Description

A kind of multifunction seat

Technical field

This application involves technical field of furniture tools, in particular to a kind of multifunction seat.

Background technique

Now in daily life, chair is widely used in family life as a kind of thing to sit on.Current chair When general structure: then the rear feet of pair of right and left forefoot and pair of right and left is equipped with one at the top of forefoot and rear feet The seat board of block entirety is connected with a chair back in rear feet.Such chair-function is more single, can only be as a kind of thing to sit on With.And in family life, the same apparatus of ascending a height of a ladder is generally required sometimes, is convenient to the needs such as installation electric light and is ascended a height Place.But general ladder is all that volume is larger, it has not been convenient to be placed for a long time indoors.If placed indoors, in this way It will lead to interior space reduction, ladder places the problems such as inconvenient.

A kind of climbing chair is disclosed in the open file of Publication No. CN202981078U, the front foot including pair of right and left The rear feet in portion and pair of right and left, the rear feet are connected with the chair back, are equipped with lower pedal, the forefoot between the forefoot Top be connected with fore beam；It is connected with pedal between the rear feet, back seat plate, the front stall are connected at the top of the rear feet Plate and back seat plate are hinged and connected, and on fore beam, the climbing chair overturns in back seat plate and folds the back seat plate turnover folding At the ladder form that can be ascended a height after fore beam.

But the turnover structure of above-mentioned stool is connected merely by a hinge, axis when rotation where shaft It is in the outside of ladder climbing surface, which results in shafts to be easily damaged, and being exposed to external shaft can be to climbing people's production Raw unnecessary obstruction, such as: the trousers of climbing people are caught on, prevent climbing people climbs state from physical and mental investment, it is necessary to The moment is wanted to pay attention to coming the threat of the axis of rotation.

Utility model content

The purpose of this utility model is to enable shaft to be in ladder by the overturning of at least two rotation shaft regulated chair back It climbs in plane, to play the role of protecting scaler.

The above-mentioned purpose of the utility model has the technical scheme that a kind of multifunction seat, including Front and rear, the rear portion are connected with the chair back, and the rear portion turnover folding forms the ladder shape that can be ascended a height on the front State, which is characterized in that two-axis adjuster is provided between the front and the rear portion, the two-axis adjuster includes substrate, It is provided on the substrate and the first rotating shaft of front rotation connection and the second shaft being connect with the posterior rotation；

The top of the front is arranged in the first rotating shaft, and the top at the rear portion is arranged in second shaft；

Under stool state, the substrate is in stool surface；Under ladder state, the substrate is in ladder and climbs face It is interior.

Preferably, the two-axis adjuster further includes that be arranged in the front and the first rotating shaft cooperate first embedding Enter block, further includes the second embedded block that the rear portion and second shaft cooperation are set；First embedded block with it is described Front is fixedly connected, and second embedded block is fixedly connected with the rear portion.

Convenient for the fixation of shaft, and can also Convenient stool and shaft fixation.

Preferably, surface side is close to rear portion cooperation in the front is considered as one section of folding line, the folding line has Vertical portion and rake have an engaging angle between the vertical portion and the rake.

Stool convenient for being under ladder state can quickly become stool, can quickly engage when exactly fold.

Preferably, the front has a frame matrix, there is a horizontal pedal in the middle part of the frame matrix, it is described Pedal covers the rear part of the frame matrix.

There are the regions that foot is placed convenient for the people that takes one's seat for front.

Preferably, the chair back is fitted closely with the front under ladder state, and the chair back end and ground Between with one guard space.

Protect the integrality and aesthetics of the chair back because in documents the chair back needs land, this allow for as Backrest can be damaged when stool.

Beneficial effects of the present invention:

Advantage in structure is: can be used as while conventional chair can use again as ladder form, so that climbing chair Functional diversities, and facilitate placement, it is simple and practical.

When capable of most importantly making as stool, shaft, which is embedded in stool surface, ensures that stool surface is smooth；As When ladder, shaft insertion ensures that the surface of tread is smooth in ladder surface.

Protect the safety of operator.
