Description
Technical field
The present invention relates to field of furniture, particularly relate to a kind of folding same table or stool and the Collapsible rack for same table or stool.
Background technology
Desk or stool, be that the one be fixed up by flat board, supporting leg or other supporter commonly uses furniture, it makes 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 the high of Housing Price, present people live and the area of life reduces day by day, and desk is a more space consuming household articles.In order to save space, people can select less desk, but when running into the situations such as relatives and friends' party, stand usually can not meet user demand again; On the other hand, if select larger desk, not only can occupy larger floor space, and when 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, along with the application demand of people, also require more and more higher to comfortable, the facility of desk, for meeting the demand of people, can adjustment height and convenient and practical reduce again floor space desk or stool enjoy liking of people, so there is height adjustable folding table or stool.
The Chinese patent being 201220466262.3 as the patent No. discloses a kind of electric elevatable table, comprises left column and right column, and described left column upper end is fixed with left shoulder, and lower end is fixed with left lower margin, and described right column upper end is fixed with right shoulder, and lower end is fixed with right lower margin; Fixedly entablature is housed between described left shoulder and right shoulder, described left column, right column and entablature are provided with desktop, described left column and right column include at least two tube connectors, connect together at least partly between described tube connector, in described left column and right column, the motor and lowering or hoisting gear that drive left column and right column lifting are housed respectively.The following defect of existing same table ubiquity:
(1) assembling of whole product needs certain professional usually, needs by professional on-the-spot by parts assembly and adjustment singly to user, so just increases the cost of personnel to seller.For such defect, whole assembling normally completes by people before desk dispatches from the factory, then with one large pack to send be carried to 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 packed and transported space most.But crossbeam and vertical rod are directly fixed together, cannot fold, and crossbeam also cannot fold, be inconvenient to like this pack, cause transport inconvenient.
(2) although described in electric elevatable table solve liftable problem, but column load is when carrying the arbitrary load running within overload, the desktop connected when it encounters windowsill, write cabinet, during the child etc. played, response cannot be made fast, just can must make a response when load reaches setting, and now desk may be damage, child meets with security incident, the security of described product is inadequate, therefore in same table, a kind of protective device is increased, realize column under any load operation conditions, as long as the desktop load be connected with it changes, system just can be made a response and is necessary.
Summary of the invention
