Summary of the Invention

Problems to be Solved by the Invention

[0004] In the seat table of Patent Document 1, components for storing in the storage portion are required, and there are also restrictions on the size, arrangement, etc. of the seat table. Further, in the seat table of Patent Document 2, alignment with a groove provided in the storage portion is required, so the storage operation is not easy.

[0005] One aspect of the present disclosure aims to provide a storage mechanism for a seat table with a relatively simple configuration and improved workability during storage.

Means for Solving the Problems

[0006] One aspect of the present disclosure is a housing mechanism (1) for a table for a sheet (102) used in combination with a sheet (101). The housing mechanism (1) for the table for a sheet includes a held portion (2) provided on the table for a sheet (102), and a holding portion (3) provided in a housing portion (101A) that houses the table for a sheet (102).

[0007] The held portion (2) has at least one magnet to be adsorbed (21A, 21B). The holding portion (3) has at least one adsorbing magnet (31A, 31B) that attracts at least one magnet to be adsorbed (21A, 21B), and at least one repulsive magnet (32C) that repels at least one magnet to be adsorbed (21A, 21B).

[0008] According to such a configuration, the held portion (2) of the table for a sheet (102) is guided to the housing position of the housing portion (101A) by the attraction between the magnet to be adsorbed (21A, 21B) and the adsorbing magnet (31A, 31B). Further, the magnet to be adsorbed (21A, 21B) is guided toward the adsorbing magnet (31A, 31B) by the repulsion between the magnet to be adsorbed (21A, 21B) and the repulsive magnet (32C). As a result, the workability during housing the table for a sheet (102) in the housing portion (101A) can be improved with a relatively simple configuration.

[0009] In one aspect of the present disclosure, the held portion (2) may further include a metal portion (22) that is adsorbed to at least one repulsive magnet (32C) in a state where the held portion (2) is held by the holding portion (3). According to such a configuration, the holding force of the held portion (2) by the holding portion (3) can be increased by the adsorption of the metal portion (22) to the repulsive magnet (32C).

[0010] In one aspect of the present disclosure, at least one adsorption magnet (31A, 31B) may include a first adsorption magnet (31A) and a second adsorption magnet (31B) that are arranged apart from each other in a first direction. At least one magnet to be adsorbed (21A, 21B) may include a first magnet to be adsorbed (21A) that is adsorbed to the first adsorption magnet (31A) and a second magnet to be adsorbed (21B) that is adsorbed to the second adsorption magnet (31B) in a state where the held portion (2) is held by the holding portion (3). The holding portion (3) is arranged between the first adsorption magnet (31A) and the second adsorption magnet (31B) in the first direction, and has a protruding portion (33) that protrudes toward the held portion (2) more than the first adsorption magnet (31A) and the second adsorption magnet (31B) in a state where the held portion (2) is held by the holding portion (3). At least one repulsive magnet (32C) may be arranged on the protruding portion (33). According to such a configuration, the induction effect of the magnets to be adsorbed (21A, 21B) on the adsorption magnets (31A, 31B) due to the repulsion between the magnets to be adsorbed (21A, 21B) and the repulsive magnet (32C) can be enhanced.

[0011] In one aspect of the present disclosure, the accommodating portion (101A) may be provided on the seat (101). According to such a configuration, when designing the seat (101) and the seat table (102), the design of the held portion (2) and the holding portion (3) can be carried out in combination.

[0012] In one aspect of the present disclosure, the accommodating portion (101A) may be an armrest of the seat (101). According to such a configuration, it becomes easy to accommodate and take out the seat table (102) in a seated state. In addition, the space below the armrest can be effectively utilized.

[0013] Note that the reference signs in the above parentheses are examples showing the correspondence with the specific configurations and the like described in the embodiments to be described later, and the present disclosure is not limited to the specific configurations and the like indicated by the reference signs in the above parentheses.

[0015] Hereinafter, embodiments to which the present disclosure is applied will be described with reference to the drawings. [1. First Embodiment] [1-1. Configuration] The storage mechanism 1 of the table for the seat shown in FIG. 1 is a mechanism for storing the table for the seat 102 used in combination with the seat 101. The storage mechanism 1 of the table for the seat includes a held portion 2 provided on the table for the seat 102 and a holding portion 3 provided on the first armrest 101A.

[0016] The table for the seat 102 is configured to be detachable from the first armrest 101A at the storage position set on the first armrest 101A. The table for the seat 102 can be moved from the stored state accommodated in the first armrest 101A of the seat 101 shown in FIG. 1 to the use state shown in FIG. 2 by the hand of the seated person.

[0017] In the use state, the table for the seat 102 is installed so as to straddle the first armrest 101A and the second armrest 101B of the seat 101. That is, the table for the seat 102 can be disposed on the first armrest 101A and the second armrest 101B.

[0018] The seat 101 is, for example, a seat for vehicles such as automobiles, railway vehicles, ships, and aircraft. Further, the seat 101 may be a seat arranged in facilities such as movie theaters and theaters.

[0019] The first armrest 101A and the second armrest 101B of the seat 101 are parts that support the arms of the seated person. The first armrest 101A is arranged to the left of the second armrest 101B. However, the first armrest 101A may be arranged to the right of the second armrest 101B. That is, the seat table 102 may be housed in the left armrest or the right armrest.

[0020] <Seat table> As shown in FIGS. 3A and 3B, the seat table 102 includes a table body 102A, a first leg portion 102B, a second leg portion 102C, and a held portion 2. Note that the directions shown in FIGS. 3A and 3B are the directions in a state where the seat table 102 is housed in the first armrest 101A which is a housing portion.

[0021] The table body 102A is a plate-shaped part having a top surface for placing articles in a use state. The table body 102A is made of a non-magnetic material such as resin, for example.

[0022] The first leg portion 102B extends from the front end of the table body 102A in the accommodation state (that is, the state where the held portion 2 is held by the holding portion 3 of the first armrest 101A) inward in the seat width direction (that is, downward in the use state). The second leg portion 102C extends from the rear end of the table body 102A in the accommodation state inward in the seat width direction. The first leg portion 102B and the second leg portion 102C are each made of a non-magnetic material such as resin, for example.

[0023] The held part 2 is a part held by a holding part 3 provided on the first armrest 101A. The held part 2 has a first magnet to be adsorbed 21A, a second magnet to be adsorbed 21B, and a metal part 22.

[0024] The first magnet to be adsorbed 21A is disposed above the inner end (i.e., the tip) in the seat width direction of the first leg part 102B in the housed state. The second magnet to be adsorbed 21B is disposed above the inner end in the seat width direction of the second leg part 102C in the housed state.

[0025] The first magnet to be adsorbed 21A and the second magnet to be adsorbed 21B are arranged apart from each other in the front-rear direction (i.e., the width direction of the table) in the housed state. Further, in the housed state, the first magnet to be adsorbed 21A and the second magnet to be adsorbed 21B are each disposed outside in the front-rear direction and inside in the seat width direction with respect to the table body 102A.

[0026] The metal part 22 is a strip-shaped metal plate disposed at the upper end of the inner surface in the seat width direction (i.e., the lower surface in the use state) of the table body 102A in the housed state. The metal part 22 is disposed between the first magnet to be adsorbed 21A and the second magnet to be adsorbed 21B in the front-rear direction in the housed state.

[0027] <First armrest> As shown in FIGS. 4A and 4B, the first armrest 101A has a cover 101C and a holding part 3.

[0028] The cover 101C is a member that covers the frame and the like of the first armrest 101A and constitutes the design of the first armrest 101A. The cover 101C is made of a non-magnetic material such as resin, for example.

[0029] The holding part 3 has a first adsorbing magnet 31A, a second adsorbing magnet 31B, a first repulsive magnet 32A, a second repulsive magnet 32B, a third repulsive magnet 32C, a fourth repulsive magnet 32D, and a protruding part 33.

[0030] The first adsorption magnet 31A is disposed inside the cover 101C at the front end of the first armrest 101A. The first adsorption magnet 31A is disposed at a position where it can adsorb the first magnet to be adsorbed 21A with the cover 101C interposed therebetween.

[0031] The second adsorption magnet 31B is disposed inside the cover 101C at the rear end of the first armrest 101A. The second adsorption magnet 31B is disposed at a position where it can adsorb the second magnet to be adsorbed 21B with the cover 101C interposed therebetween.

[0032] The first adsorption magnet 31A and the second adsorption magnet 31B are arranged apart from each other in the front-rear direction. The distance between the first adsorption magnet 31A and the second adsorption magnet 31B is the same as the distance between the first magnet to be adsorbed 21A and the second magnet to be adsorbed 21B in the held portion 2.

[0033] The protrusion 33 is disposed between the first adsorption magnet 31A and the second adsorption magnet 31B in the front-rear direction and protrudes more than the first adsorption magnet 31A and the second adsorption magnet 31B toward the outside in the seat width direction (that is, the left side).

[0034] In other words, the protrusion 33 protrudes toward the held portion 2 in a state where the held portion 2 is held by the holding portion 3. The protrusion 33 has a trapezoidal shape whose width in the front-rear direction becomes smaller toward the left side when viewed from the up-down direction. The tip portion (that is, the left end portion) of the protrusion 33 faces or contacts the back surface of the table body 102A when the seat table 102 is accommodated.

[0035] The first repulsive magnet 32A, the second repulsive magnet 32B, the third repulsive magnet 32C, and the fourth repulsive magnet 32D respectively repel the first magnet to be adsorbed 21A and the second magnet to be adsorbed 21B.

[0036] The first repulsive magnet 32A is disposed inside a portion of the cover 101C that constitutes the inclined surface on the front side of the protruding portion 33 (i.e., the surface inclined with respect to both the front-rear direction and the sheet width direction). The first repulsive magnet 32A is located at the most front side among the repulsive magnets 32A - 32D and is closest to the first attracting magnet 31A.

[0037] The second repulsive magnet 32B is disposed inside a portion of the cover 101C that constitutes the inclined surface on the rear side of the protruding portion 33. The second repulsive magnet 32B is located at the most rear side among the repulsive magnets 32A - 32D and is closest to the second attracting magnet 31B.

[0038] The third repulsive magnet 32C and the fourth repulsive magnet 32D are disposed inside a portion of the cover 101C that constitutes the surface on the outer side in the sheet width direction of the protruding portion 33 (i.e., the protruding end surface). The third repulsive magnet 32C and the fourth repulsive magnet 32D are located between the first repulsive magnet 32A and the second repulsive magnet 32B in the front-rear direction. Also, the third repulsive magnet 32C and the fourth repulsive magnet 32D are located on the outer side in the sheet width direction than the first attracting magnet 31A and the second attracting magnet 31B.

[0039] The first attracting magnet 31A, the second attracting magnet 31B, the first repulsive magnet 32A, the second repulsive magnet 32B, the third repulsive magnet 32C, and the fourth repulsive magnet 32D are arranged side by side in the front-rear direction as viewed from the sheet width direction. In other words, there is a virtual plane that is orthogonal to the vertical direction and passes through all of these magnets.

[0040] As shown in FIG. 5, in a state where the held portion 2 is held by the holding portion 3, the first magnet to be attracted 21A is attracted to the first attracting magnet 31A, and the second magnet to be attracted 21B is attracted to the second attracting magnet 31B. Also, the metal portion 22 of the sheet table 102 is attracted to the third repulsive magnet 32C and the fourth repulsive magnet 32D in a state where the held portion 2 is held by the holding portion 3.

[0041] When the seat table 102 is received in the first armrest 101A, if the seat table 102 moves in the mounting direction D with the first magnet to be adsorbed 21A shifted rearward from the first adsorbing magnet 31A, the first repulsive magnet 32A and the third repulsive magnet 32C push the first magnet to be adsorbed 21A forward. As a result, the first magnet to be adsorbed 21A is induced toward the first adsorbing magnet 31A. The mounting direction D is a direction from the outside to the inside in the seat width direction (that is, a direction toward the right side).

[0042] Similarly, when the seat table 102 moves in the mounting direction D with the second magnet to be adsorbed 21B shifted forward from the second adsorbing magnet 31B, the second repulsive magnet 32B and the fourth repulsive magnet 32D push the second magnet to be adsorbed 21B rearward. As a result, the second magnet to be adsorbed 21B is induced toward the second adsorbing magnet 31B.

[0043] Note that the housing mechanism 1 of the seat table may further include a locking mechanism that fixes the held portion 2 to the holding portion 3 in a state where the seat table 102 is housed in the first armrest 101A. The locking mechanism is composed of, for example, a claw as an engaging portion and a fitting hole as an engaged portion with which the engaging portion engages.

[0044] [1-2. Effect] According to the embodiment described in detail above, the following effects can be obtained. (1a) By attracting the magnets to be adsorbed 21A and 21B and the adsorbing magnets 31A and 31B, the held portion 2 of the seat table 102 is guided to the housing position of the first armrest 101A which is the housing portion.

[0045] Furthermore, by the magnets to be adsorbed 21A and 21B and the repulsive magnets 32A - 32D repelling each other, the magnets to be adsorbed 21A and 21B are induced toward the adsorbing magnets 31A and 31B. As a result, with a relatively simple configuration, the workability when the seat table 102 is housed in the first armrest 101A is improved.

[0046] (1b) By adsorbing the repulsive magnets 32C and 32D to the metal part 22, the holding force of the held part 2 by the holding part 3 can be increased.

[0047] (1c) By arranging the repulsive magnets 32A - 32D on the protruding part 33, the induction effect of the adsorbed magnets 21A and 21B on the adsorption magnets 31A and 31B due to the repulsion between the adsorbed magnets 21A, 21B and the repulsive magnets 32A - 32D can be enhanced.

[0048] (1d) By providing a housing part for housing the seat table 102 on the seat 101, when designing the seat 101 and the seat table 102, the design of the held part 2 and the holding part 3 can be carried out in combination.

[0049] (1e) Since the housing part for housing the seat table 102 is the first armrest 101A, the housing and removal of the seat table 102 in the seated state become easy. Also, the space below the first armrest 101A can be effectively utilized.

[0050] [2. Other Embodiments] As described above, the embodiments of the present disclosure have been explained, but it goes without saying that the present disclosure is not limited to the above embodiments and can take various forms.

[0051] (2a) In the housing mechanism of the seat table of the above embodiment, the held part does not necessarily have to have a metal part adsorbed by the repulsive magnet. (2b) In the housing mechanism of the seat table of the above embodiment, the repulsive magnet does not necessarily have to be arranged on the protruding part.

[0052] (2c) In the housing mechanism of the seat table of the above embodiment, the housing part for housing the seat table does not necessarily have to be the first armrest. For example, the housing part may be provided on the seat back. Further, the housing part for housing the seat table may be provided outside the seat. For example, the housing part may be provided on a console, a wall, etc. arranged around the seat.

[0053] (2d) The functions of one component in the above embodiment may be distributed among a plurality of components, or the functions of a plurality of components may be integrated into one component. Also, a part of the configuration of the above embodiment may be omitted. Further, at least a part of the configuration of the above embodiment may be added to, replaced with, etc., the configuration of other above embodiments. Note that all aspects included in the technical idea specified from the language described in the claims are embodiments of the present disclosure.
