Description
Technical field
It is espespecially a kind of to contain at least two ladder and each pedal of each ladder be in phase the utility model relates to a kind of ladder
Pivot in unison is between adjacent two straight-bars to fold the ladder being laterally extended for folding or being unfolded.
Background technique
Ladder is the common auxiliary tool of daily life, and operation strategies are quite extensive, and main purpose is for using
Person can be more than the various operations of eminence progress of personal height, such as roof decoration, whitewashing, replacement lighting apparatus, storage item
Product etc..The type of ladder is in addition to general ladder (leaning to type ladder) or A font ladder are (by the top connection group of two ladder of front and back at present
At and the bottom expansible branch of two ladder) outside, more there is design to have both the ladder for folding closing function or upward Telescopic.
However, ladder used at present only has single ladder (i.e. foot-operated board width), can only be climbed for a people, therefore user is each time
Job area (or width) after climing up the ladder is relatively limited, when the job area (such as lateral distance) of eminence is larger, uses
The branch position that each subjob of person must first place ladder climbs up an operation wherein subrange again, therefore entire operation model
Multiple operation must be often divided by, which enclosing, to complete, i.e. user must constantly climb down to move ladder and climb up again operation, so not
But increase the activity duration, and user must climb ladder up and down and expend physical strength；In addition, existing ladder can only be climbed for a people
Climb, when have two people or more than will climbing ladder is to same high-rise working simultaneously when, (such as two people are synchronous to lift an article), then two people must divide
Not Shi Yong a ladder and parallel be set with could complete；Above situation not only causes the trouble and puzzlement of user, more influence ladder
Service efficiency.
Utility model content
The main purpose of the utility model is to provide the ladders that one kind can be laterally extended, and are to utilize at least three straight-bars

To the side of user's ladder)；Wherein at least one intermediate straight-bar 22 of this at least three straight-bar 20 is further respectively provided with
The opening of two reversed and back-to-back grooves 70 and two grooves 60 is to be respectively facing each pedal 30 set between two straight-bars, and make
First pivot 40 of the transverse ends 31 of each pedal 30 is located in the one in front and one in back two side walls of each longitudinal groove 70；As Fig. 3,
6, shown in 9,12, when each pedal 30 is pivoted by the first pivot 40 or the second pivot 50 with the pivot between the two neighboring straight-bar 20
When turning to fold and fold to form first or second folding collapse state, which can exist side by side in opposite directions by merging simultaneously
Make each pedal 30 is foldable to fold and be embedded in each groove 60,70, the folding that can more promote each ladder 10 folds effect.
In addition, the arrangement mode of set more pedals 30 is to include on each ladder 10 between two neighboring ladder 10: horizontal
To horizontal extension mode as shown in Fig. 1-3 or Fig. 7-9 or between transverse direction poor extension mode it is or horizontal as shown in Fig. 4-6 or Figure 10-12
To mode between horizontal extension or poor extension mode combination but do not limit.
With reference to Figure 21, Figure 22, each pedal 30 set by each ladder 10 is further designed to a gradient pedal 30a, the gradient
Pedal 30a is with a section of falling U-shaped but there is a shorter front support leg 301, a longer rear leg 302 and one to turn forward
The inclined-plane 303 of angle is attached between the front support leg and the top of rear leg and is provided as foot-operated face；When each straight-bar of each ladder 10
20 vertically when standing on ground, and the inclined-plane 303 of each gradient pedal 30a is that a heeling condition for turning forward angle is formed with ground
As shown in 21 figures；When each ladder 10 each straight-bar 20 inclination stand on ground and (such as lean against on wall but do not limit) in use,
The inclined-plane 303 of each gradient pedal 30a is to form horizontality with ground to ride for user is convenient.
With reference to Figure 23-Figure 28, wherein first pivot 40 set by the transverse ends 31 of each pedal 30 be hubbed on it is each straight
(refer in this front side wall towards user's ladder when in the one in front and one in back two side walls of the longitudinal groove 60 (70) of bar 21 (22)
Side), pivot hole 80 is for respectively corresponding pivot after pivot hole 80a before the front side wall of the longitudinal groove 70 is equipped with one and rear wall are equipped with one
If end 42 after a front end 41 and one of first pivot 40, wherein the preceding pivot hole 80a is further formed a cucurbit pore structure
And the lower hole 82 being connected to hole 81 on one and one with hole 81 on this, wherein hole 81 is and the rear pivot hole 80 on this
In the same horizontal position (as shown in figs. 23-25) on each straight-bar 21,22, make the front end 41 of each first pivot 40 can be in the preceding pivot
Upward and downward displacement is in the 80a of hole to be located on this in hole 81 or in the lower hole 82 (as shown in Figure 24,27).When each pedal 30
The front end 41 of first pivot 40 is located on the upper hole 81 of the preceding pivot hole 80a then end 42 and is located at corresponding rear pivot hole 80
When upper (as shown in figs. 23-25), each pedal 30 pivot in unison can fold between two neighboring straight-bar 20 to fold and form first
Or second fold collapse state；When each straight-bar 20 of each ladder 10 obliquely stand on ground use (as shown in figures 26-28) and
When each pedal 30 is by user's foot pressure (as shown in arrow A in Figure 26), the front end of the first pivot 40 of each pedal 30
41 can be shifted downward in the lower hole 82 of the preceding pivot hole 80a by the upper hole 81 of the preceding pivot hole 80a, so that each pedal
It is foot-operated convenient for user that 30 foot-operated face and ground form horizontality supplier.
With reference to Figure 23, Figure 26, when each pedal 30 further props up after having a front support leg 304, one with a section of falling U-shaped
Foot 305 and a foot-operated face 306 are attached between the front support leg and the top of rear leg for foot-operated in use, the front support leg 304
Leading flank is further provided with a fillet surface 304a and the trailing flank of the rear leg 305 is further provided with a fillet surface 305a, so that
