  Conventionally, when installing a target member such as a panel or a shelf on a top plate of a desk having a L-shaped top plate (so-called L-shaped desk) that refracts near the center, sandwiching a refracting portion near the center In order to install the target member in the installation space having two surfaces on the left and right, a support column corresponding to this support column and a support column corresponding to this support column is provided according to the refraction angle (not limited to a right angle) of the L-shaped refraction part. It was necessary to use it.

  In addition to the L-shaped desk, when there is a need to change from two installation spaces that refract in the center to one installation space due to a design change or layout change, the conventional installation method uses a central refracting section. Since a dedicated support and a support device corresponding to this support are used, it is necessary to replace the support device. That is, the conventional installation method is disadvantageous in terms of cost when a design change or a layout change due to introduction of a new target member occurs.

  In order to cope with such a change, it is conceivable to provide a mechanism that allows angle adjustment or the like to the support device or the support column, but such a mechanism usually decreases the stability and strength of the support column, The necessity of severely limiting the weight of the target member installed on the column arises.

  In view of the above problems, an object of the present invention is to provide a column support device that can flexibly cope with a design change and has high stability.

  In order to solve the above-mentioned problems, the present invention can flexibly cope with a design change by providing an insertion hole having an inner surface along each side surface when the support columns face different directions, and is stable. This makes it possible to provide a high-strength support device.

Specifically, the present invention is a support device for supporting a support column having a substantially rectangular cross section, wherein the support column is upright and one side surface of the support column is oriented in a predetermined direction with respect to the support device. Select either the installation state or the second installation state in which the column is upright and the side surface is directed in a direction different from the predetermined direction by a predetermined angle equal to or less than a right angle in the horizontal plane. And the support device is provided with an insertion hole having a substantially polygonal cross section, the insertion hole having a plurality of inner side surfaces corresponding to each side of the polygon, Among them, the first inner side surface along one side surface of the support column inserted in the first installation state and the second inner side surface along the side surface of the support column inserted in the second installation state The column supports that are adjacent on one side and whose inner angle forms a complementary angle of the predetermined angle. It is a device.

  Here, the target member installed using a support | pillar is a panel, a shelf, a storage tool, a lighting fixture etc., for example. However, the target member is not limited to the above example.

  The insertion hole having a substantially polygonal cross section has at least a first inner surface and a second inner surface. The first inner surface is an inner surface along the side surface of the support column in the first installed state, and the second inner surface is an inner surface along the side surface of the column in the second installed state. Since the insertion hole has the first and second inner surfaces, the column having a substantially rectangular cross section selects one of the two directions (first installation state or second installation state). Can be inserted. Furthermore, since the method of installing the column is a method of inserting the column into the insertion hole and keeping it along the inner surface, the column is installed with high stability.

  That is, the column support device according to the present invention can support the column with high stability, and can select the installation direction of the column without sacrificing this high stability. In addition, according to the present invention, even when a design change or a layout change is necessary, it is possible to cope with the change without exchanging the support device. .

  Moreover, the support | pillar support apparatus which concerns on this invention makes 3rd inner side along the said support | pillar inserted in said 1st installation state with said 1st inner surface by making a right angle with said 1st inner surface. And a fourth inner surface along the support column inserted in the second installed state together with the second inner surface by making a right angle with the side surface and the second inner surface. Good.

  By providing a third inner surface that is perpendicular to the first inner surface and a fourth inner surface that is perpendicular to the second inner surface, it is possible to support a column having a substantially rectangular cross section from two directions. Thus, the stability of the installed support can be further improved.

  The support column inserted in the first installation state is fixed to at least one of the first inner surface and the third inner surface, and the support column inserted in the second installation state. May be fixed to at least one of the second inner surface and the fourth inner surface.

  By supporting the support column from two directions and fixing it to at least one of the supported inner side surfaces, the support column is firmly fixed in the insertion hole. Moreover, it is good also as improving the intensity | strength of fixation further by fixing using the inner surface of 2 directions.

Moreover, this invention can also be grasped | ascertained as a desk provided with the said support | pillar support apparatus. That is, the present invention includes a top plate used as a desk surface, a leg portion that supports the top plate, a support column having a substantially rectangular cross section for installing a target member above the top plate, and the support column upright. And a first installation state in which one side surface of the support column is oriented in a predetermined direction with respect to the leg portion, and a predetermined value not more than a right angle in a horizontal plane with respect to the predetermined direction and the side surface is upright. An insertion hole having a substantially polygonal cross section that can be inserted into the leg portion regardless of the installation state of the second installation state directed in a different direction by an angle of A fixed portion for fixing the inserted support column, and the insertion hole has a plurality of inner side surfaces corresponding to each side of the polygon, and the first installation state among the plurality of inner side surfaces. The first inner side surface along one side surface of the support column inserted in step 2 and the second installation state are inserted. The second and the inner surface along the side surface of the strut that is, adjacent one side, and the interior angles form a supplementary angle of the predetermined angle, a desk.

  According to the present invention, it is necessary to change from the state in which the target member is installed in the left and right installation spaces across the refracting portion near the center of the L-shaped desk to the installation in one installation space. In this case, it is possible to cope with the change simply by exchanging the column without exchanging the legs of the desk. Further, according to the present invention, since the insertion hole for the column is provided in the leg portion of the desk, and the configuration of the outer shell and the like is shared, a desk having high arrangement flexibility and stability at a low cost is provided. It becomes possible to do.

  Moreover, the said support | pillar has the to-be-fixed part extended in a longitudinal direction on the side surface of this support | pillar, and the said support | pillar may be fixed to the said inner surface in the arbitrary positions of the said to-be-fixed part. In order to enable height adjustment in the conventional method of fixing the column using the top plate or the back beam of the desk, the column is exchanged according to the desired height, or an expansion / contraction mechanism is provided on the column itself There was a need. On the other hand, according to the present invention, since the column is fixed at an arbitrary position of the fixed portion, the fixed height of the column can be freely adjusted.

  More specifically, the column has a groove extending in the longitudinal direction on a side surface, and the inner surface has a column fixing hole at a position corresponding to the groove when the column is inserted into the insertion hole. And a support member for fixing the biasing member to the fixing hole, and a biasing member fixed to an arbitrary position in the groove by biasing the inner side of the groove. May be fixed to the inner surface.

Although illustration is omitted, a hook is provided inside the back cover 27, and the back cover is attached to the back surface of the leg portion 2 by being locked in the locking hole 73.

  FIG. 4 is a cross-sectional view of the column 6 according to the present embodiment. In this embodiment, the cross-sectional shape of the column 6 is a rectangle, and the cross-sectional shape of the insertion hole 7 is also a rectangle corresponding to the cross-sectional shape of the column 6. And the support | pillar 6 and the insertion hole 7 are formed in the dimension which the side surface of 4 surfaces of the support | pillar 6 and the inner surface of 4 surfaces of the insertion hole 7 just contact in the state in which the support | pillar 6 was inserted.

  The column 6 has a substantially rectangular cross section and has a groove extending in the longitudinal direction on the side surface. The column 6 is a member for installing a panel, a shelf or the like on the top plate 3 of the desk 1a. As for the cross-sectional shape of the support column 6, the partition wall 61 extends from the base portion 60 in four directions, and apexes Q are formed at the four corners in the cross section of the support column 6. The wall surfaces 62 extend from one vertex Q toward the other vertex Q, respectively. The wall surface 62 extending from one vertex Q and the wall surface 62 extending from the other vertex Q extend to the middle of both vertices Q, but they do not contact each other. Accordingly, an opening 63 is formed between the opposing wall surfaces 62 and 62 (hereinafter referred to as “a pair of wall surfaces 62”). Further, a groove portion 64 is formed by the pair of wall surfaces 62, the partition wall 61, and the base portion 60. The opening 63 and the groove 64 extend over the entire length in the longitudinal direction of the column 6.

  The support 6 is inserted into the insertion hole 7. And in this support | pillar 6, the support | pillar 6 for fixing a support | pillar 6 to the inner surface 71 by arbitrary height using the sliding block shown by FIGS. 5-8, and thereby installing a panel, a shelf, etc. It can be provided to the user. Hereinafter, the sliding block will be described.

The sliding block includes an urging member 82 shown in FIG. 5 and a base member 83 shown in FIG. The two are completely separate members. The urging member 82 includes an urging portion 82a having a contour shape, a protruding portion 82b protruding in one direction from the urging portion 82a, and a protruding portion protruding from the urging portion 82a in a direction opposite to the protruding portion 82b. 82c. The urging portion 82a is formed symmetrically with respect to a line connecting the points where the protruding portions 82b and 82c are provided. The specific shape of the urging portion 82a is a shape that slightly follows the center line of line symmetry in the vicinity of each protrusion (region indicated by R1 in the drawing), and further approaches the center of the urging portion 82a (in the drawing). The region indicated by R2 is formed in an arc shape so as to be away from the line-symmetrical center line, and in the vicinity of the center of the urging portion 82a (region indicated by R3 in the figure), the shape is substantially parallel to the line-symmetrical center line. By adopting such a shape for the urging portion 82a, the urging portion in the region indicated by R3 can be easily bent in the direction perpendicular to the drawing with the urging portion in the region indicated by R1 as an axis. The urging portion 82a can exert an urging force in a direction perpendicular to the drawing. The protrusion 82c has a substantially cylindrical protrusion shape, and the protrusion 82b has a shape having a slight lateral width as compared with the protrusion 82c. Note that this lateral width is slightly smaller than the width of the opening 63 of the column 6.

  As shown in FIG. 6, the base member 83 is provided with three screw holes 83b in the center of the base portion 83a. Further, a stepped portion 83c is provided on the one end surface side of the base portion 83a along the longitudinal direction of the base portion 83a. Note that the width (width in the vertical direction of the drawing) of the stepped portion 83 c is slightly smaller than the width of the opening 63 of the column 6.

  The function of the above-described biasing member 82 and base member 83 as a sliding block in the groove 64 of the column 6 will be described with reference to FIG. FIG. 7 shows a sliding block in the groove 64 of the support column 6. The groove portion 64 is formed by the respective inner wall surfaces of the partition wall 61 and the wall surface 62 extending from the central portion 60 as described above, and the cross-sectional shape thereof is a substantially hexagonal shape. Here, as shown in FIG. 7, the substantially hexagonal apexes in the cross section of the groove 64 are referred to as S1 to S6, and the apexes constituting the opening 63 are referred to as T1 and T2.

  First, as shown in FIG. 7A, the urging member 82 is slid from the opening 63 with respect to the groove 64. At this time, the protrusion 82c is located in the back of the groove 64 (near the vertices S3 and S4), and the protrusion 82b is located in the vicinity of the opening 63 (between the vertices T1 and T2). Moreover, the part located in area | region R3 of the urging | biasing part 82a is located in the inner wall surface vicinity between the vertexes S1 and S2 of the groove part 64, and between the vertexes S5 and S6. At this time, since a slight gap exists between the urging portion 82a and the inner wall surface, the urging portion 82a is not bent.

  In the state shown in FIG. 7A, the urging member 82 can be freely moved in the groove portion 64 of the support column 6 via the protrusion 82b. After the urging member 82 is moved to an arbitrary position of the groove portion 64, the base member 83 is inserted into the groove portion 64 as shown in FIG. At this time, the base member 83 is brought into contact with the surface of the base member 83 where the stepped portion 83c is not provided on the surface of the biasing portion 82a of the biasing member 82 where the protruding portion 82b protrudes. A stepped portion 83 c is located in the opening 63.

  In the state shown in FIG. 7B, the urging portion 82 a of the urging member 82 is pushed into the deep part of the groove portion 64 by the base member 83, so that the portion located in the region R <b> 3 of the urging portion 82 a is the partition wall 61. Will contact the inner wall surface (between vertices S2 and S3 and between vertices S4 and S5). The width of the inner wall surface becomes narrower as it goes deeper into the groove portion 64. Therefore, in the state shown in FIG. 7B, the urging portion 82a of the urging member 82 bends as described above, and due to the bending, the urging portion 82a is displaced from the wall surface 62 near the opening 63 with respect to the base member 83. The urging force that presses against is generated. As a result, the sliding block composed of the urging member 82 and the base member 83 is fixed at an arbitrary position in the column 6.

  Then, a screw is fastened from the outside through a fixing installation hole 72 provided on the inner side surface 71 of the insertion hole 7 to the screw hole 83b of the sliding block fixed in the support column 6, so that the leg 2 It becomes possible to erect the column 6.

  Here, the manner of changing the fixed position of the sliding block once fixed at an arbitrary position will be described with reference to FIG. First, as shown in FIG. 8A, the base member 83 to which the urging force is applied to the urging member 82 is shifted to the position where the urging force is not applied from the urging member 82 in the direction of the arrow. . At this time, when the groove portion 64 is viewed from the cross-sectional direction, it is as shown in FIG. The urging member 82 is in the state shown in FIG. 8B when the base member 83 is removed. At this time, the base member 83 exists in a space other than the space where the urging member 82 exists in the groove portion 64.

  However, as shown in FIG. 8B, the base member 83 is in a state of interfering with the protruding portion 82 c of the biasing member 82 in the groove portion 64. This means that even when the base member 83 is released from the urging force by the urging member 82, the base member 83 is not freely movable in the groove portion 64, and its movement is limited by the urging member 82. means. Thereby, it can avoid that the base member 83 leaves | separates from the biasing member 82 unnecessarily. After the base member 83 is released from the urging force by the urging member 82, the base member 83 is removed from the opening 63, the urging member 82 is moved to a new position, and then the base member 83 is reinserted in the groove 64. The sliding block can be fixed by inserting it into.

  In addition, when attaching target members, such as a beam 9, a panel, and a shelf, to the support | pillar 6, it can attach to the arbitrary positions of the support | pillar 6 using the same sliding block.

  Next, a procedure for attaching the column 6 to the leg 2 in the present embodiment will be described. FIG. 9A to FIG. 9E are views showing a procedure for attaching the column 6 to the leg portion 2 in the present embodiment. First, the back cover 27 and the opening cover 29 provided on the leg 2 are removed (see FIG. 9A). When the back cover 27 is removed, the installation hole 72 for fixing the support 6 is exposed on the back of the leg 2, and when the opening cover 29 is removed, the insertion hole for inserting the support 6 into the upper surface of the leg 2. 7 is exposed (see FIG. 9B).

  Further, the sliding block is fixed at an arbitrary position in the groove of the support column 6. Since the procedure for fixing the sliding block has already been described, a description thereof will be omitted. Here, the sliding block determines in advance how much length of the upper part of the column 6 is exposed on the leg 2 or the top plate 3, and the column 6 below the column 6 is determined as described above. It is attached at a position corresponding to the installation hole 72 for fixing the column 6 provided in the leg portion 2 in a state of being inserted into the insertion hole 7 while leaving the exposed length. In order to secure strength and stability, it is preferable that two or more sliding blocks are attached.

  Next, the column 6 is inserted into the insertion hole 7 through the opening (see FIG. 9C). The inserted support column 6 is aligned so that the position where the sliding block is attached and the position of the installation hole 72 of the inner surface 71 coincide.

  Then, at that position, a screw is fastened from the outside to the screw hole 83 b of the sliding block through a fixing installation hole 72 provided on the inner side surface 71 of the insertion hole 7. The column 6 is fixed and the column 6 is erected on the leg 2. Finally, the back cover 27 is attached again to the back surface of the leg portion 2 to complete the attachment of the support 6 (see FIG. 9D).

  In addition, according to the support | pillar attachment structure which concerns on this embodiment, since a sliding block can be fixed to arbitrary positions, it is possible to adjust the installation height of a support | pillar freely (refer FIG. 9E). ).

  FIG. 10 is a cross-sectional view of the leg 2 in a state in which the installation of the column 6 to the leg 2 is completed in the present embodiment. By attaching the back cover 27, the installation holes 72 and the locking holes 73 on the back of the legs 2 and the heads of the screws used to attach the support columns 6 are avoided from being exposed, and the appearance is good. Is possible.

Moreover, FIG. 11 is sectional drawing which shows a mode that the support | pillar 6 was installed in a pair of leg part 2 of the desk 1a which concerns on this embodiment. Thus, by attaching the support | pillar 6 to the leg part 2, it becomes possible to attach a panel and a shelf using this support | pillar 6. FIG. That is, according to this embodiment, the desk 1a
It is possible to install a panel, a shelf or the like stably and at an arbitrary height.

  FIG. 12 is a diagram showing a variation when the beam 9 is attached to the installed support column 6 in the present embodiment. Only one beam 9 may be installed as shown in FIG. 1, or two beams 9 may be installed as shown in FIG. That is, the number and interval of the beams 9 can be appropriately set according to various requirements such as the shape of the panel or shelf to be installed, the installation position of the lighting fixture to be installed, and the like.

  In this embodiment, since the column 6 is inserted into the insertion hole 7, the insertion hole 7 is joined to the column 6 to be fixed as compared with the conventional mounting structure in which the mounting device is installed on the top plate or the like. The area of a part can be taken widely. For this reason, it is easy to raise intensity | strength and stability compared with the conventional attachment method. In particular, in this embodiment, since the insertion hole 7 and its inner surface 71 extend in the same direction as the direction in which the leg portion 2 extends, it is easy to increase the length of the joint portion.

  In this embodiment, the structure for fixing the column 6 is a separate member as a sliding block and a screw, but the structure for fixing the column 6 is provided integrally with the inner surface 71. There may be. For example, it is good also as fixing a support | pillar to an inner surface by providing locking parts, such as a hook, in an inner surface, and providing a to-be-latched part in a support | pillar.

As in the first embodiment, the number and interval of the beams 9 are preferably set as appropriate according to various requirements such as the shape of the panels and shelves to be installed, the installation positions of the lighting fixtures to be installed, and the like.

<Third embodiment>
In the second embodiment, the refraction angle of the top plate 3B in the horizontal plane is a right angle, but this refraction angle may be an angle larger than the right angle, for example, an angle of 120 degrees or 135 degrees. FIG. 20 is a diagram illustrating an overall configuration of a desk 1f according to the present embodiment. The desk 1f according to the present embodiment includes a top plate 3C having a refraction angle of 120 degrees in plan view as a whole. It is the desk 1f supported. Here, the structure of the leg part 2 which supports the top plate 3C at both ends is the same as the L-shaped leg part 2 described in the first and second embodiments.

  Further, the leg 2C (corresponding to the column support device of the present invention) has a configuration substantially similar to that of the leg 2B described in the second embodiment. However, the leg 2C is characteristic in that the shape of the insertion hole 7C provided in the leg 2C is substantially pentagonal in cross section, unlike the leg 2B having a substantially rectangular cross section.

The leg 2C has an insertion hole 7 having a substantially pentagonal cross section in order to correspond to a refraction angle that is not a right angle of the top plate.
C is provided. FIG. 21 is a cross-sectional view showing the insertion hole 7C provided in the leg 2C according to the present embodiment. In this insertion hole 7C, it is possible to insert a column 6C having a shape along the inner wall of the insertion hole 7C and having a substantially pentagonal cross section (see FIG. 22A).

  The structure of the pillar 5C having a substantially pentagonal cross section is roughly the same as the pillars 6 and 6B having a substantially rectangular cross section described in the first and second embodiments except that the cross section is substantially a pentagon, such as having a groove on the side surface. The description is omitted because it is similar. By inserting the pillars 6C having a substantially pentagonal cross section, panels and shelves can be installed on both sides of the refracted top plate 3C.

  The insertion hole 7C provided in the leg 2C has a substantially pentagonal cross section. Hereinafter, the two inner surfaces of the insertion hole 7C having the same angle as the refraction angle of the top plate 3C are referred to as a first inner surface 71a and a second inner surface 71b. This pentagon is a pentagon in which two sides corresponding to the first inner side surface 71a and the second inner side surface 71b have the same length as the short side of the rectangle of the cross section of the insertion hole 7, respectively. For this reason, in addition to the pillar 6C, the pillar 6 (see FIG. 4) having a substantially rectangular cross section that can be inserted into the insertion hole 7 can be inserted into the insertion hole 7C.

  Further, when inserting a column 6 having a substantially rectangular cross section, it is possible to select and insert the column 6 in the direction (installation state) according to which side of the top plate 3C the panel or shelf is installed. Yes (see (b) and (c) of FIG. 22). That is, the L-shaped desk 1f according to the present embodiment can select whether the panel and the shelf are attached to the entire surface or only one side, similarly to the desk 1c shown in the second embodiment. When attaching to only one side, you can select which side to attach.

  About the method of installing the support | pillar 6 or 6C in the leg part 2C, it is substantially the same as the installation method of the support | pillar shown in the said embodiment. That is, first, the back cover and the opening cover are removed, and the installation holes for fixing the support columns 6 and 6C, the locking holes for locking the back cover, and the opening of the insertion hole are exposed (not shown). And the support | pillar 6 or 6C provided with the sliding block is inserted, it fixes with a screw, and a back cover is attached (illustration is abbreviate | omitted).

  FIG. 23 is a cross-sectional view showing a state in which the columns 6 and 6C are installed on the legs 2 and 2C of the L-shaped desk 1f according to the present embodiment. That is, according to this embodiment, as in the second embodiment, the three columns 6, 6, 6C are installed on the L-shaped desk 1f, and all the upper parts of the top plate 3C are the target members such as panels and shelves. (See FIG. 23 (a)), and two struts 6 and 6 are installed on the L-shaped desk 1f, and only one side of the top of the top plate 3C is provided. Can also be used as an installation space for the target member (see FIG. 23B).

  For example, when it is desired to provide a panel on the left side, the support column 6 is inserted in a direction parallel to the support column 6 inserted in the left end leg 2 as shown in FIG. It is fixed to the inner side surface 71a (first installation state). When it is desired to provide a panel on the right side toward the right side, the panel is inserted in a direction parallel to the column 6 inserted into the leg 2 at the right end and fixed to the second inner surface 71b (second installed state). . In other words, when a column 6 having a substantially rectangular cross section is inserted into the insertion hole 7 </ b> C, the column 6 is inserted in parallel with the opposite column 6 used as a pair when the target member is installed using the column 6.

Here, the angle formed by the orientation of the support column 6 in the first installation state and the orientation of the support column 6 in the second installation state has a relationship between the refraction angle and the complementary angle of the top plate 3C. For example, when the refraction angle of the top plate 3C is 120 degrees, the angle formed by the direction in which the support 6 in the first installation state faces and the direction in which the support 6 in the second installation state faces is 60 degrees. When the refraction angle of the top plate 3C is 135 degrees, the angle formed by the orientation of the support column 6 in the first installation state and the orientation of the support column 6 in the second installation state is 45 degrees ((( b) and (b) of FIG. 24).

  The insertion hole 7C has a third inner side surface 71c and a second inner side surface 71c along the support column 6 inserted in the first installed state together with the first inner side surface 71a by making a right angle with the first inner side surface 71a. And a fourth inner side surface 71d along the column 6 inserted in the second installed state together with the second inner side surface 71b by making a right angle with the inner side surface 71b. By having such third inner side surface 71c and fourth inner side surface 71d, the support column 6 inserted into the insertion hole 7C is supported from two directions, and high stability can be obtained.

  In this embodiment, the L-shaped desk whose top plate has a refraction angle of 120 degrees has been described. However, this angle is merely an example, and the angle can be appropriately set for each embodiment. . FIG. 24 is a cross-sectional view showing a state in which the columns 6 and 6C are installed on the legs of an L-shaped desk provided with a top plate having a refraction angle of 135 degrees in plan view.

  In the present embodiment, the same fixing method as in the first and second embodiments, that is, the method of fixing to the first inner side surface 71a or the second inner side surface 71b using a sliding block and a screw has been described. . However, the third inner side surface 71c or the fourth inner side surface 71d may be further used for fixing, or a fixing method that does not use a sliding block and a screw, that is, as illustrated in the first embodiment, A method of fixing the column to the inner surface using a locking part provided on the side surface and a locked part provided on the column may be employed.

  According to this embodiment, when installing a column 6 having a substantially rectangular cross section, it is possible to select and install the orientation of the column 6 and when either installation state (orientation of the column 6) is selected. Even so, it is possible to provide a column support device with high stability.
