Abstract
A latch mechanism for tool cabinets, for releasably holding a tool cabinet drawer in a closed position within a tool cabinet housing, comprising a handle for fixed installation about a front panel of the tool cabinet drawer. A latch release bar is movably attached to either one of the drawer front panel and the handle such that the latch release bar is installed in the vicinity of the handle, the release bar being movable between a rest position and a released position. A first retaining member, attached to the tool cabinet housing, cooperates with a second retaining member operatively connected to the latch release bar, wherein when the latch release bar is moved in its rest position, the second retaining member is moved in a first position, for releasable connection to the first retaining member when the drawer is in its closed position, and wherein when the latch release bar is moved in its released position, the second retaining member is moved in a second position, for disconnecting the first retaining member from the second retaining member when the drawer is in its closed position.
Description
- The present invention relates to latch mechanisms, and more particularly to a latch mechanism for holding drawers of a tool cabinet in a closed position.
- Tool cabinets generally include a housing and a vertical row of drawers, each drawer being slidable in and out of the cabinet housing between closed and opened limit positions. Certain varieties of tool cabinets have a number of casters mounted to the bottom surface of their housing, and can roll over ground in order to be moved around easily in the workshop.
- When a tool cabinet is being rolled around in the workshop, it can happen that the drawers open—i.e. extend outwardly—accidentally. This can be hazardous as drawers opening suddenly can hit and injure a workman, and can destabilize the cabinet. Indeed, the drawers generally contain heavy tools, and sudden opening of drawers, especially upper drawers of the cabinet, causes the weight of the heavy tools to shift horizontally away from the cabinet main frame, so as to act as a cantilever weight which can lead the cabinet to lose its balance and tip over.
- It is therefore desirable to provide the drawers of ground-standing rollable tool cabinets with a releasable latch mechanism to hold them in a closed retracted position. Latch-provided drawers cannot be pulled out and opened unless the latch mechanism is released thus obviating spontaneous opening of the drawers under momentum-based gravitation-borne forces when the cabinet is rolled over ground.
- Various types of latch mechanisms for tool cabinet drawers have been devised in the past, but are awkward to manipulate and include a high number of small cooperating parts, which lessens their reliability.

bottom portion 32 a extending upwardly from the top edge ofmain plate portion 29 with a rearward slant; - a
rear portion 32 b extending vertically upwardly from the rear edge ofbottom portion 32 a; - a
top portion 32 c extending horizontally from the top edge ofrear portion 32 b, and frontwardly beyond the vertical plane ofmain plate portion 29; - a
gripping lip 32 d extending frontwardly with a downward slant from the front edge oftop portion 32 c, away frommain plate portion 29.
- a
- Moreover, two
support tabs 34 are provided onhandle 32 in the vicinity oflateral edges front panel 28. Eachtab 34 consists in a partially cutout piece of handlerear portion 32 a bent frontwardly upwardly until itsfree end 34 a abuts against the undersurface oftop portion 32 c, as can be seen in the side views ofFIGS. 5-6 . -
Drawer 20 further comprises alatch mechanism 40 according to the present invention.Latch mechanism 40 comprises an elongatedlatch release bar 42 pivotally mounted tofront panel 28 and extending lengthwisely betweenlateral edges handle top portion 32 c and grippinglip 32 d.Latch release bar 42, in the present embodiment, is made of single sheet-like metal plate suitably bent into shape.Latch release bar 42 integrally comprises amain portion 42 a, from the rear edge of which upwardly extends, with a frontward slant, astopper flange 42 b.Main portion 42 a andstopper flange 42 b intersect at astraight pivot ridge 45. Atrigger tongue 42 c extends frontwardly from the front edge ofmain portion 42 a, with a downward slant. Thefree end portion 42 d oftrigger tongue 42 c is folded over, in order to double its thickness and weight. - Two
openings 43 are made through latch release barmain body 42 a. Theseopenings 43 inlatch release bar 42 are penetrated by corresponding and registeringsupport tabs 34 ofhandle 32, andlatch release bar 42 is thereby mounted tofront panel 28. Thepivot ridge 45 oflatch release bar 42 bears against the trough of the wedge-shaped space 35 (FIGS. 5-6 ) formed in combination bysupport tabs 34 and handlerear portion 34 b. -
Latch mechanism 40 is further provided with a pair of male retaining means, in the form of plate-like, hook-shapedcatch members 50.Catch members 50 each define an elongatedmain body 50 a, and anattachment tab 50 b extending from one end ofmain body 50 a transversely thereto.Attachment portions 50 b are fixed to opposite ends of elongatedlatch release bar 42 on themain portion 42 a thereof. A generally triangular retainingportion 50 c is provided on the end ofmain body 50 aopposite attachment tabs 50 b, and defines a roundedtip 50 d and a slanted slidingedge 50 e. - The assembly of
latch release bar 42 and catchmembers 50 is pivotable relative tofront panel 28 about thepivot ridge 45 oflatch release bar 42. At rest, thelatch release bar 42 is in a rest position wherestopper flange 42 b abuts against therear surface 34 b of eachsupport tab 34. In this rest position oflatch release bar 42,catch member 50 is in a raised limit position. By applying upward pressure with his hand H ontrigger tongue 42 c oflatch release bar 42, an operator, as suggested inFIG. 5 , can releaselatch bar 42 and catchmembers 50 can be pivoted in a clockwise direction with respect to the viewpoint ofFIGS. 5-6 sequentially aboutpivot ridge 45. Pivoting oflatch release bar 42 is only possible over a limited angular spread, as during its pivoting course towards its released position, latchrelease bar tongue 42 c eventually comes in abutting contact with the undersurface ofhandle 32, and is blocked from further pivoting. Such pivoting oflatch release bar 42 induces the downward displacement of retainingportion 50 c towards a lowered limit position. Upon release of the upward pressure applied on latch releasebar trigger tongue 42 c, thelatch release bar 42 returns to its rest position and catchmember 50 returns to its raised limit position. This is chiefly due to the fact that thefree end portion 42 d of latch releasebar trigger tongue 42 c forms a weight, since it is folded over and its weight is thereby doubled, allowing gravity to continuously bias thelatch release bar 42/catch members 50 assembly in a counter-clockwise pivotal direction (with respect to the viewpoint ofFIGS. 5-6 ). It is understood that alternate passive biasing means such as other weight-increasing means could be used to continuously biaslatch release bar 42 towards a rest position and catchmember 50 in a raised limit position. - Although the above-described pivotal mounting means of the
latch release bar 42/catch member 50 assembly onfront panel 28 have proven to be very reliable, the pivotal mount of this assembly aboutfront panel 28 could be achieved in any other way known in the art. For example,latch release bar 42 could be alternately hinged tofront panel 28. -
Drawer 20 is movably mounted tocabinet housing 12 through the instrumentality of conventional telescopic carriage slides 60, eachtelescopic slide 60 comprising threeslide segments Outer slide segment 62, which is cross-sectionally U-shaped as illustrated inFIG. 4 , is lengthwisely secured in a horizontal position to the inner surface of theside walls cabinet housing 12, and theinner slide segment 66 is lengthwisely secured horizontally to the outer surface ofside walls drawer 20.Intermediate slide segment 64 is suitably rollably mounted to both inner andouter slide segments Outer slide segment 62 is stationary relative tohousing 12, andintermediate slide segment 64, through its rollable interconnection with both inner andouter slide segments inner slide segment 66 relative to stationaryouter slide segment 62, in order fordrawer 20 to be axially slidable in and out ofcabinet housing 12 through opening 14. -
Latch mechanism 40 is further provided with female retaining means in the form ofapertures 68 made in the upper front end portion of cross-sectionallyU-shaped slide segment 62 for cooperation with the male retaining means, i.e.catch member 50. The relative alignment ofdrawer 20 intocabinet housing 12 is such that whendrawer 20 is in its closed (retracted) position, catchmember retaining portion 50 c registers vertically beneathaperture 68. Whenlatch release bar 42 is at rest,catch member 50 is in its raised limit position and its retainingportion 50 c is interlocked inaperture 68. - In alternate embodiments, other female retaining means could be provided instead of
apertures 68, such as strikes independent from the telescopic slides secured to the cabinet housing, for cooperation with the male retaining means of the latch mechanism. - Use of the present invention will now be described. When the
drawer 20 is closed, i.e. is fully retracted withincabinet housing 12 as shown inFIG. 1 , both catchmember retaining portions 50 c of thelatch mechanism 40 are interlocked in correspondingapertures 68 of telescopic slides 60. This interlocking engagement holds thedrawer 20 in their closed position. Accordingly, whendrawers 20 are closed and thelatch release bar 42 is at rest,latch mechanism 40 ensures thatdrawers 20 remain closed, and thetool cabinet 10 can be rolled around the workshop without fearing that thedrawers 20 open spontaneously under momentum-borne forces. - To open a
drawer 20, the user, while resting his thumb overhandle 32 as suggested inFIG. 5 , uses his other fingers to apply upward pressure onlatch release bar 42. This pivots thelatch release bar 42/catch member 50 assembly in a clockwise direction (with respect to the viewpoint ofFIG. 5-6 ) aboutpivot ridge 45, which causes catchmember retaining portion 50 c to be lowered and egress out ofaperture 68. When catchmember retaining portion 50 c clearsaperture 68,drawer 20 is no longer prevented from opening and the user can thus slidably pull the drawer out ofhousing 12 with his hand H to gain access to itsinner compartment 21 where tools or other items may be stored. - To close the
drawer 20, the user can apply an upward pressure onlatch release bar 42 while pushing the drawer back towards its closed position. When the drawer is closed, thelatch release bar 42 can be released, thereby reestablishing the interlocking engagement between catchmember retaining portion 50 c andaperture 68. Alternately,drawer 20 can simply be pushed back in its closed position without pushing thelatch release bar 42 in its released position. As the drawer approaches its closed position, therounded edge 50 d and slanted slidingedge 50 e of catchmember retaining portion 50 c strike and slide on the front edge ofouter slide segment 62 and catchmember 50 is slidably pushed downwardly until its retainingportion 50 c registers vertically underneathaperture 68. Thelatch release bar 42/catch member 50 assembly then automatically moves in a counter-clockwise direction (with respect to the viewpoint ofFIGS. 5-6 ) under the influence of gravity as described hereinabove,catch member 50 returns to its raised limit position, and retainingportion 50 c penetrates intoaperture 68 to return into interlocking engagement therewith. - The embodiments described in the foregoing description provide for a drawer mounted to a cabinet housing through the instrumentality of telescopic slides, with the female retaining member of
latch mechanism 40 being anaperture 68 made into the outer segment of the telescopic slides. It is understood that in alternate embodiments of the present invention, any suitable means could be provided to allowdrawers 20 to be axially moved in and out of the tool cabinet housing instead of telescopic slides. Moreover, any suitable retaining means other than thecatch member 50/aperture 68 combination could be used as detent means to hold the drawer of the tool cabinet in its closed position, as long as actuation of a latch release bar causes release of the detent means to permit opening of the drawer. - The fact that a movable latch release bar located beneath a fixed handle must be actuated to release the latch mechanism of the present invention, is a maneuverability improvement over similar prior art latch-provided tool cabinets.
- Some prior art tool cabinets have drawers having a front panel to which is mounted a handle, these drawers being held in a closed position by a latch mechanism. The front handle of each drawer is pivotable relative to the front panel, and is operatively linked to the latch mechanism. Accordingly, to open a drawer, a user must grip the handle, twist it in order to pivot it into a released position, thereby disengaging the latch mechanism, and can then pull the drawer by the same handle to slide it out of the tool cabinet into an open position. Such prior art latch mechanism are impractical and awkward to use, since no fixed and steady grip is provided on the drawer. When a user grips the twistable handle without wanting to disengage the latch mechanism but only to move the drawer between open and closed positions, the handle is likely to unsteadily jolt between its rest and released positions.
- With the present invention, the user can maintain a firm and steady grip on a fixed handle while using his other fingers to actuate the movable latch release bar, which makes the latch mechanism less awkward to use and more user-friendly.
- Moreover, the present invention has proven to be surprisingly resistant to wear. Indeed, as can be inferred from the foregoing description and observed in the drawings, the latch mechanism comprises a small number of cooperating parts, and is thus very reliable. In particular, the latch release bar is biased towards its rest position by passive biasing means, i.e. by the provision of weights thereon to allow it to be naturally gravity-biased towards its rest position, and obviates use of dynamic biasing means such as springs in order to return to its rest position. This imparts increased reliability to the latch mechanism of the present invention, since even wear of its components is unlikely to cause it to stop functioning. On the other hand, prior art spring-provided latch mechanisms are much more vulnerable to wear since springs are known to lose their resiliency with age. When the spring of a prior art latch mechanism of a given tool cabinet drawer loses its resiliency, the latch release bar can no longer automatically recoil to its rest position once it has been actuated in its released position, and the latch mechanism can no longer return to its locked condition to hold the drawer in a closed position, which defeats the purpose of the present invention.
