This invention relates to an escalator outer decking, and more particularly, to an easily dismantled escalator outer decking.
Outer decking is a necessary part of an escalator or a moving walkway. The outer decking needs to be dismantled for easy replacement of parts during maintenance. There are several ways of securing the outer decking of an escalator or a moving walkway at present. One is that the outer decking 1′ is secured to a handrail system bracket 5′ by T-shaped bolts 12, see
It is an objective of the present invention to provide an escalator outer decking, which has good configuration and can be easily dismantled during maintenance.
The foregoing objective is attained by the easily dismantled escalator outer decking of the present invention.
According to the present invention, an escalator includes a handrail system bracket, a balustrade panel and a balustrade panel clamping member; and an escalator outer decking includes a cover plate, a first bracket, a retention member and an insertion strip. The first bracket is mounted on the handrail system bracket. The retention member has an open end and a closed end; the closed end of the retention member is secured to the underside of the cover plate while the open end is connected to the first bracket in a manner of embedding or snapping. The insertion strip is wedged between the cover plate and the balustrade panel.
When disassembling, the cover plate and the retention member can be taken down together by removing the insertion strip first and then uplifting the cover plate and the retention member or pushing them towards the balustrade panel.
In one exemplary embodiment, the manner of connecting the retention member to the first bracket is that at the side closest to the balustrade panel, a crooking portion that faces away from the balustrade panel is formed at the end of the retention member, and a gap that faces towards the balustrade panel, into which the crooking portion can be inserted, is formed correspondingly on the first bracket; and at the side away from the balustrade panel, a projecting portion that faces away from the balustrade panel is formed at the end of the retention member, and a groove that faces towards the balustrade panel, into which the projecting portion can be fitted, is formed correspondingly on the first bracket. In the illustrative embodiment, the retention member and the first bracket can be taken down together by pushing them towards the balustrade panel. A second bracket may also be provided between the cover plate and the balustrade panel clamping member. In the illustrative embodiment, the second bracket is snapped onto the balustrade panel clamping member and is secured to the underside of the cover plate for example, by screws.
In another embodiment, a leaf spring is provided between the retention member and the first bracket to hold the retention member in place. Preferably, the leaf spring is upside-down V-shaped.
Alternatively, the retention member and the first bracket can be connected in such a manner that at the side closest to the balustrade panel, a bulge that faces towards the balustrade panel is formed at the end of the retention member, and a notch that faces away from the balustrade panel, into which the bulge can be fitted, is formed correspondingly on the first bracket; and at the side away from the balustrade panel, a projecting portion that faces away from the balustrade panel is formed at the end of the retention member, and a groove that faces towards the balustrade panel, into which the projecting portion can be fitted, is formed correspondingly on the first bracket. In yet another embodiment, the side of the first bracket that is closest to the balustrade panel is upright or curved, such as S-shaped member.
In the illustrative embodiments of the present invention, the first bracket is mounted on the handrail system bracket, for example by bolts, and the retention member is secured to the underside of the cover plate, for example by bonding.
Additionally, in the escalator outer decking according to the present invention, the positions of the first bracket and the retention member are interchangeable.
In the escalator outer decking according to the present invention, the cover plate is mounted to the balustrade system bracket by simple connection such as, for example, embedding or snapping between the retention member and the first bracket. Comparing with the prior art, the escalator outer decking in accordance with the present invention is easy to assemble and disassemble. When disassembling, it is only needed to remove the insertion strip, then uplift the cover plate and the retention member or push them towards the balustrade panel, and thus the cover plate and the retention member can be taken down together. Such an escalator outer decking can be dismantled easily, and be free from structure of buildings and paratactic escalators.
Referring to
The retention member 2 has a projecting portion 17 that faces away from the balustrade panel 9, that is semicircular in its cross-section, at its end of the side away from the balustrade panel 9, while the first bracket 3 has a matched groove 18 that faces towards the balustrade panel 9, into which the projecting portion can be fitted, correspondingly. The function of such structure is similar to that of the crooking portion 15 of the retention member 2 and the gap 16 of the first bracket 3; both are used for limiting movement of the retention member and cover plate upwards, downwards or away from the balustrade panel 9. However, the difference between these structures is that the interface between the projecting portion and the groove is a cylindrical surface that permits the retention member 2 to rotate relative to the first bracket 3 for some degree (such design is more useful in the Second and Third Embodiments described below).
A second bracket 6 is provided between the cover plate 1 and the balustrade panel clamping member 10. It can be seen clearly in
An insertion strip 8 is wedged between the cover plate 1 and the balustrade panel 9. It can both fill the gap between the cover plate 1 and the balustrade panel 9 and hold other parts in place.
The retention member 2 is preferably π-shaped (or upside-down “U” shaped) in its cross-section, and may be formed by being extruded from a material such as aluminum alloy. The first bracket 3 may be made from spring steel or other similar material.
When disassembling, first the insertion strip 8 is removed, then the cover plate 1 and the retention member 2 are pushed towards the balustrade panel 9 for some distance, and then the retention member 2 is disengaged from the first bracket 3, from where they are connected, so the cover plate 1 and the retention member 2 can be removed together.
Referring to
Since the movement of the retention member 2 towards the balustrade panel 9 is prevented by the upright portion of the first bracket 3, the second bracket 6 in the First Embodiment is unnecessary here. An insertion strip 8 is also wedged between the cover plate 1 and the balustrade panel 9.
When disassembling, first the insertion strip 8 is removed, the cover plate 1 and the retention member 2 are lifted from the side close to the balustrade panel 9, and then the cover plate 1 and the retention member 2 are rotated relative to the first bracket 3 for some degree and the retention member 2 is disengaged with the first bracket 3 from where it is connected, thus the cover plate 1 and the retention member 2 can be taken down together.
Referring to
The way for removing the cover plate 1 and the retention member 2 is same as that of the Second Embodiment.
Referring to
The way for taking down the cover plate 1 and the retention member 2 is same as that of the First Embodiment.
Additionally, it will be understood by a person skilled in the art that the positions of the first bracket 3 and the retention member 2 can be interchanged in all of the above embodiments, i.e. the first bracket 3 can be secured to the underside of the cover plate 1 while the retention member 2 can be mounted on the handrail system bracket 5. In this case, the orientation of the connection portion (the crooking portion 15 and the gap 16, the projecting portion 17 and the groove 18, the bulge 19 and the notch 20) of the first bracket 3 and the retention member 2 may need to be adjusted accordingly.
The present invention may be embodied in other specific forms without departing from the spirit or essence thereof. Various adaptations and modifications of the invention will be obvious to those skilled in the art. Therefore, the presently discussed embodiments are considered to be illustrative and not restrictive, the scope of the invention will be indicated by the appended claims rather than the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
