Description

  The present invention relates to a desk system that efficiently constitutes a large top plate and can easily cope with increase / decrease, reduction, connection, separation, and the like.

  In a recent desk system, when a large desk is constructed by connecting top plates, end legs having a ground contact width substantially corresponding to the depth dimension of the top plate are used at the end portions, and the top plate is used at the intermediate portion. It is customary to use an intermediate leg having a ground contact width narrower than the depth dimension, and the intermediate leg is supported by a pair of adjacent top plates at the same time, thereby avoiding the bulkiness of the leg. Both the stabilization of the support state and the securing of the lower limb space in the middle part are achieved, and the number of legs is also minimized.

  By the way, when such a large desk increases or decreases, it is usual that the desk is dismantled once and the work is usually performed. At that time, the part which was the end leg is replaced with an intermediate leg, and is newly positioned at the outer end. The end leg is attached to the part to be done. For this reason, there is a problem that a great deal of labor and time are required to change the layout.

  On the other hand, the thing which added the end leg and the top plate to the outer side of the end leg as it is is considered. For example, the one disclosed in Patent Document 1 connects end legs and sleeves to a back frame used as a strength member, and connects these end legs, between sleeves, or between end legs and sleeves with a top plate. The legs and sleeves can be repositioned within the dimensions of the back frame.Although there is no explicit description for the addition of a top plate or legs, the back frame is extended to It seems that it can be supported by adding legs and a top plate.

Moreover, in the thing of patent document 2, in order to connect desks, the end legs located in an edge part are bonded together, and it adds to a link, and a reduction is reduced by separating the end legs. Trying to get.

  However, since the end legs of Patent Document 1 are all U-shaped with a wide ground contact width, especially when the free address system is adopted, when the end legs are positioned in the middle part, There is a problem that the insertion of the wagon at a free position along the width direction and the securing of the foot space are easily hindered. Although the thing of the patent document can change the position of a leg, since there is a limit in the range which can support a top plate appropriately, it cannot be said that the continuity of lower limb space is fully secured yet. Further, even when it is desired to reduce the number of connecting desks, it is difficult to say that this structure can effectively cope with the increase / decrease sequence because the top plate and the back frame are not clearly separated at a predetermined position.

  On the other hand, since the thing of patent document 2 is the structure which leg | legs superpose | polymerize also in an intermediate part and an edge part, in addition to a cause of a cost increase with a large number of parts, a leg space is also narrowed by the bulk of a leg. It will be a thing. In addition, it is connected to independent desks when you simply want to add more top plates, and it is separated into independent desks when you simply want to reduce the number of top plates. It is hard to say that a reasonable increase / decrease series taking into consideration is being carried out.

  The present invention has been made paying attention to these problems, and eliminates the complexity of replacing the end legs and intermediate legs due to layout changes, etc., and can easily secure the leg space. The purpose is to provide a system.

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

That is, in the desk system of the present invention, when a large desk is configured by connecting the top plates, the adjacent top plates are supported by half halves of the common intermediate leg, and the intermediate legs that are positioned at the end portions are supported. On the other hand, the end leg can be configured by detachably adding an end member so as to cover the opened half.
With this configuration, even if the leg at the end is located in the middle due to the increase / decrease sequence, or the leg located at the middle is located at the end, Since any form of the end leg and the intermediate leg can be taken only by attaching and detaching the part member, it is unnecessary to replace the intermediate leg and the end leg one by one. In addition, since the intermediate leg can simultaneously support the adjacent top plates, the legs do not overlap and become bulky, and the lower limb space can be widened along the width direction. Furthermore, although the intermediate leg and the end member overlap at the end, the end member is attached so as to cover a part of the intermediate leg, so that the bulk is suppressed as much as possible than the sum of the respective width dimensions. On the other hand, the function of the end legs with a wide contact width can be effectively exhibited. And, in the above, if it is constructed so that the ground contact width of the intermediate leg with a narrow ground contact width can be widened by attaching the end member to form an end leg, securing the lower limb space in the depth direction at the intermediate part and It is possible to appropriately balance the stabilization of the ground contact state at the end.

  In order to appropriately add the top plate, the end member is removed from the end leg without disassembling the top plate, the intermediate leg and other structural parts constituting the existing desk, and the end member is removed. By supporting the top plate to be added to the half of the intermediate leg that has been attached, and adding the end member previously removed to the intermediate leg that will be newly located at the end, the end is added. It is desirable to be able to configure the legs.

  In order to properly reduce the top plate, the required intermediate legs and end legs together with the top plate are not accompanied by dismantling of the desk top plate, intermediate legs and other structural parts left by the reduction. The end leg is constructed by adding the end member attached to the end leg that has been removed first to the half half that is removed and newly opened in the intermediate leg that will be located at the end. It is desirable to get it.

  In order to properly connect the desks, the end members are removed from the end legs without disassembling the existing top plate, intermediate legs and other structural parts at each desk to be connected. It is desirable that the desks can be connected to each other by installing a new top plate on one half of the intermediate leg that will be located at the end of the base.

  In order to properly separate the desks, the top plate and other necessary members are removed without disassembling the top plate, intermediate legs and other structural parts of the desk portion that should be left by separation, and each separated desk is separated. It is desirable that the end leg can be constructed by adding an end member to one half of the intermediate leg that will be newly positioned at the end.

  As a preferred embodiment of the end member, a frame structure having at least left and right side frames and an upper frame is formed, and the upper frame or its peripheral part is covered with one half of the intermediate leg, and the side frame is attached to the intermediate leg. There are those which are attached to the intermediate leg so as to be positioned outside the leg support.

  Alternatively, another preferable embodiment of the end member is a panel leg-like shape in which a face material is attached to the outside of a frame structure including at least left and right side frames and an upper frame, and the inside is recessed. The upper frame or its peripheral part is placed on one half of the intermediate leg while receiving a part of the intermediate leg in the recess, and the side frame is positioned outside the leg support of the intermediate leg so that it can be attached to the intermediate leg. The thing that is.

  As the structure of the structure that can easily cope with the increase / decrease station and the connection and separation of the desk, the intermediate leg includes a leg column and a stay that extends substantially horizontally to the upper end side of the leg column and supports the top plate. In this case, a beam is installed between the stays so that the intermediate legs are detachably connected. In this case, in order to secure the space for the lower limbs, it is desirable that the leg support is grounded on the side of the top plate that is not used.

  In addition, a desk system according to another configuration of the present invention for achieving the same object is configured to be able to configure a large desk with a series of top plates, and an adjacent top plate is used as an intermediate leg. The common leg is supported, and the common leg is deformed to be used as an end leg.

  If comprised in this way, the form of a common leg will be changed even if the leg which was located in the end by the increase / decrease series will be located in the middle, or the leg located in the middle will be located in the end. Since only the end leg and the intermediate leg can be taken, it becomes unnecessary to replace the intermediate leg and the end leg one by one. Moreover, since the common leg can support the adjacent top plates at the same time, it is possible to avoid the inconvenience that the legs overlap and become bulky, and to make the leg space as wide as possible. Furthermore, since the common legs do not overlap at the end portions, the bulkiness here can be effectively avoided. Also in this case, if the deformation is to change the form of the intermediate leg with a narrow ground contact width and the end leg with a wide ground contact width along the direction orthogonal to the connecting direction, the space for the lower limbs in the intermediate part is secured. And stabilization of the ground contact state at the end portion can be appropriately made compatible.

  Since the present invention is configured as described above, it does not involve a large dismantling work or the like when increasing or decreasing, and the number and type of legs are configured as rationally as possible by using intermediate legs as appropriate end legs. can do. And, when the ground contact width is changed by adding or removing the end legs, the position where the wagon or leg is inserted under the top plate is maintained with the lower limb space kept substantially constant regardless of whether the intermediate leg exists or not. It is possible to suitably achieve both the advantage of not being performed and the appropriate grounding state when the intermediate leg is positioned at the end.

  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 is configured so that a large-sized desk of a required scale can be arbitrarily configured by connecting an appropriate number of top boards 1, and so-called all the legs that support the top board 1. The gist is that the intermediate leg 2 having a narrow ground contact width is used. That is, as shown in FIGS. 2 and 3, the adjacent top plates 1 and 1 are supported by the half halves 2a and 2a of the single intermediate leg 2, and the intermediate legs that support the end of the large desk. 2, the top plate 1 is supported on the half piece 2 a, and an end member 3 is detachably added so as to cover the remaining half piece 2 a, and the intermediate leg 2 and the end member 3 An end leg 4 having a wide ground contact width is formed.

  More specifically, the intermediate leg 2 is formed by rigidly connecting a stay 22 extending horizontally to the upper ends of the two leg columns 21, 21, and the leg column 21 supports the vicinity of the central portion in the longitudinal direction of the stay 22. The adjuster 21a is provided at the lower end. As shown in FIG. 1, the top plate 1 is supported in a state where it can be used facing each other at a position that bisects the longitudinal direction of the stay 22 as shown in FIG. For the width direction, as shown in FIG. 3, the side edge 1 a of the adjacent top plate 1 is supported by the half halves 2 a and 2 a of the stay 22, and screw passing holes provided in the stay 22 are provided. The top plate 1 is fixed using screws from below using 22a (see FIG. 2). On the left and right side surfaces of the stay 22, a rigid block-shaped beam attachment portion 22 b made by die casting or the like is firmly attached at intermittent positions in the longitudinal direction, and between the intermediate legs 2 and 2. Are detachably connected by fitting the beam 5 to the corresponding beam mounting portion 22b before placing the top plate 1 and screwing the beam 5 to the beam mounting portion 22b at a position not shown. Therefore, when disassembling, the top plate 1 is removed by removing the screw that has been fixed to the stay 2, and the beam 5 is detached from the beam attachment portion 22b by removing the screw attached to the beam attachment portion 22b. The connection between the intermediate legs 2 and 2 is released.

  On the other hand, as shown in FIG. 4, the end member 3 has a frame structure including left and right side frames 31, an upper frame 32, and a lower frame 33, and a spacer 34 is attached to the front surface of the upper frame 32. The side frame 31 is provided with an adjuster 31a at the lower end. Then, the vertical cover 35 is attached to the position where the outer surface of the side frame 31 is made up, and the horizontal cover 36 is attached to the position where the upper face of the upper frame 32 and the spacer 34 are made up at the same time, and further surrounded by these frames 31, 32, 33. A face member 37 is attached to a position where the space to be closed is closed from the outside, and finished as a panel leg having a recess 3a on the inside as shown in FIG. A reinforcing bar 38 is provided between the side frames 31 and 31 between the upper frame 32 and the lower frame 33. However, it is not always necessary to provide the reinforcing frame 38 when the strength is sufficient.

  When the end member 3 is attached to the intermediate leg 2, as shown in FIG. 5, the beam attaching portion 22b attached to one side of the stay 22 is removed in order to reduce the amount of squeezing into the recess 3a. . At this time, the beam 5 is not attached to the beam attachment portion 22b, and the beam attachment portion 22b attached to the opposite side does not need to be removed together with the top plate 1. There is no need to disassemble the structure part of the desk. Then, as shown in FIGS. 2, 3, and 6, the half half 2 a along the connecting direction of the stay 22 of the intermediate leg 2 is inserted into the half half 2 b of the leg column 21 in the recess 3 a of the end member 3. (See FIG. 6). At this time, the spacer 34 and the side cover 36 provided integrally with the upper frame 32 are covered on the half portion 2a of the stay 22 of the intermediate leg 2, and the lower end portion of the side frame 31. Is grounded to the outside of the leg column 21 of the intermediate leg 2 so as to form the end leg 4 integrally with the intermediate leg 2. At this time, the thickness of the spacer 34 substantially corresponds to the thickness of the top plate 1, and the edge 1 a of the top plate 1 is concealed by the spacer 34.

  At this time, since the screw passage hole 22a opened in the half portion 2a of the stay 22 to which the top plate 1 is not attached is open, the screw passage hole 22a is screwed as shown by the arrow in FIG. Is inserted into the spacer 34 and the end member 3 is fixed to the intermediate leg 2. Therefore, the end leg 3 can be removed from the intermediate leg 2 by removing this screw.

  As shown in FIG. 5 and the like, when the top plate 1 is placed on the stay 22 of the intermediate leg 2, the grounding portion of the leg column 21 of the intermediate leg 2 is grounded near the counter-use edge 1c of the top plate 1. Moreover, the stay 22 is configured to be relatively thin, and a sufficient distance from the lower surface of the stay 22 to the floor is secured. For this reason, a lower leg space S that is continuous in the lateral direction as shown in FIG. 1 is secured below the top plate 3 including the front of the corner portion between the leg support 11 and the stay 12. The wagon W can be inserted at an appropriate position.

  Next, the handling at the time of increase / decrease series, connection, and separation using this desk system will be described.

  When increasing the number of top plates, first, as shown in FIG. 7A, the end member 3 constituting the end leg 4 of the existing desk A is removed. At this time, it is not necessary to disassemble the top plate 1, the intermediate leg 2, and other structural parts constituting the existing desk A. And the edge part of the top plate 1 which should be added is mounted in the half part 2a of the stay 22 open | released in the intermediate leg 2 which attached the said edge part member 3 as shown in the same figure (b). Support. This operation only involves the operation of attaching the beam attachment portion 22b to the stay 22 and connecting the beam 5 to the intermediate leg 2 that will be newly positioned at the end portion. Then, if the end member 3 previously removed as shown in FIG. 5C is added to the intermediate leg 2 which is newly positioned at the end, the intermediate leg 2 is newly added in an increased state. The leg 2 can be used as the end leg 4.

  When the top plate is reduced, the top plate 1 and the intermediate leg 2 of the desk portion A left by the reduction as shown in FIGS. The required intermediate leg 2 and end leg 4 are removed together with the top board 1 without disassembling other structural parts. Then, in the intermediate leg 2 that is newly positioned at the end, the beam mounting portion 22b is removed from the half half that is opened when the top plate is removed, and then shown in FIG. Thus, if the end member 3 attached to the end leg 4 removed previously is added, the intermediate leg 2 can be newly used as the end leg 4 in a reduced state.

  Further, when connecting the desks, first, as shown in FIGS. 8A to 8B, the end member 3 is removed from the end legs 4 of the desks B to be connected. At this time, as described above, it is not necessary to disassemble the structural parts such as the top board 1 and the intermediate leg 2 of the existing desk B. Then, for each half half 2a of the stay 22 opened in each intermediate body 2 to which the end member 3 is attached, a beam attaching portion 22b is attached to the stay 22, and the beam 5 is newly installed. If the left and right edges of the top plate 1 are installed, the connection between the desks can be completed as shown in FIG.

  When the desks are separated, the top plate 1 and intermediate legs 2 and other structural parts of the desk part B to be left by the separation are first disassembled as shown in FIG. Without removing the top plate 1 and the beam 5. Then, in the intermediate leg 2 that will be newly positioned at the end of each separated desk B, the beam mounting portion 22b is removed from the half portion 2a of the stay 22 that is opened by removing the top plate. In addition, by adding an end member 3 as shown in FIG. 4B, the intermediate leg 2 is newly used as the end leg 4, and each desk is independent as shown in FIG. B can be used.

  As described above, the desk system according to the present embodiment supports the adjacent top plates 1 and 1 to each one half 2a of the common intermediate leg 2 when the top plate 1 is connected to form a large desk. An end leg 4 can be configured by detachably adding an end member 3 so as to cover the open half half 2a with respect to the intermediate leg 2 to be positioned at the end. It is.

  In this way, even if the intermediate leg 2 located at the end is positioned in the middle due to the increase / decrease sequence, or the intermediate leg 2 located in the middle is located at the end, the intermediate leg 2 On the other hand, any form of the end leg 4 and the intermediate leg 2 can be obtained simply by attaching and detaching the end member 3, so that it is unnecessary to replace the intermediate leg and the end leg one by one. it can. Moreover, since the intermediate leg 2 can support the adjacent top plates 1 and 1 at the same time, the intermediate leg 2 does not overlap and overlaps the adjacent boundary of the top plate, and the lower leg space S is widened along the width direction. Can do. Furthermore, although the intermediate leg 2 and the end member 3 overlap at the end, the end member 3 is attached so as to cover a part of the intermediate leg 2, so that it is compared with the sum of the respective width dimensions. Thus, the function of the end leg 4 having a wide ground contact width can be effectively exhibited while suppressing bulkiness in the squeezed portion 2b of the intermediate leg 2 shown in FIG. In the above, the end member 3 is attached so that the grounding width of the intermediate leg 2 having a narrow grounding width can be widened to form the end leg 4. It is possible to appropriately balance the securing of the lower limb space S and the stabilization of the ground contact state at the end.

  When the top plate 1 is added, the end member 3 is removed from the end leg 4 without disassembling the top plate 1, the intermediate leg 2 and other structural parts constituting the existing desk A. The end portion that the top plate 1 to be added is supported on the half portion 2a that is opened in the intermediate leg 2 to which the member 3 is attached, and that the intermediate leg 2 that is newly positioned at the end portion is first removed. Since the end leg 4 can be configured by adding the member 3, the end leg 4 can be moved by reusing the end member 3 without unnecessary disassembly when the top plate 1 is added. The intermediate leg 2 and the intermediate leg 2 can be easily changed to the end leg 4, respectively, and the top plate 1 can be efficiently added.

  Further, when the top plate 1 is reduced, the required intermediate leg 2 and end leg 4 are attached without disassembling the top plate 1, the intermediate leg 2 and other structural parts of the desk portion A left by the reduction. The end member 3 attached to the end leg 4 previously removed is added to the half half 2a opened in the intermediate leg 2 which is removed together with the top plate 1 and newly positioned at the end. Since the end leg 4 can be configured by the above, when the top plate 1 is reduced, the position of the end leg 4 can be changed by using the end member 3 without being disassembled more than necessary. Therefore, the top plate 1 can be efficiently reduced.

  Further, when the desks B and B are connected to each other, the end members 3 are connected from the end legs 4 to the desks B to be connected without disassembling the existing top plate 1 and intermediate legs 2 and other structural parts. The desks B and B can be connected to each other by removing and mounting a new top plate 1 on the half half 2a opened at the intermediate leg 2 that will be located at the end of each desk B. Therefore, when the desks B and B are connected to each other, the top leg 1 can be installed by changing the end leg 4 to the intermediate leg 2 without unnecessary disassembly, and the desks B and B can be connected to each other. It becomes possible to carry out efficiently.

  Furthermore, when the desk is separated, the top plate 1 and other necessary members are removed without disassembling the top plate 1 and the intermediate leg 2 and other structural parts of the desk portion B to be left by the separation. The end leg 4 can be configured by adding the end member 3 to the half half 2a that is opened at the intermediate leg 2 that is newly positioned at the end of the desk B. During separation, the intermediate leg 2 newly positioned at the end can be changed to the end leg 4 by adding a little end member 3 without unnecessarily disassembling, and the desk can be separated efficiently. It is possible to perform well.

  As a specific structure for that purpose, the end member 3 has a panel leg shape in which a face member 37 is attached to the outside of the frame structure including at least the left and right side frames 31 and the upper frame 32 and the inside is recessed. There is a recess 3a, which is a recess, receiving a part of the intermediate leg 2 and a spacer 34 or a side cover 36 positioned in front of the upper frame 32 over the half half 2a of the intermediate leg 2, and the side frame 31 is Since the intermediate leg 2 is attached to the intermediate leg 2 so as to be positioned outside the leg support 21, the intermediate leg 2 can be appropriately covered to reduce the bulk, and the intermediate leg 2 can be moved in the falling direction. On the other hand, this can be effectively suppressed, and the recess 2a inside the frame structure can be effectively used as a part of the lower limb space S.

  The intermediate leg 2 includes a leg column 21 and a stay 22 that extends substantially horizontally to the upper end side of the leg column 21 and supports the top plate 1. An intermediate beam 2 is installed between the stays 22 and 22. Since the legs are detachably connected to each other, it is possible to easily cope with the increase / decrease stations and the connection / separation of the desks by simply attaching / detaching the top plate 1 and the beam 5. And since the leg support | pillar 21 is set as the structure earth | grounded on the counter-use edge 1c side of the top plate 1, securing of the leg space S can be shown effectively.

  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.

  For example, in the above-described embodiment, the present invention is applied to a double-sided desk in which a pair of top plates are arranged so as to be able to face each other.

  In addition, the spacer employed in the above embodiment is mainly for the purpose of concealing the edge of the top plate 1, and therefore it is not necessary to dare to provide it unless necessary.

  Furthermore, in the above embodiment, the beam mounting portion is removed when the end member is assembled to the intermediate leg. However, if there is little influence on the bulk, the half of the intermediate leg together with the beam mounting portion is placed in the recess of the panel. An embodiment configured to accept is also possible.

  Moreover, the support structure of the top plate in the stay is not limited to a mode in which the top plate is directly placed on the stay as described above, and may be a structure in which the top plate is indirectly supported by the stay through a beam.

  Moreover, in the said embodiment, although the panel leg-shaped thing was employ | adopted for the edge part member, when the presence or absence of a face material does not affect intensity | strength etc., a face material is omitted and the left and right side frames 31 and the upper frame 32 The upper frame 32 or its peripheral part is put on the half half 2a of the intermediate leg 2, and the side frame 31 is positioned outside the leg column 21 of the intermediate leg 2 so that the intermediate leg 2 may be attached.

  Furthermore, the present invention is not limited to the mode in which the intermediate leg is selectively switched to the end leg by adding or removing the end member, but the same can be achieved by using a deformable common leg for the intermediate leg and the end leg. The goal can also be achieved.

  For example, all shown in FIGS. 9A to 9C are common legs that are provided with leg posts and stays that are basically the same as those of the above-described embodiment, and support adjacent top plates to the common legs. The common leg 102 in FIG. 6A can be attached to and detached from an auxiliary leg 121x that selectively expands the ground contact width outside the leg column 121, and the common leg 202 in FIG. By attaching a leg blade 221x that selectively expands the ground contact width to the part, the common leg 302 in FIG. 5C can be repositioned in a direction that selectively expands the ground contact width relative to the stay 322. Thus, any of them can be used as an intermediate leg or an end leg.

  Even if such common legs 102, 202, 302 are used, the same effects as in the above embodiment can be obtained. That is, even if the leg located at the end is located in the middle due to the increase / decrease sequence, or the leg located in the middle is located at the end, the common legs 102, 202, 302 are not Since any form of an end leg and an intermediate leg can be taken as the form, it is possible to eliminate the need to replace the intermediate leg and the end leg one by one. Moreover, since these common legs 102, 202, 302 can simultaneously support the adjacent top plates, it is possible to avoid the inconvenience that the legs overlap and become bulky, and to widen the leg space. Furthermore, since these common legs 102, 202, and 302 exist as a single unit and do not overlap even at the end portions, it is possible to effectively avoid the bulk here. Also in this case, if the deformation is to change the shape of the intermediate leg with a narrow ground contact width and the end leg with a wide ground contact width along the direction orthogonal to the connecting direction, the lower limb space in the intermediate part It is possible to appropriately balance the securing of the ground and the stabilization of the ground contact state at the end.
