Description

  The present invention includes a top plate that extends in the front-rear direction, a leg portion that holds the top plate so that the top plate can rotate around a rotation axis in the left-right direction that intersects with the front-rear direction, and a front portion below the top plate. The present invention relates to a folding table comprising a curtain plate that can be pivoted around a pivot shaft that is disposed close to the curtain.

  When the table is stored, a folding table is used that can reduce the space for storing by rotating the top plate and standing along the legs that support the top plate. In such a table, if the curtain is provided, the curtain is arranged so that its main surface is vertical on the lower surface in front of the ceiling when the ceiling is substantially horizontal. . Then, when the top plate is rotated until the top plate is positioned along the leg, the curtain plate is also moved to a position along the leg portion via the link mechanism, and the top plate and the curtain plate become parallel and a part of them. Generally, it is configured to be in an overlapping storage state.

  However, in the folding table described above, as the top plate is rotated into the stowed state, the gap between the front end of the top plate and the front surface of the curtain plate becomes narrower, and it is necessary to perform operations when rotating the top plate. There is a risk of pinching. In this case, since the force is applied to the finger by the heel principle with the link portion at one end of the curtain plate as a fulcrum, the force received by the finger may become very large.

Therefore, conventionally, a folding table has been proposed in which a certain gap is provided between the curtain plate and the top plate, and the curtain plate is attached via a link mechanism so that the gap is maintained regardless of the rotation state of the top plate. Yes. With such a folding table, it is possible to reduce the risk of pinching a finger between the top and the curtain (see Patent Document 1).
JP 2004-121440 A

  However, in the technique disclosed in Patent Document 1, since there is always a gap between the top plate and the curtain plate, the curtain plate cannot be disposed between the top plate and the folding table because of the design. The limit occurred. Further, paragraphs [0030] and [0031] of Patent Document 1 describe that a cord can be wired in the gap, but when the gap is filled with the cord, the finger is pinched by the rotation of the top plate. The problem of getting injured will not be resolved. In addition, the number of parts for linking the top plate and the curtain plate increases, and in order to keep the curtain plate away from the top plate by a certain distance, it is necessary to enlarge the parts to be linked. There was a risk of pinching fingers.

  The present invention has been made in order to solve the above-described problems, and has an object to provide a folding table in which there are few restrictions on the arrangement of curtains and it is possible to suppress injury from being caught between fingers.

  The folding table according to claim 1, which has been made to solve the above-described problem, is such that the top plate can rotate around a top plate that extends in the front-rear direction and a left-right rotation axis that intersects the front-rear direction. The folding table includes a leg portion that holds the top plate and a curtain plate that is swingable about a swing shaft that is disposed closer to the front below the top plate.

The folding table includes a swing shaft holding portion that is attached to the top plate and holds the swing shaft, and the swing shaft holding portion has a first position and a first position along the top plate. The swing shaft is configured to be movable between the second position having a greater distance from the top plate than the top plate, and the swing shaft holding portion moves the swing shaft to the second position. And urging means for urging in the direction of the first position .

  If the top plate is rotated and the gap between the front end of the top plate and the curtain plate becomes narrow, there is a risk of fingers being caught in the gap, but with the folding table, the swing between the curtain plate and the top plate Because the shaft moves, even if you put your finger between the curtain and the top plate, strong force will not be applied by the principle of heel with the swing shaft as a fulcrum, so your finger will be pinched and injured Can be suppressed.

Further, in the case of the above folding table, there is no restriction on the design of the folding table because it is not necessary to arrange the swing shaft in advance with a certain gap from the top plate.
Thus, with the folding table according to the first aspect, it is possible to reduce the restriction on the arrangement of the curtains and to suppress the injury of the fingers.

Pivot shaft holding portion described above, that a shafts swinging have a biasing means for biasing the direction of the first position from the second position.
In the case of the folding table configured as described above, since the swinging shaft is normally at the first position close to the top plate, the function of the curtain plate due to an excessively large gap between the top plate and the swinging shaft. And no loss of design. Then, when a load is applied to the swing shaft, such as when a finger is pinched, it moves to the second position, so that the risk of injury due to the finger being pinched can be reduced.

Further, the folding table described above includes a second rotating shaft, a second rotating shaft, and a swing shaft provided on the top plate in a positional relationship in which the swing shaft holding portion is parallel to the swing shaft. And a connecting member connected to each of them, and the connecting member rotates about the second rotating shaft so that the swing shaft can move between the first position and the second position. Further, the biasing means may be configured to bias the connecting member so that the swing shaft moves from the second position to the first position.
In the folding table described above, the top plate can transition between a use state in which the top plate is horizontal and a storage state in which the top plate is in a standing state. The oscillating shaft may be biased in the direction from the second position to the first position.
Further, as described in claim 4 , the folding table described above may be configured to include a link member that is rotatably attached to the curtain plate and the leg portion and moves the curtain plate as the top plate rotates. .

  If it is a folding table comprised in this way, a curtain plate can be moved by rotating a top plate. If the link member is configured such that the main surface of the curtain plate is substantially vertical when the top plate is substantially horizontal, it is convenient because the curtain plate moves to an appropriate position when the folding table is in use.

Further, the coil spring 55 contacts the curtain plate bracket 54A and the curtain plate mounting bracket 57, and biases the curtain plate bracket 54A in the A direction in FIG. This A direction is the clockwise biasing direction in FIG.

The urging force of the coil spring 55 is set to such a force that the curtain plate 30 is lifted upward and the curtain plate bracket 54 comes into contact with the top plate 10.
(2) Operation of Folding Table First, the folding operation of the folding table 1 will be described.

FIG. 1 mentioned above is a figure which shows the use condition in which the main surface of the top plate 10 is horizontal. In this use state, the main surface of the curtain plate 30 is vertical.
FIG. 4 shows an enlarged view of the swing shaft holding portion 50 in the use state. The curtain plate bracket 54 is urged by a coil spring 55 in the clockwise direction around the curtain plate bracket shaft 53. Therefore, the end of the curtain plate bracket 54 on the side holding the swing shaft 32 is rotated to a position where it contacts the top plate 10. At this time, the position of the swing shaft 32 with respect to the top plate 10 is the first position in the present invention.

  When the rear side of the top plate 10 (the right side in FIG. 1) is raised or the front side of the top plate 10 is lowered, the top plate 10 rotates around the rotary shaft 11 as shown in FIG. It becomes a state.

  When the top plate 10 is further rotated in the same direction as described above, the top plate 10 is in a stowed state in which it stands up along the main leg 21 of the leg portion 20 as shown in FIG. In this state, the curtain plate 30 is moved to a position along the main leg 21 by the link member 33 as the top plate 10 rotates.

  FIG. 7 shows an enlarged view of the swing shaft holding portion 50 in the stored state. The curtain bracket 54 is urged clockwise by the coil spring 55 as in the use state. The urging force at this time is a force directed in the direction B in FIG.

Next, the swing axis moving operation of the swing axis holding part 50 will be described.
FIG. 8 shows a position where the swing shaft 32 is separated from the top plate 10 by applying a force in the C direction to the curtain plate 30 and applying a force in the direction opposite to the B direction to the curtain plate bracket 54 in the retracted state. It is a figure which shows the rocking | fluctuation shaft movement state which moved to (3).

  FIG. 9 shows an enlarged view of the swing shaft holding portion 50 in the above-described swing shaft movement state. When urging in the C direction with a force stronger than the urging force of the coil spring 55 applied to the curtain plate 30, the curtain plate bracket 54 rotates counterclockwise about the curtain plate bracket shaft 53 as a rotation axis, and the swing shaft 32 is moved to the top plate 10. Is moved from a position along the top to a position farther from the top plate 10 than the above position. The position of the swing shaft 32 relative to the top plate 10 at this time is the second position in the present invention.

When the urging in the C direction is released, the curtain bracket 54 rotates again in the clockwise direction, the swing shaft 32 returns to the first position, and the storage state shown in FIG. 7 is restored.
(3) Effects of the Invention The folding table 1 described above has the swing shaft 32 moved from the first position to the second position when the curtain plate 30 moves in the direction opposite to the direction of the urging force received by the coil spring 55. Move to. Therefore, when the top plate 10 is rotated by grabbing the front of the top plate 10 and the finger is sandwiched between the top plate 10 and the curtain plate 30, the finger is pushed by the finger and the curtain plate 30 is removed from the top plate 10. It moves to the direction which leaves | separates, and the rocking | fluctuation shaft 32 will move according to it.

  Therefore, in the folding table 1 described above, the swinging shaft 32 moves even if the finger is sandwiched between the top plate 10 and the curtain plate 30, so that the swinging shaft 32 serves as a fulcrum and the finger is moved with a strong force. Can be prevented from being injured. Further, since the urging force of the coil spring 55 is set so as to lift the curtain plate 30 to the top plate 10 in the usage state, the finger is not injured by the urging force of the coil spring 55.

  Note that the movement of the swing shaft 32 described above is realized not only when the folding table 1 is in the stored state, but also when the folding table 1 is in the used state and in the rotating state, so that the folding table 1 is in any state. The finger can be prevented from being injured by being sandwiched between the top plate 10 and the curtain plate 30.

When the curtain plate 30 is not pressed by a finger or the like, the swing shaft 32 is positioned at the first position along the top plate 10 by the biasing force of the coil spring 55. Therefore, it is possible to prevent the curtain plate 30 from being separated from the top plate 10 in the use state, so that a large gap is generated between the top plate 10 and the curtain plate 30 and the function of the curtain plate 30 cannot be exhibited. Moreover, it can prevent that the design property of the folding table 1 is impaired.
(4) Modifications The embodiment of the present invention has been described above. However, the present invention is not limited to the above embodiment, and can take various forms as long as they belong to the technical scope of the present invention. Needless to say.

  For example, in the above embodiment, the configuration in which the swing shaft 32 moves as the curtain plate bracket 54 rotates about the curtain plate bracket shaft 53 is illustrated. However, if the swing shaft 32 can move, the swing shaft 32 moves. The specific configuration of the moving shaft holding unit 50 is not particularly limited. For example, as shown in FIG. 10, a configuration in which a rail 60 that holds the swing shaft 32 movably in the vertical direction is formed on the lower surface of the top plate 10 can be considered. In that case, you may comprise so that the rocking | swiveling axis | shaft 32 may be urged | biased by the urging means, such as the spring 61, to the top plate 10 side.

  Further, in the above-described embodiment, the configuration in which the swing shaft 32 is located at the first position along the top plate 10 at the normal time when the curtain plate 30 is not pressed with a finger or the like is illustrated, but as shown in FIG. A configuration may be adopted in which the swing shaft 32 is urged by the coil spring 55 and is arranged at a position where the top plate 10 and the constant gap 70 are provided.

  The folding table constructed as described above can be used by passing a cord through the gap 70 and wiring it. Even if the top plate 10 is rotated in this state, the top plate 10 and the curtain plate 30 are used. There is no risk of pinching the cord. Furthermore, even if the top plate 10 is rotated and the finger is pinched at the same time as the cord or the like, the swinging shaft 32 moves in a direction away from the top plate 10, so that the finger can be prevented from being injured.
