Abstract

It is formed of a monopiece body (1), made of rigid plastic, with a hollow inside (3), open on both ends (4), as well as by a longitudinal groove (2), and its outside surface opposed to such a groove, is anatomically formed (5-6) to adapt it to the user's hand palm in such a way the the cutting holder (7) acceedes to the body inside (1) through the groove (2), and said body (1) becomes the new handle, with a much ampler and comfortable holding surface.

The handle may constitute, besides, the exorning head of a key-holder, the complementary case of a lighter, etc.

Description

OBJECT OF THE INVENTION.

The present invention refers to a handle specially built to constitute the complement or complementary holder of another holder, of a cord, a string or any other element which, due to its reduced section or to the weight or load that it supports, tends to produce a cutting effect on the user's hand. Such is the case, for instance, of parcels having a considerable weight and tied with a string where the string constitutes the only transporting handle, or the case of - bags with very thin handlers or which become stilized when the said bags are loaded, as well as those bags which incorporate a string as closing and holding means
The complementary handle being proposed herein is usable, as may be further on, to gather and collect among them several objects provided with holders of the above-mentioned type.

BACKGROUND OF THE INVENTION.

In any of the above cited cases, for instance, when it is required to manually transport a considerable weight having as its only holding means the cord itself with which it has been tied, the weight obviously concentrates practically on one line, the only one where the string is supported on the user's hand, which causes a cutting effect which makes handling extremely uncomfortable, even painful, which in extreme cases may even result in a true cut, as, for instance, when the package tie has been performed with a wire element.
There are working gloves adequatedly structured to avoid such effects, but which are obviously only used when the - above-mentioned problems are centered on a person daily - work, being inimaginable to use the said gloves in such sporadic cases as, for instance, the problem arising on a shopping day in view of the eventual necessity of picking up a parcel at a transportation company, etc.
In such sporadic cases, it is a general custom to wrap the cutting handle with a handkerchief, a piece of cardboard or any other appropiate element, so tending to considerably increase the said handle surface at the holding area, although, obviously, any of these solutions is bothersome and little practical.

DESCRIPCION OF THE INVENTION

The handle proposed by this invention has been conceived to fully satisfactorily solve these problems, constituting an object easily transportable in the pocket, which - may even participate in a complementary functionality, such as to constitute the exorning head of a keyholder, the containing case of a lighter, etc., which may be used, at - any time, to adopt it to the cutting handle in question, - turning it into a handle with a large surface, anatomically adaptable to the hand's palm and which consequently will allow to support considerable weights without suffering the slightest harm in the hand itself.
To this end, and more concretely, the handle being proposed is constituted starting from a monopiece body, preferently obtained by moulding or injection based on rigid plastic material, with an elongated configuration, according with the hand's width and with a rounded and dimensionally ample section, with the special particularity that the said body incorporates a longitudinal groove as an access to its holow inside and open on both ends, which allows to gather in its inside the string, cord or handle in question.
As is evident, and in line with the above-mentioned explanation, in the hollow inside of this monopiece body may be collected the strings or cords of several parcels acting then this invention's handle as the union link or common - handle for all them.
As from this basic structure and in line with a preferred example of a practical embodiment, said handle will adopt in its area opposed to the above-mentioned longitudinal groove, an anatomic configuration to adapt the hand fingers in order to facilitate its grasping, and which, consequently, makes said handle more comfortable in a working situation.
Also in line with the above preferred practical embodiment example of the invention, the monopiece body incorporates two inner longitudinal flanges in correspondence with the above-mentioned groove, sensibly convergent in such a way that the said flanges act as retaining means for the holder, thus avoiding an eventual or accidental disengaging thereof in regard with the cord or handle to which it has been coupled. It may be mentioned, in this sense, that said flanges have their ends bevelled in order to facilitate the disengagement of the holder when this is voluntary, since the bevels of any one of the ends of both flanges configurate an opening divergent towards the ouside, which facilitates the "concentration" of the handle towards the groove's middle plan.
It may finally underlined that, as it has also been - previously said, this monopiece body may constitute an isolated element, with no other utility than the one exposed, or either be fitted with any other complementary utility, constituting, for instance, the exorning head of a keyholder, the containing case of a lighter, etc., without this affecting the invention essence, and with no other trouble than adequately modifying its inner structure.

DESCRIPTION OF THE DRAWINGS

In order to complete the description being made and in order to help to a better comprehension of this invention specification, it is enclosed to the present specification, as an integral part thereof, one drawing sheet in which, with an illustrative non limitative character, has been represented the following:

Figure 1 showing a side elevation view of a complemen tary handle for cutting holders or similar, performed according with the subject of the present invention.
Figure 2 showing a profil of the same handle.
Figure 3 showing a cross-section of the handle according with the cutting line A-B of Figure 1.
Figure 4 showing a further cross-section, in this case according with the cutting line C-D of same Figure 1.
Figure 5 showing a longitudinal section of the handle, according with the cutting line E-F of Figure 2.
Figures 6 and 7, showing finally two of the multiple possible practical embodiments of the handle respectively corresponding to its realization in the exorning head of a keyholder, or the containing case of a cigarette lighter.

PREFERENTIAL EMBODIMENT OF THE INVENTION

From the examination of these figures, it may be noted that the complementary handle being proposed is constituted as from a monopiece body (1) which, as it has already been said above, will be preferentially obtained based on rigid plastic material, with an elongated body of considerable - section and provided with a longitudinal groove (2) to access to its hollow inside (3), which will, besides, be open on its ends, as it may be perfectly noted on Figure 5.
The body is fitted in its outside with a series of protuberances (5) and notches (6), alternated, disposed in opposition to groove (2) being determinant on an anatomic surface to adapt the hand fingers, with the obvious exception of the thumb, for which there will be four notches (6) uniformly distributed as may also be seen in Figure 5.
The hollow inside of the monopiece body (1) is destinated to hold, receiving it through the groove 2, the cutting handle (7) or similar element in question, belonging to the bag (8) or to another object.
In line with a preferential practical embodiment of the invention, the monopiece body (1) will be provided in correspondence with the edges of groove (2), with longitudi nal flanges (9), each turned onto its inside, acting as retaining means disabling an eventual or accidental disengaging of the holder or similar (7), since in the event of an also eventual turn, for instance, of body (1), the handle will be engaged in one of the necks (10) defined by these flanges (9).
That notwithstanding, said flanges (9) present their extreme edges (11) bevelled, as it may also be noted on Figure 5, in order to facilitate the disengagement of the handle (7) when this is done voluntarily.
As from this basic strecture, it is feasible to convert the body (1) into an exorning head for a keyholder by just opening on it a small orifice (12) in the appropiate place as shown on Figure 6, for the engagement of the chain (13) which will relate the head (1) with the keyholder ring or either, and in line with the representation of Figure (7), the housing for the holder (7) may be majoritarilly reduced in such a way that withing the body (1) a second majoritary housing be established, open towards one of the body ends and closed on the other, transforming the handle into the exorning case of a cigarette lighter (15). Obviously, these two possibilities shown on Figures 6 and 7 are merely as examples, since the handle may have any other - complementary and different function from those exposed above.
It is considered unnecessary to make a more extensive explanation for any expert in this subject to understand the scope of this invention and the advantages derived therefrom.
The materials, shape, size and disposition of all elements are susceptible of changes, providing this means no alteration of the invention essenciality.
The terms with which this specification has been described should always be taken in their widest and non-limitative sense.
