Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a stay device used to hold the lid of an underfloor storage in a predetermined open position.

[Prior Art] In a conventional stay device, after the lid is opened, the lower end locking portion of the stay main body rotated along the side surface of the lid is manually engaged with the receiver on the upper frame plate of the storage main body. This holds the lid open.

[Problem to be solved by the invention] Since such a manually operated stay device is inconvenient to operate and handle, the stay body automatically engages with the receiver when the lid is opened in conjunction with the opening operation of the lid. Mechanism stay devices have also been proposed, but their structure is relatively complex, and it is necessary to secure a relatively high storage space between the top frame plate of the cabinet body and the lid, and the manufacturing cost is high. It is bulky.

Therefore, the purpose of the present invention is that the stay body is automatically locked and locked when the lid is opened, making it easy to operate and handling, and because it has a relatively thin structure, it can be easily connected to the top frame plate of the cabinet body. To provide a stay device for an underfloor storage that can reduce the height of a storage space between lids and reduce manufacturing costs.

[Means for Solving the Problems] The stay device for an underfloor storage according to the present invention will be described below using reference numerals in the attached drawings. The stay main body 4 is pivotally mounted, the base plate 7 is fixed to the upper frame plate part 5 of the underfloor storage 1 and has a slot 6 for insertion of the stay main body 4, and the base plate 7 is slidably attached to the base plate 7. , and a push plate 9 which is biased to slide in the direction of the stay body 4 by a spring 8, and a locking notch 11 that can be releasably engaged with the locking edge 10 of the slot 6 is attached to the stay body. It is provided on the side surface of the lower end of 4.

[Function] As shown in FIG. 2, when the lid 2 is closed and the lower end surface of the lid 2 is in contact with and supported by the upper frame plate portion 5 of the underfloor storage 1, most of the stay body 4 is attached to the base. Slot hole 6 in plate 7 and escape hole 1 in upper frame plate portion 5
2 and projects below the floor 13 through an opening 14 in the support step. In this lid closed state, as shown in FIG. 3, the side end surface 15 of the stay body 4 is
The contacting state is maintained by the biasing force of the spring 8 acting via the push plate 9.

When the lid 2 is rotated around a hinge shaft (not shown) and opened, the stay main body 4 moves upward within the through hole 12 and the slot 6 while appropriately rotating around the horizontal pivot 3, and the stay main body 4 The side end surface 15 of the slot 6 is in sliding contact with the edge 10 of the slot 6. When the lid 2 reaches the predetermined open position, the stay body 4 is opened as shown in FIG.
The locking edge 10 of the slot 6 is pressed by the spring 8.
The locking notch 11 at the lower end rotates slightly toward the
engages with the locking edge 10 of the slot 6. When the lower edge 16 of the notch 11 comes into contact with the lower surface of the locking edge 10, the rotation of the lid 2 is stopped.

When the lid 2 is released, the lid 2 slightly returns to the closing direction and rotates, and the upper edge 17 of the locking notch 11 comes into contact with the upper surface of the locking edge 10, causing the lid 2 to rotate. is stopped. The engagement state between the locking notch 11 and the locking edge 10 is maintained by the biasing force of the spring 8 acting through the push plate 9, and the lid 2 is locked in the open position.

When closing the lid 2, push the stay main body 4 against the bias of the spring 8 toward the stop portion 18 of the slot 6 on the opposite side from the locking edge 10, and close the locking notch. 11 and the locking edge 10 may be disengaged from each other. This disengagement allows the lid 2 to rotate downward and be closed by its own weight or by manual operation.

Following the closing operation of the lid 2, the stay main body 4 rotates as appropriate around the horizontal axis 3, and connects the underfloor storage 1 through the slot 6 of the base plate 7 and the escape hole 12 of the upper frame plate 5. Projects downward along the sides.

[Embodiment] In the illustrated embodiment, the stay main body 4 is composed of a band plate curved in an arc, and the horizontal pivot 3 is inserted into a receiving hole 19 at the upper end and fixed thereto. Lower surface 2 of lid 2
A bearing plate 23 is fixed to the bearing plate 0 by a mounting screw 22 passing through a mounting hole 21, and both ends of the horizontal pivot 3 are rotatably fitted into a central semi-cylindrical portion 24 of the bearing plate 23.

A long guiding hole 25 is provided in the base plate 7 at a distance from the insertion slot 6 of the stay body 4. A spring receiving plate portion 26 is bent at the base end of the push plate 9 superimposed on the base plate 7 so as to advance and retreat along the slot 6, and the spring receiving plate portion 26 has a guiding length. It is slidably fitted into the hole 25.

Cover plate 27 bent into a U-shaped cross section
The left and right side plate parts 28 and 29 and the spring receiving plate part 30 at the base end are in contact with the upper surface of the base plate 7 so as to surround the elongated guide hole 25, and the positioning plate is provided protruding from the spring receiving plate part 30. The plate portion 31 is tightly fitted to the end of the guide slot 25, and the cover plate 27 is closely fitted to the end of the guide slot 25.
It is fixed to the base plate 7 by a connecting screw 35 that is screwed from a connecting hole 32 into a screw hole 34 at the tip.

The connecting screw 35 connects the base plate 7 and the cover plate 27.
It is inserted into the guide slot 33 of the push plate 9 that slides between the two, and also serves as a guide member for the push plate 9. The biasing spring 8 made of a compression coil spring is attached to the spring receiving plate portion 30 and the positioning plate portion 3 of the cover plate 27.
1 and a spring receiving plate portion 26 at the base end of the push plate 9. The base plate 7 is fixed to the upper frame plate portion 5 by fixing screws 37 inserted through attachment holes 36.

By further rotating the lid 2 in the opening direction with the stay body 4 in contact with the stop edge 18 of the slot 6, the stay body 4
can be pulled out above the base plate 7, and the lid 2 can be placed in a fully open state where it is not supported by the stay body 4. The lower end of the stay main body 4 is formed into an arcuate surface 38 to facilitate reinsertion into the slot 6 of the base plate 7.

[Advantages of the Invention] As described above, the stay device for an underfloor storage bin of the present invention comprises a base plate 7 fixed to the upper frame plate 5 of the underfloor storage bin 1, a stay body 4 pivotally attached at its upper end to the lid 2 by a horizontal pivot 3, which is inserted into a slot 6 in the base plate 7, and a push plate 9 attached to the base plate 7 by a spring 8 which slides and biases it in the direction of the stay body 4.
A locking notch 11 that engages with and disengages from the locking edge 10 of the groove 6 is provided on the side surface of the lower end of the stay body 4, and the structure is greatly simplified, making it possible to reduce manufacturing costs.

In addition, since the stay main body 4 protrudes below the floor 13 through the slot 6 of the base plate 7 and the entire device is configured to be relatively thin, the gap between the upper frame plate portion 5 of the underfloor storage 1 and the lid 2 is increased. The height of the storage space is low,
It can be applied to a lid 2 having a relatively thin structure without any problem.

Furthermore, in the present invention, since the stay main body 4 is rotationally biased by the spring 8 via the push plate 9, simply by opening the lid 2, the locking notch 11 at the lower end of the stay main body 4 is attached to the base. The lid 2 is automatically engaged with the locking edge 10 of the plate 7 to accurately lock the lid 2 in a predetermined open position, and is also easy to operate and handle.
