For years, “child-proof” safety latches have been designed and used, primarily in households, to prevent access by young children to drawers and doors of cabinets that may store potentially harmful or dangerous items. Such safety latches are typically designed to be difficult for young children to operate, but may be easily operated by an adult.
Unfortunately, previous safety latches have experienced a variety of drawbacks. For example, in some cases installation and proper adjustment of the safety latches can be time-consuming and difficult especially in the confined cabinet spaces in which such safety latches are typically employed. Additionally, some existing safety latches can cause the cabinet surfaces on which the latch operates to become marred or damaged due to the manner in which the safety latch is secured to the cabinet. Further, some existing safety latches operate by allowing the door or drawer panel to be opened to a limited extent, in order to activate or deactivate the latch mechanism. With such safety latches, this slight opening of the cabinet door or drawer can result in babies and/or young children getting their fingers pinched between the door or drawer and the body of the cabinet. Still further, other existing safety latches may present cost problems, may be fairly complex to operate and/or may be prone to operation failure.
The present invention is directed to a latch assembly for use with a cabinet that includes a cabinet body and a moving component. The latch assembly comprises a transverse member and a pivoting member. The transverse member is selectively coupled to the cabinet body. The pivoting member is pivotally secured to the transverse member. Additionally, the pivoting member pivots relative to the transverse member between a first position in which the pivoting member inhibits large scale movement of the moving component relative to the cabinet body, and a second position in which the pivoting member allows for large scale movement of the moving component relative to the cabinet body.
In certain, non-exclusive embodiments, the term large scale movement shall mean movement of greater than approximately 3, 2, 1, 0.5, 0.3, 0.2, or 0.1 inches.
In certain embodiments, a portion of the pivoting member selectively engages a portion of the transverse member to selectively inhibit the pivoting member from pivoting relative to the transverse member and to selectively inhibit large scale movement of the moving component relative to the cabinet body.
Additionally, in some embodiments, the pivoting member includes an activator mechanism. In such embodiments, one of the transverse member and the activator mechanism includes a recessed area and the other of the activator mechanism and the transverse member includes a first tab that is selectively positioned within the recessed area. Further, in such embodiments, the pivoting member is inhibited from pivoting relative to the transverse member when the first tab is positioned within the recessed area. Moreover, in such embodiments, the pivoting member is allowed to pivot relative to the transverse member between the first position and the second position when the first tab is removed from the recessed area.
In one embodiment, the activator mechanism further includes a second tab that can be manually manipulated to move the activator mechanism between an engaged position wherein the first tab is positioned within the recessed area, and a disengaged position wherein the first tab is removed from the recessed area. Moreover, the pivoting member can further include a face plate having a plate aperture. In such embodiment, the second tab can extend through the plate aperture.
Further, in some embodiments, the moving component includes a component face. In one such embodiment, the pivoting member pivots relative to the transverse member approximately ninety degrees between the first position, wherein the pivoting member is substantially parallel to the component face, and the second position, wherein the pivoting member is substantially perpendicular to the component face.
Additionally, in certain embodiments, the latch assembly further comprises an attachment assembly that is selectively attached to the cabinet body. In such embodiments, the transverse member is adjustably secured to the attachment assembly. Moreover, in one such embodiment, the attachment assembly includes an attacher body that is selectively attached to the cabinet body, and a support pad that is positioned substantially between the attacher body and the cabinet body. Still further, in one embodiment, the latch assembly can also comprise an adjustment assembly that adjusts the position of the transverse member relative to the attachment assembly.
The novel features of this invention, as well as the invention itself, both as to its structure and its operation, will be best understood from the accompanying drawings, taken in conjunction with the accompanying description, in which similar reference characters refer to similar parts, and in which:
As an overview, the latch assemblies 12 provided herein are uniquely designed so that they can be quickly and easily installed on and/or removed from a drawer 16 or door 30C of the cabinet 10 or 100, and the latch assemblies 12 can be used without causing any unnecessary or unwanted damage to the cabinet 10 or 100. Additionally, the latch assemblies 12 inhibit the drawer 16 or door 30C, i.e. the moving component, of the cabinet 10 or 100 from opening slightly when the latch assemblies 12 are in the locked position, thereby inhibiting any potential pinching of fingers of babies and/or young children. Further, the latch assemblies 12 are visible to the opener of the drawer 16 or door 30C. This provides an indication to the opener of the drawer 16 or door 30C that the latch assembly 12 must be unlatched prior to opening.
As shown in
It should be noted that any of the drawers 16A-16D can be equally referred to as the first drawer, the second drawer, the third drawer and/or the fourth drawer. Moreover, any of the latch assemblies 12A-12D can be equally referred to as the first latch assembly, the second latch assembly, the third latch assembly and/or the fourth latch assembly.
The cabinet body 14 includes a cabinet top 18, a cabinet bottom 20, a pair of opposed cabinet sides 22 and a cabinet face 24. The cabinet face 24 receives the drawers 16A-16D and effectively provides a frame around at least a portion of each of the drawers 16A-16D. In this embodiment, the cabinet face 24 (i) extends substantially from the cabinet top 18 to near the cabinet bottom 20 on either side of the drawers 16A-16D; and (ii) extends from one cabinet side 22 to the other cabinet side 22 above the first drawer 16A, between adjacent drawers 16A-16D, and below the fourth drawer 16D. With this design, the latch assembly 12A-12D can selectively engage and/or be operative relative to the top, the bottom or possibly either side of the drawers 16A-16D.
Each drawer 16A-16D includes a drawer body (not illustrated), a drawer face 26, and a handle 28. The drawer body provides a storage area for storing items as desired. When the drawer 16A-16D is closed, as illustrated in
Additionally, as will be illustrated and described in detail herein, the latch assembly 12 is designed so that the latch assembly 12 can be quickly and easily moved from the locked position (as illustrated in
Further, depending on the particular style and/or design of the cabinet 10, the drawer 16 or door 30C may be able to be moved slightly when the latch assembly 12 is in the locked position, e.g., in a cabinet that includes a bevel around the perimeter. However, even with such cabinets, the allowable movement of the drawer 16 or door 30C would be less than the thickness of the drawer 16 or door 30C, thereby substantially reducing the risk of babies or young children slamming fingers between the drawer 16 or door 30C and the cabinet face 24C.
In different embodiments, the latch assembly 12 can be used for inhibiting children from accessing kitchen and bathroom cabinet drawers and doors. However, the latch assembly 12 may also be used in dressers, marine cabinets, and motor home cabinets. For example, in marine cabinets and motor home applications, it is desirable to keep cabinet drawers and doors from opening while underway.
As illustrated, the latch assembly 12 selectively engages the top of the door 30C. Alternatively, the latch assembly 12 can selectively engage the bottom of the door 30C or the latch assembly 12 can possibly selectively engage the side of the door 30C away from the hinges (not illustrated), i.e. toward the handle 28C. Further, as illustrated, the latch assembly 12 is in the locked position, thereby inhibiting the door 30C from being opened e.g., by simply pulling on the handle 28C. In certain alternative embodiments, the door 30C can be designed without a handle 28C, and the door 30C can be opened utilizing another means.
As illustrated in
The design of the latch assembly 12 can be varied to suit the specific requirements of the cabinet 10. In the embodiment illustrated in
The attachment assembly 234 is selectively attached to the cabinet 10, e.g., to the cabinet body 14, to selectively couple the locking assembly 236 to the cabinet 10, e.g., to the cabinet body 14. Additionally, the attachment assembly 234, as described herein, selectively couples the locking assembly 236 to the cabinet body 14 without damaging the visible part of the cabinet body 14.
The design of the attachment assembly 234 can be varied to suit the specific requirements of the latch assembly 12 and/or the cabinet 10. In the embodiment illustrated in
As shown in
In this embodiment, the locking assembly 236 is adjustably secured to the attachment assembly 234. The locking assembly 236 provides the operative portion of the latch assembly 12 so that the latch assembly 12 can be quickly and easily moved between the locked position, as illustrated in
The adjustment assembly 238 adjusts the position of the locking assembly 236 relative to the attachment assembly 234 and, thus, adjusts the position of the locking assembly 236 relative to the drawers 16A, 16B and the cabinet body 14. Additionally, the adjustment assembly 238 adjusts the position of the locking assembly 236 to enable the latch assembly 12 to be used on drawers 16 or doors 30C of different heights relative to the cabinet face 24. More particularly, the adjustment assembly 238 adjusts the position of the locking assembly 236 so that the locking assembly 236 can more effectively maintain the second drawer 16B in a closed position. As shown in
The adjustment assembly 238 enables the latch assembly 12 to be used with a wider range of cabinet styles available on the market, and allows the possibility of mounting the latch assembly 12 on either the top, bottom or side of the particular cabinet drawer 16, or the top, bottom or side of a cabinet door 30C.
As provided above, the attachment assembly 234 selectively couples the locking assembly 236 to the cabinet body 14 (illustrated, for example, in
As illustrated in the embodiment shown in
Referring back to
In different embodiments, different size attacher bodies 340, e.g., clamp bodies, may be required depending on the size of the cabinet 10 or drawers 16A, 16B or door 30C (illustrated in
Further, the attacher adjuster 342, e.g., a screw, is used to maintain the attacher body 340 positioned substantially adjacent to the cabinet body 14, the first drawer 16A and/or the second drawer 16B. More particularly, when the latch assembly 12 is coupled to the cabinet 10, a portion of the attacher body 340 is positioned in contact with and/or substantially adjacent to the front 24F of the cabinet face 24 and a portion of the attacher adjuster 342 is in contact with and/or substantially adjacent to the back 24B of the cabinet face 24.
Again referring to
As shown in

In this embodiment, the transverse member 346 is adjustably secured to and cantilevers substantially perpendicularly away from the attacher body 340. With this design, the transverse member 346 can be selectively coupled to the cabinet 10. Further, when installed, the transverse member 346 is designed to extend substantially along an edge, i.e. along the top, the bottom or possibly a side, of the drawer 16 or door 30C of the cabinet 10. Moreover, in some embodiments, the closer the locking assembly 236 is positioned to the edge of the drawer 16 or door 30C, the higher the force required to cause the latch assembly 12 to malfunction.
As illustrated, the transverse member 346 has a substantially square, flat plate-like design and includes a first end 346F, and an opposed second end 346S. Alternatively, the transverse member 346 can have a different shape and/or a different design.
As shown, the first end 346F of the transverse member 346 is adjustably secured to the attacher body 340.
Additionally, in this embodiment, the pivoting member 348 is pivotally secured to the transverse member 346 and/or the pivoting member 348 is pivotally coupled to the attachment assembly 234. More particularly, in this embodiment, the pivoting member 348 is pivotally secured to the second end 346S of the transverse member 346. Alternatively, the pivoting member 348 can be pivotally secured to a different portion of the transverse member 346.
Further, the pivoting member 348 is adapted to pivot about a pivot pin 350 relative to the transverse member 346 between a first position (as illustrated in
As illustrated and described herein, a portion of the pivoting member 348 selectively engages a portion of the transverse member 346 to selectively inhibit the pivoting member 348 from pivoting relative to the transverse member 346. For example, when the pivoting member 348 is in the first position, a portion of the pivoting member 348 engages a portion of the transverse member 346, and the pivoting member 348 is inhibited from pivoting relative to the transverse member 346. Moreover, when the pivoting member 348 is in the first position, the pivoting member 348 inhibits the drawer 16 or door 30C from other than slight movement relative to the cabinet body 14, i.e. the pivoting member 348 inhibits large scale movement of the drawer 16 or door 30C relative to the cabinet body 14.
Conversely, when the pivoting member 348 is in the second position, the pivoting member 348 is free to pivot relative to the transverse member 346. Moreover, when the pivoting member 348 is in the second position, the pivoting member 348 allows for large scale movement of the drawer 16 or door 30C relative to the cabinet body 14.
It should be noted that the use of the terms “first position” and “second position” is merely for ease of description, and either position can be equally referred to as the first position and/or the second position.
As provided above, the adjustment assembly 238 adjusts the position of the locking assembly 236, e.g., the transverse member 346, relative to the attachment assembly 234. The design of the adjustment assembly 238 can be varied to suit the specific design requirements of the latch assembly 12 and/or the cabinet 10. In this embodiment, the adjuster assembly 238 includes one or more adjuster slots 352, one or more adjuster apertures (not illustrated), and one or more adjuster attachers 354 (illustrated in
The adjuster slots 352 are substantially vertically oriented within the attacher body 340, i.e. when the latch assembly 12 selectively engages the top or bottom of a drawer 16 (illustrated in
In one embodiment, the adjuster slots 352 can enable the latch assembly 12 to exhibit approximately one-half inch of adjustability for the locking assembly 236 relative to the attachment assembly 234. Alternatively, the adjuster slots 352 can be designed to allow the latch assembly to exhibit greater than or less than one-half inch of adjustability for the locking assembly 236 relative to the attachment assembly 234.
The adjuster apertures are adapted to receive and retain the one or more adjuster attachers 354. In one embodiment, the adjuster apertures are positioned at or near the first end 346F of the transverse member 346. Alternatively, the adjuster apertures can be positioned in a different portion of the transverse member 346.
Additionally, as illustrated in
With the specific design as described in detail herein, no holes need to be drilled in the cabinet face 24, the drawer 16 or the door 30C, and no adhesives need to be used for purposes of installation or use of the latch assembly 12. Further, the attachment assembly 234 installs on a drawer 16 or door 30C of the cabinet 10 quickly and easily. Moreover, as noted, the attachment assembly 234 utilizes the soft support pad 356 to protect the cabinet face 24 finish from scratches or dents. Additionally, with this design, the latch assembly 12 can be quickly and easily mounted on and/or removed from a cabinet drawer 16 or door 30C to enable easy use in multiple households as desired.
In this embodiment, the transverse member 346 of the locking assembly 236 includes a recessed area 360 positioned near the second end 346S. The recessed area 360 is adapted to selectively receive and retain a portion of the pivoting member 348 of the locking assembly 236. Alternatively, the pivoting member 348 can include a recessed area that is adapted to selectively receive and retain a portion of the transverse member 346.
Additionally, as illustrated in this embodiment, the pivoting member 348 includes a face plate 362, a back plate 364, one or more plate attachers 366 (illustrated in
As shown in
Additionally, the face plate 362 further includes a plate aperture 374, with a portion of the activator mechanism 368 being adapted to extend through the plate aperture 374.
As illustrated in this embodiment, the activator mechanism 368 includes a mechanism body 376, an end tab 378 and a front tab 380. As illustrated, the mechanism body 376 is somewhat C-shaped and is positioned within the member cavity 372. Alternatively, the mechanism body 376 can have a different design.
The end tab 378 extends away from an end of the mechanism body 376, and is selectively positioned within the recessed area 360 that is positioned near the second end 346S of the transverse member 346. More particularly, as shown in
Further, the front tab 380 cantilevers away from the rest of the mechanism body 376. Moreover, as shown in
As provided above, the one or more resilient members 370 are positioned substantially within the member cavity 372. Additionally, as shown, the one or more resilient members 370 can be positioned between the activator mechanism 368 and the face plate 362 away from the transverse member 346. In one embodiment, the one or more resilient members 370 are biased so as to maintain the end tab 378 positioned within the recessed area 360 of the transverse member 346 absent intentional movement of the front tab 380 of the activator mechanism 368 relative to the face plate 362 within the plate aperture 374. With this design, the latch assembly 12 will be inhibited from inadvertently or unintentionally moving from the locked position to the unlocked position.
Further, in one embodiment, the pivoting member 348 can include two resilient members 370 (only one is illustrated in
When the pivoting member 348 is in the first position and the latch assembly 12 is in the locked position, the face plate 362 of the pivoting member 348 is positioned in front of a portion of one of the drawers 16 or the door 30C, e.g., is substantially parallel to the drawer face 26 (illustrated in
In one embodiment, at least a portion of the pivoting member 348 can be made of a softer material to protect the finish of the drawer 16 or door 30C of the cabinet 10 from scratches or dents.
In moving the pivoting member 348 from the first position, as illustrated in
Further, when the pivoting member 348 is in the second position and the latch assembly 12 is in the unlocked configuration, the face plate 362 of the pivoting member 348 is positioned co-extensive with and/or parallel to the transverse member 346, and the face plate 362 is substantially perpendicular to the drawer face 26 (illustrated in
When returning the pivoting member 348 to the first position, the pivoting member is rotated relative to the transverse member 346. During this process, at some point before the pivoting member 348 has been rotated fully back so that the pivoting member 348 is again substantially perpendicular to the transverse member 346, the resilient members 370 will cause the pivoting member 348 to continue rotating so that the activator mechanism 368 is again in the engaged position, the pivoting member 348 is again in the first position, and the latch assembly 12 is again in the locked position. Alternatively, the locking assembly 236 can be designed without the resilient members 370, and the front tab 380 can thus require manual manipulation to return the activator mechanism 368 to the engaged position where the end tab 378 is again positioned within the recessed area 360 of the transverse member 346.
As illustrated, the second front tab 682 extends slightly into the plate aperture 674 near an end or side of the plate aperture 674 opposite the position of the front tab 680 when the activator mechanism 668 is in the engaged position. Prior to moving the activator mechanism 668 from the engaged position to the disengaged position, the activator mechanism 668 must be pushed in slightly, against the force of the second resilient member (not illustrated), so that the second front tab 682 no longer extends slightly into the plate aperture 674. Alternatively, the activator mechanism 668 can be designed without the second resilient member and the second front tab 682 can be allowed to flex slightly inwardly relative to the mechanism body 676, so that the second front tab 682 no longer extends slightly into the plate aperture 674.
Subsequently, when the second front tab 682 has been removed from the plate aperture 674, the activator mechanism 668 can then be moved translationally, as with the previous embodiments, from the engaged position to the disengaged position. Then, with the activator mechanism 668 in the disengaged position, i.e. with the end tab 678 no longer positioned within the recessed area 660 of the transverse member 646, the pivoting member 648 can be pivoted relative to the transverse member 646 from the first position to the second position. Stated another way, with the activator mechanism 668 in the disengaged position, the latch assembly 612 can quickly and easily be moved to the unlocked position.
Further, as illustrated in this embodiment, the mechanism body 776 of the activator mechanism 768 can be somewhat rectangle shaped. Alternatively, the mechanism body 776 can have a different shape.
It should be noted that the specific designs and features of the latch assemblies as illustrated herein can be combined or omitted as desired, and additional features can be added, to allow for greater design flexibility.
In step 801, the drawer or door of the cabinet is opened. This provides the necessary access to the portion of the cabinet face that is positioned adjacent to the drawer or door onto which the latch assembly is to be installed. Additionally, adjacent drawers or doors can also be opened, if necessary, to provide better access to the cabinet face.
In step 803, the attacher body of the attachment assembly is positioned about the cabinet face adjacent to the drawer or door onto which the latch assembly is to be installed. Further, in step 805, the position of the locking assembly relative to the attachment assembly can be set or adjusted, as necessary, with the adjustment assembly. In one embodiment, the locking assembly is adjusted so that the transverse member will be positioned as close as reasonably possible to the edge, i.e. the top, bottom or side, of the drawer or door onto which the latch assembly is to be installed.
Additionally, in step 807, the attacher adjuster is tightened so that the latch assembly is effectively coupled to the cabinet face. Further, in step 809, one should ensure that the latch assembly is in the unlocked position, with the pivoting member of the locking assembly being in the second position relative to the transverse member.
Still further, in step 811, the drawer or door onto which the latch assembly is being installed is closed. Then, in step 813, the pivoting member is pivoted relative to the transverse member so that the pivoting member is in the first position, and the latch assembly is in the locked position.
