Description

This invention relates to a hand and blade protection device for tools having a cover fitted between the handle and a working member such as a knife blade which can be pivoted into a sheath covering the working member on the one hand and into a guard holding the tool in the working position on the other.

Ordinary blade tools such as a knife, file, etc. do not have any protection for the hand holding the hand when using the tool from the handle. The hand can be easily scratched or otherwise damaged when performing a work movement and when touching and scratching a workpiece or other nearby object. The blade, on the other hand, has loose sheaths or the like. However, the sheath can drown, after which even the most delicate blade is easily exposed to knocks.

However, the cutting edge of the blade is protected in link-15 knives, in which the blade is turned inside a handle or a housing acting as a handle, such as in U.S. Pat. No. 4,707,920. Such devices do not have any cover that protects the hand from the outside on the outside in the working position.

In ordinary very sharp knives, it has been proposed to use as an accessory a cleatable detachable hand guard on the side of the handle between its ends as disclosed in U.S. Patent No. 3,538,605. However, the guard does not protect the hand from more than one side and does not protect the blades at all. As a loose piece, the cover is easily exposed to waste.

In order to avoid the above-mentioned disadvantages, the present invention provides an apparatus by which the above-mentioned disadvantages are avoided or at least considerably alleviated. The invention essentially comprises having a cover arranged between the handle and the working member, such as a knife blade, which can be turned on the one hand to cover the sheath covering the working element and on the other hand to protect the hand holding the tool in the working position. Such a device cannot be drowned without the loss of the entire tool 2 80224. In addition, it is easy to handle and can be quickly moved to a hand-protecting position.

The invention is known from those features which are further defined in the claims. The device according to the invention 5 has a strip or two arranged between the handle and the working member, such as a knife blade, which as flexible members can be fitted along the length of the blade to its sides and adhered to each other so as to form a blade shield, which prevents damage to the environment or handler. . Again, the gripped strips can be quickly detached from each other and pivoted back toward the handle, connecting them at their blade tip ends to each other and to the back of the handle, forming a loop or loop on the opposite side of the handle between the handle and the strip. . In this position, the strips protect the hand from scratches from the side and always the better the wider the strips. The length of the strips 20 is suitably such that they form two sides of the loose arc of the handle, allowing the hand to settle freely around the handle. In some cases, it may be advantageous to tighten the handle so as to strengthen the grip of the hand around the handle or handle. The tightness of the strip in this position can also be adjusted to have several mounting holes along its length so that the tension of the strip at its attachment point at the base of the blade and the rear end of the handle can be adjusted, locking the strips to a pin or similar from a suitable strip hole.

. The strips are preferably provided with elongate protrusions at their longitudinal edges so that as they come around the blade, the protrusions face each other and the protrusions in the second 35 enter the recess or recesses of the opposite protrusion so that they adhere to each other.

3 80224 Such bumps may continue along the entire length of the strips or they may also be intermittent. Near each end of the strips, they are preferably omitted to improve the flexibility of the strips. Abutment surfaces of the strips may be va-5 rustaa also the protrusions in addition to or in place of the label with a surface containing a per se known manner a number of small pin-like elevations between which the other party in similar or almost similar projections have .vastakkaiset and lock the parts together. In the sheath position 10, the free ends of the strips are suitably attached to each other so that the second part is made into a narrow projection tapering towards the end, which can be threaded into the locking hole of the second strip, which serves to attach the strip to the rear end of the handle.

To illustrate the invention, reference is made to the accompanying drawings, which show an example of an embodiment according to the invention, Figures 1 and 2 showing the device in a blade-protecting and a hand-protecting position, respectively, in a perspective view. Fig. 3 schematically shows the same device in the sheath position seen from the side and Fig. 4 the same device seen from the back of the blade.

Fig. 5 shows the device according to Figs. 3 and 4 turned to the hand-protecting position. Figure 6 shows on a larger scale the section A-A of Figure 3.

23 The exemplary knife has a handle 1 and a * t blade 2. At their junction 11 are attached strips 3 and 4 of flexible material such as plastic, leather or metal. These have reinforcements 6, 7, 8 and 9, whereby the reinforcement or protrusion 6 has an elongate the groove and the protrusion 30 corresponding to it in the mating part 7 and the corresponding parts in the reverse order. in the strip · 4, the lower edge protrusion 9 having a groove and in the supporting part 3 of the strip 3 a protrusion 8 which remains pressed with a suitable tightness. When pressed against each other, these parts hold the strips together 33 and form a sheath 2 on the blade.

When detached from each other, the strips 3 and A and at their ends turned behind the handle and threaded into the pin 5 of the handle from the hole 13 form a cover around the handle on each side of the handle. The pin 5 is suitably flat, as is the corresponding hole in the strips, whereby the locking can be performed by turning the pin 5, for example for 90 years, whereby its T-shaped branch keeps the strips in place. The second strip may have a transverse protrusion ^ 10 which closes the outer end of the sheath. The outer end of the second strip 10 may be sharpened, as in the strip 3, but not shown, so that the sharp end can be inserted into the hole 13 of the sheath 3, thus enhancing the stability of the strips in each other in the sheath position.

It is clear that the invention is not limited to the embodiment described above, but that many other structures can be presented within the scope of the following claims.
