COLLAPSIBLE SHELVING DEVICE
A shelving device comprising: shelves having an outer shell enclosing a grid of shelving units so as to be erectable from a collapsed configuration of the shelving device, in which the shelves are in an accumulated condition, to an erected configuration of the shelving device, in which the shelves are stretched out to define the shelving units. A structure mechanism stretches the shelves to the erected configuration. The structure mechanism has a pole hub. Poles each have a top end pivotally connected to the pole hub and a body longitudinally connected to the outer shell of the shelves. A stretch mechanism is operatively interconnected to the poles and is manually displaceable to pivot the body of the poles away from one another about the pole hub so as to have the poles stretch the shelves to the erected configuration.
This patent application claims priority on U.S. Provisional Patent Application No. 60/786,404, filed on Mar. 28, 2006, by the present applicant.
BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention generally relates to camping equipment and, more particularly, to a portable shelving device.
2. Background Art
Whether it be in sports, leisure, or work-related activities, temporary housing is commonplace. Tents, rudimentary shelters and the like are associated with wilderness, in sport/leisure activities such as camping, and work-related activities, such as cutting, tree planting. Although tents and shelters are used on a temporary basis, campers may stay on a same site for several days.
These activities have evolved to enhance the comfort of campers, especially when camping trips are over a few nights. Therefore, domestic tools that used to be confined to the comfort of the home, have now reached the wilderness, and have become an essential part of camping. In addition to classic camping items such as flashlights and insect repellent, campers often carry around reading lights, books and other reading material, tissue and toilet paper, alarms, cameras, portable music players and a plurality of such accessories.
However, tents and shelters remain rudimentary, and often simply consist of a floor surrounded by walls. Therefore, the above-enumerated camping accessories are typically all over the floor, if not all mixed up in a bag. This is a nuisance to campers in many instances. For example, campers may lose some time and sleep trying to find accessories such as the flashlight, without which the camper may have problems exiting the tent at dusk.
SUMMARY OF INVENTIONIt is an aim of the present invention to provide a collapsible shelving device that addresses issues associated with the prior art.
Therefore, in accordance with the present invention, there is provided a shelving device comprising: shelves having an outer shell enclosing non-rigid vertical panels interconnected with non-rigid horizontal panels to form a grid of shelving units so as to be erectable from a collapsed configuration of the shelving device, in which the shelves are in an accumulated condition, to an erected configuration of the shelving device, in which the shelves are stretched out to define the shelving units; and a structure mechanism to stretch the shelves to the erected configuration, the structure mechanism having: a pole hub, poles each having a top end pivotally connected to the pole hub and a body longitudinally connected to the outer shell of the shelves, and a stretch mechanism operatively interconnected to the poles and manually displaceable to pivot the body of the poles away from one another about the pole hub so as to have the poles stretch the shelves to the erected configuration.
Further in accordance with the present invention, there is provided a method for erecting a shelving device, comprising the steps of: providing non-rigid shelves secured to poles of a structure mechanism, with ends of the poles being pivotally connected to a pole hub, and with a cable of a stretch mechanism associated with the pole hub and poles; positioning a first hand on the hub; grasping a free end of the cable with a second hand; pulling the free end of the cable away from the hub whereby the poles stretch the shelves to an erected configuration.
Having thus generally described the nature of the invention, reference will now be made to the accompanying drawings, showing by way of illustration a preferred embodiment thereof and in which:
Referring now to the drawings, and more particularly to
The shelves 12 are made of a canvas, cloth, fabric, or the like, and are non-rigid. The shelves 12 are made of various panels interrelated (i.e., sewn) to define the configuration illustrated in
The structure mechanism 14 is associated with the shelves 12 so as to define the structure of the shelving device 10. The structure mechanism 14 is manually or automatically actuatable toward a retracted state, in which the shelving device 10 is collapsed.
Referring to
The shelves 12 are provided with horizontal shelf panels 23 and vertical shelf panels 24, so as to form a grid of compartments (i.e., shelving units) as shown in
Referring to
In order to cooperate with the structure mechanism 14, the shelves 12 are provided with sleeves 30. In the embodiment illustrated in
Loops 31 are provided adjacent to a central top of the shelves 12. The loops 31 are each aligned with a respective sleeve 30 and the central top of the shelves 12. A central opening 32 is defined in the outer shell 20 at the central top of the shelves 12. Lateral openings 33 are provided in the outer shell 20, in alignment with the open ends of the sleeves 30 and the respective loops 31.
Referring to
The structure mechanism 14 also has a stretch mechanism that has stretcher hub 50 positioned below the pole hub 40, and in axial alignment therewith. Stretcher rods 51 are pivotally connected to the stretcher hub 50 by way of hub hinges 52. The stretcher rods 51 are each pivotally connected to a respective one of the poles 41 by stretcher hinges 53. A pullable deployment cable 54 extends upwardly from the stretcher hub 50, and passes through the central bore 43 in the pole hub 40. A quick-release blocking device 55 is displaceable on the deployment cable 54. The quick-release blocking device 55 is of the type that is displaceable by pushing its detent and moving it along the cable 54 to select a position of the blocking device 55. A pullable retraction cable 56 has a free end secured to the stretcher hub 50.
Now that the various components of the shelves 12 and the structure mechanism 14 have been described, the correlation between the shelves 12 and the structure mechanism 14 will be described.
As seen in
The pole hub 40 and the stretcher hub 50 (not visible in
When the collapsible shelving device 10 is in its collapsed configuration, as in
In order to deploy the collapsible shelving device 10 to its erected configuration illustrated in
Accordingly, as the poles 41 are retained in the sleeves 30 (
Referring to
Although the embodiment illustrated in
The pullable deployment cable 54 may be substituted with a rod or the like. The cable 54 or like substitute guides the stretcher hub 50 toward the pole hub 40. A cable is advantageously used as excess cable coming out of the pole hub 40 simply falls onto the shell 20. A rigid actuator (e.g., rod), would typically project upwardly from the pole hub 40 and therefore does not represent an efficient space-saving solution. However, the cable 54 can be replaced by a rod in view of using a mechanism for the automatic deployment of the shelving device 10.
