Description

Door mirror safety cover

The present invention relates to a safety cover for a door viewing mirror device such as a peephole.

A door sighting device, such as a peephole, acts as a safety device that allows an observer located on one side of the door, such as a door, to view a visitor located on the other side of the door, such as a door. Such door sighting devices typically include a lens system that produces a virtual image of various objects located in front of the door. During operation, the user behind the door views the area near the door through the door mirror device, thereby enabling the user to confirm the identity of the person or the characteristics of the object before opening the door. Traditional door mirror devices have some drawbacks. First, the conventional door mirror device allows for double-sided viewing. That is to say, when the door mirror device allows the inside observer to see the area in front of the door, the door viewing mirror also allows the observer in front of the door to see the area near the back side of the door. In addition, the conventional door mirror device allows an external observer, that is, a person in front of the door, to observe changes in light produced by the inner observer as they approach the door and see through the peephole. When the light in the peephole changes, for example, from light to dark, the observer observes that someone is located behind the door inside the house, apartment, company, etc. within the structure. This affects the safety of people located within the structure.

Therefore, it is desirable to provide a safety device that prevents external observers from seeing See security areas such as houses, offices, etc., and enable internal observers to see through the door mirror without creating light changes during viewing.

This creation is directed to a security cover for a door viewing mirror such as a peephole. The safety cover includes a housing including a front aperture, a rear aperture aligned with the front aperture, and a shutter mechanism disposed between the two apertures. By operating the actuator, the shutter mechanism is reset from the closed position in the open position. In operation, the safety cover is coupled to the door such that the safety cover surrounds the peephole and the front aperture is aligned with the viewing port of the peephole. The safety cover can also include an eye cup that is secured to the back panel.

In this document, the same elements are labeled with the same reference numerals.

1A and 1B illustrate a security cover for a door viewing mirror in one embodiment of the present creation. As shown, the security cover 10 includes a body or housing 100 having a generally cylindrical side wall 105, A front panel 110 including a front aperture 115, and a rear panel 120 including a rear aperture 125 (or viewing aperture). An eye cup 130 (like an eye cup or eyecup found by a telescope) is attached to the rear panel 120 that surrounds the viewing aperture. As shown, the front panel 110 is disposed within the body 100; the front panel is axially spaced from the front end of the body. The front panel has a forwardly facing and generally annular outer edge 135 that is operatively in contact with the door surface. The outer rim 135 can be configured to connect to the door surface. For example, the outer edge 135 can be coated with an adhesive. In other embodiments, the safety cover 10 can include one or more fastening components, such as a grommets, that extend radially from the body 100 to allow fasteners such as nails or screws to secure the security cover 10 to the door. In operation, the safety cover 10 is attached to the rear surface of the door such that the outer edge 135 encloses the viewing port of the door viewer and the front aperture is generally aligned with the viewing port. After being connected to the door, the inner observer, i.e., the person located on the back side of the door or in the door, approaches the eye cup 130, sees through the rear aperture 125 and the front aperture 115, and looks through the door viewing mirror.

The safety cover 10 also includes a shutter mechanism disposed between the two apertures of the front aperture 115 and the rear aperture 125 for operatively selectively opening and closing the rear aperture 125. Referring to Figure 2, the rear side 205 of the front panel 110 includes a first post 210A that is laterally separated from a second post 210B. Each of the first column 210A and the second column 210B extends axially from the rear side or the front plate 110. The first shutter member 220A is pivotally mounted on the first post 210A, and the second shutter member 220B is pivotally mounted on the second post 210B. The first shutter member 220A and the second shutter member 220B may be biased toward the center of the hole, that is, mutually offset, by a biasing member 225 such as a spring that spans the member.

The first shutter member 220A includes a body 230A that is substantially semi-circular, has a straight side portion 235A, and a rounded portion 240A. The body 230A also includes a truncated region 245 along its proximal portion that is configured to frictionally match the protruding region of the second shutter 220A. The second shutter member 220B includes a body 230B that is substantially semi-circular and has a substantially straight portion 235B and a substantially rounded portion 240B. The first shutter member 220A and the rounded portion 240A, 240B of the second shutter member 220B The radius of curvature corresponds to the radius of curvature of the inner surface 247 of the side wall. With this configuration, the rounded portions 240A, 240B form a contour with respect to the sidewall area. Additionally, the inner surface 247 of the body 100 includes a recess 248 that defines an annular shoulder; on the annular shoulder, a rear plate 120 is disposed.

The second shutter member 220B also includes a stem 250 that extends radially from the body 230B. Rod The base 252 of 250 is configured to engage the truncated region 245 of the first shutter body 230A such that rotation of the second shutter member 220B causes the first shutter member 220A to rotate in the opposite direction. This will be explained in more detail below. The distal end portion of the stem 250 of the second shutter member 220B extends through a long slot 255 formed in the side wall 105 of the housing 100. The slot 255 can define the length of movement of the lever 250 that the user can move during operation.

The operation of the safety cover 10 will be explained with reference to Figs. 3A and 3B. Biasing member 225 is normal Or the closed position biases the first shutter member 220A and the second shutter member 220B, wherein the straight side portions 235A, 235B of the first shutter member 220A and the second shutter member 220B are in contact with each other. In this position, the bodies 230A, 230B of each of the first shutter member 220A and the second shutter member 220B at least partially block the front aperture 115. Therefore, an observer located inside the door cannot be viewed through the security cover 10. Similarly, an observer located outside the door cannot see the change in light through the door mirror or the area near the inner door surface. If the inner observer wants to see the door mirror, the inner observer needs to pivot the lever 250 (shown by arrow F) to rotate (eg, clockwise in the angle of FIG. 3B) the upper circle of the second shutter member 220B, ie The base 252 is to the upper circle of the first shutter member 220A, that is, the truncated portion 245. Rotation of the second shutter member 220B causes the base 252 of the lever 250 to frictionally engage the truncated portion 245 of the first shutter member 220A; therefore, clockwise rotation of the second shutter member 220B causes the first shutter member 220A to rotate counterclockwise. Therefore, the first shutter member 220A and the second shutter member 220B are separated and moved from the normally closed position (Fig. 3A) to the open position (Fig. 3B). Since the rounded portions 240A, 240B of the first shutter member 220A and the second shutter member 220B form the inner surface 247 of the side wall 105 The contour is such that the shutter member abuts the side wall. With this configuration, in the open position, the main shutter member 220A, the main body 230A, 230B of the second shutter member 220B are removed from the front hole 115 and the rear hole 125, allowing the inner observer to see through the safety cover 10 and the door mirror device.

Therefore, this creation provides an inexpensive, easy to operate device that can be connected Receive any traditional door that includes a door mirror. The safety cover 10 is biased in its closed position; therefore the external observer, ie the observer in front of the door, cannot see protected structures such as houses, apartments, etc. through the door viewing mirror. In addition, the external observer does not see any changes in the light produced by the observer as they approach the door. If the inner observer wants to see the door-viewing mirror device, the inner observer only needs to bring the eye closer to the eye cup 130, further preventing light from entering the door viewing mirror device, and then using the lever 250 to open the above-described shutter mechanism. The internal observer can now view the external observer to confirm the identity of the external observer. During the viewing process, because there is no light change, the external observer still does not know the existence of the internal observer.

Figure 4 shows a safety cover for a door viewer device in another aspect of the present invention 40. As shown, the security cover 40 includes a structure similar to that described above that includes a housing 400 having a side wall 405, and axially extending posts 407A, 407B disposed on the rear side 410 of the front panel 415. This configuration also includes a first shutter member 420A having a first rod 425A and a first body 430A and a second shutter member 420B having a second rod 425B and a second body 430B. That is, each of the first shutter member 420A and the second shutter member 420B now includes a first rod 425A and a second rod 425B extending radially from the first body 430A and the second body 430B instead of using two valves including control. The single-bar mechanism of the part. Further, the shutter first body 430A and the second body 430B may no longer be meshed together. The housing 400 further includes a first groove 435A corresponding to the first rod 425A and a second groove 435B corresponding to the second rod 425B.

In operation, as shown in Figure 5A, the shutter mechanism is in its normal closed position. The inner observer drives the first rod 425A and the second rod 425B close to each other, for example, as shown by the arrows F1 and F2, the operator presses the rods together. Each of the first shutter member 420A and the second shutter member 420B pivots along its corresponding post 407A, 407B to rotate the first shutter member 420A in one direction, for example, as indicated by an arrow R2, in a counterclockwise direction The second shutter member 420B is rotated in the opposite direction, for example, in a clockwise direction as indicated by an arrow R1. The first shutter member 420A and the second shutter member 420B are rotated until the first body 430A and the second body 430B are removed from the front hole 450 and the rear hole 460. After being removed from the front hole 450, the inner observer can see through the safety cover 10 and the door mirror device to view the area in front of the door. When the levers 405A, 405B are released, the biasing member 455 drives the first shutter member 420A and the second shutter member 420B back to their normal (closed) positions, wherein each of the first body 430A and the second body 430B at least partially blocks the front hole 450.

Figure 6 shows a security cover for a door viewer device in another aspect of the present invention. As shown, the security cover 60 includes a housing 600 having a side wall 605; the side wall 605 includes a front panel 610 having a front aperture 615, a rear panel 620 having a rear aperture 625 (or viewing aperture), and a rear side from the front panel 610 630 extends outwardly from the axial column 627. The safety cover 60 also includes a single shutter member 640 having a generally circular body 645 and a stem 650 extending radially from the body. The side wall 605 of the housing 600 also includes a slot 660 that can be passed by the shutter member 640. In other embodiments, the safety cover 60 also includes an eye cup 670 that is secured to the back panel 620.

The operation of the device will be described with reference to Figures 7A and 7B. As shown, the pivoting of the lever 650 (shown by arrow F3) drives the body 645 of the shutter member 640 out of alignment with the viewing aperture 625, thereby allowing the inner observer to see through the door viewing mirror assembly. Release of the lever 650 returns the shutter member 640 to its normal closed position by gravity.

8 to 10 show an aspect of a door viewing mirror device in another aspect of the creation Full cover. As shown, the security cover 80 includes a housing 800; the housing 800 includes a side wall 805 having an outer edge 807, an annular front plate 810 having a front aperture 815, and an annular rear plate 820 having a rear aperture 825 (or viewing aperture). . As shown, the outer edge 807 is further coated with a binder 840 that is covered by the release paper 845.

Referring to Figures 9A and 9B, the shutter mechanism is optical comprising a plurality of blades 905A-905F The diaphragm 900; the blade is pivotally coupled to the rear side of the front panel 810 by a post (column not shown) extending from the rear side of the front panel using a method similar to that described above. Each blade 905A-905F is generally in the shape of a teardrop that includes a narrow proximal end and a broad distal end. Each blade includes a follower pin 910A-910F disposed adjacent the outer edge of the blade along an intermediate position of the blade. In addition, the rear panel 820 also includes a plurality of radial slots 815A-815F that are angularly spaced apart on the board. Each of the follower pins 910A-910F is disposed in its corresponding slot 815A-815F, wherein the slot defines the path of movement of each blade. However, it should be understood that the diaphragm 900 can have any number of blades. In addition, each blade may have any size and shape suitable for its description, such as a polygon or the like.

Referring to Figures 10A-10C, with this configuration, the rotation of the rear plate 820 (by arrow R4) Shown) causing each of the follower pins 910A-910F to move along their respective slots 815A-815F, pivoting each blade 905A-905F radially, rotating the blades from the open position, with each blade moving away from the front aperture 815 (Fig. 10A) to the closed position (Fig. 10C), in the closed position, each blade at least partially blocks the front aperture (Fig. 10C). This is the wider end of the blade, i.e., the distal end of the blade, at least partially covering the front aperture 815 in the closed position. To close the shutter mechanism, the rear plate 820 is rotated in the opposite direction.

Figure 11 shows a security cover for a door viewer device in an aspect of the present invention. Such as As shown, the security cover 1100 includes a structure similar to that described in Figures 1A and 1B. However, in this configuration, the biasing member 1105 is a coil spring that is coupled to the distal end of the second shutter member 1110B. As shown In the embodiment described in 1A, the movement of the second shutter member 1110B produces a corresponding movement in the first shutter member 1110A.

Figures 12 to 18 show the safety of the door viewer in another aspect of the creation cover. Referring to Figures 12A and 12B, the lid assembly 1200 includes a base member 1205 (or a connector) and a shutter assembly 1210 coupled to the base member. The base member 1205 is configured to connect the shutter assembly 1210 to the surface of the door containing the door viewer. Referring to Figures 13A through 13D, the base member 1205 includes a body 1305 having a door side 1310A (or a first end, a side or a door end) and a shutter side 1310B (or a second end, side or shutter end). The body 1305 can be generally annular, including a central opening 1312 (or aperture) defined by the inner wall 1315. The main body 1305 may gradually become tapered toward the shutter side 1310B, that is, the outer diameter of the main body toward the door side 1310A is wider, and the outer diameter of the main body toward the shutter side 1310B is narrower. In other words, the body 1305 can be generally frustoconical. Accordingly, the diameter of the opening 1312 along the gate side 1310A can be larger than the diameter of the opening 1312 along the valve side 1310B.

The base member 1205 also includes one or more axial guide walls that are oriented from the body 1305 The shutter surface 1310B extends outward. In the illustrated embodiment, the base member 1205 includes three axial guide walls 1320A, 1320B, 1320C that are angularly spaced apart along the body inner perimeter 1322, for example, walls 1320A through 1320C can be equally spaced. Each of the guide walls 1320A-1320C can have a predetermined angular length across the body. For example, the first guide wall may extend about 25° to 35° along the inner perimeter of the body 1305 defined by the inner wall 1315, while the second guide wall 1320A and the third guide wall 1320C may each define along the inner wall 1315. The inner perimeter of the body extends approximately 45° to 55°. It should be understood that the guide walls 1320A-1320C can have any size (height, width, length) and shape suitable for their purpose. Additionally, body 1305 can include any number of guide walls. In operation, the guide walls 1320A-1320C engage the inner surface of the shutter member housing during attachment to the base member to retain the shutter member in its position.

The surface of the base member 1205 to the door side 1310A can be modified to connect the base member to Door surface. For example, the door side surface may be coated with a layer of an adhesive such as a pressure sensitive adhesive and optionally covered with a release paper. Alternatively, the body 1305 can be modified to allow the use of fasteners, such as a fastener (screw) channel, for the fastener to pass.

The base member 1205 also includes a coupling mechanism operatively associated with the shutter assembly 1210 The corresponding connecting mechanism is matched to connect the shutter assembly to the base member. For example, the base member 1205 can include one or more axial recesses and/or hooks to secure corresponding components on the shutter housing. Referring to Figure 13A, the base member 1205 includes a plurality of axial recesses that extend axially through the body 1305 at a predetermined angular position. In the illustrated embodiment, the attachment mechanism includes three axial recesses 1325A, 1325B, 1325C that are angularly spaced apart on the body 1305, wherein each axial recess is disposed in an adjacent axial wall 1320A-1320C between. The recesses 1325A-1325C can have any shape and size suitable for their stated purpose. In the illustrated embodiment, the recesses 1325A-1325C are polygonal and extend radially to the body 1305.

The attachment mechanism can also include one or more hooks that are operatively coupled to the living The corresponding locking tab of the door assembly. In the illustrated embodiment, the attachment mechanism includes three hooks 1330A, 1330B, 1330C; each hook is associated with a respective recess 1325A-1325C. Each hook 1330A-1330C extends axially from the body 1305 toward the shutter side 1310B and is generally radially aligned with the corresponding recess 1320A-1320C. Referring to Figure 14, each hook 1330A-1330C is generally L-shaped and includes an axial arm 1405 extending outwardly from the base body 1305 and a radial arm extending radially inward from the distal end of the axial arm. The portion 1410 extends the radial arm portion over at least a portion of the recess 1325A-1325C. The hooks 1330A-1330C further include an open side end 1415 and a closed side end 1420 (consisting of lateral side walls). Thus, the hooks 1330A-1330C are defined as a slot that receives the locking tabs disposed on the shutter assembly 1210 through the open side end 1415 defined by the hooks. The closed side end 1420 is used as a stop for preventing the lock in the hook The rotation of the flap and the rotation of the shutter assembly exceed the closed side end. That is, when the locking tabs of the shutter assembly 1210 are positioned within the hooks 1330A-1330C, the locking tabs are secured, wherein the hooks secure the shutter assembly to the base member 1205.

Referring to Figures 15A-15E, the shutter assembly 1210 includes a shutter portion 1505 and a connection (example) If installed, the eye cup portion 1510 of the shutter portion. The shutter portion 1505 includes a housing 1515 having a front side 1520A (or a first side, end or front end) that is coupled to the base member 1205 and a rear side 1520B (or a second side, end or rear end) that is coupled to the eye cup 1510. . The housing 1515 can be generally annular with an inner surface 1522 of the housing defining a passage 1525 (or opening). The housing 1515 can taper in a rearward direction such that the diameter of the channel 1525 along the front side 1520A is greater than the diameter of the channel 1525 along the back side 1520B (eg, the housing can be generally frustoconical). The housing 1515 also includes a long slot 1527 disposed along the rear side 1520B of the housing and generally aligned with a shutter mechanism disposed within the housing. This will be discussed in more detail below.

As described above, a plurality of locking elements or locking tabs are configured with hooks on the base member 1205. 1330A-1330C matches. The locking element or locking tab can be disposed at a desired angular position on the outer surface 1532 of the body. In the illustrated embodiment, the housing 1515 includes three locking tabs 1530A, 1530B, 1530C, wherein each locking tab extends radially from the body outer surface 1532 of the front end 1520A of the housing 1515; the angularly spaced locking tabs Align with the corresponding hooks 1330A-1330C on the base member 1205. Referring to Figure 15E, each of the locking tabs 1530A-1530C includes a generally transverse member having a front edge portion 1535 and a beveled edge portion 1540 (or an angular shape). The locking tabs 1530A, 1530B, 1530C also include a generally vertical member 1545 disposed proximate the angled edge 1540. In operation, the front edge 1535 enters the slot formed by the hooks 1330A-1330C during the attachment of the shutter assembly 1210 to the base member 1205. This ultimately enables the shutter assembly to be selectively coupled to the base member. This will be discussed in more detail below.

Eye cup portion 1510 is configured to be able to mask ambient light. In one embodiment, The eye cup portion 1510 includes an eye cup having a base portion 1546 that is coupled to a rear end 1520B of the housing 1515 and an outer edge portion 1547 that extends rearward from the base portion. The base portion 1546 can be generally frustoconical. The rim portion 1547 can be a solid wall made of a light-shielding material surrounding the aperture 1610 (Fig. 16). For example, the eye cup can be composed of a hard plastic or an elastic material such as an elastomer, rubber, or the like. As shown, the eye cup can be generally concave, initially curved inwardly and then outwardly curved along its rear end 1548 (toward the user's end). The contour of the rear end 1548 of the rim portion 1547 can be designed to conform to the shape of the eye. With this configuration, placing the eye close to the outer edge portion 1547 allows the eye cup to enclose the eye and prevent light from passing through.

Referring to Figure 16, the wall 1605 is disposed adjacent the housing 1515 of the housing rear side 1520B. Inside. The wall 1605 includes a bore 1610 having a diameter that is less than the diameter of the housing passage 1525. As shown, the aperture 1610 can be generally elliptical. The shutter assembly 1210 houses a shutter mechanism that operatively controls the amount of light passing through the housing 1515 by selectively covering the aperture 1610. Referring to Figure 15B, the shutter mechanism includes a fixed mask layer 1550 and a resettable mask layer 1555 (or diaphragm). The fixed mask layer 1550 can be a generally semi-annular planar member, i.e., a C-shaped planar member that extends radially inward from the inner surface 1522 of the housing 1515. Additionally, the fixed mask layer 1550 extends at a limited portion of the inner channel 1525 of the body. For example, the fixed mask layer can extend about 90° in the shutter channel 1525. With this configuration, the fixed mask layer can partially block the inner channel 1610. In operation, the fixed mask layer 1550 acts as a support for the resettable mask layer 1555, supporting the resettable mask layer in its closed position and moving from its closed position to the resettable mask layer When it is in the open position, the guide can reset the mask layer.

The resettable mask layer 1555 mates with the fixed mask layer to allow selective viewing of the lens of the peephole; the resettable mask layer 1555 includes a cover and an actuator in communication with the cover, operating the actuator The cover corresponding housing 1515 and aperture 1610 will be reset. In the embodiment shown in Figure 16, the resettable mask layer 1555 includes a generally semi-circular cover or disk portion 1625 and an actuator 1630 (or an actuator arm or extending outwardly from the upper region of the cover portion). Rod). The disk portion 1625 can be generally planar and sized larger than the aperture 1610; thus, when the disk portion is aligned with the aperture, the aperture is substantially or completely covered to prevent light from passing through the housing 1515. The resettable mask layer 1555 is pivotally coupled to the housing wall 1605 by a pivot post 1635; the pivot post extends axially along the housing or channel axis from the front surface of the wall (facing the surface of the base) and is actuated along The intermediate position of the device 1630 is set. The thickness of the disk 1625 is slightly less than the width of the groove 1527 formed in the housing 1515. Accordingly, as the disk 1625 passes through the slot, it substantially blocks light and prevents light from entering the housing 1515 through the slot 1527.

The first stop member 1640 (or rib) extends from the front surface 1620 of the housing wall 1605 Stretch. The first stop member engages the disk 1625 to prevent the disk 1625 from rotating beyond the predetermined angular position in the first direction (clockwise from the angle of Figure 16). For example, the stop member prevents the disc 1625 from rotating excessively when rotated to its closed position, ensuring that the disc blocks the aperture in its closed position. Additionally, the disk 1625 can include a second stop member 1645 extending from a front side thereof. The second stop member 1645 is configured to prevent the disk from excessively rotating in the second direction (counterclockwise from the angle of FIG. 16). For example, the second stop member 1645 engages the inner surface 1522 of the housing 1515 proximate the slot 1527 to prevent the disk from completely passing through the slot and away from the housing. As shown, the first stop member 1640 and the second stop member 1645 can be substantially elongated protrusions.

With this configuration, a downward force is applied to the actuator 1630 (as indicated by arrow F), The disc 1625 is rotated (as indicated by arrow R) and is not aligned with the aperture 1610 to allow light to pass through the shutter assembly 1210 and allow the viewer to see through the safety cover 1200. The user can rotate the disk until the second stop member 1645 engages the housing 1515. The configuration of the resettable mask layer 1555 is eccentrically emphasized, making it easy to release The actuator 1630 can allow gravity to rotate the disk 1625 back to its closed position in which the disk is aligned with the aperture 1610. Alternatively, an opposing (upward) force is applied to rotate the disk 1625 (clockwise from the angle of Figure 16) until the disk engages the first stop member 1640, returning the resettable mask layer 1555 to its normal closed position. It should be understood that while the shutter assembly is illustrated as an integral (single piece) configuration, in other embodiments, the disk portion 1625 and the actuator 1630 can be separate components that are interconnected.

With this configuration, the fixed mask cover 1550 and the resettable mask layer 1555 are mated to Used as an aperture stop that controls the field of view of the shutter assembly 1210. In a sense, the shutter mechanism acts as a field stop that can be reset to selectively block the aperture 1610 of the housing 1515, thereby blocking light from passing through, i.e., the shutter mechanism blocks the user from seeing through the eye cup 1510. Valve assembly.

The operation of the apparatus will be described with reference to Figs. 17A and 17B. Initially, the base member 1205 The peephole 1705 of the door 1710 is aligned such that the base member 1205 is substantially coaxial with the peephole viewing mirror. The base member 1205 is secured to the door, such as removing the release paper and pressing the base member against the door surface. When the base member 1205 is secured to the door, the shutter assembly connects the base member. Specifically, the shutter assembly 1210 is aligned with the base member 1205 and rotationally oriented to position the locking tabs 1530A, 1530B, 1530C adjacent the hook opening side ends 1415. The shutter assembly 1210 is axially advanced to the base member 1205 and then rotated (clockwise from the angle of Figure 17B) to cause the locking tabs 1530A-1530C to slide under the hooks 1330A-1330C. The process of removing the shutter assembly 1210 is reversed and the shutter assembly is rotated in the opposite direction (e.g., counterclockwise) until the locking tabs 1530A-1530C are removed from the hooks 1330A-1330C. After removal, the shutter assembly 1210 exits the base member to separate the components.

In operation, device 1200 begins in its normally closed position, wherein resettable masking The cover layer 1555 mates with the fixed mask layer 1550 to cover the aperture 1610 of the housing 1515. To pass through the peephole The article is viewed safely, the user approaches the eye cup 1510 and then pivots the actuator 1630 to position the device in the viewing position. In particular, the actuator 1630 is pivoted to drive the disk 1625 to move radially outwardly, passing the disk through the slot 1527 and partially or completely removed from the aperture 1610, ie, no longer aligned with the aperture 1610. As noted above, the disk 1625 can be rotated until the second stop member 1645 engages the housing wall proximate the slot 1527. Thus, in the normal position, the disk 1625 can be completely disposed within the housing. In the viewing position, the disk 1625 extends partially out of the housing 1515 through the slot 1527.

At the viewing position, the observer can now see through the security device 1200 and the peephole 1705. The thickness of the resettable mask layer 1555 is slightly less than the width of the slot 1527 (alternatively, the thickness of the actuator 1630 can also be slightly less than the width of the slot 1527); therefore, it prevents light from penetrating through the slot into the housing 1515. . After viewing, the user simply releases the actuator 1630, allowing gravity to return the mask layer 1555 to its normal closed position. Alternatively, the user can manually rotate the actuator 1635 in the opposite direction, pivoting the resettable mask layer 1555 back to its normal closed position. The user can now remove the eye from the eye cup 1510.
