Description

The present invention relates to fixtures.

Display cases (furniture) for displaying items are known. For example, Patent Document 1 describes a display case equipped with a locking device for locking the cover.

Patent No. 5359503

In the display case of Patent Document 1, the key slot for inserting the key to unlock the cover is provided on the front of the display case. This means that the key slot is easily noticeable, which can cause problems with the appearance of the display case.

In view of the above circumstances, one of the objectives of the present invention is to provide fixtures that are equipped with a locking device and have a structure that can prevent them from becoming unsightly.

In order to solve the above problems, the present invention employs the following aspects.
(1) One aspect of the fixture of the present invention comprises a storage section having a transparent window section and in which items are stored, and a support section installed on a floor surface and supporting the storage section at a position above the floor surface, the storage section having a base member having a placement section on which the items are placed, a cover member supported on the base member so as to be openable and closable, and a locking device provided on the base member and switchable between an unlocked state in which the cover member can be opened and closed relative to the base member and a locked state in which the cover member cannot be opened or closed relative to the base member, the locking device having a locking section formed with a keyhole into which a key can be inserted to switch the state of the locking device between the unlocked state and the locked state, the locking section being provided on the underside of the base member.

According to one aspect of the fixture of the present invention, when the fixture is viewed from the outside, the keyhole formed in the locking section is not easily noticeable. This prevents the appearance of the fixture from being ruined. In addition, because the keyhole is not easily noticeable, it is possible to prevent the locking device from being improperly unlocked through the keyhole. This improves the safety of the items stored in the storage section.

(2) In the fixture relating to the above aspect (1), the base member may have a bottom portion supporting the storage portion from below, the locking device being supported by the bottom portion, the locking device being provided on an underside of the bottom portion, and the storage portion having a portion covering at least a portion of the locking device from above.
According to this aspect, the placement portion can prevent the locking device from being seen from above. This allows the locking portion to be provided on the underside of the bottom portion while preventing other portions of the locking device from being conspicuous. This further prevents the appearance of the fixture from being ruined. In addition, since it is difficult to tell where the locking device is provided on the fixture, it is further prevented that the locking device is in an inappropriately unlocked state through the keyhole. This further improves the safety of the items stored in the storage portion. In addition, since there is no need to provide a separate portion for storing the locking device outside the placement portion, it is easy to make the fixture smaller. In addition, the locking device can be prevented from protruding above the placement portion, and the storage space formed on the placement portion can be prevented from being narrowed by the locking device. This makes it easy to ensure a wide storage space for storing items in the storage portion.

(3) In the fixture relating to the aspect (2) above, the cover member may be box-shaped and open downward, the lower end of the cover member may be supported on the bottom and arranged to surround the storage portion, the locking device may have a locking portion that moves in response to operation of the key inserted in the keyhole, and a locking portion to which the locking portion can be locked may be formed in a portion of the cover member arranged around the storage portion, so that in the locked state the locking portion is locked to the locking portion and in the unlocked state the locking portion is released from its locking engagement with the locking portion.
According to this aspect, the state of the locking device can be easily and suitably switched between the unlocked state and the locked state by using a simple structure in which the locking portion is moved by operating the key inserted in the keyhole.

(4) In a fixture relating to any one of the above aspects (1) to (3), the support part may have a support part main body surrounding a space provided below the base member and having an opening connected to the space, and a cover member removably attached to the support part main body and covering at least a portion of the opening, and the locking part may be configured to face the space.
According to this aspect, by covering the periphery of the space with the support body and the lid member, the part of the lower surface of the base member where the locking part is provided can be made difficult to see from the outside. This can further prevent the appearance of the fixture from being deteriorated. In addition, it can further prevent the locking device from being in an unlocked state through the keyhole. Therefore, the safety of the items stored in the storage part can be further improved. In addition, since the lid member is detachable from the support body, it is easy to insert a key into the keyhole and switch the state of the locking device by removing the lid member from the support body. In addition, since the support surrounds the space provided below the base member, the appearance of the fixture can be made solid and stable. In addition, since the lid member constituting a part of the support can be removed, removing the lid member can make it easier to clean the floor surface facing the space surrounded by the support.

(5) In the fixture relating to the aspect (4) above, the lid member may have a locking claw, and the support body may be formed with a locking hole into which the locking claw is inserted so that the locking claw is locked from above, and the upper end of the lid member may be located lower than the upper end of the opening, and a covering member may be fixed to the underside of the storage section, and the covering member may be positioned within the space opposite a portion of the opening that is located higher than the lid member.
According to this aspect, the cover member can be detachably attached to the support body by a simple structure in which the locking claw is hooked from above into the locking hole. This makes it easy to remove the cover member from the support body, and the operation of switching the state of the locking device can be easily performed. In addition, the floor surface facing the space enclosed by the support can be easily cleaned.
According to this aspect, the covering member can cover the portion of the opening located above the lid member from inside the space, and the inside of the space surrounded by the support part can be prevented from being seen from outside the fixture. This makes it more difficult to see the locking part facing the space from outside the fixture. Therefore, the appearance of the fixture can be prevented from being damaged. In addition, the locking device can be prevented from being unlocked improperly through the keyhole, and the safety of the items stored in the storage part can be improved.

(6) In the fixture relating to any one of the above aspects (1) to (5), the base member may extend in one direction, and the locking device may be provided at each of both ends of the base member in the one direction.
According to this aspect, the cover member can be suitably locked to the base member by the pair of locking devices.

According to one aspect of the present invention, it is possible to prevent fixtures equipped with locking devices from becoming unsightly.

The placement section 42 is a portion on which items to be stored in the storage section 20, i.e., the storage space S1, are placed. In this embodiment, the placement section 42 is a roughly rectangular parallelepiped member that is thin in the vertical direction Z and long in the left-right direction Y. The outer edge of the placement section 42 is supported from below by the bottom section 41a. The placement section 42 covers the entire inner space surrounded by the frame-shaped bottom section 41a from above. The lower surface of the portion of the placement section 42 that is located inside the frame-shaped bottom section 41a when viewed in the vertical direction Z forms part of the lower surface of the storage section 20 and faces the space S2.

The mounting portion 42 is disposed inside the frame-shaped protruding wall portion 41b. The mounting portion 42 is disposed slightly away from the inner peripheral surface of the protruding wall portion 41b. As a result, a frame-shaped groove portion 43 that is recessed downward is formed between the mounting portion 42 and the protruding wall portion 41b. The frame-shaped groove portion 43 is formed all around along the outer peripheral surface of the mounting portion 42 and the inner peripheral surface of the protruding wall portion 41b. In this embodiment, the frame-shaped groove portion 43 is a rectangular frame-shaped groove that is long in the left-right direction Y.

The front plate 33 is a rectangular plate that is long in the left-right direction Y. The front plate 33 is disposed in front of the back plate 31, facing it with a gap therebetween. The upper end of the front plate 33 is located lower than the upper end of the back plate 31.

The upper plate 34 forms the upper wall of the cover member 30. The upper plate 34 connects the upper end of the back plate 31 and the upper end of the front plate 33. The upper plate 34 has a horizontal portion 34a and an inclined portion 34b. The horizontal portion 34a is a portion whose plate surface extends in the horizontal direction perpendicular to the vertical direction Z. The horizontal portion 34a is a rectangular plate that is long in the left-right direction Y. The rear end of the horizontal portion 34a is connected to the upper end of the back plate 31. The inclined portion 34b is connected to the front end of the horizontal portion 34a. The inclined portion 34b is located downward as it moves forward (+X direction) from the horizontal portion 34a. The upper surface of the inclined portion 34b faces upward and diagonally forward. The front end of the inclined portion 34b is connected to the upper end of the front plate 33.

The pair of side panels 35 form each wall portion of the cover member 30 in the left-right direction Y. The plate surfaces of the pair of side panels 35 face the left-right direction Y. The pair of side panels 35 are arranged with a gap in between in the left-right direction Y. The pair of side panels 35 are trapezoidal when viewed in the left-right direction Y. The upper ends of the pair of side panels 35 are connected to both ends of the top panel 34 in the left-right direction Y. The pair of side panels 35 connect both ends of the back panel 31 in the left-right direction Y to both ends of the front panel 33 in the left-right direction Y.

The pair of side panels 35 each have a protruding piece 35a protruding downward at the center in the front-rear direction X at the lower end. Each protruding piece 35a has an interlocking portion 35b formed thereon. In this embodiment, the interlocking portion 35b is a hole that penetrates the protruding piece 35a in the left-right direction Y. The interlocking portion 35b is a rectangular hole that is long in the front-rear direction X. The protruding piece 35a is the portion that is inserted into the frame-shaped groove portion 43, and is part of the portion of the cover member 30 that is arranged around the mounting portion 42.

The back panel 31 and the window portion 32 are preferably made of the same material.

The operating device 53 has an operating unit 53a. The operating unit 53a is a part that is operated when changing the environment inside the storage unit 20, i.e., the environment of the storage space S1. In this embodiment, the operating unit 53a is a switch that can switch the state of the lighting device 50 between a turned-on state and a turned-off state. In other words, when the operating unit 53a, which is a switch, is turned on, the light source of the lighting main body 52 in the lighting device 50 is turned on, and when the operating unit 53a is turned off, the light source of the lighting main body 52 is turned off.

The operating unit 53a is provided at the lower end of the operating device 53. The operating unit 53a is provided on the underside of the storage unit 20. Note that "the operating unit 53a is provided on the underside of the storage unit 20" means that the operating unit 53a can be seen when the part of the underside of the storage unit 20 where the operating unit 53a is located is viewed from below. Also, the underside of the storage unit 20 can be a part that can be seen when the storage unit 20 is viewed from below. In this embodiment, the underside of the storage unit 20 includes the underside of the bottom 41a and the underside of the placement unit 42.

In this embodiment, the operating unit 53a is provided on the underside of the bottom 41a. More specifically, the operating unit 53a is provided on a portion of the underside of the bottom 41a that is located forward (+X direction) of the portion to which the covering member 70 is fixed. In this embodiment, the operating unit 53a is provided on a portion of the underside of the storage unit 20 that forms the inner surface of the groove 80. More specifically, the operating unit 53a is provided on the rear portion of the upper portion of the inner surface of the groove 80. The operating unit 53a is disposed above the inclined wall portion 73 of the covering member 70, facing the inclined wall portion 73 with a gap therebetween.

As shown in FIG. 7, the lighting device 50 has wiring 54 that electrically connects the operating device 53 and the lighting main body 52. The wiring 54 extends backward (towards -X) on the bottom 41a from the upper end of the operating device 53 to the lower end of the support column 51 on the right side (+Y side). The wiring 54 is routed from the lower end of the support column 51 into the support column 51, extends upward inside the support column 51 and is connected to the lighting main body 52.

The fixture 100 is equipped with a locking device 60 provided on the base member 40. The locking device 60 is a device that can be switched between an unlocked state US in which the cover member 30 can be opened and closed relative to the base member 40, and a locked state LS in which the cover member 30 cannot be opened and closed relative to the base member 40. In the unlocked state US, as shown in FIG. 3, the cover member 30 can be removed upward from the base member 40 and opened. On the other hand, in the locked state LS, the cover member 30 cannot be removed from the base member 40, and the cover member 30 cannot be opened.

As shown in FIG. 1, in this embodiment, the locking devices 60 are provided at both ends of the base member 40 in the left-right direction Y. The pair of locking devices 60 have the same configuration, except that they are arranged symmetrically in the left-right direction Y. Therefore, in the following description, there are cases where only the locking device 60 located on the right side (+Y side) is described as a representative of the pair of locking devices 60.

As shown in FIG. 7, the locking device 60 is supported on the bottom 41a. More specifically, the locking device 60 is supported on the center of the bottom 41a in the front-rear direction X at the outer edge in the left-right direction. As shown in FIG. 10 and FIG. 11, at least a part of the locking device 60 is housed in a recess 42a formed in the mounting portion 42. The wall portion 42b of the mounting portion 42 located on the upper side of the recess 42a is located above the locking device 60 and covers at least a part of the locking device 60 from above. In other words, the mounting portion 42 has the wall portion 42b as a part that covers at least a part of the locking device 60 from above. In this embodiment, the wall portion 42b covers almost the entire locking device 60 from above.

The locking device 60 has a base 61 and a locking portion 62. The base 61 is columnar and extends in the vertical direction Z. The base 61 extends upward from the bottom 41a. The base 61 is fixed to the bottom 41a by a fixing bracket 63. The lower end of the base 61 is a locking portion 64 in which a keyhole 64a is formed. The keyhole 64a is a hole into which a key is inserted to switch the state of the locking device 60 between the unlocked state US and the locked state LS. The keyhole 64a opens on the underside of the locking portion 64. The keyhole 64a opens downward and into the space S2.

The locking part 64 is fitted into a hole 41d that penetrates the bottom part 41a in the vertical direction Z. In this embodiment, the lower surface of the locking part 64 is located at the same position as the lower surface of the bottom part 41a in the vertical direction Z. The lower surface of the locking part 64 may protrude downward from the lower surface of the bottom part 41a, or may be located at a position recessed upward from the lower surface of the bottom part 41a.

The underside of the locking unit 64 is provided on the underside of the bottom 41a. As a result, the locking unit 64 is provided on the underside of the base member 40. Note that "locking unit 64 is provided on the underside of the base member 40" means that the locking unit 64 is visible when the part of the underside of the base member 40 where the locking unit 64 is located is viewed from below. Also, the underside of the base member 40 means a part that is visible when the base member 40 is viewed from below. The underside of the base member 40 is the underside of the storage unit 20.

As shown in FIG. 4, the locking unit 64 has a circular shape when viewed from below. In this embodiment, the locking unit 64 is provided facing the space S2. The locking unit 64 is provided on a portion of the lower surface of the bottom 41a that is located rearward (toward the -X side) from the covering member 70. In this embodiment, the locking unit 64 is provided on a portion of the lower surface of the base member 40 that is closer to the front (toward the +X side).

As shown in Figures 10 and 11, the locking portion 62 protrudes outward in the left-right direction from the upper end of the base 61. In this embodiment, the locking portion 62 is a sheet metal member. The locking portion 62 has a first extension portion 62a extending outward in the left-right direction from the base 61, a second extension portion 62b extending downward from the outer end of the first extension portion 62a in the left-right direction, and a third extension portion 62c extending outward in the left-right direction from the lower end of the second extension portion 62b.

The locking portion 62 moves in the left-right direction Y in response to the operation of the key inserted in the keyhole 64a. Specifically, when the key inserted in the keyhole 64a is turned and the locking device 60 is switched from the locked state LS to the unlocked state US, the locking portion 62 moves inward in the left-right direction relative to the base 61. When the key inserted in the keyhole 64a is turned and the locking device 60 is switched from the unlocked state US to the locked state LS, the locking portion 62 moves outward in the left-right direction relative to the base 61.

As shown in FIG. 10, in the locked state LS, the outer end in the left-right direction of the third extension 62c of the engaging portion 62 is inserted into the engaged portion 35b formed in the portion of the cover member 30 arranged around the placement portion 42. As a result, in the locked state LS, the engaging portion 62 is engaged with the engaged portion 35b. Therefore, even if an attempt is made to lift the cover member 30 upward in the locked state LS, the engaging portion 62 is caught on the inner edge of the engaged portion 35b from below, preventing the cover member 30 from moving upward. In this embodiment, the engaging portions 62 of the pair of locking devices 60 are engaged with the pair of engaged portions 35b, respectively, preventing the cover member 30 from being removed from the base member 40.

As shown in FIG. 11, in the unlocked state US, the entirety of the locking portion 62 is located laterally inward of the locked portion 35b. In other words, in the unlocked state US, the third extension portion 62c of the locking portion 62 is not inserted into the locked portion 35b, and the locking portion 62 is not locked to the locked portion 35b. Thus, in the unlocked state US, the locking portion 62 is released from the locked portion 35b. In this embodiment, by setting the pair of locking devices 60 to the unlocked state US, it is possible to remove the cover member 30 from the base member 40 and open it.

According to this embodiment, the fixture 100 includes a storage section 20 having a transparent window section 32 and in which an item is stored, and a support section 10 that is installed on a floor surface F and supports the storage section 20 at a position above the floor surface F. The storage section 20 includes a base member 40 having a placement section 42 on which an item is placed, a cover member 30 supported on the base member 40 so as to be openable and closable, and a locking device 60 provided on the base member 40 and capable of switching between an unlocked state US in which the cover member 30 can be opened and closed relative to the base member 40, and a locked state LS in which the cover member 30 cannot be opened and closed relative to the base member 40. The locking device 60 has a locking section 64 having a keyhole 64a formed therein in which a key is inserted to switch the state of the locking device 60 between the unlocked state US and the locked state LS. The locking section 64 is provided on the underside of the base member 40. Therefore, when the fixture 100 is viewed from the outside, the keyhole 64a formed in the locking section 64 is not easily noticeable. This prevents the appearance of the fixture 100 from being ruined. In addition, because the keyhole 64a is not easily noticeable, it is possible to prevent the locking device 60 from being improperly placed in the unlocked state US via the keyhole 64a. This improves the safety of the items stored in the storage section 20.

In addition, according to this embodiment, the base member 40 has a bottom 41a that supports the placement portion 42 from below. The locking device 60 is supported by the bottom 41a. The locking portion 64 is provided on the lower surface of the bottom 41a. The placement portion 42 has a portion that covers at least a part of the locking device 60 from above, i.e., the wall portion 42b. Therefore, the wall portion 42b of the placement portion 42 can prevent the locking device 60 from being visible from above. This makes it possible to provide the locking portion 64 on the lower surface of the bottom 41a while preventing other parts of the locking device 60 from being conspicuous. Therefore, it is possible to further prevent the appearance of the fixture 100 from being deteriorated. In addition, since it is difficult to know where the locking device 60 is provided on the fixture 100, it is possible to further prevent the locking device 60 from being unfairly put into the unlocked state US through the keyhole 64a. Therefore, the safety of the items stored in the storage portion 20 can be further improved. In addition, since there is no need to provide a separate section for housing the locking device 60 outside the placement section 42, the fixture 100 can be made smaller. In addition, the locking device 60 can be prevented from protruding above the placement section 42, and the storage space S1 formed above the placement section 42 can be prevented from being narrowed by the locking device 60. Therefore, it is easy to ensure a wide storage space S1 for storing items in the storage section 20.

In addition, according to this embodiment, the cover member 30 is box-shaped and opens downward. The lower end of the cover member 30 is supported by the bottom 41a and is arranged to surround the mounting portion 42. The locking device 60 has an engaging portion 62 that moves in response to the operation of a key inserted in the keyhole 64a. A locked portion 35b to which the engaging portion 62 is engaged is formed in a portion of the cover member 30 arranged around the mounting portion 42. In the locked state LS, the engaging portion 62 is engaged with the locked portion 35b, and in the unlocked state US, the engaging portion 62 is released from the locked portion 35b. Therefore, the state of the locking device 60 can be easily and suitably switched between the unlocked state US and the locked state LS by a simple structure in which the engaging portion 62 is moved by operating the key inserted in the keyhole 64a.

According to this embodiment, the support unit 10 includes a support unit body 10a that surrounds the space S2 provided below the base member 40 and has an opening 10b that connects to the space S2, and a cover member 11 that is detachably attached to the support unit body 10a and covers at least a part of the opening 10b. The locking unit 64 is provided facing the space S2. Therefore, by covering the periphery of the space S2 with the support unit body 10a and the cover member 11, the part of the lower surface of the base member 40 where the locking unit 64 is provided can be made difficult to see from the outside. This can further prevent the appearance of the fixture 100 from being deteriorated. In addition, it can further prevent the locking device 60 from being unfairly put into the unlocked state US through the keyhole 64a. Therefore, the safety of the items stored in the storage unit 20 can be further improved. In addition, because the cover member 11 is detachable from the support body 10a, it is easy to insert a key into the keyhole 64a and switch the state of the locking device 60 by removing the cover member 11 from the support body 10a.

In addition, because the support part 10 surrounds the space S2 provided below the base member 40, the appearance of the fixture 100 can be made solid and stable. In addition, because the lid member 11 constituting part of the support part 10 can be removed, removing the lid member 11 makes it easier to clean the floor surface F facing the space S2 surrounded by the support part 10.

In addition, according to this embodiment, the lid member 11 has a locking claw 11e. A locking hole 10c is formed in the support body 10a, into which the locking claw 11e is inserted and locked from above. Therefore, the lid member 11 can be detachably attached to the support body 10a by a simple configuration in which the locking claw 11e is hooked from above into the locking hole 10c. This makes it easy to remove the lid member 11 from the support body 10a, and makes it easy to switch the state of the locking device 60. In addition, the floor surface F facing the space S2 surrounded by the support 10 can be cleaned more easily.

In a configuration in which the locking claw 11e is hooked from above into the locking hole 10c to lock it, the upper end of the lid member 11 is located below the upper end of the opening 10b. Therefore, the lid member 11 cannot block the upper end of the opening 10b. In contrast, according to this embodiment, a covering member 70 is fixed to the lower surface of the storage section 20. The covering member 70 is arranged in the space S2 to face the part of the opening 10b located above the lid member 11. Therefore, the covering member 70 can cover the part of the opening 10b located above the lid member 11 from the inside of the space S2, and the inside of the space S2 can be prevented from being seen from the outside of the fixture 100. This makes it more difficult to see the locking section 64 provided facing the space S2 from the outside of the fixture 100. Therefore, it is possible to further prevent the appearance of the fixture 100 from being deteriorated. In addition, the locking device 60 can be more effectively prevented from being improperly put into the unlocked state US through the keyhole 64a, further improving the safety of the items stored in the storage section 20.

In addition, according to this embodiment, the base member 40 extends in one direction (left-right direction Y). The locking devices 60 are provided at both ends of the base member 40 in that one direction. Therefore, the pair of locking devices 60 can suitably lock the cover member 30 to the base member 40.

According to this embodiment, the fixture 100 is equipped with a lighting device 50 as an environment change device capable of changing the environment inside the storage unit 20. The lighting device 50 as an environment change device has an operation unit 53a that is operated when changing the environment inside the storage unit 20. The operation unit 53a is provided on the underside of the storage unit 20. Therefore, when the fixture 100 is viewed from the outside, the operation unit 53a is not easily noticeable. This makes it possible to prevent the appearance of the fixture 100 from being damaged. Furthermore, since the operation unit 53a is not easily noticeable, it is possible to prevent the operation unit 53a from being improperly operated by pranks, etc. This makes it possible to prevent the environment inside the storage unit 20 from being improperly changed.

Also, according to this embodiment, as described above, the support unit 10 has a support unit main body 10a that surrounds the space S2 provided below the storage unit 20 and has an opening 10b that connects to the space S2, and a cover member 11 that is detachably attached to the support unit main body 10a and covers at least a part of the opening 10b. Therefore, compared to a case where the support unit 10 is composed of multiple legs or the like and the space S2 is widely open to the outside, the bottom surface of the storage unit 20 can be made less noticeable. This makes it possible to more effectively prevent the operation unit 53a provided on the bottom surface of the storage unit 20 from being noticeable, and more effectively prevent the appearance of the fixture 100 from being impaired. In addition, it is possible to more effectively prevent the operation unit 53a from being improperly operated, and more effectively prevent the environment inside the storage unit 20 from being improperly changed.

According to this embodiment, the lid member 11 is disposed below the underside of the storage unit 20, facing the gap G. A groove 80 is formed between the lid member 11 and the underside of the storage unit 20, opening in the direction in which the opening 10b opens, i.e., facing forward. The operation unit 53a is provided on a portion of the underside of the storage unit 20 that forms the inner surface of the groove 80. Therefore, an operator who properly operates the operation unit 53a can easily operate the operation unit 53a by inserting his/her hand into the groove 80 from the front. This makes it possible to easily operate the operation unit 53a while preventing the appearance of the fixture 100 from being deteriorated by providing the operation unit 53a on the underside of the storage unit 20.

In addition, according to this embodiment, the covering member 70 is disposed in a position facing the gap G in the space S2. The groove 80 is formed by the cover member 11, the underside of the storage section 20, and the covering member 70. Therefore, as described above, the covering member 70 makes it difficult to see inside the space S2 from outside the fixture 100, improving the appearance of the fixture 100 and allowing the groove 80 to be formed appropriately. In addition, the covering member 70 can prevent the operator's hand inserted into the groove 80 from entering the space S2, and the operator can easily find the operating unit 53a by touching the upper part of the inner surface of the groove 80 with the hand inserted into the groove 80. This makes it easier to operate the operating unit 53a.

According to this embodiment, the environment change device is a lighting device 50. The operation unit 53a is a switch that can switch the state of the lighting device 50 between a turned-on state and a turned-off state. Therefore, the lighting device 50 can change the inside of the storage unit 20 to a bright state. This allows the light emitted from the lighting device 50 to illuminate the items in the storage unit 20. Therefore, the items stored in the storage unit 20 can be easily viewed from outside the fixture 100 through the transparent window portion 32.
