Description

OPENING AND CLOSING APPARATUS IN A SLIDING TYPE OF WINDOW / DOOR SYSTEM}

The present invention relates to a small window system, such as a small window or a small door, more specifically to prevent the vertical reaction force between the door and the rail to move the window smoothly in the direction perpendicular to the longitudinal direction of the rail. The opening and closing device of the US secretary window system which can be.

Generally, a US window system is referred to as a moving window or a moving door (hereinafter referred to as a "mobile window") with respect to a fixed window or a fixed door (hereinafter referred to as a "fixed window") in a relatively fixed position. By sliding relatively).

These secretary window systems include the above-mentioned fixing windows (glass windows are installed inside to become a "fixed window"), moving windows (glass windows are installed inside to become a "moving window"), and a building wall It includes a window frame that is installed and the above-described window frame is installed on its inner surface.

The window frame is provided with a rail portion for guiding the movement of the window sill so that the window sill can be moved. The rail unit includes an upper rail provided at the upper part of the window frame to guide the upper end of the moving window and a lower rail provided at the lower part of the window frame to guide the lower end of the moving window.

In addition, a rail guide portion is installed at the upper part of the window for moving smoothly along the upper rail installed in the window frame, and a roller part is installed at the lower part of the window for moving smoothly along the lower rail installed at the window frame. . Furthermore, glass and a board | plate material are installed inside a window.

On the other hand, such a general window system may further include a sealing member such as a windproof cap or windproof rubber gasket installed between the window frame and the window spear to obtain high quality performance for soundproofing, airtightness, watertightness, insulation, wind pressure resistance and the like. However, the sealing member can improve the performance for soundproofing, airtightness, watertightness, heat insulation, wind pressure resistance, etc., but the sealing effect by the sealing member is not so high due to the limitation of the sealing method. In addition, there is a problem that it is difficult to continuously maintain such a performance as the sealing member deforms or wears over time.

Therefore, in order to make up for the above-mentioned disadvantages associated with sealing, a "lift & sliding type (hereinafter referred to as" LS type ") opening and closing device has been developed as a conventional technique. Hereinafter, the conventional LS type switchgear will be described in detail.

The LS-type opening and closing device is a device for lifting and lowering a heavy weight window when the door part and its associated parts installed under the window window are opened and closed. However, since the concentrated load is applied to the car door, it is not only mechanically disadvantaged, but also has a disadvantage of requiring high strength and high durability for components that must perform the function of lifting and lowering the window for movement. In addition, when the size of the movable window sill increases beyond a certain range, it is difficult to overcome the load burden of the increased size of the movable window sill and the glass installed therein, which limits the applicable window sill size.

In addition, as is known, the LS-type opening and closing device has a structure in which there is no unity because the sealing method to be achieved at the lower part, the side part, and the upper part of one moving window piece is different. Therefore, it is not easy to ensure perfect sealing performance at the corner portions of the window frame and the window frame facing each other due to the different sealing method. Furthermore, since the sealing method at the upper part of the movable window is a method in which the sealing property must be secured only by a weak force in which the upper sealing member is elastically in close contact with the upper guide, it is difficult to achieve full sealing, especially inside and outside the window through the upper guide. There is a problem that is difficult to block the heat transfer.

On the other hand, in order to make up for the disadvantages associated with sealing, as "LS type opening and closing device" and other conventional techniques, "guide device for close closing of the sliding window (hereinafter referred to as" guide device for tight closing ")" Korean Patent Publication No. 10-2004-0075123 published on August 27, 2004 (Application No. 10-2003-0010568, Applicant: Tak Dong Ho) is disclosed in the published patent publication. Hereinafter, a guide apparatus for a conventional close close will be described.

The guide device for the close closing, as shown in Figures 6 to 8 (not attached herein) attached to the above patent publication, and the front end of the sliding window (hereinafter referred to as "moving window pair") and Guide piece is formed at the rear end, and the moving window is pushed back (window and fixed) as the guide window at the front and rear ends is pushed by the corresponding guide rollers (installed on the window frame and the fixing window, respectively) in the final closing stage. And a window for movement in the state in which the window for movement is closed in close contact with the rubber cushion material.

However, when closing the movable window, the guide piece of the movable window is inserted between the roller and the rubber buffer at the end of the window frame, and due to the large frictional force generated, a large force is required to completely close the movable window, and conversely, In order to enjoy all of the fairly large force is required, after this, there is a problem in that a large force is required again to open the movable window while overcoming the frictional force by the reaction force. In addition, in the final section in which the moving window is closed, the moving window and the guide piece slide further in the window frame direction (in the closing direction) while the rubber buffer and the guide piece are in contact with each other, so that the sealing between the rubber buffer and the guide piece is made. As a result, a lateral frictional pressure is applied to the rubber cushion, which has a problem of reducing durability of the rubber sealing material and shortening its lifespan.

Furthermore, even if the technical configuration and the operation state of the flow means shown in the doorway portion of the moving window with reference to FIGS. 9 to 11 attached to the above patent publications, a considerable problem has been expressed.

For example, as described in the detailed description of the present invention, in the case of switching from the closed window to the open state, the inclined configuration of the door lock fastening portion is the center load of the moving window is directed toward the interior and the window It is described that the mobile window can be freely slidable without contact or interference with a sealing means (rubber buffer material) disposed at the rear of the door. However, since the user is indoors, the user located in the room opens and closes the mobile window. It is common to apply a force to the moving window while grasping the handle and pushing the moving window backward. Therefore, when the user applies a force pushing the rear window to the mobile window, there is a problem that the contact friction between the mobile window and the rubber buffer inevitably occurs.

In addition, even when the lower portion of the movable window is inclined toward the interior, it is preferable to design the upper groove of the movable window larger than the lower groove of the movable window in consideration of the ease of inserting the movable window into the window frame or removing the window from the window frame. General technical specifications. Therefore, in the upper portion of the movable window, a gap is generated up and down with the window frame, so that the eccentric effect by the weight of the movable window obtained by the inclined configuration of the door lock fastening portion under the movable window does not occur in the upper portion of the movable window. As a result, the upper part of the movable window is squeaked back and forth through the front and rear gaps of the window frame and the front and rear gaps of the upper part of the movable window (must be the same size as the front and rear gaps at the lower part of the movable window) irrespective of this inclination direction. Another big problem is presented.

On the other hand, in order to compensate for the disadvantages associated with sealing, the "LS type opening and closing device" and the "guide device for close closing" and another conventional technology, the "Arm Rotation & Sliding Type opening and closing device" "Was developed. Hereinafter, a conventional arm rotation and sliding type switching device will be described.

The arm rotation and sliding type opening and closing device has a disadvantage in that the analysis of the load is inevitably disadvantageous because it has a cantilever structure in which a moving window is placed on the arm. Therefore, the size of the mobile window is limited due to the load, and in order to withstand the eccentric load of the mobile window with a large weight through the cantilever structure of the arm, not only the arm but also the high strength of the components such as the roller and the rail In the end, productivity and economics are detrimental, as they require careful handling. In addition, in the arm-type rotating structure, it is common to install the arm only at the lower part of the moving window, and unlike the lower part of the moving window, the upper frame of the moving window configured independently does not work in conjunction until the moving window is completely closed. There is also a problem that the user causes anxiety in operation because it moves independently without moving (the upper frame of the movable window is swung due to wind pressure when a strong wind blows when the movable window is not completely closed).

On the other hand, in order to solve the problems with the above-described conventional LS type opening and closing device, the guide device for close closing and the arm rotation and sliding type opening and closing device, as a conventional technology filed and registered by the present applicant, Korean Patent Registration Publication No. 10-0729222 issued on June 19, 2007 (Applicant: Lee Kwang-Seok, Application No .: 10-2006-0023871, PCT Publication WO 2007/075075) Was initiated. Hereinafter, the opening and closing apparatus of a conventional US window system will be described.

The door open / close device of the U.S. window system provides excellent sound insulation, airtightness, watertightness, insulation, and wind pressure resistance, while simplifying the open / close structure, thereby minimizing the number of components constituting the window system, thereby achieving economical efficiency. Or reduce the cross-sectional profile of a moving window on which the components are installed to provide the stiffness to support the plate and to provide the basic performance required throughout the window system, including soundproofing, airtightness, watertightness, insulation and wind pressure resistance. It is possible to improve the economics by providing a window system that can increase the size of the glass window in terms of the same window frame size, thereby enhancing the lightness and the feeling of opening, and also to install such a window system at the construction site Even when the limit of construction accuracy can be lowered Books will have to be significantly lower construction defect rate.

Hereinafter, referring to FIGS. 1 to 8, the opening and closing device of a conventional US window and window system will be described in more detail.

As shown in Figures 1 to 3, the opening and closing device of the US window system so as to enable the movement of the moving window 40 along the upper rail (11a) and lower rail (11b) installed in the window frame (10). In addition, the rail guides 41a of the rail guide assemblies 41a and 42a on the upper frame 40a of the moving window are mounted on the upper rail 11a and below the lower frame 40b of the moving window. Among the 41b and 42b, the door roller 41b has a structure that meshes with the lower rail 11b. Along with this, the upper frame 40a of the movable window 40 is movably mounted to the rail guide assemblies 41a and 42a on the upper frame 40a of the movable window 40, and the lower frame of the movable window 40 40b has a structure which is movably mounted to the door-wheel part assembly 41b, 42b under the moving window lower frame 40b. Specifically, by the operation of the opening and closing operation means (illustrated as '50' in Fig. 5) installed on the side frame (shown as '40s' in Fig. 5) of the moving window 40, The upper frame 40a and the lower frame 40b of the moving window 40 include a displacement component perpendicular to the moving direction of the rails 11a and 11b of the window frame 10, and includes a front-rear direction (refer to "CL in FIG. 1"). "And" OP "). In addition, a sealing member 30 made of an elastic material or the like is provided with a window frame 10 (or a fixed window sill (Fig. 7) so that it is sealed under pressure of the same magnitude in the direction perpendicular to the whole by the movement of the window sill 40. Shown by reference numeral 20 ') and the window sash 40 for movement.

Hereinafter, referring to FIGS. 2 to 4, the detailed configuration and operation principle of the moving window 40 are moved in a direction perpendicular to the moving direction of the rails 11a and 11b.

Figure 2 is a perspective view showing the main portion before the moving window is moved in a direction perpendicular to the rail travel direction, Figure 3 is a view showing a state in which the moving window is pressed in a direction perpendicular to the rail travel direction to press the sealing member. It is a principal part perspective view, and FIG. 4 is a longitudinal cross-sectional view which shows the state before and the moving window frame was moved to the perpendicular direction perpendicular | vertical with respect to the rail advancing direction.

As shown in FIGS. 2 and 3, when the door part assemblies 41b and 42b are pushed by a moving force Fp including a direction component parallel to the traveling direction of the lower rail 11b, the door part assembly 41b, The inclined guide groove 43b formed inclined to the upper plate 42b of the surface 42b (a set angle inclined with respect to the longitudinal direction of the lower rail in plan view) and downward from the bottom of the lower frame 40b of the moving window 40. By the inclined connection structure with the protruding guide protrusion 44b, the moving force Fp is decomposed into two components, horizontal component force Fh and vertical component force Fv. At this time, the vertical component force Fv acting in the direction perpendicular to the rail traveling direction is in a direction in which the door roller 41b at the lower part of the door roller assembly 41b and 42b is perpendicular to the rail traveling direction in the lower rail 11b. Is constrained to escape and cannot have a displacement perpendicular to the rail travel direction, so the direction of the force is reversed. The vertical force and the magnitude of the force are the same, but the reaction force in the opposite direction is equal to the width D of the inclined guide groove 43b in the front and rear direction perpendicular to the rail traveling direction of the lower frame 40b of the moving window 40. It will act to move. The use of such a forward and backward movement is the main principle of the opening and closing device of the US-based window and door system.

On the other hand, Figure 5 is a perspective view of the main part showing an embodiment of the opening and closing operation means of the opening and closing device of the conventional US window and door system, Figure 6 is a perspective view showing the main configuration and operation state of Figure 5, and Figure 7 Figure 5 is a view showing a state before and after the movement window is moved in a direction perpendicular to the longitudinal direction of the rail in the opening and closing device of the US window and window system to which the opening and closing operation means is applied.

In particular, FIGS. 5-7 illustrate one embodiment of the opening and closing actuating means for implementing the operating principle of the prior art shown in FIGS. 1 to 4 in detail. Furthermore, more various embodiments of such opening and closing operation means are described in Korean Patent Registration Publication No. 10-0729222 (corresponding to PCT Publication No. WO 2007/075075) as a prior art filed and registered by the present applicant, and Korean Patent Registration Publication No. 10-0671256 issued January 19, 2007 (corresponding to PCT Publication WO 2007/139354), and Korean Patent Registration Publication No. 10-0729223 published June 19, 2007 (PCT Publication WO 2007/139355), one of which is the same as the sliding opening and closing actuating means 150 shown in FIG. 8, which will be described in detail. A side sliding bar 150c installed in the longitudinal direction so as to be movable up and down on the frame, a rotating handle 150h installed to apply an operating force for moving the side sliding bar 150c up and down, and Gear mechanisms 150L and 150P installed to convert the rotational movement of the handle 150h into the vertical reciprocating motion of the side sliding bar 150c and the upper and lower ends of the side sliding bar 150c are connected to the moving window window ( An elastic slider 150S for transmitting the reciprocating motion to the upper or lower portion of the 40, and the upper and lower sliding bars 151a which are horizontally installed on the upper and lower portions of the moving window window 40 so as to cooperate with the elastic slider 150S. And 151b and connecting rod members 152a and 152b for linking the upper and lower sliding bars 151a and 151b to the lower plate 42a of the rail guide assembly and the upper plate 42b of the car door assembly, respectively. It is made to include. In the case of the embodiment shown in FIG. 8, unlike the embodiment shown in FIG. 6, when the rotary knob 150h is operated, the lower plate 42a of the rail guide assembly of the moving window window and the upper plate 42b of the door block assembly are respectively. The generated horizontal displacements act in opposite directions to each other in the direction of the inclined guide grooves 43a1 and 43a2, 43b1 and 43b2 and in the inclined guide grooves 43a1 and 43a2, 43b1 and 43b2, respectively. Initial positions of the guide protrusions 44a and 44b to be fitted are formed to be opposite to each other.

However, according to the prior art having the structure described above, when the door-to-wheel part assemblies 41b and 42b are pushed with a moving force Fp including a direction component parallel to the traveling direction of the lower rail 11b, the vehicle is perpendicular to the rail traveling direction. The above-mentioned reaction force is applied between the doorway 41b and the lower rail 11b by the vertical component force Fv acting in the direction, which ultimately acts as a large friction force between the doorway and the rail and is horizontal. The component force Fh may impede the movement of the doorway along the rails. That is, even if the door assembly is pushed using the opening and closing operation means, there may be a problem in that the door does not move on the rail due to the friction force that may be generated between the door and the rail by the aforementioned reaction force.

Further, in view of the fact that the load of the mobile window sill 40 applied to the windows of the system type is much larger than the load of the mobile window sill applied to the windows of the general type due to the configuration of the opening and closing operation means 50 and the like, the mobile window sill In the process of vertical movement of the 40, a large frictional resistance is applied between the lower frame 40b of the moving window 40 and the top plate 42b of the door-to-door assembly 41b, 42b. It can be an obstacle to smooth vertical movement.
