Abstract

The system arranges a set of hooks in standard individual lots with each lot comprising a standardized number of hooks. The hooks are aligned one against the other and secured by a strap (2A). The strap retains the hooks such that the strap can be freed from the hooks by exercising simple traction or torsion on pallet (20) when the lot is positioned in a hand opposite to hand carrying a hammer.

Description

The present invention relates to the packaging of hooks cover.

It is known that, for fixing slates or shingles roofing, hooks are used.

In a first form, the hooks comprise a first tip end, which is stitched in the trench.

In a second form of hooks, this first end forms a clip which clamps on parallel mounted battens. In both versions, the hooks have the same second end opposite the tip or staple, which forms the retaining clip of the cover element, slate or shingle.

These brackets are currently and always bulk or in large numbers on supports in their packaging (wooden box). When they are employed, the roofer must untangle them from each other or take them in large numbers, several tens causing multiple manipulations and place them side by side. side in hand opposite to the one holding the hammer, the way illustrated in FIG. 3 of the accompanying drawings.

This is a tedious and time-consuming operation, and as a result expensive because it considerably lengthens the exposure time.

The present invention results from the search for a solution effective and simple to this problem, consisting of conditioning hooks ordered to facilitate their grip and their limited scheduling in the hand.

The invention is therefore a system for packaging hooks single-use and manual cover, characterized in that consists of an individual regulatory batching comprising each a standard number (6 or 7) of a plurality of hooks aligned with each other, and thus subject to a tie or stick, which holds the hooks of the lot in a way such that when the lot is positioned in one hand, ready to use, it can be released from said hooks simply by pulling between two fingers, on the off-center side pad so that this separation operation of said stick with the hooks is easy despite the other hand having to hold a hammer at the same time.

According to the invention, two versions have been developed said stick manufactured in a consumable material technical tape adhesive with properties in terms of bad weather and in the respect the environment. Both versions have been designed to cooperate with the right-of-way segments of the rods or bodies of brackets said versions being positioned mid-length of these latest.

In the first version mentioned above, the stick has the shape of a small asymmetric closed-loop shaped magazine pouch transversely encircling the segmental segment of the right-of-way adjacent rods forming the bodies of the hooks by marrying the periphery over 360 ° thus forming the subjugation of scheduling an individual batch of said hooks in number limited standard. The stick separates from the hooks by opening by traction exerted in one of two possible directions of their width towards either end of hooks in their length indifferently for right-handed or left-handed (inversely opposite).

In the second version, said stick has a profile offset symmetrical, declined from the first version by cooperating with the hooks stems like the first version, and which separates from the batch of hooks in the same way as before described for the first stick.

When using hooks packed in accordance with the invention, the roofer no longer has to unravel them one by one in their box to place them in hand. Thanks to the stick, it performs this operation of a gesture, opening the latter by simple traction exerted between two fingers on the pallet in one of two possible reversed directions, in the direction of the length of the hooks.

This gesture, which should be called a pickaxe, does not not to get rid of the hammer to be accomplished, which is mandatory for gripping hooks in bulk requiring a disentangling. Similarly are deleted thanks to the stick all these other frequent parasitic gestures consisting of taking during a laying phase to make each rank of the orne or ladder slate strip that realizes the roofer whenever he moves his ladder and who for reasons of safety and ergonomic possibility is limited to 6 or 7 slates numbers commonly chosen by roofers for pose of each of the constituent ranks of the said (ourne), these numbers standardized by the stick on the basis of slate formats and in corollary limited by the arm length (lateral pose) and adapted by professionals, both batching standards said two numbers (6 - 7) are of course susceptible to vary for specific reasons (region, format).

Fig. 12 is a triptych of views illustrating a suggested technique for each stick deposit at the end of laying each of the rows of hooks composing the urn.

Considering first Figs.1 and 2, they represent each a plurality of hooks 4 suitably arranged between them, namely aligned against each other, to match the scheduling in hand, Fig.11, of a limited number of hooks standards of 6 or 7 of these for the realization of each standard rows of slates making up the orne of slates that the roofer makes with each movement of his flat ladder on crawling roof) as it is commonly practiced by professionals, the width of each row of the latter being limited and correlated with the length of the arm (like the current presentation of the packaging of hooks) in bulk in their wooden box (containing up to 900 units) requiring for each row their take by handle (shaking) in diffuse number imposing a detangling, hook by hook (forming a cluster) and looking for the presentation of their fixing end (to be pointed in the wooden support).

The hooks 4 of Fig.1 and Fig. 2, have in common the three parts making up the hooks, their rod 5 (or body), the end clip portion 7 for retaining the elements of cover and their fixing end 21 to point. They do not differ than by said end 21 of the second form of hooks the fixing end with clip 21a shown in the right view FiG. 8.

Starting from this first observation, the sticks according to the invention intended for assembling the hooks of the same batch to the Fig.2, have been designed to operate preferably in the middle position of the length of the rods 5 that the two types of hooks ; and although they have been represented in the drawings for batches of six or seven hooks (standard) these are of course likely to vary ex. : (region, specific format slate etc).

In the embodiment of Figs.2 to 8 and 10, the stick according to the invention, designated by the reference 2A, is a small case charger closed laterally, and open symmetrically from each side transversely in the longitudinal direction of the scheduling for securing the rods or body 5 of the hooks 4, encircling and marrying the periphery of the captive segmental parts S (60) of said rods 5 of the hooks 4. It has a transverse body or more precisely in closed loop at the charged stage composed of a single ribbon (unlike other techniques composed in pairs) mechanically formed by different processes Fig 9, the latter has an asymmetrical profile with the clasps 29 offset laterally (positioned to the right on the views) forming the mono pallet (20) which when used by the roofer becomes the element allowing the opening of the stick. The asymmetrical profile offset thus formed has two parts in continuity the front 1 Fig. 6 extended by the back 3 to the back 0 said formed parts in continuity by a single ribbon are contiguously 54 for the closing said asymmetric profile by the fastening parts in common 29 to form a double stratum constituting said mono pallet 20 exerting the closing and the lateral locking of the hooks associated with returns or dihedral 3. The inner profile 60 wife 360 ° in tense mode in accordance with the periphery of the sequencing of the segmental parts S60 of the rods 5 so appropriate, it is preferable when presenting batches of hooks to provide longitudinal adjacent clamping without clearance of hooks to perfect the homogeneity of the batches when laying the sticks for their transfer (limitation of the longitudinal twisting of the lot 10).

The adhering portion in adhesion 32 of the front 1 in the loaded state is formed in U by the returns or dihedral 3 which marry (by pressure exerted by process P17 advantageously and respectively the sectors of the outer semi-circumferences of the captive segments S (60) of said rods of the adjacent hooks 4 ^e of the lot10, in continuity respectively towards the back 0, and by the fillet 11 with the clasp part 29, said front 1 in adjacency 54 forming the pallet 20 allowing the control of the relative torsion of said batch thus held tight without clearance forming a plurality of cells 8 between each pair of captive segments S60 of the rods 5.

On the other hand, the interface of the back part forming the profile 60 may include a neutralization 19 of the sizing by (talc wax, etc.) applied by the process P26 on the half periphery AR14 allowing the back 0 not to adhere to sectors S 60 corresponding rods (interface 19) with said part of said back 0 forming the profile 60 allowing the sliding the along the S60 segments of the hooks at the opening of the stick fig. 7 without causing its disintegration. This solution technique allows to keep in its entirety the stick and to release the hooks controlled during all the laying by the thumb of the hand now the lot fig. 11 not having to take off the hooks one by an operation made difficult by the taking of the rods 5 exhibiting small diameter the roofer can replace the entire stick on the last hook of the lot (triptych) FiG. 12 to put on the surface worked (repeated operation on each last hook of each standard rank composing the urn) with the double advantage of not pollute the environment, not visually because they are hidden by the overlapping part of the slate (pureau), said stick being previously stored on top of the carrier hand of the front lot to be placed exclusively on the fixing part of the last hooks of said batch (tip or staple).

The facilitated opening without disintegration of the stick results from the combination of the asymmetrical profile on the one hand, the rectilinear back 0 does not notch the segment of the border hook 4 ^e on the side of the pallet 20, on the other hand it includes the two primers 23 opposing diametrically and in line prepositioned on each of the fields of the back 0, by machine process P47, between said hook border 4e above and its adjacent hook 4 inside to facilitate the opening in (11) in one of two possible directions for right-handed or left-handed all the optimization of said asymmetric profile allied to the neutralization 19 to give an incomparable performance while asking only a small contribution of time and little dexterity on the part of the user.

It should also be noted that the outer paper side can make subject of a treatment or surface preparation 15 to receive an inkjet marking (logo mark etc.)

Fig. 10 illustrates a first way for right-handed separate the stick 2A from a batch of hooks, after the user, hammer in hand, made a pick with the other hand without having to face the box of hooks (ergonomics). With the help of hand holding the hammer the user only has to drop the stick triptych left on the spot (surface worked), technical not inducing any environmental pollution nor environmental pollution the more the material constituting the stick is biodegradable.

A second embodiment of the stick 2S according to the invention is illustrated in FIG. 4, it does not differ from that of first stick 2A only by the shape of his profile formed from the front 1 and back 0 compound symmetrically off-set by the mono pallet 20 taking the sectional shape of a closed waffle mold.

It will also be noted that said second stick 2S benefit from the technical criteria facilitating separation in its completeness in the same way as for the first stick 2A said stick is no longer used for so-called special hooks curvature, the separation of the latter from the hooks is identical to that previously described for the first stick to Offset pallet, the traction between two fingers is exerted inversely (for right-handed and left-handed) in torsion on said favored pallet in both cases by the predetermined aperture primers 23 that has the back 0 of the mono pallet 20 side.

Optimization of the technique of the invention provides like other techniques, an opening for the separation of sticks with hooks without disintegrating them, inducing in the opposite case the presence of residue on the extrados of the hook rod part, a risk vector of leakage, said residue being able to cause capillarity under the overlapping part of slate (pureau) separation of the sticks in their entirety makes it possible to deposit them in repositioning exclusively on the respective fixing end of two types of hook 4 with a point 21 or a staple 21a of the last laid hook of each lot 10 previously described or in a pocket on the belt, respecting the environment without risk infiltration. The profile technique of the present invention a single pallet 20 ensures a substantial saving of consumable ribbon of the order of a third unlike the paired techniques (double pallets) plus said mono pallet 20 intangibly placed on the same right side (meaning adopted) allows when taking each batch to directly index the orientation of the fixing end by preselecting the laying direction of the hooks
