The present disclosure relates to the field of landscaping and garden tools, and, more particularly, to landscaping accessories and related methods.
The landscaping industry is a large and robust industry worldwide. Although the demand for commercial landscaping is quite large, the residential landscaping industry is arguably more robust and diverse. In fact, the residential landscaping industry has spawned several large business sectors, such as the residential landscaping maintenance industry, the residential irrigation maintenance industry, and the landscaping device industry (i.e. lawn mowers, landscaping accessories, lawn care items).
The landscaping accessories industry is quite mature and spans a wide continuum of devices, varying from portable irrigation devices to manual cultivation tools. Once such landscaping accessory is a frost shield for plants and small trees. Some plants and small trees may suffer damage when the ambient temperature drops below a threshold temperature (e.g. the freezing point of water: 32° F. or 0° C.). To protect the plants and small trees from damage, the frost shield is deployed thereover. In most approaches, the frost shield is a simple weather proof blanket for the plants and small trees.
On drawback these typical approaches is inconvenience. In particular, the frost shield must be deployed and removed regularly to keep the plants and small trees in a healthy state. Of course, in many applications, the residential user may not redeploy the frost shield promptly or leave the frost shield on too long, each scenario damaging the plant.
Generally, a frost shield device may include a base comprising a plurality of blocks. At least some of the plurality of blocks each may define a first through passageway and a second through passageway. The frost shield device may comprise a plurality of poles. Each pole may have a first end to be received by one of the first through passageway and the second through passageway, and a second end. The frost shield device may also include a top ring coupled to the second ends of the plurality of poles, and a cover layer configured to extend from the base to the top ring, thereby covering a plant within the base.
In particular, the plurality of blocks may comprise a plurality of cap blocks, a plurality of base blocks, and a plurality of medial blocks between the plurality of cap blocks and the plurality of base blocks. The frost shield device may also comprise a plurality of plug connectors carried within the first through passageway and the second through passageway of each cap block. In some embodiments, each of the plurality of plug connectors may include a lower body defining a plurality of lower radial protrusions, an upper body defining an eyelet, and a disc-shaped medial portion between the lower body and the upper body.
Furthermore, the frost shield device may also include a plurality of connectors carried within the first through passageway and the second through passageway of each base block and medial block and vertically coupling adjacent blocks. Each of the plurality of connectors may include a lower body defining a plurality of lower radial protrusions, an upper body defining a plurality of upper radial protrusions, and a disc-shaped medial portion between the lower body and the upper body.
Each base block may comprise a first end and a second end opposing the first end defining an interlocking interface. Each of the first and second through passageways may have an outer diameter, and an inner diameter less than the outer diameter. Each of the first and second through passageways may have a longitudinal channel extending partially therein.

In the illustrated embodiment, the first through passageway 233a, 253a and the second through passageway 233b, 253b of each medial block 229a-229b and each cap block 234 have identical features to the first through passageway 239a. In other embodiments, the first through passageway 233a, 253a and the second through passageway 233b, 253b of each medial block 229a-229b and each cap block 234 have similar features, but include a pair of first and second opposing medial channels 252a-252b. More specifically, the first through passageway 233a, 253a and the second through passageway 233b, 253b would receive and interface lock with connectors 227a-227e and/or plug connectors 226 from opposing longitudinal sides, thereby providing a more mechanical strong connection. Of course, in some embodiments, such as the illustrated example, the first and second opposing medial channels 252a-252b are sized so to that the plurality of lower radial protrusions 255a-255b and the plurality of upper radial protrusions 254a-254b can concurrently fit therein.
As will be appreciated, the frost shield device 220 is assembled as now described. First, a first layer of the base blocks 231a-231c is assembled in the desired form for the base 221 (e.g. the illustrated circle shape). The adjacent first and second ends 238, 230 of the base blocks 231a-231c are coupled together via the interlocking interface.
Secondly, the plurality of connectors 227a-227e is inserted into the first through passageway 239a and the second through passageway 239b of the assembled base blocks 231a-231c. In particular, the lower body 243b of each connector is inserted in a respective through passageway 239a-239b so that the plurality of lower radial protrusions 255a-255b are aligned with the first and second opposing longitudinal channels 250a-250b and pass therethrough.
Once the plurality of lower radial protrusions 255a-255b reach a depth equal to the first and second opposing medial channels 252a-252b, the respective connector is rotated for a twist lock interface. In some embodiments, the medial blocks 229a-229b may be fitted over the upper body 243a of the connectors 227a-227e first, and then using a specialized wrench, the connector 227a-227e is rotated to lock the plurality of lower radial protrusions 255a-255b and the plurality of upper radial protrusions 254a-254b into their respective ones of the first and second opposing medial channels 252a-252b.
The medial blocks 229a-229b and the cap blocks 234 are assembled in similar fashion. Once the cap blocks 234 are fitted over the medial blocks 229a-229b, the plug connector 226 is inserted in some of the first and second through passageways 253a-253b of each cap block (except for those passageways intended to host a pole 222). In the other first and second through passageways 253a-253b, the pole 222 is inserted therein. Since the connectors 227a-227e and the plug connectors 226 include through passageways 245, 260, the pole can extend through them.
Another aspect is directed to a method of making the frost shield device 220. The method comprises forming a base 231 comprising a plurality of blocks 234, 229a-229b, 231a-231c. At least some of the plurality of blocks 234, 229a-229b, 231a-231c each defines a first through passageway 239a, 233a, 253a and a second through passageway 239b, 233b, 253b. The method comprises forming a plurality of poles 222, each pole having a first end to be received by one of the first through passageway 239a, 233a, 253a and the second through passageway 239b, 233b, 253b, and a second end, and coupling a top ring to the second ends of the plurality of poles. The method further comprises forming a cover layer configured to extend from the base 221 to the top ring, thereby covering a plant within the base.
