Summary of the Invention

Problems to be Solved by the Invention

[0004] However, since the furniture with a top plate is tilted with respect to the horizontal plane during movement, when placing an article on the furniture with a top plate, for example, it is necessary to firmly fix it to the furniture with a top plate so that the article remains stable even when tilted during movement. However, there is a problem that it takes time and effort to remove it if it is firmly fixed. Further, when the article is once removed during movement without firmly fixing it, there is a problem that it is inconvenient because it is necessary to bring the article again and place it after movement.

[0005] Therefore, the present invention has been made in view of the above circumstances, and provides a furniture with a top plate capable of suppressing the fall of an article when tilted and moved. [Means for solving the problem]

[0006] To achieve the above objective, the present invention employs the following means. In other words, the fixture with a top plate according to the present invention comprises a lower structure installed on the floor surface, an upper structure supported by the lower structure and having a top plate, and an engaging body provided on at least one of the lower structure and the upper structure, wherein the lower structure has a first leg portion provided with a first caster that can travel on the floor surface, a second leg portion provided with a second caster that can travel on the floor surface and is spaced apart from the first leg portion in a first direction, and a third leg portion provided with a second caster that can travel on the floor surface and is spaced apart from the first leg portion on one side in a second direction different from the first direction, and is not provided with a caster that can travel on the floor surface, and the engaging body has a regulating surface portion facing one side in the second direction, and an engaging surface portion extending upward from the lower part of the regulating surface portion to one side in the second direction.

[0007] In a fixture with a top plate configured in this way, when moving the fixture with a top plate, the top plate is lifted so that one side in the second direction is upward, and the fixture is moved by running it on the floor surface using the first casters and second casters provided on the other side in the second direction. Articles engaged with the engaging surface of the engaging body will attempt to move to the other side in the second direction due to their own weight, but this movement is restricted by the restricting surface. Therefore, when moving the fixture with a top plate at an angle, it is possible to prevent articles from falling from the engaging body.

[0008] Furthermore, in the fixture with a top plate according to the present invention, the engaging body is a hook attached to the lower part of the top plate, and a gap may be formed in the vertical direction between the engaging surface of the hook and the lower part of the top plate.

[0009] In a fixture with a tabletop configured in this way, the engaging element is a hook, so the hook can be easily attached to the underside of the tabletop.

[0010] Furthermore, in the fixture with a top plate according to the present invention, a gap may be formed in the vertical direction between the engaging surface and the lower part of the top plate.

[0011] In a fixture with a top plate configured in this way, a gap is formed in the vertical direction between the engaging surface and the lower part of the top plate. Therefore, an item can be passed through the gap between the engaging surface and the lower part of the top plate and engaged with the engaging surface.

[0012] Furthermore, in the fixture with a top plate according to the present invention, the engaging body may be provided at one end of the top plate in the second direction.

[0013] In this configuration of a fixture with a tabletop, the engaging body is provided at one end of the tabletop in the second direction. Therefore, items can be engaged with the engaging surface from one end of the tabletop in the second direction, thereby increasing convenience. When a user stands on one side of the fixture with a tabletop in the second direction and lifts and moves the tabletop, they are more likely to notice items placed on the engaging body, thus preventing them from forgetting items after their last use.

[0014] Furthermore, in the fixture with a top plate according to the present invention, the engaging body may be provided at the center of the top plate in the first direction.

[0015] In this configuration of a fixture with a tabletop, the engaging body is located in the center of the tabletop in the first direction. Therefore, when a user stands on one side of the fixture in the second direction and lifts the tabletop with both hands to move it, the weight of the items attached to the engaging body is evenly distributed across both hands, allowing the fixture to be moved in a balanced manner.

[0016] Furthermore, in the fixture with a top plate according to the present invention, the engaging body may be arranged to overlap the top plate in a plan view.

[0017] In this configuration of a fixture with a top panel, the engaging body is positioned overlapping the top panel in a plan view. Therefore, the engaging body does not protrude from the top panel, and thus does not get in the way of users of the fixture with a top panel. Furthermore, even when multiple fixtures with top panels are arranged so that their top panels are adjacent to each other, the engaging bodies do not come into contact with each other, thus preventing damage to the engaging bodies.

[0018] Furthermore, in the fixture with a tabletop according to the present invention, the lower structure may have a fourth leg portion that is spaced apart from the second leg portion on one side in the second direction and does not have casters that can move on the floor surface.

[0019] In a fixture with a tabletop configured in this way, the tabletop can be stably supported by four legs: a first leg equipped with a first caster, a second leg equipped with a second caster, a third leg without a caster, and a fourth leg without a caster.

[0020] Furthermore, the fixture with a top plate according to the present invention may be provided with a display mounting section on the top plate directly above the engaging body, on which a display can be installed.

[0021] In this configuration of a tabletop-mounted furniture unit, a display mounting section is provided directly above the engaging body on the tabletop, where a display can be installed. By hooking a bag containing a battery onto the engaging body, the distance between the battery and the display is shortened, allowing for easy power supply from the battery to the display. Furthermore, because the power supply cable is shorter, it does not get in the way when moving the tabletop-mounted furniture unit. In addition, during long exercises where team formations are changed frequently, the tabletop-mounted furniture unit may be moved often, but even when commercial power is unavailable, the display can be used for extended periods.

[0022] Furthermore, in the fixture with a tabletop according to the present invention, the engaging body and the display mounting part may be fixed integrally to the tabletop.

[0023] In the furniture with a top plate configured as described above, the engaging body and the display installation part are integrally fixed to the top plate. Therefore, the fixed parts of the engaging body and the display installation part can be stored more compactly than in the case where the fixed parts are separate.

Effect of the Invention

[0024] According to the furniture with a top plate according to the present invention, when moving while tilted, it is possible to suppress the fall of the article.

The restricting wall portion 32 extends in the vertical direction. A pair of restricting wall portions 32 are provided spaced apart in the first direction X. The restricting wall portion 32 may also extend downward from the middle portion of the mounting wall portion 31 in the second direction Y.

[0039] The restricting wall portion 32 has a restricting surface portion 32a. The restricting surface portion 32a is a surface facing one side Y1 of the second direction Y. The restricting surface portion 32a is arranged along the vertical direction. The restricting surface portion 32a may be inclined with respect to the vertical plane as long as it faces one side Y1 of the second direction Y. The restricting surface portion 32a may gradually extend toward one side Y1 or the other side Y2 of the second direction Y as it extends upward. The restricting surface portion 32a may gradually extend toward one side Y1 or the other side Y2 of the second direction Y as it extends toward one side of the first direction X. The restricting surface portion 32a may be formed in a curved shape.

[0040] The engaging wall portion 33 extends from the lower end of the restricting wall portion 32 to one side Y1 in the second direction Y. The engaging wall portions 33 are provided in pairs, spaced apart in the first direction X.

[0041] The engaging wall portion 33 has an engaging surface portion 33a. The engaging surface portion 33a is an upward-facing surface. The engaging surface portion 33a is arranged along the second direction Y. The engaging surface portion 33a may be inclined with respect to the horizontal plane as long as it faces upward. The engaging surface portion 33a may extend gradually upward or downward as it moves toward one side Y1 of the second direction Y. The regulating surface portion 32a may extend gradually upward or downward as it moves toward one side of the first direction X. The engaging surface portion 33a may be formed in a curved shape.

[0042] An inclined wall portion 34 is provided at one end Y1 in the second direction Y of the engaging wall portion 33. The inclined wall portions 34 are provided in pairs, spaced apart in the first direction X. The inclined wall portions 34 are inclined with respect to the horizontal plane so as they gradually move upward towards one side Y1 in the second direction Y. Note that an inclined wall portion 34 is not required at one end Y1 in the second direction Y of the engaging wall portion 33.

[0043] A vertical gap S1 is formed between the tip 34a of the inclined wall portion 34 and the lower surface 20d of the top plate 20. The engaged portion b2 of the article, described later, can be inserted through the gap S and hooked onto the hook 3. A vertical gap S2 is formed between the engaging surface 33a of the engaging wall portion 33 and the lower surface 20d of the top plate 20. The gap S2 is in communication with the gap S1. The engaged portion b2 can be placed in the gap S2.

[0044] The tip portions 34a of a pair of inclined wall portions 34 are connected by a connecting wall portion 35 that extends in the first direction X.

[0045] The tip 34a of the inclined wall portion 34, which corresponds to the end of one side Y1 in the second direction Y of the hook 3, is located directly below the end 20a of one side Y1 in the second direction Y of the top plate 20, or on the other side Y2 in the second direction Y beyond the end 20a. In plan view, the outer edge of the hook 3 is positioned overlapping the top plate 20. However, in plan view, the outer edge of the hook 3 may extend outward from the top plate 20.

[0046] As shown by the dashed line in Figure 2, an annular engaging portion b2, such as a string or band, provided on the bag body b1 can be engaged with the hook 3. The engaging portion b2 is engaged with the engaging surface portion 33a of the engaging wall portion 33. The bag body b1 can store items such as batteries. In addition to the annular engaging portion b2, S-shaped or O-shaped hook members can also be engaged with the hook 3.

[0047] (Display mounting components) As shown in Figure 1, the display mounting member 4 is fixed to the top of the top plate 20. The display mounting member 4 is fixed approximately in the center of the top plate 20 in the first direction X. The display mounting member 4 is fixed to one end Y1 of the top plate 20 in the second direction Y.

[0048] As shown in Figure 4, the display mounting member 4 has a fixing part 40 and a mounting part 45.

[0049] The fixing portion 40 includes a mounting wall portion 41, upper and lower wall portions 42, a bent wall portion 43, and a support wall portion 44. The mounting wall portion 41, upper and lower wall portions 42, bent wall portion 43, and support wall portion 44 are integrally constructed.

[0050] The mounting wall portion 41 is positioned along the lower surface 20d of the top plate 20, and is in contact with the lower surface 20d. The mounting wall portion 41 extends in the second direction Y. The mounting wall portion 41 is positioned directly above the mounting wall portion 31 of the hook 3.

[0051] A cover portion 46 is provided on the mounting wall portion 41. The cover portion 46 has a first cover wall portion 46a, a second cover wall portion 46b, and a third cover wall portion 46c (see Figure 2).

[0052] The first cover wall portion 46a extends downward from the mounting wall portion 41. The first cover wall portion 46a is positioned on one side Y1 in the second direction Y of the mounting wall portion 31 of the hook 3. The first cover wall portion 46a covers the mounting wall portion 31 of the hook 3 from one side Y1 in the second direction Y.

[0053] The second cover wall portion 46b extends from the lower end of the first cover wall portion 46a to the other side Y2 in the second direction Y. The second cover wall portion 46b is located below the mounting wall portion 31 of the hook 3. The second cover wall portion 46b covers the mounting wall portion 31 of the hook 3 from below.

[0054] The screw 47 is inserted through the mounting hole formed in the second cover wall portion 46b, the mounting hole formed in the mounting wall portion 31 of the hook 3, and the mounting hole formed in the mounting wall portion 41 of the display mounting member 4, and is screwed into the screw hole formed in the lower part of the top plate 20. The hook 3 and the display mounting member 4 are fixed together to the top plate 20 by fastening them together with the screw 47.

[0055] As shown in Figure 2, the third cover wall portion 46c extends upward from both ends of the second cover wall portion 46b in the first direction X. The third cover wall portion 46c covers both sides of the mounting wall portion 31 in the first direction X.

[0056] As shown in Figure 4, the upper and lower wall portions 42 extend upward from one end Y1 in the second direction Y of the mounting wall portion 41. The upper and lower wall portions 42 are positioned along the end 20a of the top plate 20. The upper and lower wall portions 42 extend above the top plate 20.

[0057] The bent wall portion 43 extends from the upper end of the upper and lower wall portions 42 to the other side Y2 in the second direction Y. The bent wall portion 43 extends gradually upward as it moves towards the other side Y2 in the second direction Y.

[0058] The support wall portion 44 extends from the upper end of the bent wall portion 43 to one side Y1 in the second direction Y. The support wall portion 44 extends gradually upward as it moves towards one side Y1 in the second direction Y.

[0059] The mounting section 45 has a fixing plate section 48 and a mounting plate section 49. The fixing plate section 48 and the mounting plate section 49 are integrally constructed.

[0060] The fixing plate portion 48 is formed in a flat plate shape. The fixing plate portion 48 extends gradually upward as it moves toward one side Y1 in the second direction Y. The fixing plate portion 48 is fixed to the other side Y2 in the second direction Y of the support wall portion 44.

[0061] The mounting plate portion 49 extends from the lower end of the fixing plate portion 48 to the other side Y2 in the second direction Y. The mounting plate portion 49 extends gradually upward as it moves towards the other side Y2 in the second direction Y. A retaining wall portion 49a is provided at the tip of the mounting plate portion 49. The retaining wall portion 49a extends gradually to one side in the second direction Y as it moves upward from the end of the mounting plate portion 49 on the other side Y2 in the second direction Y.

[0062] The display D is placed along the other side Y2 in the second direction Y of the fixing plate portion 48 of the display mounting member 4. The lower end of the display D is supported by the mounting plate portion 49 of the display mounting member 4. A retaining wall portion 49a is positioned on the front of the display D. The rear surface of the display D may be fixed to the fixing plate portion 48 by adhesive material, double-sided tape, or the like.

[0063] A display mounting member 4 is positioned directly above the hook 3. In a plan view, the hook 3 overlaps the display mounting member 4. In a plan view, it is preferable that at least a portion of the hook 3 overlaps the display mounting member 4. However, in a plan view, the hook 3 does not necessarily have to overlap the display mounting member 4.

[0064] If you lift the desk 100 by holding one side Y1 in the second direction Y of the tabletop 20, for example, the adjusters 13 of the legs 10C and 10D will lift off the floor surface F. Since the casters 12 of the legs 10A and 10B are in contact with the floor surface F, the desk 100 can be moved by the rolling of the casters 12.

[0065] As shown in Figure 3, when one side Y1 in the second direction Y of the tabletop 20 of the desk 100 is raised upward, the engaged portion b2 is positioned at the corner between the restricting surface portion 32a and the engaging surface portion 33a of the hook 3. The upper part of the engaged portion b2 attempts to move toward the restricting wall portion 32 due to the weight of the items stored in the bag b1, but its movement is restricted when it hits the restricting surface portion 32a. Furthermore, it cannot slip out through the gap S1 formed between the tabletop 20 and the hook 3.

[0066] In the desk 100 configured in this way, when moving the desk 100, the tabletop 20 is lifted so that one side Y1 in the second direction Y is upward, and the desk is moved by running it on the floor surface F using the casters 12 of the legs 10A and 10B provided on the other side Y2 in the second direction Y. An item engaged with the engaging surface 33a of the hook 3 will try to move to the other side Y2 in the second direction Y due to its own weight, but the restricting surface 32a restricts its movement to the other side Y2 in the second direction Y. Therefore, when tilting the desk 100 to move it, it is possible to prevent items from falling from the hook 3.

[0067] Furthermore, since the engaging body is a hook 3, the hook 3 can be easily attached to the lower part of the top plate 20.

[0068] Furthermore, a gap S1 is formed in the vertical direction between the tip 34a of the inclined wall portion 34 of the hook 3 and the lower surface 20d of the top plate 20. Therefore, the engaged portion b2 can be passed through the gap S1 and engaged with the engaging surface portion 33a.

[0069] Furthermore, the hook 3 is provided at the end 20a of one side Y1 in the second direction Y of the tabletop 20. Therefore, items can be engaged with the engagement surface 33a from the end 20a side of the tabletop 20, thereby increasing convenience. When a user stands on one side Y1 in the second direction Y of the desk 100 and lifts and moves the tabletop 20, they are more likely to notice items hung on the hook 3, thus preventing them from forgetting items after last use.

[0070] Furthermore, hook 3 is located in the center of the tabletop 20 in the first direction X. Therefore, when a user stands on one side Y1 in the second direction Y of the desk 100 and lifts and moves the tabletop 20 with both hands, the weight of the items hung on hook 3 is evenly distributed across both hands, allowing the desk 100 to be moved in a balanced manner.

[0071] Furthermore, in a plan view, the hook 3 is positioned overlapping the tabletop 20. Therefore, since the hook 3 does not protrude from the tabletop 20, it does not get in the way of the user of the desk 100. In addition, even if multiple desks 100 are arranged so that their tabletops 20 are adjacent to each other, the hooks 3 do not come into contact with each other, thus preventing damage to the hooks 3.

[0072] Furthermore, the leg portion 10A, which is equipped with casters 12, and the leg portion 10B, which is equipped with casters 12, The tabletop 20 can be stably supported by the four legs 10C and 10D, which do not have casters.

[0073] Furthermore, a display mounting member 4 is provided directly above the hook 3 on the tabletop 20. When the engaging portion b2 of the battery-containing bag b1 is hooked onto the hook 3, the distance between the battery and the display D is shortened, making it easy to supply power from the battery to the display D. Also, because the power supply cable is shortened, it does not get in the way when moving the desk 100. In addition, in long exercises where team formations are changed as needed, the desk 100 may be moved frequently, but even when commercial power is difficult to access, the display can be used for extended periods.

[0074] Furthermore, the hook 3 and the display mounting member 4 are fixed together as a single unit to the top plate 20. Therefore, the fixing parts can be arranged more compactly than if the fixing parts of the hook 3 and the display mounting member 4 were separate.

[0075] (Variation 1) Next, a table relating to Modification 1 of one embodiment of the present invention will be described mainly with reference to Figure 5. In the modifications described below, components corresponding to the embodiments shown above may be denoted by the same reference numerals and their descriptions may be omitted.

[0076] As shown in Figure 5, the engaging body 3A has a restricting surface portion 10b and an engaging surface portion 16a.

[0077] The leg portion 10 is provided with an engaging body 3A. The leg portion 10 has a surface 10a facing one side Y1 of the second direction Y. In the middle of the leg portion 10 in the vertical direction, a restricting surface portion 10b facing one side Y1 of the second direction Y is positioned on the other side Y2 of the second direction Y than surface 10a.

[0078] An engaging extension 16 is provided at the boundary between the surface 10a of the leg portion 10 and the regulating surface portion 10b. The engaging extension 16 extends gradually upward as it moves toward one side Y1 in the second direction Y. The engaging surface portion 16a, which is the upper surface of the engaging extension 16, faces upward. The engaging surface portion 16a extends gradually upward as it moves toward one side Y1 in the second direction Y.

The engaged portion b2 is positioned at the corner between the engaging surface portion 16a of the engaging extension portion 16 and the restricting surface portion 10b of the leg portion 10.

[0080] When one side Y1 in the second direction Y of the tabletop 20 of the desk 100 is raised upward, the engaged portion b2 is positioned at the corner between the engaged surface portion 16a of the engaging extension portion 16 and the restricting surface portion 10b of the leg portion 10. The upper part of the engaged portion b2 attempts to move toward the leg portion 10 due to the weight of the items stored in the bag b1, but its movement is restricted when it hits the restricting surface portion 10b.

[0081] The restricting surface portion 10b and the engaging surface portion 16a are preferably provided on the legs 10C and 10D located on one side Y1 of the second direction Y, but they may also be provided on the legs 10A and 10B. Furthermore, the restricting surface portion 10b and the engaging surface portion 16a may be provided on multiple legs 10.

[0082] In the desk 100A configured in this way, when moving the desk 100A, the tabletop 20 is lifted so that one side Y1 in the second direction Y is upward, and the desk is moved by running it on the floor surface F using the casters 12 of the legs 10A and 10B provided on the other side Y2 in the second direction Y. An item engaged with the engaging surface 16a of the engaging extension 16 will try to move to the other side Y2 in the second direction Y due to its own weight, but the restricting surface 10b of the leg 10 restricts its movement to the other side Y2 in the second direction Y. Therefore, when moving the desk 100A at an angle, it is possible to prevent items from falling from the engaging extension 16.

[0083] (Modification 2) Next, a table relating to a modified example 2 of one embodiment of the present invention will be described mainly with reference to Figure 6. In the modified examples described below, components corresponding to the embodiments shown above may be denoted by the same reference numerals and their descriptions may be omitted.

[0084] As shown in Figure 6, the engaging body 3B has a restricting surface portion 22a and an engaging surface portion 23a.

[0085] The end portion 20a of the top plate 20 is provided with a downward-extending overhang portion 22. The overhang portion 22 has a restricting surface portion 22a facing one side Y1 in the second direction Y. The restricting surface portion 22a extends in the vertical direction.

[0086] An extension portion 23 is provided at the lower end of the hanging portion 22, extending in one direction Y1 in the second direction Y. The engagement surface portion 23a, which is the upper surface of the extension portion 23, faces upward. An inclined wall portion 24 is provided at the tip of the extension portion 23. The inclined wall portion 24 extends so as it gradually goes upward towards one direction Y1 in the second direction Y.

[0087] The engaged portion b2 is engaged with the engaging surface portion 23a of the extension portion 23. When one side Y1 in the second direction Y of the tabletop 20 of the desk 100 is raised upward, the engaged portion b2 is positioned at the corner between the restricting surface portion 22a of the hanging portion 22 and the engaging surface portion 23a of the extension portion 23. The upper part of the engaged portion b2 attempts to move toward the hanging portion 22 due to the weight of the articles stored in the bag b1, but its movement is restricted when it hits the restricting surface portion 22a.

[0088] In the desk 100B configured in this way, when moving the desk 100B, the tabletop 20 is lifted so that one side Y1 in the second direction Y is upward, and the desk is moved by running it on the floor surface F using the casters 12 of the legs 10A and 10B provided on the other side Y2 in the second direction Y. An item engaged with the engaging surface 23a of the extension 23 will try to move to the other side Y2 in the second direction Y due to its own weight, but the restricting surface 22a of the hanging part 22 provided on the tabletop 20 restricts its movement to the other side Y2 in the second direction Y. Therefore, when tilting the desk 100B to move it, it is possible to prevent items from falling from the extension 23.
