1. Field of the Invention
The present invention generally relates to television antennas, and more specifically relates to supports for holding such television antennas in an upright position.
2. Description of the Prior Art
There are a number of planar indoor television antennas which receive digitally formatted high definition broadcast signals. Two such antennas, having a hard body, plastic planar housing, are disclosed in U.S. Pat. No. 6,429,828, which issued to Prapan Paul Tinaphong, et al., and is entitled “VHF/UHF Self-Tuning Planar Antenna System”, and U.S. Pat. No. 8,269,672, which also issued to Prapan Paul Tinaphong, et al., and is entitled “Omni-Directional, Multi-Polarity Low-Profile Planar Antenna”, the disclosures of which are incorporated herein by reference. There are also planar television antennas currently on the market which are formed with an ultra-thin, flexible housing. An example of such a flexible planar antenna is disclosed in U.S. Patent Application Publication No. 2015/0054705, which issued as U.S. Pat. No. 9,281,571, naming as inventors Prapan Paul Tinaphong, et al., and entitled “Ultra-Thin, Flexible, Broadband Low Profile Planar Wire Antenna”, the disclosure of which is incorporated herein by reference.
Although the aforementioned planar high definition television antennas will work to receive signals when disposed in a horizontal position, it is usually recommended that such antennas be disposed in an upright, vertical position, preferably near a window or at a high elevation, for best reception of television broadcast signals. Some of these planar television antennas have openings or recesses on their housings for mounting the antennas on a wall or to a window in a vertical position.
However, it may be desired by the owner of such a planar antenna not to mount the antenna permanently to a wall or window, and yet be able to secure the antenna in an upright, vertical position without it tipping over.
It is an object of the present invention to provide an antenna stand for mounting a planar television antenna in an upright, vertical position.
It is another object of the present invention to provide an antenna stand for holding flexible planar antennas in an upright position and provide support for such flexible antennas so that they do not bend while being held in such an upright position.
It is still another object of the present invention to provide an antenna stand for planar television antennas, which stand is adjustable so that it may receive and hold in an upright, vertical position planar antennas of differing dimensions.
It is a further object of the present invention to provide an antenna stand for flexible and hard case planar television antennas which avoids the need for having to mount such antennas permanently or semi-permanently on a window or wall.
In accordance with one form of the present invention, a stand for receiving and holding a planar television antenna includes a base, a support frame mounted on the base, and an extendable antenna holding arm which is adjustably mounted on the frame. The frame preferably includes a pair of lower clips that project outwardly from a surface thereof on which the bottom edge of a planar antenna may rest. The extendable arm includes an upper clip projecting from a surface thereof which may be used to engage the opposite upper edge of the planar antenna.
Accordingly, a planar television antenna, such as those described previously, may be mounted on the antenna stand of the present invention and disposed between the lower clips of the frame and the upper clip of the extendable arm. The extendable arm may be adjusted on the frame so that the position of the upper clip relative to the lower clips may be adjusted such that the antenna stand may accommodate and support planar antennas having housings of different dimensions.
In accordance with another form of the present invention, a stand for receiving and holding a planar television antenna includes a base and a laterally arcuate support frame mounted on the base. The frame preferably includes a pair of clips that project outwardly from a surface thereof on which the bottom edge of a planar antenna may rest.
Accordingly, a planar television antenna, especially one which has a non-rigid, flexible housing such as disclosed in the aforementioned U.S. Patent Application Publication No. 2015/0054705 (now, U.S. Pat. No. 9,281,571), may be mounted on the antenna stand of the present invention and disposed on the clips of the frame. The curvature of the arcuate shape of the antenna support frame imparts a slight curvature or bend transversely (i.e., horizontally) to the flexible planar antenna mounted on the stand, and this slight curvature or bend will maintain the antenna in an upright position and prevent the antenna from folding over on itself. The antenna stand adds rigidity to a flexible planar antenna in the vertical direction, and the flexible planar antenna will remain in an upright position even though it only rests at its lower edge on the clips of the stand and without the need for the antenna stand to support its upper edge.
These and other objects, features and advantages of the present invention will be apparent from the following detailed description of illustrative embodiments thereof, which is to be read in connection with the accompanying drawings.
Reference should be initially had to
More specifically, the base 4 is a plate-like member which is preferably rectangular in shape with rounded corners to appear almost oval, although the base 4 can take on any shape, including round or oblong, as long as it provides adequate stability to the antenna stand 2 and an antenna 10 mounted thereon. The base 4 has a top side 12 and an opposite bottom side 14. Preferably, there are two groups 16 of openings formed through the thickness of the base 4, each group 16 consisting of four spaced apart slots 18. As will be described in greater detail, these slots 18 receive prongs 20 extending downwardly from the support frame 6 so that the support frame 6 may be mounted on and secured to the base 4.
On the bottom side 14 of the base 4 there are preferably four partition walls 22, 24 extending perpendicularly outwardly therefrom. Two of the walls 22 are preferably U-shaped and the other two walls 24 are preferably round in shape. The partition walls 22, 24 define an interior area 26 for receiving rubber feet (not shown) therewithin, the rubber feet being provided to minimize or prevent the base 4 and antenna stand 2 from slipping on or marring a surface of furniture or a window sill on which the antenna stand 2 is placed. The rubber feet may be secured to the surface of the bottom side 14 of the base 4 by using an adhesive or the like.
The support frame 6 stands upright on and perpendicular to the base 4. The support frame 6 is also generally a planar member preferably having a U-shape, with two opposite lateral, vertical legs 28 which are separated from and situated parallel to each other, and a transverse or horizontal cross member 30 joined to the upper sections of the lateral, vertical legs 28. The support frame 6 includes a front side 32 and an opposite rear side 34. The legs 28 are preferably spaced apart from each other to provide a space therebetween to accommodate a feed point housing found on some antennas, such as housing 40 disclosed in the aforementioned U.S. Patent Application Publication No. 2015/0054705 (i.e., U.S. Pat. No. 9,281,571), which housing 40 covers the feed point and the connection of the antenna cable to the antenna.
Each leg 28 of the support frame 6 includes an enlarged footing 36 formed by flaring outwardly in diverging directions the front and rear sides 32, 34 of the legs 28 at the bottom portion thereof. The bottom portion of each vertical leg 28 is formed with this enlarged footing 36 to provide a stable platform for resting on the base 4 of the antenna stand 2 and also to provide suitable surface area for forming thereon four spaced apart resilient prongs 20 on each leg 28. Each prong 20 includes a hooked edge, and the prongs 20 of each leg 28 are dimensioned and spaced apart from each other such that they are in alignment with and may be received by corresponding slots 18 formed in the base 4. The leg prongs 20 of the support frame 6 are inserted into respective slots 18 formed in the base 4 until their hooked edges pass below and engage the surface of the bottom side 14 of the base 4 to lock the support frame 6 in place on the base 4 in an upright, vertical position and perpendicular to the plane in which the base 4 resides.
Each vertical leg 28 of the support frame 6 includes at least one L-shaped lower clip 38 which projects outwardly from the surface of the front side 32 of the support frame 6 on each leg 28, although the lower clips 38 could be formed on the transverse cross member 30 in an alternative embodiment. The distance the L-shaped lower clips 38 project outwardly from the surface of the front side 32 of the support frame 6 is selected based on the overall thicknesses of commercially available planar television antennas such that an edge of the planar antenna 10 may be received by and rest on the L-shaped lower clips 38 of the support frame 6.
The transverse or horizontal cross member 30 of the support frame 6 includes a projection 40 formed on the rear side 34 of the support frame 6, the projection 40 defining a U-shaped channel 42 in transverse cross-section extending therethrough vertically when the support frame 6 is mounted on the base 4 in an upright position. The U-shaped channel 42 is provided to receive the extendable arm 8 of the antenna stand 2.
More specifically, the extendable arm 8 is formed as an elongated member having a U-shape in transverse cross-section which is complementary to that of the channel 42 so that it may be received in the U-shaped channel 42 of the support frame 6. The extendable arm 8 is closely received by the U-shaped channel 42 such that there is a friction fit between the interior walls of the channel projection 40 and the arm 8, but with sufficient force the extendable arm 8 may be raised and lowered vertically with respect to the support frame 6 when received in the U-shaped channel 42 thereof. The extendable arm 8 has a front side 44 and an opposite rear side 46.
The upper free end of the extendable arm 8 includes an L-shaped upper clip 48 which projects outwardly from the surface of the front side 44 thereof and in the same direction that the lower clips 38 project from the surface of the front side 32 of the support frame 6. Thus, because the extendable arm 8 is slidable under force within the U-shaped channel 42 of the support frame 6, the relative distance that the upper clip 48 of the arm 8 is spaced from the lower clips 38 of the support frame 6 is adjustable to accommodate the width or height of most commercially available planar television antennas. Also, the distance the L-shaped upper clip 48 projects from the surface of the front side 44 of the extendable arm 8 is selected, like the lower clips 38, based on the thicknesses of commercially available planar television antennas so that the upper or opposite edge of the planar television antenna may be received by and rest in the upper clip 48 of the extendable arm 8.
The antenna stand 2 of the present invention will support planar antennas 10 that include either a hard case enclosure or a flexible housing in an upright, vertical position and, for flexible antennas, without the antenna bending or bowing, as the vertical legs 28 and horizontal cross member 30 of the support frame 6 and the extendable arm 8 together provide sufficient support over the width or length of the planar antenna 10. Thus, the antenna stand 2 of the present invention may be placed on furniture or on a window sill, for example, and will hold the planar television antenna 10 in an upright position for best reception of high definition broadcast television signals.

More specifically, the base 104 is a plate-like member which is preferably rectangular in shape with rounded corners to appear almost oval, although the base 104 can take on any shape, including round or oblong, as long as it provides adequate stability to the antenna stand 102 and an antenna 10 mounted thereon. The base 104 has a top side 112 and an opposite bottom side 114. Preferably, there are two groups 116 of openings formed through the thickness of the base 104, each group 116 consisting of three spaced apart keyhole-shaped slots 118, the center slot 118a being large than the two outer slots 118b. As will be described in greater detail, these three keyhole-shaped slots 118 receive locking pins 120 extending downwardly from the support frame 106 so that the support frame 106 may be mounted on and secured to the base 104. Each of the keyhole-shaped slots 118 preferably includes an enlarged diameter portion 105 and a reduced diameter portion 103 in communication with the enlarged diameter portion 105 and being relatively smaller than the enlarged portion 105. Preferably, as shown in
There is also a cable clip 140 mounted on the top side 112 of the base 104. The cable clip 140 preferably includes two pairs of different sized and spaced apart resilient prongs to hold between each respective pair a coaxial cable of different diameter.
On the bottom side 114 of the base 104 there are preferably four partition walls 122, 124 extending perpendicularly outwardly therefrom. Two of the walls 122 are preferably U-shaped and the other two walls 124 are preferably round in shape. The partition walls 122, 124 define an interior area 126 for receiving rubber feet (not shown) therewithin, the rubber feet being provided to minimize or prevent the base 104 and antenna stand 102 from slipping on or marring a surface of furniture or a window sill on which the antenna stand 102 is placed. The rubber feet may be secured to the surface of the bottom side 114 of the base 104 by using an adhesive or the like.
The support frame 106 stands upright on and perpendicular to the base 104. The support frame 106 is also generally a U-shaped member, with two opposite lateral, vertical legs 128 which are separated from and situated parallel to each other, and a transverse or horizontal cross member 130 joined to the upper sections of the lateral, vertical legs 128. The support frame 106 includes a front side 132 and an opposite rear side 134. The support frame 106 is also laterally arcuate in shape, that is, exhibiting a relatively small transverse curvature to appear either convex or concave when viewed from the front thereof. As will be explained in greater detail, the small curvature of the frame 106 of the antenna stand 102 will help hold a planar antenna, especially one which has a flexible housing, in an upright position when the antenna is mounted on the stand 102.
Each leg 128 of the support frame 106 includes an enlarged footing 136 formed by flaring outwardly in diverging directions the front and rear sides 132, 134 of the legs 128 at the bottom portion thereof The bottom portion of each vertical leg 128 is formed with this enlarged footing 136 to provide a stable platform for resting on the base 104 of the antenna stand 102 and also to provide suitable surface area for forming thereon the three spaced apart locking pins 120, mentioned previously, on each leg 128.
As also described previously, each locking pin 120 includes a shank 121 extending from the bottom portion of the vertical leg 128 and a head portion 123. The locking pins 120 of each leg 128 are dimensioned and spaced apart from each other such that they are in alignment with and may be received by corresponding keyhole-shaped slots 118 formed in the base 104. The locking pins 120 of the support frame 106 are inserted into respective keyhole-shaped slots 118 formed in the base 104 through the enlarged diameter portions 105 thereof until the head portions 123 of the locking pins 120 pass below the surface of the bottom side 114 of the base 104. The legs 128 are then moved horizontally on the base 104 so that the shanks 121 of the locking pins 120 slide into the reduced diameter portions 103 of the keyhole-shaped slots 118. Accordingly, in this position, the head portions 123 of the locking pins 120, which have a diameter relatively larger than that of the reduced diameter portions 103 of the slots 118, are vertically secured below the surface of the bottom side 114 of the base 104 to lock the support frame 106 in place on the base 104 in an upright, vertical position and perpendicular to the plane in which the base 104 resides.
Each vertical leg 128 of the support frame 106 includes at least one L-shaped clip 138 which projects outwardly from the surface of the front side 132 of the support frame 106 on each leg 128, although the clips 138 could be formed on the transverse cross member 130 in an alternative embodiment. The distance the L-shaped clips 138 project outwardly from the surface of the front side 132 of the support frame 106 is selected based on the overall thicknesses of commercially available planar television antennas such that an edge of the planar antenna may be received by and rest on the L-shaped clips 138 of the support frame 106.
By providing the support frame 106 of the antenna stand 102 with a small transverse curvature, any planar antenna 10 having a flexible housing or covering mounted on the stand will take on the same transverse curvature. In other words, and as illustrated in
To utilize the antenna stand 102 formed in accordance with the second embodiment of the present invention, the lower edge of the planar television antenna 10 is received by and rests on the clips 138 formed on the legs 128 of the support frame 106. Thus, the planar television antenna 10 is held in place by the clips 138 and supported on the antenna stand 102 in an upright, vertical position. Furthermore, the clips 138 may be resilient and inwardly biased towards the support frame 106. The resiliency of the clips 138 provides additional support to the antenna 10. When the antenna stand 102 is used to support a flexible planar antenna 10, the curvature of the frame 106 shapes the antenna 10 and limits the ability of the antenna to collapse by providing support thereto.
The antenna stand 102 formed in accordance with the second embodiment of the present invention will support planar antennas 10 that include either a hard case enclosure or a flexible housing in an upright, vertical position and, for flexible antennas, without the antenna bending or bowing, as the vertical legs 128 and horizontal cross member 130 of the support frame 106 provide sufficient support over the width or length of the planar antenna 10. For planar antennas 10 with a non-flexible housing, the clips 138 just need to be made such that they project out from the surface of the front side 132 of the support frame 106 a sufficient distance to compensate for the lateral curvature of the frame 106. Thus, the antenna stand 102 of the present invention may be placed on furniture or on a window sill, for example, and will hold the planar television antenna 10 in an upright position for best reception of high definition broadcast television signals.
Although illustrative embodiments of the present invention have been described herein with reference to the accompanying drawing, it is to be understood that the invention is not limited to those precise embodiments, and that various other changes and modifications may be effected therein by one skilled in the art without departing from the scope or spirit of the invention.
