Specification No. 5 discloses this type of fastener, which has a threaded engagement protrusion formed in the hole of the main body member, and the legs of the main body member can be expanded by inserting the threaded member in the axial direction. It can be removed by rotating the member. In such known examples, the main body member of the fastener and the screw member are joined together before use. However, in such known examples, the screw engaging protrusion formed to engage with the screw member is small in size and shape, and cannot strongly connect the main body member and the screw member. The bonding strength between the two panels is also small. As a result, there is the disadvantage that relatively small axial forces cause the two panels to move apart from each other.

に拡開。It is an object of the present invention to provide a reusable two-piece fastener for releasably joining a plurality of panels. The two-piece fastener consists of a body member and an associated threaded member having external threads. The body member is molded from a resilient, compressible, flexible plastic and has a flange at one end of its shank and radially flares at the other end.

ねじを越えて押し込む。この結果脚が拡開しパネルがこ
の拡開された脚とフランジ間に挟持されるようになる。It has collapsible legs, which are separated from each other by a longitudinal groove and whose free ends are connected to each other by a flexible connection. A cylindrical shaft hole is formed inward from the flange of the main body member toward the shaft portion, and an inclined surface for expansion and expansion is formed on the inner surface of the zero leg communicating with the groove. An internal thread is formed in the inner wall of the shaft hole, and this internal thread can be expanded from an initial state due to its compressibility or by the outward expansion of the legs. The internal thread is formed by axially spaced internal threads along the bore, each internal thread having a circumferential discontinuity. The screw member includes a screw shaft portion and a male thread formed on the screw shaft portion. In use, insert the shaft of the main body member into the hole in the panel so that its flange touches one panel.Next, without rotating the screw member in the axial direction, insert the shaft part of the main body member into the hole in the main body member beyond the female thread. and push it in. As a result, the legs are expanded and the panel is held between the expanded legs and the flange.

After the screw member is inserted, the female screw returns to its initial state and comes to engage with the male screw of the screw member, so that the screw member cannot be removed from the main body member unless it is rotated.

出し得るようになる。That is, the threaded member can only be removed from the body member by reverse rotation, in which case the male thread cooperates with the female thread in the normal manner. Preferably, a discontinuous portion is formed in the external thread to prevent the threaded member from completely disengaging from the shaft hole of the main body member. When the screw member is rotated and pulled out, the legs are in an unexpanded state and the main body member can be pulled out from the hole in the panel.

等のおそれがない。The female thread formed in the shaft hole of the main body member is flexible and allows the threaded member to be inserted into it in the axial direction, but when the threaded member is pulled out, the threaded member is resisted unless the threaded member is rotated. Further, unlike the known example, the female thread formed in the shaft hole of the main body member is sufficiently large and can be reliably engaged with the male thread, so that even if a pull-out force is applied to the male thread, the two will not come apart unnecessarily. In addition, the main body member can be formed using conventional molding techniques without compromising strength or other properties.Furthermore, a discontinuous portion is provided on the male thread to prevent the two from completely separating when the threaded member is rotated and pulled out from the main body member. There is no fear that one of them will be lost and cannot be reused.
