  On the other hand, recently, the so-called free address type office form has been increasingly used, but in such an office, a large free address table that allows multiple people to work side by side on the same side of the top board. Has been applied. When such a table and the above furniture with an auxiliary top plate are used in combination, it is common to arrange the furniture with an auxiliary top plate between adjacent office workers, but the drawer can be taken in and out forward. For this reason, the drawer had to be taken in and out at the rear side of the office worker, which was inconvenient. As a result, it is necessary to provide one furniture with an auxiliary top for each office worker, and the office space is reduced, which is not practical.

  In addition, since the furniture with the auxiliary top plate is integrally attached to the main body and the auxiliary top plate via a link mechanism, for example, the shape and color of the free address table to be used together, or the preference of the office worker, etc. However, there was a problem that the auxiliary top plate could not be exchanged corresponding to the various conditions of the above, and it was very difficult to take other variations in a flexible manner.

  In addition, for example, the main body is configured to have a storage space that can be used only from one side and used as a dedicated desk for a single office worker. A furniture with an auxiliary top plate is also considered in which the side end is set as a use edge and the auxiliary top plate can be selectively attached to the front half or the rear half of the main body. If it is like this, the office worker can use the storage space from the side, but the furniture with the auxiliary top panel that was originally placed on the right side of the office worker is moved to the left side of the office worker after the layout change etc. In the case of the arrangement, it is necessary to set the auxiliary top panel appropriately so that the use edge of the auxiliary top plate faces the worker side, and there is a problem that the work cannot be easily performed. Specifically, by temporarily removing the auxiliary top plate attached to the front half of the main body from the front half of the main body, attaching it again to the rear half of the main body, and further inverting the entire furniture with the auxiliary top back The working space must be directed to the office side so that the storage space can be used from the office side. In this way, in addition to the work of attaching and detaching the auxiliary top plate, it is necessary to reverse the entire furniture with the auxiliary top plate, which causes a problem that the work is very troublesome. In particular, when the support pins are arranged at the four corners on the lower surface of the auxiliary top plate, the attaching / detaching operation of the auxiliary top plate becomes extremely troublesome. Furthermore, even in such furniture with an auxiliary top plate, when used together with a free address table, there still remains a problem that the left and right office workers cannot share.

  The present invention has been made paying attention to such problems. The main purpose of the present invention is to use it in combination with a free address table so that it can be shared by adjacent office workers. The object is to provide furniture with an auxiliary top that can be changed according to the preference of the office worker.

That is, the furniture with an auxiliary top plate of the present invention can be used together with furniture with a top plate such as a table or a desk, and a main body part that can be partially accommodated in a space below the top plate of the furniture with a top plate. And an auxiliary top plate disposed above the front half or the rear half of the main body and configured to be set at substantially the same height as the top. A height adjusting mechanism that can be used from both the left and right sides, the auxiliary top plate is detachably attached to the main body, and the height position of the auxiliary top plate can be adjusted. An operation unit that is provided at two locations on the main unit , and that the height adjusting mechanism integrally includes an operation unit main body that can rotate horizontally and a screw shaft that rotates about the vertical axis in conjunction with the horizontal rotation of the operation unit main body. And a lifting body that can be moved up and down based on the operating force applied to the operating unit And providing the outer top member with a height adjustment mechanism on the upper surface of the main body, and providing the outer cylindrical member on the lower surface of the auxiliary top plate. Positioning means provided with an insertable / removable inner cylinder member, wherein the outer cylinder member restricts the upward movement of the operation part arranged on the upper surface of the main body part, and positions the relative position of the operation part with respect to the outer cylinder member And the outer peripheral surface of the operation portion protrudes outward from the outer surface of the outer cylinder member through a notch formed in the outer cylinder member, and the lifting body is screwed onto the screw shaft. A nut member having a female screw hole that can be engaged, and the nut member is in a free state in which it does not abut against any wall portion of the outer cylinder member before operating the operation portion. Without changing the relative height position with respect to the screw shaft, The nut member abuts against the wall portion of the outer cylinder member when the operation portion is rotated horizontally by a predetermined angle, and the horizontal rotation motion of the nut member itself is restricted, and the horizontal rotation operation of the nut member itself is restricted. In the restricted state, the nut member is screwed and raised by further horizontally rotating the operation portion in the same direction .

  If this is the case, for example, when used together with a free address table, etc., workers on the left and right sides across the furniture with the auxiliary top can share one main body and auxiliary top, Since the auxiliary top plate is detachably attached to the main body, the auxiliary top plate must be replaced according to various conditions such as the shape and color of the free address table to be used together or the preference of the office worker. This makes it possible to use various variations. As described above, various variations can be developed flexibly according to the conditions such as the use situation, and the utility becomes practical. In addition, since the height adjustment mechanism is provided in the main body, the configuration of the auxiliary top plate itself can be simplified, and various auxiliary top plates having different specifications can be easily manufactured without difficulty.

  If the auxiliary top plate is disposed so that it can be reversed in the front-rear direction, it is particularly effective when used exclusively for one worker, and the furniture with the auxiliary top plate that was initially placed on the right side of the worker Is placed on the left side of the office worker after the layout change or the like, it can be dealt with only by flipping the auxiliary top plate back and forth, which is very convenient.

  As a specific embodiment, the height adjustment mechanism includes an operation unit for performing an operation for operating the height adjustment mechanism, and a lifting body capable of moving up and down based on an operation force applied to the operation unit. What is equipped and what has mounted the said auxiliary top plate in this raising / lowering body is mentioned.

  The operation unit is integrally provided with an operation unit main body that can rotate horizontally and a screw shaft that rotates about the vertical axis in conjunction with the horizontal rotation of the operation unit main body, As long as the nut member has a female screw hole that can be screwed onto the screw shaft, it is possible to realize stepless lifting using a simple structure.

  If the height adjusting mechanism is provided at two locations on the main body, it is possible to simplify the operation.

  In addition, an outer cylinder member provided with the height adjusting mechanism is provided on the upper surface of the main body, and an inner cylinder member that can be inserted into and removed from the outer cylinder member is provided on the lower surface of the auxiliary top plate. If the bottom part is placed on the lifting body, the auxiliary top plate can be attached and detached very easily.

  In order to make the insertion / removal operation of the inner cylinder member to / from the outer cylinder member and the lifting / lowering operation of the auxiliary top plate smooth and stable, the inner cylinder member is fitted in the outer cylinder member. A gap is formed between the member and the outer cylinder member, and the inner cylinder member abuts or approaches the outer cylinder member when the inner cylinder member and the outer cylinder member move relative to each other. It is preferable to provide a slider member to be obtained.

  As a preferred embodiment, the auxiliary top plate is formed with a use edge on one side, and a drawer that can be inserted into and removed from the use top side of the auxiliary top plate between the auxiliary top plate and the main body portion. The thing which has arranged is mentioned.

  Further, in order to position the main body portion in the space below the top plate so that it can be used as a storage container under the top plate, the main body portion has a storage space inside, and this storage space It is desirable to form an opening that can open the left and right sides.

  If the furniture with an auxiliary top plate of the present invention is used in combination with, for example, a table for a free address, the workers on the left and right sides of the furniture with the auxiliary top plate can share not only the auxiliary top plate but also the main body, and use it together. The auxiliary top plate can be freely exchanged according to the shape and color of the free address table or the preference of the office worker, etc., and a variety of usage modes are possible. Furthermore, by providing a height adjustment mechanism in the main body, the configuration of the auxiliary top plate itself can be made relatively simple, and it is easy to manufacture and provides various types of auxiliary top plates of different types.

The lower end of the portion 622 is brought into contact with the outer cylinder elements 61 and 62 so that the upper ends of the outer cylinder elements 61 and 62 are at substantially the same height. In this assembled state, the side wall 612 of the first outer cylinder element 61 and the side wall 622 of the second outer cylinder element 62 are in close contact with each other, and the inner wall 613 of the first outer cylinder element 61 and the second outer cylinder element The inner wall portion 621 of 62 is in close contact. In addition, in this assembled state, a region excluding a part of the inner wall portion 621 of the second outer cylinder element 62 is covered with the first outer cylinder element 61 (see FIG. 6). The outer cylinder member 6 formed by assembling the pair of outer cylinder elements 61 and 62 in this manner has a depth in a lower end region at a substantially central portion in the width direction via the notches 611a and 621a provided in the outer cylinder elements 61 and 62. It has a space that communicates in the direction and has an inner space that opens upward. As described above, the outer cylinder member 6 is integrally provided with the height adjusting mechanism 5.

  As shown in FIG. 4 and the like, the height adjustment mechanism 5 is an operation unit 51 for performing an operation for operating the height adjustment mechanism 5, and the present invention can be moved up and down based on an operation force applied to the operation unit 51. And a nut member 52 which is a lifting body.

  The operation unit 51 is integrally provided with an operation unit main body 511 that can rotate horizontally and a screw shaft 512 that rotates about the vertical axis in conjunction with the horizontal rotation of the operation unit main body 511. The operation portion main body 511 has a substantially columnar shape having a diameter slightly smaller than the distance between the distal end portions of the bottom portion 614 of the first outer cylinder element 61, and is provided with a notch provided in each of the outer cylinder elements 61 and 62. The height dimension is slightly smaller than 611a and 621a. A wavy uneven portion 511a is continuously provided in a predetermined region of the outer peripheral surface of the operation portion main body 511. The screw shaft 512 protrudes upward from a substantially central portion on the upper surface of the operation unit main body 511, and a male screw is cut on the outer peripheral surface. The diameter of the screw shaft 512 is set to be slightly smaller than the diameter of the through hole 623 a provided in the contact portion 623 of the second outer cylinder element 62.

  The nut member 52 is provided with a round pipe-shaped nut main body 521 having a female screw hole 52a that can be screwed into the screw shaft 512, and a part of the inner cylinder member 7 described later provided on the lower end side of the nut main body 521. A substantially rectangular plate-like mounting surface portion 522 is integrally formed. The outer diameter of the nut main body 521 is set larger than the diameter of the through hole 623 a provided in the contact portion 623 of the second outer cylinder element 62. The mounting surface portion 522 is a substantially plate-like one that extends a predetermined dimension in the width direction with the nut body 521 as the center, and the depth dimension and the width dimension are the outer dimensions formed by assembling the pair of outer cylinder elements 61 and 62. It is set smaller than the depth dimension and the width dimension of the cylindrical member 6. Specifically, the depth dimension of the placement surface portion 522 is set to be smaller than the separation distance between the outer wall portion 611 of the first outer cylinder element 61 and the inner wall portion 621 of the second outer cylinder element 62, and The width dimension is set smaller than the separation distance between the side wall portions 622 of the second outer cylinder element 62. Both side edges of the mounting surface portion 522 are appropriately processed so as to have a gentle roundness.

  Next, a procedure for attaching the height adjusting mechanism 5 to the outer cylinder member 6 formed by assembling the outer cylinder elements 61 and 62 by the above-described procedure will be described. First, using the space communicated in the depth direction through the notches 611a and 621a formed at the lower ends of the outer cylinder elements 61 and 62, the operation unit 51 is partially exposed. It is accommodated in the outer cylinder member 6. At that time, the screw shaft 512 of the operation portion 51 is inserted into the through hole 623 a provided in the contact portion 623 of the second outer cylinder element 62. Subsequently, the nut member 52 is brought from above so that the female screw hole 52a of the nut main body 521 is aligned with the screw shaft 512, and the screw shaft 512 and the female screw hole 52s are screwed together, whereby the nut member 52 is moved to the operation portion. It moves in a direction approaching the main body 511. When the nut member 52 is screwed downward to some extent, the lower end of the nut body 521 comes into contact with the contact portion 623 of the second outer cylinder element 62, and further screwing operation is restricted. At this time, by setting the outer diameter of the nut main body 521 to be larger than the diameter of the through hole 623a, it is possible to reliably prevent the nut member 52 from further screwing. Thus, the contact portion 623 of the second outer cylinder element 62 functions as a restricting means that restricts the downward movement of the nut member 52. Further, the contact portion 623 also regulates the upward movement of the operation portion 51 and also serves as a positioning means for positioning the relative position of the operation portion 51 with respect to the outer cylinder member 6.

  In order to attach the outer cylinder member 6 integrally incorporating the height adjusting mechanism 5 to the front end portion and the substantially middle portion in the depth direction on the upper surface of the main body 2 by the above procedure, the outer cylinder member 6 in the upper plate 23 is previously provided.

  As shown in FIGS. 4 to 6 and the like, the inner cylinder member 7 is formed by bending a sheet metal material, for example, and has substantially the same height as the outer cylinder member 6. Specifically, the outer wall portion 71 having a width smaller than the inner wall portion 621 of the second outer cylinder element 62, side wall portions 72 formed by bending both end portions of the outer wall portion 71 substantially at right angles, and the respective side wall portions 72. The inner wall 73 is formed by bending one end of each of the two in a direction in which they are close to each other. The upper end portion of each side wall portion 72 is bent in a direction away from each other, and a tongue-like placement surface portion 74 on which the auxiliary top plate 3 can be placed is provided. In addition, a pair of slits are formed in the vicinity of both side end portions of the outer wall portion 71 along the height direction from the lower end, and a bottom portion 75 is formed by bending a portion located between the slits so as to be substantially horizontal. A folded portion 76 is formed by folding the tip of the bottom portion 75 further upward. The width dimension of the bottom part 75 and the folding | returning part 76 is set so that it may respond | correspond substantially to the separation distance between the front-end | tip parts of the inner wall part 73, and it sets so that the folding | turning part 76 and the inner wall part 73 may become substantially flush | planar. Yes. An insertion hole 75 a having a diameter through which the screw shaft 512 of the operation unit 51 and the nut main body 521 of the nut member 52 can be inserted is formed in a substantially central portion of the bottom portion 75. A long hole 74a penetrating in the thickness direction is formed at a predetermined position of each mounting surface portion 74. In addition, two round holes 7a are intermittently formed in the vicinity of both end portions of the outer wall 71 along the height direction, and the slider member 8 is attached to each round hole 7a. The slider member 8 is made of, for example, a synthetic resin, and is formed by integrally forming a head 81 having a substantially partial spherical shape and a shaft portion 82 that can be inserted into the round hole 7a. The slider member 8 is attached to the round hole 7a by press-fitting the shaft portion 82 of the slider member 8 into the round hole 7a. Similarly, two round holes 7a are intermittently formed in the side wall portion 72 and the inner wall portion 73 along the height direction, and the slider member 8 is attached to each round hole 7a. In order to attach the inner cylinder member 7 to the front end portion and the rear end portion of the auxiliary top plate 3, an insert nut (not shown) embedded in the attachment portion of the inner cylinder member 7 on the lower surface of the auxiliary top plate 3 in advance is mounted. This is performed by matching the long hole 74a provided in the surface portion 74, inserting an appropriate bolt V from below into the long hole 74a, and subsequently screwing it into the insert nut (see FIG. 7). In this way, the inner cylinder member 7 is integrally provided at the front end portion and the rear end portion of the auxiliary top plate 3. At this time, the pair of inner cylinder members 7 are attached so that the inner wall portions 73 of the inner cylinder member 7 face each other, and the outer wall portion 71 of the inner cylinder member 7 can be seen from the front and back surfaces of the auxiliary top plate 3. To do. In the present embodiment, one side of the auxiliary top plate 3 is set as the use edge 31, which is the lower surface of the auxiliary top plate 3 and between the pair of inner cylinder members 7. A drawer 4 that can be taken in and out is provided.

  The drawer 4 is fixed to the lower surface of the auxiliary top plate 3 and has a rectangular box-like casing 41 that opens to the use edge 31 side of the auxiliary top plate 3. The drawer 4 is set to be accommodated in the casing 41 and is used for the upper and auxiliary top plates 3. A drawer main body (not shown) having a rectangular box shape opening to the edge 31 side and a mirror plate 43 provided integrally at a position for closing the opening on the use edge 31 side of the auxiliary top plate 3 in the drawer main body are provided. A handle 431 that can be gripped at the time of operation is provided at a substantially central portion of the end plate 43. The height dimension of the drawer 4 is set smaller than the height dimension of the inner cylinder member 7 so that the drawer 4 and the main body 2 do not interfere when the auxiliary top plate 3 is attached to the main body 2.

  Next, a procedure for attaching the auxiliary top plate 3 to the main body 2 will be described. First, the front-rear direction of the auxiliary top plate 3 is determined in consideration of the direction in which the drawer 4 is put in and out, and the inner cylinder member 7 provided on the lower surface of the auxiliary top plate 3 is changed to the outer cylinder member 6 provided in the main body 2.
