OBJECT OF THE INVENTION
An object of the present invention is to obtain a side table device for a vehicle which has a small operation angle of an operation member and is excellent in operability, based on the above-mentioned problem consciousness about a conventional device.
[0006]
SUMMARY OF THE INVENTION
The present invention relates to a fixed link fixed to a side portion of a vehicle seat; a table main body having one end pivotally attached to the upper side of the fixed link; and a first shaft pivotally attached to the free end of the table main body. An upper link; a lower link having one end pivotally attached to the lower side of the fixed link; and a third pivotally connecting the other end of the upper link and the other end of the lower link. A side table device for a vehicle, in which the table body is movable between a substantially horizontal use position and a substantially vertical storage position by rotating the upper link and the lower link. When rotating from the position to the use position, the upper link and the lower link rotate beyond the state where the first axis, the second axis, and the third axis are aligned, and the table body becomes substantially horizontal. In the same direction of the upper link and the lower link Provided stopper mechanism for restricting the rotation, the first axis coaxial, thereby enabling relative rotation between the one and the other rotation end against said upper link pivotally mounted an operating member, the operating member, When the table main body is in the use position, the upper body link is located at the one rotation end with respect to the upper link so that the swinging motion accompanying the table storing operation of the operating member is directly transmitted to the upper link. Further, when the table main body is moved from the use position to the storage position and the upper link is rotated, the operation member rotates relative to the upper link and moves from the one rotation end to the other. It is characterized by moving to the rotating end .
[0007]
According to this configuration, since the rotation angle of the operation member can be made smaller than the rotation angle of the upper link, the operability is improved.
[0008]
Specifically, the operation member can be constituted by a swing plate fixed to the first shaft and having an arc hole centered on the first shaft, and an operation lever fixed to the swing plate. And if the interlocking pin which fits in this circular arc hole is fixed to an upper link, relative rotation with an upper link and an operation member can be enabled by the simple structure of this circular arc hole and an interlocking pin.
[0009]
For example, the operation lever can be urged to rotate in a direction opposite to the table body storage direction, and the rotation end can be regulated by a contact position between a stopper provided on the operation lever and the lower surface of the table body. Then, the interlocking pin of the upper link is brought into contact with one end portion of the circular arc hole at the stopper position of the operation lever, and the rotation operation of the operation lever in the table body storage direction is directly transmitted to the upper link.
[0010]
When the upper link rotates in the table body storage direction, the rocker plate has a circular hole in which the interlocking pin of the upper link reaches the other rotation end of the circular hole, and then the operating lever is moved together with the upper link. If it is formed in such a length that it is pulled in a direction in contact with the lower surface of the table main body, the operation lever is not reliably stored in the lower surface of the table and protruded.
[0011]
By providing a torsion spring that pivots and urges the table main body in the direction of the use position at the pivot shaft portion of the table main body with the fixed link, the table main body can be moved more smoothly to the use position. Similarly, the second shaft, which is the pivot shaft of the fixed link and the lower link, is provided with a torsion spring that urges the lower link in the direction of the use position so that the table body can be easily moved to the locked position. Can be moved. Further, a holding mechanism for holding the table body in the storage position can be provided between the fixed link side and the table body side.

DETAILED DESCRIPTION OF THE INVENTION
As shown in FIG. 6, a pair of fixed links 12 having the same shape with different positions in the front and rear sides are fixed in parallel to a front seat (passenger seat or driver's seat) 11 of the vehicle. . A table body 14 is pivotally attached to the upper ends of the pair of fixed links 12 by a shaft 13 (see FIG. 1 and subsequent drawings). The table body 14 is long in the front-rear direction and has a width that substantially closes the gap between the left and right seats (driver seat and front passenger seat) when in the horizontal use position.
[0013]
A pair of upper links 15 are pivotally attached to the table main body 14 by a first shaft 16 so as to coincide with the positions of the pair of fixed links 12. The upper link 15 and the first shaft 16 are relatively rotatable. The pair of upper links 15 are connected by a connection plate 15c (FIG. 2). On the other hand, a lower link 18 is pivotally attached to each of the lower sides of the pair of fixed links 12 by a second shaft 17, and an upper end portion of the pair of lower links 18 and a lower end portion of the upper link 15 are respectively first. It is pivotally attached on a triaxial 19.
[0014]
The distance between the shaft 13, the first shaft 16, the second shaft 17, and the third shaft 19 is such that the table body 14 can be rotated and moved between a horizontal use position and a substantially vertical storage position. When the first shaft 16, the third shaft 19, and the second shaft 17 are aligned on a straight line, the table main body 14 is horizontally moved at a position where the third shaft 19 is rotated beyond the position where the first shaft 16, the third shaft 19 and the second shaft 17 are aligned. (See FIGS. 3 and 5). That is, in order to move the table main body 14 from the horizontal position to the storage position, the table main body 14 must be slightly raised from the horizontal position once (the free end is not pivoted up about the shaft 13) and moved to the storage position. I can't let you. When the third shaft 19 rotates beyond the position where the first shaft 16, the third shaft 19, and the second shaft 17 are aligned, and the table main body 14 becomes horizontal, the upper side made of a U-shaped channel material. The stopper edge 15a (FIGS. 3 and 5) at the lower end of the link 15 is in contact with the upper surface of the lower link 18 made of a U-shaped channel material, and the lower link 18 is further rotated (FIGS. 3 and 5). (Clockwise rotation of 5) is prevented. That is, the stopper edge 15a and the lower link 18 constitute a stopper mechanism.
[0015]
The shaft 13 is provided with a torsion spring 20 that urges the table main body 14 to rotate in the use position direction around the shaft 13, and the second shaft 17 has the lower link 18 in the use position direction (see FIG. 3). A torsion spring 21 is provided which is urged to rotate in the clockwise direction in FIG.
[0016]
The first shaft 16 is rotatably supported by a pair of brackets 14a provided on the table main body 14, and a swing plate 22a is fixed to the projecting end from one bracket 14a by welding. An operation lever 22b extending substantially parallel to the first shaft 16 is welded and fixed to the swing plate 22a at an eccentric position with respect to the first shaft 16, and the tip of the operation lever 22b is bent at a substantially right angle. The applied force portion 22c is configured.
[0017]
The swing plate 22a of the operating member 22 is formed with an arc hole 22d with the first shaft 16 as the center, and is parallel to the first shaft 16 which is erected and fixed to the upper link 15 in the arc hole 22d. An interlocking pin 15b is fitted. Therefore, the operation member 22 and the upper link 15 can be relatively rotated within the range of the effective length of the arc hole 22d.
[0018]
Further, the operating member 22 is counteracted in FIGS. 3 and 5 by a tension coil spring 23 stretched between a spring hooking protrusion 22f formed on the swing plate 22a and a spring hooking protrusion 14b formed on the bracket 14a. It is urged to rotate clockwise. A stopper 22 s that is in contact with the lower surface of the table main body 14 and restricts the rotating end against the force of the tension coil spring 23 is fixed to the first shaft 16 by welding. When the table main body 14 is in the use position, the interlocking pin 15b of the upper link 15 is set so as to contact the lower end of FIGS. 3 and 5 of the arc hole 22d. Accordingly, the operating member 22 (the stopper 22s and the circular hole 22d thereof) and the interlocking pin 15b of the upper link 15 also have a stopper mechanism (the lower link 18 is shown in FIGS. 3 and 5 to hold the table body 14 in the use position. (Stopper mechanism for preventing clockwise rotation from the position).
[0019]
A gripping tool 24 (FIG. 1, FIG. 2, FIG. 5) having a pair of elastic gripping lips 24 a is fixed to the connection plate 12 a that connects the pair of fixed links 12. The gripper 24 grips the first shaft 16 of the table main body 14 rotated to the storage position, and holds the table main body 14 in the storage position against the force of the torsion springs 20 and 21.
[0020]
3 and 5, the side table device having the above-described configuration is arranged on the lower side by the contact between the stopper edge 15a of the upper link 15 and the lower link 18 and the contact between the interlocking pin 15b and the circular arc hole 22d. The rotation of the link 18 in the clockwise direction in the figure is prevented, and even when a downward force is applied to the table body 14, the counterclockwise turning force in the figure does not act on the lower link 18. Therefore, the table main body 14 can be used in a stable horizontal state.
[0021]
On the other hand, when storing the table main body 14, the force applying portion 22 c of the operation member 22 is lifted. Then, due to the relationship between the arc hole 22d and the interlocking pin 15b, the upper link 15 rotates clockwise together with the operation member 22, and the lower link 18 rotates counterclockwise. At this time, the third shaft 19 once reaches a state in which the first shaft 16, the third shaft 19, and the second shaft 17 are positioned on a straight line (that is, the end of the table body 14 on the first shaft 16 side is once. Then, the table main body 14 rotates about the shaft 13 in the storing direction. When the table main body 14 reaches the storage position, the gripping tool 24 grips the first shaft 16 and locks it to the storage position.
[0022]
While the table main body 14 reaches the storage position from the use position, the upper link 15 rotates relative to the operation member 22 by the effective length of the arc hole 22d. When the interlocking pin 15b comes into contact with the other rotation end of the arc hole 22d, the operation member 22 rotates together with the upper link 15 while bending the tension coil spring 23 thereafter. That is, when the upper link 15 rotates in the table main body storage direction, the arc hole 22d reaches the other rotation end of the arc hole 22d, and then the operation lever 22c moves together with the upper link 15. It is formed in a length that is pulled in a direction in contact with the lower surface of the table body. For this reason, the rotation angle of the operation member 22 can be made smaller than the rotation angle of the upper link 15 (table body 14), and the operation lever 22b is provided on the lower surface of the table body 14 as shown in FIG. Can be stored.
[0023]
In other words, when the table body 14 is moved from the use position to the storage position, the minimum operation angle that must be given to the upper link 15 is that the first axis 16, the second axis 17, and the third axis 19 are in a straight line. It is an angle that rotates beyond the position lined up. Thereafter, the table body 14 can be stored by applying a force in the storing direction, and therefore the length of the circular arc hole 22d can be increased within a range in which this action can be obtained.
[0024]
In order to rotate the table main body 14 from the stored state to the use state, it is only necessary to apply a force in the use position direction to the table main body 14 to disengage the first shaft 16 from the gripper 24. The table body 14 and the lower link 18 are rotated in the use position direction by the force of the torsion springs 20 and 21, and the first shaft 16, the third shaft 19, and the second shaft 17 eventually reach a straight line. When the end of the table body 14 on the first shaft 16 side further rises from this state, the stopper edge 15a of the upper link 15 and the lower link 18 come into contact with each other, and the stopper works. During this time, the stopper 22s of the operating member 22 contacts the lower surface of the table main body 14 and its rotating end is regulated, and the interlocking pin 15b contacts one end of the circular arc hole 22d, and the stopper works similarly.
[0025]
In the above embodiment, the stopper mechanism at the use position of the table main body 14 exists at the two positions of the stopper edge 15a and the lower link 18, the arc hole 22d and the interlocking pin 15b, but only one of them may be used. When only the stopper mechanism by the stopper edge 15a and the lower link 18 is used, the rotation biasing direction of the operation member 22 is reversed from the above embodiment, and the interlocking pin 15b is turned into the circular arc hole 22d by the rotation biasing force. You may make it contact | abut to the edge part.
