Description

TECHNICAL FIELD

[0001] The present disclosure relates to a storage mechanism of a table for a seat. BACKGROUND

[0002] A table for a seat is known that can be used by a seated person by being installed on a seat from a state of being stored in a storage portion around the seat (see Japanese Patent Application Publication No. 2016-132287 and Japanese Patent Application Publication No. 2020-66343). The table for a seat is configured to be stored again in the storage portion after use. SUMMARY

[0003] In the table for a seat of Japanese Patent Application Publication No. 2016-132287, it is necessary to provide a constituent member for storing the table for a seat in the storage portion, and thus there is a constraint in the size, arrangement, and the like of the table for a seat. In addition, in the table for a seat of Japanese Patent Application Publication No. 2020-66343, since alignment with a groove provided in the storage portion is necessary, the storage operation cannot be easily performed.

[0004] One aspect of the present disclosure preferably provides a storage mechanism of a table for a seat that can improve the operability at the time of storage with a relatively simple structure.

[0005] One aspect of the present disclosure relates to a storage mechanism of a table for a seat used in combination with a seat. The storage mechanism of the table for a seat includes a held portion provided on the table for a seat and a holding portion provided on a storage portion that stores the table for a seat.

[0006] The held portion has at least one adsorbed magnet. The holding portion has at least one attractive magnet that mutually attracts the at least one adsorbed magnet, the at least one attractive magnet adsorbing the at least one adsorbed magnet in a state in which the holding portion holds the held portion, and at least one repulsive magnet that mutually repels the at least one adsorbed magnet, the at least one repulsive magnet generating a magnetic force to guide the at least one adsorbed magnet toward the at least one attractive magnet when the at least one adsorbed magnet approaches the at least one attractive magnet.

[0007] According to the structure described above, the adsorbed magnet and the attractive magnet mutually attract, whereby the held portion of the table for a seat is guided to a storage position that is the storage portion. In addition, the adsorbed magnet and the repulsive magnet mutually repel, whereby the adsorbed magnet is guided toward the attractive magnet. Thus, the operability at the time when the table for a seat is stored in the storage portion can be improved with a relatively simple structure.

[0008] In one embodiment of this disclosure, the held portion may further include a metal portion, which is attracted by at least one repulsive magnet while the held portion is held by the holding portion. According to the structure described above, the metal portion is attracted by the repulsive magnet, thereby increasing the holding force exerted by the holding portion on the held portion.

[0009] In one embodiment of this disclosure, at least one adsorption magnet may include a first adsorption magnet and a second adsorption magnet, which are spaced apart from each other in a first direction. At least one attracted magnet may include a first attracted magnet and a second attracted magnet, wherein, with the holding portion holding the held portion, the first attracted magnet is attracted by the first adsorption magnet, and the second attracted magnet is attracted by the second adsorption magnet. The holding portion may have a protrusion disposed between the first and second adsorption magnets in the first direction, and, with the holding portion holding the held portion, the protrusion protrudes towards the held portion beyond the first and second adsorption magnets. At least one repulsive magnet may be disposed on the protrusion. According to the structure described above, the effect of guiding the attracted magnet towards the adsorption magnet by means of the repulsion between the attracted magnet and the repulsive magnet can be improved.

[0010] In one embodiment of this disclosure, the storage section can be installed on the seat. Based on the structure described above, the design of the storage section and the holding section can be carried out simultaneously when designing the seat and the table for the seat.

[0011] In one embodiment of this disclosure, the storage unit can be the armrest of the chair. According to the structure described above, it is easy to store and retrieve the table while seated. Furthermore, the space beneath the armrest can be utilized effectively. Attached Figure Description

[0018] The embodiments of which this disclosure is applied will be described below with reference to the accompanying drawings.

[0019] [1. First Embodiment]

[0020] [1-1. Structure]

[0021] Figure 1 The storage mechanism 1 for the chair table shown is a mechanism for storing the chair table 102 used in combination with the chair 101. The storage mechanism 1 for the chair table includes a holding part 2 and a holding part 3. The holding part 2 is provided on the chair table 102, and the holding part 3 is provided on the first armrest 101A.

[0022] The chair table 102 is configured to be installable and detachable relative to the first armrest 101A from its storage position. The chair table 102 can be moved using the user's hand. Figure 1 The storage state shown is transferred from the first armrest 101A of the seat 101 to the storage state. Figure 2 The usage status is shown.

[0023] In use, the seat table 102 is arranged across the first armrest 101A and the second armrest 101B of the seat 101. That is, the seat table 102 can be arranged on the first armrest 101A and the second armrest 101B.

[0024] Seat 101 is a seating seat used in vehicles such as automobiles, railway vehicles, ships, and aircraft. Additionally, seat 101 can also be a seating seat installed in facilities such as cinemas and theaters.

[0025] The first armrest 101A and the second armrest 101B of the seat 101 are for supporting the arms of the seated person. The first armrest 101A is located to the left of the second armrest 101B. However, the first armrest 101A can also be located to the right of the second armrest 101B. That is, the seat table 102 can be stored in either the left armrest or the right armrest.

[0026]

[0027] like Figure 3A as well as Figure 3B As shown, the seating table 102 includes a table body 102A, a first leg 102B, a second leg 102C, and a retaining part 2. Furthermore,Figure 3A and Figure 3B The direction shown is a direction when the seat table 102 is in a state of being housed in the first armrest 101A serving as a housing portion.

[0028] The table main body 102A is a portion in a plate shape, which has a table surface for placing articles in a use state. The table main body 102A is formed of a material, such as resin, which does not have magnetism.

[0029] The first leg portion 102B extends from a front end portion of the table main body 102A in a state of being housed (i.e., a state in which the holding portion 3 of the first armrest 101A holds the held portion 2) toward an inside in a seat width direction (i.e., a lower side in the use state). The second leg portion 102C extends from a rear end portion of the table main body 102A in the state of being housed toward the inside in the seat width direction. The first leg portion 102B and the second leg portion 102C are each formed of a material, such as resin, which does not have magnetism.

[0030] The held portion 2 is a portion held by the holding portion 3 provided in the first armrest 101A. The held portion 2 has a first attracted magnet 21A, a second attracted magnet 21B, and a metal portion 22.

[0031] The first attracted magnet 21A is disposed at an upper portion of an end portion (i.e., a front end portion) on the inside in the seat width direction in the first leg portion 102B in the state of being housed. The second attracted magnet 21B is disposed at an upper portion of an end portion on the inside in the seat width direction in the second leg portion 102C in the state of being housed.

[0032] The first attracted magnet 21A and the second attracted magnet 21B are disposed apart from each other in a front-rear direction (i.e., a width direction of the table) in the state of being housed. Further, in the state of being housed, the first attracted magnet 21A and the second attracted magnet 21B are each disposed at a position on the outside in the front-rear direction from the table main body 102A and on the inside in the seat width direction from the table main body 102A.

[0033] The metal portion 22 is a metal plate in a band shape, which is disposed at an upper end portion of a surface (i.e., a lower surface in the use state) on the inside in the seat width direction in the table main body 102A in the state of being housed. The metal portion 22 is disposed between the first attracted magnet 21A and the second attracted magnet 21B in the front-rear direction in the state of being housed.

[0034] <First armrest>

[0035] As shown in Figs. 1 and 2, the first armrest 101A has a cover portion 101C and a holding portion 3. Figure 4A and Figure 4B As shown in Figs. 1 and 2, the first armrest 101A has a cover portion 101C and a holding portion 3.

[0036] The cover portion 101C is a member that covers the frame and the like of the first armrest 101A, and forms the appearance of the first armrest 101A. The cover portion 101C is formed of a material, such as resin, that does not have magnetism.

[0037] The holding portion 3 has a first adsorption magnet 31A, a second adsorption magnet 31B, a first repulsion magnet 32A, a second repulsion magnet 32B, a third repulsion magnet 32C, a fourth repulsion magnet 32D, and a protruding portion 33.

[0038] The first adsorption magnet 31A is disposed on the inner side of the cover portion 101C at the front end portion of the first armrest 101A. The first adsorption magnet 31A is disposed at a position at which the first adsorption magnet 31A can adsorb the first adsorbed magnet 21A through the cover portion 101C.

[0039] The second adsorption magnet 31B is disposed on the inner side of the cover portion 101C at the rear end portion of the first armrest 101A. The second adsorption magnet 31B is disposed at a position at which the second adsorption magnet 31B can adsorb the second adsorbed magnet 21B through the cover portion 101C.

[0040] The first adsorption magnet 31A and the second adsorption magnet 31B are disposed 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 adsorbed magnet 21A and the second adsorbed magnet 21B in the held portion 2.

[0041] The protruding portion 33 is disposed between the first adsorption magnet 31A and the second adsorption magnet 31B in the front-rear direction, and protrudes further outward in the seat width direction (i.e., to the left) than the first adsorption magnet 31A and the second adsorption magnet 31B.

[0042] In other words, the protruding portion 33 protrudes toward the held portion 2 in a state in which the holding portion 3 is holding the held portion 2. When viewed in the up-down direction, the protruding portion 33 has a trapezoidal shape in which the width in the front-rear direction decreases toward the left. When the seat table 102 has been stored, the front end portion (i.e., the left end portion) of the protruding portion 33 faces or contacts the back surface of the table main body 102A.

[0043] The first repulsion magnet 32A, the second repulsion magnet 32B, the third repulsion magnet 32C, and the fourth repulsion magnet 32D each repel the first adsorbed magnet 21A and the second adsorbed magnet 21B.

[0044] The first repulsion magnet 32A is disposed on the inner side of the portion of the cover portion 101C that constitutes the front-side inclined surface (i.e., a surface that is inclined with respect to both the front-rear direction and the seat width direction) of the protruding portion 33. The first repulsion magnet 32A is located at the most front side among the repulsion magnets 32A to 32D, and is located closest to the first adsorption magnet 31A.

[0045] The 2nd repulsion magnet 32B is disposed at the inner side of the portion of the rear side inclined surface of the protruding portion 33 in the cover portion 101C. The 2nd repulsion magnet 32B is located at the most rear side among the repulsion magnets 32A to 32D, and is located closest to the 2nd attraction magnet 31B.

[0046] The 3rd repulsion magnet 32C and the 4th repulsion magnet 32D are disposed at the inner side of the portion of the surface of the protruding portion 33 at the seat width direction outer side (i.e., the protruding end surface) in the cover portion 101C. The 3rd repulsion magnet 32C and the 4th repulsion magnet 32D are located between the 1st repulsion magnet 32A and the 2nd repulsion magnet 32B in the front-rear direction. Further, the 3rd repulsion magnet 32C and the 4th repulsion magnet 32D are located at positions closer to the seat width direction outer side than the 1st attraction magnet 31A and the 2nd attraction magnet 31B.

[0047] When viewed from the seat width direction, the 1st attraction magnet 31A, the 2nd attraction magnet 31B, the 1st repulsion magnet 32A, the 2nd repulsion magnet 32B, the 3rd repulsion magnet 32C, and the 4th repulsion magnet 32D are arranged in the front-rear direction. In other words, there is a virtual plane orthogonal to the up-down direction and passing through all of these magnets.

[0048] As shown in FIG. 6, in a state where the holding portion 3 is holding the held portion 2, the 1st held attraction magnet 21A is attracted by the 1st attraction magnet 31A, and the 2nd held attraction magnet 21B is attracted by the 2nd attraction magnet 31B. Further, the metal portion 22 of the seat table 102 is attracted by the 3rd repulsion magnet 32C and the 4th repulsion magnet 32D in a state where the holding portion 3 is holding the held portion 2. Figure 5

[0049] To stow the seat table 102 at the 1st armrest 101A, if the seat table 102 is moved in the installation direction D in a state where the 1st held attraction magnet 21A is displaced to a position closer to the rear side than the 1st attraction magnet 31A, the 1st held attraction magnet 21A is pushed forward by the 1st repulsion magnet 32A and the 3rd repulsion magnet 32C. Thus, the 1st held attraction magnet 21A is guided toward the 1st attraction magnet 31A. Here, the installation direction D is a direction from the seat width direction outer side toward the inner side (i.e., a direction toward the right side).

[0050] Likewise, if the seat table 102 is moved in the installation direction D in a state where the 2nd held attraction magnet 21B is displaced to a position closer to the front side than the 2nd attraction magnet 31B, the 2nd held attraction magnet 21B is pushed rearward by the 2nd repulsion magnet 32B and the 4th repulsion magnet 32D. Thus, the 2nd held attraction magnet 21B is guided toward the 2nd attraction magnet 31B.

[0051] ​Further, the storage mechanism 1 of the seat table can also have a locking mechanism that fixes the held portion 2 to the holding portion 3 in a state where the seat table 102 is stored in the first armrest 101A. The locking mechanism can be constituted by, for example, a claw as an engaging portion, a fitting hole as an engaged portion to which the engaging portion is engaged, or the like.

[0052] [1-2. Effects]

[0053] According to the above-described embodiments, the following effects can be obtained.

[0054] (1a) The held portion 2 of the seat table 102 is guided to the storage position of the first armrest 101A as the storage portion by the mutual attraction of the adsorbed magnets 21A, 21B and the adsorbed magnets 31A, 31B.

[0055] Further, the adsorbed magnets 21A, 21B and the repulsive magnets 32A-32D are mutually repulsive, whereby the adsorbed magnets 21A, 21B are guided toward the adsorbed magnets 31A, 31B. Thus, the operability when the seat table 102 is stored in the first armrest 101A can be improved with a relatively simple structure.

[0056] (1b) The metal portion 22 is adsorbed by the repulsive magnets 32C, 32D, whereby the holding force of the holding portion 3 acting on the held portion 2 can be improved.

[0057] (1c) The repulsive magnets 32A-32D are disposed in the protruding portion 33, whereby the effect of guiding the adsorbed magnets 21A, 21B toward the adsorbed magnets 31A, 31B by the repulsion between the adsorbed magnets 21A, 21B and the repulsive magnets 32A-32D can be improved.

[0058] (1d) The storage portion that stores the seat table 102 is provided on the seat 101, whereby the design of the held portion 2 and the holding portion 3 can be performed in conjunction with the design of the seat 101 and the seat table 102.

[0059] (1e) The storage portion that stores the seat table 102 is the first armrest 101A, whereby the storage and extraction of the seat table 102 can be easily performed in a seated state. Further, the space below the first armrest 101A can also be effectively utilized.
