Abstract: A desk includes two first legs and two first support members extending from the two first legs so as to support a first top on the two first support members. Two second support members respectively extend from the two first legs and are located below the two first support members. Two first rods are retractably received in the two second support members and each of the first rods is connected to a connection frame so that a second top is supported on the two connection frames. Two second legs with wheels are respectively connected to the first rods. Two sleeves are respectively connected to the two connection frames and two second rods are retractably received in the two sleeves. A third top is supported on the two second rods.

Abstract: A keyboard support device for a desk includes two posts each having a catching member so as to slidably engage with a beam connected below a top of the desk. Two rails each have a socket connected to a first end thereof so that the two sockets are respectively pivotally connected to the two posts. Each rail has a member slidably received in a second end thereof and a bar is connected between the two rails so as to maintain the two rails in parallel with each other. A tray is connected to the two members so that a keyboard is put on the tray. The tray can be pivoted and moved relative to the top of the desk.

Abstract: A desk includes two inverted U-shaped frames connected with each other and each frame has two legs connected by a bar. A top supported on the two bars of the two frames. Each leg of the two frames has a tube connected to a distal end thereof and each tube has an open end so as to be pivotally connected to an auxiliary device such as a document tray or a support platform.

Abstract: A computer office table structure includes an upstanding rod having a lower end fixed to a supporting base and an upper end provided with a shoulder, a supporting post extending upward from the shoulder and having a diameter smaller than that of the upstanding rod, a first table supporting member provided with a plurality of crossbars and including a first end provided with a first extension bar having a first sleeve rotatably mounted on the supporting post, and a second end provided with a first table leg and two first rollers each rotatably mounted on the first table leg, a second table supporting member provided with a plurality of crossbars and including a first end provided with a second extension bar having a second sleeve rotatably mounted on the supporting post and a second end provided with a second table leg and two second rollers each rotatably mounted on the second table leg, two table plates each mounted on the first table supporting member and the second table supporting member, and a supporting

Abstract: A device for connecting an auxiliary desk to a main desk includes two frames attached to the underside of the main desk and each of the two frames having a groove defined therein for a slide movably received between the two frames. An inverted T-shaped connecting member is connected between the connecting member and the auxiliary desk wherein the connecting member is rotatably connected to the slide so that the auxiliary desk is slid and pivoted relative to the main desk.
