Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an installation type ladder device on a loft-type mezzanine floor in a one-room apartment or villa.

[0002]

[Prior art]

 On loft-type mezzanine floors in one-room apartments and villas, the conventional climbing ladders are installed with inclined hooks at the upper part and vertical hooks at the lower part with a space inside the upper part of the ladder. When hanging the hook, insert the hook part of the inclined hook fitting into the above-mentioned locking groove to support it in an inclined manner, and when removing it, lift the ladder from that state and fit the hook part of the vertical hook tool into the locking groove and store it Hang in the state.

[0003]

[Problems to be solved by the invention]

 However, in this conventional means, it takes time and effort to lift and move the ladder one by one when hanging up and off. Particularly, in the case of a wooden ladder, the weight of the ladder is 10 kg or more, so that the work burden is large for women and women. Therefore, the present invention provides an installation ladder device that can be easily attached and detached with one touch on the loft-type mezzanine floor.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention forms the lower edges 2a of the both-side vertical rails 2 on which the horizontal rails 3 are erected on the front inclined surface 8 having a predetermined angle α, and attaches the door wheel 9 to the lower end opening 2b of the spring 6. Attach so that it can appear within the allowable range. Then, a guide track 10 provided with an elongated hole 11 with a gap secured between the inner side surface 2c and the upper side surface 2c of the longitudinal rail 2 is fixed. A dowel 13 protruding from the other wing 12b of the hinge fitting 12 having the one wing 12a fixed to the loft floor side F is slidably fitted in the elongated hole 11 of the guide track 10, and is a loft-type mezzanine floor. It is an installation ladder device in.

The overall body 1 is made of a light metal material, and in particular, the vertical rails 2 on both sides on which the horizontal rails 3 are installed are cylindrical, and the lower end edge 2a is formed on the front inclined surface 8 having a predetermined angle α and the lower end opening 2b The door 9 is mounted so as to be able to come and go within the allowable range of the spring 6. A guide track 10 having an elongated hole 11 provided with a gap between the inner side surface 2c and the inner side surface 2c is fixed to the upper side surface 2c of the vertical rails 2 on both sides. Then, a dowel 13 projecting from the other wing 12b of the hinge fitting 12 having the one wing 12a fixed to the loft floor edge side F is slidably fitted into the elongated hole 11 of the guide track 10 so as to be slidable. It is an installation ladder device in.

Further, in the above-described configuration, the door wheel 9 is fitted via the spring 6 to the spring pedestal frame 4 which is fitted to the cylindrical lower end portion 2 b of the vertical rail 2 on both sides and has the front inclined surface 5 formed on the bottom edge. It is a loft-type mezzanine floor installed ladder device.

[0007]

[Action and effect of the invention]

 The present invention is as described above. The ladder is always installed on the loft floor side via the hinge fitting 12, and in use, since the door wheel 9 is in contact with the floor on the first floor when pushing and pulling. Sliding can be carried out smoothly, and the front inclined surfaces 8, 5 at the bottom edges of both vertical rails 2 become horizontal with the floor in the state of being inclined, and the vertical rail 2 moves up and down in the guide track 10 at that time. It is absorbed by the dowel 13 of the hinge fitting 12.

[0010] As a result, unlike the conventional lifting mobile ladder, even women and women can push and pull easily and easily with one touch, and the first floor can always be secured in the maximum space.

[0009]

[Embodiment of the invention]

 In FIG. 1, reference numeral 1 denotes a light metal material as a whole, and in particular, a vertical bar 2 on both sides on which a horizontal bar 3 is erected is formed in a cylindrical shape, and a lower end edge 2a is formed on a front inclined surface 8 having a predetermined angle α and a door wheel 2b is provided at a lower end opening 2b 9 is mounted so as to be able to protrude and retract within the allowable range of the spring 6. More specifically, a door roller 9 is mounted via a spring 6 to a spring pedestal frame 4 which is fitted to the cylindrical lower end portion 2b of each of the vertical rails 2 on both sides and has a front inclined surface 5 at the bottom edge. Then, a guide track 10 provided with an elongated hole 11 with a gap secured between the inner side surface 2c and the upper side surface 2c of the longitudinal rail 2 is fixed. As shown in FIG. 2, a dowel 13 projecting from the other wing 12b of the hinge fitting 12 having the one wing 12a fixed to the loft floor edge F is slidably fitted into the elongated hole 11 of the guide track 10. This is an installation ladder device on the loft-type mezzanine floor.
