Abstract: The present invention pertains fasteners with critical configuration of the barbs, which allows the fasteners to be used in slots of various widths and panels of various thicknesses, and prevents rattling, which would take place in the case of fasteners of the present state of the art. The critical configuration is based on the special dimensions and special shape of the barbs with regard to the parts and the slots involved in assemblies of the fasteners and the parts. The present invention also pertains assemblies of miscellaneous parts connected together by means of the fasteners, as well as vehicles comprising such assemblies. In addition, the present invention comprises fasteners providing a combination of low barbs and high bent barbs, which combination prevents rattling of the fastener and allows secure attachment on a part, such as a sheet metal, for example.

Abstract: A spring fastener characterized by a structure having a cavity in which the rib of a first part, such as a plastic panel for example, like a pillar, may be engaged, and is also suitable to be engaged reversibly in a slot of second part, such as a metal sheet for example, like the frame of a car. The spring fastener comprises engagement springs having a peak, engagement regions and-side cuts in the vicinity of the peak, preferably within the engagement regions. The side-cuts, of preferably triangular shape, increase considerably the lever/angle pulling force (pulling force applied on the first part and away from the spring fastener, in order to separate the first part from a second part connected together with the spring fastener). It is highly preferable that the fastener comprises barbs with inwardly bent front ends, and that the engagement regions further have hindrance portions, the combination of which highly improves the balance of insertion to removal ratio.

Abstract: A Spring fastener with critical configuration of the barbs, which allow the extraction of the fastener without destruction of the slot and/or the fastener. This critical configuration of the barbs allows spring fasteners to be used in slots of various widths and prevents rattling, which would take place in the case of spring fasteners of the present state of the art. The critical configuration is based on the special dimensions and special shape of the barbs with regard to the parts and the slots involved in assemblies of the spring fasteners and the parts. Assemblies of miscellaneous parts connected together by means of such spring fasteners, as well as vehicles comprising such assemblies may be made.

Abstract: A fastener having a head and two expandable legs. The fastener further has a Y-shaped funnel configuration, which has been formed by a partial cut of the legs. The sides of the Y-shaped funnel comprise inwardly bent portions which are designed to extend into the slot of an object. The bent portions produce jamming and clamping when an expanding member is inserted through a hole on the head, resulting to highly improved pulling force. The fastener may be used in slots of different widths and may be pulled easily out of the slots, if so desired, in contrast with the fasteners of the present state in the art. Further, the fastener may be used in vehicles to connect one or more parts together.

Abstract: This invention is related to a screw-nail member, to anchoring devices, articles using the anchoring devices to be secured on each other, and vehicles comprising one or more of the above. The screw-nail member has a first head, a screw upper portion toward the first head, and a leading nail lower portion away from the head. The screw-nail member may be used with conjunction with a spring fastener having a second head and two legs. The leading nail lower portion expands the legs of the fastener for securing a first object on a second object before the upper screw portion engages on the upper side of the second head of the fastener. This eliminates bowing of the head, which occurs when conventional screws or bolts are used with the fastener. In addition, engagement requires only push-in action with minimal turning of the screw-nail member, thus considerably improving productivity.

Abstract: This invention pertains fasteners, and more particularly fasteners which have expandable legs and which attach one object to another object. It also pertains combinations of one or more objects with said fastener(s), parts or objects connected with the fastener(s), as well as vehicles comprising parts connected with said fastener(s). The fastener comprises a substantially flat head and two expandable legs. The head preferably has an upper side and a lower side, preferably separated by a gap. The head also has a hole (round, oblong or otherwise shaped) in which the expanding body may engage or pass through for expanding the legs and securing a first object having a slot to a second object having a hole, such as a metal sheet to a plastic panel, for example. The fastener also comprises a Y-shaped funnel configuration, which has been formed by a partial cut of the legs. The sides of the Y-shaped funnel comprise inwardly bent portions which are designed to extend into the slot of the first object.

Abstract: This invention relates to a fastener, which expands by the insertion of an expanding member, preferably a screw. The fastener comprises a substantially flat head and two expandable legs. The head has an upper side and a lower side, preferably separated by a gap. The head also has a hole (round, oblong or otherwise shaped) in which the expanding body may engage or pass through for expanding the legs and securing one object to another object, such as a plastic panel to a metal sheet. The fastener also comprises a Y-shaped funnel configuration, which has been formed by a partial cut of the legs. Miscellaneous configurations of the Y shaped legs provide improved guidance to the expanding member, improved engagement to at least one of the objects, such as the metal sheet for example, and improved engagement to the expanding member, among other advantages. The fastener may also comprise portions under the upper side of the head, which portions are engageable to the expanding member.

Abstract: This invention relates to a fastener, which expands by the insertion of an expanding member, preferably a screw through an engageable hole of the fastener. The fastener comprises a substantially flat head and two expandable legs. The head has an upper side and a lower side, preferably separated by a gap. The fastener has a hardness within a range which improves considerably the pulling force and allows the head of the fastener to be bowable upon applying said force on the expanding member, thus resulting in a gradual rather than abrupt failure. The engageable hole may be round or oblong. Additional engagement may be provided at lower portions of the fastener for improving pulling force and/or prevailing torque. Further, an elastic body may be integrally molded at least at the lower side of the head of the fastener, and preferably throughout the head of the fastener.

The head has an upper side and a lower side, preferably separated by a gap. The head also has an oblong hole in which the expanding body engages for securing one object to another object. The oblong hole represents a plurality of regular generally round holes, so that it becomes easy for the fastener to be located in difficult positions of the objects to be connected. The oblong hole has sides on different planes, and each side has an edge. Preferably, at least one of the two edges contains arcs for better guidance of the expanding member. Additional engagement may be provided at lower portions of the fastener for improving pulling force and/or prevailing torque. Further, an elastic body may be integrally molded at least at the lower side of the head of the fastener, and preferably throughout the head of the fastener.
