Tool-Less Blade Clamping Apparatus for a Reciprocating Tool

Номер: US20130193653A1
Автор: Gary Sinclair, Gavin Wright, Marc Vincent Marini, Matthew Carr, Vance E. Roe
Принадлежит: ROBERT BOSCH GMBH, Robert Bosch Tool Corp

Several preferred embodiments are disclosed for a tool-less blade clamping apparatus for a reciprocating tool of the type which has a reciprocating plunger which has a tool attachment receiving slot for receiving a tool attachment of the type that has a shank portion. The clamping apparatus has an unclamped position and a clamped position. In the unclamped position, a tool attachment can be easily inserted and when it is in its clamped position, the tool attachment is securely retained. The preferred embodiments have at least one spring biasing the apparatus toward the clamped position, a releasable retaining mechanism for holding the apparatus in its unclamped position after being placed in that position. When the blade shank portion is inserted into the slot a predetermined distance, the shoulders of the shank portion release the retaining mechanism to move it to its clamped position. When a blade is to be removed, the clamping apparatus needs only to be moved to its unclamped position by manually rotating the outer sleeve or collar, and the blade is normally ejected from the mechanism by contact with the blade shoulders as it reaches its unclamped position.

Apparatus for converting between rotary motion and linear motion includes a rotatable piece being rotatable about an axis; at least one member having a linking surface facing the rotatable piece and arranged for movement relative to the axis of the piece; and a means for linking the linking surface of the respective member and the surface of the rotatable piece, so that rotational motion of the rotatable piece causes linear movement of the at least one member, and/or linear movement of the at least one member causes rotational motion of the rotatable piece. A sawing device may include said apparatus for cutting by repetitive reciprocating cutting action. A saw blade may be configured for such a sawing device. 1. Apparatus for converting rotary motion to linear motion or linear motion to rotary motion , comprising:a rotatable piece having a surface, the piece being rotatable about a central axis thereof and the surface having a first cooperating portion therein or thereon;at least one member having a linking surface facing the surface of the rotatable piece and arranged for restricted movement at least in part laterally relative to the central axis of the piece; andlocated between the surface of the rotatable piece and the or each member, a link configured to link the surface of the member and the surface of the rotatable piece, wherein the linking surface of the or each member has a second cooperating portion extending diagonally thereon or therein relative to the direction of movement of the member, and wherein the link links the first cooperating portion to the second cooperating portion;wherein the link, the first cooperating portion and the second cooperating portion are configured to cooperate so that rotational motion of the rotatable piece causes repetitive reciprocating movement of the at least one member, or repetitive reciprocating movement of the at least one member causes rotational motion of the rotatable piece.2. The apparatus of claim 1 , wherein the ...
