Description

  The present invention relates to a table mainly used in an office, a school or the like.

2. Description of the Related Art Conventionally, there is known a table that can perform a flap operation in which a top plate is set in a horizontal posture when in use and a top plate is flipped up and raised in a non-use state. In such a table, a curtain plate that hides the lower limb space is often suspended from the top plate. Further, a table devised so that cords (power supply cord, communication cable, etc.) can be inserted between the top plate and the curtain plate has been devised. The table disclosed in Non-Patent Document 1 below is provided with a drive mechanism for moving the curtain plate up and down, and can open and close the gap between the top plate and the curtain plate through the vertical movement of the curtain plate. ing. If it is such, the wiring operation | work which drops the cords connected to the various apparatuses mounted on a top plate under a top plate becomes easy.

  However, in the table described in Non-Patent Document 1, a heavy curtain must be moved up and down during wiring work, which imposes a considerable burden on the user. Also, when the user goes into the lower limb space and performs wiring work, it is difficult to lift the curtain with an unnatural posture. In addition, the complexity of the table structure and the increase in the number of parts associated with the mounting of the curtain driving mechanism are unavoidable, leading to an increase in manufacturing cost. In addition, since the operation buttons of the drive mechanism are arranged at predetermined positions (specifically, the left and right sides of the table), there is also a complication that the curtain plate cannot be driven unless it reaches that position.

  An object of the present invention made in view of the above problems is to enable easy opening and closing of a gap serving as a wiring insertion port.

  In order to solve the above-described problems, in the present invention, a top plate capable of performing a flap operation, wiring holding means capable of holding cords guided to a lower limb space under the top plate, and a flap operation of the top plate are interlocked. A curtain plate that is supported by the top plate via a suspension member so as to be displaced and disposed below the top plate in a state where the top plate is in a horizontal posture, and is generated between the top plate and the curtain plate. A shielding member for shielding the gap, and a shielding position provided on the suspension member or the curtain plate, wherein the shielding member substantially shields the gap, and an open position for opening at least a part of the gap. Thus, the table comprising the supporting means for movably supporting the shielding member was configured.

  With such a configuration, it is possible to open and close the gap by operating only the shielding member, and it is not necessary to move the entire curtain plate up and down. The shielding member can be made lighter than the curtain, so that the burden on the user can be reduced. Moreover, as long as the hand reaches the shielding member, the gap can be easily opened and closed from any position, and the convenience of wiring work is improved. Furthermore, it is freed from the need to mount a drive mechanism that moves the curtain up and down, leading to a reduction in manufacturing costs. In addition, since the curtain plate and the shielding member operate integrally when the top plate is operated to flap, it is possible to avoid the presence of the shielding member from hindering the interlocking of the top plate and the curtain plate. Moreover, the structure of the table is not complicated.

  If the upper end side of the shielding member is separated from the top plate and the gap is opened as the shielding member is displaced from the shielding position to the open position, the cords are arranged from above the top plate to below the top plate. It is suitable for dropping.

  If a hinge that supports the shielding member so as to be rotatable about a horizontal axis is provided as the supporting means, it becomes easy to use because the gap is opened by tilting the shielding member.

  The suspension member is provided with a projecting portion projecting to the opposite end, and the curtain plate is joined to the projecting portion so that the suspension member and the curtain plate are separated from each other by a predetermined distance. If the shielding member is arranged between the plate and the plate, the shielding member can be arranged on the use end side with respect to the curtain plate, and at the same time, the lower end portion of the shielding member and the upper end portion of the curtain plate can be overlapped in the rear view. Thus, the furniture can be maintained without creating a gap between the rear view shielding member and the curtain.

  Even when the shielding member is in the shielding position, there may be a slight gap between the shielding member and the top plate (particularly when cords are inserted between the shielding member and the top plate). However, if a hanging wall that hangs downward from the downward surface of the top plate and faces away from the use end is provided at a position closer to the use end than the shielding member, light passing through the gap is blocked by the drop wall. be able to. And the concealment of the lower limb space under the top plate becomes more reliable. Since it is not necessary to strictly eliminate the gap between the shielding member and the top plate, the degree of freedom in design increases.

  In addition, if a horizontal wall extending from the hanging wall to the side opposite to the end of use is provided, the hanging wall and the horizontal wall form a wiring duct that communicates with the gap. Wiring on a horizontal wall becomes possible. That is, the hanging wall and the horizontal wall constitute the wiring holding means.

  In addition, if an urging means for urging the shielding member toward the shielding position is provided, the shielding member can be easily returned to the shielding position, and the state in which the shielding member shields the gap is appropriate. Can be maintained.

  According to the present invention, since it is possible to open and close the gap by operating only the shielding member, it is possible to reduce the burden on the user in wiring work. Further, as long as the hand reaches the shielding member, the gap can be easily opened and closed from any position, and the convenience of wiring work is improved. Furthermore, it is freed from the need to mount a drive mechanism for moving the curtain up and down on the table, leading to a reduction in manufacturing costs.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the description, the use end side on which the user who uses the table is seated is defined as the front, and the counter-use end side on which the curtain plate 3 stands up is defined as the rear.

  The table of the present embodiment is a so-called flap table capable of performing a flap operation of the top board 2 and is used as a conference table, for example. As shown in FIG. 1 to FIG. 8, this table mainly includes left and right legs 1, a top board 2 supported by the legs 1, and a curtain board 3 that conceals the lower limb space under the top board 2. This is a component.

  The leg 1 includes a base 11 and leg struts 12 extending forward and upward from the rear end portion of the base 11. A caster 13 is attached to the base 11. In addition, a braking mechanism (not shown) is mounted on the base 11, and when the lock button 14 exposed on the base 11 is operated, the braking mechanism brakes the caster 13 to inhibit the table movement. The leg support 12 is mainly composed of a hollow rectangular pipe material, and supports the top plate 2 at the upper end portion thereof.

  The top plate 2 includes a top plate main body 21 and a movable bracket 22 fixed to the lower surface of the top plate main body 21. The top plate body 21 is a flat plate having a substantially rectangular shape. The movable bracket 22 is a member formed by bending a thick sheet metal material into a U-shape that opens downward, and supports the left and right sides of the top plate body 21 from below. The movable bracket 22 has a support shaft 15 extending between upper ends of the leg struts 12 on both sides. That is, the top plate 2 is supported by the leg columns 12 so as to be rotatable around the support shaft 15. Further, a top plate 2 locking mechanism (not shown) is interposed between the leg column 12 and the movable bracket 22, and when the operation lever 23 attached to the movable bracket 22 is operated, the lock by the top plate 2 locking mechanism is released. The top plate 2 is allowed to rotate. Incidentally, a plurality of substantially cylindrical horizontal members 24 are arranged side by side in the front-rear direction and joined to the opposing inner side surfaces of both movable brackets 22 to construct a shelf on which articles can be placed. In addition, a wiring duct 25 serving as a wiring holding means is provided at a position behind the shelf. As shown in FIG. 7, the wiring duct 25 hangs down from the lower surface of the top plate body 21 and faces in the front-rear direction, and bends or curves from the lower end of the suspending wall 251 to be the rear end of the movable bracket 22. The horizontal wall 252 extending to the vicinity forms an angle shape that opens rearward. A through hole 253 is formed in a predetermined portion of the horizontal wall 252, and cords wired on the horizontal wall 252 can be lowered onto the floor from the through hole 253.

  The curtain plate 3 is arranged below the top plate 2 to conceal the lower limb space. The curtain plate 3 in the present embodiment is a plate-like body having a substantially rectangular outer shape in which a plurality of concave strips are formed by extruding a synthetic resin and extending in the width direction. The curtain plate 3 is supported by the top plate 2 via a suspension member 31. Specifically, the lower end side of the suspension member 31 is fixed to the upper end portion of the curtain plate 3, while the upper end of the suspension member 31 is attached to the lower surface of the rear end portion of the top plate body 21 via the hinge 32. Thus, the curtain plate 3 is suspended from the top plate body 21. Since the hinge 32 is interposed between the suspension member 31 and the top plate 2, the curtain plate 3 can be rotated relative to the top plate 2. Further, a projecting portion 33 projecting rearward is provided at the lower end portion of the suspension member 31, and the rear surface of the projecting portion 33 is joined to the front surface of the upper end portion of the curtain plate 3. 3 is separated in the front-rear direction by the thickness of the protrusion 33. Note that the suspension member 31 is attached to a plurality of locations in the width direction (in the illustrated example, three locations on the center and on both the left and right sides). Further, the lower end portion of the curtain plate 3 is connected to a portion in the vicinity of the lower edge of the leg column 12 via a link member 34. The link member 34 is attached to each of the curtain plate 3 and the leg column 12 via pins 35 and 36 at both ends thereof, and is rotatable relative to both.

  When the table is not used, the front end side of the top plate 2 can be flipped up to be in a state suitable for storage. That is, after operating the operation lever 23 to release the lock by the top plate 2 locking mechanism, the top plate 2 can be rotated vertically to be in a standing posture as shown in FIG. At this time, the rear end side of the top plate 2 is lowered, and at the same time, the curtain plate 3 is inclined at substantially the same angle as the top plate 2.

  Needless to say, when the table is used, the top plate 2 may be reversely rotated so that the front end side is pulled down to a horizontal posture as shown in FIG. When the top plate 2 is in a horizontal posture, the curtain plate 3 is substantially upright in conjunction with the rise of the rear end side of the top plate 2. Further, as shown in FIG. 7 and the like, the lower surface of the top plate body 21 and the upper end surface of the curtain plate 3 are separated by a predetermined distance to form a gap S, and cords can be inserted into the gap S. ing. Since the wiring duct 25 provided on the top plate 2 communicates with the gap S, cords connected to various devices placed on the top plate 2 can be suitably guided to the wiring duct 25 via the gap S. .

  In the table having the basic configuration as described above, in the present embodiment, a shielding member 4 for shielding the gap S generated between the top plate 2 and the curtain plate 3 is provided. The shielding member 4 is a thin plate that is long in the width direction, and its width dimension is substantially equal to the width dimension of the curtain plate 3. In consideration of design, the shielding member 4 is formed in a curved shape so as to be slightly recessed forward. In addition, the shielding member 4 is darker than the curtain plate 3 and other members. These are ideas for making the presence of the shielding member 4 inconspicuous when the table is viewed from the rear. This shielding member 4 is movably supported via a support means. More specifically, the shielding member 4 is attached to the suspension member 31 via a hinge 41 serving as a support means, thereby supporting the shield member 4 so as to be rotatable about a horizontal axis. The hinge 41 is attached to a lower part of the shielding member 4 and can swing the upper end side of the shielding member 4 in the front-rear direction. The shielding member 4 is disposed between the suspension member 31 and the curtain plate 3 that are separated in the front-rear direction in a side view. The vicinity of the lower end of the shielding member 4 and the vicinity of the upper end of the curtain plate 3 overlap with each other in the rear view, so that a gap is not visually recognized between the shielding member 4 and the curtain plate 3. Incidentally, when the top plate 2 is in an upright posture, the rear end portion of the top plate 2 covers the upper end portion of the curtain plate 3 from behind, but the shielding member 4 exists in front of the curtain plate 3. The flap operation of the top plate 2 is not hindered. The fact that the shielding member 4 is in front of the curtain plate 3 is also effective for making the shielding member 4 inconspicuous. Further, since the lower end portion of the shielding member 4 is exposed to the lower limb space below the top plate 2 as shown in FIG. 5, the shielding member 4 can be easily used even when the user enters the lower limb space and performs wiring work. Can be operated.

  When the shielding member 4 is erected so as to be substantially parallel to the curtain plate 3, the gap S between the top plate 2 and the curtain plate 3 is substantially concealed when viewed from the back, as shown in FIG. At the shielding position D, the upper end of the shielding member 4 is slightly separated from the lower surface of the top plate body 21. Therefore, there is no possibility that the cords inserted through the gap S will interfere with the shielding member 4, and it is not necessary to form a notch or the like (for passing the cords) in the shielding member 4. Furthermore, this means that the shielding member 4 does not completely hide the gap S. However, since the upper part of the gap S that is not hidden by the shielding member 4 is shielded by the hanging wall 251 of the wiring duct 25, the gap It is not possible to see the front and back of the table through S, and the table furniture is maintained.

  If the upper end side of the shielding member 4 is rotated so as to be pulled out rearward and downward, the shielding member 4 can be positioned at the open position O. At this time, as shown in FIGS. 6 and 8, the gap S between the top plate 2 and the curtain plate 3 is opened in a rear view, and the cords can be easily inserted into the gap S. It is desirable to provide an urging means for urging the shielding member 4 toward the shielding position D. For example, a spring (in particular, a torsion spring 42 integrally assembled with the hinge 41) that exhibits a reaction force against the backward tilting of the shielding member 4 is attached to serve as the biasing means. In addition to the spring 42, a magnet may be employed as the biasing means. When the suspension member 31 (or the shielding member 4) is made of a ferromagnetic metal, a magnet is attached to the shielding member 4 (the suspension member 31), and when the shielding member 4 is positioned at the shielding position D, the magnet If it is configured to contact the suspension member 31 (the shielding member 4), the shielding member 4 can be biased toward the shielding position D.

  According to the present embodiment, in the table including the top plate 2 capable of performing the flap operation and the curtain plate 3 disposed below the top plate 2 in a state where the top plate 2 is in a horizontal posture, the top plate 2 And a shielding member 4 for shielding the gap S generated between the curtain plate 3 and the shielding position D where the shielding member 4 substantially shields the gap S, and an open position where at least a part of the gap S is opened. Since the supporting means for movably supporting the shielding member 4 is provided so as to be able to take O, it becomes possible to open and close the gap S by operating only the shielding member 4, without moving the entire curtain plate 3 up and down. Get better. The shielding member 4 can be made lighter than the curtain plate 3, so that the burden on the user can be reduced. Further, as long as the hand reaches the shielding member 4, the gap S can be easily opened and closed from any position, and the convenience of wiring work is improved. Furthermore, it is freed from the need to mount a drive mechanism that moves the curtain plate 3 up and down, leading to a reduction in manufacturing costs.

  As the shielding member 4 is displaced from the shielding position D to the open position O, the upper end side of the shielding member 4 is separated from the top plate 2 so that the gap S is opened. This is suitable for dropping cords under the plate 2.

  Since the hinge 41 that supports the shielding member 4 so as to be rotatable about a horizontal axis is provided as the support means, the clearance S is opened by tilting the shielding member 4, which is easy to use.

  The curtain plate 3 is supported by the top plate 2 via a suspension member 31, and is displaced in conjunction with the flap operation of the top plate 2. The shielding member 4 is attached to the support means. Therefore, the curtain plate 3 and the shielding member 4 operate integrally when the top plate 2 is operated to flap. Therefore, it can be avoided that the presence of the shielding member 4 hinders the interlocking of the top plate 2 and the curtain plate 3. Moreover, the structure of the table is not complicated.

  The suspension member 31 is provided with a projecting portion 33 projecting to the opposite end side, and the curtain plate 3 is joined to the projecting portion 33 so that the suspension member 31 and the curtain plate 3 are separated by a predetermined distance. Since the shielding member 4 is disposed between the suspension member 31 and the curtain plate 3, the shielding member 4 can be disposed closer to the use end than the curtain plate 3, and at the same time, the lower end portion of the shielding member 4 and the upper end of the curtain plate 3. Can be overlapped with each other in the rear view. Thereby, the form as furniture can be maintained, without creating a space | gap between the back view shielding member 4 and the curtain board 3. FIG.

  Since a hanging wall 251 that hangs downward from the downward surface of the top plate 2 and faces away from the use end is provided at a position closer to the use end than the shielding member 4, the upper end of the shielding member 4 and the top plate main body 21 are provided. The light that passes between the lower surface and the lower wall can be blocked by the hanging wall 251, so that the lower limb space under the top plate 2 can be concealed more reliably. Since it is not necessary to eliminate the gap between the shielding member 4 and the top plate 2 strictly, the degree of freedom in design is also increased.

  In addition, since the horizontal wall 252 extending from the hanging wall 251 to the opposite end side is provided, the hanging wall 251 and the horizontal wall 252 form a wiring duct 25 communicating with the gap S. The guided cords can be wired on the horizontal wall 252.

  In addition, since the biasing means (spring 42) for biasing the shielding member 4 toward the shielding position D is provided, the shielding member 4 can be easily returned to the shielding position D. A table can be realized, and the state in which the shielding member 4 shields the gap S can be appropriately maintained.

  The present invention is not limited to the embodiment described in detail above. For example, the shielding member 4 can be supported not on the suspension member 31 but on the curtain plate 3. Further, the rotation axis of the hinge 41 that supports the shielding member 4 and the rotation axis of the hinge 32 provided at the upper end of the suspension member 31 can be arranged on the coaxial line in side view. In this case, the rotation axis of the hinge 41 and the rotation axis of the hinge 32 can be the same member.

  A hinge 41 that supports the shielding member 4 may be attached to an upper portion of the shielding member 4 so that the lower end side of the shielding member 4 can be swung.

  As a support means for supporting the shielding member 4, it is not obstructed to employ a mechanism other than the hinge 41.

  The shielding member 4 may be provided with an operation unit (such as a knob) that is gripped when the shielding member 4 is opened and closed.

  The wiring holding means is not limited to the wiring duct 25, and may be a hook that can hang cords. Further, the wiring holding means may be provided not on the lower surface of the top plate body 21 but on the front surface of the curtain plate 3.

  Other specific configurations of the respective parts are not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.
