In the table-storage position, the table assembly 104 is moved (such as, folded) towards the sub-mount assembly 110 in such a way that space underneath the table assembly 104 is reduced, at least in part (relative to the table-deployment position). In the table-deployment position, the table assembly 104 is moved (such as, folded) away from the sub-mount assembly 110 in such a way that space underneath the table assembly 104 is increased, at least in part (relative to the table-storage position).
The interlocking bracket assembly 112 includes a combination of: a first mounting bracket 114 and a second mounting bracket 116. The first mounting bracket 114 is configured to be fixedly connected to (and project from) the rail-mountable assembly 102. The second mounting bracket 116 is configured to be fixedly connected to (and project from) the sub-mount assembly 110. The first mounting bracket 114 and the second mounting bracket 116 are configured to be selectively slide engageable with each other. The first mounting bracket 114 and the second mounting bracket 116 are configured to transfer weight from the table assembly 104, the folding assembly 108 and the sub-mount assembly 110 toward the rail-mountable assembly 102 and the railings 902 of the handrail system 900. The transfer of the weight is done in such a way that the table assembly 104 remains operatively supported at the table-storage position and at the table-deployment position.
The mounting hardware 147 is configured to fixedly attach the interlocking bracket assembly 112 to the rail-mountable assembly 102. The mounting hardware 147 (such as a bolt and nut, etc.) is configured to fixedly attach the interlocking bracket assembly 112 to the sub-mount assembly 110. For instance, the mounting hardware 147 may be a 0.25 inch bolt with corresponding nuts (or any equivalent mounting hardware). It will be appreciated that there are options for fixedly attaching the interlocking bracket assembly 112. In accordance with the option as depicted in FIGS. 4a and 4b, the mounting hardware 147 is configured to fixedly attach the second mounting bracket 116 (of the interlocking bracket assembly 112) to the rail-mountable assembly 102, and the mounting hardware 147 is configured to fixedly attach the first mounting bracket 114 (of the interlocking bracket assembly 112) to the sub-mount assembly 110. Of course, in accordance with another option (not depicted but easy to understand nevertheless), the mounting hardware 147 is configured to fixedly attach the first mounting bracket 114 (of the interlocking bracket assembly 112) to the rail-mountable assembly 102, and the mounting hardware 147 is configured to fixedly attach the second mounting bracket 116 (of the interlocking bracket assembly 112) to the sub-mount assembly 110 (if so desired).
In general terms, the first mounting bracket 114 and the second mounting bracket 116 are configured to be selectively slide engageable with each other. The first mounting bracket 114 slides into the second mounting bracket 116 until the first mounting bracket 114 abuts the stop portion 111 (depicted in FIG. 3e) of the second mounting bracket 116 and thus stops further travel relative to the second mounting bracket 116; in this way, the first mounting bracket 114 is slide-engaged with the second mounting bracket 116. A lock mechanism (not depicted) may be mounted (if so desired) to the interlocking bracket assembly 112, and may be configured to lock the first mounting bracket 114 and the second mounting bracket 116 together once the first mounting bracket 114 and the second mounting bracket 116 are slide-engaged with each other. For instance, the lock mechanism may include a pin that may be engaged in holes defined by the first mounting bracket 114 and the second mounting bracket 116 once the first mounting bracket 114 and the second mounting bracket 116 are aligned with each other in the slide-engaged position (depicted in FIG. 4a).
Referring to both FIGS. 3e and 4a, the construction of the apparatus 100 is as follows:
Operation (A) includes fixedly connecting the second mounting bracket 116 to the rail-mountable assembly 102, by using the mounting hardware 147 (and corresponding nut) through the fastening holes 117 (depicted in FIG. 3e) defined by the second mounting bracket 116 and the fastening holes 146 (depicted in FIG. 3o) defined by the rail-mountable assembly 102 (once the fastening holes 117 and the fastening holes 146 are aligned together).
Operation (B) includes fixedly connecting the first mounting bracket 114 to the sub-mount assembly 110, by using the mounting hardware 147 (and corresponding nut) through the fastening holes 123 (depicted in FIG. 3e) defined by the first mounting bracket 114 and the fastening holes 128 (depicted in FIG. 3c) defined by the sub-mount assembly 110 (once the fastening holes 123 and the fastening holes 128 are aligned together).
Operation (C) includes fixedly attaching the folding assembly 108 to the sub-mount assembly 110 and to the table assembly 104 (using bolts or screws, etc.). As depicted, the first folding portion 127 of the folding assembly 108 is fixedly connected to the table assembly 104; the second folding portion 129 of the folding assembly 108 is fixedly connected to the sub-mount assembly 110.
Operation (D) includes fixedly connecting the rail-mountable assembly 102 to the railings 902. For instance, the rail-mountable assembly 102 is positioned on a selected length of the railings 902 (on a side of the railings 902). The mounting clip 139 is positioned on another side of the railings 902 opposite from the rail-mountable assembly 102. The carriage bolt 145 is positioned to pass through the slot 137 defined by (provided by) the rail-mountable assembly 102 (so that the flared head of the carriage bolt 145 abuts the side of the rail-mountable assembly 102). The carriage bolt 145 slides through the hole 141 defined by the mounting clip 139. The coupling nut 143 is threadably connected to the carriage bolt 145 and is tightened in such a way as to clamp down the rail-mountable assembly 102 to the railings 902. The mounting clip 139 is configured to span across at least two or more adjacently positioned instances of the railings 902 (depending on the requirements for supporting the weight of the apparatus 100 and the weight to be received by the table assembly 104, etc.).
Operation (E) includes slidably engaging the first mounting bracket 114 (that is fixedly attached to the sub-mount assembly 110) with the second mounting bracket 116 (that is fixedly attached to the rail-mountable assembly 102).
Now the table assembly 104 may be selectively moved or positioned between the deployed position as depicted in FIG. 4a and the storage position depicted in FIG. 4b. It will be appreciated that the table assembly 104 may be securely locked in the deployed position in order to safely secure the weight to be received by the table assembly 104 (from such items as plates, cutlery, etc.).
Referring to FIG. 4c (depicting a side view) along the line A-A of FIG. 4b, there is depicted an embodiment of the carriage bolt 145, the coupling nut 143 and the mounting clip 139 assembled so that the rail-mountable assembly 102 is fixedly attached to the railings 902. The carriage bolt 145 may include a rounded head portion. The head portion of the carriage bolt 145 has a diameter that is larger than the dimension or diameter of the slot 137. The carriage bolt 145 includes a hex portion 151 extending from the head portion. The hex portion 151 (also called a hexagonal-shaped outer surface) is configured to be slidable along the slot 137 between the side walls of the rail-mountable assembly 102 (it will be appreciate that in this manner and arrangement, the carriage bolt 145 does not inadvertently turn or rotate in response to tightening of the coupling nut 143 to the distal end of the carriage bolt 145). It is understood that the hex portion 151 is configured to lock in a position once the hex portion 151 is urged to rotate along the rotation axis extending through the carriage bolt 145. The cross sectional profile of the hex portion 151 is depicted to the left side of FIG. 4c (for improved clarity regarding the hex portion 151).
Referring to FIG. 4d (depicting a top view), there is depicted an embodiment of the apparatus 100 in which the apparatus 100 is depicted in the storage position. In accordance with an option, the slot 109 is defined by the sub-mount assembly 110 and is positioned proximate to the head of the carriage bolt 145, and the slot 109 is configured to accommodate the round head of the carriage bolt 145 for the case where there may be a possible interference between the head portion of the carriage bolt 145 and the sub-mount assembly 110.
Referring to FIGS. 4e and 4f (depicting cross-sectional side views through line B-B of FIG. 4f), there is depicted an embodiment of the apparatus 100. FIG. 4e depicts the table-deployment position of the table assembly 104, in which the table assembly 104 is moved (such as, folded) away from the sub-mount assembly 110 in such a way that space underneath the table assembly 104 is increased, at least in part. In this way, items (such as plates, cutlery, etc.) may be positioned on the table assembly 104, and the table assembly 104 may then receive weight from user items (when desired by the user). FIG. 4f depicts the storage position of the table assembly 104, in which the table assembly 104 is moved (folded) towards the sub-mount assembly 110 in such a way that space underneath the table assembly 104 is reduced, at least in part. In this manner, additional space may be provided next to the railings 902 (when desired by the user). It will be appreciated that the vertical height of the rail-mountable assembly 102 and the sub-mount assembly 110 may be the same. The vertical height of the interlocking bracket assembly 112 may vary to be the same as or smaller than the rail-mountable assembly 102.
With reference to FIG. 4e, the slot 109 (also depicted in FIG. 3b) is defined by the sub-mount assembly 110; the slot 109 is configured to accommodate the flared head of the carriage bolt 145 once the carriage bolt 145 is positioned to clamp the rail-mountable assembly 102 to the railings 902 (in accordance with an option where the flared head of the carriage bolt 145 may be relatively large).
Referring to FIG. 4g (depicting a cross-sectional side view through line B-B of FIG. 4f), there is depicted an embodiment of the apparatus 100. FIG. 4g shows the case where the first mounting bracket 114 and the second mounting bracket 116 of the interlocking bracket assembly 112 are slidably engaging with each other (along a direction that is parallel to the railings 902) along a vertical direction relative to the floor 910. It will be appreciated that once the first mounting bracket 114 and the second mounting bracket 116 are operatively aligned with each other (as depicted in FIG. 4e), they may be locked together (if so desired).
Referring to FIG. 4h (depicting a cross-sectional side view through line B-B of FIG. 4f), there is depicted an embodiment of the apparatus 100. FIG. 4h shows the case where the first mounting bracket 114 and the second mounting bracket 116 of the interlocking bracket assembly 112 are separated from each other. For this case, the table assembly 104 may be placed, for example, in an interior of a house or a garage while the rail-mountable assembly 102 may remain attached to the railing 902. As depicted in FIG. 4h, the first mounting bracket 114 and the second mounting bracket 116 are disengaged from each other.
