Description

The present invention relates to a desk.

Conventionally, desks with a top supported by left and right legs have been known (see, for example, Patent Document 1). The left and right legs of this desk have relatively heavy, large leg side panels, with stays and bases extending forward from above and below the leg side panels, and the rear ends of the leg side panels are connected by a top panel.

However, when the left and right legs include front and rear legs that extend vertically, in order to ensure a certain level of strength to support the tabletop, a cross member is used to connect not only the left and right rear legs but also the left and right front legs.

However, with this type of configuration, the cross member is located on the underside of the tabletop between the left and right front legs, which not only narrows the space under the tabletop for the user's lower legs, but also makes it difficult to attach options such as drawers that would be convenient for the user.

The vertical width of the connecting frame 23 is set to be longer than the horizontal width. The upper surface of the connecting frame 23 is designed to be attached to the lower surface of the tabletop 1.

The outer surface of the front end of the connecting frame 23 is rigidly connected to the inner surface of the upper end of the front leg 21. The outer surface of the rear end of the connecting frame 23 is rigidly connected to the inner surface of the upper end of the rear leg 22. Two screw insertion holes h1 that penetrate in the vertical direction are provided at the front and rear of the connecting frame 23. The leg body 2 is attached to the tabletop 1 by screwing a screw v1 inserted into the screw insertion hole h1 of the connecting frame 23 into a nut portion n1 provided on the tabletop 1.

A cantilever frame 24 is connected to the front end of the connecting frame 23 so that the internal space of the connecting frame 23 cannot be seen. The fascia board main body 31 of the connecting frame 3 is arranged on the back side of the rear end of the connecting frame 23 with a gap between them.

The cantilever frame 24 is mainly composed of a metal square pipe material that extends linearly in the left-right direction. The cantilever frame 24 protrudes inward from the front end of the connecting frame 23, i.e., toward the middle part of the desk in the left-right direction. The top surface of the cantilever frame 24 is designed to be attached to the bottom surface of the tabletop 1. The base end, i.e., the outer end, of the cantilever frame 24 is rigidly connected to the front end of the connecting frame 23.

The cantilever frame 24 is attached to the underside of the tabletop 1 at approximately the center in the front-to-rear direction. Therefore, the cantilever frame 24 provides a balanced anti-warping function for the entire tabletop 1.

A cap Q is attached to the tip of the cantilever frame 24. The base end of the cap Q is fitted into the opening of the cantilever frame 24, and the tip has an inclined surface q1 that faces diagonally downward.

The cantilever frame 24 has two screw insertion holes h2 that penetrate in the vertical direction at the left and right sides. The leg 2 is attached to the tabletop 1 by screwing a screw v2 inserted into the screw insertion hole h2 of the cantilever frame 24 into a nut portion n2 provided on the tabletop 1. As shown in FIG. 12, the base end of the cap Q also has a screw insertion hole h2a that penetrates in the vertical direction and through which the screw v2 is inserted.

In this embodiment, the longitudinal dimension w2 of the cantilever frame 24 is set to be shorter than the longitudinal dimension w3 of the connecting frame 23. More specifically, the left-right dimension w2 of the cantilever frame 24 is set to be less than half the front-rear dimension w3 of the connecting frame 23 (more specifically, about one-third the length of the front-rear dimension of the connecting frame 23).

The connecting member 3 connects the rear parts of the left and right legs 2. The connecting member 3 is formed by bending a metal plate. The connecting member 3 includes a fascia 3A arranged on the opposite end edge 1e of the tabletop 1.

The connecting member 3 comprises a fascia 3A, a wiring guide groove forming section 3B that extends forward from the upper end of the fascia 3A and can form a wiring guide groove C, and a shelf 3C that extends forward from the lower end of the fascia 3A and has an upper surface that serves as a placement surface 35s on which items such as wiring (not shown) can be placed.

The skirting board 3A is made up of a skirting board main body 31 that is an upright board and has a generally rectangular shape when viewed from the rear, and a connecting plate 32 that extends forward from both side ends of the skirting board main body 31 and is generally perpendicular to the skirting board main body 31 and connects to the rear leg 22.

The skirting board body 31 is disposed so as to fill the gap between the upper portions of the left and right rear legs 22. A notch i is formed at the upper left and right corners of the skirting board body 31, allowing the cover body D to be positioned. The connecting plate 32 is provided with screw insertion holes h3 at two locations, top and bottom. The left and right legs 2 and the connecting member 3 are connected by screwing a screw v3 inserted through the screw insertion hole h3 in the connecting plate 32 into a nut portion n3 in the rear leg 22.

The wiring guide groove forming portion 3B includes a rear groove wall 33 extending downward and forward from the upper end of the fascia board main body 31, and a bottom groove wall 34 extending approximately horizontally forward from the lower end of the rear groove wall 33.

The rear groove wall 33 is tilted backward. In other words, the forward surface 33s of the rear groove wall 33 is tilted so that it is gradually positioned upward toward the rear.

The bottom groove wall 34 has three notches 34a formed in the left-right center and both left and right ends to allow wiring to pass vertically. The front end of the bottom groove wall 34 has multiple screw insertion holes h4 that penetrate vertically. The connecting member 3 and the top plate 1 are connected by screwing a screw v4 inserted through the screw insertion hole h4 of the bottom groove wall 34 into a nut portion n4 provided at the rear end of the top plate 1.

Shelf board 3C comprises a shelf board body 35 having a mounting surface 35s facing upward, and a standing wall 36 erected at the front end of shelf board body 35 to prevent items from falling. Shelf board 3C is designed so that some of the wiring, which is the main item, can be placed on mounting surface 35s.

The wiring guide groove C is provided along the upper end of the fascia 3A and opens upward. The wiring guide groove C is always open upward except for the portion where the movable member B is arranged. The wiring guide groove C is composed of the anti-use edge 1e of the top plate 1, which is a front groove wall having a rearward surface and extending in the left-right direction, the rear groove wall 33 of the connecting frame 3, which is arranged rearward of the anti-use edge 1e of the top plate 1 and has a forward surface 33s and extends in the left-right direction, and the bottom groove wall 34 of the connecting frame 3, which has an upward surface 34s and is arranged between the lower end of the anti-use edge 1e of the top plate 1 and the rear groove wall 33. Both left and right ends of the wiring guide groove C are closed by cover bodies D, respectively.

As shown in FIG. 3, for example, a movable member B is disposed in the wiring guide groove C so as to be movable in the left-right direction, i.e., along the longitudinal direction of the wiring guide groove C. In order to allow the movable member B to be disposed in the wiring guide groove C without rattling, the separation dimension w1 between the rear surface of the top plate 1 and the front surface 33s of the rear groove wall 33, which constitute the wiring guide groove C, is configured to gradually increase upward.

The cover body D is box-shaped and open downward. The cover body D covers the upper end of the rear leg 22 and can cover both sides of the wiring guide groove C.

The cover body D includes a top wall d1, a front wall d2 extending downward from the front end of the top wall d1, a rear wall d3 extending downward from the rear end of the top wall d1, an outer wall d4 connecting the outer ends of the front wall d2 and the rear wall d3, and an inner wall d5 connecting the inner ends of the front wall d2 and the rear wall d3.

The lower end of the front wall d2 is provided with an engagement portion k1 that protrudes forward and can engage with the underside of the side end at the rear end of the top plate 1, as shown particularly in Figures 14 to 16.

As shown in FIG. 15, the lower end of the rear wall d3 is provided with two positioning protrusions d31 that protrude downward and can engage with the inner surface of the upper end of the rear leg 22, and a positioning protrusion d32 that protrudes downward and can engage with the inner surface of the rear end of the connecting frame 23.

As shown in Figures 10 and 15, the rear of the inner wall d5 is provided with a convex portion k2 that protrudes inward, i.e., toward the center of the desk in the left-right direction, and is inserted into an insertion hole G formed by the outer edge of the upper end of the back panel main body 31 and the outer edge of the rear groove wall 33. The lower edge of the inner wall d5 is provided with a convex edge d51 that protrudes downward and can engage with the inner edge of the upper end of the connecting frame 23.

The cover body D is positioned on the rear legs 22 and the connecting frame 23 by engaging the engagement portion k1 with the top plate 1, the positioning protrusions d31 and d32 engaging with the rear legs 22 and the connecting frame 23, the convex edge d51 engaging with the connecting frame 23, and the convex portion k2 being inserted into the insertion hole G. An inclined surface d5s is formed on the inner wall d5 of the cover body D, which is inclined so as to be positioned gradually upward toward the outside. The inclined surface d5s functions as a blocking surface that blocks both longitudinal ends of the wiring guide groove C, improving the design of both ends of the wiring guide groove C.

The movable member B is made of synthetic resin. In this embodiment, multiple movable members B, i.e., two movable members B, are shown arranged in the wiring guide groove C, but the number of movable members B may be one or more than two.

The movable member B has an upward surface b1s that is substantially flush with the upper surface 1s of the top plate 1, a recessed portion b3 that is provided adjacent to the upward surface b1s and is recessed downward, and a functional portion J that can support an article, such as a smartphone P, in an upright position using the recessed portion b3, and a tunnel forming portion b23 that is provided below the upward surface b1s, has an upward recessed shape, and cooperates with the bottom groove wall 34 of the wiring guide groove C to form a tunnel T.

The movable member B is mainly composed of an upper wall b1 having an upward surface b1s, left and right hanging walls b2 hanging down from both the left and right ends of the upper wall b1, a recessed portion b3 made of an upward U-shaped wall provided at the front end of the upper wall b1, and a front wall b4 arranged in front of the recessed portion b3, and is reinforced by multiple ribs rb.

The upper wall b1 has an upward surface b1s and is rectangular in plan view. A number of ribs rb extending in the left-right and front-rear directions are provided on the bottom side of the upper wall b1.

The left and right hanging walls b2 have their lower edges b21 that can contact the bottom groove wall 34 of the wiring guide groove C. The left and right hanging walls b2 are inclined so that their rear edges b22 are positioned gradually forward as they extend downward. The rear edges b22 of the left and right hanging walls b2 are adapted to engage with the forward facing surface 33s of the rear groove wall 33 that constitutes the wiring guide groove C. In other words, the movable member B has the rear edges b22 of the left and right hanging walls b2, which are rear engagement portions that can engage with the rear groove wall 33.

A tunnel forming portion b23 having an upwardly concave shape is provided in the middle of the left and right hanging walls b2 in the front-to-rear direction. The tunnel forming portion b23 cooperates with the bottom groove wall 34 of the wiring guide groove C to form a tunnel T that can connect the wiring placed on the bottom groove wall 34 in the left-right direction.

The functional part J is provided in front of the upward surface b1s and has a recessed portion b3 that is recessed downward and extends in the left-right direction. The functional part J is capable of supporting various objects (mainly roughly plate-shaped objects) in an upright position by utilizing the recessed portion b3. For example, as shown in FIG. 17, by engaging the lower end of a smartphone P with the recessed portion b3 of the functional part J, the smartphone P can be supported in an upright position that provides excellent viewability for the user.

The front wall b4 is located at the front end and stands up in a substantially vertical direction. The front surface b4s of the front wall b4 is adapted to engage with the opposite usable edge 1e of the top plate 1, which is the front groove wall. In other words, the movable member B has the front surface b4s of the front wall b4, which is the front engagement portion, that can engage with the opposite usable edge 1e of the top plate 1, which is the front groove wall.

The movable member B is capable of forming an expandable placement surface on which an item can be placed. That is, the upper surface 1s of the tabletop 1 and the upward surface b1s of the movable member B cooperate to form a placement surface on which an item can be placed. In other words, the movable member B is capable of expanding the area on which an item can be placed beyond the opposite usable edge e1 of the tabletop 1.

For example, the one shown in FIG. 18 is capable of positioning an item, such as a personal computer display M, behind the rear edge of the tabletop 1 by cooperating with two movable members B arranged in the wiring guide groove C and the rear part of the tabletop 1 adjacent to these two movable members B.

As explained above, the desk according to this embodiment comprises a tabletop 1, left and right legs 2 that are provided in pairs on the left and right and can support the tabletop 1, and a connecting member 3 that connects the rear portions of the left and right legs 2. The left and right legs 2 each comprise front legs 21 and rear legs 22 that extend vertically, a connecting frame 23 that connects the upper ends of the front legs 21 and rear legs 22 and connects to the underside of the tabletop 1, and a cantilever frame 24 that protrudes inward from the front of the connecting frame 23 in a cantilever shape and connects to the underside of the tabletop 1.

This makes it possible to provide a desk that can optimally secure space under the top plate 1 between the front legs 21 that extend in the vertical direction.

In other words, the tabletop 1 is supported by the cantilever frame 24 that protrudes from the front of the connecting frame 23 in a cantilever shape, ensuring optimal space for the user's lower legs. Moreover, with this configuration, it is easy to attach options such as drawers to the underside of the tabletop 1 without being hindered by reinforcing beams or cross members.

The connecting member 3 is formed by bending a metal plate, and includes a fascia 3A arranged on the opposite end edge 1e of the tabletop 1.

As a result, the left and right legs 2 are optimally supported by the connecting member 3, which includes the fascia 3A.

The fascia 3A comprises an upright fascia body 31 and connecting plates 32 that extend forward from both ends of the fascia body 31 and connect to the rear legs 22.

For this reason, the apron 3A can be conveniently attached to the left and right rear legs 22.

A wiring guide groove C that opens upward is provided on the opposite end edge 1e of the top plate 1. The connecting frame 3 includes a fascia 3A, a wiring guide groove forming portion 3B that extends from the upper end of the fascia 3A and can form the wiring guide groove C, and a shelf 3C that extends forward from the lower end of the fascia 3A and can place items on its upper surface.

The connecting frame 3 has excellent strength for connecting the left and right legs 2 because the fascia 3A, wiring guide groove forming portion 3B, and shelf 3C are integrally constructed from metal plate material.

The tabletop 1 has a rectangular shape extending in the left-right direction when viewed from above. This allows for excellent design freedom, as the cantilever frame 24 is designed to not interfere with the space for the lower legs under the tabletop 1.

A plurality of screw insertion holes h1, h2 penetrating in the vertical direction are provided in the connecting frame 23 and the cantilever frame 24. The top plate 1 is attached to the leg bodies 2 by screwing the screws v1, v2 inserted into the screw insertion holes h1, h2 into nuts n1, n2 provided on the top plate 1. Therefore, by screwing the connecting frame 23 and the cantilever frame 24 to the top plate 1, the left and right leg bodies 2 can favorably support the top plate 1.

A cap Q is attached to the inner end of the cantilever frame 24. This allows the cantilever frame 24 to have a good appearance.

The longitudinal dimension of the cantilever frame 24 is set shorter than the longitudinal dimension of the connecting frame 23. As a result, the cantilever frame 24 is relatively short, allowing for adequate space for the user's lower legs.

The present invention is not limited to the embodiments described above.

The cantilever frame need only protrude from the front of the connecting frame, and does not necessarily have to protrude from the front end.

The connecting members are not limited to those formed by bending metal plates.

The left and right legs need only extend vertically, and their specific configurations can vary.

The specific configuration of each part is not limited to the above embodiment, and various modifications are possible without departing from the spirit of the present invention.
