Cloud platform

Technical Field

The present invention relates to a head mounted on a tripod apparatus such as a camera tripod.

Technical Field

A conventional pan/tilt head, for example, as shown in fig. 7, has a tilt rotor 1 as a rotor that is rotatably adjustable about a rotation center axis that coincides with the horizontal direction. The tilt unit 1 is provided with a camera attachment 2 that is integrated with the tilt unit 1 and revolves around a rotation center axis.

In the pan/tilt head shown in fig. 7, for example, the base platform 3 is operated to rotationally adjust the tilt rotating body 1 in one direction (counterclockwise direction in fig. 7), and the camera attachment body 2r is located at a position higher than the upper end portion 1a of the tilt rotating body 1 in a substantially horizontal state as a whole in a state where the camera attachment body 2 is set at the 1 st position (solid line position in fig. 7).

Further, for example, when the base flat bar 3 is operated to rotationally adjust the tilt rotating body 1 in the other direction (clockwise direction in fig. 7) and the camera attachment body 2 is set at the 2 nd position (position shown by two-dot chain line in fig. 7), one side portion (left half portion in fig. 7) of the camera attachment body 2 is located at a position higher than the upper end portion 1a of the tilt rotating body 1 and the other side portion (right half portion in fig. 7) of the camera attachment body 2 is located at a position lower than the upper end portion 1a of the tilt rotating body 1.

However, in the configuration of the conventional pan/tilt head shown in fig. 7 described above, even if the camera attachment body 2 is set at the 2 nd position, half of the camera attachment body 2 inevitably protrudes upward from the tilt rotating body 1, and the pan/tilt head cannot be sufficiently downsized.

For example, when the pan/tilt head is set on a tripod and then put in a backpack, the portion of the camera attachment body 2 protruding from the tilt rotating body 1 may become an obstacle and may be difficult to put in the back.

Further, when the pan/tilt head is placed indoors while being mounted on a tripod, for example, a portion of the camera mounting body 2 protruding from the tilt rotating body 1 may become an obstacle, and the place for placing the camera mounting body may be limited.

Disclosure of Invention

In view of the above-described problems, an object of the present invention is to provide a pan/tilt head that can secure a sufficient photographing height when in use and can be sufficiently miniaturized when not in use.

The holder of the invention has: a rotating body which can be rotated and adjusted by taking a rotating central axis in the horizontal direction as a center; a camera mounting body provided on the rolling body, integrally with the rolling body, and rotatable about the rotation center axis of the rolling body, wherein at least a part of the camera mounting body is located at a position higher than an upper end portion of the rolling body in a state where the rolling body is rotationally adjusted in one direction to set the camera mounting body at a 1 st position, and the entire camera mounting body is located at a position lower than the upper end portion of the rolling body in a state where the rolling body is rotationally adjusted in the other direction to set the camera mounting body at a 2 nd position.

The invention can make at least one part of the camera mounting body located at a position higher than the upper end part of the rotating body or make the whole camera mounting body located at a position lower than the upper end part of the rotating body by rotating and adjusting the rotating body, thereby ensuring enough shooting height when in use and being small enough when not in use.

The holder of the present invention further has: a base body connected to the upper end of the foot rest device and provided with the rotating body thereon; a camera mounting body which is provided on the rotating body in a projecting manner, has a shape of an elongated bar extending in a direction intersecting the rotational center axis of the rotating body, and is configured to rotate integrally with the rotating body around the rotational center axis of the rotating body by applying a predetermined force when the rotating body is rotationally adjusted, the rotating body having a base portion rotatably connected to the base and a projecting portion projecting upward from the base portion, the camera mounting body being attached to one side of the projecting portion of the rotating body, the camera mounting body being positioned at a position where a longitudinal direction of the operating handle body and a longitudinal direction of the foot stand device are crossed by rotational adjustment of the rotating body in one direction, the camera mounting body being displaced by a predetermined distance from an upper position of the base body to one side of a projecting side of the operating body in a state where the camera mounting body is set at position 1, and at least a part of the camera attachment body is located at a position higher than an upper end portion of the rotating body, a longitudinal direction of the operating handle body is made parallel to a longitudinal direction of the foot rest device by rotational adjustment of the rotating body in the other direction, the camera attachment body is located at a position deviated by a predetermined distance from a position above the base body toward one side of a projecting side of the operating handle body in a state where the camera attachment body is set at a 2 nd position, and the whole of the camera attachment body is located at a position lower than the upper end portion of the rotating body.

In the present invention, by rotating and adjusting the rotating body having the operating handle body, at least a part of the camera attachment body attached to the projecting portion of the rotating body can be positioned higher than the upper end portion of the rotating body, or the whole camera attachment body can be positioned lower than the upper end portion of the rotating body, so that a sufficient photographing height can be secured when in use, and sufficient miniaturization can be achieved when not in use.

The rotating body of the pan/tilt head of the present invention has a flat surface formed on a surface opposite to a side on which an operation handle body is projected, and the operation handle body is disposed in a state where a longitudinal direction thereof intersects the flat surface perpendicularly.

In the present invention, since the operation handle body is disposed in a state of being perpendicularly crossed with the flat surface of the projecting portion of the rotating body, once the longitudinal direction of the operation handle body is parallel to the longitudinal direction of the foot stool device, the flat surface of the projecting portion of the rotating body becomes one end surface in the longitudinal direction of the foot stool device, and thus the foot stool device can be put into a backpack or the like with a good feeling.

Detailed Description

An embodiment of a pan/tilt head according to the present invention will be described below with reference to the accompanying drawings.

Fig. 1 to 5 show the entire pan head 11 in a landscape position photographing posture with a camera lens facing the front, and the pan head 11 is attached to a pan head mount 13 formed at the upper end of a foot stand device 12 such as a camera tripod to fix a camera not shown, for example, so that the camera lens can be set in any one of the vertical and horizontal directions depending on the position of a subject to be photographed in a state where the foot stand device 12 is fixed by the function of the pan head 11.

As shown in fig. 5, the tripod head 11 has a foot stool connection member 15 having a substantially cylindrical shape with a large diameter at a lower end portion thereof, a screw hole 16 serving as a connection hole is formed in a bottom surface of the foot stool connection member 15, and a male screw, not shown, of the tripod head mounting portion 13 of the tripod head apparatus 12 is screwed into the screw hole 16. A pan turning body 17 as a turning body is provided on the outer peripheral surface side of a pan shaft portion (not shown) of the foot stand connecting member 15, and the turning body 17 is turnable around a turning center axis Y in the vertical direction, which is the vertical direction and coincides with the center axis of the pan shaft portion (not shown).

A cylindrical one connecting portion 18 having an open lower surface is formed on one side portion, i.e., a right side portion, of the pan rotating body 17, and the one connecting portion 18 is rotatable in a state of being fitted to an outer periphery of a pan shaft portion (not shown) of the stand connecting member 15. The other connecting portion 19 such as a substantially cylindrical tilt shaft portion is formed on the other side portion, i.e., the left side portion, of the pan pivoting body 17, and a tilt pivoting body 21 as a pivoting body is attached to the outer peripheral surface side of the other connecting portion 19, and the tilt pivoting body 21 is rotatably adjustable about a rotation center axis X in the horizontal direction in the left-right direction that coincides with the center axis of the other connecting portion 19. The pan rotating body 17 and the stand connecting member 15 constitute a base body 20, and the upper end portion of the stand device 12 is detachably connected to the base body 20.

The tilt rotating body 21 has a substantially cylindrical base portion 22 rotatably fitted to the outer peripheral surface of the other connecting portion 19 of the pan rotating body 17, and the base portion 22 has an arc-shaped lower portion and a substantially cylindrical handle connecting hole 23 having both end surfaces opened at an upper portion. As shown in fig. 2, one opening 23a of the handle connection hole 23 is opened at a position above the rear surface 25, which is one planar side surface of the base portion 22, and is opened obliquely downward toward the rear surface of the pan/tilt head 11, and the other opening 23b of the handle connection hole 23 is opened at a position above the front surface 26, which is the other planar side surface opposite to the base portion 22, and is opened obliquely upward toward the front surface of the pan/tilt head 11. However, the lower ends of the front and rear surfaces 25 and 26 of the base portion 22, which are parallel to each other, are connected to both ends of the lower surface 27 of the semi-arc curved surface.

Further, an upper end portion, i.e., a base end portion, of a pan handle 31 as an operation handle body is inserted into the handle connection hole 23 of the base body 22 and is rotatably connected thereto, and a portion other than the base end portion of the pan handle 31 projects obliquely downward in a predetermined direction, i.e., from the rear surface 25 side of the tilt rotating body 21.

The pan handle 31 is formed in an elongated bar shape having a circular cross section and extending in a direction intersecting the rotation center axis X of the tilt rotor 21, and a gripping member 32 is fixed to a lower end portion, i.e., a distal end portion.

The pan handle 31 holds the holding member 32, and by a turning operation of rotating in the circumferential direction, the tilt turning body 21 can be fixed to or released from the pan turning body 17. The pan handle 31 grips the grip member 32, and moves the tip end side up and down and left and right about the base end side by a revolving operation of the revolution, thereby allowing the tilt rotor 21 to revolve up and down and back and forth about the revolution central axis X and allowing the pan rotor 17 to revolve horizontally and left and right about the revolution central axis Y along with the tilt rotor 21.

The tilt rotating body 21 has a projecting portion 33 projecting upward from the upper side of the base portion 22, that is, a portion near the handle attachment hole 23 of the base portion 22, and the projecting portion 33 is formed integrally with the base portion 22.

As shown in fig. 3 and 4, the protruding portion 33 has a connecting portion 35 having a short length and a semi-conical shape, and the cross-sectional shape of the connecting portion 35 is a rounded shape having one horizontal side at the lower portion. One end surface in the longitudinal direction of the connecting portion 35 is an inclined surface 36 that is inclined from the upper end toward the lower end toward the front of the pan/tilt head 11, the inclined surface 36 of the connecting portion 35 is flush with the front surface 26 of the base portion 22, and a flat surface 37 is formed on the inclined surface 36 and the front surface 26. The flat surface 37 of the tilt turning body 21 is disposed so as to intersect perpendicularly with the longitudinal direction, which is the axial direction of the pan handle 31.

The other end surface in the longitudinal direction of the connecting portion 35, which is a part of the projecting portion 33, is a vertical surface 38 extending in the vertical direction, and as shown in fig. 6, a stem portion 39, which is a cylindrical attachment portion, is integrally formed on the vertical surface 38 in a projecting manner. A screw hole 40 is formed in the vertical surface 38 of the connecting portion 35 at a position inside the upper shaft portion 39. A cylindrical expanding member 48 is coaxially fixed to the distal end portion of the spindle portion 39, and the spindle portion 39 and the expanding member 48 are integrated to constitute the side tilt shaft 30.

The camera mounting body 41 is mounted on the outer peripheral surface side of the side-tilt shaft 30 within a predetermined range, for example, 180 degrees, around the center axis of the side-tilt shaft 30, and is rotatably adjustable. As shown in fig. 2, the side tilt axis 30 is disposed at a position above the center portion in the width direction of the base body 20, that is, the center portion in the left-right direction of the pan/tilt head 11, when viewed from one side, that is, the rear of the pan/tilt head 11.

The camera mounting body 41 has, for example, a tilt table 42 of a snap shoe type (クイツクシユ - タイプ) and a lock knob 43, and the knob 43 is an operation body that is operated when the side tilt table 42 is fixed to the tilt rotary body 21.

As shown in fig. 2, the side-tilting stand 42 can tilt in either of the left and right directions of the pan/tilt head 11 from a horizontal position attitude in which the camera is held horizontally, and can set a horizontal position attitude, a right-standing position attitude, and a left-standing position attitude in accordance with a subject.

The side-inclined stand 42 has a substantially cylindrical fitting connection portion 45 whose both end surfaces are open at a lower portion and a substantially rectangular plate-shaped receiving base portion 46 at an upper portion, and these fitting connection portions 45 are integrally formed with the receiving base portion 46.

As shown in fig. 6, the spindle portion 39 of the side-tilt shaft 30 of the tilt rotary body 21 is rotatably fitted to the inner peripheral side of the fitting connection portion 45 of the side-tilt base 42, and the positioning portion of the tip end portion of the spindle portion 39 is positioned in abutment with the annular step portion 47 formed on the inner surface of the fitting connection portion 45.

An elastically deformable expanding member 48 such as a substantially cylindrical split clip is fitted into the other side of the inner peripheral side of the fitting connection portion 45, and a movable member 49 such as a substantially conical member is attached to an outer edge portion of the expanding member 48. The outer peripheral surface of the movable member 49 is formed with a conical pressing surface 50, an insertion hole 51 penetrating in the axial direction of the branch shaft portion 39 of the boss portion 33 is formed on the center side, a shaft portion 52 of the side tilt lock knob 43 is inserted into the insertion hole 51 and on the inner peripheral side of the fitting connection portion 45, and a tip end screw portion 53 of the shaft portion 52 of the side tilt lock knob 43 is screwed into the screw hole 40 of the connection portion 35 of the boss portion 33.

When the knob portion 54 of the side tilt lock knob 43 is pinched and rotated in one direction, that is, the tightening direction, the movable member 49 moves in a predetermined direction, that is, leftward in fig. 6, together with the side tilt lock knob 43.

In this way, the corresponding conical pressed surface 48a of the expanding member 48 is pressed outward by the pressing surface 50 of the movable member 49, and the expanding member 48 is expanded. As a result, the outer peripheral surface of the expanding member 48 is pressed against the inner peripheral surface of the fitting connection portion 45 of the side inclined table 42, the side inclined table 42 is fixed to the side inclined shaft 30 of the side inclined rotating body 21 via the inclination locking knob 43, and the rotation of the side inclined table 42 with respect to the side inclined shaft 30 of the inclined rotating body 21 is restricted to be in the locked state.

When the knob 54 that grips the side tilt lock knob 43 is rotationally operated in the other direction, i.e., in the tightening release direction, the movable member 49 moves in the predetermined direction, i.e., rightward in fig. 6, together with the side tilt lock knob 43.

Thus, the pressing of the pressing surface 50 of the movable member 49 is released, and the expanding member 48 returns to the original shape. As a result, the pressure-contact state between the outer peripheral surface of the expanding member 48 and the inner peripheral surface of the fitting connection portion 45 of the side slope 42 is released, and the fixed state between the side slope 42 and the tilt rolling body 21 is released. However, the fixing device 55 for fixing the side-tilt table 42 and the tilt turning body 21 is constituted by the side-tilt locking knob 43, the movable member 49, and the like.

The receiving base 46 of the side-tilting base 42 has a storage recess 56 formed on the upper surface side thereof, and a base 57 such as a substantially rectangular plate-like shoe (シユ one) corresponding to the storage recess 56 is detachably fitted into the storage recess 56.

The camera stand 57 after being mounted has a screw 59 in the vertical direction at the center position, and is fixed to the side-tilting stand 42 by a cam lever 60 rotatably supported on a support shaft 58 of the receiving stand 46. The cam lever 60 is operated to rotate in a predetermined direction about the support shaft 58, whereby the camera stand 57 and the side-tilt stand 42 can be released from being fixed to each other. However, when the camera stand 57 is fixed to the side-tilt stand 42, the camera stand 57 mounted on the camera bottom surface, not shown, can be fixed to the side-tilt stand 42 by pushing the camera stand 57 into the housing concave portion 56 of the side-tilt stand 42 from above, and therefore, the camera can be mounted on the pan/tilt head 11 by one operation without requiring a turning operation of the cam lever 60.

The following description will be made of a case where the pan head having the above-described configuration is mounted on a stand device of a camera tripod to perform camera shooting.

The camera stand 57 detached from the side-tilt stand 42 is attached to a camera bottom surface, not shown, with screws 59, and the camera stand 57 is pressed into the housing recess 56 of the side-tilt stand 42 and engaged with the housing recess, thereby mounting the camera on the pan/tilt head 11.

Next, the operation side tilt lock knob 43 is turned to release the fixed state between the side tilt table 42 and the tilt turning body 21, and then the side tilt table 42 is turned in a predetermined direction around the side tilt shaft 30 together with the camera while holding the camera by hand according to the subject of photographing, and the camera is set to the landscape position posture, the right-standing position posture or the left-standing position posture.

Further, by rotating the pan handle 31, the opening angle and length of the tripod of the camera tripod are adjusted while rotating and adjusting the tilt rotating body 21 and the pan rotating body 17, and the height of the support column provided on the shaft support portion of the 3 legs so as to be movable up and down is adjusted. Then, the camera lens is set to a predetermined direction according to the photographic subject, and then the shutter of the camera is operated.

Here, for example, when the side tilt table 42 is set in a state in which the camera is in a landscape position posture, the camera attachment 41 is set at the 1 st position, that is, the predetermined use position, by rotationally adjusting the tilt rotary body 21 in one direction (counterclockwise direction in fig. 1) as shown by the solid line in fig. 1 so that the longitudinal direction of the pan handle 31 intersects with the longitudinal direction of the foot rest device 12, that is, the rotational center axis Z along the longitudinal direction of the pan handle 31 intersects with the rotational center axis Y of the pan rotary body 17 at a predetermined angle (for example, the predetermined angle α is 60 degrees as viewed from the side as shown in fig. 1).

At this time, the entire camera attachment body 41 is located at a position shifted by a predetermined distance from the upper position of the base body 20 to one side of the projecting side of the pan handle 31, i.e., to the rear of the pan/tilt head 11. That is, as shown by the solid line in fig. 1, the front end position of the camera attachment body 41 is spaced apart from the rotation center axis Y of the pan rotating body 17 of the base body 20 by a predetermined distance L1 in side view.

In addition, at least a part of the camera mounting body 41, for example, the upper half portion is located higher than the upper end portion 21a of the tilt rotating body 21, and the camera shooting height can be secured. That is, since the projecting portion 33 is formed to project upward from the base portion 22 of the tilt rotor 21, the height of the camera stand 57 of the camera mounting body 41 with reference to the lower end position of the base body 20 is increased by the projecting amount of the projecting portion 33, that is, the extension of the pan head 11, as compared with the conventional pan head shown in fig. 7, and the photographing height of the camera can be sufficiently secured.

When the camera shooting is performed in this state, and the camera is detached from the pan head 11 after the shooting is completed, the camera mounting body 41 is set at the 2 nd position, i.e., the predetermined unused position, by rotating and adjusting the pan handle 31 in the other direction (the clockwise direction in fig. 1) of the tilt rotating body 21 so that the longitudinal direction thereof is parallel to the longitudinal direction of the foot stand device 12, i.e., the rotation center axis Z of the pan handle 31 in the longitudinal direction thereof is parallel to the rotation center axis Y of the pan rotating body 17, as shown by the two-dot chain line in fig. 1.

At this time, the entire camera attachment body 41 is located at a position shifted by a predetermined distance from the upper position of the base body 20 to one side of the projecting side of the pan handle 31, i.e., to the rear of the pan/tilt head 11. That is, as shown by the two-dot chain line in fig. 1, the front end position of the camera attachment body 41 is separated from the rotation center axis Y of the pan rotating body 17 of the base body 20 by a predetermined distance L2 (> L1) in a side view. Such as a length of the determined distance L2 that is approximately 2 times the determined distance L1.

Further, the entire camera mounting body 41 is located at a position lower than the flat surface 37 which becomes the upper end portion of the tilt rotating body 21 without projecting from it, so that the entire pan/tilt head 11 is downsized, and the length dimension of the camera tripod mounting the pan/tilt head 11 is reduced.

In this way, the above-described pan/tilt head 11 adjusts the tilt body 21 using the pan handle 31 by rotation so that at least a part of the camera attachment body 41 attached to the projection 33 of the tilt body 21 is located higher than the upper end portion of the tilt body 21 or the entire camera attachment body 41 is located lower than the upper end portion of the tilt body 21, and therefore, compared with the conventional pan/tilt head shown in fig. 7, a sufficient photographing height can be secured during use and the size can be sufficiently reduced during non-use.

Therefore, not only the height of the photographed subject can be satisfied, but also the stand 11 alone or the stand device such as a tripod can be easily stored and carried when the stand device is put in the backpack, as compared with the conventional structure shown in fig. 7. In addition, when the pan/tilt head 11 is placed indoors alone or after being mounted on a tripod, the storage place is not easily restricted as compared with the conventional structure shown in fig. 7.

Further, since the pan handle 31 is disposed in a state of perpendicularly intersecting the flat surface 37 of the projecting portion 33 of the tilt rotary body 21, once the longitudinal direction of the pan handle 31 is made parallel to the longitudinal direction of the foot stool device 12, the flat surface 37 of the projecting portion 33 of the tilt rotary body 21 becomes one end surface (upper surface in fig. 1) in the longitudinal direction of the foot stool device 12, and therefore, for example, by abutting the flat surface 37 of the pan head 11 against the inner surface of the bag, the pan head 11 can be smoothly put into the backpack by being mounted on the foot stool device such as a tripod.

However, although the above embodiment has been described with respect to the case where the pan head 11 is mounted on a camera tripod, it is possible to secure a sufficient height when used and to achieve sufficient miniaturization when not used, even when used in, for example, a stand with 1 foot or a foot stand device with 4 or more feet.

Possibility of industrial utilization

As described above, the pan/tilt head of the present invention can secure a sufficient photographing height when in use and can be sufficiently miniaturized when not in use, and is suitable for a pan/tilt head for which portability is important.
