1. Field of Invention
The present invention relates to a manual window regulator device, and more particularly, to a manual window regulator device capable of preventing sliding of glass outside a vehicle.
2. Description of Related Art
Generally, a drive unit of a manual window regulator is provided with a brake function so as to raise or lower glass by handle manipulation inside a vehicle and so as not to directly move the glass outside the vehicle.
The brake function according to the related art as described above is implemented using frictional force between a steel housing and a brake spring. However, since the friction force is used, a problem such as insufficient braking force or noise due to friction has been continuously generated.
Given the above background, there is a need to solve at least some or all of the above-mentioned problems occurring in the prior art while advantages achieved by the prior art are maintained intact.
The information disclosed in this Background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.
Various aspects of the present invention are directed to provide a manual window regulator device capable of increasing braking force and preventing generation of noise by implementing a brake function using a roller.
Various aspects of the present invention provide a manual window regulator device including a drum, handle shafts provided at both sides of an inner portion of the drum and each handle shaft including a catching part protrudedly formed at an inner side thereof, a glass shaft rotatably provided substantially at the center of the drum and fixed to the catching parts of the handle shafts while being caught by the catching parts at time of a left or right turn, and roller parts provided one o more of the drum, and fixing the handle shafts while being fitted between the handle shafts and the drum at time of rotation of the handle shafts.
Each roller part may include a roller and a roller guide in which the roller is rotatably provided.
When the glass shaft is rotated, the roller parts may be gradually fitted between the glass shaft and the drum, thereby stopping further rotation of the glass shaft.
When the handle shaft is rotated, the handle shafts may simultaneously push both of the glass shaft and the roller parts, such that the glass shaft and the roller parts may be rotated together with the handle shafts.
The drum may be substantially circular. Each handle shaft may have a curve surface on an outer side thereof and a substantially vertical surface on an inner side thereof. The catching part may have inclined surfaces on both sides thereof.
The methods and apparatuses of the present invention have other features and advantages which will be apparent from or are set forth in more detail in the accompanying drawings, which are incorporated herein, and the following Detailed Description, which together serve to explain certain principles of the present invention.
The above and other features of the present invention will now be described in detail with reference to certain exemplary embodiments thereof illustrated in the accompanying drawings which are given herein below by way of illustration only, and thus are not limitative of the present invention, and wherein:
Reference will now be made in detail to various embodiments of the present invention(s), examples of which are illustrated in the accompanying drawings and described below. While the invention(s) will be described in conjunction with exemplary embodiments, it will be understood that present description is not intended to limit the invention(s) to those exemplary embodiments. On the contrary, the invention(s) is/are intended to cover not only the exemplary embodiments, but also various alternatives, modifications, equivalents and other embodiments, which may be included within the spirit and scope of the invention as defined by the appended claims.
A manual window regulator device according to various embodiments of the present invention is a component or device for preventing rotation of a glass shaft outside a vehicle by braking force through a mutual catching and fitting phenomenon of the glass shaft, a handle shaft, and a roller part to solve a problem that the glass is raised or lowered, thereby providing stable braking force and preventing generation of noise.
A manual window regulator system according to various embodiments of the present invention, which is to raise or lower glass inside the vehicle, is configured to include a rail 10 provided at a door, a clamp 20 raised or lowered along the rail 10 and mounted with glass, and a manual window regulator device 40 pulling or releasing a cable 30 by operation of a lever provided inside the vehicle to raise or lower the clamp 20, as shown in
Here, the manual window regulator device according to various embodiments of the present invention is configured to include a drum 100 having a substantially circular shape, handle shafts 200 provided at both sides of an inner portion of the drum 100, respectively, a glass shaft 300 rotatably provided substantially at the center of the drum 100, and roller parts 400 provided at upper and lower portions of the drum 100, respectively, as shown in
The handle shafts 200 according to various embodiments of the present invention are provided at the left and the right of the inner portion of the drum 100, respectively, so as to be movable along an inner peripheral surface of the drum 100, and have an outer side formed with a curve surface so as to be closely adhered to the inner peripheral surface of the drum 100 and an inner side formed with a substantially vertical surface.
In addition, the handle shaft 200 includes a catching part 210 protrudedly formed substantially at the center of an inner side thereof, and the glass shaft 300 is coupled or fixed to the catching part 210 while being caught by the catching part 210.
Both sides of the catching part 210 are formed with inclined surfaces 211, and end portions of the glass shaft are caught by the inclined surfaces 211 so as to be closely adhered thereto to provide stable fixing force and prevent frictional noise from being generated.
The glass shaft 300 according to various embodiments of the present invention is rotatably provided substantially at the center of the drum 100 and includes protrusion parts 310 formed at both end portions of upper and lower portions thereof, respectively, so as to be caught by the catching parts 210.
The roller parts 400 according to various embodiments of the present invention are provided at the upper or lower or upper and lower portions of the drum 100, respectively, and include a roller 410 and a roller guide 420 into which the roller 410 is rotatably inserted.
An operation state of the manual window regulator device according to various embodiments of the present invention having the above-mentioned configurations will be described below.
Operation at the time of manipulating handle is illustrated in
In this case, the roller part 400 and the handle shaft 200 are simultaneously rotated, such that the roller part 400 is not fitted between the drum 100 and the handle shaft 200, thereby making it possible to rotate the glass shaft 300. Due to the rotation of the glass shaft 300, the glass is raised or lowered.
Operation at the time of manipulating glass is illustrated in
That is, a tangent line between the roller 410 and the drum 100 and a tangent line between the glass shaft 300 and the roller 410 form a wedge shape with an angle α, and the roller 410 is fitted into the wedge shape.
Therefore, the further the glass shaft 300 is rotated, the further the roller 410 is fitted between the drum 100 and the glass shaft 300, such that brake is generated. Therefore, the glass shaft 300 may not be rotated.
According to various embodiments of the present invention, a phenomenon that the glass shaft is rotated outside the vehicle is prevented by stable braking force, thereby making it possible to solve a problem that the glass is raised or lowered and prevent generation of noise.
