[0010]

[Mode of operation and use of device]

  Next, the operation of each device will be described as a mode of use of the direction-variable seat 100 adopting the same. At the same time, the sections will be described in detail, but before that, the direction variable seat 100 itself will be described. The operation will be described.

[0011]   In this variable orientation seat 100, as shown in FIG. 1 and FIG. The seat 10 is seated via a rotating mechanism 21 on a support base 20 fixed on the seat. The frame 11 is provided. In other words, the seat frame 11 of this seat 10 It is rotatable with respect to the support base 20 by a rotation mechanism 21. When the user performs the rotation operation, the foot pedal 22 provided on the support base 20 is used. The seat frame 11 is provided so as to be tiltable after the seat 10 is unfixed. It is performed by putting force on the seat back 12 and the like. Also the crew Alternatively, an operator remotely operates the seats 10 of the variable-direction seats 100 in the same direction all at once. When it is rotated by a rotary drive (not shown) housed in the support base 20. This is done automatically by the device.

[0012]   Then, the seat back 12 is attached to the seat frame 11 of the seat 10 in a reclamation manner. Inning is possible, and the back side of this seat back 12 is shown in FIG. As such, the table 30 is provided.

[0013]   ・ About automatic storage structure according to claim 1   When the user wants to use the table 30, the table 30 can be used as a seat back. Remove the stopper (not shown) that is fixed to the side of For the urging force of the spring 53 which is the urging device or the means 53 such as a fluid pressure spring. The table 30 is pulled to the front, that is, the table 30 is unfolded. This allows The table 30 is provided for the user located behind the variable direction seat 100 in which the table 30 is provided. The table 30 is located in the front, but the table 30 is located on both the left and right sides. Since it is supported by a parallel link 40 consisting of a pair of links 41, The table 30 pulled to the user side is in a horizontal state.

[0014]   When the table 30 becomes horizontal as described above, the parallel links 40 are formed. The operating device 52 connected to one of the linked links 41 operates to Parallel link 40 is locked to fixedly support table 30 in a horizontal position. It As a result, the user can use the table 30 in a stable state. .

[0015]   If the user wants to store the table 30 because he / she stands up, Release the locked state of the operating device 52 with the operating lever or foot lever To do. In addition, the crew or worker may change the traveling direction of the vehicle. , If you want to change the direction of each direction variable seat 100, use the main switch etc. By doing so, the locked state of the operation device 52 is released and the table 30 is collected all at once. Pay. That is, when the spring 51 is adopted as the urging device, , This spring 51 comprises at least one phosphorus which constitutes each parallel link 40. And act to pull the wheel 41 toward the seat back 12 side of the variable direction seat 100. And the state is held by the operating device 52. The state, that is, the locked state is released by operating the operating device 52. As a result, each parallel link 40 is stored on the seat back 12 side of the variable direction seat 100. It is done.

[0016]   The spring 51 is constructed as a so-called action spring. In this case, the operation device 52 does not have what is called a lock, and the link 41 is stored in the storage direction. It will be a tensioning device. In other words, when expanding the table 30, When the link 41 rotates beyond the so-called top dead center, it comes into contact with a stopper (not shown) and Position is held by the spring 51 and the action of the spring 51 is prevented. The one that pulls the link 41 in the storage direction can be the operation device 52 referred to here. It is something. In addition, depending on how the spring 51 is used as the urging device, Therefore, the configuration and operation of the operating device 52 are different from each other.

[0017]   If a means 53 such as a fluid pressure spring is adopted as the urging device, become that way. That is, the means 53 such as a fluid pressure spring is enclosed in the cylinder. The piston rod is always extended or contracted by the action of the pressurized fluid. The pressure fluid is applied to the piston rod in the opposite direction to the biasing direction of the piston rod. The bull 30 is configured to be developed. And this seat back The movement of the piston rod 12 is regulated by the operating device 52. When operating the operating device 52, at least the respective parallel links 40 are configured. One link 41 is stored on the seat frame 11 side of the variable direction seat 100. It is structured like this. Therefore, the operating device for storing the table 30 When 52 is actuated, the action of the pressure fluid in the means 53 such as the fluid pressure spring is achieved. Therefore, the table 30 is stored in the storage position.

[0018]   Further, when an electric motor is used as the urging device, for example, the operating device 52 Will correspond to that switch. In this case, for example, a ball screw Is carried out by driving the table with an electric motor. The storage and the storage are performed by appropriately changing the rotation direction of the electric motor.

[0019]   What is important when storing this table 30 is this table 30 and this The parallel links 40 that support the back of the seat back 12 of the direction-variable seat 100 are That is, it is stored without forming a protruding portion on the surface side. In this respect, the present invention Then, the left and right sides of the table 30 are formed into a parallel link 40 including a pair of links 41. Therefore, I support it, so there is no problem. That is, the table at the time of expansion 30 has a predetermined angle with respect to the parallel link 40 that supports it and is horizontal. The parallel links 40 of the variable direction seat 100 are maintained. By tilting toward the seat back 12 side, as shown in FIG. 1 and FIG. The table 30 forms a straight line with each parallel link 40. to this As a result, the table 30 fits on the back side of the seat back 12 when stored. It will be in close contact, and there will be no part protruding from the variable orientation seat 100. Of. This is shown in FIG. 4 by means of each parallel link 40 on the table 30. The parallel links 40 constituting each parallel link 40 are connected to each other. Since they do not interfere, it is natural that no problems will occur.

[0020]   As described above, the expanded table 30 is operated by the user's arbitrary operation. In addition, the seat back 1 of the direction-variable seat 100 can be operated by a simultaneous operation by crew members. It is stored on the second side. As a result, the expanded table 30 is a sheet The rotation of 10 does not get in the way, so crew or workers can move in each direction. The direction of the odd seats 100 can be changed all at once.

[0021] ・ About automatic storage structure according to claim 2   Next, the operation of the automatic storage structure according to claim 2 will be described. In the structure, in place of the parallel link 40 adopted in claim 1, The support arm 60 and the table control member 61 such as a wire guided by the support arm 60 The difference is that it is adopted. That is, the table 30 of each support arm 60 The table 30 is supported at the tip, and the table 30 is expanded as the support arm 60 tilts. Alternatively, the storage is performed similarly to the automatic storage structure according to claim 1, and The spring 51 or the fluid pressure spring in which the tilting motion of the support arm 60 is an urging device. Such as a means 53 or an electric motor for locking the deployed position or The release is performed by the operation device 52, as described above.

[0022]   In the automatic storage structure according to claim 2, the table 30 at the time of unfolding is in a horizontal shape. The table 30 is a seat of the direction-variable seat 100 during storage Being in close contact with the back surface of the back 12, that is, tilting of each support arm 60. Table control for adjusting the angle of the table 30 connected to this according to What is done by the member 61 is different from the automatic storage structure of claim 1 above. Is.

[0023]   That is, first, the table 30 in this case has a table as shown in FIGS. The tip of the cable control member 61 is tiltably supported by a connecting pin 62. Therefore, as shown in FIG. 5, the support arm 60 is attached to the rear direction variable seat 100. If the user tilts, the table control member 61 does not work. The table 30 becomes horizontal due to its own weight. Of course, this table 30 is a guide member 63 guided by an elongated hole 64 formed on the support arm 60 side. Since the guide member 63 is engaged with one end of the long hole 64, The horizontal state of the table 30 is maintained.

[0024]   Here, in order to store the table 30, each support arm 60 is attached to the direction variable seat 10. When the seat back 12 of 0 is tilted, the spring 65 is pulled as shown in FIG. Table springs such as wires connected to the spring 65 The control member 61 is pulled downward in the drawing, and the table 30 is shown in FIG. It stands up as shown, that is, it is straight with respect to the support arm 60. . Accordingly, if the support arm 60 is tilted to the seat back 12 side, the table 30 is closely attached to the back side of the seat back 12. In addition, this The cable control member 61 is guided to the support arm 60, and It does not touch or interfere with the material.

[0025]

【Example】

  Next, the invention according to each claim will be described separately by referring to the drawings. Before that, we will discuss the parts common to each device, that is, the configuration of the variable direction seat 100 itself. It will be described with reference to FIGS. 1 and 2.

[0026]   The direction-variable seat 100 is mounted on a support base 20 that is fixed on the floor of the vehicle so that it can rotate. It has a seat frame 11 that is rotatably assembled through a mechanism 21. Yes, the seat 10 is provided on the seat frame 11, and the seat back is also provided. 12 are supported so that they can recline. In addition, this seat back 12 The lining is performed by operating the operation lever provided on the armrest plate 13 or the like. Although the seat frame 11 is normally fixed to the support 20, The release of the lock is used by operating the foot pedal 22 provided on the support base 20. It is done by the user.

[0027]   Further, in the direction-variable seat 100, in order to rotate the seat 10. A drive source such as an electric motor is provided in the rotating mechanism 21 of FIG. It can be done by remote control. In other words, each direction variable seat 100 Of the seat frame 11 supporting the seat 10 of the It is designed so that the staff can do it all at once in one place.

[0028]   Then, on the back side of the seat back 12 of each direction variable seat 100, behind the seat back 12. The table 30 for use by the user of the directional seat 100 located is taken out. Since the table 30 in this embodiment is provided freely, It can be taken out by rotating the stopper provided on the I can do it. In this case, the parallel support for supporting the table 30 will be described later. Use this table 30 regardless of the position of the link 40 or support arm 60 However, each parallel link 40 or support arm 60 may be tilted toward the user. It is natural that the person who moves the table 30 can use the table 30 in a natural posture.

[0029] ・ About automatic storage structure of claim 1   The automatic storage structure for the table 30 according to claim 1 is as shown in FIGS. As shown, the table 30 is supported on the seat frame 11 side of the direction-variable seat 100. The parallel link 40, which consists of two links 41 on the left and right, is adopted as ing. That is, each parallel link 40 has a taper at its upper end, as shown in FIG. The right and left sides of the bull 30 are connected to each other. As shown in FIG. 3, the lower end is tiltably connected to the back side of the seat frame 11. It is a thing. Of course, the links 41 forming each parallel link 40 are also shown in FIG. As shown, the position in the left-right direction is shifted, and The hooks 41 are arranged so as not to interfere with each other when they are tilted.

[0030]   At least one of the parallel links 40 configured as described above One link 41 is provided with means 53 such as a spring 51 or a fluid pressure spring. The urging device is connected to the urging device on the seat frame 11 side of the seat 10. It is provided. That is, in the direction-variable seat 100, each parallel ring is Automatically and forcibly tilting the hook 40 to the back side of the seat back 12, that is, It is necessary to store the table 30 and the parallel link 40 on the seat back 12 side. However, for this reason, each parallel link 40 is biased toward the seat back 12 side by the biasing device. I am trying to do it. As this urging device, there are various A mode is conceivable, but in any case, the position of each parallel link 40 is fixed. An operating device 52 for operating the operating device 52 is required, and the operating device 52 is operated by remote control. It has to be something that can be created.

[0031]   A spring 51 can be used as the urging device, but in this case, this One end of each spring 51 of at least one of the parallel links 40 is It is connected to the link 41. Of course, this spring 51 is a so-called tension spring. It is convenient to use a pulling, and in such a case, the link Connect this spring 51 to the upper side of the support shaft for the frame 11. It is natural to do so. When using this spring 51, Is a so-called action spring, the configuration of the operating device 52 can be simplified. It is possible. That is, each parallel link 40 that makes the table 30 horizontal If it is made to exceed the so-called top dead center, it will be parallel to the action of this spring 51 itself. What can hold the horizontal state of the table 30 by a stopper for the link 40 In that case, the configuration of the operating device 52 is as follows. Just configure the parallel link 40 beyond the dead center to return to the top dead center or later. It becomes a good thing.

[0032]   The operation device 52 when the spring 51 is adopted as the urging device is shown in FIG. As shown in FIG. 5, the link 41 is configured to be engaged with the lower end of the link 41. In fact, the lock can be released by remote control. For example , This operating device 52 is a ball driven by an electromagnetic lock or an electric motor. Various things such as screws and fluid pressure springs that use pressurized fluid are adopted. In any case, all the operation devices 52 of the multiple variable direction seats 100 are simultaneously operated. It is necessary to be able to operate. In that respect, the electromagnetic lock also operates due to its configuration. The above is also very advantageous, and the operation of the individual variable direction seat 100 is easy. It will be.

[0033]   On the other hand, means 53 such as a fluid pressure spring can be adopted as the urging device. The means 53 such as a fluid pressure spring is a cylinder in which a pressure fluid is sealed. In contrast, by controlling the flow of pressure fluid, the piston rod expands and contracts. It is configured as follows. When this means 53 such as a fluid pressure spring is adopted Also, each parallel link 40 is attached to the seat back 12 side of the variable direction seat 100. It is advantageous to keep it active. The reason is that a plurality of variable direction seats 100 It is easy to store each table 30 on the seat back 12 side at once. Because it can be done. Of course, when the seat back 12 is adopted, Of course, a spring 51 like The means 53 such as a ring also has a mechanism for fixing the position of the piston rod. Therefore, the operating device 52 need not be provided with this fixing mechanism. It That is, as the operating device 52, the piston of the means 53 such as a fluid pressure spring is used. It is sufficient that the rod is allowed to move, so-called locking mechanism. It is not necessary to have.

[0034]   Furthermore, the best operability of this urging device is that it is driven by an electric motor. It is to adopt a ball screw that is driven. This electric motor and ball screw are Both of them are a lock device and a release device thereof, that is, a biasing device that also serves as the operating device 52. It will be easy to do.

[0035] ・ About automatic storage structure of claim 2   In this automatic storage structure, the biasing device according to claim 1 is common, Although it has a structure as described above, it is used for supporting the table 30. Claimed to be composed of the holding arm 60 and the table control member 61. It is different from the automatic storage structure according to item 1.

[0036]   That is, the automatic storage structure according to claim 2 is as shown in FIGS. The left and right sides of the table 30 are connected to the upper ends of the pair of left and right support arms 60. The support arms 60 are rotatably connected to each other via The lower end is tiltably connected to the seat frame 11 side of the variable direction seat 100. Of. In particular, in the embodiment shown in the drawings, the length of the tip of each support arm 60 is long. This is a long hole that uses a fixed bracket with a hole 64. The guide member 63 fixed to the table 30 side is housed in 64 so as to be guided. is there. In other words, the support arm 60 in this embodiment has the elongated hole 64 for the support arm 60. The guide member 63 on the cable 30 side is configured to be guided within a predetermined range. This allows the table 30 to rotate within the range of the state shown in FIG. 5 or 6. It is something that is allowed.

[0037]   The table control member 61 is made of wire in this embodiment. However, it is made of a material or member that is flexible and does not expand or contract. Anything can be used as long as it is done. In addition, this table control member 61 Needs to be guided and supported by the support arm 60 because the reason is At the same time that the table control member 61 tilts together with the support arm 60, If not guided by the holding arm 60, the table control member 61 will interfere. This is because the tilting of the support arm 60 is hindered. So In the sense of FIG. 5, the table control member 61 is attached to the support arm 60 in FIG. An example in which the table is supported outside the table is shown, but the table control member 6 It is advantageous to thread 1 into the support arm 60.

[0038]   The upper end of the table control member 61 is connected to the table 30 side. The connection position of the support arm 60 and the table is shown in FIG. When the bull 30 becomes linear, the upper end of the table control member 61 Indicates the left side of the connecting pin 62 connecting the table 30 to the support arm 60 in the drawing. It is arranged so as to be located on the side where the table 30 is stored. Also this table The lower end of the control member 61 is located on the seat frame 11 side of the variable direction seat 100. It is connected to the connected spring 65, and this spring 65 and the table The support arm 60 to the seat frame 11 It is located below the pivoting shaft. Especially, this table control part The material 61 has its connecting point with the spring 65 always located below the pivot. Is guided to.

[0039]   The table control member 61 is configured as described above, and the table 3 No. 0 support arm 60 is connected to the guide member 63 on the table 30 side and the support arm 60. Since it is performed by engaging with the long hole 64 provided in the If it is tilted to one side, the table 30 will be level as shown in FIG. 5 for the user behind. The supporting arms 60 are connected to the seat back 1 of the variable direction seat 100. If it is stored on the 2 side, the urging force of the spring 65 will control the table. The table 30 is transmitted to the table 30 via the member 61, and the table 30 stands up. It becomes a straight line with respect to 60, and the seat back 12 side of this table 30 is accommodated. Delivery is guaranteed.

[0040]   Further, in the embodiment shown in FIGS. 5 and 6, the lowermost end of each support arm 60 is The biasing device is connected to the spring 51 or the fluid. What is constituted by means 53 such as a pressure spring is that the above-mentioned claims It is similar to the automatic storage structure according to Item 1.

[0041]
