The present invention relates to a desk assembly pivotably connected a seat and a positioning device which positions the board-like electronic device.
As shown in
The conventional desk assembly 7 is not designed for positioning the board-like electronic devices which are preferably positioned at an angle relative to the users. However, the conventional desk assembly 7 only provides a horizontal desk top and the users have to operate the board-like electronic device, this is not convenient for the users when using the board-like electronic devices.
The present invention intends to provide a desk assembly connected to the back of a seat and the desk assembly can position the board-like electronic device at an angle relative to the user.
The present invention relates to a desk assembly which comprises a desk top pivotably connected to a seat or the armrest of the seat, and has an angle adjustment unit and a positioning portion. The desk top is flat and suitable for books or magazines put thereon. A rack is pivotably connected to the desk top and has a positioning unit. The positioning unit includes a transverse bar which has a slide slot and two positioning members between. Anti-slip material is connected to the rack. The rack is pivoted and positioned relative to the desk top so that the board-like electronic device such as cellular phone or board-like computer can be supported on the anti-slip material the rack.
The primary object of the present invention is to provide a desk assembly which has a rack pivotable to the desk top so that the board-like electronic device can be supported on the rack and positioned at an angle relative to the user. Anti-slip material is connected to the rack so that the board-like electronic device is positioned.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
a shows the first embodiment of the positioning unit of the rack of the present invention;
b shows the second embodiment of the positioning unit of the rack of the present invention;
c shows the third embodiment of the positioning unit of the rack of the present invention;
Referring to
The desk top 1 is made by carbon fibers, metal, wood, plastic or any desired material, and the desk top 1 is pivotably connected to the back of the seat 4 or to the armrest 41 of the seat 4 as shown in
The rack 2 comprises a transverse bar 21 and two arms 22 which are connected to two ends of the transverse bar 21. The two arms 22 are pivotably connected to the desk top 1. The rack 2 has a positioning unit 23 which has a slide slot 231 defined in the transverse bar 21 and at least two positioning members 232 are slidably engaged with the slide slot 231. The slide slot 231 is a toothed rack or a groove. The positioning member 232 is engaged with or urged to the slide slot 231. Each of the two positioning members 232 has a stop 234 which is pivotably connected to the positioning member 232. Anti-slip material 31 is connected to transverse bar 21 of the rack 2.
There are two embodiments for the connection between the rack 2 and the desk top 1, as shown in
The positioning portion 3 of the desk top 1 has anti-slip material 31 connected thereto and the positioning portion 3 can be a groove 32 as shown in
As shown in
As shown in
The positioning unit 23 has three embodiments which are shown in
b shows that the distal end of the positioning member 232 is located in the slide slot 231 and a resilient member 233 is biased between the inside of the slide slot 231 and the positioning member 232. The resilient member 233 generates the friction between the inside of the slide slot 231 and the positioning member 232 so as to position the positioning member 232. The inside of the slide slot 231 may have a serrated surface to position the positioning member 232. When adjusting the positioning member 232, the positioning member 232 is pulled to compress the resilient member 233 and then moved to the desired position. The positioning member 232 is then released to be positioned at the desired position.
c shows that the positioning member 232 is made by resilient and plastic material such as rubber, and has head with a curved surface 2322 defined in the periphery thereof. A bolt 236 extends through the slide slot 231 and is connected to the positioning member 232. When adjusting the positioning member 232, the positioning member 232 is rotated to be loose relative to the bolt 236 and then moved to the desired position. The positioning member 232 is rotated to be right again to be set at the desired position. The board-like electronic device 5 is engaged with the curved surface 2322.
As shown in
The anti-slip material 31 can be used at the positions where the board-like electronic device 5 is in contact. The anti-slip material 31 can be used on the positioning portion 3, the transverse bar 21 of the rack 2, the top of the positioning member 232 and the inside of the stop 234 to position the board-like electronic device 5.
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
