Description

  The present invention relates to a top plate applied to a table.

In the top plate of a table (including a desk, the same applies hereinafter), an upper top plate and a lower top plate are vertically superposed so that they can be moved relatively (for example, Patent Document 1). The top plate described in the document is a double top plate having an upper top plate (upper plate) and a lower top plate (lower plate), and the upper top plate is horizontally rotated or horizontally slid with respect to the lower top plate. Thus, not only the upper surface of the upper top plate but also the upper surface of the lower top plate are exposed upward, and the top surface for placing the article is expanded.
Japanese Patent Laid-Open No. 9-224746

  A large table for meetings, etc. installed in an office has a space for storing small items such as writing instruments and instruction pointers often used in work using the table, or a power outlet or an information outlet. Therefore, there is a problem that you have to prepare a separate accessory storage device or extend the cable from the outlet provided on the floor or wall to the top plate. There is a user's request to attach it to the table. However, in the conventional double top plate as described above, the upper surface of the exposed lower top plate has the same function as a normal top plate surface, that is, the function of placing articles, like the upper surface of the upper top plate. And did not satisfy the user's wishes. In this case, providing an appropriate drawer or the like on the lower surface side of the top plate is also considered as a solution to the above-mentioned problems. However, since the lower space of the top plate is narrowed for the extraction, a particularly large number of people are required. It is not appropriate to provide a drawer on a meeting table where the legs are placed in the space below the top board. In particular, in a structure where the upper top plate is rotated horizontally, it is difficult to perform the desired function by sufficiently rotating the upper top plate in an office or the like where only a narrow and limited space can be secured. If the upper top plate is pulled out to expose the lower top plate for the purpose of expanding the surface, the upper top plate can be stabilized without using the auxiliary legs provided on the lower surface side of the upper top plate. The problem of not being able to occur can arise.

  Therefore, in view of the above problems, the present invention provides a top plate having a double top plate structure, which has a compact structure and can realize not only the expansion of the top plate surface but also the storage function of articles. It is something to be offered.

  That is, the top plate of the present invention mainly conceals the lower top plate from above by an upper top plate having an upper surface that is mainly a mounting surface of the article, a lower top plate disposed on the lower surface side of the upper top plate, and the upper top plate. A moving mechanism for relatively moving the upper and lower top plates between a normal use position and an open use position in which a part of the upper surface of the lower top plate is opened upward without being covered by the upper top plate. In the open usage position, the exposed portion of the lower top plate is provided with a storage portion that can store articles used for work on or around the top plate. Yes. Here, “articles used for work on or around the top board” means, for example, accessories such as pens, stationery, instruction pointers, power supplies, and information. The term “accommodating portion” that means an outlet or the like and can store such articles corresponds to a tray for storing small items, an outlet holder, and the like in the above example. Furthermore, what has a function which accommodates articles | goods, such as an ashtray as an aspect of a tray, is contained in the concept of a "storage part".

  In the case of the top plate having such a configuration, in addition to performing the original function of placing the article in the normal use position, the upper top plate and the lower top plate are simply moved relative to the open use position. In order to expose the storage unit as described above in an upwardly opened state, not only the article is placed, but also the article used on or around the top plate is effectively hidden in the normal use position. In the open use position, the top plate can be provided with an excellent function of using these articles with ease. Therefore, when the present invention is applied to a large meeting table that is not suitable for attaching a drawer, a functional and excellent top plate can be applied. In addition, the relative moving direction of the upper top plate and the lower top plate by the moving mechanism is not particularly limited.

  In such a top plate, in order to make the use of the upper surface of the upper top plate, which is the mounting surface of the main article, equivalent to the case of the normal use position even in the open use position, the moving mechanism is provided with the height of the upper surface of the upper top plate. It is desirable that the upper top plate and the lower top plate are slid relative to each other while maintaining the position.

  Furthermore, in order to enable relative movement of the upper and lower top plates even in a narrow space and to make the operability simple, the moving mechanism is designed to move the upper and lower top plates in one direction. It is preferable that the relative slide movement is performed reversibly.

  In this case, the guide groove is formed as a long groove formed along the longitudinal direction of the lower top plate or the upper top plate, and the slider can be attached to the upper top plate or the lower top plate along the long groove-shaped guide groove. By using a member having a longitudinal dimension in a direction coinciding with the longitudinal direction of the upper top plate or the lower top plate, the relative sliding movement between the upper top plate and the lower top plate is smooth and free from blurring. When the plate or the lower top plate is a wooden top plate, the warp on which the slider is attached can be suitably prevented while effectively using the constituent members of the moving mechanism.

  Furthermore, the lower top plate or the upper top plate in which the guide groove is formed is provided with a restricting member having a slit communicating with the guide groove and extending in the same direction as the guide groove. The restricting member and the slider can be slidably moved up and down. If the upper and lower separation restricting portions that restrict the vertical separation between the upper and lower top plates are formed by impossible engagement, stabilization of relative sliding movement between the upper and lower top plates and the vertical direction It is possible to prevent warping of the lower top plate or the upper top plate on the side where the restricting member is provided, while preventing separation of the upper top plate.

  In addition, not only in such a configuration, in order to prevent the top and bottom from being separated from each other while realizing only the necessary relative movement between the top and bottom top plates, the top and bottom top plates can be separated from each other. It is preferable to provide an appropriate vertical separation restricting portion for restricting the vertical separation from the vertical direction.

  In addition, in order to prevent downsizing so that the thickness of the entire top plate does not become excessive due to the presence of the moving mechanism, the moving mechanism is formed by opening upward on the upper surface of the lower top plate or the lower surface of the upper top plate. It is effective to form a guide groove formed by opening downward to the bottom and a slider provided on the lower surface of the upper top plate or the upper surface of the lower top plate so as to move in the guide groove.

  Furthermore, even if the storage section is provided on the lower top plate, the thickness of the entire top panel does not change, and in order to maintain a compact structure, the upper end of the storage section is approximately the same height as the upper surface of the lower top plate. It is preferable to set the position.

  As described above, examples of the appropriate storage unit include a tray that can store small items such as a pen, and an outlet holder that can store a power source or an information outlet.

  The top plate according to the present invention has a double top plate structure of an upper top plate and a lower top plate, and further includes a moving mechanism that relatively moves them, and the upper and lower top plates are moved by this moving mechanism. Are moved relative to each other between a normal use position where they are superposed vertically and an open use position where the lower top plate is partially opened upward and the storage portion provided on the lower top plate is exposed. It can be configured as follows. Therefore, in the normal use position, the upper surface of the upper top plate exhibits the original function of placing the article, and in the open use position, in addition to the article placement function by the upper surface of the upper top plate, It exhibits the function of suitably storing small items such as pens and instruction pointers, or outlet holders. That is, such a top plate not only mounts the article, but also hides the article in the storage unit in the normal use position, and moves the upper and lower top boards relatively only when necessary. An article can be taken out, and a functional and useful top plate can be provided when applied to a meeting table where it is difficult to provide a drawer.

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

  The top board 1 of this embodiment shown in FIGS. 1 and 2 is applied as a top board of a meeting table (hereinafter abbreviated as “table”) T suitable for a conference or work with a large number of people. Here, although the top plate 1 is supported by a pair of leg bodies TL having a leg column TL1 and a plurality of leg blades TL2 at one end portion thereof, the table T is shown. The support structure is not particularly limited, and one or both of the leg structures may be a sleeve structure or a leg plate, or may be used as a leg of a general table. Hereinafter, the structure of the top plate 1 will be specifically described.

  The top plate 1 has a double top plate structure in which an upper top plate 2 and a lower top plate 3 are vertically stacked, and a moving mechanism 4 that moves the upper top plate 2 and the lower top plate 3 relative to each other. I have. In the present embodiment, the moving mechanism 4 allows the upper top plate 2 to slide in the horizontal direction with respect to the lower top plate 3 supported by the pair of legs TL. Specifically, the sliding movement of the upper top plate 2 includes the normal use position P that is substantially completely overlapped with the lower top plate 3 as shown in FIG. 1 and the upper surface of the lower top plate 3 that is shifted in the horizontal direction as shown in FIG. Is carried out in both directions with the open use position Q, which is partially exposed upward. And in the open use position Q, as shown in FIG. 2, the accommodating part 31 formed in the lower top plate 3 is opened upwards in the exposed part of the lower top plate 3. In this embodiment, trays 31A1 and 31A2 that can store small items such as pens, and outlet holders 31B that can store power outlets 31B1 and information outlets 31B2 are applied as the storage unit 31.

  As shown in FIGS. 1, 2, and 3, the upper top plate 2 and the lower top plate 3 have substantially the same planar view shape, and the lower top plate 3 is the upper top plate at the normal use position P described above. 2 is almost completely covered from above. In the present embodiment, as the upper and lower top plates 2 and 3, wooden top plates having appropriate thicknesses that are substantially elliptical in plan view are used. A pair of legs TL are attached via a top plate receiving member (not shown). In addition, a tray 31A1 (in the example shown in the figure) and a tray 31A2 (same as a round shape) are formed at the side end of the lower top plate 3 on the side of one leg TL. In addition, an outlet holder 31B made up of a square hole penetrating vertically is formed. By doing so, the structure of the top plate 1 is configured such that the upper end of the storage portion 31 is substantially coincident with the upper surface of the lower top plate 3 and the storage portion 31 does not enter the gap between the lower top plate 3 and the upper top plate 2. We are trying to make it more compact. In addition to such trays 31A1 and 31A2, it is also possible to make a tray by fitting a dish-like member into a hole or a recess as described above that penetrates the corresponding part of the lower top plate 3 vertically, The shape of the tray itself is not particularly limited. Further, in the illustrated example, the power outlet 31B1 and the information outlet 31B2 are individually attached to the outlet holder 31B, but a general outlet such as a power outlet / information outlet is attached. You may make it.

  The moving mechanism 4 is a mechanism for horizontally sliding the upper top plate 2 with respect to the lower top plate 3 as shown in FIGS. 3, 4, and 5. Specifically, the moving mechanism 4 mainly includes a guide groove 32 formed in the lower top plate 3 and a slider 21 attached to the upper top plate 2. The guide groove 32 is a long groove-like hole that is vertically penetrated so as to extend along the long axis direction of the ellipse that is a planar view shape of the lower top plate 3, that is, the longitudinal direction of the lower top plate 3. In the present embodiment, such a guide groove 32 is formed in parallel at two locations by being biased from the central portion of the lower top plate 3 toward the one end portion. The two guide grooves 32 are formed at the front end portion and the rear end portion when the minor axis direction of the lower top plate 3 is the front-rear direction. On the other hand, the slider 21 is two long members attached to the lower surface of the upper top plate 2 corresponding to the above-described guide groove 32, and the longitudinal dimension thereof is set to about 2/3 of the longitudinal dimension of the guide groove 32. Yes. Specifically, the slider 21 has a configuration in which two L-shaped brackets 211 and 211 and a spacer 212 provided between the L-shaped brackets 211 and 211 are connected by a bolt 213. Each L-shaped bracket 211 has a horizontal piece 211 a screwed to the lower surface of the upper top plate 2 and a hanging piece 211 b inserted into the guide groove 32 from above. The spacer 212 is a block-like member that is intermittently disposed in the longitudinal direction of the L-shaped metal fittings 211 and 211 (three at regular intervals in the illustrated example), and the L-shaped metal fitting is inserted into the screw hole 212a penetrating in the horizontal direction. A bolt 213 that passes through the hanging piece 211b of 211 is tightened. Based on such a configuration, the moving mechanism 4 in this embodiment is configured to slide the upper top plate 2 relative to the lower top plate 3 as the slider 21 slides in the guide groove 32.

  Here, in the configuration as it is, there is a possibility that the upper top plate 2 may be separated upward from the lower top plate 3. Therefore, the top and bottom separation regulating portion 5 using the configuration of the moving mechanism 4 described above is used for the top plate 1 to prevent this. Is provided. As shown in FIGS. 3, 4, and 6, the vertical separation regulating portion 5 includes a regulating member 33 attached along the guide groove 32 on the lower top plate 3 and a stopper 22 fixed to the slider 21. The First, the restricting member 33 is a long channel-shaped metal fitting having substantially the same longitudinal dimension as that of the guide groove 32, and is screwed to the lower surface of the lower top plate 3 so as to straddle the guide groove 32. Further, a groove portion 331 that is recessed so as to extend in the longitudinal direction is formed in the center portion in the front-rear direction of the regulating member 33, and the upper top plate 2 between the normal use position P and the open use position Q is formed in this groove portion 331. A slit 332 substantially equal to the moving distance is formed so as to penetrate vertically. On the other hand, the stopper 22 is fastened to a stopper main body 221 fixed by welding or the like between a pair of L-shaped metal fittings 211 and 211 constituting the slider 21, and a screw hole 221a formed so as to open on the lower surface of the stopper main body 221. The bolt 222 is configured. The head of the bolt 222 is provided with a flange 222a that is wider than the opening width of the slit 332 of the restricting member 33. The bolt 222 is inserted into the slit 332 from below the restricting member 33, and the stopper main body 221 is inserted. The screw hole 221 is screwed. In this embodiment, a total of two stoppers 22 are provided between the spacers 212 adjacent to the slider 21. By doing in this way, the collar part 222a will contact | abut from the downward direction to the control member 33, and the upper space | interval from the lower top plate 3 of the upper top plate 2 will be controlled.

  As described above, the top plate 1 of the present embodiment applied to the table T has a double top plate structure in which the upper top plate 2 and the lower top plate 3 are vertically superposed, and these upper top plates are moved by the moving mechanism 4. 2 and the lower top plate 3 can be moved relative to each other, more specifically, the upper top plate 2 can be moved relative to the lower top plate 3. And in the normal use position P where the lower top plate 3 is covered from above by the upper top plate 2, it can serve as the top plate of a normal table T with the upper surface of the upper top plate 2 as a mounting surface. In the open use position Q where the upper top plate 2 is moved and a part of the upper surface of the lower top plate 3 is exposed, the trays 31A1 and 31A2 which are one mode of the storage portion 31 provided in the exposed portion of the lower top plate 3 are placed. Functions such as inserting and removing small items such as stationery such as pens and instruction pointers, and inserting plugs into the power outlet 31B1 and the information outlet 31B2 mounted on the outlet holder 31B which is also one aspect of the storage unit 31. It can be demonstrated. The small items stored in the trays 31A1 and 31A2, the power outlet 31B1 and the information outlet 31B2 attached to the outlet holder 31B can be hidden by the upper top plate 2 in the normal use position P, and are in the open use position. Also in Q, not only the upper surface of the upper top plate 2 is used as a mounting surface, but the mounting surface can be extended to a portion other than the storage portion 31 among the exposed portions on the upper surface of the lower top plate 3. That is, with the top plate 1 having such a configuration, a function of storing articles used in work around the top board 1 can be added to the function of a normal top board for placing articles. it can. This is very convenient particularly when the table T is used as a meeting table that does not normally have a storage function.

  Furthermore, since the upper end of the storage part 31 is set at a substantially same height position as the upper surface of the lower top plate 3, the storage part 31 falls within the thickness range of the lower top plate 3. The storage function can be secured in a compact manner without changing the overall thickness.

  In particular, the movement of the upper top plate 2 based on the moving mechanism 4 with respect to the lower top plate 3 is a two-way horizontal slide movement that does not involve a change in the height of the upper top plate 2. The normal use position P and the open use position P can be good, and the normal use position P and the open use position Q can be easily changed even in a narrow indoor space.

  Further, the moving mechanism 4 is composed of a guide groove 32 having a long groove shape formed in the lower top plate 3 and a slider 21 attached to the upper top plate 2 so as to move in the guide groove 32. The sliding operation of the upper top plate 2 can be realized without increasing the thickness of the entire plate 1 so much. In particular, since the slider 21 is an elongated metal member attached along the longitudinal direction of the upper top plate 2, the sliding operation of the upper top plate 2 is less likely to be shaken, and the warp of the wooden upper top plate 2 is also effectively prevented. can do.

  Further, the lower top plate 3 is provided with a regulating member 33 extending along the guide groove. The stopper 22 attached to the upper top plate 2 is inserted into the slit 332 of the regulating member 33 so as to be slidable and not vertically movable. As a result, the upper and lower separation regulating portion 5 that regulates the upward separation of the upper ceiling plate 2 from the lower ceiling plate 3 is formed, so that the slide movement is stabilized and pulled out from the lower ceiling plate 3 of the upper ceiling plate 2. Can be prevented. Furthermore, since the restricting member 33 is a metal member extending in the longitudinal direction of the lower top plate 3, it is possible to prevent warpage of the lower top plate 3 by the restricting member 33.

  The present invention is not limited to the embodiment described above. For example, the top plate 1 according to the above embodiment is a meeting table (hereinafter referred to as “table”) in which one of a pair of legs TL that support the top plate TL is a housing-like sleeve structure TS as shown in FIG. It can also be applied to T ′. In the same figure, since parts other than the sleeve structure TS are the same as those in the above-described embodiment, a description will be given with common reference numerals. In such a table T ′, a projector, a data box, a tool box, etc. are stored in the storage space TSs in the sleeve structure TS, for example, as articles used during a meeting, and these articles are stored from the storage space TSs as necessary. It is used by being placed on the upper surface of the take-out top plate 1. In addition, since it is normal for the persons participating in the meeting to gather on the side where the space below the top plate 1 is wide, that is, on the leg TL side, on the sleeve structure TS side where the space below the top plate 1 is narrow. Articles such as the projector are placed on the upper surface of the top plate 1 (that is, the upper surface of the upper top plate 2). At that time, the upper top plate 2 and the lower top plate 3 are relatively slid to the open use position Q, whereby the storage portion 31 (tray 31A1, 31A2, power outlet 31B1, information outlet) provided on the upper surface of the lower top plate 3 is provided. When the electrical outlet 31B2) is exposed, as shown by an imaginary line in the figure, the power supply of an electric device such as the projector X becomes very convenient. In addition to storing the articles, it is possible to efficiently arrange the staff around the table T ′. Furthermore, not only is the caster provided at the lower end of the sleeve structure TS, but the lower structure 3 is pivotally attached to the upper end of the sleeve structure TS. If the sleeve structure TS and the lower top plate 3 can be rotated relative to each other, the articles can be easily put in and out of the storage space TSs of the sleeve structure TS. .

  In the above embodiment and the modification, the upper mechanism plate is configured to slide in a straight line, but the upper table can be configured to slide with a rotation operation. The operation is not limited to the sliding operation, and a moving mechanism that moves the lower top plate with respect to the fixed upper top plate can be employed. Further, the vertical separation restricting portion may have an independent structure that does not use the components of the moving mechanism. Furthermore, the shapes of the upper and lower top plates can be arbitrarily changed. For example, the lower top plate may be smaller than the upper top plate. In addition, the specific configuration of each part is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
