The present disclosure relates to a flap desk with a rotatable desk plate.

In residential environments that require effective use of limited space, it is often difficult to install large desks. On the other hand, from the perspective of work efficiency, there is a high need for desks that can secure sufficient work space. Particularly recently, as telework and online classes have become more common, the demand for desks in households has increased significantly, and it is expected that the demand for such desks will continue to increase in the future. be done.

Under such circumstances, a flap desk equipped with a foldable desk plate is advantageous in making effective use of living space while ensuring a sufficiently large work space.

As an example of a flap desk, Patent Document 1 discloses a writing desk that includes a rotatably provided writing deck (desk board). This writing deck is attached to the shelf board via a hinge, and is also attached to the inner wall surface of the desk housing via a stay, and rotates while being supported by the hinge and the stay (as a result, the shelf board and desk housing).

Japanese Patent Application Publication No. 7-313271

As mentioned above, flap desks are an effective form of both securing work space and space-saving installation, but the work space on the desk is not always fully utilized, and the desk structure (especially The rotating support structure of the desk plate is often complicated.

For example, in the writing desk of Patent Document 1, the writing deck rotates while being supported by a stay attached to the top surface (that is, the work surface) of the writing deck. Therefore, the actual working space is limited by the presence of the stay. Furthermore, stays that are constructed by combining a plurality of movable members are more likely to break down after long-term use.

The present disclosure has been made in view of the above-mentioned circumstances, and aims to provide a technique advantageous for realizing a functional flap desk with a simple configuration.

One aspect of the present disclosure provides a desk plate and a rotating system that supports the desk plate so as to be vertically rotatable near one end edge between a folded rotation position having a predetermined standing angle and an unfolded rotation position having a substantially horizontal angle. The present invention relates to a flap desk comprising a support part and an auxiliary support part that comes into contact with the upper surface of the extra length part located on the opposite side of the rotation tip from the rotation center of the desk plate in the unfolded rotation position.

The flap desk may include a storage section having a storage space, and the auxiliary support section may be attached to the storage section and provided such that the amount of downward protrusion from the storage section can be adjusted.

A flap desk is a storage unit that includes a storage horizontal member extending in the horizontal direction and a storage upright member extending in the height direction, and a storage space partitioned by the storage horizontal member and the storage upright member. The storage upright member may limit rotation of the desk plate toward the folding rotation position.

The desk board may have a top surface exposed upward in the unfolded rotation position, and the rotation support portion may have a torque hinge that contacts a portion of the desk board other than the top surface.

The flap desk has a storage space, a frame part that rotatably supports the desk board via a rotation support part, and a door part that is attached to the frame part so that it can be opened and closed, and is positioned in a folding rotation position. The desk board is placed in the storage space, the door is placed in the closed position with the desk board placed in the storage space to cover the storage space, and the desk board is placed in the open position with the door. It may be positioned in the deployed rotation position without covering the storage space.

According to the present disclosure, a functional flap desk can be realized with a simple configuration.

A flap desk according to an embodiment of the present disclosure will be described with reference to the drawings.

FIG. 1 is a perspective view of an example of a flap desk 10, showing a partially disassembled state. FIG. 2 is an enlarged side view showing a portion of the flap desk 10 shown in FIG. 1 near the desk plate 11 and storage stopper 13. In FIG. 2, illustration of one side panel 23 (that is, the side panel 23 on the near side in the drawing) is omitted, and an example of the state of the storage space T (inner space of the body part 20) is shown. FIG. 3A is a perspective view of the desk board 11 and the storage stopper 13. FIG. 3B is an enlarged view of the desk plate 11 and torque hinge 12 shown in FIG. 3A. 4A and 4B are perspective views of the storage stopper 13 seen from the front side and the back side, respectively. FIG. 5A is a perspective view showing an example of the back structure of the frame portion 20. FIG. 5B is an enlarged view of the top panel 22 and side panel 23 shown in FIG. 5A, with illustration of the back panel 21 omitted and showing a structural example of the inner surface of the side panel 23.

In the following description, width direction H1, depth direction H2, and height direction H3 are orthogonal to each other, width direction H1 and depth direction H2 are directions extending along a horizontal plane, and height direction H3 is a direction extending along a vertical plane. It is the direction.

The flap desk 10 shown in FIGS. 1 to 4B includes a desk plate 11 that is rotatably supported by a body part 20, and a pair of door parts 26 that are attached to the body part 20 via door opening/closing hinges 43 so as to be openable and closable. , is provided.

The body part 20 includes left and right side panels 23 extending in the height direction H3, a top panel 22 and a bottom frame 25 extending in the width direction H1 between the left and right side panels 23, and a height on the back side. A back panel 21 extending in direction H3 is provided. The top panel 22 is attached to the upper ends of the left and right side panels 23 via joint parts 42 such as dowels. The lower frame 25 is attached to the lower ends of the left and right side panels 23 via joining parts 42 such as dowels.

The back panel 21 is mounted on the left and right side panels 21 with its ends (left and right ends and upper end) fitted into the mounting grooves 32 (see FIG. 5B) of the left and right side panels 23 and the top panel 22. 23 and the top panel 22 on three sides. The back panel 21 of this example greatly contributes to improving the overall rigidity of the body part 20 by being fitted into each attachment groove part 32 together with an adhesive (not shown). For example, while the corresponding end of the back panel 21 is fitted into each mounting groove 32, the back panel 21 may be fixed with screws (for example, wood screws) until the adhesive applied to each mounting groove 32 dries. It may be temporarily fixed to the lower frame 25 using a fixture. In this example, as shown in FIG. 5A, on the back surface of the back panel 21, a plurality (six) of back crosspieces 28 extending in the width direction H1 and a plurality of (two) back surfaces extending in the height direction H3 are provided. Crosspieces 28 are attached, and the back panel 21 is supported by these rear crosspieces 28. A fixture 30 for temporarily fixing the back panel 21 to the lower frame 25 is provided so as to completely penetrate the rear crosspiece 28 and the back panel 21 and at least partially through the lower frame 25.

As shown in FIG. 1 and the like, the left and right side panels 23 and the top panel 22 also extend in the depth direction H2. The body part 20 has a storage space T surrounded by left and right side panels 23, a top panel 22, and a back panel 21. The user attaches one or more movable shelves 44 extending in the width direction H1 in the storage space T to an attachable area of the left and right side panels 23 (especially at a height position according to preference), It can be removed from the left and right side panels 23.

The desk board 11 is attached to the body part 20 (particularly the left and right side panels 23) via a pair of torque hinges 12 (rotation support parts), and is rotated between the unfolded rotation position P1 and the folded rotation position P2. Rotatably provided. The desk plate 11 positioned at the unfolded rotational position P1 forms a substantially horizontal angle. The desk board 11 positioned at the folding rotation position P2 forms a predetermined standing angle with respect to the horizontal plane.

In this example, the desk board 11 is positioned at the unfolded rotational position P1, so that the desk top surface 11s of the desk board 11 is oriented upward and spread out generally horizontally, thereby forming a work surface. On the other hand, by positioning the desk board 11 at the folding rotation position P2, the entire desk board 11 is placed (accommodated) in the inner space (storage space T) of the frame section 20, and the desk top surface 11s and desk back surface 11r are Each is arranged so as to extend approximately vertically.

Each torque hinge 12 supports the desk plate 11 so as to be rotatable between the unfolded rotation position P1 and the folded rotation position P2, and supports the desk plate 11 at any position between the unfolded rotation position P1 and the folded rotation position P2. It is also possible to support it so that it is stopped at the rotational position. In this way, the torque hinge 12 supports the desk plate 11 in the vicinity of its one end so that it can rotate vertically, and since the desk plate 11 rotates while being supported by the torque hinge 12, the speed of the desk plate 11 during rotation and The momentum is suppressed by the torque hinge 12. Thereby, the desk board 11 can be rotated and placed quietly in each of the unfolded rotation position P1 and the folded rotation position P2, and the desk board 11 is supported in the unfolded rotation position P1 and the folded rotation position P2. This prevents the desk board 11 from colliding forcefully against a stopper (adjuster 15 and storage upright member 13b, which will be described later).

The torque hinge 12 of this embodiment is fixed in contact with a portion of the desk board 11 other than the desk top surface 11s. The illustrated torque hinge 12 is a uniaxial free stop type torque hinge, which is attached to the back surface 11r of the desk via a top plate fixing screw 12c, and is attached to the side via a torque hinge washer 12a and a washer fixing screw 12b. It is attached to the panel 23.

In this embodiment, each torque hinge 12 is used as a rotation axis (fulcrum) of the desk plate 11, and the desk plate 11 is connected to a horizontal axis (rotation axis Ax (see FIG. 3A) passing through the rotation fulcrum Rp of the torque hinge 12. and FIG. 3B)). Of the desk board 11, the desk front side portion 11A located on the front side of the rotation fulcrum Rp and the desk back side portion 11B located on the back side of the rotation fulcrum Rp have rotational behavior opposite to each other. show. That is, when the desk plate 11 rotates in the folding direction D1 from the unfolded rotation position P1 to the folded rotation position P2, the front side portion 11A of the desk rises while drawing an arcuate trajectory, but the back side portion 11B of the desk moves up in an arcuate trajectory. It descends while tracing a trajectory. On the other hand, when the desk plate 11 rotates in the unfolding direction D2 from the folding rotation position P2 to the unfolding rotation position P1, the desk front part 11A descends in an arcuate trajectory, but the desk back part 11B moves in an arcuate direction. It rises in a trajectory.

The flap desk 10 of this embodiment further includes a storage stopper 13 attached to the frame 20. The storage stopper 13 functions as a storage section having a storage space S, and also functions as a stopper (folding stopper) that limits rotation of the desk board 11 at the folding rotation position P2.

The storage stopper 13 of this example includes a storage horizontal member 13a extending in the width direction H1 and a storage upright member 13b extending in the height direction H3. As shown in FIG. 5A, the storage horizontal member 13a is fixedly attached to the back panel 21 and the back crosspiece 28 using fixing tools 30 such as screws. Further, the storage upright member 13b is attached to the left and right side panels 23 via joint parts 42 such as dowels, as shown in FIG. The storage horizontal member 13a and the storage upright member 13b attached to the frame portion 20 in this manner are arranged so as to have a T-shaped cross section as a whole. Thereby, the storage space S that opens upward is divided by the storage stopper 13, the left and right side panels 23, and the back panel 21.

The storage space S is provided as a part of the storage space T, and some of the stored items C stored in the storage space S are stored in other spaces of the storage space T (particularly the space above the storage space S). may be placed. Since the stored items C stored in the storage space S are placed on the storage horizontal member 13a, the storage horizontal member 13a receives a load from the stored items C in the vertical direction (downward). Since the storage horizontal member 13a of this example is supported by the back panel 21 and the rear crosspiece 28 via the fixture 30 as described above, even if it receives a relatively large load from the stored item C, It can be stably supported. Any storage item C can be stored in the storage space S. For example, even if a laptop computer, a tablet terminal, a power strip, an AC adapter, a power cable, stationery, etc. are placed in the storage space S as a storage item C. good.

In this example, as shown in FIGS. 4A and 4B, a wiring hole 45 configured as a through hole connected to the storage space S is provided in the storage horizontal member 13a. On the other hand, as shown in FIG. 3A, a through hole 46 formed by a notch is provided in the desk plate 11 (particularly at the back edge portion of the desk back section 11B). These wiring holes 45 and through holes 46 face each other and communicate with the storage space S when the desk plate 11 is placed at the unfolded rotation position P1. By arranging cords such as power cords so as to pass through the wiring hole 45 and the through hole 46, one end of the cords can be positioned in the storage space S, while the other end can be positioned outside the storage stopper 13. is possible.

As shown in FIGS. 4A and 4B, the wiring hole cover 41 is provided so as to be slidable on the upper surface of the storage horizontal member 13a. The wiring hole cover 41 is slid by the user's hand and can be placed in a covering position that covers the entire wiring hole 45 and a non-covering position that does not cover at least a portion of the wiring hole 45.

Two (plural) adjusters 15 (deployment stoppers) for positioning the desk board 11 at the deployment rotational position P1 are attached to the storage horizontal member 13a at positions spaced apart in the width direction H1 (see FIG. 2). Each adjuster 15 contacts from above a portion of the desk plate 11 that rotates upward when the desk plate 11 rotates toward the unfolded rotation position P1 (i.e., the back side portion 11B of the desk). The rotation of the entire plate 11 is restricted and the desk plate 11 is positioned at the unfolded rotation position P1. In this way, the back part 11B of the desk is farther from the rotational tip (the tip of the front part 11A of the desk) than the center of rotation of the desk plate 11 (see rotation axis Ax in FIGS. 3A and 3B), which takes the unfolded rotational position P1. It forms the extra length located on the opposite side. Each adjuster 15 acts as an auxiliary support part that comes into contact with the upper surface of the extra length part (desk rear part 11B) when the desk board 11 is located at the unfolded rotational position P1.

In particular, each adjuster 15 in this example is provided so that the amount of downward protrusion from the storage horizontal member 13a can be finely adjusted manually. That is, each adjuster 15 is attached to the storage horizontal member 13a by screwing into an engagement hole (not shown) of the storage horizontal member 13a. The amount of protrusion of each adjuster 15 from the storage horizontal member 13a changes depending on the amount of rotation of each adjuster 15 with respect to the storage horizontal member 13a.

For example, by turning each adjuster 15 clockwise, the amount of protrusion of each adjuster 15 is increased, and as a result, the back side portion 11B of the desk plate 11 located at the deployed rotation position P1 is lowered, and the front side portion 11A of the desk plate 11 is lowered. can be raised. On the other hand, by turning each adjuster 15 counterclockwise, the amount of protrusion of each adjuster 15 is reduced, and as a result, the back side portion 11B of the desk plate 11 located at the deployed rotation position P1 is raised, and the front side of the desk is raised. Portion 11A can be lowered.

By adjusting the amount of rotation of each adjuster 15 with respect to the storage horizontal member 13a in this way, the attitude of the desk board 11 located at the unfolded rotational position P1 can be adjusted.

Each adjuster 15 in this example is constituted by a so-called knurled screw. That is, the portion of each adjuster 15 that projects downward from the storage horizontal member 13a includes a knurled portion. When this knurled portion is held and rotated by hand, the entire adjuster 15 is rotated.

Further, each adjuster 15 in this example includes a metal part that can be engaged with a tool (eg, a screwdriver or a hex wrench). That is, the portion of each adjuster 15 that is exposed upward when attached to the storage horizontal member 13a includes such a metal fitting portion. By rotating the metal part using a tool, the entire adjuster 15 is rotated.

In this way, the amount of protrusion of the adjuster 15 can be adjusted from both above and below, which is convenient. For example, with the desk plate 11 placed at the unfolded rotation position P1, the user can adjust the unfolded rotation position P1 of the desk plate 11 by rotating each adjuster 15 using a tool. Further, with the desk plate 11 placed at the unfolded rotation position P1, the user can adjust the unfolded rotation position P1 of the desk plate 11 by rotating each adjuster 15 while holding the knurling part with his/her hand. can.

The storage upright member 13b restricts the rotation of the desk board 11 in the folding direction D1, and positions the desk board 11 at the folding rotation position P2. This can prevent the desk board 11 moving toward the folding rotation position P2 from colliding with the stored items C accommodated in the storage space S. In particular, from the viewpoint of preventing a collision between the stored items C and the desk board 11 by preventing the desk board 11 from entering the space above the storage space S (storage space T), the arrangement is made at the folding rotation position P2. The storage upright member 13b contacts the desk board 11 placed at the folding rotation position P2 to limit rotation of the desk board 11 so that the entire desk board 11 extends parallel to the height direction H3. It is preferable to do so.

A cushioning material 14 such as felt having excellent shock absorption properties is attached to the lower surface of the storage upright member 13b. Since the storage stopper 13 of this example has a T-shaped cross section, the lower surface of the storage upright member 13b and the cushion material 14 are located below the storage horizontal member 13a. Therefore, the cushion material 14 also functions as a stopper that limits the rotation of the desk board 11 in the deployment direction D2, and prevents the desk board 11 from rotating excessively in the deployment direction D2. In other words, when the amount of protrusion of each adjuster 15 is very small, the back part 11B of the desk comes into contact with the cushioning material 14 without contacting each adjuster 15, and the rotation of the desk plate 11 in the deployment direction D2 is stopped. be done.

FIG. 6 is a perspective view showing an example of the flap desk 10, showing a state in which the desk plate 11 is placed at the unfolded rotation position P1 and the pair of door sections 26 are placed at the open position P11. FIG. 7 is a perspective view showing an example of the flap desk 10, showing a state in which the desk plate 11 is placed at the folding rotation position P2 and the pair of door sections 26 are placed at the open position P11. FIG. 8 is a front view showing an example of the flap desk 10, showing a state in which the desk plate 11 is placed at the folding rotation position P2 and the pair of door sections 26 are placed at the closed position P12.

As shown in FIG. 6, the desk board 11 is positioned at the unfolded rotational position P1 with the door 26 located at the open position P11 and not covering the storage space T. This allows the user to work using the desk board 11 while sitting on the chair 70 or while standing.

On the other hand, as shown in FIG. 8, the door part 26 covers the desk board 11 and the storage space T by being placed in the closed position P12 with the desk board 11 being placed in the storage space T. The user rotates the desk plate 11 to place it in the folding rotation position P2 with the door 26 placed in the open position P11 as shown in FIG. 7, and then opens the door 26 as shown in FIG. 26 can be placed in the closed position P12. In the example shown in FIG. 8, the desk board 11 is visible from the outside of the flap desk 10 through the notch of each door 26 when the pair of doors 26 are placed in the closed position P12.

Note that the chair 70 in a folded state may be accommodated in a space below the desk board 11 in the storage space T, which is the inner space of the body part 20 (see FIGS. 6 and 7). In this case, there is no need to secure storage space for the chair 70 outside the flap desk 10, and the user can handle the flap desk 10 and the chair 70 as one unit. In particular, in this example, since the occupied range of the lower frame 25 in the depth direction H2 is small, a relatively large space (storage space T) can be secured in front of the lower frame 25, and this space is suitable as a storage space for the chair 70. It can be used for

As described above, according to the present embodiment, each adjuster 15 comes into contact from above with the desk back portion 11B that moves upward when the desk plate 11 rotates toward the deployed rotation position P1. , the desk plate 11 is positioned at the unfolded rotation position P1. Thereby, each adjuster 15 limits the angular range of the desk plate 11 with respect to the unfolding direction D2 of the desk plate 11, and prevents the desk plate 11 from rotating excessively. Furthermore, when each adjuster 15 receives a downward load on the front side portion 11A of the desk while positioning the desk board 11 at the unfolded rotational position P1, it bears such load via the back side portion 11B of the desk. Therefore, each adjuster 15 exhibits a function of preventing excessive rotation of the desk plate 11 disposed at the deployed rotation position P1, and also exhibits a load bearing function. As described above, according to this embodiment, the foldable and functional flap desk 10 can be realized with a simple configuration, and parts such as a down stay and a drop hinge are not required.

As a result, it is possible to provide a flap desk 10 that has excellent durability (including load resistance, strength stability, and failure resistance) while suppressing an increase in the number of parts, and reduces parts cost, ease of assembly, and appearance ( It is also advantageous in terms of design) and securing of work space.

In particular, in this embodiment, the torque hinge 12 for supporting the desk board 11 is attached to a location on the desk board 11 other than the desk top surface 11s (specifically, the desk back surface 11r). Therefore, the effective range of the desk top surface 11s that can be substantially used by the user and the space (work space) above the effective range are not narrowed by the torque hinge 12.

Further, the user can use the adjuster 15 to adjust the unfolded rotational position P1 of the desk board 11. As a result, even if the unfolding rotational position P1 of the desk plate 11 changes from its original position due to changes in the flap desk 10 over time, the user can use the adjuster 15 to adjust the unfolding rotational position P1 of the desk plate 11 to an appropriate position. .

Further, according to the present embodiment, the space occupied by the flap desk 10 (especially the occupied range in the depth direction H2) can be suppressed by disposing the desk board 11 at the folding rotation position P2 and closing the door part 26. . As a result, for example, it is possible to effectively utilize the space along the wall of the room as the installation space for the flap desk 10, and it is possible to install the flap desk 10 in a form that harmonizes with the room so as not to spoil the aesthetics of the room. It is. In particular, since the door section 26 can be closed with the stored items C stored in the storage space S and the storage space T inside the body part 20 (see FIG. 8), the flap desk 10 of this embodiment can accommodate the stored items C. It can also be used as furniture for storing.

In this way, the flap desk 10 of this embodiment is effective in ensuring both work space and space-saving installation.

In the embodiment described above, the torque hinge 12 (rotation support part) is attached to the desk back surface 11r of the desk board 11, but the location on the desk board 11 where the torque hinge 12 is attached is not limited. For example, the torque hinge 12 may be attached to the side surface of the desk board 11 (the surface extending between the desk top surface 11s and the desk back surface 11r).

Further, in the above-described embodiment, the storage stopper 13 has a T-shaped cross section, but the installation form of the storage stopper 13 is not limited. The storage horizontal member 13a and the storage upright member 13b may be arranged, for example, so as to have an L-shaped cross section as a whole.

Further, as shown in FIG. 6, a lead-in hole 47 penetrating each side panel 23 and a lead-in cover 48 that is at least partially inserted into the lead-in hole 47 may be provided. The lead-in hole 47 can be used, for example, as a hole for passing a power cord. The retraction cover 48 is variably opened to accommodate a cord or the like passing through the retraction hole 47. By disposing the power cord so as to pass through the lead-in hole 47 and the lead-in cover 48, it is possible to arrange the power tap inside the body part 20 regardless of whether the door part 26 is opened or closed.

For example, the power cord can be arranged to reach the storage space S from the lead-in hole 47 and the lead-in cover 48 through the through-hole 46 (see FIG. 3A) and the wiring hole 45 (see FIGS. 4A and 4B). It is. In this case, the power tap can be placed in the storage space S, and can be used as a power source for the stored items C stored in the storage space S.
