Quick release fastener for a band saw

Abstract

A quick release fastener for a hand-operated band saw with a saw band run on wheels in a housing, which has a base tray and a hinged lid and on which there is a handle. The handle is fixed to an upper angled edge of the lid and located below the handle there is a spring-loaded handle bar with two bent ends. The one end is fixed at the edge of the lid and the other end engages in a groove in the base tray through a recess in the edge.

Claims

1. A quick release fastener system comprising: a base component, a hinged component, a handle fixed to an upper edge of the hinged component, a spring-loaded handle bar arranged below the handle, the handle bar having two bent ends, a recess in the upper edge of the hinged component, and a groove in the base component, wherein one end of the handle bar is fixed to the upper edge of the hinged component and the other end engages in the groove in the base component through the recess in the upper edge of the hinged component, and wherein the one end of the handle bar is directly fixed to an exterior surface of the upper edge of the hinged component, such that all portions of the handle bar, except for a portion of the other end of the handle bar that engages in the groove through the recess, are positioned at an exterior of the hinged component.

2. The quick release fastener system according to claim 1, wherein the handle bar is a round spring wire.

3. The quick release fastener system according to claim 2, wherein the recess in the upper edge of the hinged component is a slot which is wider than a diameter of the spring wire.

4. The quick release fastener system according to claim 3, wherein the other end of the handle bar reaching through the recess is bent back U-shaped.

5. The quick release fastener system according to claim 2, wherein the groove is wider than a diameter of the spring wire.

6. The quick release fastener system according to claim 1, wherein the groove is arranged in an upper edge of the base component, which engages beneath the upper edge of the hinged component.

7. The quick release fastener system according to claim 1, wherein one edge of the groove includes an angular catch to retain the other end of the handle bar.

8. A hand-operated band saw housing, the housing comprising: a base tray having an upper edge, the upper edge having a groove, a hinged lid having an upper edge, the upper edge having a recess extending therethrough, a handle being fixed to the upper edge of the lid, a spring-loaded handle bar having two bent ends, the handle bar being arranged below the handle, wherein one end of the handle bar is fixed to the upper edge of the lid and the other end of the handle bar extends through the recess of the upper edge of the lid to engage in the groove of the base tray, such that the handle bar, the recess and the groove form a fastener for opening and closing of the housing.

9. The housing according to claim 8, wherein one edge of the groove includes an angular catch to retain the other end of the handle bar.

10. The housing according to claim 8, wherein the one end of the handle bar is directly fixed to an exterior surface of the upper edge of the lid, such that all portions of the handle bar, except for a portion of the other end of the handle bar that engages in the groove through the recess, are positioned at an exterior of the lid.

11. The housing according to claim 10, wherein the groove is provided in an exterior surface of the upper edge of the base tray and wherein when the housing is in a closed state, the exterior surface of the upper edge of the base tray directly faces and opposes an interior surface of the upper edge of the lid, such that the groove aligns with the recess.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The present invention will become more fully understood from the detailed description given hereinbelow and the accompanying drawings which are given by way of illustration only, and thus, are not limitive of the present invention, and wherein:

(2) FIG. 1 illustrates a slightly open band saw;

(3) FIG. 2 is a detailed view of the quick release fastener in an open state;

(4) FIG. 3 illustrates a cross section through the quick release fastener in the open state; and

(5) FIG. 4 illustrates a cross section through the quick release fastener in the closed state.

DETAILED DESCRIPTION

(6) FIG. 1 shows a slightly open band saw. The housing 1 has the base tray 2 and the swivel-mounted lid 3. The handle 4 is attached to the upper edge 10 of the lid 3. Underneath is the handle bar 5. The groove 6 is incorporated in the upper edge 11 of the base tray 2. The engagement of the second end 9 of the handle bar 5 in the groove 6 locks the housing 1.

(7) FIG. 2 shows a detailed view from FIG. 1. The handle bar 5 is positioned below the handle 4 on the upper edge 10 of the lid 3. The first end 8 of the handle bar 5 is mounted on the edge 10, for example, screwed in from below.

(8) The second end 9 of the handle bar 5 immerses with its U-shape in the slot 12.

(9) On the upper edge 11 of the base tray is the groove 6, opposite the slot 12. The angular catch 7 allows for the second end 9 of the handle bar 5 to slide into the groove 6.

(10) FIGS. 3 and 4 illustrate a cross section through the quick release fastener in the opened and in the closed state. The handle bar 5 is mounted at the upper edge 10 of the lid 3, which with its bent end 9 dips through the slot. When closing the housing, the bent end 9 slides over the angular catch 7 into the groove 6, which is located in the upper edge 11 of the base tray 2.

(11) The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are to be included within the scope of the following claims.
