Abstract

Staircase for niches, characterized by being formed by a quadrangular base formed by four tubes of square profile on which they rise vertically, starting from a point near the ends of one of the tubes, two vertical uprights constituted by profile tubes square, and because on the opposite side of the base split two other oblique uprights also constituted by tubes of square profile that support, regularly distributed, a plurality of steps constituted by rectangular laminar surfaces, and because on the last step appears a platform of plant sensibly square, constituted by a laminar surface, joined to the vertical and oblique uprights, and because on the platform there is a protection enclosure consisting of four vertical tubes and three horizontal ones, with a chain with a hook on the front, and because of the oblique uprights leave vertical tubes that, after suffering a cur are connected to the elements of the upper enclosure, and because at the ends of one of the lateral sides of the base, on the lower part, there are two prismatic appendices, from which emerge horizontal axes on which there are installed cylindrical bodies constituting guide wheels and because in the center of the other side of the base appears another axis with a slightly larger diameter wheel and that has a pneumatic element in its tread, and because the staircase is completed with a guide constituted by a partially closed "U" profile.

Description

Staircase for niches.

Object of the invention

This specification refers to a request for Utility Model that, as expressed in the statement, is refers to a staircase for niches whose purpose is in allow access to the upper row of niches for your care of a safe way as well as being able to move it comfortably to the necessary point.

Field of the Invention

This invention has its application within the industry of metal.

Background of the invention

The applicant knows the existence of various types of stairs. However, he is not aware of the existence of none that presents the characteristics of the one described in the present memory, as it provides security to access the high rows of niches, and allows you to easily move it to the necessary point. Likewise, being a fixed element, it is found always available in the place where it should be used.

Description of the invention

The staircase for niches that the invention proposes, is configured in itself as an obvious novelty within its field of application, allowing access to high rows of niches of in a safe way, as well as moving the ladder to the desired point without much effort thanks to the wheels and guide on which slips. Similarly, the fixed element condition of the guide, prevents the ladder from being moved to other places or use it for other purposes, ensuring its availability in any moment.

More specifically, the staircase for niches is constituted by a quadrangular base formed by four profile tubes square, on which they rise vertically, starting from a point near the ends of one of the tubes, two uprights verticals consisting of square profile tubes. On the side opposite the base split two other oblique uprights constituted also by square profile tubes, which support, regularly distributed, a plurality of steps constituted by rectangular laminar surfaces. On the last step a substantially square plan platform appears, constituted by a laminar surface of identical characteristics to the steps, joined to the vertical and oblique uprights. On platform appears a protective enclosure consisting of four vertical and three horizontal tubes that close the faces Side and back. On the front side there are arranged a chain with hook.

Vertical pipes come out of the oblique uprights that, after suffering a curved join the elements of the upper enclosure, constituting a railing.

At the ends of one of the side sides of the base, for its bottom, there are two prismatic appendages, of the that emerge horizontal axes on which bodies rotate cylindrical components of guide wheels. In the center of the other side of the base another axis appears on which a wheel of somewhat larger diameter and that has a pneumatic element in its tread

The staircase is completed with a guide consisting of a profile in "U" partially closed that is fixed horizontally to the building, and on which the guide wheels slide.

Description of the drawings

To complement the description that is being made and with in order to help a better understanding of the characteristics of The invention is accompanied by the present specification, as integral part of it, 2 sheets of plans, in which, with illustrative and non-limiting nature, what has been represented next:

Figure number 1.- Shows a perspective view of the stairs.

Figure number 2.-. Show a profile view of the stairs.

Figure number 3.-. Show a perspective detail of the guide wheel.

Figure number 4.- Shows a front detail of the guide wheel.

Preferred Embodiment of the Invention

In view of these figures can be seen as the staircase for niches it is constituted by a quadrangular base formed by four square profile tubes (1) on which they are arranged vertically, starting from a point near the ends of one of the tubes, two vertical uprights (2) constituted by tubes square profile. On the opposite side of the base two others start oblique uprights (3) also consisting of profile tubes square, which support, regularly distributed, a plurality of steps (4) constituted by laminar surfaces rectangular On the last step there is a platform (5) of substantially square plan, consisting of a laminar surface with identical characteristics to the steps, supported by vertical and oblique uprights. On platform a protective enclosure consisting of four vertical tubes (6) and three horizontal tubes (7) that close the side faces and back face. On the front side there are arranged a chain (8) with hook.

Vertical pipes come out of the oblique uprights that, after suffering a curved join the elements of the upper enclosure, constituting a railing (9).

At the ends of one of the side sides of the base, for its bottom, there are two prismatic appendages (10), of the that emerge horizontal axes on which they are mounted cylindrical bodies constituting guide wheels (11). In the middle on the other side of the base another axis is fixed on which install a wheel (12) of somewhat larger diameter and whose band of Rolling consists of a pneumatic element.

The staircase is completed with a guide (13) consisting of a partially closed "U" profile that is fixed horizontally to the building, and on which the guide wheels can slide.

Claims (1)

1.
