Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a strobe bounce device, and more particularly to a strobe bounce device that can bounce the light emitting part of the strobe in both horizontal and vertical directions.

In general, a strobe bounce device that holds the strobe light emitting part rotatably in the horizontal and vertical directions so that the bounce angle can be set in any direction is well known, but this type of conventional bounce device Since the light emitting part can always rotate horizontally and vertically at the same time, for example,
When it is desired to bounce the light emitting section only in the horizontal direction or only in the vertical direction at an appropriate angle, there is a drawback that it is difficult to rotate the light emitting section to the desired bounce position.

In view of this, the purpose of the present invention is to rotate the light emitting part in the horizontal or vertical direction by releasing the lock at the normal position using the release member. To provide a bounce device for a strobe, in which locking in a direction is released and the bounce angle in the same direction can be freely set thereafter.

a constitutes a locking part that engages and disengages from the first locked part 34, and the first locked part 29a includes the first locked part formed on the lower surface of the first support member 12. The locking pin 34 can be engaged with the first support member 12 only at a normal position in the horizontal plane. Furthermore, as shown in FIG. 3, at the frontmost end of the first locking member 14, a middle portion of a protruding piece 30, which is formed to protrude forward from the bottom of the U-shape, is bent vertically downward. It is provided as a locking piece 30a constituting the first locking release part, and the locking piece 3
0a passes through the notch 20 of the substrate 11 and reaches below the lower surface of the substrate 11. That is,
With the locking piece 30a fitted into the notch 20, the first locking member 14 is normally moved in the direction of arrow D with respect to the substrate 11 by the biasing force of the torsion spring 27. be.

The first support member 12 is formed by bending a thin plate, and has a horizontal portion 1 disposed parallel to the substrate 11.
It has vertical parts 12b on both sides of 2a. Note that in FIG. 3, illustration of the other vertical portion 12b is omitted. A support cylinder 17 is provided in the horizontal part 12a.
a hole 31 for fitting, two roller penetration windows 32 and 33 bored near the hole 31 at symmetrical positions across the hole 31, and the first locking member 14. A locking pin 34 that engages with the locking portion 29 is provided. The first support member 12 supports the substrate 1
By rotatably fitting the support tube 17 attached to the substrate 1 into the hole 31, the support tube 17 can be rotated horizontally with respect to the substrate 11. This horizontal part 12a
An annular roller holding member 35 made of an elastic thin metal plate is attached to the upper surface of the roller with screws 36 and 37 with its center aligned with the hole 31.
A pair of roller support pieces 38 and 39 are formed on the roller holding member 35 at positions opposite to each other with the center in between, and protrude vertically toward the horizontal portion 12a. is rotatably supported. The roller support member 35 has screws 36 and 37
When the rollers 40 and 41 are fixed to the horizontal portion 12a of the first support member 12, the rollers 40 and 41 penetrate through the windows 32 and 33, respectively, and are pressed against and roll into contact with the upper surface of the substrate 11. . Therefore, when the first support member 12 rotates around the support tube 17, the rollers 40 and 41 roll over the click grooves 19 on the substrate 11, and the click grooves 19 are rotated at predetermined rotation angle intervals. It has come to have a top effect. A hole 43 for rotatably supporting the support member 12 is formed in the vertical portion 12b of the first support member 12 at a position slightly above the center. This hole 43 has a boss portion 44a of the support disk 44.
are fitted, and this support disk 44 has three screws 45
Since the first support member 12 is fixed to the outer surface of the vertical part of the second support member 13 by
The support member 13 is rotatably held on a vertical axis. Further, in the vertical portion 12b of the first support member 12, a window portion 46 for passing through the roller is formed below the hole 43. Vertical part 1
An annular roller holding member 47 made of an elastic thin metal plate is attached to the outer surface of 2b with screws 48 and 49 so that its center coincides with the hole 43. A pair of roller support pieces 50 and 51 protruding toward the vertical portion 12b are formed at opposite positions across the center of the roller holding member 47, and rollers 52 and 53 are rotated on the support pieces 50 and 51. It has become freely supported. When the roller support member 47 is fixed to the vertical portion 12b of the first support member 12 with the screws 48 and 49, one of the rollers 52
is the position of the window part 46, and the other roller 53 is the position of the vertical part 1
The same vertical part 1 is located above the upper end of 2b.
2b, and these rollers 52 and 53 penetrate the vertical portion 13b of the second support member 13 when the second support member 13 is attached to the first support member 12 by the support disk 44. It is in contact with the outer surface. In addition, in FIG. 3, the first support member 12
After the roller holding member 47 is also attached to the vertical part (not shown) of the
The vertical portion 13b of the support member 13 is attached.

The second support member 13 is formed by bending a thin plate to form vertical portions 13b on both sides of a horizontal portion 13a, and is integrally fixed to the rear lower end of the light emitting portion 2 by a screw (not shown). Near the central front end of the lower surface of the horizontal portion 13a, there is a locking portion that constitutes a second locked portion for engaging with the second locking member 15 when the second support member 13 is in a steady state. A piece 54 is fixed and serves to prevent rotation in order to keep the second support member 13 in a fixed position in the vertical plane. The vertical portion 13b has click grooves 55a to 55f on the circumference of the raceway on which the rollers 52 and 53 roll.
is formed. For this reason, the second support member 13
The support disk 44 is inserted into the support hole 4 of the first support member 12.
When the first support member 12 and the rollers 52 and 53 integrated with the first support member 12 rotate in a state where the first support member 12 is held at the position 3, the rollers 52 and 53 roll into contact with the click grooves 55a to 55f, and perform a click stop action at a predetermined angular position. ing.

The second locking member 15 is made of a cylindrical member, and is movably fitted into the support tube 17, and has a locking piece 54 integrated with the second support member 13 at its upper end. An engagement protrusion 15a serving as an engagement portion is provided, and a large diameter flange portion 15b constituting a second unlocking portion is formed at the lower end.

The release member 16 has two elongated holes 57 and 58 formed in the front and back, whose longitudinal directions coincide with the front and back directions, and screws 59 and 59 fitted in the elongated holes 57 and 58, respectively.
60, this release member 16 is attached to the lower surface of the substrate 11 so as to be movable in the directions of arrows C and D. A cutout window 61 is formed between the elongated holes 57 and 58 of the release member 16 to allow the second locking member 15 to pass therethrough. This cutout window 61
is formed to be slightly longer in the front-rear direction, and the upper end surface of the flange portion 15b of the second locking member 15 comes into contact with the left and right sides 16b, 16c, and both sides 16b, 16c is a slope 16 that protrudes downward in a V-shape at the rear position.
b ₀ , 16C ₀ is formed. The front end portion 16a having the elongated hole 57 is connected to the notch 20 on the substrate 11.
It is located at a position corresponding to , and is formed to be slightly wider than the width of the notch 20 . The rear end portion 16d of the release member 16 serves as an operation portion, and is bent downward at a position that protrudes rearward from the rear end of the base plate 11 so as to be easily operated. Further, a pin 62 fixed to the lower surface of the substrate 11 is fitted into the elongated hole 58 of the release member 16, and the pin 62 and the elongated hole 58 are connected to each other.
A return coil spring 64 is stretched between the locking piece 63 formed near the front edge of the holder. Due to the tensile elasticity of the coil spring 64, the release member 16 is normally in the normal position where it has moved in the direction of arrow D, that is, backward, relative to the substrate 11.

A leaf spring 65 is attached to one end of the lower surface of the board 11 near the notch 20 with screws 66 and 67, and the other end of the leaf spring 65 extends to the center of the board 11. The plate spring 65 presses against the lower surface of the second locking member 15 to hold the locking member 15 so that it does not fall and is pressed against the release member 16.

Since the strobe bounce device 1 is configured as described above, in a steady state where the light emitting window of the light emitting unit 2 faces the front as shown in FIG.
The supporting member 12 and the second supporting member 13 are in a steady position with respect to the substrate 11, and each of the supporting members 12 and 13 are
It is in a state where it is engaged with the locking member 14 and the second locking member 15 and cannot be rotated. That is, in this steady state, as shown in FIG. 4A, the locking pin 34 is fitted into the locking groove 29a of the locking portion 29 of the first locking member 14, so that the first support Part 1
2 is in a steady position without being able to rotate, and as shown in FIG.
4 are in abutment with each other, and the second support member 13 is in a steady position without being able to rotate. Therefore, the light emitting section 2 integrated with the second support member 13 is in a locked state in which it cannot be rotated in either the horizontal or vertical direction.

In this locked state, the rear end 16 of the release member 16
It is released by pushing d in the direction of arrow C.
That is, when the release member 16 slides in the direction of arrow C against the tensile force of the return coil spring 64 and reaches the unlocked position, the release member 16 is moved back from the notch 20 of the base plate 11 at the normal position. 16 front end 1
6a moves the position of the notch 20, and the first locking member 1 protrudes from the notch 20 at its distal end surface.
4, the first locking member 14 moves in the direction of arrow C, ie, forward, against the biasing force of the torsion spring 27. Then, the locking portion 29 moves from the position shown by the solid line in FIG. The first support member 12 is rotatable relative to the first locking member 14 and the substrate 11. Therefore,
In this state, the light emitting section 2 can be rotated horizontally through 360 degrees integrally with the first support member 12 and the second support member 13. When the light emitting unit 2 rotates in the horizontal direction, the two rollers 40 and 41 roll into contact with two opposing click grooves 19 on the substrate 11, so that the number of click grooves 19 is arranged at equal angles as shown in the figure. Assuming that there are 12 at intervals, a click stop action will be performed every 30° rotation.
The light emitting unit 2 can be stably set at any horizontal angular position at 30° intervals.

Further, when the release member 16 slides in the direction of arrow C by being pushed by the rear end 16d, the release member 16 is at the normal position on both left and right sides 1 of the cutout window 61.
The second locking member 15, which was fitted into the support cylinder 17 with the flange portion 15b in contact with the flat position of the sides 16b, 16c,
Since the flange portion 15b is pressed down by b ₀ and 16c ₀ and descends against the upward force of the leaf spring 65,
The engagement protrusion 15a of the second locking member 15 retreats from the position where it engages with the locking piece 54, and the second support member 13 becomes rotatable relative to the first support member 12. Therefore, in this state, the second support member 1
The light emitting section 2 integrated with the light emitting section 3 can be rotated in the vertical direction. In the rotating position in a steady state, one roller 52 is in the click groove 55a and the other roller 52 is in the click groove 55a.
3 are fitted into the click grooves 55d, but by rotating the light emitting part 2 vertically upward, only one of the rollers 52 and 53 faces the click grooves at a predetermined rotation position. I started to
The click stop is activated at the same rotational position. That is, when the light emitting section 2 is rotated vertically upward, the rollers 53 first click-stop at a position facing the click groove 55c, and when the light emitting section 2 is rotated further, the roller 52 is click-stopped at a position opposite the click groove 55f. Then, the rollers 53 click-stop at a position opposite to the click groove 55b, and finally the roller 52 click-stops at a position opposite to the click groove 55e. When one of the rollers faces the click groove, the other roller does not face the click groove. thus,
The light emitting unit 2 can have a rotation angle set in five stages, including a normal position where the light emitting window faces the front, and a rotation angle position where the light emitting window faces directly upward.

In this manner, by slidingly biasing the release member 16 in the direction of the arrow C, the first support member 12 and the second support member 13 are simultaneously released from being locked to the substrate 11 in their normal positions. It's getting old.

When rotating the light emitting section 2 horizontally or vertically, the light emitting section 2 is slightly moved horizontally or vertically from the normal position while the release member 16 is pushed in the direction of arrow C as described above. If the release member 16 is rotated by a predetermined angle or more, the release member 16
Even if the release member 16 is moved back in the direction of arrow D by the tensile force of the coil spring 64 when the user releases the hand, the light emitting part 2 is moved to the subsequent appropriate angular position with respect to this slightly rotated direction. can rotate freely.

That is, when the light emitting part 2 is rotated horizontally by a predetermined angle or more while the release member 16 is pushed in the direction of arrow C, the locking pin 34 is deviated from the locking groove 29a of the first locking member 14. As shown in Figure 4B, the first
Since the first locking member 14 is placed in a positional relationship in which it does not engage with the locking member 14, by releasing the hand from the release member 16, the first locking member 14 returns together with the release member 16 in the direction of arrow D. At this time, the first locking member 14 does not engage with the locking pin 34, and the light emitting unit 2 is free to rotate in the horizontal direction until it returns to its normal position with the light emitting window facing the front, and the light emitting unit 2 can be rotated in the appropriate position. You can set the bounce angle. At this time, regarding vertical rotation, as long as the light emitting part 2 is rotated only in the horizontal direction while the release member 16 is pushed in the direction of arrow C, the position of the locking piece 54 will not change.
When the release member 16 is released, the second locking member 15 engages with the locking piece 54 again, and the light emitting part 2 cannot be rotated in the vertical direction and is locked in a steady position. .

Similarly, when the light emitting part 2 is rotated by a predetermined angle or more in the vertical direction while the release member 16 is pushed in the direction of arrow C, the locking piece 54 engages with the engagement protrusion 15a of the second locking member 15. After this, by releasing the release member 16, the second locking member 15 rises and returns to its original position as the release member 16 returns. ,
At this time, the second locking member 15 does not engage with the locking piece 54, and the light emitting unit 2 is free to rotate in the vertical direction until it returns to the normal position where the light emitting window faces the horizontal direction. You can set the bounce angle to the appropriate position. At this time, regarding rotation in the horizontal direction, as long as the release member 16 is pushed in the direction of arrow C and the light emitting section 2 is rotated only in the vertical direction, the position of the locking pin 34 will not change. Release member 16
When the hand is released, the first locking member 14 engages the locking pin 34 again, and the light emitting section 2 cannot be rotated in the horizontal direction and is locked at a normal position.

Therefore, for example, if the light emitting unit 2 is moved only in the horizontal direction,
Alternatively, if you want to bounce only in the vertical direction at an appropriate angle, press the release member 16 as described above and slightly rotate the light emitting unit 2 in the desired direction, then release the release member 16. If the light emitting part 2 is rotated by an arbitrary angle, the light emitting part 2 will be locked against rotation in other directions and will only rotate in the desired direction, so the desired bounce angle position can be achieved. is set quickly and reliably.

In addition, if you want to bounce the light emitting unit 2 to a position rotated at an appropriate angle in the horizontal direction and vertical direction, the light emitting unit 2 can be bounced in either the horizontal direction or the vertical direction while pressing the release member 16 as described above. After slightly rotating the light emitting part 2, the light emitting part 2 can be rotated slightly in the same way in other directions.After this, even if the release member 16 is released, the light emitting part 2 will remain horizontal or vertical. Since the locked state is released and rotation becomes possible in both directions, the light emitting section 2 can be bounced to a desired position by rotating the light emitting section 2 by a desired angle in both the horizontal direction and the vertical direction.

In addition, when bouncing the light emitting part 2, it is of course possible to rotate the light emitting part 2 while keeping the release member 16 pressed. In this case, the light emitting section 2 is rotatable in both the horizontal and vertical directions, and can be bounced to a desired position.

To return the light emitting unit 2 to the normal position, remove your hand from the release member 16 and rotate the light emitting unit 2 horizontally and vertically until it reaches the normal position. The first
The locking member 14 and the first support member 12 engage with each other, and the second locking member 15 and the second support member 1 engage with each other.
3 and returns to the state where rotation is locked in both the horizontal and vertical directions. When the first locking member 14 and the first support member 12 engage with each other, when the light emitting part 2 rotates in the horizontal direction and approaches the normal position, as shown in FIG. 4C, Since the locking pin 34 integrated with the first support member 12 presses the slope 29b at the outer end of the locking portion 29 of the first locking member 14, the locking occurs as the locking pin 34 moves at this time. The portion 29, that is, the first locking member 14 is indicated by the arrow C.
move in the direction. Then, at the normal position, the locking pin 3
4 reaches the position of the locking groove 29a, the first locking member 14 is moved back in the direction of arrow D by the torsion spring 27, and the locking pin 34 is moved again as shown in FIG. 4A.
is fitted into the locking groove 29a, and horizontal locking is completed. In addition, when the second locking member 15 and the second support member 13 engage with each other, when the light emitting part 2 rotates in the vertical direction toward the normal position and approaches the normal position, the second locking member 15 and the second supporting member 13 engage with each other. As shown in FIG. 5B, the locking piece 54 integrated with the second support member 3 comes to abut against the end surface of the engagement protrusion 15a of the second locking member 15, but the second locking Since the member 15 is held by the leaf spring 65, at this time the locking member 15 is pushed down by the locking piece 54 against the force of the leaf spring 65, and the light emitting part 2 is When the stationary position is reached, the engagement between the locking piece 54 and the engagement protrusion 15a at their distal ends is removed, and the locking member 15 is raised by the leaf spring 65, as shown in FIG. 4A. The locking piece 54 engages with the engagement protrusion 15a again to complete the vertical locking.

As described above, according to the present invention, the light emitting part can be kept locked in a normal position, and can be freely rotated in the horizontal and vertical directions by operating the release member in one direction. The bounce angle can be set to the desired bounce angle, and even if you want the light emitting part to bounce only in either the horizontal or vertical direction, it can be kept locked in any direction that does not need to be rotated. This provides excellent effects such as being able to easily and reliably perform a rotation operation to a desired bounce position.
