Description

  The present invention relates to a desk system that can flexibly cope with various layout developments in an office or the like.

  Many of today's offices have introduced systems that can increase or decrease the number of desks so that they can flexibly respond to changes in the form of work and the number of people. In particular, since the number of offices that use the free address system is increasing in approximation, it is desirable that the seating position can be changed flexibly and that the work area for one-sided use and the work area for two-sided use can be configured appropriately. It is rare.

As such a system, for example, the one shown in Patent Document 1 can be cited. In this device, legs are attached to the back frame from the front and back to support the top board, and the position of the legs can be changed to accommodate various top board widths. U-shaped legs are used for all legs, and stable grounding is possible no matter which leg comes to the end. When adding the top plate surface, there is no specific indication, but it seems that it is possible to extend the back frame and attach a new leg to support the top plate.
Japanese Patent Application No. 2004-337452

  However, in Patent Document 1, the double-sided area cannot be separated into two independent single-sided desks, and all the legs are end legs, and the positions of the intermediate legs, that is, the top plates Because the lower limb space narrows in the depth direction at the adjacent boundary of, the inconvenience that the wagon can not be inserted at that position due to interference with the leg wings, the inconvenience that the worker's feet interfere with the leg and hinders work is inevitable It becomes. When all the legs are composed of intermediate legs with a narrow ground contact width, the end part needs a rigid end leg that can stand on its own, and when the intermediate leg changes from the intermediate leg to the end leg, Alternatively, it is essential to replace the leg when the end leg becomes an intermediate leg.

  The present invention has been made paying attention to such problems, and without changing the end leg and the intermediate leg one by one, the wagon or the worker's foot can be placed in a free position below the top board along the width direction. The realization of an insertable state allows easy implementation of a wide variety of layouts with a high degree of freedom, including lateral increase / decrease and changes between double-sided and single-sided use. The purpose is to provide a new desk system based on a completely new concept.

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

  In other words, the desk system of the present invention includes unit legs, unit beams, and unit top plates that are basic structural units, and by combining these basic structural units, a single-sided desk that secures strength as a structure. The double-sided desk or these horizontally connected desks can be selectively configured, and the change from any form to any other form can be performed through the addition or removal of the basic structural unit. . In addition, the single-sided desk referred to in this specification refers to a desk that allows the user to use the top plate surface only on one edge side of the top plate. The double-sided desk refers to a desk that allows the user to use the top plate. The desk of the form which can be simultaneously located in the edge part which opposes, and can use a top-plate surface in a facing state. Moreover, a horizontal connection desk means the desk of the form which connected desks in the top-plate width direction and expanded the top-plate surface.

  In this way, it is possible to effectively realize a wide variety of layouts including the selection of single-sided use or double-sided use as well as horizontal connection with the minimum number of parts required, and basically the layout can be changed. It is possible to easily cope with only by adding and removing common parts.

  In order to effectively realize a state in which a wagon or the like can be inserted at a free position below the top plate along the width direction, the unit leg includes a leg column having a grounding portion near the counter-use edge of the unit top plate and the leg. It is equipped with stays that extend substantially horizontally from the struts, and the front of these leg struts and the corners of the stays are used as the lower limb space where the wagon can be inserted together with the lower limb space under the top plate at the position where there is no unit leg. It is preferable that this is possible.

  In order to facilitate various developments such as lateral connection and face-to-face arrangement without losing the appearance of the system as much as possible, the unit beam functions as a strength member. It is desirable to construct a strong structure by connecting the unit top and the unit top plate between the unit legs.

  In this case, in order to properly realize the form of horizontal connection, the unit legs arranged in the middle can be configured to play a role as a connecting member that connects the left and right unit beams, or units arranged in the middle It is effective to configure the legs to support the edges of the left and right unit top plates at the same time.

  In order to respond flexibly by changing from a single desk to a linked desk or from a linked desk to a single desk, the engagement position between the unit beam and the unit leg is variable along the width direction. In addition to a mode in which the unit beams are half-engaged with the unit legs and connected, it is effective to adopt a mode in which one unit beam is deeply engaged with the unit legs.

  When the unit legs are arranged back to back to form a double-sided desk, it is desirable that the unit beams be overlapped back to back.

  In this case, in order to prevent the unit beam from interfering with the horizontal wiring function, the upper surface of the unit beam is set lower than the upper surface of the unit leg, and the unit legs are placed back to back via the unit beam. When a gap is formed between the counter-use edges of the unit top plates supported by these unit legs, a horizontal wiring space that leads to the gap is formed between the rear surface of the unit legs and the upper surface of the unit beam. It is convenient to do so.

  In order to develop more diverse layouts, it is preferable that the options can be detachably arranged while being supported directly or indirectly on the unit beam.

  A preferred embodiment of the option includes a panel such as a desktop panel, a curtain panel, or a partition panel.

  It is effective that the panel further includes an option mounting portion for mounting an optional member such as a shelf or a side panel.

  Similarly to the above, for more diverse layout development, the unit top plate includes a rectangular top plate and a modified top plate, and any top plate can be assembled to a common unit beam and unit leg. It is also effective.

  In order to stabilize the grounding state of the desk using the unit legs located at the ends, it is preferable that the end legs having a wide grounding width can be configured so that the unit legs are included in at least a part thereof, In particular, it is convenient that an end leg structure is provided as an auxiliary structural unit, and this end leg structure is detachably attached to the unit leg so that the end leg can be selectively configured. .

  Since the present invention has the configuration described above, it is possible to flexibly rearrange a single-sided desk, a double-sided desk, a connected desk, etc. by using only a few types of structural units, thereby enabling various layout settings or It is possible to provide an excellent desk system that can easily cope with a layout change.

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

  As shown in FIG. 1, the desk system according to this embodiment includes a unit leg 1 serving as a basic structural unit, a unit beam 2 that connects the rear portions of the unit leg 1, and a unit top plate 3. By combining the units, while ensuring the strength as a structure around the unit beam 2, the single-sided desk A shown in FIG. 2, the double-sided desk B shown in FIG. 3, and the horizontal sides shown in FIG. 4 and FIG. The connecting desks C and D, and the deformed desk E shown in FIG. 6 can be selectively configured. A layout change from any form to any other form can be easily and freely performed through addition and removal of basic structural units.

  More specifically, as shown in FIG. 1, the unit leg 1 has an inverted L shape in which a stay 12 is connected to the upper end portion of the leg support 11, and the leg side for engaging the unit beam 2 on the rear surface. A related portion 13 is provided. In the case of the present embodiment, the leg-side related portion 13 is a protrusion having a thickness substantially corresponding to the thickness of the leg support 11 of the unit leg 1.

  On the other hand, the unit beam 2 is a plate-shaped member having a width dimension substantially corresponding to the width dimension of the top plate 3, and is given strength as a strength member for ensuring the rigidity of the structure. Are provided with a beam-side related portion 21 that engages with the leg-side related portion 13 of the unit leg 1. In the case of this embodiment, this beam side related part 21 is a notch-shaped thing opened to the side end surface, and the thickness of this unit beam 2 and the protruding dimension of the protruding leg side related part 13 of the unit leg 1 Are roughly supported. The unit beam 2 may be a rod-like one as long as strength is ensured.

  The engagement position of the unit leg 1 with respect to the unit beam 2 is variable in the width direction depending on how deeply the leg side related portion 13 of the unit leg 1 and the beam side related portion 21 of the unit beam 2 are engaged. . That is, for example, when the unit leg 1 arranged in the center of FIG. 4 or the unit leg 1 shown in each part of FIG. A mode (hereinafter referred to as a semi-engaged state) in which the beam-side related portions 21 of the left and right unit beams 2 are half-engaged with the leg-side related portions 13 of the unit legs 1 can be taken. When the end surface 2a of the unit beam 2 and the side surface 1a of the unit leg 1 are substantially flush with each other in the unit leg 1 or the unit leg 1 arranged at the end as shown in FIG. It is also possible to adopt a mode (hereinafter referred to as a fully engaged state) in which 21 is deeply engaged so as to swallow the entire leg-side related portion 13.

  Further, since the width dimension of the unit top plate 3 substantially corresponds to the width dimension of the unit beam 2 as described above, when the unit beam 2 and the unit leg 1 are engaged in a half-engaged state, FIG. ), The side edge 3a of the unit top plate 3 placed thereon is supported on the stay 12 of the unit leg 1 in the region d of one half in the width direction. At this time, the other half The side edge of the adjacent unit top plate 3 is supported in the region d 'as shown in the figure, or the other half as shown in FIG. It can also be attached so as to partially cover the end panel 4d, etc., which is a structural unit (that is, the other half in the width direction of the unit leg 1 is inserted into the receiving portion 40 recessed in the inner surface of the end panel 4d). I am doing so. Alternatively, when the unit beam 2 and the unit leg 1 are engaged with each other in the fully engaged state, as shown in FIG. Since the edge portion is supported and the side end surface 3a of the unit top plate 3 and the side surface 1a of the unit leg 1 are substantially flush with each other, as shown in FIGS. The part panels 4a, 4f, 4b, and 4c can be attached without providing a receiving part or the like.

  On the other hand, when the double-sided desks B and D shown in FIG. 3 and FIG. 5 are configured, the unit beams 2 and 2 are overlapped with each other and the unit legs 1 are arranged back to back accordingly. In this case, the unit beams 2 and 2 are connected by an appropriate means. Then, the unit top plate 3 is supported between the stays 12 and 12 of the pair of left and right unit legs 1 at the back-to-back positions, and the double-sided desks B and D that can be used facing each other are constituted by the two unit top plates 3. Like to do. In the case of this embodiment, as shown in FIG. 5, the upper surface 2c of the unit beam 2 is set so as to be positioned lower than the upper surface 12b of the stay 12 of the unit leg 1 in the assembled state. When the gaps δ are formed between the counter-use edges 3c and 3c of the unit top plate 3 by placing them back to back via the unit beams 2 and supporting the unit top plate 3 on them, the unit legs 1 A horizontal wiring space δ ′ communicating with the gap δ is formed between the rear surface 1 c and the upper surface 2 c of the unit beam 2.

  In the above description, the unit top 3 includes the unit top 3 'having an irregular shape as shown in FIG. 6 in addition to the rectangular one, and the unit top 3' having a different shape is also the rectangular unit top. 3 is assembled to the same unit beam 2 and unit leg 1. Note that the desk in the figure also constitutes a double-sided desk according to the present invention in that it can be used face-to-face, and if both unit top plates 3 'are separated from this state, it can be made a single-sided desk and is vacant on the contrary. If the unit top plate 3 ′ having a different shape is further supplemented to the portion, a horizontal connection desk connected in the horizontal direction can be easily configured.

  Further, as shown in FIG. 5 and the like, when the unit top 3 is placed on the stay 12 of the unit leg 1, the grounding portion 11 a of the leg column 11 of the unit leg 1 is near the counter-use edge 3 c of the unit top 3. In addition, the stay 12 is configured to be relatively thin so that a sufficient distance L from the lower surface of the stay 12 to the floor F is secured. For this reason, a lower limb space S ′ into which the wagon W can be inserted together with the lower limb space S of the top plate 3 at a position where the unit leg 1 does not exist is formed in front of the corner portion between the leg support 11 and the stay 12. The space between the lower limbs S and S ′ is continuous in the lateral direction when the unit top 3 is laterally connected via the unit leg 1.

  By the way, as the above-mentioned auxiliary structural unit, in addition to the panel leg 4d shown in FIG. 5, only the U-shaped leg 4a and the leg blade 4f shown in FIG. 2, or the U-shaped leg as shown in FIG. The H leg 4b integrated with the half, the half-width panel leg 4c as shown in FIG. 4 and the like can be used. These auxiliary structural units also have unit legs 1 on their inner surfaces as shown in FIG. 7B when the unit legs 1 are in a semi-engaged state as shown in FIG. The unit 40 is provided so as to receive the region d ′ of the open half of the unit leg 1, in other words, to cover the half of the unit leg 1. What is necessary is just to attach to the leg 1. Alternatively, when the unit leg 1 is fully engaged in relation to the unit beam 2 shown in FIG. 2 to FIG. 4 etc., as shown in FIG. It is only necessary to attach to the outer surface 1a of the leg 1. In any case, the unit leg 1 of the present embodiment has a narrow ground contact width in which the leg support 11 contacts the back of the lower limb space S (S ′). As shown in (b) and (c), the auxiliary leg unit is added so as to include the unit leg 1 as a part, thereby constituting the end leg 20 having a wide ground contact width.

  FIG. 8 shows a state where the single-sided use area A is integrally formed at the end of the double-sided use area B. Since the end positions of these areas A and B are different, the end panel 4e is attached to each. I have to.

  Of course, although different from the gist of the present invention, it does not preclude partly adopting a dedicated end leg with a wide ground contact width instead of the unit leg 1 in the above.

  Furthermore, this embodiment utilizes the fact that the unit beam 2 is a strength member and supports the desktop panel 4 shown in FIG. 9 or FIG. Options such as the curtain panel 5 and the partition panel 6 are detachably arranged.

  First, FIG. 9 shows a state in which the desktop panel 4 is attached to a single-sided desk A. When such a desktop panel 4 is attached, the upper surface of the unit beam 1 has a width as shown in FIG. Vertical hole-shaped attachment portions 22 are provided at two locations in the direction. Then, by inserting a support rod 41 protruding from the lower surface of the desktop panel 4 into the mounting portion 22, the desktop panel 4 is supported on the unit beam 2 and arranged on the counter-use edge 3 c side of the unit top 3. To be able to. Since the unit beams 2 are overlapped in the double-sided use state of FIG. 3, if the desktop panel 4 is attached to the attachment portion 22 of any one of the unit beams 2, the horizontal wiring space is located above the other unit beam 2. δ ′ is effectively secured. Such a desktop panel 4 can be employed in the single-sided horizontal connection desk C shown in FIG. 4 or the double-sided horizontal connection desk D shown in FIG.

  FIG. 10 shows an example in which the curtain panel 5 is attached to a single-sided desk A and the partition panel 6 is attached so as to be stacked on the curtain panel 5. Is attached to a position covering the lower limb space S of the unit top 3 on the side opposite to the use edge 3c by an appropriate means. A groove-like option mounting portion 51 extending in the horizontal direction is further provided on the back surface near the upper edge. The partition panel 6 is provided above the curtain panel 6 under an appropriate connection structure to partition the work space. A groove extending horizontally on the front and back surfaces near the upper edge of the partition panel 6 is also provided. Further, an optional mounting portion 61 is provided. That is, the curtain panel 5 is directly attached to the unit beam 2 as an option, and the partition panel 6 is indirectly attached to the unit beam 2 as an option via the curtain panel 5 and is further provided on these panels 5 and 6. The side panel 7 is arranged as an option member in a state of being orthogonal to the curtain panel 5 as shown in FIG. 11 using the option mounting portions 51 and 61, or a storage shelf as an option member on the front surface of the partition panel 6 8 is arranged so that it can be developed in various ways. Further, the option to be directly or indirectly attached to the unit beam 2 is not limited to the panel, and other types of options such as a telephone stand, a light, and a shelf can be attached in an appropriate manner.

  In particular, in FIG. 11, a complicated system desk is configured, but basically the basic structural units such as the unit beam 2, the unit leg 1, and the unit top plate 3 ′ (in this case, an irregular shape) are combined, Only auxiliary unit elements and the like are added as necessary.

  As shown in FIG. 12, when the double-sided desks B are laterally connected, as shown in FIG. 7A, the side edge portions 3a of the adjacent unit top plates 3 are respectively connected to the unit legs 1. Since it is in a state of being supported by the regions d and d 'of the half halves in the width direction on the stay 12, one of the pair of unit top plates 3 constituting the double-sided desk B located at the center can be easily hollowed out. The layout having the open space SP can be easily changed. The end panel 4e may be attached to the open space SP as in FIG. Then, it is possible to easily develop a layout having more variations, such as setting a copy corner in a part of the office space using the open space SP.

  As described above, the desk system of this embodiment includes the unit legs 1, the unit beams 2, and the unit top plate 3 that are basic structural units, and combines these basic structural units to increase the strength as a structure. 2, a single-sided desk A as shown in FIG. 2, a double-sided desk B as shown in FIG. 3, or these horizontally connected desks C and D as shown in FIGS. 4 and 5 can be selectively configured. In addition, the change from any form to any other form can be made through the addition or removal of basic structural units such as unit legs 1, unit beams 2, unit top plate 3, etc. is there.

  In this way, it is possible to effectively realize a wide variety of layouts that combine single-sided use, double-sided use, and horizontal connection with the minimum necessary number of parts, and are also basically common parts for changing the layout. It is possible to easily cope with only the addition and removal of the basic structural unit.

  The unit leg 1 includes a leg column 11 having a grounding portion 11a in the vicinity of the counter-use edge 3c of the unit top plate 3 and a stay 12 extending substantially horizontally from the leg column 11. Since the front of the corner of the stay 12 can be used as the lower limb space S ′ in which the wagon W can be inserted together with the lower limb space S below the top plate at the position where the unit leg 1 does not exist, The continuity of the lower limb spaces S and S ′ is ensured even at the boundary of the top 3, that is, at the position where the unit leg 1 exists as an intermediate leg, and it becomes possible to effectively cope with the free address system and the like. .

  In particular, the unit beam 2 is a plate-like member that functions as a strength member. The unit beam 2 is connected between the rear portions of the pair of unit legs 1 and 1, and the unit top plate 3 is connected between the unit legs 1 and 1. By constructing a strong structure, the unit beam 2 is located at such a position, so that the unit beam 2 can secure rigidity enough to function as a strength member. The influence on the appearance can be reduced. By constructing the structure with the unit beam 2 as a main body in this way, it is possible to effectively realize development such as lateral connection and facing arrangement on a unit beam basis, and further, panels 4, 5, 6 and options. It can also be effectively used as a place for supporting the members 7, 8 and the like.

  Moreover, in the form of horizontal connection, since the unit leg 1 arrange | positioned in the middle plays the role as a connection member which connects the left and right unit beams 2 and 2, unit beams 2 and 2 are connected. This eliminates the need for a special connecting member.

  Alternatively, in the laterally connected form, the unit legs 1 arranged in the middle support the edges of the left and right unit top plates 3 at the same time, so when the unit legs 1 are arranged in the middle, It can be effectively avoided that the legs double and become bulky at the boundary between the plates 3 and 3.

  In addition to the mode in which the engagement position between the unit beam 2 and the unit leg 1 is variable along the width direction and the two unit beams 2 and 2 are engaged with the unit leg 1 in half and connected, one unit Since it is possible to adopt a mode in which the beam 2 is deeply engaged with the unit leg 1, the unit beam can be appropriately handled when the unit leg 1 is located in the middle of the horizontal connection desk, or when the unit leg is located at the end. 2 can be flexibly dealt with, for example, when there is a situation where the end surface 2c of 2 and the outer surface 1c of the unit leg 1 must be aligned. As shown in FIG. Change to a simple connection desk C, or a change opposite to this, or a change from a series of double-sided desk B as shown in FIG. 3 to a double-sided connection desk D as shown in FIG. 5, or a change opposite to this Etc. can also be easily performed.

  Further, when the unit legs 1 and 1 are arranged back to back to form the double-sided desk B shown in FIG. 3, the unit beams 2 and 2 are overlapped back to back, so that they function as strength members. Although the unit beams 2 overlap each other, the position of the unit beams 2 is an anti-use edge, so there is little influence on the lower limb space S. Rather, the unit beams 2 and 2 are not only effective in securing strength. Therefore, the desk can be easily separated from the double-sided use shown in FIG. 3 to the single-sided use shown in FIG. 2.

  Further, as shown in FIG. 5, the upper surface 2c of the unit beam 2 is set at a lower position than the upper surface 12b of the unit leg 1, and the unit legs 1, 1 are arranged back to back through the unit beam 2, When the gap δ is formed between the counter-use edges 3c and 3c of the unit top plate 3 supported by the unit legs 1, the gap is formed between the rear surface 1c of the unit leg 1 and the upper surface 2c of the unit beam 2. Since the horizontal wiring space δ ′ leading to δ is formed, the horizontal wiring function of the connecting desk can be effectively ensured even if such a unit beam 2 exists.

  In addition to the above, this embodiment is configured so that options such as the desktop panel 4, the curtain panel 5, the partition panel 6 and the like can be detachably arranged in a state of being directly or indirectly supported by the unit beam 2. This is an example in which one of the concepts of the present invention in which the layout is developed based on the unit beam 2 can be effectively used.

  In particular, the relatively heavy panels such as desktop panels, curtain panels, and partition panels can be used as options because the unit beam 2 is a strength member and can be the structural base. is there. Of course, it goes without saying that options other than the panel can be attached to the unit beam 2.

  Further, the panel 5, 6 is further provided with optional attachment portions 51, 61, and the optional members such as the side panel 7 and the shelf 8 can be attached to these optional attachment portions 51, 61. It can be said that the structure can be developed using the strength of. In this case as well, other appropriate modes can be adopted for the option mounting portion, and the option member attached to this is not limited to the above.

  The unit top plate 3 of the present embodiment includes a rectangular top plate 3 and a modified top plate 3 ′, and these top plates 3 and 3 ′ are assembled to the common unit beam 2 and unit leg 1. Therefore, if only the top plate 3 is changed, a rectangular desk as shown in FIG. 2 and a deformed desk as shown in FIGS. 6 and 11 can be easily configured. Thus, since the support structure is common, a mode in which the rectangular top plate 3 and the deformed top plate 3 ′ are connected as shown in FIG. 13 can be easily realized.

  In addition, the end leg 20 having a wide ground contact width can be configured so as to include the unit leg 1 located at the end in at least a part thereof, so that it is not necessary to replace the intermediate leg with the end leg. While easily switching the mode in which the unit leg 1 functions as an intermediate leg or as an end leg, securing of the lower limb space S and stabilization of the grounding state of the desk can be achieved.

  In this case, various types of legs 4a to 4d are provided as auxiliary structural units, and the end legs 40 are selectively configured by detachably attaching these leg 4a to 4d end leg structures to the unit leg 1. Therefore, the function of the unit leg 1 can be easily switched from the intermediate leg to the end leg and from the end leg to the intermediate leg only by attaching and detaching such an auxiliary component unit when increasing and decreasing. .

  The specific configuration of each part is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. The concept of the desk of the present invention naturally includes what is called a table.
