DETAILED DESCRIPTION OF THE INVENTION

(7) Hereinafter, it should be understood that when a stopper device of a door closer of the present disclosure is specifically described, it is described in a criterion of an example according to the present disclosure, wherein technologies of the present disclosure are not intended to be limited to an embodied form described in the example described in this specification and includes various modifications, equivalents, and/or alternatives of the example of the present disclosure.

(8) In addition, when describing the example of the present disclosure, it is natural that even though an action and effect according to configurations of the present disclosure are not definitely described and explained, predictable effects based on the relevant configurations are to be also recognized.

(9) A stopper device 200 of the present disclosure is installed together with a door closer 100 and is configured to include a guide rail 210, transfer apparatus 220 sliding according to closing and opening of a door, and fixing apparatus 230 fixing the sliding transfer apparatus 220.

(10) The guide rail 210 is installed at an upper side of a door frame 300, and is formed in a longitudinal direction, wherein a sliding portion 211 is formed inside in order that the transfer apparatus 220 and the fixing apparatus 230 may be positioned and slide.

(11) Also, a side cap 213 is formed at ends of both sides in order that the transfer apparatus 220 and fixing apparatus 230 positioned at the sliding portion 211 slide and do not deviate from the guide rail 210.

(12) The transfer apparatus 220 slides by an arm 130 rotating according to opening and closing of a door 310, wherein an arm connection portion 223 to which the arm 130 is connected in order to rotate according to the arm 130 connected to a door closer 100 and a roller 221 to which a clip 240 seated at the fixing apparatus 230 is bound connected to fix the door 310 are formed, wherein the roller 221 is installed in a center of a clip receiving space 224.

(13) The fixing apparatus 230 is for fixing the sliding transfer apparatus 220, wherein a clip seating groove 231 adhered to one side of the sliding portion 211 is formed in order that a clip 240 is seated to be directly connected and fixed to the roller 221 of the transfer apparatus 220 and the seated clip 240 is prevented from deviating.

(14) Also, a fixing bolt 233 is fastened in order that an angle at which the door 310 maintaining a fixed and open state is opened may be controlled by controlling a position of the fixing apparatus 230 within the sliding portion 211 to control a whole moving distance of the sliding transfer apparatus 220.

(15) The clip 240 is coupled to the fixing apparatus 230, wherein a T shaped seating piece 247 is formed in order to be seated at the clip seating groove 231 of the fixing apparatus to be firmly fixed without distortion or shaking and an elastic piece 241 which is connected to the seating piece 247 and is exposed at the front of the clip seating groove 231 is formed. The fixing apparatus 230 is configured to form a cover seating portion 230-1 in order to put the clip 240 configuring the fixing apparatus into the clip seating groove 231 and prevent it from escaping and at the same time, fit a position with the roller 221 of the transfer apparatus and to couple a cover 230-2 thereto.

(16) Also, the elastic piece 241 is formed to have a S shape, be divided into the left and the right and face each other, wherein an opening 243 is formed at the front in order that the roller 221 of the sliding transfer apparatus 220 enters or exits and a trapping portion 245 is formed at the back of the opening 243 in order to hold an outer circumference of the roller 221 entering through the opening 243.

(17) When specifically referring to an action about the stopper device of the door closer according to the present disclosure configured as the above, the content is as follows.

(18) At the door 310 in which the door closer is installed, a case 110 covering a door closer 100, a plate 120 having a role of a stiffening plate to install at the door 310, and the door closer 100 which includes the arm 130 rotating according to opening and closing of the door 310 are installed, wherein after opening the door 310, if a visitor takes his/her hand off, the arm 130 rotates by a repulsive force of the door closer 100 and the open door 310 is slowly closed. Its structure is generally used, and thus specific description is omitted.

(19) The stopper device 200 of the present disclosure is installed at an upper end of the door frame 300 in order that the arm 130 of the door closer 100 installed at the door 310 is easily connected and rotates as the above.

(20) The stopper device 200 installed in this way rotates by the arm 130 connected to the door closer 100 as the door 310 opens and closes, and fixes the door 310 in order to maintain it in an open state at a certain angle when needed,

(21) More specifically, the arm 130 connected to the door closer 100 rotates according to the door 310 which is opened by pushing to open the closed door 310, and the transfer apparatus 220 connected to one side of the rotating arm 130 slides in a hinge direction of the door 310 within the sliding portion 211 of the guide rail 210.

(22) In this way, the arm 130 rotates as the door 310 is opened, and according to the rotating arm 130, the transfer apparatus 220 slides along the guide rail 210 toward the fixing apparatus 230 of which a position is fixed by the fixing bolt 233.

(23) The transfer apparatus 220 sliding in a direction at which the fixing apparatus 230 is positioned is connected to the fixing apparatus 230 at some time and fix the door 310.

(24) More specifically, if the roller 221 of the sliding transfer apparatus 220 is coupled to the fixing apparatus 230 and touches the elastic piece 241 of the protruded clip 240, the elastic piece 241 gapes open and the roller 221 passes through the opening 243 between the gaping elastic pieces 241 and slides up to the trapping portion 245.

(25) The roller 221 sliding to the trapping portion 245 in this way has strong bearing power and is prevented from shaking because the elastic piece 241 positioned at the trapping portion 245 is formed to surround the outside in a center of the roller 221 and holds the transfer apparatus 220 not to slide any more, and the fixing apparatus 230 and transfer apparatus 220 are adhered and support each other.

(26) Also, due to the above, the arm 130 connected to the arm connection portion 223 of the transfer apparatus 220 does not also rotate, and thus fixing the door 310 in an open state is maintained.

(27) Further, if a position of the fixing apparatus 230 fixed to the sliding portion 211 of the guide rail 210 with the fixing bolt 233 is controlled to reduce or extend a whole moving distance from the transfer apparatus 220, an angle at which the door 310 fixed to maintain an open state when the transfer apparatus 220 is connected to the fixing apparatus 230 is opened may be controlled and fixed to be close to an aright angle in a criterion of the door frame 300 or at any angle.

(28) As the above, the elastic piece 241 which is divided into the left and the right and faces each other surrounds and holds the outside in a center of the roller 221, the transfer apparatus 220 and fixing apparatus 230 are adhered to each other to be stably fixed, and in a process that the transfer apparatus 220 and fixing apparatus 230 are connected or separated, friction occurring due to direct contact is minimized and thus, noise and vibration may be reduced.
