2. Description of the Related Art Conventionally, there have been known telescopic devices configured to adjust the length of legs of camera tripods, stepladders, ladders, chairs, etc. (see, for example, Patent Document 1). The telescoping device of Patent Document 1 includes a first leg made of a cylindrical member, a second leg inserted into the first leg, and a second leg provided on the back side in the insertion direction of the second leg. and a length adjustment member. A window is formed in the first leg, and by inserting the locking part through the window and locking the length adjustment member, the second leg can be inserted into the first leg. The position of the direction is defined. FIG. 10 of Patent Document 1 shows a configuration in which a length adjustment member is configured by a plurality of stacked rings, and when the second leg is inserted a predetermined amount into the first leg, When the stopper is inserted between the rings through the window of the first member, the stopper engages the ring and prevents the second leg from moving relative to the first leg. This makes it possible to obtain the desired length.

Japanese Patent Application Publication No. 2005-76819

By the way, when the length of the leg is adjusted using the extension device of Patent Document 1, the leg is divided into a first leg section and a second leg section, so it is possible to avoid some wobbling. I can't do it. Moreover, in the case of the configuration in which the length adjustment member is configured by the rings of Patent Document 1, a hole is formed in the center of the ring, so when the locking part is inserted between the rings, the locking part is There will be no contact with the ring at the center of the ring. That is, even if the locking portion is lengthened in the insertion direction, the only portion that comes into contact with the ring is the radially outer portion of the ring, which may result in poor balance and increased wobbling between the locking portion and the ring. This tends to become a serious problem after long-term use.

Furthermore, in Patent Document 1, since the shaft passes through the ring, when trying to insert the locking part deep into the first leg part, it hits the shaft halfway and cannot be inserted all the way. This also causes a deterioration of the balance, which in turn causes wobbling.

In addition to adjusting the length, there are cases where it is desired to adjust the relative angle between the first member and the second member, and in this case as well, after setting the desired angle, the first member and the second member are adjusted. There is a demand for minimizing backlash with the second member.

The present invention has been made in view of the above, and an object of the present invention is to reduce the wobbling between the first member and the second member when the first member and the second member are made relatively displaceable. .

In order to achieve the above object, in the present invention, a plurality of adjustment members are arranged in the direction of relative displacement between the first member and the second member, and a locking member is inserted between the adjustment members.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings. Note that the following description of preferred embodiments is essentially just an example, and is not intended to limit the present invention, its applications, or its uses.

(Embodiment 1)
FIG. 1 is a front view of a tripod 2 equipped with an adjustment device 1 according to Embodiment 1 of the present invention. The tripod 2 includes a support 3 and a plurality of leg members 5, and is used, for example, when installing a camera, various measuring instruments, etc. at a predetermined height. The strut 3 includes a proximal cylinder member 3a disposed on the proximal side, a small-diameter distal cylinder member 3b inserted into the proximal cylinder member 3a, and fixed to the upper end of the distal cylinder member 3b. A device mounting portion 3c is provided. The above-mentioned camera, measuring equipment, etc. are attached to the equipment attachment part 3c. The device attachment portion 3c is, for example, a pan head or the like.

By moving the distal end cylinder member 3b in the vertical direction with respect to the proximal cylinder member 3a, the height of the device mounting portion 3c can be adjusted. After the distal end cylinder member 3b is moved, the distal end cylinder member 3b can be fixed to the proximal cylinder member 3b by tightening the tightening member 3d to the proximal cylinder member 3a.

A leg member 5 is attached to the lower end of the proximal tube member 3a so that its angle can be adjusted. In this embodiment, a case will be described in which three leg members 5 are provided, but the number of leg members 5 can be set to any number. The three leg members 5 and the mounting structure for attaching the leg members 5 to the support column 3 are the same.

As shown in FIG. 2, a pair of support plates (first members) 4, 4 that support leg members (second members) 5 are provided on the outer circumferential surface of the lower end of the proximal side cylinder member 3a. They are fixed to each other at intervals in the circumferential direction of the end cylinder member 3a. Each support plate 4 extends in the vertical direction and projects horizontally from the outer circumferential surface of the proximal tube member 3a. The pair of support plates 4, 4 are substantially parallel to each other.

The tripod 3 has a bolt 6 that constitutes a support shaft that supports the leg member 5 with respect to the support plate 4. The shaft portion 6a of the bolt 6 is arranged to extend in the horizontal direction. Therefore, the leg member 5 is connected to the support plate 4 so as to be relatively rotatable in the vertical direction. As shown in FIG. 3, each support plate 4 is formed with a support plate side insertion hole 4a through which the shaft portion 6a of the bolt 6 is inserted. Further, a leg side insertion hole 5a is formed in the base end portion of the leg member 5, into which the shaft portion 6a of the bolt 6 is inserted. After inserting the shaft portion 6a of the bolt 6 into the support plate side insertion hole 4a of one support plate 4, the leg side insertion hole 5a of the leg member 5, and the support plate side insertion hole 4a of the other support plate 4, the shaft portion The leg member 5 can be attached to the support plates 4, 4, ie, the proximal cylinder member 3a, by screwing the nut 6b onto the portion of the support plate 6a that protrudes from the other support plate 4. In addition, the code|symbol 7 shown in FIG. 2 and FIG. 3 is a collar installed between the leg member 5 and one support plate 4, and can be provided as needed. As shown in FIG. 3, the collar 7 is formed with a collar-side insertion hole 7a through which the shaft portion 6a is inserted.

In this embodiment, the leg portion 5 can be rotated around the shaft portion 6a until it reaches an arbitrary angle with respect to the support plates 4, 4. This is realized by the regulating device 1. That is, the adjustment device 1 includes a bolt 6, a nut 6b, a support plate side insertion hole 4a formed in the support plate 4, and a leg side insertion hole 5a formed in the leg member 5. Further, the adjustment device 1 includes a fixing mechanism 10 for fixing the leg member 5 which has been rotationally displaced by a predetermined amount with respect to the support plates 4, 4, to the support plate 4. can be fixed at any angle.

The fixing mechanism 10 includes a plurality of adjustment members 11 , a housing member 12 that accommodates the adjustment members 11 , a locking member 13 that is inserted between the adjustment members 11 and locks the adjustment members 11 , and a support plate 4 . The leg member 5 includes an insertion hole 4b and an engagement protrusion (fixing part) 5b formed in the leg member 5. The adjustment member 11 is a member that is separate from the support plate 4 and the leg member 5, and is arranged in a direction in which the leg portion 5 is displaced relative to the support plate 4, that is, in a circumferential direction of the shaft portion 6a. As shown in FIG. 6A, the adjustment member 11 is made of, for example, a cylindrical pin member, and is made of highly rigid metal. A sharpened portion 11a is formed on the distal end side of the adjustment member 11. FIG. 6B shows a modification of the adjustment member 11, and the adjustment member 11 of this modification is composed of a semi-cylindrical pin member. The shape of the adjustment member 11 may be other than a columnar shape or a semi-cylindrical shape, and may be, for example, a prismatic shape, a plate shape, or a columnar shape having an elliptical cross section. The number of adjustment members 11 is not particularly limited, but can be set to, for example, 5 or more, preferably 10 or more. It is preferable to increase the number of adjustment members 11 because it allows for more multi-stage adjustment. Further, the diameter of the adjusting member 11 can be set, for example, in a range of 1 mm or more and 5 mm or less. It is preferable to reduce the diameter of the adjustment member 11 because the adjustment pitch becomes smaller.

The adjustment member 11 is formed to extend continuously from the front side to the back side in the insertion direction of the locking member 13. Further, the adjustment member 11 includes an adjustment member side contact surface 11b that continuously contacts the locking member 13 from the front side to the rear side in the insertion direction. The adjustment member 11 is made of a magnetic material such as steel, for example.

The housing member 12 is separate from the support plate 4 and the leg member 5, and is arranged so as to come into contact with the side surface of the base end of the leg member 5 on the side opposite to the collar 7. The housing member 12 has a circular thick plate shape, and a housing member side insertion hole 12a through which the shaft portion 6a of the bolt 6 is inserted is formed in the center thereof. The housing member 12 is integrated with the leg member 5 by bolts 6 and nuts 6b.

As also shown in FIG. 4A, the housing member 12 is formed with a housing groove 12b for housing the adjustment member 11. The accommodation groove 12b is open on the side surface of the accommodation member 12 on the leg member 5 side, and the adjustment member 11 can be accommodated in the accommodation groove 12b from this opening. The adjustment member 11 is accommodated so that the sharp end 11a of the adjustment member 11 is on the bottom side of the accommodation groove 12b. This accommodation groove 12b extends in an annular shape concentric with the center of the accommodation member side insertion hole 6a, and is located so as to surround the accommodation member side insertion hole 6a. The depth of the accommodation groove 12b is set to be approximately equal to the length of the adjustment member 11, so that the end portion of the accommodated adjustment member 11 does not protrude from the accommodation groove 12b. The width of the accommodation groove 12b is set to be slightly wider than the outer diameter of the adjustment member 11, so that the adjustment member 11 can be easily moved inside the accommodation groove 12b in the direction in which the accommodation groove 12b extends. Moreover, as shown in FIG. 5, the bottom surface of the accommodation groove 12b has an inclined surface 12c. The inclined surface 12c is formed so that the central portion in the width direction of the accommodation groove 12b is the deepest. As shown in FIG. 4A, when a predetermined number of adjustment members 11 are accommodated in the accommodation groove 12b, an empty space is left in the accommodation groove 12b. In other words, the plurality of adjustment members 11 are accommodated so as to leave a part of the accommodation groove 12b in the circumferential direction and fill the other part.

FIG. 4B shows a modification of the housing member 12. In the modified example, the width of the accommodation groove 12b is increased, so that the adjustment member 11 can be disposed offset in the width direction of the accommodation groove 12b. That is, some adjustment members 11 are arranged on the outer side in the width direction of the accommodation groove 12b, and others are arranged on the inner side in the width direction of the accommodation groove 12b. The center of the adjusting member 11 disposed on the outer side is located on the outer side of the center in the width direction of the accommodation groove 12b, and the center of the adjustment member 11 arranged on the inner side is located on the outer side of the center in the width direction of the accommodation groove 12b. is also located inside. Such an arrangement is possible by making the outer diameter of the adjustment member 11 smaller than the width of the accommodation groove 12b.

Although the accommodation member 12 and the leg member 5 are relatively rotatable, since the accommodation member 12 and the leg member 5 are held in abutting state, the adjustment member 11 accommodated in the accommodation member 12 can be held on the leg member 5. Therefore, the accommodation groove 12b of the accommodation member 12 is the first holding part of the present invention. The shape of the accommodation groove 12b is not limited to the illustrated shape.

Note that an elastic material that contacts the adjustment member 11 can also be accommodated in the accommodation groove 12b. By housing the elastic material, it is possible to suppress rattling of the adjustment member 11 within the housing groove 12b. Examples of the elastic material include cushioning materials made of rubber or the like. Furthermore, a magnet (not shown) for attracting the adjustment member 11 may be provided on the bottom surface of the accommodation groove 12b of the accommodation member 12. By attracting the adjustment member 11 to the magnet, it is possible to prevent the adjustment member 11 from coming out from the introduction hole 12d. The magnet can also be provided on the side surface of the housing groove 12b.

As shown in FIG. 3, the housing member 12 is formed with an introduction hole 12d into which the locking member 13 is inserted so as to be continuous with the housing groove 12b. The introduction hole 12d is for introducing the locking member 13 between the adjustment members 11. As shown in FIG. 4A, the introduction hole 12d has a slit shape, and its longitudinal direction coincides with the radial direction of the housing member 12, that is, the width direction of the housing groove 12b. The longitudinal dimension of the introduction hole 12d is set longer than the width dimension of the accommodation groove 12b, and both longitudinal sides of the introduction hole 12d are positioned so as to protrude from the accommodation groove 12b to both sides in the width direction. The introduction hole 12d is formed to penetrate the housing member 12 in the thickness direction.

The side surface of the housing member 12 opposite to the leg member 5 is adapted to abut against the side surface of the support plate 4. An insertion hole 4b into which the locking member 13 is inserted is formed in the support plate 4 located on the side that the housing member 12 comes into contact with. The insertion hole 4b has a slit shape similar to the introduction hole 12d of the housing member 12, and can have the same shape as the introduction hole 12d.

The accommodating member 12 is fixed to the support plate 4 that the accommodating member 12 contacts, so that the accommodating member 12 and the support plate 4 do not rotate relative to each other. The housing member 12 and the support plate 4 can be fixed so as not to move using a fixing method such as welding or concave-convex fitting. The support plate 4 and the housing member 12 are aligned so that the insertion hole 4b of the support plate 4 and the introduction hole 12d of the housing member 12 are aligned.

The engagement protrusion 5b of the leg member 5 protrudes toward the side on which the housing member 12 is disposed, and is immovably integrated with the main body portion of the leg member 5. The engagement protrusion 5b may be formed of a separate member from the main body portion of the leg member 5, or may be integrally formed with the main body portion of the leg member 5. The engagement protrusion 5b is formed in an arc shape centered on the center portion of the leg side insertion hole 5a. The position of the engagement protrusion 5b is set so that when the accommodation member 12 is brought into contact with a prescribed position on the side surface of the leg member 5, the engagement protrusion 5b enters the accommodation groove 12b of the accommodation member 12. There is. Specifically, the circumferential dimension of the engagement protrusion 5b is set shorter than the circumferential dimension of the open portion of the accommodation groove 12b in which a predetermined number of adjustment members 11 are accommodated. Thereby, when the accommodating member 12 is brought into contact with the side surface of the leg member 5, it becomes possible to insert the engagement protrusion 5b into the vacant part (part in the circumferential direction) of the accommodating groove 12b. When the engagement protrusion 5b is inserted into the vacant part of the accommodation groove 12b, a slight gap is formed between the adjustment members 11 in the accommodation groove 12b. This gap is a gap that allows the locking member 13 to be inserted between the adjustment members 11. Note that a plurality of engagement protrusions 5b may be provided intermittently in the circumferential direction.

As shown in FIG. 3, the locking member 13 includes a locking plate portion 13a and an operating portion 13b. The locking plate portion 13a is formed so as to be inserted into the insertion hole 4b formed in the support plate 4 and the introduction hole 12d formed in the housing member 12, and may be made of a metal plate material, for example. . Since the locking member 13 can be held on the support plate 4 by inserting the locking plate portion 13a into the insertion hole 4b, the insertion hole 4b is the second holding portion of the present invention.

The locking plate portion 13a includes a locking member side contact surface 13c that continuously contacts the adjustment member side contact surface 11b from the front side to the back side in the insertion direction. The operating portion 13b is provided at the base end of the locking plate portion 13a, and is a portion that allows the user of the tripod 2 to easily operate the locking member 13 by holding it, for example, by hand. The shape of the operating portion 13b can be any shape, for example, it may be ring-shaped.

(Operation of adjustment device 1)
Next, the operation of the adjustment device 1 will be explained. When the user holds the operating portion 13b of the locking member 13 and pulls out the locking plate portion 13a from the introduction hole 12d of the housing member 12, the locking plate portion 13a comes out from between the adjustment members 11. This allows relative rotation between the leg member 5 and the support plate 4. That is, the leg member 5 is provided with the engagement protrusion 5b, and the engagement protrusion 5b enters the accommodation groove 12b of the accommodation member 12, while the accommodation member 12 is fixed to the support plate 4. When the leg member 5 is rotated with respect to the support plate 4, the engagement protrusion 5b will move relatively in the circumferential direction within the accommodation groove 12b. At this time, since the locking plate portion 13a is not locked to the adjustment member 11, the adjustment member 11 is pushed in the circumferential direction by the engagement protrusion 5b, and the adjustment member 11 moves in the circumferential direction within the accommodation groove 12b. do. This allows the leg member 5 to be rotated to any desired angle. At this time, the locking member 13 may be held by the support plate 4 or may be removed from the support plate 4. Note that the leg member 5 can also be rotated until its tip comes up, and thereby the tripod 2 can be made compact with the leg member 5 in a folded state.

After rotating the leg member 5 to an arbitrary angle, when the locking plate portion 13a of the locking member 13 is inserted into the introduction hole 12d of the housing member 12, the locking plate portion 13a is inserted between the adjusting member 11. It is inserted and locked to the adjustment member 11. Since the locking member 13 is held by the support plate 4, movement of the adjustment member 11 is prevented by the locking member 13 when an attempt is made to rotate the leg member 5. Thereby, the leg member 5 is fixed to the support plate 4 and becomes unrotatable.

When inserting the locking plate portion 13a of the locking member 13 between the adjustment members 11, since the sharpened portion 11a is formed on the distal end side of the adjustment member 11, a gap is created between adjacent adjustment members 11. The tip of the locking plate portion 13a can easily fit between the adjustment members 11. When the locking plate portion 13a is inserted between the adjustment members 11, the adjustment member side contact surface 11b of the adjustment member 11 and the locking member side contact surface 13c of the locking member 13 come into contact. At this time, the adjustment member 11 extends from the front side of the locking plate part 13a in the insertion direction to the rear side, and the adjustment member side contact surface 11b of the adjustment member 11 extends from the front side of the locking plate part 13a in the insertion direction to the rear side. Moreover, the locking member side abutment surface 13c of the locking member 13 is continuous from the front side to the back side in the insertion direction of the locking plate portion 13a, so that when an external force or action is applied, Good balance is maintained when excitation force is applied.

(Operations and effects of embodiments)
As explained above, according to this embodiment, the angle of the leg member 5 with respect to the support plate 4 can be adjusted to any angle, and when the locking member 13 is inserted between the adjustment members 11, the locking member 13 continuously contacts the adjustment member 11 from the front side to the rear side in the insertion direction, the balance is good when an external force is applied or when an excitation force is applied, thereby supporting the leg member 5. Shakiness against the plate 4 can be reduced.

(Embodiment 2)
7 to 10 relate to Embodiment 2 of the present invention. Embodiment 2 differs from Embodiment 1 in that a plurality of adjusting devices 1 can be operated at once by one operating member. Hereinafter, the same parts as in Embodiment 1 will be given the same reference numerals and the explanation will be omitted, and different parts will be explained in detail.

As shown in FIGS. 8 and 9, a plurality of magnets 5c are embedded around the leg side insertion hole 5a in the leg member 5. The magnets 5c are for attracting the adjustment member 11, and are arranged in an arc shape concentric with the center of the leg side insertion hole 5a. The magnet 5c is covered by a covering plate 5d. Two engaging protrusions 5b are provided on the surface of the leg member 5 on the side of the housing member 12, spaced apart from each other in the circumferential direction.
