Description:TECHNICAL FIELD
The present subject matter relates to a load handling assembly having a load handling device and an energy storage system employing a handling device.

BACKGROUND
Conventionally, various types of load handling devices such as ropes, handles and/or straps of various materials are used for handling loads of various types such as mechanical loads (small machine equipment, bags, suitcases etc.), electric loads, electronic loads and other types of loads. Such items are used for carrying, lifting, moving, adjusting and/or otherwise handling such loads. However, use of such conventional load handling devices involves several disadvantages, particularly, involving wear and tear, unreliability, poor fitting, discomfort, poor performance and poor ergonomics among others.
Loads like energy storage device and other electronic loads may be used in many applications like power converters, vehicles, power stations, and factories etc. where there may be requirement of frequent replacement or change or repair/maintenance of such systems. Currently, energy storage systems are also in high demand due to rise in popularity of electric vehicles. Such energy storage systems are also necessary in conventional internal combustion engines. These loads and their correct handling are necessary for proper functioning of the equipment. For example, in order to save time and add convenience for the user, can simply be swapped for replacement in case the battery gets discharged. Further, the device may also require servicing or repair. Thus, said energy storage systems need to be removed, carried, reinstalled, repaired or replaced. Particularly, sensitive loads like electric or electronic loads may get damaged or cause injury to persons or equipment involved in handling such loads in case of breakage or poor handling performance or poor capabilities of said conventional devices. This is especially true for applications like vehicles where use of such loads have space constraints. Load handling devices in the conventional art also take up more space around the load which is not desirable for said compact configurations. Therefore, in order to carry, lift, move, adjust and/or otherwise handle such loads, there is a need of a suitable load handling means/ assembly which is easy to use, reliable, having a high performance and ergonomically efficient. Further, repeated use of the load handling device also leads to wear and tear.
The above disadvantages can pose risk for the respective loads being handled by such devices and cause damage or injury. This may also cause difficulty in fitting these loads and difficulty in removal and installing them in case there is any such requirement. Lastly, such known load handling devices also take up more space around the load which is not desirable for compact configurations. It is further desirable that when such load handling devices installed on loads be retractable after shifting and/or lifting of the load.
Hence, there exists a challenge of designing a secure load handling assembly for efficient handling of loads like energy storage device and other electronic loads. This is particularly true for compact installations for example a vehicle. The challenge is also for ensuring the safety and ease of assembly to the user without any major change in layout design and manufacturing set-up of the installation like a vehicle. It is further desirable that when such load handling devices installed on loads be retractable after shifting and/or lifting of the load so that they do not take up extra space when not in use.
The present invention provides a solution to the above problems while meeting the requirements of minimum modifications in vehicle, at moderate cost with ease of assembly and maintaining the efficient ergonomics of the load handling assembly etc.

The present subject matter is further described with reference to accompanying figures. It should be noted that the description and figures merely illustrate principles of the present subject matter. Various arrangements may be devised that, although not explicitly described or shown herein, encompass the principles of the present subject matter. With reference to the accompanying figures, the same reference numerals will be used to identify the same or similar elements throughout the several views. Moreover, all statements herein reciting principles, aspects, and examples of the present subject matter, as well as specific examples thereof, are intended to encompass equivalents thereof.
Fig.1 is a perspective view of a load handling assembly (300) comprising a load (200) and Fig.2 is perspective view of the same arrangement (of Fig.1) from different angle of the the load handling assembly. The load (200) can be an energy storage system providing energy for the functioning of another equipment/device/machine for example a multi-wheeled vehicle (not shown). The load handling assembly (300) further comprises at least one load handling device (310) which is detachably attached to the load (200). Figure 7 also explains one embodiment of the assembly (300) in exploded mode. In one embodiment of the assembly (300) there are two load handling devices (310) on the load (200).
Figures, 8a, 8b, 9a, 9b and 9c explain the load handling device (310) and its various components in more detail. Fig.8 (a) is a detailed perspective view of the load handling assembly as per embodiment of the present invention. The load handling device (310) has an elastic member (303) which has at least two ends. The said figures show the elastic member (303) with two sides. A pair of holding members (302a and 302b) is provided which have at least two sides. Each end of the elastic member (303) is connected to at least one side of each of the said holding members (302a and 302b). A grip member (301) is also provided which has at least two ends. The figures (Figure 8(a) and Figure 8(b) show a grip member (301) with two ends. Each end of the grip member (301) is connected to the other side of the said holding member (302a and 302b). Thus, the grip member (301), the holding members (302a, 302b) and the elastic member (303) form a close loop when installed on to the load (200) in the load handling assembly (300). The elastic member (303) is capable of stretching on application of force on its two ends and when the force ceases to be applied, the elastic member (303) contracts to its original size.

The front view of the energy storage system in the load handling assembly (300) is depicting the position of two parallel planes/cross sections XSEC0001 and XSCE0002. The right-side view of an energy storage system in the load handling assembly is depicting section XSEC0003 which is perpendicular to the XSEC0001 and XSCE0002. Figure 3 shows reference figures showing planes from where the cut section views in Figure 4 and 5 have been obtained. The cut sections across these planes are described hereinafter.
Fig.4 is a sectional side view of the load (200) with the load handling assembly (300) along section XSEC0001- XSEC0001 (also refer to Fig.3) as per embodiment of the present invention. Further, as per one embodiment of the present invention, a stopper means (201) comprises a guide way (202), a pair of first slots (203a and 203b) and a pair of second slots (204a and 204b). Each of said pair of slots has an upper slot (203a, 204a) and a lower slot (203b, 204b). In Fig.4, the sectional view is showing position of the grip member (301) entering into the upper slots (203a, 204a) and out of the two pairs of slots (203 and 204). Referring to Fig.2 and Fig.4, the grip member (301), the pair of holding members (302a and 302b) and the elastic member (303) is slidably mounted on the guide way (202). The holding members (302) and the elastic member (303) are substantially on the guide way (202), while a part of both ends of the grip member (301) passes through the pair of first slots (203a and 203b) and the pair of second slots (204a and 204b) and attaches to the other end of the holding members (302a and 302b) on the guide way (202). In this configuration, the elastic member (303) being positioned between the first and second pair of slots (203a, 203b, 204a and 204b) of the stopper means (201).
Fig.5 is also a sectional side view of the load (200) with the load handling assembly (300) across section XSEC0002 and a localized enlarged view as per embodiment of the present invention. Further, the sectional view (Fig.5) is showing the position of the grip member (301) coming out of the lower slots (203b, 204b) of the two pair of slots (203, 204).
Fig.6 is a sectional top view of the load with the load handling assembly (300) along section XSEC0003 as per embodiment of the present invention i.e. from the top of the load handling assembly (300). Further, the sectional view is showing the position of the grip member (301) coming out of the lower slots (203b, 204b). Further, this figure is also showing elastic member (303) and holding members (302) from a top view.
Fig.7 is a detailed perspective view of the load with the load handling assembly (300) as per embodiment of the present invention. In the figure a load/energy storage system (200) is shown along with two load handling devices (310) installed on two top sides of the load (200). The load handling device (310) comprises the grip member (301) which has at least two ends, a pair of holding members (302a and 302b) which have at least two sides. Each end of the grip member (301) is connected to at least one side of each of the holding members (302a and 302b). An elastic member (303) which also has at least two ends and each of the ends is connected to the other side of each of holding members (302a and 302b). Thus, the grip member (301), the holding members (302a, 302b) and the elastic member (303) form a close loop when installed on to the load (200) in the load handling assembly (300). The elastic member (303) is capable of stretching on application of force on its two ends and when the force ceases to be applied, the elastic member (303) contracts to its original size. Further, as per one embodiment of the present invention, a stopper means (201) comprises a guide way (202), a pair of first slots (203a and 203b) and a pair of second slots (204a and 204b). In Fig.7 the load handling device (310) comprising the grip member (301), holding members (302) and the elastic members (303) are shown in installed condition but demounted from the stopper means (201) i.e. demounted from the guide way 202 and the pairs of slots (203, 204).
Further, as per embodiment of the present invention, when at rest, the grip member 301 of the load handling device (310) is substantially aligned with the body and contours of the load. In Figure 1 and 2, it can be seen that upon installation of the load handling device (310), the grip member (301) is at rest and the body of the grip member (301) co-planar with the top surface of the load (200) so that the grip member (301) does not take up extra space beyond the contours of the load (200). When a user intends to lift, move or shift the load (200), a lifting or pulling force may be applied to the grip member (301) in the vertical direction away from the top of the load (200). Upon application of said force on the grip member (301) to lift the load (200), the pair of holding members (302a and 302b) stretch the elastic member (303) while moving along said guide way (202) in the directions of the opposite ends of the elastic member (303). This stretching enables a part of the grip member (301) to slide out of the pairs of slots on both sides and move away from the body of the load 200. This creates suitable space for the user to lift the load (200) without the hands interfering with the body of the load (200). However, the stretching of the elastic member (303) and the consequent movement of the holding members (302) in opposite directions is blocked by the presence of the first and second pairs of slots (203a, 203b, 204a and 204b). Further, as per embodiment of the present invention, in the load handling assembly (300), the holding members (302a and 302b) have a height H1, the guide way (202) has a width H2 wherein the width H2 is greater than height H1 to enable smooth motion of the holding member (302a and 302b) across the guide way (202) . Further, the first and second slots (203a, 203b, 204a and 204b) blocking the holding members (302a and 302b) have a height H3 wherein the height H3 of the slots is greater than height H1 and width H2 so that while the holding members (302a and 302b) move along with the guide way (202) due to stretching of the elastic member (303), the slots having height H3 can block the movement of the holding member (302).
Fig.9 (a) is a top view of the load handling assembly as per embodiment of the present invention.
Fig.9 (b) is a front view of the load handling assembly as per embodiment of the present invention.
Fig.9 (c) is a side view of the load handling assembly as per embodiment of the present invention.
Fig.10 is a perspective view, front view and side view of a holding member (302) of the load handling assembly (300) as per embodiment of the present invention. The height H1 of the holding members (302) is being shown in this Figure. This height H1 is smaller than the width H2 of the guide way shown in Figure 13. The height H1 of the holding member is also shown from a side perspective in Figure 9(c) where the holding member (302) is attached to the elastic member (303) and the grip member (301).
Fig.11 is a perspective view of a pair of holding members (302a and 302b) attached to the elastic member (303). When the loading device (310) is installed on the load (200) and a lifting force applied to the grip member (301), the elastic member (303) is stretched towards its ends (two ends shown in the figure) as the force is transferred from the grip member (301) to the elastic member (303) through the holding members (302). In a preferred embodiment, the elastic member (303) is made up of stretchable material like natural or synthetic rubber or any other suitable polymer with durable elastic properties that may be long lasting. In case of wear and tear or breakage due to prolonged usage and stretching of the elastic member (303), the entire load handling device (310) need not be replaced but only the elastic member (303) can be replaced thereby enhancing the life of the load handling device (310) and the assembly (300). This also leads to saved costs because replacing of entire load handling device (310) would be more costly. When the load (200) is in lifted condition, the holding members (302) carry a substantial part of the load and it is desirable for them to not get deformed in the process. Thus, it is preferred to have the holding members made of solid material like a metal or suitable alloys.
Fig.12 is a perspective view and top view of the grip member (301) with two ends, of the load handling assembly (300) as per embodiment of the present invention. It is preferred to have the shape of the grip member (301) to conform to the shape or contour of the load (200) whereupon said grip member (301) is installed. This way when in resting condition, the grip member (301) and consequently the load handling device (310) will not occupy extra space beyond the profile of the load (200) thereby saving space in vicinity of the load (200) where it is installed. In one embodiment, the grip member (301) may be made of suitable polymers like nylon or other polymer with medium density so that it can be rigid enough to conform to the contour and shape of the load (200) in resting position but also flexible enough for it to be installed through the pair of slots (203a, 203b, 204a and 204b). In one embodiment, the ends of the grip member (301) have suitable means in the form of loops or hooks for them to be attached to the holding members (302a and302b). In an alternative embodiment the grip member (301) is made of metal having the above said features.
Fig.13 is a perspective view of a cover (210) of the energy storage device/load (200). The said cover (210)comprises stopper means (201) further comprising guide way (202), a pair of first slots (203a and 203b) and a pair of second slots (204a and 204b). The figure shows the width H2 of the guide way (202) extending from one edge of the cover (210) to the other. In one embodiment the load in the load handling assembly (300) may only comprise the cover (210) of the energy storage device (310) Fig.14 is a perspective view of the load cover (210) comprising the stopper means (201) comprised of a guide way (202), a pair of first slots (203a and 203b) and a pair of second slots (204a and 204b). Figure 4 is also depicting the exploded view of one of the pair of slots 203a comprising an upper slot (203a and 204a) and a lower slot (203a and 204b).
Fig.15 is rear, side, top and front view of the load cover (210) as per embodiment of the present invention. In another embodiment the features of the above said cover (210) including the stopper means (201) including the guide way (202) and slots (203a, 203b, 204a and 204b) may be provided on a battery. In such case, the load (200) would comprise only the battery instead of the energy storage device (200). A skilled person can apply the teachings of the above disclosure and drawings, particularly Figures 13-15 on a mere battery or any other load such as power converters, control units, data storage devices, medical equipments etc. which require frequent handling, shifting and/or moving using load handling device (310).
Advantageously, the embodiments of the present invention, describes the potential modifications in a load handling assembly having a load handling device and a load/energy storage system employing a handling device. This facilitates the ease of carrying, lifting, moving, adjusting and/or otherwise handling such loads.
Many other improvements and modifications may be incorporated herein without deviating from the scope of the invention.
