Description

A bookshelf with reading tables and chairs

technical field

The utility model relates to a bookshelf for a library, in particular to a bookshelf with foldable reading tables and chairs.

Background technique

At present, some libraries have a relatively concentrated flow of people. There is a shortage of reading seats on Saturdays and Sundays, and the flow of people on weekdays is relatively small. The management mode of libraries is mostly an integration of collection, borrowing, and reading. Increasing the number of reading seats will occupy the collection space, and the vacancy on weekdays will increase the waste of resources.

Some bookshelves are far away from the reading seats. When readers need to browse books, take notes or take pictures for a short time, they need to walk back and forth between the bookshelves and the reading seats, which is inconvenient and affects others.

In response to the above problems, some libraries place low stools on one or both sides of the bookshelves for readers to use. The low stool takes up space when not in use, and there is no place for readers to put books when they are taking notes or taking pictures.

Utility model content

In order to overcome the above defects, the utility model provides a bookshelf with folding tables and chairs, which can be used as temporary reading seats, which is convenient for readers to write and take pictures, and saves space.

The technical solution adopted by the utility model is: a bookshelf with reading tables and chairs, including the bookshelf body and foldable tables and chairs, and the foldable tables and chairs include table boards, table legs, chair seats and chair legs; when the table boards are horizontal for Shaped, the upper surface is flat, the lower surface is stepped, when folded, the lower surface can place table legs, one side of the table is connected to the side plate of the bookshelf body through a hydraulic hinge along the edge, and the other side of the table passes along the edge The hydraulic hinge is connected to one end of the table leg, and the table leg is shape, the rods on both sides of the table legs are stretched by using marbles, shrapnel and bullet holes; The middle part of the side bar is connected by a connecting shaft; one side of the chair surface is connected to the side of the chair leg by a hydraulic hinge, and the chair leg is a cuboid.

The hydraulic hinges are hinges with mature elastic reset and hydraulic damping functions, and different specifications and sizes are used at different connection positions. The hydraulic hinges can be positioned by positioning beads at 90°, and can be Self-closing.

The beneficial effects of the utility model are: by setting foldable reading tables and chairs on the side of the bookshelf, when the reading seats are in short supply or reading for a short time, the tables and chairs can be opened as temporary reading seats; when readers take notes or take pictures, they can be opened separately The table; the table and chair are simple in structure, have a positioning function when opened, and are convenient to use.

The seat is reversibly connected to the table body through the connecting shaft, and the table body is reversibly connected to the side panel of the bookshelf through the hinge. When folded, it has an automatic storage function. After folding, the table and chair structure is stored in the seat surface. It is convenient and fast, saves space, and does not affect the cleanliness and beauty of the library environment.

detailed description

The bookshelf with folding tables and chairs involved in the utility model is proposed to solve the shortage of reading seats in the library during the peak period of people flow, the reading seats are far away from some bookshelves, and when readers need to take notes or take pictures, there is no desk nearby for support. Its structure is shown in Figure 1.

A bookshelf with folding tables and chairs, which includes a bookshelf body 1, a table board 2, table legs 3, a chair seat 4 and chair legs 5, one side of the table board 2 is connected to the bookshelf through two hydraulic hinges 6 The side plate 11 of the main body 1 is connected, and the hydraulic hinge 6 is installed at both ends of the lower plane side of the table. The page 6 is automatically positioned, the end surface of one side of the table board 2 and the side board 11 are attached to each other, and the table board 2 is fixed.

The other side of the table board 2 is connected to one end of the table leg 3 along the edge by two hydraulic hinges 6, and the hydraulic hinges 6 are installed on the two ends of the other side of the lower plane of the table board 2. When unfolded The table board 2 and the table leg 3 form a 90° angle, and the hydraulic hinge 6 is automatically positioned; The table top 2 and the table legs 3 are relatively fixed, and the table legs 3 support the table top 2 .

The table leg 3 is a telescopic mechanism, including a telescopic outer rod 31 and a telescopic inner rod 32. The telescopic operation of the telescopic outer rod 31 and the telescopic inner rod 32 adopts mature technology such as card holes, pinholes, shrapnel and marbles. The telescopic mechanism 8 constituted, when the table needs to be unfolded, the marbles are pressed to extend the table legs 3, and when folded, the marbles are pressed to shorten the legs 3; the telescopic inner rod 32 is a hollow cuboid, The telescopic outer rod 31 is integrally formed by a solid upper rod and hollow two-side rods.

The connecting rod 41 of the seat base 4 is connected with the middle part of the side bar of the chair leg 3 through the connecting shaft mechanism 7, and the connecting shaft of the connecting shaft mechanism 7 is in clearance fit with the seat base 4 and the chair leg 3, and the connecting shaft There are threads at both ends of the seat, which are connected with nuts. When the seat 4 needs to be unfolded or folded, the nuts are loosened so that the seat 4 can rotate around the axis. When the seat 4 is in the unfolded or folded state , tighten the nut to secure it. The seat 4 is integrally formed by two connecting rods 41 and a seat surface 42 , the two connecting rods 41 form a space for accommodating both legs, and the chair surface 42 is used for readers to sit on.

One side of the chair leg 5 is connected to the side of the seat 4 along the edge through two hydraulic hinges 6, and the hydraulic hinge 6 is installed at both ends of the lower surface of the seat 4. The legs 5 are cuboids, and in the unfolded state, the seat 4 and the legs 5 are at 90°, the hydraulic hinge 6 is automatically positioned, one side of the legs 5 touches the ground, and the legs 5 The other side is attached to the lower surface of the seat 4 , and the legs 5 are relatively fixed to the seat 4 , and the legs 5 support the seat 4 .

When the reader only needs the table to temporarily take notes or take pictures, the seat 4 is in close contact with the chair leg 5 under the elastic recovery of the two hydraulic hinges 6 along one side of the chair leg 5 . The seat 4 is fixed between the side bars of the table legs 3 by the connecting shaft and the nut of the connecting mechanism 7, as shown in FIG. 2 .

When the table and chair need to be folded after use, press the positioning beads of the two hydraulic hinges 6 on one side of the chair leg 5 to rotate the chair leg 5 toward the seat 4, and the angle between the two When it is less than 90°, the chair legs 5 are automatically closed until they are attached to the seat seat 4; the nuts of the connecting shaft mechanism 7 are loosened, and under the action of gravity, the seat 4 and the chair legs 5 work together Rotate around the axis until it is vertical to the ground, between the telescopic inner rods 32 of the chair legs 3, tighten the nuts, and the seat 4 is fixed on the table legs 3; press the marble on the telescopic mechanism 8 to make The chair legs 3 are shortened; press the positioning beads of the two hydraulic hinges 6 at one end of the table legs 3 to rotate the table legs 3 toward the table board 2, and when the angle between the two is less than 90° , the table legs 3 are automatically closed until they are attached to the lower surface of the table board 2; press the positioning beads of the two hydraulic hinges 6 on one side of the table board 2 to move the table board 2 to the The direction of the bookshelf side panel 11 rotates, and when the angle between the two is less than 90°, the table panel 2 with the chair legs 5, chair seat 4, and table legs 3 folded is automatically closed, and the elastic force of the hydraulic hinge recovers. Under the effect of gravity and the folding table and chair, the folding table and chair are close to the side plate 11 of the bookshelf body, as shown in FIG. 3 .
