FIELD OF THE INVENTION

This invention relates to a carrying set for carrying objects by use of a hooking handle and its accessories.

In general goods are carried by means of containers, some of which are encumbering and troublesome to handle and this may be tiring for people.

Moreover, for some objects a suitable carrier is often difficult to find. For this reason people going shopping carry bags, sacks, and boxes. Unfortunately, the handles of plastic bags and the strings of packages often “cut” the hands.

This is an improvement patent over Stoft (WO091111368), and contains a carrying set comprising an improved carrying handle which can work in cooperation with some accessories as retaining cable sets, special padding, a bottle carrier

BACKGROUND ART

Some hand carrying tools are known having a central handle and a connecting apparatus at each end for carrying plastic shopping containers.

In some of these carrying tools the handles are made lighter by means of lateral longitudinal recesses. The longitudinal recesses create empty zones, which are not comfortable for the hands.

Such a tool is disclosed in Stoft (WO9111 1368), of which the present application is an improvement. In Stoft a surface 60 is described as “writing surface” which can be attached either on the flat inner surface of a longitudinal recess, either on the external surface of an other embodiment of said handle, having no recess. Pointing attention upon the embodiment without recesses, if said “writing surface” should be a surface supported by a thick body, if attached to such a handle without recesses, should cause serious trouble to the hand of a user. That means that said “writing surface” is an attached surface supported by a very thin body as a sheet, useful only to being written upon. The same “writing surface”, if attached to the embodiment having recesses, should keep the same features, and cannot be intended as a stopper filling said recess so as to eliminate the empty zones, which are not comfortable for the hands. Said writing surface has no mechanical resistance for performing the further feature of keeping in place a padding, (which instead is a feature of the present invention). Further, the connecting apparatus of Sotft is based on the existence of an enclosing segment that contours a rigid stepped down protrusion and does not provide accessories to obtain a carrying set.

Handles having generally hook-shaped connecting apparatus at each end are also known, and are provided with thin passages which prevent the shopping containers from being disengaged when put down.

This means that:

• • The user must pay attention to place the shopping container handles in the thin passage.
  • At the moment of disconnection the user must extract the shopping container handles from the thin passage using both hands. In this cases the user, if in a hurry, can lose time in connecting or disconnecting.
  • said handles can carry only objects having a very thin hookable portion, as plastic shoppers.

In some known handles (Clark, GB2218901A) there is a recess at each end which opens upwardly, provided with only one horizontal resilient retainer which, when removed, leaves only a thin passage. This has the drawback that the unraveling of thin strings cannot be prevented by this type of hooking apparatus.

In some other cases the thin passage is completely closed (Ducruox, FR 201950561 A), but a two-hands maneuver is necessary for disengaging the load.

In some other handles mechanical parts are present which require a double “two-hands” maneuver.

SUMMARY OF THE INVENTION

Accordingly, it is an object: of the present invention to provide a carrying set using a handle for carrying objects which is comfortable, in which the engagement and disengagement with the objects is easy and able to connect also some accessories able to connect particular objects.

It is another object of the present invention to provide a handle for carrying objects in which padding can be easily added, replaced or removed.

It is a further object of the present invention to provide a handle for carrying objects in which a removable surface is provided, which can be written or printed on.

These and further objects are achieved by the handle according to the attached claims.

DETAILED DESCRIPTION OF THE INVENTION

The present invention broadly comprises carrying set with an accessorized handle for carrying objects (or connecting handle or carrying handle or hooking handle) which is operatively arranged to be connectable to objects by connecting apparatuses at each end of the handle, as shown in the embodiments 1A, 1B, 1C, 1D of FIGS. 1,5,9,22,6.

In the preferred embodiment 1B (shown in FIGS. 5,10,11,14) the handle has at is ends two connecting apparatuses, one being the mirror image of the other one. Each connecting apparatus is able to

• • 1) hook and hold the weight of a load (carrying feature)
  • 2) retaining the hooked parts of a hooked object also when abandoned (closure feature)

The two features are performed by different members;

• • 1) carrying feature is performed by a hook shaped member internal to the apparatus (internal hook shaped protrusion 29,)
  • 2) closure feature is performed by the cooperation of two elastic opposite elements that work as adjacent elastic doors (flexible tongue 4 and lower elastic protrusion 15a).

This double elastic closure has two effects:

• • a) It permits to keep close the two sides of the closure
  • b) It permits a relevant opening space of said closure when opened, in which can be introduced wide objects, such as ropes, (FIG. 23).
  • c) It gives a very easy maneuver for insertion of the parts of objects to be hooked and carried: it can be done by simply pulling upwards the handle against the part to be inserted (FIG. 10).
  • d) It gives a very easy maneuver for the extraction of the hooked parts of the carried objects: simply pulling away the handle in the releasing direction (FIG. 11) can do it.

The handle is made padding able (FIGS. 6,7,12,13) by the existence of a front and rear longitudinal recess 56, in which a complementary-shaped element or elongated lateral element or stopper 19 can be forced. The stopper 19 keeps flat padding 28 in place, it can be printed for advertising or have an additional writing surface attached.

Another kind of padding disclosed is the tubular padding of FIGS. 14,15.

The performances of the connecting handle can be powered by the use of accessories.

A hookable sliding cable set 32, shown in the embodiments of FIGS. 16,17,18,19, 21-25, which permits the handle to connecting:

• • a) Objects having no hooking zone.
  • b) A plurality of objects.
  • c) A ski pair.

Further accessory is a strap shaped element useful for the carrying of a bottle set, shown FIGS. 27,28,29, while in FIG. 30 is shown a second method for the carrying of a bottle set.

Adverting now to the drawings:

FIG. 1 shows indicated as 1A, a connecting handle having a closure formed in cooperation by two opposite members:

The handle has a central portion 1 having two sides and two ends 17,18, having a face 17c having a lower part 17a and an upper part 17b, having a hooking apparatus 2 which is formed by two opposite ends of two protrusions (Upper protrusion or flexible tongue 4, lower protrusion 13)

The hooking apparatus 2 has a closure that works thanks to the cooperation of two opposite flexible members

• • a) elongated flexible tongue 4 protruding from upper part 17b and having a tongue end 4a, slightly curved downwards for helping insertions.
  • b) A lower protrusion 13 composed by a substantially horizontal corbel 10 protruding from lower part 17a and curving upwardly in a flexible element 15 having a thin portion 25 and an upper thickened ending 12, having a downwards inclined surface,6 standing close and opposite to tongue end 4a.

Therefore, when a hookable part of an object, (such as the straps 51 of a shopper 50, as shown in FIGS. 10,11 for handle 1B) is pushed inwards to the closure, both flexible tongue 4 and flexible element 15 begin flexing and tongue end 4a and inclined surface 6 are moved in opposite directions. This permits t to introduce the object. After introduction elasticity brings end 4a and surface 6 again close to each other, to retain the object.

The carrying feature is performed by lower protrusion 13.

Lower zone 7 of central portion 1 is hand-shaped; central zone 16 is a zone formed between parts 7, 14, so as to form, at each front/rear side, a longitudinal recess 56 in which an elongated lateral element or stopper 19 is forced in a position that locates its external surface or external side or external face 5 substantially at the same level of the edges 26 and 27 of lower zone 7 and of upper zone 14. A writing surface 60 can be attached on the external surface 5 of stopper 19.

FIG. 2 shows front view of lateral element or stopper 19 with attached writing surface 60, showing a detail of its lateral part 9 rearly protruding from the edge 5a of its external surface 5.

FIG. 3 shows the rear view of stopper 19, in which its rear face 5b has two protrusions 21 each having groove joints 20, to be connected to tongue joints 24, shown in FIGS. 4,5,7.

Front outline 5a of external surface 5 of stopper 19 protrudes rearly to form rear perimeter 22 and generates lateral part 9 of stopper 19

Obviously this type of joint is an example, as any known type of joint could be used to hold the stopper in place.

FIG. 4 is a cross-sectional view of handle 1A, and shows insertion of stoppers 19 with attached writing surface 60 in longitudinal recess 56. Rear protrusion 21 (protruding from rear face 5b of stopper 19) has groove joint 20.

FIG. 4 a is a cross-sectional view of handle 1A, wherein stoppers have tongue joints 21.

FIG. 5 shows indicated as 1B, a connecting handle which can be considered as a handle 1A wherein there is an internal hook shaped protrusion 29 extending upwards from the upper part of the end of said corbel 10 (which becomes a double ended corbel 10a). From le lower part of corbel 10a protrude flexible element 15a

This permits to give to flexible element 15a a longer and thinner thin portion 25a than in precedent case (thin portion 25 of FIG. 1), which increases flexibility, and thus the dimension of space 11 generated during insertion and extraction maneuvers, and thus reduces maneuver efforts (as shown in FIGS. 10,11).

Therefore the hooking feature is performed by hook shaped protrusion 29, while closure feature is performed by the cooperation between flexible tongue 4 and flexible element 15a.

A distance 23 permits free flexing of element 15a

Lower zone 7 of the handle is hand shaped. In the figure stopper 19 has not been shown for better show the position of protrusions 24.

FIG. 6 shows handle 1D having a flat padding 28 kept in place, partially entering in longitudinal recess 56 that has a stepped down lower surface 30 in its lateral inner surface 48. This permits to increase the space between surface 30 and lateral surface 9 of stopper 19, and therefore to increase the thickness of the padding.

FIG. 7 is a cross-sectional view of FIG. 6 and shows the detail of how padding 28 is kept in place over the lower zone 7 of handle 1D. The padding has holes (49, see FIGS. 12,13) complementary shaped to fit into protrusions 24

FIG. 8 illustrates that stoppers 19 can be disposed all together for printing, since external side 5 is parallel to the opposite rear perimeter 22 of stopper 19. Therefore indicia for advertising can be either printed on surface 5 with one only movement upon several stoppers 19 adjacently positioned, either added upon writing surface 60 before attaching it on surface 5 of stopper 19. The shape of stoppers 19, for the following of the design of the handle needs that a plane containing said external side 5 of said stopper and a plane containing a surface of said lateral part 9 of said stopper form an oblique angle,

FIG. 9 shows the hand 52 of a user holding a connecting handle 1B connected to the handles 51 of a plastic shopper 50.

FIG. 10 shows that the handle 51 of plastic shopper 50 can be inserted in the connecting apparatus 3 of connecting handle 1B simply by pulling upwards the connecting handle 1B in hooking position. That movement produces the opening in the closure as shown. In fact the pushing of the bag strap between surface 6 and tongue 4 causes the flexing of both members 4,15a, and therefore end 4a and surface 6 move in opposite direction and a passage 11 is generated.

FIG. 11 shows that the handle 51 of plastic shopper 50 can be disconnected by in the connecting apparatus 3 of connecting handle 1B by simply pulling upwards the plastic bag.

That movement produces the opening in the closure as shown

FIG. 12 Shows a plane embodiment of the padding 28 of FIG. 6

FIG. 13. Shows an embodiment of the padding 28 of FIG. 6 that is complementary shaped to the handle.

FIGS. 14,15 Show a tubular padding 28b for a handle 1B. This padding is built in foamy elastic material and in threaded upon the handle, therefore taking its shape

FIG. 16 shows an additional hookable sliding cable set 32 which permits to connect to the handle objects having no hooking zone or else a plurality of objects, which can be kept tightened all together also before and after the carrying. Cable set 32 comprises a loop shaped cable 39 threaded through a sliding stopper 35. Two loops are so formed:

• • a) An upper loop 37, above stopper 35, useful to be connected to the handle.
  • b) A lower loop 33, under stopper 35, which can give way to a sliding loop 34 if the end 33a of lower loop 33 (or sliding end 33) is inserted into the beginning 33b of loop 33, beginning that is the portion immediately under stopper 35.

Stopper 35 works as an obstacle against the sliding of end 33a in a loosing direction. This generates a method for easily wrapping objects and keep them tight, having the possibility of hooking them.

By wrapping the inserted load 62 in sliding loop 34, the user can keep it tight by pushing stopper 35 against end 33a. This action makes larger the upper loop 37, which can be hooked by a hooking tool.

FIG. 17 shows a ring cable set 32a wherein in loop 37 a ring 40 has been inserted, performing the additional function to prevent an undesired removal of the stopper 35, when maneuvered in releasing direction.

FIG. 18 shows an electric wire 56 kept tight by a cable set 32.

FIG. 19 shows a group of encumbering objects (a chair 54, first 53 and second 55 piece of a big shore umbrella) kept tight by two cable sets 32 and hooked to connecting handle 1B.

FIG. 20 shows two users 57,57a moving a sofa 59 by using two connecting handles 1B connected by ropes 60,61 passed under sofa 59.

FIG. 21, 22 show a handle 1C wherein the connecting apparatus consists of two ring-shaped bodies 84,84a located at each end of the handle to be connected by snap hooks 86 of cable set 32c or 32d. This handle is particularly useful to the carrying of skis, in cooperation with special cable sets 32c or 32d that are able to tight skis and to remain blocked on them. For the use of skis often includes rough situations, it has been seen that a hooking handle could in some situations get detached, while the connection between a ring shaped body and a snap hook can better resist.

FIG. 23 shows an embodiment 32c of a ski holding cable set similar to cable set 32 of FIG. 16, but further comprising a snap hook 86a and one elongated friction blocking element 70. Snap hook 86a threads cable 39 in correspondence of upper loop 37 and has a ring 86a or a hole that permits this threading. Elongated friction blocking element 70 has two ends and first 71a of said two ends is engaged to said beginning 33b of said lower loop 33.

This is possible because friction element 70 is a tubular element threading a loop shaped cable 72 coming out from first end 71a in shape of a loop and engaging beginning 33b, and coming out from second end 71b of friction element 70 connected to a knot 73 (or to an equivalent obstacle to the sliding inwards to the tubular element).

It so is possible to keep a ski pair blocked in said sliding set 32c thanks to the fact that the friction element 70 is compressed and blocked between skis when said skis 92,93 tightened by said sliding set. This prevents the sliding of cable set 32c in length direction, which is the problem of any ski holder.

FIG. 24 shows a second embodiment 32 d of a ski holding cable set. It differs from set 32c because the friction element 70a cannot move downwards when cable set extending t free (FIG. 26), and because it has a elongated handy part 75 for better maneuver the cable set 32d. Friction element 70a is kept in place close to the beginning of lower loop 33 because lower loop 33 is divided in two retaining areas 78,78a by retainer 77. Loop 72 of friction element 70a engages area 78 and keeps in place friction element 70a. Loop 72 of friction element has connector 74 that secures end 75a of elongated handy element 75. This makes possible an easier maneuver for the insertion/extraction of friction element from its position between skis.

FIG. 25 is a cross sectional view of a ski pair blocked in cable set 32d

FIGS. 27, 28, 29 show how it is possible the carrying of a bottle set 64 by the use of a simple strap shaped element 63 used for the carrying of a bottle set 64 in cooperation with a carrying handle 1B.

Strap shaped element 63 has two ends 67,67a and a ring shaped element 66,66a at each end.

It so is possible to include said strap shaped element 63 in the space 68 between bottle set 64 and its handle 65 and then to connect each of ring shaped elements 66,66a to each of ends 3,3a of carrying handle 1B. Bottle set 64 is so connected to carrying handle 1B thanks to strap shaped element 63.

FIGS. 30,31 show a method for packaging and the carrying of a package The method consists in providing the package with two ring shaped elements. In this example the package is epresented by a bottle set 64a, useful when the weight of is relevant. Bottle set is packaged wrapped in a flexible element 64b in which are threaded two ring shaped bodies 64c, 64d, useful to be hooked by carrying handle 1B

All elements of the carrying set disclosed can be built in plastic material, such as Nylon and the like, permitting the production of very inexpensive carrying tools having great utility.

Having described the invention and its advantages, one can see that it is based on the use of several parts and that each part can have different embodiments and be used in different combinations. This gives to this new carrying equipment a great extent of uses, of which the devices described in the figures are only some examples. Accordingly, the scope of the invention should be determined not only by the embodiments illustrated, but by the appended claims and their legal equivalents.
