Detailed description As shown in FIG. 1, a fastening method according to a preferred embodiment of the present invention is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm). 6 V. Description of the invention (including -Generally cylindrical head 12 and-shaft 14, the latter is heart-shaped: the cylindrical head 12 is coaxial and extends from a long end of the head 12 to the wide head U, preferably with resilience The material is spray-casted on the shaft 14. When bran is used, it is known that the use of the "dagger" is a well-known measure, such as an adhesive or a mechanical connection, to firmly attach the head 12 to the shaft ... It is within the scope of the present invention. The shaft Η preferably has a tip 16 and a screw, and the ㈣ is arranged on the straight, so that the fastener 10 can be screwed into a vertical support by a screw. Η 最Good thing-the ergonomic grasping element becomes the _ annular recessed portion: 9 is close to the shaft, so that a user can comfortably and stably by putting his thumb and index finger into the recess ^ 19 Grasp the head 12. The resilient material of the head p, combined with its ergonomic shape, uniquely makes this This fastener 10 can be grasped and driven into a vertical support (wall) without tools by hand. This grasping can also help increase stability when pushing the push pin into the support. Although the use of the thread 18 is not necessary, the thread 18 can make the fastener 10 more easily pushed by the user (twisting the fastener manually) into the vertical support, and once installed, the Additional surface area may be provided to retain the fastener in the vertical support. The head 12 also includes a generally straight longitudinal end surface 20, suitable for abutting against a wall or a vertical support. A flat surface and includes a plurality of resilient resilient projections 22 distributed along the axial direction from the other longitudinal end 24 of the head. As shown in FIG. 2, once the fastener 10 has been driven Into a support 26 1222497 A7 _______B7 V. Description of the invention (7 ~~--'The ring-shaped protrusion 22 is ready to be used to install an object 28 to the support%. The object 28 includes a stretched into the object Hole in a generally straight end surface 32 The hole or groove 30 ′, wherein the hole or groove 30 includes the lower wall 34, 36, and the distance between the upper and lower walls 34, 36 is slightly smaller than the diameter of the fastener protrusion 22, Therefore, when the hole 12 and the groove 30 of the object 28 are pressed against the head 12 of the fastener 10, as shown by arrow A in the figure, the resilient protrusion 22 will deform to some extent, so that the The head 2 is housed in the hole or groove 30. When the head 12 is housed in the hole or groove, the resilient protrusion 22 supplies the head 12 and the hole or groove There is a friction fit between the walls 3 4, 36 of the groove 30, so it is advantageous to mount the object 28 to the support 26. Returning to FIG. 1, the front of the annular protrusion 22 on the circumference The edge 37 is preferably sloped to facilitate the easy insertion of the head 2 into the hole or groove 30. Due to the unique design of the head 12, the object 28 can be easily mounted on the support 26 without the need for hand tools such as a village head, screwdriver and drill. These hand tools can of course be used without departing from the scope of the invention as defined herein. The friction fit between the head 12 and the object 28 will also facilitate the removal of the object 28 from the support 26 without the use of any hand tools, because the friction fit provided by the head is not necessary, , Lock up, the object 28 and the fastener; U). Referring to FIG. 2 again, the longitudinal end surface 20 of the fastener is adjacent to the support 26, and it can be determined that there is a uniform distance from the surface of the support 26 to the opposite longitudinal end 24 of the fastener; and When the straight longitudinal surface 20 touches the straight surface of the support 26 when the user pushes the fastener into the support by hand, the user will be confident that the tightness '10-

In an exemplary embodiment of the fastener 10, the head 12 is molded from: rebound: a raw plastic material, such as Nylon 66; the diameter of the annular protrusion is close to 12 mm (mm) The shaft 14 is a heat-treated # 1022 carbon steel, and extends from the longitudinal end 20 of the head to about ^ claws. Of course, those skilled in the art will recognize that other suitable materials and sizes can be used for fasteners, while still remaining within the scope of the present invention as defined herein. In this exemplary embodiment, the hole or slot 30 will be about 15 mm deep, and between the upper and lower walls 34, 36 there will be a gap of about 10 to 11 mm. The size of ^ will be recognized by those skilled in the bank, but it is still within the scope defined by the present invention. As shown in Figs. 3-5, according to a preferred embodiment of the present invention, an exemplary object mounted on a vertical support is a corner shelf. The corner frame 38 is a two-sided flat wooden board, and has a pair of straight side edge corrections, 42 'to 90. Corner meet. Milled in each of the edges 40, 42 is a substantially rectangular (section) groove 44 in which an upper wall 46 and a lower wall 48 are provided. The remaining third edge 50 of the triangular board may include a chamfered surface for decoration. As shown in Fig. 6, the angle bracket 38 can be mounted on an angle formed by two connected walls 52, 54 according to the following steps. First, take the first wall 52 that is close to the two walls with a ruler at a required degree, and draw a light pencil line 56 along the top edge of the ruler. This step is repeated again for the other wall 54 to prepare the line 58. Secondly, at least two fasteners 10 are driven along the pencil straight lines 56, 58 into the walls 52, 54. Preferably one of the fasteners should leave the corner IX 297 mm) -11-1222497 A7 _____________B7 V. Description of the invention ^ 9 ~) '---- ~-隅 2 inches, and the other should be away from the corner frame The end of the grooved material is installed. The remaining steps are to push the angle bracket 38 toward the exposed end of the fastener 10, as shown by arrow B in FIG. 6, so that the installation groove 44 is pressed toward the exposed end of each fastener 10. And deform the protrusions 2 on each exposed end of the fastener 10 so that the crotch can be received in the groove 44, so as to give the exposed head of the fastener 10 and the groove A friction fit between 44. This friction fit securely attaches the delta bracket 38 to the corner formed by the two walls 52, 54. The fastener 10 gives a friction fit to the bracket 38 to prevent the bracket from being easily removed from the bracket. The walls 52, 54 are pulled apart. At the same time, a load energy is given so that the angle bracket 38 can bear a considerable surface load (the angle bracket 38 of the exemplary embodiment is 25 pounds). Those skilled in the bank can understand that using more fasteners 10 will allow the angle bracket 38 to bear a larger load. The annular protrusion 22 of the fastener 10 provides a sufficient amount of axial surface area for the friction fit between the fastener 10 and the groove 44. In such a case, it is not necessary The angle between the two walls 52 and 54 is required to be absolutely square (I know that the corners in many homes or offices are not absolutely square when using the exemplary embodiment). As shown in FIG. 7, an alternative 'for mounting to a vertical support' is a straight shelf 60 with a horizontal slot 62, milled on the shelf substantially straight On the longitudinal end face 64. The slot 62 is adapted to receive a plurality of fasteners 10 already fixed on a vertical support. The fastener 10 provides a friction fit in the groove 62, thereby firmly mounting the shelf 60 to the vertical support.
