Description

[Detailed explanation of the invention] This invention is applicable to ambulances, construction vehicles, patrol cars,
This invention relates to a lifting device for a so-called hidden revolving light that is installed in a security vehicle or the like and can be moved up and down reliably and quickly from the inside of the housing to the roof of the vehicle when emergency driving is required, for example.

(Prior Art) Conventionally, regarding lifting devices for concealed revolving lamps, for example, the first conventional example is Utility Model Publication No. 13688 of 1982, the main part of which is shown in Figure 4. The structure is a revolving light in which an opening is provided on the roof surface of the vehicle, a canopy A1 is pivoted to the opening so that it can be opened and closed, a stay A11 having a guide groove is fixed to the back side of the canopy A1, and a revolving light A3 is fixed. Mounting stand A4
By rotating the rotating drive shaft A41 by 90 degrees, the rotating light is rotated up and down from a horizontal state to an upright state on the vehicle roof surface, and the rotating light mounting base A4 and stay A11 are rotated.
The torsion bar A2 is connected to the guide groove A12 in the opening direction of the canopy A1, and the canopy A1 is rotated 180 degrees by the torsion bar A2 in conjunction with the 90 degree rotation of the rotating light mount A4. The structure is such that the amplification is performed to open and close the elevating opening of the rotating light. Further, the fulcrum of the torsion bar A2 is rotatably supported by a fixed fulcrum A22 of the rotating light mount A4, and rotatably and movably supported by a movable fulcrum A23 of the canopy. The center part of the torsion bar A2 is fixed to the bottom surface of the rotating light mount A4, and the left and right ends of the torsion bar A2 are fixed to the back surface of the canopy A1. It was configured to engage with a pair of stays A11.

Next, as a second conventional example, there is Utility Model Publication No. 13689 of 1982, the main part of which is shown in Fig. 5, in which a rotating light mount B4 is rotatably supported on a rotating drive shaft B41 so that it can be rotated up and down. The arm B2 is supported between the stay B11 on the lower surface of the canopy B1, which is pivotably attached to the canopy B1, and the rotating light mount B4, and the rotating light is turned sideways by rotating the rotating light mount B4 by 90 degrees. The rotating lamp is configured to rotate up and down from the state to an upright position on the vehicle roof surface, and the canopy B1 connected to the arm B2 interlocks and amplifies the rotation by 180 degrees in the opposite direction to open and close the lifting opening of the rotating light. It is something to do. Further, the arm B2 has a bending portion B22 that can be freely extended and bent.
The canopy B1 and the revolving light mount B4 are bent appropriately to the outside and inward during lifting and lowering operations, thereby interlocking the canopy B1 and rotating light mount B4.

(Problems to be Solved by the Invention) However, in the above-mentioned conventional type, when the rotary lamp rotates and lowers, it is necessary to move the fulcrum of the connecting member or bend it, so the lifting and lowering movement is not smooth and shocks may occur. Also, it was not possible to prevent fluctuations such as the strength and weakness of the support pressure of the canopy. Therefore,
If an unstable condition occurs during operation, it may cause flapping noise due to the influence of the wind, wear of the sliding parts, changes in the support pressure of the canopy over time, etc., which will generally shorten the life of the rotating light elevating device. This caused a decrease in operational reliability.

(Purpose of the invention) This invention was devised in view of the above problems, and minimizes the impact during lifting and lowering operations, provides stable and reliable lifting performance, and extends the life of the lifting device of rotating lights. It is an attempt to do so.

(Means for solving the problem) For that purpose, the lifting device for the rotating light is
The main internal parts consist of a rotating light mount on which the rotating light is placed, a rotating shaft that drives the rotating light mount, a motor that applies rotational force to the rotating shaft, and a deceleration mechanism. is surrounded by a cabinet, a canopy is provided above it, and the rotating light mounting base is rotated through 90 degrees around a rotating shaft driven by a motor, so that the rotating light appears on the roof of the vehicle, or At the same time, the rotating light mount fixed fulcrum, which rotatably supports the arm connecting the rotating light mount and the canopy, and the canopy fixed fulcrum are linked to rotate 180 degrees.

(Function) With the above-mentioned configuration, the supporting pressing force of the canopy by the arm is strong and constant even when the rotating light is moved up and down, for example. In addition, since there are no sliding parts and no members that cause strong wear, each mechanical component does not deteriorate, and rotating members are provided with high precision, making it easy to maintain the accuracy of connection and rotation by the arm during manufacturing. Can be done.

(Example) This invention will be further explained below with reference to an example shown in FIGS. 1, 2, and 3.

Reference numeral 1 designates the roof of the vehicle, and an opening is provided, and a rotation mechanism is attached to the inner surface of the revolving light of the present invention, and the revolving light that sends out a warning signal is exposed through the opening.

Reference numeral 2 denotes a cabinet having an opening at the top, and houses a revolving light, a motor, deceleration mechanism parts, lifting mechanism parts, etc. inside.

3 is a rotating light that emits a rotating flash to warn the surroundings. The rotating light may also be another warning device such as a flashing light.

Reference numeral 4 designates a revolving light mounting base that lifts and lowers the revolving light, and is composed of a flat plate portion on which the revolving light is placed, and a pair of leg plate portions that are fixed to the swing drive shaft 41 and support the flat plate portion. It has a U-shape.

Reference numeral 5 designates a canopy that covers the upper opening of the housing 2 and is pivotally attached to the roof of the vehicle so as to open and close as the rotating light goes up and down. It lifts and lowers the rotating light 3 and lifting mechanism parts, and has a substantially square plate shape. canopy 5
is pivoted with several hinges, and 52 is a rotation axis. 51 is a flat stay fixed to the inner surface of the canopy 5, and is connected to the rotation drive shaft 41.
In conjunction with the 90° rotation, it rotates 180° in both forward and reverse directions.

Reference numeral 6 denotes an arm for interlocking the canopy 5 and the rotating light mount 4, which is a rod made of a rigid body (not shown), and includes a rotating light mount fixing fulcrum 61,
The rotating lamp fixed fulcrum 62 is connected and interlocked, and each fixed fulcrum is rotatably supported. Further, the distance between the rotating light mounting base fixed fulcrum 61 and the canopy fixed fulcrum 62 is configured to be the same at any point in time when the rotating light is moved up and down.

However, configuring the distance between the rotating light mounting base fixed fulcrum 61 and the canopy fixed fulcrum 62 to be the same at any point in time when the rotating light is raised or lowered requires mechanical design in a limited space. It is difficult because Therefore, in order to obtain the same effect even if other fulcrum positions having substantially the same distance are adopted, in the embodiment, the arm 6 is made of an elastic material and is gently curved. Therefore, even if there is a slight deviation in the position between the fulcrums, the elasticity of the curved part absorbs the deviation, and the same effect as a rigid connecting rod can be obtained. It is easy to adjust the distance between the supporting points.

7 is wrapped around the rotating light mount fixing fulcrum 61 of the arm 6, one end extends onto the lower surface of the rotating light mount 4 to serve as a holding part 71, and the other end goes inward of the curved part of the arm 6. It is a coiled spring with a hook piece provided at the tip so as to apply pressure, thereby forming a pressure part 72. As a result, when the rotating light is stored, the canopy 5 is pressed downward, and when the rotating light is used, the canopy 5 is pressed downward to prevent the canopy from flapping due to vibrations, wind pressure, etc., and to prevent rainwater from flowing into the container 2.
There is no intrusion inside.

Reference numeral 8 denotes a motor that rotates the swing drive shaft 41 via a reduction gear 9 and serves as a swing drive source for raising and lowering the rotating lamp.

Next, the operating mechanism of the elevating device will be explained according to the operating states from the stored state to when the rotating light is used.

First, in the revolving lamp storage state, the revolving lamp 3 is housed in the housing 2 horizontally, and the canopy 5 covers the upper opening of the housing 2. At this time, the rotating light mounting base fixed fulcrum 61 of the arm 6 and the canopy fixed fulcrum 62
The position of the arm 6, whose both ends are pivotally supported, corresponds to the bottom dead center. In addition, a coiled spring 7 is wound around the rotating light mounting base fixed fulcrum 61 of the arm 6.
Since the arm 6 is pressed against the inside of the curved portion, a moment is applied in the counterclockwise direction of the rotating shaft 52 of the canopy in FIG. 1, and the canopy 5 is pressed against the vehicle roof surface.

Next, when transitioning from the retracted state to the lifting operation for use of the rotating light, the motor 8
The rotational force of the motor is transmitted to the turning drive shaft 41 via a reduction gear 9 which is a combination of a plurality of gears.
The rotating light mount 4, which is fixed to and interlocks with the rotation drive shaft 41, has the rotation light 3 mounted on its upper surface, and moves up and down by rotation in synchronization with the rotation of the rotation drive shaft 41. It happens. At this time, the distance between the rotating light mounting base fixed fulcrum 61 of the arm 6 and the canopy fixed fulcrum 62 remains constant or approximately constant until the rotating light reaches the top dead center position where it stands upright on the vehicle roof surface. The two fulcrum positions draw circular loci with different centers, and the rotating light mount fixed fulcrum 61 rotates by 90 degrees, and the canopy fixed fulcrum 62 rotates by 180 degrees.

At the top dead center position, the rotating light stands upright and becomes the operating position for sending out a rotating flash, the canopy 5 rotates 180 degrees around the rotation axis 52, and the canopy fixing fulcrum 62 is rotated by the arm 6 In Figure 1, since a clockwise rotational moment is applied, the canopy 5
is pressed against the roof surface of the vehicle and remains stable even when subjected to external forces such as vibrations.

Although the present invention has been described above in relation to the hidden revolving light, it goes without saying that the usable warning source is not limited to the revolving light.

(Effects) Since the present invention is configured as described above, it eliminates the impact and sliding parts that were problems during lifting and lowering operations, and dramatically increases the life of the lifting and lowering device for rotating lights. In addition, it is possible to perform lifting and lowering operations faster than before, and in addition, since each fulcrum position is provided reliably, variations in the provision of each fulcrum position due to workers, work processes, and usage conditions are eliminated. This has great practical effects, such as eliminating the need for adjustment steps in manufacturing.
