Lid with a handle for containers of accumulators

Abstract: The invention discloses the realization of a lid 2 equipped with a handle 3 for containers of accumulators, comprising in combination an essentially flat surface 21 which constitutes the upper part of the raising 6 of the lid 2 and which presents at least one couple of openings. Each opening has in its inner part at least one projecting grip pawl 12 and at least one elastic handle 3, the latter presenting at least one projecting tooth 10 in its ends 4. The central body 9 of the handle 3 is entirely lodged inside a housing 8 made in the raising 6 and each end 4 is coupled within at least one of the openings 5 which are situated in the raising 6. When the handle is lifted, its projecting teeth 10 engage in the corresponding projecting grip pawls 12 of the lid, thereby allowing the accumulator to which the lid is connected to be lifted.

Description: It is known that the lifting and the transport of accumulators are difficult to perform, both because of their considerable weight and because the accumulators are generally situated in narrow and not very accessible places, particularly the startup accumulators. Certains makers have solved this problem by installing one or more handles on the accumulator lids. Said handles make both the extraction of the accumulator from its housing and the transport easier. A constructive solution particularly suited for small accumulators is known, according to which the handle is composed of a U-shaped element, preferably made of plastic material and connected to the lid by means of pivots. Said handle can rotate around the pivot axis and, when it is at rest in a horizontal position, it completely circumscribes the raising made in the upper part of the lid, where the topping up caps are placed so that the handle does not project over the upper surface of the lid. As far as greater accumulators are concerned, two handles of the afore-mentioned type are installed; each handle is pivoted to the lid and is placed transversally to the alignment axis of the topping up caps. In such a case, when the two handles are at rest in a horizontal position, they too circumscribe the raising which is made in the upper part of the lid where the topping up caps are placed in such a way that, in this case too, the handles do not project over the upper surface of the lid. The US-A-4 632 888 discloses a recessible carrying handle for batteries. wherein the handle is attached to the container after the assembling of the lid with the container of the battery. The handles of the described type present some disadvantages. The first disadvantage is their high realization and assembly costs, the latter being due to the difficulty of the assembly. Another disadvantage of the handles of the known type is that it is difficult to lift them in a position suited for the transport of the accumulator. This is due to the smooth surface of the handles. which are difficult to grip. Another disadvantage, which one encounters when two handles are applied to the accumulator lid, is that a recessing in which to place the handles is necessary for the handles not to project over the upper part of the lid when they are at rest in a horizontal position; the recessing is placed in an essentially central position and is transverse to the alignment axis of the topping up caps. This implies the interruption of the gas discharging horizontal duct which transversally connects all the topping up caps, which do not communicate with each other, so that two transverse ducts are necessary, each duct connecting the topping up caps placed at the sides of the transverse recessing where the handles are lodged. The purpose of the invention is the realization of a lid equipped with a handle for containers of accumulators, which overcomes the afore-mentioned disadvantages. More in detail, the purpose of the present invention is the realization of a lid equipped with a handle characterized by a low realization cost and by the fact that the assembly of the handle to the lid is quick, easy and cheap. Another purpose of the invention is the realization of a lid equipped with a handle, the latter being characterized in that it does not project over the upper surface of the lid when the handle is at rest in a horizontal position, and is lodged inside a recessing made in the lid; the recessing does not break the continuity of the gas discharging horizontal duct which transversally connects all the topping up caps. Another purpose of the invention is the realization of a lid equipped with a handle, the latter being easy to lift and grasp. Not the least purpose of the invention is the realization of a lid equipped with a handle, whereby said handle automatically goes back inside the housing in which it lies at rest after being released. The above-mentioned purposes and others which will be better understood hereafter are reached by the realization of a lid equipped with a handle for containers of accumulators the main features of which are according to claim 1. According to a preferred embodiment of the invention, the housing in which the handle is lodged presents a raised surface which is far from the flat surface of the upper part of the lid raising of a distance which corresponds to the thickness of the handle. Thus, when the handle is at rest inside its housing, it does not project from the upper plane of the lid, so that the piling up of the accumulators is not jeopardized. The handle is preferably made of flexible plastic material with a low thickness. Advantageously, a lid according to the invention is realized equipped with a handle which is cheap, easy to assembly and to lift from its housing. Moreover, advantageously, the handle is easy to grasp and it automatically goes back inside its housing after being released. The above-mentioned purposes and advantages will became apparent from the description of a preferred form of embodiment, which is given by way of illustration only. Fig. 1 shows a plan view of the lid equipped with a handle according to the invention; Fig. 2 shows a cross section of the lid equipped with a handle according to the invention being at rest in a horizontal position. Fig. 3 shows a cross section of the lid equipped with a handle according to Fig. 2, said handle being lifted in the same position as when the accumulator is to be transported. As can be seen in Fig. 1, the invention indicated as a whole with 1, is composed of a lid 2 which is parallel to the alignment axis of the topping up caps 7. A handle 3 is applied to the lid, and each end 4 of the handle is inserted into a horizontal opening 5, which can be seen in Fig.s 2 and 3 and which passes in the raising 6 of the lid, where the topping up caps are placed. The two lateral openings 5 are coaxial and in connection with a housing 8; said housing is made in the raising 6 of the lid 2, is parallel to the alignment axis of the topping up caps 7 and contains the whole body 9 of the handle, when the latter is at rest in a horizontal position. It is understood that the housing does not break the continuity of the gas discharging transverse duct 31 which connects the topping up caps. It must be specified, however, that according to a particular embodiment, it is possible to apply more than one handle. In addition to this, according to a specific embodiment of the invention which can be applied either to lids for small accumulators or to lids which do not have topping up caps connected to each other by means of the gas discharging transverse duct 31, the handle can be put transversally to the alignment axis of the topping up caps 7. As can be seen in Fig.s 2 and 3, each end 4 of the handle presents a projecting tooth 10 and an angle-shaped ledge 11, while each opening 5 in which each end 4 of the handle 3 is inserted presents a projecting grip pawl 12. While the angle-shaped parts 11 are used for centring the body 9 of the handle within the housing 8 when the handle is at rest in a horizontal position as can be seen in Fig. 2, the projecting grip pawls 12 and the projecting teeth 10, made respectively in the opening 5 and in the ends 4 of the handle, are used for lifting the accumulator 13 which is coupled with the lid 2 when the body 9 of the handle is lifted by applying a vertical force 14. In particular, it can be noted that in the lower part of each end 4, the handle 3 presents a protuberance 15 which is used for keeping the ends 4 of the handle raised over the lower plane 20 of the raising 6 on which the ends 4 lean, so as to keep the projecting grip pawls 12 and the projecting teeth 10 always aligned in the hooking direction. Moreover, the body 9 of the handle keeps aligned with the upper surface 21 of the raising 6, since the housing 8 presents its surface 30 raised over the lower plane 20, which acts as stop and bearing of the body 9 of the handle 3. The insertion of the handle 3 in the lid 2 is possible by placing the handle as shown in Fig. 3 and forcing its ends 4 toward the direction indicated by the arrows 16, so as to make each end penetrate into the corresponding opening 5. In order to do this, it is enough that the force applied in the direction 16 is such that it wins the elastic resistance of each protuberance 15 against the plane 20. When both ends 4 are inside the openings 5, the handle 3 is released, it lowers down on the plane 30 and assumes the horizontal position which is shown in Fig. 2. To raise the handle, it is enough to apply a horizontal force in the direction 17 on one of the ends 4 of the handle, as can be seen in Fig. 2, so that the handle assumes the position shown in Fig. 3, both because of its elasticity and because its angle-shaped ledge 11 bucks with the edge of the opening 5 which is opposite to the direction of the force 17. At this point, the handle is easy to grasp and the accumulator can be easily lifted. According to what has been said, it is understood that the lid equipped with a handle according to the invention fulfills all mentioned purposes. First of all, the purpose of obtaining a lid equipped with a handle which is easy to realize, cheap and easy to assemble, is reached. As far as the openings 5 made on the lid are concerned, it is understood how they can easily be realized by opportunely shaping the mould with which the lid is realized and, likewise, it is understood that the handle 3, with the same shape as that represented in the described figures, is easy to realize. According to what has been described, it has also been seen how the application of the handle 3 is easy and can be manually made, without the need of facilities. It has also been seen how, in case the topping up caps 7 of the lid are connected to each other by means of a gas discharging transverse duct, the latter is one and the same for all the topping up caps, since the housing of the handle is parallel to the alignment axis of the topping up caps. It has also been seen that, given the shape of the handle ends, the handle 3 can be easily lifted and grasped; moreover, given the elasticity of the handle, it automatically goes back into the housing 8 when it is released. Lastly, since it has been seen that, when the handle 3 is at rest, it does not project over the upper surface 21 of the lid, the accumulators which are equipped with the lid according to the invention can be easily piled up. During the manufacturing process, various changes and modifications can be made on the lid equipped with a handle according with the invention. It has also been seen that, as for lids of small accumulators and for lids which do not have topping up caps which are connected to each other by means of the gas discharging transverse duct 31, the handle may also be placed transversally to the alignment axis of the topping up caps. Moreover, the projecting teeth 10 and the projecting grip pawls 12 can be made respectively in the ends 4 of the handle and in the openings 5 in which each end 4 is inserted, no matter what the shape is and how many they are. Furthermore, the handle 3, which is preferably made of elastic plastic material, can also be made of other materials. In addition, the handles can also be more than one. It is, however, understood that all the above-mentioned changes and variations will be included within the scope of the present invention.
