Suspended glass panel railing system

An ornamental guardrail system that has an improved base assembly, which allows water and debris to escape from the deck surface. The system uses a mounting arrangement that supports the glass panels above the surface of the deck without using full-height posts. This mounting arrangement makes a structural glass railing useful in many types of construction projects that require the surface water to sheet flow under the railing system, or to achieve a certain visual style.

DETAILED DESCRIPTION OF THE INVENTION

Referring now to FIG. 1, my new railing system 1 has a number of sub components. Details of these sub components follow the general description of the system. First, is a top rail 2 is used to secure the tops of glass panels 3. The glass panels are typically ½-inch thick tempered glass. The bottoms of the glass panels fit into an extruded base shoe 4. This view also shows the ends of the rail 2 and shoe 4, which are covered with end caps 2a and 4a respectively.

Unlike prior art designs, there are no full height posts. Moreover, the base shoe does not rest on the finished floor either. Instead, short support posts 5 are attached to the base shoe, as discussed below. These posts are typically grouted into a concrete slab 100 that forms the base floor of the building in which the system is used. Of course if concrete is not used, the posts are secured using techniques common to that particular art.

FIG. 2 shows a partially exploded view of the system. Here, the components are shown in a little more detail. The top rail 2 has an interior cross-section designed to accommodate splicing of rail (discussed below) and a notch 10 designed to receive a length of rigid PVC 11 (polyvinylchloride) plastic used as a protector for the top of the sheet glass 3. The glass sheet 3 is fitted into a slot 12 in the base shoe 4. Note that a flexible rubber protector 13 is placed in the slot 12 to protect the bottom of the infill panel. A bolt 14 is fitted into the base shoe before the glass and rubber are inserted. The bolt secures the base shoe to the post 5. The posts are spaced at regular intervals to give support for the rail system. Note that in the preferred embodiment, the posts are fixed into the slab 100 using a 10,000 p.s.i. grout 15.

FIG. 3 shows a side view of a typical length of panel. In the preferred embodiment, the posts 5 are set at an interval determined by project-specific criteria. The posts raise the base shoe above the finished floor level to allow for drainage and to prevent damming of water or other debris within the area bounded by the railing. Note that FIG. 3 shows a typical spacing of a ½ inch gap 16 between the glass panels 3 and that there are no full height posts in the run.

FIG. 4 shows an exploded end view of a typical assembly. This view shows the top rail 2 with the end cap 2a, the glass panel 3, the base shoe 4, the post 5, the grout 15, the floor surface 100, and the PVC and rubber protectors 11 and 13.

FIG. 5 is an exploded detail of the post and base shoe assembly. In this view details of the post 5 and base shoe 4 are shown. The post 5 is an aluminum extrusion in the preferred embodiment. The post 5 has an internal structure 5a that is formed as part of the extrusion. The internal structure gives the post strength as well as providing a channel for the bolt 14 to keep the bolt centered in the post. The post 5 has a base washer 5b as shown. Note that this view also shows the securing nut 14a that secures the bolt 14 in place.

FIG. 6 is a detail view of the assembled post and base shoe assembly. Here, the glass panel 3 is shown in place along with the base protector 13. Note that after the glass is installed in the base shoe 4 it is sealed in place with 10,000 p.s.i. grout or other suitable adhesive. This figure also shows the bolt 14, Note that in the preferred embodiment, this bolt is a ½ inch (12 mm) diameter T-slot stainless steel bolt (available from the McMaster-Carr Company, as part no. 90321A740) or equivalent. The head of the bolt 14 has a tee head that fits into the T slot formed at the bottom of the base shoe. When the nut 14a is tightened, the bolt secures the base shoe to the post securely.

FIG. 7 is a perspective detail showing the technique used for splicing straight sections of base shoe. Here, two sections of base shoe 4 and 4′ are shown in alignment. Two pins 18 are used for each splice. The pins are secured in the holes 19 formed in the base shoe as shown. In the preferred embodiment, the pins are 316 alloy stainless steel dowel pins 0.250 in (6 mm) diameter by 1 inch (25 mm) long, the pins are secured in one length of base shoe, a second length of base shoe is aligned with the pins and the two lengths are pushed together until the pins are seated and the shoe sections are flush.

FIG. 8 is a cross-section of the post. FIG. 8a is a top view of the post showing the shape and arrangement of the center extrusion.

FIG. 9 shows a cross-section of the base shoe and post assembly as fully assembled and installed in a finish floor. In this view, the glass panel 3 is shown in the base shoe held by grout. Note that the glass panel is typically installed after the posts have been installed on the floor. The bolt is shown in position in the base shoe. The base shoe is shown sitting on top of the post. The bolt is shown passing through the post and the bottom washer, where it is secured by the nut. Note that the washer is oversized to provide a solid grout lock. Once this is done, the entire assembly is placed in the finished floor in a grout bed. Once finished and the grout is cured, the posts and base shoe are immobile. The glass panels can then be added to finish the installation.

FIG. 10 is a view of the base-shoe and post assembly as set in a typical concrete slab. In this application, the slab 110 is formed with reinforcing bars 112 as normal. In the locations designated for posts, a 4-inch (100-mm) diameter, 4-inch (100-mm) deep core pocket 114 is formed in typical applications. This pocket accepts the post 5 as shown. The post is then secured in the pocket 114 by a bed of grout 15 as discussed above. Note also that this figure shows an end cap 4a installed on the end of the base shoe. Note that four screws 22 are used to hold the end cap 4a in place.

As shown in FIG. 1, at the top of the glass panels is a cap rail 2. The cap rail is made of extruded aluminum. Details of the rail and splice joints are shown in FIGS. 11-17. FIG. 11 shows the top rail 2 aligned with another section of rail 2′. A splice member 21 is shown inserted into the rail 2. In the preferred embodiment, the splice member 21 is secured into one end of the rail with epoxy. Only one end is secured to allow for thermal expansion. As shown, the splice member 21 has two grooves 24. These grooves are designed to fit around the extrusions 25 that are formed inside the top rail. See also FIG. 12, which is an inset detail of the tubing and the top rail extrusion.

FIG. 13 is a side view of the rail 2 and the splice 21 in place showing the splice aligned with a second piece of rail 2′. FIG. 13a is a front cross-section showing again how the splice 21 fits around the extrusions 25. FIG. 13b is an inset view of the splice and extrusion from a front view.

FIG. 14 is a detail showing the end cap 2a aligned with the rail 2. The end cap 2a is held on the rail 2 by screws 22 that pass through holes 26 formed in the end cap. The screws are screwed into the extrusions 25 that are formed in the rail 2 as discussed above.

FIG. 15 shows the details of the end cap 4a for the base shoe 4 here, four screws 22 pass through holes 27 in the end cap. The screws are screwed into sockets 19 formed in the base shoe, as discussed above.

FIG. 16 is a detail end view of the top rail 2. This view shows the relative dimensions of the rail.

FIG. 21 is a cross-sectional view of a piece of extruded rubber 13 used to protect the glass panels in the base.

FIG. 22 is a cross-sectional view of a piece of rigid PVC 11 used to protect the glass panels in the rail.
