Description of the Preferred Embodiment
An embodiment of a holding apparatus of an antenna apparatus according to the present invention will hereinafter be described with reference to the accompanying drawings.
Initially, the antenna apparatus utilized with a holding apparatus according to the present invention is supposed to be similar to the indoor type television antenna apparatus shown in FIG. 1 of a mounting type which is arranged to be directly mounted on the television receiver 6, as shown in FIG. 2, for example.
As shown in FIG. 1, the antenna apparatus includes a substantially parallelepiped holding member 2 formed of a mold synthetic resin such as an ABS resin, for example, and a pair of rod antennas 1a, 1b having a predetermined length and capable of being expanded and contracted. The pair of rod antennas 1a, 1b are rotatably engaged at respective one ends with the holding member 2 by screws 3 so as to form any angle between the antennas extending in the left and right directions relative to each other.
The holding member 2 has a mounting shaft 4 which is integrally formed with the holding member 2 so as to have a predetermined length and project from the holding member 2 on a side opposite to a side on which the pair of rod antennas 1a, 1b are provided. This mounting shaft 4 is formed into a substantial cylindrical shape having a slit 4a of a predetermined length extending from the free end side of the mounting shaft 4. The mounting shaft 4 also has an expanding portion 4b formed along an outer periphery of the free end portion thereof.
Further, one end of a feeder line 5 is connected to the pair of rod antennas 1a and 1b while the other end of the feeder line 5 is connected to a predetermined portion of a television receiver 6.
If the antenna apparatus is mounted on the television receiver 6 provided with an antenna mounting portion 7, as shown in FIG. 3, similarly to the prior art, the mounting shaft 4 of the antenna apparatus is inserted at its free end into an antenna mounting hole 7a of the antenna mounting portion 7 to be fitted thereto. In this case, the slit 4a provided in the mounting shaft 4 enables the shaft 4 to be inserted and fitted into the mounting hole 7a with ease.
In this case, the expanding portion 4b formed at the free end of the mounting shaft 4 serves as a stopper, which prevents the mounting shaft 4 from being easily disengaged from the antenna mounting hole 7a1a. Further, since the mounting shaft 4 is formed into a cylindrical shape, the antenna apparatus can rotate with ease in the directions shown by the arrow X of FIG. 3. Therefore, the pair of rod antennas 1a, 1b can be adjusted in their orientation and position with ease.
According to one example of the present invention, a holding apparatus as shown in FIGS. 4 through 10 is provided for the above-described antenna apparatus. The holding apparatus includes a top cover 10 and a stand base 20, as shown in FIGS. 4 and 5.
The top cover 10 is formed of a mold part of an ABS resin, for example, and its overall shape is substantially a temple bell shape as shown in FIGS. 4 through 8. The top cover 10 has at its upper side a pair of opening portions 11a and 11b formed so that a pair of rod antennas 1a, 1b of the antenna apparatus can pass therethrough when the antenna apparatus is attached to the holding apparatus. The opening portions 11a, 11b are formed to permit the rod antennas 1a and 1b to tilt within a range of a substantial right angle between the vertical direction and the horizontal direction.
Further, the top cover 10 has formed in its inside a clipping portion for clipping the substantially parallelepiped holding member 2 of the antenna apparatus. The clipping portion has a pair of hook-like resilient tabs 12a and 12b integrally formed on the inside of the top cover 10 and projecting at positions corresponding to the opening portions 11a and 11b. The clipping portion also has position regulating portions 13a, 13b disposed at upper portions of the pair of resilient tabs 12a and 12b.
In this case, the antenna apparatus is supported in such a manner that the position regulating portions 13a, 13b are brought to abut against the upper surface of the substantially parallelepiped holding member 2 of the antenna apparatus while the pair of resilient tabs 12a and 12b abut against the lower surface of the holding member to upwardly urge the same 2.
Further, in this case, since the resilient tabs 12a and 12b are formed at positions corresponding to the opening portions 11a and 11b, a structure of a die for molding the top cover by injection becomes simple.
Further, as shown in FIGS. 7 and 8, the top cover 10 has on its inner side, ribs 14a, 14b, 14c, 14d formed for regulating and guiding both the sides of the holding member 2 of the antenna apparatus. Specifically, the top cover 10 has in its inner side, ribs 14a, 14b integrally formed in a parallel fashion and the ribs 14c, 14d also integrally formed in a parallel fashion in an opposing fashion between the resilient tabs 12a, 12b and the position regulating portions 13a, 13b so that these ribs guide the side surfaces of the holding member 2.
Further, as shown in FIGS. 4, 5, 9 and 10, the stand base 20 is composed of an upper plate 20a of a flared shape formed by molding an ABS resin, for example, and a bottom plate 20b. In this case, the height from the hem portion of the flare shaped portion to the central portion of the upper plate 20a is set larger than the length of the insertion portion of the mounting shaft 4 of the antenna apparatus.
The upper plate 20a has at its central portion a mounting hole 21 of a predetermined depth as shown in FIGS. 4 and 9, so that the mounting shaft 4 of the antenna apparatus is inserted and fitted thereto.
Further the bottom plate 20b may be formed of a metal plate having a predetermined weight such as of iron or the like (so that it prevents the antenna apparatus from being toppled regardless of the angle of the rod antennas 1a, 1b). Then, the bottom plate 20b made of the metal plate is fixed to the upper plate 20a by means of screws 22.
In the present example, as shown in FIGS. 4 and 10, the bottom plate 20b has on the outer periphery of its bottom surface 20b a sheet-shaped cushion material 23 made of foamed neoprene rubber, a felt or the like, for example, attached so as to form a doughnut shape.
The holding apparatus of the antenna apparatus is constructed as described above. Therefore, when the top cover 10 is attached to the antenna apparatus, the pair of rod antennas 1a and 1b are made to stand substantially vertically as shown in FIG. 4 so that the rod antennas 1a and 1b pass through the top cover 10 from the opening side thereof at the opening portions 11a and 11b of the top cover 10, respectively. Thereafter, the antenna apparatus is fitted into the top cover at its holding member 2 so that the pair of resilient tabs 12a, 12b and the position regulating portions 13a, 13b sandwich the antenna apparatus at its holding member 2.
In this case, since the holding member 2 is guided and regulated at its side surfaces by the ribs 14a, 14b, 14c, 14d useful for guiding the holding member 2, the antenna apparatus can be comfortably sandwiched and fitted in the top cover 10.
When the antenna apparatus is mounted on the stand base 20, as shown in FIG. 4, the antenna apparatus is inserted at the mounting shaft 4 from its free end into the central mounting hole 21 of the stand base 20 to be fitted therein. In this case, the slit 4a formed at the free end of the mounting shaft 4 enables the mounting shaft 4 to be inserted and fitted thereinto with ease.
In this case, the expanding portion 4b formed at the free end of the mounting shaft 4 serves as a stopper so that the mounting shaft 4 is prevented from being easily disengaged from the mounting hole 21. Moreover, since the mounting shaft 4 is formed into a cylindrical shape, the antenna apparatus can be rotated relative to the stand base 20 with ease. Therefore, the pair of rod antennas 1a 1b can be adjusted in their orientation and position with ease.
Further, the present embodiment is arranged to provide a gap between the stand base 20 and the top cover 10 when the antenna apparatus is mounted on the stand base 20 and the antenna apparatus is attached with the top cover 10. Thus, the feeder line 5 can be passed through the gap.
At this time, the antenna apparatus can be rotated together with the top cover 10 relative to the stand base 20. Therefore, the pair of rod antennas 1a, 1b can be adjusted in their orientation and position satisfactorily.
According to the present embodiment, as shown in FIGS. 4 and 5, the antenna apparatus can be fitted at its mounting shaft 4 into the stand base 20 at its mounting hole 21 so that the antenna apparatus can be utilized as an on-the-table antenna apparatus.
Moreover, according to the present embodiment, the holding member 2 of the pair of rod antennas 1a, 1b of the antenna apparatus is covered with the top cover 10 so that the antenna apparatus presents an excellent appearance when the antenna apparatus is utilized as the on-the-table antenna apparatus.
Having described a preferred embodiment of the invention with reference to the accompanying drawings, it is to be understood that the invention is not limited to that precise embodiment and that various changes and modifications could be effected therein by one skilled in the art without departing from the spirit or scope of the invention as defined in the appended claims.
