FINGER GUARD FOR KNIVES Filed Sept. 11, 1958 Michael J. Zu/Io INVENTOR.
United States Patent Ofifice 2,901,824"- Patented Sept. 1, 1959- FlNGER GUARD FOR KNIVES MichaelJ. Znllo, Chicago, Ill. Application September 11, 1958, Serial No. 760,409 4 Claims. c1. 30 295 This invention relates to a safety device and more particularly to a fingerguard for a knife.
An object of the invention is to provide a device for protecting or safeguarding a persons finger or fingers when using a knife that has the corner of the blade protruding beyond the beginning of the handle. The invention is especially useful when a persons hands are wet or otherwise lubricated, for instance when slicing ham.
A further object of the invention is to provide a quickly applied and easily attached and detached guard for a knife to protect the fingers of the user of the knife.
These together with other objects and advantages which will subsequently become apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawing forming a part hereof, wherein like numerals refer to like parts throughout, and in which:
Figure 1 is a perspective view of a typical knife with one of the guards thereon.
Figure 2 is a sectional view taken on the line 22 of Figure 1.
Figure 3 is a sectional view taken on the line 33 of Figure 2.
Figure 4 is an exploded perspective view of in Figure 1.
Figure 5 is a perspective view of a modification of the guard.
In the accompanying drawings there is a conventional knife having a handle 12 and a blade 14. The blade 14 has a corner 16 which protrudes downwardly beyond the lower edge of handle 12 when the knife is in the orientation of Figure l. The corner 16 protrudes laterally outwardly from the handle 12 and often nicks or cuts the finger or fingers of the user or the knife, especially when the hands are lubricated. Guard 20 is adapted to be placed on the knife in order to protect the fingers of the knife user. In order to be practical and commercially salable, the guard has to be simple, easy to apply and must serve its intended purpose. Therefore, only two parts are in the construction. There is guard plate 22 and a bolt 24. The guard plate has a flat part 26 with a slot 28 which opens through one edge of this part. Two small sleeves 30 and 32 in alignment with each other are at the same edge of the part of plate 22 through which slot 28 opens. The slot is between the sleeves, spacing them sufficiently so that the blade 14 of the knife may pass therebetween. Bolt 24 is adapted to be inserted in the sleeves and be fastened in place by threading into sleeve 30. Therefore, a part of the bolt extends across slot 28 and is used to lock the guard in place on the knife.
Plate 22 has an angular part 36 at the edge of part 26 opposite to the edge that has sleeves 30 and 32. The angular part is approximately at right angles (Figure 2) and has a downturned part 38 at its edge and a smoothly curved tab 40 at its outer edge. This forms a stepped arrangement which provides ample protection for the user of the knife preventing (the hand from slipping and the guard becoming cut by the blade of the knife when the knife is in normal use.
As indicated previously, the cutting usually occurs at the corner 16 of the blade.
The guard 20a of Figure 5 is practically identical to the embodiment of Figure 1. The guard plate 22a has parts 26a, 36a, 38a and 40a which respond directly to the corresponding parts of guard 20. However, guard 2011 has no screw, nor does it have sleeves to accom modate the screw. In place of it, there is a single spring 24a attached, forinstance by having the ends fitted in apertures 44 and 46 in part 26a, to the guard plate 22a. The spring 24a extends over the outer end of the slot 28a and is adapted to extend over the handle 12 of a typical knife 10. When attaching the guard 20 to the knife, screw or bolt 24 is removed and the blade of the knife is slipped into the slot 28. When the guard occupies a plate on the blade of the knife against the front end of handle 12, the screw 24 is replaced. Accordingly, the guard is now very securely attached to the knife and in the proper position.
When applying guard 20a to the knife, the procedure is slightly simpler. The knife blade is merely slid through slot 28a with the spring stretching slightly over the blade at its junction with the handle. The spring tension holds the guard fastened on the knife.
In use, the guards fit all or almost all blades with a protruding corner regardless of the type of knife or knife handle. Further, the guards 2t} and 23a function as a stand for the knife when a person does not wish to lay the knife flat on its side.
The guard is used as such, having a mechanical movement on the knife. When a persons finger hits a palt of the guard, for instance part 38 or part 38a, the guard is sent forward against the corner 16 of the blade and at the same time oscillating flat parts 26 and 26a against the inner end of the knife handle. Accordingly, there is a certain amount of rocking movement between the guard and knife [to achieve the optimum performance.
The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to: limit the invention to the exact construction and operation shown and de scribed, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
What is claimed as new is as follows:
1. An attachment for a knife that has a blade and a handle with a corner of the blade protruding laterally outwardly from the handle at least at the junction of the handle with the blade, said attachment comprising a guard provided with a guard plate having a flat part abutting the forward end of the handle and provided with a slot through which the blade extends, an angular part lying under a portion of the handle adjacent to the blade corner, a downturned part at the rear edge of said angular part and located directly behind said corner of the blade providing a finger protector, and means attached to said guard plate on opposite sides of said slot and extending across said slot and the upper edge of said blade for holding said plate fastened to said knife with said plate occupying a position between said corner of said blade and said handle.
2. The attachment of claim 1 wherein said means comprise a bolt, said plate having a pair of sleeves spaced from each othere and in axial alignment with the space between said sleeves being in alignment with said slot, and said bolt carried by said sleeves and when attached to said sleeves having a portion thereof extenda ing across said slot in said space between said sleeves thereby closing one end of said slot.
3. An attachment for a knife that has a blade and a handle with a part of the bladmprotruding laterally outwardly from the handle at least at the,junction of thehandle with theblade, said, attachment,comprising a guard having a guard plate provided with a slot through which'the blade extends, and means connected with, said plate for. holding said plate fastened to saidaknife with said plate occupying a position between said part of said blade and said handle, said means comprising a spring having ends attached to said plate on opposite sides of said slot and adapted to be stretched over s aid knife andretain the plate fastened thereto.
'4. An attachment for a knife that has a blade and a handle lwithaparrt of the blade-protruding laterally outwardly from the handle at least at the junction of the;handle with the 'blade, said attachment comprising a guard having a *guard plate provided with a slot through which the blade extends, and means connected with said plate for holding said plate fastened to said knife and said plate occupying a position between said part of said blade and said handle, said means comprising a spring having ends attached to said plate on opposite sides of said slot and adapted .to be stretched over said knife and retain the platefastened thereto, said plate having parts inapproxirnately stepped formation which are located between the corner ,of the blade nearest to said handle and which protrude laterally from the handle.
