Abstract

The utility model relates to a folding copying and reading bookshelf which belongs to a stationary article. When people read or copy books, the books are held by both hands for reading or one hand presses the books and the other hand holds a pen for copying, which is troublesome. Arms are easy to be tired and sitting postures are not correct. Because the heights of a table and a stool are not comfortable, (particularly pupils) myopia and strabismus can be caused. An attached figure can be referred. The utility model comprises movable bracket boards (4) which can be folded in a main frame (1), a folding bracket board (3), a telescopic support board (5) and the pull board (6) of the support board. The distance among the movable bracket boards (4) and the inclination angles of the folding copying and reading bookshelf can be adjusted freely by lateral-spacing positioning card members (4 to 1) and the telescopic support board (5). The utility model has the advantages of light weight, small folding size, easy portability, simple structure and convenient use.

Description

Folding reading and writing-rack

The utility model belongs to stationery.

People or hold book in hands and read when reading or copying books; Or a hand book, take pen to copy on the other hand, trouble not only, and cause arm fatigue easily, and abnormal sitting posture, because table stool height is uncomfortable, (particularly pupil), the visual angle is too small, can cause and copy reader's stravismus or myopia.

The purpose of this utility model provides a kind ofly can improve the visual angle, and correcting sitting postures reduces the requirement of copying trouble when readding.

The purpose of this utility model is achieved in that books is pressed on the shelf that can amount to and launch, the both sides that books separate are with pressing card to be pressed on the supporting plate of horizontal roll adjustment, according to the retractable supports plate behind the sitting height adjusting shelf of copying the person of readding, to realize optimal viewing angle.

Below in conjunction with accompanying drawing a kind of example of the present utility model is described in detail.

Fig. 1 is a structure chart of the present utility model.

Fig. 2 is " body frame " of the present utility model structure chart.

Fig. 3 is " mobile pallet " of the present utility model structure chart.

Fig. 4 is " retractable supports plate " of the present utility model structure chart.

With reference to Fig. 1, Fig. 2, Fig. 3: this can be by iron plate, and timber, polyethylene are made.But from processing difficulty or ease, requirement of strength, factors such as weight change worry, are that material is comparatively suitable with the polyethylene.Body frame (1) is by body frame connecting plate (1-1), body frame top plate (1-3), body frame lower plywood (1-4), connecting plate holder (1-5), etc. composition, retractable supports plate Connection Block (1-6) and gripper shoe arm-tie Connection Block (1-7) are arranged on the body frame lower plywood (1-4), and two body frames (1) can be amounted to as hinge for the axle center by body frame connecting hole (1-2).There is connecting hole at connecting plate (2) two ends, and the available screw of an end is fixed on the connecting plate holder (1-5) of body frame (1), the other end can with amount to supporting plate (3) and be connected with rivet; Amounting to supporting plate (3) one ends has connecting hole, can be connected with connecting plate (2), and can connecting plate (2) and the tie point of amounting to supporting plate (3) be that the axle center is rotated 90 °, amounting on the supporting plate (3) has several concave indentation; Mobile pallet (4) two ends are rectangle frames, can be enclosed within and amount to supporting plate (3) and the last move left and right of connecting plate (2), wherein an end is equipped with horizontal spacing location fastener (4-1) and spring (4-2), horizontal spacing location fastener (4-1) can stretch out to insert under spring (4-2) effect laterally amounts to upward concave indentation of supporting plate (3), to realize mobile pallet (4) location, with the moving regracting of palm, realize mobile pallet (4) move left and right.Mobile pallet (4) can be along amounting to supporting plate (3), and connecting plate (2) is pushed in the interlayer of body frame top plate (1-3) and body frame lower plywood (1-4).The retractable supports plate Connection Block (1-6) that connects retractable supports plate (5) is arranged on the body frame lower plywood (1-4), can be connected retractable supports plate (5) on the body frame lower plywood (1-4) with pin, the gripper shoe arm-tie Connection Block (1-7) that connects gripper shoe arm-tie (6) is arranged on the body frame lower plywood (1-4), can be connected gripper shoe arm-tie (6) on the body frame lower plywood (1-4) with pin, there is concave indentation gripper shoe arm-tie (6) termination, can be connected with retractable supports plate (5), retractable supports plate (5) and gripper shoe arm-tie (6) can pin be that the axle center rotation is folded on the body frame lower plywood (1-4).

With reference to Fig. 4: the structure of retractable supports plate is: available pin and body frame lower plywood (1-4) are gone up fixed head (5-1) that retractable supports plate Connection Block (1-6) is connected, are contained in movable platen (5-2), inclination angle positioning cards (5-3), pressure handle (5-5), pressure handle spring compositions such as (5-4) in the fixed head (5-1).Several locating slots (5-7) are arranged on the fixed head (5-1), and movable platen (5-2) bottom has one to be used for " worker " shape connecting hole (5-6) of being connected with gripper shoe arm-tie (6).When needs are adjusted the shelf inclination angle, (5-5) depresses with pressure handle, inclination angle positioning cards (5-3) is lifted, pulling movable platen (5-2), choose suitable locating slot (5-7), unclamp pressure handle (5-5), spring (5-4) pressure handle (5-5) of upspringing, the inclination angle positioning cards fall into locating slot (5-7) fixedly movable platen (5-2) realize the location, inclination angle.

Use concrete operations: this is placed on the plane, body frame (1) is launched, screw out from the interior connecting plate of body frame (1) (2) amounting to supporting plate (3), mobile pallet (4) is interior along connecting plate (2) from the interlayer of body frame top plate (1-3) and lower plywood (1-4), amounting to supporting plate (3) is pulled to and amounts to supporting plate (3) outer end, then with gripper shoe arm-tie (6) from body frame lower plywood (1-4)) extrude, retractable supports plate (5) is extruded from body frame lower plywood (1-4), by " worker " shape connecting hole on the movable platen (5-2) of retractable supports plate (5) retractable supports plate (5) is connected with gripper shoe arm-tie (6), will copy the books of readding and translate into content, the book back is placed between two body frames (1), the both sides that books separate are with pressing card (4-3)) push down, according to sitting by and watch Height Adjustment retractable supports plate (5), copy or read again to desirable visual angle.

Because the present invention has adopted collapsible combination, manufacture material and be advisable with polyethylene, thus in light weight, and can be modulated into the people that various colors are suitable for different personality and age, two kinds of developed surface integration A type and Type Bs, A type developed area; Long 200mm * wide 280mm; Type B developed area: long 270mm * wide 380mm, folding back A type volume: long 200mm * wide 75mm * high 30mm; Folding back Type B volume: long 270mm * wide 75mm * high 35mm has solved and has copied the bookshelf Heavy Weight in the market applicable to the books of all thickness of 16-64 format, and volume is big, can not fold, and carries inconvenient problem.
