Description

  The present invention relates to a support mechanism for a lid that closes the openings of various storage bodies or storage portions.

  There is a lid opening / closing device that maintains a closed state by a latch device and opens the lid by biasing of a spring when the lock by the latch device is released. (See Patent Document 1)

However, in such an opening / closing device, the lid enters a rotational motion at the same time as the lock is released, and the opening is opened by this rotational motion. Therefore, the front surface (design surface) of the main body provided with the opening rotates the lid. On the other hand, when the lid is not flat, it is necessary to provide a large space for the lid to escape during the rotational movement.
JP-A-6-77671

  The main problem to be solved by the present invention is that it is difficult to interfere with the front surface of the main body having the opening as much as possible when opening the lid that closes the opening of various storage bodies or the storage section (main body). The point is to move smoothly.

In order to solve the above problems, in the present invention, the lid support mechanism has the following configurations (1) to (8).
(1) The lid that closes the opening is slid forward from the closed position, and then rotated from the slide movement end position so that the opening is opened at the rotation end position. A supporting mechanism for supporting,
(2) a base body fixed to the main body provided with the opening;
(3) a slide body combined with the base body so as to be movable back and forth;
(4) A rotating body having a lid support portion at the front end and rotatably assembled to the slide body, and having a posture control unit behind the rotating assembly position;
(5) biasing means for constantly biasing the rotating body in a direction to rotate the rotating body toward the rotation end position;
(6) The base body is formed with a guide wall along the moving direction of the slide body,
(7) The posture control unit of the rotating body is pressed against the guide wall by the urging means.
(8) At the forward end position of the slide body where the lid body is positioned at the slide movement end position, the posture control unit comes out earlier than the front end of the guide wall.

  According to such a configuration, until the slide body reaches the forward end position, the urging means that urges the rotating body that supports the lid body at the two positions of the rotation assembly position on the slide body and the posture control unit. The lid body can be supported so as not to cause the rotation toward the rotation end position. First, the lid body at the closed position can be slid forward to the slide movement end position. After this, when the slide body reaches the forward end position, the posture control unit comes out ahead of the front end of the guide wall, so that the rotary body is supported only at the rotary assembly position with respect to the slide body. The rotating body is rotated toward the rotation end position by the urging force of the urging means. By this rotation, the lid body at the slide end position is rotated to the rotation end position. As a result, it is possible to make it difficult to cause interference between the lid and the front surface of the main body including the opening in the opening operation of the lid, and in selecting the shape of the front surface of the main body including the opening and the shape of the lid, There is no need to pay special attention to such interference.

  The slide body extends along a movement trajectory drawn by the posture control unit by turning toward the turning end position of the turning body by the biasing of the biasing means, and one end of the groove is abutting part of the posture control unit. In some cases, a through groove of the posture control unit is formed.

  In this case, since one end of the through groove is the abutting portion, the rotation of the rotating body can be performed by causing the posture control unit to abut against the abutting portion by the urging means. The lid can be stably positioned at the rotation end position.

The support mechanism includes a biasing unit that constantly biases the slide body in a direction to advance the slide body toward the forward end position,
A latch body provided on one of the slide body and the base body;
The other side of the slide body is engaged with the latch body against the urging force at the retracted position of the slide body which positions the lid body at the closed position, and the front surface of the lid body at the closed position is used. There is a case in which a latch device is provided which includes a latching body which is released by the pushing operation of the slide body and is engaged again by pushing the slide body at the forward end position back to the backward position.

  In such a case, the slide body is automatically moved to the forward end position by urging the urging means by releasing the engagement between the engagement body and the latch body by pushing the front surface of the lid body in the closed position. In addition, by pushing back the slide body at the forward end position to the backward position, the latch body and the latch main body are again engaged with each other, and the slide body is moved to the backward position against the bias of the biasing means. The state in which the lid is in the closed position can be stably maintained again.

  Either one of the slide body and the base body is engaged with a locked portion formed on the other of the slide body at a forward end position of the slide body by an elastic force, and the slide body is pushed back toward the retracted position. In some cases, a lock body configured to release this engagement may be provided.

  In this case, at the forward end position of the slide body, the slide body from the forward end position to the backward position so that the slide body does not move unexpectedly from the forward end position to the backward position. Such a slide body can be temporarily held in a state in which the push-back operation can be performed.

  The support mechanism may be provided with a braking unit that applies braking to the rotation toward the rotation end position of the rotating body by the urging of the urging unit.

  In this case, it is possible to prevent the cover body from rotating vigorously from the slide movement end position to the rotation end position by urging the urging means. A high-class feeling can be given.

  According to the present invention, the opening operation of the lid can be performed by once sliding the lid forward and then rotating, so that the lid does not easily interfere with the front surface of the main body having the opening. The lid can be moved smoothly to make such an opening.

  The best mode for carrying out the present invention will be described below with reference to FIGS.

  Here, FIGS. 1 and 2 show the components constituting the support mechanism according to the embodiment as separated from each other, and FIGS. 3 to 5 show that the lid R is in the closed position. Accordingly, FIGS. 6 to 8 show a state in which the slide body 2 constituting the support mechanism is in the retracted position, and FIGS. Thru | or FIG. 11 has each shown the state in which the cover body R exists in a rotation completion position.

The latch body 601 provided on the slide body 2 is engaged with the latch body 601 in the retracted position (position in FIG. 3) of the slide body 2 that positions the lid R at the closed position, against the bias, and the closed position. This engagement is released by the pushing operation of the slide body 2 using the front surface of the lid R in (i.e., release push), and the slide body 2 at the forward end position (position in FIG. 6) is pushed back to the backward position again. And the hook 602 to be hooked again (that is, hook push).
A latch device 6 is provided.

  In the example shown in the drawing, a fastening portion 110 at the front end of the tension coil spring 500 is formed on the inner surface of the one side plate 101 of the base body 1 and in the vicinity of the opening portion 100. On the first surface 201 side of the substrate 200, on the rear end side of the substrate 200, a retaining portion 205 of the spring trailing end of the tension coil spring 500 is formed, and both the retaining portions 110 and 205 are used. Thus, the slide body 2 is constantly urged toward the forward end position by a tension coil spring 500 interposed between the base body 1 and the slide body 2. That is, in the illustrated example, the tension coil spring 500 functions as the urging means 5.

  In the illustrated example, the latch body 601 is attached to the inner surface of the back plate 104 of the base body 1, and the engaging body 602 is formed at the rear end of the slide body 2.

  In the illustrated example, the engaging body 602 is formed so as to protrude rearward from the rear end of the slide body 2. This engaging body 602 has a head 602a, a neck 602b, and a jaw 602c that is an engaging portion. On the other hand, the latch body 601 is configured to have a rectangular tube shape that receives the latch body 601 from the cylinder front end opening Ha at the retracted position of the slide body 2. A latch mechanism (not shown) configured to be engaged with the engagement body 602 so as to hold the head 602a of the engagement body 602 and to release the engagement at the time of the release push is incorporated.

  Thereby, in this embodiment, the slide body 2 is released by the urging force of the urging means 5 by releasing the engagement between the engagement body 602 and the latch body 601 by pushing the front surface of the lid R in the closed position. Can be automatically moved to the forward end position, and by pushing back the slide body 2 at the forward end position to the backward position, the engaging body 602 and the latch main body 601 are engaged again and energized. The state in which the slide body 2 is in the retracted position against the bias of the means 5, that is, the state in which the lid R is in the closed position can be stably maintained again.

  In this embodiment, the base body 1 is engaged with the locked portion 206 formed on the slide body 2 by impact at the forward end position of the slide body 2, and the slide body 2. There is provided a lock body 111 configured to release this engagement by pushing back toward the retracted position.

In the example shown in the figure, the lock body 111 is provided at the upper part of the base body 1 on the open part 100 side. Specifically, in the illustrated example, the lock body 111 has a rotating shaft 111c at the rear end, and the rotating shaft 111c is moved up and down around the rotating shaft 111c. A main body 111a rotatably attached to the base body 1;
The main body 111a is wound around the rotation shaft 111c, one end of the spring is fixed to the base body 1, and the other end of the spring is fixed to the main body 111a so that the front end of the main body 111a is always downward. It is comprised from the torsion coil spring 111d urged | biased in the direction to push down.

  Further, in the example shown in the figure, the locked portion 206 is a through hole 206a having a size that allows the front end of the main portion 111a of the lock body 111 formed on the front end side of the upper plate portion 204 of the slide body 2 to enter. It is configured as.

  In the illustrated example, the front end 111b of the main portion 111a of the lock body 111 is provided on the outer surface of the upper plate portion 204 of the slide body 2 during the period from the retreat position of the slide body 2 to the advance end position. Is constantly pressed by the action of the torsion coil spring 111d, and the slide body 2 is slid while the outer surface of the upper plate portion 204 is slidably contacted with the front end 111b of the main body portion 111a. When moved to the forward end position, the front end 111b of the main portion 111a of the lock body 111 enters the through hole 206a by the action of the torsion coil spring 111d. When the slide body 2 is pushed back from the forward end position toward the backward position, the front end 111b of the main portion 111a of the lock body 111 is lifted against the bias of the torsion coil spring 111d by the hole front edge 206b of the through hole 206a. The engagement between the lock body 111 and the locked part 206 is released.

  Thereby, in this embodiment, at the forward end position of the slide body 2, the forward end position is set so that the slide body 2 does not move unexpectedly from the forward end position toward the backward position. Thus, the slide body 2 can be temporarily held in a state in which the push-back operation of the slide body 2 toward the retracted position is enabled.

(Rotating body 3)
The rotating body 3 has a support portion 300 that is attached to the back surface of the lid R at the front end portion and supports the lid R, and is rotatably assembled to the slide body 2. An attitude control unit 303 is provided behind the position 301.

  In the illustrated example, the rotating body 3 is rotatably attached to the slide body 2 so that one surface thereof faces the second surface 203 of the substrate 200 of the slide body 2.

  Specifically, the rotating body 3 has a shaft portion 302 that is inserted into a shaft hole 207 formed in the upper corner portion of the front end side of the substrate 200 of the slide body 2 on one surface side thereof.

  The rotating body 3 has the support portion 300 in front of the shaft portion 302 and below the shaft portion 302 at a pre-rotation position (position in FIG. 6). Further, at the position before the rotation, the posture control unit 303 is provided at a position substantially at the same level as the shaft portion 302 and at the rear of the shaft portion 302. In the illustrated example, the posture control unit 303 is configured to have an axial shape protruding from one surface side of the rotating body 3. The posture control unit 303 is moved on a virtual circular arc whose radius is the pitch between the shaft unit 302 and the posture control unit 303 by the rotation of the rotating body 3 around the shaft unit 302. However, in the illustrated example, a through groove 208 having a split groove shape along the arc is formed in the slide body 2, and the posture control unit 303 is formed on a guide wall 112 a of the base body 1 described later through the through groove 208. The tip side is pressed. In addition, an edge portion that is directed rearward at the position before rotation in the rotating body 3 is formed along a virtual circular arc centering on the shaft portion 302, and a rack 304 is provided on the edge portion. Is formed.

  In the illustrated example, the rotating body 3 rotates so as to lift the support portion 300 upward from below from the pre-rotation position (position in FIG. 6) toward the rotation end position (position in FIG. 9). It comes to be moved.

(Biasing means 4)
The urging means 4 is configured to constantly urge the rotating body 3 in a direction in which the rotating body 3 is rotated toward the rotation end position.

  In the illustrated example, the biasing means 4 is wound around the shaft portion 302 of the rotating body 3, and one end of the spring is fixed to the slide body 2, and the other end of the spring is fixed to the rotating body 3. The torsion coil spring 400 urges the support portion 300 of the rotating body 3 to always lift upward.

(function)
The base body 1 is formed with a guide wall 112a along the moving direction of the slide body 2,
The posture control unit 303 of the rotating body 3 is brought into pressure contact with the guide wall 112 a by the urging force of the urging means 4.

  In the illustrated example, a linear guide groove 112 extending along the front-rear direction of the base body 1 is formed on the inner surface of the one side plate 101 of the base body 1. The groove wall below the linear guide groove 112 functions as the guide wall 112a.

  In this embodiment, the posture control unit 303 comes out earlier than the front end 112b of the guide wall 112a at the forward end position of the slide body 2 that positions the lid R at the slide movement end position. It has become. In the example shown in the figure, a guide groove 113 extending downward by communicating the groove upper end with the groove front end of the linear guide groove 112 is further formed on the one side plate 101 of the base body 1 and is ahead of the front end 112b of the guide wall 112a. After that, the attitude control unit 303 that has moved out of this position enters the guide groove 113 and is moved along the guide groove 113 by the rotation of the rotating body 3.

  Further, in this embodiment, the slide body 2 extends along the movement locus drawn by the attitude control unit 303 by the rotation toward the rotation end position of the rotation body 3 by the urging means 4. In addition, a through groove 208 of the posture control unit 303 is formed in which one end of the groove (the lower end of the groove in the illustrated example) is an abutting portion 208a of the posture control unit 303. At the forward end position of the slide body 2, the upper end of the through groove 208 is positioned in front of the front end 112b of the guide wall 112a, and the through groove 208 and the guide groove 113 extend in the vertical direction. Alignment is made so that they are substantially in communication. (Fig. 10)

  Thereby, according to the support mechanism of the lid R according to this embodiment, the rotating body 3 that supports the lid R is rotated to the slide body 2 until the slide body 2 reaches the forward end position. It can be supported so as not to cause the rotation toward the rotation end position against the urging of the urging means 4 at the two positions of the dynamic assembly position 301 and the posture control unit 303, and first the lid in the closed position The body R can be slid forward to the slide movement end position. Thereafter, when the slide body 2 reaches the forward end position, the posture control unit 303 comes out of the front end 112b of the guide wall 112a, so that the rotary body 3 is supported only at the rotary assembly position 301 with respect to the slide body 2. Thus, the rotating body 3 is rotated toward the rotation end position by the urging force of the urging means 4. By this rotation, the lid R at the slide end position is rotated to the rotation end position. Since the lid R can be slid forward from the closed position and then rotated to open the opening Ha closed by the lid R, the lid R and the opening are opened when the lid R is opened. Interference with the front surface Hb of the main body H provided with Ha can be made difficult to occur, and special consideration is given to such interference when selecting the shape of the front surface Hb of the main body H provided with the opening Ha and the shape of the lid R. No need to pay.

  In this embodiment, since one end of the through groove 208 is the abutting portion 208a, the posture control unit 303 is abutted against the abutting portion 208a by the urging force of the urging means 4. By doing so, the rotation of the rotating body 3 can be stopped, and the lid R can be stably positioned at the rotation end position.

  When the lid R positioned at the rotation end position (position in FIG. 9) is operated so as to be pushed back to the position before rotation, the rotation body 3 is pushed back to the position before rotation (position in FIG. 6). When the lid R is operated to push backward, the attitude control unit 303 enters the linear guide groove 112 again, and the slide body 2 is pushed back to the retracted position (position in FIG. 3). When the slide body 2 is pushed back to the retracted position, the latch device 6 maintains the push-back state of the slide body 2, and the lid R is positioned at the closed position where the opening Ha is closed.

  When the lid R has a corresponding width in the left-right direction, two or more support mechanisms described above are provided at intervals in the left-right direction of the lid R to support the lid R. It is preferable to do so.

  Further, in this embodiment, the support mechanism includes a braking unit 7 that applies braking to the rotation toward the rotation end position of the rotating body 3 by the urging of the urging unit 4. .

  In the illustrated example, a main body case 701 in which a viscous fluid such as silicon oil or grease is sealed at the bottom of the substrate 200 of the slide body 2, and the main body case 701 rotates while receiving the resistance of the viscous fluid. A damper tool 700 comprising a rotor part (not shown) and a rotating body 702 having a gear part 702a that is outside the main body case 701 and meshes with the rack 304 of the rotating body 3 is attached. Functions as the braking means 7.

  Thereby, in this embodiment, the urging means 4 prevents the lid R from rotating vigorously from the slide movement end position toward the rotation end position. It is possible to add a sense of quality to the operation of the lid R.
