Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a structure for mounting a ladder in a semi-underground storage shed whose lower part is buried underground.

[Background Art] Conventionally, a ladder is installed in a semi-underground storage shed whose lower part is buried underground, and the ladder is used to access the inside of the semi-underground storage shed through an opening in the floor of the building. was. By the way, the ladder installed inside this semi-underground storage is fixedly attached to the semi-underground storage, so when putting things in and out of the shelf at the back of the ladder inside the semi-underground storage, it is fixedly attached. Because there was a ladder, the ladder got in the way and it was inconvenient to put things in and take them out.

[Purpose of the invention] The present invention was devised in view of the above points, and its purpose is to make it possible to remove a ladder installed in a semi-underground storage with a simple structure, and to remove the ladder from the back of the ladder. A ladder mounting structure for a semi-underground storage shed that allows items to be taken in and out of shelves without being obstructed by the ladder, and the mounting brackets that support the ladder are simple and strong, and can reliably support the ladder. is to provide.

[Disclosure of the invention] The structure of the semi-underground storage with shelves of the present invention is such that two mounting fittings 3 are attached to one side edge of the opening 2 at the top of the semi-underground storage 1, and the metal fittings 3 are attached to the inside of the opening 2. The protruding portion 4 of the mounting bracket 3 that protrudes from above is formed into an inverted L shape consisting of a vertical piece 5 and a horizontal piece 6 extending from the upper part of the vertical piece 5, and the vertical pieces 5 of the adjacent mounting brackets 3 are made to face each other. At the same time, the extending direction of the horizontal piece 6 is made to continue in the direction away from the adjacent mounting bracket 3, and a vertical cut 7 and a horizontal cut are made in the vertical piece 5 and the horizontal piece 6 from the corner of the vertical piece 5 and the horizontal piece 6, respectively. A pin 10 is provided on both sides of the upper part of the ladder 9 to be placed inside the semi-underground storage shed 1, respectively, so that the vertical cut 7 and the horizontal cut 8 communicate with each other at the corner.
The protruding length of the pin 10 is made shorter than the horizontal cut 8, and the pin 10 is inserted into the vertical cut 7 from the horizontal cut 8, and is supported at the lower end of the vertical cut 7, and the lower end of the ladder 9 is cut in half. It is constructed by being grounded at the bottom of the underground storage 1, and by adopting such a configuration, the above-mentioned object of the present invention is achieved.

The present invention will be explained in detail below with reference to Examples. In the figure, reference numeral 1 is a semi-underground storage shed, the lower part of which is buried in the ground 11, and the upper opening 2 opening at the floor 13 of the building 12. This semi-underground storage 1
Two fittings 3 are attached to one side edge of the opening 2 at regular intervals. Mounting bracket 3
The protrusion 4 that protrudes into the opening 2 of the vertical piece 5
and a horizontal piece 6 extending from the upper end of the vertical piece 5, forming an inverted L-shape. Here, the vertical pieces 5 of the adjacent fittings 3 are made to face each other, and the horizontal pieces 6 are extended in a direction away from the neighboring fittings 3. Vertical piece 5 of mounting bracket 3
A vertical cut 7 and a horizontal cut 8 are provided in the vertical piece 5 and the horizontal piece 6 from the corner of the vertical piece 5 and the horizontal piece 6, respectively, and the vertical cut 7 and the horizontal cut 8 are made to communicate with each other at the corner. In the figure, 9 is a ladder, and pins 10 protrude outward from both ends of the upper part of the ladder 9, respectively. The protruding length of this pin 10 is shorter than the cut length of the above-mentioned transverse cut 8. Then, the pins 10 at both ends of the upper part of the ladder 9 are inserted into the vertical notches 7 through the horizontal notches 8, and the pins 10 are locked to the bottom of the vertical notches 7, and in this state, the lower part of the ladder 9 is stored semi-underground. Warehouse 1
It is grounded at the bottom of the When going in and out of the semi-underground storage 1, the person goes in and out through an opening 2 that opens into the floor 13 of the building 12 along a ladder 9. On the other hand, if the ladder 9 gets in the way when putting things in or out of the shelf 14 at the back of the ladder 9 in the semi-underground storage 1, lift the ladder 9 upwards and release the pin 10 as shown in FIG. The ladder 9 is removed from the fitting 3 by pulling it out upward from the vertical cut 7 through the horizontal cut 8. By the way, the mounting bracket 3 shown in FIG. 6 is also conceivable, but the comparative example shown in FIG. Therefore, the tip 5a of the vertical piece 5 has a free end and its strength is weak, but the mounting bracket 3 of the present invention has a horizontal piece 6 extending from the upper end of the vertical piece 5, and a vertical cut 7 and a horizontal piece. Notch 8
Since the top of the vertical piece 5 is reinforced by the horizontal piece 6, the strength of the part of the mounting fitting 3 that supports the ladder 9 is increased.

[Effect of the invention] In the present invention, as described above, two mounting brackets are attached to one side edge of the opening at the top of the semi-underground storage, and two mounting brackets are attached to both sides of the upper part of the ladder that enters the semi-underground storage. Protrude the pins toward the outside of each, insert the pins into the vertical notches from the horizontal notches of the protruding parts of the mounting bracket, and support them at the lower ends of the vertical notches, while also grounding the lower end of the ladder to the bottom of the semi-underground storage. This allows you to easily remove the ladder from the mounting bracket by lifting the ladder upwards, and as a result, you can easily remove the ladder from the mounting bracket by lifting the ladder upwards. This allows you to put things in and take them out without getting in the way. Moreover, the protruding part of the mounting bracket that protrudes toward the inside of the opening is formed into an inverted L shape consisting of a vertical piece and a horizontal piece extending from the top of the vertical piece, and the vertical pieces of the adjacent mounting brackets are arranged to face each other. At the same time, the extending direction of the horizontal piece is made to extend in the direction away from the adjacent mounting bracket,
A vertical cut and a horizontal cut are provided at the corners of the vertical and horizontal pieces, respectively, and the vertical and horizontal cuts are communicated at the corner, so a simple mounting bracket can be used. A ladder can be detachably supported. Furthermore, since the protruding length of the pin is shorter than that of the transverse cut, the pin can be easily inserted and removed from the transverse cut even though a horizontal piece is provided.
