DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a pocket knife as defined in the preamble of claims 1 and 2. More particularly, the present invention relates to a pocket knife with a key blank or key similar to a key that can be secured to such a knife.

[0002]

BACKGROUND OF THE INVENTION Generally, multifunctional knives, such as "Swiss knives", pivot one between two sides of the knife.
Consisting of one or more cutting blades and / or one or more tools. Such a knife is an international patent application
Known from WO 95/26859, the knife is provided at one end with a ring which allows the attachment of one or more keys. Such a knife is not very practical to carry in a pocket as the key increases the volume of the knife. In addition, operation of the knife tool or cutting blade can be hindered by the key.

[0003] US Patent No. 5,392,622 discloses a pocket knife consisting of a number of tools, including a key, pivoting between the sides of the knife. When this key is inserted into the lock, the knife body remains on the extension of the key. This is dangerous, especially in the case of automotive keys.
In addition, other tools cannot be used when the key is inserted into the lock.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide an improved pocket knife, in particular a pocket knife which overcomes the disadvantages of the conventional pocket knives.

[0005]

According to the invention, the above-mentioned object is achieved by a pocket knife having the features mentioned in the independent claims, further advantageous forms are mentioned in the dependent claims. In particular, the object of the invention is solved by a pocket knife consisting of a key blank or a key, which is mounted like any other tool so as to pivot about a transverse axis across the pocket knife. The key blank or key is removable and can be separated from the knife in use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to embodiments shown in the drawings. The knife 1 shown in cross section in FIG. 1 is formed from a body 10 with two parallel sides spaced apart, only the rear side 11 being shown in the figure. ing. In general, the two sides are connected to each other by at least two transverse axes 12 and 13. Here, the shaft 12 serves as a pivot point for the cutting edge 14 shown in full extension. Other cutting blades or tools, not shown, can also be integrated into the knife 1, for example, the tool can be mounted on one or the other shaft 12, 1
3 or a pivot not shown. Such a configuration is well known.

According to the present invention, the knife 1 comprises a raw part adapted to be formed in a key. The unprocessed member 2 has a keyless unprocessed portion 20 and a mounting portion 21 whose body is long and substantially flat. This key blank has the shape and dimensions of a normal key blank,
The mounting portion 21 is mounted such that the member turns around the horizontal axis 13. In FIG. 1, the unprocessed member 2 is shown in a folded state. The user is the body 1
In order to remove the raw part 2 from zero, the part can be pivoted about a shaft 13. The back of the knife is provided with an elastic member 15 of a known type, which is fixed in place by a pivot. In the folded position, the elastic member 15 holds the unprocessed member 2
Presses the rear edge portion 25 of the blank 2 and when removed from the knife, the front edge portion 2 of the green part 2
Press 6. Therefore, the unprocessed member 2 is fixed at these two positions by the elastic member 15.

In the form of the unprocessed member and the key shown in FIGS. 1 and 2, the mounting portion 21 is provided with an opening 22. This opening allows the unprocessed part 2 or the processed key to be disengaged from the shaft 13 and thus from the body 10 and stored. To achieve this, the unprocessed part 2
Alternatively, the key 23 is partially removed in a position perpendicular to the knife body. In this intermediate position, the key or unprocessed member is in a stable state due to the pressing of the elastic member 15 against the edge of its end 27. Thus, the key or green member can be withdrawn by sliding the key or green member along the cutting edge parallel to the longitudinal direction of the knife toward the center of the knife until the shaft 13 is separated from the opening 22. it can. FIG. 2 shows the raw member 2 pulled out of the body of the knife 1. In this way, the unprocessed member 2 is removable. Therefore, the member can be separated from the knife 1 in order to make it into a key 23, or else the knife body 1
It is also possible to use it independently of 0. The unworked key member 2 or the processed key 23 can be stored again in the knife by performing the same steps in reverse order.

The key 23 or the unprocessed member 2 can be used separately from the knife, or can be completely removed and used while being integrated with the knife 1. The key or the key blank can only be removed at an intermediate position perpendicular to the longitudinal direction of the knife. Thus, the key 23 or the key blank 2 cannot be removed when they are folded into a knife or used in the removed position.

Preferably, the knife is sold with one or more green parts 2. In that case, the purchaser needs to process the unprocessed member at a specialty store in order to obtain a key suitable for the corresponding lock type and number of locks. The knife is
It can be sold or delivered with a processed key. For example, a car purchaser can be provided with this knife with an ignition key for a car. Because the key is removable, the key can be easily replaced regardless of any changes to the lock or the vehicle.

FIG. 3 shows a processed key 23.
In this key, the opening 22 is formed so that it can be removed when the knife 1 is pulled out to a position perpendicular to the main body. Thus, the key cannot pivot to the position where the knife is extended without removal. In this case, the shape of the mounting portion 21 and the opening 22 is such that the key can be taken out or stored again in the knife without any difficulty, even when used repeatedly. Can be very easily moored to the horizontal axis 13 of the vehicle. This arrangement is advantageous when it is preferred that the user not use the knife in the extended extension position of the knife. In the case of a knife with an ignition key of a motor vehicle, it is important, for example, that the user does not move with the key end of the knife 1 inserted into the dashboard. This is obviously a safety concern in the event of an accident, and in some cases poses a risk of impeding the operation of the vehicle's steering wheel or gearshift.

In the illustrated embodiment, the key or the key blank is arranged with the main teeth on the outer edge of the key in the folded position of the knife. Generally, this arrangement facilitates removal of the key from the knife by pinching the teeth between the fingers of a person. However, the keys can also be placed in the opposite orientation, such as with the teeth inside the knife when the keys are folded. In this case, a flute, or lot, is preferably provided near the edge of the back of the key to facilitate withdrawal. Similarly, a key with teeth or similar elements on the inside, outside two edges of the key or on the sides of the key can be used.

Of course, the knife 1 can have a number of green members 2 or hooks 23 arranged about a common axis or two or more different axes. The knife is
Any type of key can be provided, for example for a piece of furniture, for a vehicle or one operated by a key. Thus, the key or the key blank can have very different configurations depending on the application.
The key can also be an electronic key or a combination of electronic and mechanical keys.

The present invention likewise provides for the sale or distribution of individual or keyed or keyed blanks during removal of the pocket knife so that the keyed and keyed raw members can be pivoted about one transverse axis 12 or 13. Attachment section 21 having opening 22 so that members can be fixed
And the unprocessed member 2.
