Description

Damper assembly mounted on sliding windows

The present invention relates to a damper assembly mounted on a sliding type window that is applied to a system window or a lift sliding window and induces the window to close slowly and smoothly through a stable damping operation even when the distance between the window and the window frame is changed.

A sliding window or a sliding door is a sliding type window that is inserted into an upper frame and a lower frame fixed to a structure and slides laterally to open and close a partitioned space.

The above sliding type windows have a structure that opens and closes by sliding the door leaf, and has a characteristic that sliding by rollers is performed smoothly and quickly with little force without deceleration due to the improvement of window technology.

However, windows that become increasingly heavy due to insulation, etc., are accelerated to excessive speed during opening and closing due to their inertial force, and collide with side windowsills or other windows (windows) to generate impact noise or cause damage, and cause damage to fingers or fingers. There is a problem that frequently causes safety accidents in which a body such as a toe is caught in a door gap.

In order to prevent this problem from occurring, a damper structure technology has been developed so that the window is gradually closed by a damping operation during the closing operation of the window. As an example, Korean Patent Registration No. 10-1559676 discloses a technology for a slider shock absorber with an extended damper storage unit.

The patent is fixed to the door frame of the sliding door and has a guide groove for guiding the movement of the hook, a case having a damper compartment, a damper installed in the damper compartment of the case, and a slider mounted on the rod end of the damper and including a sliding door. It includes a hook and a tension spring, one end of which is fixed to the hook and the other end of which is fixed to the case, for the return of the hook and damper that are fixed and engaged by inserting the latch.

In the above patent, the door is gradually closed by the damper while the latch is engaged with the hook during the closing operation of the door.

However, the above patent has a problem in that the normal operation is possible while the latch is engaged with the hook only when the distance between the window and the window frame is constant along the sliding direction of the window.

That is, since the above patent has a structure in which the hook and the latch are fixed to each other at a constant position, when the distance between the window and the window frame is not constant due to various factors such as long-term use, external shock, or foreign matter being caught, the hook As the height is relatively low, there is a problem that the latch passes through without being caught on the hook or the hook collides with the case because the height of the hook is relatively high.

Moreover, in recent years, a system window in which the window itself moves up or down according to the rotational motion of the handle (handle) is used to open and close the sliding system. The structure of the conventional fixed hook and latch was not easily performed during the movement of the window or door and did not perform a proper damping operation.

In order to solve this problem, Patent Registration No. 10-2310039 is disclosed, and in the patent, a long hole is formed in a bracket fixed to a window, and then a movable body in which a damper is installed is movably coupled so that the window can be raised and lowered. At the same time, it has a structure in which the hook member is engaged with the fixing protrusion while moving up or down along the long hole.

However, the above patent simply consists of a structure in which the movable body moves up and down while being coupled to the long hole of the bracket, so there is a limit to closely operating when the window moves up and down, and the movable body maintains the fastened state to the fixed protrusion. According to the structure in which the window is lowered in the state in which it is being used, when the fastening protrusion of the hook member is worn out due to long-term use, there is a possibility of being easily separated.

In addition, in the case of system windows, there is a difference in the distance between the window and the window frame depending on the size or structure of the window, and there may be a difference in the vertical movement distance of the window. When configured as a state, it is difficult to apply to all windows and there is a possibility that it may not work properly.

In addition, the above patent fixes the support frame to the window frame. When there is a difference in size or structure of the window frame or an obstacle exists on the inner side of the window frame, the support frame is not installed in the correct position by changing the fixing position of the fixing means (piece, etc.). There is a problem that the damping operation cannot be performed, and there is a possibility that a stable and smooth damping operation may not be performed due to a problem in operation.

Hereinafter, a damper assembly mounted on a sliding type window according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown, the damper assembly mounted on the sliding window according to the present invention reduces the sliding speed when the window slides and closes, thereby inducing the window to close gradually.

The present invention is a case 10 installed on one side of the upper part of the window, a damping unit 20 installed on the case 10, a fixing plate 30 installed on the inner surface of the window frame, and a fixing plate 30 A pivoting locking piece 40 hinged at the bottom and installed to rotate downward, an elastic spring 50 for imparting elastic force to the pivoting locking piece 40, and a guide surface 60 inclined at one end of the case 10 ) is made up of

The case 10 is installed to a certain length on one side of the upper part of the window, and on one side of the side, a guide groove 11 is formed to guide movement in a state in which the hook member 23 is bound to one or both sides, and on one side of the upper surface A hook member moving hole 12 is formed so that an upper part of the hook member 23 that is formed to be opened and moves along the guide groove 11 can be moved while being exposed.

At this time, the case 10 may be formed to be separated into two units as shown in FIG. 2 and coupled to each other with bolts or the like as shown in FIG.

The guide groove 11 is formed to have a straight section of a certain length and a curved section bent at a certain angle at the end of the straight section. The curved section is preferably formed by bending at an angle of 90 ° or more so that the hook member is not easily separated from the hooked state.

The guide groove 11 may be formed through the side surface of the case 10 or formed to a certain depth on the inner surface of the case. In the accompanying drawings, it is shown that guide grooves 11 are formed to pass through both sides of the case 10, respectively.

On the other side of the upper surface of the case 10, a horizontal guide surface 13 is formed flat to the hook member moving hole 12.

The horizontal guide surface 13 is a part for guiding the rotation locking piece 40 guided to the guide surface 60 to move while being elastically supported with the movement of the window during the closing operation of the window, and on the horizontal guide surface 13 It serves to guide the hook member to be accurately bound to the hook member exposed through the hook member moving hole 12 in a supported state.

The damping unit 20 is installed inside the case 10 and is rotatably coupled to the damper 21 installed to reduce the speed of the window being closed and to the end of the operating rod of the damper 21 It is composed of a hook member 23 to be.

The hook member 23 is provided so as to be moved along the guide groove 11 in a state where one side of the upper portion is caught on the rotational locking piece 40 when the window is opened or closed.

On both sides of the hook member 23, fitting protrusions 28 are formed with a certain length so as to move along the guide groove in a state of being inserted into and bound to the guide groove 11.

The fitting protrusion 28 guides the rotation of the hook member as well as the movement of the hook member 23 while moving not only in the straight section of the guide groove 11 but also in the curved section.

Here, on one side of the hook member 23, through holes 24 are formed in the left and right side directions, and on the other side of the hook member 23 facing the direction in which the damper 21 is provided, an operating rod of the damper ( The rod fitting hole 25 is formed to communicate with the through hole 24 so that 21a) is inserted.

The rod fitting hole 25 is formed to gradually expand from one side portion communicating with the through hole 24 to the other side portion into which the operating rod is inserted. The reason is that when the hook member is moved from the straight section of the guide groove to the curved section or from the curved section to the straight section, as it is rotated at a certain angle, the hook member is inserted into the rod fitting hole and fixed. This is to ensure that the member rotates smoothly.

The operating rod 21a inserted through the rod fitting hole 25 to reach the through hole 24 is fixed by the rod fixture 22 inserted into the through hole 24.

At this time, guide protrusions 22a are formed on both sides of the rod fixture 22 to be moved along the straight section in a state of being inserted into and bound to the straight section of the guide groove 11.

Therefore, the operating rod 21a is moved only in the same direction as the straight section of the guide groove via the rod fixture 22 bound to the straight section of the guide groove 11, so that the damper can be stably moved without moving. that can be operated.

The fixing plate 30 is formed to have a certain length and is coupled to the inner surface of the window frame facing the upper side of the window in which the case 10 is installed, and the lower one side is hinged for hinge coupling of the pivoting piece 40 Bracket 31 is formed by protruding.

This fixing plate 30 is coupled and fixed to the window frame by a fixing piece 70, and fixing holes 35 are formed on one side and the other side of the longitudinal direction of the fixing plate 30 for the coupling of the fixing piece 70, respectively. do.

At this time, the fixing hole 35 is formed as a long hole of a certain length so that the fixing position of the fixing piece 70 can be adjusted. A plurality of head seating surfaces 36 are formed in an arc shape to correspond to the inner surface of the head so that the head of the head is seated and the movement is restricted.

The head seating surfaces 36 may be formed to be spaced apart from each other, but it is preferable that the head seating surfaces adjacent to each other are continuously arranged without a separation distance so as to minimize the spacing between the seating positions of the fixing pieces 70 .

Since the head seating surface 36 is formed, the fixing piece 70 inserted into the fixing hole 35 and fixed to the window frame can be stably seated and fixed without shaking or movement, and the fixing piece can be installed in the fixing hole 35. After moving the position of the fixing plate in the inserted state and accurately positioning it at the set position, it is possible to accurately fix the fixing piece to the corresponding position without moving.

Therefore, even if each manufacturer or product has different specifications, it is possible to mount the fixing plate in the correct position, preventing problems that may occur due to incorrect selection of the fixing location and preventing the change of the fixing location caused by it, It is possible to prevent a plurality of holes from being formed in the window frame due to the change in the fixing position of the fixing piece.

Here, on the inner surface of the fixing hole 35, a movement limiting protrusion 37 is formed at a position corresponding to the gap between the head seating surfaces 36 adjacent to each other.

As the movement limiting protrusion 37 is formed, the body of the fixing piece 70 inserted into the fixing hole 35 is bound, thereby limiting the movement of the fixing piece in the left and right directions, and being fixed to the window frame in that state. It is combined without tilting, making it possible to combine firmly, as well as easy and convenient fixing work. It can be fixed accurately.

In addition, anti-lifting fixing holes 36 are formed on both sides of the middle portion of the fixing plate 30 .

As both sides of the fixing plate 30 are fixed to the window frame by the fixing piece 70, the middle part, that is, the middle part where the pivoting locking piece 40 is formed may be lifted during the fixing process.

Therefore, in order to prevent this lifting phenomenon, the anti-lifting fixing hole 36 is formed, and the middle part of the fixing plate 30 is formed by fitting and combining the fixing means 75 through the anti-lifting fixing hole 36. It can be tightly fixed to the .

In addition, even if a slight movement occurs in the fixing plate fixed by the fixing piece, the fixing plate can be more firmly fixed to the window frame by the fixing means 75 inserted into the anti-lifting fixing hole and fixed to the window frame.

One side of the rotational locking piece 40 is coupled to the hinge bracket 31 with a hinge pin 45 and is provided to rotate downward, and a stopper 41 is formed on the other side of the rotational locking piece 40 to set the maximum It is installed to rotate downward within an angle.

The stopper 41 is composed of a locking jaw protruding a certain length from one end of the rotational locking piece 40, or a part of one end of the rotational locking piece 40 is inclined at a certain angle to make surface contact with the fixing plate 30 As it becomes, it is possible to limit the rotational jampyeon so that it no longer rotates.

In the accompanying drawings, a portion of one end of the rotational locking piece 40 is formed to be inclined at a certain angle, so that rotation is limited while being in surface contact with the fixing plate 30.

An insertion groove 42 is formed on the lower surface of the other side of the rotational locking piece 40 so that the coupling protrusion 27 of the hook member 23 is inserted. A detailed description of the insertion groove 42 will be described later.

And, a guide groove 43 is formed at a certain depth on the lower surface of the other side of the rotational locking piece 40.

The guide groove portion 43 is formed to a certain depth from the end of the rotational locking piece 40 to the insertion groove 42, and the coupling protrusion 27 is not separated by the guide groove portion 43 being formed. It can be smoothly inserted into the insertion groove 42 while being effectively guided without it.

The elastic spring 50 is installed between the rotational engagement piece 40 and the fixing plate 30, and is elastic at the set maximum angle at which the rotational engagement piece 40 can be rotated downward by applying elastic force to the rotational engagement piece 40 at all times. It is a spring to maintain the rotated state.

Such an elastic spring 50 is sufficient if it is a spring capable of imparting elasticity to the rotational engagement piece, and for example, as shown in the accompanying drawings, it can be configured as a compression spring that elastically moves the rotational engagement piece by pressing, and in addition to the hinge It is also possible to use a torsion spring that is installed in the coupling part of the pin and gives elastic force to the pivoting piece.

The guide surface 60 is formed as an inclined surface inclined upward at a certain angle until reaching the horizontal guide surface 13 at one end of the case 10 located in the closing direction of the window.

Due to the formation of the guide surface 60, during the closing operation of the window, the rotational locking piece 40 elastically rotated downward at the maximum angle by the elastic spring moves along the surface of the guide surface 60 and moves along the horizontal guide surface 13 It is guided so that it can be moved to the surface of the

At this time, while moving along the guide surface 60, the rotational angle of the rotational locking piece 40 is gradually reduced, and is moved while being elastically supported on the surface of the horizontal guide surface 13 in a state in which the rotational angle is reduced.

Here, in the present invention, if the guide surface 50 is not formed, the rotational locking piece 40 rotated at the maximum angle cannot be guided to move to the upper surface of the case 10, that is, the horizontal guide surface 13, thereby closing the window. During operation, the end of the case 10 is hit and caught, so that the pivoting piece may be damaged, and the window itself may not be closed.

Therefore, at one end of the case 10, the guide surface 60 must be formed inclined in order to guide the rotational engagement piece 40 to be moved to the horizontal guide surface 13, and the rotation engagement piece 40 is a guide surface ( 60) and the surface of the horizontal guide surface 13 in a sequentially elastically supported state and then engaged with the hook member 23 so that the speed of the window can be gradually reduced by the damping action of the damper 21 will guide

Since the rotational locking piece 40 is elastically supported on the horizontal guide surface 13 of the case 10 by the elastic force, even if the window is raised or moved down relative to the window frame and there is a difference in the interval between them, it is always on the upper surface of the case. remain supported.

Therefore, even if there is a change in the interval between the window and the window frame, the rotational latching piece is elastically supported on the upper surface of the case, so that the rotational latching piece can always be maintained in a hooked state without being disengaged from the hook member. The departure problem does not occur at all.

Accordingly, even if the standard of the window or window frame is different in the system window or the interval between the window and the window frame is changed due to various factors, the system operates reliably without releasing the jammed state.

10 is a view of an embodiment showing the supported state of the pivoting piece when a change occurs in the gap between the window and the window frame while the window moves up or down due to locking and unlocking of the window in the system window, and various external Even if there is a difference in the gap between the window and the window frame due to negative factors, the upper surface of the case, that is, the horizontal guide surface, elastically supports the end of the pivoting latching piece, confirming that the hooking state with the hook member is maintained during the closing operation of the window. .

In the accompanying drawing FIG. 10, (a) shows that the distance between the window and the window frame is 23 mm, and (b) shows that it is 30 mm.

Here, an insertion groove 42 is formed on the lower surface of the other side of the rotational locking piece 40 so that the binding protrusion 27 of the hook member can be inserted in a state in which the window is closed by the hook member 23. .

Among the four side walls forming the insertion groove 42, one side wall located in the direction in which the window opens is formed as a first inclined surface 42a inclined at a predetermined angle.

A locking protrusion 26 protrudes from the upper side of the hook member 23 so as to be caught on the end of the pivoting locking piece 40 during the closing operation of the window, and the upper side of the hook member 23 has a locking protrusion 26 ) is formed with a binding protrusion 27 having a certain length so as to be inserted into the insertion groove 42 in a state where the rotational locking piece 40 is caught.

Here, the locking protrusion 26 not only rotates the hook member at a certain angle while the rotational locking piece 40 is caught during the closing operation of the window, but also draws out the operating rod of the damper 21 to guide the damping operation to be performed is a composition

The binding protrusion 27 is inserted into the insertion groove 42 when the window is closed, and when the window is opened, the binding protrusion 27 is caught on the first inclined surface 42a, which is one side wall of the insertion groove, and bound. In this state, the hook member is moved to retract the operating rod of the damper. The hook member is moved to the curved section of the guide groove 11 by the rotational locking piece and then rotated at a certain angle in the curved section, and at the same time, the rotational locking piece is separated from the hook member as the binding protrusion is separated from the insertion groove.

Here, one side wall of the coupling protrusion 27 facing the first inclined surface 42a is inclined at the same angle as the inclined angle of the first inclined surface 42a or inclined at an angle of less than 10 °. 27a) is formed.

The reason why the first inclined surface and the second inclined surface are formed to be inclined is that the window is opened in a state in which the binding protrusion is bound to the inner wall of the insertion groove in which the first inclined surface is formed during the opening operation of the window. This is to prevent the rotational locking piece from being easily rotated by ensuring that the locking piece is provided in a state accurately caught on the locking protrusion because there is a possibility that the locking protrusion may be separated from the insertion groove while the rotating locking piece is rotated.

In addition, shaking may occur due to various factors during the opening operation of the window, but even in this case, it is to prevent the binding protrusion from being separated from the insertion groove.

On the other hand, in the present invention, a spring fixing part 33 is formed on the lower surface of the fixing plate 30 so that one end of the elastic spring is fixed. A spring insertion groove (33a) is formed to a certain depth so that the elastic spring is inserted.

The spring insertion groove (33a) is rotated while interfering with the contracted elastic spring when the rotation angle of the rotation locking piece 40 gradually decreases as the window moves upward and is folded close to the lower surface of the fixing plate 30. Since there is a possibility that the folding operation of convenience may not be performed smoothly, it is formed to solve this problem.

In the present invention configured as described above, the rotational locking piece is always elastically moved by the elastic spring, so that even if the interval between the window and the window frame is changed due to various factors, the stable and accurate damping operation is performed without the locking state being released or separated. It is a very useful invention to be able to carry out.
