The utility model can be implemented in the interior in a big way anglec of rotation of adjusting little foot rest arbitrarily owing to adopt technique scheme by hinge type bound feet frame angle adjuster, selects suitable bound feet chord position to put as required thereby be convenient to the user, uses more comfortable.And the structure of this hinge type bound feet frame angle adjuster adopts Purely mechanical, simple in structure, install easily, production and processing is with low cost, can reduce selling price, is convenient to promoting the use of of massage armchair.

Description of drawings

Accompanying drawing 1 is the structural representation of the utility model massage armchair;

Accompanying drawing 2 is that the A-A of hinge type bound feet frame angle adjuster among Fig. 1 is to the section diagrammatic sketch.

The specific embodiment

Below in conjunction with Figure of description and specific embodiment the utility model is described in further detail.

With reference to the accompanying drawings 1, a kind of massage armchair comprises seat support 3, shank frame 1 and hinge type shank frame angle adjuster 2.

Described hinge type shank frame angle adjuster 2 is arranged at the junction of seat support 3 and shank frame 1, and the two ends of described hinge type shank frame angle adjuster 2 are connected with seat support 3 with shank frame 1 respectively.

For the stationarity of the rotation that guarantees bound feet frame 1, described hinge type shank frame angle adjuster 2 has a pair of, and they are symmetricly set in the both sides of shank frame 1 and seat support 3 junctions.

With reference to the accompanying drawings 2, described shank frame angle adjuster by decide bar 8, moving bar 4 constitutes.

One end of described moving bar 4 in a tubular form, and be fixed on the shank frame 1, its other end is a pair of long jig arm 11, the top of described jig arm 11 is provided with torque spring 5 and screens piece 7, described screens piece 7 is loaded in the jig arm 11 by rivet shaft with torque spring 5, and on the inwall of an end Zhi Yudong bar 4 of described torque spring 5, its other end is on screens piece 7, the front end of described screens piece 7 has latch 14, and the bottom of described jig arm 11 offers hinge hole 15.

A described end of deciding bar 8 in a tubular form, and be fixed on the seat support 3, its other end is a pair of jig arm 10 that is sub-circular, the circle centre position of described jig arm 10 also offers hinge hole corresponding to hinge hole 15 places on the moving bar 4, thereby jig arm 10 is inserted in the jig arm 11, and hinged by the rivet that penetrates two hinge holes with jig arm 11.Be symmetrically arranged with plurality of gears 12 on the periphery of described jig arm 10.Described gear 12 mates with the latch 14 of screens piece 7, thereby can mesh with latch 14.Described latch 14 is made of long latch and stub tooth.

Be provided with shifting block 13 between described two jig arm 10 of deciding bar 8, described shifting block 13 is in deciding the hinged jig arm 11 of going into bar 4 of bar cramp arm 10, its side is that the arcwall face in axle center is formed by connecting by multistage with the hinge hole 15 hole hearts, and wherein the radius of one section arcwall face 13a of radius maximum is decided the cog length in 12 the described axle center of vertex distance of bar greater than described.

Be provided with a spacing block set 9 in described two jig arm 10 of deciding bar, an end arcwall face 13b of the radius minimum of the side surface of described spacing block set 9 and described shifting block 13 is tangent.

During work, when shank frame 1 is in Fig. 1 state (when promptly upwards near normal is overturn), the duty of hinge type shank frame angle demodulator 2 as shown in Figure 2, at this moment, directly over the arcwall face 13a of the maximum radius of shifting block 13 is in, because its radius is greater than the length of gear apart from the axle center, therefore, arcwall face 13a is with the latch 14 of screens piece 7 jack-up upwards.This moment, moving bar 4 can be around deciding bar 8 unresisted rotations.Because spacing block set 9 is tangent with an end arcwall face 13b of the radius minimum of shifting block 13, therefore, during rotation, the two ends of spacing block set 9 contact with the junction of the arcwall face of both sides with the least radius arcwall face 13b of shifting block 13 respectively, thereby play the effect of the anglec of rotation of limit brake bar 4.

Be rotated counterclockwise shank frame 1, being about to shank frame 1 puts down, moving bar 4 is rotated counterclockwise to the left end of spacing block set 9 and pushes up shifting block 13, at this moment, the counterclockwise pressure rod 4 of exerting oneself slightly, latch 14 slips over the maximum radius arcwall face 13a of shifting block 13 counterclockwise, and slips in the gear 12 under the effect of torque spring 5.So just shank frame 1 is put down fully, because a side of described gear 12 is the inclined-plane that favours the side surface of moving bar cramp arm 10, opposite side is facing directly perpendicular to the side surface that moves bar cramp arm 10, in the present embodiment, the direction that described inclined-plane tilts is counterclockwise, therefore, at this moment, shank frame 1 is owing to the resistance of facing directly that latch 14 is subjected to gear is fixed.

At this moment bar 4 is rotated in dextrorotation again, and latch 14 meshes, separates with all gears 12 successively, because the drag effect of facing directly of gear, shank frame 1 can be fixed in last process of lifting at any time, and the good stability of location.

Shank frame 1 can more than lift to latch shown in Figure 2 14 by the jack-up state.

From the above, the utility model can be realized 180 any adjustment angles of spending in perpendicular of shank frame by adopting hinge type shank frame angle adjuster, and all can fix arbitrarily angled, and its good stability the pin phenomenon can not occur falling.And by being symmetrical arranged two groups of angle adjusters, thereby guarantee the stability and the degree of balance of little foot rest.In a word, relative prior art, the utility model use is convenient, structure is simple more, performance is more superior, cost is cheaper.
