This invention relates to trailers suitable for towing behind vehicles. Some embodiments provide lightweight tent trailers.
Camping is a popular pastime. Some people camp in large recreational vehicles that may have several well-appointed rooms. Some people camp in enclosed travel trailers which require a large tow vehicle such as a heavy duty pickup truck. While these vehicles have their places, there is an increasing interest in smaller, lighter, less expensive options. For example, camping trailers that can be safely towed behind compact cars are becoming popular in some circles.
Storage of trailers can be an issue. Many people do not have space to store even a small trailer in its standard horizontal position. Furthermore, small, light trailers may be stolen if left outside.
There remains a need for means of storing trailers in a compact manner.
This invention has a number of aspects. These aspects may be combined or applied separately. These aspects include, without limitation:
Further aspects and example embodiments are illustrated in the accompanying drawings and/or described in the following description.
The accompanying drawings illustrate non-limiting example embodiments of the invention.
Throughout the following description, specific details are set forth in order to provide a more thorough understanding of the invention. However, the invention may be practiced without these particulars. In other instances, well-known elements have not been shown or described in detail to avoid unnecessarily obscuring the invention. Accordingly, the specification and drawings are to be regarded in an illustrative, rather than a restrictive, sense.
Trailer 10 has a low profile so that it does not obstruct rearward view from the tow vehicle. The low profile may also reduce wind drag when trailer 10 is being towed. As described below, the low profile also facilitates compact storage of trailer 10. In some embodiments, trailer 10 has a height of less than about 4 feet (˜1.2 metres). In some embodiments, trailer 10 has a width of approximately 5.5 feet (˜1.7 metres).
In the illustrated embodiment, trailer 10 comprises a body 14 having a front end 14A and a rear end 14B. Trailer body 14 includes a shell 15 having a bottom part 15A and a top part 15B. Top part 15B may be opened to access the inside of shell 15. For example, top part 15B may be hinged to bottom part 15A, forming a clamshell arrangement as described in more detail below. Top part 15B may be locked to bottom part 15A by any suitable means (e.g. cam-type latch or the like) when the clamshell is closed. Shell 15 may be formed from a durable waterproof material such as a formed plastic, aluminum, or fiberglass, for example.
Trailer 10 includes wheels 16 mounted for rotation about an axis 16A. Even though trailer 10 may be much smaller and lighter than conventional travel trailers, it is necessary for the distance from hitch 12 to axis 16A to be long enough for trailer 10 to smoothly trail behind a tow vehicle. For example, the distance from hitch 12 to axis 16A may be such that the body 14 of trailer 10 does not contact the tow vehicle when the tow vehicle makes a 90° turn. It is also desirable for this distance to be long enough to facilitate control of the steering of trailer 10 when backing up the tow vehicle. Tongue 18 may, for example, project from front end 14A of body 14 by a distance in the range of about 3 to 6 feet (˜1 to 2 metres).
Wheels 16 may be supported in various ways. In the embodiment shown in
Storage
Trailer 10 has a number of features to facilitate storage. These include:
Tongue 18 may, for example, comprise a section of tubing that is received in a socket 17A in frame 17, as shown in
With tongue 18 removed, body 14 of trailer 10 may have a length that is less than 7.5 feet (˜2.15 metres) long. This allows body 14 to be stood vertically in a garage or other storage area having a ceiling having a height of 8 feet or more. Wiring (e.g. to the tail lights of trailer 10) may be clipped to tongue 18, and unclipped from tongue 18 when tongue 18 is removed. Some embodiments provide a wiring connector on body 14 that allows wiring for connection to a tow vehicle to be uncoupled from body 14 when it is desired to remove tongue 18.
As shown in
In some embodiments, the pivot point provided by hinge 20B is raised above part 20A, such that trailer 10 is tilted slightly backward (i.e. to the right in
Stand 20 may include a stop that prevents trailer 10 from tipping past its vertical storage configuration. In the illustrated embodiment, contact between parts 20A and 20D acts to provide a stop.
In some embodiments, the length of the portion of first part 20A between hinge 20B and end 20J is selected such that end 20J can be placed against the base of a wall and then trailer 10 can be tipped up to its vertical storage position. First part 20A spaces hinge 20B far enough far enough from the wall to permit trailer 10 to be moved to the vertical storage position while leaving trailer 10 close enough to the wall that space is not wasted. In some embodiments, first part 20A spaces the part of body 14 that is closest to the wall when trailer 10 is in the vertical storage position (i.e. top part 15B) about 6 inches (˜15 centimetres) or less away from the wall.
In some embodiments, two stands 20 may be provided, one on each side (i.e. left and right sides) of body 14. By providing two stands 20 which are the same length, abutting end 20J of each stand against a wall may ensure that trailer 10 is parallel to the wall when it is in the vertical storage position, again maximizing the available space.
In the example embodiment shown in
Stand 20 may comprise one or more parts. In a convenient implementation shown in
Rear end 14B of trailer 10 rests on member 20F which is attached to member 20D when trailer 10 is stored vertically with tongue 18 removed. Member 20F may be made of a soft material to cradle rear end 14B.
Member 20A (and in particular, end 20J of member 20A as shown in
As can be seen in
When stand 20 is attached to sockets 17C and 17D in the rear end 17B of frame 17, member 20D extends generally at right angles to a longitudinal axis 22 of trailer body 14, as shown in
The stability of trailer 10 when it is being stored vertically as shown in
Trailer body 14 may be light enough that one or two reasonably fit people can safely lift trailer body 14 into the vertical storage position shown in
While significant variations in the design, features, and layout of trailer 10 are possible, it can be appreciated that a trailer 10 having general design features as described herein is well-adapted for use by urban people who have small cars and limited storage space. Such a trailer may be stored at the end of a parking space in a carport or garage while leaving room to park a car.
When it is desired to use trailer 10, it is relatively quick and easy to reverse the steps shown in
In some alternative embodiments, stand 20 comprises an L-shaped member which preferably has a curved corner, as shown in
Tent
A tent 34 is attached to shell 15 and may be contained within shell 15 when shell 15 is closed. As shown in
Work Surface
Trailer 10 may include a tailgate that provides a swing out and/or removable work surface. A work surface may be provided together with some or all of the other features described herein or in a trailer which lacks those features.
Work station 70 is hinged on one side to shell 15 by a hinge 72. Work station 70 may be pivoted around hinge 72 until it projects rearwardly from trailer 15. One or more detachable and/or retractable legs 73 (as shown in
Work station 70 may optionally include (as shown in
In a trailer of the type shown in
Work station 70 is optionally detachable from trailer 10, as shown in
Trailer body 14 may be sealed to block ingress of water around edges of work station 70. In an example embodiment, shown in
