Description
Technical Field
The present invention relates to a single-body flash device having a pop-up mechanism, and more particularly, to an improvement of a head portion thereof.
Background
In general, as shown in fig. 10, a single-body flash device having a pop-up mechanism for varying an irradiation angle is composed of: a head 101 as a flash light emitting section; a main body 102 configured by a battery, a main control board, and the like; and a boot 103 fixed to a camera body (not shown) and capable of being lifted up, down, left, and right (rotated) as indicated by an arrow by holding the tip of the head 101 with a hand and applying a force (see JP2010-181553A, JP2008-180826 a).
The design of the head 101 is such that: the head 101 is divided into an upper case 1011, a lower case 1012, a fresnel panel 1013 provided at front openings of the upper case 1011 and the lower case 1012, and a cylindrical rear body 1014 provided in a rear space between the upper case 1011 and the lower case 1012 and partially exposed, and thereby is easily disassembled in the case of maintenance at the time of a flash failure.
The rear body 1014 has a main capacitor, a trigger coil, and the like therein, and a pop-up rotor (not shown) is provided at both ends of the rear body 1014.
Fig. 11 is a photograph showing the head 101 of fig. 10. As shown in fig. 11, the upper and lower housings 1011 and 1012 positioned above and below are fixed to a pop-up rotor (not shown) by screws 1015 to be fitted.
Fig. 12 is a photograph for explaining a fitting operation of the upper housing 1011 and the lower housing 1012 in fig. 11, and (a) shows a state before the upper housing 1011 and the lower housing 1012 are fitted, and (B) shows a state after the upper housing 1011 and the lower housing 1012 are fitted. That is, as shown in fig. 12 a, a rib (hook) 1016a is provided at a position outside the upper case 1011 and near the pop-up rotor (not shown), and an engagement hole 1016b is provided at a position near the pop-up rotor of the lower case 1012. As shown in fig. 12 (B), the hook structure 1016 is configured by fitting the hook 1016a into the engagement hole 1016B. Next, the upper housing 1011 and the lower housing 1012 are fixed to the pop-up rotor by the screws 1015.
Thus, the fitting force of the upper housing 1011 and the lower housing 1012 is maintained by the screw 1015 fixed to the pop-up rotor inside and the hook structure 1016 at a position close to the pop-up rotor.
However, in the conventional single-body flash apparatus of fig. 10, since the space for the pop-up rotor in the vicinity of the inside of the head 101 is small, the hook 1016a of the hook structure 1016 in the vicinity of the pop-up rotor cannot be made high, and the hook function of the hook structure 1016 is small. Therefore, in the case of performing maintenance in the event of a flash failure, the hooks 1016a of the hook structure 1016 may be bent to lose the hooking function. As a result, there are problems as follows: a gap is generated between the upper housing 1011 and the lower housing 1012, and the fitting force of the upper housing 1011 and the lower housing 1012 is reduced.
Further, since the distal end portion of the head 101 is gripped and sprung up and down in normal use, a load is likely to be generated on the hook 1016a that engages the upper housing 1011 and the lower housing 1012. Therefore, as described above, there are problems as follows: a gap is generated between the upper housing 1011 and the lower housing 1012, and the fitting force of the upper housing 1011 and the lower housing 1012 is reduced.
Further, if the hook action of the hook structure 1016 becomes small and a gap is generated between the upper housing 1011 and the lower housing 1012, the upper housing 1011, the lower housing 1012, and the bound rotor are fixed only by the screw 1015, and a load applied to the screw 1015 increases at the time of bound operation. As a result, the following problems also exist: the screw 1015 is broken or loosened, and the fitting force between the upper housing 1011 and the lower housing 1012 is further reduced.
Disclosure of Invention
In order to solve the above problem, a single-body flash device of the present invention includes a head portion having: an upper housing; a lower case located below the upper case; a Fresnel panel positioned at the front openings of the upper and lower cases; a cylindrical rear body located in a rear space between the upper case and the lower case; and a 1 st pop-up rotor and a 2 nd pop-up rotor respectively located at both ends of the rear body, wherein the single body flash device includes: a 1 st rib provided on an inner side of the lower case side of the upper case so as to face the 1 st pop-up rotor; a 2 nd rib provided on the inner side of the upper case side of the lower case so as to face the 1 st pop-up rotor; a 3 rd rib provided on an outer side of the 1 st pop-up rotor on the upper case side; and a 4 th rib provided on the outer side of the 1 st flip-up rotor on the lower case side, wherein the 1 st rib and the 2 nd rib are adjacent and opposed to each other to form a 1 st hook, the 3 rd rib and the 4 th rib are separated to form a 1 st engagement groove, and the 1 st hook is engaged with the 1 st engagement groove to form a 1 st hook structure. Thus, the upper case and the lower case are fitted to each other by the 1 st hook structure formed by providing the 1 st engagement groove in the 1 st pop-up rotor.
According to the present invention, the engagement force between the upper case and the lower case can be maintained high by the hook structure in which the engagement groove is provided in the pop-up rotor. That is, since the hook structure rotates together with the pop-up rotor at the time of pop-up, the load of the upper case and the lower case can be reduced, and therefore, deformation is less likely to occur, and a gap is less likely to occur between the upper case and the lower case. Further, since the engaging groove of the hook structure is provided in the pop-up rotor, the height of the hook structure can be increased. Therefore, even when maintenance is performed at the time of a flash failure, the hook is not easily bent, and as a result, the fitting force of the hook structure can be maintained large.

Detailed Description
Fig. 1 is a perspective view showing an embodiment of a head of a single-body flash device of the present invention, fig. 2 is a side view of the head of fig. 1, fig. 3 is an exploded side view of the head of fig. 1, and fig. 4 is a front view of the head of fig. 1. In fig. 1, the main body and the boot are the same as the main body 102 and the boot 103 in fig. 10, and therefore are omitted.
In fig. 1 to 4, the design of the head is as follows: the head is divided into an upper case 1, a lower case 2 located below the upper case 1, a fresnel panel 3 located at front openings of the upper case 1 and the lower case 2, and a cylindrical rear body 4 located in a rear space between the upper case 1 and the lower case 2 and partially exposed. The upper case 1 and the lower case 2 sandwich the pop-up rotors 5-1 and 5-2 (5-2 is shown in fig. 3) and are fixed by a screw 6 and a hook structure described later to be fitted.
Fig. 5 (a) shows a perspective view of the pop-up rotor of fig. 1 to 4, (B) is an enlarged perspective view of one of the pop-up rotors of (a), and (C) is an enlarged perspective view of the other of the pop-up rotors of (a).
As shown in fig. 5 (B), ribs 5-1a and 5-1B are provided on the outer side of the pop-up rotor 5-1. In this case, the rib 5-1a faces the upper case 1, and the rib 5-1b faces the lower case 2. In addition, 5-1c is a threaded hole for the screw 6. On the other hand, as shown in fig. 5 (C), ribs 5-2a, 5-2b are provided on the outside of the pop-up rotor 5-2. In this case, the rib 5-2a faces the upper case 1, and the rib 5-2b faces the lower case 2. In addition, 5-2c are threaded holes for screws 6.
Fig. 6 shows a cross section along the line VI-VI in fig. 2, (a) is an overall cross section, (B) is a partially enlarged cross section of (a), and further, fig. 7 shows a cross section along the line VII-VII in fig. 4, (a) is an overall cross section, and (B) is a partially enlarged cross section of (a). In fig. 6 (a), the rear body 4 sandwiches the main capacitor 7, the trigger coil 8, and the like.
The hook structure of the present invention will be described with reference to fig. 6 and 7.
On the other hand, ribs 5-1a, 5-1b and ribs 5-2a, 5-2b are provided on the outer side of the upper case 1 side and the outer side of the lower case 2 side of the pop-up rotors 5-1, 5-2. In this case, the ribs 5-1a, 5-1b and the ribs 5-2a, 5-2b are resin-molded integrally with the pop-up rotors 5-1, 5-2, respectively. The ribs 5-1a, 5-1b form a 1 st engaging groove for sandwiching a 1 st hook constituted by the rib 1a of the upper case 1 and the rib 2a of the lower case 2 opposed thereto, and the ribs 5-2a, 5-2b form a 2 nd engaging groove for sandwiching a 2 nd hook constituted by the rib 1b of the upper case 1 and the rib 2b of the lower case 2 opposed thereto.
In this way, the 1 st hook structure is constituted by the 1 st hook based on the rib 1a of the upper case 1, the rib 2a of the lower case 2, and the 1 st engaging groove based on the ribs 5-1a, 5-1b of the bound rotor 5-1, while the 2 nd hook structure is constituted by the 2 nd hook based on the rib 1b of the upper case 1, the rib 2b of the lower case 2, and the 2 nd engaging groove based on the ribs 5-2a, 5-2b of the bound rotor 5-2.
The non-opposed surfaces of at least 1 of the opposed hook ribs 1a, 1b, 2a, 2b and the engagement groove ribs 5-1a, 5-1b, 5-2a, 5-2b are inclined, and the non-opposed surfaces are surfaces of the at least 1 rib which are not opposed to the engagement surfaces between the 1 st and 2 nd hooks and the 1 st and 2 nd engagement grooves. For example, in fig. 6 (B) and 7 (B), the surface of the rib 2a not facing the rib 5-1B is defined as an inclined surface 2a ', and the surface of the rib 5-1B not facing the rib 2a is defined as an inclined surface 5-1B'. This can facilitate the assembly of the upper case 1 and the lower case 2. For example, after the ribs 1a and 1b of the upper case 1 are fitted into the engagement grooves of the ribs 5-1a and 5-1b of the pop-up rotors 5-1 and 5-2, the ribs 2a and 2b ride on the ribs 5-1b and 5-2b when the ribs 2a and 2b of the lower case 2 are fitted into the engagement grooves of the ribs 5-1a and 5-1b of the pop-up rotors 5-1 and 5-2. At this time, the rib 2a can easily ride up the rib 5-1b due to the inclined surface 2a 'of the rib 2a or the inclined surface 5-1 b' of the rib 5-1 b.
The above-described hook structure will be further described with reference to fig. 8 and 9.
Fig. 8 shows a state in which the upper case 1 and the lower case 2 are fitted, and the pop-up rotors 5-1, 5-2, the main capacitor 7, the trigger coil 8, and the like are omitted for ease of understanding. As shown in fig. 8, the rib 1a of the upper case 1 and the rib 2a of the lower case 2 are close to and face each other to constitute the 1 st hook.
Fig. 9 also shows a state in which the upper casing 1 and the lower casing 2 are fitted to each other, and for ease of understanding, only the pop-up rotor 5-1 is illustrated without the main capacitor 7 and the like. As shown in fig. 9, the 1 st hook formed by the rib 1a of the upper case 1 and the rib 2a of the lower case 2 is completely fitted into the 1 st engagement groove formed by separating the rib 5-1a and the rib 5-1b of the pop-up rotor 5-1.
In this way, the hook structure in which the engagement grooves (ribs 5-1a, 5-1b, ribs 5-2a, 5-2b) are provided in the pop-up rotors 5-1, 5-2 can keep the fitting force of the upper case 1 and the lower case 2 large. That is, since the hook structure of the present invention rotates together with the pop-up rotors 5-1 and 5-2 at the time of pop-up, the load of the upper case 1 and the lower case 2 can be reduced, and thus, deformation is not easily generated, and a gap is not generated between the upper case 1 and the lower case 2. Further, since the engaging grooves (ribs 5-1a, 5-1b, ribs 5-2a, 5-2b) of the hook structure are provided in the pop-up rotors 5-1, 5-2, the height of the hooks ( ribs 1a, 2a, ribs 1b, 2b) of the hook structure can be increased. Therefore, even when maintenance is performed at the time of a flash failure, the hook is not easily bent, and as a result, the fitting force of the hook structure can be maintained high. Further, the load acting on the screw 6 is reduced by the hook structure, and the screw 6 can be prevented from being damaged or loosened.
