  However, in the above-described conventional technology, when a heavy article is placed on the table body 150 when the table device 104 is in a usable state, the two free ends 174 side of the spring rod 170 may be bent in a direction approaching each other. It was. If bent in this way, the holding on both free ends 174 side of the spring rod 170 is switched from one end 142a to the other end 142b of the pair of cam surfaces 142, so that the base end 172 of the spring rod 170 is a long hole 154. Had to move. Therefore, the table device 104 may be switched from the usable state to the stored state. Therefore, it has been impossible to use a heavy article on the table body 150.

  An object of the present invention is to provide a table device for a vehicle seat that can be used even when a heavy article is placed on a table body in a usable state.

The present invention is for achieving the above object, and is configured as follows.
The invention according to claim 1 is assembled to the frame of the seat cushion or the seat back and has a base frame having a pair of cam surfaces formed in a substantially arc shape, hinged to the base frame, and has a long hole. The table body and base end can move through the long hole, both free ends are hinged to the base frame, and both free ends can be turned along a pair of cam surfaces by hinge connection A substantially U-shaped spring rod. Each one end or each other end of the pair of cam surfaces can hold both free end sides of the spring rod. When both free ends of the spring rod are held at one end of the pair of cam surfaces, the base end of the spring rod can hold the table main body so that the table main body can be used in a substantially horizontal state. In addition, when both free ends of the spring rod are held at the other ends of the pair of cam surfaces, the base end of the spring rod is attached to the table main body so that the table main body is folded along the vehicle seat. It can be retained. A lever that locks the movement of the proximal end of the spring rod with respect to the long hole when the table device itself is ready for use is assembled to the table body. The lever is formed with a concave groove on the outer peripheral surface into which the base end of the spring rod can enter when a heavy load is applied along the direction in which the article is placed on the table body in a usable state.

According to the first aspect of the present invention, when the movement of the base end of the spring rod is restricted, the holding of both free ends of the spring rod with respect to the respective one ends of the pair of cam surfaces can be restricted (locked). Therefore, it is possible to restrict (lock) switching of the table device from the usable state to the housed state. Therefore, even if a heavy article is placed on the table body in the usable state, the table device does not switch from the usable state to the stored state. As a result, even if a heavy article is placed on the table body in the usable state, it can be used. According to the first aspect of the present invention, when a large load is applied to the table body in the usable state, the base end of the spring rod that falls down due to the applied large load enters the concave groove of the lever. Therefore, the rotation of the lever is restricted thereafter. As a result, even if the lever is operated in a state where a large load is applied to the table body, the operation is not accepted by the lever, so that the table body can be prevented from being folded. According to a second aspect of the present invention, there is provided the vehicle seat table device according to the first aspect, wherein the lever is composed of a thin plate member. The load acting on the concave groove of the lever from the proximal end of the spring rod as the proximal end of the spring rod enters the concave groove of the lever is set so as to substantially follow the axial center in the longitudinal direction of the lever. Moreover, invention of Claim 3 is the table apparatus of the vehicle seat in any one of Claims 1-2, Comprising: A long hole is formed in linear form.

The concave surface is set to be orthogonal to the entering direction when the proximal end of the spring rod enters the concave groove.

According to the fourth aspect of the present invention, it is possible to prevent the base end of the spring rod that has entered the concave groove from sliding off the concave surface and falling off the concave groove. Therefore, the rotation of the lever is surely restricted. As a result, even if the lever is operated while a large load is applied to the table body, it is possible to reliably prevent the base end of the spring rod from moving, so that the table body can be folded. Can be prevented.

According to a fifth aspect of the present invention, there is provided the vehicle seat table device according to the fourth aspect , wherein the lever is hinged to the table body. When the base end of the spring rod enters the concave groove, the three points of the center of the base end of the spring rod, the contact point between the concave surface of the concave groove and the base end of the spring rod, and the center of the lever hinge are: It is set to be on the same straight line.

According to the fifth aspect of the present invention, it is possible to reliably prevent the base end of the spring rod that has entered the concave groove from slipping off the concave surface and falling off the concave groove. Therefore, the rotation of the lever is more reliably regulated. As a result, even if the lever is operated while a large load is applied to the table body, it is possible to more reliably prevent the base end of the spring rod from moving. It can be prevented more reliably.

The invention according to claim 6 is the vehicle seat table device according to any one of claims 1 to 3, wherein the shape of the cross section of the base end of the spring rod and the shape of the cross section of the concave groove Are formed to correspond.

  Hereinafter, the form for implementing this invention is demonstrated using FIGS. In the following description, “second seat 1 on the right side of a minivan having three rows of seats” (hereinafter simply referred to as “second seat 1”) will be described as an example of “vehicle seat”. Further, in the following description, “up”, “down”, “front”, “back”, “left”, and “right” are the top, bottom, front, back, left, right directions described in the above-described drawings, that is, the second seat inside the minivan The directions of up, down, front, back, left, and right when the state where 1 is arranged are shown.

  First, the configuration of the second sheet 1 will be described with reference to FIG. This second seat 1 is of a single seat independent type, and mainly comprises a seat cushion 2 having an ottoman 2a and a seat back 3 having a headrest 3a.

  The seat cushion 2 mainly includes a cushion frame 10 formed in a substantially rectangular frame shape from a left side frame 12, a right side frame, a front frame, and a rear frame (all not shown), and the cushion frame 10 It is comprised from the cushion pad 14 assembled | attached so that it may cover, and the cushion cover 16 which covers the surface of this cushion pad 14 (refer FIG. 4).

  Returning to FIG. 1, a left cushion shield 20 and a right cushion shield 22 are assembled to the outer sides of the left side frame 12 and the right side frame of the seat cushion 2, respectively. Thereby, since the inside of the seat cushion 2 can be blinded, the designability of the second seat 1 can be improved. A table device 4 is assembled to the left side of the seat cushion 2.

  Here, the table device 4 will be described in detail with reference to FIGS. 1 to 5. The table device 4 mainly includes a base frame 30, a table body 50, and a spring rod 70. Below, these base frame 30, the table main body 50, and the spring rod 70 are demonstrated separately.

  First, the base frame 30 will be described. The base frame 30 is composed of a metal member that is bent in a substantially crank shape so as to form the skeleton of the table device 4. The surface of the base frame 30 on the second sheet 1 side (the surface facing the second sheet 1) is covered with a resin shield 32. Thereby, since the base frame 30 can be blinded from a passenger seated on the second seat 1 (hereinafter simply referred to as “occupant”), the design of the table device 4 can be improved.

  A pair of hinge brackets 34 made of metal members are fastened to the tip (upper end) 30a of the base frame 30, respectively. This fastening is performed by a bolt (not shown) and a nut N1, respectively. The hinge bracket 34 is formed with a through hole 34a into which a later-described hinge pin P1 can be inserted. A resin cam member 40 having a pair of cam surfaces 42 is fastened to the base frame 30. This fastening is performed at four locations by bolts (not shown) and nuts N2.

  The cam surface 42 is formed so as to have a substantially arcuate raised portion 42c between one end 42a (upper end) and the other end 42b (lower end) (see FIG. 3). That is, one end 42a and the other end 42b of the cam surface 42 are formed so as to form a recess with respect to the raised portion 42c. If formed in this way, both free ends 74 side of the spring rod 70 (slightly closer to the base end 72 than the free end 74) due to the reaction force of bending acting on both free ends 74 of the spring rod 70 described later. Can be held by each one end 42a or each other end 42b of the pair of cam surfaces 42.

  Each end 42a of the pair of cam surfaces 42 is formed so that the spring rod 70 faces upward when the one end 42a itself holds both free ends 74 of a spring rod 70 described later. . On the other hand, when the other ends 42b of the pair of cam surfaces 42 hold the other free ends 74 side of the spring rods 70 described later on the other ends 42b themselves, the spring rods 70 are lowered. It is formed to face. The base frame 30 is configured in this way.

  Next, the table body 50 will be described. The table main body 50 is formed of a resin member formed in a substantially rectangular shape so as to have a placement surface 50a on which an article (not shown) can be placed. A pair of guides 52 are formed on the table body 50. The guide 52 is formed with a long hole 54 through which a base end 72 of a spring rod 70 described later can move.

  A pair of hinge brackets 56 are integrally formed at one end of the table body 50. The hinge bracket 56 is formed with a through hole 56a into which a later-described hinge pin P1 can be inserted. The through holes 56a of the pair of hinge brackets 56 of the table main body 50 and the through holes 34a of the pair of hinge brackets 34 of the base frame 30 correspond to each other so that the hinge pins P1 can be inserted therein (match). To be).

  Further, on the back side of the table body 50 (the surface opposite to the placement surface 50a), a lever 60 having one end forming an operation portion 60a and the other end forming a lock portion 60b is rotatable via a hinge pin 62. (See FIGS. 4 to 5). For convenience of explanation, the center of the hinge pin 62 is referred to as “center C”. At this time, a torsion spring (not shown) having one end hooked to the table body 50 and the other end hooked to the lever 60 is inserted into the hinge pin 62.

  Thereby, when the table apparatus 4 is in a usable state to be described later, the table main body 50 is controlled so that the lock portion 60b regulates the movement of the base end 72 of the spring rod 70 in the pair of long holes 54 of the table main body 50. On the other hand, the lever 60 can be biased. The lock portion 60b of the lever 60 is formed with a concave groove 66 into which the base end 72 of the spring rod 70 can enter when a large load is applied to the table main body 50 in a usable state described later.

  A planar concave surface 66 a is formed in the concave groove 66. The concave surface 66a is set so as to be orthogonal to the entering direction when the base end 72 of the spring rod 70 enters the concave groove 66 (see FIG. 12). Note that a rubber 58 for preventing a hitting sound on the table body 50 when the lever 60 on which the operation unit 60a is operated is returned by the urging force of the torsion spring is fastened to the back side of the table body 50. . The table body 50 is configured as described above.

  Next, the spring rod 70 will be described. The spring rod 70 is composed of a substantially U-shaped metal member having a circular cross section. Both free ends (substantially U-shaped tips) 74 of the spring rod 70 are bent so as to face away from each other. For convenience of explanation, the center of the base end 72 of the spring rod 70 is referred to as “center A” (see FIG. 5). The spring rod 70 is configured in this way.

  Next, a structure for assembling the base frame 30, the table body 50, and the spring rod 70 described above will be described. Hinge pins P <b> 1 are inserted into the through holes 34 a of the pair of hinge brackets 34 of the base frame 30 and the through holes 56 a of the pair of hinge brackets 56 of the table body 50, respectively. Thereby, the table main body 50 can be rotated around an axis whose axial direction is the front-rear direction with respect to the base frame 30.

  An engagement claw P1a is formed on the outer peripheral surface of the inserted hinge pin P1 (see FIG. 2). Thereby, it is possible to prevent the inserted hinge pin P1 from falling out of the through holes 34a and 56a. Further, the base end (substantially U-shaped base) 72 of the spring rod 70 is hooked so as to be able to move both elongated holes 54 formed in the table body 50.

  On the other hand, both free ends (substantially U-shaped tips) 74 of the spring rod 70 are hinged to the cam member 40. Thereby, the spring rod 70 can be rotated with respect to the cam member 40. The hinge coupling is performed in a state where the free ends 74 are bent in a direction approaching each other by the pair of cam surfaces 42 of the cam member 40. Therefore, as described above, due to the reaction force of the bending acting on both free ends 74 of the spring rod 70, the both free ends 74 side of the spring rod 70 is connected to each end 42a of the pair of cam surfaces 42 or each other. It can be held at the end 42b.

  As already described, when both the free ends 74 of the spring rod 70 are held at the respective one ends 42a of the pair of cam surfaces 42 of the cam member 40, the spring rod 70 faces upward. Therefore, the base end 72 of the spring rod 70 presses the inner surfaces of the long holes 54 of the table body 50 so that the table body 50 is substantially horizontal. Therefore, the table main body 50 can be held in a usable state that is substantially horizontal. Thereby, the article can be used by being placed on the placement surface 50 a of the table body 50.

  At this time, since the base end 72 of the spring rod 70 also presses the inner surface of each end 54a of the long holes 54 of the table main body 50, it is possible to prevent the table main body 50 held in a usable state from rattling. At this time, as already described, the movement of the base end 72 of the spring rod 70 in both the long holes 54 of the table body 50 is restricted by the lock portion 60b. Thereby, when the table apparatus 4 is in a usable state, the table main body 50 can be locked with respect to the base frame 30, so that a heavy article can be placed on the placement surface 50a of the table main body 50.

  The base frame 30, the table body 50, and the spring rod 70 are assembled by such a structure. The table device 4 is configured by such an assembly structure. The base end 30b of the base frame 30 of the table device 4 is fastened to a bracket 24 fixed to the left side frame 12 of the seat cushion 2 through a through hole 20a of the left cushion shield 20 ( (See FIG. 4).

  Then, with reference to FIGS. 1-11, the effect | action of the table apparatus 4 mentioned above is demonstrated. As an explanation of this operation, a procedure for switching the table main body 50 from the usable state (see FIGS. 1 to 5) to the housed state (see FIGS. 7 to 11) will be described.

  First, the occupant performs a first operation to operate (cause) the operation unit 60a of the lever 60 from the state shown in FIG. 4 (see FIG. 6). This first work is a work against the urging force of the torsion spring. Next, the occupant performs the second operation of folding the table main body 50 along the second seat 1 while performing the first operation. Then, the spring rod 70 falls down so that the base end 72 moves through the long hole 54. Even if the moved base end 72 climbs over the lock portion 60b of the lever 60 with the tilting operation, the second operation is continued while the first operation is continued. Of course, when the moved proximal end 72 gets over the lock portion 60b of the lever 60, the first work may be canceled and only the second work may be continued.

  At this time, the spring rod 70 starts to ride on the raised portion 42c from each end 42a of the pair of cam surfaces 42 at the free end 74 side with the tilting operation. Therefore, the spring rod 70 starts to bend so that the both free ends 74 sides thereof are close to each other. Therefore, the spring rod 70 rotates with respect to the cam member 40 along the folding direction of the table body 50.

  Eventually, when both free ends 74 of the spring rod 70 reach the other ends 42b of the pair of cam surfaces 42, the bending of the free ends 74 of the spring rod 70 is eliminated. The both free ends 74 of the spring rod 70 are held. When held in this way, the spring rod 70 faces downward as already described. Therefore, the base end 72 of the spring rod 70 presses the inner surfaces of the long holes 54 of the table body 50 so that the table body 50 is folded along the second seat 1.

  Therefore, the table main body 50 can be held in the storage state (see FIGS. 7 to 11) folded along the second sheet 1. At this time, since the base end 72 of the spring rod 70 also presses the inner surfaces of the other ends 54b of the long holes 54 of the table main body 50, it is possible to prevent the table main body 50 held in the stored state from rattling. In this way, the table main body 50 can be switched from the usable state to the stored state. When this switching is completed, the first work and the second work are stopped simultaneously. Of course, as described above, if the first work is canceled and only the second work is continued, only the second work is stopped.

  On the contrary, when the table main body 50 is switched from the stored state to the usable state, the occupant may perform an operation for causing the table main body 50 to be substantially horizontal. Then, the base end 72 of the spring rod 70 gets over the lock portion 60b of the lever 60 and is returned to the locked state, and both free ends 74 side of the spring rod 70 are also held by the respective one ends 42a of the pair of cam surfaces 42. Return to state. Therefore, the table main body 50 can be returned to the usable state.

  The table device 4 of the second sheet 1 according to the embodiment of the present invention is configured as described above. According to this configuration, on the back side of the table body 50 (the surface opposite to the placement surface 50 a), the lever 60 having one end forming the operation portion 60 a and the other end forming the lock portion 60 b is interposed via the hinge pin 62. And pivotally mounted. The lever 60 is formed so that the lock portion 60b regulates the movement of the base end 72 of the spring rod 70 in the pair of long holes 54 of the table body 50 when the table device 4 is in a usable state. When the movement of the base end 72 of the spring rod 70 is restricted in this way, the holding of the spring rod 70 on both free ends 74 side with respect to the respective one ends 42a of the pair of cam surfaces 42 can also be restricted (locked). Therefore, switching (locking) the table device 4 from the usable state to the housed state can also be performed. Therefore, even if a heavy article is placed on the table main body 50 in the usable state, the table device 4 does not switch from the usable state to the stored state. As a result, even if a heavy article is placed on the table main body 50 in the usable state, it can be used.

  Further, according to this configuration, the lock portion 60b of the lever 60 is formed with the concave groove 66 into which the base end 72 of the spring rod 70 can enter when a heavy load is applied to the table body 50 in the usable state. Yes. Therefore, when a large load is applied to the table body 50 in the usable state, the base end 72 of the spring rod 70 that falls due to the large load that has been applied enters the concave groove 66 of the lever 60. Therefore, thereafter, the rotation of the lever 60 is restricted (see FIG. 12). As a result, even if the lever 60 is operated in a state where a large load is applied to the table main body 50, the lever 60 does not accept this operation, so that the table main body 50 can be prevented from being folded.

  Moreover, according to this structure, the spring rod 70 is comprised from the substantially U-shaped metal member by which the cross section was formed circularly. The concave groove 66 has a planar concave surface 66a. The concave surface 66 a is set so as to be orthogonal to the entering direction when the base end 72 of the spring rod 70 enters the concave groove 66. Therefore, it is possible to prevent the base end 72 of the spring rod 70 that has entered the concave groove 66 from slipping off the concave surface 66a and falling off the concave groove 66. Therefore, the rotation of the lever 60 is surely restricted. As a result, even if the lever 60 is operated in a state where a large load is applied to the table main body 50, the base end 72 of the spring rod 70 can be reliably prevented from being moved. Can be surely prevented. For convenience of explanation, the contact point between the concave surface 66a of the concave groove 66 and the base end 72 of the spring rod 70 is referred to as “contact point B” (see FIG. 12).

  Further, according to this configuration, on the back side of the table main body 50 (the surface opposite to the placement surface 50a), the lever 60 having the operation portion 60a at one end and the lock portion 60b at the other end is provided with the hinge pin 62. It is pivotally attached via. The center A of the base end 72 of the spring rod 70 and the lever 60 when the base end 72 of the spring rod 70 enters the concave groove 66 due to a large load acting on the table body 50 in the usable state. The contact point B between the concave surface 66a of the concave groove 66 and the base end 72 of the spring rod 70 and the center C of the hinge pin 62 of the lever 60 are set to be on the same straight line. Therefore, it is possible to reliably prevent the base end 72 of the spring rod 70 that has entered the concave groove 66 from sliding off the concave surface 66a and falling off the concave groove 66. Therefore, the rotation of the lever 60 is more reliably regulated. As a result, even if the lever 60 is operated in a state where a large load is applied to the table body 50, the base end 72 of the spring rod 70 can be more reliably prevented from moving. It can be prevented more reliably that it is rare.

  In the embodiment, the spring rod 70 is formed of a substantially U-shaped metal member having a circular cross section, and the concave groove 66 has a planar concave surface 66a. Explained the form. However, the present invention is not limited to this. For example, the cross-sectional shape of the base end 72 of the spring rod 70 is circular, and the cross-sectional shape of the concave groove 66 is also a circle corresponding to the circular shape of the base end 72. It may be in the shape. In that case, with the simple structure, the above-described effect (an effect that can more reliably prevent the table body 50 from being folded) can be obtained. Of course, the shape is not limited to a circle, and may be various shapes (for example, a triangle, a quadrangle, a hexagon, etc.).
