Description

TECHNICAL FIELD

Generally, this disclosure relates to mechanics. More particularly, this disclosure relates to various technologies for interlocking structures.

BACKGROUND

In this disclosure, where a document, an act, and/or an item of knowledge is referred to and/or discussed, then such reference and/or discussion is not an admission that the document, the act, and/or the item of knowledge and/or any combination thereof was at a priority date, publicly available, known to a public, part of common general knowledge, and/or otherwise constitutes any prior art under any applicable statutory provisions; and/or is known to be relevant to any attempt to solve any problem with which this disclosure may be concerned with. Further, nothing is disclaimed.

Signage, whether static or dynamic, is used to present content, whether outdoors or indoors. The signage can be mechanic, such as a split-flap display, a flip-disc display, or a roll-sign. Additionally or alternatively, the signage can be electronic, such as an electronic sign or an electronic display. Although the content often presented via the signage is advertising, the signage can be used to present any content for any informational purposes, directional purposes, identification purposes, or safety/regulatory purposes.

Since the signage can have various purposes, the signage should be properly installed and maintained. However, some installation techniques or maintenance techniques are often time consuming or laborious due to signage structure or location, thereby requiring various usages of individual component fitting, fastening schemes, drilling, or others. For example, when a technician needs to selectively fasten/unfasten various bolts within a signage cabinet, then the technician typically needs to perform various time consuming and laborious operations, such as cabinet alignment and module removal/reinstallation.

Accordingly, at least in a signage industry, there is a need to address at least one of such inefficiencies.

FIG. 11 shows a side view of an embodiment comprising a pair of signage units before stacking, where the signage units are aligned via an alignment pin according to this disclosure. FIG. 12 shows a cross-sectional view of an embodiment comprising a pair of signage units before stacking, where the signage units are aligned via an alignment pin according to this disclosure. Note that the alignment pin 174 extends through the opening of the first bridge portion 130, yet the first projection 144 and the second projection 170 are offset along a vertical plane. Likewise, note that the first wall portion 128 is not aligned with the lower cabinet 104, i.e., the first wall portion 128 is offset with the lower cabinet 104 along a vertical plane. Moreover, note that the upper cabinet 104 is raised over the lower cabinet 104, such as via a crane, with the upper cabinet 104 comprising the first unit 122 integrated or unitary therewith.

FIG. 13 shows a cross-sectional view of an embodiment comprising a pair of signage units stacked before interlocking according to this disclosure. FIG. 14 shows a cross-sectional view of an embodiment comprising a pair of signage units stacked after interlocking according to this disclosure. FIG. 15 shows a cross-sectional view of an embodiment comprising a pair of signage units stacked after interlocking according to this disclosure. FIG. 16 shows a cross-sectional view of an embodiment comprising a pair of signage units stacked after interlocking according to this disclosure. The first U-shaped portion 124 is moved such that the second projection 170 is positioned between the first leg portion 134 and the second leg portion 142 without contacting the first projection 144 and such that the second projection 170 extends toward the first base portion 140 and such that the second projection 170 is positioned between the first base portion 140 and the second base portion 166. Note how the tail portion 146 and the tail portion 169 are not aligned along a vertical plane. Likewise, note that since the first wall portion 128 is not aligned with the lower cabinet 104, i.e., the first wall portion 128 is offset with the lower cabinet 104 along a vertical plane, a gap 176 exists.

As the upper cabinet 104 is supported via the lower cabinet 104, while the gap 176 exists and the first projection 144 is not in contact with the second projection 170, the upper cabinet 104 or the first unit 122 or the lower cabinet 104 or the second unit 150 is operated in such a way that the first projection 144 is moved toward the second projection 170 such that the first projection 144 contacts the second projection 170 between the first leg portion 134 and the second leg portion 142 and such that the second projection 170 is positioned between the first base portion 140 and the second base portion 166. Note that such movement is enabled via the opening of the first bridge portion 130 being shaped to allow for such movement, such as laterally, for instance via the opening of the first bridge portion 130 being oval or cam shaped, while the lower part of the alignment pin 174 being sized for such movement, such as via having a diameter smaller than the middle part. Consequently, since the first projection 144 is the female portion and the second projection 170 is the female portion, the first projection 144 and the second projection 170 mate and thereby securely interlock or engage with each other. Therefore, when the nuts 118 are fastened to the bolts 116, as the bolts 116 extend through the L-shaped bracket 110 or the strut bracket 202, as disclosed herein, and as the bolts 116 engage the bolt carriers 120 within the first C-shaped portion 124 and the second C-shaped portion 152, respectively, then such fastening applies or exerts a force in a direction away from the second projection 170. This force enables a secure interlocking of the upper cabinet 104 to the lower cabinet 104, or vice versa.

Note that in some embodiments as the upper cabinet 104 is supported via the lower cabinet 104, while the gap 176 exists and the first projection 144 is not in contact with the second projection 170, the upper cabinet 104 or the first unit 122 or the lower cabinet 104 or the second unit 150 is operated in such a way that the second projection 170 is moved toward the first projection 144 such that the first projection 144 contacts the second projection 170 between the first leg portion 134 and the second leg portion 142 and such that the second projection 170 is positioned between the first base portion 140 and the second base portion 166. Further, note that although the first bridge portion 130 or the first projection 144 is laterally moved in a frictional or a slidable manner with respect to the lower cabinet 104, such as via the second unit 150, in some embodiments, the first bridge portion 130 or the first projection 144 can be moved in a non-frictional or a non-slidable manner, such as when a gap along a vertical plane exists, for instance between the lower cabinet 104 and at least one of the first bridge portion 130 or the first projection 144. For example, such gap can be less than 2 centimeters in height measured along a vertical plane. Also, after the lower cabinet 104 and the upper cabinet 104 are securely interlocked via the first unit 122 and the second unit 150, the alignment pin 174 can be removed such that the alignment pin 174 does not extend at least through the first bridge portion 130. Moreover, note that although various interlocking methods disclosed herein are described in a context of vertical stacking, in some embodiments, various interlocking methods disclosed herein can be employed in a cabinet positioning along a horizontal plane, such as adjacent to each other, or even along a diagonal plane, such as via outward corner portions.
