Abstract

Abstract An apparatus for locking a notebook computer on a computer support includes a padlock, an elongated fixing member fastening the padlock to the computer support, and a lock support fastening the padlock to the computer. The computer housing of the computer is of the type having a straight slot and a threaded hole which are formed in the outer surface thereof, and is provided with a built-in bolt member which is engaged within the threaded hole. The lock support has a counterbore through which the bolt member extends. A rib projects from the lock support to engage within the slot of the computer housing so as to prevent rotation of the lock support relative to the computer housing. A shackle hole is formed through the lock support in such a manner that the counterbore and the shackle hole intersect. The shackle of the padlock extends through the shackle hole and covers the head of the bolt member so as to prevent a screwdriver from access to the bolt member.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 290 words
A lock support for fastening a padlock to a notebook computer, the notebook computer including an outer surface having a straight slot and a threaded hole that are formed therein, and a bolt member engaged threadably within the threaded hole and having a head and a threaded stem, the head of the bolt member having a recess portion which can be rotated by a screwdriver so as to remove said lock support from the notebook computer, the padlock having a lock body and a shackle mounted movably on the lock body, said lock support comprising a counterbore and a shackle hole which are formed therethrough and which intersect each other, said counterbore having a small-diameter portion and a large-diameter portion, the threaded stem of the bolt member extending through said small-diameter portion of said lock support, the head of the bolt member being located within said large-diameter portion of said lock support and having a diameter greater than that of said small-diameter portion of said counterbore so as to fasten said lock support to the notebook computer, said lock support further including a straight rib projecting therefrom to engage within the slot of the notebook computer so as to prevent rotation of said lock support relative to the notebook computer, the shackle of the padlock being capable of being inserted through said shackle hole of said lock support and of being locked within the lock body of the padlock so as to cover the recess portion of the bolt member, thereby preventing a screwdriver from access to the bolt member, whereby, when the padlock is locked on said lock support, said lock support cannot be removed from the notebook computer unless an associated key is used to open the padlock.
Claim 2
Dependent Claim 290 words
A lock support for fastening a padlock to a notebook computer, the notebook computer including an outer surface having a straight slot and a threaded hole that are formed therein, and a bolt member engaged threadably within the threaded hole and having a head and a threaded stem, the head of the bolt member having a recess portion which can be rotated by a screwdriver so as to remove said lock support from the notebook computer, the padlock having a lock body and a shackle mounted movably on the lock body, said lock support comprising a counterbore and a shackle hole which are formed therethrough and which intersect each other, said counterbore having a small-diameter portion and a large-diameter portion, the threaded stem of the bolt member extending through said small-diameter portion of said lock support, the head of the bolt member being located within said large-diameter portion of said lock support and having a diameter greater than that of said small-diameter portion of said counterbore so as to fasten said lock support to the notebook computer, said lock support further including a straight rib projecting therefrom to engage within the slot of the notebook computer so as to prevent rotation of said lock support relative to the notebook computer, the shackle of the padlock being capable of being inserted through said shackle hole of said lock support and of being locked within the lock body of the padlock so as to cover the recess portion of the bolt member, thereby preventing a screwdriver from access to the bolt member, whereby, when the padlock is locked on said lock support, said lock support cannot be removed from the notebook computer unless an associated key is used to open the padlock.
Claim 3
Independent Claim 319 words
An apparatus for locking a notebook computer on a computer support, the computer having a computer housing which has a straight slot and a threaded hole that are formed in an outer surface of the housing, and a bolt member engaged threadably within the threaded hole of the housing and having a head and a threaded stem, the head of the bolt member having a recess portion which can be rotated by a screwdriver, said apparatus comprising: a lock support having a counterbore and a shackle hole which are formed therethrough and which intersect each other, said counterbore having a small-diameter portion and a large-diameter portion, the threaded stem of the bolt member extending through said small diameter portion of said lock support, the head of the bolt member being located within said large-diameter portion of said lock support and having a diameter greater than that of said small-diameter portion of said counterbore so as to fasten said lock support to the computer housing, said lock support further including a straight rib projecting therefrom to engage within the slot of the computer housing so as to prevent rotation of said lock support relative to the computer housing; a padlock having a lock body and a shackle having two end portions which are locked within said lock body, said shackle extending through said shackle hole of said lock support and covering the recess portion of the bolt member so as to prevent the bolt member from being driven by the screwdriver; and an elongated flexible fixing member fastened to said padlock at one end portion thereof and to the computer support at the other end portion thereof; whereby, when said padlock is opened by an associated key, said padlock can be removed from said lock support so as to permit the screwdriver to access the recess portion of the bolt member, thereby removing said lock support from the computer housing.
Claim 4
Independent Claim 319 words
An apparatus for locking a notebook computer on a computer support, the computer having a computer housing which has a straight slot and a threaded hole that are formed in an outer surface of the housing, and a bolt member engaged threadably within the threaded hole of the housing and having a head and a threaded stem, the head of the bolt member having a recess portion which can be rotated by a screwdriver, said apparatus comprising: a lock support having a counterbore and a shackle hole which are formed therethrough and which intersect each other, said counterbore having a small-diameter portion and a large-diameter portion, the threaded stem of the bolt member extending through said small diameter portion of said lock support, the head of the bolt member being located within said large-diameter portion of said lock support and having a diameter greater than that of said small-diameter portion of said counterbore so as to fasten said lock support to the computer housing, said lock support further including a straight rib projecting therefrom to engage within the slot of the computer housing so as to prevent rotation of said lock support relative to the computer housing; a padlock having a lock body and a shackle having two end portions which are locked within said lock body, said shackle extending through said shackle hole of said lock support and covering the recess portion of the bolt member so as to prevent the bolt member from being driven by the screwdriver; and an elongated flexible fixing member fastened to said padlock at one end portion thereof and to the computer support at the other end portion thereof; whereby, when said padlock is opened by an associated key, said padlock can be removed from said lock support so as to permit the screwdriver to access the recess portion of the bolt member, thereby removing said lock support from the computer housing.
Claim 5
Dependent Claim 23 words
An apparatus as claimed in claim 2 wherein said fixing member includes a metal chain having an end ring sleeved on said shackle.
