The specific embodiment
With reference to accompanying drawing 1-6, striking plate or strips for joint parts 10 have wherein been shown.Strips for joint parts 10 can be used for the car door as " opening-closure body ".Shown strips for joint parts 10 comprises by the integrally formed hook 11 of single piece of metal rod element.Strips for joint parts 10 preferred general curved are the shape (that is, being bent into roughly U-shaped structure) of door.Strips for joint parts 10 also comprises base portion 12, and this base portion 12 is crooked in the bottom end of the hook 11 pair of leg 11a of U-shaped roughly with the angle that is similar to the right angle.Base portion 12 preferably extends mutually on the plane that the hook 11 of U-shaped limits substantially in the opposite direction.
Hook 11 comprises pair of leg 11a and strides across these legs 11a and the joint pestle 11b that extends.Engage the preferably car body surface (not shown) almost parallel mounted thereto with strips for joint parts 10 of pestle 11b.
In addition, base portion 12 is flat (perhaps at least part of is flat) endways, and base portion 12 has a pair of connector 12a that can be installed in (for example, on the installation surface of car body) on the miscellaneous part, and described miscellaneous part is not shown.Connector 12a preferably flattens by the spherical protuberances with the rod unit end and forms circle.Screw hole 12b can get out at the center of the circle that forms by flattening spherical protuberances.
Because strips for joint parts 10 is the shapes that become to expect by with independent material bending, making strips for joint parts does not just need machine or welding.Therefore, the structure that shows has here just been simplified the manufacturing of strips for joint parts.In addition, can not produce obsolete material because make shown strips for joint parts 10, such as the fragment that might form in forming process, the output of material is improved and cost of production reduces and just to become possibility.
With reference to the accompanying drawings 6, jagged, that chimb is arranged or coarse surface can be set at the back side of connector 12a, for example form chevrons by countless square ribs projection 12c.In other words, such surface can be used for following surface, and this surface contacts with the surface that strips for joint parts 10 will be installed in car body side.
Therefore, when the screw (not shown) is passed screw hole 12b and fastening in the welded nut (not shown) time, the end of square rib shape projection 12c can be out of shape in screw fastening, even fastener 12a not by with the surface is installed evenly (for example, between connector 12a and the installation surface slight angle is arranged) also be that so above-mentioned welded nut can for example be arranged at the surface that strips for joint parts 10 is installed when installing.Thus, whole Surface Contact tilts obviously to revise to connector 12a together and not.In addition, the more stable screw of surface pressing is not easy to become flexible in fastening.
7-12 has with reference to the accompanying drawings shown another embodiment of strips for joint parts 10.Strips for joint parts 10 comprises hook 11, and the integrally formed and integrally bending of the continuous metal bar element of hook 11 and is a door shape (for example U-shaped structure).Shown strips for joint parts 10 also comprises base portion 12, and base portion 12 outwards stretches out with approximate right angle in 11 two ends of door shape hook, has therefore formed the base portion end of door shape.The choosing of door shape base end quality award from the ministry is passed the mutual side towards the opposite in the plane that is limited by door shape member and is extended.
Shown hook 11 has pair of leg 11a and passes the joint pestle 11b that leg 11a extends.Preferably, engaging pestle 11b roughly extends in parallel with the installation surface (not shown) that strips for joint parts can be installed.
With reference now to accompanying drawing 12,, shown hook 11 can be bent into by the metal bar element 13 with preset length roughly that U-shaped structure (for example, the structure of integral door shape) forms.Stretch out to such an extent that can form in the precalculated position along clavate part 13a than the more a pair of protruding 12g of the other parts of excellent element 13, thus, when excellent element 13 forms roughly U-shaped structure, can be positioned with a protruding 12g on each leg of U-shaped structure.
Then, clavate part 13a is the shape of approximate right angle in middle bent on mutually opposite direction preferably, shown in serial two point dotted line P.In other words, a leg that is limited by one of clavate part 13a is bent upwards from the curve that limits between plane that two part 13a limit and two the part 13a when another leg is reclinate.Subsequently, folded end 13c further goes back on the plane of the direction of arrow Q, and the inclined surface 13d of end 13c leans against the base portion end (being sweep) of leg 11a upward to form ring like this.In some structures, again bending twice of remaining part from the bending that two point dotted line P shows, thus can form C shape or U-shaped (for example, with the corresponding structure in both sides shown in Figure 11), protruding 12g is positioned at the center of these shapes parts.
Then, the connector 12a of flat shape can form by pressing in vertical direction (extruding) end 13c, and this can produce top and lower surface, comprise that protruding 16g forms basic flat shape.Then, shown strips for joint parts 10 can be finished by drilling screw hole 12b on each connector 12a.
In some structures, the inclined surface 12f of base portion 12 can combine to reduce the possibility of separating with leg 11a.In some these structures, in conjunction with can realizing by welding, for example electric welding by expectation.In addition, when increasing additional mechanically actuated and operation, flat connector 12a can finish by cutting and the grinding of expectation.
It is upper with the formation continuous loop that shown strips for joint parts 10 can be resisted against by the inclined surface 12f that makes base portion 12 leg 11a, thereby have improved intensity at base portion 12.In addition, because opened relatively large opening 12g (for example, the weight reducing hole) at the center of base portion 12, can not consider shape and reduce weight, its appearance profile is relatively large.And, relatively large base portion provide to shown in the firm installation of strips for joint parts 10.At manufacture view, because base portion 12 made by the plastics that form single excellent element, can in operation, cause minimum waste of material and improve the productivity ratio of material.
13-23 has shown that another one comprises the strips for joint parts 10 of hook 11 with reference to the accompanying drawings, and the continuous metal bar element of this hook and is integrally formed, and is bent into portal structures roughly.Shown in strips for joint parts 10 also comprise base portion 12, base portion locates to be bent into approximate right angle in the end of door shape hook 11 (for example, the base portion end of portal structures), and extends in mutual opposite direction with respect to the plane of being set by portal structures.
Shown in hook 11 preferably include pair of leg 11a and cross these legs 11a and the joint pestle 11b that extends.Engage pestle 11b preferred parallel and extend in the surperficial (not shown) of car body, for example, the surface of strips for joint parts 10 will be installed on it.
In addition, base portion 12 preferably is substantially shaped as complete plane and has a pair of connector 12a that is installed in (for example, the installation of car body surface) on other elements, and described other elements do not illustrate.Connector 12a can have circular configuration roughly and can as described above ball bumps 13b be flattened to form.Can get out at the center of connector 12a screw hole 12b.
As shown in Figure 14, metal bar element 13 can be cut into predetermined length.Then, as shown in Figure 15, can form hook 11 by excellent element 13 being bent into roughly U-shaped structure (that is, roughly portal structures).Then, can cast or similar means (with reference to accompanying drawing 16) form a pair of protruding 13b by the predetermined portions on the clavate part 13a of U-shaped element roughly.
The terminal 13e of clavate part 13a can be cast into projection or extension, as shown in figure 17.Terminal 13e can form fork-shaped, as shown in Figure 18.Then, shown in accompanying drawing 19 (a) and accompanying drawing 19 (b), a pair of clavate part 13a can be bent into approximate right angle in the opposite direction.A pair of clavate part 13a can also be crooked in different directions from the bending first time, as shown in Figure 20, further, as shown in Figure 21, a pair of clavate part 13a can be crooked once so that the base portion end that the fork-shaped recess 13f of terminal 13e holds the 11a that makes a tripping kick again.As shown in Figure 22, base portion 12 can form by casting subsequently, then, as shown in Figure 23, can get out like that as shown in Figure 13 screw hole 12b.
As mentioned above, by only using single excellent element 13, might reduce the number of elements for the manufacture of strips for joint parts 10.And, can strengthen base portion 12 by leg 11a is fitted into recess 12h.In addition, whole base portion 12 is formed flat shape so that more easy with contacting of vehicle installation surface.
