DETAILED DESCRIPTION OF THE EMBODIMENTS
Before the present invention is described in greater detail, it should be noted that like elements are denoted by the same reference numerals throughout the disclosure.
As shown in FIGS. 2 to 6, a first embodiment of a nailer according to the present invention is for firing a nail 21 into an object 6, and includes a magazine 2, a base seat 3, two abutment members 4 and two positioning units 5.
The magazine 2 is for receiving a plurality of nails 21 (only one is shown in FIG. 6).
The base seat 3 has a main body 31 and two support portions 32. The main body 31 is connected to the magazine 2, and is formed with a nail passage 311 (see FIG. 6). The support portions 32 are spaced apart from each other and connected to the main body 31. Each of the support portions 32 has an engaging structure 33 that has an elongate top wall segment 331, a pair of spaced-apart extending wall segments 332 parallel to each other and extending from the top wall segment 331 toward the object 6 in a first direction (A), and a pair of distal wall segments 333 extending respectively from distal ends of the extending wall segments 332 proximate to the object 6 toward each other in opposite second and third directions (B, C). The top wall segment 331, the extending wall segments 332 and the distal wall segments 333 of each of the support portions 32 cooperatively define an engaging space 334 thereamong that extends in an engaging direction (X1) transverse to the first, second and third direct ions (A, B, C). Each of the support portions 32 further has a retaining hole 34 that is formed in one of the extending wall segments 332 thereof, and that communicates spatially with the engaging space 334 thereof.
The abutment members 4 correspond respectively to the support portions 32 of the base seat 3. For simplification, one of the abutment members 4 is described in the following.
The abutment member 4 has first and second engaging portions 41, 42 that are spaced apart from each other, and a connecting portion 43 that is connected between the first and second engaging portions 41, 42. The engaging structure 33 of the corresponding support portion 32 engages detachably and slidably either one of the first and second engaging portions 41, 42. Each of the first and second engaging portions 41, 42 has an engaging surface 412, 422 that is connected to the connecting port ion 43 and that faces the engaging surface 412, 422 of the other one of the first and second engaging portions 41, 42, and an abutment surface 411, 421 that is opposite to the engaging surface 412, 422. A distance (L1, L2) between the abutment surface 411, 421 and the engaging surface 412, 422 of one of the first and second engaging portions 41, 42 is different from that of the other one of the first and second engaging portions 41, 42 (see FIGS. 5 and 8). In this embodiment, the distance (L1) between the abutment surface 411 and the engaging surface 412 is greater than that between the abutment surface 421 and the engaging surface 422. Each of the first and second engaging portions 41, 42 further has four positioning recesses 44, 45 that are formed in a periphery thereof.
The positioning units 5 correspond respectively to the support portions 32 of the base seat 3. Each of the positioning units 5 includes a ball body 51 that is movable along the retaining hole 34 of the corresponding support portion 32, a resilient member 52 that is disposed in the retaining hole 34 of the corresponding support portion 32 and that biases resiliently the ball body 51 toward the engaging space 334 of the corresponding support portion 32, and a stop member 53 that engages threadedly the retaining hole 34 of the corresponding support portion 32 and that is disposed at one side of the resilient member 52 distal from the ball body 51. Each of the positioning units 5 is operable to switch between a locking state where the ball body 51 is partially retained in the engaging space 334 of the corresponding support portion 32, and an unlocking state where the ball body 51 is totally retracted into the retaining hole 34 of the corresponding support portion 32.
Referring to FIGS. 3 to 5, the engaging structure 33 of each of the support portions 32 is engageable with the second engaging portion 42 of the corresponding abutment member 4 such that: the second engaging portion 42 of each of the abutment members 4 is retained in the engaging space 334 of the corresponding support portion 32; the connecting portion 43 of each of the abutment members 4 is disposed between the distal wall segments 333 of the corresponding support portion 32; and the engaging surfaces 412, 422 of the first and second engaging portions 41, 42 of each of the abutment members 4 respectively abut against opposite sides of each of the distal wall segments 333 of the corresponding support portion 32. At this time, each of the positioning units 5 is in the locking state where the ball body 51 of each of the positioning units 5 engages one of the positioning recesses 45 of the corresponding abutment member 4 for prevent relative sliding movement between the corresponding support portion 32 and the corresponding abutment member 4.
Referring to FIG. 6, in operation of the nailer, the abutment surfaces 411 of the abutment members 4 (only one is shown) can be disposed to abut against the object 6, such that a distance between the object 6 and the base seat 3 is equal to the thickness of the first engaging portion 41 of each of the abutment members 4 (i.e., L1).
Referring to FIGS. 7 and 8, to adjust the distance between the object 6 and the base seat 3 in operation of the nailer, the first engaging portion 41 of each of the abutment members 4 is held manually and moved in a disengaging direction (X2) opposite to the engaging direction (X1) to force the corresponding positioning unit 5 to switch into the unlocking state where the ball body 51 of the corresponding positioning unit 5 is disengaged from the one of the positioning recesses 45 of the abutment member 4, so as to permit relative sliding movement between the corresponding support portion 32 and the abutment member 4, and to therefore disengage the second engaging portion 42 of the abutment member 4 and the corresponding support portion 32. Then, each of the abutment members 4 is inverted and moved relative to the base seat 3 in the engaging direction (X1), so as to drive the engaging portion 41 thereof to slide into the engaging space 334 the corresponding support portion 32 until the ball body 51 of the corresponding positioning unit 5 engages one of the positioning recesses 44 of the first engaging portion 41 for prevent relative sliding movement thereof relative to the corresponding support portion 32. Comparing FIGS. 5 and 8 and referring to FIG. 6, since the first and second engaging portions 41, 42 of each of the abutment members 4 are different in thickness (i.e., L1 and L2), the nailer can be operated to fire a nail 21 into different locations of the object 6.
To sum up, by virtue of the configuration of the engaging structures 33, the abutment members 4 and the positioning units 5, each of the abutment members 4 can be engaged with or disengaged from the corresponding engaging structure 33 manually and easily.
Referring to FIG. 9, a second embodiment of the nailer according to the present invention is similar to the first embodiment. The differences between the first and second embodiments reside in that the support portions of the base seat 3 of the second embodiment cooperatively form the engaging structure 33′, and that the second embodiment only includes one abutment member 7.
The engaging structure 33′ is configured to be similar to that of the first embodiment. The abutment member 7 is also configured to be similar to that of the first embodiment, and includes two engaging portions 71, 72 that have different thicknesses (L1, L2). The nailer can also be operated to fire a nail 21 into different locations of an object by engaging different engaging portions 71, 72 with the engaging structure 33′.
While the present invention has been described in connection with what are considered the most practical embodiment, it is understood that this invention is not limited to the disclosed embodiments but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
