Description

[Technical field]

[0001] This disclosure relates to a technique for stably installing movable fixtures on a floor surface. [Background technology]

[0002] Conventionally, when a movable fixture with casters on its underside is installed on a floor, a technique has been disclosed in which the ground contact member is displaced below the casters to support the fixture body (see, for example, Patent Document 1). Also, a technique has been disclosed for improving the stability of a fixture when installed on a floor (see, for example, Patent Document 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Publication No. 8-3610 [Patent Document 2] Japanese Patent Application Publication No. 11-46910 Summary of the Invention [Problem to be solved by the invention]

[0004] Patent Document 1 describes a configuration in which the adjuster can be adjusted from inside the fixture with the top cover open. With this configuration, it is difficult to fix the adjuster to the outer edge of the fixture. Therefore, when the above configuration is applied to a fixture that is long in the vertical direction, it is necessary to improve stability to prevent it from falling over when subjected to vibrations such as earthquakes.

[0005] On the other hand, Patent Document 2 describes a configuration in which a tip-prevention plate is placed on the underside of the fixture to improve stability when the fixture is placed on the floor. With this configuration, the tip-prevention plate protrudes outward from the fixture body, so there is a risk of tripping on the step between the floor and the tip-prevention plate, making it unsafe. In addition, the tip-prevention plate mars the appearance of the fixture, reducing its design value. Furthermore, casters and the like cannot be provided, making it impossible to make the fixture mobile.

[0006] Therefore, an object of the present disclosure is to provide movable fixtures equipped with casters that improve stability and safety when installed, while also achieving high design quality. [Means for solving the problem]

[0007] A movable fixture according to a first aspect of the present invention comprises a fixture main body having a bottom plate, a plurality of casters fixed to the underside of the bottom plate, and a plurality of ground contact members provided on the bottom plate such that their extension lengths from the underside are adjustable, and by adjusting the extension lengths of the ground contact members from the underside, the fixture can be transformed between a movable state in which the casters contact the floor surface and an immovable state in which the casters are separated from the floor surface, and the ground contact members comprise a plate member that contacts the floor surface and a bolt portion fixed perpendicular to the plate member, and the plate member is formed in a non-circular shape in a plan view, extends from an axis of the bolt portion towards the outside of the fixture main body, and is arranged within the range of the outline of the fixture main body in a plan view. An adjuster is provided on the bottom plate between the pair of ground contact members so that the extension length from the lower surface can be adjusted.

[0008] According to the movable fixture of the first aspect, since the plate member extends toward the outside of the fixture body, it is possible to improve the stability of the movable fixture when it is installed on the floor even if the grounding member is fixed to a part other than the outer edge of the fixture. Also, since the plate member is arranged within the range of the outer shape of the fixture body, there is no risk of tripping over the step caused by the plate member, and a high level of design can be achieved. Furthermore, by providing casters, the fixture body can be made mobile. In addition, the load of the fixture body can be distributed between the ground contact member and the adjuster, further improving stability when the fixture is immovable.

[0009] As the movable fixture according to the first aspect, any fixture equipped with casters and ground-contact members, such as individual booths, cabinets, clothing cases, tableware cases, display cases, etc., can be generally used.

[0013] In the movable fixture relating to the second aspect above, when the fixture body is formed into an approximately square shape in a plan view, either the front-to-back direction or the left-to-right direction of the fixture body can be defined as the short side direction.

[0014] A movable fixture according to a third aspect of the present invention is a movable fixture according to the first or second aspect, wherein the length of the plate member in the short direction of the fixture body is less than the short dimension of the fixture body and is greater than or equal to the short dimension of the internal space of the fixture body.

[0015] According to the movable fixture of the third aspect, the design of the movable fixture can be improved by making the dimensions of the plate member smaller than the dimensions of the fixture body. Also, by making the dimensions of the plate member larger than the dimensions of the internal space of the fixture body, the movable fixture is less likely to tip over, improving safety.

[0016] A movable fixture according to a fourth aspect of the present invention is a movable fixture according to any one of the first to third aspects, wherein the caster is arranged inside the plate member when viewed in a plan view, and the plate member is eccentrically arranged on the opposite side of the caster with respect to the axis of the bolt portion.

[0017] According to the movable fixture of the fourth aspect described above, the casters can be positioned further outward within a limited space, thereby improving stability when in a movable state.

[0018] The present invention Fifth viewpoint The movable fixtures related to Any one of the first to fourth aspects In the movable fixture relating to the above, the grounding member is a single plate member fixed to the bottom plate at two or more points.

[0019] the above Fifth viewpoint According to the movable fixture of the present invention, the connection strength of the grounding member to the fixture body can be increased, thereby further improving the stability of the movable fixture.

[0020] The present invention Sixth viewpoint The movable fixtures related to Any one of the first to fifth aspects In the movable fixture relating to the above, the grounding member has a bolt portion fixed perpendicular to the plate member, a through hole through the bottom plate through which the bolt portion can be inserted is formed, a lower nut provided on the underside of the bottom plate and an upper nut provided on the upper side of the bottom plate are screwed onto the bolt portion, and the grounding member is fixed to the bottom plate by sandwiching the bottom plate between the lower nut and the upper nut.

[0021] the above Sixth viewpoint According to the movable fixture described above, the vertical position of the ground contact member can be adjusted without rotating the plate member and the bolt portion, and the ground contact member can be easily attached to the fixture body.

[0022] The present invention Seventh viewpoint The movable fixtures related to Sixth viewpoint In the movable fixture relating to the present invention, a recess for accommodating the upper nut is formed on the upper surface of the bottom plate.

[0023] the above Seventh viewpoint According to the movable fixture of the present invention, the upper nut does not protrude from the top surface of the base plate, thereby improving the usability of the internal space of the fixture body. Effect of the Invention

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0033] [First embodiment: movable fixture 1] The movable fixture 1 according to the first embodiment of the present invention will be described below with reference to Figures 1 to 6. In this embodiment, the direction of the movable fixture 1 is defined by the arrow in Figure 1. The movable fixture 1 according to this embodiment is placed on floor surface F as shown in Figure 1, and is an individual booth for use indoors by one person or a small number of people.

[0034] 1 and 2, the movable fixture 1 according to this embodiment comprises a fixture main body 10, eight casters 21, four adjusters 31, and two ground contact members 32. In the movable fixture 1, the casters 21, the adjusters 31, and the ground contact members 32 are positioned so as not to interfere with each other.

[0035] In this embodiment, eight casters 21 are provided on the movable fixture 1, but the number of casters 21 is not limited as long as the movable fixture 1 can be moved. Similarly, the number of adjusters 31 and ground members 32 is not limited as long as the movable fixture 1 can be stably installed. However, in order to reliably separate the casters 21 from the floor surface F in the immovable state described below, it is preferable to have the same number of casters 21 as the adjusters 31 and ground members 32 and to place the casters 21 near the adjusters 31 and ground members 32 as shown in FIG.

[0036] The fixture body 10 is formed into a box shape that is rectangular in front, top, and side views by combining multiple metal plates, etc. In this embodiment, the fixture body 10 is formed into a shape that is longer in the left-right direction than in the front-to-back direction in a top view. Hereinafter, the front-to-back direction of the movable fixture 1 will be appropriately referred to as the "short side direction of the fixture body 10."

[0037] The fixture body 10 is a rectangular tubular member having a bottom plate 11, a top plate 12, a right side plate 13, and a left side plate 14, and is provided with a front glass plate 15 at the front side and a rear glass plate 16 at the rear side. In the fixture body 10, an internal space R is formed, which is partitioned by the bottom plate 11, the top plate 12, the right side plate 13, the left side plate 14, the front glass plate 15, and the rear glass plate 16. As shown in Figures 3 to 5, the upper surface 11u of the bottom plate 11 in the internal space R is covered with a covering sheet S.

[0038] The front glass panel 15 is provided with a door frame 15a and a door member 15b that is connected to the door frame 15a so as to be able to open and close. A user of the movable fixture 1 can enter and exit the indoor space R by opening and closing the door member 15b. In this embodiment, the door member 15b is provided only on the front glass panel 15, but it is also possible to provide a door member on the rear glass panel 16 so as to allow entry and exit from both the front and rear.

[0039] In the movable fixture 1 according to this embodiment, casters 21 are fixed to the underside 11d of the bottom plate 11. In addition, an adjuster 31 and a ground contact member 32 that can adjust the extension length from the underside 11d are provided on the bottom plate 11. The movable fixture 1 can be transformed into a movable state or an immovable state by adjusting the extension length of the adjuster 31 and the ground contact member 32 from the underside 11d.

[0040] Specifically, as shown in Fig. 4(a), by making the extension length of the adjuster 31 and the ground contact member 32 from the lower surface 11d shorter than the extension length of the caster 21 from the lower surface 11d, the caster 21 is brought into a movable state in which it contacts the floor surface F. On the other hand, by making the extension length of the adjuster 31 and the ground contact member 32 from the lower surface 11d longer than the extension length of the caster 21 from the lower surface 11d, the caster 21 is separated from the floor surface F and brought into an immovable state.

[0041] 2 and 3, the adjuster 31 includes an adjuster bolt 31a and a metallic support plate 31b. The support plate 31b is a plate member that comes into contact with the floor surface F. The adjuster bolt 31a is a bolt portion that is fixed perpendicular to the support plate 31b. The adjuster 31 is fixed to the bottom plate 11 with two nut members, similar to the grounding member 32 described below, and the extension length from the lower surface 11d is adjustable.

[0042] 2, 3 and 6, each grounding member 32 includes two bolt portions 32a and a metal plate member 32b that is in contact with the floor surface F. The bolt portions 32a are fixed perpendicular to the plate member 32b.

[0043] As shown in Fig. 2, the plate member 32b is formed in a rectangular shape that is non-circular in a plan view. Moreover, the plate member 32b extends toward the front and rear edges, which are the outside of the fixture main body 10. Specifically, as shown in Fig. 2, the front end of the plate member 32b is disposed near the front edge of the fixture main body 10, and the rear end of the plate member 32b is disposed near the rear edge of the fixture main body 10.

[0044] The grounding member 32 is fixed to the bottom plate 11 with a lower nut 33 and an upper nut 34, and the extension length from the lower surface 11d is adjustable. Specifically, as shown in Figures 4 and 5, an insertion hole 11h through which the bolt portion 32a can be inserted is formed in the bottom plate 11.

[0045] Further, a lower nut 33 provided on the lower side of the bottom plate 11 and an upper nut 34 provided on the upper side of the bottom plate 11 are screwed onto the bolt portion 32a. The grounding member 32 is fixed to the bottom plate 11 by sandwiching the bottom plate 11 between the lower nut 33 and the upper nut 34. In this embodiment, a recess 11a for accommodating the upper nut 34 is formed in the upper surface 11u of the bottom plate 11.

[0046] In this embodiment, two bolt portions 32a are provided on the grounding member 32. That is, the grounding member 32 is fixed at two locations to the bottom plate 11 by a single plate member 32b. In this embodiment, as shown in Fig. 2, the bolt portion 32a of the grounding member 32 and the adjuster bolt 31a of the adjuster 31 are fixed to the bottom plate 11 on the inner side of the caster 21 in the short direction of the fixture main body 10.

[0047] When the movable fixture 1 is made movable or immovable, the vertical positions of the adjuster 31 and the ground member 32 are displaced. Below, the case where the ground member 32 is displaced will be described, but since the configuration for displacing the adjuster 31 is similar to that of the ground member 32, a detailed description will be omitted.

[0048] When the movable fixture 1 is made movable, as shown in Fig. 4(a), the lower nut 33 is brought close to the plate member 32b and the upper nut 34 is rotated, so that the ground contact member 32 is positioned upward. This reduces the extension length of the ground contact member 32 from the lower surface 11d, and the plate member 32b is separated from the floor surface F. In other words, the caster 21 touches the floor surface F, so that the movable fixture 1 becomes movable (movable state).

[0049] To immobilize the movable fixture 1, the upper nut 34 is rotated and displaced to the top of the bolt portion 32a, as shown in Fig. 4(b). This displaces the ground contact member 32 downward, and the plate member 32b abuts against the floor surface F (intermediate state). Furthermore, by rotating the lower nut 33, the ground contact member 32 is displaced downward. This increases the extension length of the ground contact member 32 from the bottom surface 11d, and as shown in Fig. 5, the caster 21 moves away from the floor surface F, making the movable fixture 1 immobile (immobile state).

[0050] In the movable fixture 1 according to this embodiment, as shown in Fig. 2, the plate member 32b of the grounding member 32 is disposed within the range of the outer shape of the fixture main body 10 in a plan view. Specifically, the plate member 32b is formed in a shape that extends in the short direction of the fixture main body 10 (the front-to-rear direction in the movable fixture 1) in a plan view. The length of the plate member 32b in the short direction of the fixture main body 10 is formed so as to be equal to or less than the short dimension of the fixture main body 10 (first dimension L1 in Fig. 2) and equal to or greater than the short dimension of the internal space R of the fixture main body 10 (second dimension L2 in Fig. 2).

[0051] As described above, according to the movable fixture 1 of this embodiment, the plate member 32b of the grounding member 32 extends toward the outside of the fixture body 10. For this reason, even when the bolt portion 32a of the grounding member 32 is fixed to a portion other than the outer edge of the movable fixture 1 as in this embodiment, it is possible to improve the stability when installing the movable fixture 1 on the floor surface F.

[0052] Furthermore, according to the movable fixture 1 of this embodiment, the casters 21 can be grounded on the floor surface F to enable movement, thereby making the fixture movable. Also, since the plate members 32b are arranged within the range of the outer shape of the fixture main body 10 in a plan view, there is no risk of tripping over a step caused by the plate members 32b. Also, since the plate members 32b can be configured so that they do not protrude outside the fixture main body 10, the design of the movable fixture 1 can be improved.

[0053] Furthermore, according to the movable fixture 1 of this embodiment, the plate member 32b is formed in a shape that extends in the short-side direction of the fixture main body 10 in a plan view, which makes it difficult for the movable fixture 1 to tip over in the short-side direction. This further improves the stability of the movable fixture 1 when installed on the floor surface F. Note that, when the fixture main body 110 is formed in a substantially square shape in a plan view, like the movable fixture 100 of the second embodiment described below, the short-side direction of the fixture main body 110 may be either the front-to-back direction or the left-to-right direction.

[0054] Moreover, according to the movable fixture 1 of this embodiment, the length of the plate member 32b is configured to be equal to or less than the short dimension of the fixture main body 10 and equal to or greater than the short dimension of the internal space R of the fixture main body 10. In this way, by making the dimension of the plate member 32b smaller than the dimension of the fixture main body 10, the design of the movable fixture 1 can be improved. Also, by making the dimension of the plate member 32b larger than the dimension of the internal space R of the fixture main body 10, the movable fixture 1 is made less likely to tip over, improving safety.

[0055] In the movable fixture 1 according to this embodiment, as shown in Fig. 2, the caster 21 is disposed on the inside in the left-right direction of the plate member 32b in a plan view. As shown in Figs. 4 and 5, the plate member 32b is provided eccentrically on the opposite side of the caster 21 with respect to the axis of the bolt portion 32a. This allows the caster 21 to be disposed further outward within the limited space on the lower surface 11d of the bottom plate 11. This improves the stability of the movable fixture 1 in a movable state.

[0056] 2, in the movable fixture 1 according to this embodiment, an adjuster 31 is provided between a pair of left and right ground members 32, 32. This allows the load of the fixture body 10 to be distributed between the ground members 32 and the adjuster 31, thereby further improving the stability of the movable fixture 1 when it is immovable.

[0057] Furthermore, the grounding member 32 of the movable fixture 1 according to this embodiment is a single plate member 32b fixed to the bottom plate 11 by two bolts 32a. This increases the connection strength of the plate member 32b to the fixture body 10, thereby further improving the stability of the movable fixture 1.

[0058] In the movable fixture 1 according to this embodiment, a lower nut 33 provided on the lower side of the bottom plate 11 and an upper nut 34 provided on the upper side of the bottom plate 11 are screwed into the bolt portion 32a of the grounding member 32. The grounding member 32 is fixed to the bottom plate 11 by sandwiching the bottom plate 11 between the lower nut 33 and the upper nut 34.

[0059] This makes it possible to adjust the vertical position of the grounding member 32 by rotating the lower nut 33 and the upper nut 34, without rotating the plate member 32b and the bolt portion 32a. Also, since there is no need to rotate the grounding member 32 when attaching the grounding member 32 to the fixture body 10, the attachment work can be easily performed. In particular, when the grounding member 32 is fixed to the bottom plate 11 with two bolt portions 32a as in this embodiment, the grounding member 32 cannot be rotated, so a configuration in which the grounding member 32 is attached with two nuts as in this configuration is preferable.

[0060] In the movable fixture 1 according to this embodiment, a recess 11a for accommodating the upper nut 34 is formed on the upper surface of the bottom plate 11. This allows the upper nut 34 to be disposed below the upper surface 11u of the bottom plate 11, improving the usability of the internal space of the fixture body 10.

[0061] [First embodiment (modification) - Movable fixture 1A] Next, a movable fixture 1A according to a modified example of the first embodiment will be described with reference to Figures 7(a) and (b). In this modified example, the shape of the grounding member 32A is different from that of the movable fixture 1 according to the first embodiment, but the other configurations are the same. Therefore, the following description will focus on the configuration of the grounding member 32A.

[0062] 7(a) and (b), a grounding member 32A according to this modified example includes one bolt portion 32a and a plate member 32b that comes into contact with a floor surface F. The bolt portion 32a is fixed perpendicular to the plate member 32b.

[0063] As shown in FIG. 7(b), the plate member 32b is formed in a rectangular shape that is non-circular in plan view. The plate member 32b extends toward the front and rear edges of the fixture body 10. Specifically, as shown in FIG. 7(a), the grounding member 32A is fixed to the front and rear sides of the fixture body 10. The front end of the plate member 32b in the front grounding member 32A is disposed near the front edge of the fixture body 10. The rear end of the plate member 32b in the rear grounding member 32A is disposed near the rear edge of the fixture body 10. In other words, the grounding member 32A according to this modification is formed in a shape in which the midway portion in the front-rear direction is cut off in the plate member 32b of the grounding member 32 according to the first embodiment.

[0064] When the movable fixture 1A is made movable or immovable, the vertical positions of the adjuster 31 and the ground contact member 32A are displaced, as in the movable fixture 1 according to the first embodiment. That is, the extension length of the ground contact member 32A from the lower surface 11d is reduced to bring the caster 21 into contact with the floor surface F, thereby making the movable fixture 1A movable. In addition, the extension length of the ground contact member 32A from the lower surface 11d is increased to move the caster 21 away from the floor surface F, thereby making the movable fixture 1A immovable.

[0065] As described above, in the movable fixture 1A according to this modified example, the plate member 32b of the grounding member 32A extends outward from the fixture body 10. For this reason, even when the bolt portion 32a of the grounding member 32A is fixed to a portion other than the outer edge of the movable fixture 1A as in this modified example, it is possible to maintain stability when the movable fixture 1A is installed on the floor surface F.

[0066] Moreover, according to the movable fixture 1A of this embodiment, the casters 21 can be grounded on the floor surface F to make it movable, thereby making it movable. Also, since the plate members 32b are arranged within the range of the outer shape of the fixture main body 10 in a plan view, there is no risk of tripping over a step caused by the plate members 32b. Also, since the plate members 32b can be configured so that they do not protrude outside the fixture main body 10, the design of the movable fixture 1A can be improved.

[0067] Like the grounding member 32A of the movable fixture 1A according to this modified example, it is also possible to configure one plate member 32b to be fixed to the bottom plate 11 by a single bolt portion 32a. This allows the configuration of the grounding member 32A to be compact, making it possible to reduce the manufacturing costs of the movable fixture 1A.

[0068] [Second embodiment: movable fixture 100] Next, a movable fixture 100 according to a second embodiment of the present invention will be described with reference to Fig. 8 to Fig. 10. In this embodiment, the direction of the movable fixture 100 is defined by the arrow in Fig. 8. The movable fixture 100 according to this embodiment is placed on floor surface F as shown in Fig. 8, and is an individual booth for use mainly by one person in the room.

[0069] 8 and 9(a), the movable fixture 100 according to this embodiment includes a fixture body 110, four casters 121, and four ground contact members 132. In the movable fixture 100, the casters 121 and the ground contact members 132 are provided at positions where they do not interfere with each other.

[0070] In this embodiment, four casters 121 are provided on the movable fixture 100, but the number of casters 121 is not limited as long as the movable fixture 100 can be moved. Similarly, the number of grounding members 132 is not limited as long as the movable fixture 100 can be stably installed.

[0071] The fixture body 110 is formed into a box shape that is rectangular in front, top, and side views by combining multiple metal plates, etc. In this embodiment, the fixture body 110 is formed into a square shape that is approximately the same in the left-right direction and the front-back direction in a plan view.

[0072] The fixture body 110 is a square tubular member having a bottom plate 111, a top plate 112, a right side plate 113, and a left side plate 114. A front glass plate 115 is provided at the front side of the square tubular member, and a rear glass plate 116 is provided at the rear side. The front glass plate 115 is composed of a door frame 115a and a door member 115b connected to the door frame 115a so as to be openable and closable. In the fixture body 110, an internal space R is formed, which is partitioned by the bottom plate 111, the top plate 112, the right side plate 113, the left side plate 114, the front glass plate 115, and the rear glass plate 116. As shown in FIG. 8 and FIG. 9(a), the upper surface 111u of the bottom plate 111 in the internal space R is covered with a covering sheet S.

[0073] In the movable fixture 100 according to this embodiment, casters 121 are fixed to the underside 111d of the bottom plate 111. In addition, a ground contact member 132 whose extension length from the underside 111d is adjustable is provided on the bottom plate 111. The movable fixture 100 can be transformed between a movable state and an immovable state by adjusting the extension length of the ground contact member 132 from the underside 111d.

[0074] 10, by making the extension length of the ground contact member 132 from the lower surface 111d shorter than the extension length of the caster 121 from the lower surface 111d, the caster 121 is brought into a movable state in which it contacts the floor surface F. On the other hand, by making the extension length of the ground contact member 132 from the lower surface 111d longer than the extension length of the caster 121 from the lower surface 111d, the caster 121 is separated from the floor surface F and brought into an immovable state.

[0075] 9(b), each grounding member 132 includes one bolt portion 132a and a plate member 132b that comes into contact with the floor surface F. The bolt portion 132a is fixed perpendicular to the plate member 132b.

[0076] As shown in Figures 9(a) and (b), the plate member 132b in this embodiment is formed in a non-circular, generally L-shape in plan view. Each plate member 132b extends outward from the fixture body 110. Specifically, as shown in Figure 9(a), the plate members 132b are provided near the four corners of the fixture body 110 in plan view. Each plate member 132b extends toward two adjacent edges of the fixture body 110. For example, the plate member 132b provided on the front right side extends toward the front edge and the right edge of the fixture body 110.

[0077] The grounding member 132 is fixed to the bottom plate 111 with a lower nut 133 and an upper nut 134, and the extension length from the lower surface 111d is adjustable. Specifically, as shown in Fig. 10, an insertion hole 111h through which the bolt portion 132a can be inserted is formed in the bottom plate 111.

[0078] Further, a lower nut 133 provided on the underside of the bottom plate 111 and an upper nut 134 provided on the upper side of the bottom plate 111 are screwed into the bolt portion 132a. The grounding member 132 is fixed to the bottom plate 111 by sandwiching the bottom plate 111 between the lower nut 133 and the upper nut 134. In this embodiment, a recess 111a that accommodates the upper nut 134 is formed on the upper surface 111u of the bottom plate 111. When the movable fixture 100 is to be put into a movable state or an immovable state, the vertical position of the grounding member 132 is displaced, similar to the movable fixture 1 according to the first embodiment.

[0079] 9(a), in the movable fixture 100 according to this embodiment, the plate member 132b of the grounding member 132 is disposed within the range of the outer shape of the fixture body 110 in a plan view. Furthermore, the plate member 132b of the grounding member 132 extends toward the outside of the fixture body 110. For this reason, even when the bolt portion 132a of the grounding member 132 is fixed to a portion other than the outer edge of the movable fixture 100 as in this embodiment, it is possible to maintain stability when installing the movable fixture 100 on the floor surface F.

[0080] Furthermore, according to the movable fixture 100 of this embodiment, the casters 121 are placed in contact with the floor surface F to enable movement, thereby making the fixture movable. Also, since the plate members 132b are arranged within the range of the external shape of the fixture main body 100 in a plan view, there is no risk of tripping over a step caused by the plate members 132b. Also, since the plate members 132b can be configured so that they do not protrude outside the fixture main body 110, the design of the movable fixture 100 can be improved.

[0081] Furthermore, according to the movable fixture 100 of this embodiment, the plate member 132b is formed in a shape that extends in both the front-rear and left-right directions of the fixture main body 110 in a plan view, making it possible to make the movable fixture 100 less likely to tip over in all directions. This further improves the stability of the movable fixture 100 when installed on the floor surface F. When the fixture main body 110 is configured to be substantially square in a plan view as in this embodiment, it is preferable to give the fixture main body 110 a shape that extends in both the front-rear and left-right directions, like the plate member 132b.

[0082] Moreover, according to the movable fixture 100 of this embodiment, the length of the plate member 132b is configured to be equal to or less than the outer dimensions of the fixture main body 110 and equal to or greater than the outer dimensions of the internal space R of the fixture main body 110. In this way, by making the dimensions of the plate member 132b smaller than the dimensions of the fixture main body 110, the plate member 132b does not protrude from the fixture main body 110, thereby improving the design of the movable fixture 100. Furthermore, by making the dimensions of the plate member 132b larger than the dimensions of the internal space R of the fixture main body 110, the movable fixture 100 is made less likely to tip over, improving safety.

[0083] [Second embodiment (modification) - movable fixture 100A] Next, a movable fixture 100A according to a modified example of the second embodiment will be described with reference to Figures 11(a) and (b). In this modified example, the shape of the grounding member 132A is different from that of the movable fixture 100 according to the second embodiment, but the other configurations are the same. Therefore, the following description will focus on the configuration of the grounding member 132A.

[0084] 11(a) and (b), a grounding member 132A according to this modified example includes one bolt portion 132a and a plate member 132b that comes into contact with the floor surface F. The bolt portion 132a is fixed perpendicular to the plate member 132b.

[0085] As shown in Figures 11(a) and (b), the plate member 132b in this embodiment is formed in a rectangular shape that is non-circular in plan view. Furthermore, each plate member 132b extends toward the outside of the fixture main body 110. Specifically, as shown in Figure 11(a), the plate members 132b are provided near the four corners of the fixture main body 110 in plan view. Each plate member 132b extends toward one of the four corners of the fixture main body 110. For example, the plate member 132b provided on the front right side extends toward the right front corner of the fixture main body 110.

[0086] When the movable fixture 100A is made movable or immovable, the vertical position of the grounding member 132A is displaced, as in the movable fixture 100 according to the second embodiment. That is, the extension length of the grounding member 132A from the lower surface 111d is reduced to bring the caster 121 into contact with the floor surface F, thereby making the movable fixture 100A movable. In addition, the extension length of the grounding member 132A from the lower surface 111d is increased to move the caster 121 away from the floor surface F, thereby making the movable fixture 100A immovable.

[0087] As described above, in the movable fixture 100A according to this modified example, the plate members 132b of the grounding member 132A extend toward the four corners of the fixture body 110. For this reason, even when the bolt portions 132a of the grounding member 132A are fixed to a portion other than the outer edge of the movable fixture 100A as in this modified example, it is possible to maintain stability when the movable fixture 100A is installed on the floor surface F.

[0088] Moreover, according to the movable fixture 100A of this embodiment, the casters 121 are placed in contact with the floor surface F to enable movement, thereby making the fixture movable. Also, since the plate members 132b are arranged within the range of the outer shape of the fixture main body 100 in a plan view, there is no risk of tripping over a step caused by the plate members 132b. Also, since the plate members 132b can be configured not to protrude outside the fixture main body 110, the design of the movable fixture 100A can be improved.

[0089] [Other variations] The above embodiment can be modified as appropriate as shown in the other modified examples shown below. Each modified example described in this specification may be applied in combination with other modified examples to the extent that no contradiction occurs.

[0090] As movable fixtures according to the present invention, general fixtures equipped with casters and ground-contact members, such as individual booths, cabinets, clothing cases, tableware cases, and display cases, can be used.

[0091] The shape of the fixture body constituting the movable fixture in plan view may be other than rectangular. For example, the fixture body may be circular, triangular, pentagonal, trapezoidal, etc. in plan view.

[0092] The number and shape of the grounding members provided on the movable fixture may be configured other than those of this embodiment. For example, the grounding members 132 or 132A of the second embodiment may be applied to the movable fixture 1 of the first embodiment. Also, instead of the adjuster 31 in the movable fixture 1 of the first embodiment, the grounding members 32A according to the modified example of the first embodiment may be provided.

[0093] In addition, the plate member only needs to extend toward at least one outer edge of the fixture body in a plan view, and it is also possible for the plate member to extend toward two or more different outer edges. In addition, the plate member can be formed into a shape that extends in the longitudinal direction of the fixture body in a plan view, or in both the lateral and longitudinal directions.

[0094] In addition, the plate member can be not only rectangular or L-shaped as described in each of the above embodiments, but also other quadrangular shapes such as rhombus and trapezoid, other polygonal shapes such as triangle and pentagon, fan shape, U-shape, or other shapes other than circular.

[0095] Moreover, the method of fixing the grounding member to the bottom plate may be configured in a manner other than that of the present embodiment. For example, a method of fixing a bolt to the bottom plate and screwing the bolt into a nut fixed to the grounding member, a method of fixing a nut to the bottom plate and screwing the bolt fixed to the grounding member into the nut, or the like may be used.
