Description:

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] This invention relates to a slide hammer puller for car-body sheet metals of a vehicle, particularly to one consisting of a driven rod, a slide hammer and at least one pulling member, wherein a shank body of the driven rod extended through the slide hammer has a stop portion disposed at a proper position of the shank body for corresponding to a hammer face of one end of the slide hammer and is combined with each of the pulling members at one end of the shank body. When the pulling member is placed on a dent of a car-body sheet metal, hot-melt adhesives are filled between the pulling member and the dent of the car-body sheet metal. After the hot-melt adhesives get dry, a user can strike the slide hammer toward the stop portion of the driven rod and make the driven rod have backward pulling movements to force the pulling member to pull the dent of the car-body sheet metal outwardly to its normal smooth position, by which the dent of the car-body sheet metal can be repaired without need of disassembling interior parts and accessories of a vehicle.

[0003] 2. Description of the Prior Art

[0004] Generally speaking, when a vehicle gets dents on the outer surfaces of car-body sheet metals under exterior forces, a known conventional way in repairing such dents is firstly to disassemble the car-body sheet metals from the whole car-body construction, and then to hammer the dents from the inner surfaces of the car-body sheet metals outwardly to their normal smooth positions with a hammer. However, it is a waste of time and labor to disassemble the car-body sheet metals. Moreover, the car-body sheet metals having ever been disassembled are liable to become loose, or even worse to be taken off the whole car-body construction at an unexpected time to cause dangerous accidents.

SUMMARY OF THE INVENTION

[0005] The main purpose of the invention is to offer a slide hammer puller for car-body sheet metals of a vehicle capable of repairing dents of car-body sheet metals without need of disassembling interior parts and accessories of a vehicle.

[0006] The main feature of the invention is to provide a slide hammer puller for car-body sheet metals of a vehicle mainly including a driven rod with a shank body in long-rod shape having a stop portion disposed at a proper position of the shank body and a combining end disposed at one end of the shank body; a slide hammer capable of being extended through by the driven rod and having a passage disposed through a center of the slide hammer as well as a hammer face disposed at one end of the slide hammer and corresponding to the stop portion of the driven rod; at least one pulling member capable of being combined to one end of the driven rod, each of the pulling members provided with a combined portion for corresponding to the combining end of the driven rod.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0013] A preferred embodiment of a slide hammer puller for car-body sheet metals of a vehicle in the present invention, as shown in FIG. 1, mainly includes a driven rod 1, a slide hammer 2 and at least one pulling member 3.

[0014] The driven rod 1 has a shank body 10 in long-rod shape. The shank body 10 is provided with a handle 11 disposed at one end of the shank body 10 and a combining end 13 in threaded-rod shape disposed at the other end of the shank body 10. A stop portion 12 with a larger diameter is disposed at an end face of an inner side of the handle 11.

[0015] The slide hammer 2 capable of being extended through by the shank body 10 of the driven rod 1 has a passage 20 disposed through a center of the slide hammer 2 and a hammer face 21 with a larger diameter disposed at one end of the slide hammer 2 and corresponding to the face of the stop portion 12 of the driven rod 1.

[0016] Each of the pulling members 3 capable of being combined to one end of the driven rod 1 has a combined portion 30 with internal threads disposed at one end surface of the pulling member 3 for corresponding to the combining end 13 of the driven rod 1 and a concave surface 31 inwardly formed at the other end surface of the pulling member 3. The pulling members 3 are capable of being provided with various sizes for the convenience of being fitted with different areas of dents of car-body sheet metals 4 required for pulling.

[0017] In assembling and using, referring to FIGS. 1 to 5, firstly extend the driven rod 1 through the slide hammer 2 with the hammer face 21 of the slide hammer 2 corresponding to the stop portion 12 of the driven rod 1. Secondly, choose one of the pulling members 3 with suitable size to be combined with the combining end 13 of the driven rod 1, by which the slide hammer puller for car-body sheet metals of a vehicle in the present invention is assembled. When a dent of a car-body sheet metal 4 is to be pulled outward, place the concave surface 31 of the pulling member 3 on the dent of the car-body sheet metal 4, as shown in FIG. 2, and fill hot-melt adhesives 5 into the gap formed between the circumference of the concave surface 31 of the pulling member 3 and the dent of the car-body sheet metal 4 until the hot-melt adhesives 5 are spread with the whole gap and out of the circumference of the pulling member 3, as shown in FIG. 3. After the hot-melt adhesives 5 get dry, the pulling member 3 and the car-body sheet metal 4 are bonded together. At the moment, a user can hold the driven rod 1 with one hand and strike the slide hammer 2 toward the stop portion 12 of the driven rod 1 with the other hand, by which the driven rod 1 can have backward pulling movements under the striking forces of the hammer face 21 of the slide hammer 2 to the stop portion 12 of the driven rod 1 to make the pulling member 3 gradually pull the dent of the car-body sheet metal 4 outwardly, as shown in FIG. 4. When the dent of the car-body sheet metal 4 has been pulled outwardly to its normal smooth position, the user can cut the hot-melt adhesives 5 to separate the car-body sheet metal 4 and the pulling member 3 with a cutting tool 6, as shown in FIG. 5. And then, the car-body sheet metal 4 is capable of being handled with grinding, polishing and painting works.

[0018] The invention has the following advantages and effects, as can be understood from the aforesaid description.

[0019] 1. The slide hammer puller of the present invention is capable of repairing dents of the car-body sheet metals without need of disassembling interior parts and accessories of a vehicle, which greatly saves time and labor in disassembling and assembling car-body parts and accessories.

[0020] 2. The slide hammer puller of the present invention with simple selective combination is capable of being quickly assembled and easily handled to increase working efficiency.

[0021] 3. The pulling members of the slide hammer puller of the present invention are provided with various sizes for being fitted with different areas of dents of car-body sheet metals required for pulling.

[0022] While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
