Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a knife block to hold a plurality of cooking knives and a file to grind such cooking knives (hereinafter referred to only as knives).




2. Prior Art




Kitchens of houses or restaurants are provided with knives for cooking.




In some cases, the kitchen knife housing may be found inside the partition door under the kitchen scullery. In other cases, a plurality of knives are housed in a kitchen drawer. In any case, the knives are taken out when they are demanded for cooking.




However, it can be inconvenient to access knives. For instance, when quick cooking is demanded, it is not easy to take out knives from inside of the partition door. In particular, in the case when several different kinds of knives are desired when cooking, it is an annoyance to take out the knives from, or put them back, to inside of the partition door after washing the knives with water and wiping them off. For this reason, most people lay the knives temporarily on the scullery after they use the knives. Knives placed on the scullery are very dangerous and unsanitary. The present invention has been made with the foregoing background in mind. The aim of the present invention is to offer a knife block of a simple structure and yet convenient for handling knives.




SUMMARY OF THE INVENTION




The present invention offers a knife block comprising a plurality of knife guides provided with slots through which each knife is inserted downward, respectively. Each slot is provided with narrow gap to guide the knife to slide properly vertically downward. The knife block of the present invention further comprises a cylindrical cover plate made of stainless steel surrounding the inserted knives. There is a lid on the upper end of the cylindrical cover. The lid is provided with a plurality of slots. Said cylindrical cover stands in an upward direction with a predetermined pertinent inclination.

. The blade guide


12


A, as shown in

FIGS. 4A and 4B

, presents a form of vertically divided guide body


12




b


and each of the two divided guide body


12




b


is integrated together through the left and right circumferential edges


12




c,




12




d.


For this reason, the guide body


12




b


has a clearance SP through which the blade part C


1


of the knives C is inserted.




The guide body


12




b


is made of plastic and offers plasticity. It retains the blade part C


1


of the knives C inserted into such clearance SP. One circumferential edge


12




d


is formed thicker comparing with the thickness of the other circumferential edge


12




c.


The blade part C


1


slidably connects with respect to the circumferential edge


12




d.


There is provided with a protrusion


12




e


at the lower end of the circumferential edge


12

1


quite easily.




A flange-like engagement part


12




a


is formed on the aperture side of the guide body


12




b.


There is provided a flat tapered plate


12




i


at one side of the guide body


12




b.


The other side of the guide body


12




b


is also provided with the other flat tapered plate


12




i.


FIG.


2


and

FIG. 4

indicate one of the surfaces of the guide body


12




b.


The flat tapered plate


12




i


and


12




i


are formed tapered in upright direction and gradually expanded toward the blade guide


12


A. One slit


12




f


is formed between the tapered part


12




i


and the circumferential edge


12




c.


The other slit


12




f


is formed between the flat tapered plate


12




i


and the circumferential edge


12




d.


Upper end parts


12




g


are formed on the upper end of the flat tapered plates


12




i.


(FIG.


2


and

FIG. 4

show one face only.) There is predetermined distance L between the upper end parts


12




g,


and the engagement part


12




a


(refer to FIG.


4


A).




The blade guide


12


A is, as shown in

FIG. 2

, fitted into the insert hole


15


A, and the engagement part


12




a


of said blade guide


12


A is engaged with the cap part


11


. Meanwhile, the lower end of the blade guide


12


A is fitted into the support hole


14


of the support plate


13


. The support hole


14


interferes with the flat tapered plates


12




i


gradually expanding upwardly. Then, each of the flat tapered plates


12




i


moves toward the direction to reduce the clearance SP due to actuation of slits


12




f


and the support hole


14


goes up further. When the support hole


14


goes over beyond the upper end parts


12




g,


the flat tapered plates


12




i


are released interference by the support hole


14


and expands due to elastic action of the guide body


12




b.


A position of the support plate


13


when the support hole


14


goes over the upper end parts


12




g


is indicated by the imaginary line in

FIG. 4C

(hereinafter the position is referred to as a preparation position).




The circumference of the support plate


13


is folded downwardly and forms a connecting part


13




a.


In short, when the support plate


13


is housed within the cover part


20


, the connecting part


13




a


slides the inner surface to lead the support plate


13


to move (refer to FIG.


4


C). For this reason, stability of the support plate


13


is improved. The support plate


13


is prevented from being inclined in the cover part


20


.




A bolt


16


passes through the support plate


13


. When the blade guide


12


A is reached to said preparation position, the bolt is screwed in. The tip end of the bolt


16


connects the inner surface of the cap part


11


and the support plate


13


is pressed downward. The support plate


13


is reached to the upper end parts


12




g.




12




g


of the blade guide


12


A (refer to the actual line in FIG.


4


A). The support plate


13


is engaged with the upper end parts


12




g


and supported. The thickness of the cap part


11


is larger than the thickness of the cover part


20


. The cap part


11


is endurable against the pressed bolt


16


.





FIG. 5

indicates inner state of the cover part


20


. It is a cross sectional view of the knife block along the Z—Z line indicated in FIG.


1


. The support plate


13


is held in the cover part


20


to form a space


17


. In short, the inside surface of the cover part


20


and outside part of the support plate


13




a


are not touched throughout the circumference, but the support plate


13


presents space between the cover plate


20


at both of its sides along the longitudinal direction and thus a space


17


is generated. Accordingly, when the inside of the cover part


20


is washed, water existing between the support plate and the cap part


11


is drained off smoothly (refer to FIG.


5


).




As mentioned above, the holder part


10


with respect to the embodiment of the present invention comprises the cap part


11


, a plurality of the blade guides


12


A, the support plate


13


, and bolts


16


.




The lower aperture of the cover part


20


is detachably fixed to the base plate


30


. The structure thereof is explained with the accompanied drawings

FIG. 2

, FIG.


6


A and FIG.


6


B.

FIG. 6A

indicates a perspective view of the lower aperture


21


of the cover part


20


.

FIG. 6B

is a cross section along the W—W line in FIG.


6


A. The lower part of the cover part


20


is sliced off with an inclination with respect to the center line CL of the cylinder (refer to FIG.


6


B). The sliced surface forms the lower aperture


21


.




Meanwhile, there is formed a recessed part


31


on the base plate


30


made of hard rubber or rubber like material. The configuration of a circumferential side wall


31




a


(refer to

FIG. 2

) on the base plate


30


corresponds to the configuration of the lower aperture


21


of the cover part


20


. Thus, the lower aperture


21


of the cover part


20


is relatively and fixedly fitted to the circumferential side wall


31




a


from the inclined direction. Due to such configuration, the lower aperture


21


is placed horizontally with respect to the surface of the base plate


30


. An acute angle part


21




a


of the lower aperture is engaged with the circumferential side wall


31




a


of the recessed part


31


of the base plate


30


. Now the cover part


20


stands with an inclination but it stands stably. As the base plate


30


is made of hard rubber or rubber like material, the cover part


20


is always held stably due to elastic power of the material of the base plate


30


. It is also easy to take out the cover part


20


from the circumferential side wall


31




a


of the base plate


30


.




There are formed protrusions


21




b


around the circumferential edge of the lower aperture


21


. The three protrusions


21




b


are intended to set the cover part


20


stably on the base plate


30


. It is thus required to provide said three protrusions at a position to connect them at least with a triangle configuration (refer to a dot line in FIG.


6


A). In particular, when configuration of the cross section of the cover part


20


presents an ellipse configuration, one protrusion


21




b


is placed on one end of the longitudinal axis and other two protrusions


21




b


are provided at contrast positions on the circumferential edge of the lower aperture


21


with respect to the center line of the longitudinal axis of the lower aperture. It goes without saying that the configuration of the lower aperture


21


of the cover part


20


not strictly limited to a fixed ellipse configuration but other configuration such as Japanese straw shoes or cocoon are also included.




One end of said longitudinal axis of the lower aperture


21


indicates an acute angle part


21




a.


However, in the embodiment of the present invention, the other end of said longitudinal axis indicates an obtuse angle side part


21




c


as shown with two dots line in FIG.


6


B.




The cover part


20


is surrounded with stainless steel plate and is welded two edges together. In the preferred embodiment of the present invention the edge to be welded is the other end of the longitudinal axis of the cover part


20


. Welding is performed along the edges of the cover plate starting from the obtuse angle side part


21




c


of the lower aperture


21


. When welding is performed it is required to finish the welded parts with preferable finishing treatment such as grinding or the like. If the obtuse angle side part


21




c


should not be formed, a recess is appeared at the starting position of the welding and it becomes impossible to repair the cover part


20


afterward. Formation of the obtuse angle side part


21




c


is thus desired to conceal such a recess in finishing treatment.




Next, a method to assemble the knife block


1


according to the present invention and the effect thereof are explained with the accompanied drawings

FIG. 1

, FIG.


2


and FIG.


4

When the support plate


13


is placed on the preparation point, bolts


16


are tightened. The clearance between the support plate


13


and the cap part


11


is expanded and an engagement part


12




a


of the blade guide


12


A is engaged with the cap part


11


. The upper end parts


12




g


are assembled to the support plate


13


. The holder part


10


is completely fixed to the upper aperture of the cover part


20


.




Next, fix the lower aperture


21


of the cover part


20


into the recess part


31


of the base plate


30


. The cover part


20


stands upright with a predetermined pertinent inclination. The knife block is thus completed. When the knife block


1


is practically used, the base plate


10


is placed on a table. As indicated in

FIG. 1

, the cap part


11


stands upright with a predetermined pertinent inclination to use said knife block


1


. The knives C are retained in the holder part


10


in the cap part

12


A and trembling defect in leftward and rightward direction is prevented. Meanwhile, as inserting the blade part C


1


a grip part C


2


is engaged with the cap part


11


and stopped. In other words, the grip part C


2


of the knives C is engaged with the cap part


11


. In short, the grip part C


2


of the knives C is engaged with the cap part


11


and it is placed between the blade guides


12


A. The knives C retained as such are easily taken out when it is demanded. No drawers and no opening gate under the scullery is required. It is quite convenient to treat cooking materials.




When washing the knife block


1


, it is easy to wash the cover part


20


taking out the knives C from the knife block


1


because the cover part


20


and the base plate
