Description

  The present invention relates to a desk system suitably applied to an office or the like that employs a free address system.

  In recent offices, a so-called free address system is often adopted in which workers do not have their own seats, but sit at appropriate places on a large desk and work. In this case, in order to prevent the feet from interfering with the intermediate leg and the wagon etc. can be inserted into the necessary place under the top plate, the intermediate leg is grounded only on the counter-use edge side to open the lower space on the use edge side, Using the end legs with a ground contact width in the front-rear direction at the end, the top plate is supported on the horizontal part of these intermediate legs and end legs to ensure desk independence and continuity of the leg space What you do is known. In addition, a large number of desk systems that have a pair of top plates that can be used face-to-face on the horizontal part along the depth direction are also used in a relatively large amount. In general, the structure is integrally supported by a connecting member that connects the two.

As a function of such a desk system, a part of which an open space is formed at a position where a part of the top plate is removed and the open space can be used as a copy corner or the like is considered in part.
Japanese Patent Laid-Open No. 06-269321

  However, in the free address type desk system in which the lower limb space is continuous as described above, the pair of top plates in the facing direction are balanced on the connecting member via the intermediate legs, so when one top plate is removed, That balance is lost.

  And since the intermediate leg is not grounded to the use edge side, the use edge side of the top plate at the facing position of the open space sinks, and the tip of the intermediate leg adjacent to the open space is placed on the site. The phenomenon of rising easily occurs, the installation state and use state of the entire desk become incomplete, and the level of the top plate and the continuity of the surface once decrease, and the appearance is easily damaged.

  The present invention has been made paying attention to such problems, and when a part of the top plate is removed as one of the layouts in a free address type desk system etc., the installation state and use of the entire desk The purpose is to realize a new structure that is useful in maintaining the state appropriately with the appearance.

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

  That is, the desk system of the present invention includes an intermediate leg that is grounded on the opposite side of the use and has a horizontal portion extending toward the use side, and an end leg that is grounded on at least two points from the opposite side to the use side. A connecting member that connects the intermediate legs or between the intermediate legs and the end legs, and can be attached / detached between the horizontal parts of the adjacent intermediate legs or between the horizontal parts of the intermediate legs and the end legs. A plurality of top plates that are connected to each other in the width direction using the horizontal part and arranged so that they can face each other in the depth direction. The connecting member is configured to be integrally supported via the legs.

  Then, when an open space is formed by removing a part of the top plate, a weight adding portion that compensates for at least a part of the weight replacing the top plate is provided in the vicinity of the open space. And

  If comprised in this way, it can suppress that the gravity center position of a pair of top plate in a facing position moves by removing one top plate, through the weight addition part provided in the open space vicinity, Therefore Open Even if the space is formed, it is possible to prevent the weight balance from being largely lost, and to keep the desk system installed and used properly.

  In order to use the configuration of the weight adding portion at the same time as a countermeasure against sinking of the top plate, it is effective that the weight adding portion is an auxiliary leg attached later to an intermediate leg adjacent to the open space.

  In order to appropriately increase / decrease the weight of the auxiliary leg according to the situation without impairing the appearance, the auxiliary leg further includes a hollow part for loading a balance weight therein, and an opening / closing part for opening / closing the hollow part. It is desirable that

  Preferred embodiments of the present invention other than those described above include the following.

  The aspect in which the weight addition part is provided with the hollow part for loading a balance weight in the inside of a top plate, and the opening-and-closing part which opens and closes this hollow part.

  Alternatively, when the connecting member is in the shape of a back plate, the weight adding portion includes a hollow portion for loading a balance weight inside the connecting member and an opening / closing portion for opening and closing the hollow portion. Aspect.

  Since the present invention has the configuration described above, the desk system is supported by the connecting member via the intermediate leg in a state where the top plate is detachable and the pair of top plates are arranged facing each other as in the free address type. As one of the layouts, the weight balance of the top board will be lost when a part of the top board is removed, and a weight addition part is provided in the vicinity of the open space formed at the position where the top board is removed. Providing a highly practical desk system that makes the original layout change function truly effective while ensuring the proper appearance, installation state, and usage state of the entire desk. It becomes possible.

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

  As shown in FIG. 1, the desk system of this embodiment includes an end leg 1 and an intermediate leg 2, and supports a plurality of top plates 3 along the width direction on these legs 1 and 2, and a depth. A large desk is constructed by arranging the top plates 3 on each pair in a state where they can be used facing each other.

  The intermediate leg 2 is a leg column 21 that is an upright portion that contacts the counter-use edge 3 b side of the top plate 3, and a stay 22 that is a horizontal portion that extends from the upper end portion of the leg column 21 toward the use edge 3 a side of the top plate 3. In this embodiment, the intermediate leg 2 has an inverted L shape. Here, the use edge 3a side means an edge part on the side close to the user seated on the top board 3, and the counter use edge 3b side means an edge part on the side far from the user seated on the top board 3. Say. When the top plates 3 and 3 are arranged facing each other, both edges in the depth direction of the entire desk system become the use edges 3a, and the counter use edges 3b and 3b face each other in the center.

  As shown in FIGS. 2 and 3, the stay 22 includes movable claws 22b and 22c that are protruded upward from the top plate support surface 22a set on the upper surface of the stay 22 and bent backward, and both movable claws 22b, A tongue-like anchor portion 22d protruding upward from between 22c is provided. The movable claws 22b and 22c can be integrally actuated in the depth direction of the stay 22 by a drive mechanism 23 configured in the stay 22, and are hook holes provided on the lower surface near the side edge 3c of the top plate 3 shown in FIG. 31 and 32 are simultaneously engaged. The anchor portion 22d is inserted into a slit 33 provided at a corresponding position of the top plate 3, and positions the top plate 3 in the depth direction. Therefore, the movable claws 22 b and 22 c can fix the top plate 3 to the stay 22 in the depth direction and the thickness direction without dragging the top plate 3.

  As shown in FIGS. 2 and 3, the leg struts 21 constituting the intermediate leg 2 are also provided between upper and lower movable claws 21b and 21c that protrude rearward from the rear surface 21a and bend downward, and both movable claws 21b and 21c. A tongue-shaped anchor portion 21d that protrudes rearward from the upper side and an anchor portion 21e that protrudes rearward from above the upper movable claw 21b and bends upward are provided. The movable claws 21b and 21c can be integrally actuated in the vertical direction of the leg column 21 by a drive mechanism 25 configured in the leg column 21, and the front surface in the vicinity of the side edge 4c of the back plate 4 as a connecting member shown in FIG. Are simultaneously engaged with the hook holes 41,. The anchor portions 21d and 21e are inserted into slits 43 and 44 provided at corresponding positions of the back plate 4 to position the back plate 4 in the vertical direction. Therefore, the movable claws 21 b and 21 c can fix the back plate 4 to the leg column 21 in the vertical direction and the thickness direction without dragging the back plate 4.

  Each of the movable claws 22b, 22c, 21b, 21c and the anchor portions 22d, 21d, 21e are provided in pairs in the width direction of the desk, and hook holes 31, 32, 41 of the corresponding top plate 3 and back plate 4 are provided. 42 and slits 33, 43, 44 are also provided for each pair. When the left and right top plates 3, 3 are supported by the common intermediate leg 2, the half-width region of the top plate support surface 22 a of the stay 22 supports the side edges 3 c of the left and right top plates 3. . The same applies to the back plate 4. The intermediate legs 2 and 2 at the facing positions are attached back to back from a front and rear direction to a common back plate 4 that is a connecting member.

  In this way, the intermediate leg 2 is engaged with the left and right top plates 3 and 3 and is also engaged with the left and right back plates 4 and 4, and the pair of intermediate legs 2 and 2 are also a common back plate in the facing direction. 4, the back plate 4, the intermediate leg 2, and the top plate 3 are integrally connected as shown in FIG. 1 to constitute a large desk.

  The end leg 1 shown in FIG. 1 has a panel shape, and a specific structure will be described later. However, the end leg 1 has a structure that is detachably engaged with the top plate 3 and the back plate 4, and is omitted in FIG. However, they are grounded at two locations on the counter edge 3b side and the counter edge 3a side. In other words, the desk is secured by the end legs 1, and the lower limb space S of the top board 3 is continuous in the width direction via the lower space T of the stay 22 of the intermediate leg 2, so that the seated person can It is possible to sit at an arbitrary place without interfering with the intermediate leg 2, and a wagon or the like can be inserted at an arbitrary position without interfering with the intermediate leg 2.

  And since the top plate 3 is detachable with respect to the end leg 1 and the intermediate leg 2, and the end leg 1 is also detachable with respect to the back plate 4, as shown in FIGS. A cutout layout in which a part of the top plate 3 is removed together with the legs 1 can be realized.

  In this case, a part of the intermediate legs 2 (2V) is newly positioned at the end in the top plate width direction, and an open space OP is formed at a site where the side top plate 3 is removed. The leg 2 (2V) is grounded only on the counter-use edge 3b side of the top board 3, and the lower space T on the use edge 3a side is opened, so that the leg space S of the top board 3 is on the open space OP side. It appears in a miscellaneous state (shown on the arrow X side in FIG. 4), leading to a loss of the appearance of the desk, and the open space OP is not clearly partitioned, so that the usability is reduced. Further, when the upper load W1 acts on the stay 22 of the intermediate leg 2 (2V), the intermediate leg 2 is grounded only on the side opposite to the use edge 3b of the top board 3, so that the use edge 3a side of the top board 3 sinks. Easily unstable.

  Furthermore, in the state of FIG. 1 before removing the top plate 3, the load on the pair of top plates 3, 3 in the facing direction was balanced on the back plate 4, which is a connecting member, via the intermediate legs 2. If one top plate 3 is removed as shown in FIG. 4, the balance will be lost. And since the intermediate leg 2 is not grounded to the use edge 3a side, the use edge 3a side of the top plate 3 (3U) at the facing position of the open space OP sinks as shown by an arrow Y1 in the figure, Along with this, the phenomenon that the tip of the stay 22 of the intermediate leg 2 (2V) adjacent to the open space OP rises together with the adjacent top plate 3 as shown by the arrow Y2 in the figure is likely to occur, and the proper installation / use state In addition to the damage, the level and surface of the top plate are reduced, and the continuity is also lowered, which makes the appearance worse.

  Therefore, in the present embodiment, as shown in FIG. 5, the cover leg C serving as an auxiliary leg serving as an auxiliary leg that functions as a weight addition unit as well as a blindfold function and a top plate support function as compared with the intermediate leg 2 (2V) shown in FIG. 4. Can be attached. As shown in FIG. 7, the cover leg C includes an inner panel 5, an outer panel 6, and a grounding portion 7.

  As shown in FIG. 6 and the like, the inner panel 5 has front and rear vertical frames 52 and 53, an upper frame 54, and a lower frame 55 formed on four sides of the face plate 51, and protrudes upward on the upper surface of the upper frame 54. Fixed pawls 54a bent backward are provided at two positions in the front and rear. These fixing claws 54a are engaged with each other in the depth direction and the vertical direction by being inserted from below into a hook hole 22e provided at a position corresponding to the lower surface of the stay 22 and sliding backward. The fixing claw 54a functions as a first engaging portion that fixes the upper edge of the inner panel 5 to the stay 22. The hook holes 22e of the stay 22 are provided in pairs in the width direction. In addition, hook holes 5x and 2x are formed on the outward surface of the vertical frame 52 of the inner panel 5 and the outer surface of the leg strut 21 constituting the intermediate leg 2 in pairs when the inner panel 5 shown in FIG. The rear surface 53a of the vertical frame 53 of the inner panel 5 is disposed so as to be in close contact with the front surface 21a of the leg column 21.

  On the other hand, the outer panel 6 includes a top plate 62 and a front plate 63 on at least two sides of the face plate 61 that functions as a side plate in the attached state, and is provided with longitudinal reinforcing portions 64 and 65 in the vicinity of both front and rear edges on the inner surface of the face plate 61. Therefore, in these vertical reinforcing portions 64 and 65, downward claws 6x are cut and raised at corresponding portions of the hook holes 5x and 2x forming the above-mentioned set. The top plate 62 has an angled shape, and when the outer panel 6 is mounted, the stay 22 is exposed when the top plate 62 is removed while inserting the downward claws 6x into the hook holes 5x and 2x. The half of the inner panel 5 is pushed down so as to cover the position over the movable claws 22b, 22c and the anchor 22d so that the inner panel 5 and a part of the intermediate leg 2 are received in the flat inner space of the outer panel 6. I have to. The downward claws 6x function as a second engagement portion that indirectly fixes the inner panel 5 and the leg support 22. As a result, as shown in FIGS. 7 to 5, the top surface of the top plate 62 is substantially continuous with the top surface of the top plate 33, and the front and back positions of the front surface of the front plate 63 substantially coincide with the use edge 3 a of the top plate 3. The face plate 61 is attached in a state of being in close contact with the vertical frame 52 of the inner panel 5 and the outer surface of the leg strut 22 of the intermediate leg 2 via the reinforcing portions 64 and 65 so as to constitute a new end leg 1A. I have to. The front plate 63 of the outer panel 6 is set so that the protruding amount from the face plate 61 is larger than the reinforcing portions 64 and 65, and when the top plate 62 closes one half of the stay 22, the front plate 63 is the vertical frame 52 of the inner panel 5. It is arranged in a position to block the front of the.

  In the above, the face plate 51 of the inner panel 5 constituting the cover leg C is provided with opposing pieces 51a and 51b protruding in an up and down angle as shown in FIG. 6, and between these opposing pieces 51a and 51b. In addition, the balance weight 8 can be loaded by the so-called Kendon system as shown in FIGS. And by attaching the outer panel 6 from the top, the flat hollow part A is formed between the face plates 51 and 61, and the outer panel 6 comes to play a role as an opening / closing part that opens and closes the hollow part A. ing. The balance weight 8 has a thin plate shape as shown in FIG. 6, and a predetermined number of balance weights 8 can be loaded in the hollow portion A in a stacked state.

  The grounding portion 7 is configured by attaching an adjuster 72 via a nut 71 to the use edge 3a side of the lower frame 55 of the inner panel 5 so that the inner panel 5 is suspended from the lower surface of the stay 22 via a fixing claw 54a. By adjusting the adjuster 72 in the attached state, the inner panel 5 can be tightly interposed between the floor and the stay 22. Although not shown in FIGS. 1 to 4 and the like, an adjuster 20 is attached to the lower end side of the leg support 21 of the intermediate leg 2 as shown in FIG.

  In this embodiment, the end leg 1 shown in FIG. 1 or the like is a new end of FIG. 5 configured by attaching a cover leg C composed of an inner panel 5, an outer panel 6 and a grounding portion 7 to the intermediate leg 2. It has the same structure as the leg 1A. Accordingly, if the cover leg C is removed, the intermediate leg 2 is exposed together with the top plate support surface 22a of the stay 22 as shown in FIG. 6, and the top plate 3 can be further extended outwardly. It has become.

  As described above, the desk system according to the present embodiment includes the intermediate leg 2 that is grounded on the counter-use edge 3b side and extends the stay 22 that is a horizontal portion on the counter-use edge 3a side, and the counter-edge from the counter-use edge 3b side. An end leg 1 that is grounded at two locations toward the 3a side, a back plate 4 that is a connecting member that connects the adjacent intermediate legs 2 and 2 or between the intermediate leg 2 and the end leg 1, and an adjacent intermediate leg 2 And the top plate 3 that is detachably placed across the stay 22 of the intermediate leg 2 and the stay 22 of the intermediate leg included in the end leg 1. A plurality of top plates 3 are connected in the width direction and arranged so as to be able to face each other in the depth direction, and the load of the pair of top plates 3, 3 at the facing position is a connecting member via the intermediate leg 2. The plate 4 is configured to be integrally supported.

  Then, when a part of the top plate 3 is removed and the open space OP is formed as shown in FIG. 4, as a weight adding portion for compensating at least a part of the weight replacing the top plate 3, FIG. The cover leg C shown in FIG. 7 is provided in the vicinity of the open space OP.

  For this reason, in the state before removing the top plate 3, as shown in FIG. 9A, the load Wa of the pair of top plates 3, 3 in the facing direction is a back plate 4 which is a connecting member via the intermediate leg 2. Even if the balance is lost and the balance is lost by removing one of the top plates 3 as shown in FIG. Therefore, the balance with the center of gravity m of the top plate 3 at the facing position can be achieved. For this reason, even if the open space OP is formed, the intermediate leg 2 can be prevented from being tilted together with the top plate 3 due to the weight balance being largely lost, and the installation state and the use state of the desk system can be appropriately maintained. As a result, the level of the top plate 3 and the surface can be prevented from being lowered once and the continuity can be prevented, and the appearance of the entire desk can be effectively adjusted.

  In addition, since the weight addition portion has the cover leg structure as described above, the weight of the cover leg C itself can be used, and the use when the upper load W1 as shown in FIG. This also functions as a means for appropriately preventing the sinking on the edge 3a side, and contributes to further stabilizing the installation state and use state of the desk.

  And since the cover leg C is provided with the hollow part A which loads the balance weight 8 inside, and the outer panel 6 which is an opening-and-closing part which opens and closes this hollow part A, the balance weight 8 of the balance weight 8 is not impaired. Through simple attachment and detachment, the weight of the cover leg C can be appropriately increased or decreased depending on the situation.

  Furthermore, in the above embodiment, when the plurality of top plates 3 are connected in the width direction, a part of the top plates 3 are removed together with the end legs 1 to form the open space OP shown in FIG. In addition, the cover leg C is attached to the intermediate leg 2 (2V) adjacent to the open space OP so as to conceal it, but the desk system of the present embodiment has a plurality of top plates 3 connected in the width direction. In the state shown in FIG. 1, when a part of the top plate 3 is removed from between the left and right top plates 3 to form the open space OP2 as shown in FIG. 8, the cover leg C is adjacent to the open space OP2. You may make it attach to the intermediate leg 2 (2W) of the both sides to perform. In this way, appropriate weight compensation can be performed on the intermediate leg 2 (2W) located on both sides of the open space OP2, and the virtual weight Wx is used for the open space OP2 in which the top board 3 was located. Positioning at the center, it becomes possible to properly perform the weight balance with the weight Wa of the opposing top plate 3.

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

  For example, in FIGS. 4 and 8, a hollow portion A2 as shown in FIG. 10 is formed on the lower surface 3d side of the top plate 3 located on the side of the open space OP so that the balance weight 108 can be loaded. Even if the weight adding portion D of the present invention is configured such that A2 can be opened and closed by the opening and closing portion 106 such as a cover, the inclination of the intermediate leg 2 (2V, 2W) adjacent to the open space OP can be prevented. It is desirable that the weight adding portion D is configured in the vicinity of the side edge 3c of the top plate 3, that is, a position close to the intermediate leg 2.

  Alternatively, in FIG. 4 and FIG. 8, a hollow portion A3 as shown in FIG. 11 is formed on the front surface 4d side of the back plate 4 which is a connecting member located in the back of the open space OP so that the balance weight 208 can be loaded. The same effect as that of the above-described embodiment can be achieved by the weight adding portion E of the present invention in which the hollow portion A3 can be opened and closed by the opening and closing portion 206 such as a cover. The weight adding portion E may be configured in the vicinity of the side edge 4c of the back plate 4, that is, in a position close to the intermediate leg 2. A balance can also be achieved.

  In addition, the intermediate leg 2 of the above embodiment has an inverted L shape and is connected back to back in the depth direction via the back plate 4, but the top plates 3 and 3 are placed in a pair. It may be in the form of a letter.

  Furthermore, for example, when adopting a layout in which one of the pair of top plates 3, 3 arranged so as to be used facing each other is removed and the top plate 3 is continuous in the width direction only on one side, the intermediate leg 2 may be Since it is only grounded on the side of the use edge 3b, the entire top plate is supported only by the left and right end legs 1, and the sinking of the top plate 3 is more severe as the position is closer to the center in the width direction. Tends to be bent. In such a case, if the inner panel 5 is disposed below the stay 22 below the top plate 3, the top plate 3 positioned from the center is appropriately supported, and the installation state and use state are optimized. It can also be used to plan. In this case, a panel having a slightly smaller height than the outer panel may be attached to the inner panel to close the portion that becomes the hollow portion.

  In addition, the present invention is applied to a desk in a situation where it is difficult to say that the lower limb space is always continuous if the leg can be tilted by removing the top plate. The same operational effects can be achieved.

  Other configurations can be variously modified without departing from the spirit of the present invention.
