Abstract
Discloses is a foldable ladder, comprising principal ladder bars, the ends of which are hinged with each other by means of principal hinging buttons; the hinge of the sides of the principal ladder bars can make the principal ladder bars furl foldable hinges or unfold the foldable hinges in the shape of the Chinese character<ren>. The unfolding of the principal ladder bars, the principal hinging buttons and the foldable hinges forms A-shaped principal ladder frames. Pedals are hinged between the corresponding principal ladder bars of the two principal ladder frames. The utility model is characterized in that: the pedals are divided into two parts and are connected by hinging buttons; supporting rods are hinged between the corresponding principal ladder bars of the two principal ladder frames; the supporting rods are connected with each other by the hinging buttons; the length of the supporting rods is more than any part of the pedals; a connecting rod passes through the hinging buttons of the pedals and the hinging buttons of the supporting rods to connect in series the pedals and the supporting rods; at least the hinging buttons of the pedals or the hinging buttons of the supporting rods can slide relatively along the connecting rod. The utility model can be folded and furled along the width direction, and thus the utility model is convenient to be stored and carried with function and reliability. Therefore, the utility model is applicable for the families and the decoration.
Description
[technical field]
The utility model relates to a kind of ladder, relates in particular to a kind of foldable ladder.
[background technology]
Common foldable ladder is when folding, and the terraced bar of the master of main ladder support can merge gathering around main hinge joint key, but can not draw in along the pedal direction between the main terraced bar, promptly folds on width, draws in.
[summary of the invention]
The purpose of this utility model is to provide a kind of foldable ladder that can fold, draw on width.
The technical solution of the utility model is: this foldable ladder, it comprises main terraced bar, main terraced boom end links to each other by the hinge joint of main hinge joint key, main terraced bar sidepiece is hinged to make main terraced bar draw or be the collapsible hinge of herringbone expansion in, main terraced bar, main hinge joint key and collapsible hinge constitute " A " font main ladder support upon deployment, link pedal between the terraced bar of corresponding master on two pairs of main ladder supports, it is characterized in that: described pedal is divided into two joints, and links to each other by hinged key; Also link support bar between the terraced bar of corresponding master on two pairs of main ladder supports, link to each other by hinged key between the support bar, the length of support bar is greater than the arbitrary joint in the pedal; One connecting rod passes hinged key on the pedal and the hinged key on the support bar, serial connection pedal and support bar, and in the hinged key and the hinged key on the support bar on the described pedal, one of them can make relative sliding motion along connecting rod at least.
The cross section of main terraced bar be " [" shape, " the opening side of [" shape is towards pedal, and its width is greater than the width of pedal; Longitudinal pitch between the pedal is greater than the length of corresponding pedal one joint.
The beneficial effects of the utility model are: in the utility model, pedal is divided into two joints, and links to each other by hinged key; Also link support bar between the terraced bar of corresponding master on two pairs of main ladder supports, link to each other by hinged key between the support bar, the length of support bar is greater than the arbitrary joint in the pedal; One connecting rod passes hinged key on the pedal and the hinged key on the support bar, serial connection pedal and support bar, in the hinged key and the hinged key on the support bar on the described pedal, at least one of them can make relative sliding motion along connecting rod, like this, make the upwards bending gathering of pedal and support bar, be implemented in folding on the width, gathering ladder by connecting rod, further reduce taking up room, be convenient to collect and carry.When using the utility model, the end user sets foot on pedal, make the ladder pressurized, as shown in Figure 1, pressure reaches support bar, support bar produces an outside tension force, outwards push main terraced bar, pedal then links the terraced bar of corresponding master securely, in fact, this structure produces a kind of self-locking effect, makes the utility model stable more, reliable.The cross section of main terraced bar be " [" shape, " the opening side of [" shape is towards pedal, and its width is greater than the width of pedal; Longitudinal pitch between the pedal is greater than the length of corresponding pedal one joint, and like this, the utility model can big limit invagination be folded, draw on width, even pedal is received fully to main " in [" shape groove of terraced bar.In a word, the utility model can fold on width, draw in, is convenient to collect and carry, and is practical, and reliable operation is suitable for family and fitment operation and uses.
[description of drawings]
Fig. 1 is the utility model schematic appearance;
Fig. 2 is the front elevational schematic of AA-BB part.
[specific embodiment]
With embodiment the utility model is described in further detail with reference to the accompanying drawings below:
According to Fig. 1 and Fig. 2, the utility model comprises main terraced bar 1, main terraced bar 1 end links to each other by main hinge joint key 11 hinge joints, main terraced bar 1 sidepiece is hinged to make main terraced bar 1 draw or be the collapsible hinge 12 of herringbone expansion in, main terraced bar 1, main hinge joint key 11 and collapsible hinge 12 constitute " A " font main ladder support upon deployment, hinge joint pedal 2 between the terraced bar 1 of the corresponding master on two pairs of main ladder supports, pedal 2 is divided into two joints, and links to each other by hinged key 21; Also link support bar 3 between the terraced bar 1 of the corresponding master on two pairs of main ladder supports, link to each other by hinged key 31 between the support bar 3, the length of support bar 3 is greater than the arbitrary joint in the pedal 2; One connecting rod 4 passes hinged key 21 and hinged key 31, serial connection pedal 2 and support bar 3, and hinged key 21 all can be made relative sliding motion along connecting rod 4 with hinged key 31; The cross section of main terraced bar 1 be " [" shape, " the opening side of [" shape is towards pedal 2, and its width is greater than the width of pedal 2; Longitudinal pitch between the pedal 2 is greater than the length of corresponding pedal 2 one joints.
In use, as shown in Figure 1, the end user can set foot on pedal 2; When folding, the terraced bar 1 of the master of main ladder support can merge gathering around main hinge joint key 11, makes pedal 2 and upwards bending gathering of support bar 3 by connecting rod 4 again, and two joints of pedal 2 take in " in [" shape cross section of the terraced bar 1 of corresponding master respectively.
