Abstract

The utility model discloses a dual-purpose turnable table-chair which comprises a base 1, a panel 2, an armrest connecting rod 3, a supporting connecting rod 4, pins and a positioning device. The table-chair can be used as a table and a chair by overturning the connecting rods, a table and chair conversion process is simple, and the table chair is locked through the positioning pins when serving as the table or the chair to ensure that the structure is stable and reliable.

Description

A kind of turnover Dual-purpose table combined with seat

Technical field

Furniture technical field, particularly a kind of turnover Dual-purpose table combined with seat under the utility model.

Background technology

At present, known desk and chair can only be exercised a kind of single function, and desk can not use as chair, and chair can not be exercised the function of desk.

Summary of the invention

for the problem of above-mentioned existence, the utility model proposes solution, its technical scheme is: the cross section of panel is L shaped structure, and its outer upper surface can be used as desktop, and inner surface can be used as seat.Panel and base intersect by ribbed insert and support link the quadric chain (now base is equivalent to frame, and panel is equivalent to connecting rod, and ribbed insert and support link are equivalent to two side links) that constitutes by an active connection.When rotary panel is when to panel, upper surface (desktop) is parallel with base, now outer surface can be used as desk and uses; In the time that rotary panel is parallel with base to inner surface, inner surface can be used as chair and uses.By upset quadric chain, thereby panel 90-degree rotation has been realized the exchange of desk and two kinds of functions of chair.

When as desk, the alignment pin on left support connecting rod inserts in locating hole corresponding on ribbed insert under the effect of spring, realize when as desk, and fixing between support link and ribbed insert, now total is in stationary state.When as chair, the alignment pin that right support connecting rod is arranged on bracing frame inserts locating hole corresponding to ribbed insert, while having realized as chair, and fixing between support link and ribbed insert, now total is in stationary state.Except positioner is left support connecting rod is different with installation site on right support connecting rod, other structures are and are symmetrically arranged.

In the time that turnover double-purpose seat uses as chair, the handrail that v-shaped structure on ribbed insert can be used as chair both sides uses, and the bottom surface copline of v-shaped structure bottom in support link and base is as bracing frame, to improve the stressing conditions of ribbed insert and support link.

the beneficial effects of the utility model are: apply cleverly quadric chain and realized and not only can be used as desk but also can be used as the function that chair uses, and simple as the conversion process of desk and chair, during as desk and chair, lock and make its Stability Analysis of Structures reliable by alignment pin.

Detailed description of the invention

Fig. 1 is the schematic diagram of the utility model while using as desk, and Fig. 7 is in the utility model, to be the schematic diagram of a certain state in the process of chair by desk upset, and Fig. 4 is the schematic diagram of the utility model while using as chair.

Fig. 1 with in Fig. 4 except the position of positioner in support link 4 is different, other structure is symmetrical distribution.Positioner is on the connecting rod position of left support connecting rod 4 as depicted in figs. 1 and 2, and location key seat 7 is fixedly connected in support link 4 by rivet 10.Positioner is on the supporting leg position of right support connecting rod 4 as shown in Figure 4 and Figure 5, and location key seat 7 is fixedly connected in support link 4 by rivet 10.In Fig. 1, support link 4 lower ends are flexibly connected by heel pin 11 with the hole on base 1, and upper end is flexibly connected by panel pin 13 with the hole on panel 2; Ribbed insert 3 lower ends are flexibly connected by heel pin 12 with another hole on base 1, and upper end is flexibly connected by panel pin 14 with another hole on panel 2, and ribbed insert 3 and support link 4 are intersected.

The cross section of panel 2 is L shaped structure, and its outer upper surface can be used as desktop, and inner surface can be used as seat.

The desktop of panel 2 is parallel with base as shown in Figure 3, and the alignment pin 5 on left support connecting rod 4 inserts in the corresponding locating hole of ribbed insert 3.V-shaped structure in Fig. 4 on ribbed insert 3 uses as the handrail of seat both sides, and the alignment pin 5 in Fig. 5 on right support connecting rod 4 inserts in the corresponding locating hole of ribbed insert 3.The seat of panel 2 is parallel with base as shown in Figure 6, and the V-arrangement bracing frame bottom in support link 4 and base 1 bottom surface copline, play a supportive role.

In Figure 12, on the bar of alignment pin, have annular groove for mounting spring back-up ring 9.

Fig. 2 is the structure chart of positioner, in figure, location key seat 7 is bonded in support link 4 by rivet 10, on location key seat 7, have centre bore, packing alignment pin 5 into packs cylindrical spring into and check ring 9 is snapped in the annular groove on alignment pin, spring one end contacts with the inner surface of location key seat 7, the other end contacts with check ring 9, and spring is in compressive state.

When the utility model is changed between desk and chair, suppose the state now using as desk in Fig. 1.First pull the draw ring 6 on left support connecting rod 4 to make alignment pin 5 exit the locating hole on ribbed insert 3, then promote panel 2 and turn to Fig. 7 state, being rotated further panel 2 makes it turn to Fig. 4 state, now the alignment pin 5 on right support connecting rod 4 inserts in the locating hole on ribbed insert 3, completed the conversion to chair by desk, in whole process, panel has rotated 90 degree.
