  EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated using drawing.

  First, the configuration of the table 10 according to the first embodiment will be described with reference to FIGS. As shown in FIGS. 1 to 6, the table 10 according to the present embodiment has a configuration that can be deployed and stored in the seat 1 of an automobile. Here, the seat 1 includes a seat back 2 that serves as a backrest for a seated person, and a seat cushion 3 that serves as a seating portion, and a support base that extends upward on a standing wall on the left and right sides of the seat cushion 3. 4 is provided. Each support base 4 has an armrest 5 on the upper surface thereof, so that a seated person can use it as an armrest.

  The table 10 described above includes a table main body 11 serving as an object table, and a table moving device 10M that connects the table main body 11 to a state in which the table main body 11 can be moved with respect to the support base 4 provided on the left side of the sheet 1 described above. It has a configuration. Here, the support 4 provided on the left side of the seat 1 corresponds to the “base” of the present invention. Specifically, the table moving device 10M described above is in a horizontal posture at the storage position (the position shown in FIGS. 4 to 6) in which the table body 11 is stored in the support base 4 and the front of the seated person. It can be moved between the use position (position shown in FIGS. 1 to 3) developed in FIG. Here, the armrest 5 on the upper surface of the support base 4 provided on the left side of the seat 1 for storing the table main body 11 described above is opened to the outside when the table main body 11 is unfolded and stored, so that the internal space of the support base 4 can be opened. It is in a state where it is hinged to the upper surface of the support base 4 so as to be openable and closable so that it can be opened upward.

  As shown in FIGS. 1 to 3, the table moving device 10 </ b> M described above has a support arm 12 that supports the table main body 11 with respect to the support base 4, and a state in which the table main body 11 is deployed to the use position from the front outer side. A swivel mechanism 13 that pushes and retracts the support arm 12 and a slider 14 that connects the support arm 12 to a state in which the support arm 12 can slide in the height direction with respect to the support base 4 are provided. As shown in FIGS. 4 to 6 and FIGS. 7 to 8, the slider 14 described above is assembled so as to be movable only in the height direction with respect to the guide rail 4 </ b> A provided inside the support base 4. It is supposed to be in a state.

  Specifically, the slider 14 described above has guide rails 4 </ b> A that extend in the height direction provided at the front and rear positions of the slider 14 inside the support base 4, with each fitting portion 14 </ b> A projecting like a standing plate before and after the slider 14. By being fitted in each of the rail grooves 4A1, they are guided and assembled so as to be movable only in the height direction along the shape of each rail groove 4A1. As shown in FIGS. 7 to 8, the slider 14 slides upward in the rail groove 4A1 when each fitting portion 14A that slides in the rail groove 4A1 hits the upper end surface of the rail groove 4A1. It is designed to be locked.

  The support arm 12 is configured by a flat plate member having a narrower plate width in the front-rear direction than the table main body 11, and a lower end of the support arm 12 is a rotary shaft whose axial direction is directed in the front-rear direction of the seat with respect to the upper portion of the slider 14 described above. 12A is connected in a rotatable manner. As a result, as shown in FIGS. 4 to 6 and FIGS. 7 to 8, the support arm 12 stands up straight on the above-described slider 14 and rises in the height direction with respect to the support base 4. As shown in FIGS. 9 to 10, it can be put in and out, or it can be tilted to the inside of the seat around the rotating shaft 12 </ b> A so as to protrude from the support base 4 to the inside of the seat. ing.

  In detail, the support arm 12 described above is moved as shown in FIGS. 7 to 8 when the slider 14 is moved to a position where the upward movement of the support base 4 is locked. As shown in FIGS. 9 to 10, the support 4 can be pushed down in the form of projecting from the opening 4 </ b> B formed in the seat inner side to the seat inner side. In the state where the slider 14 is pulled up only to a lower position than the above, the support arm 12 hits the inner side wall 4C of the support base 4 so that the support arm 4 cannot be pushed down. It has become.

  When the support arm 12 is tilted down to the state shown in FIGS. 9 to 10, the stopper piece 12 </ b> C formed on the inner side surface portion of the seat at the lower end portion serving as the base side is formed on the inner side wall 4 </ b> C of the support base 4. The stopper face 4C1 formed on the upper surface portion of the stopper is tilted so as to be locked at the illustrated inclined position. The stopper piece 12 </ b> C described above is brought into contact with the stopper surface 4 </ b> C <b> 1 formed on the upper surface portion of the inner side wall 4 </ b> C of the support base 4 described above in a straight line in the height direction. By the surface contact, the downward movement of the slider 14 connected to the support arm 12 described above is held and the load applied to the support arm 12 from the table body 11 is received. ing.

  As shown in FIGS. 1 to 3, the table main body 11 is configured by a flat plate member, and the upper end portion of the support arm 12 described above is directed axially in the front-rear direction of the seat at an intermediate portion on the back surface side thereof. The rotary shaft 12B is connected in a rotatable manner. Thereby, the table main body 11 is in a state in which it can swing with respect to the support arm 12 described above around the rotation shaft 12B. Specifically, as shown in FIGS. 9 to 10, the table main body 11 described above is supported in a state where the above-described support arm 12 is pulled out from the inside of the support base 4 and tilted obliquely inside the seat. The neck with respect to the support arm 12 between the obliquely inclined position where the shape is superimposed on the arm 12 and the use position dropped from the inclined position to the horizontal angle as shown in FIGS. It can be rotated up and down by swinging motion.

  As shown in FIGS. 9 to 10, the table main body 11 described above is in a tilted position where the shape is superimposed on the support arm 12 as described above, and as shown in FIGS. 14 is folded up in a state of standing straight upward, or is dropped into the support base 4 together with the support arm 12 as shown in FIGS. Further, the table main body 11 is opened from the state accommodated in the support base 4 by opening the armrest 5 to the outside and pulling up the table main body 11 exposed to the inside to the upper side, as shown in FIGS. As shown in FIG. 4, the slider 14 is pulled out to the upper part of the support base 4 while sliding the slider 14 together with the support arm 12. And after the table main body 11 is pulled out to the upper part of the said support stand 4, by rotating so that it may incline inside a sheet | seat with respect to the slider 14 with the support arm 12, as shown in FIGS. 9-10, The support arm 12 and the support arm 12 are deployed in a posture inclined obliquely upward inside the seat.

  Then, the table main body 11 is deployed in the oblique angle posture, so that the table main body 11 is brought into a horizontal angle around the rotation shaft 12B with the support arm 12 by its own weight and is locked (FIG. 11). To FIG. 12). Here, the rotary shaft 12B that connects the table main body 11 and the support arm 12 is set at a position closer to the seat outer side than the central portion of the table main body 11 in the lateral width direction (rotational radius direction). By being set in this way, the table main body 11 is lowered to the use position of the horizontal posture by its own weight by being developed to the oblique angle posture shown in FIGS. 9 to 10 together with the support arm 12. It is supposed to be. In addition, the table main body 11 is configured to be easily maintained in a state in which it is difficult to jump to the above-described tilted position by its own weight even when the table body 11 is dropped into the use position of the horizontal posture by the above setting. .

  When the table main body 11 described above is dropped to the use position in the horizontal posture, a locking mechanism 12D formed at the distal end of the support arm 12 is provided at the bottom of the table main body 11 described later. It hits the bottom of 13 fixed plates 13B, and the rotation in the dropping direction is locked.

  As shown in FIG. 14, the table main body 11 is pushed forward by the seated person in the state where the table main body 11 is deployed to the use position of the horizontal posture shown in FIGS. 1 to 3 described above. The swivel mechanism 13 set in the vicinity of the connecting portion with the support arm 12 is pushed forward by the outer side of the seat. By this turning rotation, the table main body 11 is in a state of being pushed away to a retracted position that does not get in the way when the seated person leaves the seat 1. Specifically, the table body 11 is pushed and moved by the operation of the turning mechanism 13 from the use position of the front part of the seated person to the position where the shape is superimposed on the upper part of the support base 4 that supports the table body 11. ing.

  At this time, as shown in FIG. 15, the table main body 11 moves while raising the height position in accordance with the turning movement from the use position to the retracted position. As a result, the table main body 11 is retracted to a state where it does not interfere with the armrest 5 at the upper part of the support base 4. Further, the table body 11 is naturally returned to the original use position by an urging structure described later set in the turning mechanism 13 by removing the force pushed away to the retracted position. ing.

  With this configuration, the table main body 11 is naturally moved from the retracted position within the installation area of the seat 1 by the seat occupant pushing the table main body 11 outward and moving away from the seat 1. It is returned to a certain use position so that the shape does not protrude from the outer region of the sheet 1. In addition, the table body 11 is automatically returned to the original use position even when the table body 11 is moved from the use position to the retracted position and seated on the seat 1 so that the occupant can sit on the seat 1. It is supposed to be possible.

  The specific structure of the turning mechanism 13 will be described. The turning mechanism 13 is provided at the bottom portion of the table main body 11, and the table main body 11 is connected to the upper end of the support arm 12 so as to be turnable. It has become. Specifically, the turning mechanism 13 includes a movable plate 13A fixed to the bottom of the table body 11, a fixed plate 13B connected to the upper end of the support arm 12 by the rotary shaft 12B, and the fixed plate 13B. And a spring 13C hooked between the movable plate 13A. Here, the movable plate 13A corresponds to the “support portion” of the present invention, and the fixed plate 13B corresponds to the “guide portion” of the present invention.

  The above-described movable plate 13A is fitted into a cylindrical portion 13B1 formed in a cylindrical shape in the height direction on the fixed plate 13B, and is provided so as to be able to rotate in a turning direction about the cylindrical portion 13B1. It is supposed to be in a state. Specifically, as shown in FIGS. 13 and 16, the movable plate 13A and the fixed plate 13B include a slide pin 13A1 provided on the inner peripheral portion of the hole of the movable plate 13A fitted in the cylindrical portion 13B1 described above. The slide pin 13A1 slides along the shape of the guide groove 13B2 as being fitted in a guide groove 13B2 formed in the outer peripheral portion of the cylindrical portion 13B1 of the fixed plate 13B and extending in a spiral shape in the height direction. It is supposed to be assembled in the state. The movable range of the movable plate 13A with respect to the fixed plate 13B is restricted within the movable range in which the slide pin 13A1 can slide along the shape of the guide groove 13B2. With this restricting structure, the movable plate 13A rotates with respect to the fixed plate 13B only within a range in which the table body 11 is moved between the use position and the retracted position.

  With this structure, the movable plate 13A moves along the shape of the guide groove 13B2 as the movable plate 13A rotates in the turning direction from the use position to the retracted position with respect to the fixed plate 13B. It slides and is lifted upward by the shape of the guide groove 13B2. The slide guide structure of the slide pin 13A1 and the guide groove 13B2 described above is set at two positions in the circumferential direction. Due to the slide guide structure, the movable plate 13A is moved in the turning direction and the height direction while keeping the angle in the height direction with respect to the fixed plate 13B in a constant state, and the table main body 11 is moved horizontally. It can be moved between the use position and the retracted position while maintaining the posture state.

  A spring 13C (tensile spring) is hooked between the outer peripheral portions of the movable plate 13A and the fixed plate 13B. Due to the biasing force of the spring 13C, the movable plate 13A is always in a state of receiving a biasing force in a direction returning from the retracted position toward the use position with respect to the fixed plate 13B. Is always held at the use position. The table body 11 is returned from the retracted position to the use position by removing the force pushed away from the use position to the retracted position by the biasing force of the spring 13C. Note that the table body 11 has a guide groove 13B2 that slides and guides the slide pin 13A1 in a spiral shape, so that even if the urging force of the spring 13C is not applied, the table body 11 is moved away from the retracted position by the gravitational action. It is designed to return naturally to the use position. However, since the spring 13C is set, the table body 11 can be appropriately returned to the use position. Here, the guide groove 13B2 and the spring 13C that slide-guide the slide pin 13A1 respectively correspond to the “biasing structure” of the present invention.

  In summary, the table 10 of this embodiment has the following configuration. That is, the table 10 of the present embodiment includes a table main body 11 on which the object is placed, and a table moving device 10M that connects the table main body 11 to a state in which the table main body 11 can be moved with respect to the base (support base 4). The table moving device 10M is located between the use position positioned at the front of the seated person in a state where the table main body 11 can be used as a load and the retracted position where the table main body 11 is retracted forward and outward from the use position. It has a turning mechanism 13 that makes it turn, and a biasing structure (a guide groove 13B2 and a spring 13C) that biases the table body 11 toward the use position. Even if the table body 11 is pushed to the retracted position against the urging force of the urging structure (guide groove 13B2 and spring 13C), the force is released, so that the urging structure (guide groove 13B2 and The spring 13C) is returned to the use position by the urging force.

  With such a configuration, the urging force of the urging structure (the guide groove 13B2 and the spring 13C) can be achieved even when the table body 11 is moved from the use position to the retracted position by the turning mechanism 13. It becomes easy to be held in the use position. Therefore, the table main body 11 can be easily stabilized at the use position. Even if the table body 11 is pushed from the use position to the retracted position, the table body 11 is naturally returned to the use position by the urging force of the urging structure (guide groove 13B2 and spring 13C). The operation for returning can be made unnecessary.

  Further, the turning mechanism 13 is configured to raise the height position of the table body 11 by moving the table body 11 from the use position to the retracted position. With such a configuration, it is possible to make it difficult to interfere with obstacles such as the armrest 5 when the table body 11 is retreated. Moreover, since the height space from the seat surface of the seat 1 is increased by raising the height of the table main body 11, it is possible to make the passenger seat on the seat 1 more convenient.

  Further, the turning mechanism 13 includes a guide portion (fixed plate 13B) in which the support portion (movable plate 13A) that supports the table body 11 by the retreating movement of the table body 11 is inclined in the height direction while keeping the table body 11 in a horizontal posture. It slides along the guide shape (guide groove 13B2) and increases the height position of the table body 11. With this configuration, the table main body 11 can be moved between the use position and the retracted position on the front diagonally upper outer side while maintaining the horizontal posture in which the table main body 11 can function as an object.
