No. 2,860,939 there is disclosed a slide assembly for extension tables, which comprises a pair of slide members maintained in a slide fitting relationship by an essentially U-shaped strap fixed to one of the members. The other member is punched to define a pair of stops arranged adjacent its opposite ends for engagement with opposite ends of the strap in order to define open and closed positions of the members.
While slide assemblies of the type described in U.S. Pat. No. 2,860,939 have enjoyed wide commercial use, they have however always been subject to one problem, which until the present invention has never been satisfactorily resolved. In this connection, it is desirable to provide the slide members with a relatively loose fit in order to permit free sliding movements thereof between their extreme or opened and closed positions. On the other hand, it would be desirable to provide the slide members with a relatively tight fit in order to resist vibration induced movement of the slide members from adjacent either of their extreme positions, which would otherwise result in a noticeable crack" or separation occurring between the table leaves. As a practical matter, these objects are contradictory, and therefore in installations wherein the presence of a crack between leaves is unacceptable, separate manually operable latching devices have been employed in combination with this prior form of slide assembly.
SUMMARY OF THE INVENTION The present invention is primarily directed towards an improvement in the slide assembly disclosed in U.S. Pat. No. 2,860,939, which permits the slide members to resist movements from adjacent their extreme positions, while permitting free sliding movements thereof between such positions.
More particularly, the preferred form of the present invention features a pair of detents arranged to frictionally or deformably engage the strap only when the latter engages or is in proximity to the stops determining the extreme positions of the slide members. Specifically, one detent is disposed immediately adjacent the stop defining the closed position of the slide members such that it frictionally interferes with relatively sliding movement of the members essentially only when the members are in closed position. The other detent is spaced from its associated stop through a greater distance in order to permit it to be effective for frictionally interfering with relative sliding movements of the slide members over a substantially greater range of such movements. By this means, the latter detent is effective even when different size leaves are inserted in the table.
DRAWINGS The nature and mode of operation of the present invention is more clearly described in the following detailed description taken with the accompanying drawings wherein:
FIG. 1 is a perspective view of the slide assembly of the present invention with the slide members in a closed or unextended position;
FIG. 2 is a view similar to FIG. 1, but showing the slide members in open or extended position;
FIG. 3 is a sectional view taken generally along the line 3-3 in FIG. 1;
FIG. 4 is a side elevational view of the assembly shown in FIG. 2; and
FIG. 5 is a sectional view taken generally along the line 55 in FIG. 4.
DETAILED DESCRIPTION The slide assembly of the present invention, which is generally designated as 10 in FIGS. 1, 2 and 4, is similar in overall construction to that described in U.S. Pat. No. 2,860,939. As by way of further reference, it will be understood that slide assemblies of this type are conventionally employed in pairs for the purpose of slidably interconnecting a pair of permanent table leaves, whereby to permit the permanent table leaves to be brought together in edge to edge contact when the assembly is moved towards its closed or unextended position illustrated in FIG. 1, or to be moved apart sufficiently to receive an additional table leaf therebetween when the assembly is moved towards its open or extended position illustrated in FIG. 2. Also, slide assemblies of this type are available in various sizes or lengths as required to accommodate a desired number of additional table leaves. For any given installation, the slide assemblies employed would permit the permanent leaves to be moved apart through a distance in excess of the width of the maximum size additional table leaf to be employed in order to facilitate insertion of such leaf.
In accordance with the present invention, slide member 14 is additionally provided with detents 24 and 26, which are formed by punch deforming vertical section 14b intermediate stops 20 and 22. Deforming operation results in the detents being formed with generally rectangular, relatively flat central portions 24a and 26a,
which are bounded by inclined surface portions 241; and 26b, respectively.
The height of detent central portions 24a and 26a relative to the planar surface of vertical section 1412 is at least sufficient to provide for slide assembly movement restraining frictional engagement between the detent central portions and the inner surface 16b of strap leg 16b, when slide members 12 and 14 are in their closed and opened positions, respectively. Preferably, the height of detent central portions 240 and 26a is such as to effect resilient deformation of strap 16 to an extent sufficient to positively force or bias the vertical and U- shaped sections of slide member 14 into frictional surface engagement with like sections of slide member 12, as best shown in FIGS. 3 and 5. In either construction, the facing detent inclined surface portions 24b and 26b serve as guiding or camming surfaces engageable by the opposite ends or vertically upstanding marginal edges of strap leg 16b in order to facilitate positioning of strap inner surface 16b in engagement with detent surfaces 24a and 26a.
By referring primarily to FIGS. 1, 2 and 4, it will be noted that detent 24 is disposed essentially immediately adjacent stop 20 such that it causes frictional interference with the relative movement of slide members 12 and 14 essentially only when the slide members are in their closed position. By comparison, detent 26 is preferably spaced through a greater distance from its associated stop 22 in order to permit it to cause frictional interference with the relative movement of the slide members over a substantially greater range of such movements adjacent the slide member open position. By this arrangement, the slide members are loosely fitted for free sliding movement during a substantial portion of the range of opening and closing movements, but are frictionally locked to prevent forming of a crack between the permanently attached leaves when the slide members are in their closed position and the forming of a crack" between the permanent table leaves and an additional table leaf when the slide members are adjacent their open position. By positioning detent 26 in the manner described, the additional leaf intended to be inserted in the table may have a range of sizes or widths.
It will be appreciated that as a practical matter, the closed position of the slide members may vary slightly from that illustrated in FIG. 1 after the assembly is installed in a table, since marginal edge engagement of the permanent table leaves will normally prevent full closing movement of the slide members. Thus, stop 20 is normally employed only to prevent disassembly of the slide members during handling and/or shipment to a point at which they are physically affixed to the permanent table leaves.
What is claimed is:
1. In a slide assembly for an extension table having a pair of slide members adapted to be individually fixed to permanent leaves of said table and a strap fixed to an end of one of the slide members to retain the slide members in a relatively loose fitting, free sliding relationship for movement between spaced positions wherein said leaves are alternately disposed adjacent to and remote from one another, said strap having a surface thereof arranged in a facing relationship to the other of said slide members, the improvement comprising:
