Description

  The present invention relates to a drawer storage mechanism for a table provided on a seat of a vehicle such as a railway, a ship, an aircraft, or a bus.

  Vehicles such as railways, ships, airplanes, and buses have a table 5 that is stored in the armrest 3 when not in use and pulled out from the armrest 3 when in use and held horizontally as shown in FIGS. The sheet | seat 1 which has is provided. In the armrest 3, a hinge means 9 is engaged along a vertical linear guide 7 so as to be movable in the vertical direction (the arrow C direction and the counter arrow C direction in FIGS. 6 and 7). A slit 11 into which the table 5 can be inserted is formed on the upper surface of the armrest 3. Further, on the upper surface of the armrest 3, an elbow rest 13 that can conceal / open a part of the slit 11 is provided.

  The hinge means 9 enables the table 5 to rotate in the front-rear direction (in the direction of arrow D and the direction of the opposite arrow D in FIGS. 6 and 7) about the width-direction axis of the seat 1 and The table 5 is rotatable at the center in the horizontal direction (the direction of arrow E and the direction of counter arrow E in FIG. 6).

  Furthermore, in the armrest 3, when the table 5 is pulled out from the armrest 3, when the table 5 is housed in the armrest 3, the locking means 21 that prohibits the downward movement of the hinge means 9 in conjunction with it. An unlocking means 23 for releasing the locking means 21 is provided.

  The operation of such a configuration will be described. In a state where the table 5 is stored in the armrest 3 (the solid line table 5 in FIG. 7), the front portion of the table 5 is exposed to the outside from the slit 11. When the portion F exposed to the outside of the table 5 is pulled upward, the hinge means 9 moves linearly in the direction of the arrow C along the guide 7, and in FIGS. It becomes the state of. At this time, the elbow rest 13 for concealing the slit 11 is pushed by the table 5 and opened. Further, the lock means 21 is activated, and the downward movement of the hinge means 9 is prohibited.

  Here, the table 5 in the 5D state is tilted forward (in the direction of the arrow D) to be in the 5B state via the 5A state. Next, the table 5 in the 5B state is tilted in the horizontal direction (arrow E direction) to bring the table 5 into a usable state 5C.

Conversely, to put the table 5 in the used state into the storage state, the table 5 in the state 5C is rotated in the counter arrow E direction, and then rotated in the counter arrow D direction to be in the state 5A. Here, the unlocking means 23 unlocks the locking means 21, and the table 5 is moved in the direction of the opposite arrow C to enter the housed state (for example, see Patent Document 1).

However, the table storing and storing mechanism having the above configuration has the following problems.
(1) In order to put the table 5 in the housed state into use, an operation of pulling up the table 5 linearly (operation in the direction of arrow C) and an operation of tilting the table 5 forward (operation in the direction of arrow D) The three operations of moving the table 5 horizontally (the operation in the direction of arrow E) are necessary, and the operation is troublesome.
(2) Since the lock means 21 and the lock release means 23 are necessary, the structure is complicated and the cost is high.
(3) When the table 5 in the 5D state in which the F portion of the table 5 is pulled up with the left hand is rotated to the 5B state via the 5A state, the table 5 hits the elbow and it is difficult to operate with one hand.
(4) When the table 5 in the 5D state is rotated to the 5B state through the 5A state, the table 5 is in the 5B state due to the weight of the table 5 from the middle. bad.

  The present invention has been made in view of the above-mentioned problems, and a first object thereof is to provide a table drawer storage mechanism having good operability.

  A second problem is to provide a low-cost table drawer storage mechanism with a simple configuration.

  The third problem is to provide a table drawer storage mechanism with good usability.

The invention according to claim 1, which solves the above problem, is a table drawer storage mechanism that is stored in the armrest when not in use and pulled out from the armrest during use and is held horizontally.

The recess 115b is provided with a second hinge 117 in which a hole 117a is formed. The second hinge 117 is inserted through the hole 115c of the first hinge 115, the hole 117a of the second hinge 117, and the hole 115d of the first hinge 115. The second hinge 117 is rotatably provided on the first hinge 115 by the shaft 123 made. The hinge receiver 113, the first hinge 115, and the shaft 121 constitute a vertical rotation unit that rotates the table 103 in the vertical direction. The first hinge 115, the second hinge 117, and the shaft 123 constitute the table 103. The horizontal direction rotation part which rotates the horizontal direction is comprised.

  Further, the side surface 117a of the second hinge 117 comes into contact with the bottom surface of the concave portion 115b of the first hinge 115, so that the table 103 is in a substantially horizontal state, and further rotation of the table 103 is prohibited.

  An elbow rest 131 capable of concealing / opening the slit 105 is attached to the upper surface 101 b of the armrest 101 via a hinge 133. The rotating shaft of the hinge 133 is provided with a spring (biasing means) 135 that urges the elbow rest 131 in a direction to conceal the slit 105. Further, the armrest 131 is provided with a hinge base 137 made of stainless steel or the like at a position where the table 103 taken out from the armrest 101 can come into contact (table holding means).

  In the armrest 101, there is provided a stopper 145 made of an elastic body (for example, rubber) that prohibits the stored table 103 from rotating further back.

The first hinge 115 has an arm portion 115e. A hinge means is provided by a gas spring 143 having one end rotatably attached to the armrest 101 via the bracket 141 and the other end rotatably attached to the arm portion 115e of the first hinge 115. The first hinge 115 of 111 is biased. In this embodiment, when the table 103 is housed in the armrest 101, the urging force that the table 103 presses against the stopper 145 is applied to the first hinge 115 of the hinge means 111, and the table 103 is removed from the armrest 101. The urging force that rotates the table 103 upward is set to be applied to the first hinge 115 of the hinge means 111. Furthermore,
Next, the operation of “the above configuration” will be described with reference to FIGS.

  In the stored state shown in FIG. 2, the front portion of the table 103 is exposed to the outside through the slit 105 of the armrest 101. In this state, the table 103 is pressed against the stopper 145 by the urging force of the gas spring 143. Then, when the table 103 is pulled out while rotating upward, the table 103 presses the elbow rest 131 that conceals the slit 105 to open the elbow rest 131 (rotate toward the open state). Exceeding the state shown in FIG. 3, the gas spring 143 provides an urging force that rotates the table 103 upward to the first hinge 115 of the hinge means 111 and assists the operating force that rotates the table 103 upward.

  When the table 103 is further rotated upward, when the state shown in FIG. 4 is exceeded, the pressing of the table 103 on the elbow rest 131 is released, and the elbow rest 131 is slit by the biasing force of the spring 135 as shown in FIG. 105 returns to the concealed state, and the first hinge 115 of the hinge means 111 can come into contact with the hinge base 137 on the upper surface thereof.

To do. Then, the table 103 is rotated in the horizontal direction to be brought into use.

  To store the used table 103, the horizontal table 103 is raised to the state shown in FIG. Then, the first hinge 115 of the hinge means 111 of the table 103 is moved away from the hinge base 137 of the armrest 131 so as to be in the state shown in FIG. Here, the elbow rest 131 is opened, the table 103 is rotated downward, and the storage state shown in FIG. 1 is obtained.

According to such a configuration, the following effects can be obtained.
(1) Since the table 103 is pulled out from the slit 105 on the front surface of the armrest 101 while being rotated upward, the table 103 in the stored state is placed in the use state. There are only two operations, that is, an operation of pulling out from the slit 105 on the front surface of the armrest 101 while rotating upward, and an operation of rotating the table 103 in the horizontal direction to make it usable.
(2) From the front surface to the upper surface of the armrest 101, a slit 105 through which the table 103 can be inserted, a vertical rotation unit that rotates the table 103 in the vertical direction, and a horizontal rotation unit that rotates the table 103 in the horizontal direction The hinge means 111 and the table holding means (elbow rest 131) that prohibits the table 103 taken out from the armrest 101 from rotating downward are simple in structure and low in cost.
(3) By providing the biasing means (gas spring 143) for biasing the first hinge 115 of the hinge means 111, a biasing force having a desired magnitude in a desired direction can be applied to the table 103.
(4) A stopper 145 is provided in the armrest 101 to prohibit the table 103 in the stored state from rotating further, and the urging means (gas spring 143) is in a state where the table 103 is stored in the armrest 101. Then, the urging force that the table 103 presses against the stopper 145 is applied to the first hinge 115 of the hinge means 111, so that the table 103 in the stored state is pressed against the stopper 145 and the vehicle or the like on which the seat is provided vibrates. The table 103 can be prevented from being exposed in the armrest 101.
(5) When the table 103 is taken out from the armrest 101, the urging means (gas spring 143) applies an urging force that rotates the table 103 upward to the first hinge 115 of the hinge means 111.
When rotating 3 upward, a large operating force is not required and the feeling of use is good.
(6) Since the elbow rest 131 is a table holding means, the configuration is simple.
(7) By providing the hinge 133 with a spring (biasing means) 135 that urges the elbow rest 131 in the direction of concealing the slit 105, when the stored table 103 is rotated upward, the table 103 is The armrest 131 in the concealment state is pressed and moved toward the open state. When the table 103 is further rotated upward and the pressure on the elbow rest 131 of the table 103 is released, the elbow rest 131 returns to the state of concealing the slit 105 by the biasing force of the spring (biasing means) 135, The first hinge 115 of the hinge means 111 can come into contact with the upper surface. Therefore, operability is good.
