Abstract
Description
[Technical Field]
[0001] The present invention relates to a mounted article rotating mechanism for rotating a placed article, and more particularly to a mounted article rotating mechanism suitable for a rotating seat (mounted article) for a vehicle, and an automobile equipped with the same as an automobile seat rotating mechanism. [Background technology]
[0002] BACKGROUND ART Conventionally, for example, a rotation mechanism such as that shown in Japanese Patent No. 3575354 (Patent Document 1) has been known as a rotation mechanism used in a rotation seat for a vehicle. The rotation mechanism described in the publication is a swivel seat for a vehicle that can rotate between a seating position facing the front of the vehicle and a sideways position facing the side of the vehicle for getting in and out, and includes a rotation support base for supporting a seat body so that it can rotate horizontally between the seating position and the sideways position, and a width direction support base for supporting the seat body so that it can move in the vehicle width direction, and the width direction support base includes a fixed frame body having a pair of left and right fixed rails fixed parallel to each other to the vehicle floor or the rotation support base, an intermediate slide frame body having a pair of left and right first movable rails supported movably along the insides of the fixed rails and a connecting plate connecting the first movable rails, and a top slide frame body having a pair of left and right second movable rails supported movably along the insides of the first movable rails and a connecting plate connecting the second movable rails, and the seat body is supported by the top slide frame body, so that the seat body can be moved in two directions. The top slide frame is configured to be slidable in the vehicle width direction in stages, and a first drive unit is disposed between the fixed rails and connected to the connecting plate of the intermediate slide frame to move the intermediate slide frame relative to the fixed frame, and a second drive unit is disposed between the first movable rails and connected to the connecting plate of the top slide frame to move the top slide frame relative to the intermediate slide frame.
[0003] However, since the rotation mechanism is designed to move a physically disabled person or the like outside the vehicle while remaining seated, it is not suitable as a rotation mechanism for rotating the second row seats to face the third row seats in a vehicle with, for example, three or four rows of seats.
[0004] Furthermore, in the case of a vehicle with three or four rows of seats, if a completed vehicle is retrofitted with a swivel-facing seat, it is necessary to provide a rotation allowance so that the seat does not come into contact with the inner wall when it rotates, and the structure must be simple.
[0005] Therefore, the present applicant proposed Japanese Patent No. 6763502 (Patent Document 2) to solve the above-mentioned problems. The rotation mechanism described in the publication includes a support frame formed of a rectangular frame, a rotary slide body having a square (including square and rectangular) frame body supported on the frame of the support frame and movable in the longitudinal direction of the frame body, a rotary plate including an upper plate and a lower plate fixed to the rotary slide body, and a rotary plate interposed between the upper plate and the lower plate, and a slide member protruding downward from a lower part of the lower plate at a position corresponding to the support member, the upper plate of the rotary slide body is fitted into the interior of the support frame in the height direction to prevent rotation, and as the rotary slide body slides in the longitudinal direction of the support frame, the slide member rides on the support member and moves upward, and the upper plate of the rotary slide body is positioned above the upper end of the support frame, thereby allowing the frame of the slide body to rotate freely.
[0006] However, the applicant of the present application has a demand for an article rotation mechanism that has a higher degree of freedom in the setting range within which the rotating slide body can move longitudinally and upwardly when moving longitudinally and upwardly of the frame body, and that can easily accommodate a variety of articles to be placed on it.

DETAILED DESCRIPTION OF THE INVENTION
[0025] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment for implementing a mounted article rotating mechanism according to the present invention will be described with reference to the drawings.
[0026] Fig. 1 is a perspective view of an article rotation mechanism according to an embodiment of the present invention, in which (a) shows a state in which the rotating slide is fixed to a support frame, (b) shows a state in which the rotating slide is slid upward and moved to a rotated position, (c) shows a state in which the rotating slide is rotated, (d) shows a state in which the rotating slide is rotated 180 degrees, and (e) shows a state in which the rotating slide is moved to its original fixed position and the article is rotated 180 degrees and fixed to a support frame.

[0027] In Figures 1 to 6, 10 indicates the article placement rotation mechanism of this embodiment, and the article placement rotation mechanism 10 comprises a rotating slide body 20 on which an article is placed and rotated, and a support frame 31 that supports the rotating slide body 20.
[0028] 2, the rotating slide body 20 is formed by fixing a rotating table 23 to the underside of a frame body 21 (frames 21a, 21b, 21c, and 21d) via an L-shaped steel material L and an upper plate 22, and rotatably attaching a lower plate 24 to the underside of the rotating table 23. The horizontal surfaces 21e and 21f of the two L-shaped cross-section frames 21a and 21c serve as mounting surfaces when the rotating slide body 20 is mounted on the support frame 31.
[0029] The rotating plate 23 is configured such that a rotating part having a number of steel balls (not shown) is interposed between the upper plate 22 and the lower plate 24, and the upper plate 22 and the lower plate 24 are rotated relatively around a rotating shaft 26 that passes through the center, and the rotating shaft 26 is fixed by a fixing member 29, and spacers 27, 28 are interposed between the rotating plate 23 and the upper plate 22 and the lower plate 24, respectively.
[0030] The rotating table 23 has the one side and the opposite side of the upper plate 22 fixed by bolts and nuts to steel members L, L fixed to the frame 21a and the inner surface of the frame 21c facing the frame 21a. At this time, the lower surfaces of the steel members L, L are fixed so as to be flush with the lower surfaces of the frames 21a, 21b, and therefore the upper plate 22 is attached so as to protrude downward from the lower surface of the frame body 21 by the amount of its thickness. Note that position indication marks M are provided on both side surfaces of the frame 21d to confirm the rotation position of the rotating slide body 20.
[0031] The support frame 31 is formed by assembling two steel members (frames 31a and 31c) with an inverted L-shaped cross section into a roughly rectangular shape by welding the longitudinal ends of the two steel members (frames 31b and 31d) together, and is fixed to the upper surface of the support leg 61 of the fixing member 60 as shown in Figures 3, 5 to 7.
[0032] On the other hand, swinging stays 40 are rotatably supported at the four corners on the back side of the lower plate 24. One end of the swinging stays 40 is rotatably fitted loosely to pins 42 arranged on L-shaped mounting brackets 41 attached to the four corners on the back side of the lower plate 24, and the other end is rotatably supported on a swinging shaft 43 installed between mounting bars 44, 44 installed in the longitudinal direction of support legs 61 of a fixture 60 that attaches the support frame 31 to the upper surface, and swinging of the swinging stays 40 enables the swinging slide body 20 to slide and rotate.
[0033] As shown in Figure 5, the oscillating stay 40 is positioned so that it is inclined at a predetermined angle with respect to the pivot axis 43 when the upper plate 22 of the rotatable slide body 20 is positioned to fit within the support frame 31 and the horizontal surfaces 21e, 21f of the frame 21c are placed on the horizontal pieces 31e and 31f, and the collision between the horizontal surfaces 21e, 21f of the frame 21c and the horizontal pieces 31e and 31f restricts the pivoting of one side and also prevents the rotation of the upper plate 22.
[0034] On the other hand, as shown in FIG. 6, the swing stay 40 causes the rotating slide body 20 to slide leftward while being raised upward from the fixed state, so that the upper plate 22 is positioned above the support frame 31 and the lower plate 24 is fitted into the support frame 31, restricting the co-rotation of the rotating slide body 20 and allowing the upper plate 22 of the rotating slide body 20 to rotate. A stopper ST limits the swinging movement of the rotary slide body 20 so that the rotary slide body 20 can be stopped. The stopper ST is formed of a pin-shaped member that protrudes inward of the frame body 31e and the frame body 31f that faces it.
[0035] Figures 1(a), 4(a) and 5 show the state in which the upper plate 22 of the rotating slide body 20 is fitted into and fixed in the support frame 31. In this state, the horizontal surfaces 21e and 21f of the frames 21a and 21c are placed on the horizontal pieces 31e and 31f of the frames 31a and 31c of the support frame 31, and the rotating slide body 20 is supported on the support frame 31, with the end of the upper plate 22 fitted into the support frame 31, and the rotating slide body 20 is placed on the support frame 31 so as not to be able to rotate relative to the support frame 31.
[0036] To rotate the upper plate 22 of the rotating slide body 20 from this state, the rotating slide body 20 is raised upward and slid to the left until it is moved to a position where its swing is restricted by the stopper ST. As shown in Figures 1(b), 4(b) and 6, the upper plate 22 is positioned above the upper surface of the support member 31, and the lower plate 24 is positioned below the upper end of the support frame 31, and the frame body 21 becomes rotatable relative to the support frame 31.
[0037] Then, as shown in Figure 1(c), the rotating slide body 20 is rotated, and in the rotated position (Figure 1(d)), the rotating slide body 20 is moved along the longitudinal direction of the support frame 31 to its original fixed position, and the horizontal surfaces 21e, 21f are placed on the horizontal pieces 31e and 31f, and with the rotating slide body 20 supported on the support frame 31, the end of the upper plate 22 is fitted into the support frame 31, and the rotating slide body 20 is placed on the support frame 31 so that it cannot rotate relative to the support frame 31.
[0038] The article rotation mechanism according to the present invention, having the above-described configuration, can be easily manufactured using commercially available steel members with a generally L-shaped cross section (angle members), rods, and a rotating table, and can be provided at low cost with a simple configuration. Furthermore, by simply changing the length and swing width of the swing stay, the movement distance of the swing slide body in the longitudinal direction and upward of the frame body can be adjusted, and an article rotation mechanism that can easily accommodate a variety of objects can be provided.
[0039] Fig. 7 is a plan view of the article rotation mechanism, (a) is a plan view showing a state in which the rotation slide body is fixed to the support frame, (b) is a plan view showing a state in which the rotation slide body has been slid upward and lifted to the rotation position. Fig. 8 is a schematic plan view showing a rotation state of the automobile seat rotation mechanism, (a) is a state in which the rotation slide body is fixed to the support frame, (b) is a state in which the rotation slide body has been slid upward and lifted to the rotation position, (c) is a state in which the rotation slide body has been rotated, (d) is a state in which the rotation slide body has been rotated, and (e) is a state in which the rotation slide body has been moved to its original fixed position.
[0040] 7 and 8 show the case where the article rotation mechanism 10 according to the present invention is used as a rotation mechanism for a seat in an automobile or train, and as shown in Fig. 6, a stay 41 is attached to the upper part of the rotating slide body 20 of the article rotation mechanism, and an automobile or train seat ST is attached to the stay. Support legs are attached to the lower four corners of the support frame 31 and are fixed to the floor of the automobile with bolts.
[0041] FIG. 8 is a diagram showing the rotational state of a seat ST in a car or train. First, the rotating slide body 20 of the article rotation mechanism 10 is fixed to the support frame 3 (the state shown in FIG. 1(a)), and the rotating slide body 20 is attached so as to be located at the center of the lower part of the seat ST (FIG. 8(a)). If an attempt is made to rotate the seat ST in this position, it will collide with the interior wall SW of the car or train and will not be able to rotate. Therefore, as shown in FIG. 8(b), the rotating slide body 20 is pulled in the direction of the arrow. This causes the seat ST to slide in the width direction of the car or train, creating a space between the seat ST and the interior wall SW of the car or train, and allowing the seat ST to rotate.
[0042] Then, as shown in Figure 8(c), it is rotated and fixed in a position facing the rear seat (Figure 8(d)), and the rotating slide body 20 is pushed back to its original position (the position in Figure 8(a)), thereby fixing the rotating slide body 20 so that it cannot rotate.
[0043] As described above, when the article rotation mechanism 10 according to the present invention is used as a rotation mechanism for a seat in an automobile or train, a rotation margin is formed between the inner wall SW and the seat ST, allowing rotation, making it suitable. Furthermore, because of its simple structure, it can be easily retrofitted to a completed vehicle.
[0044] In this embodiment, the rotating slide body 20 is formed by assembling the frame bodies 21 in a square shape, but the frame bodies 21 may be formed by assembling them in a rectangular shape, or the size of the frame bodies 21 may be formed to be approximately the same size as the support frame 31. Also, the rotating slide body 20 and the support frame 31 are formed from a substantially L-shaped member and a plate material, but are not limited to the above shapes, and various other modifications are possible, for example, they may be formed from a rectangular column material.
[0045] The present invention is not limited to being applied to automobile or train seats, but can also be used for various other objects, such as furniture. [Explanation of symbols]
