For example, the back plate 3 can be attached to a higher position with respect to the leg 1.

  In the above, the upward fixed pawl 121 and the upward movable pawl 122 are paired, and the hook holes 201 and 202 of the top plate 2 are also paired. Therefore, when the leg 1 is used as an end leg, As shown in FIG. 13, the pair of upward fixed claws 121 and upward movable claws 122 are arranged so that the side end surfaces of the top plate 2 do not protrude sideways from the legs 1 by engaging the hook holes 201 and 202 with each other. However, when used as an intermediate leg, as shown in FIGS. 14 to 15, the left and right top plates 2 and 2 are placed on the top 1 and placed on the top plate support 1x and fixed upward. By engaging the claw 121 and the upward movable claw 122 in half with the nearest hook holes 201 and 202 of each top plate 2, the usage mode can be changed without adding any members. As described above, since the hook holes 201 and 202 are gradually narrower in the direction in which the fixed claws 121 and the movable claws 122 are engaged, the fixed claws 121 and the movable claws 122 are formed in the hook holes 201 and 202. As it bites in, the left and right top plates 2 and 2 are pulled in the width direction and can be strongly connected. Similarly, the rearward movable claw 112 and the rearward fixed claw 111 are paired, and the hook holes 302 and 301 of the back plate 3 are also paired. Therefore, when the leg 1 is used as an end leg, FIG. 13, the claws 112 and 111 are engaged with the hook holes 302 and 301 so that the side end surface of the back plate 3 does not protrude sideways from the leg 1, but the back surface is not the inner surface of the leg 1. Although it is attached to the plate holder 1y, when used as an intermediate leg, as shown in FIGS. 14 to 15, the left and right back plates 3, 3 are attached to the back plate holder 1y of the leg 1 in half halves. By installing and engaging the claws 112 and 111 with the nearest hook holes 302 and 301 of the respective back plates 3 by half, the usage mode can be changed without adding any members.

  As described above, in the top plate mounting structure according to this embodiment, when the top plate 2 is attached to the top plate receiver 1x having the long stay portion 12 at least on the front end side, the top plate is projected upward from the top plate receiver 1x. An upward fixed claw 121 serving as a first top plate engaging portion and an upward movable claw 122 serving as a second top plate engaging portion are provided, and the hook holes 201 and 202 which are provided on the lower surface of the top plate 2 are directed upward. By inserting the fixed claw 121 and the upward movable claw 122 and moving them relative to each other, the claw 121 and 122 are engaged with the opening edges of the hook holes 201 and 202 to attach the top plate 2 to the top plate receiver 1x. Is.

The stay 12 is provided with a top plate mounting drive mechanism 4 for relatively moving the upward fixed claws 121 and the upward movable claws 122 in contact with and away from each other.
In this way, the one that uses the relative contact and separation of the upward fixed pawl 121 and the upward movable pawl 122 is easy to operate, but has an appearance on a desk or the like in order to arrange the top plate mounting drive mechanism. However, if the top plate mounting drive mechanism 4 is installed in the stay portion 12 as in this embodiment, the screw member 42 and the like will not be exposed. In addition, it is possible to effectively realize a top plate mounting structure that can be easily attached and detached without impairing the appearance of the legs 1 and the like. And since the components which comprise a drive mechanism are integrated, construction of the furniture with a top plate, etc. becomes possible, without losing these.

  In this case, the stay portion 12 includes an outer upper reinforcing member 120a and a second inner upper reinforcing member 120c that partially form a hollow portion, and the top plate mounting drive mechanism 4 is disposed in the hollow portion. The upward fixed claw 121 and the upward movable claw 122 are associated with the top plate mounting drive mechanism 4 so as to move relative to each other within the reinforcing members 120a and 120c. Thus, it is possible to obtain an appropriate scaffold and guide portion, and it is possible to reliably input a fixing force through a smooth contact / separation operation between the upward fixed claws 121 and the upward movable claws 122.

  Specifically, the top plate mounting drive mechanism 4 includes a screw member 42 extending along the longitudinal direction of the stay portion 12, and the screw member 42 is engaged with the movable claw 122 which is one top plate engaging portion. Since the screw member 42 is configured to be screw-fed together, the screw member 42 can be easily disposed along the longitudinal direction of the stay portion 12, and a high driving force can be obtained with a light operation force by utilizing the original function of the screw feed. Obtainable.

  And since the rotational force input end 42x for rotating the screw member 42 is exposed from the stay part 12 along the front or diagonally forward of the screw member 42, it can be operated from the front or diagonally forward. It is possible to work from the front with the top plate 2 placed on the top plate receiver 12x, and it is possible to ensure good workability.

  In this case, the screw member 42 is provided with a rotational force input end 42x on the head portion 42a, and is configured to screw-feed the upward movable claw 122 by rotating with a part thereof pressed against the retainer 43. In addition, a shutter 44 is detachably disposed in the stay portion 12 adjacent to the head portion 42a, and the shutter 44 is provided with an opening window 44a for opening the rotational force input end 42x forward. That is, when the screw member 42 is loosened, if the entire screw member 42 is moved forward by receiving a reaction force, a substantial screw feeding function for the upward movable claw 122 cannot be exhibited. Since the axial center position of the screw member 42 is kept constant, the upward movable claw 122 can be accurately screwed by the rotational force input to the rotational force input end 42x.

  Further, when the upward fixed claw 121 is in a fixed position and engages with the hook hole 201 of the top plate 2, positioning with respect to the top plate 2 is performed, and the upward movable claw 122 bites into the hook hole 201 of the top plate 2. Since it is configured to engage, when the desk 2 is connected horizontally, the use edge and the anti-use edge between the top plates 2 and 2 are surely aligned by the upward fixing claw 121, and even with a simple connection work A good-looking layout can be easily realized. Since the top plate mounting drive mechanism 4 can be compactly incorporated around the upward movable claw 122 regardless of the distance between the upward fixed claw 121 and the upward movable claw 122, the design for suppressing bulkiness is facilitated. .

  Further, the stay portion 12 constitutes a U-shaped leg 1 in side view together with the leg side plate 11 and the base portion 13, and in particular, the top plate mounting drive mechanism is easily exposed to the outside in such a leg. Therefore, application of this embodiment greatly improves the conventional problems.

  And if such a top-plate attachment structure is utilized, the furniture with a top plate which can perform attachment and detachment of the top plate 2 easily and appropriately, without impairing an external appearance can be provided.

  On the other hand, the attachment structure of the back plate according to the present embodiment includes a leg side plate 11 having an outer vertical reinforcing member 110a and a second inner vertical reinforcing member 110c that form a hollow portion in at least a part of the rear end side. When attaching the back plate 3 to the rear side, the rear fixed claw 111 as the first back plate engaging portion and the rear movable claw 112 as the second back plate engaging portion projecting rearward from the leg side plate 11 are provided. By inserting the rearward fixed claws 111 and the rearward movable claws 112 into the hook holes 301 and 302 which are openings provided on the front surface of the back plate 3 and moving them relative to each other, both the claws 112 are engaged with the opening edges of the hook holes 301 and 302. In addition, the back plate 3 is attached to the rear surface of the leg side plate 11. A back plate mounting drive mechanism 5 for moving the claws 111 and 112 into and away from each other is provided in the leg side plate.

  If the back plate mounting drive mechanism 5 is installed in the leg side plate 11 according to the above, the screw member 52 and the like will not be exposed, so that the back of the leg 1 and the like can be easily attached and detached without losing the appearance. The plate mounting structure can be effectively realized. And since the components which comprise a drive mechanism are integrated, construction of the furniture with a backplate, etc. becomes possible, without losing these.

  In this case, the leg side plate 11 has a vertical reinforcing portion 110Y including an outer vertical reinforcing member 110a and a second inner vertical reinforcing member 110c that form a hollow portion at least in part, and the back plate is attached to the hollow portion. Since the drive mechanism 5 is arranged and the rearward fixed claw 111 and the rearward movable claw 112 are associated with the back plate mounting drive mechanism 5 so as to move relative to each other within the reinforcing members 110a and 110c. An accurate scaffold and guide portion can be obtained in the back plate mounting drive mechanism 5, and the fixing force can be reliably input through the smooth contact / separation operation of the rearwardly fixed claws 111 and the rearward movable claws 112.

  Specifically, the drive mechanism 5 for attaching the back plate is provided with a screw member 52 extending along the rear surface of the leg side plate 11, and the screw member 52 is engaged with the rearward movable claw 112 which is one back plate engaging portion. Since these are configured to be screw-fed together, the height of the back plates 3 and 3 can be appropriately aligned by the rearward fixing claws 111 when the desk 2 is laterally connected. The screw member 52 can be easily arranged along the rear surface of the leg side plate 11 and can be applied regardless of the distance between the rearward fixed claw 111 and the rearward movable claw 112, so that the design is easy and the original function of screw feeding can be achieved. By using this, a high driving force can be obtained with a light operating force.

  And since the rotational force input end 52x for rotating the screw member 52 is exposed from the leg side plate 11 along the upper direction or diagonally upper direction of the screw member 52, it can be operated from above or diagonally upward. Work can be performed from above with the back plate 3 attached to the rear surface of the leg side plate 11, and good workability can be ensured.

  In this case, the screw member 52 is provided with a rotational force input end 52x on the head 52a, and is configured to screw-feed the rearward movable claw 112 by rotating in a state where a part is pressed against the retainer 53. In addition, a shutter 54 is detachably disposed in the leg side plate 11 adjacent to the head 52a, and an opening window 44a for opening the rotational force input end 52x upward is provided in the shutter 54. . That is, when the screw member 52 is loosened, if the entire screw member 52 is moved upward due to the reaction force, a substantial screw feeding function for the backward movable claw 112 cannot be exhibited. Since the axial center position of the screw member 52 is kept constant, the backward movable claw 112 can be accurately screwed by the rotational force input to the rotational force input end 52x.

  Further, when the backward fixed claw 111 is in a fixed position and engages with the hook hole 301 of the back plate 3, positioning with respect to the back plate 3 is performed, and the backward movable claw 112 engages with the opening 302 of the back plate 3. Since it is configured so that it fits, the upper and lower edges of the back plate 3 will be surely aligned when the desks are connected horizontally, and an easy-to-view layout can be easily realized even with simple connection work. it can.

  Further, the leg side plate 11 constitutes the U-shaped leg 1 in side view together with the stay part 12 and the base part 13, and in particular, the leg mounting drive mechanism is easily exposed to the outside. Therefore, application of the present embodiment greatly improves the conventional problems.

  And if such a backplate attachment structure is utilized, the furniture with a backplate which can perform attachment / detachment of the backplate 3 easily and appropriately, without impairing an external appearance can be provided.

  The specific configuration of each part is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

  For example, when attaching a top plate or a back plate, as shown in FIG. 16, the first and second engaging portions are composed of a pair of movable claws m1 and m2, and one of the movable claws m1 is penetrated. The member m3 is screwed into the other movable claw m2, and a screw feed operation of the screw member m3 relative to the other movable claw m2 is performed, whereby the head m3 ′ of the screw member m3 and the screw hole m2 ′ of the movable claw m2 The distance between the movable claws m1 and m2 may be relatively moved. In this case, when both the movable claws m1 and m2 are inserted into the pair of hook holes m4 and m5 as described above, both the movable claws m1 and m2 move in the axial direction together with the screw member m3 within a range in which the movable claws m1 and m2 can move freely through the hook holes. However, when the distance between the head m3 ′ of the screw member m3 and the screw hole m2 ′ of the movable claw m2 is changed by screw feeding, the movable claws m1 and m2 are at the edges of the hook holes m4 and m5 at a certain distance. It becomes possible to attach a top plate or a back plate to a leg. And according to such a structure to be tightened, the positioning of the top plate and the back plate or the back plate and the leg or the back plate and the leg is made differently without dragging the top plate or the back plate by screw feed. Since it can position by a means, the simplification of the attachment or detachment operation | work of a top plate or a backplate and these higher positioning functions can be made compatible.
