Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in the case of movable furniture as described in Patent Document 1, it is also conceivable to use it as a furniture system together with other structures by arranging the furniture adjacent to other structures. However, in the prior art, when a movable furniture item and another structure are arranged adjacent to each other, a gap may be formed between the movable furniture item and the other structure. In this case, for example, it is difficult to create a sense of unity as a furniture system. In addition, there is a possibility that light leaks to the front side of the furniture system through the gap, or the background of the furniture system can be seen from the front side of the furniture system through the gap. Therefore, in the conventional furniture system, there is still room for improvement in terms of improving the appearance.

[0005] The present invention aims to provide a furniture system that can improve the appearance of a movable furniture unit by making it difficult for gaps to form between the movable furniture unit and other structures when the movable furniture unit is placed adjacent to other structures, as viewed from the front. [Means for solving the problem]

[0006] To solve the above problems, this invention proposes the following means. A fixture system according to a first aspect of the present invention comprises a structure having an opposing surface that extends vertically and faces one side in the left-right direction perpendicular to the front-rear direction, and a first fixture positioned adjacent to the opposing surface on one side in the left-right direction relative to the structure and movable relative to the structure, wherein the first fixture has a first side wall forming a first side surface facing the opposing surface in the left-right direction, a first partition wall extending from the first side surface toward one side in the left-right direction, and a first projection having a first protrusion extending vertically and projecting from the first side wall to the other side in the left-right direction, wherein the structure has a second protrusion having a second protrusion extending vertically and projecting from the opposing surface to one side in the left-right direction, and the first fixture and the structure are positioned such that the first side surface and the opposing surface face each other in the left-right direction, and the first projection and the second projection overlap when viewed from the front-rear direction.

[0007] According to a first aspect of the present invention, a first projection is provided that protrudes from the first side wall of the first fixture to the other side in the left-right direction, and a second projection is provided that protrudes from the opposing surface of the structure to one side in the left-right direction. The first fixture and the structure are arranged adjacent to each other with the first projection and the second projection overlapping when viewed from the front-rear direction, thereby closing the gap between the first fixture and the structure when viewed from the front-rear direction. As a result, a sense of unity as a fixture system can be created. Furthermore, light leakage and other issues when viewed from the front-rear direction are suppressed, and the fixture system can be presented in a good appearance.

[0008] A second aspect of the present invention relates to a furniture system according to the first aspect, wherein the structure has a second side wall forming the opposing surface facing one side in the left-right direction, and a second partition wall extending from the second side wall toward the other side in the left-right direction, and the structure is a second furniture unit that is movable relative to the first furniture unit.

[0009] According to a second aspect of the present invention, since the movable second fixture is provided with a second projection that protrudes from the opposing surface to one side in the left-right direction, the position of the second fixture, which is placed adjacent to the first fixture, can also be adjusted. This makes it easier to adjust the position in which the fixture system is arranged. Furthermore, since the first and second fixtures are lined up without any gaps when viewed from the front or back, a sense of unity can be created as a fixture system, and the appearance of the fixture system can be improved.

[0010] A third aspect of the present invention relates to a furniture system according to the first aspect, wherein the structure has a storage space formed in it that is surrounded by the second protrusion and open to one side in the left-right direction, and the first furniture and the second furniture are arranged with the first protrusion positioned in the storage space.

[0011] According to a third aspect of the present invention, a storage space surrounded by a second protrusion is provided, and when the first and second furniture pieces are placed adjacent to each other, the first protrusion is positioned within the storage space, so that the gap between the first and second furniture pieces is closed when viewed from the front-to-back direction and from above, allowing the furniture system to be neatly arranged. Furthermore, because the first protrusion is positioned within the storage space, in the front-to-back direction the first protrusion is sandwiched between the second protrusions that form the storage space, restricting the relative movement of the first and second furniture pieces in the front-to-back direction. Therefore, the first and second furniture pieces are prevented from shifting relative to their positions, allowing the furniture system to be neatly arranged.

[0012] A furniture system according to a fourth aspect of the present invention is a furniture system according to the third aspect described above, wherein the first projection is provided on the first side surface at a position spaced inward from the outer peripheral edge of the first side wall, and the second projection is provided on the opposing surface at a position spaced inward from the outer peripheral edge of the second side wall.

[0013] According to a fourth aspect of the present invention, the first projection is provided at a position spaced inward from the outer edge of the first side wall, and the second projection is provided at a position spaced inward from the outer edge of the second side wall. This allows the user to grip the outer edges of the first and second side walls when moving the first and second furniture pieces adjacent to each other. This improves the operability when moving the first and second furniture pieces. Furthermore, when moving the first and second furniture pieces close together, it prevents items from getting caught in the portion of the space between the first and second side walls that is located outward from each projection.

[0014] A fifth aspect of the present invention relates to a furniture system according to the third or fourth aspect, wherein the length of the first protrusion protruding from the first side wall in the left-right direction is less than or equal to the length of the second protrusion protruding from the second side wall in the left-right direction.

[0015] According to a fifth aspect of the present invention, since the protruding length of the first protrusion is less than or equal to the protruding length of the second protrusion, when the first protrusion is placed in the storage space, it is easy to fit the entire length of the first protrusion within the storage space. By fitting the entire length of the first protrusion within the storage space, when the first and second fixtures are brought close together to a position where the second protrusion abuts the first side surface, it is possible to prevent the first protrusion from being exposed between the first and second side walls. Therefore, the fixture system can be arranged in a good appearance.

[0016] A furniture system according to a sixth aspect of the present invention, in the furniture system according to the third or fourth aspect, the second protruding portion has an inclined portion that slopes to one side in the front-rear direction as it extends downward.

[0017] According to the sixth aspect of the present invention, since the second ridge portion has an inclined portion, when an article is dropped from the gap between the first side wall and the second side wall, after the article hits the inclined portion, it is pushed out along the inclined portion to one side in the front-rear direction. Therefore, it is easy to pick up the dropped article from one side in the front-rear direction with respect to the furniture system.

[0018] The furniture system according to the seventh aspect of the present invention is the furniture system according to the third aspect or the fourth aspect, wherein a first hole penetrating the first side wall in the left-right direction is formed in the first side wall, and a second hole penetrating the second side wall in the left-right direction and opening to the accommodation space is formed in the second side wall.

[0019] According to the seventh aspect of the present invention, since it has the first hole and the first hole and the second hole, when wiring or the like is routed between the first furniture and the second furniture, the wiring can be hidden by the first protruding portion and the second protruding portion as viewed from the front-rear direction, and the appearance as a furniture system can be kept in good order.

Effects of the Invention

[0020] According to the present invention, there is provided a furniture system capable of improving the appearance by making it difficult to form a gap between a movable furniture and another structure when the movable furniture is arranged adjacent to the other structure as viewed from the front.

Mode for Carrying Out the Invention

[0022] Hereinafter, the furniture system according to the embodiment will be described with reference to the drawings. In the following description, the same reference numerals are given to configurations having the same or similar functions. And the overlapping descriptions of those configurations may be omitted.

[0023] [Furniture System 100] Referring to FIGS. 1 to 13, the furniture system 100 according to the present embodiment will be described. First, the overall furniture system 100 will be described. However, the furniture system 100 does not necessarily have all the configurations described below, and some configurations may be appropriately omitted.

[0024] In the present embodiment, the direction orthogonal to the installation surface on which the furniture system 100 is installed is defined as the vertical direction Z. Also, when the furniture system 100 is installed, the front side is defined as "front" and the rear side is defined as "rear", and the front-rear direction Y is defined. In the front-rear direction Y, the front is Y1 and the rear is Y2. Note that the front-rear direction Y is orthogonal to the vertical direction Z. Further, the direction orthogonal to the front-rear direction Y and the vertical direction Z is defined as the left-right direction X.

[0025] Figure 1 is a perspective view showing a fixture system 100 according to an embodiment. As shown in Figure 1, the fixture system 100 is a system having multiple movable fixtures, and is a system in which multiple fixtures are used adjacent to each other. The fixture system 100 comprises a movable first movable fixture (first fixture) 10 and a movable second movable fixture (second fixture) 20.

[0026] Figure 2 is a perspective view showing the first mobile fixture 10. Figure 3 is a front view showing the first mobile fixture 10. Figure 4 is a side view showing the first mobile fixture 10.

[0027] The first mobile furniture 10 is a piece of furniture that can be moved relative to the second mobile furniture 20. The first mobile furniture 10 is a piece of furniture that is positioned adjacent to the second mobile furniture 20 in the left-right direction X. In this embodiment, the first mobile furniture 10 is a piece of furniture with a tabletop, such as a lectern. However, the first mobile furniture 10 is not limited to a lectern. The first mobile furniture 10 may be, for example, various pieces of furniture with a tabletop, such as a work desk or a cabinet.

[0028] As shown in Figures 2 to 4, the first mobile fixture 10 includes a first front wall (first partition wall) 11, a first opposing side wall (first side wall) 12, a first non-opposing side wall 13, a top plate 14, a shelf 15, a bottom plate 16, a reinforcing plate 17, and casters 18.

[0029] The first front wall 11 is a member that forms the front surface of the first mobile fixture 10. The first front wall 11 is a plate-shaped member with the front-to-back direction Y as the plate thickness direction. The first front wall 11 extends in the vertical direction Z and the left-to-right direction X. The first front wall 11 is formed in a substantially rectangular shape when viewed from the front-to-back direction Y.

[0030] The first opposing side wall 12 is a member that forms the side surface of the first mobile fixture 10 facing the second side (other side) X2 in the left-right direction X. The first opposing side wall 12 is a member that forms the first side surface 12a (hereinafter referred to as the first opposing side surface 12a) of the side surface of the first mobile fixture 10 that faces the second mobile fixture 20 in the left-right direction X when the fixture system 100 is installed. The first opposing side wall 12 extends rearward Y2 from the end of the second side X2 in the left-right direction X of the first front wall 11. The first opposing side wall 12 is a plate-shaped member with the left-right direction X as the plate thickness direction.

The top plate 14 is connected to the first front wall 11 at a position spaced downward from the upper end of the first front wall 11. The top plate 14 extends in the left-right direction X from the first opposing side wall 12 to the first non-opposing side wall 13. The left-right ends of the top plate 14 in the left-right direction X are connected to the first opposing side wall 12 and the first non-opposing side wall 13, respectively. The top plate 14 is connected to the first opposing side wall 12 and the first non-opposing side wall 13 at a position spaced downward from the upper ends of the first opposing side wall 12 and the first non-opposing side wall 13. In other words, the first front wall 11, the first opposing side wall 12, and the first non-opposing side wall 13 protrude upward from the top surface of the top plate 14. Therefore, items placed on the top surface of the top plate 14 are difficult to see from the front and are unlikely to fall off the top plate 14.

[0034] The shelf board 15 is a component that forms a shelf on the first mobile fixture 10. The shelf board 15 is positioned below the top plate 14. The shelf board 15 has a plate-like shape with the vertical direction Z being the thickness direction.

The base plate 16 extends in the left-right direction X from the lower end of the first opposing side wall 12 to the lower end of the first non-opposing side wall 13. The left-right ends of the base plate 16 in the left-right direction X are connected to the lower end of the first opposing side wall 12 and the end of the first non-opposing side wall 13, respectively.

[0036] The reinforcing plate 17 is a member that reinforces the lower part of the first mobile fixture 10. The reinforcing plate 17 is, for example, plate-shaped with the front-to-back direction Y as the plate thickness direction. The reinforcing plate 17 extends in the left-to-right direction X from the first opposing side wall 12 to the first non-opposing side wall 13. The left-to-right ends of the reinforcing plate 17 connect the first opposing side wall 12 to the first non-opposing side wall 13, respectively. The front end Y1 of the reinforcing plate 17 is connected to the first front wall 11. The mechanical strength of the first mobile fixture 10 is improved by the provision of the reinforcing plate 17.

[0037] The caster 18 has a wheel that can, for example, pivot around an axis along the vertical direction Z and rotate in a direction perpendicular to the vertical direction Z. Four casters 18 are provided at the lower end of the base plate 16.

The shape of the inclined portion 42a is not limited. Furthermore, the inclined portion 42a may not be formed at all. Moreover, the entire second rear projection 42 may be provided at a position spaced forward Y1 from the rear end of the second opposing side wall 22.

[0056] The second upper projection 43 is a member that protrudes from the second opposing side wall 22 to the first side X1 in the left-right direction X. The second upper projection 43 is a member that extends in the front-rear direction Y. The second upper projection 43 is a member that extends from the upper end of the second front projection 41 to the upper end of the second rear projection 42 (upper straight section 42s). The second upper projection 43 is provided on the upper part of the second opposing side wall 22. Specifically, the second upper projection 43 is provided at a position spaced downward from the upper end of the second opposing side wall 22.

[0057] The shapes of the first protrusion 3 and the second protrusion 4 are not limited. The first protrusion 3 and the second protrusion 4 only need to have a ridge extending in the vertical direction Z. That is, the first protrusion 3 and the second protrusion 4 may have, for example, only one ridge extending in the vertical direction Z. Also, the ridge extending in the vertical direction only needs to have at least a component that extends in the vertical direction. In this case, the ridge may be circular or arc-shaped when viewed from the left-right direction X.

[0058] The second mobile fixture 20 has a storage space 4a formed in which the second opposing side wall 22 and the second protrusion 4 are enclosed. Specifically, the storage space 4a is enclosed by the second opposing side wall 22, the second front protrusion 41, the second rear protrusion 42, and the second upper protrusion 43, and is open to the first side X1 in the left-right direction X. The storage space 4a is formed to a size that can accommodate the first protrusion 3 when viewed from the left-right direction X. The storage space 4a is formed in a position that can accommodate the first protrusion 3 when viewed from the left-right direction X. The first mobile fixture 10 and the second mobile fixture 20 are arranged with the first protrusion 3 positioned in the storage space 4a. That is, when the first mobile fixture 10 and the second mobile fixture 20 are arranged facing each other in the left-right direction X, the first protrusion 3 is positioned inward from the second protrusion 4.

[0059] In the second projection 4, the second front projection 41 is provided at a position spaced rearward Y2 from the front end of the second opposing side wall 22, the second rear projection 42 is provided at a position spaced forward Y1 from the rear end of the second opposing side wall 22, and the second upper projection 43 is provided at a position spaced downward from the upper end of the second opposing side wall 22. In other words, the second projection 4 is provided at a position spaced inward from the outer peripheral edge of the second opposing side wall 22. Therefore, the part of the second opposing side wall 22 that is more peripheral than the second projection 4 is used as a handle portion 22b that can be gripped.

[0060] The length L1 of the first protrusion 3 protruding from the first opposing side wall 12 in the left-right direction X (length of the first protrusion 3) is approximately equal to the length L2 of the second protrusion 4 protruding in the left-right direction X (length of the second protrusion 4). It is preferable that the length L1 of the first protrusion 3 and the length L2 of the second protrusion 4 are greater than the thickness of the user's hand. That is, it is preferable that the length L1 of the first protrusion 3 and the length L2 of the second protrusion 4 are 20 mm or more. However, the length L1 of the first protrusion 3 may be less than or equal to the length of the second protrusion 4. It is preferable that the length L1 of the first protrusion 3 is smaller than the length L2 of the second protrusion 4.

[0061] [First hole 5 and second hole 6] As shown in Figures 2 and 4, a first hole 5 is formed in the first opposing side wall 12 of the first mobile fixture 10, penetrating the first opposing side wall 12. As shown in Figures 5 and 7, a second hole 6 is formed in the second opposing side wall 22 of the second mobile fixture 20, penetrating the second opposing side wall 22.

[0062] The first hole 5 is formed on the inside of the first projection 3 of the first opposing side wall 12 (the portion surrounded by the first projection 3 when viewed from the left-right direction X). The first hole 5 is formed at the front Y1 of the first opposing side wall 12 surrounded by the first projection 3. The first hole 5 penetrates the first opposing side wall 12 in the left-right direction X. The internal space of the first mobile furniture 10 (the space below the top plate 14 of the first mobile furniture 10 (lower limb space)) is in communication with the external space of the first mobile furniture 10 in the left-right direction X. The first hole 5 is formed in a substantially rectangular shape when viewed from the left-right direction X.

[0063] The second hole 6 is formed on the inside of the second protrusion 4 of the second opposing side wall 22 (the portion surrounded by the second protrusion 4 when viewed from the left-right direction X). That is, the second hole 6 is open to the storage space 4a. The second hole 6 is formed at the front Y1 of the second opposing side wall 22 surrounded by the second protrusion 4. The second hole 6 penetrates the second opposing side wall 22 in the left-right direction X. The internal space of the second mobile furniture 20 (the space below the top plate 24 of the second mobile furniture 20 (lower limb space)) is in communication with the external space of the second mobile furniture 20 in the left-right direction X. The second hole 6 is formed in a substantially rectangular shape when viewed from the left-right direction X.

[0064] The second hole 6 is formed in a position opposite the first hole 5 in the left-right direction X when the first mobile fixture 10 and the second mobile fixture 20 are arranged facing each other in the left-right direction X. The first hole 5 and the second hole 6 function as wiring insertion holes for routing wiring between the first mobile fixture 10 and the second mobile fixture 20. In other words, the fixture system 100 is configured so that wiring can be routed between the internal space of the first mobile fixture 10 and the internal space of the second mobile fixture 20 through the inside of the first protrusion 3 and the second protrusion 4.

[0065] [Function of fixture system 100] Next, the operation of the fixture system 100 will be explained with reference to Figures 8 to 11. Figure 8 is a perspective view showing the opposing portions of the first mobile fixture 10 and the second mobile fixture 20. Figure 9 is a front view showing the opposing portions of the first mobile fixture 10 and the second mobile fixture 20. Figure 10 is a side view showing the opposing portions of the first mobile fixture 10 and the second mobile fixture 20. Figure 11 is a cross-sectional view along the line F11-F11 of the opposing portions of the first mobile fixture 10 and the second mobile fixture 20 shown in Figure 9.

[0066] Since the first mobile fixture 10 and the second mobile fixture 20 are both movable, the fixture system 100 can be moved to any location when not in use. Furthermore, since the fixture system 100 can be separated into the first mobile fixture 10 and the second mobile fixture 20, it can be transformed and arranged in a form that is easy to place in any location. In addition, since the first mobile fixture 10 and the second mobile fixture 20 are both movable, the fixture system 100 is easy to move when needed.

[0067] When the fixture system 100 is used, the first mobile fixture 10 and the second mobile fixture 20 are positioned so that the first opposing side wall 12 of the first mobile fixture 10 and the second opposing side wall 22 of the second mobile fixture 20 face each other in the left-right direction X, as shown in Figure 1. Then, as shown in Figures 8 to 10, the first mobile fixture 10 and the second mobile fixture 20 are moved relative to each other so that the first protrusion 3 is housed in the storage space 4a. In this case, for example, the first mobile fixture 10 is moved with hands on its side walls 12 and 13, and the second mobile fixture 20 is moved with hands on its side walls 22 and 23. In particular, regarding the opposing side walls 12 and 22 of each mobile fixture 10 and 20, operability can be ensured even if the distance between each mobile fixture 10 and 20 is reduced, by placing hands on the handles 12b and 22b.

[0068] When the movable fixtures 10 and 20 are brought close together until the first protrusion 3 is housed in the storage space 4a, the first protrusion 3 and the second protrusion 4 overlap. Specifically, the first front projection 31 and the second front projection 41, and the first rear projection 32 and the second rear projection 42 overlap when viewed from the front-to-back direction Y, and the first upper projection 33 and the second upper projection 43 overlap when viewed from the up-to-down direction Z. As a result, as shown in Figures 8 and 9, the gap between the first movable fixture 10 and the second movable fixture 20 is closed when viewed from the front-to-back direction Y and the up-to-down direction Z.

[0069] In the fixture system 100, it is preferable to bring the movable fixtures 10 and 20 close together until the second protrusion 4 abuts against the first opposing side surface 12a. This ensures that the first protrusion 3, which is housed in the storage space 4a, is covered from the outside by the second protrusion 4 along its entire length in the left-right direction X. Therefore, only the second protrusion 4 is exposed between the first opposing side wall 12 and the second opposing side wall 22 (the first protrusion 3 is not exposed), thus creating a sense of unity for the fixture system 100. However, the fixture system 100 may also be configured such that the first protrusion 3 is close to the second opposing side surface 22a and the second protrusion 4 is close to the first opposing side surface 12a.

[0070] The display unit system 100 is used with the audience gathered in front of it Y1 and the speaker standing behind it Y2. Therefore, the audience views the display unit system 100 from the front Y1. In this case, the gap between the first movable display unit 10 and the second movable display unit 20 is closed by the first protrusion 3 and the second protrusion 4, which suppresses light leakage when viewed from the front-to-back direction Y, and allows the display unit system 100 to be neatly arranged.

[0071] For example, let's consider the case where a speaker drops an object (such as a pen) between the first mobile fixture 10 and the second mobile fixture 20. If the object lands on the second upper protrusion 43 between the first mobile fixture 10 and the second mobile fixture 20, it may be difficult to reach in with a hand or other object between the two fixtures to pick up the object. In this case, the object that has landed on the second upper protrusion 43 can be pushed out from behind the second upper protrusion 43 by sliding it backward from the second upper protrusion 43. The object will then fall from the second upper protrusion 43 and collide with the inclined section 42a. The object that has collided with the inclined section 42a will be guided backward as it moves downward following the inclined section 42a. As a result, the items move from the rear of the fixture system 100 on the installation surface to a position within reach of a hand or similar object (a position near the rear or rear end of the fixture system 100). Therefore, the items can be picked up without moving each of the mobile fixtures 10, 20.

[0072] Furthermore, when wiring is to be stretched between the lower limb space of the first mobile furniture 10 and the lower limb space of the second mobile furniture 20, the wiring is passed through the first hole 5 and the second hole 6. That is, the wiring can be pulled out from the lower limb space of the first mobile furniture 10 through the first hole 5 to the external space of the first mobile furniture 10 (the external space of the second mobile furniture 20), and pulled in through the second hole 6 to the lower limb space of the second mobile furniture 20. In this case, the first hole 5 and the second hole 6 are open on the inner side of the protrusions 3 and 4 in the respective opposing side walls 12 and 22. Therefore, the wiring is stretched between the lower limb space of the first mobile furniture 10 and the lower limb space of the second mobile furniture 20 while being hidden by the first protrusion 3 and the second protrusion 4.

[0073] According to the fixture system 100 of this embodiment, a first projection 3 is provided that protrudes from the first opposing side wall 12 of the first mobile fixture (first fixture) 10 to the second side (other side) X2 in the left-right direction X, and a second projection 4 is provided that protrudes from the opposing surface 22a of the second mobile fixture (structure) 20 to the first side (one side) in the left-right direction X. The first mobile fixture (first fixture) 10 and the second mobile fixture (structure) 20 are arranged adjacent to each other with the first projection 3 and the second projection 4 overlapping when viewed from the front-rear direction Y, so that the gap between the first mobile fixture (first fixture) 10 and the second mobile fixture (structure) 20 is closed when viewed from the front-rear direction Y. As a result, a sense of unity as a fixture system 100 can be created. Furthermore, light leakage and other issues when viewed from the front-rear direction Y are suppressed, and the fixture system 100 can be presented in a good appearance.

[0074] According to the fixture system 100 of this embodiment, the movable second mobile fixture (second fixture) 20 is provided with a second projection 4 that protrudes from the opposing surface 22a to the first side (one side) in the left-right direction X. Therefore, the position of the second mobile fixture (second fixture) 20, which is placed adjacent to the first mobile fixture (first fixture) 10, can also be adjusted. This makes it easy to adjust the position in which the fixture system 100 is placed. In addition, when viewed from the front-rear direction Y, the first mobile fixture (first fixture) 10 and the second mobile fixture (second fixture) 20 are lined up without any gaps being formed between them, so a sense of unity can be created for the fixture system 100, and the appearance of the fixture system 100 can be well-maintained.

[0075] According to the fixture system 100 of this embodiment, a storage space 4a surrounded by the second protrusion 4 is provided, and when the first mobile fixture (first fixture) 10 and the second mobile fixture (second fixture) 20 are placed adjacent to each other, the first protrusion 3 is positioned in the storage space 4a, so that the gap between the first mobile fixture (first fixture) 10 and the second mobile fixture (second fixture) 20 is closed when viewed from the front-rear direction Y and from above, and the fixture system 100 can be neatly arranged. Furthermore, because the first protrusion 3 is positioned in the storage space 4a, in the front-rear direction Y the first protrusion 3 is sandwiched between the second protrusion 4 that form the storage space 4a, and the relative movement of the first mobile fixture (first fixture) 10 and the second mobile fixture (second fixture) 20 in the front-rear direction Y is restricted. Therefore, the first mobile fixture (first fixture) 10 and the second mobile fixture (second fixture) 20 are prevented from shifting relative to their respective positions, and the fixture system 100 can be arranged in a good manner.

[0076] According to the fixture system 100 of this embodiment, the first projection 3 is provided at a position spaced inward from the outer circumference of the first opposing side wall 12, and the second projection 4 is provided at a position spaced inward from the outer circumference of the second opposing side wall 22. Therefore, when the first movable fixture (first fixture) 10 and the second movable fixture (second fixture) 20 are placed adjacent to each other, it is possible to place hands on the outer edges of the first opposing side wall 12 and the second opposing side wall 22. As a result, when the first movable fixture (first fixture) 10 and the second movable fixture (second fixture) 20 are brought close together, it is possible to prevent items from getting caught in the portion of the space between the first opposing side wall 12 and the second opposing side wall 22 that is located outward from each projection.

[0077] According to the fixture system 100 of this embodiment, the protruding length of the first protrusion 3 is less than or equal to the protruding length of the second protrusion 4. Therefore, when the first protrusion 3 is placed in the storage space 4a, it is easy to fit the entire length of the first protrusion 3 into the storage space 4a. By fitting the entire length of the first protrusion 3 into the storage space 4a, when the first movable fixture (first fixture) 10 and the second movable fixture (second fixture) 20 are brought close together to a position where the second protrusion 4 abuts the first opposing side surface 12a, it is possible to suppress the exposure of the first protrusion 3 between the first opposing side wall 12 and the second opposing side wall 22. Therefore, the fixture system 100 can be assembled in a good-looking manner.

[0078] According to the fixture system 100 of this embodiment, since the second rear projection (second projection) 42 has an inclined portion 42a, when an item is dropped through the gap between the first opposing side wall 12 and the second opposing side wall 22, the item hits the inclined portion 42a and is then pushed along the inclined portion 42a to one side in the front-rear direction Y. Therefore, it is easy to pick up the dropped item from one side relative to the fixture system 100.

[0079] According to the fixture system 100 of this embodiment, since it has a first hole 5 and a second hole 6 that is positioned opposite the first hole 5 in the left-right direction X, when routing wiring etc. between the first mobile fixture (first fixture) 10 and the second mobile fixture (second fixture) 20, the wiring etc. can be hidden by the first protrusion 3 and the second protrusion 4 when viewed from the front-rear direction Y, and the fixture system 100 can be given a good appearance.

[0080] (modified version) Next, a modified example of the fixture system 100B will be described with reference to Figures 12 and 13.

[0081] Figure 12 is a side view showing a modified first mobile fixture 10B. Figure 13 is a side view showing a modified second mobile fixture 20B.

[0082] The fixture system 100B is a modified version of the fixture system 100. The shape of the protruding part of the fixture system 100B differs from that of the fixture system 100.

[0083] The fixture system 100B includes a first mobile fixture 10B and a second mobile fixture 20B. The first mobile fixture 10B has a first protrusion 3B, which is a modified example of the first protrusion 3, as shown in Figure 12. The second mobile fixture 20B has a second protrusion 4B, which is a modified example of the second protrusion 4, as shown in Figure 13.

[0084] The first upper projection 33B of the first projection 3B has an inclined portion 33Ba, as shown in Figure 12. The inclined portion 33Ba is inclined downward as it moves backward Y2. The inclined portion 33Ba is formed, for example, along the entire length of the first upper projection 33B (from the front end to the rear end). The second upper projection 43B of the second projection 4B has an inclined portion 43Ba, as shown in Figure 13. The inclined portion 43Ba is inclined downward as it moves backward Y2. The inclined portion 43Ba is formed, for example, from the front end to the rear end of the second upper projection 43B.

[0085] Because inclinations are formed on the first upper protrusion 33B of the first protrusion 3B and the second upper protrusion 43B of the second protrusion 4B, when an object is dropped from above the first protrusion 3B and the second protrusion 4B, the object hits the inclination and is pushed outwards from the first opposing side wall 12 and the second opposing side wall 22, making it easy to pick up the dropped object.

[0086] Although embodiments of the present invention have been described in detail above with reference to the drawings, the specific configuration is not limited to these embodiments, and design modifications and the like are also included within the scope of the gist of the present invention. Furthermore, the components shown in the above embodiments can be combined as appropriate.

[0087] The fixture system 100 may have a structure having an opposing surface 22a as a substitute for the second mobile fixture 20. The opposing surface 22a is the surface that faces the first mobile fixture 10 in the left-right direction X when the fixture system 100 is installed. The structure that substitutes for the second mobile fixture 20 may be movable or immovable. An immovable structure may be a structure other than a fixture (for example, a wall). In other words, the fixture system 100 only needs to have the first mobile fixture 10 movable relative to the second mobile fixture 20.

[0088] The fixture system 100 may have three or more movable fixtures. In this case, the multiple movable fixtures are arranged adjacent to each other in the left-right direction X. In this case, it is preferable that the fixture located in the center of the three adjacent fixtures has protrusions on both side walls in the left-right direction X.

[0089] The first mobile fixture 10 may be a lifting fixture in which the top plate 14 is provided to be movable in the vertical direction Z. The second mobile fixture 20 may be a lifting fixture in which the top plate 24 is provided to be movable in the vertical direction Z.

[0090] The first front wall (first partition wall) 11 and the second front wall (second partition wall) 21 form the front surfaces of the first mobile fixture 10 and the second mobile fixture 20, but the positions in which the first and second partition walls are provided are not limited. For example, the first front wall 11 may form the rear surface of the first mobile fixture 10, or it may be formed in the central part of the first mobile fixture 10 in the front-to-back direction Y.

[0091] The first front wall (first partition wall) 11 and the second front wall (second partition wall) 21 do not necessarily have to be formed along the entire length in the vertical direction Z of the first mobile fixture 10 (side walls 12, 13) and the second mobile fixture 20 (side walls 22, 23). For example, the first front wall 11 only needs to be provided on at least a portion of the first mobile fixture 10 (side walls 12, 13) in the vertical direction Z.

[0092] The first projection 3 may be provided along the outer peripheral edge of the first opposing side wall 12. The second projection 4 may be provided along the outer peripheral edge of the second opposing side wall 22.

[0093] A cushioning material may be provided on the tip surface of the first protrusion 3. The cushioning material may be made of rubber, for example, and only needs to be provided on at least a portion of the tip surface of the first protrusion 3. By providing a cushioning material on the tip surface of the first protrusion 3, the impact when the tip of the first protrusion 3 comes into contact with the second movable fixture 20 can be mitigated.

[0094] A cushioning material may be provided on the tip surface of the second protrusion 4. The cushioning material is made of, for example, rubber and is applied to the entire tip surface of the second protrusion 4. By providing a cushioning material on the tip surface of the second protrusion 4, the tip of the second protrusion 4 is less likely to be damaged when it comes into contact with the first movable fixture 10.

[0095] In this embodiment, an inclined portion 42a is formed on the second rear projection 42, but an inclined portion may also be formed on the second front projection 41. The inclined portion formed on the second front projection 41, for example, inclins forward Y1 as it extends downward.

[0096] The first protrusion 3 may be detachably attached to the first opposing side wall 12. Furthermore, the first protrusion 3 detachably attached to the first opposing side wall 12 may be detachably attached to the side walls of the first mobile fixture 10 other than the first opposing side wall 12. In other words, the first protrusion 3 may be configured to be interchangeable with multiple side walls. For example, the first protrusion 3 may be detachably attached to the first opposing side wall 12 and the first non-opposing side wall 13. Furthermore, the first protrusion 3 detachably attached to the first opposing side wall 12 may be detachably attached to the side wall of the second mobile fixture 20. In other words, the first protrusion 3 may be configured to be interchangeable with the side wall of the second mobile fixture 20. For example, the first protrusion 3 may be detachably attached to the first opposing side wall 12 and the second opposing side wall 22. The second protrusion 4, like the first protrusion 3, may be detachably attached to multiple side walls of the first mobile fixture 10 and the second mobile fixture 20. By providing the first protrusion 3 and the second protrusion 4 detachably, the first mobile fixture 10 and the second mobile fixture 20 can be positioned in a location convenient for the user.

[0097] In this embodiment, a configuration has been described in which a storage space 4a surrounded by the second protrusion 4 is formed in the second mobile fixture 20, but the configuration is not limited to this. A storage space may be formed in the first protrusion 3, and the second protrusion 4 may be arranged inside the first protrusion 3. [Explanation of Symbols]
