DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0025] Referring now to FIGS. 1, 2 and 3, there is shown one preferred embodiment of a standoff assembly 100 in accordance with the invention installable on a structure to secure a glass panel or a glass railing to the surface of a structure. The standoff provides telescopic mechanism with lock. Telescopic mechanism provides adjustment for the standoff to be flexible in length. The standoff assembly includes cap portion 10 to secure the glass panel.

[0026] The standoff assembly 100 has a retainer 20 secured to a structure by a fastener 50. The retainer 20 is a cylindrical hollow shape structure internally threaded 21 so there is no thread exposed.

[0027] The standoff assembly 100 provides a telescopic mechanism 30 with security feature to hold the telescope 30 in an adjusted position and to prevent unscrewing the telescope 30 once the cap 10 is turned to be removed. The telescope 30 has external threads 31 to secure to the retainer 20. The telescope 30 further has a protruded portion 34 adapted and sized to receive a panel.

[0028] An externally threaded lock 40 is installed inside the telescope 30 for security features. The telescope 30 together with the lock 40 are screwed on the retainer 20. By turning the lock 40 clockwise through its central socket 42, it moves toward the fastener 50 and presses the fastener's head 51. As a result, the telescope 30 is pushed back and locked inside the retainer 20. The external threads of the lock assembly 41 are fully threaded and secured inside the threads of the telescope 31. Lock 40 is turned by a socket tool through its central socket 42 to move inward and presses the head of the fastener 51 and makes the telescope 30 fully secured in an adjusted position. The lock 40 makes the standoff safe once the cap 10 is removed by preventing the telescope 30 to be unscrewed. Once the cap 10 is installed, the lock 40 holds the telescope 30 in an adjusted position.

[0029] According to FIG. 2 an important feature of the present invention resides in the locking mechanism for standoff coming without threads exposed. All threads are cut inside the retainer and outside the telescope.

[0030] In installation, the retainer 20 is secured on the structure and the telescope 30 is threaded into the retainer 20. Then, the lock 40 is turned to push against the head of the fastener 51 to make the telescope 30 tight and secure. The first gasket 12 (As shown in FIG. 3) is slid over the telescope 30, after which a glass panel is mounted on a structure. Then the cap 10 and gasket 13 are inserted and tightened in place to compress the glass panel between the gaskets 12 and 13. The gaskets may be selected from silicone, rubber, a pliable plastic, felt, nylon, wood or other material.

[0031] The glass panel can be aligned in a secure manner. To align the glass panel, the cap 10 is removed first. Then, a socket tool is passed through the central hole of the telescope to access the central socket 42 to release the lock 40. Next, the telescope 30 is turned by a tool to be adjusted. Again, a socket tool is used to turn and engage the lock 40. Finally, the cap 10 is fastened to secure the glass panel.

[0032] There are different types of adjustable standoffs in the market but those with lock come with exposed threads. Adjustable standoffs with hidden threads which are more popular come without locking mechanism which is considered as a safety feature. According to FIGS. 4 and 5 two available standoffs are disclosed. Both designs provide telescoping mechanism to adjust the length of the standoff. One of these standoffs depicted in FIG. 4 is without lock in which retainer 200 is secured by the fastener 500 and the telescope 300 is treaded externally and once is turned it goes in or out into the retainer 200.

[0033] FIG. 5 shows an adjustable standoff with lock 400 in addition to the telescoping mechanism 310. The telescope 310 is threaded 311 on the outside of the retainer 210. Lock 400 goes inside the retainer 210 and it is turned by a key through central socket to push against inside surface of the telescope to be secured. External threads of retainer 311 are exposed when the standoff extends. Exposing threads 311 is a disadvantage for this design.

[0034] As explained above, the first design comes without the lock which is considered as a safety and security feature in glass panels installation. When the cap 110 is installed, it might turn the telescope 300 which causes misadjusting the standoff. When the cap 110 is disassembled it might unscrew the telescope 300 and fall down. The second design is not popular due to exposed threads 311.

[0035] FIGS. 6A, 6B and 6C disclose the installation of the standoff in accordance with the present invention 100. FIG. 6A is a front view of a rectangular glass panel 70. Panels of this type are generally made of strong, thick glass in order that they are strong enough to serve the desired purpose. For example, tempered glass with more than ½ inches thickness is generally used as glass balustrades. Such panels can also be mounted along a mezzanine, a roof, or a stairway.

[0036] FIG. 6B shows a side view of the glass panel 70. It is common to mount these panels by two rows of standoffs 100 including an upper row 71 and a lower row 72. The details of the standoff 100 can be seen more clearly in FIG. 6C in which the standoff 100 is shown in side view. In these figures standoffs 100 are used to secure a glass panel 70 to a support structure 80.

[0037] In installation the retainer 20 of the standoff 100 is fastened to a plurality of fasteners secured on a structure 80. The glass panel 70 further includes bores 150 there through that act as mounting openings and that align with the internally threaded protruded portion 34 of the telescope adapted and sized for insertion of the mounting opening of the panel 70. Each of the retainers 20 is being received by a respective fastener and then the telescope 30 together with the lock 40 are screwed on the retainer 20. The first gasket 12 is attached to the telescope 30. Then, the glass panel 70 is mounted on the protruded portion 34 of the telescope. The second gasket 13 is then slid over the glass panel 70 and secured by the cap 10.

[0038] The described structure will provide a mechanism to easily, quickly and securely mount a glass panel 70 to a support structure 80 and adjusted in place without removing in a secure manner. The adjustable standoff 100 is able to extend or to shorten in length. When the installed glass panel 70 requires an adjustment, the cap 10 is removed. A socket tool is extended to reach the central socket 42 of the lock 40 to be released. While the panel 70 is on the adjustable standoff, the telescope 30 is turned by a socket tool to adjust and tilt the panel 70 consequently. Once adjustment is complete, the lock 40 is turned back again to press the head of the fastener 51 and secure the telescope 30 in adjusted position. Finally, the cap 10 is installed to secure the panel 70 in position.

[0039] As shown in FIGS. 8A, 8B and 8C in installation steps, a T-shape tool is used to turn the lock 40 and telescope 30 according to the present invention. The T-shape tool 60 drives into the central socket 42 of the lock and turns the lock clockwise. The central socket 42 could be in any shape including but not limited to hexagonal, slot or square to be turned by the T-shape tool 60. The T-shape tool 60 is used to turn the telescope 30 through the protruded portion 34 for adjustment.

[0040] The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.

[0041] With respect to the above description, it is to be realized that the optimum relationships for the parts of the invention in regard to size, shape, form, materials, function and manner of operation, assembly and use are deemed readily apparent and obvious to those skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
