Description

Have collapsible school bag supporting plate and extending Table top type desk

Technical field

The utility model relates to a kind of student and uses desk, particularly is fit to the desk that students in middle and primary schools use.

Background technology

The desk size of the use of middle and primary schools is all little at present, particularly along with student's growth, the increase of student's school bag capacity, brought a series of problems: first school bag capacity is big, the basic nothing of the drawer of desk is held, and school bag is placed in the place that does not also make things convenient for the student to use in the classroom, and some classmate is placed on the ground, and is very unhygienic, the classmate who has is placed on the chair, occupied effective usable floor area of chair, sat for a whole day semi-load, will have a pain in the back.It two is, because the space in classroom is limited, and the student is a lot, and in order to hold more student, the area of desk can not be too big, when students is used, is difficult to unfold limbs, and has a strong impact on sitting posture.These problems had both influenced the body development of students, had also influenced the learning efficiency of students.

Summary of the invention

During the technical problems to be solved in the utility model, at being to solve the place that existing desk and chair is not enough put school bag, and the big inadequately problem of the special-purpose desk of student, a kind of have collapsible school bag supporting plate and extending Table top type desk are proposed.

The technical solution of the utility model is such:

A kind of have collapsible school bag supporting plate and an extending Table top type desk, distribute and paired support (1) about comprising, desktop (2) is positioned at support (1) top, it is characterized in that: the both sides of desktop (2) are equipped with hinge (3), by hinge (3) extension table (4) is installed, in the bottom of support (1) hinge (5) is installed, by hinge (5) a school bag supporting plate (6) is installed, the school bag supporting plate can be installed in the either side in the support outside, make it have two kinds of location status of opening and closing, when opening, meet at right angles with described support.

Adopt desk improvement project of the present utility model, the carriage that can place school bag is arranged, and allow desktop can stretch some length in the side of desk.Can more effectively utilize the shared space of desk like this, student's school bag has the place to put: desktop can also be stretched out in the class; Desktop can be folded up in the time of after class; When classes are over, schoolbag bearer also can fold, and recovered the size of original desk again.Neither account for too many space, allow the student that bigger desktop study is arranged again, the place of placing school bag in addition can make things convenient for the student to enlarge effective usable floor area of desk significantly, makes things convenient for the student to form good sitting posture.

The specific embodiment

As shown in Figure 1, desk described in the utility model, distribute and paired support (1) about comprising, one desktop panel (2) is positioned at the support top, also includes a school bag supporting plate (6), and described school bag supporting plate is installed in the either side in the described support outside by folding hinge (5), make it have two kinds of location status of opening and closing, when opening supporting plate, supporting plate and described support meet at right angles, and the student can be placed on school bag on the supporting plate.Because supporting plate is positioned at the below of desktop, do not influence other desks of periphery, utilized the space fully.

Fig. 3 supports hinge for a kind of 90 degree turnovers that cooperate the utility model to implement.When the folding angle is 0 when spending, shown in Fig. 3 a, there are the angles of 90 degree between 1/4th projections that semicircle piece that stretch out rotating shaft inner core end and rotating shaft outer casing end are provided with.After hinge was opened 90 degree, shown in Fig. 3 b, the semicircle piece rotated with 1/4th projections to clockwise direction and contacts, and makes hinge can't continue to open.When closing, lift hinge plate as the direction of arrow among Fig. 3 b, the semicircle piece rotates to counterclockwise and separates with 1/4th projections, is returned to collapse state.

The utility model also can be installed extension table (4) in the either side or the both sides of described desktop panel both sides.The extension table with can take hinge (3) connected mode being connected of desktop; Like this,, the extension table can be launched to become horizontal with desktop, enlarge the area of desktop further if space on every side allows.Fig. 4 has provided the structural representation of support hinge commonly used.After being 180 degree states by the shown position turnover, two horizontal rotating shafts can be rotated, turnover before and after forming.This hinge is fit to be installed on the side plate of desktop.

The hinge that Fig. 3 and Fig. 4 provide is prior art.

Either side about extension table and school bag supporting plate all can optionally be installed in flexibly.

The paired support of desk described in the utility model can be for a pair of or two pairs.Distribute about being, and be axle, be symmetrically distributed with the center line of desktop.

When support when being a pair of, that Fig. 2 provides is another embodiment of the present utility model.At this moment support (7) be about the adjusting support of each liftable height, the mechanism of lifting can be taked height-adjustable arbitrarily principle of the prior art.As: support is divided into two sections, and each end is provided with rectangular groove, and two sections can be fixed with screw by the groove of intersection, and the length when the coincidence position of adjusting two sections just can have been adjusted the total height of support.The student that so just can be fit to different heights is fixed on school bag supporting plate (8) on the support (7) by hinge (9).

When support is two pairs, as shown in Figure 1, about each is a pair of, at this moment, described supporting plate just with the support of either side wherein to contacting, two contact positions are promptly just arranged, therefore, can adopt two folding hinges are installed, make that the support strength of supporting plate is better.

In order to prevent that arm from have a down dip the extension desktop, can be equipped with rotatable bracing frame (10) at the back side of desktop (2) when the extension table is exerted pressure.
