 28-1 having a height slightly smaller than the height of the recess 26-1 is placed by its own weight.

The first magnetic body 28-1 is magnetically attracted to the second magnetic body 30-1 and the third magnetic body 32-1, which will be described later.

The first magnetic body 28, the second magnetic body 30, and the third magnetic body 32 are selected from permanent magnets and ferromagnets, respectively. Examples of the ferromagnet include iron, cobalt, nickel and alloys thereof (ferrite, etc.).

On the other hand, as shown in FIG. 3, the lower surface portion 12b (upper edge portion of the opening 24) of the top plate 12 is placed on the bottom portion 26-1b of the recess 26-1 of the door 20-1 in the closed position. The second magnetic body 30-1 is embedded at a position facing the first magnetic body 28-1, and the lower surface 30-1a of the second magnetic body 30-1 and the lower surface portion 12b of the top plate 12 are flush with each other. Is formed in.

Further, as shown in FIG. 3, the height h of the first magnetic body 28-1 is larger than the distance d between the lower surface portion 12b of the top plate 12 and the upper end edge portion 20-1c of the door 20-1. .. This is related to the first magnetic body 28-1 whose door 20-1 is adsorbed on the second magnetic body 30-1 when the first magnetic body 28-1 is adsorbed on the second magnetic body 30-1. This is to stop and regulate the behavior of the door 20-1 in the closed position.

Further, the lower surface portion 12b of the top plate 12 has a third position facing the first magnetic body 28-1 placed on the bottom portion 26-1b of the recess 26-1 of the door 20-1 in the open position. The magnetic body 32-1 is embedded, and the lower surface 32-1a of the third magnetic body 32-1 and the lower surface portion 12b of the top plate 12 are formed flush with each other.

Next, the movement of the furniture 10 when closing the door 20-1 will be described by exemplifying a case where the door 20-1 is moved from a position that is neither an open position nor a closed position to a closed position.

As shown in FIG. 4, the first magnetic body 28-1 is in the mounting position in the recess 26-1 in a state where the door 20-1 is neither in the open position nor in the closed position.

Next, the door 20-1 is rotated in the closing direction until the back surface portion 20-1b abuts on the front side end portion 14-1a of the side plate 14-1. As a result, the door 20-1 moves to the closed position, and as shown in FIG. 3, the first magnetic body 28-1 is attracted to the second magnetic body 30-1 at the opposite position.

If the door 20-1 is to be moved in the opening direction in this state, the inner peripheral wall 26-1a of the recess 26-1 comes into contact with the peripheral surface of the first magnetic body 28-1, and the door 20-1 in the opening direction Regulate movement.

Therefore, the door 20-1 is fixed in the closed position, and it is not necessary to provide a door stop or a door holder protruding from the opening 24 to the space inside the furniture 10 in order to fix the door 20-1 in the closed position. ..

Further, at the closed position of the door 20-1, the back surface portion 20-1b of the door 20-1 abuts on the front side end portion 14-1a of the side plate 14-1, and the door 20-1 is further rotated in the closing direction. When fixing the door 20-1 in the closed position, the door 20-1 is rotated until the back surface portion 20-1b of the door 20-1 abuts on the front side end portion 14-1a of the side plate 14-1. It suffices, and the closing operation is easy. At the same time, this configuration eliminates the need to provide a door stop that projects from the opening 24 into the space inside the furniture 10.

Next, the movement of the furniture 10 when the door 20-1 is opened will be described by taking as an example the case where the door 20-1 is moved from the closed position to the open position.

At this time, the peripheral surface of the first magnetic body 28-1 adsorbed on the second magnetic body 30-1 comes into contact with the inner peripheral wall 26-1a of the recess 26-1, and the door 20-1 moves in the opening direction. Although it is regulated, the door 20-1 by the first magnetic body 28-1 is applied by applying a force larger than the frictional force acting on the attraction surface between the second magnetic body 30-1 and the first magnetic body 28-1. The fixing of the door 20-1 is released, and the door 20-1 moves from the closed position to the opening direction.

After that, the door 20-1 is further rotated so that the front portion 20-1a of the door 20-1 faces and contacts the outer surface portion 14-1b of the side plate 14-1. As a result, the door 20-1 moves to the open position, and the first magnetic body 28-1 is attracted to the third magnetic body 32-1 at the opposite position.

If the door 20-1 is to be moved in the closing direction in this state, the inner peripheral wall 26-1a of the recess 26-1 comes into contact with the peripheral surface of the first magnetic body 28-1, and the door 20-1 in the closing direction Regulate movement.

Therefore, the door 20-1 is fixed in the open position, and it is not necessary to provide a door stop on the top plate 12 and the bottom plate 18 in the open position in order to fix the door 20-1 in the open position, and the door 20 is fixed. By omitting the arrangement of the door stop and the door holder in the open position of -1, the design of the furniture 10 can be further improved.

The first magnetic body 40-1 is fixed to the bottom portion 26-1b of the recess 26-1 by a nail 44 penetrating the through hole 42-1. At this time, in a state where the first magnetic body 40-1 does not face the second magnetic body 30-1 or the third magnetic body 32-1, as shown in FIG. 5A, the first magnetic body Reference numeral 40-1 is located on the bottom portion 26-1b of the recess 26-1 of the upper end edge portion 20-1c of the door 20-1.

On the other hand, as shown in FIG. 5B, in the closed position where the first magnetic body 40-1 faces the second magnetic body 30-1, the first magnetic body 40-1 is magnetically driven by the second magnetic body 30. It is permissible to move to the adsorption position where it is adsorbed by -1.

The first magnetic body 40-1 is further upwardly locked by the head 44a of the nail 44 at the suction position with the second magnetic body 30-1.

Here, the positional relationship between the first magnetic body 40-1 and the second magnetic body 30-1 at the closed position of the door 20-1 is the first magnetic body 40-1 and the first magnetic body 40-1 at the open position of the door 20-1. Since it also applies to the positional relationship with the 3 magnetic material 32-1, the description of the positional relationship between the 3rd magnetic material 32-1 and the 1st magnetic material 40-1 is omitted.

Therefore, according to the first magnetic body 40-1 according to the present modification, the first magnetic body 40-1 is fixed in the recess 26-1 of the door 20-1, so that when the furniture is transported, etc. Even if the door 20-1 is transported sideways or downward with the door 20-1 half-opened, there is no risk that the first magnetic body 40-1 will fall off from the recess 26-1, and it is safe.
