Description

  The present invention relates to a double top plate desk having first and second top plates.

  Conventionally, a personal computer (personal computer) and a display, keyboard, and other peripheral devices are mounted together, and a sub-top for placing the keyboard is provided below the main top as a personal computer desk for work. A structure is known in which a sub-top plate is pulled out and used when necessary, and when not in use, the sub-top plate is pushed in to house the keyboard under the main top plate.

  Patent Document 1 proposes a personal computer desk which is a desk for operating a personal computer and configured to be capable of office processing at the same time. This personal computer desk has a problem that a chair is not retracted when performing personal computer operation or paperwork, and as a result, a large office is not required. Therefore, it has a lower top plate where the keyboard is placed at a position lower than the general desk top plate, and an upper top plate for paperwork is slidably mounted above the lower top plate, and the upper top plate is displayed behind the display when operating the keyboard. It is configured to be positioned in the space under the table and to be used by pulling the upper top plate forward on the keyboard during paperwork.

  Patent Document 2 proposes a desk with a slide top plate that can draw out a slide top plate for customer service on the side facing the owner sitting on the desk. This desk with a slide top can be used as a normal office desk when the slide top is pushed into the lower side of the desk top and retracted, and the slide top is pulled out to the owner's seating side and facing side when serving customers. It can be used.

JP 2001-218635 A Japanese Utility Model Publication No. 5-34925

  In the personal computer desk of the above-mentioned patent document 1, the upper top plate has a limited area that is smaller in depth and width than the lower top plate. Not. In addition, since this top plate enters under the display stand when not in use, it can be used for the purpose of placing documents, but since it enters under the display stand, the document can be viewed as it is. It is difficult to do, and it is also difficult to use as an active work space. Furthermore, even when nothing is placed on the upper top plate, anything placed on the lower top plate located below it is hidden by the upper top plate.

  Therefore, in the prior art described in Patent Document 1, there is a problem that both top plates are not always effectively used while having two top plates, an upper top plate and a lower top plate.

  In the desk with the slide top plate of Patent Document 2, the slide top plate has substantially the same width as the desk top plate, and the depth dimension has a size close to that of the desk top plate. It is possible to greatly expand the top board area of the entire desk. However, this slide top plate is used by pulling the slide top plate toward the seating side and the facing side of the owner when serving customers, and does not expand the work space for the owner. Although it is not impossible for the owner to use the pulled slide top as an expansion work space, the slide top is stored under the desk top so that it always goes behind the desk each time it is pulled out. Therefore, it is not realistic to use it for expanding the work space for the owner. In addition, there is only a space between the slide top plate and the desk top plate to avoid contact between the two, and the slide top plate stored under the desk top plate has a special function (use). Not.

  Therefore, even in the prior art described in Patent Document 2, there is a problem that the two top plates, the table top plate and the slide top plate, cannot always be effectively used.

  The present invention has been made in such a background, and an object of the present invention is to provide a double ceiling capable of securing a sufficient area for placing and storing objects and expanding the work area as necessary. To provide a board desk.

  The double top plate desk according to the present invention has a first top plate, a leg portion for supporting the first top plate, and substantially the same size and shape as the first top plate, A second top plate disposed on the top plate so as to be slidable substantially parallel to the first top plate and rearward of the desk; and at least a part of the second top plate is transparent. It is composed of possible members.

  The first and second top plates can be placed on top of each other, and the items placed on the lower first top plate are seen through from the upper second top plate. be able to.

  The user can enlarge the work area by exposing at least a part of the first top plate by simply sliding the upper second top plate backward without retreating as necessary. it can.

  The first top plate and the second top plate preferably have a predetermined interval so as to form a space between the top plates in a state where the top plates overlap each other. Thereby, the space between the first top plate and the second top plate also functions as a storage space for objects.

  A slide mechanism disposed between an upper surface of the first top plate and a lower surface of the second top plate, and slidably supporting the second top plate on the first top plate; Good. By disposing the slide mechanism between the upper surface of the first top plate and the lower surface of the second top plate, the relatively heavy first top plate can be reliably supported by the slide mechanism.

  The leg portion may include a caster portion that movably supports the leg portion. Thereby, when there is no space for sliding the second top plate backward, it is possible to easily move the leg portion to the front side of the desk temporarily.

  In this specification, the term “desk” means a desk, but is used in a broad sense including a table.

  According to the double top board desk of the present invention, a sufficient area for placing and storing objects can be secured, and the work area can be expanded as necessary. In other words, various functions such as placing an object on the desk, viewing an object on the desk, storing an object in the desk, and working on the desk are simultaneously realized and work as necessary. By expanding the area, the two top plates can be used effectively individually and in cooperation.

It is sectional drawing which showed the specific example of the mutual connection means of each part of the double top board desk by embodiment of this invention.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a perspective view showing an appearance of a double top board desk according to the present embodiment.

  This double top panel desk includes a first top panel 10, leg portions 40 that support the first top panel 10, and a second top panel 20. The second top plate 20 has substantially the same size and the same shape as the first top plate 10 and is disposed on the first top plate 10 in parallel with the first top plate 10.

  FIG. 2 is a perspective view showing a state in which the second top board 20 of the double top board desk shown in FIG. 1 is slid. As shown in FIG. 1, the double top board desk has a structure in which the top boards are superposed on each other, as shown in FIG. 2, with respect to the first top board 10 that is the lower top board. The second top plate 20 that is the upper top plate can be slid rearward of the desk (in the direction indicated by the arrow R in FIG. 1). “Back of desk” usually means the direction opposite to the side of the user sitting on the desk.

  In order to allow the second top plate 20 to slide with respect to the first top plate 10, the first top plate is provided between the surface of the first top plate 10 and the lower surface of the second top plate 20. A slide mechanism 30 that supports the second top plate 20 so as to be slidable rearward of the desk on the top 10 is disposed.

  In the present embodiment, the second top plate 20 is configured with a transparent (transparent) member. Tempered glass can be used as an example of the material. However, the entire second top plate 20 does not necessarily need to be seen through, and may be configured such that only a part thereof can be seen through.

  The leg portion 40 includes a plurality of (two in this example) support columns 41 that support the first top plate 10 and two leg plates 43 that extend in the front-rear direction. The two leg plates 43 support the lower portions of the respective columns 41 at the center thereof. Although not essential to the present invention, the leg plate 43 is provided with a caster portion 45 that supports the leg portion 40 movably at the front end and the rear end thereof.

  FIG. 3 is a front view of the double top board desk. FIG. 4 and FIG. 5 are right side views of the double top board desk at the time of reduction and extension, respectively.

  As can be seen from these drawings, the two support columns 41 of the leg portion 40 are each provided with two support beams that extend horizontally in the front-rear direction and support in the vicinity of the left and right ends (both sides) of the first top plate 10. 42 substantially supports the central portion. A support beam portion 44 that extends horizontally and supports the top plate 10 is provided between the central portions of the two support girders 42.

  The first top plate 10 and the second top plate 20 have a predetermined distance d so as to form a storage space S (see FIG. 3) between the top plates in a state where the top plates overlap each other. The predetermined distance d is not particularly limited and may vary depending on the application and function. For example, the predetermined distance d is about several mm to 10 cm, and in the present embodiment, 5 to 6 cm is assumed.

  The use of the storage space S between the top plates is not particularly limited, but it is not simply used for storage purposes. For example, stored items such as calendars, photographs, and reference materials are placed on the first top plate 10. It is suitable for a use in which the stored item is seen through from above the second top plate 20. Placement of stored items on the first top plate 10 is more difficult to place objects or users on the second top plate 20 when working at the desk than when placing the items on the second top plate 20. Hands do not interfere, and the stored items do not hinder work. The addition, removal, and replacement of the stored items do not require the user to retreat (for example, retreat the seated chair), and the second top plate 20 is slid rearward of the desk so that the first top plate 10 is in front of the user. It can be done quickly and easily by exposing from the side.

  By providing the casters 45 in the legs 40, the legs 40 are temporarily moved to the front side of the desk when there is no space behind the desk for sliding the second top plate. Can be done easily.

  In addition, when the work area is not enough only by the second top plate 20, the second top plate 20 is slid to the rear of the desk, and the exposed area of the first top plate 10 is used as an additional work area. It becomes possible to do.

  FIGS. 6A and 6B are side views of an example of the slide mechanism 30 at the time of reduction and extension. 7A and 7B are perspective views of an example of the slide mechanism 30 at the time of reduction and expansion.

  As clearly shown in FIG. 6A, the slide mechanism 30 includes a slide rail unit SRU, a spacer member 37, and a support plate portion 38.

  The slide rail unit SRU includes an outer member 31, an intermediate member 33, and an inner member 35 that are three long elongated members. The outer member 31 is a long member fixed to the surface of the first top plate 10. The means for fixing is not particularly limited, but known means such as screwing can be used. The intermediate member 33 is slidably supported along the longitudinal direction of the outer member 31. Further, the inner member 35 is slidably supported along the longitudinal direction of the intermediate member 33. Although not particularly illustrated, lubricating means such as a ball bearing may be provided between the long members that slide with each other.

  Although the detailed structure is not shown, a stopper is provided at a predetermined position when the intermediate member 33 is retracted and extended with respect to the outer member 31, and the movable range of the intermediate member 33 with respect to the outer member 31 is limited. Similarly, stoppers are provided at predetermined positions when the inner member 35 is retracted and extended with respect to the intermediate member 33, and the movable range of the inner member 35 with respect to the intermediate member 33 is limited.

  With such a so-called three-stage pulling slide mechanism, the sliding amount of the inner member 35 relative to the outer member 31 can be increased compared to the two-step pulling mechanism while maintaining load resistance. However, the present invention is not limited to the three-stage drawing configuration. As such a three-stage slide rail unit SRU, for example, an aluminum alloy slide rail CBL-D500 manufactured by Sugatsune Industry Co., Ltd. can be used.

  A spacer member 37 is fixed to the upper surface of the inner member 35. The fixing means is not particularly limited. The spacer member 37 includes an upright portion 37 a that stands upward from the inner member 35 and a support plate portion 38 that extends horizontally from the upper side thereof. The height of the storage space S between the top plate 10 and the top plate 20 is determined by the height of the spacer member 37. The upright portion 37a is provided with an opening 37c along the longitudinal direction thereof. The opening 37c is for reducing the weight and material of the slide mechanism and is not an essential element of the present invention.

  As clearly shown in FIG. 4, the top plate 20 is fixed to the support plate portion 38 so that the support plate portion 38 supports the top plate 20. This fixing is performed by fixing the top plate 20 to the support plate portion 38 using a fixing tool 39. A specific example of the fixture 39 will be described later.

  The support plate 37b does not directly support the top plate 20, but supports the top plate 20 via a support plate portion 38 having a wider width and a longer length. Thereby, attachment to the spacer member 37 of the top plate 20 made of tempered glass is made reliable and easy.

  A specific example of the means for connecting the top plate 20, the support plate portion 38, the spacer member 37, and the SRU will be described with reference to FIG.

  As described above, the top plate 20 is fixed to the support plate portion 38 using the fixture 39. In this specific example, the fixture 39 is inserted into a frame-shaped nut 39a fitted in a predetermined position on the top plate 20 by inserting a bolt 38a from the lower side of the support plate portion 38, and is fastened and fixed to the nut 39a. Is. The head of the nut 39 a has a dish shape, and the upper surface thereof is installed so as to coincide with the surface position of the top plate 20. Therefore, the surface of the installation position of the nut 39a of the top plate 20 is cut into a mortar shape.

  The connection between the support plate portion 38 and the spacer member 37 is realized by screwing the spacer plate 37 from the support plate 37b side to the support plate portion 38 with a bolt 37d at a predetermined position.

  The spacer member 37 and the SRU are connected to each other by screwing the SRU inner member 35 with a bolt 37e from the spacer member 37 side at a predetermined position.

According to the double top desk of the present embodiment described above, the following functions and operational effects can be obtained.
(1) An object can be placed on each top plate of the double top plate. That is, compared with a conventional desk having only a single top plate, the area for placing objects increases.
(2) By configuring the second top plate with a see-through member, it is possible not only to see what is placed on the second top plate, but also on the first top plate through the second top plate. You can see things. Such “thing on the first top plate” is not limited as long as it is of a size that can be stored. For example, a closed or open book, magazine, printed matter, keyboard, mouse, etc. Peripheral devices, electronic devices such as tablets and smartphones having a display screen, etc. can be visually recognized and the operating state (power light, display screen, etc.) can be confirmed through the second top board. That is, the desk space that can be used visually is expanded.
(3) Placing an object on the lower side (first top plate) also stores the object in the storage space. The stored item can be seen through from the second top plate. For the time being, objects that do not need to be seen or that need not be picked up by hand can be placed on the first top plate.
(4) The upper surface of the second top plate not only serves as a work area, but also by sliding the second top plate to the back of the desk, the upper surface (at least part of) the first top plate is used as the work area. Can be used. That is, the total work space can be increased. For example, a computer display device is placed on the upper top plate (second top plate), and peripheral devices such as a keyboard, mouse, and touch pad are placed on the lower top plate (first top plate). can do. Accordingly, the peripheral device can be stored under the second top plate when not in use, and the second top plate can be slid to the desk gazette when necessary to expose the peripheral device operably. . During storage, the second top plate functions as a cover for the peripheral device, so that the possibility of accumulation of dust on the peripheral device is reduced or it is prevented from being contaminated with a drink such as a bag. be able to.
Further, at that time, it is not necessary for the user to retreat (for example, to retreat a seated chair). As a result, even when there are obstacles such as walls, shelves, cabinets, and sills immediately behind the user, the sliding operation of the top board does not occur.
(5) When the display device is placed on the second top plate, the screen can be viewed from the user's (viewpoint) without changing the user's (chair) position by sliding the second top plate back and forth. The distance to can be adjusted.

  According to the double top board desk of the present embodiment, such various functions can be realized simultaneously and the two top boards 10 and 20 can be effectively utilized comprehensively.

  The preferred embodiments of the present invention have been described above, but various modifications and changes other than those mentioned above can be made.

  For example, a third top plate may be provided in addition to the first and second top plates. In that case, it is desirable that the upper two top plates be made of a transparent member. You may vary the space | interval of a 1st and 2nd top plate, and the space | interval of a 2nd and 3rd top plate.

  Although the number of the support | pillars of the leg part 40 was two, it does not restrict to this. For example, there may be four. The configuration and the number of the support girders 42 and the support beam portions 44 are not limited to those illustrated.

  The caster part 45 of the leg part 40 is not necessarily required.

  In some cases, when the upper top plate (second top plate) is slid to the rear side of the desk, the stability of the posture of the entire desk may be lowered. In particular, when a heavy object is placed at the rear position of the second top plate, a force (moment) is applied to cause the desk to fall backward. In order to cancel or reduce such force, the material, shape, size, etc. of the whole or a part of a specific member (for example, the leg portion 40) can be changed, or an additional member (for example, a heavy object) Or a support member) may be installed.
