Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a pencil case with an inner plate.

(Prior Art) Conventionally, an inner cover plate is pivotally attached to one side of the storage box body, and a spring is mounted on the pivoted portion to act in a direction in which the inner cover stands up. A stationery storage box is known from Japanese Utility Model Publication No. 51-370, which is provided with a stopper between the main body and the inner cover plate to stop the inner cover plate in the closed position against the above-mentioned spring.

(Problem to be solved by the invention) The above known example is convenient because the inner cover plate stands up by the action of a spring, but in order to make the inner cover plate stand up, it is necessary to open the cover. Afterwards, it is necessary to slide the knob and remove the stopper from the inner cover plate.
The inner lid plate does not stand up completely automatically,
The convenience was insufficient. The purpose of the present invention is to provide a pencil case that is much more convenient than the above-mentioned known example, as the inner tray stands up completely automatically by simply opening the lid and no further operations are required. It is something.

(Means for Solving the Problems) In order to achieve the above object, the pencil case of the present invention is provided with a through hole in the side wall on the side where the lid is hinged, and an upwardly facing inside position of the through hole. A container body is provided with a stopper body that has a hook portion and a sideways pushing piece portion, and is biased by a spring body so that the pushing piece portion can slide freely in the direction of penetrating the through hole, and a through hole in the container body. One side wall portion is hinged at an internal position of the other side wall where it intersects with the side wall having the above-mentioned side wall, so that it can be freely raised and lowered by rotation, and when in the prone position, a portion corresponding to the hook portion of the above-mentioned locking body is attached. An engaging piece that engages with the hook part to maintain the prone position is provided, and the inner plate is attached to the hinge part with a spring body that biases it in the rising direction. The outer surface of the side wall on the side that is hinged to the container body, which comes to a position facing the through hole in the container body when the lid is slid open, is in contact with the tip of the pusher piece of the locking body that penetrates through the through hole in the container body. By pressing and moving the locking body toward the inside of the container body, the hook portion of the locking body is removed from the engagement piece of the inner plate, and the inner plate is automatically established by the upper spring body. It consists of a lid body provided with a protrusion.

(Embodiment and operation) The figure shows an embodiment of the present invention, and the operation and operation thereof will be explained below based on the drawing.

1 is a container body made of a metal plate, and 2 is a lid body similarly made of a metal plate, and the lid body 2 is slidably connected to one side wall of the longitudinal side of the container body 1 by a hinge 3. A through hole 5 is opened at the side end of the side wall 4 having the hinge 3 of the container body 1, and a hook portion 6 is provided upwardly in the inside position of the through hole 5 and extends sidewardly. A coil spring in which a locking body 8 with a protruding push piece 7 is fitted into a guide groove 10 of a box 9 provided at a corner of the container body 1, and is interposed between its rear end and the rear end wall of the guide groove 10. 11 so that the pushing piece 7 can freely slide in the direction penetrating the through hole 5. A support plate 13 is erected from the box 9 at an internal position of another side wall 12 that intersects with the side wall 4 having the through hole 5 of the container body 1, and a support plate 14 is installed on the support plate 13. Medium plate 15
is hinged on the outer surface of the side wall, and a torsion spring 16 is attached to the support shaft 14 for biasing the inner plate 15 in a direction to rotate and raise it. This inner plate 15 has a depth that extends to approximately the middle part of the container body 1 in a face down state, and a side wall located along the inner surface of the side wall 4 having the hinge 3 of the container body 1 in the state of being sunk into the container body 1. Engagement piece 1 having a locking hole 17 in the part
8 is provided to protrude downward. This engagement piece 1
The position of the locking hole 17 of 8 corresponds to the position of the hook portion 6 of the locking body 8 when the inner plate 15 is turned down. Therefore, when the inner plate 15 is in the down position, the locking body 8 is pushed by the coil spring 11 and the hook portion 6 is held against the inner plate 1.
Insert the inner plate 1 into the locking hole 17 of the engaging piece 18 of No. 5.
Prevent 5 from getting up. The lid 2 hinged to the container body 1 has the above-mentioned surface on the outer surface of the side wall 19 facing the outer surface of the side wall 4 of the container body 1 when the lid 2 pivots 180 degrees to take the open state. A protrusion 20 is provided at a location corresponding to the position of the through hole 5. This protrusion 20 presses the push piece 7 of the locking body 8 which is pushed out by the coil spring 11 from the through hole 5 of the container body 1 when the lid body 2 pivots 180 degrees and assumes the open state. and slide the locking body 8 backward. The amount of sliding of the locking body 8 at this time is set within a range in which the hook portion 6 is pulled out from the locking hole 17 of the inner plate 15. Therefore, when the lid body 2 is opened 180 degrees, the inner plate 15 is released from the locking state by the locking body 8 and is lifted up by the torsion spring 16. The rising angle of the inner plate 15 at this time is appropriately set by the range in which the torsion spring 16 acts, the stopper, etc.
In addition, on the hinged side wall side of the inner plate 15 and on the container body 1
A recessed part 21 is provided at the bottom of the corner on the side wall 4 side having the hinge 3, in which a quarter gear 22 is installed, and the guide groove 1 of the box 9 of the container body 1 is provided.
A gear 23 is also installed in a space provided on the side of 0, and the two are meshed. The gear 23 on the side of the container body has a slightly heavier rotation, and the inner tray 1
5 acts as a buffer to prevent it from rising suddenly due to the torsion spring 16. When the lid body 2 is closed, the pressure on the push piece 7 of the locking body 8 by the protrusion 20 is released, and the locking body 8 is moved by the coil spring 1.
1, the hook portion 6 moves forward by being pressed by the inner plate 15.
The engagement piece 18 moves forward to a position where it can engage with the locking hole 17 of the engagement piece 18. Therefore, by turning the inner plate 15 upside down with the closing movement of the lid body 2, the engaging piece 18 of the inner plate 15 and the locking body 8
is engaged, and the inner tray 15 maintains its prone position again.

(Effects of the invention) The present invention has the above-mentioned structure and function, and when the lid body is moved 180 degrees to open the lid, the inner tray is released from the latched state, and no further operation is required. The device will completely automatically stand up at the required angle without tilting up, making it extremely convenient to take out writing instruments, etc. from the inner tray or from the container body on the underside of the inner tray, and vice versa.
