Abstract

The present invention relates to a spring tool comprising two identical parts 2a-2b articulated along a common axis 3 and delimiting around this axis a central groove 21 which receives a spring adapted at its ends to slide on the branches 2a of the tool. The spring is one piece and has a general "U" shape. It has a central recess 17, located at the level of the central groove, as well as a recess 13 on each of its sides in order to free itself from the branches of the tool.

Description

-1-

Spring tool.

  Tools with two branches that are operated according to a point of rotation and whose opening is maintained by the action

  of a recovery spring, are of routine use.

  At present, the location and the shape of said spring impede the proper functioning of the tool insofar as the spring protrudes outside the volume of the tool itself, or to the extent that it interferes with the groove of the tool and with what the tool grasps, grabs, cuts, etc., or

because the objects do it.

  The invention recommends a tool with a payload

  which adapts to the volume of the tool, and which, because of the recesses are practiced in the spring, makes it possible to

  solve the problems listed above.

  The present invention relates to a spring tool comprising two identical parts articulated along a common axis on the circumference of which is a central groove which receives a sliding spring at its two ends along the branches.

  of the tool. The spring is one piece and has a configuration

  general ration in "U" with a curved soul which is placed in the central groove and fits in this part to the

  configuration of the tool. The spring has at least one decrement

  on each of its sides to free itself from the branches of the tool, and a hook at the end of each side to fit each of the branches of the tool. Thus, during the opening and closing of the tool, each hook can slide along the branch concerned, the spring being at all times maintained with the core against the central groove, the

  sides and hooks resting on the branches of the tool.

  The spring is also characterized by the existence of a third décrochemient located in the central zone of its curved soul. In addition, the hooks have at their ends

  recesses forming an angle "o <" with respect to the hook.

  FIG. 1 represents a plan view of a spring tool according to the invention. FIG. 2 represents a profile view of the tool

  spring according to the invention, corresponding to the previous figure.

  In these two figures, the branches (2a) of the tool (2)

are partially cut.

  FIG. 3 represents a top view of the tool with

  the heads (2b) and the branches (2a) open.

  Figure 4 shows a plan view of a spring (1M.

  FIG. 5 represents a profile view of the spring (1)

corresponding to Figure 4.

  FIG. 6 represents a view from above of the spring (1)

  shown in Figures 3 and 4 above.

  According to the invention and in accordance with the accompanying drawings, the spring tool comprises: two identical parts articulated along a key axis (3), each comprising a branch (2a), a head (2b) and a lateral withdrawal zone; at the place of the passage of the branch (2a)

  at the head (2b), where is the key shaft (3). This configuration

  ration of the tool thus forms a groove (21) and a "mouth" or

cavity (16) between the heads (2b).

  This cavity (21) houses a spring (1) whose ends

  adapt to the branches (2a) by sliding.

  The spring (1) is in one piece, with a general configuration in "U". It has the following features: - core (11) curved to fit this place to the configuration of the groove (21). The curve of this soul is in a semicircle (see Figures 1 and 4) - each of the sides of the spring comprises at least one recess (13) allowing it to be released from the branch (2a) of the tool (2), of varying thickness. This recess is located near the place where the core (11) and the sides (12) of the spring meet, it being understood that there may be several recesses (13) on each side (12) and that the others may be provided at other locations around the periphery - the core (11) further comprises at least one recess (17) to prevent the spring (1) from locking in the groove (21) or between the two parts of the tool (2). This recess is located precisely in the center of the core (11), it being understood that there may be more than one recess (17) and that one can predict or predict other recesses in other areas around the circumference - each of the sides of the spring (12) has an end hook (14) which fits on the branches of the tool (2) and can slide when opening and closing the tool . These end hooks (14) comprise a recess

  end (15) forming an angle "<" with respect to the hook.

  - It has been shown that the existence of the recesses (13) and (17) allows, when opening and closing the tool, that the core (11) curved spring (1) remains against the groove '(21) formed by the two branches of the tool

  without projecting into the cavity (16), this characteristic

  also facilitated by the

  end hooks (14) on the branches (2a) of the tool.
