- ABSTRACT A progressive, full ball bearing, precision, telescoping 1 51 Aug. 26, 1975 slide mechanism for the suspension of drawers having an adaptor attached to the drawer to provide simple attachment without tools to the drawer and to permit the drawer to be easily without tools removed from the slide when it is desired to do so, and readily reinserted, or interchanged with other drawers.
- an adaptor attached to the drawer to provide simple attachment without tools to the drawer and to permit the drawer to be easily without tools removed from the slide when it is desired to do so, and readily reinserted, or interchanged with other drawers.
- the latching mechanism in one arrangement is manually operated.
- the latching mechanism latches automatically.
- Another feature is a combination of stops which will absorb any metal clicking noise at times of opening or closing of drawer, thus, contributing to the elimination of todays harmful noise pollution modern office ecology is exposed
- Still another feature comprises means to hold a drawer in the closed position so that a slight forward tilt of the drawer or cabinet will not let the drawer come out as the slides roll very easily. Also, a too forcefully closed drawer has a tendency to come out against, that is, to bounce open. With the present invention, these conditions are overcome.
- Our invention comprises mounting means and functional ball bearing slide features which include in their combinations, become a part of the precision telescoping ball bearing slides.
- This permits ready attachment of the drawers to the slides so that the drawers may be reinserted or interchanged with other drawers.
- the invention also eliminates what in offices is called today noise pollution caused by the noise and metallic clicking when drawers are moved back and forth in such units as file drawers, desk drawers, department store fixture drawers, etc. Thus it contributes greatly to the improvement of office ecology.
- a sound muffling material is employed and is positioned so that metal to metal contacts are eliminated.
- the latch mechanism part which drops into a notch provided therefor in the outer slide member, automatically locking the drawer to the slides, prevents any noise or clicking when the moving drawer comes to a stop, either in the open position or the closed position.
- the latch or resilient material or block automatically and releasably locks the drawer to the slide without creating any noise when the drawer is moving.
- a precision, ball bearing slide is a linkage connecting a stationary structure with a moving structure, both being connected to this slide.
- the invention covers the following areas of telescoping, ball bearing, precision drawer slides:
- This adaptor comprises a mounting rail which is mounted on or attached to the drawer or other moving object;
- a locking latch on the adaptors for positively but releasably locking the adaptor to the outer members of the slides.
- the locking or latching mechanism locks or latches automatically;
- the invention also eliminates what in offices is called noise pollution caused by the noise and metallic clicking when drawers are moved back and forth in such units as file drawers, desk drawers, department store fixture drawers, etc. Thus, it contributes greatly to the improvement of office ecology;
- Two holes are extruded upwardly from the rail to provide securing means for the spring latch which has two latching holes aligned with the extruded holes.
- the extruded set-ups are then knurled over the spring latch surface thereby fastening it or securing it to the rail.
- a hold-in detent is holding the drawer in position when closed so that any slide forward tilt of the desk, cabinet or the like, will not let the drawer come out. Also, this hold-in detent arrangement, will prevent the drawer to come out when it is too forcefully closed.
- the slide mechanism also includes provision whereby it is reversible, that is, it can be attached to either side of the drawer. Thus, it is not necessary to make right and left-hand mechanisms thereby reducing manufacturing costs.

- FIGS. 1 5 there is shown one embodiment of a slide mechanism embodying the present invention and indicated generally at 24.
- the mechanism includes the usual outer slide member indicated generally at 28 and an inner slide member, not shown, in FIGS. 1 5, but shown and described hereandafter.
- FIG. 1 there is shown a desk or cabinet 30 having a drawer 32, it being understood, of course. that there may be more than one drawer, the inner slide member in this figure being hidden from view since it is fastened to an adjacent part of the desk or cabinet.
- each side of the drawer there is a slide mechanism for each side of the drawer. As shown in FIG. 1, the drawer is in an outward or open position. The outer slide members of the slides at opposite sides of the drawer are free to slide into and out of the cabinet 30.
- the outer slide member 28, FIG. 1, is shown to be in its extended position and it should be noted that the outer slide element is not affixed to the drawer side wall 34.
- the means for attaching the desk drawer to the slides comprises an adaptor or drawer attachment, indicated generally at 36, which in cross-section, is shaped like a Z lying on its side. That is, there is a horizontal portion 38, a vertical upstanding portion or flange 40 along one longitudinal edge of the horizontal portion, and a depending portion or flange 42 along the opposite longitudinal edge.
- the longitudinally extending vertical portion or flange 40 has a plurality of longitudinally spaced openings for screws 44 for attaching the adaptor 36 to side 46, FIG. 1, of the drawer 32.
- the longitudinally extending horizontal portion 38 has a locking clamp, indicated generally at 48.
- the locking clamp 48 comprise a lever 50 pivotly attached to the horizontal part 38, sometimes termed the rail, by any suitable means such as a rivet 54 adjacent one end so as to be freely movable in a horizontal plane.
- an upstanding ear 56 Adjacent the opposite end is an upstanding ear 56 so that the lever may be easily actuated between locking and release position.
- lever 50 Adjacent the opposite end is an upstanding ear 56 so that the lever may be easily actuated between locking and release position.
- lever 50 there is a flange 60 depending at right angles from the outer edge of the lever and at the lower end of flange 60, is an inturned lip 62 normal to said flange 60.
- the locking lip 62 of the locking clamp 48 fits under and engages the free edge 64 of the outer slide member 28.
- the locking clamp 48 now vertically locks together the adaptor 36 and the outer slide element 28, the engagement of the horizontal part 38 of the rail and the top of the outer slide member 28 effects secure locking together of the adaptor and the outer slide member.
- latch 48 is manually actuated by means of the upstanding ear 56 to the release position shown in FIG. 3.
- a locking block 68 which is affixed to the under side of the lever 50 by means of a rivet 70 although any other suitable fastening means may be used.
- the locking block 68 is adapted to fit into a locking slot 72 in the upper portion of the outer slide element 28. More specifically, slot 72 is in the upper ball race 74 of said outer slide member.
- the locking block 68 may be formed of any suitable material, it has been found preferable to use a resilient material such as rubber, urethane or the like.
- the locking block 68 has a fairly snug fit in the locking slot 72 of the outer slide element but a limited amount of longitudinal movement may occur and the resilient material is sound absorbing or muffling to substantially eliminate noise.
- the drawer 32 is illustrated with its inner end positioned within the cabinet 30 and with the adaptor 36 resting on the top of the outer slide element 28.
- the locking clamps are open and the drawer is lowered onto the slide member 28, the lower surface of the horizontal part 38 of the adaptor coming to rest on the top of the outer slide element 28 so that the slide thus supports the weight of the drawer and its contents.
- the locking block 68 of the locking clamp 48 enters the locking slot 72 of the outer slide element 28 when the locking clamp is moved to the closed position.
- the drawer may be pushed into or pulled outwardly of the cabinet, the longitudinal locking arrangement between the locking block and the locking slot assure that the slide mechanism operates as designed, and also assures that the drawer may be easily removed by unlocking the locking clamp and lifting the drawer from he sides whenever so desired.
- the horizontal portion 38 of the adaptor floats or slightly rests on the curved top portion of the top races 74 of the outer slide members 28.
- the depending flanges 42 of the adaptors depend along side the free edges of said top races of the outer slide member to thereby aid in retaining the drawer in proper alignment with the slides.
- the outer slide members 28 of the respective slides first move outwardly to their limit of movement.
- the adaptors remain at the position on the top races of the outer slide members, but, when the outer slide members are stopped, the drawer may be further pulled out with the adaptors sliding on said top races of the outer slide members of the slides at opposite sides of the drawer by releasing the locking clamps, the drawers thus being released and adapted to be pulled to the fully extending position whereat the rear end of the drawer is clear or substantially clear of the desk at the drawer opening.
- the drawer may be easily and quickly removed from the slides of the desk or cabinet and easily and quickly replaced. Further, it will be apparent that a drawer may be removed and replaced by another drawer.
- the slides are also practically noiseless and extremely smooth in action. Opening and closing the drawers is practically effortless requiring but a light touch. Removal and replacement of drawers may be effected quickly and easily.
- the outer slide member may be provided with a similar notch 72 in the'lower ball race.
- the slides may be reversed. That is, the slides may be attached at either side without otherwise being specially constructed for such an arrangement.
- FIGS. 8, 9, 10 AND 11 Referring to FIGS. 8, 9, 10 and 11, there is shown an alternative adaptor and slide arrangement.
- the slide mechanism includes the outer slide member 28 of the ususal well-known character and an inner slide member 80, there being a ball retainer indicated generally at 82 which retains the ball bearings 83 and spaces them apart in the ball races of the inner and outer slide member.
- the upper ball race of the outer slide member is provided with a pair of notches 84 and 86, separated by-dividing part 87, notch 84 being of greater size than notch 86 and being closer to the end of the slide.
- Notch 86 is actually a rearward extension of notch 84 and connects with the rear of notch 84.
- Adjacent its inner end, the outer slide member Adjacent its inner end, the outer slide member has a raised tab 88 lanced from the upper ball race thereof and opening forwardly.
- the slide member is attached within the inner desk opening or other fixed part, while the outer slide member carries the drawer as will be here and after fully described.
- the inner slide member has resilient parts 92 and 94 whereby said inner slide member is attached to the desk, cabinet or the like.
- the outer slide member is provided with ridges in the bottom thereof and in the region of the openings 84 and 86 to thereby strengthen this part of the outer slide member.
- Adaptor 96 comprises what is termed herein a rail 98 of generally in the shape of a Z lying on its side. There is a horizontal part 100 along one edge, the rail has an upstanding or vertical flange 102 and along the opposite edge, there is a depending flange 104. Horizontal part of the rail is adapted to normally rest upon the upper ball race of the outer slide member. The rail may also slide upon the upper ball race under certain conditions described hereandafter.
- Flange 102 is secured to the side of the drawer by means of screws 106 or by any other suitable means.
- a down-turned and slightly in -turned guide and connector Adjacent the forward end of the adaptor rail is a down-turned and slightly in -turned guide and connector which is in the general shape of a U lying on its side and indicated generally at 135, the purpose of which will be described hereandafter.
- the releasable clamping mechanism comprises a latch or locking arrangement comprising an elongated resilient spring 108.
- Spring 108 normally lies on the horizontal part 100 of the rail and the rear end of said spring is secured to said horizontal part of the rail by a unique fastening means comprising upward extrusions 110 from the horizontal part of the rail so that the under surface of the horizontal part 100 of the rail is smooth.
- a unique fastening means comprising upward extrusions 110 from the horizontal part of the rail so that the under surface of the horizontal part 100 of the rail is smooth.
- There are two holes in the spring latch 108 through which the extrusions 110 extend and are riveted over at their ends 112 thereby securing the spring latch to the horizontal part of the rail.
- a hole 114 is also provided in the horizontal part of the rail intermediate the extrusions 110 and a dimple 116 formed downwardly in the spring latch, extends into hole 114 and does not extend below the lower plane of the spring latch. This provides a very effective lock so that the spring latch does not create any shear forces upon the two extruded parts since the dimple thus takes any side shear forces. These shear forces are applicable when the latch drops into the slot of the outer member preventing the drawer from moving backward and forward or being disconnected.
- the holder for this material comprises a pair of depending ears 122 spaced apart and having inturned end portions 124 which extend beneath the piece of material 120.
- the piece of material 120 is clamped between the inturned portions 124 and the adjacent part of the spring latch.
- a downwardly and forwardly inclined tongue 126 which functions as a cam, and is lanced from the spring latch and normally rests in the notch extension 86 as best shown in FIGS. 8 and 9.
- Spring latch 108 has an upturned flange-like structure 127 which is at the side adjacent the upturned flange 102.
- This structure has an opening therein with a vertical part 128 adapted to be slidingly received in the space between an ear 130 lanced from the vertical part 102 of the rail and spaced outwardly a sufficient distance to slidingly receive the vertical part 128.
- Structure 127 has a laterally turned flange 132 which is adapted to be engaged by the thumb or other digit of the operator and an outwardly turned stop 134 is lanced laterally from the vertical flange 102. Stop 134 is spaced upwardly of the spring latch a sufficient distance to permit the free end of the latch to be raised to clear the material 120 and the tongue 126 from the openings 84 and 86 thereby releasing the adaptor from the outer slide member.
- the drawer With the adaptors attached to the respective sides of a drawer, the drawer is placed on the slide members with the horizontal part of the rail of the adaptor resting on the upper ball races of the outer slide members.
- the muffling material or block 120 and the tongue or cam 124 rests on the horizontal part of the rail forwardly of notches 84 and 86 and is forced upwardly against the spring tension of spring latch due to the weight of the drawer.
- the drawer is then slid rearwardly and, as this is done, the outer end of the upper ball race, which is slightly notched along the free edge, slides into the guide and connector 135 thereby interconnecting the front end of the adaptor and the front end of the outer slide member.
- Still further rearward movement of the drawer causes the free end of the cam 126 to drop into the opening 86 of the upper ball race of the outer slide member and simultaneously allows the block or muffling material to drop into the opening 84, thus, preventing linear or longitudinal movement of the adaptor and outer slide element.
- the structure 127 is held against lateral displacement by the ear 130.
- the forward free end of the spring latch is raised by means of the flange 132 to a position whereat said spring latch engages the stop 134 thus clearing the block 120 and the cam 126 with respect to the upper ball race of the outer slide member.
- the drawer then may be moved forwardly to disengage the forward ends of the adaptor and outer slide member as well as the rear ends of these parts.
- the drawer may then be lifted from the slides and removed.
- Replacing of the drawer is effected by placing it on the slide mechanisms with the horizontal part 100 of the rail of the adaptor resting on the upper ball race of the outer slide members. Securing the adaptors and outer slide members together is effected as above described.
- Laterally-turned flange 138 provides a stop at the rear part of the slide mechanism and there is a block 140 which serves as a bumper and sound muffler.
- This block is attached to the central part 142 of the ball retainer, said bumper projecting longitudinally outwardly of the ball retainer and clamped onto said central part 142 by means of a shallow channel-shaped bracket 144 which is attached to the central part of the ball retainer by means of a rivet 146.
- a similar bumper is similarly attached to the opposite end of the ball retainer.
- FIGS. 14 17 INCLUSIVE In one type of slide mechanism, there is an intermediate member indicated generally at 200, having a horizontal part 202 with upwardly and downwardly extending flanges 204 and 206. This member has a notch or opening 208 intermediate its ends and there is a roller 210 of resilient material such as rubber, plastic or the like carried on a rivet 212 or the like.
- the rivet may be of any suitable type and extends through openings provided therefor in ears 214 extending downwardly and upwardly from the respective flanges 204 and 206.
- slide mechanisms While the slide mechanisms are held against extension by the bosses, said slide mechanisms may be extended by a force sufficient to overcome the holding of the roller between the bosses. Since the roller is of resilient material, it does not require a great deal of force to release the slide mechanisms to permit their extension.
- This arrangement is for the purpose of releasably holding the drawer or the like supported by the slides in the closed position so that the drawer will not slide open should the cabinet, desk or the like be slidably inclined in a direction that would otherwise cause the drawer to slide open. Also, this arrangement, prevents the drawer from snapping or bumping out when it is closed.
- the bottom wall 220 is provided with a pressed-out portion indicated generally at 222.
- This portion has a part 224 inclined laterally and toward the adjacent end of the slide member.
- a part 226 which is curved toward the adjacent wall of the slide member to provide a hump 228.
- the other slide member 230 is provided with a frictional button of a suitable plastic, such as, for example, nylon, teflon or the like. This button is secured to the bottom of the slide member 230 by means of a rivet 234 or any other suitable means.
- the free end of the buttom is rounded and is adapted to be at the outer side of the hump 228 when the slide members are telescoped and thus, hold the slide members in the telescoped position under normal conditions.
- a sufficient force may be readily applied to cause the button to ride over the hump 228 and thus release the slide members for normal extension.
- Both of these arrangements serve the same purpose of holding the slide members in a telescoped position so that the drawer carried by the slides, will not inadvertently slide open.
- the resistance of the parts holding the slide members telescoped is not great and the drawer may be readily pulled open.
- slide mechanisms which have means for removably mounting drawer slides and latching or locking drawers on the slides.
- the mounting means comprise adaptors attached to the sides of a drawer and the latching or locking means for securing the adaptors and the slide mechanisms together, hold the adaptors from being lifted from the slide mechanisms and also hold the adaptors from sliding on the slide mechanisms when the latching means are in the latching or locking position.
- the slide mechanisms may all be formed the same and a mirror reversal of the slide mechanisms make it possible to use these same slide mechanisms for either side of the drawer.
- a further feature of the present invention includes hold-in stops which hold the drawer in position when closed so that any slide forward tilt of the desk, cabinet or the like will not let the drawer come out. Also, holdin stops or detents, prevent the drawer from bumping out when it is too forcefully closed.
- a drawer slide mechanism comprising:
- an outer slide member having facing ball races along the longitudinal side edges thereof;
- an inner slide member having oppositely facing ball races along the longitudinal side edges thereof, the ball races of the inner slide member being spaced inwardly from and facing respective adjacent ball races of the outer slide member to provide operable space for balls;
- a generally channel-shaped ball bearing retainer disposed between the outer and inner slide members, said ball bearing retainer having flanges at the outer longitudinal edges between adjacent ball races of the outer and inner slide members, said flanges having openings for the balls, said openings being of smaller size than the diameter of the the inner slide member being spaced inwardly from and facing respective adjacent ball races of the outer slide member to provide operable space for balls;
- a generally channel-shaped ball bearing retainer disposed between the outer and inner slide members, said ball bearing retainer having flanges at the outer longitudinal edges between adjacent ball races of the outer and inner slide members, said flanges having openings for the balls, said openings being of smaller size than the diameter of the balls so said balls are held in the races of the outer slide member by the flanges of said ball bearing retainer;
- a drawer mounting adaptor adapted to be attached to the side of a drawer and resting on the top of the outer slide member of a slide mechanism
- a drawer mounting adaptor adapted to be attached to the side of a drawer and resting on the top of the outer slide member of a slide mechanism

ADAPTOR AND LATCHING MEANS FOR REMOVABLY ATTACIIING DRAWERS TO TELESCOPING BALL BEARING DRAWER SLIDES CROSS-REFERENCE TO RELATED APPLICATION This application, a Continuation-in-part of: Magnus F, Hagen and Fred A. Jordan For: PRECISION TELE- SCOPING BALL BEARING DRAWER SLIDE SUS- PENSION FOR WOOD AND METAL FURNITURE PRODUCTION Ser. No: 396,593 Filed: Sept. 12, 1973, now abandoned BACKGROUND OF THE INVENTION I. Field of the Invention While the invention has particular utility embodied in slides for drawers of wood and metal furniture, file cabinets, desks, cabinets and the like, and is shown and described thus embodied, it is to be understood that its utility is not confined, thereto.
2. Description of the Prior Art There are various types of drawer slides in the prior art of which we are aware having means for removal and replacement of drawers from their slides, but as far as we are aware, these are not satisfactory for various known reasons.
SUMMARY OF THE INVENTION Our invention comprises mounting means and functional ball bearing slide features which include in their combinations, become a part of the precision telescoping ball bearing slides. There is an adaptor attached to the drawer to provide means whereby a drawer may be easily attached to the slides without the use of tools and may be easily removed from the slides when it is desired to do so. This permits ready attachment of the drawers to the slides so that the drawers may be reinserted or interchanged with other drawers. At the same time, the invention also eliminates what in offices is called today noise pollution caused by the noise and metallic clicking when drawers are moved back and forth in such units as file drawers, desk drawers, department store fixture drawers, etc. Thus it contributes greatly to the improvement of office ecology.
In this connection, a sound muffling material is employed and is positioned so that metal to metal contacts are eliminated. The latch mechanism part which drops into a notch provided therefor in the outer slide member, automatically locking the drawer to the slides, prevents any noise or clicking when the moving drawer comes to a stop, either in the open position or the closed position. Thus, the latch or resilient material or block automatically and releasably locks the drawer to the slide without creating any noise when the drawer is moving.
It should be stated that in order to understand the importance of the invention that a precision, ball bearing slide is a linkage connecting a stationary structure with a moving structure, both being connected to this slide.
The invention covers the following areas of telescoping, ball bearing, precision drawer slides:
An adaptor attached to a drawer or the like for providing easy and quick removal of the drawers from the desk, cabinet or the like and easy and quick replacement thereof without the use of tools. This adaptor comprises a mounting rail which is mounted on or attached to the drawer or other moving object;
A locking latch on the adaptors for positively but releasably locking the adaptor to the outer members of the slides. In one arrangement, the locking or latching mechanism locks or latches automatically;
In the automatic latching arrangement, there is a spring for moving the latch to the locking position. This arrangement provides means for disconnecting the drawer rail from the slide so that the drawer may be lifted off the slide without the use of tools;
The invention also eliminates what in offices is called noise pollution caused by the noise and metallic clicking when drawers are moved back and forth in such units as file drawers, desk drawers, department store fixture drawers, etc. Thus, it contributes greatly to the improvement of office ecology;
In the automatic latching arrangement, there are certain very important features. As described above, it is necessary for the side of the rail that slides on the outer member of the slide mechanism to be free from any projecting parts and for this reason, the following is important.
Two holes are extruded upwardly from the rail to provide securing means for the spring latch which has two latching holes aligned with the extruded holes.
The extruded set-ups are then knurled over the spring latch surface thereby fastening it or securing it to the rail.
There is a third hole in the rail between the above mentioned two holes. This hole is merely punched out and receives a dimple in the spring latch which protrudes into the metal hole of the rail to lock it. In this arrangement then, the spring latch is not creating any shear forces upon the two outside knurled over extruded protrusions due to the dimple in the center locking it with the hole in the rail and thus taking the side shear forces. These shear forces are applicable when the latch drops into the slot of the outer member which is provided for the locking function. In other words, when the latch part drops into the slot provided therefor, in the outer member, the drawer is prevented from moving back and forth or being disconnected. Thus, the underside of the rail provides a flush surface resting on the upper ball race of the outer member.
A hold-in detent is holding the drawer in position when closed so that any slide forward tilt of the desk, cabinet or the like, will not let the drawer come out. Also, this hold-in detent arrangement, will prevent the drawer to come out when it is too forcefully closed.
The slide mechanism also includes provision whereby it is reversible, that is, it can be attached to either side of the drawer. Thus, it is not necessary to make right and left-hand mechanisms thereby reducing manufacturing costs.
It is also a part of the invention that it applied to an all-steel, ball bearing, precision, telescoping slide mechanism, which has been patented under US. Pat. No. 3,205,025.
The characteristics and advantages of the invention are further sufficiently referred to in connection with the following detailed description of the accompanying drawings which represent certain embodiments and arrangements. After considering these examples, skilled persons will understand that many variations may be made without departing from the principles disclosed, and l contemplate the employment of any structures, arrangements or modes of operation that are properly within the scope of the appended claims.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring more particularly to FIGS. 1 5, there is shown one embodiment of a slide mechanism embodying the present invention and indicated generally at 24. The mechanism includes the usual outer slide member indicated generally at 28 and an inner slide member, not shown, in FIGS. 1 5, but shown and described hereandafter.
In FIG. 1, there is shown a desk or cabinet 30 having a drawer 32, it being understood, of course. that there may be more than one drawer, the inner slide member in this figure being hidden from view since it is fastened to an adjacent part of the desk or cabinet.
Also, it is to be understood that there is a slide mechanism for each side of the drawer. As shown in FIG. 1, the drawer is in an outward or open position. The outer slide members of the slides at opposite sides of the drawer are free to slide into and out of the cabinet 30.
The outer slide member 28, FIG. 1, is shown to be in its extended position and it should be noted that the outer slide element is not affixed to the drawer side wall 34.
The means for attaching the desk drawer to the slides comprises an adaptor or drawer attachment, indicated generally at 36, which in cross-section, is shaped like a Z lying on its side. That is, there is a horizontal portion 38, a vertical upstanding portion or flange 40 along one longitudinal edge of the horizontal portion, and a depending portion or flange 42 along the opposite longitudinal edge.
The longitudinally extending vertical portion or flange 40 has a plurality of longitudinally spaced openings for screws 44 for attaching the adaptor 36 to side 46, FIG. 1, of the drawer 32.
The longitudinally extending horizontal portion 38 has a locking clamp, indicated generally at 48.
The locking clamp 48 comprise a lever 50 pivotly attached to the horizontal part 38, sometimes termed the rail, by any suitable means such as a rivet 54 adjacent one end so as to be freely movable in a horizontal plane.
Adjacent the opposite end is an upstanding ear 56 so that the lever may be easily actuated between locking and release position. Intermediate the ends of lever 50, there is a flange 60 depending at right angles from the outer edge of the lever and at the lower end of flange 60, is an inturned lip 62 normal to said flange 60. As shown, the locking lip 62 of the locking clamp 48 fits under and engages the free edge 64 of the outer slide member 28. When in this closed position, the locking clamp 48 now vertically locks together the adaptor 36 and the outer slide element 28, the engagement of the horizontal part 38 of the rail and the top of the outer slide member 28 effects secure locking together of the adaptor and the outer slide member.
To release the adaptor from the outer slide 28, latch 48 is manually actuated by means of the upstanding ear 56 to the release position shown in FIG. 3.
As shown in FIG. 5, there is also a locking block 68 which is affixed to the under side of the lever 50 by means of a rivet 70 although any other suitable fastening means may be used. The locking block 68 is adapted to fit into a locking slot 72 in the upper portion of the outer slide element 28. More specifically, slot 72 is in the upper ball race 74 of said outer slide member.
While the locking block 68 may be formed of any suitable material, it has been found preferable to use a resilient material such as rubber, urethane or the like. The locking block 68 has a fairly snug fit in the locking slot 72 of the outer slide element but a limited amount of longitudinal movement may occur and the resilient material is sound absorbing or muffling to substantially eliminate noise.
The drawer 32 is illustrated with its inner end positioned within the cabinet 30 and with the adaptor 36 resting on the top of the outer slide element 28. When installing the drawer, the locking clamps are open and the drawer is lowered onto the slide member 28, the lower surface of the horizontal part 38 of the adaptor coming to rest on the top of the outer slide element 28 so that the slide thus supports the weight of the drawer and its contents. Moreover, the locking block 68 of the locking clamp 48 enters the locking slot 72 of the outer slide element 28 when the locking clamp is moved to the closed position. Thus, the mutual engagement of these parts provides a longitudinal locking action that prevents the drawer from moving axially relative to the outer slide element 28. While it is not shown, there is a similar arrangement on the other side of the drawer 32 so that both sides of the drawer are longitudinally locked in place relative to the outer slide member of the slides and are supported thereby. When the locking clamp is moved to the closed position, the inturned lips 62 engage the free edge portion 64 of the ball races 74 of the outer slide members to lock the drawer against lifting or vertical movement.
Now, the drawer may be pushed into or pulled outwardly of the cabinet, the longitudinal locking arrangement between the locking block and the locking slot assure that the slide mechanism operates as designed, and also assures that the drawer may be easily removed by unlocking the locking clamp and lifting the drawer from he sides whenever so desired.
Once the drawer and its affixed adaptors 36 have been lowered onto the outer slide member 28, their respective cross-sections appear as indicated in FIG. 6. It will be seen from this illustration that the drawer side wall 46 and its affixed adaptor now engage the upper portion of the outer slide member 28 in such a way that the outer slide member 28 is pinched between the drawer side wall 46 and the vertical part 40 with the upper portion of the outer slide member 28 supporting the weight of the drawer by means of the horizontal part 40. Thus, the engagement of the depending part 42 of the adaptor, coacts with the upper ball race of the outer slide member to prevent transverse movement relative to each other and thus produces transverse locking between the drawer and the slide mechanism.
When the drawer is supported by the slide mechanisms, the horizontal portion 38 of the adaptor floats or slightly rests on the curved top portion of the top races 74 of the outer slide members 28. The depending flanges 42 of the adaptors depend along side the free edges of said top races of the outer slide member to thereby aid in retaining the drawer in proper alignment with the slides.
When the drawer is in its closed position, the inner and outer members of the slides are fully telescoped and the adaptor is fully retracted, that is, said adaptor is at its furthest inward position on the top bearing races of the respective outer slide members.
When the drawer is pulled out, the outer slide members 28 of the respective slides first move outwardly to their limit of movement. Up to the point at which the outer slide members are stopped by the usual limiting means, the adaptors remain at the position on the top races of the outer slide members, but, when the outer slide members are stopped, the drawer may be further pulled out with the adaptors sliding on said top races of the outer slide members of the slides at opposite sides of the drawer by releasing the locking clamps, the drawers thus being released and adapted to be pulled to the fully extending position whereat the rear end of the drawer is clear or substantially clear of the desk at the drawer opening.
Should it be desired to remove the drawer, it is pulled outwardly from the closed position to the fully extended position. it may then be lifted off the slides after the locking clamps have been released. To replace the drawer, the reverse procedure is followed.
Thus, it will be apparent that the drawer may be easily and quickly removed from the slides of the desk or cabinet and easily and quickly replaced. Further, it will be apparent that a drawer may be removed and replaced by another drawer.
The slides are also practically noiseless and extremely smooth in action. Opening and closing the drawers is practically effortless requiring but a light touch. Removal and replacement of drawers may be effected quickly and easily.
Another advantage of the present invention is that the outer slide member may be provided with a similar notch 72 in the'lower ball race. With this arrangement, the slides may be reversed. That is, the slides may be attached at either side without otherwise being specially constructed for such an arrangement.
FIGS. 8, 9, 10 AND 11 Referring to FIGS. 8, 9, 10 and 11, there is shown an alternative adaptor and slide arrangement.
The slide mechanism includes the outer slide member 28 of the ususal well-known character and an inner slide member 80, there being a ball retainer indicated generally at 82 which retains the ball bearings 83 and spaces them apart in the ball races of the inner and outer slide member. The upper ball race of the outer slide member is provided with a pair of notches 84 and 86, separated by-dividing part 87, notch 84 being of greater size than notch 86 and being closer to the end of the slide. Notch 86 is actually a rearward extension of notch 84 and connects with the rear of notch 84. Adjacent its inner end, the outer slide member has a raised tab 88 lanced from the upper ball race thereof and opening forwardly.
The slide member is attached within the inner desk opening or other fixed part, while the outer slide member carries the drawer as will be here and after fully described. The inner slide member has resilient parts 92 and 94 whereby said inner slide member is attached to the desk, cabinet or the like. It is to be noted that the outer slide member is provided with ridges in the bottom thereof and in the region of the openings 84 and 86 to thereby strengthen this part of the outer slide member.
Referring more particularly to the adaptor of FIGS. 8, 9, 10 and 11,.said adaptor is indicated generally at 96.
Adjacent the forward end of the adaptor rail is a down-turned and slightly in -turned guide and connector which is in the general shape of a U lying on its side and indicated generally at 135, the purpose of which will be described hereandafter.
The releasable clamping mechanism comprises a latch or locking arrangement comprising an elongated resilient spring 108. Spring 108 normally lies on the horizontal part 100 of the rail and the rear end of said spring is secured to said horizontal part of the rail by a unique fastening means comprising upward extrusions 110 from the horizontal part of the rail so that the under surface of the horizontal part 100 of the rail is smooth. There are two holes in the spring latch 108 through which the extrusions 110 extend and are riveted over at their ends 112 thereby securing the spring latch to the horizontal part of the rail. A hole 114 is also provided in the horizontal part of the rail intermediate the extrusions 110 and a dimple 116 formed downwardly in the spring latch, extends into hole 114 and does not extend below the lower plane of the spring latch. This provides a very effective lock so that the spring latch does not create any shear forces upon the two extruded parts since the dimple thus takes any side shear forces. These shear forces are applicable when the latch drops into the slot of the outer member preventing the drawer from moving backward and forward or being disconnected.
At the forward free end of the spring latch 108, there is a holder for a piece of sound muffling material 120, the holder for this material comprises a pair of depending ears 122 spaced apart and having inturned end portions 124 which extend beneath the piece of material 120. Thus, the piece of material 120 is clamped between the inturned portions 124 and the adjacent part of the spring latch. Toward the rear of the piece of material is a downwardly and forwardly inclined tongue 126, which functions as a cam, and is lanced from the spring latch and normally rests in the notch extension 86 as best shown in FIGS. 8 and 9. Spring latch 108 has an upturned flange-like structure 127 which is at the side adjacent the upturned flange 102. This structure has an opening therein with a vertical part 128 adapted to be slidingly received in the space between an ear 130 lanced from the vertical part 102 of the rail and spaced outwardly a sufficient distance to slidingly receive the vertical part 128. Structure 127 has a laterally turned flange 132 which is adapted to be engaged by the thumb or other digit of the operator and an outwardly turned stop 134 is lanced laterally from the vertical flange 102. Stop 134 is spaced upwardly of the spring latch a sufficient distance to permit the free end of the latch to be raised to clear the material 120 and the tongue 126 from the openings 84 and 86 thereby releasing the adaptor from the outer slide member.
With the adaptors attached to the respective sides of a drawer, the drawer is placed on the slide members with the horizontal part of the rail of the adaptor resting on the upper ball races of the outer slide members. When thus placed on the ball races of the outer slide members, the muffling material or block 120 and the tongue or cam 124 rests on the horizontal part of the rail forwardly of notches 84 and 86 and is forced upwardly against the spring tension of spring latch due to the weight of the drawer. The drawer is then slid rearwardly and, as this is done, the outer end of the upper ball race, which is slightly notched along the free edge, slides into the guide and connector 135 thereby interconnecting the front end of the adaptor and the front end of the outer slide member. Slightly further movement of the drawer rearwardly causes the rear end of the horizontal part of the rail to pass beneath the tab or car 88 thereby interconnecting the rear end of the adaptor and the rear end of the outer slide member. These end parts become interconnected prior to the entrance of the block or muffling material 120 into the forward opening in the upper ball race of the outer slide member. As the drawer is moved further rearwardly, the free end of the cam 126 passes onto the dividing part 87 and keeps the forward free end of the latch spring 108 raised. Still further rearward movement of the drawer causes the free end of the cam 126 to drop into the opening 86 of the upper ball race of the outer slide member and simultaneously allows the block or muffling material to drop into the opening 84, thus, preventing linear or longitudinal movement of the adaptor and outer slide element. The structure 127 is held against lateral displacement by the ear 130.
To remove the drawer from the slide mechanisms, the forward free end of the spring latch is raised by means of the flange 132 to a position whereat said spring latch engages the stop 134 thus clearing the block 120 and the cam 126 with respect to the upper ball race of the outer slide member. The drawer then may be moved forwardly to disengage the forward ends of the adaptor and outer slide member as well as the rear ends of these parts. The drawer may then be lifted from the slides and removed. Replacing of the drawer is effected by placing it on the slide mechanisms with the horizontal part 100 of the rail of the adaptor resting on the upper ball race of the outer slide members. Securing the adaptors and outer slide members together is effected as above described.
Laterally-turned flange 138 provides a stop at the rear part of the slide mechanism and there is a block 140 which serves as a bumper and sound muffler. This block is attached to the central part 142 of the ball retainer, said bumper projecting longitudinally outwardly of the ball retainer and clamped onto said central part 142 by means of a shallow channel-shaped bracket 144 which is attached to the central part of the ball retainer by means of a rivet 146. A similar bumper is similarly attached to the opposite end of the ball retainer. Thus, clicking noises are effectively muffled when either end of the ball retainer strikes a stop. It is also to be noted that the sides 148 of the bracket 144 has inturned end parts 150 which aid in preventing displacement of the bumpers as they strike stops.
HOLD-IN STOPS FIGS. 14 17 INCLUSIVE In one type of slide mechanism, there is an intermediate member indicated generally at 200, having a horizontal part 202 with upwardly and downwardly extending flanges 204 and 206. This member has a notch or opening 208 intermediate its ends and there is a roller 210 of resilient material such as rubber, plastic or the like carried on a rivet 212 or the like. The rivet may be of any suitable type and extends through openings provided therefor in ears 214 extending downwardly and upwardly from the respective flanges 204 and 206.
There are a pair of slide mechanisms secured to the flanges 204 and 206, the inner slide members thereof being the parts secured to said flanges. The slide members are in generally the same plane and the lower ball race of the outer slide member of the upper slide mechanism is provided with a depending arcuate shaped boss 216 and the upper ball race of the outer slide member of the lower slide mechanism is provided with a similar boss 218. These bosses are in the path of movement of the roller 210 and when the slide members are in the retracted position, the bosses 216 and 218 are at opposite sides of the roller 210 and substantially in contact with the periphery of said roller. Thus, when the slide mechanisms are telescoped and in their retracted position, they are normally held against extension by reason of the bosses engagement with the roller 2").
While the slide mechanisms are held against extension by the bosses, said slide mechanisms may be extended by a force sufficient to overcome the holding of the roller between the bosses. Since the roller is of resilient material, it does not require a great deal of force to release the slide mechanisms to permit their extension.
This arrangement is for the purpose of releasably holding the drawer or the like supported by the slides in the closed position so that the drawer will not slide open should the cabinet, desk or the like be slidably inclined in a direction that would otherwise cause the drawer to slide open. Also, this arrangement, prevents the drawer from snapping or bumping out when it is closed.
Referring to FIG. 18, there is shown an alternative hold-in stop mechanism. In this arranagement, the bottom wall 220 is provided with a pressed-out portion indicated generally at 222. This portion has a part 224 inclined laterally and toward the adjacent end of the slide member. At the rear end of the part 224, there is a part 226 which is curved toward the adjacent wall of the slide member to provide a hump 228. The other slide member 230 is provided with a frictional button of a suitable plastic, such as, for example, nylon, teflon or the like. This button is secured to the bottom of the slide member 230 by means of a rivet 234 or any other suitable means. The free end of the buttom is rounded and is adapted to be at the outer side of the hump 228 when the slide members are telescoped and thus, hold the slide members in the telescoped position under normal conditions. When it is desired to extend the slide members, a sufficient force may be readily applied to cause the button to ride over the hump 228 and thus release the slide members for normal extension.
Both of these arrangements serve the same purpose of holding the slide members in a telescoped position so that the drawer carried by the slides, will not inadvertently slide open. The resistance of the parts holding the slide members telescoped is not great and the drawer may be readily pulled open.
SUMMARY Thus, we have provided slide mechanisms which have means for removably mounting drawer slides and latching or locking drawers on the slides. The mounting means comprise adaptors attached to the sides of a drawer and the latching or locking means for securing the adaptors and the slide mechanisms together, hold the adaptors from being lifted from the slide mechanisms and also hold the adaptors from sliding on the slide mechanisms when the latching means are in the latching or locking position. Also, by having the notches or openings for the latching means on both upper and lower parts of the outer slide members, the slide mechanisms may all be formed the same and a mirror reversal of the slide mechanisms make it possible to use these same slide mechanisms for either side of the drawer.
There are also novel bumper arrangements for muffling noises when parts of the slides reach stops. I
A further feature of the present invention includes hold-in stops which hold the drawer in position when closed so that any slide forward tilt of the desk, cabinet or the like will not let the drawer come out. Also, holdin stops or detents, prevent the drawer from bumping out when it is too forcefully closed.
The invention and its attendent advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts of the invention without departing from the spirit or scope thereof or sacrificing its material advantages, the arrangement hereinbefore described being merely by way of example, and we do not wish to be restricted to the specific form shown or uses mentioned except as defined in the accompanying claims.
