Description

[Detailed description of the invention] The present invention relates to the invention of an element folding type television antenna, in which the element can be folded on both sides of the arm, and handling operations for unfolding and folding on both sides of the arm are provided. The purpose of this invention is to provide a new product that is simple and quick with a relatively simple configuration, and in particular allows a multi-stage element for television reception to be automatically deployed with respect to an antenna.

A television antenna in which a plurality of antenna elements are arranged perpendicular to the axial direction of the arm is well known, and since an antenna with elements arranged perpendicular to the arm is quite bulky, it is difficult to store and transport the antenna. Regarding the folding of the above-mentioned elements, proposals have been made, for example, in Japanese Utility Model Publication No. 1504/1983 and Japanese Utility Model Publication No. 6504/1989. However, in such conventional television antennas, it is necessary to fold each element individually or to set them in an orthogonal state by retightening and operating a tightening element provided at the arm attachment part of each element. However, it is clear that the operation is not necessarily easy when the antenna is to be used as an antenna after being transported to a high place such as a rooftop.

The present invention was devised through research to eliminate the disadvantages of the conventional ones as described above, and the antenna element can be unfolded and utilized in a single touch after being transported in a folded state to an antenna installation location such as a rooftop. The element receiving tubes are installed in multiple stages by protruding and inserting into the element setting position of the arm having antenna elements on both sides, respectively, and the element receiving tubes are provided with elastic elements. At the same time, both ends of the elastic material are fixed inside the elements disposed at both ends of each of the above-mentioned element receiving tubes, and a substantially central portion of the elastic material is fixed to the above-mentioned arm together with the element receiving tube. This is a folding element television antenna characterized by the following.

That is, to explain the specific embodiment of the present invention shown in the accompanying drawings, as shown in FIG. The element receiver tubes 2 are inserted and attached by protruding from both sides, and an elastic material 4 is installed inside the element receiver tube 2, and both ends of the elastic material 4 are used to connect the elements disposed at both ends of the element receiver 2. 3, and the stoppers 5, 5 are stoppers that fix the intermediate portions of the element receiving tube 2 and the elastic material 4 as described above together to the arm 1,
At the same time, this stopper 5 also serves as a stopper when the element 3 is inserted into the element receiving tube 2, as shown in FIG. The element receiver tube 2 is made of the elastic material 4.
As shown in FIG. 2, a stopper 5 is connected to the base ends of the elements 3, 3 that have been drawn in to stop them.

That is, in the device according to the present invention as described above, each element 3 is pulled out from both ends of the element receiving tube 2 with the stopper 5 as a boundary, resisting the elasticity of the elastic member 4, and the arm 1
By folding it down along the axis, a folded and stored state is formed symmetrically with respect to the arm 1 as shown in FIG. It is clear that by tying the antenna element to the arm 1 with a string or other means, it can be packed in a compact manner, and therefore it is certainly convenient for packaging and transportation. By releasing this binding state, the elastic material 4
The tensile force automatically aligns the element 3 in the direction of the element receiving tube 2, and then the proximal end of the element 3 is retracted to automatically form the usage state as shown in Fig. 2. When installing this type of TV antenna, which should be installed in a high place such as a rooftop, a large number of elements can be removed by transporting them to the installation site while being folded compactly as described above and releasing the binding state. It is a device that can be used with one touch, and it is true that the binding can be cut and released with scissors, etc., but if a binding device that uses a hook or a snap button is used, the binding can be released in any way. However, it is possible to instantaneously create the above-mentioned state of using a television antenna, and since the structure is extremely simple, consisting of only one elastic material and an element holder, it is highly effective in terms of practical production. It is an idea.
