Summary of the invention
The purpose of this utility model is in order to solve too late, the inconvenient height shop problem of usefulness ladder of people's height in the engineering, a kind of chair ladder dual tool of reasonable in design is provided, can be used as seat and use, can be used as again short ladder through the upset variation and use, safe ready does not take up room.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of chair ladder dual tool, comprise the chair back, the rear foot that is connected with the chair back, and the forward foot in a step, seating pad, it is characterized in that described seating pad by front backing plate be connected backing plate and connect by articulated manner, the width of rear backing plate is greater than the width of front backing plate, between the forward foot in a step and the rear foot, establish a crura intermedium that tilts to the back lower place, also be provided with the pedal parallel with seating pad between the forward foot in a step and the rear foot, described crura intermedium is divided into front and back crosspiece two parts, rear foot lower end is provided with base plate, and the side of the forward foot in a step is provided with the long pin button that connects.When using as seat, crura intermedium is divided into two parts of front and back crosspiece and is combined, and is linked by the short circuit pin and to connect fixingly, and front backing plate and rear backing plate are in the same plane; When using as ladder, rear backing plate and front backing plate turn over turnback take pin joint as the point of rotation, even rear backing plate turn-over is positioned at the top of front backing plate, the upper end of the chair back goes to the front shelves of ground and the forward foot in a step, crura intermedium as the support of ladder, pedal namely becomes the ladder pedal, and the gradient of ladder is determined by the angle of inclination of crura intermedium; The width of rear backing plate is greater than the width of front backing plate, and when using as ladder with assurance, the ladder bottom has enough front and back span and places safety.
As preferably, the rear shelves in the described crura intermedium in the past backing plate and rear backing plate hinged place play downward rear and extend, and link into an integrated entity with the base plate of rear foot lower end.Be straight shelves after the front shelves of crura intermedium, rear shelves merge, when using as ladder, front shelves, rear grade be in one with ground oblique line at an angle on, this oblique line is exactly the both sides batter post of ladder.Base plate is positioned at the top doing the ladder time spent, can be used as a pedal and uses, and also can be used as the platform of place tool, can be designed to the flat chassis structure as the platform of place tool.
As preferably, described crura intermedium front crotch divide and the forward foot in a step between be provided with horizontal cap ned, cap ned is positioned at the below of pedal.Cap ned is a kind of reinforcement structure, owing to as terraced chair dual tool, need turnover during use, overall construction intensity must be strengthened.
As preferably, a side of the described chair back is provided with the pin-and-hole that is located by connecting, and this pin-and-hole that is located by connecting connects the pin button and cooperates with long.When chair launched to use as ladder, because human body steps on pedal, it was fixed easily to shamble as the ladder rear foot, and the chair back is exactly the rear foot of ladder, the stability when using the length of one or both sides setting to connect the pin button can to guarantee as the ladder state.
As preferably, two parts before and after described pedal is divided into, front running board are fixed between the forward foot in a step and crura intermedium front crotch divide, between the rear shelves part of bumper step in the rear foot and crura intermedium.When the distribution of front running board and bumper step will guarantee to use as ladder, the distance between each pedal equated.
As preferably, the height of the described chair back equals forward foot in a step height, front plate thickness, rear plate thickness sum.Because the chair back is used as the ladder rear foot, when using as ladder, each strong point of bottom must be in the same plane.
As preferably, be provided with short circuit pin button between front and back crosspiece two parts that described crura intermedium is divided into.The structure of short circuit pin button can have multiple, such as bolt-type, and buckle-type, hinge button etc.
The beneficial effects of the utility model are: both can be used as the seat of rest usefulness, the height that can be used as again the people not as good as but be not suitable for using in the working environment of long ladder and finish aerial work, safe ready, one-object-many-purposes.
