Description

[Technical field]

[0001] The present invention relates to an engagement device for a lighting device, and particularly to an engagement device for a lighting device applied in the lighting field. [Background technology]

[0002] In order to work smoothly in a dark work environment or in a dark place, or to exercise safely at night, workers or athletes generally use lighting devices. There are many types of lighting devices that have been commercially available, but most of them are headlight types that are worn on the head so that both hands can be used freely. For example, the "Improvement of Headlight Structure" in Patent Document 1 allows users to wear it on their heads, but the wearing device and lighting device are fixed only by a simple magnetic method, so the lighting device can come off the attachment / detachment device even when a light external force is applied. In particular, there is a high risk of the lighting device being damaged when shaking the head.

[0003] For example, the "separation prevention magnet buckle" of Patent Document 2 is used to assemble a lighting device, and by performing complex operations in the first, second, and third directions, the engagement block can be fitted laterally into the engagement space of the engagement part, and the auxiliary engagement block can be fitted laterally into the auxiliary engagement space of the auxiliary engaged part, but the structure is complex and the usability is poor. Furthermore, the various headlights mentioned above have a common problem. This problem is that when attaching a headlight to an article (such as a helmet) to which the headlight is to be attached, the user must always take off the article to which the headlight is to be attached. If the user does not take off the article to which the headlight is to be attached, it is difficult for the user to accurately attach the headlight to the article to which the headlight is to be attached. However, taking off the article to which the headlight is to be attached is troublesome for the user, and sometimes causes a safety problem.

[0004] In view of this situation, the inventors of the present invention have conducted extensive research and have completed the engagement device for a lighting device of the present invention. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described with reference to the accompanying drawings, in which the same reference numerals denote the same or similar configurations.

[0022] Please refer to Figures 1 to 14. As shown in Figures 1 to 14, the engagement device of the lighting device according to the present invention has two main embodiments.

[0023] (First embodiment) First, refer to FIG. 1 to FIG. 6 (first embodiment). The engagement device for the lighting device according to the first embodiment of the present invention includes a lamp holder 10, a lighting device 20, and a positioning seat 30. The lighting device 20 is pivotally attached to one side of the lamp holder 10 for lighting. The first magnetic attraction member 1 is embedded in the other side of the lamp holder 10, and two slots 2 are recessed. The two slots 2 are located on both sides of the first magnetic attraction member 1. The two slots 2 are partially connected to each other and formed into a concave shape. After the two slots 2 are connected, an open opening (described in the placement direction of FIG. 3) is formed below. The positioning seat 30 is coupled to one side of the first magnetic attraction member 1 of the lamp holder 10. Two engagement protrusions 3 are protruding from one side of the positioning seat 30. The two engagement protrusions 3 are detachably engaged with the two slots 2. The two engaging protrusions 3 are combined according to the shape of the two slots 2. The two engaging protrusions 3 are installed at a distance from each other, and a second magnetic attraction member 4 is attached between the two engaging protrusions 3. The lamp holder 10 and the positioning seat 30 are magnetically coupled to each other through the first magnetic attraction member 1 and the second magnetic attraction member 4. The first magnetic attraction member 1 is brought close to one end of the second magnetic attraction member 4. The other end of the second magnetic attraction member 4 is installed on the positioning seat 30 in an inclined manner away from the first magnetic attraction member 1. When the side of the lamp holder 10 having the first magnetic attraction member 1 is brought close to the side of the second magnetic attraction member 4 of the positioning seat 30, the lamp holder 10 is pulled by the magnetic attraction force to combine with the positioning seat 30, and the two engaging protrusions 3 are detachably engaged with the corresponding slots 2, and are reliably positioned.

[0024] According to the above description, the present invention may be applied to a strap 40 (also called a headband), as shown in Fig. 6. For example, when a user is running at night, in order to enhance safety, the user puts the strap 40 and the positioning seat 30 together on the head, and then attaches the lamp holder 10 with the lighting device 20 to the positioning seat 30. When the user brings the lamp holder 10 with the lighting device 20 closer to the positioning seat 30, the magnetic attraction force between the first magnetic attraction member 1 and the second magnetic attraction member 4 gradually increases as they approach each other, and when the distance between the lamp holder 10 and the positioning seat 30 is very close, the magnetic attraction force between the first magnetic attraction member 1 and the second magnetic attraction member 4 generates a large pulling force. In short, due to the characteristics of the magnetic field, when the first magnetic attraction member 1 and the second magnetic attraction member 4 are brought close to each other, they attract each other and are automatically guided (because the second magnetic attraction member 4 is designed with an inclination, the magnetic force direction of the magnetic field is also different when the second magnetic attraction member 4 is designed with an inclination), so that after the first magnetic attraction member 1 is inclined toward the second magnetic attraction member 4, the magnetic force directions of both magnetic fields attract each other and are automatically guided, so that the lamp holder 10 of the lighting device 20 is quickly combined with the positioning seat 30, and each engaging protrusion 3 is engaged with each slot 2, so that the lamp holder 10 and the positioning seat 30 can be quickly assembled. Also, according to the experimental results, one end of the second magnetic attraction member 4 provided on the positioning seat 30 approaches the first magnetic attraction member 1. The other end of the second magnetic attraction member 4 is away from the first magnetic attraction member 1, and the second magnetic attraction member 4 is inclined and installed on the positioning seat 30. This installation method ensures that the maximum magnetic attraction force is obtained between the first magnetic attraction member 1 and the second magnetic attraction member 4, which automatically guides the lamp holder 10 and the positioning seat 30 together, and prevents the lamp holder 10 from being easily detached from the positioning seat 30, so that the lighting device 20 can be used reliably and normally.

[0025] Based on the above description, other technical features of the present invention will be described below. First, refer to FIG. 2. The lighting device 20 according to the first embodiment of the present invention is assembled with the lamp holder 10 so as to be swingable. In order to allow the user to adjust the lighting angle of the lighting device 20, the lamp holder 10 is pivotally mounted on both ends of one side of the lighting device 20, and has protruding parts 101 protruding vertically. Axle holes 102 are recessed on the corresponding surfaces of the protruding parts 101. The lighting device 20 has a number of shafts 201 which are installed corresponding to the respective shaft holes 102 and can be pivotally mounted to each other. When the shafts 201 are pivotally mounted to the respective shaft holes 102, the lighting device 20 is pivotally mounted to the lamp holder 10 (the above-mentioned shafts 201 and the shaft holes 102 are installed facing each other).

[0026] When the lamp holder 10 and the positioning seat 30 are assembled, they are firmly fixed and are prevented from being easily dislodged. As shown in Fig. 1-1 and Fig. 3, the first blocking plate 21 extends horizontally from the groove of each slot 2 of the lamp holder 10 toward the first magnetic attraction member 1 (the first blocking plate 21 forms the shape of the groove of each slot 2). Each first blocking plate 21 forms a stopper surface 211 on one side inside the slot 2. Since the second blocking plate 31 extends horizontally from the peripheral portion of each engaging protrusion 3 of the positioning seat 30 (the second blocking plate 31 is similarly formed according to the shape of each engaging protrusion 3), when a user holds the lamp holder 10 with the lighting device 20 in his hand and brings it close to the positioning seat 30, the lamp holder 10 and the positioning seat 30 are attracted to each other by the magnetic attraction force of the first magnetic attraction member 1 and the second magnetic attraction member 4, and then each second blocking plate 31 is instantly engaged in the corresponding slot 2. The outer surface of each second blocking plate 31 abuts against the stopper surface 211 of each first blocking plate 21. This provides a preferable robustness after the lamp holder 10 and the positioning seat 30 are engaged with each other, and prevents the lamp holder 10 from coming off the positioning seat 30 when an external force is applied.

[0027] In order to reliably attach the second magnetic attraction member 4 to the positioning seat and prevent it from coming off due to the influence of the magnetic force of the first magnetic attraction member 1, as shown in Figs. 3 to 5, an assembly tank 32 is recessed on the back side of the two engaging ridges 3 of the positioning seat 30. A protrusion 33 is protruded from the assembly tank 32 between the two engaging ridges 3. The second magnetic attraction member 4 is attached inside the assembly tank 32. Holders 321 are provided on both sides inside the assembly tank 32. Each holder 321 protrudes toward the groove mouth direction from the bottom surface of the assembly tank 32. Each holder 321 is formed in an L-shape (the holder 321 is L-shaped when viewed from above and below). The second magnetic attraction member 4 is engaged between the two holders 321 and the bottom surface of the assembly tank 32. A U-shaped through hole 322 is formed in the bottom surface of the assembly tank 32 through the protrusion 33. It mainly brings the second magnetic attraction member 4 close to one end of the first magnetic attraction member 1, and maintains an optimal magnetic attraction force without being isolated. An inclined guide surface 323 is formed on one side of each holder 321 facing the bottom of the assembly tank 32. The second magnetic attraction member 4 abuts against the inclined guide surface 323 of each holder 321, and approaches the first magnetic attraction member 1 when one end of the second magnetic attraction member 4 couples the lamp holder 10 with the positioning seat 30. The other end of the second magnetic attraction member 4 moves away from the first magnetic attraction member 1. As shown in the figure, the lower end of the second magnetic attraction member 4 (the position corresponding to the through hole 322) approaches the first magnetic attraction member 1, and the other end of the second magnetic attraction member 4 (not corresponding to the position of the through hole 322) moves away from the first magnetic attraction member 1. Therefore, since the second magnetic attraction member 4 is installed in an inclined manner via the second magnetic attraction member 4, a maximum and optimal magnetic attraction force is generated between the second magnetic attraction member 4 and the first magnetic attraction member 1, thereby preventing the lamp holder 10 from easily coming off the positioning seat 30.

[0028] After the second magnetic attraction member 4 is inclined and installed as described above, the second magnetic attraction member 4 forms a main axis line A near one end of the first magnetic attraction member 1. The second magnetic attraction member 4 forms an inclined guide line B away from one end of the first magnetic attraction member 1. The main axis line A and the inclined guide line B form an included angle C. The angle of the included angle C is 10 to 32 degrees, and preferably 20.5 degrees (see FIG. 4).

[0029] In addition, in this invention, a pressing plate 301 is provided at the top end of the positioning seat 30, which extends vertically toward the lamp holder 10, so that the user can quickly and easily remove the lamp holder 10 from the positioning seat 30 after operation. The angle between the pressing plate 301 and the positioning seat 30 is 90 degrees. After the lamp holder 10 is attached to the positioning seat 30, the user applies a downward force to the pressing plate 301 with one of the multiple fingertips and an upward force to the lighting device 20 with the other fingertip. Since the lighting device 20 is pivoted to the lamp holder 10, when the lighting device 20 is swung, the lamp holder 10 also moves together with it. The two engaging protrusions 3 of the positioning seat 30 are disengaged from the two slots 2 by the force applied in the up and down opposite directions, and the lighting device 20 can be removed from the positioning seat 30 together with the lamp holder 10 (see Figures 4 and 5).

[0030] Second embodiment The first embodiment of the present invention has been described above, and the second embodiment of the present invention will be described below. Please refer to Figs. 7 to 14. As shown in Figs. 7 to 14, the second embodiment of the present invention is different from the first embodiment in the following two points. First, as for the place of use, as shown in Fig. 6, connection parts 302 (having V-shaped holes) are provided on both sides of the positioning seat 30 so that it can be worn on the head of an exerciser, and straps 40 are detachably attached to each connection part 302. In short, the lamp holder 10 is attached to the strap 40, and the user wears the strap 40 on the head (or other wearable part) or directly adheres it to the helmet as shown in Fig. 13, and it can be easily used as lighting at the construction site.

[0031] Another difference between the second embodiment and the first embodiment is the top end portion of the positioning seat 30. The pressing plate 301 according to the first embodiment is integrally formed with the positioning seat 30, but in the second embodiment, it is formed in a swingable manner. For this reason, the positioning seat 30 is provided with a pivoting portion 303. One end of the control member 50 is pivoted to the pivoting portion 303. The control member 50 has an L-shape when viewed from the side. The other end of the control member 50 protrudes from the positioning seat 30. The lamp holder 10 is combined with the positioning seat 30. By swinging the one end of the control member 50 protruding from the positioning seat 30, the lamp holder 10 is pushed by the one end of the control member 50 pivoted to the pivoting portion 303, and a part of the magnetic attraction force between the first magnetic attraction member 1 and the second magnetic attraction member 4 is released, and the lamp holder 10 and the positioning seat 30 can be quickly removed by pushing them up and down (see Figs. 8 to 13).

[0032] According to the above description, when the control member 50 is swung, the coupling between the lamp holder 10 and the positioning seat 30 can be smoothly released. The control member 50 is divided into a pivot plate 501 and two pivot ears 502. One end of each of the two pivot ears 502 is connected to the top surface of the pivot plate 501. The two pivot ears 502 are spaced apart from each other. The other ends of the two pivot ears 502 are pivotally mounted on both sides of the pivot part 303, respectively, and the shaft rod 503 is inserted into the pivot part 303 and the two pivot ears 502. The two pivot ears 502 have a push block 504 on one side facing the lamp holder 10. When a user removes the lamp holder 10 having the lighting device 20, the user first swings the pivot plate 501 toward the lamp holder 10, which swings the two pivot lugs 502 and causes each push block 504 to push the lamp holder 10. The lamp holder 10 moves slightly when pushed. The movement of the lamp holder 10 releases a part of the magnetic attraction force (the magnetic attraction force decreases) between the first magnetic attraction member 1 and the second magnetic attraction member 4, and then applies a downward force to the pivot plate 501 with one of the multiple fingertips. The lighting device 20 includes the lamp holder 10, and when an upward force is applied to the lamp holder 10 to apply two forces in the up and down directions, the lamp holder 10 is pushed upward, and the two engaging protrusions 3 are disengaged from the engagement between the two slots 2, so that the lamp holder 10 can be quickly released from the positioning seat 30 (see Figs. 8 to 13).

[0033] According to the above description, the anti-slip block 305 may be provided at the top end of the pivot plate 501 to prevent the user's finger from slipping off when applying force to the pivot plate 501 to operate it. When the user applies force to the pivot plate 501 with his / her finger to rock it, the magnetic attraction force of a part of the first magnetic attraction member 1 and the second magnetic attraction member 4 is released, and a downward force is applied to the pivot plate 501, the lamp holder 10 mounted on the positioning seat 30 can be removed. The anti-slip block 305 generates a frictional force between the finger and the anti-slip block 305, preventing the user's finger from slipping off when operating it (see FIG. 8).

[0034] In order to prevent the lamp holder 10 from easily coming off the positioning seat when the engagement device of the lighting device according to the second embodiment is actually used, a rib 304 is protruded from one end of the pivot part 303. When the lamp holder 10 and the positioning seat 30 are assembled, the rib 304 is attached to the lamp holder 10 to prevent the lamp holder 10 from coming off the positioning seat 30 before the control member 50 is operated with a finger (see Figs. 9 and 10).

[0035] As can be seen from the above, the engagement device of the lighting device according to the present invention reliably attracts the lamp holder and the positioning seat by the magnetic attraction force between the first magnetic attraction member and the second magnetic attraction member, and further engages and combines the two engagement protrusions with the two slots, thereby preventing the lamp holder and the positioning seat from easily coming off even when an external force is applied through two types of coupling and positioning modes, and enabling the lamp holder and the positioning seat to be quickly and easily assembled without using a complicated structure.
