Description

Door closer

本發明是關於一種關門器，特別是關於一種具有滑軌之關門器。The present invention relates to a door closer, and more particularly to a door closer having a slide rail.

習知的關門器具有一復位裝置、一連桿、一滑塊及一滑軌，通常該門弓器安裝於一門板，該滑軌安裝於一門框，該滑塊設置於該滑軌，該連桿連接該門弓器及該滑塊，該復位裝置用以帶動該連桿，以使該門板在被開啟時，能藉由該復位裝置及該連桿作動而自動關閉該門板。The conventional door closer has a reset device, a connecting rod, a slider and a slide rail. Usually, the door archer is mounted on a door panel. The slide rail is mounted on a door frame, and the slider is disposed on the slide rail. A rod is coupled to the door archer and the slider, and the resetting device is configured to drive the connecting rod to automatically close the door panel by the resetting device and the connecting rod when the door panel is opened.

當該門板開啟時，該復位裝置會隨著該門板移動，由於該連桿連接該復位裝置及該滑塊，因此，該滑塊會被該連桿帶動，而朝向一第一方向移動，相對地，當該門板關閉時，該復位裝置會帶動該連桿，且該連桿會帶動該滑塊朝向一相反該第一方向的第二方向移動而使該門板關閉。When the door panel is opened, the resetting device moves along with the door panel. Since the connecting rod is connected to the resetting device and the slider, the slider is driven by the connecting rod and moves toward a first direction. And when the door panel is closed, the resetting device drives the connecting rod, and the connecting rod drives the sliding rod to move in a second direction opposite to the first direction to close the door panel.

由於該復位裝置及該連桿作動而使得該門板常態地被保持在關閉狀態，因此欲使該門板保持在開啟狀態時，通常會持續施力於該門板或使用石塊等物體去擋止該門板，以避免門板被該復位裝置帶動而關閉，但相對地造成了使用者的不便。Because the reset device and the connecting rod actuate, the door panel is normally kept in a closed state. Therefore, when the door panel is to be kept in an open state, the door panel is generally continuously applied to the door panel or an object such as a stone block is used to block the door panel. The door panel prevents the door panel from being closed by the resetting device, but relatively inconvenience to the user.

本發明之主要目的在於門板開啟時，可藉由設置於滑軌中之固定件擋止滑塊的移動，使得門板可維持開啟的狀態。The main purpose of the present invention is that when the door panel is opened, the movement of the slider can be stopped by the fixing member disposed in the slide rail, so that the door panel can maintain the open state.

請參閱第3及6圖，當該門板210被開啟時，該復位裝置150帶動該連桿140，同時該連桿140帶動該滑塊130由該滑軌110的該第一端111朝向該第二端112移動，並使該滑塊130抵觸該固定件120之該擋止部122。Referring to FIGS. 3 and 6, when the door panel 210 is opened, the reset device 150 drives the link 140, and the link 140 drives the slider 130 from the first end 111 of the slide rail 110 toward the first The two ends 112 move and the slider 130 is in contact with the stopping portion 122 of the fixing member 120.

請參閱第3、6及7圖，當該抵觸件133抵觸該固定件120之該導引面125時，該抵觸件133會被該擋止部122推擠，而使得該抵觸件133沿著該通孔134之一縱軸方向移動並縮入該導引槽131中，在本實施例中，由於該基部133b被限制於該導引槽131中，因此可避免該抵觸件133縮入該導引槽131時發生偏斜而卡止於該導引槽131。 Referring to FIGS. 3, 6 and 7, when the abutting member 133 is in contact with the guiding surface 125 of the fixing member 120, the abutting member 133 is pushed by the stopping portion 122, so that the abutting member 133 is along One of the through holes 134 is moved in the longitudinal direction and retracted into the guiding groove 131. In this embodiment, since the base portion 133b is confined in the guiding groove 131, the contact member 133 can be prevented from being retracted into the guiding groove 131. When the guide groove 131 is deflected, it is locked to the guide groove 131.

請參閱第5、8及9圖，當該滑塊130通過該固定件120時，該抵觸件133受到該彈性件132之頂推而延著該通孔134之該縱軸方向移動，以使該凸出部133a凸出於該通孔134，該凸出部133a並抵觸於該擋止部122的該擋止面124，因此該滑塊130被該固定件120擋止而不會滑移，以達到使該門板210保持於開啟的狀態，而不會自動關閉。 Referring to FIGS. 5, 8 and 9, when the slider 130 passes through the fixing member 120, the abutting member 133 is pushed by the elastic member 132 to move in the longitudinal direction of the through hole 134, so that The protruding portion 133 a protrudes from the through hole 134 , and the protruding portion 133 a abuts against the blocking surface 124 of the stopping portion 122 , so that the slider 130 is blocked by the fixing member 120 without slipping In order to maintain the door panel 210 in an open state without automatically closing.

請參閱第5、6及7圖，該抵觸件133之該凸出部133a具有一斜面133c，該斜面133c及該表面123之間形成有一第三夾角θ 3，在本實施例中，該第一夾角θ 1與該第三夾角θ 3之間具有一差值，其中該斜面133c與該擋止面124之間的接觸面積大小與該抵觸件133通過該固定件120的難易程度及通過接觸時所發出的噪音相關；接觸面積小，該抵觸件133較容易通過該固定件120且發出噪音較小，反之則不易通過且相對來說發出噪音較大。當該差值為0度時，接觸面積大令該抵觸件133不易通過該固定件120且發出噪音較大，當該差值大於20度時，該擋止面124可能無法發揮擋止效果，因此，該差值介於0度至20度之間，可降低噪音又兼具擋止效果，此外，在本實施例中，較佳的，該第三夾角θ 3大於該第一夾角θ 1，可避免該抵觸件133之該斜面133c與該擋止面124之間的摩擦力過大，而造成該抵觸件133或該固定件120損壞。 Referring to Figures 5, 6 and 7, the projection 133a of the contact member 133 has a slope 133c, and a third angle θ 3 is formed between the slope 133c and the surface 123. In this embodiment, the A difference between the angle θ 1 and the third angle θ 3 , wherein the contact area between the slope 133 c and the stop surface 124 is different from the ease with which the contact member 133 passes through the fixing member 120 The noise generated when the contact is small; the contact area 133 is relatively easy to pass through the fixing member 120 and emits less noise, and vice versa, it is difficult to pass and relatively loud. When the difference is 0 degrees, the contact area is large, so that the contact member 133 does not easily pass through the fixing member 120 and emits a large noise. When the difference is greater than 20 degrees, the blocking surface 124 may not be able to exert a blocking effect. Therefore, the difference is between 0 and 20 degrees, which can reduce the noise and the blocking effect. In addition, in the embodiment, preferably, the third angle θ 3 is greater than the first angle θ 1 The friction between the inclined surface 133c of the contact member 133 and the blocking surface 124 is prevented from being excessive, and the contact member 133 or the fixing member 120 is damaged.
