Description

  The present invention relates to a desk system (which may be called a desk device) formed by combining a plurality of desks (unit desks) and a single desk used for the desk system.

  In recent years, various forms have been proposed for desks (desk devices). As an example, there is one in which the top plate is formed in an L shape in plan view. This desk is easy to use because, for example, it can perform tasks such as writing and reading, and operations such as personal computer operations and word processor operations in different areas. In a desk having this L-shaped top plate, a back panel for blindfolding or shelf support is generally fixed on the back. In addition, a desk device in which an L-shaped top plate is attached to the partition is also frequently used. In a conventional desk with an L-shaped top plate, the top plate is composed of a single plate or two.

  On the other hand, Patent Document 1 discloses a desk device that is L-shaped as a whole by disposing an auxiliary desk on the side of the main desk. In this desk apparatus, the top plate of the auxiliary desk is the main desk. The top plate of the auxiliary desk is provided with two front and rear bar-shaped legs.

  In addition, a desk system that combines a plurality of desks has been developed, and as one of them, the applicant of the present application in Japanese Patent Application Laid-Open No. 2004-228561 uses a left brain-like work and a right brain by using a person with different work positions and postures. We proposed a desk system that can select the environment suitable for each of the general work and the intermediate work.

In other words, this desk system has three top plates, a top plate that performs left-brain work, a top plate that performs right-brain work, and a top plate that performs intermediate work, and a rear panel behind each top plate. The elements that can be visually grasped such as the color, material, texture, and shape of each back panel are selected to be suitable for the work contents.
JP-A-5-329025 JP 2003-82871 A

  By the way, the user's request for the desk varies depending on the preference, the problem of the installation location, etc., for example, there is a request to use two desks arranged side by side or a plan view L-shaped form. . However, a desk (and a desk device) having a conventional L-shaped (or U-shaped) top plate has no change in the form of the desk, and the user cannot change the plane form of the desk.

  On the other hand, Patent Document 2 can change the plane form of the desk device, but the auxiliary desk cannot be used independently because it cannot be detached when it is removed from the main desk. Therefore, it responds to various requests of users. It is hard to say that you get.

  As a countermeasure for these points, a plurality of rectangular desks in plan view are prepared and arranged side by side in a horizontally long row, or the side end of the other desk is brought into contact with the front of one desk in plan view L. It can be considered that the layout is left to the user's selection, such as being arranged in a letter (or U-shape), and further being arranged apart from each other. However, in this case, there arises a problem that the legs interfere with the user when arranged in an L shape or a U shape.

  In other words, the desk includes a leg that supports the top plate, and as one form of this leg, a horizontal heel extends forward from the lower end of the column portion that is positioned near the rear of the top plate and extends vertically. There is an L-shaped “L leg” in the form of a desk in which the desk is arranged in an L shape or U shape in plan view so that it does not interfere with a person's foot when seated (especially when moving). Will adopt this L-leg, but if the desk is placed in an L shape in plan view, the horizontal heel of the leg located at the location of the abutting portion of both desks will extend long from the support to the front. This horizontal ridge is in the way.

  It is an object of the present invention to provide a user-friendly desk and desk unit that are easy to use while being a desk unit with a high degree of freedom in layout selection.

  The invention of claim 1 relates to a desk system, and this desk system has, as a basic configuration, at least two desks formed by supporting one end of the top plate and the other end of the top board with legs. These two desks can be used independently and have an L-shaped or T-shaped posture in plan view where one side edge of the top plate of the other desk is applied to the front end surface of the top plate of one desk The top plate of both desks can be connected by a connecting tool in use in the L-shaped or T-shaped plan view.

  One of the left and right legs of the other desk that supports one end of the top plate is provided with a support column that is positioned near the rear of the top plate and extends vertically. On the end face, a long horizontal rod extending long from the front side of the support column to the front side, and a short horizontal rod having a front-rear length equal to the front-rear width of the support column or a small forward projecting dimension from the support column. Can be selected and fastened with bolts.

  According to a second aspect of the present invention, in the first aspect of the present invention, the connecting tool is also used as a long horizontal rod, and the two desks are flattened by fastening a short horizontal rod to a support portion of one leg of the other desk. In a state of being arranged in the L-shape or T-shape, the long horizontal rod can be arranged so as to straddle the lower surfaces of the top plates of both desks and can be fixed to both the top plates with bolts.

  The invention of claim 3 has at least two desks each having one end and the other end of the top plate supported by legs, and these two desks are used independently. And a desk system that can be used by connecting the top plates of one desk and the other desk to each other. In this desk system, at least one leg of each leg of the both desks Is a long horizontal ridge that extends from the front side of the support column to the front side, and a front-rear length that is the same as the front-rear width of the support column. It is possible to select a horizontal rod having a short length and to be fastened with a bolt, and to connect the top plates with a horizontal rod that is not fixed to the lower surface of the support column.

  The present invention also includes a single desk that constitutes the desk system according to claim 2 or 3, and this desk has a short horizontal hook in a state where a long horizontal hook is fastened to the support column. It is attached to the top plate and other members constituting the desk. In this aspect, it is preferable that the short horizontal rod is attached to a portion that does not interfere with the use or packing of the desk, such as the lower surface of the top plate, the inner surface (front surface) of the curtain plate, or the inner surface of the leg.

  According to the invention of claim 1, in using two desks in a plan view L-shaped or T-shaped, by using a short one as the horizontal rods of the legs located at the contact portion of both desks, It is possible to prevent the legs from interfering with the user and ensure usability, and the top plates of both desks are connected by a connecting tool, so that the stability of the top board of the other desk can be ensured. In addition, when the other desk is used independently, it is possible to maintain stability by using a horizontal rod having a long length for both the left and right legs.

  Therefore, according to the first aspect of the present invention, the two desks can be arranged in an L shape or a T shape without impairing the freedom of layout selection, such as arranging the two desks in an L shape or a T shape, or arranging them on the left and right sides or separating them. It is possible to ensure the ease of use and stability in the arranged state.

  Although it is possible to provide a dedicated member for the connector, if it is configured as in claim 2 and claim 4, the horizontal rod can be used also as the connector, so that the number of members can be suppressed and the cost can be suppressed. is there. Moreover, when comprised like Claim 4, there is also an advantage which can prevent the loss of the short horizontal ridge when using the other desk alone.

  There are cases where two desks are arranged side by side to connect the top plates to each other. However, when configured as in claim 3, the horizontal plates of the legs can also be used as a connecting tool in connecting the top plates in this way. Therefore, like the second and fourth aspects, there is an advantage that the number of members can be suppressed without impairing the freedom of layout. Also in the invention of claim 3, it is possible to place the desks in an L shape or T shape in plan view and connect the top plates to each other with a horizontal gutter.

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

(1). Outline of First Embodiment FIGS. 1 to 6 show a first embodiment, in which FIG. 1 is an overall schematic perspective view, FIG. 2 is an overall plan view, and FIG. 3 is an overall front view. FIG. First, an outline of the desk system will be described based on these drawings. The desk system of this embodiment is designed mainly assuming that it is used by children (students can also use adults).

  The desk system of the present embodiment includes a first desk 1 (one desk) suitable for left brain work such as calculation, and a third desk 3 suitable for right brain work such as assembly of a plastic model and work work. And a second desk 2 (the other desk) suitable for an intermediate work between the left brain work and the right brain work like the operation of the personal computer P. Each of the desks 1, 2, and 3 includes top plates 4, 5, and 6, and the first desk 1 and the second desk 2 are arranged in an L shape in plan view.

  Therefore, the desk system as a whole has a U-shaped posture in plan view, and a chair C with casters is arranged in a space surrounded by each desk. The user can use each desk 1, 2, 3 arbitrarily by changing the posture and position.

  In the following description, for the sake of convenience, the top 4 of the first desk 1 is the first top 4, the top 5 of the second desk 2 is the second top 5, and the top 6 of the third desk 3 is This is called the third top plate 6. In addition, for the sake of convenience in this specification, the words “left, right, front, and rear” are used, but these words are based on a user who is in a posture (use state) facing the top board (therefore, accordingly). The left and right sides of the first machine 1 and the third machine 3 are reversed.)

  When a sleeve drawer (wagon) is provided in the desk system, it may be arranged below any one of the top plates 4, 5, 6 or outside the first desk 1 or the third desk 3.

  The first top plate 4 and the third top plate 6 are horizontally long and rectangular in plan view. On the other hand, the second top plate 5 has a shape close to a horizontally long rectangle, but the front end surface is gently curved in a forward projection in plan view. It has become. The right side end (one side end) of the second top plate 5 is in contact with the front surface of the first top plate 4, and the left side surface of the first top plate 4 and the back surface of the second top plate 5 are straight lines. It extends in a shape.

  In this embodiment, it is the structure which stuck the melamine resin layer on the surface of the wooden board with the 1st top plate 4 and the 2nd top plate 5, for example, it is achromatic | colorless and calm with high brightness, such as white and light gray Adopting different colors. On the other hand, the 3rd top plate 6 is a wooden board, and the grain is still appearing. Although the height of each top plate 4, 5, 6 can be adjusted to a plurality of levels (details will be described later), the first top plate 4 and the second top plate 4 are arranged in a state where the top plates 4, 5, 6 are positioned at the top level. The height is the same as the top plate 5, and the third top plate 6 is set to be lower than the first top plate 4 and the second top plate 5. For this reason, the 3rd top plate 6 can be pushed below the 2nd top plate 5 (and the 1st top plate 4).

  The left and right sides of each top plate 4, 5, 6 are supported by legs 7. Each leg 7 includes a plate-like columnar portion 8 in which a grain appears and a metal horizontal rod 10 fastened with a bolt 9 to the lower end surface thereof. As can be understood from FIG. 2, the horizontal rod 10 of the right leg 7 in the second desk 2 has a short length almost the same as the front-rear width dimension of the column portion 8, and the horizontal rod 10 in the other legs 7 is the column portion. It has a long length extending greatly from 8 to the front.

  The reason why the horizontal rod 10 extends long forward from the support column 8 is to ensure the stability of the desk, and on the other hand, the horizontal rod 10 of the right leg 7 in the second desk 2 is short because the user in the seated state (In particular, to avoid interference when moving or changing the posture of the first desk 1 and the second desk 2).

  In order to avoid the deterioration of the stability of the second desk 2 due to the shortening of the horizontal rod 10 of the right leg 7 of the second desk 2, the first top board 4 and the second top board 5 are provided on the lower surfaces of both. It connects with the connecting tool 11 extended over (it mentions later for details).

  The horizontal cage 10 of the third desk 3 is provided with a pair of front and rear casters 12. For this reason, the position and posture of the third desk 3 can be easily changed by the user pushing and pulling. With the casters 12 in contact with the floor, the horizontal bar 10 of the third desk 3 is set to be higher than the horizontal bar 10 of the second desk 2 (and the first desk 1). Therefore, the third desk 3 can partially enter the internal space of the second desk 2.

  The front-rear width dimension of each support column 8 is about half the front-rear width of the top plates 4, 5, 6, and the outward opening in which the support column 8 fits in the rear half of each top plate 4, 5, 6. Therefore, the outer surface of the support column 8 and the left and right end surfaces of the top plates 4, 5, 6 are on the same plane. The support column 8 and the back surfaces of the top plates 4, 5, 6 are on the same plane.

  Each of the desks 1, 2, 3 includes main partitions (back panels) 14, 15, 16 fixed to the backs of the top plates 4, 5, 6. The main partitions 14 and 15 of the first desk 1 and the second desk 2 extend over substantially the entire width of the top plates 4 and 5, and also extend below the top plates 4 and 5. On the other hand, the main partition 16 of the third desk 3 has a portion located below the top plate 6 having the same length as the third top plate 6, but the portion exposed upward from the top plate 6 is biased to the left side. Therefore, in the third desk 3, a substantial part on the right side of the desk space is open. The main partition 16 of the third desk 3 is made of wood board with exposed grain.

  Since the right end surface of the second top plate 5 is brought into contact with the front end surface of the first table top plate 4, the main partition 14, 15 of the first table 1 and the second table 2 has a space between the first table 1 and the first table 1. The space of the space | interval of the width dimension of the top plate 4 is vacant. A sub-partitioning body 17 that partitions all or most of the space is attached to the main partitioning body 14 of the first desk 1.

  A shelf 18 and hangers 19 as optional items can be detachably suspended from the main partitions 13, 14, 15. A notch 20 for pulling out a cable such as a power source is formed in the left and right intermediate portions of the back surface of each top plate 4, 5, 6, and a clamp-fixed lamp 21 is formed using this notch 20. It can be installed.

(2). Top plate, leg and main partition Next, the fixing structure of the top plates 4, 5, 6 and the leg 7 will be described with reference to FIG. FIG. 4 is an exploded perspective view showing the relationship between the first top plate 4 and the legs 7.

  As can be understood from FIG. 4, the support column 8 and the first top plate 4 are fixed through a block-like reinforcing material (bracket) 23 made of wood. The reinforcing member 23 has substantially the same length in the front-rear direction as the support column 8 and is fixed to the lower surfaces of the left and right side portions of the first top plate 4 by dowel pins 24 and screws 25 so as not to be separated. It is fastened to the support column 8 by two front and rear screws 26 penetrating the portion 8 from the outside.

  In this case, a plurality of pairs of mounting holes 27 of screws 26 are formed in the support column 8 at appropriate intervals (six stages in the figure), while the reinforcing member 23 has a demon nut 28 into which the screws 26 are screwed. A pair with the pin hole 29 is provided so as to be vertically separated. The vertical distance between the demon nut 28 and the pin hole 29 ′ is the same as the distance between the mounting holes 26, and the positioning pins 29 are inserted into the pin holes 29 ′ and the mounting holes 26.

  The fixing structure of the second top plate 5 and the legs 7 is exactly the same as that of the first desk 1. The fixing structure of the third top plate 6 and the legs 7 is basically the same as that of the first tooth desk 1, but the third desk 3 may be subjected to a greater load, for example, during work. It extends to the vicinity of the front end of the third top plate 6 and two positioning pins are provided on the top and bottom. Each reinforcing material 23 may be made of metal.

  The main partitions 14 and 15 of the first desk 1 and the second desk 2 have a structure in which a skin material 31 made of cloth or the like is wound around a frame 30 formed of square steel pipes in a square shape in front view. It is fastened to the back surface of the column 8 so that the height can be adjusted. Although not shown, the skin material 31 is held in a cylindrical shape by a fastener, and can be easily attached to and detached from the frame 30 by opening and closing the fastener.

  The skin material 31 of the main partition 14 in the first desk 1 adopts a cold chromatic color such as green or blue, for example. This is for realizing a visual environment suitable for left-right work. On the other hand, the skin material 31 of the main partition 15 in the second desk 2 employs an achromatic color such as white or light gray and a high brightness.

  The sub-partitioning body 17 has a configuration in which a cloth partition curtain 34 is suspended from a horizontally long hanger (bar) 33, and is fastened to the frame 30 by screws at the base end of the hanger 33 via a bracket. The partition curtain 34 has the same color and the same material as the skin material 31 of the first main partition 14. Both the first top plate 4 and the second top plate 5 are white-colored (light amber) achromatic colors.

(2). Connection of Desk Next, a connection structure between the first top plate 4 and the second top plate 5 will be described with reference to FIGS. 5 is a cross-sectional view taken along the line VV in FIG. 2, FIG. 6A is a perspective view when the second desk 2 is used alone, FIG. 5B is a cross-sectional view taken along the line BB in FIG. ) Is a cross-sectional view taken along the line CC of (A).

  As described above, the first top plate 4 and the second top plate 5 are connected by the connecting tool 11, but in this embodiment, the leg when the second desk 2 is used alone as the connecting tool 11. 7 horizontal rods 10 are used.

  That is, as shown in FIG. 6 (A), when the second desk 2 is used alone, the left and right legs 7 use the long horizontal rods 10, and for this reason, the right side of the second desk 2 is used. There are two types of legs 7, a long horizontal rod 10 and a short horizontal rod 10. When the first desk 1 and the second desk 2 are arranged in an L shape in plan view, the length of the leg 7 is long. Both top plates 4 and 5 are connected using a long horizontal rod 10.

  The horizontal rod 10 is formed in an oblong cross-sectional oblong shape, and has two front and rear (or three or more) bolt holes 36 for fixing it to the support column 8, and the head of the bolt 9 is hollow. Hidden inside the club. A demon nut 35 into which the bolt 9 is screwed is embedded in the support column 7. Then, when the first top plate 4 and the second top plate 5 are abutted with each other, the demon nuts 37 are embedded at the same interval as the interval L between the bolt holes 36, so that the horizontal rod 10 is fixed to the both top plates 4, 4. 5 is fastened with a bolt 38.

  When the second desk 2 is used alone (in an unconnected state), the short horizontal rod 10 is fixed to the lower surface of the second top plate 2. For this reason, two demon nuts 37 are embedded in the second top plate 5. The demon nut 37 is an example of a screw hole, and can be fixed with a wood screw.

  Although it is possible to use a dedicated member as the connector 11, if the horizontal rod 10 is used as in the present embodiment, it is possible to use what is originally required as a component of the leg 7, so the number of members can be increased. There is an advantage that can be suppressed. It is also possible to connect with a plurality of connectors of the horizontal rod 10 and the dedicated member.

(3). Other embodiment (FIGS. 7 to 8)
7 and 8 show another embodiment. In the second embodiment shown in FIG. 7 (A), the front-rear width dimension of the support column 8 is about 1/3 of the front-rear width dimension of the top plate 39. It extends to the near side. As can be seen from this, the horizontal rod 10 having a short length need only be a length that does not interfere with the user's work or movement while sitting, and is not necessarily the same as the front-rear width dimension of the support column 8. Need not be.

  In the third embodiment shown in FIG. 7B, the support column 8 is formed in a frame shape by the front and rear main rods 7a and the horizontal rods 7b connecting the lower ends thereof. Thus, the form and structure of the support | pillar part 8 can be set as needed.

  FIG. 8 shows a third embodiment in which two desks 1 and 2 can be used by connecting them in a T-shape in plan view. (A) is a top view, (B) is a BB view sectional view of (A).

  The desk system of this embodiment is composed of a first desk 1 that is long and narrow, and a second desk 2 that is wide and short. The long horizontal rod 10 is arranged at the front and rear intermediate portion and extends to both the front and rear sides of the column portion 8. The horizontal rod 10 having a short length is set to be the same as the front-rear width of the support column 8. The top panels 4 and 5 are each provided with a desktop panel 39 that divides the desktop space into two parts, and two people use the desk panel 42 on both sides.

  Although it can be easily guessed from this embodiment, it is possible to arrange three desks in an H shape in plan view, but in this case, there are two T-shaped connections symmetrically.

(4). Others Although not shown, in the present invention, it is possible to arrange two top plates on the left and right sides and connect the top plates in contact with each other. In this case, generally, the left and right desks have a long horizontal rod fixed to a support column, and the top plate is connected with a short horizontal rod.

  In addition, the shape of the top plate, the shape of the legs, etc. can be freely changed according to the design needs. Needless to say, the main partition and the sub-partition are not required. When arranging three desks in a U-shape in plan view, it is sufficient to prepare two horizontal rods for the left and right legs on the desk located in the center.

It is a figure which shows 1st Embodiment, (A) is a schematic perspective view of the whole, (B) is a partial top view. It is the whole top view. It is the whole front view. It is an isolation | separation perspective view which shows the relationship between a top plate and a leg. FIG. 5 is a cross-sectional view taken along the line V-V in FIG. 2. (A) is a perspective view when the second desk is used alone, (B) is a cross-sectional view taken along the line B-B, and (C) is a cross-sectional view taken along the line C-C of (A). It is a side view of 2nd Embodiment and 3rd Embodiment. It is a figure which shows 4th Embodiment, (A) is a top view, (B) is BB sectional drawing of (A).
