Description

[Detailed explanation of the idea] This invention relates to a pinning device with a mechanism that allows the film to be freely adjusted.

It is possible to install and mount various devices and devices on a vehicle or other moving body, stop the vehicle after moving it to the desired location, and then set up or deploy the main parts of the device in order to operate the device. be exposed.

When moving the vehicle or the like, it is necessary to fix the equipment or the like so that it does not move at the mounting position.

This is because if equipment, etc. moves inside the vehicle due to shaking or vibration while the vehicle is running, there is a risk that the vehicle will become unstable, and this may cause problems such as damage to the equipment, etc. be.

For example, as shown in FIG.
This is necessary in a structure in which the support 5 to which the observation device 4 is attached around the axis 3 of the column can be erected in the 4' and 5' positions during operation.

When running or moving the prop 5 with the prop 5 tilted on the stand, the prop 5 is fixed to the stand with a locking device 6 to prevent the prop 5 from moving due to shaking, vibration, impact, or the like.

The above-mentioned fastening device 6 can be fixed using conventional methods such as hanging a strap on the support 5, fixing it on a stand using screws, fasteners, etc. using fasteners provided on both sides, or fixing the fastening on the support 5 using screws, fasteners, etc. When standing up, there is a method of removing the hook by remote control using a special electromagnet or electric motor.

The former method is not only cumbersome as it requires manual operation each time the locking device is fixed or released, but is also dangerous because it may involve standing up while working at a high place.

The latter method requires complex mechanisms and electrical circuits as well as many components.

This invention provides a safe and reliable stopping device that does not require any of the complicated configurations and operations described above.

An embodiment of the locking device 6 according to the present invention will be described in detail below with reference to the drawings.

FIG. 2 is a cross-sectional view of the stopper device 6 viewed from a normal position, and FIG. 3 is a cross-sectional view taken along the line BB in FIG. 2.

Note that FIG. 2 corresponds to the AA cross-sectional view of FIG. 3.

A groove-shaped receiver 61 and a guide fitting 62 are fixed to the upper part of the receiver 61 at a predetermined position on the vehicle base 1 by tightening bolts 63.

Before tightening, a cylindrical sliding locking member 64 having a square hole and an octagonal outer surface is attached to the inner cylinder.

This locking member 64 is fitted into the groove of the receiver 61, and its movement in the left and right direction is restricted, and the square hole is fitted with the guide fitting 62, so that it is fixed to a predetermined size, that is, sliding lock, on the guide fitting 62. Material 6
It is configured to be slidable in the front-back direction by the amount of the clearance in the front-back direction defined by the square hole on the inner surface of No. 4 and the guide fitting 62.

On the other hand, a hook-shaped locking metal fitting 65 is fastened to the support column 5 at a position facing the receiver 61 and the like on the stand by tightening with a bolt 63.

The sliding locking member 64 has a smooth first sliding surface and a second sliding surface E that are inclined parallel to each other at the front end of one end and the rear end of the lower end, and the base fitting 65 has a smooth sliding surface E that is inclined parallel to each other. and a second smooth surface EK, which are parallel to each other, have a first inclined surface D' and a second inclined surface E', and have an open space therebetween containing the above-mentioned locking material 64. .

Therefore, when the column 5 starts to move in the direction of standing up the column 5 in the engaged state, that is, in the direction of the arrow F, the stopper 6
The first and second inclined surfaces E/ of 5 move upwardly along the first and second sliding surfaces E, respectively.

However, since the first and second sliding surfaces E are parallel inclined surfaces, the sliding locking member 64 does not fit the receiving metal 61 and the guide metal fitting 6.
2, it begins to slide forward, that is, in the direction of arrow C, with a component force determined by the second sliding surface E and the second inclined box E' that come into contact with each other.

Such movement causes the sliding locking member 64 to move in the direction of arrow C at the housing where the first sliding surface E and the second inclined surface E' are separated from each other.

As described above, after the engaged state is released, the support column 5 can be freely erected.

Next, when the column 5 is tilted, if the sliding locking member 64 of the locking device 6 maintains the state at the time of detachment of the first casing that moved forward as described above, the bare locking metal When the first inclined surface D' of the sliding locking member 65 comes into contact with the sliding surface of the sliding locking member 64 near their respective tips, the sliding locking member 64 is moved in the direction opposite to the arrow C and the second slope The clear surface E and the second inclined surface y fit together,
Finally, the holding fitting 65 holds the sliding connecting member 64 on its inner surface and is engaged in the state shown in the figure.

However, if the sliding locking member 64 had moved backward in the same position as the position shown in FIG. A downwardly inclined third smooth surface H provided at the rear of the upper end of the movable locking member 64 has a clean contact surface inclined parallel to the third smooth surface H provided at the lower end of the connecting fitting 65. G makes contact and the sliding locking member 64 is moved in the direction of arrow C.

Along with this movement, the hook-shaped peak @M formed between the contact surface G and the second smooth surface E of the metal fitting 650 descends beyond the rear end vertical surface N of the locking member, and the above-mentioned locking occurs. As in the operation, the second edge iE and the second inclined surface E' fit together, and the sliding locking member 64 and the plain metal fitting 65 are brought into a locked state.

The present invention further includes a viscous damping body in front of the sliding connecting member 64.
For example, a dashpot 66 is provided.

A movable shaft of the dashpot 66 is connected to a sliding locking member 64, and the outside is fixed to the vehicle 1.

In the figure, the dashpot 66 is shown schematically.

Based on the above configuration, the dashpot 66 has a relatively gentle sliding connection in one direction when the pillar 5 is raised or tilted as described above. However, if a sudden movement is applied, a braking force acts and prevents the movement of the sliding locking member 64.

In other words, if vibrations, shocks, etc. are applied while the vehicle 10 is running in a direction that lifts the support column upward F, the sliding locking member 64 is attached to the locking device 6 at the second inclined surface E' of the base fitting 65.
Although a force is generated to move the strut 5 in the direction of arrow C, the braking action by the dashpot 66 absorbs the force, so that the strut 5 does not separate from the vehicle 1.

Next, when a vibration force is applied to push the column 5 downward, the upper part of the sliding locking member 64 is pressed against the inner surface of the mating metal fitting 65, stabilizing the engaged state as shown in the figure. Keep it.

When there is almost no vibration, the weight of the support column 5 and the device 40 is applied to the locking device 6, so that the locking device 6 is in a stable engagement state as described above.

Furthermore, another actual case of the present invention is shown in a side sectional view in Fig. 4,
This will be explained below with reference to the drawings.

A T-shaped bar 67 is provided in parallel in front of the sliding locking member 64.
as a rotatable fulcrum and a sliding locking member 64 at each end.
, a dashpot 66, and a tension spring 68 are coupled to a linkage mechanism.

The spring 68 is connected to the support 5 together with the base fitting 65 and the sliding locking member 64.
After separation, the sliding locking member 64 is moved back in the direction of the arrow, returning the sliding locking member 64 to the vicinity of the engaged position.

When the support column 5 is tilted, the sliding locking member 64 and the bare fitting 65 abut on the contact surface G and the third smooth surface H, and the top of the second smooth surface E and the contact surface G @ The sliding locking member 64 is pushed back to M, and the first sliding surface and the first inclined surface D', as well as the second clear surface E and the second inclined surface E', begin to fit together. In this case, since the spring 68 pushes the spring 68 in the direction 1, there is no need to lengthen the inclined surface D' of the fastener 65.

It is also convenient because it adds to the braking force of the dashpot 66 for braking the movement of the sliding locking member 64 in the C direction due to vibration.

The link movement mechanism includes a sliding locking member 64 and a dashpot 6.
Not only can the positional relationship of the levers 6 be set arbitrarily, but also the force applied to each lever can be determined by appropriately selecting the length of the lever.

As explained in detail above, the locking device according to the present invention is
The membrane can be moved freely by using the force of the erecting device, and moreover, it will not come off due to vibrations, shocks, etc. when the membrane is in its original state.

In addition, since no special configuration or operation is required, it can be used as a fixing part of a device mounted on a moving body, etc., with excellent effects.

11 The grooved receiver 61 described in the detailed explanation of the present invention
, the guide fitting 62 and the sliding locking member 64 are not limited in shape or mutual relationship as in this example, and the same applies to the means for returning the base material 64.

In addition, to deal with the lateral forces received from the shaking of the vehicle, etc., it is necessary to provide appropriate guides to prevent the supports, etc. from being moved laterally, and to prevent the props from being moved laterally. It is easily possible to configure them in combination.

In addition, by installing locking devices in parallel or using a plurality of locking devices, it is possible to prevent the device from being exposed to vibrations or other forces from various directions.

It can also be applied to enable a device or the like to be removed from a vibration table or the like while it is stopped, and to be attached so that it does not come off during vibration.
