Abstract:
1. A foldable tent, comprising: a covering; a plurality of outer poles; and a plurality of frames connected to the outer poles, wherein the frames include a plurality of outer peripheral frames that define an outer peripheral shape of the frames, and a plurality of reinforcement frames disposed inside of and surrounded by the outer peripheral frames, and the outer peripheral frames are disposed on an upper portion of the poles to link neighboring outer poles and to form a polygon, wherein each of the outer poles are positioned at the vertexes of the polygon in a plan view, and each of the outer poles is connected to a respective one of the reinforcement frames, the reinforcing frames extending from the outer poles in a direction towards a center of the polygon, and the foldable tent further comprising: a center pole provided at the center of the polygon and supported by the reinforcement frames, wherein each of the outer peripheral frames and each of the reinforcement frames includes two or more pairs of combined pipe units, at least one intersecting point being formed at each of the pipe units, one of the pipe units and the other pipe unit being joined at the intersecting points to allow rotation, the outer peripheral frames and the reinforcement frames being foldable by changing an angle between adjacent one of the pipe units, and wherein the covering is supported by the poles, the outer peripheral frames and the reinforcement frames, wherein the two or more pairs of combined pipe units of the reinforcement frames serve as reinforcement pipe units, and each includes two or more pairs of reinforcement unit pipe bodies that are foldably connected end-to-end one to another, each of the two or more pairs of reinforcement unit pipe bodies including a first unit pipe body and a second unit pipe body, each of which has one of the intersecting points formed at an intermediate point along its length, and a folding point formed at each end thereof, the first unit pipe body and the second unit pipe body of each pair of reinforcement unit pipe bodies being rotatably connected to each other at their respective intersecting points, the first unit pipe bodies of the two or more pairs of reinforcement unit bodies being arranged end-to-end and being foldably connected at their folding points, and the second unit pipe bodies of the two or more pairs of reinforcement unit bodies being arranged end-to-end and being foldably connected at their folding points, thereby allowing rotation between adjacent ones of the reinforcement unit pipe bodies, and enabling the reinforcement frames to be foldable, wherein the folding points of the first and second unit pipe bodies closest to the center pole serve as pairs of connection points to the center pole, and the folding points of the first and second unit pipe bodies closest to the outer poles serve as pairs of connection points to the outer poles, and when the tent sets on a horizontal surface, the pairs of connection points of the first and second unit pipe bodies closest to the center pole are at higher positions than positions of the pairs of connection points of the first and second unit pipe bodies closest to the outer poles, wherein one of the two connection points at each of the outer poles is adapted to be slidable upwardly and downwardly by a first predetermined distance, and one of the two connection points at the center pole is adapted to be slidable upwardly and downwardly by a second predetermined distance smaller than the first predetermined distance, wherein the other of the two connection points at each of the outer poles and the center pole not adapted to slide upwardly and downwardly, and wherein all of the connection points at the outer poles and the center poles are adapted to be rotatable around axes of the poles.
