Description

Glass bonding clamp}

The present invention relates to a clamp for bonding glass, and more particularly, to a clamp for bonding glass capable of maintaining a pressed state with respect to laminated glass.

A glass plate bonded between the glass plates using an adhesive member is referred to as laminated glass. That is, while the single glass plate scatters fragments when broken, even if the laminated glass is broken, the fragments are not scattered by the adhesive member and the shape is maintained, thereby ensuring safety.

In order to manufacture such a laminated glass, a structure in which an adhesive member (eg, a PVB bonding film, etc.) is attached between glass plates (eg, a tempered glass plate or a general glass plate, etc.) is heated in a preload furnace for primary bonding treatment After (hereinafter, the treated structure is referred to as “primary laminated glass”), the primary laminated glass may be placed in an autoclave and subjected to high temperature and high pressure treatment. In particular, the productivity and quality of the laminated glass can be further improved by holding the primary laminated glass pressed against the primary laminated glass using a clamp before putting it into the autoclave.

On the other hand, the conventional clamp for glass bonding has a structure in which the bolt must be directly tightened so that the bolt contacts the primary laminated glass in order to press the primary laminated glass. As a result, the conventional clamp for glass bonding is not only inconvenient to press and release, but also has a problem in that the primary laminated glass can be easily damaged due to a small pressing area.

In addition, the conventional clamp for glass bonding is difficult to utilize space due to a too large separation distance, and a protruding part (for example, bolt, nut, handle, etc.) is formed on the upper or lower surface corresponding to the outer surface. Due to this, it has a structure in which it is difficult to laminate a plurality of primary laminated glasses. As a result, the conventional clap for glass bonding has a problem in that the number of primary laminated glass that can be accommodated in the autoclave is small, and the production amount of laminated glass is inevitably small.

The clamp 1000 according to an embodiment of the present invention may be used as a clamp for glass bonding. In particular, the clamp 1000 according to an embodiment of the present invention may be used as a clamp for maintaining the primary laminated glass in a pressed state before putting the primary laminated glass into an autoclave. At this time, the primary laminated glass may be a structure in which an adhesive member A is attached between the glass plates G1 and G2, as shown in FIGS. 6 and 7, and after the structure is heated in a preload furnace state may be For example, the glass plates G1 and G2 may be at least one of a tempered glass plate and a general glass plate, and the adhesive member A may be a PVB bonding film having adhesive strength, but is not limited thereto.

1 to 7, the clamp 1000 according to an embodiment of the present invention has the outer surfaces 101 and 201 and the inner surfaces 102 and 202 of one side in contact with the primary laminated glass. Each of the two supports 100 and 200 having a flat surface, and the first protrusions 103 and 203 of the respective supports 100 and 200 are inserted into the first holes 104 and 204 of the supports 100 and 200 respectively. The connecting bar 300 connecting , The moving part 500 that is threadedly coupled to the screw shaft 401 of the rotating part 400 having a screw thread, and the connecting bar 300 pass through and the end of the screw shaft 401 is inserted, the connecting bar 300 and the screw By connecting the shaft 401 , a connector 600 supporting the screw shaft 401 may be included, respectively.

Each support (100, 200) has a plate-shaped body, and the first protrusion (103, 203) protruding toward each other between one side and the other side of the body, that is, protruding toward the inner surface (102, 202) be prepared For example, the first support 100 may have two protrusions 103 spaced apart from each other, and the second support 200 may have two first protrusions 203 spaced apart from each other, and each protrusion (103, 203) may be formed in a shape bent toward the inner surface (102, 202) from both sides of the body portion of each support (100, 200), but is not limited thereto.

In addition, each of the supports 100 and 200 has second protrusions 105 and 205 protruding from the other side toward each other, that is, protruding toward the inner surfaces 102 and 202 thereof. For example, each of the second protrusions 105, 205 may be formed in a shape bent from the other side of the body of each support 100, 200 toward the inner surfaces 102 and 202, but is not limited thereto. .

First holes 104 and 204 may be formed in each of the first protrusions 103 and 203 . At this time, the connecting bar 300 having a circular cross section is inserted into the first holes 104 and 204 , and the inserted connecting bar 300 may act as a central axis for rotation of each of the supports 100 and 200 . . That is, the inner peripheral surface of each of the first holes 104 and 204 and the outer peripheral surface of the connecting bar 300 are not fixedly joined, and the outer peripheral surface of the connecting bar 300 is guided by the inner peripheral surface of the first holes 104 and 204 and rotates. can do. As a result, each of the supports 100 and 200 may rotate according to each of the first holes 104 and 204 connected thereto around the connecting bar 300 .

Second holes 106 and 206 may be formed in each of the second protrusions 105 and 205 . In this case, each of the second holes 106 and 206 may have a shape extending in a vertical direction, and may have a shape extending to the other side portion (including a bent portion) of each support member 100 , 200 . The screw shaft 401 of the rotating part 400 is inserted into the second holes 106 and 206 of this shape. Accordingly, the inserted screw shaft 401 connects the other side of each supporter 100 and 200 that can move up and down when rotating the connecting bar 300 as a central axis, but up and down between the other sides of each supporter 100 and 200 When the movement becomes more than a certain level, the vertical movement may be restricted so as to act as a jamming action. That is, each of the second protrusions 105 and 205 about the inserted screw shaft 401 may overlap each other.

In addition, when moving up and down between the other sides of each support 100 , 200 , each of the second protrusions 105 , 205 overlaps each other and any one of the second protrusions 105 , 205 is inserted into the second hole of the other. it might be This configuration can increase the rotation radius of each support (100, 200) that rotates about the connecting bar (300) as a central axis.

Each of the supports 100 and 200 may have an inner surface 102 and 202 of one side formed to be flat, and a primary laminated glass may be disposed between the inner surfaces 102 and 202 . That is, the inner surfaces 102 and 202 of each side act as a pressing portion for the primary laminated glass, and surface contact with the primary laminated glass is possible. As a result, the present invention has the advantage of reducing the possibility of damage to the primary laminated glass because the pressing area for the primary laminated glass is large.

However, it may be preferable that the inner surfaces 102 and 202 of the respective supports 100 and 200 are bent in the inward direction. That is, the inner surfaces 102 and 202 of each of the supports 100 and 200 may be bent in a direction in which one side and the other side approach each other, or in a direction in which the other side of each inner surface 102 and 202 approaches each other. This bending configuration can more effectively strengthen the control action of the moving unit 500 with respect to the separation distance d1 between one side of each of the supports 100 and 200 . A more detailed description thereof will be provided later.

The connecting bar 300 inserted into each of the first holes 104 and 204 of each of the supports 100 and 200 may have engaging portions 700 at both ends thereof. The locking part 700 acts as a hook so that the connecting bar 300 does not separate from each of the first holes 104 and 204 . That is, the engaging portion 700 may have a larger diameter than the connecting bar 300 or each of the first holes 104 and 204 . For example, the locking part 700 is a clip or pin inserted and fastened into the first grooves 301 and 302 formed at both ends of the connecting bar 300 , or screw thread coupling to the threads formed at both ends of the connecting bar 300 . It may be a nut or the like, but is not limited thereto.

The rotating unit 400 includes a head 402 and a screw shaft 401 , respectively. A screw thread is formed on the surface of the screw shaft 401 , and a third hole 404 is formed in the head 402 , and the handle 800 may be inserted into the third hole 404 . The head 402 may be formed to have a larger diameter than the screw shaft 401 and may be formed in various shapes to engage the second holes 106 and 206 . That is, the head 402 catches the second hole of the second protrusion located more outside of the two overlapping second protrusions 105 and 205 (eg, a diameter larger than a specific diameter size of the second hole) to have) can be formed.

The moving part 500 is threadedly coupled to the screw shaft 401 . That is, the moving part 500 includes a screw hole 501 through which the screw shaft 401 passes. The screw hole 501 has a through hole formed along the longitudinal direction of the screw shaft 401, and the through surface A thread corresponding to the screw shaft 401 is formed on the screw shaft 401 and the screw thread is coupled. Accordingly, referring to FIGS. 4 and 5 , when the rotating unit 400 rotates in one direction or the other direction, the moving unit 500 is threadedly coupled to the screw shaft 401 according to the length of the screw shaft 401 . Move to one side or the other side of the direction. As the moving unit 500 moves, the portion of the moving unit 500 in contact with the moving unit 500 and the inner surfaces 102 and 202 of the respective supports 100 and 200 is also changed, and each support 100 , 200) may be spaced apart from each other. As a result, each support ( 100 , 200 ) is axially rotated about the connecting bar ( 300 ), and the separation distance ( d1 ) between one side of each support ( 100 , 200 ) may also be adjusted.

That is, when the rotating unit 400 rotates in one direction, the moving unit 500 moves to the other side (head 402 direction) in the longitudinal direction of the screw shaft 401 according to the screw thread coupling with the screw shaft 401 . . Accordingly, the moving unit 500 moves closer to the other side of the inner surfaces 102 and 202 of the respective supports 100 and 200 while in contact with the inner surfaces 102 and 202 of each of the supports 100 and 200 . As a result, as the separation distance between the other sides of each support 100, 200 increases, the support force of the other side is strengthened, and as each support 100, 200 is axially rotated around the connecting bar 300, each support 100 , 200), the distance d1 between one side becomes narrower, but the intellectual power of the one side can be strengthened. This corresponds to the action of pressing the primary laminated glass inserted between one side of each support (100, 200). That is, each of the inner surfaces 102 and 202 may press the primary laminated glass while in closer contact with the primary laminated glass located between the inner surfaces 102 and 202 of one side of each support 100 and 200 .

In addition, when the rotating part 400 rotates in the other direction, the moving part 500 is one side in the longitudinal direction of the screw shaft 401 (end direction of the screw shaft 401) according to the screw thread coupling with the screw shaft 401 . move to Accordingly, the moving unit 500 gradually moves closer to one side of the inner surfaces 102 and 202 of the respective supports 100 and 200 while in contact with the inner surfaces 102 and 202 of the respective supports 100 and 200 . As a result, the separation distance between the other sides of each support 100, 200 is narrowed or the support force of the other side is weakened, and as each support 100, 200 is axially rotated around the connecting bar 300, each support 100 , 200), the separation distance d1 between one side may increase or the bearing force of the one side may be weakened. This corresponds to an action of releasing the pressure on the primary laminated glass pressed between one side of each of the supports 100 and 200 .

In addition, as shown in FIGS. 4 and 5 , each support 100 , 200 is provided on both sides of the body part so that the control action of the moving part 500 can be more effectively strengthened even under a small amount of movement of the moving part 500 . has a shape bent toward its inner surface 102, 202, and the moving unit 500 corresponds to the inclination according to the bending of the inner surface 102, 202 of each support 100, 200. 502). That is, the inner surfaces 102 and 202 of each support 100 and 200 have an inclination to be closer to each other from the bent portion to the other side according to the bending, and the moving unit 500 has these inner surfaces 102 and 202 It has an inclined surface 502 having a shape corresponding to the corresponding inclination so that it can move between one side and the other side while corresponding to the inclination of the liver. Accordingly, when the pressing action on the primary laminated glass, the supporting force for the pressing can be further strengthened, and when the releasing action on the primary laminated glass is performed, the supporting force can be more easily weakened.

On the other hand, since each of the supports 100 and 200 has a structure in which the first protrusions 103 and 203 protruding toward each other overlap each other and are connected by the connecting bar 300, the distance between each other can be short. . At the same time, when the primary laminated glass is employed, each of the supports 100 and 200 has a length L1 between the portions where each of the first protrusions 103 and 203 are formed among the lengths between the inner surfaces 102 and 202 thereof. That is, the length between the first protrusion 103 on one side of the first support 100 fastened to the connecting bar 300 and the first protrusion 203 on one side of the second support 200 fastened to the connecting bar 300 . It may be configured such that the configuration protruding from the height of (L1) is minimized. In order to minimize the protrusion configuration, the protrusion lengths L2 and L2 of the second protrusions 105 and 205 bent from the other side of each support 100 and 200 toward the inner surface thereof may be smaller than L1.

In particular, during the pressure release action of the moving part 500 , the other side of each supporter 100 , 200 , which is rotatable around the connection bar 300 , is able to move up and down by a predetermined amount as the support force is weak and loose. At this time, if the other side of each of the supports 100 and 200 moves too close to each other, the second protrusions 105 and 205 may protrude from the relative supports 100 and 200 at the height of L1 or more. In order to prevent this, the movable unit 500 is configured such that the second protrusion 105, 205 does not protrude more than a certain level from the height of L1 because the other side of each support 100, 200 does not come closer than a certain level during the pressure release action. It can act to limit the movement of (100, 200). That is, the movable unit 500 may act as a latching action for each of the supports 100 and 200 when the respective supports 100 and 200, which are movable so that the other sides thereof move closer to each other during the pressure release action, move more than a certain amount.

Accordingly, as shown in FIG. 7 , the plurality of structures in which the plurality of burn clamps 1000 are employed on the side surface of the primary laminated glass can be stacked while minimizing waste space by minimizing the protrusion configuration, so that as many as possible in the same space can be stacked. In this case, the stacking may include both a case in which the flat surface of each structure is overlapped to face the floor, and a case in which the flat surface is erected perpendicular to the floor and overlapped.

That is, as each clamp 1000 in contact with each other has a structure that minimizes the configuration protruding onto the outer surfaces 101 and 201, each structure is stacked while easily minimizing wasted space without interfering with a plurality of structures. can do it In particular, when any one of each of the second protrusions 105 is configured to be insertable into the second hole of the other, the above-described movement limiting action of the moving unit 500 for each support 100 , 200 is also performed. As a result, the present invention can increase the number of primary laminated glasses that can be accommodated in the autoclave, thereby increasing the production of laminated glass.

The connecting body 600 includes a fourth hole 601 that is a through hole through which the connecting bar 300 passes, and a second groove 601 into which the end 403 of the screw shaft 401 is inserted. Of course, the second groove 501 may be formed in the shape of a through hole. As the connecting bar 300 passes through the fourth hole 601 and the end 403 of the screw shaft 401 is inserted into the second groove 501 , the connecting body 600 is connected to the connecting bar 300 . and the rotating part 400 can be connected, and as a result, the screw shaft 401 can be supported. This is a screw based on the connecting bar 300 that can provide stable support force with less shaking as it is inserted into the first holes 104 and 204 of the first protrusions 103 and 203 through the connecting body 600 . This is because the shaft 401 can be connected.

On the other hand, referring to FIGS. 4 and 5 , the end 403 of the screw shaft 400 inserted into the second groove 602 of the connector 600 has a locking part that engages the second groove 602 . may include For example, the locking part is in the form of a locking jaw formed in the end 403 of the screw shaft 400 to have a larger diameter than the diameter of the second groove 602 , or a groove formed in the end 403 of the screw shaft 400 . It may be a clip or pin to be inserted and fastened to, or a nut for screw thread coupling to a thread formed on the end 403 of the screw shaft 400, but is not limited thereto. However, in the case of the locking jaw shape, it may be formed through a rivet process. That is, after inserting the end 403 of the screw shaft 400 having the same or smaller diameter as the second groove 602 into one side of the second groove 602 that is a through hole, the other side of the corresponding through hole of the connector 600 . By applying an impact to the end 403 in the second groove 602 can be formed with a larger diameter than the stopping protrusion.

For a smoother control action of the moving unit 500 , the handle 800 may be connected to the head 402 of the rotating unit 400 . That is, the handle bar 801 may be inserted through the third hole 404 of the head 402 , and handle locking portions 802 and 803 may be employed at both ends of the handle bar 801 . At this time, the handle locking parts 802 and 803 act as a hook so that the handle bar 801 does not deviate from the third hole 404 . That is, the handle engaging portions 802 and 803 may have a larger diameter than the handle bar 801 or the third hole 404 . For example, the handle locking parts 802 and 803 may be inserted and fastened into grooves formed at both ends of the handle bar 801 or a pin, or a nut that is threadedly coupled to the threads formed at both ends of the handle bar 801. , but is not limited thereto. The handle bar 801 is freely movable in the longitudinal direction in the third hole 404 until the handle engaging portions 802 and 803 are caught in the third hole 404, and accordingly, the user can use the handle 800 It is possible to more easily perform a rotational action on the rotating part 400 and a control action of the moving part 500 by the corresponding rotational action by using the .

In particular, the rotating part 400 is formed in the same shape as a screw bolt, and the head 402 protrudes from the side of each support 100, 200, and the handle 800 is connected to the protruding head 402. Accordingly, in the present invention, it is possible to more easily adjust the rotation of the rotating unit 400 . If the head 402 is formed to be hidden between the inner surfaces 102 and 202 of each of the supports 100 and 200, the shape of the handle 800 becomes complicated or even the handle 800 rotates with respect to the rotating part 400 Control can be uncomfortable.

However, in FIGS. 6 and 7 , the moving part 500 is positioned close to one side while pressing the primary laminated glass for convenience, but the present invention is not limited thereto, and the moving part 500 depends on the thickness of the primary laminated glass. The position at which 500 presses the primary laminated glass may be further changed in one or the other direction. That is, when it is thinner than the primary laminated glass shown in FIGS. 6 and 7 , the moving unit 500 may press the primary laminated glass at the position of the other side.

Meanwhile, an elastic part (not shown) may be provided between the respective supports 100 and 200 . For example, the elastic part is disposed to be in contact with the inner surfaces 102 and 202 of each of the supports 100 and 200 while facing in one direction of the respective supports 100 and 200 while being disposed to be inserted into the connecting bar 300. can In this case, the elastic force in the direction of reducing the separation distance between the other sides of each support ( 100 , 200 ), that is, the elastic force in the direction of increasing the separation distance between one side of each support ( 100 , 200 ) acts on the elastic part.

Or, conversely, the elastic part is inserted into the connecting bar 300 while disposed so that both ends thereof are in contact with the inner surfaces 102 and 202 of the respective supports 100 and 200 while facing the other direction of the respective supports 100 and 200. can In this case, the elastic force in the direction of reducing the separation distance between the one side of each support ( 100 , 200 ), that is, the elastic force in the direction of increasing the separation distance between the other sides of each support ( 100 , 200 ) acts on the elastic part.

By supporting such an elastic part so as not to loosen one side or the other side of each support 100, 200, it is possible to further support and strengthen the control action of the moving part.

The present invention configured as described above adjusts the distance between the other sides of each support 100, 200 by adjusting the position of the moving part 300 according to the rotation adjustment of the rotating part 400, so that each support 100, 200 ) by rotating the shaft around the connecting bar 300 , it is possible to adjust the separation distance d1 between one side of each support 100 , 200 , and there is an advantage in that it is easy to press and release the primary laminated glass.

In addition, since the present invention is configured so that the inner surfaces 102 and 202 of the respective supports 100 and 200 are in surface contact with the primary laminated glass, the pressure area for the primary laminated glass is large, and the damage to the primary laminated glass is large. There are advantages to reducing the likelihood.

In addition, in the present invention, the separation distance between each support 100, 200 can be short, and it does not have a configuration that protrudes from the outer surfaces 101 and 201 of each support 100, 200, so the stacking of a plurality of structures Since the waste space can be minimized, there is an advantage in that the production of laminated glass can be increased by increasing the number of primary laminated glass that can be accommodated in the autoclave.
