Description

Roll reduction device for roll screens {The roll screen for a reduction device}

The present invention relates to a deceleration device that does not work when the roll screen wound around the take-up tube is artificially pulled down and is released, and is operated only when the roll screen, which is released at the moment of releasing the pull, is wound on the take-up tube again. The torsion spring wound on one side of the inner shaft of the tube is applied to the resilient device of the roll screen, which is activated only when the roll screen is rolled up again according to the elasticity of the torsion spring. The roll screen released from the winding tube by reducing the rotational speed of the winding tube firmly connected to the reduction case member through the improved deceleration performance made through the resistance generated during the flow of oil by the centrifugal force of the reduction member rotating inside the member. When it is wound rapidly again in this winding pipe, it greatly reduces the winding speed. As a result, the use of the roll screen is more secure, and also relates to a roll screen reduction device for preventing noise during use to create a quiet and comfortable indoor environment.

In general, a roll screen used as a insect screen or a sun shader is wound rapidly according to the elasticity of the torsion spring wound on a rotating shaft inside one side of the winding tube when the roll screen is unwound from the winding tube. Not only does it surprise you, it also has the disadvantage of producing loud noises during use.

For example, the roll screen is rapidly wound on the take-up tube by the elastic force of the torsion spring under one side torsional pressure inside the take-up tube. As the user is surprised, the acceleration causes a severe noise during use while the handle bar at the bottom of the roll screen hits the case receiving the take-up pipe.

Therefore, as an example of a roll screen reduction device for solving this problem, Patent Registration No. 909039 (hereinafter referred to as "pre-registration patent") has been pre-registered by the present applicant.

The rotational speed of the winding tube that is in reverse rotation by the elastic force of the torsion spring while being in close contact with the inner diameter of the tube is decelerated by the deceleration rotating body.

However, the pre-registered patent is to decelerate the rotational speed of the winding pipe reversely rotated by the elastic force of the torsion spring through the deceleration rotating body to decelerate for a certain period when the roll screen is rolled up upwards. The device assembly is a method in which a plurality of gears (speed gears, one-way gears, cam gears, etc.), ratcheting means, and one-way spool are intricately related to each other in the deceleration rotating body. When deceleration, there was a risk of causing malfunction, and since the deceleration rotor accommodated in the narrow space inside the winding pipe has many restrictions on its size, a complex part is assembled to the deceleration rotor that is restricted in size as described above. Not only was it very difficult to produce, but it also resulted in a costly closure that was costly to produce. There were various problems such as failure of the service life due to the complexity and the long life span.

The present invention has been made in order to solve the problems that have not been solved in the prior registration device and the applicant's prior registration patent as described above, the deceleration through the reduction case member accommodated in the winding pipe inside the reduction case member By reducing the rotational speed of the winding tube which is firmly connected to the reduction case member through the improved deceleration performance made through the resistance generated during the flow of oil by the centrifugal force of the rotating reduction member, the roll screen released from the winding tube is again When winding up, the winding speed is greatly reduced so that the deceleration performance is further improved than the prior art and the applicant's pre-registration deceleration device, so that the roll screen is smoothly rolled up during the whole winding section of the winding tube, so that its use is not only safer. The noise is prevented during use to create a quiet and pleasant indoor environment. And as the main purpose, another object of the present invention is a further object of the deceleration device of the roll screen with improved economics by reducing the manufacturing cost as well as reduce the failure rate to simplify the structure of the reduction unit to provide.

The present invention for achieving the above object is connected to the groove formed in the four sides of the winding pipe accommodated in the winding pipe, and is firmly connected to each other, the through hole in the front and the receiving hole in the rear A deceleration case member formed; The connecting shaft is inserted through the receiving hole of the reduction case member so that once the connecting shaft is exposed through the front through hole of the reduction gear case member, the support shaft is integrally extended on the same line as the other end of the flange integrally extending from the connecting shaft. A one-way member; A spring member inserted in close contact with the outer diameter of the tip of the support shaft; A reduction member configured to receive a support shaft therein through the tip opening portion, the opening portion being in close contact with the rear surface of the flange and having an oil injection hole formed in the rear blocking portion; A sealing cap forcibly fitted into the receiving hole of the reduction case member; A connecting member connecting a connecting shaft exposed through the front through hole of the reduction case member and a rotating shaft wound around a torsion spring received at one side of the winding tube; It is characterized in that the reduction device is made.

The one end of the flange of the one-way member shaft is formed with a stepped portion in close contact with the inner surface of the through-hole of the reduction case member, characterized in that the sealing O-ring is fitted in the stepped portion.
