Description

[Technical Field]

[0001] The present invention relates to a fixture with a tabletop for use in work spaces such as offices, public facilities, and schools. [Background technology]

[0002] Conventionally, in work spaces such as offices, public facilities, and schools, furniture with tabletops that users can use as a work surface (the upper surface of the tabletop) has been installed. A known type of furniture with tabletops is one that includes a plurality of legs spaced apart and a tabletop supported by the legs.

[0003] The tabletop-equipped furniture unit shown in Patent Document 1 has a configuration in which an auxiliary tabletop can be attached and detached to the front edge of the tabletop. Specifically, the rear edge of an auxiliary tabletop such as an armrest, keyboard stand, mouse stand, or coffee tray is butted against a predetermined point on the front edge of the tabletop, a bracket is placed across the underside of the tabletop, and the auxiliary tabletop is fixed to the tabletop by tightening a bolt. This allows the desired auxiliary tabletop to be connected flush with the tabletop as needed to expand the work surface of the tabletop, and when no longer needed, the auxiliary tabletop can be easily removed from the tabletop to restore the original work surface.

[0004] [Patent Document 1] Patent No. 3042665 (page 2, Figure 1) Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the fixture with a tabletop in Patent Document 1, the rear edge of the auxiliary tabletop is cantilevered onto the front edge of the tabletop, which makes it difficult to adjust the angle of the auxiliary tabletop so that it is flush with the tabletop due to weight balance issues, and there was a risk that the work of attaching the auxiliary tabletop so that it is flush with the tabletop would become complicated.

[0006] The present invention has been made in response to such problems, and aims to provide a fixture with a tabletop that allows the auxiliary tabletop to be easily held flush with the tabletop. [Means for solving the problem]

[0007] In order to solve the above problems, the fixture with a tabletop of the present invention is A tabletop fixture having a support member installed on a floor surface and a flat tabletop supported by the support member, a notch formed in the top plate from the peripheral edge toward the inside of the top plate; an auxiliary top plate having a functional portion and fitted into the notch portion; a holding means for holding the auxiliary top plate flush with the top plate; By changing the manner in which the auxiliary top plate is attached to the notch portion, the arrangement of the functional part in the tabletop-equipped furniture can be changed. 、 The cutout portion is formed to be wider on the inner side than the opening that opens on the periphery of the top plate. It is characterized by the following. According to this feature, the auxiliary top plate is fitted into the cutout portion, so that the holding means can be arranged in a balanced manner around the auxiliary top plate, thereby making it easy to hold the auxiliary top plate flush with the top plate.

[0008] The holding means is characterized in that it is provided so as to protrude inward from below the top plate. According to this feature, the auxiliary top plate can be easily held flush with the top plate simply by placing the auxiliary top plate on the holding means.

[0009] The cutout portion is characterized in that the depth side of the cutout portion is wider than the opening that opens at the periphery of the top plate. According to this feature, the auxiliary top plate is restricted from sliding from the opening to the outside of the cutout portion, so that the auxiliary top plate can be maintained in a position in the cutout portion.

[0010] The cutout portion is symmetrical in shape, and the front and back surfaces of the auxiliary top plate are functional surfaces having different functional portions. According to this feature, by reversing the front and back sides of the auxiliary top plate, it is possible to use functional surfaces that perform different functions.

[0011] The functional part is characterized by being a cutout recess formed at a position close to one side of the auxiliary top plate in the left-right direction, recessed from the periphery of the auxiliary top plate toward the inside of the auxiliary top plate, for accommodating the operating lever of an electric wheelchair. According to this feature, by reversing the front and back of the auxiliary top plate, the cutout recess that accommodates the operating lever of the electric wheelchair can be positioned to the right or left side.

[0012] The auxiliary top plate is fitted so that the peripheral edge of the auxiliary top plate and the peripheral edge of the top plate are flush with each other. According to this feature, the auxiliary tabletop does not protrude outward beyond the tabletop, so the tabletop-equipped fixture can be made compact and smoothly constructed without steps on the periphery.

DETAILED DESCRIPTION OF THE INVENTION

[0014] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A mode for carrying out a fixture with a top plate according to the present invention will be described below based on an embodiment. [Example]

[0015] The tabletop-equipped fixture according to Example 1 will be described with reference to Figures 1 to 4. In the following description, the top of Figures 3 and 4 will be referred to as the front of the tabletop-equipped fixture, and the left and right sides of the tabletop-equipped fixture when viewed from the back to the front will be referred to as the left and right sides of the tabletop-equipped fixture. Note that the front of the tabletop-equipped fixture may also be referred to as the back side as seen from the user, and the back of the tabletop-equipped fixture may also be referred to as the front side as seen from the user.

[0016] 1 and 2, the tabletop-equipped furniture 1 of this embodiment is a roughly square work table intended for use by users of electric wheelchairs. The tabletop-equipped furniture 1 is mainly composed of a tabletop 2 that is roughly U-shaped in plan view, a tabletop support 3 that serves as a support member for supporting the tabletop 2, an auxiliary tabletop 10 that fits into the cutout portion 2a of the tabletop 2, and a holding means 20 that holds the auxiliary tabletop 10.

[0017] The tabletop support 3 comprises a tabletop support frame 6 consisting of a pair of horizontal rods (support rods) 4, 4 at the front and rear and a pair of vertical rods 5, 5 at the left and right, four leg attachments 7 connected to the front and rear ends of each vertical rod 5, and four leg rods 9 in the shape of square tubes fixed to each leg attachment 7.

[0018] A pair of front and rear horizontal rods 4, 4 extend parallel to each other in the left-right direction. A pair of left and right vertical rods 5, 5 extend parallel to each other in the front-to-rear direction, with both ends of the horizontal rods 4, 4 joined at a position closer to the center than both ends of the vertical rods 5, 5. These horizontal rods 4, 4 and vertical rods 5, 5 are fixed to the underside of the tabletop 2 with bolts (not shown).

[0019] The leg attachment 7 has insertion portions 7a facing in the front-to-rear direction, and is fixed to each vertical rod 5 by fastening with bolts (not shown) with the insertion portions 7a fitted into the front and rear ends of each vertical rod 5. The leg rod 9 is fitted into a square column-shaped insertion portion 7b hanging down from the underside of the leg attachment 7, and is fixed to the leg attachment 7 by fastening with bolts (not shown).

[0020] The tabletop 2 has a cutout 2a on one rear edge of the tabletop 2, recessed from the rear to the front, i.e., toward the inside of the tabletop 2, and penetrating vertically. This cutout 2a has a wide portion 2c at its rear end that is wider in the left-right direction than the opening 2b on the front side. In other words, the cutout 2a has a substantially trapezoidal shape in a plan view. The cutout 2a is formed symmetrically about an imaginary line X (see FIGS. 3 and 4) extending in the front-rear direction at its left-right center (see FIG. 3).

[0021] The outer shape of the auxiliary top plate 10 is substantially the same as the outer shape of the cutout portion 2a in the top plate 2 in a plan view, except for a rear periphery 10d described below. The auxiliary top plate 10 has a cutout recess 10a formed as a functional part at a position closer to the right side in the left-right direction. The cutout recess 10a is recessed from the rear side to the front side and penetrates in the vertical direction.

[0022] The holding means 20 is composed of two receiving members 21, which are metal plates, and a horizontal rod 4 on the front side of the tabletop support 3. One of the receiving members 21 has its left end fixed to a position on the left front side of the cutout 2a in the underside of the tabletop 2, and its right end positioned so as to protrude into the cutout 2a. The other receiving member 21 has its right end fixed to a position on the right front side of the cutout 2a in the underside of the tabletop 2, and its left end positioned so as to protrude into the cutout 2a. In other words, the two receiving members 21 are positioned opposite each other in the left-right direction.

[0023] The front horizontal rod 4 of the tabletop support 3 is disposed in the wide portion 2c of the cutout 2a so that a portion of it is exposed upward from the cutout 2a when the tabletop 2 is attached to the tabletop support 3 (see FIG. 3). It is preferable that a cushioning material such as felt is disposed on the upper surface of the front horizontal rod 4 and the upper surface of the receiving member 21, which makes the auxiliary tabletop 10 less likely to be scratched and less likely to rattle when in use.

[0024] 3, when auxiliary top plate 10 is fitted into cutout portion 2a from above with its surface 10b facing up, auxiliary top plate 10 is placed on left and right receiving members 21 and front horizontal rod 4, and is held so that surface 10b of auxiliary top plate 10 is flush with upper surface 2d of top plate 2. In addition, rear periphery 10d of auxiliary top plate 10 is flush with rear periphery 2e of top plate 2.

[0025] Furthermore, it is preferable that the thickness of auxiliary top plate 10 is the same as the thickness of top plate 2. This allows auxiliary top plate 10 to be held flush with top plate 2 by holding means 20 with a simple structure.

[0026] Furthermore, cutout portion 2a has a wide portion 2c on the rear side that is wider in the left-right direction than opening 2b on the front side, and since the outer shape of auxiliary top plate 10 is the same as the outer shape of cutout portion 2a, when auxiliary top plate 10 is fitted into cutout portion 2a from above, it is prevented from slipping out toward the front side. In other words, horizontal movement of auxiliary top plate 10 is restricted. Furthermore, auxiliary top plate 10 can be removed from cutout portion 2a by lifting it from below.

[0027] Furthermore, the cutout recess 10a of the auxiliary top 10 is located to the right of the imaginary line X. This allows the operating lever L, which is erected on the right side of the electric wheelchair, to be stored in the cutout recess 10a, so the user can approach the top 2 without the operating lever L interfering with the auxiliary top 10. In other words, the surface 10b of the auxiliary top 10 functions as a functional surface with the cutout recess 10a located on the right side.

[0028] As shown in Figure 4, when the auxiliary top 10 is fitted into the cutout 2a from above with its back surface 10c facing up, the cutout recess 10a of the auxiliary top 10 is located to the left of the imaginary line X. This allows the operating lever L installed on the left side of the electric wheelchair to be stored in the cutout recess 10a. In other words, the back surface 10c of the auxiliary top 10 functions as another functional surface with the cutout recess 10a located on the left side.

[0029] In this way, by inverting the front surface 10b and the back surface 10c of the auxiliary top plate 10, the left and right positions of the cutout recess 10a can be changed, so that the operating lever L of the electric wheelchair can be stored in the cutout recess 10a regardless of the installation position of the operating lever L.

[0030] As explained above, the two receiving members 21 and the front horizontal rod 4 can be arranged in a balanced manner around the cutout portion 2a, which allows the auxiliary tabletop 10 to be held flush with the tabletop 2, simplifying the task of holding the auxiliary tabletop 10 flush with the tabletop 2. Furthermore, because the horizontal rod 4 of the tabletop support 3 is used as one of the holding means 20, the tabletop 2 can be held flush with a simple configuration.

[0031] The holding means 20 is provided so as to protrude from below the top plate 2 toward the inside of the top plate 2, i.e., toward the cutout portion 2a. This makes it possible to easily hold the auxiliary top plate 10 flush with the top plate 2 simply by placing the auxiliary top plate 10 on the holding means 20.

[0032] Furthermore, the back side of the cutout portion 2a is a wide portion 2c that is wider in the left-right direction than the opening 2b on the front side. This prevents the auxiliary tabletop 10 from sliding from the opening 2b toward the front side of the cutout portion 2a. In other words, because the horizontal movement of the auxiliary tabletop 10 is restricted, the auxiliary tabletop 10 can be maintained in the cutout portion 2a without the need for fixing work such as screwing.

[0033] Furthermore, the cutout portion 2a is symmetrical, and the front surface 10b and the back surface 10c of the auxiliary top 10 are functional surfaces with different functional portions. Specifically, the cutout recess 10a is located on the right side of the front surface 10b of the auxiliary top 10, and the cutout recess 10a is located on the left side of the back surface 10c of the auxiliary top 10. In other words, the front surface 10b and the back surface 10c of the auxiliary top 10 are functional surfaces with the cutout recess 10a located in different positions on the left and right. This allows the front surface 10b and the back surface 10c of the auxiliary top 10 to be selectively used to perform different functions by flipping the front surface 10b and the back surface 10c of the auxiliary top 10. In this embodiment, the left and right positions of the cutout recess 10a, in which the operating lever L of the electric wheelchair is housed, can be changed.

[0034] Furthermore, auxiliary top plate 10 is fitted so that rear peripheral edge 10d of auxiliary top plate 10 is flush with rear peripheral edge 2e of top plate 2. This means that auxiliary top plate 10 does not protrude forward beyond top plate 2, meaning that there is no step and a smooth gap between peripheral edge 10d and peripheral edge 2e, making top-equipped fixture 1 easy to use and compact.

[0035] In this first embodiment, the left-right position of the cutout recess 10a is changed by inverting the front surface 10b and the back surface 10c of one auxiliary top plate 10, but an auxiliary top plate without a cutout recess may be prepared separately from the auxiliary top plate 10. In this way, when a able-bodied person uses a furniture unit with a top plate, the auxiliary top plate without a cutout recess can be used to make the work surface of the furniture unit with a top plate more widely usable.

[0036] Furthermore, in this embodiment 1, the horizontal rod 4 of the tabletop support 3 is used as one of the holding means 20, but the tabletop may be held by only the receiving member without using the horizontal rod. [Example]

[0037] Next, a fixture with a top plate according to a second embodiment will be described with reference to Fig. 5. Note that a description of the same configuration as in the previous embodiment will be omitted.

[0038] As shown in Fig. 5(a), a recessed groove 210e is provided as a functional part that opens upward at a rear position on the front surface 210b of the auxiliary top plate 210 of this embodiment 2. The recessed groove 210e is designed to allow the tablet terminal D to stand upright. As shown in Fig. 5(b), the rear surface 210c of the auxiliary top plate 210 is formed as a flat surface.

[0039] As shown in Figures 5(a) and (b), by flipping the front surface 210b and the back surface 210c of the auxiliary top plate 210 as needed, the front surface 210b and the back surface 210c can be selectively used to perform different functions. [Example]

[0040] Next, a tabletop-equipped fixture according to a third embodiment will be described with reference to Figures 6 and 7. Note that a description of the same configuration as in the previous embodiment will be omitted.

[0041] 6, the cutout portion 32a of the top panel 32 of the present embodiment 3 has a horizontally elongated hexagonal shape in a plan view. The cutout portion 32a is formed symmetrically with respect to a virtual line X1 extending in the front-rear direction at the center in the left-right direction (see FIG. 7(a)).

[0042] Furthermore, receiving members 321 as holding means extending in the left-right direction in front of and behind the cutout portion 32a are provided on the underside of the top plate 32. The auxiliary top plate 310 is placed on the upper surface of the receiving members 321.

[0043] The auxiliary top plate 310 has an outer shape that is substantially the same as the outer shape of the cutout portion 32a in the top plate 32 in a plan view. A front surface 310b of the auxiliary top plate 310 is provided with a recessed groove 310e that serves as a functional portion opening upward in the shape of a slit, and a recessed portion 310f that serves as a functional portion opening upward in the shape of a cylinder. The recessed groove 310e serves to support, for example, a tablet terminal or the like, and the recessed portion 310f serves, for example, as a drink holder. The rear surface 310c of the auxiliary top plate 310 is formed flat (see FIG. 7(c)).

[0044] As shown in Figure 7(a), in the first insertion pattern of the auxiliary top plate 310, in which the auxiliary top plate 310 is inserted from above into the cutout portion 32a with its surface 310b facing up, the groove 310e is positioned at the back side and the recess 310f is positioned at the right side.

[0045] As shown in Figure 7(b), in the second insertion pattern of the auxiliary top plate 310, which is obtained by rotating the auxiliary top plate 310 horizontally by 180 degrees from the state shown in Figure 7(a), the recessed groove 310e is positioned at the front side, and the recessed portion 310f is positioned at the left side.

[0046] As shown in Figure 7(c), in the third insertion pattern of the auxiliary top plate 310, in which the auxiliary top plate 310 is turned upside down from the state in Figure 7(a), the back surface 310c, which is a flat surface, is positioned upward, so that the groove 310e and the recess 310f are not exposed upward.

[0047] In this way, in the fixture with a tabletop of this embodiment, not only can the auxiliary tabletop 310 be turned upside down and fitted into the cutout portion 32a, but the auxiliary tabletop 310 can also be rotated 180 degrees horizontally to fit into the cutout portion 32a, thereby increasing the freedom to change the arrangement of the functional parts. [Example]

[0048] Next, a fixture with a top plate according to a fourth embodiment will be described with reference to Fig. 8. Note that a description of the same configuration as in the previous embodiment will be omitted.

[0049] 8, the cutout portion 42a of the top plate 42 of this Example 4 is a regular hexagon in plan view. The outer shape of the auxiliary top plate 410 is substantially the same as the outer shape of the cutout portion 42a in the top plate 42 in plan view. A groove 410e is formed on the surface 410b of the auxiliary top plate 410 as a functional portion.

[0050] As shown in FIG. 8(a), in the first fitting pattern of the auxiliary top plate 410, in which the auxiliary top plate 410 is fitted from above into the cutout portion 42a with its surface 410b facing up, the recessed groove 410e is positioned at the rear side.

[0051] As shown in Fig. 8(b), in the second fitting pattern of the auxiliary top plate 410 when the auxiliary top plate 410 is rotated 60 degrees clockwise in the horizontal direction from the state shown in Fig. 8(a), the recessed groove 410e is located at the rear right position. Although not shown, when the auxiliary top plate 410 is rotated 120 degrees clockwise in the horizontal direction from the state shown in Fig. 8(a), the recessed groove 410e is located at the front right position. Furthermore, when the auxiliary top plate 410 is rotated 180 degrees clockwise in the horizontal direction from the state shown in Fig. 8(a), the recessed groove 410e is located at the front position.

[0052] As shown in Fig. 8(c), in the third fitting pattern of the auxiliary top plate 410 when the auxiliary top plate 410 is rotated 60 degrees counterclockwise in the horizontal direction from the state shown in Fig. 8(a), the recessed groove 410e is located at the rear left position. Although not shown, when the auxiliary top plate 410 is rotated 120 degrees counterclockwise in the horizontal direction from the state shown in Fig. 8(a), the recessed groove 410e is located at the front left position. Furthermore, when the auxiliary top plate 410 is rotated 180 degrees counterclockwise in the horizontal direction from the state shown in Fig. 8(a), the recessed groove 410e is located at the front position.

[0053] In this way, by making the outer shape of the cutout portion 42a and the auxiliary top plate 410 a regular hexagon, the position of the recessed groove 410e can be changed every 60 degrees. Note that the cutout portion and the auxiliary top plate are not limited to a regular hexagon, and may be a regular polygon such as a square or a regular pentagon. [Example]

[0054] Next, a tabletop-equipped fixture according to a fifth embodiment will be described with reference to Figures 9 to 11. Note that a description of the same configuration as in the previous embodiment will be omitted.

[0055] As shown in Figures 9(a) and 9(b), the cutout portion 52a of the top plate 52 of this embodiment 5 is rectangular in plan view. That is, the cutout portion 52a has the same width dimension in the front-to-rear direction. Holes 52c, 52c that open to the front and face the front-to-rear direction are formed spaced apart on the left and right sides in the rear end surface 52b of the top plate 52 that constitutes the cutout portion 52a. In addition, dovetail grooves 52e, 52e that open toward the cutout portion 52a are formed in the front-to-rear direction on the opposing inner surfaces 52d, 52d of the top plate 52 that constitute the cutout portion 52a.

[0056] 10(a) and 10(b), the auxiliary top plate 510 of this fifth embodiment is rectangular in plan view, with a front surface 510b formed with the same pattern (for example, wood grain) as the top plate 52, and a back surface 510c formed as a whiteboard different from the top plate 52. Protrusions 510e, 510e that protrude forward are formed spaced apart on the left and right sides on the front end surface 510d of the auxiliary top plate 510. Dovetail-shaped protrusions 510g, 510g are formed on the side surfaces 510f, 510f of the auxiliary top plate 510 in the front-to-rear direction.

[0057] 11(a) and 11(b), the auxiliary top plate 510 is placed in the cutout portion 52a by sliding it from the front side to the back side with the protruding portions 510g, 510g fitted into the dovetail grooves 52e, 52e of the top plate 52. That is, the dovetail grooves 52e, 52e function as a holding means for holding the auxiliary top plate 510. Furthermore, since the dovetail grooves 52e, 52e and the protruding portions 510g, 510g fit together, the auxiliary top plate 510 is effectively prevented from floating upward.

[0058] Furthermore, when the front end surface 510d of the auxiliary top plate 510 abuts against the rear end surface 52b of the top plate 52, the protrusions 510e, 510e are pressed into the holes 52c, 52c, making it difficult for the auxiliary top plate 510 to slide forward from the cutout portion 52a.

[0059] Furthermore, by inverting the front surface 510b and the back surface 510c of the auxiliary top plate 510 as needed, the front surface 210b and the back surface 210c that perform different functions can be selectively used.

[0060] In this fifth embodiment, a dovetail groove that functions as a holding means is provided on the top plate and a protruding portion is provided on the auxiliary top plate, but this is not limited to this and the auxiliary top plate may be provided with a dovetail groove and a protruding portion on the top plate. Also, the dovetail shape is not limited as long as the top plate and the auxiliary top plate can be fitted together to be slidable back and forth.

[0061] In addition, in this fifth embodiment, the convex portion 510e is press-fitted into the hole 52c to prevent the auxiliary top plate 520 from unintentionally sliding forward, but the mechanism for restricting the sliding movement of the auxiliary top plate can be freely changed. For example, a permanent magnet and a magnetic material may be disposed at the opposing portions of the auxiliary top plate and the top plate, respectively, and the sliding movement of the auxiliary top plate may be restricted by the magnetic attraction between them.

[0062] Although the embodiments of the present invention have been described above with reference to the drawings, the specific configuration is not limited to these embodiments, and the present invention also includes modifications and additions that do not deviate from the gist of the present invention.

[0063] For example, in the above embodiment, the top plate is exemplified as being square in plan view, but this is not limited to this, and the top plate may be rectangular in plan view, or may be a shape other than a square, such as a rectangle, or may be circular in plan view, or may be other than a rectangle.

[0064] Furthermore, the functional parts of the first to fifth embodiments may be used as the functional parts of the other embodiments. For example, the notched recess in the first embodiment may be used as the functional part of the auxiliary top plate in the second to fifth embodiments.

[0065] In the above embodiment, the holding means holds the auxiliary tabletop on both the left and right sides or both the front and rear sides, but this is not limiting, and the holding means may hold the auxiliary tabletop on either the left or right side or the front or rear side of the auxiliary tabletop. In other words, the holding means may hold the auxiliary tabletop on both sides so as to sandwich a portion of the auxiliary member.

[0066] In the above embodiment, the cutout portion and the auxiliary top plate are disposed on the front side of the table top, but this is not limiting, and the cutout portion and the auxiliary top plate may be disposed on the left, right, or rear side of the table top. Also, the cutout portion and the auxiliary top plate may be disposed in multiple locations on the table top.

[0067] In addition, in the above embodiment, the cutout portion and the auxiliary top plate are arranged in the center of the top plate in the left-right direction, but the cutout portion and the auxiliary top plate may also be arranged closer to the right or left side of the top plate.

[0068] In the above embodiment, the arrangement of the functional parts is changed by changing the attachment mode of one auxiliary top plate to the cutout portion, but it is also possible to prepare multiple types of auxiliary top plates with different functional parts and change the functional part by selecting the auxiliary top plate to fit into the cutout portion as needed. In this case, the cutout portion may be formed asymmetrically.

[0069] In addition, in the above embodiment, an example was given of a form in which the auxiliary top plate is fitted so that its periphery is flush with the periphery of the top plate, but it is also possible for a part of the auxiliary top plate to be fitted into the cutout portion so that it protrudes outward beyond the auxiliary top plate.
