Description

[Detailed description of the invention] (Field of industrial application) The present invention provides a locking device for a lid body that covers the armrest of an automobile seat in which a container is embedded inside so that it can be used as an article storage device. Regarding.

(Prior Art) As shown in FIG. 7, the conventional armrest with a container releases the locked state of the lid B' that covers the container A' by operating a lever a provided on the front side of the armrest. Next, the lid is opened by pulling the strap b.

By the way, when an armrest with such a structure is equipped with a control unit (a unit that houses the operating section for adjusting the seat tilt angle, opening/closing the car window, etc.) on the front side of the body, this unit can be used to control the lever. An operating section for opening and closing the lid B' such as a cannot be provided on the front side of the armrest.

Therefore, if a container with a lid is buried behind the control unit, it is necessary to provide an operating section for opening and closing the lid. It is desirable that this operating section be disposed on the top side of the lid so that it can be used by the left and right occupants seated on the seat. There are various types of operation parts that can be used to open and close the lid (for example, one that unlocks the lid by sliding the operating lever, one that unlocks the lid by pulling the strap, etc.) ),
It is preferable to use a push button to release the lock because it does not spoil the appearance of the armrest (sliding type has a long hole for sliding, and strap type has a strap exposed on the surface of the armrest).

If the lid is automatically lifted from the top surface of the container when the lock is released by the push button, the lid can be easily opened. Therefore,
One possible method is to lift the lid upward by springing the lock piece upward by the elasticity of a spring provided on the container side after the lock is released.

However, according to this method, the lock piece is spring-loaded upward before and after the lock, so when the lock piece is operated between the locked state and the unlocked state, the spring spring makes the operation smooth. There was a problem in that it was not possible to do this properly and it was not possible to ensure the locked state.

(Purpose) Therefore, the purpose of the present invention is to improve the operability of the locking piece and to ensure the locked state in an armrest having a structure in which the lid is opened by releasing the locked state of the lid against the container using a push button. It is to do so.

(Structure) The gist of the present invention to achieve the above purpose is to provide a locking hole in which a lock piece on the lid side engages with the container side to which the lid is covered, and a locking hole built in the locking hole. A pusher is provided to press upward, and on the other hand, a lock piece is provided on the lid side that engages with the locking hole and is rotatably pivoted, and a lock piece that is fixed near the lock piece and has a receptacle with respect to the lock piece. An insertion piece is provided that projects a large amount in the lateral direction and is inserted into the locking hole against the pressing force of the presser.

(Function) When locking by inserting the lock piece on the lid side and the insertion piece into the locking hole against the pressing force of the presser on the container side and engaging the lock piece with the locking hole, the Since the length of the insert piece is longer than the lock piece, the push piece in the locking hole is pushed downward by the insert piece, and the push piece does not come into contact with the lock piece. Further, when releasing the locked state, the insertion piece receives the pressing force of the pressing element. Therefore, when locking or releasing the lock, the pressing force of the presser on the container side that lifts the lid upward does not act on the lock piece, so the lock piece operates smoothly and the lock is released. will also be certain.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 6 shows an armrest equipped with a lid locking device according to the present invention, in which B is the lid and the container A is buried behind the control unit C.
The upper surface of the lid B is rotatably attached to the container A at its rear edge, and the structure is such that it can be opened and closed by rotating around this attachment part. A is locked with a lock mechanism provided at the center of the front side of the lid B.

The lid B is composed of an upper plate 3 and a lower plate 2,
The upper plate 3 and the lower plate 2 are fixed together with a predetermined gap, and through holes 31 and 28 are formed in both plates 3 and 2 to pass through this gap in the vertical direction. A locking hole 11 is provided at the hole edge of the container A corresponding to the hole. Insert pieces 22, 22 are provided on both left and right edges of the through hole 28 of the lower plate 2, and the upper sides are bearing parts 22a, 22a, and the lower sides are formed to protrude from the bottom surface of the lower plate 2 toward the container A side. be. A guide tube 29 is provided on the rear edge of the through hole 22 to project upward, and a lock piece 21 is rotatably attached to the bearing portions 22a, 22a by a pin 25.
The lock piece 21 protrudes downward from the through hole 28 and the upper plate 3
Arms 23, 23 extending in the direction of the through hole 31 of the container A are integrally formed, and are urged by a spring 26 wound around the pin 25 so that the lock piece 21 is engaged with the locking hole 11 of the container A. ing.

A square tube 14 with a bottom is integrally formed in the locking hole 11 of the container A, and the locking hole 11 is formed in the square tube 14 by the elasticity of the compression spring 13. A presser 12 is attached that is biased so as to be flush with the flange.

Arms 23, 23 integrated with the above lock piece 21
The L-shaped legs 24b, 24b of the push button 24 are connected by pins 27 to the push button 24, and the push button 24 is mounted so that its head is exposed through the through hole 31 of the upper plate 3. Ganitsushi 3 is on the edge of hole 31.
2 is fixed. 24a in the figure is a push button 24
The guide tube 29 is provided protruding from the leg portions 24b, 24b side.
There are only 12 shafts to be inserted into.

As shown in FIG. 5, the insertion pieces 22, 22, together with the lock piece 21, protrude from the bottom side of the lid B against external force, and the amount of protrusion is larger than that of the lock piece 21.

Therefore, as shown in FIG. 1, when the lid B is pressed downward, the insertion pieces 22, 22 are inserted into the locking hole 11 against the elasticity of the compression spring 13. By inserting the insertion pieces 22, 22, the lock piece 21 is also inserted into the locking hole 11 at the same time, and the lock piece 21 is rotated by the elasticity of the spring 26 which rotates the lock piece 21 in the engagement direction. It engages with the edge of the locking hole 11 and becomes locked.

Further, as shown in FIG. 2, when the push button 24 is pressed downward (in the direction of the arrow), the lock piece 21 rotates around the pin 25, so the lock piece 21 separates from the edge of the locking hole 11 and locks. At the same time as the state is released, the insertion pieces 22, 22 are repelled upward by the pressing force of the presser 12 which is biased by the compression spring 13. Therefore, the lid B is lifted upward from the upper surface of the container A by the amount by which the insertion pieces 22, 22 protrude, so that the lid B can be rotated around its rear end edge and can be opened.

(Effects) According to the present invention, the lock piece and insertion piece inserted into the locking hole of the container are longer than the lock piece in the direction of the container side, so that when the lock is released, The pressing force of the presser on the container side that lifts the lid is regulated by the insertion piece, so that the pressing force of the presser does not directly act on the lock piece.

Therefore, the lock piece operates smoothly and its operability is improved. Moreover, since the locking piece is not affected by the pressing force of the pressing element, locking is performed reliably.
