Description

[Brief explanation of drawings]

Figures 1 to 6 are continuous diagrams showing the deployment sequence as an example of this invention, with Figure 1 showing the state immediately after the start of deployment, and Figure 2 showing the deployment arm being deployed. Figure 3 is a diagram showing a state where the deployment arm has finished being deployed and the deployment arm and lower arm are being deployed, Figure 4 is a diagram showing the state in which the arm has been deployed, and Figure 5 is a diagram showing the state in which the deployment arm is deployed. FIG. 6 is a diagram showing a state in which the deployment wire is cut and the entire arm is being deployed, and FIG. 6 is a diagram showing a state in which all deployment has been completed. Figures 7 and 8 are diagrams showing the boom and extension mechanism. Figure 7 is a diagram showing the air bag extension mechanism and boom in the first embodiment of this invention, and Figure 8 is a diagram showing the boom and extension mechanism in the first embodiment of this invention. It is a figure which shows the extension mechanism and boom by a motor, a pulley, and a wire in an Example. 9a and 9b are diagrams showing an example of a conventionally considered deployable antenna, FIG. 10 is a detailed diagram of the arm when stored in a conventional example, and
The figure is a detailed view of an arm when deployed in a conventional example. In the figure, 1 is a lower arm, 2 is a deployable arm, 3 is a mesh mirror surface, 4 is a center hub, 5 is a rotating hinge with a spring, 6 is a rotating hinge, 7 is a boom, and 8
10 shows a deployment wire, 9 an air bag, 10 a motor, 11 a wire, and 12 a pulley. Note that the same reference numerals in the figures indicate the same or corresponding parts.

Claims (1)

[Claims for Utility Model Registration] (1) A plurality of lower arms each having a rotating hinge with a spring for deployment at the lower end, which is attached to the upper end of the lower arm with a rotating hinge, and is itself bendable by the plurality of rotating hinges. A deployable arm, a lock mechanism for maintaining the deployed state of the lower arm and the deployable arm, a boom that deploys the lower arm and the deployable arm, and after deployment, a boom that holds the power supply part or the sub-reflector, and an extender of the boom. The air bag, the mesh mirror surface supported by the lower arm and the deployment arm, the holding wires that hold the lower arm and the deployment arm in the stored state, and the deployment of multiple deployment wires connecting the tip of the deployment arm and the tip of the boom begin. A deployable parabolic antenna characterized by comprising a cutting mechanism that cuts the holding wire when the holding wire is opened, and a deploying wire cutting mechanism that cuts the deploying wire after the lower arm and the deploying arm are locked. (2) a plurality of lower arms each having a rotational hinge with a deployment spring at the lower end; a deployment arm that is attached to the upper end of the lower arm with a rotational hinge and can itself be folded by a plurality of rotational hinges; the lower arm; A lock mechanism to maintain the deployed state of the deployable arm, a boom that deploys the lower arm and the deployable arm, and after deployment, a boom that holds the power supply section or sub-reflector, a motor that extends the boom, and a motor that transfers the rotational force of the motor to the boom. a mesh mirror surface supported by the lower arm and the deployable arm; a holding wire that holds the lower arm and the deployable arm in the retracted state; a wire and a pulley that converts the extension force into an extension force; A deployment type characterized by comprising a deployment wire that ties together, a retention wire cutting mechanism that cuts the retention wire at the start of deployment, and a deployment wire cutting mechanism that cuts the deployment wire after the lower arm and deployment arm are locked. parabolic antenna.
