Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a holder for a portable knife, particularly for a diving knife.

[Conventional technology]

Generally, the knife that a diver carries when diving is attached to the waist, arm, or leg of the diver using a holder that allows it to be taken out and stored easily and securely in case of an emergency situation in a unique underwater environment. .

To this end, this type of holder includes a sheath for housing the knife and a hand or belt loop for connecting the sheath to the arm or leg of the knife. When attached to the body, the holder is fixed with its upper end opening facing upward, or because the swimming position of the dipper in the water changes in various ways, such as from a normal position to an upside-down position, the upper end opening is often in a position facing downward. become.

In preparation for such a case, this type of holder must be designed to prevent the knife stored in the sheath from falling out.

Furthermore, the knife removal prevention means in this holder is required to be able to be removed quickly when necessary, such as in the above-mentioned emergency situation.

As an example of a holder that satisfies these conditions, the applicant of the present invention previously proposed a means described in Japanese Patent Publication No. 13759/1983, which has been put to practical use and has been well received.

(Problem to be Solved by the Invention) The knife removal prevention means in the above-mentioned conventional holder consists of an annular member into which a knife grip is inserted as a safety device when not in use, and a collar of the knife that is used when in use. A double locking means consisting of a single stopper that fits together is adopted, and in particular, this stopper is configured so that when the knife is extracted, the stopper is pulled up with the tip of a finger to separate it from the engagement position with the collar. has been done.

Although this configuration allows the knife to be pulled out and stored easily, since the pull-out end of the stopper protrudes from the upper surface of the sheath, if you accidentally touch this, the stopper can be removed easily. There was still room for improvement, as there was a risk that the stopper would come off and the knife stored in the sheath could fall out.

SUMMARY OF THE INVENTION An object of the present invention is to provide a knife holder that allows a knife to be attached and detached with a simple operation and that can prevent the knife from falling off accidentally.

Another object of the present invention is to construct the holder in such a shape that the entire holder can be constructed from a molded body of synthetic resin.

Furthermore, other objectives will be understood from the description below.

(Means for Solving the Problem) In order to achieve such an object, in the present invention, a stopper for preventing the storage knife from falling out is provided by an arm integrally formed with a sheath made of synthetic resin and a cross-section of the tip thereof. Consists of letter-shaped members.

The L-shaped members are arranged independently on both sides of the upper end opening. One side of this L-shaped member is the locking side that comes into contact with the back of the flange of the storage knife.

The other side edge is used as an operation end, and by pressing this, the arm is moved out of the action area for the locking side and the back of the flange under elastic deformation of the arm.

Further, a receiving piece integrally formed with the sheath portion faces the limit region where the L-shaped member of the stopper is pushed down.

The sheath part is constructed by combining a front side member and a back side member which are divided into two into a housing, which are joined together by screws from the back side member.

A guide bank is integrally formed on the inner surface of the sheath of this back side member along the entry path of the knife housed in the sheath.

Further, this back side member is extended from the upper end opening to constitute a back rest piece along the knife grip, and a belt passage hole is formed on the back side of the back rest piece.

The arms extend from near the outer side of the upper end opening of the back side member in the sheath portion toward the left and right side edges of the back support piece, and the locking side of the L-shaped member at the tip thereof is located on the surface of the back support piece. It rises with a gentle slope from the front to the rear, which is depressed.

[For production]

According to the above means of the present invention, a stopper is provided between the sheath portion and the backrest piece, facing the upper end opening. That is, the locking side of the L-shaped member of this stopper comes into contact with the back of the flange of the stored knife, and functions as a retaining member. At this time, the arm supporting the locking side works to return and hold the locking side to the position of contact with the back of the brim based on the elasticity of the synthetic resin material of which the arm is made; When the edge of the other side of the L-shaped member is pressed with a fingertip, the elastic deformation functions to move the locking side away from its action area.

Moreover, since the L-shaped members that act in this way are arranged independently on both the left and right sides of the upper end opening, only when they function simultaneously can the locking action on the back of the collar of each locking side be performed. Once untied, the knife can be removed from the sheath.

The receiving piece keeps the arm deformed by the compression in a region where it can be elastically restored when the pressure is released, thereby preventing breakage of the arm.

The sheath part is formed by joining two split front and back members together with screws, and the inner sheath itself and the guide ring can be formed by molding. The sheath can be worn by passing a belt or band through the belt passage hole and tying it around an arm or leg.

The arm, which extends upward with a fixed end near the outside of the upper opening, elastically supports the L-shaped member at its free end, and the posture of the locking edge in the normal supporting position is along the surface of the backrest piece. The movement of the inserted knife is not hindered, and an abutting and engaging surface against the back of the collar can be secured.

(Example) A detailed description of the present invention will be given below with reference to the drawings.

FIG. 1 illustrates a holder according to the present invention and a knife stored therein. This holder main body 1 consists of a front side member 1a and a back side member 1b molded from synthetic resin (for example, polycarbonate).

These are integrally connected and formed by means to be described later. The part to which the front side member 1a is connected is a hollow sheath part 2, with stoppers 4 facing on the left and right sides of the upper end opening 3. Furthermore, the back (11 member 1b is
A backrest piece 5 is formed extending upward, a belt passage hole 6 is provided on the back side of the backrest piece 5, and a receiving piece 7 integral with the scissors piece 5 is provided on the lower side of the stopper 4. A band passage hole 8 is also formed on the back side of the sheath tail of the main body l.

The knife 9 housed in this holder main body 1 is a normal dieper knife, and what is particularly noteworthy is that a flange 10 is attached to the base of the blade.

As shown in the plan view of FIG. 2 and the side view of FIG. 3 with the sheath partially broken, the sheath 2 covers the front side member la along the outer periphery of the part of the back side member ib, The screws 12 are inserted and tightened through screw holes drilled at corresponding positions in the back side member 1b through the screw holes 11 arranged at intervals on the fitting sleeve of the member 1a. Part 1
A and the back side member ib are joined together.

Further, a guide ring 13 is formed upright on the part of the back side member 1b that corresponds to the sheath 2 along the insertion path of the blade of the knife 9, so that the knife 9 to be stored can be inserted smoothly. None.

The stopper 4 is composed of an arm 4a that projects upward from a position below the upper end opening 3 of the back side member 1b, and a member 4b having a rectangular cross section at its tip. This arm 4
a can be elastically deformed by the elasticity of the material formed integrally with the back side member b, and in its normal shape, the locking side 14 on one side of the L-shaped member 4b at the tip can be used to hold the stored knife. The position where it comes into contact with the back side of the tsuba lO of No. 9 (the third
(See the solid line in the figure and FIG. 4), and the member 4
When the upper end of the operation side 15 on the other side of b is pushed down with a fingertip against the elasticity of the arm 4a (see the position shown by the chain line in FIG. 3 and FIG. Retreat from the contact position. The lowermost position of the locking side 14 is regulated by the contact between the locking side 14 and the receiving piece 7. Moreover, the locking side 14 that functions in this way is
As shown in FIGS. 3 and 3, it is formed into an inclined surface that gently rises from the upper end depressed to the surface of the backrest piece 5 toward the lower end that protrudes. The abutting end of the knife 9 is secured, and the tip of the blade of the inserted knife 9 does not come into contact with the locking edge 14.

Things to be careful of when pressing the operation side 15 above are as follows:
Place Miki's finger on the little finger side on the side of the knife grip, and sandwich the grip between the base of the thumb and the base side.
The remaining thumb and forefinger are used to simultaneously press down the operation sides 15 on both the left and right sides. As a result, the locking sides 14 on both sides
are removed from the collar 10, and the knife 9 can be pulled out from the sheath 2 only by the operation in the drawing direction on the holding side.

Of course, along with this pulling operation, the suppressing action of the thumb and forefinger on the operating side 15 is released, and as a result, the L-shaped member 4b returns upward to the fourth illustrated position due to the elastic return force of the arm 4a. Therefore, when storing the knife in the sheath 2 again, the raised L-shaped member 4b, that is, the locking edge 14 having a lower end protruding from the surface of the backrest piece 5, is connected to the intruding tsuba IO. 2 and 3, the tsuba 10 climbs over this and hits the upper end opening 3.
In the illustrated state, the returned locking edge 14 locks and holds the knife 9, so that the function of preventing the housed knife 9 from falling out is exhibited.

(Effects of the Invention) Since the holder of the present invention has the configuration as described above, it has the following effects.

The stopper that locks the flange of the stored knife is composed of an elastic arm made of a synthetic resin molded body and a member shaped like a cross section at the tip of the elastic arm. Since they are arranged independently, first, by pushing down the other side of the L-shaped member with a fingertip, the L-shaped member is moved out of its locking area, and the knife stored in the sheath can be easily pulled out. be able to. In addition, since the knife hook is released by this pressing operation, it is performed independently by the left and right L-shaped members that are independent of each other, so it must be done simultaneously on the left and right sides. Even if it happens, the locking and holding effect of the other side is maintained, so it is safer as a means to prevent it from falling off, and therefore,
Double hooking in conventional means can omit the stop. Moreover, when the pressing force on the L-shaped member is released, the elastic restoring force of the arm based on the elasticity of the material allows the member to return to the locking area, and there is no need to use a spring member for this purpose. Compared to conventional means, components can be omitted.

Further, by providing the receiving piece according to claim 2, when the L-shaped member is pressed down when releasing the lock, the support arm can be kept within the range of elastic deformation, and an accident of breakage of the arm can be prevented. can.

Furthermore, by constructing the sheath portion as a combined housing of a front side member and a back side member, a hollow sheath can be easily obtained by synthetic resin molding.

According to the configuration of the sheath made of this mating housing, it is possible to form the guide bank according to claim 4, and thereby the knife plate inserted into the sheath can be held without the cutting edge getting caught on the inner wall edge of the joint. , it can be inserted smoothly.

Furthermore, by providing the back support piece according to claim 5 and forming a band passage hole on the back side thereof, the blade edge etc. do not directly hit the skin or wet suit when inserting or removing the knife, so there is no risk of damaging the same. Since there is no slippage, this insertion/extraction operation can be performed safely and quickly.

According to the structure of claim 6, the arm is integrally molded and its elasticity can be easily maintained, and the operation of storing the knife by inserting it into the sheath along the surface of the backrest piece is also possible due to the arrangement of the stopper. This can be done extremely smoothly and safely without any hindrance.
