Description

Technical Field

[0001] The present invention relates to a table device equipped in an automobile or the like, and more particularly to a vehicle table device having a holder portion for holding an article and capable of expanding a table main body portion by a table extension portion.

Background Art

[0002] FIG. 20 shows a vehicle table device disclosed in Patent Document 1. This table device includes a table main body portion (link) 20 disposed on the armrest 103 side of the seat cushion 102 of a seat 100 which is an attachment partner, and a table extension portion (table) 10 that is received by the table main body portion 20 and is variable from a superimposed state (a) overlapping the table main body portion to an extended state (b) shifted. The table main body portion 20 is rotatably connected to a moving body 2 that is slidable in the front-rear direction provided at a right side portion of the seat 100 by a first rotation shaft 21 extending in the height direction. The table extension portion 10 has a holder portion for holding an article provided at the tip side, and is rotatably connected to the table main body portion 20 by a second rotation shaft 22.

[0003] Further, of the two opposing surfaces in the height direction between the table main body 20 and the table extension portion 10, one is an inclined concave surface 23 (not shown) that is inclined in the height direction around the second rotation shaft 22, and the other is a protruding portion 11 (not shown) that abuts against the inclined concave surface 23 from above. In this structure, when the table extension portion 10 rotates in the unfolding direction around the second rotation shaft 22 with respect to the table main body 20, the protruding portion 11 slides on the inclined concave surface 23 toward the side where it drops, and the step between the two surfaces of the table main body portion and the table extension portion is reduced. When the table extension portion 10 rotates in the storage direction around the second rotation shaft 22 with respect to the table main body 20, the protruding portion 11 slides on the inclined concave surface 23 toward the side where it rises, and the table main body portion and the table extension portion are overlapped in the height direction. That is, the step between the two plates is reduced.

[0004] [Patent Document 1] Japanese Patent Publication No. 2021-17097 [Overview of the Initiative] [Problems that the invention aims to solve]

[0005] In the structure of the above-mentioned Patent Document 1, firstly, since the holder portion for holding articles is provided in the shape of a hole on one side of the table extension portion, the depth of the hole is shallow, and containers cannot be stably held in either the overlapping configuration shown in Figure 20(a) or the extension configuration shown in Figure 20(b), where the table body portion and the table extension portion overlap. Furthermore, because the hole in the holder portion is shallow, it is difficult to provide a member to receive the containers placed inside the hole in the holder portion, and the types of articles that can be held are limited.

[0006] Therefore, the object of the present invention has been devised in view of the above background, and in particular, to improve user convenience and ease of use by making it possible to form the holder portion into a deep hole, and to enable the table area to be expanded or overlapped while stably holding an item in the holder portion. Other objects will be clarified in the following description. [Means for solving the problem]

[0007] To achieve the above objectives Claim 1 The invention is a vehicle table device comprising, as illustrated in the drawings, a table body portion (1A) attached to a mounting mating surface (4), and a table extension portion (1B) that is received by the table body portion and can be changed from an overlapping configuration that overlaps with the table body portion to an expanded configuration that moves and shifts, wherein a holder portion (3) is provided continuously at the overlapping portion of the table body portion and the table extension portion for holding and inserting articles. The table has an opening / closing mechanism (2) that allows switching between a usage state in which the table body (1A) is attached to the mounting mat (4) and a folded storage state with the pivot support (55) as the fulcrum, and the opening / closing mechanism (2) has an opening / closing mechanism (2) that is pivotally supported by a shaft member on a bracket (5) fixed to the mounting mat and on which the table body can be placed, and an engaging part (40) provided on the support plate that engages with an engaging part (15) on the table body side to connect to the table body, and disengages to separate from the support plate. It is characterized by possessing something. Furthermore, the invention of claim 2 is a configuration in which the phrase "...the opening / closing mechanism (2) is fixed to the bracket (5) that is fixed to the mounting mat" in claim 1 is changed to "...the opening / closing mechanism (2) is arranged to be finely movable on the mounting mat" as illustrated in Figures 17 to 19. Furthermore, the invention of claim 3, as illustrated in Figures 4 and 5, replaces the "...opening and closing mechanism" of claim 1, which comprises a support plate (20) pivotally supported by a shaft member on a bracket (5) fixed to the mounting mat, on which the table body can be placed, and an engaging portion (40) provided on the support plate that engages with an engaged portion (15) on the table body side to connect to the table body, and disengages to separate from the support plate, with the "...opening and closing mechanism" This configuration is a modified version comprising a structural element (2), a ball plunger (35) provided corresponding to one of the holder insertion holes (10b) provided in the table body and the table extension, and a plurality of recesses (31e) provided corresponding to the other of the holder insertion holes that engage with and disengage from a ball (35a) which constitutes the ball plunger and is biased by a spring (35b), and an angle adjustment mechanism that can elastically hold the table extension at any angle relative to the table body.

[0008] In addition, Each of the aboveIn this invention, the mounting surface can be the back of the seat back, the side of the seat cushion (Japanese Patent Publication No. 2020-66343), the side of the console box (Japanese Patent Publication No. 2000-185584), the armrest (as described in Patent Document 1), or the interior wall of the vehicle. Furthermore, the table body may be referred to as the lower table, and the table extension as the upper table.

[0009] Each of the above inventions is claimed 4 and others 7 It would be preferable if it were made more concrete like this. (a) The table extension is configured to be rotatably mounted relative to the table body (Claim 4 ).

[0010] (i) The holder portion (3) also serves as a pivot for rotating the table extension portion (1B) relative to the table body (1A) (Claim 5) .

[0011] (c) The holder portion (3) is formed of a different material from the table body portion and the table extension portion (Claim 6) .

[0012] (workman), The table body (1A) and the table extension (1B) are switchable between a tilted state where they are bent over to the back side and an upright state where they protrude to the back side, and have leg members (8, 9) of different lengths, and are configured to be supported substantially horizontally by the leg members of different lengths when the table extension is extended in a manner separate from the support plate or the mounting mat and is in the upright state (Claim). 7) . [Effects of the Invention]

[0013] Claim 1 to 3 In each invention, the holder portion is continuously provided at the overlapping location of the table body and the table extension portion, thereby ensuring a large depth dimension and stably holding items such as containers. Furthermore, while holding items such as containers in the holder portion, the table extension portion can be changed from an overlapping configuration with respect to the table body to a shifted, extended configuration, resulting in superior usability and improved convenience for the table user.

[0014] Furthermore, in each invention, for example, when the table body and table extension are not in use, the table body can be switched from the in-use state to the stored state via the opening and closing mechanism, thereby expanding the space inside the vehicle and improving usability.

[0015] Furthermore, in the invention of claim 1, the opening and closing mechanism has a bracket to which it is fixed to a mounting surface, and a support plate on which the table body can be placed is rotatably attached to the bracket. As shown in the example, the engaging portion of the support plate can be disengaged from the engaged portion of the table body, allowing the table body to be detached from the support plate together with the table extension. Since the detached table body and table extension are separated from the opening and closing mechanism, they can be used as a table for camping and other purposes, making them highly versatile.

[0016] On the other hand, the invention of claim 2 has a bracket that is positioned to be slightly movable on the mounting mat, and as in the modified example, when the engaging part of the bracket is released from the engaged part on the mounting mat side and the table body is removed from the mounting mat together with the table extension part, the opening and closing mechanism does not remain on the mounting mat, resulting in a better appearance and a larger interior space.

[0017] In the invention of claim 3, the table extension can be held at various angles via the angle adjustment part, always in the most preferred position, allowing for stable use and improving convenience.

[0018] In the invention of claim 4, when the table extension is extended, the rotary type is structurally simpler and easier to use than the sliding type.

[0019] In the invention of claim 5, since the holder portion also serves as the pivot of the table extension portion, the table extension portion can be changed from an overlapping configuration to an extended configuration and from an extended configuration to an overlapping configuration while an article is placed in the holder portion, thus improving the usability of the table. Furthermore, since the holder portion also serves as the pivot, it becomes easy to set the hole dimensions to be deeper and to add receiving members to hold the article.

[0020] In the invention of claim 6, since the holder portion is formed from a different material than the table body portion and the table extension portion, that is, from a dedicated material, simplicity can be maintained, and the bottom plate, receiving plate, and angle adjustment portion of the holder portion can be easily provided.

[0021] Claims 7 In the invention, the table main body part is separated from the support plate or the mating part together with the table extension part, and the table extension part is extended and supported substantially horizontally by leg members having different lengths in the standing state, so that it can be used as a table with legs outside the vehicle and has high versatility.

Brief Description of the Drawings

[0023] The vehicle table device of the present invention will be described below with reference to the drawings. This description will first clarify the ingenious structure and main operation of the table device in its form, and then discuss a modified version in which the table device is detachable from its mounting surface.

[0024] (Device Structure) This vehicle table device, as shown in the drawing, is of the type that comprises a table body 1A attached to the seat back 4 of the seat to which it is mounted, and a table extension 1B that is received by the table body 1A and can be changed from an overlapping state where it overlaps with the table body to an extended state where it moves and shifts. The main innovations are the configuration of the holder section 3 that holds containers C and electronic devices, which is provided continuously on the table body 1A and the table extension 1B, the configuration that allows the table body 1A and the table extension 1B to be used as a table with legs, and the opening and closing mechanism section 2 that switches the table body 1A together with the table extension 1B between a usage state where it is approximately perpendicular to the seat back 4 and a folded storage state. These innovations will be explained in order below.

[0025] In this specification, the term "overlapping state" refers to a stacked state in which the table body 1A and the table extension 1B almost completely overlap their opposing surfaces. The term "extension state" refers to a state in which the table body 1A and the table extension 1B are shifted in relative position or angle from the overlapping state.

[0026] (Construction of each table and holder section) The table body section 1A and the table extension section 1B are resin molded bodies and are stacked vertically, forming rectangular plates with substantially the same contour. For this reason, the same parts and locations are given the same reference numerals in the drawings. The table body section 1A and the table extension section 1B are separated by a surface 10, a back surface 11, and a surrounding wall 12, as shown in Figures 2, 4 and 5, and 12 and 13, forming a shallow container shape with the back side separated by the surrounding wall 12. The surrounding wall 12 of the table body section is provided with notches 12a for operating knobs on both the left and right sides, and the surrounding wall 12 of the table extension section is provided with a single notch 12a. In addition, the inside of the surrounding wall 12 of the table body section, i.e., the back surface 11, is provided with a pair of locking projections 15, 15 which are engaging parts that protrude approximately in the center and maintain a predetermined distance apart, and a pair of protruding pieces 16c which protrude away from the locking projections 15. Of these, each locking projection 15 faces the other with a slight offset from one another and has a recess 15a formed on the opposing surface. The protruding piece 16c is for preventing rattling.

[0027] The underside 11 of the table body 1A has four regulating walls 16 for restricting the position of the leg members, protruding from the left, right, front, and rear, as shown in Figure 12; bearing protrusions 14 and 17 provided inside each regulating wall 16, spaced apart by the width of the U-shaped side plates of the leg member 8; contact parts 13 that receive each side 8b of the leg member 8 when it is upright; and positioning pieces 16a, 16a and 16b, 16b that restrict the support plate 20 (described later) from the left and right. On the other hand, the underside 11 of the table extension 1B has two regulating walls 16 for restricting the position of the leg members, protruding from the left, front, and rear, as shown in Figure 13; bearing protrusions 14 and 17 provided inside each regulating wall 16, spaced apart by the width of the U-shaped side plates of the leg member 9; and contact parts 13 that receive each side 9b of the leg member 9 when it is upright.

[0028] The surface 10 of the table extension portion 1B is provided with elongated grooves 10a in the left-right direction for inserting and holding sheet-like members such as tablets. These elongated grooves 10a are not provided on the surface 10 of the table body portion 1A, but they may also be provided on the table body portion 1A.

[0029] The table body 1A and the table extension 1B have holes 10b through which the cup holder 30 is inserted on different sides; in this example, the table body 1A and the table extension 1B are arranged in an overlapping configuration with the left side facing each other. The hole 10b of the table body 1A has a step 10c that is slightly larger in diameter than the hole 10b of the table extension 1B, as shown in Figure 5, and four mounting holes 10d provided on the inner circumference of the step 10c. A cup holder 30 is fitted into each hole 10b. The cup holder 30 has a large-diameter rim 30a formed on its upper outer circumference, a receiving plate 30b provided on the inner side of its lower end to receive containers, and a fitting groove 30c provided around the outer circumference of its lower end. Then, as shown in Figure 4, the cup holder 30 is fitted into the hole 10b of the table extension 1B, the hole 31c of the bearing holder 31 mounted on the table extension 1B, and the hole 10b of the table body 1A, and is then fixed to the table body 1A by the left and right retaining plates 37a, 37b and the fixing plate 38 mounted on the table body 1A.

[0030] More specifically, the bearing holder 31 has a hole 31a arranged coaxially with the hole 10b as shown in Figure 5, an upper step 31b for positioning the upper bearing 32, a lower step 31c for positioning the lower bearing 33, multiple mounting holes 31d penetrating in the vertical direction, and multiple recesses 31e provided at equal intervals around the lower cylindrical portion. The bearing holder 31 is positioned on the back side of the table extension 1B as shown in Figures 4 and 5, and is fixed by tightening fasteners B1 such as screws through the mounting holes 31d to the corresponding parts of the table extension. At that time, the upper bearing 32 is incorporated between the step 31b and the periphery of the cup holder 30.

[0031] Next, the table extension 1B is connected to the table body 1A in an angle-adjustable manner via the cup holder 30 and angle adjustment mechanisms (31e, 35). In this operation, first, ball plungers 35 are assembled into each of the mounting holes 10d of the table body. As shown in Figure 4(c), the ball plunger 35 has a ball 35a that is biased outward from the cylindrical member by a spring 35b inserted inside the cylindrical member. In this connection structure, the left and right holder retaining plates 37a and 37b are fitted into the lower fitting groove 30c of the cup holder 30, and then the fixing plate 38 is placed on top of each retaining plate 37a and 37b. From this state, a plurality of fasteners B2 are tightened to the table body 1A through mounting holes provided in the fixing plate 38 and mounting holes provided in the retaining plates 37a and 37b.

[0032] As described above, when the table body 1A and the table extension 1B are connected so as to be rotatable relative to each other with the cup holder 30 as a pivot, the ball 35a of the ball plunger elastically engages with the recess 31e of the bearing holder, that is, elastically engages to prevent the table extension 1B from rotating unintentionally. Furthermore, for example, when the table extension 1B is rotated with a predetermined force, the recess 31e of the linked bearing holder elastically disengages from the ball 35a, allowing rotation. In other words, the recess 31e and the ball plunger 35 constitute an angle adjustment mechanism that allows the table extension 1B to be elastically held at any angle relative to the table body 1A. In this example, the table extension 1B may rotate clockwise or counterclockwise, and in either case, engagement and disengagement are repeated every 30 degrees of rotation of the table extension 1B.

[0033] (Table configuration with legs) Next, the leg members 8 provided on both sides of the underside of the table body and the leg member 9 provided on one side of the underside of the table extension will be described with reference to Figures 12 to 15. Each of the restricting walls 16 on the underside 11 described above restricts the front-to-back position of the leg member 8 by positioning each side portion 8b of the leg member inward. Each leg member 8 is U-shaped, with the corresponding side portion 8b positioned between the restricting wall 16 and the protruding wall 14, and between the restricting wall 16 and the protruding wall 17, and is pivotally supported by a shaft member 18 so as to be rotatable. It also has an operating knob 19 that can hold the leg member 8 in an upright position or release the hold in the upright position against the biasing force of the spring 3 to switch it to an upright position.

[0034] As shown in Figures 12(b) and (c), the operating knob 19 integrally comprises a gripping portion 19a, an intermediate portion 19b, a stopper contact portion 19c protruding from one side of the intermediate portion 19b, and a spring locking portion 19d at the rear of the intermediate portion 19b. The operating knob 19 has a gripping portion 19a positioned to be operated by a finger in a notch 12a provided in the surrounding wall 12, and the intermediate portion 19b extends away from the notch 12a through the space below the shaft member 18. The operating knob 19 is biased away from the surrounding wall 12 by a coil-shaped spring S3 whose ends are hooked between the locking portion 19d and a locking portion 17a provided at the rear of the protruding portion 17. In this biased state, the contact portion 19c fits into the gap between the lower end of one of the side portions 8b of the leg member 8, i.e., the back surface 11 and the corresponding side portion 8b.

[0035] Therefore, in the overturned state shown in Figure 12, the leg member 8 does not rattle unintentionally even when vibrations are applied due to the presence of the contact portion 19c. Furthermore, when switching the leg member 8 to the upright state shown in Figure 14, the grip portion 19a is pulled with the fingers against the biasing force of the spring S3 to separate the contact portion 19c from the corresponding side portion 8b of the leg member, and then it is rotated to switch to the upright state. When the leg member 8 is switched to the upright state, each side portion 8b contacts the contact portion 13 and is held at an angle greater than 90 degrees. As a result, the table extension portion 1B is stacked on top of the table body portion 1A in a superimposed manner, resulting in a stable and convenient table with legs.

[0036] In this table device, the table extension section 1B may be used with the leg members 8 of the table body section 1A supported as shown in Figure 14. However, if the height needs to be increased further, the auxiliary leg 8A is reversed from the leg member 8 using the shaft member 18a as a pivot point, as shown in Figure 15. That is, the auxiliary leg 8A has a roughly U-shape, and both ends of its intermediate section 8a are pivotally supported by the shaft member 18a to both ends of the intermediate section 8a on the leg member side, allowing it to rotate by approximately 90 degrees. Furthermore, the auxiliary leg 8A is formed in a flat plate shape with its intermediate section 8a overlapping the intermediate section 8a on the leg member side, and both side sections 8b are formed in an L-shape in cross-section, overlapping the corresponding side sections 8b of the leg member.

[0037] Furthermore, the auxiliary leg 8A extends the protruding dimension of the leg member 8 when it is upright, with its intermediate portion 8a positioned on the end face of the intermediate portion 8a on the leg member side, and each side portion 8b positioned on the extension line of the side portion 8a of the leg member. In addition, the auxiliary leg 8A is superimposed on the leg member 8 when it is in a tipped-over state. That is, the intermediate portion 8a of the auxiliary leg is superimposed on the inner surface of the intermediate portion 8a of the leg member, and each side portion 8b of the auxiliary leg is superimposed on the inner surface of the corresponding side portion 8b of the leg member. In this case, since each side portion 8b of the auxiliary leg has an L-shaped cross-section, when the leg member 8 is tipped over, one side of the L-shape is sandwiched between the underside 11 of the table body and the corresponding side portion 8b of the leg member. Therefore, the auxiliary leg 8A is less likely to rattle even when vibrations are applied.

[0038] On the other hand, the leg member 9 of the table extension 1B is used together with the leg member 8 in the extended configuration, and the front-to-back position of the leg member 9 is restricted by positioning each side portion 9b of the leg member inward relative to each restricting wall 16 of the back surface 11. That is, the leg member 9 has a U-shape, and the corresponding side portion 9b is positioned between the restricting wall 16 and the protruding wall 14, and between the restricting wall 16 and the protruding wall 17, and the shaft member 18 It is pivotally supported so as to be rotatable. It also has an operating knob 19 that can hold the leg member 9 in a tilted position, or release the tilted position against the biasing force of the spring 3 and switch to an upright position.

[0039] The operating knob 19 is identical in structure and function to the operating knob 19 of the leg member 8, so its description is omitted. The leg member 9 is longer than the leg member 8, and in the overturned state shown in Figure 13, the presence of the contact portion 19c prevents it from rattling unintentionally even when vibrations are applied. To switch the leg member 9 to the upright state shown in Figure 16, the gripping portion 19a is pulled with the fingers against the biasing force of the spring S3 to separate the contact portion 19c from the corresponding side portion 9b of the leg member, and then it is rotated to switch to the upright state. When the leg member 9 is switched to the upright state, each side portion 9b contacts the contact portion 13 and is held at an angle greater than 90 degrees.

[0040] As a result, the table extension 1B functions as a table with legs together with the table body 1A in its extended state. In other words, in the state of use of the table with legs shown in Figure 16, the table extension 1B is rotated 180 degrees relative to the table body 1A, and it can be used as a tall table with legs using the leg members 8 and 9 extended by the auxiliary leg 8A. In this case, by switching the other leg member 8 of the table body 1A from the tilted state to the upright state, it can be supported more stably by three legs.

[0041] (Opening / Closing Mechanism) Next, the detailed configuration of the opening / closing mechanism 2 will be shown in Figures 1 to 3 and Figures 7 to 11. The opening / closing mechanism 2 includes a bracket 5 fixed to the back of the seat back 4b, a support plate 20 rotatably supported by the bracket 5 on which the table body 1A is detachably mounted, a pair of engaging plates 40 which are locking parts that are slidably provided on the support plate 20 in the left-right direction and engage with and disengage from locking projections 15, 15, a spring S1 which biases each engaging plate 40 in the protruding direction, an upper lever 41 which switches each engaging plate 40 from the protruding state in the engaging direction to the retracted direction by operation against the biasing force of the spring S1, a pair of cams 6 fixed to the bracket 5, and a shaft 7 which slides along a guide groove 27 provided on the support plate 20 while being rotatably supported by each cam 6, and a shaft portion on the support plate 20 43The device includes a lower lever 46 that is pivotally supported so as to be rotatable and restricts or allows sliding of the shaft 7 within the guide groove 27, and a spring S2 that biases the lever 46 in a counterclockwise direction. The lower part of Figure 7 also shows the lever 46, shaft portion 43, and spring S2 before they are assembled to the support plate 20.

[0042] Bracket 5 is a metal plate and consists of horizontal plate sections 50 extending to the left and right, and a pair of vertical plate sections 51, 51 that are integrated with the horizontal plate sections 50 and extend downward while maintaining a gap. Holders 28 are fixed to the horizontal plate sections 50 on the left and right sides, and the table body section 1A or support plate 20 rotates around the shaft member 55 as a pivot point relative to each holder 28 to switch between the usage state shown in Figures 1 and 2 and the storage state shown in Figure 3. Each holder 28 is fixed to bracket 5 with bolts, but it is also possible to fix them with a joint structure or to form them integrally with bracket 5.

[0043] As shown in Figure 10, the support plate 20 is roughly T-shaped and consists of horizontal plate sections 21 extending to the left and right, and vertical plate sections 22 extending in a direction intersecting the horizontal plate sections from the left and right middle sections, with its upper surface covered by a cover 29. The horizontal plate sections 21 have holes 21a that penetrate vertically on both sides, and holders 28 are placed in each hole 21a. Each holder 28 has a coaxial shaft hole 28a provided in the opposing side walls, and is incorporated so as to be rotatable relative to each other by a shaft member 55 that is inserted in a skewer-like manner into each shaft hole 28a from the hole on the end face of the horizontal plate section 21 while it is placed in the hole 21a. The U-shaped middle section of each holder 28 is fixed to the bracket 5 with bolts or the like. In this state, the support plate 20 becomes rotatable with the shaft member 55 as a pivot point, and can be switched between the usage state shown in Figure 9(a) and the storage state shown in Figure 9(b).

[0044] The upper surface of the vertical plate portion 22 has, as shown in Figure 11, two side positioning portions 23 provided slightly in front of the tip, groove portions 24 provided on the left and right sides of the positioning portion 23 for positioning coil-shaped springs S1, and a shaft portion 25 protruding from the center of the positioning portion 23. An engaging plate 40 is positioned in each positioning portion 23 together with the spring S1. The engaging plate 40 has a substantially inverted L-shaped engaging portion 40a that engages with and disengages from the recess 15a of the locking projection, an extension portion 40b provided on the rear side of the engaging portion 40a, a shaft portion 40d provided on the upper surface of the extension portion 40b, and a shaft portion 40c protruding rearward from the rear end surface of the extension portion 40b. Each engaging plate 40 is assembled to the left and right positioning portions 23 with the spring S1 positioned around the shaft portion 40c, so that the spring S1 fits into the corresponding groove portion 24. As a result, the left and right engaging plates 40 are extended to their maximum extent by the biasing force of the spring S1, as shown in Figure 10(a). From this state, the lever 41 is incorporated into the support plate 20.

[0045] The lever 41 has a shape in which the front side of the straight plate portion is bent downward, forming a gripping portion 41a at the bent part and three axial holes 41c arranged at equal intervals in the straight plate portion 41b. When the lever 41 is assembled to the support plate 20 with the central axial hole 41c fitted onto the shaft portion 25 and the front and rear axial holes 41c fitted onto the shaft portions 40d of the left and right engaging plates, the gripping portion 41a at the tip is positioned along the tip surface of the vertical plate portion 22. Finally, the cover 29 is attached to the support plate 20 by engaging multiple screws B3 from the holes 29a on the cover side into the holes 20a on the support plate side. Normally, as shown in Figure 10(a), the left and right engaging plates 40 are protruding due to the biasing force of the spring S1 and are in the engaged position, so the lever 41 is tilted in a counterclockwise direction with the shaft portion 25 as the pivot point. Figure 10(b) shows that when the gripping part 45a is moved in the direction of the arrow against the biasing force from that state, each engaging plate 40 retracts in the direction of retraction, moving closer to each other, and is switched to the disengaged position.

[0046] Furthermore, the lower surface of the vertical plate portion 22 has two groove-forming projections 26 that extend in a straight line from the front to the rear, as shown in Figure 8, and guide grooves 27 provided on each projection 26. The projections 26 are provided at a predetermined distance from each other. A pair of bearing portions are provided on the tip side of each projection 26. 26aA part is provided protruding from the outer surface. The lower lever 46 has an operating part 46a, a thick plate part 46b that protrudes rearward from the operating part 46a and forms an axial hole 46d that penetrates from left to right, and a locking plate part 46c that protrudes rearward from the end face of the thick plate part 46b. The thick plate part 46b is not shown in the figure, but the middle part is cut out in a concave shape.

[0047] The lever 46 described above has a thick plate portion 46b which is the bearing portion. 26a It is positioned between them, and the shaft member 43 is one of the bearing parts 26a After being inserted through the shaft hole (not shown) of the plate thickness portion 46b, the other bearing portion 26a The shaft is inserted into the shaft hole (not shown) and pivotally supported in a state where it is prevented from coming out by attaching a retaining ring E to the protruding shaft portion. In addition, a coil-shaped spring S2 is arranged on the shaft portion of the shaft member 43 that passes through the concave shape. One end of the spring S2 is locked to the thick plate portion 46b, and the other end is locked to the corresponding upper surface portion of the lever 46 while exerting a biasing force. The lever 46 is biased counterclockwise by the biasing force of the spring S2 as shown in Figure 8, and the locking plate portion 46c is inserted into the gap between the protrusions 26. In this state, the intermediate portion 7a of the shaft 7, which will be described later, is restrained by the locking plate portion 46c to the rear end side of the guide groove 27, as shown in Figures 7 and 8.

[0048] Each cam 6 is made of a resin molded body and is positioned opposite the vertical plate portions 51, 51 of the bracket. It integrally forms a fixing base portion 6a, a vertical wall portion 6b erected on the base portion 6a, and a shaft hole 6c provided in the inner wall portion 6b, as well as a cam portion for pressure contact centered on the shaft hole 6c. The cam portion is not shown in the figure, but it is the point where the corresponding portion of the shaft 7 makes pressure contact. The base portion 6a is flat and is fixed to the bracket 5 with multiple screws or the like. The vertical wall portion 6b is made thick and has a predetermined rigidity provided by reinforcing ribs on the back side. The shaft hole 6c is thickly provided from the inner surface of the vertical wall portion 6b, into which the end 7c of the shaft 7 is inserted. The cam portion is located on the lower inner surface of the vertical wall portion 6b and is formed on an inclined surface.

[0049] The shaft 7 is made of a round metal wire material and is bent into a roughly U-shape to form an intermediate piece 7a and two side pieces 7b. The total length of the shaft 7 is such that, in the configuration shown in Figure 1 where the table device is in use, the U-shaped intermediate piece 7a moves to the rear end of the guide groove 27. The two side pieces 7b of the U-shape are arranged so that the distance between them gradually widens as they approach the terminals 7c. Both terminals 7c are pivotal parts bent outwards. This shape of the two side pieces 7b is such that elastic force is exerted when the distance between them narrows. For details on the configuration and operation of the cam 6 and shaft 7, please refer to the cam section 45 and shaft 3 described in Japanese Patent Publication No. 4451549.

[0050] (Main Operation) The above-mentioned vehicle table device has the following advantages compared to conventional structures. (1) In this configuration, as shown in Figures 6(a) and (b), the table extension 1B rotates, for example, 180 degrees relative to the table body 1A, using the cup holder 30 as a pivot, and engaging and disengaging repeatedly at predetermined angles by the angle adjustment mechanism of the ball plunger 35 and recess 31e, so that it is positioned in a straight line as shown in Figure 6(c). With this structure, a sense of control is obtained when the table extension 1B rotates due to the angle adjustment mechanism, and after rotation, the table extension 1B and the table body 6A can be used in a stable state without being unintentionally moved by vibration or the like. Furthermore, when the table extension 1B is positioned in a straight line with the table body 6A, the table receiving surface is considerably enlarged, as can be inferred from Figure 2, making it easier for occupants to use. Also, when it is mounted on the seat back 4a of the driver's seat, it becomes easier for occupants sitting in the rear seats and occupants sitting in the auxiliary seats to share the table surface.

[0051] (2) Moreover, in this configuration, when the container C is held in the holder part 3 in the combined configuration of the table body part 1A and the table extension part 1B in Figure 1, the table extension part 1B can be rotated to switch to an extended configuration of a predetermined angle while maintaining the state in which the container C is held, or to switch back from the extended configuration to the combined configuration. In this way, this structure is convenient because it allows switching between the combined configuration and the extended configuration without worrying about the container C. Of course, the same applies when a tablet or booklet is held in the long groove 10a.

[0052] (3) In this table device, the bracket 5 constituting the opening / closing mechanism 2 is fixed to the back of the seat back 4b or the side of the seat cushion, and the table body 1A and the table extension 1B are connected and supported to the opening / closing mechanism 2 by engaging the engaging plate 40 with the locking projection 15 which is the engaged part. The table body 1A and the table extension 1B can be separated from the opening / closing mechanism 2 by disengaging them. Therefore, with this structure, the interior space can be used more widely and comfortably by separating the table body 1A and the table extension 1B from the opening / closing mechanism 2, and the separated table body 1A and the table extension 1B can be carried outside the vehicle and used as a table for camping, etc., making it highly versatile.

[0053] (4) In the operation of connecting the table body 1A to the opening / closing mechanism 2, as can be inferred from Figure 8, the table body 1A and the table extension 1B are held and pushed down so that each locking projection 15 contacts the corresponding engaging plate 40 of the opening / closing mechanism 2. Then, each engaging plate 40 moves from a protruding state to a retracted state against the biasing force of the spring S1 and enters the corresponding recess 15a, and at the same time moves in the protruding direction due to the biasing force of the spring S1 and engages with the corresponding recess 15a. On the other hand, in the operation of separating the table body 1A, the gripping part 45a is pushed with the fingers in the direction of the arrow in Figure 10(b) and the lever 45 is rotated, and each engaging plate 40 is switched from a protruding state to a retracted state and disengaged from the corresponding recess 15a. All that remains is to lift the table body 1A and the table extension 1B. Thus, in this structure, both the operation of engaging and connecting the table body 1A to the opening / closing mechanism 2 and the operation of disengaging and separating it can be done with a single touch. Therefore, this table device offers excellent operability and ease of use.

[0054] (5) The opening / closing mechanism 2 has a bracket 5 fixed to the seat side, and a support plate 20 on which the table body 1A and the table extension 1B can be placed is rotatably attached to the bracket 5, making it easy to adopt an engagement structure for attaching and detaching the table body 1A to the support plate 20. Furthermore, the table body 1A and the table extension 1B that have been removed from the support plate 20 can be configured with leg members as shown in the example, improving usability outside the vehicle, and moreover, as shown in Figure 9, it is easy to switch the support plate 20 of the opening / closing mechanism 2 between the open state and the folded state.

[0055] (6) The engaging plate 40, which is the locking part, is switched from a protruding state in which it engages with the locking projection 15, which is the engaged part, to a retracted state in which the lever 45 is pushed against the biasing force of the spring S1 to release the engagement. For this reason, in this opening and closing mechanism 2, for example, the engaging plate 40 on the support plate side can be easily engaged with the locking projection 15 of the table body 1A simply by pressing it against the biasing force. Furthermore, in the engaged state of the engaging plate 40 and the locking projection 15, the engaging plate 40 is always biased in the protruding direction by the biasing force, so the risk of rattling even when running vibrations are applied, and the risk of unintentional release, can be reliably eliminated.

[0056] (7) In this structure, when the table body 1A and the table extension 1B are to be used, the table body 1A and the table extension 1B are rotated using the shaft member 55 as a pivot point to lift them from the stored state shown in Figure 3. As a result, the table body 1A and the table extension 1B are rotated upward as the shaft 7 moves along the guide groove 27 with the intermediate piece 7a at its tip, and finally the locking plate 46c of the lever 46 is pushed out of the guide groove 27 against the biasing force of the spring S2 and moves to the rear end of the guide groove 27. Simultaneously with this movement, the lever 46 is rotated by the biasing force of the spring S2, and the locking plate 46c enters the guide groove 27, restricting the movement of the intermediate piece 7a and keeping the table body 1A and the table extension 1B in the usable state. Therefore, in this structure, even if a large external force is applied to the table body 1A or the table extension 1B, the stability of the usable state is maintained.

[0057] (8) On the other hand, to switch the table body 1A and the table extension 1B to the stored state, the operating part 46a of the lower lever 46 is pushed upward while the table body 1A and the table extension 1B are pushed downward. When the lever 46 is pushed, it rotates in a seesaw manner around the shaft member 43 as a pivot point, and the rear locking plate 46c is displaced slightly downward, releasing the holding state (i.e., relative movement between the table body 1A and the shaft 7 is permitted). As a result, the table body 1A and the table extension 1B can rotate to the stored state along the rotation trajectory of the shaft 7, with the shaft 7 acting as a guide in the guide groove 27. In the stored state, the ends of both pieces 7b of the table body 1A and the table extension 1B are pressed against the cam portion of the corresponding cam 6, so that they do not rattle or rotate inadvertently upward even when vibration is applied.

[0058] (9) The table body 1A, separated from the opening / closing mechanism 2, together with the table extension 1B which is superimposed as shown in Figure 14, has leg members 8 that can be switched between a tilted state and an upright state, and an operating knob 19 for holding the leg members 8 in the tilted state or releasing the hold of the tilted state. When the operating knob 19 is pulled outward against the biasing force of the spring S3, the contact portion 19c disengages from between the back surface 11 and the side portion 8b of the leg member, thereby allowing the leg member 8 to rotate. For this reason, in this structure, for example, the table body 1A and the table extension 1B can be carried outside the vehicle in a separated state, detached from the opening / closing mechanism 2, and with the operating knob 19 pulled against the biasing force of the spring 3, each leg member 8 can be rotated outward around the shaft member 18 as a pivot point, and it can be used as a table with the leg members 8 attached.

[0059] (10) In this case, the leg member 8 is restricted by the contact portion 19c to prevent it from unintentionally standing up when it is tipped over via the operating knob 19, so rattling can be suppressed even when running vibrations are applied. Moreover, in this structure, as shown in Figure 15, the leg member 8 has an auxiliary leg 8A that can be switched between a shortened configuration in which it is arranged along the outer circumference and an extended configuration in which the protruding dimension is extended, and by simply rotating the auxiliary leg 8A around the shaft member 18a as a pivot point, the table height can be increased by switching to the extended configuration, thereby improving the usability of the table.

[0060] (11) In addition, in this structure, as illustrated in Figure 16, the table extension part 1B can be rotated by a predetermined angle relative to the table body part 1A to be extended, allowing it to be used as a long table with legs. That is, in the table with legs shown in the figure, the table extension part 1B is positioned in a straight line with the table body part 1A, and is supported horizontally at a predetermined height by the leg members 8 and auxiliary legs 8A of the table body part 1A and the leg members 9 of the table extension part 1B. In this case, the stability of the table when in use can be further improved by switching the leg members 8, which are in a tipped state on the table body part 1A shown in the figure, to an upright state, and by extending the auxiliary legs 8A to create a three-legged support.

[0061] (Modified Version) This vehicle table device differs from the above-described form in that the opening / closing mechanism 2 is detachable from the seat back 4 or seat cushion of the seat to which it is attached, as shown in Figures 17 to 19. In this description, the same reference numerals are used for the same components and parts as in the above-described form, and new reference numerals are added for different components and parts to minimize redundant descriptions.

[0062] In Figures 17 to 19, the vehicle table device is composed of a table body 1A and a table extension 1B, an opening / closing mechanism 2, and a holder 3, similar to the above embodiment. The relationship between the table body 1 and the opening / closing mechanism 2 is the same as in the above embodiment, meaning that the table body 1A and the table extension 1B can be attached to and detached from the opening / closing mechanism 2 by the engagement and disengagement of a locking projection 15, which is the engaged part, and an engaging plate 40, which is the engaging part. However, in modified device structures, the table body 1A and the table extension 1B may be in a configuration that is not detachable from the opening / closing mechanism 2 (for example, the configuration disclosed in Japanese Patent Publication No. 4451549).

[0063] The novel configuration features a pair of hooks 49, which serve as the engaged portion, protruding from the back surface 4b of the seat back of the seat to which it is attached, and a pair of engaging holes 53 and 54, which engage with and disengage from each hook 49, provided on the bracket 5 of the opening / closing mechanism 2.

[0064] Here, the hook 49 is roughly L-shaped, with the horizontal piece 49a fixed to the corresponding part of the frame 40, which is the structural member of the seat back 4, or to a plate 41 joined to the frame 40, and the vertical piece 49b positioned upward along the back surface 4b. The tip of the vertical piece 49b is a claw portion 49c that protrudes slightly in the same direction as the horizontal piece 49a. The engagement hole 53 is a rectangular hole of approximately the size into which the hook 49 can be inserted, as shown in Figure 17(a). The engagement hole 54 is smaller in vertical dimension than the engagement hole 53, and is shaped to engage with the claw portion 49c when inserted.

[0065] Furthermore, the seat back 4 has a frame 45 formed in a roughly frame shape as shown in the schematic diagram of Figure 17(b), a urethane foam 47 held by the frame 45, and a surface material 48 covering the urethane foam 47. The upper part of the frame 45 is fitted with a retaining part for inserting a headrest stay (not shown) and a plate material 46. The ends of the horizontal piece 49a are joined to the plate material 46, but the ends of the claw portion 49c are not joined. Therefore, although the claw portion 49c is in contact with the urethane foam 47, when the area near the claw portion of the urethane foam 42 is pressed, a gap is formed between it and the tip of the claw portion 49c.

[0066] (Main Operation) Next, the operation of attaching and detaching the opening / closing mechanism 2 to the seat back 4b will be described. Note that in this operation, the opening / closing mechanism 2 may be connected to the table body 1A, or the table body 1A may be separated. Specifically, Figure 18(a) shows the bracket 5 on the opening / closing mechanism side approaching the seat back 4b by inserting the hooks 49 corresponding to the left and right engagement holes 53 of the bracket 5. Figure 18(b) shows the state in which, with the hooks 49 corresponding to the left and right engagement holes 53 inserted, the bracket 5 on the opening / closing mechanism side is moved downward while being pressed, so that the horizontal piece 49a of each hook contacts the upper end surface of the engagement hole 53 and the claw portion 49c enters the upper engagement hole 54. Figure 19(a) shows the state in which the pressing force of the bracket 5 is released and the claw portion 49c engages with the engagement hole 54 and is fixed in place by the reaction force of the urethane foam 47. With this simple operation, the bracket 5 on the opening / closing mechanism side is fixed to the back of the seat back 4b by the engagement of the engagement holes 53, 54 and the hooks 49.

[0067] Furthermore, to release the engagement and separate the bracket 5 on the opening / closing mechanism side from the seat back 4, for example, if the bracket 5 is pushed toward the seat back 4 from the state shown in Figure 19(a), the claw portion 49c disengages from the engagement hole 54 and the engagement is released. From that state, if the bracket 5 on the opening / closing mechanism side is moved upward, the horizontal piece portion 49a contacts the lower end surface of the engagement hole 53, as shown in Figure 18(a), and the claw portion 49c enters the engagement hole 53. From this state, if the bracket 5 on the opening / closing mechanism side is separated from the back surface 4b of the seat back, it can be separated and carried independently.

[0068] Therefore, in this modified example, by disengaging the engagement holes 53 and 54 of the bracket 5 from the hooks 49 on the seat back side and removing the bracket 5 (opening / closing mechanism 2) from the seat back 4, the bracket 5 (opening / closing mechanism 2) does not remain on the seat back 4 side, resulting in a better appearance and increased interior space. Furthermore, in this structure, engagement or disengagement can be easily performed by moving the bracket while the hooks 49 are inserted into the engagement holes 53 and 54 of the bracket 5. This operation is easy to handle because the bracket 5 is integrated with the opening / closing mechanism 2, or integrated with the opening / closing mechanism 2 and the table body 1A.

[0069] While the present invention can be embodied in the forms and modifications described above, it is modifiable except for the technical elements described in claim 1. For example, the configuration for receiving the bottom surface of containers in the cup holder may be such that it is received by a dedicated fixed or tilting member. Also, the long groove in the table extension portion may be omitted, or conversely, a long groove may be provided in the table body portion. [Explanation of Symbols]
