Abstract

This disclosure describes a clamp device designed to secure items with straps, such as sandals or slippers, providing enhanced security and ease of use. The clamp device comprises a bottom piece, a left piece, a right piece, and a top piece, wherein the top piece is divided into a first top sub-piece and a second top sub-piece. The first top sub-piece is fixed, while the second top sub-piece is configured to rotate toward or away from the first top sub-piece. The first top sub-piece includes a cavity designed to receive the head of the second top sub-piece. Engagement and locking occur when the head of the second top sub-piece rotates into the cavity of the first top sub-piece, securing the device. This design minimizes damage to the shoe materials and enhances comfort for customers, providing a more secure and customer-friendly solution for protecting merchandise from theft.

3 . The clamp device of claim 2 , further comprising a magnetic lock house, wherein the protruding tip is retractable or liftable using a magnetic key that interacts with the magnetic lock house to unlock the first top sub-piece from the second top sub-piece.

4 . The clamp device of claim 1 , wherein:

the cavity on the first top sub-piece comprises a spring installed on an inner wall of the cavity, facing an opening of the cavity, and

the spring is configured to generate a counterforce when the head of the second top sub-piece rotates into the cavity of the first top sub-piece and is locked therein, and to help pop the head of the second top sub-piece out of the cavity upon unlocking.

5 . The clamp device of claim 1 , wherein:

the first top sub-piece comprises an ink container that holds ink, and the ink container is configured to leak the ink when the first top sub-piece and the second top sub-piece are disengaged improperly.

6 . The clamp device of claim 5 , wherein the first top sub-piece and the second top sub-piece are disengaged improperly when the first top sub-piece and the second top sub-piece are tampered with or forcibly disengaged without using an unlocking mechanism.

7 . The clamp device of claim 1 , wherein:

the first top sub-piece comprises an ink container that appears to hold colored liquid.

8 . The clamp device of claim 1 , wherein:

the head of the second top sub-piece comprises a notch, configured to receive a spring installed in the cavity when the first top sub-piece engages with the second top sub-piece.

9 . The clamp device of claim 1 , wherein the bottom piece, the left piece, and the first top sub-piece are integrally formed as a single unit, and the right piece and the second top sub-piece are integrally formed as another single unit.

10 . The clamp device of claim 1 , wherein the bottom piece, the left piece, the right piece, and the top piece form a hollow center.

11 . The clamp device of claim 10 , wherein the hollow center is configured to receive straps of shoes or other products with straps.

12 . A clamp device, comprising:

a bottom piece, a left piece, a right piece, and a top piece,

the top piece comprising a first top sub-piece and a second top sub-piece, each covering a portion of a top side of the clamp device,

wherein:

the first top sub-piece is fixed and the second top sub-piece is configured to rotate away from or toward the first top sub-piece;

the first top sub-piece comprises a cavity for receiving a head of the second top sub-piece;

the first top sub-piece and the second top sub-piece are engaged and locked when the head of the second top sub-piece rotates into the cavity of the first top sub-piece; and

the first top sub-piece comprises an ink container that appears to hold colored liquid.

13 . The clamp device of claim 12 , wherein:

the cavity on the first top sub-piece comprises a protruding tip positioned on a ceiling or a floor of the cavity,

the head of the second top sub-piece comprises a hole, and

when the head of the second top sub-piece rotates into the cavity of the first top sub-piece, the protruding tip aligns with the hole on the head to securely hold the first top sub-piece and the second top sub-piece together.

14 . The clamp device of claim 13 , further comprising a magnetic lock housing, wherein the protruding tip is retractable or liftable using a magnetic key that interacts with the magnetic lock housing to unlock the first top sub-piece from the second top sub-piece.

15 . The clamp device of claim 12 , wherein:

the cavity on the first top sub-piece comprises a spring installed on an inner wall of the cavity, facing an opening of the cavity, and

the spring is configured to generate a counterforce when the head of the second top sub-piece rotates into the cavity of the first top sub-piece and is locked therein, and to help pop the head of the second top sub-piece out of the cavity upon unlocking.

16 . The clamp device of claim 12 , wherein:
