Description

A CLOTH LENGTH CONTROLLER FOR HEIGHT ADJUSTING

TENT

Technical Field

[1] The present invention relates to a cloth length controller for a height adjusting tent, and more particularly, to a cloth length controller for a height adjusting tent, the cloth length controller capable of preventing the formation of creases in a tent cloth of the height adjusting tent which can always be set upright on an inclined surface. Background Art

[2] Conventional tents are used mainly for outdoor camping and classified into manual tents and automatic tents. To set up manual tents, poles are manually coupled to one another. On the other hand, automatic tents work in a manner similar to umbrellas. Thus, automatic tents can be easily set up and taken down.

[3] Since the lengths of both manual and automatic tents are fixed, the manual and automatic tents must always be set up on a level ground. That is, since the lengths of manual and automatic tents are fixed, if the manual and automatic tents are set up on, for example, a slope or beach which is at an angle, they often fail to stand straight up and easily fall down.

[4] A conventional art for solving this problem is disclosed in Korean Patent Application No. 2005-33972 (entitled Tent-Height Controller And Tent Employing the Same ) which was filed by the present applicant on April 25, 2004 and patented on September 19, 2006.

[5] The conventional art relates to a tent-height controller, which can easily control the lengths of length- variable lower support poles of a manual or automatic tent (hereinafter, referred to as a tent ) and thus enable the tent to always stand straight up even when the tent is set up on an inclined surface, and a tent employing the tent- height controller. The conventional art will now be described in more detail with reference to the attached drawings.

[6] FIG. 1 is a front view of a conventional tent employing a tent-height controller.

FIG. 2 is a front view of another conventional tent employing another tent-height controller. FIG. 3 is an exploded perspective view of one of length- variable lower support poles 50 of the tent-height controller shown in FIG. 1 or 2. FIG. 4 is a cross- sectional view of the length- variable lower support pole 50 of FIG. 3.

[7] Referring to FIGS. 1 through 4, the tent-height controller of the conventional tent of

FIG. 1 or 2 includes upper connecting poles 1, the lower support poles 50, a support 13, and a tent cloth 75. The upper connecting poles 1 can be spread out in all directions, and the lower support poles 50 are coupled to the upper connecting poles 1, respectively, and set up on a ground surface. In addition, the support 13 facilitates the radial stretching of the upper connecting poles 1, and the tent cloth 75 is coupled to the upper connecting poles 1 and the lower support poles 50. The lengths of the lower support poles 50 can be adjusted, and the length of a lower portion of the tent cloth 75, which is coupled to the lower support poles 50, can also be adjusted by a cloth length controller of FIG. 1 or 2. Therefore, even when the conventional tent is set up on an inclined surface, it can always stand straight up.

[8] Each of the lower support poles 50 includes the fixing pole 54, the movable pole 52, and the stopper 56. The fixing pole 54 is set up on the ground surface. An end of the movable pole 52 is coupled to one of the upper connecting poles 1, and the other end of the movable pole 52 is coupled to the fixing pole 54 and can be inserted into or removed from the fixing pole 54. The stopper 56 is fixed to an upper end of the fixing pole 54 and restricts the movement of the movable pole 52. Specifically, the stopper 56 includes a cylindrical guide 56a and an eccentric cylindrical rotor 56b. The cylindrical guide 56a guides the movable pole 52 into or out of the fixing pole 54. The eccentric cylindrical rotor 56b is rotatably coupled to a side of the cylindrical guide 56a.

[9] The cloth length controller of FIG. 1 is attached to the lower portion of the tent cloth 75 which is coupled to the lower support poles 50. The cloth length controller includes one or more zippers 90 and 96 which expand the lower portion of the tent cloth 75 as they run from a starting point to an end point.

[10] On the other hand, the cloth length controller of FIG. 2 has a rubber band-based folding structure 100. The rubber band-based folding structure 100 is integrated into the lower portion of the tent cloth 75 which is coupled to the lower support poles 50.

[11] As described above, when the conventional tent is set up on an inclined surface, the tent-height controller of the conventional tent reduces the lengths of some of the lower support poles 50 which are placed at a higher position on the inclined surface. Therefore, even when the conventional tent is set up on the inclined surface, it can always stand upright in a stable manner.

[12] However, the process of manufacturing the zipper- type cloth length controller shown in FIG. 1 is complicated since a slider and a plurality of teeth must be formed in the tent cloth 75. In addition, when the zipper-type cloth length controller is used, foreign matter or tent canvas may be caught between teeth thereof, thereby making it difficult for the slider to smoothly run along the teeth. In the case of the tent-canvas controller having the rubber band-based folding structure 100 shown in FIG. 2, a rubber band must be inserted into the tent canvas 75 to form creases. Therefore, the process of manufacturing the tent-canvas controller is complicated and takes a long time, thereby deteriorating manufacturing efficiency. Disclosure of Invention

Best Mode for Carrying Out the Invention

[41] The present invention will now be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. The invention may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth therein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the invention to those skilled in the art.

[42] A cloth length controller according to the present invention can be applied to various forms of conventional height adjusting tents. Thus, exemplary embodiments of the present invention will be described below by using one of the conventional height adjusting tents as an example.

[43] FIG. 5 is a front view of a cloth length controller for a height adjusting tent according to a first exemplary embodiment of the present invention. FIG. 6 shows the installation state of the cloth length controller for the height adjusting tent according to the first exemplary embodiment of the present invention.

[44] Referring to FIGS. 5 and 6, the cloth length controller according to the first exemplary embodiment of the present invention is installed in a conventional height adjusting tent.

[45] The conventional height adjusting tent includes a connecting member 10, a sliding member 20, an elastic spring 30, a plurality of lower support poles 50, and a tent canvas 75. A plurality of upper connecting poles 1 are connected to an upper end of the connecting member 10 in all directions, and a stopper 3 is fixed to a lower end of the connecting member 10. In addition, a connector (not shown) is integrally installed at a lower end of the stopper 3. The sliding member 20 is coupled to the connecting member 10 and can ascend or descend along the connecting member 10. A support 13 is hinge-connected to the upper connecting poles 1 and is coupled to an outer circumference of the sliding member 20.

[46] The elastic spring 30 is inserted into the connecting member 10 and maintains a predetermined gap between the sliding member 20 and the connecting member 10 when the conventional height adjusting tent is set up. The lower support poles 50 contact the upper connecting poles 1 and are foldably coupled to the upper connecting poles 1, respectively. An outer circumferential portion of the tent canvas 75 is coupled to each of the upper connecting poles 1 and the lower support poles 50, and the center of a top portion of the tent canvas 75 is coupled to the connector (not shown) of the connecting member 10 by a connecting string 77.

[47] The lengths of the lower support poles 50 can be adjusted, and the length of the tent canvas 75, which is connected to the lower support poles 50, can also be adjusted. Therefore, even when the conventional height adjusting tent is set up on an inclined surface, it can always stand straight up.

[48] When necessary, a pent-roof fixing structure 70 may be added to the conventional height adjusting tent in order to block sunlight. Since the pent-roof fixing structure 70 is a widely known technology, a detailed description thereof will be omitted.

[49] The length- variable lower support poles 50 will now be described in more detail with reference to FIGS. 3 and 4.

[50] Referring to FIGS. 3 and 4, each of the length-variable lower support poles 50 includes a fixing pole 54, a movable pole 52, and a stopper 56. The fixing pole 54 is set up on the ground surface. An end of the movable pole 52 is hinge-connected to one of the upper connecting poles 1, and the other end of the movable pole 52 is coupled to the fixing pole 54 and can be inserted into or removed from the fixing pole 54. The stopper 56 is fixed to an upper end of the fixing pole 54 and restricts the movement of the movable pole 52. Specifically, the stopper 56 includes a cylindrical guide 56a and an eccentric cylindrical rotor 56b. The cylindrical guide 56a is fixed to the upper end of the fixing pole 54 and guides the movable pole 52 into or out of the fixing pole 54. The eccentric cylindrical rotor 56b is rotatably coupled to a side of the cylindrical guide 56a.

[51] Referring back to FIGS. 5 and 6, the cloth length controller employed in the conventional height adjusting tent configured as described above includes a group 150 of connecting units 150a through 150d and a hook 300. The connecting units 150a through 150d extend from the tent canvas 75 and are connected to each of the lower support poles 50. The hook 300 is fixed to a fixing unit 160, which is formed at each lower corner of the tent canvas 75, by an elastic unit 200. Thus, when the lengths of the lower support poles 50 are reduced, the hook 300 is fixed to at least one of the connecting units 150a through 150d.

[52] The elastic unit 200 may be formed in any one or all of the connecting units 150a through 150d. Alternatively, the elastic unit 200 may be formed in the fixing unit 160 which is formed at each lower corner of the tent canvas 75. The elastic unit 200 may be made of a coil spring or any elastic material that can easily contract and expand. Preferably, a rubber band, which is light and can be manufactured at low cost, may be used as the elastic unit 200.

[53] At least one of the connecting units 150a through 150d may extend from the tent canvas 75. The connecting units 150a through 150d may be made of the same fabric or cloth as the tent canvas 75. In addition, the connecting units 150a through 150d may be sewn to the tent canvas 75 and arranged at regular intervals.

[54] An end of the elastic unit 200 is fixed to the hook 300, and the other end of the elastic unit 200 is fixed to the fixing unit 160 which is formed at each lower corner of the tent canvas 75. The fixing unit 160 is connected to a fixing holder 60 so that the tent canvas 75 can be connected to each of the lower support poles 50. In this case, a lower end of each of the lower support poles 50 is inserted into and thus fixed to the fixing holder 60.

[55] The installation state of the cloth length controller for the height adjusting tent according to the first exemplary embodiment of the present invention will now be described.

[56] Referring to FIG. 6, when the height adjusting tent is set up on an inclined surface, the lengths of some of the length- variable lower support poles 50, which are placed at a higher position on the inclined surface, are reduced so that the height adjusting tent can stand straight up. Accordingly, the hook 300, which is fixed to the fixing unit 160 at each lower corner of the tent canvas 75, is pulled upward and fastened to the connecting unit 150b which is located at a distance corresponding to a specified length by which the lengths of the lower support poles 50 at the higher position are reduced. Consequently, the length of a lower portion of the tent canvas 75 is reduced by the specified length, and the height adjusting tent is completely set up.

[57] The hook 300 connected to the elastic unit 200 pulls the connection unit 150b, which is located at a distance corresponding to the specified length by which the length of the tent canvas 75 is reduced, by using an elastic force in order to keep the tent canvas 75 stretched tight. As a result, the formation of creases or bits of fluff in the tent canvas 75 can be prevented. That is, creases or bits of fluff can be prevented from being formed in portions of the tent canvas 75 when the lengths of the lower support poles 50 are reduced to set up the height adjusting tent. Mode for the Invention

[58] Hereinafter, a cloth length controller for a height adjusting tent according to various exemplary embodiments of the present invention will be described with reference to the attached drawings.

[59] FIG. 7 is a front view of a cloth length controller for a height adjusting tent according to a second exemplary embodiment of the present invention. FIG. 8 shows the installation state of the cloth length controller for the height adjusting tent according to the second exemplary embodiment of the present invention.

[60] Referring to FIGS. 7 and 8, the cloth length controller according to the first exemplary embodiment of the present invention includes a connecting hook 400, which is formed in at least one of a plurality of connecting units 150a through 150d and coupled to a hook 300, in addition to the configuration of the cloth length controller according to the first exemplary embodiment.

[61] The connecting hook 400 may be fixed to at least one of the connecting units 150a through 150d by an elastic material or a cloth or may be directly fixed to at least one of the connecting units 150a through 150d. Since the connecting hook 400 is formed in at least one of the connecting units 150a through 150d and coupled to the hook 300, the length of a tent canvas 75 can be reduced by the same length that those of length- variable lower support poles 50 are reduced by. Consequently, the formation of creases and bits of fluff in the tent canvas 75 can be prevented.

[62] Various connecting mediums may be employed in a cloth length controller for a height adjusting tent according to the present invention, which will now be described in detail.

[63] FIG. 9 shows a connecting medium installed in a cloth length controller for a height adjusting tent according to a third exemplary embodiment of the present invention. FIG. 10 shows a connecting medium installed in a cloth length controller for a height adjusting tent according to a fourth exemplary embodiment of the present invention.

[64] Referring to FIGS. 9 and 10, a Velcro tape 310 or a dot button 320, instead of the hook 300 described above, may be installed as a connecting medium at an end of an elastic unit 200.

[65] Therefore, when the lengths of lower support poles 50 are reduced, the formation of creases and bits of fluff in the tent canvas 75 can be prevented by the Velcro tape 310 or the dot button 320. In this case, various forms of buttons, such as a toggle button, may also be used instead of the dot button 320. Reference numerals 311 and 321 indicate binding units which are coupled to the Velcro tape 310 and the dot button 320, respectively.

[66] FIG. 11 shows a cloth length controller for a height adjusting tent according to a fifth exemplary embodiment of the present invention. Referring to FIG. 11, the cloth length controller according to the fifth exemplary embodiment of the present invention includes a connecting hook 410, which is connected to at least one of a plurality of connecting units 150a through 150d by an elastic unit 200, and a connecting peg 330 which protrudes from an outer circumferential surface of an end of each of lower support poles 50.

[67] Therefore, when the lengths of the lower support poles 50 are reduced, the connecting hook 410 is coupled to the connecting peg 330, thereby keeping a tent canvas 75 stretched tight.

[68] FIG. 12 shows a cloth length controller for a height adjusting tent according to a sixth exemplary embodiment of the present invention. FIG. 13 shows the installation state of the cloth length controller for the height adjusting tent according to the sixth exemplary embodiment of the present invention.

[69] Referring to FIGS. 12 and 13, the cloth length controller according to the sixth exemplary embodiment of the present invention includes a plurality of connecting units 150a through 150d and an elastic band 340. The connecting units 150a through 150d extend from a tent canvas 75 and are coupled to each of lower support poles 50. The elastic band 340 is inserted into edges of the tent canvas 75, which are adjacent to the lower support poles 50, to be parallel to the lower support poles 50. The elastic band 340 is used to vertically contract the tent canvas 75.

[70] In this case, when the lengths of the lower support poles 50 are reduced, the elastic band 340 may contact accordingly. Thus, the length of the tent canvas 75 can be reduced, and the tent canvas 75 can be kept stretched tight without requiring an additional connecting medium. As a result, creases or bits of fluff can be prevented from being formed all over the tent canvas 75.

[71] When the lengths of the lower support poles 50 are increased, upper connecting poles 1 spread out in all directions, and a force generated here by the upper connecting poles 1 stretches the elastic band 340. Since the elastic band 340 is inserted into the tent canvas 75, the tent-canvas controller can be manufactured in a simple process. In addition, since no additional connecting medium is required, the tent-canvas controller can be easily used.

[72] While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims. Industrial Applicability

[73] As described above, a connecting medium is fixed to a lower portion of a height adjusting tent according to the present invention by an elastic unit. When the length of a tent canvas of the height adjusting tent is reduced, the connecting medium is coupled to one of a plurality of connecting units of the tent canvas. Therefore, creases or bits of fluff can be prevented from being formed in the tent canvas. In addition, since the connecting medium has a simple structure, that is, can simply be coupled to one of the connecting units of the tent canvas, it can be manufactured at low cost and in a simple process, thereby enhancing manufacturing efficiency.
