Description

  The present invention relates to a base that supports furniture components such as a top board.

2. Description of the Related Art Conventionally, furniture in which furniture components such as a top board are supported on a long base so that the relative arrangement position of the furniture components with respect to the base can be changed is known. As an example, there is a mode in which the relative position of the top plate with respect to the base can be changed by appropriately changing the mounting position of the support that supports the top plate along the longitudinal direction of the base. Specifically, the base plate can be repositioned relative to the base by forming a plurality of fitting holes with a predetermined pitch in the base, and changing the mating position of the support. (For example, refer to Patent Document 1).
JP 2004-159713 A (see FIG. 1)

  However, when changing the relative position of the top plate with respect to the base, the conventional one once lifts the support body together with the top board to release the fitting state between a part of the support body and the fitting hole, It is necessary to move the support to a desired position while lifting it, and to lower the top plate and the support so that a part of the support is inserted into the fitting hole nearest to the position or the position. There was a problem that the relative position of the top plate could not be easily and accurately changed. In addition, although the relative position of the top plate and the support body with respect to the base depends on the position where the fitting holes are formed, since the fitting holes are formed at a predetermined pitch in the base, the top plate and the support body with respect to the base There is a problem that the relative position cannot be finely adjusted. Furthermore, furniture components that can be attached to and supported by the base are limited to those having an insertion portion that can be fitted into the fitting hole and capable of changing the relative arrangement position with respect to the base. There is a problem that it is impossible to meet the demand for mounting and supporting furniture components whose arrangement positions cannot be changed, and it is not possible to sufficiently cope with a wide variety of recent working styles.

  The present invention has been made paying attention to such problems, and the main purpose thereof is to make it possible to mount and support not only furniture components whose arrangement position can be changed but also furniture components whose arrangement position cannot be changed. It is to provide a base that can cope with various working styles using a plurality of different types of furniture components.

  That is, the base of the present invention is a base that extends in a predetermined direction, and includes a rail-shaped attachment portion that is continuous along the extension direction. The attachment portion supports the top plate and extends along the attachment portion. The top plate movable support that can be slidably moved, the top plate fixed support that supports the other top plate and cannot be slid along the mounting portion, supports the optional members, and depends on the position of each top plate And an optional movable support that is slidable along the mounting portion.

  If this is the case, there are a wide variety of furniture components (top plates, optional members, etc.) that can be mounted and supported via the mounting portion. By attaching and supporting, in one working area using the base, it is possible to arrange a top plate that can change the relative position with respect to the base and a top plate that cannot change the relative position, An area where layout can be changed and an area where layout cannot be changed or difficult can be formed, and can be used in both environments where layout changes are frequently made and environments where layout changes are not made. It will be rich. In addition, by sliding the optional movable support in accordance with the placement positions of these top plates, the position of the option member supported by the optional movable support is closely related to the placement position of the top plate. It is possible to flexibly cope with the user's working style and various layout changes. Moreover, since the top plate movable support body and the optional movable support body are slidable, there is no need to lift and lower the support body and the support object as in the prior art. The relative position of the top plate and the optional member can be changed very easily through the support. In addition, since it can be slid along a rail-shaped mounting portion that is continuous in the extending direction, the relative position change of the top plate movable support and the optional movable support relative to the base can be adjusted steplessly. It is possible to finely adjust the relative positions of the top plate and the optional member with respect to the base, and it is excellent in practicality.

  In this way, not only furniture components whose arrangement position can be changed with respect to a single base but also furniture components whose arrangement position cannot be changed can be attached and supported, and a plurality of different types of furniture components are used. It will be able to respond flexibly to various working styles.

  In particular, if the option fixing support body that supports another option member different from the option member and is not slidable along the attachment portion can be attached to the attachment portion, the furniture component that can be attached and supported. The number of types can be further increased, and further expansion of workstations can be achieved.

  Moreover, if it has a substantially rectangular cross section and is provided with the mounting portions on the upper surface portion and both side surface portions, the top plate movable support body and / or the top plate fixed support body are respectively attached to the mounting portions of the side surface portions. By attaching, a top plate can be disposed in each region with the base as a boundary using each support. In addition, when the top plate movable support body can be attached to the side surface portion and the optional movable support body can be attached to the upper surface portion, when these movable support bodies are slid, Interference can be avoided, and the top plate supported by each movable support and the optional member can be smoothly slid.

  As a preferred embodiment, an embodiment in which the attachment portion is a rail groove can be mentioned.

  In order to increase rigidity and exhibit sufficient load resistance, the base body having a substantially rectangular cross-sectional shape and an upper wall of the base body are integrally provided along the extending direction of the base body. The mounting portion may be a rail groove formed between the adjacent upstanding walls. If this is the case, the upright walls that make up the rail groove also function as ribs, so that effective load resistance against the load on the top plate, optional members, etc. is demonstrated, and support is provided by deforming the base. Deterioration of state and malfunction can be avoided. In addition, since the rail groove is formed by using the standing wall that contributes to the rigidity improvement of the base, it is not necessary to provide a dedicated member for increasing the rigidity separately from the rail groove, and the structure is simplified and the number of parts is reduced. Reductions can be achieved at the same time.

  Further, as having substantially the same effect, a base body having a substantially rectangular cross section in cross section, and a plurality of horizontal walls provided integrally with the side wall of the base body and extending along the extending direction of the base body. The aspect which comprises and forms the rail groove | channel which is the said attaching part between the said adjacent horizontal walls is mentioned.

  Further, in order to be able to flexibly cope with various layouts, an aspect in which a plurality of attachment portions are provided substantially parallel to each other on the upper surface portion, or a plurality of attachment portions are substantially mutually attached to the side surface portion. A mode provided in parallel may be applied.

  In particular, if a reinforcing body having a substantially cylindrical cross section is provided between the rail grooves adjacent to each other in the height direction, deformation of each rail groove is prevented, and a good support state of each support body by these rail grooves is maintained. can do.

  As described above, according to the present invention, there are various types of furniture components that can be mounted and supported, and can be flexibly adapted to various working styles, which is extremely useful for realizing a high-performance workstation. It becomes.

That is, in the present embodiment, the upper side link is formed in one region (specifically, the outer region) with a virtual straight line L passing through the center of the link shaft 4B7 and substantially orthogonal to the slide movement direction as a boundary. The front end 4B51 of 4B5 is positioned, and the front end 4B61 of the lower link 4B6 is positioned in the other region (specifically, the inner region).

  The support body 4 in the present embodiment is provided with a pair of slide switching mechanisms 4B having such a configuration at positions separated along the slide movement direction.

  As shown in FIGS. 3 and 4, the switching operation interlocking mechanism 4D includes a link pressing body 4D1, and an operation lever 4D2 that is integrally attached to the link pressing body 4D1 and can be horizontally turned around the operation lever shaft 4D3. It is equipped with.

  The link pressing body 4D1 has a non-pressing position where the link pressing body 4D1 is in contact with or attached to the region near the base end of each link 4B5, 4B6 and does not press the link 4B5, 4B6, and the region near the base end of each link 4B5, 4B6. It can move between the pressing positions where pressing is possible. This link pressing body 4D1 is provided with a bifurcated pair of pressing bodies that can directly contact or abut the base ends 4B52 and 4B62 of the links 4B5 and 4B6. An upper link pressing rolling element 4D5 that can press the base end of the upper link 4B5 of each slide switching mechanism 4B with a predetermined distance in the vertical direction, and the base end of the lower link 4B6 of each slide switching mechanism 4B The lower side link pressing rolling elements 4D6 that can press are respectively held rotatably around the vertical axis.

  The operation lever 4D2 is provided with a linear handle portion that can be held by a user at one end portion (front end portion) and a supported portion supported by the link pressing body 4D1 at the other end portion (rear end portion). It is a shape.

  The link pressing body 4D1 and the operation lever 4D2 are assembled integrally and can be turned horizontally around a common operation lever shaft 4D3.

  When each slide switching mechanism 4B is in the movement restricted state, as shown in FIG. 6, the upper contact body 4B1 (specifically, the front surface portion of the upper protrusion 4B12) is given priority over the upper rolling body 4B3. ) 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 side rolling element 4B4. As a result, the sliding movement of the top movable support 4 with respect to the base 2 and, consequently, the sliding movement of the movable top 5 with respect to the base 2 are restricted.

  On the other hand, when changing the relative position of the movable top 5 to the base 2, it is necessary to switch each slide switching mechanism 4B from the movement restricted state to the movement permitted state. 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 (see FIG. 7). Thereby, the link pressing body 4D1 presses the area near the base end of each link 4B5, 4B6 via the upper side link pressing rolling element 4D5 and the lower side link pressing rolling element 4D6, and these upper side link 4B5 and lower side As shown in FIGS. 8 and 9, the link 4 </ b> B <b> 6 is rotated around the link shaft 4 </ b> B <b> 7, and the upper rolling element 4 </ b> B <b> 3 provided at the tip 4 </ b> B <b> 51 of the upper link 4 </ b> B < While moving toward the opening side standing wall 21a, the lower side rolling element 4B4 provided at the distal end portion 4B61 of the lower side link 4B6 moves toward the rear side standing wall 22b of the lower side 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 movable top 5 together with the top movable support 4 with respect to the base 2, and change the relative position of the movable top 5 with respect to the base 2 along the extending direction of the base 2. be able to. In the present embodiment, since the rail grooves 21 and 22 are formed from one end to the other end of the base 2, the slide switching mechanism 4 </ b> B slides and moves the top plate movable support body 4 that is in a movement-permitted state. The top plate movable support 4 can be moved together with the movable top plate 5 to another adjacent base 2, or the top plate movable support 4 can be detached from the base 2 together with the movable top plate 5. In other words, the top plate movable support 4 once removed from the base 2 can be reattached to the base 2 using the rail grooves 21 and 22 by setting the slide switching mechanism 4B to the movement-permitted state. It is that.

  On the other hand, when each slide switching mechanism 4B is switched from the movement-permitted state to the movement-restricted state, an operation force for returning 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 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 to the pressing position shown in FIG. 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 top plate movable support body 4 moves in the direction of sinking due to the weight of the top plate movable support body 4 itself and the weight of the movable top plate 5, and each slide switching mechanism 4B moves upward as shown in FIG. The upper rolling element 4B3 is released from the contact state of the upper rolling body 4B3 with respect to the opening side standing wall 21a of the side rail groove 21, and the upper side contacting body 4B1 is brought into contact with or pressed against the opening side standing wall 21a of the upper rail groove 21; The contact state of the lower rolling element 4B4 with respect to the rear side standing wall 22b of the lower rail groove 22 is released, and the lower side contact body 4B2 is brought into contact with or pressed against the rear side standing wall 22b of the lower rail groove 22. It becomes a movement regulation state. Thereby, the sliding movement of the top plate movable support 4 with respect to the base 2 and by extension the movable top plate 5 is restricted.

  The top plate 5 supported by such a top plate movable support 4 is a support as shown in FIGS. 1, 3 and 4 (in FIG. 3, the top plate 5 is indicated by an imaginary line). 4, a top plate body 51 that can be turned horizontally around the turning shaft 5 a, a turning mechanism 52 for horizontally turning the top plate body 51, and a turning stopper disk 53 provided on the lower surface of the top plate body 51. It is provided. In the following description, in the state where the longitudinal direction of the top plate 5 is substantially orthogonal to the longitudinal direction of the base 2, the base 2 side of the top plate 5 is the rear, and the opposite side (the anti-base 2 side) is the front. To do.

  The top plate main body 51 has, for example, a substantially gourd shape in plan view (an elliptical shape with a central portion), and a relatively large size is applied in the present embodiment. A 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.
