Description

Supporting device for rolling door

The invention relates to a rolling door supporting device, especially a supporting device that can improve the comprehensive compressive strength of a rolling door, thereby strengthening the disaster prevention and anti-impact support capability of the inside and outside sides of the rolling door, thereby ensuring the security of the rolling door By.

As shown in the first figure, it is a schematic plan view of the closed state of the conventional rolling door 1 with the supporting device 2 installed therein. The rolling door 1 is composed of a plurality of rolling door sheets 10. The top of the rolling door 1 is provided with a rotating shaft. The casing 11 utilizes the rotation of a motor shaft (this is a conventional structure and is not disclosed in the figure) in the casing 11 to wind the rolling door 1 for rolling or opening the door, and the rolling door 1 A door rail 12 is provided on each side so that the rolling door 1 can slide up and down along the door rail 12; when the rolling door 1 is lowered and closed, the bottom of the rolling door 1 will abut against the ground, such a structure of the rolling door 1, When the outer side is blown by strong wind, or when an external force is applied (such as prying from the bottom with a tool), it is easy to be broken and opened, and the anti-theft and wind-proof functions are lost. Therefore, in order to strengthen the support strength of the roll door 1 in the industry , Is to develop a support device 2 that can improve the strength of the rolling door 1.

The above-mentioned supporting device 2 is installed close to the inner side of the rolling door 1, and is mainly composed of a pivot joint 20, a plurality of telescopic links 21 and a transverse link 23. When the supporting device 2 is unfolded (i.e. When the rolling door 1 is in the closed state), the pivot base 20 is located at the central position, and the plurality of telescopic links 21 are centered on the pivot base 20 and distributed radially from the inside to the outside. One end of the telescopic link 21 It is pivotally connected to the pivot joint base 20, and the end of the rod body 22 at the other end of the telescopic link 21 is provided with a pivot end. 221, the pivot end 221 is pivotally connected to both side ends of the lower cross bar 24 and an upper cross bar 25, respectively, and the cross link 23 is laterally fixed to the pivot joint 20, and the two ends of the cross link 23 A guide wheel 231 is provided, and the guide wheel 231 is disposed in a guide rail 121. The supporting device 2 composed above is close to the inner side of the rolling door 1, so that the outer side of the rolling door 1 is attacked by external force (such as strong wind). When it is functioning, it can rely on the supporting device 2 to support the rolling door 1 to improve its compressive strength, thereby ensuring that the rolling door 1 is not damaged or deformed; when the rolling door 1 is opened (as shown in the second figure), The supporting device 2 will cooperate with the rolling door to move upwards at this time. At this time, the lower cross bar 24 and the cross link 23 are moved upward, and the rod body 22 of the telescopic link 21 will be gradually retracted inwardly with the upward movement, until The roll door 1 is received at the uppermost door opening position, and the upper cross bar 25, the lower cross bar 24 and the lateral link 23 of the support device 2 are brought closer together in parallel. The structure of this support device 2 can indeed assist the roll door. 1 Resist the external force from the outside, but from the actual use of examples, there are still shortcomings, as it is As described below:

1. Generally, the source of the external force applied to the rolling door 1 is not limited to the outer side of the rolling door 1. For example, when a fire occurs, the rolling door installed in a building with a fire prevention function is installed. 1 will also face a strong airflow attack on the inner side. This conventional support device 2 is not easy to play the role of resistance and support for the external force from the inner side of the roll door 1.

2. The telescopic link 21 used in the conventional support device 2 has a high material cost, and the cylinder resistance of the telescopic link 21 itself is large during the collapse, which will affect the smoothness of the collapse operation.

In view of this, the inventor of this case has finally completed the rolling door support device of the present invention after countless studies and improvements, that is, the purpose of the present invention is to provide a supporting device that can improve the comprehensive compressive strength of the rolling door, thereby strengthening the rolling door.
