1. Field of the Invention
This invention relates to ball joint mounts that can hold wireless customer-premises equipment or customer-provided equipment (CPE) terminals, antenna or wireless device in place.
2. Description of Related Art
Communication systems such as wireless customer-premises equipment or customer-provided equipment (CPE) terminals, antenna or wireless devices need to be mounted and properly positioned in order to send and receive signals in an efficient manner. Some prior art solutions require the user to know the probable best position azimuth/elevation angles to a station with high precision prior making a fine adjustment due to a limited range of the fine adjustment.
Some prior art solutions require one to use tools and make several steps (e.g. tighten multiple fasteners) in order to lock the antenna or equipment in the proper position. When such antenna or radio equipment is being installed, some prior art solutions require one to do several operations/procedures in order to mount the antenna to the fixed structures and then adjust its position, often requiring assembly in multiple parts and using tools.
Accordingly, it has been determined by the present disclosure that there is a need for ball joint mounts that overcome, alleviate, and/or mitigate one or more of the aforementioned and other deleterious effects of prior art mounts.
An improved antenna ball joint mount comprising a hollow socket mechanically coupled to a spherical member with a locking part. The hollow socket and the spherical member are fully detachable to simplify the installation of an antenna. A user is able to set a position of the antenna to any point on a spherical sector surface within a range of motion allowed by a shape of joint components and rotate the antenna around own axis to adjust a polarization plane and then lock the mount in a predetermined position.
The improved antenna ball joint mount comprises a hollow socket mechanically coupled to a spherical member with a locking part. A typical ball joint consists of a bearing stud and socket enclosed in a casing, the difficulty with that construction, is that the bearing stud retains freedom to move within the socket, but it cannot readily be held in place, the present invention solves that problem by threading the locking part with male threads and the hollow socket with female threads, enabling the user to screw the locking part onto the hollow socket holding the spherical member in place.
Turning to these components in more detail, the locking part can come in form of a nut typically, but not limited to, with inner thread with a hole in center, to accommodate the spherical member with wide range of allowed movement relative to the hollow socket part. The nut can be equipped with surface easing the grip necessary when the improved antenna ball joint is operated by hand such as ribs or other grating. The hollow socket and spherical member can be made with a coarse finish or other way to increase the friction, so when the locking part is tightened even by hand, it can create a strong friction forces sufficient to fix the position of the spherical member.
The spherical member is mechanically coupled to an antenna which is communicatively coupled to a receiver, transceiver, or wireless device in a manner that is well known in the art. The socket can be mechanically coupled to a surface when the user so desires. This ball joint provides many advantages over the prior art including being able to move the antenna in the horizontal, vertical and spin/rotation directions.
There are three stages of mounting. First the user attaches the antenna into target place by mounting one part of the ball joint onto a structure first. Next, the user attaches antenna by screwing the locking part lightly, allowing the user to find proper direction where signal level is greatest by movement of the antenna with a controlled level of friction. In some embodiments this can be done by observing signal level e.g. using a target device's light emitting diodes (LEDs), utilizing earphones, a voltmeter or observing the signal level using a laptop and then pinpointing the proper direction were signal level is greatest by movement with controlled level of friction in the ball joint where the level of friction adjustable is by screwing the locking part. Third to fix the ball joint again by tightening the locking part so that friction in the ball joint is high enough to keep the antenna in a proper direction, under normal loads such as wind, snow, birds and so on approaching the antenna.
A ball joint mount is provided that includes a ball joint, a mounting member, and a mounted member. The ball joint has a spherical member, a socket member, and a locking member. The spherical member and the locking member form a first portion of the ball joint. The socket member forms a second portion of the ball joint. One of the first and second portions of the ball joint depend from the mounting member and the other of the first and second portions of the ball joint depend from the mounted member. The socket member has a first thread and the locking member has a second thread. The first and second threadably engage one another so as to secure the spherical member between the socket and locking members to prevent relative movement between mounting and mounted members.
In some embodiments, the first thread is an internally facing female thread and the second thread is an externally facing male thread. Here, the locking member can include an outer rim and an internal rim and the socket member includes an outer rim and an inner rim. The outer rim of the locking member can have a larger inner diameter than an outer diameter of at least the outer rim of the socket member. The inner rim of the locking member can include the externally facing male second thread thereon and the outer rim of the socket member can include the internally facing female first thread thereon.
A method of mounting an antenna or wireless device is provided. The method includes the steps of securing the antenna or wireless device and a first portion of a ball joint to one another; securing a mounting device with a second portion of the ball joint to one another; securing the mounting device in a desired location; connecting first and second portions of the ball joint to one another by loosely forming a threaded connection between first and second threads; adjusting a position of the antenna or wireless device to a desired position; and tightening the locking member so as to lock the ball joint in the desired position. Here, one of the first and second portions of the ball joint includes a spherical member and a locking member as a unitary subassembly and the other of the first and second portions of the ball joint includes a socket member. The socket member has a first thread and the locking member has a second thread. The first and second threads threadably engage one another so as to secure the spherical member between the socket and locking members to prevent relative movement between mounting and mounted members.
The above-described and other features and advantages of the present disclosure will be appreciated and understood by those skilled in the art from the following detailed description, drawings, and appended claims.
Referring to the drawings and in particular to
Mounting member 12 is illustrated by way of example in the embodiments of
Mounted member 16 is illustrated by way of example in the embodiments of
In each embodiment, ball joint 14 includes a spherical member 20, a socket member 22, and a locking member 24.
In the embodiments of
However in the embodiment of
Accordingly, it should be recognized that mount 10 can be configured having ball joint 14 in any desired orientation with respect to the mounting and mounted members 12, 16, respectively.
Socket member 22 has a first thread 30, while locking member 24 has a second thread 32. First and second threads 30, 32 are configured to threadably engage one another so as to secure the spherical member 20 between socket and locking members 22, 24. In this position, ball joint 14 prevents relative movement between mounting and mounted members 12, 16.
In the illustrated embodiments of
Additionally and in the illustrated embodiments of
Turning now to simultaneous reference to
Regardless of the orientation of ball joint 14, the use of mount 10 includes essentially the same assembly steps. First, mounting member 12 is secured to the desired structure or location with one of the portions of ball joint 14 secured thereto. Then, mounted member 16 is secured to mounting member 12 by threadably connecting the remaining portion of ball joint 14. The threaded connection of the first and second portions 34, 36 of ball joint 14 can be loosely formed at first—which connects the mounting and mounted members 12, 16 to one another but allows adjustment of the position of the mounted member 16 in three axes. Once mounted member 16 is in the desired position about the three axes, locking member 24 can be tightened to lock ball joint 14 in the desired position.
Advantageously, first portion 34 of ball joint 14, regardless whether it is present on mounting member 12 as in the embodiments of
As can be seen in the embodiments of
Referring to
Mount 110 includes a mounting member 112, a ball joint 114, and a mounted member 116.
Mounting member 112 is again illustrated as a bracket, while mounted member 116 is illustrated as second bracket that can be secured to any desired (CPE) terminal, antenna or wireless device such as, but not limited to, any type of active, passive, or combined active-passive device.
Ball joint 114 again includes a spherical member 120, a socket member 122, and a locking member 124. Similar to the embodiments of
Spherical member 120 is secured to mounting member 112 by a bolt 140 and a nut 142. Preferably, locking member 124 is secured between mounting and spherical members 112, 120 so as to be rotatable for threaded connection with socket member 122 in the manner described in more detail below.
In some embodiments, ball joint 114 includes a cover 144, which covers a head of bolt 140. Cover 144 can be formed of a rigid material or of an elastomeric material. When formed of an elastomeric material, cover 144 can protrude from an outer surface of spherical member 120 so that it is compressed by the threaded connection of ball joint 114 and can provide an increased coefficient of friction between spherical and socket members 120, 122.
In some embodiments, ball joint 114 includes a bearing 146 positioned between spherical and locking members 120, 124. Bearing 146 can assist rotation of locking member 124 with respect to spherical member 120 during the tightening of the locking member. Bearing 146 can include one or more slots 148 defined therein, which generally extend parallel to the central axis of the ball joint. When ball joint 114 is in use, slots 148 allow bearing 146 to compress or deform under the action of the spherical, socket, and locking members 120, 122, and 124—which can assist in distributing the compressive forces across a greater surface area of the spherical and socket members. Preferably, bearing 146 is formed of a material having sufficient resiliency to return to a normal, undeformed state when ball joint 114 is loosened.
Without wishing to be bound by any particular theory, bearing 146 is believed to provide enhanced fine tune adjustment when locking member 124 is partially tightened. For example, it has been determined that proper directional adjustment of mounted member 116 requires smooth movement of ball joint 114 in a region of between where the ball joint is completely fixed in one location and where it is completely loose with the mounted member not remaining in a particular location. It has been determined by the present disclosure that the addition of bearing 146 to ball joint 116 enhances or increases the smooth movement in this state of partially secured. Simply stated, it is believed that bearing 146 allows fine positional movement of spherical and socket members 120, 122 with respect to one another when locking member 124 has been partially tightened.
Socket member 122 has a first thread 130, while locking member 124 has a second thread 132. First and second threads 130, 132 are configured to threadably engage one another so as to secure the spherical member 120 between socket and locking members 122, 124. In this position, ball joint 114 prevents relative movement between mounting and mounted members 112, 116.
Here, first thread 130 is shown as an internally facing female thread and second thread 132 is shown as an externally facing male thread.
More specifically and with reference to
Outer rim 150 of locking member 124 enshrouds socket member 122—namely forms the portion of locking member 124 has a larger inner diameter than the outer diameter of at least the outer rim 154 of socket member 122. Inner rim 152 of locking member 124 includes the externally facing male second thread 132 thereon.
Outer rim 154 of socket member 122 includes the internally facing female first thread 130 thereon. Inner rim 156 of socket member 122 forms a part of the wall of the socket in which cylindrical member 120 is received.
Of course, it is contemplated by the present disclosure for first thread 130 to be a female thread and/or internally facing, and second thread 132 to be a male thread and/or externally facing.
Locking member 124 is received over and retained on spherical member 120 such that the combination of the spherical and locking members 120, 124 forms a first portion 134 of ball joint 114. When present, cover 144 and bearing 146 are similarly part of first portion 134 of ball joint 114. Socket member 122 forms a second portion 136 of ball joint 114.
Again, the use of mount 110 includes essentially the same assembly steps as those discussed above. First, mounting member 112 is secured to the desired structure or location with one of the portions of ball joint 114 secured thereto. Then, mounted member 116 is secured to mounting member 112 by threadably connecting the remaining portion of ball joint 114.
Advantageously, first portion 134 of ball joint 114, regardless whether it is present on mounting member 112 or present on the mounted member 116 is preassembled and includes both spherical and locking members 120, 124 as a unitary subassembly. Accordingly, ball joint 114 permits one operator to easily assemble, adjust, and lock mounted member 116 in the desired position with respect to mounting member 112. The threaded connection of the first and second portions 134, 136 of ball joint 114 can be loosely formed at first—which connects the mounting and mounted members 112, 116 to one another but allows adjustment of the position of the mounted member 116 in three axes. Once mounted member 116 is in the desired position about the three axes, locking member 124 can be tightened to lock ball joint 114 in the desired position.
Referring to
Mount 210 includes a mounting member 212, a ball joint 214, and a mounted member 216. Mounting member 212 is again illustrated as a bracket, while mounted member 216 is illustrated as second bracket that can be secured to any desired (CPE) terminal, antenna or wireless device such as, but not limited to, any type of active, passive, or combined active-passive device.
Ball joint 214 again includes a spherical member 220, a socket member 222, and a locking member 224. Similar to the embodiments of
Spherical member 220 is formed in multiple parts that are secured to mounting member 212 by a bolt 240. Preferably, locking member 224 is secured between mounting and spherical members 212, 220 so as to be rotatable for threaded connection with socket member 222 in the manner described in more detail below.
In some embodiments, ball joint 214 includes a bearing 246 positioned between spherical and locking members 220, 224. As discussed in detail above, bearing 246 can assist rotation of locking member 224 with respect to spherical member 220 during the tightening of the locking member and allows for smooth movement of ball joint 214 in a region of between where the ball joint is completely fixed in one location and where it is completely loose with the mounted member not remaining in a particular location.
Socket member 222 has a first thread 230, while locking member 224 has a second thread 232. First and second threads 230, 232 are configured to threadably engage one another so as to secure the spherical member 220 between socket and locking members 222, 224. In this position, ball joint 214 prevents relative movement between mounting and mounted members 212, 216.
Ball joint 214 is shown having a cover 244, similar to cover 144 discussed above, but cover 224 is positioned in socket member 222 and, not, in spherical member 220. As discussed above, cover 244 can be formed of an elastomeric material that protrudes from an inner surface of socket member 222 so that it is compressed by the threaded connection of ball joint 214 and can provide an increased coefficient of friction between spherical and socket members 220, 222.
While not shown, it is also contemplated by the present disclosure for ball joint 214 to have covers or elastomeric members on both spherical and socket members 220, 222 to increase the friction therebetween.
In this embodiment, first thread 230 is shown as an externally facing male thread and second thread 232 is shown as an internally facing female thread.
More specifically and with reference to
Outer rim 250 of locking member 224 enshrouds socket member 222—namely forms the portion of locking member 224 that has a larger inner diameter than the outer diameter of at least the outer rim 254 of socket member 222. Inner rim 252 of locking member 224 includes the internally facing female second thread 232 thereon.
Outer rim 254 of socket member 222 includes the externally facing male first thread 230 thereon. Inner rim 256 of socket member 222 forms a part of the wall of the socket in which cylindrical member 220 is received.
Of course, it is contemplated by the present disclosure for first thread 230 to be a female thread and/or internally facing, and second thread 232 to be a male thread and/or externally facing.
Locking member 224 is received over and retained on spherical member 220 such that the combination of the spherical and locking members 220, 224 forms a first portion 234 of ball joint 214. When present, bearing 246 is similarly part of first portion 234 of ball joint 214. Socket member 222 and cover 244, when present, form a second portion 236 of ball joint 214.
Again, the use of mount 210 includes essentially the same assembly steps as those discussed above. First, mounting member 212 is secured to the desired structure or location with one of the portions of ball joint 214 secured thereto. Then, mounted member 216 is secured to mounting member 212 by threadably connecting the remaining portion of ball joint 214.
Advantageously, first portion 234 of ball joint 214, regardless whether it is present on mounting member 212 or present on the mounted member 216 is preassembled and includes both spherical and locking members 220, 224 as a unitary subassembly. Accordingly, ball joint 214 permits one operator to easily assemble, adjust, and lock mounted member 216 in the desired position with respect to mounting member 212. The threaded connection of the first and second portions 234, 236 of ball joint 214 can be loosely formed at first—which connects the mounting and mounted members 212, 216 to one another but allows adjustment of the position of the mounted member 216 in three axes. Once mounted member 216 is in the desired position about the three axes, locking member 224 can be tightened to lock ball joint 214 in the desired position.
