Description

The present invention relates to a combination desk that uses a combination of a desk and a bookshelf, and more particularly, to a combination desk device that can combine the desk and the bookshelf in various systems according to ease of use.

There is a bookshelf that organizes and stores books, reference books, textbooks, etc. used for learning in order to improve learning efficiency and usability on desks used in study rooms at home and offices such as study. , May be placed close to the desk. For this reason, there are conventional desks in which a desk and a bookshelf are made independent and a book shelf is placed behind the desk, and a combination desk in which a book shelf is placed on the side of the desk and the desk and the book shelf are combined in an L-shaped system.
In this way, in the system where the bookshelf is arranged in an L shape so that the longitudinal direction of the bookshelf is perpendicular to the desk on the side of the desk, the takeout opening of the bookshelf faces the direction of the chair placed when using the desk , The chair may get in the way and the bookcase may be difficult to use. In addition, since the direction of the entrance and exit of the bookshelf is constant, the arrangement method of the combination desk in the room may be limited. For this reason, there are some which are configured so that the direction of the entrance / exit of the bookshelf can be changed.

  For example, in Patent Document 1, a side plate and a curtain plate are arranged in an L shape on the side of a storage shelf, a top plate and a bottom plate are provided, an opening surface in which two adjacent surfaces open is provided, A storage shelf is described in which a rotating shelf is provided so as to be rotatable with respect to the main body between the bottom plate. On the other hand, in Patent Document 2, a rotating shelf provided rotatably on a main body is provided so as to be rotatable about a vertical rotation axis, and a top plate provided on a pair of side frames and upper ends of the side plates, and a lower end of the side plates. There is described a storage shelf that is formed in a rectangular parallelepiped shape with a bottom plate provided on the inner side of the rotating shelf so that an article can be stored between the side frames through an opening between the pair of side frames. And from the 5th line of specification (5) of patent documents 2, it can be used in the state where the rotation shelf was located in the opening side of the front of the main part or the opening side of the other (back). From the second line of the specification (6) of Patent Document 2, it is described that the rotation shelf is provided with a rotation stopper that holds the rotation shelf at each opening side surface.

And the storage shelf comprised by the combination of the structure of the said storage shelf of patent document 1 and the structure of the said storage shelf of patent document 2 is disclosed by patent document 3. FIG.

However, in the case of a rotating shelf such as Patent Document 1 and Patent Document 2, a storage space is reduced because a rotating space of the rotating shelf is required as compared with a fixed shelf type. For example, in the case of a square rotating shelf, it is necessary to provide a space between the rotating shelf and the side plate and back plate of the storage body for the rotation trajectory drawn by the square corners. In the case of a circular rotating shelf, the space is not necessary, but the storage space of the shelf itself is reduced compared to a square. As described above, in the case of a rotating shelf such as Patent Literature 1 and Patent Literature 2, there is a problem that the usability as a storage shelf is deteriorated in a combination desk installed in a limited space. In addition, in the case of a rotating shelf as in Patent Document 3, it is necessary to take out the stored items and remove the shelf board every time the rotating shelf is rotated, which causes a problem that the rotating operation is cumbersome and unusable.

Japanese Utility Model Publication No. 06-033529 Japanese Utility Model Publication No. 62-182039 Utility Model Registration No. 3205745

 In view of such problems, the present invention has an object to provide a combination desk device that can combine a desk and a bookshelf into various systems according to usability with a simple configuration and easy work. To do.

  Therefore, in order to solve the above-mentioned problems, the present invention is configured as a first means, a desk configured by providing a top plate on at least the upper part of a pair of legs, and a frontage size substantially equal to the frontage size of the desk. In the combination desk composed of bookcases set in the bookcase, the bookcase has a top and bottom plates, a large storage portion and a small storage portion that are arranged between the top and bottom plates in the left and right direction in the frontage direction. Is a rectangular shape that is long in the frontage direction in a plan view, and at least one side of the long sides of the rectangle is an opening that serves as a storage port, and the small storage portion has a substantially square shape in a plan view. In addition, at least one side of the four sides forming the substantially square is an opening that serves as an inlet / outlet of the storage portion, and the small storage portion is rotatable between the top plate and the bottom plate about a vertical rotation axis. The vertical rotation axis position of the bookcase The small storage portion can be temporarily moved in the outward direction on the storage portion side, and the small storage portion can be rotated at the position where the vertical rotation shaft is temporarily moved, and the opening of the small storage portion has an opening that faces the front of the bookcase. The first system that faces, the second system that the opening faces the outer side of the bookshelf, and the third system that the opening faces the back of the bookshelf can be selected, and in the usage state in each system The small storage portion and the large storage portion are adjacent to each other.

  Next, in order to solve the above-mentioned problem, the present invention is configured as the second means. In addition to the configuration as the first means, the vertical rotation axis position of the small storage portion is determined from the usage state of the small storage portion. The book shelf can be temporarily moved to the outer front side obliquely on the small storage portion side.

  Next, in order to solve the above-mentioned problem, the present invention is configured as the third means, in addition to the configuration as the second means, the vertical rotation axis position of the small storage portion is determined from the usage state of the small storage portion, The book shelf can be temporarily moved to the rear obliquely outer side on the small storage portion side.

According to the configuration as the first means, the small storage portion that can be rotated can be rotated at a position moved outward from the use state at the time of rotation. Therefore, the small storage portion has a rectangular parallelepiped shape and is in a use state. Even when the small storage portion and the large storage portion are arranged adjacent to each other, the rectangular parallelepiped corner portion of the small storage portion does not contact the large storage portion when the small storage portion rotates. Therefore, the storage space with respect to the bookcase frontage dimension can be increased. Moreover, since it is not necessary to remove a shelf board at the time of rotation, rotation work is easy.
Since the opening of the small storage portion can be selected from the first system that faces the front of the bookcase, the second system that the opening faces the outer surface, and the third system that the opening faces the back surface. The combination pattern of desks and bookcases can be varied, and a combination of desks and bookcases that are easy to use is possible according to the layout of the room where the combination desks are installed.

  According to the configuration as the second means, in addition to the effect of the first means, the direction of temporarily moving the small storage portion in the outer side of the small storage portion side of the bookcase at the vertical rotation axis position of the small storage portion is Since it is set to be obliquely forward and outward from the use state, the small storage portion can be protruded obliquely forward and outward from the use state when the small storage portion is rotated. Therefore, even when the book shelf is installed along the wall on the back side of the book shelf, the small storage unit can be rotated without moving the entire book shelf.

According to the configuration of the third means, in addition to the effect of the second means, the direction of temporarily moving the small storage portion in the direction of the outer side of the small storage portion on the side of the small storage portion of the vertical rotation axis position of the small storage portion is changed. Since it is set to be obliquely rearward and outward from the use state, the small storage portion can be protruded obliquely rearward and outward from the use state when the small storage portion is rotated. Therefore, even when a desk is installed on the front side of the bookshelf, the small storage unit can be rotated without moving the entire bookshelf.
In addition, since the small storage part side can be protruded diagonally forward outside and rear outside from the use state, the back plate forming the large storage part of the book shelf is moved to the front side, and the book shelf is moved in the vertical direction. When rotated 180 degrees as the rotation axis, the right and left direction of the bookshelf 3 can be reversed, and the above-described effect can be obtained even in the reversed state. Therefore, there is no need to set the right and left bookshelves.

  In a combination desk composed of a desk configured with a top plate on top of a pair of legs and a book shelf set to a frontage dimension substantially equal to the frontage dimension of the desk, the bookshelf, the top board and the bottom plate, A large storage part and a small storage part that are arranged between the top and bottom plates in the left and right direction of the frontage. The large storage part is a long rectangle in the frontage direction and one side of the long sides of the rectangle in plan view. And the small storage portion is formed into a substantially square shape in plan view, and one side of the four sides forming the substantially square shape is set as an opening portion with the storage portion access port, A direction in which the small storage portion can be rotated between the top plate and the bottom plate around the vertical rotation axis, and the vertical rotation shaft position can be temporarily moved outwardly on the small storage portion side of the bookcase From the usage state of the small storage part to the diagonally forward outer side or diagonally rearward outer side The small storage portion can be rotated at a position where the linear rotation shaft is temporarily moved, and the opening of the small storage portion is defined as a first system in which the opening faces the front of the bookcase, and the opening is on the outer surface of the bookcase. The second system that faces and the third system that the opening faces the back of the bookshelf can be selected, and the small storage part and the large storage part are made adjacent to each other in the state of use in each system.

The first embodiment will be described in detail with reference to the accompanying drawings.
1 and 2, reference numeral 1 denotes a desk. The desk 1 includes a top plate body 10 and left and right legs 2 and 2 connected to the left and right ends of the top plate body 10 by connecting screws. Has been.
Reference numeral 20 denotes a leg reinforcing member that connects the left and right legs 2 and 2, and reference numeral 200 denotes an extension top plate that is connected to the rear end of the top plate body 10 via an attachment member. In the case of not expanding, the front surface of the leg reinforcing member 20 is fixed with screws.
5 and 6, reference numeral 3 denotes a bookcase that can be connected to the desk 1.

As shown in FIG. 3, the top plate main body 10 is moved horizontally to a rectangular top plate 11 mainly extending in the left-right direction and a pair of front and rear guide rails 12, 12 extending in the left-right direction on the bottom surface of the top plate 11. It consists of a drawer unit 13 that can be suspended.

Since the guide rails 12 of the same shape are symmetrically disposed in a pair of front and rear, only the front guide rail 12 will be described in detail.
As shown in FIGS. 2 and 4, the guide rail 12 is formed in a length between the left and right legs 2 and 2 in the front view of the figure, and extends downward from the lower surface of the top plate 11 in the side view. Formed by a base portion 12a and a receiving portion 12b extending forward from the rail base portion 12a, the rail base portion 12a has a front surface vertical, a rear surface forms an inclined surface 12c from the upper surface downward to the front side, and a lower surface is horizontal. And the square receiving part 12b is formed from the front lower part of the rail base part 12a.

As shown in FIGS. 3 and 4, the drawer unit 13 is formed on the lower surface of the top plate 11 over almost the entire width between the front end of the top plate 11 and the front surface of the leg reinforcement member 20, and is arranged at a predetermined interval. Drawer left and right side plates 131, 131, drawer left and right side plates 131, 131 on the lower surface thereof, left and right sides between the drawer left and right side plates 131, 131, and a pair of front and rear drawer side plate reinforcing bars 132, 132, and drawer left and right side plates Slide members 133, 133, 133, and 133 that are attached to a pair of front and rear sides, and drawer support members 134 and 134 (rail members and the like) that are attached to opposing surfaces of the drawer left and right side plates 131 and 131, respectively, on the upper surfaces of 131 and 131. And a drawer 135 that can be freely inserted and removed in the front-rear direction.

Since the slide member 133 is a pair of front and rear and the same shape is symmetrically arranged, only the slide member 133 on the front side will be described in detail.
The slide member 133 is formed to have a width substantially the same as the width dimension of the drawer left and right side plates 131 in a front view, and as shown in FIG. 4, a rectangular base portion 133a that rises upward from the upper surface of the drawer left and right side plates 131 in a side view. The engaging portion 133b extends rearward from the upper rear surface of the base portion 133a, and the sliding portion 133c bulges upward in an arc shape so as to connect the upper surface of the base portion 133a and the upper surface of the engaging portion 133b. That is, it is formed in an L shape that is upside down.

  The drawer unit 13 is placed on the upper surface of the receiving portion 12b of the guide rail 12 so that the lower surface of the engaging portion 133b of the slide member 133 is placed on the upper surface of the top plate main body portion 10 thus configured. The slide member 133 and the guide rail 12 are engaged with each other while being moved in the left-right direction. Alternatively, after the drawer unit 13 is disposed at a predetermined position on the top plate main body 10, the guide rail 12 that has been removed in advance is placed on the upper surface of the receiving portion 12 b of the guide rail 12 and the lower surface of the engaging portion 133 b of the slide member 133. So that the slide member 133 and the guide rail 12 are engaged with each other.

Thus, the drawer unit 13 engaged with the top plate body 10 can slide in the left-right direction within the range of the length of the guide rail 12.
In addition, the sliding part 133c of the slide member 133 makes the upper end part of a bulging form contact the lower surface of the top plate 11 in order to suppress the rattle which generate | occur | produces when the drawer | drawing-out unit 13 moves upwards. Moreover, since the sliding part 133c has made the upper end part of the bulging form contact the lower surface of the top plate 11, it becomes a substantially line contact with the top plate 11, an excessive resistance is not produced, and when the drawer | drawing unit 13 moves right and left It can solve problems such as being overly heavy and getting stuck and difficult to move from side to side.

Since the left and right legs 2 and 2 are formed symmetrically facing each other, only one side will be described.
The right leg 2 includes a prismatic front support leg 21 and a rear support leg 22 that are spaced apart from each other in the front-rear direction, and the front support leg 21 and the rear support leg 22 are arranged above the front support leg 21 and the rear support leg 22. The upper reinforcing member 221 to be connected is integrally formed and is formed in a downward U shape in a side view.
The left and right legs 2 and 2 are fixed to the lower surface of the top plate 11 with screws.

As shown in FIGS. 7 and 9, the bookcase 3 includes a large storage unit 300 and a small storage unit 400, and the top surface of the bookcase 3 is set to be the same height as the top surface of the table top 11 of the desk. The small storage unit 400 is formed to be rotatable about a vertical axis.
The large storage unit 300 has a horizontally long rectangular base body 31 having a width substantially the same as the desk top plate 11 and a depth of about half the depth of the desk top plate 11 in plan view, and a base body. A side plate 32 standing on the upper surface of the side end portion on the side opposite to the small storage portion 300 of 31, and standing on the upper surface closer to the inside than the opposing end portion of the side end portion by which the small storage portion 300 can be accommodated Between the side plates 33 and the side plates 32 and 33, the plate-like bookshelf top plate 30 is formed on the upper end surface of the side plate 33, the side plate 32, and the middle side plate 33, and is formed so as to be detachably connected. The upper and lower back plates 35, 35, which are detachably attached to the intermediate plate 36, and the large back plate 38, which is detachably provided between the side plates 32, 33.
The large storage portion 300 is formed to be a horizontally long rectangle in plan view, and is an opening 300a in which one side of the long side, that is, the opposite surface side of the back plate is opened, Is done.

  As shown in FIG. 10, in the large storage section 300 configured in this way, a base body 31 and a bookshelf top plate 30 protrude from the middle side plate 33 toward the side, and the base body 31 and the bookshelf top plate 30 and the middle plate 33 form a space 301 in which one side and front and rear surfaces are open.

The space 301 is formed in a substantially square shape in plan view, and the bookcase top plate protrusion 30a located in the space 301 and the base body protrusion 31a that is also located in the space 301 form a substantially square shape in plan view. .
And the guide groove 301a is provided in the lower surface of the bookshelf top-plate protrusion 30a located in the space 301, and the upper surface of the base body protrusion 31a.
As shown in FIG. 12, the guide groove 301a of the bookshelf top plate protrusion 30a is obliquely rearward from the reference line, with the center of the shelf top plate protrusion 30a as the base point and a line parallel to the longitudinal direction of the book shelf 3 as a reference line. And extends toward the open side of the space 301.
Similarly, the side of the open side of the space 301 obliquely forward from the reference line with the line parallel to the longitudinal direction of the bookcase 3 as the reference point, with the center of the substantially square bookcase top plate protrusion 30a in plan view as the base point Stretched toward. Therefore, the guide groove 301a is formed in a V shape by a front guide groove and a rear guide groove having the same base point.
The width and depth of the guide groove are set such that a rotation shaft 45 provided in the bookcase 3 to be described later can enter.
The guide groove 301a in the embodiment extends at an angle of 45 degrees from the reference line and extends obliquely forward and rearward toward the open side surface of the space 301, and the angle between the two guide grooves is It is set at 90 degrees. As shown in FIG. 13, the guide groove 301a on the upper surface of the base body protrusion 31a has the same configuration as the guide groove 301a of the bookcase top plate protrusion 30a.

As shown in FIG. 11, the small storage unit 400 includes a pair of small side plates 40, 40 that are erected in a symmetrical manner, and a back plate 41 that is laid between the small side plates 40, 40 at the rear end of the small side plate 40, A small bottom plate 42 horizontally installed between the small side plates 40, 40 at the lower end of the small side plate 40, and a small top plate 43 horizontally installed between the small side plates 40, 40 at the upper end of the small side plate 40, It comprises a shelf 44 that is detachably mounted at an intermediate height between the small side plates 40, 40.
The small top plate 43 has a rotating shaft 45 standing upward from the center of the small top plate 43, and a sliding plate 46 is attached around the rotating shaft 45 on the upper surface of the small top plate 43. It has been.
A rotating shaft 45 is also provided on the lower surface of the small bottom plate 42 downward from the center of the small bottom plate 42, and a sliding plate 46 is attached around the rotating shaft 45 on the lower surface of the small bottom plate 42. ing. The small storage portion 400 is formed in a substantially square shape in plan view, and is formed as an opening portion 400a in which one surface side of the four sides, that is, the opposite surface side of the back plate 41 is opened, and serves as an access port for the storage portion.

Since the bookcase 3 is formed by combining the large storage unit 300 and the small storage unit 400 formed as described above, a method of combining the large storage unit 300 and the small storage unit 400 will be described in detail.
The bookshelf top plate 30 of the large storage unit 300 is attached to the upper surface of the side plate 32 and the middle side plate 33 by a connection metal fitting 50 (described later) using a known technique (for example, a knockdown metal fitting 5 described in Japanese Patent No. 5336129). Therefore, the connection bracket 50 is unfastened and the bookshelf top 30 is removed.

Next, the rotary shaft 45 on the small bottom plate 42 side of the small storage unit 400 is inserted into the guide groove 301a on the upper surface of the base body protrusion 31a, and the small storage unit 400 is set up vertically. The rotary shaft 45 of the small top plate 43 of the small storage portion 400 is inserted into the guide groove 301a of the top plate protrusion 30a, and attached to the upper surfaces of the side plate 32 and the middle side plate 33.
Then, the small storage portion 400 is slid along the guide groove 301a with the open surface side of the small storage portion 400 facing the front, so that the side surface of the small side plate 40 and the side surface of the middle side plate 33 are aligned (FIG. 7). State).
The small side plate 40 and the middle side plate 33 are fixed with screws, and the assembly of the bookcase 3 is completed.
Note that a screwing hole is provided in advance on the outer surface side of the middle side plate 33, and a through hole corresponding to the screwing hole is provided in the small side plate 40. The screw is attached to the screwing hole of the inner side plate 33 through the through hole from the inner surface side of the small storage portion 400.

As a method of rotating the small storage unit 400, first, the aforementioned screw is removed, and the small storage unit 400 is slid obliquely forward and outward along the guide groove 301a. In this state, the rotation shaft 45 of the small storage unit 400 moves diagonally forward and outward along the guide groove 301a, and thus the center of rotation of the small storage unit 400 moves forward and outward.
Then, in this state, the small storage portion 400 is rotated 90 degrees, and the small storage portion 400 is slid along the guide groove 301a with the opening 400a facing outward, and the back plate 41 of the small side plate 40 is moved. And the side surface of the inner side plate 33 is in a state along it. The back plate 41 and the middle plate 33 are fixed with screws using the through holes of the back plate 41 provided with the through holes in advance in accordance with the screw holes on the outer surface side of the middle plate 33 described above. 400 rotation operations are completed.
When the small storage unit 400 is further rotated 90 degrees in the same operation procedure, the opening 400a of the small storage unit 400 can be directed to the back side of the bookcase 3.

Since the small storage unit 400 forms a substantially square shape in a plan view, when the small storage unit 400 rotates, a rotation locus with a diameter of a diagonal of the substantially square shape is drawn in a plan view (FIG. 14 and FIG. ).
Therefore, by moving the rotation center axis forward and outward along the guide groove 301a, the rotation trajectory during rotation of the small storage portion 400 does not interfere with the middle plate 33 of the large storage portion 300 (FIG. 14). Therefore, the small storage unit 400 can have substantially the same capacity as the space 301 of the large storage unit 300 included in the small storage unit 400, and a large storage amount can be secured.
Moreover, even if there is a wall on the back of the bookshelf 3 by moving the rotation center axis to the front outside, the rotation trajectory at the time of rotation of the small storage unit 400 does not interfere with the wall, so that the bookshelf 3 is not moved. The direction of the open side of the small storage unit 400 can be easily changed.

And since the guide groove 301a of the large accommodating part 300 is provided with the guide groove of the back side, the small accommodating part 400 can also be moved to the outer back and rotated (FIG. 15). With the guide groove on the rear side, it is possible to change the left and right arrangement of the large storage section 300 and the small storage section 400 by rotating the entire bookcase 3 by 180 degrees about the vertical axis. When the left and right arrangements of the large storage unit 300 and the small storage unit 400 are changed by rotating 180 degrees, the rear guide groove inevitably changes to the front guide groove. The storage unit 400 can be rotated.

  However, in this case, since the upper and lower back plates 35 and 35 and the intermediate back plate 36 of the large storage unit 300 are arranged from the back side to the front side, the upper and lower back plates 35 and 35 and the intermediate back plate 36 are temporarily removed from the front side. Move to the back side. Therefore, the upper and lower back plates 35, 35 and the intermediate back plate 36 are detachably connected by a connecting metal fitting 50, which is a known technique, like the bookcase top plate 30.

As described above, the guide groove 301a includes both the front side guide groove and the rear side guide groove, and the base point is the same. Therefore, the small storage portion 400 can be slidably moved both on the front side and the rear side. Since the back plate of the large storage section 400 can also be moved on the front side and the back side, the book shelf 3 can be used for both right and left, so it can be adapted to the layout of the room and is convenient. The guide groove 301a is not limited to a V shape by the front guide groove and the rear guide groove having the same base point. For example, a groove that laterally moves from the base point is provided, The guide groove on the front side and the guide groove on the rear side in a V shape may be used as the base point, so that the rotation axis of the small storage portion 400 is inclined front side and diagonal rear side. Any shape can be used as long as it is movable.

Since the sliding plate 46 made of fluororesin or the like is attached to the lower surface of the small storage unit 400, the small storage unit 400 can be stored even when the article is put in the small storage unit 400 and the weight is increased. The part 400 can be slid and rotated.
Further, since the sliding plate 46 is also attached to the upper surface of the small storage unit 400, the small storage unit 400 can be slid and moved even when a load is applied to the bookshelf top plate 30.
The sliding plate 46 is inexpensive because it is simply affixed with a material having a good sliding property such as a fluororesin.
In addition, since the length in the left-right direction of the bookshelf top plate protrusion 30a is shorter when the middle side plate 33 of the large storage portion 300 is installed in the vicinity of the small storage portion, the bookcase top plate protrusion 30a is less likely to bend. Therefore, it is convenient because the small storage unit 400 can be easily moved and rotated.

The connecting metal fitting 50 will be described in detail with reference to FIG.
The connection fitting 50 is composed of a connection pin 502 and a columnar fastening fitting 501. One end of the connection pin 502 is a male screw portion 503, and the other end has a small diameter shaft portion 504 and a small diameter shaft portion 504. A large-diameter head 505 is integrally formed at the tip. The fastener 501 has an engagement groove hole 506 with which the large-diameter head portion 505 engages and an arcuate guide groove 507 with a small groove width into which the small-diameter shaft portion 504 is slidably fitted. In this way, a rotation groove 508 is formed on the flat surface portion for rotating the fastener 501 with a screwdriver or the like.
As described above, such a connecting metal fitting is a known technique.

For example, in order to connect the bookshelf top plate 30 and the inner side plate 33, the male screw portion 503 of the connection pin 502 is screwed into the screw hole 60 provided on the lower surface of the bookcase top plate 30.
Then, the large-diameter head portion 505 side of the connecting pin 502 is inserted into the connecting hole 331 on the upper surface of the middle plate 33. At this time, the small diameter shaft portion 504 and the large diameter head portion 505 of the connection pin 502 are fitted into the guide groove 507 and the engagement groove hole 506 of the connection fitting 50.
