Chair armrest 15 was that mode with " fixing " is fixed on chair tool both sides in the past, when the user is sitting on the seat cushion 12, health and when leaning forward work (for example beaing computor-keyboard), because handrail 15 armrest bodies 153 can't move forward, user's elbow can't cause the inconvenience in the use by being located on the armrest body 153.

Main purpose of the present utility model is to provide a kind of handrail that can need adjust the chair tool of front and back position for elbow by the armrest body of establishing with sitting posture.

The purpose of this utility model reaches as follows:

A kind of handrail of chair tool comprises the bracing frame that is arranged on chair tool seat cushion side, and bracing frame one end is fixed on the seat cushion both sides, and an armrest body is set on the other end; It is characterized in that:

Flatly the microscler location division of a position at the seat cushion side extended in front and back on the other end of bracing frame, set firmly above this location division one with the location division above the microscler connector of fitting, dual-side at this connector is provided with corresponding chute, the armrest body is microscler and top that be installed in this connector, and armrest body bottom is provided with two draw runners that embed described connector chute slidably.

The purpose of this utility model can also following mode reach: the handrail of described chair tool is characterized in that: the location division of this bracing frame, connector and armrest body are arc-curved shape.

The handrail of described chair tool, it is characterized in that: this armrest body is made with flexual plastics and its two draw runner one ends form blind end, outstanding block on the open end of opposite side, the scalene cone of this block is towards the lateral surface of armrest body, and its vertical stop surface is then towards blind end.

The handrail of described chair tool is characterized in that: the location division of support frame as described above is a tubulose, is fixed on connector on the location division corresponding position that fits and is the arc applying edge face of indent.

Described Chair armrest is characterized in that:

The location division of support frame as described above is provided with most locating holes, and described connector is provided with and the corresponding countersunk of locating hole.

Effect of the present utility model is: can adjust front and back position for hand because of sitting posture is different by the armrest body of establishing, make handrail more comfortable in the use.

Be elaborated below by most preferred embodiment and accompanying drawing handrail to the utility model chair tool, in the accompanying drawing:

Fig. 1 is a kind of schematic perspective view of the tool of chair in the past.

Fig. 2 is the three-dimensional exploded view of the utility model one preferable possible embodiments.

Fig. 3 be the utility model one preferable possible embodiments overlook the adjustment schematic diagram.

Fig. 4 is vertical sectional exploded view of the utility model one preferable possible embodiments.

Fig. 5 is the horizontal assembled sectional view of the utility model one preferable possible embodiments.

Fig. 6 is the horizontal assembled sectional view of another preferable possible embodiments of the utility model.

As Fig. 2,3, the Chair armrest of the utility model embodiment is fixed on seat cushion 21 both sides of chair tool 2 in couples, and each handrail also comprises respectively: bracing frame 3, a connector 4 and an armrest body 5.

One end of bracing frame 3 is fixed on seat cushion 21 sides of chair tool 2, and the location division 31 of extending before and after flatly on the other end is the pipe of curved arc shape, and the position is in the both sides of seat cushion 21, on this location division 31, wear a plurality of directly to locating hole 311.

Connector 4 is arc curvatures and the identical strip block in bracing frame 3 location divisions 31, these connector 4 bottom surfaces cooperate the location division 31 of bracing frame 3 to form applying edge face 41, connector 4 dual-sides form the chute 42 of an indent correspondence respectively, top 42 of two chutes forms an arc-plane 43, wear most and bracing frame 3 locating holes 311 corresponding countersunks 44 on the plane 43 again, these countersunk 44 apical margins are provided with the bigger recessed edge 441 of diameter, retaining element 45 ends of being assembled in it are fixed in the locating hole 311 of bracing frame 3, make connector 4 be installed in bracing frame 3 tops.

See also Fig. 2,4, the armrest body 5 that arc curvature and connector 4 match, make by flexual plastics, its top supporting surface 51 abuts against for user's hand, can cooperate the design of chair tool 2 to coat flannelette or surface, according to outstanding two draw runners that parallel 52 of armrest body 5 arc curvatures, 52 width of draw runner are identical with the width of connector 4 below supporting surface 51 in the position, and 521 of the beads that extend to central authorities its bottom can snap in two chutes 42 of connector 4.Cause separation between the two when preventing armrest body 5 with respect to connector 4 slippages, draw runner 52 1 ends form blind end 522, then outstanding downwards block 53 on the open end 523 of opposite side, the scalene cone 531 of above-mentioned block 53 is towards the lateral surface of armrest body, and its vertical stop surface 532 is towards blind end 522.

Please cooperate Fig. 4,5, when present embodiment in when assembling, connector 4 is erected on the location division 31 of bracing frame 3, make both locating holes 311 corresponding with countersunk 44, in it respectively spiral shell establish retaining element 45, just connector 4 is fixed on the bracing frame 3, the end 451 of fixing back retaining element 45 can be sunk in the recessed edge 441 of countersunk 44; Armrest body 5 have the side of block 53 1 ends corresponding to connector 4 after, two chutes 42 of the corresponding connector 4 of 521 while of bead of armrest body 5 bottoms are laterally inserted again, because the scalene cone that is provided with on the block 53 531 is the lateral margin of corresponding connector 4 earlier, so block 53 can slightly be suppressed during socket, when making block 53 cross the ora terminalis of connector 4 when armrest body 5 lasting lateral displacements, through stopping of vertical stop surface 532 on the block 53, can make 5 firm being assembled on the connector 4 of armrest body.

See also Fig. 3,4, during use, can promote armrest body 5 and adjust the position, make chair tool 2 more comfortable in the use, convenient according to the needs on the sitting posture; Be subjected to the restriction of armrest body 5 bottom blind ends 522 and block 53 stop surfaces 532 during adjustment, this armrest body 5 can not break away from connector 4; And with regard to the design of present embodiment, the bead 521 and the chute 42 of clamping also can be common swallow-tail forms, for the block 53 that prevents that connector 4, armrest body 5 from separating in adjusting, also can adopt the grab design that can in connector 4, fold, to increase the easiness of assembling.

Armrest body 5 is with respect to connector 4 slippages the time, do not have locating effect to each other, after being adjusted, it can locate, the utility model also can be as Fig. 6, go up shrinkage pool 46 of formation at connector 4 ', steel ball 48 that shored by spring 47 of assembling in this shrinkage pool 46, and armrest body 5 ' the inner face correspondence position of phase clamping forms the hole clipping 54 of row's indent, the location that aforementioned steel ball 48 of mat and hole clipping are 54 can make armrest body 5 ' be located with respect to connector 4 ' slippage the time.
