  The present invention relates to a table device, and more particularly to a table device that includes a top plate and a top plate supporting portion that supports the top plate, and is configured to be capable of tilting the top plate.

  2. Description of the Related Art Conventionally, as a table device used in combination with a bed or a chair, there is known a table device in which a top plate can be used with an inclination.

Here, a conventional table device will be described with an example.
18 is an explanatory view showing a configuration of an example of a conventional table device, FIG. 19 is an explanatory diagram showing a state in which a top plate of the table device is inclined, and FIG. 20 is a diagram showing a state in which the top plate of the conventional table device is inclined. FIG. 21 is an explanatory diagram of another example, FIG. 21 is an explanatory diagram showing the configuration of another example of the conventional table device, and FIG. 22 is an explanatory diagram showing a tilted state of a top plate of the table device in a side view.

  As an example of a conventional table device, as shown in FIG. 18, in a table device 101 provided with a table plate (top plate) 110, a table plate support 120, a support 130, and legs 140, as shown in FIG. There is known a table device configured to be able to tilt the table plate 110 in a specific direction according to a use situation.

  As shown in FIG. 20, the table plate 210 is rotatably provided on one table plate support portion 220 provided horizontally with respect to the support portion 230, and the table is mounted around the table plate support portion 220. There is known a table device 201 that can be easily inclined by rotating a plate 210.

  However, in such a configuration, when the table plate 210 is not securely fixed to the table plate support portion 220, there is a problem that the table plate 210 is easily rotated when an object is placed on the table plate 210. Occurs.

  As another example, as shown in FIGS. 21 and 22, in a table device 301 including a table plate 310, a table plate support 320, a column 330, and a leg 340, a table plate supporting the table plate 310 is provided. A lock mechanism (not shown) for locking rotation to the support portion 320 is provided, and only when the lever 321 provided on the table plate support portion 320 is operated, the lock mechanism is released to incline the table plate 310. There is known a table device 301 which can be used.

  However, in order to construct an off-lock type structure in which the lock mechanism is released only when the lever is operated, a dedicated component is required, and the configuration is complicated, so that it is difficult to realize a general-purpose component. Occurs.

  Therefore, as a conventional technique, for example, a horizontal holding member arranged in a horizontal direction with respect to a vertical support and a table plate held in a horizontal direction by the horizontal holding member are rotated around the horizontal holding member. There has been disclosed a table device that is inclined at (see Patent Document 1).

  With this configuration, the table plate is held at a plurality of locations separated in the width direction by the holding member, so that the inclined table plate can be stably held with a simple configuration.

At least two columnar members are disposed at intervals substantially in parallel along the longitudinal direction of the plate, and as a configuration of the top plate, the top plate is rotated by one of the two columnar members. A pivoting support member (bearing portion) that supports the pivoting member, and is connected to the other of the two columnar members to limit the displacement caused by the pivoting of the top plate and maintain the inclined state of the top plate. An inclination holding member (stay), wherein the rotation support member is configured to be attachable to any of the two columnar members, and the inclination holding member is attached to any of the two columnar members. The top plate is configured to be connectable, and one of the top plates along the longitudinal direction of the top plate with respect to the top plate support portion. Or, it is configured to be attachable in the opposite direction, and the direction in which the top plate is inclined when the top plate is attached to the top support portion in one direction along the longitudinal direction of the top plate. When the top plate is attached to the top plate supporting portion in a direction opposite to one direction along the longitudinal direction of the top plate, the direction in which the top plate is inclined is the opposite direction. It is characterized by the following configuration.

  Further, the present invention includes, as a configuration of the top plate supporting portion, a columnar member supporting portion to which the two columnar members are attached, wherein one end of the two columnar members is attached to the columnar member supporting portion. Preferably, the other end side is open, and the top plate is attached along the longitudinal direction of the top plate from the other end side of the columnar member.

  Further, the present invention preferably includes a regulating member (resin seat, stopper portion) for regulating the movement of the rotation supporting member to the open end of the columnar member.

  Further, in the present invention, it is preferable that the regulating member functions as a buffer member that comes into contact with the top plate.

  In the present invention, it is preferable that a beam member is provided between the two columnar members.

  In the present invention, it is preferable that the beam member functions as a positioning member for setting a mounting position of the rotation support member to the columnar member.

  Further, according to the present invention, one end of the tilt holding member is attached to a substantially central portion in the longitudinal direction of the top plate, and the other end is attached to the columnar member by a fastening member (for example, a fastening member with a knurl). Is preferred.

  Further, according to the present invention, the top plate is formed in a substantially symmetrical shape around a center portion in the longitudinal direction, and the rotation support member is disposed at a position substantially symmetrical about the center portion in the longitudinal direction of the top plate. Is preferably performed.

According to the table device of the present invention, there is provided a table device including a top plate and a top plate support portion (top plate support) for supporting the top plate, wherein the top plate support portion has the configuration of the top plate At least two columnar members arranged at substantially lower intervals along the longitudinal direction of the top plate at a lower part of the top plate, and as a configuration of the top plate, one of the two columnar members is A rotation support member (bearing portion) that rotatably supports the top plate, and is coupled to the other of the two columnar members to limit displacement due to rotation of the top plate to allow the top plate to rotate; A tilt holding member (e.g., an extendable variable stay or the like) that holds a tilt state, wherein the rotation support member is configured to be attachable to any of the two columnar members, A member is configured to be connectable to any of the two columnar members, and the top plate is The top plate can be attached to the support in one direction or the opposite direction along the longitudinal direction of the top plate. When mounted in the direction of the direction, the top plate is mounted in the direction in which the top plate is inclined and in the direction opposite to the one direction along the longitudinal direction of the top plate with respect to the top plate support portion. Sometimes, by configuring the table to be opposite to the direction in which the table is inclined, depending on the installation state of the table device, to which columnar member the rotation support member of the table is mounted. Thus, the inclination direction of the top plate can be easily set, and the top plate can be inclined in any direction by easy recombination. Further, since the inclined holding member is supported by the other columnar member, the top plate can be always supported by the two columnar members, so that even if a trouble occurs in the inclined holding member, it is supported by the columnar member. In addition, the top plate can be safely supported without tilting or rotating below the horizontal.
