  By the way, when this type of flap table is used by a plurality of people, the use edge on the side where the user sits is determined among the edges in the depth direction, and the wiring outlet can be reached by the user. Since it is set to the range, there is no problem in use.

  However, when a large-sized flap table that can be used by multiple people in a face-to-face manner is formed, if a wiring outlet exists at such a position on the top plate surface, the use of the top plate surface is difficult for one user. This obstructs the use of the wiring outlet for the other user and makes the processing of wiring and concentrating uneven. In the document, the front panel also serves as a curtain plate. However, when realizing the face-to-face use state, it is necessary to reconsider the position of the curtain plate in relation to the flap operation.

  An object of the present invention is to provide a flap table that can cope with the above-described problems and appropriately perform wiring processing even when the top plate is large.

  In order to achieve this object, the present invention takes the following measures.

That is, the flap table of the present invention, to the top plate to perform the flap operation, the takeout wires on the surface of the central portion of the top plate depth direction perpendicular to the axis which is the center of the flap operation provided, the wiring outlet When part or all of the use area in the depth direction of the top plate is divided across the top plate, through the brackets arranged so that both edges in the width direction across the wiring outlet of the top plate span the both regions. It is characterized by being supported by a leg .

  In this way, by providing the wiring outlet in the center of the top plate in the depth direction, it is possible to access all parts of the top plate evenly, and the concentrating process becomes easy. It is possible to effectively construct an environment in which electronic devices can be easily used.

In addition, since both edges in the width direction are supported by the legs through the brackets arranged so as to straddle both regions across the wiring outlet of the top plate, the wiring outlet is at the center of the top plate. By providing it, the strength of the top plate can be effectively ensured when part or all of the use area in the depth direction of the top plate is divided across the wiring outlet.

  In particular, in order for the top plate to perform a flap operation and maintain a good wiring state, it is desirable that the axis serving as the center of the flap operation is also set near the center of the top plate in the depth direction. Here, the “near” in the central portion is a range where the above-described action can be obtained, and in addition to the case where the axis line matches the center of the top plate in the depth direction, for example, from the center of the top plate in the depth direction. Fixed brackets attached to the legs raised from the center in the depth direction are provided on both sides of the top plate, with a displacement amount of 2 to 3 times the thickness of the top plate or in a range where the axis does not come off the wiring outlet It can be based on various criteria such as the range that can be accommodated in the movable bracket.

  In this case, in order to avoid the wiring entering and exiting the wiring outlet from interfering with the rotating shaft or the like, the center position in the depth direction of the top plate is in the depth direction of the top plate with respect to the position of the axis that is the center of the flap operation. It is preferable to be offset.

  In order to properly arrange the curtain plate in consideration of providing the wiring outlet in the center of the ceiling plate, the curtain plate is similarly provided at a position below the central portion in the depth direction of the ceiling plate, and the top plate is operated during the flap operation. It is preferable that the frame stands up in parallel with the side of the curtain.

  In order to appropriately maintain the wiring during the flap operation of the top plate, it is desirable to form a wiring space in which at least two sides in the depth direction of the top plate are closed in the wiring outlet.

  In forming such a wiring space, when the edge in the width direction of the top plate is supported by the leg body via the bracket and the brackets are connected by the top plate receiving member, the top plate receiving member It is effective to form a wiring duct for closing the wiring space using

  The left and right brackets have locking pieces that can be operated between a locked position and an unlocked position, and are connected by an interlocking shaft extending in parallel along the top plate receiving member. When the top plate is configured to be selectively locked to either the use position or the standing position in association with the section, the wiring duct is arranged over a range that shields the interlocking shaft from the wiring outlet. It is convenient to keep it.

  In order to effectively present the configuration of bringing the wiring function to the center of the flap table, the cover can be maintained at a position for opening and closing the wiring outlet on the top plate surface, and the closed state can be maintained during the flap operation via the holding means. It is preferable to arrange in a state.

  In this case, in order to keep the ease of use of the top plate surface when the cover is closed, an open part that opens a part of the wiring space is provided on the side of the cover at the closed position to enable the drawing of the wiring. It is desirable.

  Since the present invention has the configuration described above, the wiring outlet provided on the top plate that performs the flap operation can be appropriately used by a user or the like who is seated facing at the use position of the top plate. It is possible to appropriately perform wiring processing when using a kind, and it is possible to effectively provide a new form of use in this type of flap table.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIGS. 1 and 2, the flap table T of this embodiment is capable of performing a flap operation by the leg 1 in a state where the leg 1 and the leg 1 and 1 are connected to each other. It is comprised from the top plate 2 supported by.

  The leg 1 includes a leg column 11 and a base leg 12 extending in the front-rear direction provided at a position that supports the lower end side of the leg column 11 and is reinforced at a position where the upper ends of the left and right legs 1 are connected. 3 and 4 is attached to a part of the leg 1 (both ends of the horizontal member 13 in this embodiment). It protrudes upward from the body 1. A curtain plate 15 is disposed below the horizontal member 13, and the lower end of the base leg 12 is supported by a caster 12a.

  On the other hand, the top plate 2 has an elliptical shape in plan view as shown in FIGS. 1, 2, and 9, and a pair of movable brackets 21 and a top plate receiving member 22 are attached to the lower surface thereof. The movable bracket 21 is a bag-shaped member arranged along the depth direction Y at a position that supports the lower surfaces of both edges of the top plate 2 in the width direction X, and the top plate receiving member 22 includes a pair of movable brackets 21, It is in the shape of a square pipe provided at a position where the nearest elevations of 21 are connected. The movable bracket 21 and the top plate receiving member 22 are attached to the lower surface of the top plate 2 by screws or the like, and the top plate receiving member 22 supports the lower surface of the top plate 2 along the width direction X to warp the top plate 2. To prevent. An opening 21a is provided at the lower end of the movable bracket 21, and the fixed bracket 14 shown in FIGS. 3 and 4 is inserted therein. The movable bracket 21 is rotatably connected to the fixed bracket 14 via the support shaft m1. ing. The support shaft m1 is located near the center of the top plate 2 along the top plate depth direction Y perpendicular to the axis of the support shaft m1, specifically, from the center position C of the top plate 2 shown in FIG. It is set at a position slightly offset along the depth direction Y. The support shaft m1 provides an axis when the top plate 2 performs the flap operation.

  In the left and right movable brackets 21, there are provided lock pieces 23 that rotate around the support shaft m2 between a locked position and an unlocked position. The portions displaced from the support shaft m2 of the left and right lock pieces 23 are connected by an interlocking shaft 24 extending in parallel along the top plate receiving member 22 as shown in FIG. 2, and this interlocking shaft 24 is driven. Accordingly, the first engaged portion 14a set to the corresponding position of the fixing bracket 14 is set to the first engaged portion 23a set to the lock piece 23 at the use position 2 (P) of the top plate 2 shown in FIG. And the second engaged portion 14b set to the corresponding position of the fixed bracket 14 by the second engaging portion 23b set to the lock piece 23 at the standing position 2 (Q) of the top plate 2 shown in FIG. The top plate 2 is selectively locked at either the use position 2 (P) or the standing position 2 (Q). At the same time, the top plate 2 is supported at the use position 2 (P) at the lower surface thereof supported by the upper surface 14c of the fixing bracket 14, and at the standing position 2 (Q), the lower surface is arranged at a position where it is attached to the rising surface 14d of the fixing bracket 14. Is done. The top plate 2 is parallel to the leg support 11 at the standing position 2 (Q) shown in FIG. As shown in FIG. 2, a rod 25b is connected to the central portion in the width direction of the interlocking shaft 24 while being covered with a cover 25a. The rod 25b extends from the central portion in the depth direction of the top plate 2 to the vicinity of the outer edge. An operation lever 25c is attached to the tip. When the operation lever 25c is pulled, the interlocking shaft 24 is operated, and the lock piece 23 is driven in a direction toward the unlocked position (counterclockwise in FIGS. 3 and 4). The lock piece 23 is elastically pressed by a spring or the like in the direction toward the lock position when the operating force is released.

  In this embodiment, as shown in FIG. 3, if the thickness of the top plate 2 is ignored, the center position C and the center of gravity position M of the top plate 2 substantially coincide with each other in the depth direction Y of the top plate. M is offset in the top plate depth direction Y with respect to the support shaft m1. More specifically, the position of the support shaft m1 in relation to the center of gravity position M of the top plate 3 is an inclined posture in which the center of gravity position M comes directly above the support shaft m1 when the top plate 2 performs a flap operation. Rotation moment toward the use position 2 (P) in FIG. 3 occurs at a shallower angle with respect to the position 2 (R) as a consideration point, and the standing position 2 (FIG. 4) at a deeper angle than that. A rotational moment toward Q) is generated in the top plate 2.

  As shown in FIGS. 2 and 5, the torsion bar 4 is arranged on the axis of the support shaft m1, and the one end 41 side passes through the movable bracket 21 and cannot be rotated to the fixed bracket 14 which is a fixed portion. The other end 42 side is extended in parallel with the adjacent position of the top plate receiving member 22 along the width direction X of the top plate 2, and the vicinity of the other end 42 of the top plate receiving member 22 is extended. It fixes so that it may rotate integrally with the top plate 2 via the fixing piece 43 which is a fixing part on the side. FIG. 5 is a schematic diagram, in which at least both ends 41 and 42 of the torsion bar 4 are formed in a prismatic shape, and one end 41 is inserted into a fixture 44 whose inner space is a square hole, and the outer periphery of the fixture 44 is cylindrical. The fixed bracket 14 is fixed to the fixed bracket 14 by welding or the like, and the movable bracket 21 is attached to the outer periphery of the fixing tool 44 so as to be rotatable around the support shaft m1 and the other end 42 is inserted into the square hole of the fixed piece 43. By doing so, the attachment of the torsion bar 4 and the movable bracket 21 on the support shaft m1 is made compatible. Of course, such a mounting structure of the torsion bar 4 and the movable bracket 21 on the support shaft m1 is merely an example, and is not limited thereto. Since the structure and function of the torsion bar 4 are well known, the details are omitted here. However, when there is no twist between the one end 41 and the other end 42, no elastic force is accumulated and When the other end 42 rotates with the rotation of the top plate 2 and a torsional displacement occurs, a torsional elastic force corresponding to the displacement is accumulated in the torsion bar 4. In this embodiment, there is no torsional displacement when the top plate 2 is in the standing position 2 (Q) shown in FIG. 4, and the top plate 2 is rotated from this position toward the use position 2 (P) shown in FIG. At this time, the torsion bar 4 is set so as to increase the twist and accumulate the elastic force. Of course, it can be set so that there is no torsional displacement when the top plate 2 is in the inclined posture 2 (R) indicated by an imaginary line in these drawings, and in this case, it jumps up from the use position 2 (P). The assisting action by the torsion bar 4 can be obtained for either the operation or the inclining operation from the standing position 2 (Q).

  Such a flap table T is transported to an arbitrary place in an office or the like and used. However, in the approximation, it is becoming common to use electronic devices even in the flap table T. Therefore, it is necessary to prepare for situations where the power supply cannot be secured. Therefore, as shown in FIGS. 1 and 2, the top plate 2 uses a thickness of the top plate 2 below the top plate surface 21 in a partial area in the planar direction. A battery storage unit 6 (6a, 6b) for storing the plate-like battery 5 in a state parallel to 21 is provided. These battery storage parts 6 are located in the respective areas defined by a center line v connecting the centers in the width direction X and a center line w connecting the centers in the depth direction Y near the center of the top panel 2. Each battery storage unit 6 is provided with a rectangular recess 61 provided in a state where a part of the battery is stolen on the back side of the top plate 2, and the recess 61. The battery housing portion 6 is opened to the back surface side by removing the back plate 62. The two battery storage portions 6a and 6b that make a pair along the depth direction Y of the top plate 2 are positioned on substantially both sides of the support shaft m1 as shown in FIG. Between the two battery storage portions 6a and 6b paired in the top plate depth direction Y, as shown in FIGS. 6 and 7, a rectangular wiring space S having a shape in which the top plate 2 is punched in the thickness direction. A part of each battery storage 6a, 6b is open to the wiring space S side along the top plate surface 21.

  An upper portion of the wiring space S is opened as a wiring outlet 26 on the top plate surface 21. As for the wiring outlet 26, as shown in FIG. 7, the wiring outlet 26 is connected to the central portion (center position C) of the top plate along the top plate depth direction Y perpendicular to the support shaft m1, which is the axis that is the center of the flap operation. The center of the outlet 26 is located and can be used as a wiring outlet substantially equally from the top plate edge portions 2m and 2n on both sides along the top plate depth direction Y. And under this wiring outlet 26, the wiring duct 7 is comprised along the top-plate width direction X perpendicular | vertical to the paper surface of FIG. As shown in FIG. 6, the wiring duct 7 is attached to the back surface of the top plate from below so as to receive the top plate receiving member 22, and the bottom wall 71a of the duct material 71 including a U-shaped portion in part, Formed in an upward channel shape at a position where a bent piece 62a provided on one of a pair of back plates 62 paired along the top plate depth direction Y and one rising surface 22a of the top plate receiving member 22 are assembled. A wiring space 7S closed on three sides is formed by walls on both sides in the depth direction Y of the top plate (the bent piece 62a and the vertical surface 22a) and a wall on the lower side of the top plate Z (bottom wall 71a). To the wiring space S. That is, a structure is provided in which wirings can be dropped from the wide wiring space 7 to the narrow wiring space 7S. The wiring duct 7 extends along with a back plate 62 over a position and range that shields the torsion bar 4 and the interlocking shaft 24 from the wiring outlet 26 side. As shown in FIG. 9, the duct members 71 and 71 constituting the left and right wiring ducts 7 are separated from each other, and each wiring duct 7 is opened at a side end 7x and is raised from below. The wiring can be introduced into the wiring duct 7 from there. In the use position 2 (P) of the top plate 2 shown in FIG. 1, the wiring space S and the like can also be used as a central wiring space from the top plate edge portions 2m, 2n on both sides along the top plate depth direction Y. is there

  Here, as described above, the wiring space S is formed by punching out the center of the top plate 2 and the wiring outlet 26, and one of the use areas in the depth direction Y of the top plate 2 across the wiring outlet 26. The brackets 21 and 21 that support both edges in the width direction across the wiring outlet 26 of the top plate 2 are in both regions on the side of the divided use region. Further, the strength of the top plate 2 is effectively prevented from being lowered due to the wiring outlet 26 provided at the center of the top plate 2.

  As shown in FIGS. 7 and 8, the battery 5 used in this embodiment has a thickness 5t embedded in the recess 61 of the top plate 2 and a width dimension substantially equal to the inner dimension 61w of the recess 61 in the top plate width direction. 5w and a depth dimension 5d larger than the inner dimension 61d in the depth direction of the recess 61, the battery 5 is stored in the battery storage portions 6a and 6b and the back plate 62 is attached. The battery 5 is sandwiched between the recessed portion 61 and the back plate 62 and fixed, and the rear edge side of the battery 5 protrudes from the recessed portion 61 and is positioned in the wiring space S in the wiring outlet 26. However, when such a lid structure is adopted, there is a gap or slip between the battery 5 and the inner surface of the recess 61 provided on the back surface of the top plate 2 or between the battery 5 and the inner surface of the back plate 62. In addition, there is a possibility that the battery 5 may rattle in the battery housing portions 6a and 6b due to the flap operation and movement of the top plate 2. Therefore, as shown in FIG. 2, the back plate 62 is pressed against the battery 5 via a friction sheet 63 as a locking member. The friction sheet 63 may be attached to the back plate 62 side in advance. That is, the friction sheet 63 is engaged with the battery 5 when the back plate 62 is attached, and plays a role of holding the position of the battery 5 regardless of the posture of the top plate 2. Of course, the locking member can be provided on the back side of the top plate 2.

  A cord lead-out portion 5a is provided on the rear edge side of the battery 5, and is arranged back-to-back at a predetermined interval from the battery 5 of the same specification at the opposite position. In the pair of battery storage portions 6a and 6b at the opposing positions, the phase of the recess 61 is shifted by the pitch P along the top plate width direction X so that the cord outlets 5a of the pair of batteries 5 do not interfere with each other. . On the upper surface of the rear edge side of the battery 5 protruding to the wiring space S side, a battery display unit 5c using an LED or the like indicating power supply information such as a power supply voltage and a power supply state is provided. As described above, since the battery 5 is buried in the recess 61 of the top plate 2 and is sandwiched between the back surface of the top plate 2, that is, the lower surface of the recess 61 and the back plate 62, FIG. Even if it stands up like this, it is supported on the inner surface of the recess 61 or is sandwiched in the thickness direction to hold a predetermined position.

  In order to close the wiring outlet 26 located above the wiring space S together with the internal wiring space S, a cover 8 is provided as shown in FIG. In this embodiment, the top plate receiving member 22, the channel material 71, the back plate 62 and the like described above are made of steel, and in relation to this, the cover 8 is attached to the wiring outlet 26 at a position attached to the cover 8. A magnet as a holding means (not shown) to be attracted is provided so that the closed state of the cover 8 can be maintained during the flap operation. In FIG. 8, the shaded portion on the right side is the cover 8, and an open portion 8z that opens a part of the wiring space S is provided on the side of the cover 8 in the closed position to enable the drawing of the wiring. A battery display unit 5c that is provided in a part of the battery 5 and displays power supply information such as a power supply capability and a power supply state is visible from the open part 8z.

  As shown in FIGS. 2, 7, and 9, the curtain plate 15 constitutes an upward channel-shaped power supply unit accommodating portion 15b on the lower end side of the plate-like curtain plate main body 15a, and includes a cord reel U1 and a transformer U2. The power supply unit U can be accommodated, and is positioned below the wiring spaces S and 7S. The curtain 15 is located at a position 2 (P) of the top 2 shown in FIG. 3 so as to divide the leg space substantially equally along the top depth direction Y, and the top 2 flaps to the position shown in FIG. When in the standing position 2 (Q) shown, the top plate 2 is in close contact with the side of the curtain plate 15 in parallel. The cord reel U1 shown in FIG. 2 is fixed to the power supply unit storage portion 15b with the outlet port facing upward.

  That is, the flap table T is, for example, in which two people are seated in a face-to-face state on each of the top plate edges 2m and 2n in the top plate depth direction Y shown in FIG. It can be connected to the nearest battery 5 via the wiring space S formed inside the wiring outlet 26 and can receive power.

  In addition, what is shown with the code | symbol D in FIG. 9 is a charging dock. This charging dock D is a self-supporting base 92 attached to a position where the flat hollow plate-like stand 91 forms a T-shape in plan view. The charging dock D has a power supply unit 91b inside the stand 91 and has a plurality of small openings. Has a power supply port 91a.

  The charging dock D has a function of providing the power supply port 91a and a function of collecting the flap tables T. That is, when the table T is moved in a flapped state and the table 2 is brought close to the stand 91 in a posture that is parallel to the stand 91, the base 92 is moved with respect to the casters 12a of the base legs 12 constituting the legs 1 of the flap table T. Stops and stops at a predetermined position. At this position, the battery can be charged while being housed by pulling out the plug from the cord reel U1 housed in the power unit housing portion 15b and inserting it into the power supply port 91a.

  At that time, by bringing the other flap table T closer to the one flap table T in an oblique direction with the top plate 2 standing up, the top plates 2 and 2 are placed at positions where the base legs 12 and 12 interfere with each other. A horizontal stack can be realized in close proximity to each other, and the batteries 5 can be charged by being assembled in an orderly manner near the charging dock D and similarly plugged into the power supply port 91a.

  In addition, the manner of alignment of the flap table T with respect to the charging dock D can be variously modified.

  As described above, the flap table T of the present embodiment has a surface at the center in the depth direction Y of the top plate that is perpendicular to the support shaft m1, which is the axis that is the center of the flap operation, with respect to the top plate 2 that performs the flap operation. Since the wiring outlet 26 is provided on the top, access from each part can be performed evenly, starting from the top plate edges m and n located on both sides in the depth direction Y of the top plate, and the concentrating process is easy. Thus, it is possible to effectively provide an environment in which electronic devices can be easily used even with a flap table.

  At that time, by providing such a wiring outlet 26 in the center of the top plate 2, a part of the use area in the top plate depth direction Y is divided across the wiring outlet 26. Since both edges in the width direction X across the take-out port 26 are supported by the legs 1 and 1 via the brackets 26 and 26 arranged so as to straddle the divided use region, the strength of the top plate 2 Can be effectively secured.

  In this case, the support shaft m1, which is the axis that is the center of the flap operation, is also set in the vicinity of the center of the top plate 2 along the top plate depth direction Y, so that the top plate 2 jumps greatly during the flap operation. In addition, even if the wiring outlet 26 is provided in the center along the top plate depth direction Y, the vertical displacement of the wiring outlet 26 is reduced during the flap operation. For this reason, it is possible to prevent the wiring from being dragged when, for example, the wiring is drawn into the wiring outlet 26 from the outside, and it is difficult to apply a centrifugal force to the wiring equipment, so that an appropriate wiring state is obtained. Can be maintained.

  Specifically, the center position C in the depth direction Y of the top plate 2 is offset along the top plate depth direction Y with respect to the position of the support shaft m1, which is the axis that is the center of the flap operation. Even if the wiring outlet 26 is provided in the center in the depth direction of the plate 2, the torsion bar 4 and the like are effectively arranged on the axis of the support shaft m1 without interfering with the wirings entering and exiting the wiring outlet 26. It becomes possible.

  In this case, the curtain plate 15 is provided below the central portion (center position C) in the depth direction Y of the top plate, and the top plate 2 is configured to stand parallel to the side of the curtain plate 15 during the flap operation. A configuration in which the curtain plate 15 is partitioned and arranged at a central position that does not interfere with the space of the lower limbs when used face-to-face and a configuration in which interference with the top plate 2 is avoided during the flap operation can be achieved.

  In addition, since the wiring space 7S is formed in the wiring outlet 26 so that at least two sides are closed along the top plate depth direction Y, the wiring drops from the wiring space 7S even if the flap operation is performed. This can be effectively prevented.

  In particular, in this embodiment, the edge in the width direction of the top plate 2 is supported by the leg 1 via the movable bracket 21 and the movable brackets 21 and 21 are connected by the top plate receiving member 22. Since the wiring duct 7 for closing the wiring space 7S is configured using the plate receiving member 22, it is possible to effectively form the wiring space 7S with a stable support state without unnecessarily increasing the number of parts. it can.

  Further, a lock piece 23 operable between the lock position and the non-lock position is provided in the left and right movable brackets 21, 21, and the interlock between the lock pieces 23, 23 extends in parallel along the top plate receiving member 22. The shaft 24 is connected, both the lock pieces 23, 23 are engaged with a part of the leg 1, and the top plate 2 is selectively locked to either the use position or the standing position. Since the interlocking shaft 24 is arranged over a range where the interlocking shaft 24 is shielded from the wiring outlet 26, it not only forms the wiring space 7S in the wiring duct 7, but also plays a role of improving the appearance of the wiring outlet 26. Can be made.

  Furthermore, since the cover 8 is arranged at a position for opening and closing the wiring outlet 26 on the top plate surface 21 in a state where the cover 8 can be kept closed during the flap operation via the magnet as the holding means. It is possible to effectively prevent the cover 8 from falling off during operation, and to effectively present a configuration in which a wiring function is brought into the center of the flap table T.

  In this case, since an opening 8z that opens a part of the wiring space S is provided on the side of the cover 8 at the closed position so that the wiring can be pulled out, the top plate surface 21 is covered with the cover 8 closed. It can be effectively used as a work surface of a personal computer or the like.

  The specific configuration of each unit is not limited to the above-described embodiment.

  For example, in order to exhibit the function of the present invention, the top plate does not have to be elliptical, and may be rectangular or polygonal.

  In addition to the magnet, the cover holding means may employ a structure that elastically engages an elastic claw with an appropriate portion.

  Furthermore, the axis as the operation center does not necessarily have to be a fixed position from start to finish, and may move. Further, when a flap operation is given by a link or the like, a virtual axis may be used.

  Furthermore, as shown in FIG. 10, even if the top plate 102 is completely divided and the wiring outlet 126 is provided therebetween, both edges in the width direction X across the wiring outlet 126 of the top plate 102 are Even if the bracket 121 is arranged so as to extend over both divided regions and the bracket 121 is supported by the leg body 101, the wiring outlet 126 is effectively provided in the center of the top plate 102 while ensuring the top plate strength. Can be formed.
