Abstract

Abstract The subject matter relates to a structural improvement of computer desk, or more specifically to a type of computer desk that can be disassembled or collapsed, with sufficient utilization of storage space, with the height of its desk plate adjustable to suit its application at a regular location, in an office or a Japanese-style room. The subject matter comprises mainly a skeleton and no less than one desk plate, wherein on each of two sides of the skeleton is respectively a leg rack that can rotate freely around a radial shaft lever, with a transverse fixing lever to fix the distance between two radial shaft levers; at each of the front of the two sides of the desk plate is respectively an adjustable bolt hook that can be hooked to the adjustable bolt hole on the leg rack, and at its rear side is an arched hook, so designed that the rear side of the desk plate can be hooked onto the transverse fixing lever or the support ladder that corresponds to the adjustable bolt holes, and the front of the desk plate can be hooked with adjustable hooks to a pair of adjustable bolt holes on the leg rack.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 222 words
A computer desk comprising: a skeleton frame, a desk plate, on each of two sides of the skeleton frame being respectively located a leg rack that is able to rotate freely around a radial shaft lever and a transverse fixing lever to fix a distance between the two radial shaft levers, at each of a front portion of left and right sides of the desk plate being an adjustable bolt hook to be hooked in an adjustable bolt hole on the leg rack, and at a rear portion of the desk plate being an arched hook set to be hooked onto the transverse fixing lever, the arched hook of the desk plate being hooked onto the transverse fixing lever, so the adjustable bolt hook of the desk plate can be hooked in a pair of the adjustable bolt holes on the leg racks, thus to form a computer desk that is conveniently assembled, easily folded, and its height easily adjustable to suit a height of a user, and a telescopic lever extending into the radial shaft lever for adjusting a vertical height of a placement lever by lifting or lowering the telescopic lever and by pushing an inverted U-shaped piece extending into a fixing hole at a back of the radial shaft lever by a catch pin contained inside the telescopic lever.
Claim 2
Dependent Claim 222 words
A computer desk comprising: a skeleton frame, a desk plate, on each of two sides of the skeleton frame being respectively located a leg rack that is able to rotate freely around a radial shaft lever and a transverse fixing lever to fix a distance between the two radial shaft levers, at each of a front portion of left and right sides of the desk plate being an adjustable bolt hook to be hooked in an adjustable bolt hole on the leg rack, and at a rear portion of the desk plate being an arched hook set to be hooked onto the transverse fixing lever, the arched hook of the desk plate being hooked onto the transverse fixing lever, so the adjustable bolt hook of the desk plate can be hooked in a pair of the adjustable bolt holes on the leg racks, thus to form a computer desk that is conveniently assembled, easily folded, and its height easily adjustable to suit a height of a user, and a telescopic lever extending into the radial shaft lever for adjusting a vertical height of a placement lever by lifting or lowering the telescopic lever and by pushing an inverted U-shaped piece extending into a fixing hole at a back of the radial shaft lever by a catch pin contained inside the telescopic lever.
Claim 3
Dependent Claim 54 words
The computer desk, as recited in claim 1, wherein on the transverse fixing lever is at least one support ladder for supporting the rear portion of the desk plate, so as to adjust the height of the desk plate by hooking in the adjustable bolt holes at the front portion of the desk plate.
Claim 4
Dependent Claim 49 words
The computer desk, as recited in claim 1, wherein the arched hook set of the desk plate is a jut or adjustable bolt, so that the arched hook set is easily removed from the transverse fixing lever, after the arched hook set is hooked onto the transverse fixing lever.
