Abstract

The present invention relates to a device for containing one or more blades. In a preferred for, the device is a knife block for containing a plurality of knives. The device includes a housing having a plurality of openings, each opening for containing a respective blade therein. The device also includes a blade restraining mechanism including a restraining member having active and inactive conditions in that when a blade is inserted within one of the openings such that substantially an entire cutting edge of the blade is within the opening, in the active condition the restraining member prevents withdrawal of the blade from the opening and in the inactive condition the restraining member allows withdrawal of the blade from the opening. In a preferred form, the device is configured to contain a plurality of blades that each include opposite substantially parallel sides which meet at a cutting edge, an opening within the blade extending between and transversely to the substantially parallel sides of the blade and enclosed within the blade, wherein the opening is engaged by the restraining member when in the active position to prevent withdrawal of the blade from the opening and which is disengaged by the restraining member when in the inactive position to allow withdrawal of the blade from the opening. The present invention also relates to a combination of the device and one or more of the blades.

Claims

1. A device for containing one or more blades, the device including:

a housing having a plurality of openings, each opening of the housing for containing a respective blade therein;

a blade restraining mechanism including a restraining member having active and inactive conditions in that when a blade is inserted within one of the openings of the housing such that substantially an entire cutting edge of the blade is within the opening of the housing, in the active condition the restraining member prevents withdrawal of the blade from the opening of the housing and in the inactive condition the restraining member allows withdrawal of the blade from the opening of the housing;

wherein the restraining member is operable for engaging an opening within the blade when in the active position to prevent withdrawal of the blade from the opening of the housing and for disengaging the opening within the blade when in the inactive position to allow withdrawal of the blade from the opening of the housing.

2. The device for containing one or more blades as defined in claim 1, wherein the blade restraining mechanism includes one or more restraining members, wherein each restraining member is associated with one or more of the openings of the housing.

3. The device for containing one or more blades as defined in claim 1, wherein the blade restraining mechanism includes a blade release mechanism that is operable for causing the one or more restraining members to change from the active condition to the inactive condition.

4. The device for containing one or more blades as defined in claim 3, wherein the blade release mechanism is operable for causing each of the one or more restraining members to change from the active condition to the inactive condition.

5. The device for containing one or more blades as defined in claim 3, wherein the blade release mechanism includes a manual release mechanism including at least two stages of movement.

6. The device for containing one or more blades as defined in claim 5, wherein a first one of the stages involves manually moving a manually operable release member in a first direction and the second stage involves manually moving the manually operable release member in a second direction.

7. The device for containing one or more blades as defined in claim 6, wherein the first direction is transverse to the second direction.

8. The device for containing one or more blades as defined in claim 6, wherein the first direction of movement involves linear translation of the manually operable release member along an axis and the second direction of movement involves rotation of the manually operable release member about the axis.

9. The device for containing one or more blades as defined in claim 6, wherein the blade release mechanism includes a third stage of movement.

10. The device for containing one or more blades as defined in claim 1, the blade restraining mechanism includes one restraining member in the form of an elongated blade engaging member that is positionable adjacent the openings of the housing and extending substantially perpendicular to opposite parallel sides of the blade when the blade is inserted within the opening of the housing, the elongated blade engaging member being movable between a position in which when substantially the entire cutting edge of the blade is within the opening of the housing the elongated blade engaging member engages the blade and prevents withdrawal of the blade and a position in which when substantially the entire cutting edge of the blade is within the opening of the housing the elongated blade engaging member is out of engagement with the blade and allows withdrawal of the blade.

11. The device for containing one or more blades as defined in claim 10, the elongated blade engaging member includes a rod that is receivable within the opening within the blade.

12. The device for containing one or more blades as defined in claim 11, the housing includes an aperture that is aligned with the direction of the opening within the blade when the blade is inserted within the opening of the housing, the aperture receives the rod therethrough when the blade restraining member is in the active condition.

13. The device of claim 1, wherein the device is a knife block.

14. The device of claim 1, further including a blade sharpener for sharpening the cutting edge of the blade.

15. In combination a blade and a device for containing one or more of the blades including the device of claim 1.

16. The combination of claim 15, wherein the blade includes opposite substantially parallel sides which meet at a cutting edge, the opening within the blade extends between and transversely to the substantially parallel sides of the blade and is enclosed within the blade, wherein the opening within the blade is engaged by the restraining member when in the active position to prevent withdrawal of the blade from the opening of the housing and which is disengaged by the restraining member when in the inactive position to allow withdrawal of the blade from the opening of the housing.

17. The combination of claim 15, wherein the opening within the blade is in the form of a substantially round hole extending through the blade between the opposite parallel sides of the blade.

18. A blade configured for use with the device for containing one or more blades of claim 1, the blade including a handle and opposite substantially parallel sides extending from the handle which meet at a cutting edge, an opening within the blade extending transversely to the parallel sides and positioned adjacent to the handle.

19. The blade of claim 18, wherein the opening within the blade is in the form of a substantially round hole extending through the blade between the opposite parallel sides of the blade.
