Description

Multi-purpose foldable combined table and seat

The utility model relates to a kind of chair desk of multipurpose collapsible.

Recently, occurred number of patent application on the market and be 91222898.9 and can regulate the chair desk of tables and chairs face height and angle, the sitting posture when this chair desk can be corrected people's work and study, and have and take up an area of few advantage.But this chair desk often is confined to four rod member supporting structures, inconvenience when this structure folds and decontrols, and the parts of four rod members are many, it is not compact to take material and structure, it is unstable that integral body seems, can not adjust sighting distance visual angle, especially four rod member supports simultaneously at random and launch the space that back continuous table, chair leg have limited leg movements when the people sits down, the pin that makes the people easily and support collide with, standing, it is all very inconvenient to sit down.

The purpose of this utility model just is to propose a kind of advantage that can keep prior art: collapsible, health-care effect is arranged; Can remedy the deficiencies in the prior art: increase the activity space of people's leg, it is convenient to shrink, and compact conformation can be adjusted the sighting distance visual angle, the chair desk of one-object-many-purposes simultaneously.

The technical solution of the utility model is achieved in that in the chair desk both sides a kind of symmetrical three rod member supports is set that wherein every rod member can be made single, also can be made into cover rod-type more piece part extending and shortening.All rod members all are linked to be integral body by linkage.Chair leg and table leg all are curved bars, and curved bar has one section support that lands.The chair leg the angle of location rod member and the continuous non-segment length's of landing straight-bar spare bending between 40 °-90 °, and table leg the location rod member and linked to each other the non-long straight-bar spare of end that lands between 80 °-120 °.Connecting a table leg auxiliary bar by the linkage that can carry out angle adjustment between 0 °-90 ° on the table leg, support lands.This situation just constitutes three rod member supports.Table leg and chair leg the location rod member and are linked to each other by the linkage that can carry out angular adjustment between 10 °-180 °, and when hinge during at 10 °-20 °, these two sections parallel coincidences of bent stick can be folded up; When hinge during at 180 °, two curved bars are in alignment, and supporting lands, and constitutes chair desk and supports.The upper end of table leg is connected with the adjustment plate by manual locking device, adjusts on the plate desktop is housed.Adjusting plate has the slotted eye of two kinds of tracks, and a kind of is the straight line slotted eye, and its length is 100-200mm, and desktop is coupled by locking device, and a kind of is arc groove, and radian links to each other with table leg by locking device for being 0 °-180 ° of benchmark to be parallel to desktop.Be connected with the desktop connected mode by table leg by the adjustable plate that has only arc groove between chair leg and the seat support.Kneepad is set between table leg, uses hard material in the kneepad, the external application soft material constitutes, and its lateral surface is a semicircle, also can be circular or square.Disjunctor support phase spacing is 320mm-460mm, table leg link to each other with the chair leg the length 250-370mm of location curved bar when being in line, chair cushion surface middle point vertical height is 400-500mm, table-top surface middle point vertical height is that 680-780mm desktop and pad face midtread distance are 380-540mm, kneepad peak vertical height is 300-420mm, and horizontal range is 240-400mm between the chair cushion table plane mid point and the kneepad semicircle center of circle.

Compared with prior art, especially compare with the chair desk of four rod members symmetry disjunctor support, the utility model not only keeps collapsible, the adjustable angle of four rod members, the advantage of one-object-many-purposes, also have the following advantages: compact conformation, materials are economized, and entire bracket is linked to be integral body, does not have protrusion, there is not barrier between the tables and chairs, the space is big, and turnover and sitting are convenient, create an aesthetic feeling; The straight-line groove of adjusting on the plate can make desktop move forward and backward, and arc groove can make desktop, seat angle obtain adjusting, and can adjust sighting distance and visual angle simultaneously like this, makes chair desk more convenient and suitable; Because what support landed is two sections straight lines, thereby support is more stable; Because be provided with kneepad, thereby stern when the people is sat down, knee can be simultaneously stressed, alleviated the concentrated stressed of certain position of human body, moreover the chair cushion suitable angle that can tilt, and makes people's waist bar straight and upright naturally, played certain function of health care.Chair desk can be done arm-chair usefulness when the desktop accent heavily is tending towards vertical ground, when packing up chair cushion chair leg, can do square table usefulness when desktop is set level, and adjust the desktop angle and also can make drawing board this moment.Reached the purpose of one-object-many-purposes so again.

Below in conjunction with accompanying drawing the utility model is done and to be illustrated further.

Accompanying drawing is the single rod member disjunctor of a kind of three rod members of a utility model support embodiment schematic diagram.

Fig. 1 is a working state schematic representation, and Fig. 2 is a duty side diagrammatic sketch, and Fig. 3 is the folded state schematic diagram, Fig. 4 for connect two sections location rod member linkage installation diagram, Fig. 5 is the kneepad installation diagram.

Desktop 1 is adjusted plate 3 by desktop and is connected with table leg 5.Adjust the plate straight-line groove and link to each other with desktop 1 by fastening bolt nut 2, arc groove is connected with table leg 5 by fastening bolt nut 4.Table leg 5 can be connected by the hinge or the rotation iron clad 6 of adjusting angle in 0 °-50 ° with table leg support 7, the curved bar of table leg 5 location and the location by being connected by the linkage 9 of adjusting angle with chair leg 10 curved bars in 0 °-180 °, and chair leg 10 upper ends link to each other with chair cushion 13 by the adjustable plate 11 usefulness fastening bolt nuts 12 that have arc groove.

Chair leg,

table leg

5,7,9 connect to form two symmetrical three rod member support A, B by linkage and adjustment plate.Between the A of table leg, B support turning cylinder or bolt 14 are set, kneepad 15 is placed on the turning cylinder 14.The kneepad side is semi-circular, is semicircle near human knee's face, is made of soft material, and straight plane is the hard liner plate.The back shaft 18 that one support kneepad is arranged under the turning cylinder.

What Fig. 4 reflected is the installation diagram of linkage 9.Connect iron 20 and be linked to be integral body with 5,10 by the turning cylinder 19 that constitutes by bolt and nut on 5,10.16 for spring draws pin, and 17 is pin-and-hole, draws pin to insert when not folding and draws pin-and-hole, when folding, draw pin to transfer to and draws pin-and-hole.
