Title: Finishing panel fixing device

Description:
TECHNICAL FIELD 
     The present invention relates to a finishing panel fixing device, and more specifically, to a finishing panel fixing device which allows a finishing panel to be stably and simply installed when the finishing panel for finishing an indoor or outdoor wall or an indoor or outdoor floor is installed. 
     BACKGROUND ART 
     Generally, finishing work is performed on surfaces of wall structures to beautifully decorate exterior walls of buildings that are exposed to the outside. In the wall finishing work, various finishing methods are known and performed conventionally, and recently, a construction method that attaches finishing panels to walls of a building consecutively has been widely used as a method of finishing a building wall, wherein the finishing panel is formed of a material, such as natural stone, artificial stone, a metal plate, a synthetic resin plate, and a wooden board, in a rectangular shape and a predetermined size. 
     As an example of related technology for assembling and disassembling a finishing panel and mounting a finishing panel to a wall of a structure, “Construction Structure of Decorative Panel of Building and Construction Method Thereof” is disclosed in Korean Laid-open Patent Application No. 10-2005-0104117. 
     The construction structure of a decorative panel of a building and the construction method thereof are formed to include a panel fixing device which is installed on a wall of a building and adjusts a gap between the wall and a decorative panel, a fastening groove that is formed in a front surface of the panel fixing device, on which a decorative panel is installed, and that has an open upper portion, and a fastening unit installed on a rear surface of the decorative panel and fastened in the fastening groove to prevent the decorative panel from moving. 
     In the conventional construction structure of a decorative panel of a structure and the construction method thereof, a wall surface of the constructed decorative panel is even without unevenness. However, a great deal of time for assembling and disassembling is required due to a complicated assembling process in which as many fixing angles should be installed on a wall of a building as decorative panels to be constructed, fixing brackets should be assembled to the fixing angles using bolts and nuts one by one, and the decorative panel is assembled to the fixing brackets using bolts and nuts, and thus there is a problem of low effectiveness. 
     To solve the problem, “Wall Structure” is disclosed in Korean Laid-open Patent Application No. 10-2009-0053661, wherein the wall structure includes a fixing frame which is fixed to a concrete wall and includes a plurality of lateral bars and a plurality of vertical bars that are integrally formed, a finishing panel which is disposed on the lateral bars and the vertical bars to finish the concrete wall and includes a flat plate and an elastic piece bent from the plate toward a rear side of the plate, a fastened unit provided on any one of the fixing frame and the finishing panel, and a fastening unit provided on the other one thereof and fastened in the fastened unit to be coupled thereto. 
     The wall structure has an advantage of being simply assembled and disassembled, but the fastened units for the finishing panel should each be installed on the fixing frames, and particularly, the finishing panel is not fixed while being mounted on the fixing frame by the fastened unit, and thus there is a problem in that the finishing panel is easily separated or disassembled from the fastened unit of the fixing frame due to an external factor.

     DETAILED DESCRIPTION 
     Hereinafter, a finishing panel fixing device according to one embodiment of the present invention will be described in detail with reference to the accompanying drawings. 
     In  FIGS. 1 to 5 and 11 , a finishing panel fixing device  1  according to one embodiment of the present invention is shown. Referring to  FIGS. 1 to 5 and 11 , the fixing device according to one embodiment of the present invention includes a base  100  and a gripping clip  200 . 
     As shown in  FIGS. 1 to 5 and 11 , the base  100  is detachably coupled to a support frame  7 , which is fixedly installed on a wall  5  or a floor  6  so that finishing panels  3  are installed on the wall  5  or the floor  6 , and includes a mounting plate  110  and a reinforcing plate  120 . 
     The base  100  may be inserted inward of the support frame  7  from both sides of a longitudinal direction of the support frame  7  and installed or, unlike this, may enter toward an opening formed in one side of the support frame  7  and be rotated at a predetermined angle for installation. 
     The mounting plate  110  has a predetermined thickness, is formed in a flat rectangular shape having flat upper and lower surfaces, and has a gently rounded edge. 
     Further, the mounting plate  110  includes a plurality of mounting holes  111  that pass through upper and lower surfaces of the mounting plate  110  so that the gripping clip  200  described below is inserted from a lower side of the mounting plate  110  toward an upper side thereof and mounted. The mounting holes  111  are formed in a rectangular shape, and as shown in the drawings, inner circumferential surfaces of the mounting holes  111  are formed in a vertical direction to be perpendicular to the upper and lower surfaces of the mounting plate  110 . 
     Unlike this, as shown in  FIG. 6 , a width of the inner circumferential surface of the mounting hole  111  is gradually decreased in an upward direction so that the inner circumferential surface comes into contact with outer peripheral surfaces of pressing ribs  220  of the gripping clip  200  described below, but the inner circumferential surface of the mounting hole  111  may have an inclination corresponding to an inclination of the pressing rib  220 . 
     Further, the mounting plate  110  includes a plurality of coupling holes  112  formed around the mounting holes  111  to be coupled with the reinforcing plate  120  to be described below and a plurality of first fixing holes  113  formed to be spaced apart from each other to allow the mounting plate  110  to be fixed to the support frame  7  using a fixing bolt or a fixing piece. 
     Further, the mounting plate  110  further includes withdrawal preventing protrusions  114  that prevent the gripping clip  200  from being extracted upward from the mounting plate  110 . The withdrawal preventing protrusions  114  extend upward from an upper surface of the mounting plate  110  around the mounting holes  111  to be inclined and restrict the pressing ribs  220  of the gripping clip  200 . 
     Further, the mounting plate  110  further includes a withdrawal prevention groove  115  that prevents the gripping clip  200  from being extracted upward from the mounting plate  110 . The withdrawal prevention groove  115  is recessed upward from a lower surface of the mounting plate  110  around the mounting holes  111  by a predetermined depth so that a part of the gripping clip  200 , specifically a locking protrusion of the gripping clip  200 , enters the withdrawal prevention groove  115 . The locking protrusion of the gripping clip  200  that enters the withdrawal prevention groove  115  is prevented from moving upward from the mounting plate  110  by the mounting plate  110 . 
     The reinforcing plate  120  is coupled to a lower side of the mounting plate  110  to prevent the gripping clip  200  mounted in the mounting holes  111  of the mounting plate  110  from being extracted downward from the mounting plate  110  so as to support the gripping clip  200 , has a predetermined thickness to correspond to an exterior of the mounting plate  110 , and has a flat rectangular shape having flat upper and lower surfaces and a gently rounded edge. 
     Further, the reinforcing plate  120  includes coupling protrusions  122  formed at portions corresponding to the coupling holes  112  of the mounting plate  110  and second fixing holes  123  formed at positions corresponding to the first fixing holes  113  so that a fixing bolt, a fixing piece, or the like passes therethrough. 
     One side of the gripping clip  200  is coupled to the base  100 , and the other side thereof is formed to grip the finishing panels  3 . In the embodiment, the gripping clip  200  includes a mounting plate  210  and the pressing ribs  220 . 
     The mounting plate  210  has a size and a shape corresponding to the mounting hole  111 , has a rectangular shape of which one side is a long side longer than a short side, and has a thickness smaller than or corresponding to the mounting plate  110 . 
     Further, the pressing ribs  220  extend from both end portions in a width direction of the mounting plate  210  by a predetermined length to increase a distance from the mounting plate  210 , are formed to be inclined in a direction in which end portions of the pressing ribs  220  are close to each other, and have bent parts formed at end portions thereof and bent in a direction away from each other so that skirt parts  3   a  of the finishing panels  3  easily enter between the pressing ribs  220 . 
     Further, the base  100  of the finishing panel fixing device  1  according to the present invention further incudes a coupling part for coupling the reinforcing plate  120  with the mounting plate  110 . 
     The coupling part includes a plurality of coupling protrusions  122  that protrude upward from an upper surface of the reinforcing plate  120  and coupling holes  112  that vertically pass through the mounting plate  110  so that the coupling protrusions  122  pass therethrough. Since a length of the coupling protrusion  122  is greater than a thickness of the mounting plate  110 , the coupling protrusions  122  pass through the coupling holes  112  and are bent toward one side thereof so that the mounting plate  110  is tightly coupled to the reinforcing plate  120 . 
     As one example of the coupling part, a structure of the coupling protrusions  122  and the coupling holes  112  is applied, but unlike this, a rivet member, a fixing bolt, a fixing piece, or the like may be used for coupling. 
     Meanwhile, as shown in  FIG. 6 , when the finishing panel fixing device  1  according to the present invention excludes the withdrawal preventing protrusions  114  and inner circumferential surfaces of the mounting holes  111  have inclinations that correspond to inclinations of the pressing ribs  220 , the gripping clip  200  can be prevented from being extracted upward from the mounting plate  110  by the mounting holes  111 . 
     Further, as shown in  FIGS. 7 to 10 , the base  100  of the finishing panel fixing device  1  according to the present invention may further include an elastic part  130  that elastically supports the gripping clip  200  upward from a lower side of the gripping clip  200  and an elevated part  140  that supports the mounting plate  110  to be spaced apart from the reinforcing plate  120  by a predetermined distance. 
     As shown in  FIGS. 7 and 8 , as an example of the elastic part  130 , an elastic piece  131  may be applied, wherein the elastic piece  131  is formed by cutting a part of the reinforcing plate  120  disposed below the gripping clip  200  and bending the cut portion upward at a predetermined angle. The elastic piece  131  is bent or curved upward and allows one end portion to vertically vibrate from the other side connected with the reinforcing plate  120 . 
     Further, the elevated part  140  is formed by uplifting a part of the reinforcing plate  120  upward from a lower side of the reinforcing plate  120 , and an upper surface of the elevated part  140  is formed flat to be pressed against a lower surface of the mounting plate  110 . The above-described coupling protrusions  122  may be formed on an upper surface of the elevated part  140 . 
     As shown in  FIG. 8 , when the skirt parts  3   a  of the finishing panels  3  enter between the pressing ribs  220  of the gripping clip  200 , the above-described structure may prevent the pressing ribs  220  from being bent when a force is concentrated on a part of the pressing ribs  220  at which outer circumferential surfaces of the pressing ribs  220  come into contact with the withdrawal preventing protrusions  114 . 
     That is, the elevated part  140  includes a space part formed between the mounting plate  110  and the reinforcing plate  120  so that the pressing ribs  220  retract to the reinforcing plate  120 , and when the pressing ribs  220  are not in contact with the withdrawal preventing protrusions  114 , the retracted gripping clip  200  is not restricted by the withdrawal preventing protrusions  114  and is naturally open. 
     Further, when the gripping clip  200  retracts, the elastic part  130  is bent downward, and when the skirt parts  3   a  of the finishing panels  3  completely enter between the pressing ribs  220 , the elastic part  130  presses the gripping clip  200  toward the mounting plate  110  due to elasticity, and thus the gripping clip  200  returns to an original position, that is, into the mounting holes  111 , and allows the gripping clip  200  to be continuously positioned in the mounting holes  111  so as to prevent the pressing ribs  220  of the gripping clip  200  from being open. 
     As shown in  FIGS. 9 and 10 , the elastic part  130  may include an elastic part  132  that has a pad form of which the exterior is deformed when an external force is applied and returns to an original state when the external force is removed. The elastic part  132  may be formed of a highly elastic material, wherein, when the skirt parts  3   a  of the finishing panels  3  enter between the pressing ribs  220  of the gripping clip  200 , the highly elastic material contracts due to the gripping clip  200  that retracts, and when the skirt parts  3   a  of the finishing panels  3  completely enter between the pressing ribs  220 , the highly elastic material is expanded due to elasticity, that is, returns to an original state so as to press the gripping clip  200  toward the mounting plate  110 . 
     Meanwhile, a finishing panel fixing device  2  according to another embodiment of the present invention is shown in  FIGS. 12 and 13 . Referring to  FIGS. 12 and 13 , the finishing panel fixing device  2  according to the embodiment includes a base  100 , gripping clips  300 , and a fixing part. 
     The gripping clips  300  are formed by partially cutting and bending a flat plate with a predetermined area, and the plurality of gripping clips  300  are disposed adjacent to each other in four directions on the base  100 . 
     The gripping clip  300  includes a first vertical part  311  and a second vertical part  312  disposed on the base  100  to be perpendicular to the base  100  and bent to be perpendicular to each other, a first pressing rib  321  and a second pressing rib  322  that extend from upper end portions of the first vertical part  311  and the second vertical part  312  to increase distances from the first vertical part  311  and the second vertical part  312  and press side surfaces of skirt parts  3   a  of finishing panels  3 , and a first lateral part  331  and a second lateral part  332  that extend from lower end portions of the first vertical part  311  and the second vertical part  312  to increase distances from the first vertical part  311  and the second vertical part  312  and are supported to be pressed against the base  100 . 
     The first pressing rib  321  of one gripping clip  300  is disposed to face the second pressing rib  322  of the other gripping clip  300  which is adjacent thereto, and the second pressing rib  322  of the one gripping clip  300  is disposed to face the first pressing rib  321  of another gripping clip  300  which is adjacent thereto, and thus both surfaces of the skirt parts  3   a  of the finishing panels  3  are pressed and gripped. That is, the gripping clip  300  cannot grip the skirt parts  3   a  of the finishing panels  3  alone but can grip the skirt parts  3   a  of the finishing panels  3  along with the gripping clip  300  adjacent thereto. 
     The first pressing rib  321  and the second pressing rib  322  are bent from the first vertical part  311  and the second vertical part  312  several times, respectively, but unlike this, may be bent in a curved form. 
     The fixing part, which is for fixing the gripping clip  300  to the base  100 , includes a fastening member  410  passing through the first lateral part  331  or the second lateral part  332  and fastened with the base  100 . A rivet, a fixing bolt, a fixing piece, or the like may be used as the fastening member  410 , and in the embodiment, a rivet member having flat upper and lower portions is used. 
     Meanwhile, as shown in the drawings, the finishing panel fixing device according to the present invention has a structure in which four gripping clips are disposed in four directions perpendicular to each other and fix four finishing panels that are adjacent to each other, but the present invention is not limited thereto. For example, in the finishing panel fixing device according to the present invention, one gripping clip is installed on one base, two gripping clips are installed on one base in a direction in which the two gripping clips are perpendicular to each other or are in parallel, or three gripping clips are installed on one base in a direction in which the three gripping clips are perpendicular to each other. 
     Further, the base of the finishing panel fixing device according to the present invention may also has a structure in which the base is partially cut from a rectangular shape shown in the drawings due to installation space constraints. That is, while the four gripping clips are mounted on one base, the base is cut in a predetermined direction, and thus the base may be used to be separated into a portion in which three gripping clips are mounted on one base and a portion in which one gripping clip is mounted on one base. 
     While the finishing panel fixing device according to the present invention has been described above with reference to the accompanying drawings, these are only examples. It may be understood by those skilled in the art that various modifications and equivalent other embodiments may be made. Therefore, the true scope of the technical protection of the present invention should be defined only by the technical spirits of the appended claims.
