Description

[Detailed description of the invention] The present invention relates to a locking mechanism for an opening/closing member. To explain in more detail, one end is detachably connected to the fixed part, and the other end is pivoted by a support shaft and attached to the fixed part. The present invention relates to a locking mechanism for an opening/closing member that is provided so as to be openable and closable.

Conventionally, accessory cases etc. have a fixed part side with a storage part,
An opening/closing member for opening and closing the storage section on the fixed part side is provided, and one end of this opening/closing member is attached to the fixed part side via a detachable locking mechanism. In addition, there are console boxes, center armrests, etc. that are installed in the passenger compartment of the vehicle, and when opening and closing these accessory compartments, quick operation, reliable locking, and safety are required. ing. In addition, there are few accessory cases for storing atlases, cassette tapes, memo pads, and other documents in vehicles, and when these various items are placed on the seats, there is a risk of deteriorating the appearance.

The purpose of the present invention is to provide a locking mechanism for an opening/closing member that can quickly and reliably open and close the opening/closing member and has excellent safety since the locking mechanism is not exposed to the outside. It will become clear from the detailed explanation.

1 and 2 show a locking mechanism for an opening/closing member according to the present invention on a seat back 3 of a vehicle seat 1.
In this example, the seat bag 3 is formed as a fixed part, and a part of the center of the front side of the seat bag 3 is formed as a tilting member 5 as an opening/closing member. The tilting member 5 is configured to be able to be pulled out forward from the seat back 3, and a storage portion 6 for storing various articles is formed on the back side of the tilting member 5. Note that numeral 2 indicates a seat cushion.

That is, a recess 4 that opens downward is formed in the center of the seat bag 3, and the inside of the tilting member 5 formed to fit into the recess 4 is formed into a hollow shape, so that various functions can be carried out. A storage section 6 for storing articles is provided. Note that in this embodiment, the storage section 6 is configured by the groove formed inside the tilting member 5 and the back plate 3a of the seat back 3, but the present invention is not limited to this. Of course, the tilting member 5 may be provided with a lid that covers the upper part of the storage section 6, for example.

The above-mentioned tilting member 5 is centered around the support shaft portion 8 at the lower end of the tilting member 5, and the recessed portion 4 of the seat back 3 is
It is constructed so that it can be opened and closed within the interior, and can be changed between the normal state shown in FIG. 1 and the use state shown in FIG. 2. In addition,
Reference numeral 7 in the figure is a tension member for pulling out the tilting member 5.

Here, the above-mentioned tilting member 5 is configured to be detachable from the seat bag 3 by a locking mechanism 10 for an opening/closing member according to the present invention shown in FIGS. To explain this in detail, in the figure, 11 is a fixed frame on the side of the seat bag 3, and 12 is a movable frame with a substantially U-shape provided on the side of the tilting member 5. It is provided in the member 5. A part of the back plate of the movable frame 12 is cut out and opened, and a hook 14 facing into the movable frame 12 through the opening 13 is rotatably attached to the fixed frame 11 by a pin 14d. The hook 14 is supported and urged counterclockwise in FIG. 3 by a spring 15. Also, this hook 1
4, the tips thereof are the first and second tapered surfaces 14
a and 14b are formed into a substantially triangular shape, and the second tapered surface 14b extends in the rotational direction of the hook 14 and is formed by a third tapered surface 14c facing toward the base thereof, thereby forming a locking pawl. 16 are provided.

On the other hand, on the movable frame 12 side, a pair of locking pins 17 and 18 are supported at appropriate intervals in the front-rear direction, which is the insertion direction of the hook 14, between the bottom plates. Stop pin 1
The locking pawl 16 of the hook 14 is configured to be locked between 7 and 18. The movable frame 12 has a substantially L-shape, one end of which is rotatably supported by a pivot pin 23, and the other end of which is extended forward of the movable frame 12 to form the tension member. Lock lever 1 with 7 fixed
9 is disposed, and this lock lever 19 is biased counterclockwise in FIG. 3 by a spring 20 about a pivot pin 23. The lock lever 19 has a pair of locking pins 17 and 18 at its base.
A lock pin 21 is fixedly installed to pinch the hook 14 locked between the two from the opposite side, and this lock pin 21
is an arcuate guide groove 22 bored in the movable frame 12.
It is configured to be able to move within a and 22b. In the above embodiment, the pair of locking pins 1
7 and 18 are shown, of which the locking pin 18 has the function of preventing the movable frame 12 from moving too far relative to the fixed frame 11, and the width of the movable frame 12 in the movable direction is thick. This is effective in some cases, and is unnecessary if there is no risk of the movable frame 12 going too far.

The lock mechanism 10 having such a configuration operates as follows.

First, in the normal state shown in FIG. 1, the lock mechanism 10 is in the state shown in FIG.
The locking pawl 16 is locked by the locking pins 17 and 18, and the locking state is maintained by being pressed by the locking pin 21 from the opposite side. It is inserted and held inside.

In this state, when the tension member 7 is pulled forward of the seat, the state shifts from FIG. 4 to the state shown in FIG. Since the locking pin 21 is removed, the hook 14 rotates clockwise in the figure due to the engagement between the third tapered surface 14c and the locking pin 17 to release the locked state, and as a result, the tilting member 5 is rotated toward the front of the seat as shown in FIG.

Further, when closing the tilting member 5, it is sufficient to press the tilting member 5 so as to fit it into the concave portion 4 of the seat bag 3. That is, the movable frame 12 approaches the fixed frame 11, and the second tapered surface 14b of the hook 14a touches the locking pin 1.
7, the hook 14 is rotated clockwise, and at this time, the first tapered surface 14a engages with the lock pin 21 and acts to rotate the lock lever 19 forward of the seat. When the second tapered surface 14b receives the locking pin 17 and is engaged between the locking pins 17 and 18, the lock lever 1
9 returns to its original state and locks the hook 14 with the lock pin 21.

According to the locking mechanism of the opening/closing member according to the present invention,
To open the storage section of the tilting member, you only need to pull the tension member toward the front of the seat, and to close it, you only need to press the tilting member toward the rear of the seat.
The attachment/detachment operation is simple and can be performed with one touch, and moreover, a reliable locking state can be obtained.

In the above embodiment, the tilting member 5 at the center of the seat bag 3 is used as the opening/closing member, and the seat bag 3 is used as the fixed part, but the locking mechanism of the present invention is applicable to console boxes, center armrests, etc. It will be obvious that the present invention can be similarly applied to opening/closing members, and various other changes can be made without departing from the spirit of the present invention.
