Description

Multi-functional combination platen

Technical field

The utility model relates to a kind of platen of usefulness of reading, write, work of being convenient to, and especially is installed in the multi-functional combination platen of using on the carrier.

Background technology

The platen that uses on the market now, its main version do, a plate body is articulated on the handrail with chair one side through hinge, utilizes the rotation of hinge, with the mode of turnover, realizes the horizontal development of plate face and pack up.There is following defective in the platen of present this structure:

1, plate body is connected with armrests with screw through hinge; Do not possess the repeatedly function of dismounting; Plate body makes up, separates not easy with armrests, it is limited not only to cause chair independently to use, and platen can only be fixed on the single handle seat chair; Can not flexible configuration on furniture such as other chair, cause service efficiency not high.

2, be limited by the influence of self gravitation and activity space, the plate body design is less than normal, not steady, is difficult to satisfy the requirement of the normal posture of learning, writing.

3, receive folded must the article on the plate face all being taken away, just can pack up the plate face, personnel's in-out seat is inconvenient in the course of work.

4, from plate body maximization design philosophy, hinge can only be as far as possible near the plate body side, and support can not be done or multiple equilibrium support at 2, causes plate face bearing capacity little, the poor practicability in the studying or living.

5, rotational angle is limited, and it is little that the user passes in and out the space, uses inconvenient.

6, plate face angle control poor effect causes the plate face under the effect of external force, to move easily, causes the potential safety hazard of article on the table top.

7, the plate face is after load-bearing, and plate face rigidity is poor, horizontally rotates instability, causes the potential safety hazard of article on the plate face.

For addressing the above problem, the applicant has applied for a kind of patent that makes up platen, and this combination platen is convenient to frequent dismounting; Random collocation prop carrier; Use steadily reliably, sound construction, weight capacity are strong, the multi-angle location, possess the plate face further expand function, receive folded convenient, but this platen folding after; Flap hides the control device for pivoting of plate body, uncontrollable, the orientation angle of platen; Secondly its function is still perfect inadequately.
