1. Field of the Invention
The present invention relates to a foldable tent, and more particularly to a foldable tent which utilizes a hub or roof connecting mechanism.
2. Description of Prior Art
Hubs or roof connecting mechanisms of foldable tents are often used for pivotally connecting tent poles to a central location so that the tent would be able to have a foldable function.
Roof connecting mechanisms or hubs in the conventional bell tents are only provided for purposes of connecting components of the tent such as roof strut rods or poles. In other words, those parts require assembly and disassembly when the tent is pitched and stored away, respectively.
In larger conventional tents, the roof connecting mechanism or hub is kept in hinge connection with the roof strut rods or poles such that when the tent is folded, all of the roof strut rods or poles centrally pivot around the hub and are bent down so that the poles are gathered closely together. However, the larger conventional tents also require that the poles be further supported by sub-braces which connect from the poles to a downward extended portion of the hub. As a result, not only do the connecting mechanisms of the sub-braces become intricate but the overall structure of the tent framework becomes complicated. Moreover, the volume of the tent is larger due to the number of the components of the hub assembly, and opening and closing the tent becomes more difficult.
It is therefore a main object of the present invention generally is to provide a foldable canopy tent with a relatively smaller volume having a simplified roof connecting mechanism or hub for carrying out opening and closing functions without assembly or disassembly, which can also be manufactured at a low cost. For achieving the above-mentioned object, the present invention provides a roof connecting mechanism or hub of a foldable tent for pivotally connecting a plurality of radially spaced apart poles. The connecting hub comprises a base for preventing the poles from pivoting beyond the surface of the base.
In one aspect, the present invention provides a foldable tent convertible between an open configuration and a closed configuration, said tent comprising: a hub; a plurality of separate base members, each extending radially from the hub; a plurality of slots, each slot formed on a respective base member, the plurality of slots uniformly spaced apart radially, each slot formed by first and second walls, each of the first and second walls integrally formed on the respective base member and substantially parallel to each other, each of the first and second walls having a hole to form a pair of holes extending normally through the walls of each slot, the pair of holes being substantially aligned; a plurality of poles corresponding to the number of slots, each pole having at least two sections coupled by a joint, each pole having an inner end and an outer end, a hole extending through each pole proximate the inner end; a plurality of protective members, each protective member having a length and coupled to a respective pole inner end, a hole extending through each protective member substantially perpendicular to the length; a plurality of end members, each end member corresponding to and fixed to the outer end of each pole; and a plurality of pivot members corresponding to the number of slots, each pivot member of each slot defining a pivoting axis and extending through the hole of the first wall, the corresponding holes of each pole and protective member and the hole of the second wall, such that each pole is pivotally connected to a corresponding slot.
In another aspect, the present invention provides a foldable tent convertible between an open configuration and a closed configuration, said tent comprising: a hub; a base, portions of which form a plurality of separate base members, each base member extending radially from the hub; a plurality of slots, each slot formed on a respective base member, the plurality of slots uniformly spaced apart radially, each slot formed by first and second walls, each of the first and second walls integrally formed on the respective base member and substantially parallel to each other; a plurality of poles corresponding to the number of slots, each pole having at least two sections coupled by a joint, each pole having an inner end and an outer end; a plurality of protective members, each protective member having a length and coupled to a respective pole inner end; a plurality of end members, each end member corresponding to and fixed to the outer end of each pole; and a plurality of pivot members corresponding to the number of slots, each pivot member of each slot defining a pivoting axis and extending through the first and second walls, corresponding pole and corresponding protective member such that each pole is pivotally connected to a corresponding slot over a corresponding base member.
In another aspect, the present invention provides a foldable tent convertible between an open configuration and a closed configuration, said tent comprising: a hub; a substantially circular base having a plurality of separate base members, each extending radially from the hub; a plurality of slots, each slot formed on a respective base member, the plurality of slots uniformly spaced apart radially, each slot formed by first and second walls, each of the first and second walls integrally formed on the respective base member and substantially parallel to each other; a plurality of poles corresponding to the number of slots, each pole having at least two sections coupled by a joint, each pole having an inner end and an outer end, each pole inner end pivotally coupled to a corresponding slot, the hub and poles defining a periphery when the tent is in the open configuration; and a canopy positioned within the periphery, the canopy being slidably connected to the poles in the open and closed configurations.
The foregoing summary, as well as the following detailed description of presently preferred embodiments of the invention, will be better understood when read in conjunction with the appended drawings. For the purpose of illustrating the invention, there are shown in the drawings embodiments which are presently preferred. It should be understood, however, that the invention is not limited to the precise arrangements and instrumentalities shown.
In the drawings:
Referring to
The hub assembly further comprises a plurality of roof strut rods or poles 2, each having at least two sections coupled by a joint 21, and each pole 2 is received by a corresponding slot 11. Each of the poles 2 are telescoping via a telescope locking member 25 and allows for the poles 2 to compact further in the closed configuration as described in more detail below. A pivoting cap or protective member 3 having a curved lug or curved outer surface 31 is fixed on the inner end of each pole 2 such that each cap 3 is sufficiently secured or tightly fit onto each pole 2. It is preferred that the external diameter of the pivoting cap 3 is less than or equal to the width of the inside of the slot 11, which allows for the each pole 2 to pivotally maneuver in and out of each corresponding slot 11. Each corresponding pole and cap have holes extending through the pole and cap such that the holes are substantially aligned.
The poles 2 extend radially outward from the hub 1 and each pole 2 is pivotally connected to a corresponding slot 11 proximate the radially inner end of each slot 11. A pivoting pin or pivot member 4 extends through each cap 3 and corresponding pole 2 at a radially inner end of each cap 3 and each end of the pivoting pin 4 extends into the pivoting holes 41 on each side of the walls 51 of each slot 11 thereby forming a pivoting axis for the poles 2. The pivoting pin 4 can be any type of fastener such as a rod, bolt or screw as shown, for example, in
In the first embodiment of the present invention, shown in
In operation, the tent of the first embodiment is opened by pulling the frame of the tent, i.e., the poles 2, radially outward (see
Similarly, to close the tent the feet 53 of the poles 2 are first disengaged from the supporting surface. Without support from the feet of the poles 2, the hub 1 moves downward due to its weight and assists in the closing of the tent. The bottom portions of the poles 2 are telescopically retracted and folded radially inward toward the hub 1 (see
Referring to
The hub assembly further comprises a plurality of roof strut rods or poles 2 and, similar to the arrangement in the first embodiment, each pole 2 is received by a corresponding slot 11. A pivoting cap or protective member 3 is fixed on the inner end of each pole 2 such that each cap 3 is sufficiently secured or tightly fit onto each pole 2. It is preferred that the external diameter of the pivoting cap 3 is less than or equal to the width of the inside of the slot 11, which allows for the cap 3 of each pole 2 to pivotally maneuver in and out of each corresponding slot 11. Each corresponding pole and cap have holes extending through the pole and cap such that the holes are substantially aligned.
The poles 2 extend radially outward from the hub 1 and each pole 2 is pivotally connected to a corresponding slot 11 proximate the radially outer end of each slot 11. A pivoting pin or pivot member 4 extends through each cap 3 and corresponding pole 2 at a radially outer end of each cap 3 and each end of the pivoting pin 4 extends into the pivoting holes 41 on each side of the walls 51 of each slot 11, thereby forming a pivoting axis for the poles 2. Alternatively, the poles 2 can be directly connected to the connecting hub 1 without a pivoting cap as shown in
Referring again to
In operation, similar to the operation of the tent in the first embodiment, the tent of the second embodiment is opened by pulling the frame of the tent, i.e., the poles 2, radially outward (see
Referring to
As described above, the slots 11 of the hub 1 not only restrict the poles 2 from pivoting beyond the base 12 in the open configuration but also provide for the poles 2 to pivot into a folded, compact closed configuration. Furthermore, the structure is simplified and the material cost is reduced while providing an easy and convenient opening and closing operation.
The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
