Summary of the Invention

Problems to be Solved by the Invention

[0004] Furniture with a top plate such as the table disclosed in Patent Document 1 can be easily moved by providing casters on the legs that support the top plate. However, if casters are attached to all of the plurality of legs, all of the contact points between the furniture with the top plate and the floor surface will become rollers, and the furniture with the top plate may be moved with a small force, which may interfere with the work. For this reason, furniture with a top plate having legs provided with rollers and legs not provided with rollers has been proposed. In such furniture with a top plate, when movement is required, the top plate is lifted so that the legs not provided with rollers are separated from the floor surface, and the furniture is moved with only the legs provided with rollers in contact with the floor surface.

[0005] When lifting the top plate as described above, in some cases, the beam provided for reinforcement against the lower surface of the top plate may be gripped and lifted. However, such a beam has a rectangular cross-section. Therefore, when moving the furniture with the top plate, the corners of the beam may dig into the palm, causing discomfort to the operator.

[0006] This invention has been made in view of the above-mentioned problems, and aims to prevent workers from feeling uncomfortable when moving a fixture with a tabletop that is moved in a tilted state by lifting a part of the tabletop. [Means for solving the problem]

[0007] The present invention employs the following configuration as a means to solve the above problems.

[0008] A first aspect of the present invention is a fixture with a tabletop comprising: a tabletop having a portion including its outer edge that is a liftable portion; a plurality of legs that support the tabletop and are in contact with the floor surface; and a beam provided at least on the lower surface of the liftable portion, wherein the tabletop has a liftable portion which is a liftable edge; a plurality of legs that support the tabletop; and a beam provided at least on the lower surface of the liftable portion, wherein the legs include: a roller-equipped leg having a roller that is in contact with the floor surface while the liftable portion of the tabletop is lifted; and a roller-equipped leg positioned closer to the liftable portion than the roller-equipped leg and supporting the liftable portion of the tabletop The fixture has a separation leg that is separated from the floor surface when the top plate is lifted, and the beam is formed in such a shape that it extends from the upper part facing outward to the lower part facing downward, with an outer curved surface that curves so as to bulge between the upper part and the lower part, an inner plane that is bent and connected to the lower part of the outer curved surface and faces inward to the top plate, and an upper surface that is connected to the upper part of the outer curved surface and faces the lower surface of the top plate, and the fixture with a top plate can be tilted by gripping the beam provided on the lower surface of the part to be lifted and lifting it.

[0009] According to a first aspect of the present invention, the beam is provided with an outer curved surface. This outer curved surface is curved such that its upper part faces outward from the top plate in the horizontal direction and its lower part faces downward. Therefore, when a worker grasps the beam to lift the top plate, the worker's palm comes into contact with the outer curved surface. Thus, according to a first aspect of the present invention, when moving a fixture with a top plate by grasping the beam, it is possible to prevent the corners of the beam from digging into the worker's palm, thereby preventing the worker from feeling discomfort.

[0010] Furthermore, according to the first aspect of the present invention, the beam is provided with an inner plane. This inner plane is bent and connected to the lower part of the outer curved surface. As a result, the beam has a shape in which a corner is provided at the connection point between the outer curved surface and the inner plane. Such a corner can be hooked onto the knuckles of the worker when the palm is in contact with the outer curved surface as described above. When the corner of the beam is hooked onto the knuckles, the worker can firmly grasp the beam without feeling any discomfort, as the palm and pads of the fingers do not come into contact with the corner. Therefore, according to the first aspect of the present invention, it is possible to move the fixture with a top plate stably.

[0011] Furthermore, according to the first aspect of the present invention, when the worker is not lifting the portion of the top plate that is to be lifted, the separating legs are in contact with the floor surface, thus preventing the fixture with the top plate from being moved with weak force. Also, according to the first aspect of the present invention, when the worker lifts the portion of the top plate that is to be lifted, the separating legs are separated from the floor surface, and the rollers of the roller-equipped legs come into contact with the floor surface, so the fixture with the top plate can be easily moved.

[0012] A second aspect of the present invention is a configuration in which, in the first aspect, the top plate is formed in a rectangular shape having four sides, including one side included in the lifting portion, and the beams are provided along each of the sides, with their ends connected to each other to form a frame shape in plan view.

[0013] According to a second aspect of the present invention, one beam is located below the part to be lifted, and other beams are connected to each of the ends of this beam. The ends of the beam are the most difficult places for an operator to grip when lifting the top plate. By connecting other beams to the ends of such a beam, the possibility of an operator's hand touching another beam when gripping the beam below the part to be lifted can be reduced. Therefore, it is possible to prevent an operator's hand from touching another beam and feeling obstructed when trying to grip the beam below the part to be lifted.

[0014] Furthermore, according to a second aspect of the present invention, multiple beams form a frame shape. This makes it possible to increase the rigidity of the tabletop. Therefore, according to a second aspect of the present invention, when the tabletop is lifted, it is possible to prevent the tabletop from bending.

[0015] A third aspect of the present invention is, in the second aspect described above, comprising two roller-equipped legs arranged spaced apart in a direction along the edge included in the portion to be lifted, and two spaced-apart legs arranged spaced apart in a direction along the edge included in the portion to be lifted, wherein the roller-equipped legs and the spaced-apart legs are arranged spaced apart in a horizontal direction intersecting the direction along the edge included in the portion to be lifted.

[0016] According to a third aspect of the present invention, the two spaced-out legs are positioned spaced apart in a direction along the edge included in the part to be lifted. As a result, the feet of the worker lifting the tabletop at a position opposite the part to be lifted are positioned between the two spaced-out legs, preventing the worker's feet from coming into contact with the spaced-out legs. Therefore, according to the third aspect of the present invention, the movement of the furniture with a tabletop becomes easier.

[0017] A fourth aspect of the present invention is a configuration in which, in the third aspect described above, the distance from the roller-equipped leg to the spaced-out leg in the direction perpendicular to the direction along the edge included in the lifting target portion, among the direction along the lower surface of the top plate, is greater than the distance between the two roller-equipped legs and the distance between the two spaced-out leg bodies.

[0018] According to a fourth aspect of the present invention, the distance from the roller-equipped leg to the spaced-out leg is greater than the distance between roller-equipped legs or between spaced-out legs. Therefore, when the tabletop is lifted so that the spaced-out legs are separated from the floor, a longer distance can be secured from the worker to the roller-equipped leg, and the tilt angle of the tabletop can be kept small. Thus, according to the fourth aspect of the present invention, the tabletop-equipped fixture can be kept stable even when the tabletop is lifted.

[0019] A fifth aspect of the present invention is a configuration in which, in any of the second to fourth aspects, the top plate is formed in a rectangular shape having two long sides arranged parallel to each other and two short sides shorter than the long sides and arranged parallel to each other, and one of the short sides is included in the lifting target portion.

[0020] According to a fifth aspect of the present invention, when moving the fixture, the shorter side of the rectangular top plate is lifted in a plan view. Therefore, according to the fifth aspect of the present invention, the tipping of the fixture with the top plate can be prevented compared to the case where the longer side is lifted.

[0021] A sixth aspect of the present invention is a configuration in which, in any of the first to fifth aspects, the beam comprises a first plate member provided with the outer curved surface and a second plate member provided with at least a portion of the inner plane, and the boundary between the first plate member and the second plate member is positioned to overlap with the inner plane when viewed from the direction normal to the inner plane.

[0022] In the sixth aspect of the present invention, a beam can be formed by joining a first plate member and a second plate member. Therefore, for example, compared with the case of forming a beam by molding one cylindrical material or the like, the beam can be formed more easily. Further, the boundary portion between the first plate member and the second plate member is located on the inner plane. Therefore, it is possible to prevent the boundary portion between the first plate member and the second plate member from hitting the palm of the operator and prevent the operator from feeling discomfort.

Effects of the Invention

[0023] According to the present invention, in a top plate attachment device that is moved in an inclined state by lifting a part of the top plate, it is possible to suppress giving a sense of discomfort to the operator during movement.

[0025] Hereinafter, an embodiment of the fixture with a tabletop according to the present invention will be described with reference to the drawings. In the embodiments and modifications described below, corresponding components may be denoted by the same reference numerals and their descriptions may be omitted. In the following description, expressions indicating relative or absolute arrangements, such as "parallel" or "orthogonal," will not only strictly represent such arrangements but also represent states of relative displacement with tolerances or angles and distances that allow the same function to be obtained.

[0026] Figure 1 is a perspective view of the tabletop furniture unit 1 of this embodiment, seen from above. Figure 2 is a perspective view of the tabletop furniture unit 1 of this embodiment, seen from below. The tabletop furniture unit 1 of this embodiment is installed in various facilities such as offices, public facilities, and commercial facilities to provide workspace. As shown in Figures 1 and 2, the tabletop furniture unit 1 of this embodiment comprises a tabletop 2, legs 3, beams 4, and connecting members 5.

[0027] In this embodiment, the top plate 2 is formed in a rectangular shape when viewed from above. For the sake of explanation, in the following description, the horizontal direction along the longer side of the top plate 2 in the view from above will be referred to as the front-to-back direction, and the horizontal direction along the shorter side of the top plate 2 in the view from above will be referred to as the left-to-right direction. Also, as shown in Figure 1, one side in the front-to-back direction will be referred to as the front, the other side in the front-to-back direction as the rear, one side in the left-to-right direction as the right, and the other side in the left-to-right direction as the left. Furthermore, the vertical direction perpendicular to the front-to-back direction and the left-to-right direction will be referred to as the up-and-down direction.

[0028] The tabletop 2 is a rectangular plate-shaped member in plan view, supported by legs 3 so that its front and back surfaces face up and down. The top surface 2a of the tabletop 2 is the workspace for the worker. In other words, the tabletop 2 forms the workspace. In plan view, the tabletop 2 has four sides 2b (outer edges). Of these four sides 2b, two are relatively long sides 2c, and the remaining two are relatively short sides 2d. In other words, the length dimension of the long sides 2c is greater than the length dimension of the short sides 2d.

[0029] Each of the longer sides 2c is positioned along the front-to-back direction. These longer sides 2c are of the same length and are positioned parallel to each other, spaced apart in the left-to-right direction. Each of the shorter sides 2d is positioned along the left-to-right direction. These shorter sides 2d are of the same length and are positioned parallel to each other, spaced apart in the front-to-back direction.

[0030] The front end of the long side 2c on the right side is connected to the right end of the short side 2d located at the front. Also, the rear end of the long side 2c on the right side is connected to the right end of the short side 2d located at the rear. The front end of the long side 2c on the left side is connected to the left end of the short side 2d located at the front. Also, the rear end of the long side 2c on the left side is connected to the left end of the short side 2d located at the rear. The tabletop 2, having such four sides 2b in a plan view, is formed in a rectangular shape in a plan view as described above.

[0031] The front edge of the top plate 2 in the front-to-back direction is the part that can be lifted by an operator when moving the fixture with the top plate 1 (liftable portion 2e). In other words, the top plate 2 has a liftable edge, which is a liftable portion 2e. Of the four sides 2b mentioned above, the short side 2d located on the front side is located in this liftable portion 2e. In other words, in this embodiment, one of the four sides 2b is included in the liftable portion 2e. Also, one of the short sides 2d is included in the liftable portion 2e.

[0032] The lower surface 2f of the top plate 2 is the mounting surface for the beam 4 and the connecting member 5. In this embodiment, the lower surface 2f of the top plate 2 is flat. However, the lower surface 2f of the top plate 2 may have an uneven shape.

[0033] Note that the shape of the top plate 2 in this embodiment is just one example. The shape of the top plate 2 is not limited to the shape of this embodiment, and for example, it may be square in plan view. Furthermore, the plan view shape of the top plate 2 does not have to be rectangular, but may be circular, triangular, or a polygon with pentagons or more. Moreover, the plan view shape of the top plate 2 may be asymmetrical.

[0034] As shown in Figures 1 and 2, there are multiple legs 3. In other words, the tabletop furniture 1 of this embodiment is equipped with multiple legs 3. These legs 3 support the tabletop 2 from below. Each leg 3 is connected to the lower surface 2f of the tabletop 2 via a connecting member 5.

[0035] The tabletop fixture 1 of this embodiment has two types of legs 3: a roller-equipped leg 3a and an adjustable leg 3b (space-spreading leg). The tabletop fixture 1 of this embodiment has four legs 3 corresponding to each corner of the tabletop 2 in a plan view. Of these four legs 3, two are roller-equipped legs 3a, and the remaining two are adjustable legs 3b.

[0036] As shown in Figures 1 and 2, the roller-equipped legs 3a are legs 3 located behind the adjustable legs 3b. One roller-equipped leg 3a is located below the corner formed by the connection of the long side 2c on the right side of the top plate 2 and the short side 2d located at the rear. The other roller-equipped leg 3a is located below the corner formed by the connection of the long side 2c on the left side of the top plate 2 and the short side 2d located at the rear. These two roller-equipped legs 3a are spaced apart in the left-right direction along the short side 2d (in the direction along the side 2b included in the lifting target portion 2e).

[0037] Figure 3 is a schematic enlarged view of the lower end of the roller-equipped leg 3a. As shown in this figure, the roller-equipped leg 3a comprises a leg body portion 10 that extends in the vertical direction and a roller 11 that is rotatably attached to the leg body portion 10. The lower end surface 10a of the leg body portion 10 is a plane that can contact the floor surface F. When the portion of the tabletop 2 to be lifted 2e is not lifted and the upper surface 2a of the tabletop 2 is horizontal, the lower end surface 10a of the leg body portion 10 is in surface contact with the floor surface F.

[0038] The roller 11 is rotatably supported about an axis of rotation parallel to the left-right direction of the roller-equipped leg 3a, and is capable of rolling on the floor surface F. The roller 11 is mounted away from the floor surface F when the lifting target portion 2e of the top plate 2 is not lifted and the top surface 2a of the top plate 2 is horizontal. Alternatively, the roller 11 can be mounted in a position where it makes contact with the floor surface F, as shown by the dashed line in Figure 3, when the lifting target portion 2e of the top plate 2 is lifted and the top surface 2a of the top plate 2 is tilted.

[0039] Note that the configuration of the roller-equipped leg 3a shown in Figure 3 is just one example. For example, the roller-equipped leg may not have a lower end surface 10a that makes surface contact with the floor surface F, and the roller 11 may be in a configuration where it is in contact with the ground even when the lifted portion 2e of the top plate 2 is not lifted. In such a configuration, the roller 11 will be in contact with the ground whether the lifted portion 2e of the top plate 2 is not lifted or whether the lifted portion 2e of the top plate 2 is lifted.

[0040] As shown in Figures 1 and 2, the adjustable leg 3b is the leg 3 located in front of the roller leg 3a. In other words, the adjustable leg 3b is located closer to the lifted portion 2e than the roller leg 3a. One adjustable leg 3b is located below the corner formed by the connection of the long side 2c on the right side of the top plate 2 and the short side 2d located in front. The other adjustable leg 3b is located below the corner formed by the connection of the long side 2c on the left side of the top plate 2 and the short side 2d located in front. These two adjustable leg 3b are spaced apart in the left-right direction along the short side 2d (the direction along the side 2b included in the lifted portion 2e).

[0041] Figure 4 is a schematic enlarged view of the lower end of the adjustable leg 3b. As shown in this figure, the adjustable leg 3b comprises a leg body 20 that extends in the vertical direction and an adjuster 21 attached to the lower surface of the leg body 20. The lower surface of the adjuster 21 is the contact surface with the floor surface F. The distance from the lower surface of the leg body 20 to the lower surface of the adjuster 21 is adjustable.

[0042] With the adjustable leg 3b, the lower surface of the adjuster 21 is in surface contact with the floor surface F when the lifting target portion 2e of the tabletop 2 is not lifted and the upper surface 2a of the tabletop 2 is horizontal. On the other hand, with the adjustable leg 3b, the lifting target portion 2e of the tabletop 2 is lifted and the upper surface 2a of the tabletop 2 is tilted and the leg 3b is separated from the floor surface F.

[0043] As shown in Figures 1 and 2, the dimension La from the roller-equipped leg 3a to the adjuster-equipped leg 3b in the front-rear direction is greater than the dimension Lb between the two roller-equipped leg 3a in the left-right direction. Also, the dimension La from the roller-equipped leg 3a to the adjuster-equipped leg 3b in the front-rear direction is greater than the dimension Lc between the two adjuster-equipped leg 3b in the left-right direction. In this embodiment, however, the dimension Lb between the two roller-equipped leg 3a in the left-right direction is equal to the dimension Lc between the two adjuster-equipped leg 3b in the left-right direction.

[0044] The beam 4 is fixed to the underside of the top plate 2. Figure 5 is a bottom view of the top plate furniture 1 of this embodiment. As shown in this figure, in this embodiment, four beams 4 are provided, each fastened to the top plate 2 by screws 6.

[0045] The beams 4 are provided along each of the four sides 2b of the top plate 2. In other words, the top plate furniture 1 of this embodiment includes a beam 4 along the long side 2c on the left side of the top plate 2, a beam 4 along the long side 2c on the right side of the top plate 2, a beam 4 along the short side 2d on the front side of the top plate 2, and a beam 4 along the short side 2d on the rear side of the top plate 2. These beams 4 are connected to each other via connecting members 5 so as to form a frame shape in plan view. Such beams 4 improve the rigidity of the top plate 2 and prevent the top plate 2 from bending when it is lifted, etc.

[0046] Of these beams 4, the beam 4 along the short side 2d located on the front side of the top plate 2 is located in the lifting target portion 2e. The beam 4 located in the lifting target portion 2e can be gripped by the worker when lifting the lifting target portion 2e of the top plate 2. In the following description, the beam 4 located in the lifting target portion 2e will be referred to as the gripping beam 4a, as needed. In other words, the gripping beam 4a is used as a gripping part for the furniture that is gripped by the worker when moving the furniture with the top plate 1.

[0047] Figure 6 is a perspective view of the gripping beam 4a from the front. Figure 7 is a perspective view of the gripping beam 4a from the rear. Figure 8 is a cross-sectional view of AA in Figure 6. As shown in these figures, the gripping beam 4a comprises a main body portion 30 and an extension portion 31.

[0048] The main body 30 is formed in a cylindrical shape and is provided with an outer curved surface 32. The outer curved surface 32 is a curved surface having an upper part 32a that faces outward from the top plate 2 and a lower part 32b that faces downward. The outward side of the top plate 2 is the direction opposite to the center of the top plate 2 in a plan view, which is the front side in the case of the gripping beam 4a. In other words, in the case of the gripping beam 4a, the upper part 32a faces forward.

[0049] The outer curved surface 32 is curved so that no bend occurs from the upper part 32a to the lower part 32b. Such an outer curved surface 32 is curved so that the portion between the upper part 32a and the lower part 32b bulges forward and downward more than the line segment connecting the upper part 32a and the lower part 32b.

[0050] Furthermore, the main body 30 is provided with an inner plane 33. The inner plane 33 is a plane that faces inward towards the top plate 2. The inward side of the top plate 2 is the direction toward the center of the top plate 2 in a plan view, and in the case of the gripping beam 4a, it is the rear side. In other words, in the case of the gripping beam 4a, the inner plane 33 faces the rear side.

[0051] This inner plane 33 is bent and connected to the lower part 32b of the outer curved surface 32. This bent connection of the inner plane 33 to the lower part 32b of the outer curved surface 32 forms a corner portion 34 in the main body portion 30. As shown in Figures 6 and 7, the inner plane 33 is provided with screw insertion holes 33a. The screw insertion holes 33a are through holes through which screws (not shown) are inserted for fastening the connecting member 5 and the beam 4.

[0052] Furthermore, the main body 30 is provided with an upper surface 35. The upper surface 35 is oriented upward and is a surface connected to the upper part 32a of the outer curved surface 32 and the inner plane 33. This upper surface 35 faces the lower surface 2f of the top plate 2 and, in this embodiment, is in contact with the lower surface 2f of the top plate 2.

[0053] The extended portion 31 is a portion that extends from the upper end of the main body portion 30 (the inner end of the top plate 2 on the upper surface 35) in the direction in which the inner plane 33 is directed. In the gripping beam 4a, the inner plane 33 is directed towards the rear. Therefore, in the gripping beam 4a, the extended portion 31 extends from the main body portion 30 toward the rear.

[0054] The extension portion 31 has its front and back surfaces oriented vertically and is continuously provided over the entire length of the main body portion 30 (left and right direction in the case of the gripping beam 4a). As shown in Figures 6 and 7, the extension portion 31 is provided with screw insertion holes 31a. Multiple screw insertion holes 31a are provided so as to be arranged along the length of the main body portion 30. The screw insertion holes 31a are through holes through which screws 6 for fastening the beam 4 and the top plate 2 are inserted.

[0055] The extended portion 31 is fastened to the lower surface 2f of the top plate 2 by screws 6. By fastening the extended portion 31 to the top plate 2 in this way, the beam 4 is fixed to the top plate 2. In other words, in this embodiment, the beam 4 is fixed to the top plate 2 without screws being inserted through the main body portion 30.

[0056] Such a gripping beam 4a is formed by joining a first plate member 40 and a second plate member 41, as shown in Figure 8, for example. In other words, the gripping beam 4a has a first plate member 40 and a second plate member 41.

[0057] The first plate member 40 is formed by molding a flat plate member. As shown in Figure 8, the first plate member 40 has a curved front wall portion 40a that forms the outer curved surface 32 described above. The first plate member 40 also has a rear wall portion 40b that is erected from the lower end of the front wall portion 40a to form the lower part of the inner plane 33 described above. The first plate member 40 also has an upper wall portion 40c that extends rearward from the upper end of the front wall portion 40a to form the upper surface 35 and the extended piece portion 31 described above.

[0058] The second plate member 41 is formed by molding a flat plate member. As shown in Figure 8, the second plate member 41 has a vertical wall 41a that forms the upper part of the inner plane 33 described above. The second plate member 41 also has a contact wall 41b (contact portion) that contacts the first plate member 40 from the back side of the outer curved surface 32 (the rear side in the gripping beam 4a). The second plate member 41 has a connecting wall 41c that connects the vertical wall 41a and the contact wall 41b and contacts the upper wall portion 40c of the first plate member 40 from below.

[0059] The first plate member 40 and the second plate member 41 are joined within the inner plane 33. In other words, the boundary portion 42 between the first plate member 40 and the second plate member 41 is located within the inner plane 33. As shown in Figure 8, the boundary portion 42 is located below the center of the inner plane 33.

[0060] Furthermore, the beams 4, excluding the gripping beam 4a, are formed in the same shape as the gripping beam 4a. For example, the beam 4 below the short side 2d located on the rear side of the top plate 2 is formed in the same shape as the gripping beam 4a, except that its mounting position to the top plate 2 is different from that of the gripping beam 4a. Also, the beam 4 below the long side 2c located on the right side of the top plate 2 is formed in the same shape as the gripping beam 4a, except that the length dimension of the main body 30 in the extension direction is longer than that of the gripping beam 4a, and its mounting position to the top plate 2 is different from that of the gripping beam 4a. Also, the beam 4 below the long side 2c located on the left side of the top plate 2 is formed in the same shape as the gripping beam 4a, except that the length dimension of the main body 30 in the extension direction is longer than that of the gripping beam 4a, and its mounting position to the top plate 2 is different from that of the gripping beam 4a. For this reason, a detailed explanation of the beams 4, excluding the gripping beam 4a, will be omitted.

[0061] The connecting member 5 is fixed to the top plate 2 and connects the two beams 4 and the leg body 3. In a plan view, the connecting member 5 is positioned below each corner (the connection point between sides 2b) of the rectangular top plate 2. In other words, the furniture unit 1 with a top plate in this embodiment is equipped with four connecting members 5.

[0062] Figure 9 is a perspective view of the connecting member 5. As shown in this figure, the connecting member 5 has a base portion 50, an upper piece portion 51, two arm portions 52, and a leg body connecting portion 53. The base portion 50 is the part that supports the upper piece portion 51, the two arm portions 52, and the leg body connecting portion 53.

[0063] The upper piece 51 is a piece that extends from the upper end of the base 50 toward the inside of the top plate 2. As shown in Figure 9, the upper piece 51 is provided with screw insertion holes 51a. Multiple screw insertion holes 51a are provided. The screw insertion holes 51a are through holes through which screws 7 (see Figure 5) for fastening the connecting member 5 and the top plate 2 are inserted.

[0064] The arm portion 52 is the part that is inserted into the main body portion 30 of the beam 4. Two beams 4 are connected to one connecting member 5 from different directions. For this reason, the connecting member 5 is provided with two arm portions 52 that extend in different directions. Each arm portion 52 is provided with a screw hole. The beam 4 and the connecting member 5 are fixed together when the arm portion 52 is inserted into the main body portion 30 of the beam 4 and a screw (not shown) is screwed into the screw hole, which is inserted into a screw insertion hole 33a provided in the inner plane 33.

[0065] The leg connection portion 53 extends downward from the base portion 50 and is the part to which the leg body 3 is fixed. The leg body 3 is fixed to the leg connection portion 53 by, for example, screws (not shown) or a locking mechanism (not shown).

[0066] When moving the fixture 1 with a top plate of this embodiment, as shown in Figure 10, the worker grasps the gripping beam 4a. At this time, the worker's palm H1 touches the outer curved surface 32 of the gripping beam 4a. Also, the worker's knuckles H2 are on the corners 34. Then, while gripping the gripping beam 4a, the worker lifts the portion 2e of the top plate 2 that is to be lifted.

[0067] In Figure 10, the second joint of the worker's finger is shown resting on the corner 34. However, the worker may also rest the first joint (the joint closest to the fingertip) or the third joint (the joint at the base of the finger) on the corner 34. The worker can select which finger joint to rest on the corner 34 to best grip the gripping beam 4a, according to the size of their hand.

[0068] As a result, the entire unit with the tabletop 1 can be tilted, the adjustable legs 3b move away from the floor surface F, and the rollers 11 of the roller-equipped legs 3a make contact with the floor surface F. Therefore, the worker can easily move the unit with the tabletop 1 with little force.

[0069] The fixture with a top plate 1 of this embodiment comprises a top plate 2, legs 3, and a gripping beam 4a. The top plate 2 has a liftable edge portion 2e. Multiple legs 3 are provided to support the top plate 2. The gripping beam 4a is provided on the lower surface 2f of the liftable portion 2e. Furthermore, the fixture with a top plate 1 of this embodiment has a roller-equipped leg 3a as the leg 3, which has a roller 11 that makes contact with the floor surface F when the liftable portion 2e of the top plate 2 is lifted. Furthermore, the fixture with a top plate 1 of this embodiment has an adjustable leg 3b as the leg 3, which is located closer to the liftable portion 2e than the roller-equipped leg 3a and is spaced away from the floor surface F when the liftable portion 2e of the top plate 2 is lifted. Furthermore, the gripping beam 4a is formed to have an outer curved surface 32, an inner flat surface 33, and an upper surface 35. The outer curved surface 32 is curved from the upper part 32a facing outwards to the lower part 32b facing downwards on the top plate 2. The inner plane 33 is bent and connected to the lower part 32b of the outer curved surface 32 and faces inwards on the top plate 2. The top surface 35 is connected to the upper part 32a of the outer curved surface 32 and faces the bottom surface 2f of the top plate 2.

[0070] In the tabletop-equipped furniture unit 1 of this embodiment, the gripping beam 4a is provided with an outer curved surface 32. This outer curved surface 32 is curved such that the upper part 32a faces outward from the tabletop 2 in the horizontal direction, and the lower part 32b faces downward. Therefore, when a worker grips the gripping beam 4a to lift the tabletop 2, the worker's palm H1 comes into contact with the outer curved surface 32. Thus, in the tabletop-equipped furniture unit 1 of this embodiment, when the gripping beam 4a is gripped and the tabletop-equipped furniture unit 1 is moved, the corners 34 of the gripping beam 4a are prevented from digging into the worker's palm H1, preventing the worker from feeling discomfort.

[0071] Furthermore, according to the top-mounted fixture 1 of this embodiment, the gripping beam 4a is provided with an inner surface 33. This inner surface 33 is bent and connected to the lower part 32b of the outer curved surface 32. As a result, the gripping beam 4a has a shape in which a corner portion 34 is provided at the connection point between the outer curved surface 32 and the inner surface 33. Such a corner portion 34 can be hooked onto the knuckles H2 of the worker when the palm H1 is in contact with the outer curved surface 32 as described above. When the corner portion 34 of the gripping beam 4a is hooked onto the knuckles H2, the worker's palm H1 and the pads of their fingers do not come into contact with the corner portion 34, so they can firmly grip the gripping beam 4a without feeling any discomfort. Therefore, according to the top-mounted fixture 1 of this embodiment, it is possible to move the top-mounted fixture 1 stably.

[0072] Furthermore, with the tabletop-equipped fixture 1 of this embodiment, when the worker is not lifting the liftable portion 2e of the tabletop 2, the adjustable legs 3b are in contact with the floor surface F, thus preventing the tabletop-equipped fixture 1 from being moved with weak force. Also, with the tabletop-equipped fixture 1 of this embodiment, when the worker lifts the liftable portion 2e of the tabletop 2, the adjustable legs 3b are separated from the floor surface F, and the rollers 11 of the roller-equipped legs 3a are in contact with the floor surface F, so the tabletop-equipped fixture 1 can be easily moved.

[0073] Furthermore, in the fixture with a top plate 1 of this embodiment, the top plate 2 is formed in a rectangular shape having four sides 2b, including one side that is included in the lifting target portion 2e. The gripping beams 4a are provided along each side 2b, and their ends are connected to each other so as to form a frame shape in plan view.

[0074] In this embodiment of the tabletop-equipped fixture 1, one gripping beam 4a is located below the lifting target portion 2e, and other beams 4 are connected to each of the ends of this gripping beam 4a. The ends of the gripping beam 4a are the most difficult places for an operator to grip when lifting the tabletop 2. By connecting other beams 4 to both ends of this gripping beam 4a, the possibility of an operator's hand touching other beams 4 when gripping the gripping beam 4a below the lifting target portion 2e can be reduced. Therefore, it is possible to prevent an operator's hand from touching other beams 4 when trying to grip the gripping beam 4a below the lifting target portion 2e, thus preventing the operator from feeling obstructed.

[0075] Furthermore, in the fixture with a top plate 1 of this embodiment, the multiple gripping beams 4a form a frame shape. This makes it possible to increase the rigidity of the top plate 2. Therefore, in the fixture with a top plate 1 of this embodiment, it is possible to prevent the top plate 2 from bending when it is lifted.

[0076] Furthermore, the fixture with a top plate 1 of this embodiment includes two roller-equipped legs 3a arranged spaced apart in the direction along the edge 2b included in the lifting target portion 2e (left-right direction). Furthermore, the fixture with a top plate 1 of this embodiment includes two adjustable legs 3b arranged spaced apart in the direction along the edge included in the lifting target portion 2e.

[0077] In the tabletop-equipped furniture unit 1 of this embodiment, the two adjustable legs 3b are spaced apart in a direction along the edge included in the lifting target portion 2e. Therefore, the feet of the worker lifting the tabletop 2 at a position facing the lifting target portion 2e are positioned between the two adjustable legs 3b, preventing the worker's feet from coming into contact with the adjustable legs 3b. Consequently, the tabletop-equipped furniture unit 1 of this embodiment facilitates the movement of the tabletop-equipped furniture unit 1.

[0078] Furthermore, in the fixture with a top plate 1 of this embodiment, the dimension La from the roller-equipped leg 3a to the adjustable leg 3b in the direction perpendicular to the direction along the edge 2b included in the lifted portion 2e (front-to-back direction) along the lower surface 2f of the top plate 2 is greater than the dimension Lb between the two roller-equipped legs 3a. Also, the above dimension La is greater than the dimension Lc between the two adjustable leg 3b.

[0079] In the tabletop-equipped fixture 1 of this embodiment, the dimension La from the roller-equipped leg 3a to the adjustable leg 3b is larger than the dimension Lb between the roller-equipped legs 3a and the dimension Lc between the adjustable leg 3b. Therefore, when the tabletop 2 is lifted so that the adjustable leg 3b is separated from the floor surface F, a longer distance can be secured from the worker to the roller-equipped leg 3a, and the inclination angle of the tabletop 2 can be kept small. Consequently, in the tabletop-equipped fixture 1 of this embodiment, the tabletop-equipped fixture 1 can be kept stable even when the tabletop 2 is lifted.

[0080] Furthermore, in the fixture with a top plate 1 of this embodiment, the top plate 2 is formed in a rectangular shape with two long sides 2c arranged parallel to each other as sides 2b, and two short sides 2d that are shorter than the long sides 2c and also arranged parallel to each other. In addition, one of the short sides 2d is included in the liftable portion 2e.

[0081] In this embodiment of the fixture with a top plate 1, when moving it, the shorter side 2d of the rectangular top plate 2 is lifted in a plan view. Therefore, in this embodiment of the fixture with a top plate 1, compared to lifting the longer side 2c, the risk of the fixture with a top plate 1 tipping over can be suppressed.

[0082] Furthermore, in the fixture with a top plate 1 of this embodiment, the gripping beam 4a comprises a first plate member 40 provided with an outer curved surface 32, and a second plate member 41 provided with at least a portion of the inner plane 33. The boundary portion 42 between the first plate member 40 and the second plate member 41 is located within the inner plane 33 when viewed from the direction normal to the inner plane 33.

[0083] In this embodiment, the top-mounted fixture 1 can form a gripping beam 4a by joining a first plate member 40 and a second plate member 41. Therefore, compared to the case where the gripping beam 4a is formed by molding, for example, a single cylindrical material, the gripping beam 4a can be formed more easily. Furthermore, the boundary portion 42 between the first plate member 40 and the second plate member 41 is located on the inner plane 33. Therefore, it is possible to prevent the boundary portion 42 between the first plate member 40 and the second plate member 41 from coming into contact with the worker's palm H1, thus preventing the worker from feeling discomfort.
