  • Patent number: 10219587
    Abstract: An attachment system is formed by a primary device and a secondary device connected to the primary device in a pivoting manner. The primary device has a main body, two lateral sides and a bar for attaching the primary device to another object. Each of the lateral sides has a protrusion extending laterally outward from the lateral sides. The secondary device has two lateral sides, each equipped with an aperture that corresponds to one of the protrusions on the primary device, so that fitting the protrusions into the apertures pivotally connects the primary device to the secondary device, with the lateral sides of the secondary device being disposed outside of the lateral sides of the primary device. The secondary device can be pivoted between a folded position where the secondary device lies against the primary device, and an open position where the secondary device is raised up.

  • Publication number: 20180368533
    Abstract: An attachment assembly has a hook component and a bracket component to which the hook component is removably attached. The hook component has a base body, a hook element attached to the base body, an attachment device for attaching an item to the hook component, and a first magnet connected to the hook element. The bracket component has a base surface, a front surface, and a hook-supporting strut between the base surface and the front surface. The bracket component has a second magnet connected to the base surface. Inserting the hook element in a space between the base surface and the front surface causes the magnets to attract each other and force the hook element through the space to rest on the hook-supporting strut.

  • Patent number: 10130148
    Abstract: A snap button has a female portion formed from a cap and a socket that are connected together with a piece of fabric in between. The cap is formed from a base body having a circumferential flange with interruptions therein so that the flange can be bent outward during assembly. The socket is formed by a disc having a central aperture and a peripheral rim, as well as an annular insert disposed within the socket. The cap is connected to the socket by pressing the socket onto the cap until the flange bends around the annular insert to anchor the cap to the socket with the fabric trapped between. A male portion having a stud is connected to the female portion by snapping the stud into the socket such that the stud extends entirely through the socket and into the cap.

  • Patent number: 9877550
    Abstract: A pull tab is formed by a cord having a cord retaining member at one end and a plug at the other end. The plug has a flap connected to one end, the flap having an open position where the flap is connected to the plug only at one end of the flap, and a closed position where the entire flap is secured to the plug. The cord retaining member has first and second channels therethrough, with the second channel being larger than the first channel. When the flap is open, the plug fits though both the first and second channels, and when the flap is closed, the plug fits only within the second channel. The pull tab is assembled by feeding the plug through the channels, moving the flap to the closed position and pulling the plug back through the second channel until the plug is seated in the second channel.

  • Patent number: 9862143
    Abstract: A pull tab for zippers is formed by a cord having a cord retaining member attached to one end of the cord and a plug attached to other end of the cord. The cord retaining member has an internal cavity, a first aperture on a proximal end next to the cord and a second aperture on a distal end. The cavity and first and second apertures are sized so that when the cord is wrapped around the plug, the plug fits through the second aperture and cavity but does not fit through the first aperture. The pull tab is assembled by feeding the plug through a zipper tab and then the first aperture, the cavity and the second aperture, wrapping the cord around the plug, and pulling the cord to force the plug with the cord wrapping back into the cavity.

  • Patent number: 9669572
    Abstract: A molding process for creating a decorative pull has two separate molding steps. In the first molding step, a first top mold portion, and a bottom mold portion are used. The bottom mold portion has a mold compartment with an indentation in the bottom. An end of a soft string is placed in this compartment with the end disposed over the indentation. The first top mold portion is closed over the bottom mold portion and molding material is injected. The molding material enters the mold cavity and flows into the indentation to cover the ends of the string entirely, to create a first molded component. A second top mold portion is then placed over the bottom mold potion and molding material is then injected into the second mold cavity formed by the second top mold portion to cover the first molded component and create a molded pull for use on zippers or other items.

  • Patent number: 9630280
    Abstract: A method for producing a single-sided mold and a double-sided coining mold are provided. The method comprises the following steps: S1. forming a mold cavity on the single-sided mold according to shape of a product; S2. engraving a surface of the mold cavity by a first engraving and milling cutter to form engraved holes, and then inserting a second engraving and milling cutter into the engraved holes for further engraving to form holes to be coined; S3. repeating the step S2 until a predefined number of the holes to be coined are formed on the surface of the mold cavity; S4. placing a coining die with hardened tips on the surface of the mold cavity, and embedding each of the hardened tips into one of the holes to be coined respectively, and then the mold cavity being molded by a coining process.

  • Patent number: 9498027
    Abstract: A pull tab for zippers is formed by a cord having a cord retaining member attached to one end of the cord and a socket in the top surface of the cord retaining member, and a plug attached to other end of the cord. The plug has a shape corresponding to the shape of the socket, so that the plug can fit securely within the socket, thus, forming a loop with the cord. A slidable locking device is placed around the cord, the locking device having an interior cavity corresponding to the shape of the cord retaining member, such that placing the plug into the socket and sliding the locking device over the cord retaining member locks the second end of the cord to the cord retaining member. In a method for manufacturing the pull tab, the plug and cord retaining member are continuously overmolded in one piece on a length of the cord, and then cut into pieces to form completed pull tabs.

  • Patent number: 9307808
    Abstract: A buckle assembly has male and female portions with magnets embedded in each portion. The male portion has a locking leg with a pawl at its end that seats within a corresponding locking groove having an insertion portion and a locking portion having a flange on the female portion when the male and female portions are placed together. When the male part is placed adjacent the female part, the magnets attract each other to force the locking leg through the insertion portion of the locking groove. The magnets are disposed laterally offset from each other when the locking leg extends through the insertion portion, so that the magnets to pull the male and female portions in opposing lateral directions to force the locking leg into the locking portion of the groove, causing the locking pawl to engage the flange and lock the male portion to the female portion.
