Abstract

The utility model relates to an office chair. The crossed part on both sides of a seat pad and a backrest is provided with an L-shaped side frame, the top end of the L-shaped side frame extends out a first engagement part, the action end of a handrail which is abutted and contacted by human elbow is provided with a second engagement part, the second engagement part and the first engagement part are corresponding and shrinking, and a shrinking central through hole of the two members passes by a pin rod and matched tightly with the pin rod to be in pivot joint into integration; when the handrail is lain downward, the handrail passes by an erected recess on the bottom and is crossed on a lying frame of the handrail of the L-shaped side frame; when the handrail is lifted upwards and closed, the handrail passes by a end face of the boundary and is abutted with a block plane on one end of the L-shaped side frame to form simple structure and portable operation chair handrail.

Description

Office seating

The utility model relates to a kind of office seating.

Though such as at present for common people institute generally the seat of use be the wooden system of traditional type, the seat that rattan matter system or other materials are processed, perhaps be the 0A office seating that the dealer developed in recent years, function is all nothing more than providing the comfortable rest that is seated of people, therefore, various seat has seat cushion nothing more than possessing, backrest, the chair pin, and look and make use and the Armset member that whether needs, if common one the seat both sides be assembled with handrail mostly be directly adopt fixed, but the handrail that adopts the pivot joint form is arranged also, move to make things convenient for the user when not needing handrail, it can be pulled backward, not influence the operation acts regional extent of hand, yet, this kind adopts all suitable usually numerous and diverse of the armrest of pivot joint form, need the multiple tracks procedure, assembling takes artificial, and the seating product that machines is on the high side;

The purpose of this utility model is to provide a kind of its armrest simple, easy and simple to handle and office seating that processing cost is low.

For reaching above-mentioned purpose, the utility model adopts following design: a kind of office seating, and it includes:

Two L shaped bogie side frames, its corresponding locking is in the seat cushion and the backrest intersection both sides of seat;

Two handrails, it is the armrest of default appearance, is assembled into one with the L shaped bogie side frame upper end that is close to;

It is characterized in that: the center that is extended with, the upper end of described L shaped bogie side frame has first convergence part of horizontal perforation, and the rear end of complying with first convergence part is formed with a retaining and establishes the plane, and the front end of convergence part is formed with a handrail and keeps flat frame;

The center of being respectively equipped with, effect end both sides of described handrail has second convergence part of horizontal perforation, be formed with the notch of the corresponding fit in first convergence part of the L shaped bogie side frame of a confession in the centre of second convergence part, should be provided with the boundary end face between notch one end in the middle of second convergence part, both sides, establish plane place and form orientation boundary when folding up carrying moving supporting when folding for handrail at the retaining on L shaped bogie side frame top, be provided with forward along the second convergence part bottom side and set up recess, keep flat the frame place for handrail normally being level recess handrail that extends at L shaped bogie side frame that just can bridge that sets up of its bottom when putting forward, it is fashionable that second convergence part, both sides that this handrail effect end is provided with is overlapped mutually in first convergence part of extending with L shaped bogie side frame upper end, run through in regular turn by pin rod that two members are articulated is one.

The perforation that first convergence part of second convergence part, both sides that this handrail was provided with and L shaped bogie side frame upper end connects interleaves the pin rod of inserting, and adopts the incompatible pivot joint of close-fitting of suitable packing degree.

The utility model is owing to adopting above design, the following advantage of its tool: 1, the utility model is because the armrest composition is very simplified, and the manufacturer is die sinking and a large amount of processing that is shaped easily, and the processing cost of its relative member can so significantly reduce.

2, the utility model since second convergence part, both sides that is provided with of its handrail effect end overlap mutually in first convergence part of extending with L shaped bogie side frame upper end fashionable, running through the pivot joint of two members in regular turn by pin rod is one, common people at ordinary times visual itself required with handrail be level to steadily set up, or up carry moving to make to be and be close to the L shaped bogie side frame boundary orientation of vertical deduction at seat, and be another collapse state stably, reach and keep flat or effect that folding is easy and simple to handle.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is that armrest member of the present utility model is in three-dimensional exploded view

Fig. 5 is that armrest of the present utility model is in the action schematic diagram that up folds

Fig. 6 is that armrest of the present utility model is in the floor map that is installed in seat

As shown in Figure 1, the utility model comprises two L shaped bogie side frames 1, two handrails 2.

Two L shaped bogie side frames 1, its corresponding locking is at the seat cushion 3 and side, boundary, backrest 4 both sides of seat, the center that is extended with has first convergence part 11 of horizontal perforation 12 in the upper end along L shaped bogie side frame 1, the rear end of complying with first convergence part 11 is formed with a retaining and establishes plane 13, forms a handrail by the front end of convergence part 11 and keeps flat frame 14.

Two handrails 2, it is the armrest of default appearance, for being assembled into one with L shaped bogie side frame 1 upper end that is close to, these handrail 2 its effects center of being respectively equipped with, both sides then of holding has second convergence part 21 of horizontal perforation 22, and be formed with first convergence part, the 11 corresponding fits that a notch 23 comes for L shaped bogie side frame 1 in the centre of second convergence part 21, should establish boundary end face 24 between notch 23 1 ends in the middle of second convergence part 21, both sides, and establish forward along second convergence part, 21 its bottom sides and set up recess 25.

As Fig. 2, Fig. 3, shown in Figure 4, during assembling, first convergence part, 11 mutual fits for second convergence part 21 with L shaped bogie side frame 1 upper end that two handrails, 2 effect ends are set,, two members are articulated be integral (as shown in Figure 6) in regular turn through the

center perforation

22,12 of second convergence part 21, first convergence part 11 and mistake by a pin rod 5; As shown in Figure 3, handrail 2 is down kept flat, this moment, the recess 25 that sets up of handrail 2 bottoms kept flat frame 14 places for the suitable handrail that extends at L shaped bogie side frame 1 that can bridge forward, and is like this, can provide people's elbow comfortable by touching on the surface of handrail 2; In addition when the user when working as thinking that the handrail 2 of seat both sides influences the activity of people's hand, then one side or both sides handrail 2 up can be folded (as shown in Figure 5), at this moment, the handrail 2 that the user only needs the to desire folding slightly application of forces makes it up carry moving, and the boundary end face 24 that makes handrail 2 one ends conflicts stably and establishes 13 places, plane at the retaining of L shaped bogie side frame 1 top rear side, just can make handrail 2 be really up folding stably.

Claims

1, a kind of office seating, it includes:

2, office seating as claimed in claim 1 is characterized in that: the perforation that first convergence part of second convergence part, both sides that this handrail was provided with and L shaped bogie side frame upper end connects interleaves the pin rod of inserting, and adopts the incompatible pivot joint of close-fitting of suitable packing degree.
