Abstract
The invention discloses a foldable up and down ladder and aims at providing the foldable up and down ladder which is simple in structure, low in manufacture cost, foldable, large in stepping surface and safe and convenient to use. The ladder comprises a left ladder frame and a right ladder frame which are parallel. A plurality of stepping boards (3) are arranged in parallel between the left ladder frame and the right ladder frame, and two ends of each of the plurality of stepping boards (3) are hinged to an upper ladder column (4) and a lower ladder column (5) respectively. The ladder is applied to the technical field of climbing tools.
Description
Technical field
The present invention relates to descending stair on a kind of folding.
Background technology
Ladder is the instrument for climbing, and is instrument common in daily life, generally by two long thick bars, does limit, and scansorial cross bar is crossed in centre.The field of application of ladder is very extensive, in ship domain, also usually use, such as on current a yacht, it is provided with two-layer deck, between one deck deck and tween deck, need to install ladder, visitor can conveniently walk by ladder on one deck deck and tween deck.Simultaneously, producer is in order to pursue higher safety factor, often ladder is fixed between two-layer deck, form fixed type stair, but this design will reduce the active area on one deck deck, particularly, on yacht, the active area on deck is very valuable, reduce the active area on deck and can impact yacht undoubtedly, reduced visitor's comfort level.
Summary of the invention
Technical matters to be solved by this invention is to overcome the deficiencies in the prior art, and descending stair on a kind of simple in structure, low cost of manufacture, the folding that collapsible, tread is large, safe and convenient to use is provided.
The technical solution adopted in the present invention is: the present invention includes the left ladder and the right ladder that be arranged in parallel, between described left ladder and described right ladder, parallel is shown some pedals, described left ladder and described right ladder form by the upper cleat stanchion be arrangeding in parallel and lower cleat stanchion, and the two ends of described some pedals are hinged with described upper cleat stanchion and described lower cleat stanchion respectively.
The two ends of described some pedals are all fixedly installed pedal bracket, and described pedal bracket and described upper cleat stanchion and described lower cleat stanchion are hinged.
The upper end of described lower cleat stanchion is hinged with fixed leg.
The lower end of described upper cleat stanchion is provided with pad.
On described upper cleat stanchion and described lower cleat stanchion, be provided with fixed orifice.
Described some pedals are hardwood plate.
The invention has the beneficial effects as follows: because the present invention has adopted folding design, the present invention includes the left ladder and the right ladder that be arranged in parallel, between described left ladder and described right ladder, parallel is shown some pedals, described left ladder and described right ladder form by the upper cleat stanchion be arrangeding in parallel and lower cleat stanchion, the two ends of described some pedals are hinged with described upper cleat stanchion and described lower cleat stanchion respectively, during use, the two ends of described lower cleat stanchion are relying on metope and ground, and described lower cleat stanchion has at least one end to keep relatively fixing, make again the lower end of described upper cleat stanchion rely on the ground, and make described some pedal maintenance levels, can described some pedals are up folding in the time of obsolete, reduced area occupied of the present invention, so, the present invention is simple in structure, low cost of manufacture, collapsible, than current stair, economized a large amount of floor areas, and more common ladder, increased again tread large, safe ready more in the process of using.

The specific embodiment
embodiment mono-
As shown in Figures 1 to 6, the present invention includes the left ladder 1 and the right ladder 2 that be arranged in parallel, between described left ladder 1 and described right ladder 2, parallel is shown some pedals 3, described left ladder 1 and described right ladder 2 form by the upper cleat stanchion 4 be arrangeding in parallel and lower cleat stanchion 5, the two ends of described some pedals 3 are hinged with described upper cleat stanchion 4 and described lower cleat stanchion 5 respectively, in the present embodiment, described pedal 3 has ten, and ten described pedals 3 evenly and be arranged in parallel between described left ladder 1 and described right ladder 2.
The two ends of ten described pedals 3 are all fixedly installed pedal bracket 6, described pedal bracket 6 is hinged with described upper cleat stanchion 4 and described lower cleat stanchion 5, in the present embodiment, described pedal bracket 6 passes described upper cleat stanchion 4 and described lower cleat stanchion 5 by stainless steel bolt, realize thus hingedly, and on stainless steel bolt, be also socketed with corrosion-resistant steel sleeve pipe.
The lower end of described upper cleat stanchion 4 is provided with pad 8, and described pad 8 has anti-skidding effect, in the present embodiment, also with stainless steel bolt, described pad 8 is fixed on the ground, has further strengthened safety performance of the present invention.
On described upper cleat stanchion 4 and described lower cleat stanchion 5, be provided with fixed orifice 9, after described pedal 3 is turned up, described fixed orifice 9 on described upper cleat stanchion 4 and described lower cleat stanchion 5 is corresponding, at described fixed orifice 9, plugging latch can be fixing by cleat stanchion on described 4 and described lower cleat stanchion 5, has improved stability of the present invention.
Described some pedals 3 are hardwood plate, and the hardness of described hardwood plate is high, long service life, and easily processing, and good looking appearance is used and can not reduced the sight of the outward appearance of yacht on yacht, can also improve to a certain extent the class of yacht.
During use, the two ends of described lower cleat stanchion 5 are relying on metope and ground, and described lower cleat stanchion 5 upper ends are fixed on metope, make again the lower end of described upper cleat stanchion rely on the ground, and make described pedal 3 maintenance levels, can described pedal 3 is up folding in the time of obsolete, then latch is fixing by described upper cleat stanchion 4 and described lower cleat stanchion 5, has reduced area occupied of the present invention.
embodiment bis-
In the present embodiment, be with embodiment mono-difference: the upper end of described lower cleat stanchion 5 is hinged with fixed leg 7, in use, described fixed leg 7 is fixed on metope, the lower end of described lower cleat stanchion 5 props up ground, and because people steps down on described pedal 3, the power that described pedal 3 is subject to is downward all the time, and the lower end of described upper cleat stanchion 4 and described lower cleat stanchion 5 is all against on the ground, make the present invention deformation can not occur in the process of using.In the time of obsolete, can described pedal 3 is up folding, latch is fixing by described upper cleat stanchion 4 and described lower cleat stanchion 5 again, pulley is set simultaneously on top ceiling, with rope, pinion the lower end of described upper cleat stanchion 4 or described lower cleat stanchion 5, then rope is walked around pulley, so just the present invention can be sling, and takies not at all floor area.
The present invention is applied to the technical field of the instrument of climbing.
Although embodiments of the invention are described with practical solution, do not form the restriction to implication of the present invention, for those skilled in the art, according to this specification sheets to the modification of its embodiment and with the combination of other schemes be all apparent.
