TECHNICAL FIELD

[0001] The present disclosure relates to a hook structure for a nailer and more particularly to a hook structure for a nailer capable of being hung on both sides alternatively.

PRIOR ART

[0002] Small power tools have become indispensable operating tools for various engineering purposes such as building, civil construction and decoration since they are portable to carry, stably powered, and easy to operate. With the maturity of production technologies, a variety of user-friendly power tools have become available in the market so as to provide consumers with more choices. Amongst those tools, a nailer is known as one of commonly used small power tools.

[0003] A hook is often disposed on a seat body of a handle of a nailer for the placement and storage of the nailer. In the prior art, a hook of the nailer is fixedly assembled on one side of the seat body, that is, the hook is fixed to either the left side or the right side of the handle, and thus cannot be operated interchangeably on the two sides. When the hook is disposed on the left side, it is inconvenient for an operator holding the nailer with his/her left hand to hang the nailer on his/her waist belt. On the other hand, when the hook is disposed on the right side, it is also inconvenient for an operator holding the nailer with his/her right hand to hang the nailer on the waist belt. Therefore, the difference between the left-handedness and right-handedness of users leads to different habits in picking up and/or placing the nailer or subjective restrictions in the placement environment thereof, thus causing inappropriateness and inconvenience in the operation as limited by the original design of the nailer. Moreover, an existing nailer cannot adjust and receive the hook in accordance with different use scenarios such that the hook is always protruding from the surface of the tool, creating a risk of tripping over of the user when the hook is not in use.

[0004] In view of the above, directed to the problems in the use of a hook with a known nailer seat body, it is an objective and direction for those skilled in the industry to contemplate and develop a more easily operated and more practical hook structure with better adaptation to the sinistral or dextral user.

SUMMARY OF THE UTILITY MODEL

[0005] One of the objectives of the present disclosure is to provide a hook structure for a nailer that enables an operator to selectively hang the hook on the left or right side based on his/her own operating habit or need, or enables the operator to position the hook depending on different scenarios.

[0006] In order to achieve the above objective, the present disclosure provides a hook structure for a nailer coupled to a nailer body, comprising a seat body and a hook. The seat body comprises a first assembling port, a second assembling port in communication with the first assembling port, and a seat face, wherein the seat face comprises a plurality of locating holes. The hook is detachably positioned on the seat body. The hook comprises an extending handle, a coupler connected to the extending handle, and a buckle part elastically connected to the coupler, wherein the coupler is selectably inserted into the first assembling port or the second assembling port, and the buckle part is movably engaged with a corresponding locating hole.

DETAILED DESCRIPTION OF PREFERRED E BODI ENTS

[0020] The preferred embodiments and technical contents of the present disclosure will be illustrated below in conjunction with the drawings. However, the drawings are only intended for reference and explanation, and should not be considered as limiting the scope of the present disclosure.

[0021] As shown in Figs. 1-5, a first embodiment of the present disclosure provides a hook structure 100 for a nailer coupled to a nailer body 300. The nailer body 300 herein preferably refers to a pneumatic nailer or other pneumatic small power tools. However, in other embodiments, the nailer body 300 may also be, but not limited to, other electrical small power tools, for example internal combustion actuated nailers or powder actuated nailers.

[0022] The hook structure 100 for a nailer of the present embodiment comprises a seat body 110 and a hook 200. The seat body 110 is provided with a first assembling port 120, a second assembling port 130 in communication with the first assembling port 120, and a seat face 140, wherein the seat face 140 is provided with a plurality of locating holes 150. As shown in Figs. 2 and 3, the seat body 110 further comprises a plurality of bulges 160 protruding from the seat face 140 and a channel 170 in communication with the first assembling port 120 and the second assembling port 130. The respective bulges 160 herein may preferably enhance the structural strength of the respective locating holes 150, such that a buckle part 230 of the hook 200 is more stably coupled on the seat body 110.

[0023] As shown, the hook 200 comprises an extended handle 210, a coupler 220 connected to the extended handle 210, and a buckle part 230 elastically connectable to the coupler 220, wherein the coupler 220 may be selectably inserted into the first assembling port 120 or the second assembling port 130; and the buckle part 230 may be movably engaged with a corresponding locating hole 150. The buckle part 230 in the present embodiment has a rod part 232 and a convex part 234 connected to the rod part 232. The convex part 234 protrudes from the surface of the coupler 220 and is disposed opposite to the locating hole 150. The coupler 220 further comprises a notch 240 for receiving the buckle part 230. The notch 240 is disposed offset on one side of the coupler 220. Suppose that the coupler 220 is folded in half, the buckle part 230 is then located at a position of a half of the coupler 220. The rod part 232 and the convex part 234 are elastically movable in the notch 240.

[0024] In addition, in the first embodiment as shown in Figs. 3-5, the hook 200 is detachably located at the seat body 110, and the coupler 220 of the hook 200 is slidable within the channel 170 and positioned on the seat face 140. Since the buckle part 230 has a certain elasticity, the buckle part 230 can be detached from the locating hole 150 when the operator pulls out the hook 200 forcibly. However, as shown in Fig. 3, a hand tool 310 such as a flathead screwdriver may also be used to detach the buckle part 230 from the locating hole 150. In addition, each of the bulges 160 further has at least one chamfer 162 on one side and a wall face 180 on the other side thereof opposite to the chamfer 162. As shown, the respective wall faces 180 comprise a first abutting face 182, a second abutting face 184 and a third abutting face 186; and the respective locating holes 150 comprise a first hole 152, a second hole 154, and a third hole 156. The first abutting face 182 is disposed opposite to the first hole 152, the second abutting face 184 is disposed opposite to the second hole 154, and the third abutting face 186 is disposed opposite to the third hole 156.

[0025] In the present embodiment, along an assembling path of the first assembling port 120, the locating holes 150 from far to near are the first hole 152, the second hole 154, and the third hole 156. A face of the respective holes 152, 154 and 156 opposite to the respective abutting faces 182, 184 and 186 is a chamfer 162, so as to smoothly guide the convex part 234 into the respective locating holes 150, or to smoothly detach the convex part 234 from the third hole 156 and slide it towards the second hole 154 or the first hole 152 in sequence.

[0026] For example, an inclination angle of the first abutting face 182 and the second abutting face 184 is preferably smaller than the inclination angle of the chamfer 162, such that when sliding from the second hole 154 to the third hole 156, the user only needs to exert a small force to detach the convex part 234 from the second hole 154 and move it towards the third hole 156. The inclination angle of the third abutting face 186 is smaller than that of the second abutting face 184 or the first abutting face 182, so as to achieve an effect of stopping the convex parts 234. Hence, when the user hangs the nailer body 300, the hook 200 can be prevented from being released from the first assembling port 120.

[0027] Furthermore, when the convex part 234 is to be released from the third hole 156, a hand tool 310 such as a flathead screwdriver may be used to push the convex parts 234 to detach it from the third abutting face 186 of the third hole 156, and then the hook 200 may be released from the first assembling port 120 and shifted to the second assembling port 130 as needed. For the assembling path, structure and steps of the hook 200 to the second assembling port 130, reference can be made to what is described above with respect to assembling the hook 200 to the first assembling port 120, and will not be repeated here.

[0028] The inclination angle herein preferably refers to a vertical line (not shown) assumed to pass through the respective holes 152, 154 and 156 of the locating holes 150. The inclination angles of the respective abutting faces 182, 184 and 186 are angles between the respective abutting faces 182, 184 and 186 and the vertical line. Likewise, the inclination angle of the chamfer 162 is also an angle between the vertical line and the chamfer 162.

[0029] Referring also to Fig. 6, when the operator hangs the hook 200 on a nailer holder 320 or other appropriate holders as needed, the buckle part 230 of the hook 200 may be freely pushed into the channel 170 and elastically engaged in an appropriate locating hole 150. When it is intended to pull out the buckle part 230 of the hook 200 and detach it from the corresponding locating hole 150, the buckle part 230 may be pulled out using a hand tool 310 or directly with the elasticity of the buckle part 230 per se; then the convex parts 234 can be detached from the locating hole 150, retreated to the next corresponding locating hole 150, and located there, as shown in Figs. 3-5.

[0030] Here, it should be noted that the respective bulges 160 are provided on the seating face 140 row by row in a staggered manner. In other words, the locating holes 150 are also provided on the seating face 140 row by row in a staggered manner, wherein the buckle part 230 is disposed offset on the other side of the coupler 220. Therefore, along the assembling path of the second assembling port 130, the respective bulges 160 sequentially dispose the plurality of locating holes 150 on the seat face 140. "Row by row" herein preferably refers to 2 rows; and each row of bulges/locating holes 150 comprises 3 bulges/locating holes. In the present embodiment, the number of bulges 160/locating holes 150 is preferably 6 in total, but may be varied depending on the actual dimensions of the nailer body 300, and is not limited here.

Furthermore, the extending handle 210 is provided with at least one opening 250 for hanging onto a certain object (not shown).

[0031] Further, the hook structure for a nailer of the present disclosure enables the operator to selectively hang the nailer on the left or right side based on his/her own operation habit or need, or to position the hook based on different scenarios, as shown in Fig. 7. For the structure and operation related to Fig. 7, reference can be made to what is described above, and will not be repeated here.

[0032] As shown in Figs. 8-9, a second embodiment of the present disclosure provides a hook structure 400 for a nailer of the present embodiment which comprises a seat body 410 and a hook 500. The seat body 410 is provided with a first assembling port 420, a second assembling port 430 in communication with the first assembling port 420, and a seat face 440, wherein the seat face 440 is provided with a plurality of locating holes 450. Each of the locating holes 450 has a furrow 458. As shown in Figs. 8 and 9, the seat body 410 further comprises a plurality of bulges 460 protruding from the seat face 440 and a channel 470 in communication with the first assembling port 420 and the second assembling port 430. The respective bulges 460 herein may preferably enhance the structural strength of the respective locating holes 450, such that a buckle part 530 of the hook 500 is more stably coupled on the seat body 410.

[0033] As shown, the hook 500 comprises an extended handle 510, a coupler 520 connected to the extended handle 510, and a buckle part 530 elastically connectable to the coupler 520, wherein the coupler 520 may be selectably inserted into the first assembling port 420 or the second assembling port 430; and the buckle part 530 may be movably engaged with a corresponding locating hole 450. The buckle part 530 in the present embodiment has a rod part 532, a convex part 534 connected to the rod part 532, and a protruding part 536 connected to the convex part 534. The convex part 534 protrudes from the surface of the coupler 520 and is disposed opposite to the corresponding locating hole 450. The coupler 520 further comprises a notch 540 for receiving the buckle part 530. The notch 540 is disposed offset on one side of the coupler 520. The rod part 532, the convex part 534, and the protruding part 536 are elastically movable in the notch 540. The protruding part 536 protrudes from the surface of the convex part 534 in parallel to the notch 540 and is disposed opposite to the furrow 458 of the corresponding locating hole 450.

[0034] In addition, in the second embodiment as shown in Figs. 8-9, the hook 500 is detachably located at the seat body 410, and the coupler 520 of the hook 500 is slidable within the channel 470 and positioned on the seat face 440. Since the buckle part 530 has a certain elasticity, the buckle part 530 can be detached from the locating hole 450 when the operator pulls out the hook 500 forcibly. In addition, each of the bulges 460 further has at least one chamfer 462 on one side and a wall face 480 on the other side thereof opposite to the chamfer 462.

[0035] As shown in Fig. 9, the protruding part 536 engages behind the seat face 440 such that detaching the buckle part 530 from the corresponding locating hole requires usage of a tool, such as a flathead screwdriver as shown in Fig. 3. Inadvertent releasing the hook 500 from the first assembling port 420 is prevented.

[0036] Further, the hook structure for a nailer of the second embodiment also enables the operator to selectively hang the nailer on the left or right side based on his/her own operation habit or need, or to position the hook based on different scenarios, as shown in Fig. 7.

[0037] In view of the above, the embodiments as disclosed in the present disclosure should be considered as for illustrating and not limiting the present disclosure.
