Abstract

A kind of rotatable downward folding can be fixed desk in bed, it is a kind ofly by accessory, to be fixed on the desk on bed, rear two legs are fixing in bed, top and desk panel at rear two legs are used rotatable shaft, and connect bottom and the desk panel of two legs afterwards with support bar, make support bar and panel and the rear leg triangle that meets at right angles, thereby replace the supporting role of the front support leg of conventional tables, junction, bottom at support bar and rear leg, use can be fixed openable design, when opening, desk panel will lose the supporting role of support bar, at gravity, be connected under the acting in conjunction of rotating shaft with the top of rear leg, desk front end can rotate downwards to be folded up, thereby the desk that soars occupies horizontal space in bed, can not limit the left and right scope of activities at human foot position.

Description

A kind of rotatable downward folding can be fixed desk in bed

Technical field

The utility model relates to a kind of desk household articles that is installed on hollow out bed, a kind of being fixed on hollow out bed specifically, the desk of rotatable downward folding.

Background technology

At present, known bed table is to be formed by leg and panel combination, whole placement in bed used, can occupy the activity space on bed like this, four legs also can limit the scope that moves left and right at human foot position, when people do not use, also need to move away from bed upper, this increases people's labour undoubtedly.

Summary of the invention

In order to overcome existing bed table, occupy space in bed, restriction human foot's scope of activities and be inconvenient to the problem of putting, the invention provides a kind of fixing in bed, the bed desk of rotatable downward folding, the rotatable downward folding of this bed table, so not only can not occupy horizontal space in bed, thereby can not allow the leg of desk limit the scope that moves left and right at human foot position yet, when people do not use, can also place in bed, greatly dwindle the space occupying in bed.

The utility model solves the technical scheme that its technical problem adopts: by groove, coordinate with the accessory of tongue, rear two legs of desk are fixed on to one side of hollow out bed, front two legs of conventional tables are removed, the bottom that connects panel and rear two legs with support bar, thereby support bar angle is tilted, with rear two legs and the panel triangle that meets at right angles, tie point at support bar and rear two legs, use can be fixed openable design, when opening, support bar loses and being connected of rear two legs, after adding, rotatable axle design is used in the junction of two legs and panel, like this, panel loses support, under effect due to gravity, and be rotated down, fold up.

The beneficial effects of the utility model are, can allow people use in bed desk, do not allow again the leg of desk limit the moving range at human foot position, can also freely fold up, fix in bed, greatly dwindle desk and occupy space in bed, be widely used in student and masses and learn in bed reading work.

Fig. 5 is the functional diagram of second embodiment of the present utility model

In Fig. 1,1. anglec of rotation button 2. panel 3. rotating shaft 4. rotary support angles are buckled 5. band nut screws 6. and are supported iron

7. plate groove button 8. tongue buttons

In Fig. 2,2.1 for the circular hole position 2.2 of tightening up a screw is for rectangular recess

In Fig. 3,3.1 is that circular hole 3.2 is that tongue 3.3 is the circular hole position of tightening up a screw.

In Fig. 4,4.1 is hollow out bed.

The specific embodiment

In Fig. 4, putting the little pillar on one side of hollow out bed into tongue buckles in 8 groove, matching board groove button 7 again, by the screw with in nut screw 5 through 3.3 the circular hole position of tightening up a screw in tighten up a screw circular hole position and Fig. 3 in 2.1 in Fig. 2, pass through again nut tightening, due to the folder power of plate groove button 7 with tongue button 8, thereby make desk fixing in bed.Support iron 6 tops are positioned on rotary support angle button 4, left and right, bottom opening portion fastens respectively 3.1 bottom circular holes in Fig. 3 again, support iron 6 and tilt, with tongue button 8 and panel 2 be right angled triangle.

In Fig. 5, support iron 6 left and right, bottom opening portions are outwards pulled open respectively, make them depart from 3.1 bottom circular holes of circle in Fig. 3, like this, desk panel 2 will lose the supporting role of supporting iron 6, adds tongue button 8 and the design of having used anglec of rotation button 1 and being connected of panel 2 rotating shaft 3, and panel is under the effect of gravity, front end, owing to not supporting, can rotate downwards and fold up.

Claims (3)

1. a rotatable downward folding can be fixed desk in bed, comprise leg, support bar, rotating shaft, its feature: the leg of desk one side is fixing in bed, leg is used rotating shaft to be connected with the junction of desk panel, with support bar, connect again the bottom of panel and leg, make support bar become hypotenuse, become a right angled triangle with desk panel with leg, form the supporting role of desk, and use and can fix openable design in the junction of support bar and leg bottom.

2. rotatable downward folding according to claim 1 can be fixed desk in bed, it is characterized in that: the junction by support bar and foot bottom fix openable design, make support bar that desk is played and be supported and freely converting of not supporting, again due to the rotating shaft of leg and desk, from can normal level being used with rotation, desk folds up downwards.

3. rotatable downward folding according to claim 1 can be fixed desk in bed, it is characterized in that: can install in bed, utilize rotating shaft, by the support of support bar and the effect of not supporting, convert, can make desk folding, dwindle desk and occupy the horizontal space on bed.
