Abstract

The utility model relates to the improved structure of an easy chair. A joint which makes a rack body pivoted across is provided with a pivoting block of which the two opposite sides form grooves. Both ends of the pivoting block are reversely inclined outwards and form an inserted rod with a ring channel. If the pivot connecting block is unfolded, the oppositely jointing step surfaces of the grooves are bunted and supported each other, so the shearing force of a pivoted rivet is reduced. Because of the ring channel of the inserted rod, a sheathed pipe body can directly cause the wall of the pipe to be concave and be inserted into the ring channel in the pressing mode opposite to the ring channel to fix the wall of the pipe. A C-shaped buckling ring and a sleeve barrel are arranged at the end of a horizontal supporting pipe at chair face cloth, and the sheathed pipe can be inserted and fixed or compressed inwards to cause the horizontal supporting pipe to be disassembled. The chair face cloth can be taken out, washed and replaced.

Description

Improved structure of easy chair

The utility model relates to a kind of leisure chaise longue.

All kinds of seats of present market, its form is numerous, the grace of emphasizing moulding that has, have with meet ergonomics, comfortable be the demand emphasis, favor with functional attraction consumer is then arranged in addition, be ever-changing, make us order and be too busy, made earnest efforts and wherein pursue in recent years to human because of the outdoor leisure motion, can have a rest everywhere when being engaged in the outdoor leisure motion for making, be the leisure chaise longue that develops multiple simple type, its main characteristics is all collapsible, is beneficial to carry carrying.

And the simple type leisure chaise longue of general portable, it mainly is that to intersect the jaw type support body with one be bracing frame, noose one chair cloth it on, and extension one chair back on support body one side direction in addition reaches by the jaw type support body and to cause a collapsible effect; Wherein, as shown in Figure 8, its design that intersects pivot knot joint is directly (B) staggered with two bodys (A), connect and utilize a rivet (C) to wear the knot pivot, if and it is with two kinds of unlike material winding persons, its body (A) is with concentric reducer mode insert group (B), and again in connection terminal mat rivet (D) rivet clasp in addition, so, the support body of this staggered form is opened vertically-arranged when it and is sat when having a rest for the people, body (A) pivot knot rivet (C) (B) bears human weight, be subjected to a shearing action, easily be twisted and cut off, service life is short; In addition, be with closing-up between each pipe fitting because of support body, chair cloth is once be inserted in the support body combination and finish, chair cloth promptly can't be pulled down to give cleaning, with the passing of time then shows intolerably dirty, damages also to be difficult to change, again, its body (A) (B) utilizes the also apparent formality of winding of rivet (D) numerous and diverse, processing time consuming; Be with regard to consumer and manufacturer on both side with regard to, be to have the defective that practicality is not good and economic benefit can't effectively promote.

The purpose of this utility model is: a kind of structural improvement of leisure chaise longue is provided, makes its pivot knot support leisure chaise longue firm and that can be formed on dismounting, conveniently clean.

The utility model is to realize above-mentioned purpose like this: establish with the two inboard relatively pivot cakings that form groove in the joint of the pivot that will intersect knot, and form the inserted link of tool circular groove in the two ends of pivot caking, and when making it open, the groove offset face that available groove connects supports mutually and supports, reduce the shearing of the rivet that is pivoted, and the circular groove that utilizes inserted link makes the body of cover group make the tube wall indent embed circular groove with impact style by directly relative circular groove, make it fixed, be provided with a C shape clasp and a sleeve in the horizontal arm pivot end of chair cloth in addition, and with the fastening of C shape clasp or take off, make sleeve can be solidly plugged in support body or give in contract so that horizontal strut can pull down, in order to taking out chair cloth cleaned and changed.

Adopt the leisure chaise longue of this kind structure, except that considering the convenience that can amount to, more note the steadiness of support body and the cleaning problems of chair cloth, people are sat face upward and all have the sense of security, and very comfortable.

Fig. 8 is the schematic diagram of known leisure chaise longue pivot getting customs clearance joint.

(2) figure number is partly:

(1) U-shaped pipe (11) vertical tube

(12) active joint (121) pivot hole

(2) handrail tube (21) short sections

(3) chair back arm (4) horizontal branch pipe

(41) sleeve pipe (411) pin

At first consult shown in Figure 1, this is novel to be to include two U-shaped pipes (1), two L type handrail tubes (2), two＜type chair back arms (3), two horizontal branch pipees (4), support thumb (5), seat cloth (6) and chair back cloth members such as (7), wherein this two U-shapeds pipe (1) is established a joint (8) in vertical tube (11) stage casing of both sides, and in the top of two vertical tubes (11) respectively with short sections (21) and chair back arm (3) pivot of two active joints (12) with handrail tube (2), and wearing seat cloth (6) with a horizontal branch pipe (4) between two active joints (2) gives fixed, the then direct noose of other chair back cloth (7) is in the epimere of two chair back arms (3), and this novel primary structure feature is to be:

This joint (8) forms groove (811) with two pivots cakings (81) in its opposite side, and oblique one-tenth one inserted link (82) outside two ends are reverse, the body of rod also is provided with two road circular grooves (821), in addition, two pivots cakings is to wear the pivot rivet clasp with rivet (83) between (81), and it is when launching, and two pivots cakings (81) are suitable can be involutory, and groove (811) just abuts against in pivot caking (81) two ends with the formed terrace of inserted link (82) (812), becomes a strong fix state; And in these horizontal branch pipe sheathed sleeves of (4) one ends (41), and between sleeve pipe (41) stack shell and horizontal branch pipe (4) end noose one dismountable C shape clasp (42), make a tube end pin (411) can be inserted in the pivot hole (121) of active joint (12) with restriction sleeve (41) location or withdraw from.

As shown in Figure 2, with this novel joint (8) with U-shaped pipe (1) insert group and after making each active joint (12) and the body winding of Yu finish and give folding, the relative groove (811) of its two U-shapeds pipe (1) and joint (8), it is the branch that makes its unlikely formation inside and outside, mat it, as shown in Figure 3, be can make two U-shaped pipes (1) and put and utilize stamping machine directly to go up relatively in two U-shaped pipes (1) punching press of pipe interpolation pole (82) circular groove (821) makes its phase build-in, processing is simple and rapidly.

In addition, when this novel expansion vertically-arranged, shown in Fig. 4,5, two pivots in joint (8) cakings (81) are to be involutory in its two U-shapeds pipe (1), and the terrace (812) of inserted link (82) end can fasten in pivot caking (81) two ends, and make joint (8) become a close positioning state, make the unlikely complete grantee's body weight of rivet (83) of pivot knot, thereby increase the service life of whole chair body; In addition brace (5) is tied and to be prevented that the chair body from folding accidentally.

Again, shown in Fig. 2,6, this novel support body utilizes the design of each joint (8) and active joint (12), is can be used in to fold, and is easy to carry and goes out, and is quite convenient; Moreover, as shown in Figure 7, the sleeve (41) of horizontal branch pipe (4) the one rod end that this is novel is movable, and be provided with a C type clasp (42), when taking off C type clasp (42), the sleeve of this rod end (41) be can in contract, make pin (411) break away from the pivot hole (121) of active joint (12), and make horizontal branch pipe (4) take off, so that seat cloth (6) is split out, be beneficial to cleaning.
