QUICK RELEASE FASTENER FOR A BAND SAW

Abstract

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

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

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

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

5. The quick release fastener according to claim 1, wherein the groove is arranged in an upper edge of the base tray, which engages beneath the upper edge of the lid.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0020] 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:

[0021] FIG. 1 illustrates a slightly open band saw;

[0022] FIG. 2 is a detailed view of the quick release fastener in an open state;

[0023] FIG. 3 illustrates a cross section through the quick release fastener in the open state; and

[0024] FIG. 4 illustrates a cross section through the quick release fastener in the closed state.

DETAILED DESCRIPTION

[0025] 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.

[0026] 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.

[0027] The second end 9 of the handle bar 5 immerses with its U-shape in the slot 12.

[0028] 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.

[0029] 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 12 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 5.

[0030] 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.
