摘要： A collapsible square constructed according to the principles of the present invention includes a first elongated rigid leg having first and second ends and a second elongated rigid leg having first and second ends. The second elongated rigid leg is pivotally connected at its first end to the first end of the first elongated rigid leg. The collapsible square further includes a hypotenuse member comprising two elongated rigid leg portions. A first of the leg portions of the hypotenuse member and a second of the leg portions of the hypotenuse member have their first ends pivotally connected to the second end of the first elongated rigid leg and the second end of the second elongated rigid leg, respectively. The first of the leg portions and the second of the leg portions have second ends thereof connected to one another in a manner which permits the hypotenuse member to be folded. The first leg, the second leg, and the hypotenuse member are connected to one another so as to be movable between 1) a storage position wherein the first leg, the second leg, and the hypotenuse member are disposed in linear overlapping relation with one another, and 2) a deployed position wherein the first leg, the second leg, and the hypotenuse member form a right triangle. A releasable lock structure disposed at the second ends of the first and second leg portions is constructed and arranged to releasably lock the first leg, the second leg and the hypotenuse member in the deployed position.
摘要翻译：根据本发明的原理构造的可折叠方形包括具有第一端和第二端的第一细长刚性腿和具有第一和第二端的第二细长刚性腿。第二细长刚性腿在其第一端处枢转地连接到第一细长刚性腿的第一端。可折叠正方形还包括包括两个细长的刚性支脚部分的斜边构件。斜边构件的第一腿部和斜边构件的第二腿部的第一部分的第一端分别枢转地连接到第一细长刚性腿的第二端和第二细长刚性腿的第二端。腿部中的第一腿部和第二腿部的第二端部的第二端部以允许斜边部件折叠的方式彼此连接。第一腿部，第二腿部和斜边部件彼此连接，以便能够在1）与第一腿部，第二腿部和斜边部件之间以彼此成直线的重叠关系设置的存储位置之间移动以及2）展开位置，其中所述第一腿，所述第二腿和所述斜边构件形成直角三角形。设置在第一和第二腿部的第二端处的可释放的锁定结构被构造和布置成将第一腿部，第二腿部和斜边部件可释放地锁定在展开位置。

摘要： A chalk line device includes a housing and a chalk line stored in the housing. The chalk line terminates in a hook at one end and the hook is disposed outside of the housing. The housing may include a side wall with a depression formed therein that is shaped to receive the hook for storage. The depression has an edge that allows the hook to securely engage. The housing may also include a translucent window for allowing the user to check the level of chalk in the chalk line device. The translucent window forms at least a portion of a wall of the housing. The translucent window can be made, for example, of a plastic and can be integrally formed with the housing.
摘要翻译：白垩线装置包括存储在壳体中的壳体和粉笔线。粉笔线在一端终止于一个钩子，钩子设在外壳的外面。壳体可以包括其中形成有凹陷的侧壁，其被成形为接收用于存储的钩。凹陷具有允许钩子牢固地接合的边缘。壳体还可以包括半透明窗口，用于允许用户检查粉笔线设备中的粉笔的水平。半透明窗构成外壳壁的至少一部分。半透明窗可以由例如塑料制成，并且可以与壳体一体形成。
