Description

Spring clamp with hook The invention relates to a spring clamp having a clamping mouth with two clamping jaws which are spring-s loaded toward one another by the force of a spring and are formed by arms which are connected to one another in an articulated manner at the one end, and the other ends of which form actuating sections which can be moved toward one another in order to open the clamping mouth, the two abutting clamping jaws, together with the articulation pin of the arms, defining a reference plane. A hook may be arranged at the free end of one actuating section.
A spring clamp without a hook is disclosed in DE 200 Ol 498 U1.
Spring clamps with hooks are disclosed in US 1 468 884 and FR 1 325 394. In these documents, the hook can be used in order to suspend the spring clamp with hook, so that the clamping mouth of the latter projects downward in order for something to be clamped firmly thereon.
The spring clamps disclosed in these documents are also suitable, in principle, for being fastened somewhere by way of the clamping mouth, so that something can be hung on the hook. This functions, however, only in a horizontal position of the reference plane formed by the two abutting clamping jaws together with the articulation pin of the arms.
It is an object of the invention to develop a spring clamp with hook of the generic type in a functionally advantageous manner.
The object is achieved by the invention stated in the claims, Claim i, first and substantially, providing that the angle bisector between the two actuating sections is inclined at approximately 90° to the reference plane. This allows more ergonomic handling.

It is further provided that the hook is mounted such that it can be pivoted about an axis arranged at the end of the actuating section. It is possible then for the hook to be pivotable about an axis located substantially parallel to the reference plane. It is advantageous if the hook is arranged in a releasable manner on the actuating arm. The preferred bayonet connection allows the hook to be removed, and refitted, in a material-preserving manner. The spring clamp according to the invention may thus also be used without hooks, or it is possible for hooks of different sizes or shapes to be combined with the spring clamp.
It is further advantageous if the hook, when pivoted in, is located in a parallel position in relation to the actuating section. In a pivoted-out position, the hook then extends in the imaginary line of extension of the actuating section carrying it. The two actuating sections of the arms form grip zones, which are oriented away from one another in each case and may be covered with a soft-plastics material. The mutually facing inner sides can assume a parallel position in relation to one another when the spring clamp is open.
The hook, when pivoted in, is preferably located in a pivot-in space which is arranged at the inner side of the actuating section carrying it. The hook may be open. It is also possible, however, for the hook to be closed, or to be capable of being closed, by a closure in the manner of a snap hook. A closure tongue which is urged by a spring into the closed position is provided for this purpose. This closure tongue may have a curvature which is oriented in the direction of the inside of the hook. If the journal which mounts the hook projects from the end of the inner side of the actuating section carrying it, its end surface may form a stop against which, in the open position, a mating stop of the other actuating section contacts. It is provided that the angle bisector between the two actuating sections, this angle bisector running through the articulation pin, is located approximately perpendicularly to the reference plane. The spring clamp can then be used in the manner of a pistol grip.
The hook here is arranged on the actuating section which is located in the flat of the hand of the person actuating the spring clamp with hook. The actuating section which is located opposite the latter actuating section is rooted in the region of the clamping mouth.
This actuating section is grasped by the fingers. The soft-plastics grip zone which is positioned in the flat of the hand is longer than the soft zone which is grasped by the fingers. The hook can be pivoted through 360° about its bearing journal. The hook may also be pivotable about its axis which runs perpendicularly to this axis. According to a further variant of the invention, it is provided that the axis of rotation about which the hook is arranged in a rotatable manner on one of the arms runs parallel to the reference plane. An axial extension of the hook is preferably mounted by a retaining bracket which is arranged on the inner side of one arm. As a result, the axis of rotation of the hook is located almost in the reference plane. The axial extension of the hook is snapped into a bearing recess of the retaining bracket. For this purpose, the retaining bracket has a snap-action opening, through which the neck of the axial extension has to penetrate.
Exemplary embodiments of the invention will be explained hereinbelow with reference to attached drawings, in which:
Figure 1 shows a first exemplary embodiment of the invention in elevation, Figure 2 shows the exemplary embodiment according to Figure 1 in the open position, Figure 3 shows the exemplary embodiment according to Figure 1 with the hook pivoted out, Figure 4 shows the rear view of the exemplary embodiment according to Figure 1 with the hook pivoted in, Figure 5 shows an illustration according to Figure 4 with a modified hook pivoted out, Figure 6 shows an illustration according to Figure 4 with the hook removed, Figure 7 shows a further exemplary embodiment of the invention in elevation, Figure 8 shows a cross section through the exemplary embodiment according to Figure 7, Figure 9 show's a section along line IX-IX in Figure 7, and Figure 10 shows a section along line X-X in Figure 7.
The clamp has a clamping mouth. This clamping mouth is formed by two curved clamping sections of in each case one arm 3. The one end of the clamping section carries in each case one clamping jaw 2, these being pressed against one another by means of a spring (not illustrated). The other ends of the clamping sections meet in the region of an articulation pin 5, about which the two arms can be pivoted when the two actuating sections 4 are moved toward one another. The clamping mouth 1 then opens.
The two clamping jaws 2 clamped against one another form, together with the articulation pin 5, a reference plane E.

The end of one arm 3 carries a U-shaped hook 6. The two arms 3 may each be produced as an injection molding, a holder for the hook 6 being molded on one arm. The hook 6 may likewise be produced as an injection molding. In the case of the exemplary embodiment illustrated in Figures 1 to 5, the angle bisector between the two actuating sections 4, which can be gripped by the actuator's hand, runs approximately transversely to the reference plane E, which is defined by the separation plane of the two clamping jaws located one upon the other and also by the articulation pin 5. The angle bisector G thus runs at right angles to this reference plane. For this purpose, the arm 3 which has the actuating section 4 which is located in the flat of the user's hand is curved. The arm 3 which has its actuating section 4 grasped by the actuator's fingers, in contrast, is Y-shaped. The grip zone 15, formed by a soft-plastics layer, of the Y-shaped arm 3 is shorter than the grip zone 15 of the curved arm 3.
The two mutually facing inner sides 15 of the two actuating sections 4 form a pivot-in space 17 for a hook 6. The hook 6 can be pivoted about a journal 12 disposed at the free end of the actuating section 4 of the curved arm.
The pivot axis A, which is defined by the journal 12, runs at an angle [3 of approximately 70° in relation to the angle bisector G. The pivot axis A is located perpendicularly to the inner side 16 of the actuating section 4 which carries the journal 12. In the pivot-out position, the hook 6 thus forms a 180° extension of the actuating section 4 (see Figure 3).
As can be seen from Figures .4 and 5, the width of the U-shaped hook h~ is greater than the width of the grip zone 15.

It can be seen from Figure 5 that the hook 6 can be pivoted about a pivot pin 20. The pivot axis B defined by the latter is located perpendicularly to the pivot axis A, which is defined by the journal 12.
The hook 6 has two legs forming a U-shape. The leg 7 of the U is configured to be longer than the leg 9 of the U, and the resulting hook opening can be closed by means of a closure tongue 18. This closure tongue 18 is resiliently mounted in the direction of its closed position and thus forms a carabine-hook closure. The closure tongue 18, furthermore, is curved towards the inside of the hook. The closure tongue 18, in addition, has an end hook by means of which it enters into an opening of the leg 9 of the U-shape.
The particular arrangement of the two actuating sections 4 with the clamping mouth 1 of the exemplary embodiment illustrated in exemplary embodiments* 1 to 6 gives this spring clamp a novel method of actuation. It can be held in the manner of a pistol grip.
The arms 3 have a U-shaped cross-sectional profile and consist of plastics material. The hook 5 also consists of plastics material.
As can be gathered from Figure 6, the hook 6 can be separated from the clamp. The clamp is connected to the hook 6 via a mushroom-shaped pin 20, which can be clipped into a corresponding pocket of the hook.
In the case of the exemplary embodiment illustrated in Figures 7 to 10, the hook & likewise has an opening which is closed by a tongue 18. The tongue 18 is integrally formed with the material ~f the hook 6 and forms a film hinge 22. The hook 6 has an axial * Translator's note: * Figures -extension with a round section 26, which is followed by a neck 24 of reduced cross-section, on which a circular-disk end section 23 is seated.
The axial extension is mounted in a retaining bracket 21 of an actuating section 4 of one arm 3. The retaining bracket 21 here is located in the region of the inner side 16 of the actuating section 4, that is to say between the two arms. The arrangement of the axial extension at the retaining bracket 21 is achieved in the manner of a snap-action connection. For this purpose, the retaining bracket 21 has a snap-action opening 25, through which the neck 24 can be snapped in. The positively locking axial securing action takes place with the aid of the circular end section 23 and of the round section 26. In the case of this exemplary embodiment, the axis of rotation of the hook 6 runs parallel to the connecting line E.
