Abstract

The utility model relates to a movable table for a lifting and folding bed, which comprises a pair of rotating supports installed on both sides of a lifting bed board through hinge pins, and a table top is fixedly installed on the top ends of the rotating supports; the lower end of each rotating support is in an inverted Y shape and comprises two arc branches, including an upper branch and a lower branch, the lower branch is connected with the tail end of a bed frame through a main spring, and the upper branch is connected with the tail end of the lifting bed board through an auxiliary spring; limiting stops are installed on both sides of the lifting bed board; the tail end of the lifting bed board is provided with a latch with an elastic resetting mechanism, and the unlocking or locking of the latch is controlled by a pull rope; and the movable table is installed at the rear part of the lifting and folding bed, and the lifting of the movable table can be controlled through the latch. When the movable table is not used, the movable table can be lowered and used as a tail baffle board of the bed, and the utility model has the advantage of space saving.

Description

A kind of folding bed drop table

[technical field]

The utility model relates to a kind of drop table, relates in particular to a kind of folding bed drop table.

[background technology]

People need sometimes to lie on a bed and read a book or the use notebook computer, also have when the nursing bed patient, and also be the cumbersome thing of part if do not have desk hello meal, hello soup.A kind of stand of placing is in bed arranged on the market, but this desk to place be not very steady in bed, all might knock desk over when the user moves health, and not the time spent also to look for special place to place, cumbersome.Other can be placed on movably Nursing table or too heavy of bedside, or take up space very much.Chinese patent " the multifunctional medical nursing bed " (patent No.: 97230340.5) disclosed a kind of movable Nursing table, but its structure is the pedestal that is provided with the table dormant pin in both sides, bed rear end, level and vertical two kinds of groove positions are arranged, when using desk, only need to insert in the vertical channel position table pin fixing, not the time spent, the table pin is inserted in the level trough position, also can do the tailstock baffle plate and use.This desk has solved the problem of placing, and neither be easy to but the table pin is fixed in the stopper slot of pedestal.

[summary of the invention]

For placement and the installation question that solves drop table, of the present utility modelly provide a kind of folding bed drop table.

Technical solutions of the utility model are: a kind of folding bed drop table comprises a pair ofly being installed in the runing rest of lifting bed bed board both sides by bearing pin that the top of described runing rest fixedly mounts a desktop; The lower end of described runing rest is down " y " type, comprises two arc bifurcateds: upper bifurcation and lower bifurcation; Described lower bifurcation is connected with the bedstead tail end by main extension spring, and institute's upper bifurcation is connected with lifting bed bed board tail end by auxiliary extension spring; Described lifting bed bed board both sides are equipped with positive stop; Lifting bed bed board tail end is equipped with the breech lock of band flexible restoring organ, and described breech lock is controlled it by stay cord and opened or locked.

Benefit of the present utility model is, this drop table is installed in the rear portion of folding bed, during use, only need just can control the lifting of drop table by breech lock, therefore the user lies on a bed and does not need the stranger to help just to operate, when not using at ordinary times, the drop table that fell can also be used as tailstock portion baffle plate and use, and has saved the space.

[description of drawings]

Below in conjunction with the drawings and specific embodiments the utility model is described in detail.

Fig. 1 is the perspective view of the utility model drop table when holding up;

Fig. 2 is the perspective view of the utility model drop table when falling.

[specific embodiment]

Referring to Fig. 1,2, a kind of folding bed drop table comprises a pair ofly being installed in the runing rest 1 of lifting bed bed board both sides by bearing pin 9 that the top of runing rest 1 fixedly mounts a desktop 2; The lower end of runing rest 1 is down " y " type, comprises two arc bifurcateds: upper bifurcation 3 and lower bifurcation 4; Upper bifurcation 3 is connected with lifting bed bed board tail end by auxiliary extension spring 6; Described lifting bed bed board both sides are equipped with positive stop 7; Described lifting bed bed board tail end is equipped with the breech lock 8 of band flexible restoring organ, and breech lock 8 is controlled it by stay cord and opened or locked.

The utility model is installed on a kind of folding bed and uses, and described folding bed is made up of bedstead, headpiece, tailstock plate, described bedstead and described headpiece, tailstock plate bottom-hinged; When described folding bed bed board when lying status is adjusted to the sitting posture state, described tailstock plate is to the front lower place translation; Bearing pin 9 is fixedly mounted on the described tailstock plate, runing rest 1 is that fulcrum constitutes a lever with bearing pin 9, be connected that 5 pairs of runing rest 1 lower ends of main extension spring impose downward backward power on lower bifurcation 4 and the described bedstead tail end, the 6 pairs of runing rests 1 of auxiliary extension spring that are connected upper bifurcation 3 and described tailstock plate rear end impose oblique upper power backward; When not using drop table, dead bolt was stuck in the desktop 2 when breech lock 8 was closed, and desktop 2 keeps motionless; When needing to use drop table, the folding bed bed board is adjusted to the sitting posture state, the pulling stay cord is opened breech lock 8, because the moment of main extension spring 5 and auxiliary extension spring 6 pulling force is greater than the moment of runing rest 1 and desktop 2 gravity, so support 1 and desktop 2 are upwards dug; In this process, the moment of support 1 and desktop 2 gravity diminishes gradually, and simultaneously, the moment of main extension spring 5, auxiliary extension spring 6 pulling force also diminishes gradually, because between upper bifurcation 3 and the lower bifurcation 4 certain angle is arranged, so the minimizing of the moment of torque ratio main spring 5 pulling force of auxiliary extension spring 6 pulling force is little; When runing rest 1 arrived positive stop 7 positions, the moment of runing rest 1 and desktop 2 gravity and the moment of main extension spring 5 pulling force were almost equal to zero, and drop table keeps stable state under auxiliary extension spring 6 and positive stop 7 effects; In the time will falling described drop table, the folding bed bed board is adjusted to lying status from the sitting posture state, the back bed board of described folding bed rises to oblique rear, main extension spring 5 forms opposite moment with auxiliary extension spring 6, this moment, the user only need touch desktop 2, described drop table can fall under the effect of self gravitation, closed breech lock 8 fixing described drop tables.
