Abstract

1. One-piece plastic clothe peg of the type comprising two branches (2,2', 3,3') fast one with respect to the other via a thinned bridging (4) between the middle parts (1, 1') in opposite relationship to the two branches (2,2', 3,3') with interposition of an elastic element between the rear parts of the branches (3, 3') which element is constituted by resting the two ends (6, 6') of flaps (5, 5') one over the other, after bending backwards (11, 11') thereof, characterized in that said flaps (5, 5') are produced by partial cutting (8, 8') according to a U-configuration base of each back branch (3, 3').

Description

The present invention relates to a clothespin

  made of one-piece plastic material ".

  In this area it is known: A clothespin 5. A clothespin A clothespin A clothespin knuckle. The elements; 10. A wooden clothespin - metal spring; plastic material - metal spring; metal in one piece; plastic material in one piece with plastic spring binding the two

  plastic YOYO form.

  The purpose of the clothespin according to the invention is to: Allow the simplification of manufacture (in particular the shaping step); 15. Allow to improve the grip;

  Allow use as a toy.

  This is obtained by a plastic clothespin whose two branches are secured to one another by a thinned bridge of the same material between the middle parts

  vis-à-vis the two branches with an elastic element inter-

  placed between the rear parts of the branches and which is

  in that said clothespin is made of a material

  plastic of the polypropylene type, and in that the elastic element

  that consists of two tabs whose two ends are supported on one another after being folded by

  compared to the bottom plan of the branches.

  According to another characteristic of the invention, the two branches have a "U" -shaped section, the bottom of which comprises a "U" -shaped cutout, of which the uncut portion defining the elastic folding hinge zone is disposed on the opposite side. rear of the back branches. According to another characteristic of the invention, the

  length of the tabs and the position of the hinges are such

  that the support of the free end of the tongues is achieved when they undergo a flap backwards

  about 130 from the bottom plane of each branch.

  According to another characteristic of the invention, at the end of the rear branches, a vertical partition connects

  the two wings of the "U" section of the branches.

  This partition is intended for the positioning of the first

  knuckles of thumb and forefinger during use.

  According to yet another characteristic, the vertical side walls of these "U" have, in the rear part

  branches, one or more cylindrical perforations.

  The front part of the branches has at its end, on the

  external flanks of the vertical partitions of the "U", the proemi-

Cylindrical sides.

  The thickness and diameter of these prominences are such that they can enter and get stuck in the perforations of the back of the branches of another clamp of the same type allowing to

  serve as the pliers as a building element.

  By way of illustration, drawings are attached which represent:

  Figure 1: A perspective view of the whole.

  Figure 2: A detail view of a back branch with the

folding the tongue.

  -3- Figure 3: A view of the positioning of the first phalanx of the index finger and the thumb on each of the back branches

from the clothespin.

  The clothespin as shown comprises: two integral branches 2.2 '3.3' of each other by a thinned shank 4 of the same material between the median parts 1.1 'opposite the two branches 2.2' 3.3 ', with an elastic element

  interposed between the rear parts of the branches 5.5 '.

  Said clothespin is made of a plastic material of 1 polypropylene type, and the elastic element is constituted by the setting in abutment 6.6 'on one another of the two ends of the tongues 5.5' realized on each of the rear branches 3.3 '

  after folding backwards thereof 11.11 '.

  In addition, the clothespin shown comprises: branches 3.3 'with a section "U" 12.12' whose bottom has a cutout "U" 8.8 'whose uncut portion 7.7', defining the hinge zone of elastic folding , is

  arranged on the rear side of the rear branches 3.3 '.

  In addition the clothespin shown comprises: A length of the elastic elements 5.5 'and a position of the hinges 7.7' (or flap line) such that the support of the free end of the tongues 5.5 'is achieved when

  these undergo a flap of about 130 11.11 '.

  The present invention aims to improve the production in the sense that the piece comes out of the metal mold

in one piece.

  The object manufactured by injection has pre-disconnected tabs

  by contact these three metal mold joint planes

side of these tabs.

  _4_ The final positioning of the tabs is as follows:

  The piece is ejected from the mold, received on a trans-

  carrier, oriented, engaged in a corridor where it is posi-

  If it is flat, advance step by step to a position where push rods push the tabs to bring them into contact with each other.

  their end by turning about 130.

  This operation taking place during the pre-stabilization period

the room.

  It can be provided then a mapping, labeling.

  In addition, the clothespin shown comprises: At the end of the rear branches 3.3 ', a vertical partition 14.14' connects the two wings and the bottom of the section "U"

12.12 'branches.

  This partition serves as support for the first phalanges of the thumb and forefinger and prevents the forceps from sliding forward during use, especially when the housewife has wet hands. In addition, the clothespin shown has on the vertical side walls of the rear part of the "U" branches 3.3 'one or more perforations 10. 10' cylindrical, the front part of the branches 2.2 'having in

  its end, on the outer flanks of the vertical partitions

  the "U", 9.9 'cylindrical prominences, the thickness and diameter of these prominences being such that they can enter and get stuck in the cylindrical perforations 10.10'

  from the back of another clamp of the same type.

  The use of this type of clothespin as a construction game, by the possibility of nesting the tongs into each other, gives rise to another dimension to the attractive side traditionally used by clothespins on children. The aesthetics and dimensions of this clothespin will vary without changing the design described above. -6 -
