Description

A kind of armrests

Technical field

The utility model relates to the chair tool, especially relates to a kind of handrail of chair tool.

Background technology

In order to promote the Ride safety of chair, some chair can be loaded onto handrail at its side, in case the people of seat topples over.But common armrests is generally to fix handrail by several screws or bolt, need the assembling elapsed time.And fixing handrail with screw or bolt, the dismounting inconvenience of handrail, need to expend time in and need instrument.When the consumer wouldn't use and chair need to be covered up the time, want to pull down handrail just very inconvenient to reduce space hold.

The utility model content

The technical problem that the utility model mainly solves is to provide a kind of armrests, and this armrests has advantages of does not need the instrument just can fast assembling-disassembling.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of armrests is provided, it comprises intubate, can insert handrail and the elastic top support member of described intubate, every two one group side that is fixed in a chair of described intubate, described two intubate be arranged in parallel, on the perisporium of the upper end of described intubate, be provided with the fastening hole through this perisporium, described handrail is U-shaped, the two ends of the U-shaped opening of described handrail are the tubulose of hollow, on the perisporium at the two ends of the U-shaped opening of described handrail, be provided with through the perforation of the perisporium at described two ends, described perforation is coaxially corresponding with described fastening hole, every two one group of described elastic top support member stays on respectively the inwall at two ends of the U-shaped opening of described handrail, one end of described elastic top support member is provided with the top brace part that runs through described perforation and described fastening hole.

In preferred embodiment of the utility model, described top brace part is column.

In preferred embodiment of the utility model, the junction of described top brace part and described elastic top support member is provided with flange, and the external diameter of described flange is greater than the diameter of described perforation.

In preferred embodiment of the utility model, described elastic top support member is spring or elastic jackstay.

In preferred embodiment of the utility model, the outer peripheral face of the lower end of described intubate is fixed in a described side of described chair by welding or securing member.

Armrests of the present utility model is by pressing and unclamping the elastic top support member in handrail, can rapidly handrail be assembled or disassemble, expend time in and need less and not instrument, that handrail is disassembled to reduce space hold is not very convenient the used time at chair, no matter be that shipment is sold by businessman or household person is used all very convenient.

In figure, the mark of each parts is as follows: 10, feet, 11, cushion, 12, support bar, 13, lean against, 20, armrests, 21, intubate, 22, handrail, 23, the elastic top support member, 210, fastening hole, 220, perforation, 231, top brace part, 232, flange.

The specific embodiment

The utility model is elaborated below in conjunction with accompanying drawing and concrete preferred embodiment, so that advantage of the present utility model and feature can be easier to be understood by those skilled in the art, these embodiment are only illustrative purposes, are not intended to scope of the present utility model is limited.

Refer to Fig. 1 to Fig. 3, armrests 20 of the present utility model comprises intubate 21, can insert handrail 22 and the elastic top support member 23 of described intubate 21, every two one group side that is fixed in a chair of described intubate 21, described two intubate 21 be arranged in parallel, on the perisporium of the upper end of described intubate 21, be provided with the fastening hole 210 through this perisporium, described handrail 22 is U-shaped, the two ends of the U-shaped opening of described handrail 22 are the tubulose of hollow, on the perisporium at the two ends of the U-shaped opening of described handrail 22, be provided with through the perforation 220 of the perisporium at described two ends, described perforation 220 is coaxial corresponding with described fastening hole 210, every two one group of described elastic top support member 23 stays on respectively the inwall at two ends of the U-shaped opening of described handrail 22, one end of described elastic top support member 23 is provided with the top brace part 231 that runs through described perforation 220 and described fastening hole 210.

Further, the chair corresponding with the utility model is provided with four and is supported in ground feet 10, and the middle part of the feet 10 of every two one is bent into the state vertical with the two ends of feet 10, and cushion 11 is set on the middle part of two place's feets 10.Top one end of fixing 12, two L shaped support bars 12 of two L shaped support bars below cushion 11 adheres to be connected with and leans against 13.

Preferably, described top brace part 231 is provided with flange 232 with the junction of described elastic top support member 23, and the external diameter of described flange 232 is greater than the diameter of described perforation 220.After handrail 22 inserts intubate 21 like this, when top brace part 231 passed perforation 220 and fastening hole 210, flange 232 can be stuck in the edge of perforation 220, play the effect of location, top brace part 231 is played the be located by connecting effect of handrail 22 with intubate 21, i.e. handrail installation.
