Description

  The present invention relates to a table that can be easily assembled.

  There are various types of desks, but a structure in which the left and right legs are supported by a top board is common. For example, as described in Patent Document 1, a curtain plate is attached to the back of the legs. There are many things. Moreover, as described in Patent Document 1, there are many cases in which one or both sides of the top plate are supported by a sleeve drawer.

  On the other hand, in Patent Document 2, the legs can be used face-to-face by supporting the separate top plates with the front and rear arms, with the arms (supporting arms) protruding from the upper end of the pedestal to the front and rear. In such a desk, an apparatus that can be connected by an arbitrary number of units is disclosed.

Patent Document 3 discloses that a plurality of top plates are arranged on the left and right or front and back and connected to each other so that legs are arranged so as to straddle adjacent top plates. Then, it is described that one leg is shared by the adjacent top plates.
Japanese Patent No. 3326678 Japanese Examined Patent Publication No. 62-54487 Japanese Utility Model Publication No. 62-20524

  Although the curtain plate is widely attached to the back of the desk as in Patent Document 1, the curtain plate is provided for shielding. In a normal desk, the top plate and the legs are connected to each other. A curtain is installed. In other words, the normal desk secures the overall rigidity by firmly connecting the top plate and the legs.

  Well, the desk is a single-sided type where one person sits only on one side, a double-sided type where a person sits facing each other, a single type where only one person sits on one side of the top board, and a common type where multiple people can sit on one side of the top board As such, there are various types, so manufacturers need to enrich their assortment.

  Conventionally, dedicated members are prepared and assembled for each type of desk, and therefore, when viewed as a whole of the desk group, various costs such as processing cost, management cost, transportation cost, etc. are increased and required for processing The amount of energy used, such as energy, energy required for transportation, and energy required for disposal after disposal, tends to increase, and there is a problem that the environmental load is large.

  In order to solve this problem, the applicant of the present application disclosed in Japanese Patent Application No. 2003-139458 in a desk that supports a top board with a support such as a leg or sleeve drawer, and the desk is made up of a top board, a support, and a back frame. As a configuration, it has been proposed to reduce the manufacturing cost and energy consumption of the entire desk group as much as possible by unitizing the top plate, the support, and the back frame so as to be shared by a plurality of types of desks.

  By the way, there are cases where wiring space is required at the rear of the desk, and there are cases where it is not necessary as a user who uses the desk, and in the case of a double-sided desk used by people facing each other, the front and rear top plates are There is a case where the user wants to have a single plate-like form, and a case where a space (for example, a wiring space) is left between the front and rear top plates. That is, there is a desire to change the front and rear position of the top board. However, the front and back positions of the top plate are constant in the conventional desk, and therefore, it is necessary to manufacture a plurality of types of desks in order to meet the user's request. Occurs.

  The present invention has been made in view of such a situation, and it is an object of the present invention to provide a user-friendly desk in a state in which cost and consumption ergies are suppressed as much as possible while following the idea of the prior application. is there.

  The present invention includes, as a premise, a top plate, left and right supports that support the top plate, and a back frame that is disposed so as to overlap the rear portions of the left and right supports, and the top plate The back frame and the back frame are connected to each other and the left and right supports, respectively, and the back frame is a strength member.

  In the first aspect of the invention, as a feature, the back frame is provided with connecting means capable of connecting the support body on both front and rear surfaces thereof, and the top plate has a rear end portion overlying the rear of the back frame. Can be connected to the leg in a hung state.

  According to a third aspect of the present invention, in the first or second aspect, the top plate has a forward position positioned before the rear surface of the leg so that a wiring space is provided between the rear end surface and the back frame, and a rear end surface of the top plate. It is possible to connect to the leg by selecting three positions: an intermediate position substantially coincident with the rear surface of the back frame and a retracted position where the rear end portion overhangs behind the back frame.

  According to a fourth aspect of the present invention, in the second or third aspect, the back frame is provided with coupling means capable of coupling a support to both front and rear surfaces.

  According to the first aspect of the present invention, a desk with the top plate overhanging behind the back frame can be provided. However, since the back frame is a strength member, the table is shared with the desk with the top plate not overhanging. A desk that does not overhang is only required to have a different mounting position of the top plate with respect to the legs, and the support frame can be connected to both the front and back sides of the back frame. You can also use it. For this reason, it is possible to enrich the assortment of desks while suppressing manufacturing costs and energy consumption as much as possible.

  According to the second aspect, since the front and rear positions of the top plate can be changed in one desk, it is possible to more accurately meet the user's request. Furthermore, if comprised like Claim 3, since the front-back position of a top plate can be adjusted in three steps, usability can be improved more. In addition, in Claim 2, it can also be set as the structure which adjusts the front-back position of a top plate in a stepless manner.

  When configured as in claim 4, the members can be shared between the single-sided desk and the double-sided desk, and for example, a state in which a wiring space is vacated between the front and rear top plates and the front and rear top plates are abutted It is possible to select and is easy to use.

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

(1). Outline of First Embodiment FIGS. 1 to 11 show a first embodiment. 1A is a schematic perspective view of a double-sided desk, FIG. 1B is a separated perspective view of a double-sided desk, and FIG. 3 is a double-sided desk. FIG. 4 is a side view in a state as a single-sided desk.

  As shown in these drawings, the desk is composed of two top and bottom top plates 1 formed in a rectangular shape (horizontal rectangle) in plan view, and a total of four legs 2 as a pair of left and right as an example of a support, as main members. And one back frame 3.

  The top plate of the present embodiment is made of wood (of course, it may be made of other materials such as steel), a melamine resin layer is provided on the upper surface, and an edge made of synthetic resin or the like is fixed to the periphery. Although not shown, a drawer is provided on the lower surface of the top plate 1. 1 to 3, a wiring space 5 is vacant between the top plate 1 and the back frame 3.

  The leg 2 is made of a metal plate (made of steel), and includes a vertically long leg column part 6, a lower arm part 7 extending forward from the lower part thereof, and an upper arm part 8 extending forward from the upper end part of the leg pillar part 6. It is formed in a substantially U-shape (obviously, other forms may be used). The legs 2 are disposed at positions that enter the inside by a slight dimension from the left and right outer surfaces of the top plate 1 and the back frame 3. An adjuster bolt 9 is provided on the lower surface of the leg 2.

  The back frame 3 is made of a metal plate, and is formed in a rectangular shape (rectangular shape) when viewed from the front and back by a vertically long left and right side member 10 and a horizontally long upper member 11 and a lower member 13 constituting the outer periphery. The upper surface of the back frame 3 and the upper surface of the leg 2 are set at the same height. Further, the lower surface of the back frame 3 is located at a height higher than the floor by a certain amount. A separate back panel 12 can be detachably attached to the back frame 3.

  The width dimension of the back frame 3 is set to the same dimension as the width dimension of the top plate 1. For this reason, a plurality of desks can be juxtaposed in a state where the top plate 1 and the back frame 3 are in close contact with each other (or in close contact). The back frame 3 may be disposed below the upper surface of the leg 2. In addition, the back frame 3 of the present embodiment is formed in a frame shape opened in the front-rear direction. In this case, it is preferable that the blindfold curtain plate is attached detachably or non-removably.

(2). Connection Structure of Back Frame and Leg Next, a connection structure of the back frame 3 and the leg 2 will be described with reference to FIGS. 5 is an exploded perspective view of the back frame 3 and the leg 2, FIG. 6 is a partial plan view of the top plate 1 indicated by phantom lines, FIG. 7A is a longitudinal side view of the rear part of the leg 2, and FIG. ) Is an enlarged view of a portion indicated by an arrow B in (A), and (C) is an enlarged view of a portion indicated by an arrow C in (A).

  As shown in FIG. 5, the upper member 11 and the lower member 13 of the back frame 3 are hollow and have a front plate and a back plate, have a substantially C-shaped cross section, and have a lip 14 at the leading edge. Arranged in an inward posture. The side member 10 is formed in a hollow shape having a front plate and a back plate and having a U-shaped cross section that opens inward. Needless to say, the shape of each member can be arbitrarily selected.

  The left and right end portions 11a, 13a of the upper member 11 and the lower member 13 cover the upper and lower end portions of the side member 10, and the portions where the members overlap each other are fixed by welding such as spot welding. A window hole 3a for inserting a welding probe is provided in the upper and lower portions of the left and right outer plates of the side member 10 (see FIGS. 1 to 4).

  For example, as can be easily understood from FIG. 5, the pedestal column portion 6 is formed in a hollow shape, and a pair of left and right first openings opened upward at the upper end portion of the rear plate 6 a constituting the rear end of the pedestal column portion 6. On the front surface of the side member 10 in the back frame 3 just below the end portion 11a of the upper member 11, a neck portion 18 fitted from above into the first slit groove 17 is formed. A first protrusion 20 having a larger-diameter head portion 19 is fixed with a screw 21.

  In addition, a pair of left and right second slit grooves 22 opened downward are formed in the left and right end portions 13a of the lower member 13 of the back frame 3 that overlap with the legs 2, while the rear plate 6a of the leg 2 has A second protrusion 23 having a neck portion 18 fitted into the second slit groove 22 from below and a head portion 19 having a larger diameter than the neck portion 18 is fixed by a screw 21. The first protrusion 20 and the second protrusion 23 are of the same type, and the both cut grooves 17 and 22 are the same in shape and size.

  The second slit groove 22 and the second protrusion 23 are arranged symmetrically on both front and rear surfaces of the back frame 3. Therefore, by attaching the legs 2 to both front and rear surfaces of the back frame 3, a desk in which the two top plates 2 are arranged back to back can be configured. Of course, as shown in FIG. 4, it is possible to attach a leg 2 to only one side of the back frame 3 to constitute a single type desk having only one top plate 1.

  When connecting the back frame 3 and the leg 2, the pair of left and right legs 2 are positioned so that the back frame 3 is sandwiched between the front and rear legs 2, and then the back frame 3 is overlapped on the back of the left and right legs 2. The slits 17 and 22 and the protrusions 20 and 23 may be fitted together by sliding downward in the above state. For this reason, a connection operation can be performed easily. The slits 17 and 22 have wide openings so that the protrusions 20 and 23 can be easily guided.

  A reinforcing plate 24 is welded in the hollow portion of the rear portion of the leg 2 in a state of being slightly lower than the upper end surface of the leg 2, and the second plate 6a is interposed between the reinforcing plate 24 and the rear plate 6a. There is a gap through which one projection 20 can pass. Further, a restricting body 25 made of a plate material that prevents the first protrusion 20 from moving upward is fixed to the reinforcing plate 24 with screws 26. For this reason, even if an upward force is applied to the back frame 3 such as lifting the back frame 3 when the desk is moved, the connection between the back frame 3 and the leg 2 is not released.

  In the present embodiment, the protrusions 20 and 23 are fixed with screws 21. However, it is also possible to integrally form a male screw part on the protrusions 20 and 23, or to use a headed bolt for the protrusion. In addition, the protrusions 20 and 23 are not necessarily circular, and may be formed in a rectangular shape in front view with a convex shape in plan view, for example.

  The connecting means between the back frame 3 and the leg 2 can adopt various modes. However, as in this embodiment, the back frame 3 is overlapped on the rear surface of the leg 2 and slid downward, and the projections 20 and 23 and the slit groove Adopting a configuration that fits 17 and 22 has an advantage that the connecting operation can be easily performed.

(3). Connecting Structure of Top Plate and Leg Next, a connecting structure of the top plate 1 and the leg 2 will be described with reference to FIGS. 8 to 10 in addition to FIGS. 8 is an exploded perspective view showing the connection structure between the top board 1 and the legs 2. FIG. 9A is a sectional view taken along the line IXA-IXA in FIG. 6, and FIG. A schematic front view of a desk supported by two legs 2 (intermediate legs), (C) is a cross-sectional view of the main part of the desk of (B), and (A) of FIG. The figure (top plate 1 is displayed with a dashed-dotted line), (B) is the elements on larger scale of (A), (C) is CC sectional view taken on the line of (B).

  The upper arm portion 8 of the leg 2 has a bowl-like shape opened upward, and has an inward lip 8a at the upper end, and its rear portion is fixed to the inner surface of the leg column portion 6 by welding. A pair of front and rear lower engagement bodies 28 are fixed to the upper arm portion 8 with screws 29, and a pair of front and rear upper engagement bodies engaged with the lower engagement body 28 are provided on the lower surfaces of the left and right end portions of the top plate 1. 30 is fixed with screws 31. In order to attach the lower engagement body 28, the lip 8a of the upper arm portion 8 is partially cut away.

  The upper engagement body 30 is made of a metal plate and has a substantially L-shape when viewed from the front, and the horizontal portion is fixed to the top plate 1 with screws 31. The top plate 1 has a demon nut 32 into which a screw 31 is screwed. The vertical portion 30a of the upper engagement body 30 is formed with an upward upward engagement claw 33 in a side view and an upward positioning projection 35 that fits into a positioning hole 34 provided in the top plate 1. The upper engagement claw 33 is directed forward in the upper engagement body 30 at the front, and the upper engagement claw 33 is directed rearward in the upper engagement body 30 in the rear (the upper engagement body 30 The claw 33 may be reversed.)

  The lower engagement body 28 is made of a synthetic resin, and has a base portion 28a that overlaps the bottom surface of the upper arm portion 8, a block-like positioning portion 8b that rises from the base portion 28a, and on the opposite side of the positioning portion 28b across the space. A pair of left and right lower engaging claws 36 are provided, and a pair of left and right positioning grooves 37 are formed in the positioning portion 28b with an upward opening into which the vertical portion 30a of the upper engaging body 30 is fitted. The upper end of the positioning groove 37 is formed in a tapered shape that spreads upward in a front view in order to attract the vertical portion 30 a of the upper engagement body 30.

  The lower engagement claw 36 is formed in a side face shape so that the upper engagement claw 33 meshes, and the front lower engagement body 28 is in a posture in which the lower engagement claw 36 faces rearward, The lower engagement body 28 is in a posture in which the lower engagement claw 36 faces forward.

  After positioning the left and right legs 2, the top plate 1 is pressed downward, and the engaging claws 33 and 36 of the upper and lower engagement bodies 28 are fitted against each other, thereby connecting the top plate 1 and the legs 2. Is done. And the top part 1 is hold | maintained in the state which does not rattle in the left-right direction by the vertical part 30a of the upper engagement body 30 fitting in the positioning groove 37 of the lower engagement body 28. FIG. Further, since the engaging claws 33 and 36 of the upper and lower engaging bodies 28 and 30 are reverse in the front-rear direction, the top plate 1 is held so that it cannot be displaced forward and backward.

  In a state where the top plate 1 is connected to the leg 2, the horizontal portion of the upper engagement body 30 overlaps the upper surface of the leg 2. Therefore, the thickness of the upper engagement body 30 is between the top plate 1 and the leg 2. The gap 4 having the same dimensions as that is vacant.

  When only one top plate 1 is supported by the left and right legs 2, the upper engagement claw 33 is engaged with the lower engagement claw 36 on the outer side of the lower engagement body 28 as shown in FIG. 9. On the other hand, as shown in FIG. 7 (B), in the case of a continuous type in which two top plates 1 are supported by one leg (intermediate leg) 2, as shown in FIG. The upper engagement claw 33 is engaged with the lower engagement claw 36 of the lower engagement body 28. Therefore, the vertical portion 30a of the upper engagement body 30 and the distance L1 between the upper engagement body 30 and the outer surface of the top plate 1 are half the distance L between the lower engagement claw 36 and the positioning groove 37 in the lower engagement body 28. It has become.

  A mode in which only one top plate 1 is supported by providing a pair of left and right positioning grooves 37 and lower engagement claws 36 in the lower engagement body 28, and a type in which a plurality of top plates 1 are provided side by side. Can be shared with The positioning means for holding the upper engagement body 30 so as not to be laterally displaced is not limited to the positioning groove as in the embodiment, and other methods can be employed. Moreover, the form of the vertical engagement claws 33 and 36 can be variously embodied.

(4). Front / rear position changing means of the top plate A pair of front and rear lower engaging bodies 28 are arranged on the leg 1, while the top plate 1 is provided with front / rear positions of the demon nut 32 (screw hole) and the positioning hole 34. Three pairs are formed in a state where the pairs are shifted in the front-rear direction, so that the attachment position of the front-rear upper engagement body 30 can be selectively fixed by shifting to three positions along the front-rear direction. Yes.

  Further, in a state where the pair of the upper engagement bodies 30 is located at the backmost position (position a in FIG. 10), the wiring space 5 is vacant between the rear surface of the top plate 1 and the back frame 3. 4 is in the middle portion (position b in FIG. 10), the rear surface of the top plate 1 and the rear surface of the back frame 3 are substantially in the same plane as shown in FIG. In a state where the pair is positioned on the near side (position c in FIG. 10), the rear end portion of the top plate 1 is set to overhang behind the back frame 3.

  In any aspect, the desk can select an aspect in which the top plate 1 is provided only on one side of the back frame 3 and an aspect in which the top plate 1 is provided on both front and rear sides of the back frame 3. As shown in FIG. 4A, when the top plate 1 and legs 2 indicated by solid lines and the top plate 1 and legs 2 indicated by alternate long and short dash lines are provided, the front and rear engaging bodies 1 are continuous in a single plate shape.

  Further, as shown in FIG. 4B, the top plate 1 indicated by a solid line is overhanged behind the back frame 3, and the top plate 1 indicated by a one-dot chain line is shifted to the front side to thereby make a double-sided type desk. It is also possible to shift the position of the top plate 1 in the front-rear direction. As shown by a two-dot chain line in FIG. 4B, several types of top plates 1 having different front and rear width dimensions are prepared as a unit and can be changed according to the user's request.

  In this embodiment, the position of only the upper engagement body 30 is changed. For example, the front and rear upper engagement bodies 30 are integrally formed through the plate portion, and the front and rear longitudinal elongated holes are formed in the plate portion. Thus, by screwing the screw inserted into the elongated hole into the top plate 1, the mounting position of the upper engagement body 30 can be adjusted steplessly.

  It is also possible to change and adjust the position of only the lower engagement body 28 stepwise or steplessly, or to adjust both the upper and lower engagement bodies 38 and 30 stepwise or steplessly. .

  The top plate 1 can also be fixed at a position where the rear end surface is substantially flush with the rear surface of the leg 1. In this case, a space that is the same as the thickness of the back and forth of the back frame 3 is vacant behind the top plate 1, but this space can also be used as a wiring space.

(5). Variation As described above, the back panel 15 can be attached to the back frame 1 when the back frame 3 is exposed upward. As one of the attachment methods, as shown in FIG. 11, a plurality of support holes 46 are provided at appropriate locations such as the left and right ends of the back frame 3, and a foot bar 47 protruding downward from the back panel 39 is provided. It is conceivable to fit into the support hole 46. In addition, when the back frame 3 is exposed upward, the back frame 3 can be exposed above the top plate 1, and a back panel can be comprised by the exposed part.

  By the way, it is widely performed that the desks are arranged side by side with the back frames in close contact with each other. In such a layout, it is preferable to connect the back frames 3 adjacent to each other on the left and right. FIG. 12 shows an example of a method for connecting back frames.

  In the example shown in (A), utilizing the fact that the welding window hole 3a is vacant on the outer plate of the side member 10, the hairpin-shaped clip 55 is attached to the side members 10 at the position of the window hole 3a. The outer plate is clamped elastically. On the other hand, in the example shown in (B), adjacent side members 10 are fastened with bolts (screws) 56. It is also possible to form a slit that opens vertically on the left and right ends of the upper surface plate of the upper member 11 and to connect by inserting a clip 55 similar to (B) into a slit adjacent to the left and right.

(6). Modifications The top plate 1 is not necessarily supported by the legs 2, but may be supported by a sleeve drawer (wagon) 48 on one side or both sides as shown in FIG. In this case, as shown in FIG. 13B, in order to connect the back frame 3, the first slit groove 17 and the first protrusion 20 may be provided on the rear plate 48 a of the sleeve drawer 48. Further, although not shown, for connection with the top board 1, the lower engagement body 28 may be fixed to the upper surface of the end of the sleeve drawer 48 on the left and right outer sides.

  It is also possible to support two top plates 1 adjacent to each other on the left and right with the sleeve drawer 48. In this case, the first slit 17 and the first protrusion 20 are on both sides of the center line dividing the left and right. What is necessary is just to arrange | position and the lower engagement body 28 should just be provided in the site | part along the centerline divided into right and left.

(7). Other embodiments (FIGS. 14 to 15)
In FIG. 14, 2nd Embodiment which is another example of the front-back position adjustment means of the top plate 1 is shown. (A) is a longitudinal front view of the main part, (B) is a BB plan sectional view of (A).

  In this embodiment, a longitudinally long guide body 50 having a bowl-like shape with an upward opening and an outward flange at the upper end is fixed to the lower surfaces of the left and right side portions of the top plate 1, and the guide body 50 is fixed to the leg 2. The upper arm portion 8 is fitted in the hollow portion so as to be movable back and forth. The bottom plate of the guide body 50 is formed with a longitudinally long slot 51, and a screw 52 that passes through the bottom plate of the upper arm portion 8 from below and is inserted into the slot 51 is rotated inside the guide body 50. It is screwed into a square nut 53 that is impossible to fit. The flange of the guide body 50 is fixed to the top plate 1 with a countersunk screw.

  In this embodiment, the front-rear position of the top board 1 can be adjusted steplessly. However, if the screw 52 is loosened, the top plate 1 may move back and forth unexpectedly due to external force. In order to prevent this, positioning means may be provided so that it can be changed step by step.

  FIG. 15 shows an example in which the back frame 3 is disposed between the left and right legs 2. (A) is a single-sided desk having only one top plate 1, and the rear surface of the back frame 3 and the rear surface of the legs 2 form substantially the same surface. On the other hand, the example shown in (B) is a double-sided desk having two front and rear top plates 1, and the front and rear legs 2 are overlapped by half on the left and right side surfaces of the back frame 3.

  As a connecting method when the back frame 3 is arranged between the left and right legs 2 in this way, in the example shown in (C), the legs 2 are fixed to the back frame 3 with screws (bolts) 54, In the example shown in (D), the combination of the headed projections 20 and 23 and the slit groove is adopted as in the first embodiment.

(8). Others The present invention can be embodied in various ways other than the above embodiment. For example, the connecting means between the back frame and the leg is not limited to the illustrated one, and various methods can be adopted. The back frame may be formed in, for example, a hollow plate shape that is entirely closed. In the case of a double-sided desk in which legs are arranged on both the front and rear sides of the back frame, it is also possible to connect a single top plate straddling the front and rear legs so that the front and rear positions can be adjusted.
