Description




BACKGROUND OF THE INVENTION




1. Field of Invention




The invention relates to knife holders, such as knife holding blocks that hold a plurality of knives, and in particular to knife holders that prevent the sharpened edges of the knife blades from becoming dull.




2. Description of Related Art




Knife holders for holding a plurality of knives, typically in the form of plastic or wooden blocks having a plurality of slots, are well known. The typical construction of these knife holders results in the knife blades being oriented vertically with the sharpened edge of each blade facing downward. In these typical knife holders, only the blades of the knives are inserted into the block. Therefore, the blades support the knives, and in particular, the sharpened edges of the blades contact the lower portion of the knife-holding slots in order to support the knives in the knife block. This causes the sharpened edges to become dull over the course of time.




SUMMARY OF THE INVENTION




It is one aspect of the invention to provide an arrangement in which a knife holder holds a plurality of knives without causing the sharpened edges of the knives from becoming dull. In accordance with this aspect of the invention, the knives are supported in a manner such that the sharpened edges of the knife blades do not contact the knife-holding slots in the knife holding block.




In accordance with a preferred embodiment, the invention relates to a knife set that includes a knife block having a plurality of knife-receiving slots, and a plurality of knives, corresponding in number to the plurality of knife-receiving slots. Each of the knives has a handle and a blade, with each blade having a sharpened edge. At least one of the knives, and a corresponding at least one of the knife-receiving slots, includes engaging structures that support the at least one knife in the corresponding at least one slot so that the sharpened edge is suspended within the slot out of contact with any portion of the knife block.




In a preferred embodiment, the handle of the knife includes an elongated protrusions on each side of the front portion of the handle that is located adjacent to the blade. The knife-receiving slots include enlarged (preferably tapered) openings into which the front portion of the knife handle is inserted. The openings include grooves that correspond to the elongated protrusions on the sides of the handle. This results in the handle being held by the knife block, with the blade suspended out of contact with the slot. Accordingly, the knife handle, rather than the blade, supports the knife in the block. Therefore, the blade does not become dull because the sharpened edge of the blade does not contact the slot.




The main object of the invention can be obtained numerous ways. For example, the above-described protrusions can be provided in the slot openings, and the grooves can be provided in the knife handle (or in the knife blade). In addition, the knife handle can support the knife in the block without providing protrusions/grooves in the front portion of the knife and in the slot opening. Furthermore, it is possible to provide a protrusion or groove on the knife blade, rather than on the handle, which then engages with a corresponding groove/protrusion in the slot. With this alternative, it is not necessary for the front portion of the knife handle to be inserted into the knife block.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS




The invention now will be described with reference to exemplary preferred embodiments. The invention can be used with various types of knife holders including, for example, (1) stationery knife holding blocks that are placed on countertops, as well as with (2) slidable knife holders in which the knife holding block is slidably mounted, for example, beneath cabinets, under countertops, etc. Such slidable knife holders are disclosed in U.S. Pat. No. 5,655,672 to the present inventor. The disclosure of U.S. Pat. No. 5,655,672 is incorporated herein by references in its entirety. In addition, and as will be described in more detailed below, the knife holder (i.e., the knife block) can include a locking mechanism that permits the knives to be locked within the knife holding block. Such locking mechanisms are disclosed in the present inventor's U.S. Pat. No. 6,375,016B1. The disclosure of U.S. Pat. No. 6,375,016B1 is incorporated herein by reference in its entirety.




As shown in

FIG. 2

, a knife set


10


includes a knife holding block


20


and a plurality of knives


40


.

FIG. 1

shows the knife holding block


20


without any knives inserted therein.




As shown in

FIG. 2

, the knife holding block


20


includes a plurality of knife-receiving slots


22


. Each slot


22


receives a knife therein. Each of the slots includes an enlarged opening


26


into which a front portion of the corresponding knife


40


is inserted. In addition, each side of the enlarged openings


26


includes a groove


28


. Each groove will receive an elongated protrusion, to be described below, provided on each side of the front portion of the handles of the knives


40


.





FIG. 3

is a plan view of a knife block having six knife-receiving slots


22


therein. The structure of the slots is similar to what is provided in the knife block


20


of

FIGS. 1 and 2

. Each of the enlarged openings


26


is tapered such that the opening has its largest area at the surface of the block, and then tapers so as to have a smaller area adjacent to the blade-receiving slot


22


. Each side of the tapered opening has a groove


28


.





FIGS. 4 and 5

are side and front views, respectively, of a knife that is usable with the knife block of

FIGS. 1-3

. The knife


40


includes a handle


42


and a blade


44


. The blade


44


includes a sharpened edge


46


. The front portion


45


of the handle


42


is insertable into the enlarged opening


26


of the corresponding slot


22


in the knife block


20


. Like the enlarged openings


26


, the front portion


45


of the handle


42


is tapered so as to mate with the enlarged opening


26


. Thus, and as shown in

FIG. 5

, the thickness of the front portion


45


increases as one moves from the blade


44


toward the gripping portion of the handle


42


. In addition, each side of the front portion


45


of the handle


42


includes an elongated protrusion


47


. Each elongated protrusion mates with a corresponding groove


28


provided in the enlarged opening


26


of the knife-receiving slot


22


.




Accordingly, when the knife is completely inserted into the knife slot


22


, the tapered, front portion


45


of the knife will be inserted into the enlarged opening


26


. At this time, the elongated protrusions


47


will engage with the grooves


28


. The knife will be supported by the engagement between the protrusions


47


and the grooves


48


. Thus, the knife will be supported in the knife block


20


by the handle


42


, rather than by the blade


44


. By appropriately dimensioning the slot, the sharpened edge


46


of the blade will be suspended within the slot so that it does not contact any portion of the slot when the protrusions


47


and grooves


28


are engaged with each other.




It is, of course, possible to provide the protrusions in the enlarged opening


26


of the knife-holding slots, and to provide corresponding grooves in the front portion


45


of the knives


40


. Such an arrangement is shown in

FIGS. 7A and 7B

. In particular,

FIG. 7A

shows the elongated protrusions


29


in the enlarged opening


26


of the knife-receiving slot


22


.

FIG. 7B

shows a knife having grooves


49


provided in each side of the front portion


45


of the handle


42


.




It is also possible to provide a locking mechanism by which the knives are locked within the knife holder. Such an arrangement is shown in FIG.


6


. The basic structure is similar to what is described in the inventor's above-noted related U.S. Pat. No. 6,375,016B1, except that the locking mechanism engages the knife handle which is inserted into the knife block), rather than engaging the blade. In addition, the locking mechanism engages with a lower portion of the knife, rather than the upper portion of the knife as described in the related application. As shown in

FIG. 6

, the block


20


includes a vertically extending passage


50


in which a locking member


55


moves. As shown by arrow


57


, the locking member


55


moves up and down. The locking member can be spring biased in the upward direction so that it will be inserted into a notch


43


provided in the lower portion of the front part


45


of the handle in order to lock the knife


40


within the knife holder block


20


. It is advantageous to provide the notch in the knife handle, rather than in the knife blade because it enables standard knife blades to be used. It is, of course, possible to have the locking member engage the upper portion of the handle, or to have the locking member engage the blade (from above or below). The remainder of the knife structure and the knife-receiving slot structure can be the same as described above with respect to

FIGS. 1-5

,


7


A and


7


B.




The invention is not limited to the illustrated embodiments. The engaging structure, which is the structure that supports the knife within the knife block, can be elements other than a protrusion and a groove. In addition, and as noted earlier, when elements such as protrusions/grooves are used, such elements can be provided on either the knife handle or the knife blade (as well as within the knife-holding slot). The engaging structures can be the enlarged opening of the knife-holding slot and the corresponding front portion of the knife handle (i.e., it is not necessary to provide additional elements such as protrusions/grooves). The enlarged opening (if provided) and the corresponding front portion of the knife handle need not be tapered. However, the tapered structure is preferable because it is easier to insert such knives into the knife holder, and also is more aesthetically pleasing.




It is not necessary for all of the knife-receiving slots in the knife block to include the engaging structure of the invention. For example, it may be desirable to provide the engaging structure only on knives that are not serrated. In addition, if the knife block includes slots that are not intended to receive knives (for example, it is common to provide slots that hold scissors or a sharpening tool), it is not necessary to include the engaging structure for such slots.




While the present invention has been described with reference to preferred embodiments thereof, it is to be understood that the invention is not limited to the preferred embodiments or constructions. To the contrary, the invention is intended to cover various modifications and equivalent arrangements. In addition, while the various elements of the preferred embodiments are shown in various combinations and configurations, which are exemplary, other combinations and configurations, including more, less or only a single element, are also within the spirit and scope of the invention.
