[Technical Field]
[0001] One aspect of the present invention relates to a desk. [Background technology]
[0002] Conventionally, there have been desks in which the assembly of desk tops can be formed into a predetermined shape by arranging multiple desks (including tables and desks) in a predetermined layout. Patent Document 1 discloses a table that can be easily arranged in various layouts such as a circular layout or a U-shaped layout, has high storage capacity even when multiple tables are used, and allows tables to be efficiently stored when not in use. Patent Document 2 discloses desks that form a cluster by arranging three desks around one point. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-187336 [Patent Document 2] Japanese Patent Application Laid-Open No. 2012-65820 Summary of the Invention [Problem to be solved by the invention]
[0004] However, when trying to create a desk with legs like those in Patent Document 1 while maintaining an arrangement that can be arranged like Patent Document 1 or 2, there is an issue with stability to prevent the desk from tipping over. That is, in order to improve stability, it is effective to arrange the legs so that they are spaced apart at greater intervals where they come into contact with the floor, but when attempting to do so, the front legs end up overhanging the front of the tabletop, which creates the issue of the legs of adjacent desks interfering with each other when the desks are combined. [Means for solving the problem]
[0005] The present invention provides the following means to solve the above problems.
[0006] A desk according to one aspect of the present invention includes a tabletop and a first leg portion that protrudes from a first edge of the top plate when viewed vertically from above and supports the top plate; a second leg portion that protrudes from a second edge of the top plate when viewed vertically from above and supports the top plate; When the point where a first line connecting both ends of the first edge and a second line connecting both ends of the second edge intersect is defined as the apex, The first region, in which the first leg passes through a first plane including the first straight line and the vertical direction, is moved symmetrically with respect to a plane including the bisector of the apex and the vertical direction, and the second region, in which the second leg passes through a second plane including the second straight line and the vertical direction, do not overlap with each other.
[0007] According to the above-mentioned desk, when multiple desks are arranged adjacent to each other, the first and second legs of adjacent desks do not interfere with each other. In this case, the first and second legs of the desks can be arranged to cross each other when viewed vertically from above, which allows the desk fulcrums to be positioned over a wide range, making the desks stable.
[0008] In the above-mentioned desk, preferably, the first leg and the second leg are arranged symmetrically with respect to the bisector of the top when viewed from vertically above, and the first area and the second area do not overlap in the height direction.
[0009] With the above-mentioned desk, simply by making the bending positions of the first leg and the second leg at different heights, the first leg and the second leg can be configured not to interfere with each other when the desks are placed adjacent to each other.
[0010] In the above-mentioned desk, preferably, the first leg extends vertically upward from a contact portion with the floor, bends at a first height position, bends upward at a second height position higher than the first height, and is connected to the top board, the second leg extends vertically upward from a contact portion with the floor, bends at a third height position that is a height between the first height and the second height, bends upward at a fourth height position that is higher than the third height, and is connected to the top plate; The first leg is located to the right of where a user sits or stands in use.
[0011] According to the above-described desks, when multiple desks are arranged adjacent to one another, the second leg of one desk is inserted into the rear of the first leg of the desk located to the left of the desk. Meanwhile, the first leg of the desk is placed in front of the second leg of the desk located to the right. By enabling such an arrangement, the arrangement is easier than the above-described arrangement in which the left and right are reversed.
[0012] Preferably, the desk further includes a third leg and a fourth leg that support the top board together with the first leg and the second leg, the third leg portion and the fourth leg portion are disposed closer to a position where a user sits or stands during use than the first leg portion and the second leg portion; The first leg and the second leg are each equipped with a caster, and the third leg and the fourth leg are not equipped with a caster.
[0013] The desk can be easily moved by lifting the front side of the desk, where the user sits or stands. After the desk is set up, the desk is less likely to shift position if the third and fourth legs are in contact with the floor.
[0014] Preferably, the desk further includes a third leg and a fourth leg that support the top board together with the first leg and the second leg, The tabletop can be tilted in the opposite direction to the position where the user sits or stands when in use, When viewed vertically from above, the first leg portion, the second leg portion, the third leg portion, and the fourth leg portion extend substantially parallel to one another, The distance between the first leg and the second leg is smaller than the distance between the third leg and the fourth leg.
[0015] According to the above desk, the desk can be configured to be stored in a space-saving manner.
[0016] A desk according to one aspect of the present invention includes a tabletop and a first leg portion that protrudes from a first edge of the top plate when viewed vertically from above and supports the top plate; a second leg portion that protrudes from a second edge of the tabletop when viewed vertically from above and supports the tabletop, When another desk of the same shape is placed close to the desk at a specified angle, When viewed from above vertically, the first leg of the desk and the second leg of the other desk intersect with each other at a predetermined intersection position, At the intersecting position, the first leg and the second leg are at different heights.
[0017] According to the above desk, it is possible to configure the desk so that the first leg and the second leg of the desk and another desk placed close to each other do not interfere with each other. [Brief explanation of the drawings]

[0019] A desk according to one embodiment of the present invention will be specifically described with reference to the drawings. However, the embodiment described below is merely an example of the present invention and should not be construed as limiting the technical scope of the present invention. In each drawing, the same components are designated by the same reference numerals, and their description may be omitted.
[0020] [Overall layout of Desk 1] One of the features of the desk of this embodiment is that the legs at the front of the desk are shaped in a unique way so that the legs of adjacent desks do not interfere with each other and the stability of the desks is not compromised, even when multiple desks are arranged with their tops adjacent to each other.
[0021] In this specification, the upper and lower sides of the vertical direction when the desk 1 is placed in a usable state with the top board 2 facing up are referred to as "vertically above" and "vertically below," respectively, or simply as "above" and "below." The vertical direction is sometimes referred to as the "height direction." The right, left, front, and rear sides of the desk 1 relative to the position where the user sits or stands when in use are referred to simply as the right, left, front, and rear, respectively. The left-right direction is referred to as the "width direction," and the front-to-back direction is referred to as the "depth direction" or "depth," with the width direction and depth direction being perpendicular to the vertical direction. When the user sits or stands on the desk 1 when in use, this is sometimes referred to as "sitting at the desk." For convenience, the surface on which the desk 1 is placed is referred to as the floor.
[0022] 1 to 3 are diagrams showing a desk 1 of an embodiment, in which Fig. 1 is a perspective view, Fig. 2 is a side view, and Fig. 3 is a top view as viewed vertically from above. In the top view of Fig. 3, components located below the top board 2 are indicated by dashed lines.
[0023] Desk 1 comprises a tabletop 2, four legs 31 to 34, casters 41 and 42, and a back panel 5. Desk 1 can stand on its own using legs 31 to 34 and can be used alone, but multiple desks 1 can also be arranged with the edges of their tabletops 2 adjacent to each other as shown in Figure 4. Desk 1 can be suitably used as a seminar desk for seminars, etc.
[0024] [Tabletop 2] As shown in FIGS. 1 and 3, the tabletop 2 is a pentagonal plate-like member and has edges 21 to 25 corresponding to the five sides that form the pentagon. Edge 25 is located closest to a user sitting at desk 1 and extends linearly in the left-right direction relative to the user. Edges 23 and 24 extend linearly from the right and left ends of edge 25 toward the front, perpendicular to edge 25. Edges 21 and 22 extend from the front ends of edges 23 and 24 toward each other, forming obtuse angles with edges 23 and 24, respectively. The angle between edge 21 and edge 22 is 120°, and when multiple desks 1 are placed adjacent to each other so that edges 21 and 22 are in contact as shown in FIG. 4, they are arranged in a circle with no gaps between them.
[0025] The tabletop 2 can be tilted forward, which is the opposite side from where the user stands when using the desk. Specifically, the desk 1 has a shaft (not shown) that is connected to the legs 31 to 34 and extends parallel to the edge 25. The tabletop 2 is connected to this shaft so that it can rotate forward and backward, allowing the tabletop 2 to be tilted forward.
[0026] [Legs 31~34] The legs 31 to 34 are curved columnar or cylindrical members that support the tabletop 2 so that the top surface of the tabletop 2 forms a plane perpendicular to the vertical direction. A member 35 may be interposed between the legs 31 to 34 and the tabletop 2 (see FIG. 2). The leg 31 is the right front leg, the leg 32 is the left front leg, the leg 33 is the right rear leg, and the leg 34 is the left rear leg. The legs 31 to 34 may be collectively referred to simply as legs. The legs 31 and 32 may be referred to as front legs, and the legs 33 and 34 as rear legs.
[0027] As shown in FIG. 3, legs 31 to 34 are arranged to extend approximately parallel to one another. Legs 31 and 33 are connected to one another, with leg 33 located further outboard than leg 31 in the left-right direction. The position at which leg 31 contacts the floor is forward of the position at which leg 33 contacts the floor. Similarly, legs 32 and 34 are connected to one another, with leg 34 located further outboard than leg 32 in the left-right direction. The position at which leg 32 contacts the floor is forward of the position at which leg 34 contacts the floor. When viewed vertically from above, the distance between legs 31 and 32 is shorter than the distance between legs 33 and 34.
[0028] 3, when viewed from vertically above, legs 31 and 32 are arranged so that their lower portions protrude forward from edges 21 and 22, respectively, of tabletop 2. On the other hand, legs 33 and 34 are located below tabletop 2 when viewed from vertically above. Specifically, the contact portions of legs 33 and 34 that come into contact with the floor are located immediately in front of edge 25 when viewed from vertically above.
[0029] 1 to 3, leg 31 has portion 311 extending linearly in the vertical direction from the contact portion with the floor, bent portion 312 bending backward, portion 313 extending linearly rearward and upward, bent portion 314 bending upward, portion 315 extending linearly rearward and upward, and upper end 316. Portion 315 has a steeper slope than portion 313.
[0030] Like leg 31, leg 32 has a portion 321 extending vertically in a straight line from the contact point with the floor, a bent portion 322 bending backward, a portion 323 extending linearly backward and upward, a bent portion 324 bending upward, a portion 325 extending linearly backward and upward, and an upper end 326. Portion 325 has a steeper slope than portion 323.
[0031] Comparing leg portion 31 and leg portion 32, bent portions 312, 314, 322, and 324 are bent portions 312, 322, 314, and 324 in order from the lowest position.
[0032] FIG. 4 is a perspective view of three desks 1, 1a, and 1b arranged so that their tabletops 2 are adjacent to each other. The desks 1, 1a, and 1b are all identical in shape, and the symbol "X" on desk 1 is "Xa" on desk 1a and "Xb" on desk 1b, with the suffixes a and b added, and "X," "Xa," and "Xb" indicate the same components. Explanations of such "Xa" and "Xb" may be omitted.
[0033] In FIG. 4, the edges 21, 21a and 21b of the desks 1, 1a and 1b are arranged adjacent to the edges 22a, 22b and 22b of the adjacent desks 1a, 1b and 1b, respectively.
[0034] FIG. 5 is a cross-sectional view of FIG. 4 taken along a plane extending vertically from a line EE along the edge 22 of the desk 1 in FIG. 4. As shown in FIGS. 4 and 5, the adjacent desks 1 and 1b are arranged so that the leg 32 of desk 1 intersects with the leg 31b of desk 1b when viewed vertically from above. As shown in FIG. 5, at the position where the leg 32 of desk 1 intersects with the leg 31b of desk 1b when viewed vertically from above, the leg 32 of desk 1 is located above the leg 31b of desk 1b. In other words, the cross-sectional area 329 of the leg 32 of desk 1 and the cross-sectional area 319b of the leg 31b of desk 1b are at different heights in a plane extending vertically from the line EE so as not to overlap each other. This allows the desks 1 and 1b to be arranged adjacent to each other without interference between the leg 32 and the leg 31b. The same applies to desk 1 and desk 1a, and desk 1a and desk 1b.
[0035] When viewed from the perspective of the desk 1 alone, the configuration of the desk 1 is as follows. As shown in FIG. 3, if the point where a line A along edge 21 intersects with a line B along edge 22 is defined as the top C, a region AX (not shown) is defined where the leg 31 passes through a plane containing line A and the vertical direction, and a region BX (not shown) is defined where the leg 32 passes through a plane containing line B and the vertical direction. Region CX (not shown) is created by moving region AX symmetrically with respect to a plane containing the top bisector D and the vertical direction, and does not overlap with region BX. More specifically, regions CX and BX are offset in the height direction. Regions BX and CX have the same relationship as cross-sectional region 319b and cross-sectional region 329 in FIG. 5. When viewed vertically from above, legs 31 and 32 are symmetric with respect to bisector D.
[0036] As shown in Figures 1 to 3, leg 33 has portion 331 extending linearly in the vertical direction from the contact point with the floor, bent portion 332, portion 333 extending linearly forward and upward, bent portion 334, portion 335 extending linearly backward and upward, and upper end 336.
[0037] Like leg 33, leg 34 has a portion 341 extending linearly in the vertical direction from the contact point with the floor, a bent portion 342, a portion 343 extending linearly forward and upward, a bent portion 344, a portion 345 extending linearly backward and upward, and an upper end 346. Leg 33 and leg 34 are formed symmetrically with respect to a plane containing bisector D and the vertical direction. Components 33x of leg 33 and components 34x of leg 34 that share the same x are corresponding components.
[0038] [Casters 41 and 42] Casters 41 and 42 are attached to the lower ends of the legs 31 and 32, respectively. On the other hand, no casters are attached to the legs 33 and 34.
[0039] In this way, by attaching casters 41 and 42 to legs 31 and 32 located at the front, when moving desk 1, desk 1 can be easily moved by lifting the front side (rear) of the desk to raise legs 33 and 34 off the floor and then turning casters 41 and 42. Furthermore, since casters are not attached to legs 33 and 34, desk 1 can be made less likely to shift unexpectedly by bringing legs 33 and 34 into contact with the floor.
[0040] [Curtain Panel 5] The back panel 5 is a panel-like member that extends substantially vertically downward and parallel to the edge 25. The back panel 5 is provided so as to hide part of the feet of a user sitting at the desk 1.
[0041] [Variations] The desk of the present invention is not limited to the configuration of the desk 1 in the above embodiment, and various modifications are possible without departing from the spirit of the invention. Modifications are shown below, but the modifications are not limited to these.
[0042] In the case of desk 1, the angle between edges 21 and 22 of table top 2 is 120°, and three desks 1 can be arranged adjacent to each other in a circle without any gaps, but it is preferable to set this angle to a divisor of 360°, such as 90°, 72°, or 60°. In this way, by arranging a predetermined number of desks 1 adjacent to each other, they can be arranged in a circle without any gaps. However, the shape is not limited to this.
[0043] The desk 1 may be configured so that the tops of edges 21 and 22 are cut parallel to edge 25 to form a hexagonal shape. In this case, the desk 1 may be configured so that a hole-like portion is formed in the center of the desk 1 arranged in a circle.
[0044] The table top 2 may have a shape like table top 2c shown in Fig. 6 or a shape like table top 2d shown in Fig. 7. That is, one edge 21c (21d) at the front of the desk 1 and the other edge 22c (22d) may be shaped so that they can be adjacent to each other while complementing each other's spaces. The shape of the table top 2 is not limited to these specific examples, and other shapes that satisfy the spirit of the invention may be used.
[0045] As can be understood from the gist of the present invention, desk 1 is characterized in that legs 31 and 32, which are provided to protrude forward from front edges 21 and 22, respectively, when viewed from above, are offset in the height direction so as not to interfere with each other. Therefore, regardless of the shape of the embodiment, it may be modified to have a shape with the same gist.
[0046] The desks 1 do not necessarily need to be placed adjacent to each other so that the edges 21 and 22 of the table tops 2 abut each other; they may be configured so that their edges 25 form a predetermined angle, but are spaced apart and close together to maintain their positions. For example, the positions of adjacently placed desks 1 may be maintained by an abutting portion instead of the table top 2, or some other configuration may be used. Even in this case, the object of the present invention is achieved as long as, when desk 1 and another desk 1 are placed adjacent to each other, the front legs 31 and 32 intersect when viewed vertically from above, but are at different height positions so as not to interfere with each other.
[0047] In the desk 1, casters 41 and 42 are attached to the legs 31 and 32, but no casters are attached to the legs 33 and 34, but the configuration is not limited to this. For example, casters may be attached to all of the legs 31 to 34, or casters may be attached to the legs 33 and 34, but no casters may be attached to the legs 31 and 32. Alternatively, casters may be attached to all of the legs 31 to 34, and stoppers may be provided on the legs 33 and 34 to restrict the movement of the casters.
[0048] The edges 23 and 24 of the top plate 2 do not need to extend perpendicular to the edge 25 when viewed vertically from above, but may extend in a predetermined direction.
[0049] [Summary of the embodiment and modifications] As described above, desk 1 has legs 31 and 32 that protrude from edges 21 and 22 of tabletop 2 when viewed vertically from above. When desk 1 is configured such that top C is the point where line A, which is a line connecting both ends of edge 21, and line B, which is a line connecting both ends of edge 22, intersect, area (AX) where leg 31 passes through a plane containing line A and the vertical direction is moved symmetrically with respect to a plane containing bisector D of top C and the vertical direction to form area (CX), and area (BX) where leg 32 passes through a plane containing second line B and the vertical direction do not overlap each other.
[0050] With this configuration, when multiple (for example, three) desks 1 are arranged with their edges adjacent to each other around the top C, the legs of adjacent desks 1 do not interfere with each other. In this case, the legs of the desks 1 can be arranged so that they cross when viewed vertically from above, so that the fulcrums of the desks 1 can be arranged over a wide area, making the desks 1 stable.
[0051] Furthermore, in desk 1, legs 31 and 32 are arranged symmetrically with respect to bisector D of top C when viewed vertically from above, and the above-mentioned areas (CX) and (BX) do not overlap in the height direction. As a result, simply by bending legs 31 and 32 at different heights, legs 31 and 32 can be arranged not to interfere with each other when desks 1 are placed adjacent to each other as described above.
[0052] In addition, in desk 1, leg 31 includes portion 311 extending vertically upward from the contact portion with the floor, bent portion 312 bent at a first height, portion 313 extending from bent portion 312, bent portion 314 bent at a second height higher than the first height, and is directly or indirectly connected to tabletop 2 above portion 315 extending from bent portion 314. Leg 32 includes portion 321 extending vertically upward from the contact portion with the floor, bent portion 322 bent at a third height, portion 323 extending from bent portion 322, bent portion 324 bent at a fourth height higher than the third height, and is directly or indirectly connected to tabletop 2 above portion 325 extending from bent portion 324. In this case, the third height is between the first height and the second height, and the fourth height is higher than the third height. Furthermore, the leg 31 is configured to be located on the right side of the desk 1 when viewed from the position where the user sits or stands when in use.
[0053] With this configuration, when multiple desks 1 are arranged adjacent to one another, the left front leg 32 of one desk 1 is inserted into the back side of the leg 31 of the desk 1 arranged to the left of this desk 1. On the other hand, the right front leg 31 of one desk 1 is placed in front of the leg 32 of the desk 1 arranged to the right. By making this type of arrangement possible, the configuration is easier to arrange than an arrangement in which the left and right are reversed.
[0054] Furthermore, the desk 1 is configured such that casters 41 and 42 are attached to the legs 31 and 32, but no casters are attached to the legs 33 and 34. With this configuration, the desk 1 can be easily moved by lifting the front side of the desk 1, i.e., the edge 25 side. Furthermore, if the legs 33 and 34 are in contact with the floor after the desk 1 is set up, the desk 1 is less likely to shift position.
[0055] Furthermore, in desk 1, top board 2 can be rotated to tilt forward, and legs 31 to 34 extend substantially parallel to one another when viewed vertically from above, with the distance between legs 31 and 32 being shorter than the distance between legs 33 and 34. This allows desk 1 to be configured to be stored in a space-saving manner.
[0056] Furthermore, when the desk 1 is placed close to another desk 1 at a predetermined angle, when viewed from above vertically, the legs 31 of the desk 1 and the legs 32 of the other desk 1 intersect at a predetermined intersection position, and at this intersection position, the heights of the legs 31 and 32 may be different. With this configuration, the legs of the desk 1 and the other desk 1 placed close to each other do not interfere with each other. [Explanation of symbols]
