Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention can be used as a continuous temporary fence by assembling a plurality of members at a work site or a road construction site. As described above, the present invention relates to a temporary fence holding mechanism capable of correcting the inclination angle of the weight.

[0002]

2. Description of the Related Art Conventionally, at a work site or a road construction site, a passerby is prevented from being injured by a passerby entering the construction site, or a person who intrudes into a building without permission is regulated. Therefore, the surroundings have been surrounded by metal fences, plastic fences, and the like.

A conventional temporary fence has been constructed by sequentially connecting fence frames having a net fixed to a frame of about 1 meter in length and width with metal or plastic and holding the connected fence frames vertically to the ground. . When connecting fence frames in this way, fix the bottom of each single fence frame to the pile driven into the ground, or
It was fixed to the ground by fixing it to a metal pipe with a dedicated joint. However, in recent years, due to the convenience of work, heavy weights that can be placed on the ground have come to be used. In the center of this weight, there is a holding hole that can be inserted into the bottom of the fence frame so that the extended legs can be inserted.The weight is set on the ground at equal intervals, and the holding holes for the left and right weights are placed on both sides of the fence frame. He inserted the legs and raised the fence frame vertically and held it.
This temporary fence assembly system that uses a combination of fence frames and weights simplifies temporary work and enables quick assembly of temporary fences at work sites and road construction sites.

In such a temporary fence assembling system which can be easily assembled, if the ground or road on which the weight is set is horizontal, the holding hole opened in the center of the weight becomes vertical, The legs of the fence frame that are inserted into the retaining holes are raised vertically, and the sides of the fence frame can be kept vertical.

However, the ground of road construction and work sites is not always horizontal, and is often inclined or uneven. Therefore, if the weight is placed on the ground as it is, the weight will be inclined according to the inclination or unevenness of the ground. If the legs of the fence frame are inserted into the holding holes of such inclined weights, the fence frame is also inclined with respect to the vertical line according to the inclined angle of the weights. If the temporary fence is used with the fence frame tilted in this way, it causes the temporary fence to fall in the tilted direction, which is dangerous. Also,
When a plurality of fence frames are connected to assemble a temporary fence over a long distance, the temporary fence does not have a straight line shape, and the fence body swings to the left and right as if undulating, resulting in a bad appearance.

[0006]

Thus, from the viewpoint of danger prevention and appearance, the weight holding hole is aligned with the vertical line even when the ground is inclined or uneven. It is preferable that the legs of the fence frame can be held vertically. For this reason, conventionally, the ground on which the weight is placed is dug up to make it horizontal, or the lower surface of the weight is laid so that it becomes horizontal.

However, if the ground is dug up and the weight level is adjusted, it will take time at the construction site of the temporary fence, and the work will not be completed when the temporary fence is assembled. In addition, the method of spreading the sand on the ground to adjust the leveling of the weight is troublesome because post-treatment must be performed when removing the temporary fence.

[0008]

According to the holding mechanism for a temporary fence of the present invention, a plurality of weights to be placed on the ground, a holding hole vertically drilled in the center of the upper surface of each weight, and both sides are provided. It consists of a plurality of frame-shaped fence bodies with extended fixed legs at the bottom of the fence, the fence body is located between the weights, and the fixed legs on both sides are inserted into the holding holes of each weight to create a fence. In a system of temporary fences that can stand up and assemble a continuous temporary fence, this weight consists of an upper weight part and a lower weight part that are slightly columnar and can be separated into upper and lower parts, and the upper surface of the upper weight part Is formed on a plane perpendicular to the vertical line, and a holding hole into which the fixed leg of the fence can be inserted is vertically drilled in the center of this upper surface, and the lower surface of the upper weight part is a vertical line. The upper surface of the lower weight part is formed to be a plane inclined from the vertical line, the lower surface of the lower weight part is formed to be a plane perpendicular to the vertical line, and the upper weight part and the lower weight part are formed vertically. By rotating relative to the line as an axis, even if the lower surface of the lower weight part is not horizontal, the central axis of the holding hole of the upper weight part is adjusted to be vertical. is there.

[0009]

In the present invention, the weight that supports the fence is composed of the upper weight portion and the lower weight portion, and the lower surface of the upper weight portion and the upper surface of the lower weight portion, which are the contact surfaces of the two, with respect to the vertical line. It is formed in the inclined plane.
For this reason, when the upper weight part and the lower weight part are mutually rotated about their central axes, the upper weight part is rotated by the inclined upper surface of the lower weight part, and the upper weight part is rubbed by the inclined angle. Makes a tilt similar to. At this time, if the lower surface of the lower weight portion is placed on the ground with an inclination, the upper weight portion is rotated with respect to the lower weight portion, and the angle formed by the central axes of both is in the direction opposite to the inclination angle of the ground. Adjust so that the angles are the same.

By rotating the upper weight portion with respect to the lower weight portion to adjust the angle between the two and canceling out the inclined angle of the lower weight portion, the central axis of the upper weight portion becomes vertical. Can be corrected as In this way, by rotating the upper weight part and adjusting the angle with the lower weight part, the center axis of the holding hole is oriented in the vertical direction, and how the bottom surface of the lower weight part makes contact with the ground surface. Even if it is tilted, it can be corrected.

On the lower surface of the upper weight portion 12 and on the plane around the mating protrusion 24, meshing teeth 25 are arranged at equal intervals, and each meshing tooth 25 is projected radially around the drainage hole 23. is there. The spacing between the meshing teeth 21 and the spacing between the meshing teeth 25 are set to be the same, and even if the lower weight portion 11 and the upper weight portion 12 are rotated in the circumferential direction, they can be meshed with each other.

FIG. 6 is a plan view of the above-mentioned holding hole 13 viewed from above. The holding hole 13 is composed of four arc-shaped portions and a straight line portion connecting the opposing arc portions, and the four arc-shaped portions include the semicircular portions 30, 31, and the preliminary circular portion 34. , 35. The curvatures of the four arc-shaped portions are formed to have the same diameter, and the diameter of each arc-shaped portion is the same as that of the fixed leg 1 described above.
It is set to be slightly larger than the diameter of 7. The semicircular portions 30 and 31 are spaced apart from the draining hole 23 so as to face each other at the same interval, and linear parallel portions 32 and 33 are continuous so as to connect the tangent lines of the semicircular portions 30 and 31. I am doing it.

Further, a spare circular portion 34 is formed at a position (downward in FIG. 6) slightly apart from the central axis of the semicircular portion 30 so that the circular arc portions overlap.
A preliminary circular portion 35 is formed at a position (upper side in FIG. 6) slightly apart from the central axis of the semicircular portion 31 so that the circular arc portions overlap. Therefore, the holding hole 13 includes the semicircular portions 30, 31, the parallel portions 32, 33, the preliminary circular portion 34,
By 35, the two dumplings arranged in parallel on the left and right have a planar shape in which they are alternately arranged in the vertical direction. The distance between the central axes of curvature of the semicircular portions 30 and 31 is such that the left and right fixed legs 17 and 17 contact the inner walls of the semicircular portions 30 and 31 when the side surfaces of the frame bodies 15 and 15 are brought into contact with each other. Is set to the interval. The distance between the intersections of the semicircular portion 30 and the spare circular portion 34, and the distance between the intersections of the semicircular portion 31 and the spare circular portion 35 are set to be smaller than their respective diameters, and the fixed leg 17 is fixed to the spare circular portion 34.
Even if the fixed leg 17 is inserted into the spare circular portion 35, the semicircular portion 31 is regulated so as not to move to the semi-circular portion 30 even if it is inserted.
It is regulated not to move to.

Next, a case where the weight 1 is used to support the fence 2 on the ground inclined by the angle θ will be described with reference to FIG.

As shown in FIG. 3, the lower weight portion 11 and the upper weight portion 12 are placed with the lower surface of the lower weight portion 11 in contact with the ground 1 whose upper and lower surfaces remain parallel to each other and the ground inclined at this angle θ. Then, the upper surface of the upper weight portion 12 is inclined by the angle θ. As described above, when the ground surface on which the lower surface of the lower weight portion 11 is placed is inclined, the horizontal angle of the upper surface of the upper weight portion 12 is changed by changing the meshing angle between the lower weight portion 11 and the upper weight portion 12. Can be adjusted.

In this adjustment, the lower surface of the lower weight portion 11 is placed in contact with the ground inclined by an angle θ, and the upper weight portion 12 is rotated with respect to the upper surface of the lower weight portion 11 by a predetermined angle in the circumferential direction. And place it. In the combination of the lower weight portion 11 and the upper weight portion 12, the meshing tooth 25 of the lower weight portion 11 is fitted with the meshing tooth 25 of the upper weight portion 12, and the convex portion of the mating projection 24 is formed in the central space of the meshing tooth 21. To insert. Therefore, the central axes of the lower weight portion 11 and the upper weight portion 12 coincide with each other, and the meshing teeth 21 and 25 mesh with each other, so that the upper weight portion 12 is fixed from the lower weight portion 11 without sliding in the horizontal direction. .

When the upper weight portion 12 is rotated and combined with the lower weight portion 11 in the circumferential direction, the upper surface of the lower weight portion 11 has an inclination shown by A in FIG. The lower surface is inclined as shown by B in FIG. Since the inclination angles of both are formed so as to be inclined with respect to the vertical lines of the lower weight portion 11 and the upper weight portion 12, the upper weight portion 12 has its central axis with respect to the lower weight portion 11 depending on the inclination angle of both. Will be tilted. If the angle at which the central axis of the upper weight portion 12 is inclined with respect to the central axis of the lower weight portion 11 is adjusted to be θ, the upper weight portion 12 is inclined in the opposite direction so as to cancel the inclination angle θ of the ground. And is placed on the lower weight section 11. Thus, if the upper weight portion 12 is inclined at the angle θ in the direction opposite to the angle θ at which the ground is inclined, the upper weight portion 12
Is canceled out, the central axis of the upper weight portion 12 coincides with the vertical line, and the upper surface of the upper weight portion 12 becomes horizontal.

Thus, even if the lower weight portion 11 is inclined by the ground, the central axis of the upper weight portion 12 is vertical and the central axis of the holding hole 13 is also adjusted in the vertical direction. Therefore, when the fixed leg 17 is inserted into the holding hole 13, the fixed leg 17 and the frame body 15 are held in the vertical direction. In this way, if the upper weight portion 12 of each weight 1 is placed on the upper surface of the lower weight portion 11 while being adjusted by rotating in the circumferential direction, each upper weight portion 1
The central axes of 2 can be corrected vertically, and the fixed legs 17 inserted into the holding holes 13 of the upper weight portions 12 can be maintained vertically.

Then, one fence body 2 is held by two weights 1 arranged at equal intervals, and two frame bodies 15 and 15 are held on the left and right sides of each one weight 1. In the holding of the two frame bodies 15 by the holding holes 13, the fixing legs 17, 17 of the left and right frame bodies 15 and 15 are simultaneously inserted into one holding hole 13, and as shown by the chain line in FIG. The fixed leg 17 of one frame body 15 is inserted into the semicircular portion 30, and the fixed leg 17 of the other frame body 15 is inserted into the semicircular portion 31. When the fixed legs 17 and 17 are thus inserted into the single holding hole 13, the side surfaces of the frame members 15 and 15 located on both sides come into close contact with each other, and in this close contact state, as shown in FIG. The connection caps 3 are fitted from above the frames 15 and 15, and the tops of the frames 15 and 15 on both sides are connected to the connection caps 3.
Fix with. By sequentially performing such work,
A fence body 2 having a plane portion is provided by holding a single fence body 2 between a plurality of weights 1 arranged at equal intervals.
You can assemble a temporary fence to enclose the surroundings by continuing.

When assembling a temporary fence with the weight 1, the fence body 2 and the connecting cap 3, the fence body 2 is not linearly continuous depending on the construction site, but the fence body 2 and the side surface of the fence body 2 are in the middle. It may be necessary to bend and set up. In this case, the side surfaces of the frame bodies 15 and 15 must be angled, but for such an installation, one frame body 15
The fixed leg 17 of is inserted into the space of the spare circular portion 34, and the fixed leg 17 of the other frame 15 is inserted into the space of the spare circular portion 35.
The two fixing legs 17 and 17 inserted into the one holding hole 13 have a semicircular portion 3 with a distance between the central axes of the preliminary circular portions 34 and 35.
Since the distance is greater than the distance between the center axes of 0 and 31, the fixed legs 17 and 17 are held apart. For this reason, there is a space between the side surfaces of the frame bodies 15 and 15, and there is an allowance for each of the frame bodies 15 and 15 to freely rotate in the horizontal direction about the spare circular portions 34 and 35. Occur. After that, the frame bodies 15, 15 on both sides can be rotated relative to each other around the fixed legs 17, 17 and bent and held at the required relative angle.

Next, another embodiment of the present invention will be described with reference to FIGS.
0, FIG. 11, and FIG. In this embodiment, the structure of the above-described first embodiment is simplified and the meshing teeth 21, 25 and the like are omitted, but the same operation can be performed functionally. 9 is a side view of a weight of another embodiment, FIG. 10 is a side cross-sectional view of the same weight, and FIG. 11 is an explanatory view showing the structure of the lower surface of the upper weight portion and the upper surface of the lower weight portion. 12 is a plan view showing a state in which the fixed legs 17 of the fence body 15 are inserted into and combined with the holding holes 43 of the upper weight portion.

A holding hole 43 is formed in the center of the upper surface of the upper weight portion 42.

FIG. 9 is a side view of the lower weight portion 41 and the upper weight portion 42 constituting the weight 40.
The lower weight portion 41 and the upper weight portion 42 are circular around each other, and the lower weight portion 41 and the upper weight portion 4 are
It has a columnar shape that is integrated by stacking 2 vertically. While the lower surface of the lower weight portion 41 forms a plane perpendicular to the vertical line, the lower weight portion 4
The upper surface of 1 is formed with a plane having an angle slightly inclined with respect to the vertical line. Further, while the upper surface of the upper weight portion 42 forms a plane perpendicular to the vertical line, the lower surface thereof forms a plane inclined at a slight angle with respect to the vertical line. The inclination angle of the upper surface of the lower weight portion 41 and the inclination angle of the upper surface of the upper weight portion 42 are matched with each other, and when they are vertically contacted with each other, the peripheral shape becomes a columnar shape. Therefore, the lower surface of the lower weight portion 41 and the upper surface of the lower weight portion 42 are parallel to each other, and the upper surface of the lower weight portion 41 and the lower surface of the upper weight portion 42 are inclined with respect to the vertical line. Since the lower weight portion 41 and the upper weight portion 42 can be rotated in the circumferential direction, the lower weight portion 4 will be described later.
It is possible to adjust the circumferential angle in which 1 and the upper weight portion 42 are combined.

FIG. 10 is a sectional view showing the internal structure of the lower weight portion 41 and the upper weight portion 42 which constitute the weight 40 described above. A countersunk seat hole 44 is formed in the center of the lower surface of the lower weight portion 41, and a screw hole 45 is opened at the center of the seat hole 44 so as to penetrate vertically. The upper surface of the lower weight portion 41 is flat, the upper surface thereof is inclined with respect to the lower surface of the lower weight portion 41, and is inclined as indicated by C in FIG.

A holding hole 43 is formed in the center of the upper surface of the upper weight portion 42 so as to extend downward.
The bottom of 3 is a flat surface, and a countersunk hole 46 is formed in the center of this bottom. A screw hole 47 is opened in the center of the seat hole 46 so as to penetrate vertically. The lower surface of the upper weight portion 42 is flat and inclined as shown by D in FIG.

The above-mentioned screw hole 45 is located at the central axis of the lower weight portion 41, and the screw hole 47 is located in the upper weight portion 4.
In order to assemble the weight 40, the lower surface of the upper weight portion 42 is stacked on the upper surface of the lower weight portion 41 so that the screw holes 45 and 47 are aligned with each other.
Thereafter, the head of the bolt 48 is inserted into the screw hole 45 from the lower surface of the lower weight portion 41, and the bolt 48 is inserted until it reaches the upper end of the screw hole 47. Then, the nut 49 is inserted from the holding hole 43, and the nut 49 is screwed into the bolt 48 at the position of the seat hole 46. The number of nuts 49 to be screwed in is two, and the lower nut 49 is stopped at a position where it does not come into contact with the lower surface of the seat hole 46, and the upper nut 49 is screwed into the bolt 48 as a double nut. Fix it. For this reason, the bolt 48 is fitted with both screw holes 45, 47.

And the upper weight part 42 are connected, but both lower weight parts 4
1 and the upper weight portion 42 are not tightly tightened, but have play so that they can be freely rotated in the circumferential direction around the bolt 48.

Next, a case where the weight 40 of this embodiment is used to support the fence body 2 on the ground inclined by the angle θ will be described with reference to FIG.

As shown in FIG. 9, the weight 40 in which the upper and lower surfaces of the lower weight portion 41 and the upper weight portion 42 remain parallel to each other
If the lower surface of the lower weight portion 41 is placed in contact with the ground inclined at the angle θ, the upper surface of the upper weight portion 42 is inclined at the angle θ. In this way, when the ground surface on which the lower surface of the lower weight portion 41 is placed is inclined, the upper weight portion 42 is not attached to the lower weight portion 41.
Can be rotated in the circumferential direction to change the contact angle, and the horizontalness of the upper surface of the upper weight portion 42 can be adjusted.

In this adjustment, the lower surface of the lower weight portion 41 is placed in contact with the ground inclined by the angle θ, and the upper weight portion 42 is rotated by a predetermined angle in the circumferential direction with respect to the upper surface of the lower weight portion 41. Let This upper weight part 4
In the rotation of 2, the bolt 48 is not in contact with the screw holes 45 and 47, and the bolt 48 and the nut 49 are not tightening the seat holes 44 and 46. Therefore, the upper weight portion 42 is lower than the lower weight portion 41. Can rotate freely with respect to. If the upper weight portion 42 is rotated by a predetermined angle and the lower surface of the upper weight portion 42 is placed in contact with the upper surface of the lower weight portion 41 as it is, both are held at the rotated position by friction. .

When the upper weight portion 42 is rotated in the circumferential direction with respect to the lower weight portion 41, the inclination angle of the surface in contact with the upper weight portion 41 is in the direction of canceling the inclination angle θ of the ground, and the upper weight portion 42 is The central axis of the lower weight portion 41 is inclined. The angle at which the central axis of the upper weight portion 42 is inclined with respect to the central axis of the lower weight portion 41 is θ.
If adjusted so that, the upper weight portion 42 is inclined in the opposite direction so as to cancel the inclination angle θ of the ground. In this way, if the upper weight portion 42 is inclined at the angle θ in the direction opposite to the angle θ at which the ground is inclined, the inclination of the upper weight portion 42 is canceled and the central axis of the upper weight portion 42 is aligned with the vertical line. However, the upper surface of the upper weight portion 42 is horizontal.

Thus, even if the lower weight portion 41 is inclined by the ground, the central axis of the upper weight portion 42 is vertical and the central axis of the holding hole 43 is also adjusted in the vertical direction. Therefore, when the fixed leg 17 is inserted into the holding hole 43, the fixed leg 17 and the frame body 15 are held vertically. In this way, if the upper weight portion 42 of each weight 40 is placed on the upper surface of the lower weight portion 41 while being adjusted by rotating in the circumferential direction, the central axis of each upper weight portion 42 is corrected vertically. Therefore, the fixed legs 17 inserted into the holding holes 43 of the upper weight portions 42 can be maintained vertically. Then, one fence body 2 is held by two weights 40 arranged at equal intervals, and two frame bodies 15 are provided on both left and right sides of each one weight 40.
And hold 15. By performing such work in sequence, a single fence body 2 is held between a plurality of weights 40 arranged at equal intervals, and the fence body 2 having a flat surface portion is continuous to form a temporary fence surrounding the surroundings. Can be assembled.

Next, still another embodiment of the present invention will be described with reference to FIGS. In this embodiment, FIG. 13 is an exploded perspective view of the weight structure, and FIG. 14 is a side sectional view of the weight in an assembled state.

In another embodiment, the holding weight portion 60
Is a cast product or a concrete product which has been used conventionally, and is heavy, and has a cylindrical outer shape. A holding hole 61 having a cross-sectional shape similar to the holding hole 13 described above is bored in the center of the upper surface, and the upper and lower surfaces of the holding weight portion 60 are formed so as to be parallel to each other. Next, there are an intermediate base 62 that adheres to the lower surface of the holding weight portion 60 and a lower base 63 that adheres to the lower surface of the intermediate base 62.
Each have a disk shape, and both are made of a non-slip material such as rubber or synthetic resin. Further, graduations are printed at equal intervals on the outer circumferences of the intermediate base 62 and the lower base 63, and a number is written on each graduation. This is for confirming the relative position when the intermediate base 62 is rotated with respect to the lower base 63.

Next, FIG. 14 is a sectional view showing a state in which the holding weight portions 60, the intermediate base 62, and the lower base 63 shown in FIG. 13 are vertically combined. As described above, a holding hole 61 for inserting the fixed leg 17 is bored in the center of the upper surface of the holding weight portion 60.
A drain hole 64 for letting rain water escape is formed at the center of the bottom of the through hole. A recessed seat hole 65 is formed in the center of the upper surface of the intermediate base 62, and a threaded hole 66 is opened in the center of the seat hole 65. A recessed seat hole 67 is formed at the center of the lower surface of the lower base 63, and a screw hole 68 is formed at the center of the seat hole 67.

After the intermediate base 62 and the lower base 63 are brought into close contact with each other from above and below, the bolt 69 is inserted from the lower side of the screw hole 68, and the head of the bolt 69 is projected from the seat hole 65. Then, the nut 70 is inserted through the seat hole 65, and the nut 70 is screwed into the bolt 69. There are two nuts 70 for screwing in.
Stop at a position where it does not come in contact with the lower surface of No. 5, and screw the upper nut 70 into the bolt 69 as a double nut,
Fix 0 and 70 to the bolt 69. Therefore, the bolt 6
9 is inserted into both screw holes 65 and 67, and the intermediate base 62 and the lower base 63 are connected by this bolt 69.
Both are not tightened tightly, but bolt 6
It has play so that it can freely rotate in the circumferential direction at 9.

The lower surface of the intermediate base 62 is formed so as to be inclined by an angle α with respect to the upper surface thereof.
The upper surface of 3 is formed to be inclined by an angle α with respect to the plane. Therefore, in the state shown in FIG. 14, since the intermediate base 62 and the lower base 63 are combined at the angle α, the upper surface of the intermediate base 62 and the lower surface of the lower base 63 are parallel to each other.

In the third embodiment, when the lower base 63 is placed on the horizontal ground, the combination shown in FIG. 14 is used. In this case, the lower surface of the lower base 63 and the upper surface of the holding weight portion 60 are used. Are parallel to each other, the central axis of the holding hole 61 of the holding weight portion 60 is vertical.

However, when the lower surface of the lower base 63 is installed on the ground inclined as shown by the inclination angle θ as shown in FIG. 15 in the combination shown in FIG. 14, the upper surface of the holding weight portion 60 is inclined at the angle θ. As a result, the fixed leg 17 inserted into the holding hole 61 is tilted. In such a case, the intermediate base 62 is rotated with respect to the lower base 63 in the circumferential direction for adjustment. Since the bolt 69 connecting the intermediate base 62 and the lower base 63 is loosely fitted in the screw holes 66 and 68, the intermediate base 62 can be freely rotated with respect to the lower base 63. Then, when the intermediate base 62 is rotated, the upper surface of the lower base 63 forms an angle α with the lower surface thereof.
Since the lower surface of the intermediate base 62 is inclined by an angle α with respect to the upper surface of the intermediate base 62, the intermediate base 62 makes a swivel similar to a rasping motion.
It will be inclined from the lower surface of No. 3.

The intermediate base 62 is rotated until the angle at which the intermediate base 62 is inclined with respect to the lower base 63 is θ, and the intermediate base 62 is held on the upper surface of the lower base 63 at that angular position. As described above, when the relative angle between the intermediate base 62 and the lower base 63 becomes θ, the inclination of the central axis of the intermediate base 62 is canceled by inclining in the direction opposite to the inclination angle θ of the ground, and FIG.
Oriented vertically as shown at 5. Further, since the holding weight portion 60 is placed on the upper surface of the intermediate base 62, the central axis of the intermediate base 62 is similarly oriented vertically.

In this way, if the center axis of the holding weight portion 60 becomes vertical by rotating the intermediate base 62 by a predetermined angle in the circumferential direction and adjusting the axis, the axis of the holding hole 61 is maintained in the vertical direction, Fixed leg 17 inserted in the holding hole 61
Is held vertically. Since the intermediate base 62 and the lower base 63 are made of rubber or synthetic resin, if the intermediate base 62 and the two are brought into close contact with each other after the intermediate base 62 is rotated, the intermediate base 62 slides down from the lower base 63 or moves in the circumferential direction. It does not rotate.
