Description
Technical field
The present invention relates to be called the technical field of the furniture article of " folding ", particularly tables and chairs.
Background technology
The known furniture item that may be folded on from one's body, can " amount to " by the user thus present the furniture item of flat configuration; This means that especially it can for example easily store by stacking, thereby it can easily transport in a large number, so that arrange to open configuration in the destination, and is arranged on desired locations in the expectation mode.
In the following description, will quote known collapsible object for the purpose of defective in the prior art in the outstanding technical field relevant with technical scheme of the present invention.
In known folding seat field, what can generally obtain has:
Make by plastic material to small part;
Has main truss, make by for example aluminium or other metals, described main truss comprises two parallel tubular parts, take a seat planar hinge and receive described tubular part, thereby between two parallel tubular shape parts, so that described tubular part has predetermined and fixing distance between axles, and can be used as the preceding supporting leg that takes a seat plane and load thereof and be used as back rest supports, described backrest forms especially and can particularly be fixed to tubular part by its fixed axis spacing; With
Second framework, also constitute by tubular part, the fixed axis spacing that also has the tubular part distance between axles that for example equals to constitute described main truss, described second framework is connected to described main truss by being arranged on the articulated elements that takes a seat the top, plane, and is connected to the rear end that takes a seat the plane by slide hinged.
When the chair of the above-mentioned type is in its fully open position, when promptly taking a seat the plane substantial horizontal, for closed chair, upwards promote to take a seat the front portion on plane, keep the backrest transfixion, rotate from going up thereby promote to take a seat the plane, and promote above-mentioned slidably articulated elements downwards along second framework in articulated elements (the described plane that takes a seat is connected to first framework by described articulated elements), simultaneously with respect to its rotation, thereby become vertical layout.Thereby, take a seat the plane, constitute the tubular part of main truss and constitute the tubular part of second framework substantially parallel, and adjacent especially, reduce thereby obtain significant volume with respect to the fully open position.
The major defect that above-mentioned known type folding seat is used is that it gives the unsettled sensation of people of sitting thereon usually.
Really, when the user sat down, one of such chair was under the stress that is produced by sizable power, at this moment, the user feel some parts of constituting chair motion beastly and move, described motion and move except make us unhappy, also produce the discomfort of certain degree.
In the table of known type, what can generally obtain has:
Have to be used to support and place the plane of object on the table;
Four upright legs that connect, are hinged to planar underside by cross bar separately in twos in its end.
In order to amount to the table of the type, must be the other way around with it, the upside by its contact plane for example places on the ground, and upright then leg must be towards the rotation of the bottom side of contact plane, and is parallel with described contact plane basically up to it.
Obviously, in order to open the Foldable table of known type, must be on the ground with the upside setting of contact plane, upright leg must be rotated into and be substantially perpendicular to described plane self, then must be with the upset fully of described table, thereby described table is placed on its upright leg restfully, and the free end of described upright leg contacts with ground.
First shortcoming of prior art is closed and opening operation need be overturn table, if table is very big and very heavy table, this may be very difficult operation.
Another shortcoming is that the upside of table repeatedly contact with ground after the operation of continuous open and close, and may be dirty owing to this reason, scratch or damage.
Another shortcoming is that the structure of the table of known type can not guarantee that enough rigidity is to open and effectively to prevent during by its upright leg support the horizontal vibration on plane when table.These vibrations not only make the user unhappy, and jeopardize the safe in utilization of table self; We can imagine the risk that placement liquid container is on the table overflowed.
Summary of the invention
