Abstract

PROBLEM TO BE SOLVED: To ensure easiness, mobility, handleability and safety during moving in the case where a speaker is on board a vehicle. SOLUTION: A sucker 3 is assembled to a mounting plate 2 on which a speaker 1 is placed through an adjustable hinge 12 to be integrally formed. A whole integrally formed is placed on a roof of a vehicle 5 and is retained and fixed by the sucker 3.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001] The present invention is mounted on a vehicle roof or the like, and a loudspeaker is stably mounted on the roof so that it can be moved or advertised. Since the present invention is premised on improving mobility and ease of handling, the pedestal itself with the loudspeaker attached,
It can be easily attached to and detached from the vehicle roof and has a compact structure.

Conventionally, there is no pedestal of this type, and a self-adsorption type rubber sucker utilizing a restoring force of rubber, which is fixed by a loudspeaker mounting bracket called a roof carrier bracket 9 assembled on a vehicle, or the like. It is reinforced with ropes etc. because it is used only as an auxiliary and has low holding power. The weak point is that it takes a long time to disassemble and disassemble, and also requires work tools. In addition, the vehicle is often damaged by metal fittings during disassembly and disassembly.
The roof carrier fitting 9 to be mounted also had to be properly used depending on the size and structure of the vehicle. Also, the rubber sucker type has a serious problem that if the restoring force of the rubber is lost, the degree of vacuum is reduced and the fixing cannot be maintained.

The present invention has solved this problem. The pedestal is composed of a mechanism of a suction cup 3 for adsorbing to the roof of the vehicle 5 at a high vacuum and a mounting plate 2 for mounting the loudspeaker 1.

[0004] In this way, it does not matter if the vehicle 5 to be mounted has a flat or greatly curved roof. For mounting, a mounting plate 2 on which a loudspeaker 1 is mounted is placed on a roof, and a detachable lever 6 of a suction cup 3 attached to a universal hinge 12 with a spring.
When this occurs, the suction surface of the rubber sheet 7 and the roof of the vehicle 5 can be instantaneously held and fixed by suctioning the suction surface between the rubber sheet 7 and the roof of the vehicle 5 with a high vacuum by pulling up the suction rod 8. In this method, a pulling force of about 20 to 80 kg is obtained. . When the degree of vacuum is low, the vacuum pressure gauge 10, the vacuum pressure switch, or the suction position detector 13
You can also check with. For example, even if the roof of the vehicle is a perfectly flat or unbalanced roof, the spring-loaded hinges 12 are attached to the suction cups, so that even if the distance between the mounting plate 2 and the roof varies.

As shown in FIG. 5, the rubber surface of the suction cup can freely contact and adsorb on the roof uniformly. Should the suction come off, the hinge 12 with spring will jump up,

FIG. 6 shows the state shown in FIG. It is also possible to notify that the vacuum pressure gauge 10 and the suction position detector 13 have been operated and have jumped up. With this device, any vehicle or structure can be handled, and installation can be completed in a very short time. Conventional mounting methods include a self-adsorption type auxiliary method using a rubber sucker having extremely weak suction force and a method using a roof carrier fitting 9, but these methods are cumbersome and difficult to disassemble and disassemble the loudspeaker 1 to the vehicle 5. Need to purchase the roof carrier metal fittings 9 for each vehicle 5 and have a high possibility of damaging the vehicle 5 during work. Even when dismantled, the parts are large and the number of points is large, so management is troublesome. In this regard, compared to the conventional device, the present device is compact and does not need to be disassembled at all, and can be stored as one. Therefore, the loudspeaker 1 is extremely superior in terms of management and mounting work as compared with the conventional method.
Is an auxiliary device. Of course, it is also effective for the purpose of mounting equipment other than the loudspeaker 1.

Claims (3)

[Claims] A pedestal having a function of easily attaching and detaching a loudspeaker mounted on a vehicle with a suction cup of a high vacuum suction principle having an attachment / detachment mechanism. 2. A pedestal having a function of jumping up the suction cup when the suction cup changes from a suction state of the vehicle to a desorption state due to a vacuum leak. 3. A pedestal having a vacuum pressure gauge, a vacuum pressure switch, a suction position detector and the like attached to the suction cup so that the suction status can be checked at a glance and a pedestal having an alarm function.
