"この" vs "こちらの" with regard to implied plurality

Question

この

この文型{ぶんけい}は文{ぶん}の作{つく}り方{かた}を示{しめ}している。

こちら

こちらの文型は文の作り方を示している。

1. In all contexts, "この文型..." refers to just one grammatical pattern?
2. "こちらの文型..." might refer to one grammatical pattern, or possibly a list of grammatical patterns (context decides which)? With no context, I feel ambiguity.

as a side note:
This might be because " この " can be made explicitly plural " これらの... , however " こちららの... " would just sound too strange?

Answer 1

1. Yes, it refers to one or collective one.
2. こちら can be (1) "this one" or "our side" when the other one ("that one" or "their side") is already present in the context, or (2) a polite form of これ or これら. The latter usage wouldn't be decent in your context. So, that こちらの is "this" opposed to the aforementioned.
