## Background
PRIORITY CLAIM AND RELATED APPLICATIONS
This non-provisional application claims the benefit of priority from application U.S. Ser. No. 62/258,017 filed on Nov. 20, 2015. Said application is incorporated by reference in its entirety.


BACKGROUND OF THE INVENTION
1. The Field of the Invention
The present invention is directed generally to a snow block erector set. More specifically, the present invention is directed to a snow block erector set capable of aiding in forming large snow blocks at more than one level.
2. Background Art
U.S. Pat. No. 3,816,048 to Berry et al. (Hereinafter Berry) discloses a two-piece mold for producing shaped units of formable material such as snow and the like, and for handling and positioning the shaped units. One piece of the mold provides three sides and at least one open end, and the second piece provides the fourth side and an end closure. The two mold pieces are slidably mated along their edges to an assembled condition in which the first and second pieces are secured to provide an open topped, closed bottom mold. After snow or other shape-holding material is packed into the mold through the open top, and sets its shape, the filled mold is inverted. With the second piece held in place, the three-sided element is drawn past the fixed end closure which is now positioned at the top until the three-sided element is separated. The second element including the end closure is moved laterally from the resulting block of shaped material to leave the shaped unit standing free where initially positioned. The first and second elements of the mold can then be mated for reuse. Berry's mold does not permit the removal of each side wall or end wall from a formed snow block individually so as not to disturb the formed snow block. In addition, Berry requires inversion of its mold to release the formed snow block.
U.S. Pat. No. 3,685,942 to Shaffer (Hereinafter Shaffer) discloses a device and method for use in producing compacted blocks of snow which can be assembled and shaped into sculptured works or other snow structures, the device comprising a scoop in the nature of an open ended mold having four tapered closed sides and a proximal end wall defining a mold cavity. The proximal end wall contains air holes and a handle to be gripped by the user. Snow blocks are formed in a continuous manner by forcing the open end of the scoop into snow, compacting the snow in the mold cavity of the scoop when the scoop is full of snow by pushing the scoop toward the ground into more snow and jarring the compacted snow from the mold cavity after elevating the scoop. Again, Shaffer's block does not permit the removal of each side wall or end wall from the formed snow block individually so as not to disturb the formed snow block.
U.S. Pat. No. 3,572,625 to Willliamsen (Hereinafter Willliamsen) discloses a mold for forming blocks of snow including four right angularly related walls, an open top and an open bottom. One of the walls is slightly inclined outward so as to facilitate the removal of the block. Two of the opposed walls are provided with bumpers to enable a bouncing of the mold in shaking the block loose therefrom. Williamsen's mold is designed be held by hand such that it can be shaken to release the formed block. The present snow mold is capable of holding much more snow for making a much larger block and therefore is not suitable to be held in hand. Williamsen's mold also does not permit the removal of each side wall or end wall from the formed snow block individually so as not to disturb the formed snow block.
U.S. Pat. Pub. No. 2010/0230842 of Pendergast (Hereinafter Pendergast) discloses a four-sided open top forming mold body for material such as snow or sand having peripheral walls with in-turned flanges at a bottom thereof, a mold bottom adapted to rest against the in-turned flanges, inter-engaging edge portions of the bottom and configurations on the walls retaining the bottom in place until application of a force sufficient to overcome the retention whereby the bottom can push the molded material out of the mold, and the bottom can be re-snapped into position at the bottom before another material molding, the mold body adapted to receive an open ended receptacle such as a sandbag having a greater length than the height of the mold such that the receptacle open end can be closed when the receptacle is filled with material to the top of the mold. Pendergast's mold also does not permit the removal of each side wall or end wall from the formed snow block individually so as not to disturb the formed snow block.
U.S. Pat. No. 4,154,423 to Crock (Hereinafter Crock) discloses two molds, each comprising an open top container having side walls, end walls, and a bottom, are provided for forming blocks of snow or ice which are used to form a complete domed structure such as an igloo. The configuration of one mold is such that blocks formed by it will fit together to form a circular upwardly converging wall, and the configuration of the other mold is such that blocks formed by it will fit together to form a circular dome which rests on the upper surface of the wall to complete the structure. Crock discloses molds suitable for making blocks of a particular shape for building an igloo. Once formed, the blocks of Crock can only be released by inverting the molds.
Thus, there is a need for a snow block erector set adapted for the construction of large snow blocks where the erector set is transportable and set up without undue effort. There should also be no inversion of snow blocks to position the snow block in place.

PARTICULAR ADVANTAGES OF THE INVENTION
The present erector set aids one in forming large snow blocks expediently and easily. Multiple erector sets may be combined to construct large forms to receive snow to yield snow walls. The erector set can be used by a single individual without requiring additional tools for forming snow. The only tool that may be required is a tool for moving snow into the space formed of the erector set for receiving snow. The erector set does not need to be turned upside down to expel a formed block. A snow block can be and is preferably formed in place. The present erector set can be dismantled for transport by individuals or in vehicles and storage without taking up a significant amount of space.
DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
The term “about” is used herein to mean approximately, roughly, around, or in the region of. When the term “about” is used in conjunction with a numerical range, it modifies that range by extending the boundaries above and below the numerical values set forth. In general, the term “about” is used herein to modify a numerical value above and below the stated value by a variance of 20 percent up or down (higher or lower).
FIG. 1 is a top perspective view of one embodiment of the present snow block erector set 2. FIG. 2 is a top perspective view of one embodiment of the present snow block erector set 2, depicting guide pins 34 configured for retaining end walls 6. FIG. 2A is a partial top view of a top corner of a present snow block erector set 2 depicting one embodiment of a channel within which an edge of an end wall is secured. The snow block erector set 2 includes a pair of substantially rectangular side walls 4 having a length 42 and a width 44, a pair of substantially rectangular end walls 6, a pair of brace bars 8 and in one embodiment, a plurality of channels 40 for receiving side edges of end walls 6. Each side wall 4 includes a top edge, a bottom edge, two side edges, an outside surface and an inside surface. Each side edge of each side wall 4 connects one end of the top edge of the side wall to one end of the bottom edge of the side wall to form a top corner and a bottom corner, respectively. Each side wall 4 further includes an aperture 16 and lock 10 pair disposed substantially on a top corner. Each end wall 6 has two side edges. Each brace bar 16 has two ends. The length 42 of a side wall 4 preferably ranges from about 18 inches to about 36 inches and the width 44 of a side wall 4 preferably ranges from about 12 inches to about 30 inches.
The present snow block erector set 2 can function without channels that are disposed on the side walls when it is used to form snow blocks at a bottom course of a soft base. Without channels, the end walls are preferably urged down and lodged against the soft base for stability. Each channel 40 is disposed substantially along each of the side edges and on the inside surface of each of the side walls. In one embodiment (as shown in FIGS. 1 and 2), each channel is formed of a combination of a guide 20 and a guide pin 34 spaced apart laterally from the guide 20 to create a channel space within which one of the side edges of one of the end walls 6 is disposed. In one embodiment, only one guide pin 34 is used and biasly disposed toward the top edge of a side wall as the snow that is subsequently disposed in the space formed in an erected set tends to push the bottom portion of an end wall outwardly, negating the need for a guide pin for the bottom portion of the end wall. The guide pins 34 can also prevent installed end walls 6 from toppling towards themselves within the space outlined by the side and end walls 4, 6. Formed snow blocks may have inadvertent impressions left by these guide pins 34. However, these impressions are rather small and easily patched if the appearance of a smooth side surface of a snow block is intended.
In another embodiment, a channel 40 includes an elongated depressed path within which one of the side edges of one of the end walls 6 is disposed as shown in FIG. 2A. In this embodiment, the channel 40 is preferably shallow with its mouth tapering outwardly to avoid collection of snow and the need to remove snow collected from the channel 40 while in use. The use of channels 40 as shown in FIG. 2A eliminates the need for guides configured to hold end walls in place as collected snow within the space tends to urge against the end walls from within the space.
In use, the pair of side walls 4 are aligned side by side and in parallel with their inside surfaces of the facing one another and each aperture 16 of an aperture 16 and lock 10 pair substantially aligned with an aperture 16 of a corresponding side wall 4. The ends of each brace bar 8 are configured to be inserted through the aligned apertures 16 of the pair of side walls such that the pair of side walls can be supported upright. Upon securing the side walls with the brace bars 8, each end wall 6 is secured to the pair of side walls 4 by disposing each side edge of each end wall 6 within one of the channels 40 to form a rectangular space for receiving snow with four walls, i.e., two opposingly disposed side walls 4 and two opposingly disposed end walls 6.
In one embodiment, the present snow block erector set 2 further includes at least one stacking post 24 configured to protrude from the top edge of each side wall 4 and substantially in parallel configuration with the side edges of the side wall 4. In one embodiment, the present snow block erector set 2 further includes at least one stacking aperture 26 disposed on the bottom edge of the each side wall 4. Each stacking aperture 26 is configured to receive at least one stacking post 24 of a snow block erector set 2 disposed below the side wall 4.
In one embodiment, a lock of each of the aperture 16 and lock 10 pairs is a slide bolt lock as shown in FIGS. 1-2, 3 and 4-6. A slide bolt lock essentially includes a lock shaft 12 configured for slidable movement in a path bounded by one or more holders 30 and can assume a locked position and an unlocked position and a handle 14 for facilitating manipulation of the lock shaft 12. In the embodiments shown in FIGS. 1-2, 3 and 4-7, a locked position is achieved when a lock shaft 12 is inserted or engaged in a retainer, e.g., a hole 32, disposed substantially on one end of a brace bar 8, serving as a travel limit to prevent movement of the corresponding top corner of a side wall 4 from sliding off of the end of the brace bar 8. With a slide bolt lock, the locking mechanism is already made available and attached to the side wall such that a user of a set 2 does not need to locate such part during use. In another embodiment, a lock of each of the aperture and lock pairs is a pin for insertion and removable retention within a hole 32. The pin can additionally be tethered to a side wall 4 to ensure the pin is in close proximity and ready for use when it is needed.
In one embodiment, the present snow block erector set further includes a carry strap 22 disposed substantially on the top edge of on the outside surface of each of the side walls 4. In transporting the present erector set 2, the side walls 4 are brought close together and disposed symmetrically, with their inside surfaces facing one another, to dispose the carry straps 22 in a position for easy grasps of a user's hand.
FIG. 3 is a side view of one embodiment of a side wall of the present snow block erector set, depicting the lock in an unlocked position. FIG. 3A is a partial top perspective view of one top corner of a present snow block erector set, depicting a corner that is unlocked. It shall be noted in the unlocked position, the handle 14 may be tucked in a slot 18 neatly just as it may in the locked position, e.g., as shown in FIGS. 1 and 2. It may also be shown that when not in use, one or more end walls 6 may be tucked in the space between a bracket 28 and an outside surface of a side wall 4 such that they may be transported or stored along with the side wall 4.
FIG. 4 is a side view of two snow block erector sets, depicting the top snow block erector set aligned to be lowered and engaged with the bottom snow block erector set.
FIG. 5 is a side view of two snow block erector sets, depicting the top snow block having been lowered and engaged with the bottom snow block erector set to form a snow block erector set twice the height as achieved using only one snow block erector set. It can be seen that, in order to build a snow block that is even taller, one or more sets 2 may be stacked atop the two already stacked sets 2. It is also conceivable that, in order to build blocks in the lengthwise direction of the already built blocks, one or more sets 2 may be further erected. In connecting one or more new blocks to one or more existing blocks laterally, one of the end walls 6 of each newly erected set 2 will not be used such that newly poured snow in each newly erected set can be formed to connect with existing blocks.
FIG. 6 is an end view of two stacked snow block erector sets 2. Each of the substantially rectangular end walls 6 includes a length 48 and width 46. The length 48 of each end wall 6 ranges from about 12 inches to about 30 inches and the width 46 of each end wall 6 ranges from about 12 inches to about 24 inches.
FIG. 7 is a top perspective view of snow blocks formed using one or more present snow block erector sets. In this example, a total of six blocks have been formed. Four of the six blocks 36 are formed in a first plane and two 36 are formed in a second plane that is roughly perpendicular to the first plane. This structure may be formed using only one erector set or multiple erector sets. Multiple erector sets may be erected first such that the spaces formed of erected sets can be filled all at once or one erector may be used at a time to construct one snow block at a time to add to the structure. As disclosed elsewhere herein, laterally constructed snow blocks may be built with laterally disposed blocks in contacting fashion. However, for the two blocks which are disposed at about right angle to the four blocks, depending on the sequence in which the groups of blocks was built, space may need to be allocated between the two groups as the length of an individual block differs from the width of an individual block. Therefore, all walls 4, 6 of an erector set 2 may be required in constructing an adjoining block that is not geared towards extending the existing blocks laterally, e.g., when the groups of four blocks is constructed first. However, this is not a concern as loose snow may be used to fill the gap to form a seam 38 to close the gap between the two groups if desired. If the group of two blocks had been constructed first, no seam will be necessary as one or two blocks of the group of four blocks simply extend from the group of two blocks without the use of an end wall as disclosed elsewhere herein. A present erector set is preferably assembled in place as there are components of the erectors that are not securely attached to one another to allow such erected set to be assembled at one location and moved to a second location for use. In some instances, in using more than one erector set as a single construction unit, a first erector set is preferably filled first to provide sufficient weight and integrity to the erector set such that a second erector set that is assembled on top of the first may already have a strong base to support the second erector set and the block that is being built on top of the first bottom block. In forming a block, snow is incrementally dumped and compacted, e.g., with a shovel, in the space formed from the side and end walls. When the space is sufficiently filled and the snow compacted, the assembly may be dismantled by first unlocking the brace bars such that the brace bars may be released from the side walls. The end walls may then be readily removed as they will have no support once the side walls have been removed.
In one embodiment, at least one of the substantially rectangular side walls and the substantially rectangular end walls is constructed from a non-moisture absorbent material, e.g., polycarbonate or another plastic material. Although less desirably so, the side walls may alternatively be constructed from a wooden material, e.g., plywood. Although the present erector set is configured for the purpose of holding snow, it is conceivable that the erector can be used as a form for concrete, foam and other materials.
FIG. 8 is a top perspective view of one embodiment of the present snow block erector set, depicting guide pins 34 configured for retaining end walls 6 and supporting dividers 56. If a large snow block is unnecessary or if smaller snow blocks are desired, the space within the snow block erector set may be subdivided using one or more dividers 56. As shown herein, with two dividers 56, three smaller snow blocks may be formed. Upon being formed, the smaller blocks may be moved and used elsewhere. Further disclosed is a compactor useful for compacting the snow 54 placed within the erector set such that formed blocks can be made denser and stronger. In use, the handle 52 of the compactor is simply held in a hand of a user with its impact head 50 impacted repeatedly against the snow 54 disposed within the erector set.
FIG. 9 is a top perspective view of one embodiment of the present snow block erector set depicting a brace 60 configured for further securing one end of the present snow block erector set. FIG. 10 is a top perspective view of one embodiment of the present snow block erector set depicting a brace 60 having been disposed at one end of the present snow block erector set to secure the same. In this embodiment, a notch 58 is disposed on each side edge of a side wall 4. It shall be noted that such notches 58 are only shown on one end of the erector set. Such features can easily be applied to the opposite end of the erector set. In securing the side walls at one end of the erector set, a brace 60 is provided. The brace 60 is essentially a bar having two notches 62, each configured to be removably coupled to a notch 58 of a side wall. Each brace 60 adds stability to the erector set, especially when it is filled with snow, thereby allowing thinner and hence lighter side walls to be utilized.
