  By combining these furniture with a top plate, the relative position of the top plate with respect to the base can be changed, and when trying to provide furniture with a top plate having an outlet function, the conventional one changes the relative position of the top plate. In this case, it is necessary to remove a part of the support from one fitting hole and re-attach it to the other fitting hole, and the operation of changing the relative position of the top plate cannot be easily performed. In addition, since the outlet or wiring outlet is provided on the opposite side of the top plate, there is always a problem that the usage area of the top plate is damaged by the space for the outlet or the opening size of the wiring outlet. . Therefore, in order to eliminate the latter problem, a mode in which an outlet is provided on the base is also conceivable.

  However, when an outlet is provided on the base, when the top plate is moved relative to the base together with the support while the cord of the electric device placed on the top plate is connected to the outlet, the outlet and the top plate Since the relative position (relative distance) changes, the longer the distance the top plate moves relative to the base, the more the top plate moves away from the outlet, the more connected the outlet or the outlet. If an excessive pulling force is applied to the cord and the top plate moves in the direction in which the distance between the top plate and the outlet gets closer, the extra length of the cord spreads over the top plate more than necessary and the use area is damaged. . Furthermore, as a fatal problem, when the top plate is moved relative to the base together with the support while the cord of the electrical device placed on the top plate is connected to the outlet, the relative movable range is the length of the cord. And the degree of freedom in use is extremely low. In order to avoid such problems, when the top plate is moved relative to the base, the cord is temporarily removed from the outlet and then re-inserted after the movement, or the base in order to reduce the distance between the outlet and the top plate. Although the mode of changing the mounting position of the outlet with respect to the base is also conceivable, such a thing requires the insertion and removal work of the cord to the outlet or the attachment and detachment work of the outlet to the base every time the relative position of the top plate to the base is changed. It is not easy to use and lacks practicality. As described above, the aspect in which the outlet is provided on the base cannot be flexibly adapted to the change in the relative position of the top plate with respect to the base, and cannot be adapted to various working styles using various electric devices. There is.

  The present invention has been made paying attention to such a problem, and solves the various problems described above based on an unprecedented novel idea of attaching an outlet device to a support that supports a base. It is for the purpose.

That is, the support of the present invention is movably supported by a base extending in a predetermined direction and supports the top plate. The support includes an outlet accommodating portion that can accommodate an outlet device, and is attached to the base. In any relative position to be obtained, the outlet device accommodated in the outlet accommodating portion can be accessed.

  Here, the outlet device may be of any type such as a power outlet or an information outlet (for data communication, facsimile, telephone, etc.). Further, the term “outlet” is a concept that encompasses all devices that connect electric devices, information devices, and the like to a power source, an information communication network such as a LAN, a telephone line, and the like via a cord.

In such a case , since the support according to the present invention supporting the top plate is attached to the outlet device, the relative position of the top plate with respect to the base is changed along the extending direction of the base. the relative positions of the top plate and the outlet device also does not change substantially, relative movement as a result, the top plate relative to the base along with still the support connecting the cord of an electrical appliance which is placed on the top plate to the outlet device When doing so, it is possible to easily avoid situations in which an excessive pulling force acts on the outlet device and the cord connected to the outlet device, or the extra length of the cord spreads more than necessary on the top plate and impairs the use area. . Moreover, when relatively moving the top plate to the base along with the left support connecting the cord of an electrical appliance which is placed on the top plate to an electrical outlet, also its relative movable range depends on the length of the cord In addition, since the outlet device accommodated in the outlet accommodating portion can be accessed at any relative position that can be taken with respect to the base, the degree of freedom in use is greatly improved.

In this way, by adopting the novel concept of giving the outlet function to the support, it is no longer necessary to plug and unplug the cord from the outlet device, which was conventionally required every time the position of the top plate relative to the base is changed. It is easy to use and can flexibly respond to changes in the relative position of the top plate with respect to the base.

  As a preferred embodiment, there is a mode in which a frame body having an inner space substantially closed in a plan view is provided, and the outlet accommodating portion is provided in the frame body.

  Further, the outlet housing portion is provided in one frame constituting the frame body, and the one frame has an upper surface portion provided with the outlet housing portion and a lower surface portion facing the upper surface portion in the height direction. If a reinforcing body is interposed between the upper surface portion and the lower surface portion, the deformation of one frame is prevented and the operation of inserting / removing the cord with respect to the outlet of the outlet is performed more accurately. be able to.

  In order to realize the reinforcing body with a simple structure and further increase the reinforcing strength by the reinforcing body, the reinforcing body is a plate-like member arranged in an upright position between the upper surface portion and the lower surface portion. In addition, a stepped portion that is bent substantially along the shape of the outlet accommodating portion in plan view may be provided at a position positioned in the vicinity of the outlet accommodating portion.

In addition, the top plate to horizontally pivotally supported, the top plate is, it is a plan view shape of the rotating base end side those in an arc around the pivot axis of the top plate, the top plate If the outlet device accommodated in the outlet receptacle is exposed between the pivot base end of the top plate and the base at any turning angle that can be taken by the top plate , Is also accessible to the outlet device, and when the top plate is turned horizontally with the cord of the electrical device placed on the top plate connected to the outlet device, the relative distance between the electronic device and the outlet device However, it is possible to effectively avoid the occurrence of problems in wiring processing such as an excessive pulling force acting on the outlet device or the cord.

  If the outlet receptacle is a recess into which the outlet device can be fitted, the structure of the outlet receptacle can be simplified.

  In particular, the outlet device is a outlet unit including a plurality of outlet bodies, outlets provided in each outlet body, and a base body for connecting the outlet bodies, and the outlet housing portion includes the outlet unit. In order to accommodate each outlet body and the base body individually, the outlet unit is provided with an outlet body housing section capable of accommodating each outlet body and a base body housing section capable of accommodating the base body. Even so, a good mounting state can be realized.

  Further, the furniture with a top plate of the present invention includes the above-described base having a guide portion provided continuously along the extending direction, and the support body supported by the base so as to be slidable using the guide portion. And a top plate supported by the support body so as to be horizontally rotatable.

As described above, according to the present invention, by adopting a novel concept of providing an outlet function to the support, it is possible to change the relative position of the top plate with respect to the base. It eliminates the need for plugging / unplugging and so on, is highly practical, can flexibly respond to changes in the relative position of the top plate with respect to the base, and can be used in a variety of working styles using various electrical devices.

(See FIG. 15). In this assembled state, the retractable body 4C1 is fixed to the upper surface side of the operation lever 4D2, and the link pressing body 4D1 is fixed to the lower surface side of the operation lever 4D2. In this assembled state, the link pressing body 4D1 and the retracting body 4C1 together with the operation lever 4D2 can be turned horizontally around the operation lever shaft 4D3.

  Next, the usage method of this desk 1 and operation | movement and an effect | action of each mechanism are demonstrated.

  First, during normal use, in order to restrict the sliding movement of the support 4 and the turning of the top plate 5, each slide switching mechanism 4B is set in a movement restricted state and the turning switching mechanism 4C is set in a turning restricted state.

  When each slide switching mechanism 4B is in the movement restricted state, as shown in FIGS. 3 and 7, the upper contact body 4B1 (specifically, the front surface of the upper protrusion 4B12) is given priority over the upper rolling body 4B3. Part) abuts against the opening side standing wall 21a of the upper rail groove 21, and the lower side abutting body 4B2 abuts against the rear side standing wall 22b of the lower rail groove 22 in preference to the lower rolling body 4B4. As a result, the sliding movement of the support 4 with respect to the base 2 and, consequently, the sliding movement of the top plate 5 with respect to the base 2 are restricted.

  In the present embodiment, the lower-side contact body 4B2 is attached to the distal end portion of the advance / retreat member 4B21 that can advance and retreat with respect to the frame body 4A as described above, and the slide switching mechanism 4B controls the movement. In this state, a jig such as a flat-blade screwdriver is inserted into the operation receiving portion 4B212 of the advance / retreat member 4B21 to apply a predetermined operation force, thereby moving the advance / retreat member 4B21 forward and backward. It is possible to adjust the relative position of the side contact body 4B2. As a result, the relative angle of the support 4 with respect to the base 2 can be finely adjusted, and the top plate 5 supported by the support 4 can be set to have a substantially horizontal posture in a normal use state. That is, the lower side contact body 4B2 and the advance / retreat member 4B21 constitute a relative angle adjustment mechanism capable of adjusting the relative angle of the support body 4 with respect to the base 2.

  Further, when the turning switching mechanism 4C is in the turning restricted state, as shown in FIG. 3 and FIG. 15, the retractable body 4C1 positioned at the swivelable position is moved to the outer stopper disk 53 of the turning stopper disk 53 by the swaging claw 4C112. While gripping 533 and pulling it downward, the lower surface of the top plate main body 51 is supported at a plurality of points by the respective priority support portions 4A6. As a result, horizontal turning of the top plate 5 relative to the support 4 is restricted. In this way, when each slide switching mechanism 4B is in the movement restricted state and the turning switching mechanism 4C is in the turning restricted state, as shown in FIG. 2, the operation lever 4D2 of the switching operation interlocking mechanism 4D is connected to the handle portion 4D21. The link pressing body 4D1 of the switching operation interlocking mechanism 4D is positioned at a normal position whose longitudinal direction is substantially orthogonal to the longitudinal direction of the base 2, and the upper side link pressing rolling element 4D5 provided at the tip of each pressing body main body 4D12. And the lower link pressing rolling elements 4D6 are in contact with the proximal end portion 4B52 region of the upper link 4B5 or the proximal end portion 4B62 region of the lower link 4B6, and do not press the links 4B5, 4B6. It is positioned at the non-pressing position.

  On the other hand, when the relative position and relative angle of the top plate 5 with respect to the base 2 are changed, each slide switching mechanism 4B is switched from the movement restricted state to the movement permitted state, and the turning switching mechanism 4C is turned from the turning restricted state to the turn permitted state. It is necessary to switch to. In this case, the user holds the handle portion 4D21 of the operation lever 4D2 at the normal position, and applies an operation force to pull it forward (user side) regardless of the forward and reverse directions.

  Based on this operating force, the operating lever 4D2 horizontally turns in one of the forward and reverse directions (for example, clockwise direction) around the operating lever shaft 4D3 together with the link pressing body 4D1 and the retracting body 4C1 (see FIG. 18). Accordingly, the link pressing body 4D1 is provided with the upper side link pressing rolling element 4D5 and the lower side link pressing provided at the distal end portion of any one pressing body body 4D12 from the non-pressing position. The rolling elements 4D6 are respectively pressed against the proximal end portions 4B52 and 4B62 of the respective links 4B5 and 4B6 while being brought into contact with the proximal end portion 4B52 of the upper link 4B5 or the proximal end portion 4B62 of the lower link 4B6. Rotate to one pressing position. As the link pressing body 4D1 turns, the upper link 4B5 and the lower link 4B6 of each slide switching mechanism 4B whose base end portions 4B52 and 4B62 are pressed by the link pressing body 4D1 are linked to each other to link the link shaft 4B7. Rotate around the center. Then, as shown in FIGS. 18 to 20, the upper link 4B5 and the lower link 4B6 facing each other in the height direction in each slide switching mechanism 4B rotate about a common link shaft 4B7, thereby The upper rolling element 4B3 provided at the distal end portion 4B51 of the side link 4B5 moves toward the opening side standing wall 21a of the upper rail groove 21, and the lower rolling element 4B4 provided at the distal end portion 4B61 of the lower link 4B6. Moves toward the rear side standing wall 22b of the lower rail groove 22. As a result, each slide switching mechanism 4B releases the contact state of the upper contact body 4B1 with respect to the opening-side standing wall 21a of the upper rail groove 21 and moves the upper rolling element 4B3 to the opening side of the upper rail groove 21. The lower rolling body 4B4 is lifted to the rear side of the lower rail groove 22 by bringing the lower rolling body 4B4 into contact with the standing wall 21a and releasing the contact state of the lower side contact body 4B2 with the rear side standing wall 22b of the lower rail groove 22. The movement is allowed to be brought into contact with the wall 22b. Thereby, it becomes possible to slide the top plate 5 together with the support 4 with respect to the base 2, and the relative position of the top plate 5 with respect to the base 2 can be changed along the extending direction of the base 2.

  Since the support body 4 according to the present embodiment has the outlet device C attached thereto, the top plate 5 is moved relative to the base 2 by sliding the top plate 5 with respect to the base 3 together with the support body 4. Even when the position is changed, the relative position between the outlet device C attached to the frame body 4 </ b> A and the top plate 5 is not substantially displaced, and the space between the rotation base end side of the top plate 5 and the base 2 is not changed. The outlet device C to be exposed can be accessed.

  In the present embodiment, the rail grooves 21 and 22 are formed from one end to the other end of the base 2, so that the slide switching mechanism 4 </ b> B is supported by sliding the support 4 in a movement-permitted state. It is also possible to move the body 4 together with the top plate 5 to another adjacent base 2, or to remove the support body 4 from the base 2 together with the top plate 5. In other words, the support 4 once removed from the base 2 can be attached to the base 2 again using the rail grooves 21 and 22 by setting the slide switching mechanism 4B to the movement-permitted state. That's what it means.

  Further, the retractable body 4C1 of the turning switching mechanism 4C together with the operation lever 4D2 based on the operation force (the operation force grasping the handle portion 4D21 of the operation lever 4D2 and pulling it forward (user side) regardless of the forward or reverse direction). Also, in the internal space 4AS of the frame body 4A, the swivel movement is made from the swivelable position to a swivel release position where the swivel stopper disk 53 is released from the swivel state with respect to the outer stopper disk 533 (see FIG. 18). As a result, the turning switching mechanism 4C releases the swiveling stopper disc 53 from the retractable body 4C1 and enters a turning permission state in which the top plate 5 is allowed to turn horizontally, and the top plate 5 is placed horizontally around the turning shaft 5a. By turning, the posture in which the longitudinal direction of the top plate 5 is substantially orthogonal to the longitudinal direction of the base 2 (see FIG. 2), or the longitudinal direction of the top plate 5 is substantially parallel to the longitudinal direction of the base 2. (Refer to FIG. 21, and FIG. 21 shows the state where the operation lever 4D2 is positioned at the normal position.) The turning angle posture of the top plate 5 with respect to the base 2 can be appropriately selected.

  Therefore, in this embodiment, the planar view shape of the rotation base end side (rear end side) of the top plate body 51 is set to a substantially semicircular arc shape centering on the turning shaft 5 a of the top plate body 51. Therefore, when the top plate 5 is horizontally turned with respect to the support 4, the outlet device C housed in the outlet housing portion 4 </ b> A 312 a is connected to the rotation base end side of the top plate 5 at any turning angle that the top plate 5 can take. It is exposed to the base 2 and can access the outlet device C.

  Even when a manipulation force for pulling the manipulation lever 4D2 in the normal position in the reverse direction (counterclockwise direction) is applied, as shown in FIG. 22, each slide switching mechanism is actuated by the switching operation interlocking mechanism 4D. 4B can be switched from the movement restricted state to the movement permitted state, and the turning switching mechanism 4C can be switched from the turning restricted state to the turn permitted state. That is, when the operation lever 4D2 is horizontally turned counterclockwise from the normal position, the link pressing body 4D1 and the retracting body 4C1 horizontally turn counterclockwise around the operation lever shaft 4D3 together with the operation lever 4D2. From the non-pressing position, the pressing body 4D1 moves the upper side link pressing rolling element 4D5 and the lower side link pressing rolling element 4D6 provided at the tip of the other pressing body body 4D12 of the paired pressing body bodies 4D12 upward. Turn to the second pressing position that presses the proximal end portion 4B52, 4B62 vicinity region of each link 4B5, 4B6 while being in contact with the proximal end portion 4B52 vicinity region of the side link 4B5 or the proximal end portion 4B62 vicinity of the lower side link 4B6 Moving. Thereafter, the slide switching mechanism 4B is allowed to move by the same operation and action as described above, and the turning switching mechanism 4C is allowed to turn. Further, when the turning switching mechanism 4C is in the turning allowable state, the top plate 5 can be rotated in the direction of lifting with respect to the support 4 using the hinge mechanism H.

  On the other hand, when each slide switching mechanism 4B is switched from the movement-permitted state to the movement-restricted state, and when the turn switching mechanism 4C is switched from the turn-permitted state to the turn-restricted state, an operation force that returns the operation lever 4D2 to the normal position is applied.

  Based on this operating force, the operating lever 4D2 rotates horizontally with the link pressing body 4D1 and the retracting body 4C1 around the operating lever shaft 4D3 in the direction opposite to that during the switching operation. As a result, the link pressing body 4D1 pivots from the first pressing position or the second pressing position to the non-pressing position. Along with the turning movement of the link pressing body 4D1, the links 4B5 and 4B6 of the slide switching mechanisms 4B are interlocked to switch the slide switching mechanism 4B from the movement restricted state to the movement permitted state around the link shaft 4B7. Is rotated in the opposite direction, so that the upper rolling element 4B3 provided at the distal end portion 4B51 of the upper link 4B5 moves in a direction away from the opening-side standing wall 21a of the upper rail groove 21 and is moved downward. The lower rolling element 4B4 provided at the distal end portion 4B61 of the side link 4B6 moves in a direction away from the rear side standing wall 22b of the lower rail groove 22. As a result, the support 4 moves in the direction of sinking due to the weight of the support 4 itself and the weight of the top plate 5, and each slide switching mechanism 4 </ b> B moves to the opening side of the upper rail groove 21 as shown in FIG. 5. The contact state of the upper rolling element 4B3 with respect to the standing wall 21a is released, the upper contact body 4B1 is brought into contact with or pressed against the opening side standing wall 21a of the upper rail groove 21, and the lower side of the lower rail groove 22 is placed. The state where the lower rolling element 4B4 is brought into contact with the side upright wall 22b is released, and the lower side abutting body 4B2 is brought into contact with or pressed against the rear side upright wall 22b of the lower rail groove 22. Thereby, the sliding movement of the support body 4 with respect to the base 2 and by extension, the top plate 5 is regulated. The rotation of the operation lever 4D2 at the time of the switching operation is such that the link pressing rolling bodies 4D5 and 4D6 provided on the link pressing body 4D1 are formed in the concave portions 4B56 and 4B62 formed on the base end portions 4B52 and 4B62 of the links 4B5 and 4B6, respectively. By fitting in 4B66 (see FIGS. 11 and 12), further rotation in the same direction is restricted.

  Further, on the basis of the operation force (operation force for returning the operation lever 4D2 to the normal position), the retractable body 4C1 of the turning switching mechanism 4C is also turned and moved from the retraction release position to the retraction possible position together with the operation lever 4D2. When the retractable body 4C1 is swung from the retracting position to the retractable position, the operation of the retracting guide 4C11a provided on the retracting claw 4C112 of the retractable body 4C11 facilitates the retraction operation with respect to the revolving stopper disk 53. In addition, the operation of the retracting guide 4C12a provided in the retracting body 4C12 of the retracting body 4C1 can smoothly perform the retracting operation of the frame body 4A with respect to the retracting body pressing frame 4A35. . In the present embodiment, in the process of switching the turning switching mechanism 4C from the turning permission state to the turning restriction state, the submerged body 4C12 is brought into the lower part of the retracting body pressing frame 4A35 while being brought into contact with or pressed against the retracting body pressing frame 4A35. Accordingly, the retractable body 4C11 is pulled downward, and the turning stopper disk 53 can be retracted together with the retractable body 4C11. As a result, the top plate 5 integrally provided with the turning stopper disk 53 is also drawn downward, and the lower surface of the top plate body 51 is brought into pressure contact with the priority support portion 4A6, and a good support state of the top plate 5 is ensured. (See FIGS. 3 and 15). In this way, the turning switching mechanism 4C is switched from the turning permission state to the turning restriction state based on the operation force.

  When the turning switching mechanism 4 </ b> C is in the turning restricted state, the top plate 5 is in a state in which it cannot turn in the direction of lifting with respect to the support body 4 around the hinge axis H <b> 1 of the hinge mechanism H as shown in FIG. 8. In the present embodiment, the slide switching mechanism 4B is provided with an auxiliary rolling element 4B9 that can rotate around a horizontal axis that can contact the bottom wall 21c of the upper rail groove 21 (see FIG. 7).

  As described above, the support body 4 according to the present embodiment includes the outlet accommodating portion 4A312a that can accommodate the outlet device C. Therefore, the support body 4 is a case where the support body 4 is relatively slid to any position along the extending direction of the base 2. However, since the outlet device C accommodated in the outlet accommodating portion 4A312a is exposed between the base 2 and the top plate 5, the relative position (relative distance) between the outlet device C and the top plate 5 is not substantially changed. When the top plate 5 is moved relative to the base 2 together with the support 4 while the cord of the electric device placed on the top plate 5 is connected to the outlet device C, the outlet device C and the cord connected to the outlet device C are connected. Therefore, it is possible to easily avoid a situation in which an excessive pulling force acts on the top plate 5 or an excessive length of the cord spreads on the top plate 5 more than necessary and the use area is damaged. Further, when the top plate 5 is moved relative to the base together with the support while the cord of the electric device placed on the top plate 5 is connected to the outlet, the relative movable range depends on the length of the cord. In addition, since the outlet device C accommodated in the outlet accommodating portion 4A312a can be accessed at any possible relative position with respect to the base 2, the degree of freedom in use is greatly improved.

  As described above, the novel structure of providing the outlet function to the support body 4 eliminates the need for connecting / disconnecting the cord to / from the outlet device C, which has been conventionally required, whenever the relative position of the top plate 5 with respect to the base 2 is changed. It is easy to use, can flexibly respond to changes in the relative position of the top plate 5 with respect to the base 2, can handle various working styles that make full use of various electric devices, and has excellent practicality and versatility. Become.

  Further, since the outlet housing portion 4A312a is provided in the frame body 4A having an internal space that is substantially closed in a plan view, the frame body 4A is used when the electric device cord is inserted into or removed from the outlet device C housed in the outlet housing portion 4A312a. Effective load resistance is demonstrated, and the cord can be inserted and removed accurately. Moreover, weight reduction of the support body 4 can be effectively achieved by using the frame body 4A having an internal space.

  In the present embodiment, an outlet accommodating portion 4A312a is provided on the upper piece 4A312 of the rear frame main body 4A31, and the rear frame main body reinforcing body 4A33 is interposed between the upper piece 4A312 and the lower piece 4A313 facing in the height direction. Therefore, the rear frame main body reinforcing body 4A33 prevents the rear frame head short 4A31 from being deformed, and maintains a good mounting state of the outlet device 1 with respect to the outlet accommodating portion 4A312a. Demonstrate effective load resistance.

  In particular, the rear frame main body reinforcing body 4A33 is a plate-like member disposed in an upright position between the upper piece 4A312 and the lower piece 4A313, and is located in a region positioned in the vicinity of the outlet accommodating portion 4A312a. Since the step portion 4A331 bent substantially along the plan view shape of the housing portion 4A312a is provided, the rear frame main body reinforcing body 4A33 can be realized with a simple structure, and the step portion 4A331 functions as a rib to further improve the strength. Can be planned.

  Moreover, the planar view shape of the rotation base end side of the top plate 5 that can be swiveled horizontally with respect to the support body 4 is set to a substantially semicircular arc shape centering on the turning shaft 5 a of the top plate 5. Since the outlet device C accommodated in the outlet accommodating portion 4A312a is exposed between the rotation base end side of the top plate 5 and the base 2 at any possible turning angle, the top plate 5 is at any turning angle. Even if it exists, it can access with respect to the outlet apparatus C, and can flexibly face various layout changes.

  The outlet accommodating portion 4A312a is realized by a recess (specifically, a combination of a through hole and a bottomed recessed groove) into which the outlet device C can be fitted, thereby contributing to simplification of the structure of the outlet accommodating portion 4A312a.

  In addition, the outlet device C includes a plurality of outlet bodies CA1 and CB1, insertion ports CA2 and CB2 provided in the outlet bodies CA1 and CB1, respectively, and a base body C3 that connects the outlet bodies CA1 and CB1. The outlet receptacle unit 4A312a includes outlet body receptacles 4A312aa and 4A312ab capable of accommodating the respective outlet bodies CA1 and CB1, and a base body receptacle 4A312ac capable of accommodating the base body C3. Therefore, even if the outlet device is an outlet unit, each outlet body and the base body are individually accommodated, so that a good mounting state can be realized.
