Abstract

A security apparatus for a portable electronic device includes a lock body, an engagement member supported by the lock body, and a lock tip configured to selectively engage the portable electronic device. The lock tip is movable by the engagement member between an engaged position, in which the lock tip is secured to the portable electronic device, and an disengaged position, in which the lock tip is unsecured from the portable electronic device. The lock tip includes a first finger and a second finger that engage the portable electronic device in the engaged position, and a plunger that extends between the first and second fingers and is movable by the engagement member. The plunger includes an engagement feature configured to removably engage the engagement member such that the plunger is selectively removable by a user.

Claims (37)

1 . A security apparatus for a portable electronic device, the security apparatus comprising:

a lock body;

an engagement member supported by the lock body; and

a lock tip configured to selectively engage the portable electronic device, the lock tip movable by the engagement member between an engaged position, in which the lock tip is secured to the portable electronic device, and a disengaged position, in which the lock tip is unsecured from the portable electronic device, the lock tip including a first finger and a second finger that engage the portable electronic device in the engaged position, and a plunger that extends between the first and second fingers and is movable by the engagement member,

wherein the plunger includes an engagement feature configured to removably engage the engagement member such that the plunger is selectively removable by a user, and

wherein the plunger is removable from the lock body without disassembly of the lock body.

2 . The security apparatus of claim 1 , wherein the engagement member includes a user engaging portion configured to be engaged by a user to move the engagement member relative to the lock body.

3 . The security apparatus of claim 2 , wherein the user engaging portion is coupled to a plunger engaging portion of the engagement member, wherein the plunger engaging portion of the engagement member includes an engagement feature configured to removably engage the plunger.

4 . The security apparatus of claim 1 , wherein the plunger is linearly slidable between the engaged position and the disengaged position.

5 . The security apparatus of claim 1 , wherein the plunger is removable from the lock body without removal of the remainder of the lock tip from the lock body.

6 . The security apparatus of claim 1 , wherein the lock body includes a lock mechanism formed as a combination lock mechanism or a keyed lock mechanism.

7 . The security apparatus of claim 1 , wherein the plunger is a first plunger and is replaceable by a second plunger having a decreased width relative to the first plunger such that the first and second fingers are spaced apart from one another by a first distance when the first plunger is in the engaged position and by a second distance, less than the first distance, when the second plunger is in the engaged position.

8 . A security apparatus configured to interchangeably engage a slot of a first portable electronic device and a slot of a second portable electronic device, the security apparatus comprising:

a lock body;

an engagement member supported by the lock body; and

a lock tip configured to selectively engage the portable electronic device, the lock tip movable by the engagement member between an engaged position, in which the lock tip is secured to the portable electronic device, and a disengaged position, in which the lock tip is unsecured from the portable electronic device, the lock tip including a first finger and a second finger that engage the portable electronic device in the engaged position and an interchangeable first plunger and second plunger,

wherein the first plunger is configured to create a gap of a first width when installed between the first and second fingers and in the engaged position, and

wherein the second plunger creates a gap of a second width when installed between the first and second fingers and in the engaged position, wherein the second width is less than the first width.

9 . The security apparatus of claim 8 , wherein the engagement member includes a user engaging portion configured to be engaged by a user to move the engagement member relative to the lock body.

10 . The security apparatus of claim 9 , wherein the user engaging portion is coupled to a plunger engaging portion of the engagement member, wherein the plunger engaging portion of the engagement member includes an engagement feature configured to separately engage the first plunger and the second plunger.

11 . The security apparatus of claim 8 , wherein the first plunger is linearly slidable between the engaged position and the disengaged position.

12 . The security apparatus of claim 11 , wherein the second plunger is linearly slidable between the engaged position and the disengaged position.

13 . The security apparatus of claim 8 , wherein each plunger of the first plunger and the second plunger is removable from the lock body without disassembly of the lock body.

14 . The security apparatus of claim 8 , wherein each plunger of the first plunger and the second plunger is removable from the lock body without removal of the remainder of the lock tip from the lock body.

15 . The security apparatus of claim 8 , wherein the lock body includes a lock mechanism formed as a combination lock mechanism or a keyed lock mechanism.

16 . A method of modifying a security apparatus comprising:

axially removing a first plunger from between a first finger and a second finger of the security apparatus; and

axially inserting a second plunger dissimilar from the first plunger between the first and second fingers.

17 . The method of claim 16 , wherein axially removing the first plunger includes disengaging an engagement feature of the first plunger from an engagement member.

18 . The method of claim 17 , wherein axially inserting the second plunger between the first and second plungers includes engaging an engagement feature of the second plunger with the engagement member.

19 . The method of claim 16 , wherein axially removing the first plunger includes engaging opposing sides of the first plunger with a tool.

20 . A security apparatus for a portable electronic device, the security apparatus comprising:

a lock body;

an engagement member supported by the lock body; and

a lock tip configured to selectively engage the portable electronic device, the lock tip movable by the engagement member between an engaged position, in which the lock tip is secured to the portable electronic device, and a disengaged position, in which the lock tip is unsecured from the portable electronic device, the lock tip including a first finger and a second finger that engage the portable electronic device in the engaged position, and a plunger that extends between the first and second fingers and is movable by the engagement member,

wherein the plunger includes an engagement feature configured to removably engage the engagement member such that the plunger is selectively removable by a user, and

wherein the plunger is removable from the lock body without removal of the remainder of the lock tip from the lock body.
