Abstract

The utility model relates to a table, especially a table with changeable tabletop size, comprising a tabletop plate and table legs. The table top plate comprises a substrate, four blocks of additional plates and a hinge. The substrate is a square plate, and the four additional plates are all triangular plates. The additional plate is formed by cutting along the diagonal line of a plate which has the same size and shape as the substrate. The four edges of the four additional plates, which form the original plate are respectively hinged to the four corresponding square edges of the substrate through a hinge. A plane locating rod is disposed between the substrate and the additional plates.

Description

A kind of desk that changes the desktop size

Technical field

The utility model relates to a kind of desk, is meant a kind of desk that increases or reduce the desktop area especially.

Background technology

Desk in the market is of a great variety, and with table, mahjong table, chess and card table or the like, these desks have brought a lot of convenience and enjoyment really to people's life and amusement such as big snack table, old-fashioned square table for eight people, bar; Receive liking of numerous users deeply, but above-mentioned table type is the moulding of dispatching from the factory basically, no matter be our employed dining table, desk or desk or the like; Its length scale is all fixed, and desktop is amplified, and also there is certain weak point in use in it; The thing of putting when needs after a little while, it is too wide that desktop seems, the thing of putting when needs is a lot; Seeming again, desktop is crowded not enough, and is very inconvenient, and when the increase number of users causes desktop to crowd; Also can only change desk, can cause inconvenience to a great extent to the user like this.And all kinds of table also is one one usefulness basically, and such as mahjong table, chess and card table, people have spent many expenses to buy, but when not using them, this type table also can only leave unused there, has so not only wasted but also taken a lot of spaces.

The utility model content

The utility model provides a kind of and the product conventional tables same nature; The utility model provides a kind of desk that changes the desktop size; Its technical problem underlying to be solved is: the desktop size of conventional tables is fixing; Can't change the desktop size, and the problems that being not easy to of causing closed and used flexibly in aspect the different purposes and different field.

For solving the problems of the technologies described above; The technical scheme that the utility model adopted is: the utility model provides a kind of desk that changes the desktop size; It comprises desktop and table pin, and it is characterized in that: said desktop comprises substrate, four add-in cards and hinge, and said substrate is a square plate; Four said add-in cards are triangular plate; Said add-in card is that a plate identical with said size of substrate, shape is cut out to divide along diagonal and formed, and four limits that constitute former plate on four said add-in cards are hinged on corresponding square four limits of said substrate through said hinge respectively, are provided with the plane positioning bar between said substrate and the said add-in card.

Optimal way: said plane positioning bar be hinged on the said substrate with corresponding another face of desktop on; Said plane positioning bar can be along rotating with corresponding another face of desktop on the said substrate; With the corresponding backstay buckle that is provided with of said plane positioning bar, said plane positioning bar is fastened in the said backstay buckle with the relative other end of an end that is hinged on the said substrate on the said add-in card.

Optimal way: said substrate is a rectangle, and said desktop is corresponding to be rhombus.

Optimal way: said substrate is a square, and said desktop is corresponding to be square.

Compare with conventional art; The beneficial effect of the utility model is: the utility model provides a kind of desk that changes the desktop size, can carry out concrete operations according to the needs of oneself during use, can make common table when original; Can increase when needing to increase desktop and be twice; When needing amusement, be folded down and can make mahjong table or chess table etc., thus the purpose of realization one-object-many-purposes.

The specific embodiment

In order can goal of the invention, technical scheme and the beneficial effect of the utility model to be carried out more in detail, to describe clearly, below will combine accompanying drawing and preferred embodiment that a kind of desk that changes the desktop size that the utility model proposes is done more to specify.

Shown in Fig. 1 to 3, the utility model provides a kind of desk that changes the desktop size, and it comprises desktop 10 and table pin 20.

Wherein, said desktop 10 comprises substrate 11, four add-in cards 12 and hinges 13.

Said substrate 11 is a square plate.

Four said add-in cards 12 are triangular plate, and said add-in card 12 is cut out branch with said substrate 11 sizes, plate that shape is identical along diagonal by one and formed.

Four limits that constitute former plate on four said add-in cards 12 are hinged on corresponding square four limits of said substrate 11 through said hinge 13 respectively, by said hinge 13 four said triangle substrates 12 are rotated up and down around the limit of corresponding said substrate 11.

Be provided with plane positioning bar 14 between said substrate 11 and the said add-in card 12, can said add-in card 12 be positioned at the position that flushes with said substrate 11 by said plane positioning bar 14.

A kind of preferred embodiment of said plane positioning bar 14: said plane positioning bar 14 be hinged on the said substrate 11 with corresponding another face of desktop on; Said plane positioning bar 14 can be along rotating with corresponding another face of desktop on the said substrate 11; On the said add-in card 12 with the said plane positioning bar 14 corresponding backstay buckles 141 that are provided with; Said plane positioning bar 14 is fastened in the said backstay buckle 141 with the relative other end of an end that is hinged on the said substrate 11, thereby reach said add-in card 12 is positioned.

As shown in Figure 4, be the utility model collapse state partial schematic diagram, wherein, said add-in card 12 upsets make things convenient for mobile, the folding and unfolding of the utility model on said substrate 11.

As shown in Figure 5; Deployed condition partial schematic diagram for the utility model; Wherein, said add-in card 12 flushes with said substrate 11 each other, when the desktop area of the utility model is in maximum; Its desktop area is the twice of said substrate 11, and said add-in card 12 is positioned at the position that flushes with said substrate 11 by said plane positioning bar 14.

As shown in Figure 6, be the deployed condition partial schematic diagram of the utility model, wherein, said add-in card 12 hangs from above below said substrate 11, and the desktop area of the utility model equals the area of said substrate 11.

As shown in Figure 7, the utility model in the specific implementation, said substrate 11 is a rectangle, said desktop 10 is corresponding to be rhombus.

As shown in Figure 8, the utility model in the specific implementation, said substrate 11 is a square, said desktop 10 is corresponding be square.

Comprehensive the above; The technical scheme of the utility model can fully effectively be accomplished the foregoing invention purpose; And the structural principle and the principle of work and power of the utility model all verified in an embodiment fully, and can reach the effect and the purpose of expection, and the embodiment of the utility model also can carry out conversion according to these principles; Therefore, the utility model comprise all in claim, mention in the scope all the replacement contents.Any equivalence of in the utility model claim, being done changes, and all belongs within the claim of this case application.
