The specific embodiment

For making the utility model clear and definite more full and accurate, enumerate preferred embodiment now and cooperate following diagram, structure of the present utility model and technical characterictic thereof are described in detail as the back:

With reference to figure 1～shown in Figure 3, handrail 1 of the present utility model be locking on the end face of armrest support 2, comprise a handrail face 10, once disk body 20, a underframe 30, a movable block 40, a square plate 50, a disk 60, locating ring 70 and the elastic component 71 that matches thereof, dowel 80 and the elastic component 81 that matches thereof.

Described handrail face 10 can be combined with a hardboard layer 12 by a cushion course 11 and constitute, cushion course 11 can be plastics, rubber or foaming thing, to provide staff good sense of touch, and hardboard layer 12 can be iron plate or plastic plate, and ring periphery is provided with several screws 13 for locking with the corresponding screw 21 of following disk body 20 on it; Described disk body 20 down is polymer housings, is integral with 12 locking of hardboard layer, makes and forms a rectangle inner space between handrail face 10 and the following disk body 20, for the adjustment associated components is set.

Two symmetrical in line locating slots 22 are established on the left and right limit of following disk body 20 inner sides (leading portion or back segment), it is to be arranged by the arc groove 23 of several equal sizes to constitute, and two symmetrical strip flanges 24 are established on the left and right limit of opposite side, make strip flange 24 belows form a chute.

Movable block 40 is to be set in down in the disk body 20, and its transverse edge can insert in the chute of strip flange 24 belows and slide relatively, and its length is less than disk body 20 inner length down again; The left and right limit of a side is provided with two symmetrical tanks 41 on the movable block 40 again, supply a ccontaining respectively locating ring 70 and elastic component 71 in order to urge locating ring 70, with the locating slot 22 of correspondence in following disk body 20, movable block 40 can lived relatively down in the disk body 20 after the slip of front and back by means of an arc groove 23 in the involutory locating slot 22 of locating ring 70 elasticity and location; Nearly middle place establishes a square groove 42 on the movable block 40 again, and square groove 42 inner sides are provided with a cross slide way 43, and the place establishes a lateral trench 44 approximately; A tank 45 is established for a ccontaining locating ring 70 and the elastic component 71 in order to urge locating ring 70 in square groove 42 1 sides again, and locating ring 70 can be urged to square groove 42 inner elastomeric.

Square plate 50 is to be set in the square groove 42, and its bottom surface is established a groove 51 and is enclosed within on the guide rail 43 with correspondence, and its transverse width is less than square groove 42 inner widths again; One in line several arc grooves 52 are set on square plate 50 1 lateral margins again,, make square plate 50 in square groove 42, relatively laterally can rely on locating ring 70 elasticity in the tank 45 that unification arc groove 52 is located after the slip with the tank 45 of correspondence at movable block 40; Establish a circular groove 53 again on the square plate 50, a centre bore 54 is established in circular groove 53 bottom surfaces: establish a tank 55 again on the ring rim of circular groove 53 for a ccontaining dowel 80 and the elastic component 81 in order to urge dowel 80, dowel 80 can be urged to circular groove 53 inner elastomeric; And above-mentioned

elastic component

71,81 can be the rubber ring body of a tool malleable, can rely on malleable own and oppress locating ring 70, dowel 80 outside elasticity protrude out.

Disk 60 is to be set in the circular groove 53 of square plate 50, its bottom forms a scalariform bulge loop 61 shown in Fig. 2 A, be inserted in correspondence in the centre bore 54 of circular groove 53 bottom surfaces, a square shrinkage pool 62 is established for cooperating the lock hole seat 31 on the underframe 30 and being inserted in sealed in bulge loop 61 bottom surfaces again; The ring periphery of disk 60 is provided with several locating slots 63 again, with the tank 55 of correspondence in square plate 50, can rely on the involutory locating slot 63 of dowel 80 elasticity in the tank 55 after disk 60 is relatively rotated in circular groove 53 and the location firmly; Locating slot 63 can only be arranged on one section central angle scope of disk 60 ring peripheries shown in Fig. 2,3 again, and then it relatively rotates angle and promptly is subject to set locating slot 63 in the described central angle scope; Locating slot 63 also can be arranged on whole ring peripheries of disk 60 as shown in Figure 4 again, and then it relatively rotates angle and gets final product 360 degree rotations; Disk 60 is to rely on a locking part 64 as locking screw to be passed down through square plate 50, movable block 40 bottom surfaces, one lateral trench 44 by its central shaft hole 65 and the locking hole 32 of on underframe sheet 30 lock hole seat 31 of locking again; And underframe 30 is to press close in following disk body 20 bottom surfaces, and proximal edges place respectively establishes a lockhole 33 on it, is integral for locking with armrest support 2 (as shown in Figure 1) again.

As from the foregoing, but handrail face 10 is the handrails 1 that lock into an interlock with following disk body 20, and disk 60, underframe 30, with armrest support 2 be that locking is integral, so disk 60, underframe 30 with respect to armrest of seat support 2 be maintained fixed motionless; During use,, and can rely on an arc groove 23 in the involutory locating slot 22 of locating ring 70 elasticity and locate because of following disk body 20 slides before and after can doing with respect to movable block 40, make handrail 1 reach before and after displacement adjust effect as before and after Fig. 1 to shown in the arrow; Again because of movable block 40 can laterally move with respect to square plate 50, and can rely on locating ring 70 elasticity in the tank 45 to unification arc groove 52 and the location is lived, make handrail 1 reach transverse shift and adjust effect shown in Fig. 1 lateral arrows; Can do angle with respect to disk 60 because of square plate 50 again and rotate, and can live the location, make handrail 1 reach anglec of rotation adjustment effect and rotate shown in the arrow as Fig. 1 by means of the involutory locating slots 63 of dowel 80 elasticity in the tank 55.

Again with reference to figure 5, Fig. 6, it is respectively the exploded view of another embodiment of the utility model, with part combination state diagram, the operating function of this embodiment, be shifted before and after comprising handrail, rotational angle, adjustment with transverse shift, identical with Fig. 1-3 illustrated embodiment, and the structural difference between two embodiment is to be: a former left side that is located at down disk body 20 inner sides, two symmetrical in line locating slot 22 changes on the right are arranged on the corresponding position on the movable block 40, be that two symmetrical tanks 41 and locating ring 70 were set on the movable block 40 originally, the position of elastic component 71, again with the former tank 41 and locating ring 70 that is located on the movable block 40, elastic component 71 changes are arranged on corresponding position such as Fig. 5 of hardboard layer 12 inside of handrail face 10, shown in 6, when then hardboard layer 12 locking of disk body 20 and handrail face 10 are integral instantly, locating ring 70 still can be corresponding to two symmetrical in line locating slots 22 with elastic component 71, make movable block 40 still can and locate when slide in front and back relatively in following disk body 20, reach the positioning action of front and back displacement adjustment by means of an arc groove 23 in the involutory locating slot 22 of locating ring 70 elasticity.

But above-mentioned graphic and explanation of taking off only is embodiment of the present utility model, and is non-for limiting embodiment of the present utility model; Generally be familiar with the personage of described skill, it complies with feature category of the present utility model, and other equivalence of being done changes or modifies, and all should be encompassed in the claim of following this case.
