DETAILED DESCRIPTION
A gate unit 10 includes a gate mount 12, a gate 14 mounted on the gate mount 12, and a latch system 16 coupled to the gate 14 as shown in FIG. 1. The gate mount 12 is adapted to mate with a frame 13 bordering a passageway. In the illustrative embodiment, the frame is provided by two substantially parallel surfaces of a door frame and the passageway is the space between the two substantially parallel surfaces. The gate 14 pivots about a gate-pivot axis 18 between an opened position opening a passage 20 formed in the gate mount 12 and a closed position closing the passage 20 formed in the gate mount 12. The latch system 16 is configured to lock the gate 14 in the closed position and unlock the gate 14 so that the gate 14 can be pivoted about the gate-pivot axis 18 to the opened position.
The gate mount 12 includes a horizontal frame 22, a first vertical frame 24, and a second vertical frame 26 in spaced apart relation to the first vertical frame 24 as shown in FIG. 1. The horizontal frame 22 is substantially flush with an underlying floor. The first vertical frame 24 and the second vertical frame 26 extend upwardly from opposing ends of the horizontal frame 22. The first vertical frame 24 is formed to include a latch receiver or catch 28 and an upper bumper insert-receiving passageway 30 at an upper end of the first vertical frame 24.
The horizontal frame 22 extends between and interconnects the first vertical frame 24 and the second vertical frame 26 as shown in FIG. 1. The horizontal frame 22 has a first wall 34 substantially flush with the underlying floor, a second wall 36 in spaced apart parallel-relation to the first wall 34, a third wall 38 extending between and interconnecting the first wall 34 and the second wall 36, and a fourth wall 40 in spaced apart parallel-relation to the third wall 38. In other embodiments, the horizontal frame 22 can have more or less walls to provide the horizontal frame 22 with a different cross sectional shape.
The first wall 34, the second wall 36, the third wall 38, and the fourth wall 40 of the horizontal frame 22 cooperate to form a lower bumper insert-receiving passageway 32 therebetween as shown in FIG. 5. At least one of the third wall 38 and the fourth wall 40 are formed to include a slot 42 extending through the at least one of the third wall 38 and the fourth wall 40. The slot 42 opens into the lower bumper insert-receiving passageway 32 such that a user can visually see into the lower bumper insert-receiving passageway 32.
The gate mount 12 further includes an installation-indicator unit 44 having a lower force indicator 46 and an upper force indicator 48 as shown in FIG. 1. The lower force indicator 46 and the upper force indicator 48 are configured to maintain a stable location of the gate mount 12 within the frame. The lower force indicator 46 and the upper force indicator 48 both cooperate with the frame to securely hold the gate unit 10 within the frame. The installation-indicator unit 44 may further include additional upper and lower installation assemblies coupled to the second vertical frame 26 of the gate mount 12 to further indicate proper installation of the gate 10 within the frame bordering the passageway. In the illustrative embodiment, the upper and lower force indicators 46, 48 may be coupled to an extension 62 also included in the gate mount 12. In some embodiments, the upper and lower force indicators 46, 48 may be coupled directly to at least one of the vertical frames 24, 26 such that the extension(s) 62 is omitted.
The lower force indicator 46 includes a lower indicator panel 50, a lower bumper 52, and a lower bumper insert 54 configured to receive the lower bumper 52 and engage the lower indicator panel 50 as shown in FIG. 5. The lower indicator panel 50 is located within the lower bumper insert-receiving passageway 32 and visible through the slot 42 to the user. The lower bumper 52 directly contacts the frame to locate the gate unit 10 within the frame. The lower bumper insert 54 is received within the lower bumper insert-receiving passageway 32 formed in the horizontal frame 22 of the gate mount 12.
The lower indicator panel 50 displays a first visual representation when a pressure or force less than a first predetermined pressure or force is applied through the lower bumper 52 to the frame bordering the passageway as suggested in FIG. 5. The first visual representation indicates that the gate mount 12 is not properly installed. The lower indicator panel 50 displays a second visual representation when a pressure that is at least the first predetermined pressure is applied through the lower bumper 52 to the frame bordering the passageway to indicate that the gate mount 12 is properly installed. Thus, the lower indicator panel 50 informs the user as to whether the gate mount 12 is properly installed within the frame.
The lower indicator panel 50 is configured to translate within the lower bumper insert-receiving passageway 32 between a first position in which the first visual representation is displayed through the slot 42 and a second position in which the second visual representation is displayed through the slot 42 as suggested in FIG. 5. The lower indicator panel 50 is normally biased outwardly away from a centerline 51 of the gate 14 by a bias member 53 to the first position such that the first visual representation is displayed through the slot 42. In the first position, a pressure less than the first predetermined pressure is applied through the lower bumper 52 to the frame bordering the passageway such that the lower bumper insert 54 does not push the lower indicator panel 50 inwardly toward the centerline 51. The first visual representation suggests that at least a portion of the gate mount 12 is not properly installed within the frame. For example, the first visual representation is displayed when the lower force indicator 46 of the gate mount 12 is not tightly installed within the frame to indicate that the gate mount 12 may be unstable.
The lower bumper 52 includes a screw and a tightening nut that is configured to be tightened between the frame bordering the passageway and the horizontal frame 22 of the gate mount 12 to extend the lower bumper 52 as suggested in FIG. 5. As the tightening nut of the lower bumper 52 is tightened, the lower bumper 52 and/or the lower bumper insert 54 push the lower indicator panel 50 inwardly toward the centerline 51 and toward the second position. The inward movement of the lower indicator panel 50 compresses the bias member 53, which applies pressure or force through the lower bumper 52 to the frame bordering the passageway. Thus, a pressure or force that is at least the first predetermined pressure is applied through the lower bumper 52 to the frame bordering the passageway. In the second position, the lower indicator panel 50 displays the second visual representation through the slot 42. The second visual representation suggests that the gate mount 12 is properly installed within the frame. For example, at least a portion of the gate mount 12 is tightly installed within the frame to indicate that the gate mount 12 is installed. In some embodiments, the first predetermined force is provided only by the bias member 53 and the bias member 53 suspends the gate mount 12 between the lower bumper 52 and a second lower bumper 52 positioned on an opposite side of the gate mount 12.
The upper force indicator 48 of the installation-indicator unit 44 includes an upper indicator panel 56, an upper bumper 58, and an upper bumper insert 60 configured to receive the upper bumper 58 as shown in FIGS. 1 and 6. The upper indicator panel 56 is configured to display a third visual representation when a pressure or force less than a second predetermined pressure or force is applied through the upper bumper 58 to the frame bordering the passageway to indicate that the gate mount 12 is not properly installed. The upper indicator panel 56 is configured to display a fourth visual representation when a pressure or force that is at least the second predetermined pressure or force is applied through the upper bumper 58 to the frame bordering the passageway to indicate that the gate mount 12 is properly installed. The upper bumper 58 directly contacts the frame bordering the passageway but may not directly contact the upper indicator panel 56 or the upper bumper insert 60.
In one embodiment, the first visual representation of the lower indicator panel 50 and the third visual representation of the upper indicator panel 56 includes a first color. In one example, the first color is red. The second visual representation of the lower indicator panel 50 and the fourth visual representation of the upper indicator panel 56 includes a second color different from the first color. In one example, the second color is green. The visual representations may further include other visual indications, such as icons or text, to further indicate the installation state of the gate mount 12. In another embodiment, the first visual representation of the lower indicator panel 50 includes a first pattern and the third visual representation of the upper indicator panel 56 includes the first pattern. The second visual representation of the lower indicator panel 50 includes a second pattern and the fourth visual representation of the upper indicator panel 56 includes the second pattern. The second pattern is different from the first pattern.
In another embodiment, the first visual representation of the lower indicator panel 50 includes a first symbol and the third visual representation of the upper indicator panel 56 includes the first symbol. For example, the first symbol includes an ‘X’. The second visual representation of the lower indicator panel 50 includes a second symbol and the fourth visual representation of the upper indicator panel 56 includes the second symbol. The second symbol is different from the first symbol. For example, the second symbol includes a checkmark.
The indicator panel 50 of the lower force indicator 46 may have a first indication zone 50A, a second indication zone 50B, and/or a third indication zone 50C as shown in FIG. 5. The first indication zone 50A has the first visual representation and is displayed through the slot 42 when the force applied is less than the first predetermined force to indicate more force is needed. The second indication zone 50B has the second visual representation and is displayed through the slot 42 when the force applied is at or greater than the first predetermined force to indicate installation of the lower bumper 52 is complete. The third indication zone 50C has the first visual indication, or a third visual representation different than the first and second visual representations, and is displayed through the slot 42 when the force applied is greater than a second predetermined force higher than the first predetermined force. This can be used to indicate when the lower bumper 52 has been overtightened and at risk of damaging the gate unit 10.
In some embodiments, the gate mount 12 includes a first extension 62 and a second extension 64 as shown in FIG. 1. The first extension 62 and the second extension 64 are coupled to the first vertical frame 24 and the second vertical frame 26, respectively, to allow the gate mount 12 to be installed within a larger frame. The installation-indicator units 46, 48 may be coupled directly to one or both of the extensions 62, 64 and/or the vertical frames 24, 26.
The gate 14 of the gate unit 10 includes a first horizontal member 66, a second horizontal member 68, and a plurality of vertical members 70 extending therebetween as shown in FIG. 1. The first horizontal member 66 is substantially flush with the horizontal frame 22 of the gate mount 12. The second horizontal member 68 is located above the first horizontal member 66. The second horizontal member 68 is coupled with the first vertical frame 24 of the gate mount 12 via the latch system 16 and coupled with the second vertical frame 26 of the gate mount 12 via a hinge. The plurality of vertical members 70 extend between the first horizontal member 66 and the second horizontal member 68 to block the passage 20 formed in the gate mount 12.
The latch system 16 includes an actuator handle 72, a handle lock 74, and a latch 76 as shown in FIGS. 6-11. The actuator handle 72 is coupled with the second horizontal member 68 of the gate 14 and is configured to be maneuvered by a user to unlock the gate 14. The handle lock 74 is coupled with the actuator handle 72 to block movement of the handle lock 74. The actuator handle 72 and the handle lock 74 provide two-stage unlocking of the latch 76 to added child security. The latch 76 is coupled to the actuator handle 72 for movement relative to the gate 14 in response to movement of the actuator handle 72 following disengagement of the handle lock 74. The catch 28 may be included in the latch system 16 in some embodiments.
The actuator handle 72 is configured to move or pivot about a handle-pivot axis 78 as shown in FIGS. 9 and 11. The handle lock 74 includes a handle cover 75 configured to slide relative to the actuator handle 72 to free the actuator handle 72 for movement about the handle-pivot axis 78 as shown in FIG. 8. The handle cover 75 includes at least one actuator cam 73 configured to engage one or more lock pins 71 coupled to the gate 14 to separate the lock pin(s) 71 from the actuator handle 74 and free the actuator handle 72 for movement about the handle pivot axis 78. The latch 76 is configured to move between a locked configuration in which the latch 76 engages or extends into the latch receiver or catch 28 formed in the first vertical frame 24 of the gate mount 12 to lock the gate 14 in the closed position so that the gate 14 is blocked from movement about the gate-pivot axis 18, as shown in FIG. 7, and an unlocked configuration in which the latch 76 disengages or is removed from of the latch receiver 28 formed in the first vertical frame 24 of the gate mount 12 to unlock the gate 14 so that the gate 14 is free to move to the opened position about the gate-pivot axis 18, as shown in FIG. 9.
The latch 76 includes a latch pin 77 and a latch-pin mover 79 as shown in FIGS. 10-12. The latch pin 77 is configured to engage with the latch receiver 28 to block movement of the gate 14 about the gate pivot axis 18. The latch-pin mover 79 is coupled with the latch pin 77, the actuator handle 72, and the gate 14. The latch-pin mover 79 is configured to move the latch pin 77 away from the latch receiver 28 upon actuation of the latch handle about the handle pivot axis 78 to unlock the gate 14 for movement about the gate pivot axis 18.
The latch-pin mover 79 includes a bias member 80, a washer 81, and a plurality of linkages 82 as shown in FIGS. 10-12. The bias member 80 is coupled between the latch pin 77 and the plurality of linkages 82 and is configured to urge the latch pin 77 toward the latch receiver 28. The washer 81 is coupled between the bias member 80 and the plurality of linkages 82. The plurality of linkages 82 are configured to move the latch pin 77 relative to the gate 14 between the locked configuration and the unlocked configuration.
The plurality of linkages 82 includes a first linkage 84 coupled to the latch 76, a second linkage 86 coupled to the actuator handle 72, and a third linkage 88 coupled to the first horizontal member 66 of the gate 14 as shown in FIGS. 10-12. The first linkage 84 has a first end 90 coupled to the latch pin 77 and a second end 92 coupled with the second linkage 86 and the third linkage 88. The second linkage 86 has a first end 94 coupled to the second end 92 of first linkage 84 and a second end 96 coupled to the actuator handle 72. The third linkage 88 has a first end 98 coupled to the first end 94 of the second linkage 96 and second end 100 coupled to the gate 14. Each end of the linkages 82 is mounted for pivotable movement relative to one another and relative to the gate 14.
The second linkage 86 is configured to move with the actuator handle 72 about the handle pivot axis 78 to decrease a distance between the first end 90 of the first linkage 84 and the second end 100 of the third linkage 88. In response to this movement, the first linkage 84 is configured to withdraw the latch pin 77 from the latch receiver 28 formed in the gate mount 12 in the unlocked configuration.
The latch pin includes a pin base 102 configured to engage with the latch receiver 28 and a guide post 104 coupled to the pin base 102 and to the first end 90 of the first linkage 84. The pin-bias member 80 includes a spring wrapped around the guide post 104 and configured to apply a force between the first end 90 of the first linkage 84 and the pin base 102 to urge the latch pin 77 toward the latch receiver 28.
The guide post 104 is formed to include a slot 106 that receives a portion of the first end 90 of the first linkage 84 as shown in FIGS. 10 and 11. The latch pin 77 is configured to translate relative to the gate 14 and the plurality of linkages 82 between an extended position and a retracted position to indicate when installation of the gate unit in the frame 13 is complete. In the extended position, the latch base 102 is separated from the latch receiver 28 and is spaced a first distance from the first end 90 of the first linkage 84 prior to installation of the gate unit 10 in the frame 13. In the retracted position, the latch base 102 engages the latch receiver 28 and is spaced a second distance from the first end 90 of the first linkage 84, less than the first distance, after installation of the gate unit 10 in the frame 13. The spring of the pin-bias member 80 has a first length when the latch pin 77 is in the extended position and a second length, less than the first length, when the latch pin 77 is in the retracted position.
To unlock and open the gate 14, the actuator handle 72 is pivoted in a first (i.e. counterclockwise) direction about the handle-pivot axis 78 and the handle lock 74 is moved away from the latch receiver 28 and toward the centerline 51 as shown in FIGS. 1 and 4. The second linkage 86 translates the pivoting movement of the actuator handle 72 about the handle-pivot axis 78 to the first linkage 84, and the first linkage 84 pulls the latch 76 inwardly and out of the latch receiver 28 formed in the gate mount 12 so that the latch 76 is in the unlocked configuration.
To lock and close the gate 14, the handle lock 74 is moved toward the latch receiver 28 and away from the centerline 51, and the actuator handle 72 is pivoted in a second (i.e. clockwise) direction toward the second horizontal member 68 of the gate 14 as shown in FIGS. 6-9. The second linkage 86 translates the pivoting movement of the actuator handle 72 about the handle-pivot axis 78 to the first linkage 84. The first linkage 84 extends the latch 76 into the latch receiver 28 formed in the gate mount 12 so that the latch 76 is in the locked configuration. The movement of the first linkage 84 compresses the bias member 80 between the latch 76 and the washer 81 so that pressure is applied through the second horizontal member 68 of the gate 14 to the first vertical frame 24 of the gate mount 12, and thus, the upper bumper 58 and the frame bordering the passageway. The actuator handle 72 may be biased in the second direction and the handle lock 74 may be biased to a locked position blocking movement of the actuator handle in the first direction.
In one embodiment, the upper indicator panel 56 of the upper force indicator 48 is formed on the latch system 16. For example, the upper indicator panel 56 of the upper force indicator 48 may be formed on the latch 76. In another embodiment, the upper indicator panel 56 of the upper force indicator 48 is formed on the gate 14, such as on the second horizontal member 68. In another embodiment, the upper indicator panel 56 of the upper force indicator 48 is formed on the gate mount 12, such as on the first vertical frame 24.
The upper indicator panel 56 of the upper force indicator 48 is configured to display the third visual representation when the latch 76 is retracted from the latch receiver 28 formed in the gate mount 12 to indicate that the gate 14 is in the opened position and the latch 76 is in the unlocked configuration as shown in FIGS. 4 and 5. The upper indicator panel 56 is configured to display the fourth visual representation when the latch 76 extends into the latch receiver 28 formed in the gate mount 12 to indicate that the gate 14 is in the closed position and the latch 76 is in the locked configuration, as shown in FIGS. 7 and 8. Thus, the user can verify when the gate 14 is in the closed position and the latch 76 is in the locked configuration. The fourth visual representation is also displayed when the gate mount 12 is properly installed such that the upper indicator panel 56 provides multiple indications for users with the fourth visual indication.
The second visual representation of the lower indicator panel 50 is visible to the user via the slot 42 when the latch 76 is in the locked configuration and the gate 14 is in the closed position as shown in FIG. 1. The fourth visual representation of the upper indicator panel 56 is visible to the user when the latch 76 is in the locked configuration and the gate 14 is in the closed position as shown in FIG. 1. The upper force indicator 48 may further include a fifth visual representation 57 coupled to the gate 14 and blocked by the handle 72 in the locked configuration and exposed when the handle 72 is in the unlocked configuration.
The indicator panel 56 of the upper force indicator 48 may have a first indication zone 56A, a second indication zone 56B, and/or a third indication zone 56C as shown in FIG. 12. The first indication zone 56A has the third visual representation and is displayed when the force applied is less than a predetermined force to indicate more force is needed. The second indication zone 56B has the fourth visual representation and is displayed when the force applied is at or greater than the predetermined force to indicate installation of the upper bumper 58 is complete. The third indication zone 56C has the third visual representation, or another visual representation different than the third and fourth visual representations, and is displayed when the force applied is greater than a second predetermined force higher than the predetermined force. This can be used to indicate when the upper bumper 58 has been overtightened and at risk of damaging the gate unit 10.
Each of the bias members 53, 80 is designed to exert predetermined forces for use with the installation-indicator unit 44 to indicate when installation of the gate unit 10 in the frame 13 is complete. In the illustrative embodiment, each bias member 53, 80 has a spring constant which provides each respective predetermined force. In the illustrative embodiment, the predetermined force of both force indicator units 46, 48 is at least 80 lbf. In some embodiments, the predetermined force of both force indicator units 46, 48 is within a range of about 50 lbf to about 120 lbf. In some embodiments, the predetermined force of both force indicator units 46, 48 is within a range of about 60 lbf to about 100 lbf. In some embodiments, the predetermined force of both force indicator units 46, 48 is within a range of about 70 lbf to about 90 lbf.
In the illustrative embodiment, the bias member 53 of the lower force-indicator unit 46 has a first spring constant and the bias member 80 of the upper force indicator unit 48 has a second spring constant greater than the first spring constant. In this regard, the bias member 80 of the upper force indicator unit 48 may have a greater spring constant compared to the bias member 53 in the lower force indicator 46 so that the bias member 80 has less displacement (or compression) during installation compared to the bias member 53. Less displacement of the bias member 80 in the upper force indicator 48 may be desired when, as in the present disclosure, the indicator panel 56 is integrated into the latch pin 77.
