Description

The present invention relates to a tripod mount and a tripod mount unit.

There are cases where a camera lens barrel is fixed to a tripod via a tripod mount to take pictures. However, when transitioning from shooting using a tripod to hand-held shooting, the tripod mount gets in the way. Additionally, it takes time to remove the tripod mount from the tripod, and it may not be possible to smoothly transition to handheld shooting. Furthermore, since the tripod mount protrudes from the lens barrel, there are problems such as poor portability and poor storability in a bag. In order to solve such problems, a tripod mount is known that is configured to be detachably attached to a base ASSY that is attached to a tripod and a lens ASSY that holds a lens barrel.

The above tripod mount, for example, has a dovetail on the lens ASSY and a dovetail on the base ASSY, and by tightening the elastic base ASSY with an adjustment screw, the dovetail on the lens ASSY and the dovetail on the base ASSY can be adjusted. A tripod mount is known that fixes a base ASSY and a lens ASSY by fitting them together. In this tripod mount, a protrusion protruding from the base ASSY is engaged with a screw hole in the ring ASSY to prevent it from falling off (see, for example, Patent Document 1).

In addition, on the above tripod mount, place the dovetail part of the lens ASSY into the dovetail groove of the base ASSY, and while turning the adjustment screw, shift the block with the dovetail groove on the base ASSY to one side to fix the base ASSY and the lens ASSY. Tripod mounts are known. This tripod mount has a mechanism that prevents it from coming off, and the tripod mount cannot be separated when the adjustment screw is loosened, but the mechanism can be released by pressing the adjustment screw (for example, Patent Document 2, (See 3).

Furthermore, the above-mentioned tripod mount has a screw hole in the ring of the lens ASSY, and a fixing screw attached to the base ASSY is engaged with the screw hole to fix the base ASSY and the ring ASSY. (For example, see Patent Document 4).

The base plate 130 includes a plate surface 131 that comes into contact with the bottom surface of the fixing member 420 that moves along the first direction when the ring ASSY 400 is attached, and a boss portion 132 that extends downward from the bottom surface of the plate surface 131. . An inclined groove 133 into which a lock plate 280 for locking the boss portion 132 is inserted is provided in the intermediate portion of the boss portion 132 . Below the inclined groove 133 of the boss portion 132, there is a male thread 134 (corresponding to the "first threaded part" in the claims) that engages with a female thread (corresponds to the "second threaded part" in the claims) 321 of the knob 320, which will be described later. (equivalent to "threaded part") is formed. The tip of the boss portion 132 is provided with a rib 135 that locks a retaining screw 340 that prevents the knob 320 from coming off, which will be described later.

The fixed plate 150 (corresponding to the "second member" in the claims) supports the base plate 130 in a first direction, and is movable in the first direction as the base plate 130 moves in the first direction. It is. Furthermore, the fixed plate 150 has a mutually symmetrical shape and includes a first fixed plate section 150A and a second fixed plate section 150B, which are a pair of members disposed facing each other.

The first fixing plate part 150A and the second fixing plate part 150B constitute a receiving surface 151 for receiving the plate surface 131 of the base plate 130 and one side of the dovetail groove 155, and the first dovetail part 422A of the fixing member 420 , a first dovetail groove 155A and a second dovetail groove 155B that fit into the second dovetail 422B, respectively.

Further, on the opposite side of the receiving surface 151 of the fixed plate 150, there is a protrusion shape having a surface that comes into contact with the bottom surface of the base guide 240 when the ring ASSY 400 is attached, and an inclined surface 153 that follows the inclined portion 241 of the base guide 240. 160 is arranged.

The first fixed plate part 150A and the second fixed plate part 150B are housed in the storage groove 113 of the tripod mount base 110 while facing each other and sandwiching the boss part 132 of the base plate 130, and are integrated with the base plate 130. Thus, a dovetail groove 155 is formed. The dovetail groove 155 allows the first fixing plate part 150A and the second fixing plate part 150B to be attached to the base ASSY 100 by a spring B170 inserted into a hole provided on the side surface of the protrusion-shaped part 160 of the fixing plate 150. When they are not attached, they are pressed against each other in the storage groove 113 of the tripod mount base 110 in a direction that widens the width of the dovetail groove 155.

The washer 190 is inserted into the boss portion 132 of the base plate 130 and placed under the fixing plate 150. Spring A200 is inserted into boss portion 132 of base plate 130 and placed below washer 190. Spring A200 is in contact with the bottom surface of storage groove 113 of tripod seat base 110, and lifts washer 190, fixed plate 150, and base plate 130 upward when ring ASSY 400 is not attached to base ASSY 100.

The base guide 240 is composed of a pair of left-right symmetrical members, and is arranged below the washer 190, the fixing plate 150, and the base plate 130 described above. Further, each member of the base guide 240 has an inclined portion 241 that comes into contact with the inclined surface 153 of the fixed plate 150 when the fixed member 420 is locked. When the inclined surface 153 of the fixed plate 150 comes into contact with the inclined part 241 of the base guide 240, the downward movement of the washer 190, the fixed plate 150, and the base plate 130 is restricted. Further, since the inclined portion 241 of the base guide 240 is inclined toward the center as it goes downward, as the fixed plate 150 moves downward, the two plate portions 150A and 150B that constitute the fixed plate 150 They are pressed in a direction closer to each other. As a result, the first dovetail groove 155A and the second dovetail groove 155B of the two fixing plate parts 150A and 150B more firmly sandwich the first dovetail 422A and second dovetail 422B of the fixing member 420.

As explained above, when the ring ASSY 400 is not attached to the base ASSY 100, the width of the dovetail groove 155 is widened while lifting the washer 190, the fixed plate 150, and the base plate 130 due to the action of the spring A200 and the spring B170. is maintained. When the knob 320 is open, the washer 190, the fixed plate 150, and the base plate 130 are lifted off the base guide 240 by a certain stroke.

The knob 320 is inserted from the outside of the base ASSY 100, and as described above, the knob 320 has a female thread 321 (corresponding to the "first threaded part" in the claims) that is threaded into the male thread 134 (corresponds to the "first threaded part" in the claims). (equivalent to "second threaded part"). That is, a female screw 321 that engages with a male screw 134 of the base plate 130 is provided at the center of the knob 320 . The knob 320 has irregularities on its outer peripheral surface so that it can be easily rotated and operated by the user's fingers.

The knob 320 has a hole and a screw hole on its side, into which a retaining screw 340 is inserted. Since the male screw 134 of the base plate 130 has a certain length, the distance to the base plate 130 can be adjusted by a certain amount depending on the position where the retaining screw 340 contacts the base plate 130. Furthermore, when the knob 320 is loosened, the retaining screw 340 comes into contact with the rib 135 of the base plate 130, thereby preventing the knob 320 from coming off from the boss portion 132.

The holder 300 is inserted into a horizontal groove 115 provided on the back surface of the tripod seat base 110, and can be pressed from the outside along a third direction intersecting the first direction and the second direction of the tripod seat base 110. In this embodiment, the "second direction" is a direction that intersects the first direction, and is the left-right direction. Further, the "third direction" is a direction that intersects the first direction and the second direction, and in this embodiment, it is the front-rear direction.

The holder 300 includes a pressing surface 301 that is pressed by a user, and a connecting portion 302 that connects to the pressing surface 301. A pair of springs C260 are attached to the side surfaces of the connecting portion 302, and a hole 303 through which the boss portion 132 of the base plate 130 passes is provided in the center of the connecting portion 302. When the holder 300 is not pressed, it is biased rearward by the biasing force of the spring C260. The holder 300 is positioned by the lock plate 280, and the boss portion 304 of the connecting portion 302 fits into the positioning hole 283 of the lock plate 280.

The lock plate 280 has a positioning hole 283 for the holder 300 and is attached to the holder 300. The lock plate 280 locks the boss portion 132 of the base plate 130 in a state where the fixing member 420 is locked. That is, the hole 281 of the lock plate 280 is provided with an inclined surface 282 that engages with the inclined groove 133 of the boss portion 132 when the fixing member 420 is locked.

(installed)
Next, a mechanism for attaching the ring ASSY 400 to the base ASSY 100 will be described with reference to FIGS. 6 and 7. FIG. 6 is a sectional view of the ring ASSY 400 of the tripod mount 1 according to Embodiment 1 not attached to the base ASSY 100, and FIG. 7 is a sectional view of the tripod mount 1 of the first embodiment with the ring ASSY 400 attached to the base ASSY 100. be.

To attach the ring ASSY 400 to the base ASSY 100, first insert the outer peripheral edge of the boss seat 411 of the ring ASSY 400 with the lens barrel attached into the opening 111 of the base ASSY 100. This guides the movement of the fixing member 420 to the center of the dovetail groove 155. When the fixing member 420 comes into contact with the plate surface 131 of the base plate 130, the fixing member 420 and the base plate 130 are moved together in the first direction (downward in the first embodiment) due to the weight of the lens barrel attached to the ring ASSY 400. direction).

When the ring ASSY 400 is not attached to the base ASSY 100, the width of the dovetail groove 155 is widened as shown in FIG. 6, so that the dovetail portion 422 can be inserted into the dovetail groove 155.

As the fixing member 420 descends, the base plate 130, the fixing plate 150, and the washer 190 descend against the urging force of the spring A200 until the upper surface of the base guide 240 and the lower surface of the fixing plate 150 come into contact. After the lower end of the inclined surface 153 of the fixed plate 150 contacts the upper end of the inclined portion 241 of the base guide 240, the inclined surface 153 of the fixed plate 150 descends while sliding along the inclined portion 241 of the base guide 240. I will do it. At this time, since the inclined surface 153 of the fixed plate 150 is descending toward the center, as shown by the arrow in FIG. The plate portions 150B move toward each other in the second direction.

As a result, the width of the dovetail groove 155 becomes narrower, and the dovetail portion 422 comes into close contact with the dovetail groove 155 and locks the fixing member 420 by sandwiching it from the second direction.

As described above, the opening 111 of the base ASSY 100 and the outer periphery of the boss seat 411 of the ring ASSY 400 fit together, the dovetail portion 422 is fixed to the dovetail groove 155, and the ring ASSY 400 is stabilized in a state fixed to the base ASSY 100. .

Further, as shown in FIG. 7, in a state where the fixing plate 150 locks the fixing member 420, the lock plate 280 locks the boss portion 132. More specifically, the inclined groove 133 provided in the boss portion 132 of the base plate 130 fits into the inclined surface of the lock plate 280, thereby preventing the base plate 130 from floating up and locking it. This can prevent accidental falling off.

Furthermore, as shown in FIG. 8, by turning the knob 320 while the fixing plate 150 locks the fixing member 420, the rib 135 at the tip of the base plate 130 and the retaining screw 340 fit together, preventing accidental falling off. can be prevented.

As shown in FIG. 9, in the locked state, the holder 300 holds the lock plate 280 in a third direction intersecting the first direction and the second direction, and locks the lock plate 280 along the third direction. The plate 280 is biased in a direction to lock the boss portion 132. That is, both the holder 300 and the lock plate 280 are urged rearward (rightward in FIGS. 9 and 10) by the urging force of the spring C260. In this state, the inclined surface 282 provided in the hole 281 of the lock plate 280 fits into the inclined groove 133 of the boss portion 132.

To remove the ring ASSY 400 from the base ASSY 100 from the state shown in FIG. 9, press the holder 300 while lifting the ring ASSY 400. The holder 300 can be pressed from the outside along a third direction (in this embodiment, the front-back direction). As shown in FIG. 10, when the holder 300 is pushed forward against the biasing force of the spring, the lock plate 280 attached to the holder 300 also slides forward. As a result, the inclined groove 133 of the boss portion 132 and the inclined surface 282 provided in the hole 281 of the lock plate 280 are disengaged from each other. At this time, if the ring ASSY 400 is lifted, the dovetail groove 155 is opened in the second direction, so the dovetail portion 422 can easily pass through the dovetail groove 155.

According to the configuration of this embodiment, the second tripod mount unit (ring ASSY) can be attached to the first tripod mount unit (base ASSY) in one action using an external force during attachment, such as the weight of the lens barrel. It can be carried out.

The spring 670 has one end inserted into a spring hanging hole of the lock disc 650 and passed through the lock disc shaft 690. The other end of the spring 670 is passed through a spring hanging hole in the slide plate 630. As a result, when the lock is released, the spring 670 pushes the slide plate 630 upward while regulating the rotation of the lock disk 650, thereby maintaining the released state. At the time of installation, the slide plate 630 is pushed downward by the boss portion 505, thereby releasing the rotation restriction of the lock disk 650, the lock disk 650 rotates, and the claw portion 652 suppresses the opening 506 of the fixing member 503. It generates a force that keeps pulling you in. The locking mechanism will be described later with reference to FIGS. 17 to 21.

Lock disc shaft 690 passes through tripod seat base 610 and lock disc 650. The main body of the lock disk 650 is rotatably provided around a lock disk axis 690 along the third direction. The third direction is perpendicular to the second direction. In this embodiment, the second direction is the front-back direction, and the third direction is the left-right direction.

The retaining screw A710 prevents the lock disc shaft 690 from coming off by inserting the retaining screw A710 after passing the lock disc shaft 690 through the hole in the tripod seat base 610.

The knob 750 is inserted from the outside of the tripod mount base ASSY 600. The knob 750 is inserted from the bottom side of the tripod mount base 610 through a screw hole. The knob 750 is provided with a groove for restricting movement by the retaining pin 730.

After inserting the knob 750, the retaining pin 730 is inserted through a hole on the side of the tripod mount base ASSY 600, and prevents the knob 750 from coming off and restricts the amount of movement.

The retaining screw B760 is inserted into the retaining pin hole after the retaining pin 730 is inserted. This prevents the retaining pin 730 from falling off.

(When installed)
