Description

A kind of armrest

Technical field

The utility model relates to a kind of armrest, is specifically related to a kind of armrest positions adjustable seat handrail, belongs to the technological improvement of armrest.

Background technology

Present armrest generally all is changeless, and the position is unadjustable, and the distance between handrail angle, two handrails can not vary with each individual, so people's ancon leans against and is difficult to reach the optimal comfort effect on its handrail.Prior art also has a kind of handrail to move forward and backward and the armrest of rotatable adjustment angle, the patent of invention that a kind of name is called " a kind of handrail " (patent No. ZL200310101553.8) was once disclosed as Chinese patent, described handrail comprises armrest support, jib, gripper shoe, liner, described armrest support comprises the seat flange, sleeve pipe, the seat flange connects on the seat, have groove on the seat flange, can lie across orientation of chair and move, jib can be along the longitudinal movement and can be connected with the swivel bearing that is installed in cannula tip by tumbler and rotate by guide.Adopt the armrest of this structure, though can carry out all around position adjustments and handrail is carried out the angle rotation to it, but obviously adopt the some connected mode of swivel bearing and tumbler, it is stable that the handrail rotation status is difficult to keep, and the distance adjustment between two handrails is that the change by whole handrail and seat link position realizes, regulate inconvenience, need specialist tools to realize.

Summary of the invention

The purpose of this utility model be to provide a kind of convenient regulate move forward and backward, the more stable armrest of state of move left and right and rotation.

The purpose of this utility model is achieved in that a kind of armrest, comprise armrest support, sliding seat and ancon support member, ancon support member bottom is threaded with sliding seat, described armrest support comprises the seat flange, support column, mount pad, it is characterized in that: the inboard symmetry at the close midline position of described mount pad is hinged with first arm of force, second arm of force, first arm of force, second arm of force can be respectively that pivot is rotated with the pin joint, be provided with first column away from first arm of force pin joint, one end, be provided with second column, first column away from second arm of force pin joint, one end, the second column center has threaded connection hole; Have gathering sill in described sliding seat, first column, second column place in the gathering sill, and sliding seat is connected on first column, second column by screw thread.

Described sliding seat is provided with the tooth bar parallel with gathering sill, and first column is connected by screw thread with sliding seat after being positioned at sliding seat top socket one contiguous block, and described contiguous block bottom is provided with a gear, and described gear is meshed with described tooth bar.

Described mount pad is positioned at the center line two ends and is respectively equipped with limited block.

Good effect of the present utility model: the inboard symmetry at the close midline position of mount pad is hinged with rotatable first arm of force, second arm of force, in sliding seat, have gathering sill, first column of first arm of force and second column of second arm of force place in the gathering sill, sliding seat is connected first column by screw thread, on second column, sliding seat mount pad is relatively made the front and back back and forth movement, simultaneously, first arm of force, the rotation of second arm of force, make and then motion of sliding seat, when first arm of force, when second arm of force rotates synchronously, the relative mount pad move left and right of sliding seat, when having only an arm of force rotation, perhaps two arm of force rotations are asynchronous, and sliding seat generation angle changes, and realizes the rotation adjusting.

The sliding seat tooth bar cooperates with the gear of contiguous block, makes the relative mount pad motion of sliding seat steadily.Mount pad is positioned at the center line two ends and is respectively equipped with limited block, to first arm of force, that second arm of force is rotated angle is spacing.

The specific embodiment

Below in conjunction with accompanying drawing the utility model specific embodiment is elaborated.

As Fig. 1-shown in Figure 5: armrest described in the utility model, comprise armrest support 1, sliding seat 2 and ancon support member 3, sliding seat 2 is provided with threaded mounting hole 23, ancon support member 3 bottoms and sliding seat 2 are connected by screw thread, and described armrest support 1 comprises seat flange 11, support column 12, mount pad 13.Inboard symmetry at described mount pad 13 close midline positions is hinged with first arm of force 41, second arm of force 42, first arm of force 41, second arm of force 42 can be respectively the pivot rotation with the pin joint, be provided with first column 411 away from first arm of force, 41 pin joints, one end, away from second arm of force, 42 pin joints, one end be provided with second column, 421, the first columns 411, second column, 421 centers have threaded connection hole; In described sliding seat 2, have gathering sill 21, first column 411, second column 421 place in the gathering sill 21, be with elastomeric pad, plain cushion being positioned on first column 411 above sliding seat 2 gathering sills 21, second column 421, sliding seat 2 is connected on first column 411, second column 421 by screw thread, and sliding seat 2 mount pad 13 is relatively made the front and back back and forth movement.Described mount pad 13 is positioned at the center line two ends and is respectively equipped with limited block 6, limited block 7, to first arm of force 41, that second arm of force 42 is rotated angle is spacing.

As further improvement of the utility model, have the tooth bar 22 parallel in the sliding seat 2 with gathering sill 21, socket one contiguous block 5 on first column 411 that is positioned at above sliding seat 2 gathering sills 21, sliding seat 2 is connected on first column 411 by screw thread, contiguous block 5 bottoms are provided with a gear 51 (see figure 3)s, described gear 51 is meshed with described tooth bar 22, makes the relative mount pad motion of sliding seat steadily.First arm of force 41, second arm of force 42 shown in Figure 5 are in initial position, and this moment, the ancon support member 3 of armrest was parallel with the lengthwise position of chair, and the handrail of the right and left is apart from maximum.Armrest shown in Figure 6, first arm of force 41, second arm of force 42 rotate on maximum angle, and this moment, the ancon support member 3 of armrest was parallel with the lengthwise position of chair, and the handrail of the right and left is apart from minimum.Armrest shown in Figure 7, first arm of force 41 rotates on maximum angle, second arm of force is in the home position, at this moment, ancon support member 3 front ends are inside, the outward-dipping certain angle in rear end, certainly, also can be in the home position to first arm of force 41, second arm of force rotates on maximum angle, and it is outside to form ancon support member 3 front ends, the slope inwardly user mode of certain angle of rear end, and first arm of force 41, second arm of force 42 rotates to an angle respectively, makes ancon support member 3 be in different directions, the various user modes of diverse location can both reach best level of comfort to reach when the hand that is fit to everyone is placed on the handrail.
