Description
Technical field
The present invention relates to field of furniture, the Collapsible rack that relates in particular to a kind of folding same table or stool and be used for same table or stool.
Background technology
Desk or stool are the furniture a kind of commonly used that is fixed up by flat board, supporting leg or other supporter, and it is made material and generally includes solid wood, glass, metal, plastics, stone material etc.Nowadays, desk or stool become important furniture indispensable in each family already, and people can have a meal on desk, write, work or placing articles etc.Along with the continuous increase of the size of population and remaining high of Housing Price, the area of people's inhabitation and life reduces day by day now, and desk is a more space consuming household articles.For conserve space, people can select less desk, but when running into the situations such as relatives and friends' party, stand does not usually satisfy again user demand; On the other hand, if select larger desk, not only larger floor space can be occupied, and when the mediocrity is few, the waste in space can be caused again.
The extensive use in people's work, studying and living along with desk or stool, desk such as computer desk, desk, desk etc. bring a lot of convenience to us, application demand along with people, comfortable, facility to desk also require more and more higher, for satisfying people's demand, energy is adjusted height and convenient and practical desk or the stool that reduces again floor space enjoys liking of people, so desk or the stool of height adjustable folding have occurred.
Be that 201220466262.3 Chinese patent discloses a kind of electric elevatable table such as the patent No., comprise left column and right column, described left column upper end is fixed with left shoulder, and the lower end is fixed with left lower margin, and described right column upper end is fixed with right shoulder, and the lower end is fixed with right lower margin; Between described left shoulder and the right shoulder entablature is housed fixedly, on described left column, right column and the entablature desktop is installed, described left column and right column include at least two tube connectors, at least part of connecting together between the described tube connector is equipped with respectively the motor and the lowering or hoisting gear that drive left column and right column lifting in described left column and the right column.The existing following defective of same table ubiquity:
(1) assembling of whole product usually need certain professional, need to be by the professional to the user scene with parts assembly and adjustment singly, so just increased personnel's cost to the seller.For such defective, people normally finish whole assembling before desk dispatches from the factory, and send with large packing and are carried to the buyer.And in whole assembling process, the installation requirement of its middle cross beam and column is the highest, and the structure of this part accounts for the packed and transported space most.But crossbeam and vertical rod directly are fixed together, and can't fold, and crossbeam also can't fold, and are inconvenient to like this pack, and cause transportation inconvenient.
(2) although described electric elevatable table has solved liftable problem; but when column loads on carrying overload with interior arbitrary load running; when its desktop that connects is run into windowsill; cabinet writes; when the child who plays waits; can't make fast response; must when reaching setting, load just can make a response; and this moment, desk may be to damage; child meets with security incident; the security of described product is inadequate; therefore in same table, increase a kind of protective device; realize column under any load operation conditions, if with it the desktop load that connects and change, system just can make a response and be necessary.
