Description

BACKGROUND OF THE INVENTION

Often times it is necessary to mount an object to surface, while facilitating a position of the object to be modified as necessary. Accordingly, a number of connectors have been developed so that the object can be mounted to the surface and then the angle and direction in which the object is position can be dynamically modified. As an example, in a Radio Frequency Identification (RFID) system, antennas are mounted to a portal. The direction in which each antenna is mounted affects the transmission and reception of RFID signals. Accordingly, connectors are used to allow the direction of the antenna to be changed without reattaching the connector each time.

However, existing connectors are expensive to manufacture and often include several moving parts. Accordingly, there exists a need for improvements to quick mount connectors.

DETAILED DESCRIPTION OF THE EMBODIMENTS

For convenience, like numerals in the description refer to like structures in the drawings. Referring to FIGS. 1a and 1b, an isometric view of a connector is illustrated generally as reference numeral 100. The connector 100 comprises a base member 102, a coupling member 104, an object mount 106, a locking assembly 108 and a pin 110.

The base member 102 is configured to be attached to a structure or surface upon which the entire connector 100 is to be mounted. The object mount 106 is configured to be attached to an object, such as an antenna for example. The coupling member 104 is configured to be rotatably coupled to the base member 102. Specifically, the coupling member 104 is configured to rotate about a first axis of rotation 112, aligned with its central axis. Accordingly, the coupling member 104 can rotate in the direction indicated by arrow A. The object mount 106 is configured to be rotatably coupled to coupling member 106. Specifically, the object mount 106 is configured rotate about a second axis of rotation 114. The second axis of rotation 114 is located at a point of connection between the coupling member 104 and the object mount 106 and is normal to the first axis of rotation 112. Accordingly, the object mount 106 can rotate in the direction indicated by arrow B.

Referring now to FIGS. 2a to 2c, the base member 102 is illustrated in greater detail. The base member 102 comprises support plate 201, a cylinder 203 and attachment passages 212. In this embodiment, the support plate 201 is ring shaped and includes a plurality of openings (not shown). The cylinder 203 includes a first cylindrical portion 202, a second cylindrical portion 204, an opening 206, base teeth 208, and a lip 210. The first cylindrical portion 202 is proximate to the inner circumference of the support plate 201. The second cylindrical portion 204 is distal to the inner circumference of the support plate 201. In this embodiment, the first cylindrical portion 202 has a greater circumference than the second cylindrical portion 204. The base teeth 208 project from the inner surface of the second cylindrical portion 204. The lip 210 is configured to cover the base teeth 208. Thus, the opening 206 of the cylinder 203 is smaller at the second cylindrical portion 204 than at the first cylindrical portion 202. The attachment passages 212 are positioned by the openings in the support plate 201 and are sized to receive screw, bolts or the like to connect the base member 102 to a mounting surface.

Referring now to FIGS. 3a to 3c, the coupling member 104 is illustrated in more detail. The coupling member 104 comprises a cylindrical portion 301, a pair of spaced apart plates 303 and a support block 305.

The cylindrical portion 301 includes coupling teeth 302 and pin holes 306. The coupling teeth 302 are positioned along an edge of the cylindrical portion 301 and project from the outer surface. The pin holes 306 are diametrically opposed and positioned away from the coupling teeth 302. Specifically, the pin holes 306 are positioned at a distance sufficient to accommodate the lip 210 of the base member 102.

The plates 303 are generally rectangular and extend from the cylindrical portion 301 away from the coupling teeth 302. The plates 303 include bolt apertures 310 and protrusions 316. The support block 305 is positioned between the pair of plates and configured to extend along only a portion of the length of the plates 303. Bolt apertures 310 are positioned at opposing bolt positions in the plates 303. In this embodiment, the support block 305 is present at the bolt positions in the plates 303. Accordingly, the bolt apertures 310 extend through the support block 305. Each plate 303 includes at least one of the protrusions 316 near a plate end distal to the coupling teeth 302.

Referring now to FIGS. 4a to 4d, the object mount 106 is illustrated in more detail. The object mount 106 comprises an object mounting plate 402 and a pair of coupling plates 403. Each of the coupling plates 403 includes a mount bolt aperture 406 and recesses 408. The coupling plates 403 are normal to the object mounting plate 402 and positioned on an opposite surface of the object mounting plate 402 to which the object is to be attached. The coupling plates 403 are substantially triangular and attached to the object mounting plate 402 at their base. Further, the coupling plates 403 stand proud of the object mounting plate 402 and are substantially parallel to each other in a spaced apart relationship. The recesses 408 are sized to receive the protrusions 316 of the coupling member 104. Further, the recesses 408 are aligned in an arcuate manner such that they are furthest from the object mounting plate 402 at the edges of the coupling plates 403.

Referring to FIG. 5, the locking assembly 108 is shown in greater detail. In this embodiment, the locking assembly 108 includes a bolt 502 affixed, at one end, to a knob 504. The bolt 502 is configured to be inserted through the bolt apertures 310 and the mount bolt apertures 406, and fastened in place using a nut 506. The locking assembly 108 can be loosened and tightened by rotation of the knob 504.

Referring to FIG. 6, the pin 110 is shown in greater detail. In this embodiment, the pin 110 comprises a round end 508 end an angled end 510. The rounded end 508 assists in gripping the pin 110 for removal or insertion in the pin holes 306. The angled end 510 is configured to inhibit accident removal from the pin holes 306.

To assemble the connector 100, the coupling member 104 is coupled with the base member 102 by inserting the coupling member 104 through the opening 206 of the cylinder 203 until the coupling teeth 302 engage the base teeth 208. Complete passage of the coupling member 104 through the opening 206 is blocked when the coupling teeth 302 engage the lip 210. The coupling member 104 can be locked in place by inserting the pin 110 through the pin holes 306. This restricts the coupling member 104 from being withdrawn through the opening 106 and holds the lip 210 between the pin 110 and the coupling teeth 302.

The object mount 106 is coupled with the coupling member 104 by aligning the mount bolt apertures 406 on the object mount 106 with the bolt apertures 310 on the coupling member 104 and inserting the locking assembly 108 there through. The protrusion 316 is positioned to engage a corresponding one of the recesses 408 on the object mount 106. As the locking assembly 108 is tightened, a greater pressure is applied between the plates 303 of the coupling member 104 and the coupling plates 403 of the object mount 106. Accordingly, the protrusions 316 more robustly engage the corresponding recesses 408 and restrict rotation of the object mount 106 about the second axis of rotation 114. Base member 102 can be attached to a surface and an object can be attached to the object mount 106.

The positioning of the object can be adjusted by rotating the coupling member 104 about the first axis of rotation 112 and rotating the object mount 106 about the second axis of rotation 114. In order to rotate the coupling member 104, the pin 110 is removed from the pin holes 306. The coupling member 104 can be moved so that the coupling teeth 302 are positioned within the first cylindrical section 202 of the base member 102 and, thereby, disengaged from the base teeth 208. This allows the coupling member 104 to be rotated about the first axis of rotation 112. Once the desired position is reached, the coupling member 104 can be moved so that the coupling teeth 302 are positioned within the second cylindrical section 204 of the base member 102 and, thereby, re-engaged with the base teeth 208. The coupling member 104 is locked in position by replacing the pin 110 into the pin holes 306. As will be appreciated by a skilled person, the resolution at which coupling member 104 can be rotated depends, at least in part on the size of the base teeth 208 and the coupling teeth 302.

In order to rotate the object mount 106, the locking assembly 108 is loosened by rotating the knob 504. The pressure applied between the plates 303 of coupling member 104 and the coupling plates 403 of the object mount 106 is lessened. This allows the object mount 106 to be rotated about the second axis of rotation 114. Once the desired position is reached, the locking assembly 108 is tightened and the protrusions 316 once again engages corresponding recesses 408, thereby restricting rotation of the object mount 106 about the second axis of rotation 114. As will be appreciated by a skilled person, the resolution at which object mount 106 can be rotated depends, at least in part on the size of the protrusion 316 and the recesses 408, as well as the number of recesses 408.

The configuration of the connector 100 permits for adjustment of orientation of the object mount 106 such that an object, such as an antenna, connected to the object mounting plate 402 can quickly and easily be positioned in a variety of directions at a number of different angles. The parts of the connector 100 are relatively inexpensive and easily manufactured.

Although the embodiment described above uses the pin 110 to lock the coupling member 104 is place, the pin 110 may be optional. For example, if the base member 102 is connected to a surface so that it is positioned above the object mount 106, gravity may be sufficient to maintain engagement between the base teeth 208 and the coupling teeth 302.

A person of skill in the art will appreciate that while bolts are described as connecting the base member 102 to a mounting surface, any suitable connection means may be used. Furthermore, greater or fewer attachment passages 212 may be used. In addition, the attachment passages 212 may be excluded and an adhesive may be used to connect the base member 102 to a mounting surface.

Although embodiments have been described above with reference to the figures, those of skill in the art will appreciate that variations and modifications may be made without departing from the scope thereof as defined by the appended claims.
