Description

Trolley

Field of the Invention

invention relates to a trolley; in particular to a shopping trolley assembly.

Background of the Invention

Use of plastic bags for supermarket shopping is discouraged due to environmental issues aix! many shops now require customers to purchase bags. Custonicrs arc encouraged to re-use bags and provide their own bags to carry supermarket shopping.

A number of prior art docwnents describe bags that are arranged to fit into or onto supermarket trolleys. One such invention is described in US2004/0208397 (Chong-Kuk). This document describes a bag that includes a fixing frame, which is used to suspend the bag inside a conventional shopping cart by attaching the fixing frame to the upper side frames of the trolley.

This is said to overcome the problem of a customer having to transfer items from the cart into a bag or car one by one. Instead, the items are placed in the bag while shopping and when finished, tile shopping hag is vertically lifted up from the cart.

Other prior art documents describe trolleys that are adapted to hold one or more receptacles.

WO/0074996 (Mirrilees) discloses a trolley assembly including a foldable frame. The frame comprises two generally rectangular tiers, onto which semi-rigid receptacles are held by lugs on the receptacles. In another embodiment, tile receptacles may be used like conventional shopping bags which are flexible and include carry straps. In this embodiment the receptacles are supported in seats in the trolley frame. Two rods are threaded through seams in the bags and the ends of the rods are seated in the seats.

There are a number of disadvantages associated with prior art trolleys and bags. For example, they do not address the problem of loading and unloading of the trolley or storage of trolleys.

It would therefore be desirable to provide an improved trolley.

Detailed Description of the Preferred Embodiments

As illustrated in Figures 1 and 2, a trolley I comprises a frame 2 defIning at interior space 2(1.

In a preferred embodiment, the trolley has four wheels 3, one of which indudes a brake.

in a preferred embodiment, the frame 2 is made from tubular steel.

The trolley 1 has a front end 9 and a rear end 10. The width of the trolley I is greater at the rear end 10 than at the front end 9.

The frame 2 comprises a main frame both 8. The main frame body 8 includes a handle section 4, which is integral with two substantially vertical sections 5 and a base section 6.

The handle section 4 may be adapted to allow a child seat to be mounted on the frame 2.

Two side sections 7 of the frame 2 are welded to the main frame body 8. Because of the tapering width of the trolley I from the rear end 1) to the front end 9, the side members are spaced closer together at the front end 9 than at the rear end 1).

At the front end 9 of the trolley the space between the two side sections 7 provides an open front end 21 of the trolley I. The trolley 1 may further include supports 12 extending between sections of the frame 2 for added strength and stability. One or more panels 19, may be included in the frame 2. The panels have a surface area to which advertising may be applied and they also help to restrict movement of bags and/or items held in the bags, in the interior space 20.

The space between the substantially vertical sections 5 and the tapered arrangement of the trolley I allows nesting of several trolleys together. Support 12' also acts as a guide bar to aid in nesting of trolleys together. Support 12" also acts as a stop to prevent jamming of nested trolleys.

As illustrated in more detail in Figure 3, the frame 2 further comprises substantially parallel support members II. in a preferred embodiment the support members 11 have a flat upper surface I Ia and a flat inner surface 1 lb. The support members 11 include receiving elements 13 in the surface 11, which in a preferred embodiment, are grooves or indents.

The receiving elements 13 are shaped to receive rods 1 4. The rods 14 are preferably made from nylon and are sized such that each rod 14 fits inside a loop 15 in a bag 16. In a preferred embodiment the rods 14 are around 530mm in length and have a diameter of around 20mm.

The ends I 4a of the rods 14 fit into receiving elements 13 and support the bags 16 in the trolley 2, as shown in Figures 3 and 4.

In an alternative embodiment, hooks or other fasteners mas' be attached to the ends of the rods, which may hook on to a support member to suspend the bags on the trolley.

Washers 17, which may he nylon washers, are attached at the ends of each rod 14. The washers 17 prevent the bag 16 from sliding on the rod 14 and also prevent the rod 16 from sliding in the receiving elements 13. When a hag 16 is suspended in the trolley 1, the washers 17 rest against the inner surface 11 b of each support member Il. The end 14a of each rod 14 extends beyond the support member 11.

Figure 5 shows a bag 16 with loops 15 at two sides of the upper surface.

The bags 16 have handles 18 on each side so that they can be used like convenuonal shopping bags.

In a preferred embodiment the bags are foldable bags made of a hardwearing, biodegradable material with a reinforced base for strength.

It is envisaged that the bags will be purchased by a customer or given free to a customer. A customer can then store them in the boot of a car to be re-used and loaded into a trolley 1, on each shopping trip.

Different sizes of bags 16 may be suitable for use with the trolley 1. In a preferred embodiment the bags are around St k)m,n in length, 3t)Omm in width and between 400-óUUimn in height.

In one embodiment, the bags 18 may extend down close to the base section 6 of the frame 2.

The trolley has a large capacity and is capable of holding the same amount of items as a conventional shopping trolley.

The trolley 4 is preferably arranged to receive four bags, but alternative embodiments holding different numbers of bags are envisaged. Four bags is the optimum number since fewer bags results in heavier loads in each bag. In an alternative embodiment, the receptacles mai-be something other than bags, for example niore rigid structures, such as boxes.

At the beginning of a shopping trip, the re-usable bags 16 are positioned in the trolley such that the ends I 4a of the rods 14 are located in receiving elements 13 on the trolley 1.

Items are placed in the bags 16 during shopping and after payment at a checkout, the bags are unloaded from the trolley 1 at the end of the shopping trip.

To unload the bags 16 from the trolley 1, a user may lift the bags 16 vertically from the trolley 1 using the handles 18. However, if the bags 16 are filled with shopping items, they may be quite heavy.

Using the trolley I, it is only necessary for a user to lift each hag 16 vertically from the trolley I by a very small distance, corresponding to the depth of the receiving element 13, which, in a preferred embodiment, has a depth of 22niiii.

The ends of the rods I 4a may then be rested on the tippet surface II a of the support member 11 and may he slid along tile support member 11 and out of the interior space 2) through the open front end 21 of the trolley 1. In this way the support member 11 supports the weight of the bags 16 when unloading them from the trolley and it is not necessary to lift a bag 16 vertically over the sides of the trolley.

Sliding of the bags 16 out of the trolley is facilitated by the washers 17, which act as guides along the inner surface 1 lb of the support member Ii during sliding. It is also made easier since the rods 14 are free to rotate inside the loops 15 of the bags.

The support members 11 may be lower at the front end 9 of the trolley I than at the rear end 1), so the bags I 6 ma' he slid along the support member 11 in a downwards motion towards the front end 9 of the trolley. The frame 2 and/or the support member 11 may have a rounded edge at the front end 9 of the trolley to assist in sliding bags 16 from the trolley.

In an alternative embodiment, the bags 16 may be slid along the support member 11 towards the rear end 10 of the trolley I and removed from an open rear end of the trolley.

11w trolley I has a number of advantages over prior art trolleys. The invention is environmentally friendly since there is no need fc,r conventional plastic carrier bags and the trolley itself uses minimum amount of material. This also makes the trolley inexpensive to make and easy to manufacture.

The bags remain upright in the back of a car and are easier to carry than conventional plastic shopping bags.

Unloading of the trolley is made easier by having an open front end and a support surface for sliding out bags with items of shopping in them. Nesting of trolleys is improved as the trolley also has an open rear end and tapered frame structure.

Tn another embodiment of the invention, one or both of the support members 11 may be slidable with respect the rest of the frame 2. To unload the trolley 1, the support members ii with the bags 16 suspended thereon, may slide out from the frame 2 and be unloaded from outside of the internal space 2() of the trolley. In this case an additional wheel 3 may be added to the frame at the front 9 of the trolley 10 and connected to the support members I I to support their weight as they are slid out from the frame 2.
