Technical Field
The present disclosure relates to a tilt bracket that includes a first bracket portion, a second bracket portion, and a pivot arrangement connecting the first bracket portion and the second bracket portion such that the first bracket portion and the second bracket portion are pivotable between a fully open position, a fully collapsed position, and an intermediate position.
Background
When mounting a device such as an antenna to a vertically extending structure such as a building or pole, the angle of inclination of the antenna may need to be taken into account. One way to accommodate different tilt angles is to attach one end of the antenna to a vertically extending structure by a pivot joint about which the antenna can rotate, and attach the other end of the antenna to the vertically extending structure by a retractable arm. The angle of tilt of the antenna can be adjusted by manually adjusting (e.g., using a handle) the length of the retractable arm.
Antennas and similar devices are often large and heavy and are often installed in hard-to-reach areas such as high-rise buildings, making both the installation process and subsequent adjustment of the devices difficult. It is therefore desirable to provide a device that simplifies the installation and adjustment of such equipment.
Disclosure of Invention
It is an object of the present invention to provide an improved tilting bracket. The foregoing and other objects are achieved by the features of the independent claims. Other embodiments are apparent from the dependent claims, the description and the drawings.
According to a first aspect, a tilt bracket is provided. The tilt frame includes a first frame portion, a second frame portion, a pivot arrangement, a gear mechanism, and a blocking mechanism. The pivot arrangement connects the first frame portion and the second frame portion such that the first frame portion and the second frame portion can pivot between a fully open position, a fully collapsed position, and an intermediate position. The gear mechanism comprises a first cogwheel connected to the first carrier part and sharing a central axis with the pivot means. The blocking mechanism is pivotable between an engaged position and an unengaged position. The blocking mechanism includes a catch that engages the gear mechanism when in the engaged position. The blocking mechanism allows the gear mechanism to pivot the first and second rack portions toward the fully folded position when the blocking mechanism is in the unengaged position or when the blocking mechanism is in the engaged position. The blocking mechanism prevents the gear mechanism from pivoting the first and second frame portions toward the fully open position when the blocking mechanism is in the engaged position. The blocking mechanism allows the gear mechanism to pivot the first and second frame portions toward the fully open position when the blocking mechanism is in the unengaged position.
A tilting bracket with a gear mechanism which is always movable in the folding direction and locked or movable in the opposite direction allows to arrange the tilting bracket in a fully folded end position and to maintain this condition during mounting, so that the tilting bracket protrudes as little as possible, thereby taking up little space and reducing the risk of damaging the bracket during mounting. Such a gear mechanism also reduces the risk of the tilt bracket accidentally opening, causing the device to fall and possibly hit the installer. In addition, the gear mechanism helps to bear the weight of the device attached to the tilt bracket, especially since the installer does not need to use one hand to support the antenna at the desired angle while using the other hand to secure the tilt bracket in the correct position, thereby reducing the burden on the installer during installation.
In a possible embodiment of the first aspect, the gear mechanism further comprises a second cogwheel connected to the second carrier part, the tilting carrier further comprising a turning mechanism comprising a turning rod connected to the second cogwheel and sharing a central axis with the second cogwheel, the catch engaging with the second cogwheel when in the engaged position, such that the tilting mechanism only needs a small force applied by the installer.
In another possible embodiment of the first aspect, the blocking mechanism is in the engaged position, the catch slides over the top of the cog of the gear mechanism when the first and second housing portions are pivoted towards the fully folded position, and the catch interlocks with the side of the cog of the gear mechanism when the first and second housing portions are pivoted towards the fully open position, such that the tilt housing can be folded together without the installer applying too much force while the tilt housing can be held securely in the open position.
In another possible embodiment of the first aspect, the first and second frame portions each comprise a middle portion and side portions, the side portions being arranged at opposite edges of the middle portion and extending substantially perpendicular to the middle portion, the first frame portion folding into the second frame portion when the first and second frame portions are pivoted towards the fully folded position such that the tilt frame has as small an outer dimension as possible in the fully folded position.
In another possible embodiment of the first aspect, the tilt bracket further comprises a locking mechanism for locking the blocking mechanism in the unengaged position, such that the tilt bracket can be moved from the folded position to the more angularly expanded position without interference from other components.
In another possible embodiment of the first aspect, the locking mechanism extends perpendicular to the sides of the second housing portion and interconnects with the blocking mechanism when the blocking mechanism is in the unengaged position, providing a locking mechanism that is at least partially protected by the second housing portion but is still easily accessible and operable by an installer.
In another possible embodiment of the first aspect, the locking mechanism comprises an asymmetric knob which, when turned, connects with the blocking mechanism and moves the blocking mechanism to the unengaged position, facilitating a simple and reliable locking mechanism.
In another possible embodiment of the first aspect, the blocking mechanism further comprises a first blocking rod connected to the catch and extending parallel to the turning rod, the blocking mechanism being moved from the engaged position to the disengaged position by moving the first blocking rod in a direction towards the gear mechanism, providing a blocking mechanism which is easy for an installer to install and operate.
In a further possible embodiment of the first aspect, the catch extends from an end of the first blocking rod in a direction towards the gear mechanism, and wherein the blocking mechanism is pivotally connected to a side of the second housing part, facilitating a simple and reliable locking mechanism.
In another possible embodiment of the first aspect, the blocking mechanism further comprises a second blocking bar extending parallel to the first blocking bar, and the locking mechanism comprises hook means extending from the first blocking bar and interlocking with the second blocking bar in the unengaged position, so that the tilting bracket is easy to release from the engaged position and is also easy to hold in the unengaged position.
In another possible embodiment of the first aspect, the blocking mechanism comprises a spring loaded plate, which by moving the plate in a direction away from the gear mechanism, the blocking mechanism is moved from the engaged position to the unengaged position, providing an inexpensive but still reliable blocking mechanism.
In another possible embodiment of the first aspect, one edge of the spring loaded plate is connected to the middle of the second bracket part and the catch is arranged at the opposite edge of the spring loaded plate, providing a blocking mechanism that is protected by the bracket parts but still easy for the installer to reach and operate.
In another possible embodiment of the first aspect, the tilting frame comprises two interconnected gear mechanisms, the blocking mechanism comprises two interconnected catches, one catch being arranged at each side of the second frame part, providing a stable and always symmetrically operating tilting frame.
In another possible embodiment of the first aspect, the first cogwheel is integrated with a side of the first bracket part, providing a strong and durable and cost-effective tilting bracket.
In another possible embodiment of the first aspect, the first cogwheel is attached to a side of the first frame part, and by providing the tilt frame with a gear mechanism, the existing gearless tilt frame can be significantly improved.
In another possible embodiment of the first aspect, the turning mechanism further comprises a turning nut arranged outside the side of the second bracket part, and the second cogwheel is arranged inside the side of the second bracket part, so that the tilting bracket is easy to operate by the installer, even remotely.
According to a second aspect, a pivotable antenna structure is provided. The pivotable antenna structure includes an antenna, a pivot bracket, and a tilt bracket according to the above, the tilt bracket and the pivot bracket connected to the antenna, the tilt bracket pivoting the antenna about the pivot bracket as the first and second bracket portions pivot between the fully open position, the fully collapsed position, and the intermediate position. Such an antenna structure is reliable, safe and easy to operate for the installer, since the tilting bracket has a gear mechanism which is always movable in the folding direction and locked or movable in the opposite direction.
In a possible embodiment of the second aspect, the pivot bracket and the tilt bracket are adapted to be connected to a vertically extending structure, the tilt bracket being arranged at a position vertically above the pivot bracket, the tilt angle of the antenna being able to be increased by the weight of the antenna alone.
In another possible embodiment of the second aspect, the antenna is held at a desired angle relative to the vertically extending structure by means of a tilting bracket, allowing for simple and convenient adjustment of the tilt angle of the antenna.
This and other aspects will be apparent from the embodiments described below.
