20110094553 | CONNECTOR FOR TENT POLES - Disclosed herein a connector for connecting end portions of a plurality of tent poles that intersect with one another. In one embodiment, a connector for tent poles includes a body and first, second and third pole insertion holes formed in the body. In the connector for tent poles, the first and second pole insertion holes maintain a central angle of less than 180 degrees at an intersection point at which the center lines of the first and second pole insertion holes intersect with each other, the radius direction outsides of the first and second pole insertion holes from the intersection point are opened so as to be first and second openings, respectively, and first and second wall portions are formed at the radius direction insides of the first and second pole insertion holes, respectively. The third pole insertion hole is disposed within the range of the central angle, the radius direction inside of the third pole insertion hole is opened so as to be a third opening, and a third wall portion is formed at the radius direction outside of the third pole insertion hole. | 04-28-2011 |
20120104805 | PORTABLE CHAIR - The portable chair of the disclosure includes: hubs respectively installed at both left and right sides of the chair; a central support frame connecting both left and right hubs; front and rear leg frames respectively having base ends separably coupled to the lower front and rear outer peripheral surfaces of the respective hubs and respectively having free ends disposed in a manner of radially extending toward the ground surface; front and rear pole frames respectively having base ends separably coupled to the upper front and rear outer peripheral surfaces of the respective hubs and respectively having free ends disposed in a manner of radially extending toward the sky; and a fabric sheet coupled to the free ends of the front and rear pole frames. The structural rigidity is excellent, and the chair may land on the ground surface in a stable posture. | 05-03-2012 |
20120288326 | ROTATING TYPE STICK - The present disclosure relates to a rotating type stick capable of firmly maintaining a locking state of a locking unit even when a rotational force is applied to tube members constituting a stick. Provided is a stick including: a first tube member and a second tube member connected to each other in the length direction; and a connection member connected to one end portion of the second tube member, wherein the first tube member is selectively locked to or unlocked from the connection member, the second tube member is rotatably connected to the connection member, and the second tube member is rotatable relative to the first tube member while the first tube member and the connection member are maintained in a locking state. | 11-15-2012 |
20120305041 | STICK WITH CAM LEVER TYPE LOCKING DEVICE - A stick is provided in which a gripping tube is fixed to a front end portion of an upper connection tube having a large diameter and a circular-arc engagement portion formed by a front-end cut portion of the gripping tube is tightened or loosened with the operation of a cam lever so that the outer periphery of a lower connection tube is fixed in a pressurized and gripped state or the pressurizing force is released, wherein a contracted tube portion is formed in the outer periphery of the lower connection tube at the portion with which the circular-arc engagement portion comes into contact when the lower connection tube is pressed into the upper connection tube so as to reach a shortened position, and when the cam lever is locked at the shortened position, the circular-arc engagement portion comes into contact with the contracted tube portion having a small outer diameter. | 12-06-2012 |
20130312231 | LOCKING DEVICE FOR POLE - The present invention relates to a locking device for a pole, including: a grasping tube having incision portions; operating pins adapted to be inserted in an up and down direction into upper and lower pressing parts; and an axial lever having a pressing plate extended in the lengthwise direction of the pole. | 11-28-2013 |
20130312797 | FOLDABLE POLE - The present invention relates to a foldable pole including: an upper tube having a handle mounted thereon, a lower tube having a head part mounted thereon, and one or more intermediate tubes disposed between the upper tube and the lower tube; an elastic string having one end portion fixed to the inner lower end of the lower tube or the inner upper end of the upper tube and the other end portion extended up to the inner intermediate portion of the lower tube or the upper tube; and a non-elastic string having one end portion connected to the other end portion of the elastic string and the other end portion extended fixedly up to the interior of the upper tube or the lower tube. | 11-28-2013 |
20140115780 | COT - A cot having a simple structure and capable of being easily installed and dissembled is provided. The cot includes a cloth having horizontal poles inserted into both ends thereof, a plurality of support bars for supporting a load in contact with the ground, and a plurality of connection bars connected to both ends of each support bar and respectively having clips at terminals thereof to receive the horizontal poles, wherein the clips are open toward the outside. | 05-01-2014 |
