Detailed ways

Please refer to FIG. 1 , the present invention is that a table board 1 is installed at the front end of the armrest 2 of the chair. The side and front sides of the table top 11 of the table board 1 are respectively provided with a brush slot 12 and a handheld device stand. Put the slot 13, at the same time, the table board 1 is pivoted on a pivoting part 21 provided at the front end of the chair armrest 2, which can be rotated, turned and positioned, and the rear end of the chair armrest 2 can pass through a The pivotally connected connecting piece 22 is connected and fixed with the frame or the legs of the chair.

On the other hand, the installation method between the table top 1 and the chair armrest 2 is shown in Figures 2 to 4. A pivot groove 210 is provided on the pivoting part 21 at the front end of the chair armrest 2, and the A accommodating space 14 is provided in a corner of the table top 1, and a pivot hole 17 is defined in the middle of the accommodating space 14, and a positioning element 3 with a pivot portion 31 is further accommodated in the accommodating space 14, Make the pivot portion 31 pivotable in the pivot hole 17, and then set a top cover 4 to pass through the positioning element 3 through the fixing element 5 at the same time, and lock the positioning element 3 on the pivoting portion 21. .

On the table top 1 corresponding to the pivot groove 210 on the front end pivot portion 21 of the armrest 2 of the chair, a pivot protrusion 18 that can be pivoted into the pivot groove 210 is protruded to allow the table top 1 is pivoted between the positioning element 3 and the pivoting part 21, so that the table board 1 can be rotated in the horizontal direction, so that the table board 1 can be pushed inward to be in a state of use, or pushed out to be open. state.

In addition, the front end of the positioning element 3 is provided with an elastically retractable positioning protrusion 33 with elastic expansion and contraction effect, and the table board 1 in the receiving space 14 of the table board 1 is positioned at the opposite position when the table board 1 is pushed into the use state. There is a first positioning groove 151 into which the retractable positioning protrusion 33 can be inserted, and a second positioning groove 152 in which the elastically retractable positioning protrusion 33 can be inserted at the opposite position when the table board 1 is pushed out to the open state. .

A first stop portion 321 and a second stop portion 322 are respectively provided on both sides of the positioning element 3, and the table board 1 in the accommodating space 14 of the table board 1 is also positioned when the table board 1 is pushed into the use state. There is a first stop portion 162 that can be held by the first stop portion 321 at the opposite position, and a second stop portion 322 can be positioned at the opposite position when the table board 1 is pushed out to the open state. the second stopper 162 .

Therefore, through the above-mentioned combination method between the table top 1 and the chair armrest 2, the table top 1 can be moved on the chair armrest 2 as shown in FIG. 5, that is, when the table top 1 is pushed inward horizontally In the state of use, the elastically retractable positioning protrusions 33 on the positioning element 3 are just inserted into the first positioning grooves 151, and at the same time, the first abutting parts 321 on the positioning element 3 are just abutted against the first The blocking portion 161 prevents the table top 1 from turning inward excessively, and at the same time prevents the positioned table top 1 from being easily pushed outwards.

On the contrary, as shown in FIG. 6 , when the table board 1 is pushed out in the horizontal direction and is in an open state, the elastically retractable positioning protrusions 33 on the positioning element 3 are just inserted into the second positioning grooves 152 , and at the same time, the positioning element 3 is inserted into the second positioning groove 152. The second abutting portion 322 also just abuts against the second stopping portion 162 of the table top 1, which also prevents the table top 1 from turning outwards excessively, and at the same time prevents the positioned table top 1 from turning outward. can be easily pushed inward.

To sum up, for users who still want to continue to use the chair and the table top is full of things, as long as the table board 1 is pushed outward to make room in front of the chair, they can easily leave the seat without the need for Pick up the items on the desktop; otherwise, after the user returns to the seat, he only needs to push the table top 1 back to the original position to continue using the table top, thus increasing the convenience in use and operation of the table top 1 .
