Abstract

The utility model a size of top-adjustable table, belonging to the technical field of furniture design and production. A movable part of the table is composed of a movable table top, a movable table leg and a movable cross bar. The area ratio of a fixed table top and the movable table top is from 1: 0.5 to 1: 1. The fixed table top and the movable table top are connected by hinges. The table top of the utility model can be expanded by one time at most or can be diminished by one time at most. As the movable cross bar and the movable table leg are moved, the movable table top can be folded upwards or downwards to reduce the occupation space of the table.

Description

Size of top-adjustable table

The utility model relates to a kind of desk of regulating the desktop size, belongs to furniture design and manufacturing technology field.

Dining table is the requisite daily necessities of each family, general three-person household dining table area 0.5-0.6m ²Get final product, when the people had a dinner more, desktop amassed 1-1.2m ²Comparatively suitable.Existing desk is a kind of to be square table, the folding part of four sidebands, and it is circular turning up the back desktop, table leg is fixed, desk not the time spent desktop can be converted into the setting shape, the desktop foldable portion area of this desk only is 1/3rd of the gross area, fixedly square table part will occupy indoor nearly 1m ²Area, and the table four jiaos of wedge angle positions that are folded down children are damaged; In addition, its down the folding part branch be with spring assembly control, grown spring force service time and weakened or damages, turning up part can not maintain an equal level (staying) with square table, then loses the function of expansion usable floor area.

The utility model provides a kind of desk of new type of adjustable joint desktop size in order to remedy the deficiencies in the prior art, can be made as required to enlarge desktop 0.5-1 folding table doubly.

Structure of the present utility model mainly comprises following a few part:

One. desktop, can justify can just also rectangular or oblong.Desktop is divided into two parts, and the one, standing part, second half is a foldable portion, standing part is 1 with foldable portion area ratio: 1-1: 0.5.Fixedly be connected through the hinge between desktop and active desktop.Desktop is generally manufactured with timber.

Two. scalable part is formed in activity stull under the desktop and fixedly stull (sleeve pipe), and the activity stull is metal material preferably.Fixedly stull (sleeve pipe) peripheral hardware is attachment means such as female and jackscrew handwheel just like Luo, so that with activity stull and fixedly stull (sleeve pipe) locking.

Three. table leg, per two is one group, one group for movably, is connected with above-mentioned activity stull respectively, and fastens with active desktop; Another group for fixing table leg respectively with said fixing stull (sleeve pipe), fixedly desktop links to each other.Can add stull between every group fixes.

Also can make the fixing table frame of four legs, other establishes two movable table legs, and the time spent does not push under the table dormant frame.Two movable leg can link to each other with two activity stulls respectively, said fixing stull (sleeve pipe) is changed into fixedly making a call to two trepannings in the stull between the table leg 10.Also can in the middle of desk, establish a secondary activity stull and fixedly stull (sleeve pipe), as Fig. 8, shown in Figure 9.

Each part mentioned above is except that special requirement, and all available timber or metal pipe material are manufactured.Dimensions is decided as required.The movable part of desk is formed in above-mentioned active desktop, movable table leg, activity stull, and all the other are standing part.Above-mentioned active desktop, fixedly the connected mode of desktop and hinge can have following several:

1. symmetry flushes down the folding formula, and the hinge axle center is arranged in the below at two desktop interface places, and as shown in Figure 1, the folding maximum is 90 ° under the active desktop, shows as Fig. 2, can lean on wall and puts.

2. folding formula on the vertical joint, hinge is perpendicular to place two desktop interface places, and as shown in Figure 3, active desktop can upwards be turned up 0-180 °.During 90 ° of last foldings, show that as Fig. 4 can lean on metope and put, beautiful desktop can play certain decoration function; 180 ° of last foldings, active desktop are overlapped in fixedly on the desktop, show as Fig. 5.

3. the eccentric folding formula down that connects, hinge axle center are positioned at fixedly desktop and active desktop interface inboard (the eccentric connection), equal desktop thickness with the interface distance.Show as Fig. 6.Following folding shows as Fig. 7 for maximum 90 °.This folding mode makes desk account for minimum space to greatest extent.

Below in conjunction with description of drawings the utility model is further described.

Fig. 1. structural representation of the present utility model (side-looking).Wherein, 1. movable table leg, 2. active desktop, 3. hinge, 4. mother Luo, 5. jackscrew handwheel, 6. fixing desktop, 7. fixing table leg, 8. fixedly stull (sleeve pipe), 9. activity stull.
