Description

Lifting revolving multipurpose dining table

The present invention relates to the lifting revolving multipurpose dining table of having dinner and use in a kind of family and restaurant.

Lazy Susan of the prior art, the lazy Susan as Chinese patent application 86210489,87205523 proposes all can solve " far " apart from the difficult problem of picking up food with chopsticks.But because flap is around fixed axis rotation, can not lifting, thereby big garden desktop becomes changeless stairstepping with flap, limited the result of use of desk.

For addressing this problem, common way is to rely on flap middle part rotating shaft to carry out lifting and rotation, as Chinese patent application 88221565.5 described elevating methods, very reaches the lifting purpose simply and effectively.But, implement certain difficulty for dining table.If it is loosening that the fit clearance between axle and the axle sleeve has slightly,, influenced the quality of rotating just waving appears in flap.

The objective of the invention is to provide a kind of new lifting revolving multipurpose dining table, it not only can make, and flap is rapid to rise or descends (rotating with the stable flap that holding in the palm of bigger breadth when flap rises), and can do common plane dining table or chafing dinning table use.

Invention is achieved in that the driving lever that at least three one end band pawl other end bands commentaries on classics tools is housed being fixed on the carriage of annular slab, and angle of rotating lever claw can be put the extreme higher position with changeing tool, and flap is held up, and the supporting flap rotates.Be placed with in the seat of chamber offer centre bore and with the shifting block of driving lever claw correspondence position bayonet socket, the driving lever claw puts in the corresponding bayonet socket, the rotating shaft of being fixed in flap inserts in the centre bore of shifting block.Striking gear connects (or button) and is connected on the shifting block.Promote the handle of striking gear, shifting block is rotated an angle, bayonet socket is stirred the driving lever claw angle simultaneously, changes tool flap is held up, and flap is pressing the commentaries on classics tool for arbitrarily rotating.When thereby flap is fallen in handle drives shifting block revolution, the position that striking gear can fixed rotating shaft, in case foot rest when folding flap deviate from.

The concrete structure of invention is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the structure chart of the lifting revolving multipurpose dining table that proposes of the present invention, and the handle of its striking gear is contained in the top of carriage.

Fig. 2 is the vertical view of driving lever, handle and shifting block rigging position.

Fig. 3 is a handle locator card structure chart.

As Fig. 1, Fig. 2, shown in Figure 3, annular slab [1] is all fastening each other with carriage [2], chamber seat [6] and carriage [2], flap [3] and rotating shaft [8].Carriage is provided with three and divides equally the driving lever [4] that changes tool [4a] in end band pawl [4b] other end band in garden week, and is solid on carriage driving lever with card sign indicating number [5].Be placed with in the chamber seat [6] offer centre bore [18] and with the shifting block [7] of driving lever claw correspondence position bayonet socket [16], the driving lever claw puts in the corresponding bayonet socket, rotating shaft [8] inserts in the centre bore [18] at shifting block.

Striking gear is the handle [14] of "T"-shaped band handle pawl [9] and locator card [12] etc. by the left side and forms.Card sign indicating number [11] and locator card [12] are firmly solid at carriage [2] and annular slab [1] up knob handle [14] respectively.At this moment, have additional and the corresponding upwards folder of the handle pawl [9] of handle mouthful [17] bottom that folder mouth snapping the handle pawl at shifting block [7].Rotating shaft [8] has additional annular mouth, and when falling for flap, the pin head [10] of handle [14] inserts just, and rotating shaft position is fixed.

The program of rising flap is: the draw-out handle of turning right [14], pin head [10] breaks away from annular mouth.[14] angles of turning handle, handle pawl [9] promotes shifting block by corresponding shifting block folder mouthful [17] and rotates an angle.Three bayonet sockets of shifting block are stirred three driving lever claws simultaneously and are put the highest position changeing tool [4a], commentaries on classics tool three summits are formed a bundle of planes flap [3] and are held, the pushing handle [14] of turning left then, little pin [13] (see figure 3) of handle is stuck in the notch [19a] of locator card [12], thereby handle pawl [9] has been fixed shifting block [7].At this moment, pin head [10] still is in disengaged position with the annular mouth of rotating shaft.Flap [3] is pressing commentaries on classics tool [4a] to supply rotation arbitrarily around rotating shaft [8].Flap also can arbitrarily split out, and is convenient to inner the cleaning.

Falling the flap program is: the handle of turning right [14], and the little pin [13] and the notch [19a] of locator card are broken away from, rotary handle [14] turns round shifting block [7] simultaneously, thereby falls flap [3].At last, the pushing handle of turning left [14] injects in the annular mouth of rotating shaft pin head [10], and rotating shaft is fixed.At the same time, little pin [13] just in time is stuck in the notch [19b].

Described locator card [12] also can be installed on the carriage of flap below along the handle shaft.

The available roller of described commentaries on classics tool [4a] also can connect the turning collar (not shown) that use in a common restaurant at the roller top of three driving levers in week such as the garden of grade, it is more level and smooth that flap is rotated.

[15] among the figure are foot rest.

Fig. 4 is that another kind of striking gear is implemented structure chart.

Fig. 5 is the schematic diagram of this structure chart lumen seat translot.

This striking gear by the band pin rod handle [14], packing ring [21a], spring [22], packing ring [21b], latch [20] and set up the translot [27] at chamber seat [6] downside, the hole, garden [25] of shifting block [7] downside, the annular mouth [24] of rotating shaft [8] bottom etc. and form.The two ends of translot [27] are bored aperture [26] and [a 28] (see figure 5) bigger slightly than translot mouth bore respectively, and the flange [23] of handle [14] just is inserted in.

The size of said structure should be accomplished: one, move left and right is freely in hole, shifting block garden [25] for handle pin rod and the packing ring [21a] that is inserted in, spring [22], packing ring elasticity sub-assemblies such as [21b]; Two, the length of chamber seat translot [27] should make driving lever change tool [4a] with rotary handle [14] to put when the highest, and the position at handle place is as the criterion.

Shown in Figure 4 is when flap falls, and the handle pin rod is being pressed the state of annular mouth [24] bottom.At this moment, the flange [23] of handle [14] is inserted in the aperture [26] of chamber seat translot left end, has kept the fixing of rotating shaft [8].

When needing rising flap [3], then turn right and spur handle [14], make the handle pin rod break away from the annular mouth [24] of rotating shaft, the flange of handle breaks away from chamber seat translot aperture [26] simultaneously, then, driving handle makes pin rod move along translot [27], during to other end aperture [28] flange is plugged, thereby has been fixed shifting block [7].This process, the packing ring [21a], packing ring [21b] and the spring [22] that are connected in shifting block aperture [25] promote shifting block [7] and rotate, and the shifting block bayonet socket promotes driving lever commentaries on classics tool and rises to the extreme higher position.

Part shown in all the other among the figure, [1] is annular slab, and [2] are carriage, and [4] are driving lever, and [5] are the card sign indicating number, and [4b] is pusher dog, and [15] are foot rest.

When falling flap, the 3rd embodiment of fixed rotating shaft is that rotating shaft is extended, and allows rotating shaft pass the chamber seat, fixes with pin then.

After falling flap, annular slab becomes a plane with flap, can work as conventional tables and use.This dining table also can be folding with foot rest.

Take away behind the flap, can make hot pot table usefulness, place tables central recess (be shifting block hole in) with micro-wave oven or charcoal stove this moment, allows a little higher than table top of chafing dish, as shown in Figure 6.

If chamber seat, shifting block, the rotating shaft equidimension is corresponding dwindles, then only make lazy Susan and common plane dining table and use.

The plate face portion of this dining table can adopt board-like making, and also the press moulding mode that annular slab and carriage can be fused is made.
