This disclosure relates generally to security devices designed to protect merchandise from theft. More specifically, the disclosed technology pertains to a security tag for securing footwear, particularly shoes with upper straps, such as sandals or slippers, collectively referred to as slide shoes. The innovative design of this security tag aims to address the shortcomings of traditional pin-based and cable-based security tags by minimizing damage to the merchandise and enhancing the comfort and convenience for customers trying on the products in-store.
Retail stores commonly use security tags to prevent the theft of shoes and other merchandise with straps. There are two prevalent types of security tags: pin-based tags and cable-based tags, illustrated in
Pin-based tags involve a separate pin that is inserted through a part of the shoe, such as the strap or upper of a sandal or slipper, and then locked into the tag.
Store personnel must use a special tool to remove the pin to unlock the shoe. These tags often include electronic circuits or alarms that trigger if someone attempts to improperly remove the pin or take the shoes out of the store while still tagged. However, pin-based tags can potentially damage the shoe's material, especially when the shoe is made of delicate materials such as leather, synthetic fabrics, rubber, PVC, or canvas. Additionally, the pins can be easily lost, posing safety hazards, with reported incidents of customers being injured by loose pins in stores.
Cable-based tags utilize a cable that wraps around a portion of the shoe, such as the strap or upper of a sandal or slipper, and then plugs into the tag similar to pin-based tags, a special tool is required to unplug the cable from the tag to unlock the shoe. These tags often contain an alarm chip as well. The rigid material of the cable, typically metal or hard plastic, provides security but does not conform to the shoe's shape. This rigidity can cause pressure points or friction against the customer's foot when trying on the shoe, leading to discomfort and an unnatural fit. This can make it difficult for customers to assess the true comfort and feel of the shoes, potentially affecting their purchase decision.
Both types of traditional security tags present significant disadvantages, either by risking damage to the merchandise or by detracting from the customer's shopping experience. This has created a need for a more effective and customer-friendly solution.
According to various embodiments of the disclosed technology, this application describes a clamp device or a shoe tag specifically designed for sandals or slippers, or other suitable types of shoes having an upper strap. These shoes are collectively called slide shoes for simplicity. This shoe tag avoids damaging the material of the shoes and makes it more comfortable for customers to try on.
In some embodiments, the clamp device may include a bottom piece, a left piece, a right piece, and a top piece. The top piece is further divided into a first top sub-piece and a second top sub-piece, each covering a portion of the top side of the clamp device. 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 for receiving the head of the second top sub-piece, allowing the two sub-pieces to engage and lock securely when the head rotates into the cavity.
In some embodiments, the bottom piece, left piece, and first top sub-piece are fixed together, while the right piece and second top sub-piece are fixed together. The right piece is rotatably mounted to the bottom piece, acting as a rotating shaft that facilitates the rotational movement of the second top sub-piece.
In some embodiments, the cavity on the first top sub-piece includes a protruding tip positioned on the ceiling or floor of the cavity. The head of the second top sub-piece has a corresponding hole, which aligns with the protruding tip to securely hold the sub-pieces together when engaged. Additionally, the cavity may contain a spring installed on the inner wall facing the cavity's opening. This spring generates a counterforce to help pop the head of the second top sub-piece out of the cavity upon unlocking.
In some embodiments, for enhanced security, the first top sub-piece can include an ink container that holds ink, configured to leak if the sub-pieces are disengaged improperly, indicating tampering. In another version, a fake ink container appears to hold colored liquid for visual deterrence. The head of the second top sub-piece may also include a notch to receive the spring installed in the cavity during engagement.
In some embodiments, the right piece is mounted to the bottom piece via a hinge, allowing the right piece and second top sub-piece to rotate toward and away from the first top sub-piece. A magnetic lock mechanism can be included, where a magnetic key interacts with a magnetic lock house to retract or lift the protruding tip, unlocking the sub-pieces.
In some embodiments, the clamp device can be integrally formed as two units: one comprising the bottom piece, left piece, and first top sub-piece, and the other comprising the right piece and second top sub-piece. The device ensures precise alignment of the sub-pieces for secure engagement. The bottom piece, left piece, right piece, and top pieces form a hollow center, designed to receive straps of shoes or other products with straps.
In summary, the clamp device offers a robust and versatile clamping solution with features ensuring secure engagement, tamper evidence, and ease of use. Its design caters to various applications, making it suitable for use in products requiring secure clamping mechanisms.
The present invention provides an improved security tag specifically designed for shoes with straps, such as sandals or slippers, collectively referred to as slide shoes. This innovative shoe tag addresses the shortcomings of traditional pin-based and cable-based security tags by minimizing damage to the shoe materials and enhancing comfort for customers.
The depicted shoe tag is designed as a clamp device (referred to as “clamp” in the following description for simplicity) specifically for securing shoes with straps. The shoe tag features a hollow center and four main sides: a bottom piece 201, a left piece 202, a right piece 208, and a top piece. The absence of a front or rear piece creates the hollow center. The top piece is divided into two sub-pieces: a first top sub-piece 203 and a second top sub-piece 207, each covering a portion of the top side of the clamp. The bottom piece 201, left piece 202, and first top sub-piece 203 are fixed together, while the right piece 208 and second top sub-piece 207 are fixed together.
The right piece 208 is rotatably mounted to the right end of the bottom piece 201, acting as the rotating shaft. For instance, the right piece 208 may include a hinge 211 that facilitates rotation. During this rotation, the second top sub-piece 207 also rotates due to its fixed connection with the right piece 208. The second top sub-piece 207 can rotate toward the first top sub-piece 203 to engage and lock, or away from first top sub-piece 203 to create an opening for receiving shoe straps or other materials, thereby locking them in place by engaging with the first top sub-piece 203.
The first top sub-piece 203 includes an end with a cavity 214, a recessed area within the clamp. Inside this cavity 214, there is a retractable or liftable protruding tip 205 located either on the ceiling or floor of the cavity. This protruding tip can be pulled back or lifted using a magnetic force, such as a magnetic key.
The second top sub-piece 207 has an end with a thin head 206 designed to fit into the cavity 214 of the first top sub-piece 203. When the second top sub-piece 207 rotates toward the first top sub-piece 203, the two sub-pieces engage, and the thin head 206 of the second top sub-piece 207 enters the cavity 214 of the first top sub-piece 203, creating a locked state. The protruding tip 205 within the cavity 214 aligns with a hole 212 on the thin head 206 of the second top sub-piece 207, securely holding the two sub-pieces together.
Within the cavity 214, a spring 204 is installed on the inner wall, facing the opening of the cavity 214. When the two sub-pieces are engaged, the thin head 206 of the second top sub-piece 207 applies pressure to the spring 204, compressing it against the inner wall of the cavity 214. This compression generates a counterforce on the thin head 206, exerted by the spring 204.
The force from the spring 204 remains as long as the protruding tip 205 in the cavity 214 maintains the lock on the second top sub-piece 207. To unlock the two sub-pieces, a special device or key can be used to retract or lift the protruding tip 205 within the cavity 214, for example, by tapping on the magnetic lock house 209. This action releases the thin head 206 of the second top sub-piece 207, allowing the pushing force from the spring 204 within the cavity 214 to push the thin head 206 out of the cavity 214.
This pushing force assists store personnel in opening the clamp.
This mechanism ensures a secure connection between the two top sub-pieces, with the protruding tip 205 and the spring 204 working together to maintain the lock and facilitate the release of the clamp for attaching shoe straps or other materials.
Additionally, the first top sub-piece 203 may include an ink container 213. The ink leaks from the ink container 213 when the clamp is tampered with or forcibly opened (e.g., disengaging the first top sub-piece 203 and the second top sub-piece 207 without a proper unlocking mechanism). In an alternative embodiment, the ink container may be a decoy that appears to hold colored liquid, designed to deter potential thieves by making them think that the container will leak ink if tampered with.
The thin head 206 on the second top sub-piece 207 may have a notch 210, which receives the spring 204 in the cavity 214 when engaging with the first top sub-piece 203.
The first top sub-piece 4 and the second top sub-piece 3 are designed to engage with each other to form a secure lock. The engagement occurs when the second top sub-piece 3 rotates towards the first top sub-piece 4. The rotation allows the thin head 3.1 of the second top sub-piece 3 to fit snugly into the cavity 4.1 of the first top sub-piece 4.
The thin head 3.1 is a critical part of the locking mechanism. It is specifically designed to align with and enter the cavity 4.1, ensuring a secure fit. Within the cavity 4.1, there is a protruding tip (identified as 205 in
This locking mechanism ensures that the shoe tag remains securely fastened until it is intentionally unlocked using the appropriate tool or key. The detailed design of the thin head and cavity, along with the engagement of the protruding tip, provides a robust and reliable security solution for protecting shoes with straps from theft.
Other embodiments can be contemplated based on the description above. For example, the right side piece may be fixed to the bottom piece, and the second top sub-piece may be rotatably mounted to the top of the right side piece.
