Abstract

The utility model relates to a structure of a combined table and chair for teaching, which is mainly characterized in that two sides of the combined table and chair are respectively provided with an iron frame framework shaped like a G, the top surface of the upper section is combined with a table top of a drawer between the two frameworks, the top surface of the middle section is combined with a chair plate between the two frameworks, the front part between the two frameworks under the table top is combined with an upper transverse plate, and the rear part between the two frameworks under the chair plate is combined with a lower transverse plate to form a single combined table and chair; and an Jiong-shaped limiting frame plate can be locked on a framework below a chair plate of a chair by bolts, so that the latter chair can be connected and combined, and the connection and combination of any length can be carried out as required.

Description

Combined school desks and chairs

The tables and chairs of at present general teaching usefulness no matter be wooden make or metal is made, mostly separate with chair for desk, or desk and chair make one group, but one group of tables and chairs organizes between tables and chairs with another and separate separately, and just occupy certain space after making; This class teaching has several the shortcomings of the following stated with the structure of tables and chairs:

Tables and chairs separately, make teaching tables and chairs arrangement work, increase many difficulties and trouble with the housekeeping in classroom, as the alignment of tables and chairs etc., and the poor stability of tables and chairs also makes tables and chairs topple over the damage that causes tables and chairs easily.

2. tables and chairs just occupy certain space once making moulding, are that stock control, carrying all are problems, occupy etc. as the waste of storage space, and huge volume also makes carrying require great effort very much.

So how to make the tables and chairs of teaching usefulness can be combined into one to increase the stability of tables and chairs, and each of tables and chairs partly can simple and easy dismounting, conveniently store and carrying, connect into all lengths before and after can giving again, the tables and chairs of front and rear row can be connected and restriction mutually, and the area that tables and chairs contact with ground is able to the bigger contact-making surface of successive one-tenth, is the difficulty place that solves for this creation institute desire and increase steadiness.

This creator inquires into and studies sampling test because many shortcomings that above-mentioned habit formula is imparted knowledge to students and used with tables and chairs are the idea of thinking and improve innovation through designing in many ways, and repeatedly correction improvement, is release the utility model.

The owner will include two chase skeletons that are the G font, the desktop that contains drawer, a slice chair plate, and be the connection restriction deckle board of door character type and some bolt nuts etc. and form; Its owner will each seemingly be the chase skeleton of G word moulding in both sides with a shape, the end face of epimere in conjunction with a desktop that contains drawer between two skeletons, and in the end face in stage casing in conjunction with a chair plate between two skeletons, the place ahead is combined with a slice upper cross plate between two skeletons under the desktop in addition, and the rear is combined into single combined table and chair assembly in conjunction with a lower cross plate between two skeletons under the chair plate; Again can a door character type restriction deckle board with bolt lock knot on the skeleton under the chair plate of last tables and chairs reaches and connect and combination so that limit the desktop skeleton down of back tables and chairs, and the connection that must make any length according to the interior space is made up.Each interelement can simple and easy dismounting with convenient carrying with store, can check and balance again during combination and the contact-making surface on successive increase and ground, and reach suitable stability, make difficult toppling over line upon line and cause damage.

Main purpose of the present utility model, tying up to provides a kind of teaching tables and chairs capable of being combined that can simple and easy convenient disassembly store with carrying.

A purpose more of the present utility model, tying up to provides a kind of teaching tables and chairs capable of being combined that can be arbitrarily made with all lengths with the space in classroom.

Another purpose of the present utility model, tie up to provide a kind of tables and chairs to be combined into one and the front and back tables and chairs between can be connected combination arbitrarily, to increase the teaching tables and chairs capable of being combined that are difficult for toppling over damage with the contact area on ground and stability.

Below, now cooperate the graphic specific embodiment of enumerating, introduce structure content of the present utility model in detail, and the function and benefit that can reach as after.

Brief description of drawingsfig:

Fig. 1: be three-dimensional system diagram of the present utility model.

Fig. 2: be three-dimensional combination figure of the present utility model.

Fig. 3: be linking combination stereogram of the present utility model;

Fig. 4: the plane that is linking combination embodiment of the present utility model.

The figure number explanation:

10 ... chase skeleton 11 ... chair plate bonding pad 12 ... lining

20 ... desktop 21 ... drawer 30 ... the chair plate

40 ... restriction deckle board 50 ... last lower cross plate 60 ... bolt

70 ... nut

As shown in Figure 1, be three-dimensional system diagram of the present utility model, the owner will include desktop 20 that two chase skeletons that are the G font 10, one contain drawer, connection restriction deckle board 40 that a slice chair plate 30, is door character type, go up lower cross plate 50 and some bolts 60 and nut 70 etc. forms, wherein;

The skeleton inboard of the rear end face of chase skeleton 10 is established a chair plate bonding pad 11 respectively, and bottom and ground contacting part part then are arranged with two soft linings 12, and the downside of desktop 20 is combined with drawer 21 in addition; The owner will each seemingly be on the chase skeleton 10 of G word moulding with a shape in both sides, Duan side is provided with screw hole and combines with the drawer 21 of desktop 20 thereon, desktop 20 is set up between two skeletons 10, and chase skeleton 10 can set up a chair plate 30 between two skeletons on the bonding pad 11 of the end face in stage casing, the screw hole of crossing bonding pad 11 with bolt 69 bolts is in conjunction with fixing, in addition the place ahead is combined with a slice upper cross plate 50 with bolt 60 and nut 70 between two skeletons 10 under the desktop 20, and the rear also combines a lower cross plate 70 with bolt 60 and is combined into single combined table and chair assembly (as shown in Figure 2) between two skeletons 10 under the chair plate 30 with nut 70.

Can borrow bolt 60 lock knots on the skeleton 10 under last the tables and chairs chair plate 30 by door character type restriction deckle board 40 again as shown in Figure 3, so that the skeleton 10 that can limit under the desktop 20 of back tables and chairs reaches the combination of connection, and must do the connection combination (as shown in Figure 4) of any length according to the interior space.Each interelement can simple and easy dismounting with convenient carrying with store, can check and balance again during combination and the contact-making surface on successive increase and ground, and reach suitable stable unlikely toppling over and damage.

In sum, the utility model determines had breakthrough structure content in the past, and has the structure content of initiative, can reach flexible combination and the good progressive Practical Benefit that is difficult for toppling over damage of stability simultaneously again.
