With reference to FIGS. 8 to 13, the internal structure of the vehicle table 1 is performed when the article holding portion 40 is switched between the stored state and the expanded state in conjunction with the rotation of the table portion 30. The operation will be described. 8 to 13 are schematic views showing only the first table rotation shaft 12, the cam mechanism 43, the translational holding wall 42, the link mechanism 44, and the lid portion 41 of the vehicle table 1. Further, FIGS. 8 to 13 are described with the first mounting surface 31 fixed horizontally for the sake of explanation.

First, with reference to FIGS. 8 to 10, a state in which the translational holding wall 42 moves between the storage position and the holding position as the table body 20 rotates will be described. 8 to 10 are front views of the vehicle table 1 as viewed from the direction along the table rotation shaft 11.

As shown in FIG. 8, when the table body 20 is in the folded position, the protrusion of the cam mechanism 43 is located on the lower side in the drawing. Since the recess 42A of the translational holding wall 42 is engaged with the convex portion 43B of the cam mechanism 43, the translational holding wall 42 is in the storage position.

As shown in FIG. 9, when the table body 20 rotates from the folded position to the unfolded position, the table rotating shaft 11 fixed to the mounting member 10 rotates relative to the article holding portion 40. do. When the first table rotation shaft 12 rotates relative to the table body 20, the cam mechanism 43 rotates due to the engagement between the first tooth portion 12A and the second tooth portion 43A. Due to the rotation of the cam mechanism 43, the convex portion 43B of the cam mechanism 43 moves upward in the drawing. The translational holding wall 42 moves from the storage position to the holding position in accordance with the rotation of the cam mechanism 43.

As shown in FIG. 10, when the table body 20 is in the unfolded position, the convex portion 43B of the cam mechanism 43 is located at the upper side in the drawing, and the translation holding wall 42 is in the unfolded position. The translational holding wall 42 moves from the storage position to the holding position in conjunction with the rotation of the table body 20 from the folding position to the unfolding position.

When the table body 20 rotates from the unfolded position to the folded position, the translational holding wall 42, the cam mechanism 43, and the table rotating shaft 11 perform the above-described operations in the reverse directions from FIGS. 10 to 8. .. Then, the translational holding wall 42 moves from the holding position to the storage position in conjunction with the rotation of the table body 20 from the unfolded position to the folded position.

That is, the first table rotation shaft 12 and the cam mechanism 43 receive the rotation from the folding position to the unfolding position of the table portion 30 to bring out the translational holding wall 42 from the storage position to the holding position, and then the table portion 30 It functions as a first transmission mechanism that returns the translational holding wall 42 from the holding position to the storage position in response to rotation from the unfolding position to the folding position.

Next, with reference to FIGS. 11 to 13, a state in which the article holding portion 40 is switched from the stored state to the expanded state as the table body 20 rotates will be described. 11 to 13 are side views of the vehicle table 1 as viewed from the direction along the rotation axis of the lid 41. Further, in FIGS. 11 to 13, the end faces of the table portion 30 are shown by alternate long and short dash lines.

As shown in FIG. 11, when the table body 20 is in the folded position, the article holding portion 40 is stored. Further, when the article holding portion 40 is in the stored state, the translational holding wall 42 is in the storage position, and the lid portion 41 is in the closed position. At this time, the translational holding wall 42 does not project from the first mounting surface 31 of the table portion 30, and the outer surface 41A included in the lid portion 41 and the first mounting surface 31 are continuous. FIG. 11 corresponds to the vehicle table 1 shown in FIG.

As shown in FIG. 12, when the table body 20 rotates from the folding position to the unfolding position, the translational holding wall 42 moves from the storage position to the holding position. By moving the translation holding wall 42 from the storage position to the holding position, the lid portion 41 connected to the translation holding wall 42 by the link mechanism 44 rotates from the closed position to the open position.

As shown in FIG. 13, when the table body 20 is in the unfolded position, the article holding portion 40 is in the unfolded state. When the article holding portion 40 is in the unfolded state, the translational holding wall 42 is in the holding position, and the lid portion 41 opens from the closed position in conjunction with the rotation of the table body 20 from the folded position to the unfolded position. Rotate towards the position. FIG. 12 corresponds to the vehicle table 1 shown in FIG.

At this time, the cam mechanism 43 functions as a connecting means for connecting the table rotating shaft 11 and the article holding portion 40. Then, in conjunction with the rotation of the table body 20 from the folded position to the unfolded position, the article holding portion 40 switches from the stored state to the unfolded state. FIG. 13 corresponds to the vehicle table 1 shown in FIG.

Further, the article holding portion 40 in the expanded state projects by the amount of protrusion P with respect to the first mounting surface 31 of the table portion 30.
When the table body 20 rotates from the unfolded position to the folded position, the translational holding wall 42, the link mechanism 44, and the lid 41 perform the above-described operations in the reverse directions from FIGS. 13 to 11. Then, in conjunction with the rotation of the table body 20 from the unfolded position to the folded position, the lid portion 41 rotates from the open position to the closed position, and the article holding portion 40 is stored from the unfolded state. Switch to the state.

That is, the link mechanism 44 rotates the lid 41 from the closed position to the open position in response to the movement of the translational holding wall 42 from the storage position to the holding position, and from the holding position of the translational holding wall 42 to the storage position. It functions as a second transmission mechanism that returns the lid portion 41 from the open position to the closed position in response to the movement of the lid portion 41.

As described above, according to the above-described configuration, the following effects can be obtained.
(1) The vehicle table 1 is configured to be able to appear and disappear with respect to the first mounting surface 31 between the storage position and the holding position which is a position protruding from the first mounting surface 31 from the storage position. A holding wall 42 is provided. Therefore, the vehicle table 1 can stably hold the article in the unfolded position while securing a space that can be used in the folded position.

(2) The vehicle table 1 receives the rotation of the table portion 30 from the folded position to the unfolded position to bring out the translation holding wall 42, and receives the rotation of the table portion 30 from the unfolded position to the folded position. A first transmission mechanism for returning the translational holding wall 42 from the holding position to the storage position is provided. Therefore, the translational holding wall 42 is displaced to a position suitable for use of the table portion 30 by performing an operation for rotating the table portion 30 between the unfolded position and the folded position. It is possible to improve operability.

(3) The second mounting surface 32A is lower than the first mounting surface 31, and the translational holding wall 42 appears and disappears at the boundary between the first mounting surface 31 and the second mounting surface 32A. Therefore, the position of the translational holding wall 42 with respect to the second mounting surface 32A is the position of the translational holding wall 42 with respect to the first mounting surface 31 by the amount of the step between the first mounting surface 31 and the second mounting surface 32A. Higher than. Then, since the article such as the beverage cup placed on the second mounting surface 32A is held by the translational holding wall 42 at a higher position with respect to the second mounting surface 32A, it is placed on the first mounting surface 31. Posture is easier to stabilize than when it is done.

(4) The vehicle table 1 is held in parallel with a lid portion 41 rotatably supported between a closed position covering the second mounting surface 32A and an open position for opening the second mounting surface 32A. A second transmission mechanism for rotating the lid 41 in response to the movement of the wall 42 is provided. Therefore, when the table portion 30 is displaced to the unfolded position, the translational holding wall 42 is displaced to the holding position, and the second mounting surface 32A closed by the lid portion 41 is opened accordingly. By performing the operation for rotating the table portion 30 to the unfolded position in this way, the translation holding wall 42 and the lid are positioned at positions suitable for use of the first mounting surface 31 and the second mounting surface 32A. Since the portion 41 is displaced, the operability of the vehicle table 1 can be further improved.

(5) The lid portion 41 has a shape in which the article placed on the second mounting surface 32A faces the translation holding wall 42 in the open position and is held between the translation holding wall 42 and the lid portion 41. Therefore, the vehicle table 1 can hold the article more stably.

(6) The lid portion 41 includes an outer surface continuous with the table portion 30 in the closed position. Therefore, it is possible to enhance the design of the vehicle table 1 when the table body 20 is in the folded position.

(7) The vehicle table 1 has a first table rotation shaft 12 that rotatably supports the table portion 30, and a translational holding wall for rotating the table portion with respect to the first table rotation shaft 12 with respect to the mounting surface. It is provided with a cam mechanism 43 that converts the translation into the translation of 42. Therefore, it is possible to easily switch from the storage position of the translational holding wall 42 to the holding position.

(8) The second transmission mechanism converts the movement of the translational holding wall 42 from the storage position to the holding position into the opening of the lid 41, and the movement of the translational holding wall 42 from the holding position to the storage position is the lid. It is a link mechanism that converts to the closure of. Therefore, it is possible to easily open and close the lid portion.

The above-described embodiment can be modified and executed as follows.
The first transmission mechanism receives the rotation of the table portion 30 from the folded position to the unfolded position to bring out the translation holding wall 42, and receives the rotation of the table portion 30 from the unfolded position to the folded position to hold the translation. The configuration is not limited to the configuration in which the wall 42 is returned from the holding position to the storage position.

In the above embodiment, as shown in FIG. 14, the concave portion 42A has a size such that the convex portion 43B is aligned with each other along the moving direction of the translational holding wall 42, so that when the table portion 30 rotates. , The translational holding wall 42 moves following the rotation of the cam mechanism 43.

On the other hand, for example, as shown in FIG. 15, the translational holding wall 42 may have a configuration in which a notch 42B is formed. The convex portion 43B included in the cam mechanism 43 engages with the notch 42B when the convex portion 43B moves upward. When the convex portion 43B moves downward, it separates from the notch 42B. In addition, in FIGS. 15 to 18, as a reference of the position of the moving translation holding wall 42, the plane including the second mounting surface 32A is shown by a alternate long and short dash line.

When the table portion 30 is in the folding position and the translational holding wall 42 is in the storage position (FIG. 15A), when the table portion 30 rotates from the folding position to the unfolding position, the cam mechanism 43 rotates. The convex portion 43B lifts the translational holding wall 42. Therefore, the translational holding wall 42 moves from the storage position to the holding position (FIG. 15B). Further, when the table portion 30 rotates from the folded position to the unfolded position, the cam mechanism 43 rotates so that the convex portion 43B is separated from the notch 42B (FIG. 15 (c)). Therefore, the translational holding wall 42 stays in the holding position. The user of the vehicle table manually pushes in the translational holding wall 42 to move it from the holding position to the storage position (FIG. 15 (d)).

According to the above-described configuration, the first transmission mechanism receives the rotation of the table portion 30 from the folding position to the unfolding position and moves the translational holding wall 42 from the storage position to the holding position. On the other hand, when the table portion 30 rotates from the unfolded position to the folded position, the parallel holding wall 42 does not move.

Further, for example, as shown in FIG. 16, the translational holding wall 42 may have a configuration in which a concave portion 42C having a size that allows the convex portion 43B to move along the moving direction of the translational holding wall 42 is formed. .. The recess 42C extends from the position of the convex portion 43B when the table portion 30 is in the folded position to the position of the convex portion 43B when the table portion 30 is in the folded position when the translation holding wall 42 is in the storage position. It is formed.

When the table portion 30 is in the folded position and the translational holding wall 42 is in the stored position (FIG. 16A), when the table portion 30 rotates from the folded position to the unfolded position, the cam mechanism 43 rotates. However, since the convex portion 43B moves in the concave portion 42C, the convex portion 43B does not engage with the concave portion 42C, and the translational holding wall 42 stays in the storage position (FIG. 16B). The user of the vehicle table manually pulls out the translational holding wall 42 and moves the translational holding wall 42 from the storage position to the holding position (FIG. 16 (c)). When the table portion 30 rotates from the unfolded position to the folded position, the cam mechanism 43 rotates. At this time, since the convex portion 43B engages with the concave portion 42C and pushes down the translational holding wall 42, the translational holding wall 42 moves from the holding position to the storage position (FIG. 16D).

According to the above-described configuration, the first transmission mechanism moves the translational holding wall 42 from the holding position to the storage position in response to the rotation of the table portion 30 from the unfolded position to the folded position. On the other hand, when the table portion 30 rotates from the folded position to the unfolded position, the parallel holding wall 42 does not move.

That is, the first transmission mechanism receives the rotation from the folding position of the table portion 30 to the unfolding position to bring out the translational holding wall 42 from the storage position to the holding position, and moves the table portion 30 from the unfolding position to the folding position. It may be configured to perform at least one of returning the translational holding wall 42 from the holding position to the storage position by receiving rotation. Even with the above-described configuration, it is possible to obtain an effect according to the above (2).

From the viewpoint of improving the operability of the vehicle table 1, the translation holding wall 42 is exposed in response to the rotation of the table portion 30 from the folded position to the unfolded position, and the folded position is taken from the unfolded position of the table portion 30. It is preferable that the translational holding wall 42 is returned from the holding position to the storage position in response to the rotation to.

Further, as shown in FIG. 17, the recess 42D and the slope portion 42E may be formed on the translational holding wall 42. The slope portion 42E is formed so that a convex portion 43B that has moved in the direction in which the second mounting surface 32A is located can ride on the edge of the concave portion 42D. At this time, the vehicle table 1 further includes an elastic member that applies an urging force to the cam mechanism 43 so that the convex portion 43B is pressed toward the parallel holding wall 42, and the cam mechanism 43 is a rotation shaft of the table portion 30. It is configured to be displaceable in the direction along.

When the table portion 30 is in the folding position and the translational holding wall 42 is in the storage position (FIG. 17A), when the table portion 30 rotates from the folding position to the unfolding position, the cam mechanism 43 rotates. The convex portion 43B lifts the translational holding wall 42. Therefore, the translational holding wall 42 moves from the storage position to the holding position (FIG. 17B). Further, when the table portion 30 rotates from the folded position to the unfolded position, the cam mechanism 43 rotates so that the convex portion 43B gets on the slope portion 42E (FIG. 17 (c)) and separates from the translation holding wall 42. (Fig. 17 (d)). Therefore, the translational holding wall 42 stays in the holding position. The user of the vehicle table 1 manually pushes in the translational holding wall 42 to move it from the holding position to the storage position (FIG. 17 (e)).

According to the above-described configuration, when the convex portion 43B gets on the slope portion 42E, a force resisting the urging force is applied to the cam mechanism 43, and the cam mechanism 43 must move along the rotation axis of the table portion 30. Therefore, as compared with the configuration shown in FIG. 15, the force required to rotate the table portion 30 from the unfolded position to the folded position is increased, and it is possible to suppress an unintended operation of the table portion 30. Become.

Further, as shown in FIG. 18, the translational holding wall 42 is formed with a recess 42F having a size in which the convex portion 43B can move along the moving direction of the translational holding wall 42, and the recess 42F has a recess 42F. The structure may be such that the slope portion 42G is formed. The slope portion 42G is formed so that the convex portion 43B that has moved in the direction in which the first mounting surface 31 is located can ride in the concave portion 42F. At this time, the vehicle table 1 further includes an elastic member (not shown) that applies an urging force to the cam mechanism 43 so that the convex portion 43B is pressed toward the parallel holding wall 42, and the cam mechanism 43 is provided with the table portion 30. It is configured to be displaceable in the direction along the rotation axis of.

When the table portion 30 is in the folded position and the translational holding wall 42 is in the stored position (FIG. 18A), when the table portion 30 rotates from the folded position to the unfolded position, the cam mechanism 43 rotates. However, since the convex portion 43B moves in the concave portion 42F while riding on the slope portion 42G (FIG. 18 (b)), the convex portion 43B does not engage with the concave portion 42F, and the translational holding wall 42 stays in the storage position. (Fig. 18 (c)). The user of the vehicle table manually pulls out the translational holding wall 42 and moves the translational holding wall 42 from the storage position to the holding position (FIG. 18 (d)). When the table portion 30 rotates from the unfolded position to the folded position, the cam mechanism 43 rotates. At this time, since the convex portion 43B engages with the concave portion 42F and pushes down the translational holding wall 42, the translational holding wall 42 moves from the holding position to the storage position. (FIG. 18 (e)).

According to the above-described configuration, when the convex portion 43B gets on the slope portion 42G, a force resisting the urging force is applied to the cam mechanism 43, and the convex portion 43B must be displaced along the rotation axis of the table portion 30. Therefore, as compared with the configuration shown in FIG. 16, the force required to rotate the table portion 30 from the folding position to the unfolding position becomes larger, and it is possible to suppress unintentional operation of the table portion 30. Is possible.

The engagement between the first tooth portion 12A formed on the first table rotation shaft 12 and the second tooth portion 43A included in the cam mechanism 43 may be configured by a ratchet mechanism. At this time, the force is transmitted from the first tooth portion 12A to the second tooth portion 43A only in either the rotation from the folding position to the unfolding position or the rotation from the unfolding position to the folding position of the table portion 30. , The cam mechanism 43 rotates.

In the case where the force is transmitted from the first tooth portion 12A to the second tooth portion 43A only when the table portion 30 rotates from the folded position to the unfolded position, and the translational holding wall 42 protrudes from the storage position to the holding position, the table portion When the 30 rotates from the unfolded position to the folded position, no force is transmitted from the first tooth portion 12A to the second tooth portion 43A, and the translational holding wall 42 stays in the holding position. When the translational holding wall 42 moves from the holding position to the storage position, the force from the second tooth portion 43A to the first tooth portion 12A is not transmitted, so that the user of the vehicle table 1 manually performs the translational holding wall. The 42 can be returned from the holding position to the storage position.

On the other hand, in the case where the force is transmitted from the first tooth portion 12A to the second tooth portion 43A only when the table portion 30 rotates from the folding position to the unfolding position, and the translational holding wall 42 returns from the holding position to the storage position. When the table portion 30 rotates from the folded position to the unfolded position, no force is transmitted from the first tooth portion 12A to the second tooth portion 43A, and the translational holding wall 42 stays in the storage position. Since the force from the second tooth portion 43A to the first tooth portion 12A is not transmitted when the translational holding wall 42 protrudes from the storage position to the holding position, the user of the vehicle table 1 manually stores the translational holding wall 42 in the storage position. Can be pulled out to the holding position.

Even with the above-described configuration, the first transmission mechanism receives the rotation of the table portion 30 from the folding position to the unfolding position to bring out the translational holding wall 42 from the storage position to the holding position, and the table portion 30. The translation holding wall 42 is returned from the holding position to the storage position by receiving the rotation from the unfolding position to the folding position, and the effect according to the above (2) can be obtained.

The vehicle table 1 is not limited to a configuration in which the translational holding wall 42 functions as a side holding wall for holding an article placed on the second mounting surface 32A from the side. The vehicle table 1 may have, for example, a configuration in which the lid portion 41 is provided with a side holding wall. The side holding wall included in the lid portion 41 is arranged so as to be continuous from the first mounting surface in the closed position to cover the second mounting surface, and to protrude from the first mounting surface in the open position. The second mounting surface is opened. At this time, the translational holding wall 42 may function together with the first table rotation shaft 12, the cam mechanism 43, and the link mechanism 44 as a transmission mechanism for moving the lid portion 41 in response to the rotation of the table portion 30. The transmission mechanism receives the rotation of the table portion 30 from the folded position to the unfolded position to move the lid portion 41 from the closed position to the open position, and receives the rotation from the unfolded position to the folded position to receive the lid. At least one of returning the portion 41 from the open position to the closed position may be performed. Further, the transmission mechanism is not limited to a configuration that functions by the first table rotation shaft 12, the translational holding wall 42, the cam mechanism 43, and the link mechanism 44, and converts the rotation of the table portion 30 as the movement of the lid portion 41. It may be a mechanical mechanism. Even with the above-described configuration, an effect according to the above (1) can be obtained.
