1. Technical Field of the Invention
The present invention relates to a knife block, and particularly to a selectively tiltable knife block.
2. Description of the Related Art
Knife blocks are known for storing knives. Conventional knife blocks include a plurality of slots in which knife blades may be inserted. Knife handles typically extend from conventional knife blocks for ease in withdrawing the knives therefrom.
Despite there being numerous different knife blocks, a need exists for a knife block that efficiently and conveniently stores knives and includes a lock safety feature so that children cannot access the stored knives.
Embodiments of the present invention satisfy a significant need for a knife holder that efficiently holds knives when not in use and presents the stored knives from being easily withdrawn. According to an exemplary embodiment of the present invention, the knife holder includes a block member having at least one slot disposed along a top surface thereof for receiving a portion of a knife therein. The knife block may also include a housing member to which the block member is pivotally attached along a transverse pivot axis so that the block member may be moved between an upright position in which the top surface of the block member is positioned substantially within the housing and an extended position in which the top surface of the block member extends from the housing at a predetermined angle. When the knife block is in the upright position, knives cannot be easily withdrawn.
The knife block may further include a lock mechanism having an actuator coupled to the block member such that manipulating the actuator by finger applied pressure selectively locks the block member in the upright position. Because knives cannot be easily removed from the knife block when the block member is in the upright position, the lock mechanism advantageously prevents a child from accessing the stored knives.
The knife block may still further include an opening mechanism that provides for a smooth and controlled movement of the block member from the upright position to the extended position. The opening mechanism may include a latch member that is disengaged by moving the front of the block member slightly inwardly, relative to the housing. Thereafter, the block member is urged outwardly from the upright position by a hydraulic member until the block member is in the extended position. The block member may be subsequently returned to the upright position by urging the block member inwardly until the latch member engages the block member and holds the block member in the upright position.
A more complete understanding of the system and method of the present invention may be obtained by reference to the following Detailed Description when taken in conjunction with the accompanying Drawings wherein:
The present invention will now be described more fully hereinafter with reference to the accompanying drawings in which exemplary embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. Rather, the embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Referring to
Knife block 1 may further include a housing 7 to which block member 3 is pivotally attached. Housing 7 is sized and shaped to substantially house and/or contain block member 3 when block member is in an upright position in which stored knives are substantially vertical, and to allow top surface 3A of block member 3 to extend from housing 7 when block member 3 is in an extended position in which stored knives are positioned at an angle between the vertical and horizontal. Housing 7 may include a base 8, sides 9, a top or cover 10 and back 11.
Base 8 has a substantially flat lower surface. As shown in
Sides 9 of housing 7 may be connected to opposed sides of base 8. Back 11 may be connected between sides 9. Cover may be connected to sides 9 and back 11. Cover 10 may be sized so as to cover or otherwise be positioned substantially entirely over block member 3 when block member 3 is in the upright position. When in the upright position, block member 3 is contained within the inner area defined by base 8, cover 10, sides 9 and back 11. The clearance between cover 10 and the top of handles of knives stored in knife block 1 when block member 3 is in the upright position is such that stored knives cannot be withdrawn.
Base 8, cover 10, sides 9 and back 11 may be formed of a substantially rigid material, such as a metal composition. It is understood, however, that base 8, cover 10, sides 9 and back 11 may be constructed from rigid materials other than metal. It is further understood that some of base 8, cover 10, sides 9 and back 11 may be formed from one material and other of base 8, cover 10, sides 9 and back 11 may be formed from another material.
Housing 7 may include a weight member 13 (
As stated above, block member 3 is pivotally engaged with housing 7. Specifically, knife block 1 may include a pivot axle 14 which defines an axis about which block member 3 selectively rotates. The rotational axis formed by pivot axle 14 may be transverse to the exposed front surface of block member 3. In an exemplary embodiment of the present invention, pivot axle 14 is affixed to housing 7 and block member 3 freely rotates about pivot axle 14. In this way, block member 3 is capable of being tilted from the upright position to the extended position.
Knife block 3 may include a lock mechanism 30 to lock block member 3 in the upright position. As stated above, there is provided little clearance between the top 10 of housing 7 and the top of the handles of knives stored in knife block 1 when block member 3 is in the upright position, such that withdrawal of knives cannot occur. By providing a lock that maintains block member 3 in the upright position when activated, knife block 3 provides a child safety type of function.
With reference to
In an exemplary embodiment of the present invention, actuator 32 may be moved inwardly in order for post member(s) 34 to be aligned with slot(s) 36A. Further, lock mechanism 30 may include a spring member 38 disposed between plates 40 and in substantial coaxial alignment with pivot axle 14. One of the plates 40A may be affixed to pivot axle 14 and the other plate 40 may be affixed to housing 7. In this way, inward movement of actuator 32 causes plate 40A to be moved closer to plate 40B and spring member 38 to be compressed. When actuator 32 is no longer forced inwardly, spring member 38 expands which forces plate 40A away from plate 40B, which thereby forces actuator 32 outwardly.
As shown in
It is understood that additional anchoring of block member 3 may be included by anchoring block member 3 to the base 8 of housing 7. This additional anchoring would also be activated by manipulation of actuator 32.
Knife block 1 may further include an open/close mechanism for selectively latching block member 3 in the upright position and for selectively moving block member 3 from the upright position towards the extended position. In the exemplary embodiment of the present invention, the open/close mechanism may move block member 3 towards the extended position in a relatively slow, controlled manner.
Specifically, the open/close mechanism may include a spring-based latch unit 52 for selectively latching block member 3 to housing 7. Referring to
It is understood that the particular location of latch unit 52 (male latch member 54, female latch member 56 and spring latch member 58) may be located at positions along housing 7 and block member 3 other than the location depicted in FIG. 4. For instance, latch unit 52 may be disposed along an upper portion of housing 7 and block member 3 so that block member 3 may be coupled in the upright position near the top thereof.
The relationship between female latch member 56 and spring latch member 58 is such that female latch member 56 moves between the first and second positions upon consecutive instances of female latch member 56 being urged inwardly towards spring latch member 58, such as by male latch member 54. For instance, temporarily urging female latch member 56 towards spring latch member 58 may couple female latch member 56 thereto so that female latch member 56 may not be urged outwardly, by a spring 68 in spring latch member 58, beyond the second position. Subsequent temporary urging, such as by male latch member 54, of female latch member 56 towards spring latch member 58 may decouple female latch member 56 from spring latch member 58 so that the spring 68 in spring latch member 58 urges female latch member 56 towards the first position. The structural relationship between female latch member 56 and spring latch member 58 may be any of a number of different implementations, including: a conventional ink pen structure having a rotating sleeve for selectively moving the ink-dispensing point of the pen to and from an outward position for writing; a conventional cassette deck door structure for closing and opening the door of the cassette deck; etc.
Each prong of U-shaped pin member 66 traces corresponding channel 56B defined by cam member 56C as female latch member 56 is moved within spring latch member 58 in successive inward movements. In a first movement, a prong of U-shaped pin member 66 member may be forced to the top of cam member 56C at point 70, after which spring 68 forces female latch member 56 outwardly from spring latch member 58 so that the prong rests at point 72 along cam member 56C. This rest position represents the above-described second position in which the female latch member 56 grasps the male latch member 54. In a second, subsequent movement of female latch member 56, each prong of pin member 66 may be forced to a second top of cam member 56C at point 74, after which spring 68 forces female latch member 56 outwardly so that the prong rests in the channel at the base of cam member 56C. This rest position represents the above-described first position in which the female latch member 56 extends more outwardly from spring latch member 58 and no longer grasps the male latch member 54. By repeatingly urging female latch member 56 temporarily inwardly towards spring latch member 58 in this fashion, female latch member 56 alternatingly couples and decouples from male latch member 54, and thereby locks and unlocks block member 3 from housing 7, respectively.
Latch unit 52 may further include a hydraulic member 60 (
Movement of block member 3 relative to housing 7 moves piston rod 64 and the piston within sealed compartment 62, and thereby changes the fluid pressure therein. The fluid pressure in sealed compartment 62 is utilized to move block member 3 from the upright position to the extended position.
It is understood that knife block 1 may utilize other biasing mechanisms to bias or push block member 3 to the extended position. For instance, knife block 1 may utilize a spring member for biasing block member 3.
The use of knife block 1 will be described with reference to
At this point, block member 3 is maintained in the upright position and knives cannot be easily removed from knife block 1. Lock mechanism 30 may be optionally activated to lock block member 3 in the upright position, by urging actuator 32 inwardly while rotating actuator 32 until post member(s) 34 engages with slot(s) 36A of bracket 36. Actuator 32 is manipulated in this way by finger or hand applied pressure. Once post member(s) 34 is engaged with slot(s) 36A, the finger or hand applied pressure may be released from actuator 32. Block member 3 is now locked in the upright position.
To unlock block member 3 from the upright position, actuator 32 may be urged inwardly while rotating it in the opposite direction to disengage post member(s) 34 from slot(s) 36A. Block member 3 may be subsequently placed in the extended position by temporarily urging block member 3 slightly inwardly with hand or finger applied pressure so that upon release of the pressure, spring latch member 58 no longer maintains female latch member 56 in the second position. At this point, prongs of pin member 66 are moved from point 72 to point 74 and then to the base of cam member 56C corresponding to the first position (
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 intended to be included within the scope of the following claims.
