Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shelf / lid opening / closing mechanism in which a shelf and / or a lid is opened / closed with one touch and opened / closed.

[0002]

2. Description of the Related Art Conventionally, the following documents are cited as prior arts for opening and closing a lid (lid). (1) There is a lid opening / closing device of Japanese Utility Model Publication No. 57-11874. The gist thereof is composed of a shaft portion that is movably provided in a pair of groove portions provided in a cabinet, and a lid body that is supported by the shaft portion and that is opened and closed according to the curved shape of the groove portion. The lid is configured to be opened / closed or opened / closed (corresponding to a state in which the lid is stopped at the open position) corresponding to the groove. (2) Stay mechanism of No. 2-45954, No. 3-75155 door stay device, No. 3-75
There are documents such as a stay device for a door of No. 156. These devices are guide long holes (guide holes) equipped with a stopper mechanism.
And the cover (door) is opened / closed or opened / stopped via a stee (stea arm) engaged in the guide elongated hole.

[0003]

In the prior art described in detail above, since the stee, the locking piece, and the like are guided, and the guide elongated hole that controls the opening and stopping directly moves, The mechanism is large and complicated, it requires force and time (second or minute unit) to open and close the lid, and it is considered that one-touch operation is difficult, or time and manpower are required to store the goods. In short, problems such as inefficiency can be considered.

As a general rule, since a pair of right and left is required to be installed, the structure becomes complicated, and when opening and closing, the left and right tees and the guide holes are operated in alignment with each other. Is required, and it is troublesome and difficult, and it is difficult to perform a simple operation with one hand. In particular, articles with large width and thin thickness, such as plastic parts and steel plate parts, such as spoilers for automobile parts, bumpers, glass plates, bonnets, doors, etc. Therefore, various improvements are required in terms of structure or operation.

[0005]

In view of the above, the present invention provides
The large articles, parts, etc. can be reliably and easily stored in a multi-tiered shelf by one-touch operation, stays at both ends of the shelf, guide rods and other obstacles are not damaged, and large articles, parts, etc. are not scratched, and The following configuration is adopted for the purpose of being able to store it with peace of mind or to store it from the side of the shelf.

That is, the shelf / lid opening / closing mechanism of the storage box according to the present invention includes a storage box capable of storing a large number of articles, a shelf and / or a lid pivotally attached to the storage box so as to be openable and closable, and the shelf and the lid. / Or at least one actuating rod provided on the lid, and a cam groove into which a locking piece of the actuating rod is engaged and which is a circular movement locus for controlling opening / closing and opening / closing of the shelf and / or the lid, The guide means is provided in the cam groove and ensures the forward directionality of the locking piece.

[0007]

The operation of the present invention (opening and closing of shelves and lids, accommodation of articles) will be described below. First, in the case of opening the lid (of course, in the case of a configuration in which the opening / closing mechanism is provided in the lid. Therefore, if the mechanism is not provided, then simply opening and stopping the lid, etc.) Free end side (not limited; the same applies below)
When the lid is gripped and the lid is lifted (opened), the lid is sequentially opened with the pivotal portion as a fulcrum, and at the same time, the operating rod is pulled up, and thus the bottom dead center of the first cam groove is reached. Therefore, the locking piece moves sequentially on the climbing track.

[0008] On the other hand, when the top dead center is reached, the lid is opened to the maximum with the pivotal portion as a fulcrum. After that, when the fully opened lid is lowered slightly, the locking piece descends and descends on the horizontal orbit with the help of the receiving piece, and reaches the intermediate top dead center. When the intermediate top dead center is reached, the lid is opened, and the lid is opened and the opened state is maintained, that is, the opening of the lid is stopped through the mooring of the intermediate top dead center and the locking piece. Can be achieved.

When the lid is stopped to be opened as described above, subsequently, for example, the upper shelf is opened. Also in this case, the same operation and procedure as in the case of the lid are performed. Specifically, when the free end side of the upper shelf is grasped and the upper shelf is lifted, the upper shelf is sequentially opened around the pivotal joint as a fulcrum, and at the same time, the operating rod is pulled up. Therefore, the locking piece located at the bottom dead center of the second cam groove sequentially moves on the climbing track. Then, on the other hand, when reaching the top dead center, the upper shelf is opened to the maximum with the pivot portion as the fulcrum. After that, when the upper shelf that is opened to the maximum is lowered a little, the locking piece descends and descends on the horizontal track with the help of the receiving piece, and reaches the middle top dead center. When the intermediate top dead center is reached, the upper shelf is opened, and the upper shelf is opened and the open state is maintained, that is, by holding the locking piece at the intermediate top dead center. The opening of the upper shelf can be stopped.

As described above, when the upper shelves are opened and stopped, and when the lower shelves are present (therefore, when there is no shelves, this is an unnecessary work and operation). Since the opening and stopping are the same as the operation and procedure of the upper shelf, and the relationship and operation between the third cam groove and the locking piece are also the same, the description thereof will be omitted.

When the lids and the upper and lower shelves are opened and stopped as described above, the articles are stored. Specifically, first, the articles are sequentially accommodated on the article platform provided on the inner bottom surface. Of course, it is limited to a storage box that can be stored on the inner bottom surface.

In this way, when the articles are accommodated on the inner bottom surface, and when the articles are then accommodated on the article table of the lower shelf, the free end side of the lower shelf which has been stopped is grasped. Then, when the free end side is slightly lifted, the operating rod is simultaneously lifted, and the locking piece at the middle top dead center of the third cam groove moves on the other horizontal orbit sequentially. . On the other hand, at the stage of reaching the top dead center, the lower shelf is opened to the maximum as much as the above with the pivot portion as the fulcrum, but at this time, the locking piece is already guided to the notch portion and descends. Since it has reached the orbit, it descends and descends smoothly and quickly from the descending and descending track, and the lower shelf that has been opened to the maximum gradually swings toward the closing direction (returns to the initial closed state). .), When the locking piece reaches the bottom dead center, the lower shelf is closed. Therefore, the articles are sequentially accommodated on the article table provided on the lower shelf.

As described above, when articles are stored in the lower shelves and there are upper shelves, the articles are also stored in the upper shelves. At this time, first, when the free end side of the upper shelf which is stopped to be opened is grasped and the free end side is slightly raised, at the same time, the operating rod is pulled up, so that the upper middle portion of the second cam groove is raised. The locking piece at the dead point moves on the other horizontal orbit one after another. On the other hand, at the stage of reaching the top dead center, the upper shelf is opened to the maximum as much as the above with the pivot portion as the fulcrum, but at this time, the locking piece is already guided to the notch portion and descends. Since it has reached the orbit, it smoothly descends and descends from the descending orbit, and the uppermost shelf that has been opened to the maximum gradually swings in the closing direction (returns to the initial closed state). When the locking piece reaches the bottom dead center, the upper shelf is closed. Therefore, the articles are sequentially stored in the article mounting table provided on the upper shelf.

As described above, when the articles are stored in the article mounting table provided on the upper shelf, the lid which is opened and closed is closed (of course, it is not necessary if the lid is not provided. ). The operations and procedures from opening and closing of the lid to closing of the lid, the movement of the locking piece in the first cam groove, and the like are the same as those of the above-described upper and lower shelves, and therefore description thereof is omitted.

Through the operations, procedures, and operations (processes) detailed above, articles are stored in or taken out from the inner bottom surface and / or upper and lower shelves. The article is taken out by opening and stopping the lid and / or the upper and lower shelves, but the description thereof will be omitted because it can be understood by referring to the above description.

And a locking piece 66 provided at the lower portion of the operating rod 65 is inserted into the cam groove A. The cam groove A (referred to as a second cam groove) is provided in the pillar 67 that is erected from the inner bottom surface 111 of the housing box 1.

The structure of the cam groove A will now be described with reference to FIG. 4. The cam groove A is inserted into the substantially heart-shaped cam hole 81, the receiving piece 91, the valley 92, the notch 93 and the stop piece 94. When the cam 9 is inserted into the cam hole 81 of the cam plate 8 through the mounting rod 68, the substantially heart-shaped cam groove A is formed. It is formed. When the locking piece 66 is located at the bottom dead center A1 of the cam groove A, the upper shelf 6 is closed and in a so-called horizontal state. Then, the locking piece 66 climbs up the climbing track A2 of the cam groove A, whereby the upper shelf 6 is sequentially opened (swinged). Then, on the other hand, when reaching the top dead center A3, the upper shelf 6 is maximally opened. At that time, since the cam 9 is provided with the receiving piece 91, the locking piece 66 located at the top dead center A3 on the one hand.
Is reliably and smoothly guided to the intermediate top dead center A5 via the horizontal orbit A, the locking piece 66 is temporarily fixed, and the upper shelf 6 is in an open / stopped state. After that, in order to close the upper shelf 6 and bring it into a horizontal state, the locking piece 66 at the intermediate top dead center A5 is moved to reach the descending track A8 via the top dead center A7 and the notch 93, and When it reaches the bottom dead center A1 via the descending track A8, it returns to the initial state and the upper shelf 6 is closed, that is, in a horizontal state.

Next, the relationship between the lower shelf 7 and the cam groove A shown in FIGS. 1 and 2 will be described. The stee 73 that is passed to the pivot side of the lower shelf 7 is extended from the stee 73. The operating rod 75 hangs down through the provided auxiliary stee 74, and the locking piece 76 provided at the lower portion of the operating rod 75 is inserted into the cam groove A. The cam groove A (referred to as a third cam groove) is a column member 77 that is erected from the inner bottom surface 111 of the housing box 1.
It is provided in.

The structure of the cam groove A will now be described with reference to FIG. 4. The cam groove A is inserted into the substantially heart-shaped cam hole 81, the receiving piece 91, the valley 92, the notch 93 and the stop piece 94. When the cam 9 is inserted into the cam hole 81 of the cam plate 8 via the mounting rod 78, the substantially heart-shaped cam groove A is formed. It is formed. Then, the locking piece 76 is placed at the bottom dead center A1 of the cam groove A.
When there is, the upper shelf 6 is closed and in a so-called horizontal state. Then, the climbing track A2 of the cam groove A is engaged with the locking piece 7
