Description

자력의 무단 조절구조가 마련된 유리창용 세척장치Glass window cleaning device with self-regulating structure
본 발명은 유리창용 세척장치에 관한 것으로, 더욱 상세하게는 유리창의 내벽과 외벽에 위치되는 실내 세척구와 실외 세척구에 각각 자석을 설치하여, 이들 실내 세척구와 실외 세척구가 자력에 의해 함께 이동되면서 유리창의 내벽과 외벽을 세척하도록 구성된 형태의 유리창용 세척장치에 있어서의, 유리창의 두께에 따른 자력조절구조의 개량에 관련된 것이다.The present invention relates to a window cleaning device, and more specifically, the magnets are installed in the indoor and outdoor cleaning ports located on the inner and outer walls of the glass window, respectively, while these indoor and outdoor cleaning devices are moved together by magnetic force. In a window cleaning apparatus of a type configured to clean an inner wall and an outer wall of a window, the present invention relates to an improvement of a magnetic force control structure according to the thickness of a window.
아파트, 빌딩, 고층건물 등에 설치된 유리창의 외측면에는, 먼지나 이물질 등을 포함하는 각종 오염물질이 부착되어서 채광성과 건물의 전체적인 미관을 해치게 된다.On the outer surface of the windows installed in apartments, buildings, high-rise buildings, etc., various contaminants, including dust and foreign matters, are attached to impair the light and the overall aesthetics of the building.
일반적으로는 유리창의 외측면에 부착된 위와 같은 오염물질을 제거하기 위해 작업자가 유리창의 밖에 매달려 닦거나 유리창을 떼어 내어 닦고 있으나, 이러한 청소작업은 번거로울 뿐만 아니라 위험하기까지 하다.In general, in order to remove such contaminants attached to the outer surface of the glass window, the worker hanging outside of the glass window to wipe or remove the glass window, but such cleaning is cumbersome and dangerous.
이러한 문제점을 해소하기 위해 유리창의 외측면을 실내에서 청소할 수 있는 유리창 세척장치에 대한 개발이 이루어져 있다. 예컨대 대한민국 실용신안 등록공보 제 354932호에는, 스펀지와 와이퍼가 마련된 실내 세척구와 실외 세척구에 각각 자석을 설치하여, 이들을 유리창의 내부와 외부에 각각 위치시킨 후, 실내 세척구와 실외 세척구가 자력에 의해 서로 연동하여 이동되면서 유리창의 내부와 외부를 동시에 세척하도록 구성된 유리창 세척장치가 개시되어 있다.In order to solve this problem, the development of a window cleaning apparatus that can clean the outer surface of the glass window in the room has been made. For example, in Korean Utility Model Registration No. 354932, magnets are installed in indoor and outdoor cleaning devices equipped with sponges and wipers, and they are placed inside and outside glass windows, respectively. By moving in conjunction with each other by the glass window cleaning device configured to simultaneously clean the inside and the outside of the glass window is disclosed.
이러한 유리창용 세척장치에 의해 유리창의 세척작업을 보다 안전하고 또 저렴하게 구현하는 것이 가능하게 되었다.Such a window cleaning device has made it possible to implement a safer and cheaper window cleaning.
그런데, 상기와 같은 형태의 유리창 세척장치에 있어서는, 용이하고 안전한 세척작업을 위해서는 유리창에 사용되는 유리의 두께에 따라 자력의 세기를 조절이 가능하도록 구성할 필요가 있다. 따라서, 종래의 유리창용 세척장치들에는 통상 상기 자력의 세기를 조절하기 위해 자석의 간격을 조절할 수 있는 구조가 마련되어 있다. By the way, in the window cleaning apparatus of the above type, for easy and safe cleaning operation, it is necessary to configure the strength of the magnetic force according to the thickness of the glass used in the glass window. Therefore, conventional window cleaning devices are provided with a structure that can adjust the spacing of the magnet in order to control the strength of the magnetic force.
이러한 자력의 세기를 조절하기 위한 구조로서는, 예컨대 실내 세척구의 자석 수용부에 자석이 설치된 지지부재와 고정판을 승강구조로 설치하고, 이 지지부재와 고정판의 양편에 쐐기형의 위치 조절부재를 설치하여, 쐐기형의 위치 조절부재의 진입여부에 따라 지지부재의 위상이 변화되어 실내 세척구와 실외 세척구 사이의 자력이 조절되도록 한 구조가 알려져 있다.As a structure for adjusting the strength of the magnetic force, for example, a support member and a fixing plate provided with magnets are provided in a lifting structure, and a wedge-shaped position adjusting member is provided on both sides of the support member and the fixing plate. It is known that the structure of the support member is changed according to whether or not the wedge-shaped position adjusting member enters, so that the magnetic force between the indoor and outdoor washing holes is controlled.
그러나 이러한 형태의 자력 조절구조는, 자력의 조절범위가 쐐기형의 위치 조절부재의 택일적인 진입 또는 배출에 따라 자력 조절범위가 획일적으로 제어되므로, 그 사이의 미세한 중간치의 자력의 세기를 설정하기 어려워 다양한 규격으로 제작되는 창유리에 공용하기는 사실상 어렵다. However, in this type of magnetic force control structure, since the magnetic force control range is uniformly controlled according to the alternative entry or discharge of the wedge-shaped position control member, it is difficult to set the strength of the magnetic force of the minute intermediate value therebetween. It is practically difficult to share with panes made of various standards.
한편, 대한민국 등록실용신안공보 제438170호에는, 승강구조로 설치된 자석을 나사산이 형성된 조절볼트를 이용하여 승강시킴으로써 무단으로 자력을 조절할 수 있는 형태의 자력조절구조를 갖는 유리창 세척장치가 개시되어 있다. On the other hand, Republic of Korea Utility Model Publication No. 438170, there is disclosed a window cleaning device having a magnetic force control structure of the type that can be adjusted steplessly by raising and lowering the magnet installed in the lifting structure by using the adjustment bolt formed with a screw thread.
이러한 형태의 자력조절구조를 채용할 경우, 상술한 쐐기형 위치조절부재를 구비한 형태에 비해 자력을 정밀하게 조절할 수 있는 장점은 있으나, 자석의 승강을 케이스의 상측면에 돌출하여 결합된 조절볼트의 체결량에 의해 조절되도록 구성되어 있어, 부피가 비대해지고 조작이 어려우며, 나사산의 마모, 요동의 발생 등에 의해 내구성이 떨어지고 작업의 안정성이 떨어지는 문제점이 있다. In the case of adopting this type of magnetic force control structure, there is an advantage in that the magnetic force can be precisely controlled compared with the above-described wedge-shaped position adjusting member, but the control bolt coupled by protruding the magnet lift on the upper side of the case It is configured to be adjusted by the tightening amount of, the volume is enlarged and difficult to operate, there is a problem that the durability is lowered due to the wear of the thread, the generation of swing, etc., and the stability of the work is inferior.
