Abstract
Abstract Book lamp structure including a lamp main body, a pivot unit and a base seat. One end of the lamp main body is pivotally connected with the pivot unit. The pivot unit is composed of a connecting member, a supporting rod and a ball joint section disposed on the base seat. One end of the connecting member is axially connected with the lamp main body, while the other end thereof is transversely pivotally connected with the supporting rod, whereby the lamp main body can be rotated about an axis normal to the connecting member and pivotally tilted up and down relative to the supporting rod. The other end of the supporting rod is formed with a spherical section which is pivotally connected with the ball joint of the base seat, whereby the supporting rod as well as the lamp main body can be rotated about the axis of the supporting rod and tilted forward and backward and leftward and rightward and freely universally adjust the angle of the book lamp.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
229 words
A book lamp comprising: a lamp main body having a lamp shade as an illuminating section, one end of the lamp main body being equipped with a socket section; a pivot unit composed of a connecting member, a supporting rod and a ball joint section, one end of the connecting member being formed with a plug section and a pivot section, the plug section being axially inserted into the socket section of the lamp main body such that the lamp main body is rotatable on the pivot section, the pivot section being transversely and pivotally connected with the supporting rod, whereby the lamp main body is rotatable about an axis normal to the connecting member and pivotally tilted up and down relative to the supporting rod; a base seat composed of a housing and a clip member, the housing serving to supply power for the book lamp, the clip member adapted for clipping an article; and one end of the supporting rod of the pivot unit is formed with a spherical section and a ball joint section is disposed on the base seat corresponding to the spherical section by the pivotal connection between the spherical section of the supporting rod and the ball joint section, the supporting rod is rotatable about the axis of the supporting rod and tilted forwards, backwards, leftwards and rightwards relative to the base seat.
Claim 2
Dependent Claim
229 words
A book lamp comprising: a lamp main body having a lamp shade as an illuminating section, one end of the lamp main body being equipped with a socket section; a pivot unit composed of a connecting member, a supporting rod and a ball joint section, one end of the connecting member being formed with a plug section and a pivot section, the plug section being axially inserted into the socket section of the lamp main body such that the lamp main body is rotatable on the pivot section, the pivot section being transversely and pivotally connected with the supporting rod, whereby the lamp main body is rotatable about an axis normal to the connecting member and pivotally tilted up and down relative to the supporting rod; a base seat composed of a housing and a clip member, the housing serving to supply power for the book lamp, the clip member adapted for clipping an article; and one end of the supporting rod of the pivot unit is formed with a spherical section and a ball joint section is disposed on the base seat corresponding to the spherical section by the pivotal connection between the spherical section of the supporting rod and the ball joint section, the supporting rod is rotatable about the axis of the supporting rod and tilted forwards, backwards, leftwards and rightwards relative to the base seat.
Claim 3
Dependent Claim
49 words
A book lamp as claimed in claim 1 , wherein the ball joint section is composed of two concave petal-like halves, the spherical section of the supporting rod being partially clamped by the two concave halves, whereby the supporting rod can be pivotally rotated within the ball joint section.
Claim 4
Dependent Claim
82 words
The book lamp as claimed in claim 1 , wherein the housing defines therein a chamber and is formed with an arch split defined between two laterally expanded arch edges, the arch split having a profile corresponding to the supporting rod and the ball joint section connected therewith, whereby within the arch split, the supporting rod can be rotated about the axis of the supporting rod and tilted forwards, backwards, leftwards and rightwards on the ball joint section of the base seat.
Claim 5
Dependent Claim
21 words
The book lamp as claimed in claim 1 , wherein the housing is formed with a window for mounting a switch.
Claim 6
Dependent Claim
27 words
The book lamp as claimed in claim 1 , wherein a power supply is externally connected with the base seat for supplying power for the book lamp.
