Description

[Detailed description of the invention] This invention relates to a type of ladder device that is attached to the exterior wall of a building.The purpose of this invention is to allow workers to climb through the windows of the building when removing snow from the roof or performing repair work. To provide a new window ladder device with an extremely simple structure and at low cost, which has a convenient function of use, allowing extremely safe and easy access to and from the roof.

The present invention has been devised in order to achieve the above-mentioned object, and its structure will now be described in detail with reference to the drawings of embodiments.

That is, the reference numeral 1 in the drawing is a ladder that is attached to the outer wall surface P of the building H, and the ladder 1 consists of two vertical rungs 2, 2 and an appropriate number of rungs connected horizontally between the vertical rungs 2, 2. 3 is the same as a conventional ladder, but in the case of the present invention, the ladder 1
The lower end portion of the vertical beam 2.2 is bent in an arc shape toward the outer wall surface P of the building H, and the tip of the bent portion 1a is placed below the lower frame W1 of the window W to the outer wall surface P of the building H. The upper end 1b of the ladder 1 has the upper ends of the vertical bars 2, 2 projecting to a higher position than the eaves of the roof, and the intermediate part 1c of the ladder 1 is connected to the building H by an appropriate number of support rods 4. A space S is formed between the ladder 1 and the outer wall P of the building H, where a worker can enter and exit through the window W and go up and down. .

In addition, FIGS. 3 to 5 illustrate the structure of the connecting part between each member constituting the ladder and the building.
The lower end of 2 is connected and fixed to the horizontal member 7 on the outer wall P of the building H with U-bolts 8 as shown in FIG. The ends of the vertical beam 2 and the support rod 4 of No. 1 are fixed by tightening them with bolts 10 in a cross-shaped manner as shown in FIG. Similarly to the lower end of the vertical beam 2, the base of the frame 4 is connected and fixed to the horizontal member 7 of the outer wall P of the building H via the flange plate 11 and soft rubber 12 with U-bolts 13, as shown in FIG. However, the connecting parts of these members are not necessarily limited to the above-mentioned structure, but may also be connected by other connection methods, and may also be connected to members constituting a ladder or horizontal bridges on the external wall of a building. The member may be provided with reinforcing metal fittings 14, 15, 16, a cap 17, etc. as shown in the drawings, if necessary.

Since the ladder device of the present invention has the above structure, when performing snow removal or repair work on the roof, the worker can open the window, put his foot on the step of the ladder, and go up and down while grasping the vertical rung with both hands. Ba,
You can easily go in and out of the window and climb up and down the roof smoothly, so if you install this ladder device somewhere in the building, you can easily go in and out of the window and climb up and down the roof from the ground floor on the first floor. It is very convenient because there is no need to equip a large-scale fixed ladder to reach the top.

In addition, the ladder device of the present invention has the lower end of the vertical bar bent in an arc shape and is fixed below the window, so it can support a large load by distributing the weight from above to the outer wall of the building. Of course, unlike conventional fixed ladders, workers ascend and descend inside the ladder (on the building wall side), so even if a worker misses a step on the ladder, there is no danger of falling directly to the ground. It has excellent advantages such as high safety and does not give workers the fear of falling, and combined with the fact that the overall structure of the device is simple and the manufacturing and installation costs are low, it is an outstanding product. It is effective.
