Description

Square dinner table capable of lifting and falling with central rotary round plate

The present invention relates to a kind of dining table, is the central rotating disk Liftable type dining table of a kind of side's band circle.

At present, the lazy Susan generally used of people is made up of a roundlet desktop that can rotate and a big detachable round tabletop that is positioned at its below.The weak point of this kind dining table is: the roundlet desktop that can rotate is to be put into separately on the big detachable round tabletop, has a dinner after the end, will take off from big detachable round tabletop toward contact, and is very inconvenient.Afterwards the someone designed " rotating dining table automatically " China Patent No. 86200175 and " electronic lazy Susan " China Patent No. 86202435 the former can control automatically stop, change, without hand push, elegant, steadily, mounting or dismounting simultaneously are convenient, the saving raw material.The latter is except the advantage that the former had, and central rotating disk can also lifting, and big detachable round tabletop is changeable etc.Changed the weak point of the lazy Susan of generally using at present.But the structure of these two kinds of dining tables is more complicated all, and cost is just high naturally.According to the purchasing power of at present general family, then more need not only convenient, suitable but also cheap and good-quality dining table.The lifting of " electronic lazy Susan " central rotating disk is a kind of relative lifting with respect to big detachable round tabletop, changes it with respect to the height of central rotating disk and be actually by the big detachable round tabletop of lifting.The novelty and the creativeness of this " the central rotating disk Liftable type dining table of side's band circle " are: height of table top is constant, central rotating disk alterable height, and also the change of rotating disk height is to realize by the lifting skewback under the pallet.Traditional side's band circle dining table can change the size of desktop easily, and the present invention puts together this advantage again, forms a novel and practicable and dining table simple in structure.

The objective of the invention is to be square table for general family provides the people that has a dinner, the people that has a dinner is round table for a long time, and central rotating disk liftable after a little while, and it is novel, simple in structure to be suitable for, cheap and good-quality novel dining table.

Content of the present invention: dining table involved in the present invention is made up of following major part shown in Figure of description: rotating disk (1), the big bearing in plane (2), pallet (3), lifting skewback (4), square table face (5), table leg (6), crescent are hung limit (7) and bridge-type spring hinge (8).The bottom of the big bearing in top and plane (2) of pallet (3) is fixed together by securing member, following and the lifting skewback (4) of pallet (3) is fixed together by securing member, when with hand under desktop during Rotary tray, the lifting skewback that is fixed together with pallet also rotates with pallet, owing to below the lifting skewback inclined-plane is arranged, when the inclined-plane just can drive pallet (3) one lifting during along the last planar slide of board-like table leg.Rotating disk this moment (1) is lifting simultaneously also.The leg of dining table can also be designed to traditional square leg or circle leg, and loads onto crossbeam (in the accompanying drawing, crossbeam and board-like leg become one) in the diagonal of four legs (other directions also can), so that the supporting elevation skewback.There is limited block in the outside that the lifting skewback leaves center of circle direction, and axial location immobilized when (limited block and board-like leg become one in the accompanying drawing) rotated with the assurance pallet.

Below specific embodiments of the present invention is illustrated with accompanying drawing:

Fig. 1 is the front view of dining table.Among Fig. 1, rotating disk (1) is fixed together with securing member (for example wood screw, tapping screw) with the last plane of the big bearing in plane (2), and the pivot center of bearing should coincide with the geometrical axis of rotating disk.The lower plane and the pallet of bearing are fixed together with securing member.The vertical view of pallet is circular, and the geometrical axis of pallet should coincide with the pivot center of bearing.Should make three to six screws on the lower plane of bearing, make corresponding unthreaded hole on the pallet.Screw is screwed into screw during installation after the unthreaded hole under the pallet penetrates.Just the lower plane of pallet (3) with bearing (2) can be fixed together.The last plane of the big bearing in plane is a moving-coil, and lower plane is fixed circle.Moving-coil and fixed circle often are stamping parts, between moving-coil and the fixed circle steel ball are housed, and have on the moving-coil and wear the unthreaded hole that securing member is used.To enclose surely again and make screw and just can use.If do not make screw on the fixed circle, also can adopt another program, this scheme is to load onto center bridge on the last plane with pallet, and center bridge blocks decides circle endoporus or cylindrical, and center bridge is just for the pivot center of bearing firmly surely, and do not influence the displacement of bearing along axis direction.This kind scheme can take off or be put into pallet by accurate position from pallet with bearing fixing rotating disk together at any time.The height of center bridge must be less than the thickness of bearing, as long as the coil axis of deciding of bearing is fixed, center bridge can be designed to difformity and quantity.For example: can be circle during fastening circle endoporus, bikini or four-point, the outer bowlder of fastening circle can be circular ring type, bikini or four-point.Be lifting skewback (4) below the pallet (3), the shape of lifting skewback as shown in Figure 3 and Figure 4.The lifting skewback is that the identical several wooden units of shape are made, vertical view after several lifting skewbacks connect from beginning to end is an annular, the lower surface of lifting skewback has an inclined-plane along the vertical lifting, the head on inclined-plane and tail respectively have the anchor ring of a level, two anchor rings respectively are the supporting surface of pallet when the highest or extreme lower position, the upper surface of lifting skewback is a horizontal ring plain, it be attached to pallet below.Pallet and lifting skewback are fixed together with securing member, and the axis that the lifting skewback surrounds the cylindrical after the ring-type should coincide with the axis of pallet.Lifting skewback and pallet are cores of the present invention.Below the lifting skewback crossbeam is housed, the quantity of crossbeam equates with the lifting skewback, its position and lifting skewback coupling, and its effect is to match in order to lifting tray with the lifting inclined-plane, and supports weight such as pallet, rotating disk.Crossbeam can be made on the diagonal that one (as shown in Figure 1) also can be installed in four legs of ordinary table or on other directions with board-like table leg.The lifting skewback leaves the outside of center of circle direction, and axial location immobilized when limited block (limited block and board-like leg become one in the accompanying drawing) was housed with the rotation of assurance pallet, and limited block is contained on the crossbeam, or is contained on the member of supporting traverse.Crescent is hung limit (7) and connected with the bridge-type spring hinge with square table face (5), and also available butterfly hinge or ready-made hinge connect, and the benefit that connects with the bridge-type spring hinge is: it can vertically be affixed under the square desktop when put down on the limit when crescent is hung, so better appearance.

The advantage that the present invention compared with prior art has is: existing dining table is that square circular or square band is circular, and as using rotating disk, rotating disk is to be put into separately on the dining table, has a dinner after the end, takes off from desktop again, and is not enough convenient. " automatic spinning dining-table " and " Hotor-driven rotary dinning table " though be that function ratio is more complete, complex structure, cost height. Dining table involved in the present invention has overcome the weak point to put on the dining table, not only convenient be suitable for but also good and cheap. When the people that has a dinner is many, rises crescent extension limit and just can increase the dining table area. It is lower that hand is reached table, and to a direction Rotary tray, rotating disk just stretches out desktop, have a dinner finish after, counter-rotation pallet again, rotating disk just drops to and the desktop sustained height, and is easy to use, do not need the place of putting rotating disk by discharging in addition.
