The present disclosure relates to a workbench and more specifically to a collapsible portable workbench having portions that can be separated from one another to form a pair of saw horses.
Collapsible portable workbenches incorporating a workpiece clamping device provide a convenient structure to secure a workpiece while performing a tooling operation. This type of collapsible, clamping workbench generally includes a pair of top members, one of which is fixed to a supporting structure, while the other is adjustable along the supporting structure toward and away from the first one of the top members by a screw-type handle translation device.
While such collapsible portable workbenches can work extremely well with workpieces of moderate and small sizes, they are often times insufficient when relatively large workpieces, such as a full-sized sheet of plywood or oriented strand board (OSB) or longer lengths of structural lumber.
In one form, the present teachings provide a workbench that includes a collapsible frame, a plurality of table panes and a second leg set. The collapsible frame has a first leg set that is movable between a first position in which the collapsible frame is in a collapsed condition and a second position in which the collapsible frame is in an expanded position. The plurality of table panels are coupled to the first leg set. The second leg set is coupled to a first one of the plurality of table panels and is positionable in a retracted position and an extended position.
In another form, the present disclosure provides a first leg set, first and second table panels coupled to the first leg set, a lead screw and a second leg set. The lead screw movably couples the first table panel to the first leg set and is rotatable to affect a position of the first table panel relative to the first leg set. The second leg set is coupled to the second table panel. The second table panel can be selectively de-coupled from the first leg set to permit at least portion of the second leg set and the second table panel to form at least one of a saw horse and a work bench.
Further areas of applicability will become apparent from the description provided herein. It should be understood that the description and specific examples are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure, its application and/or uses in any way.
The drawings described herein are for illustration purposes only and are not intended to limit the scope of the present disclosure in any way. Similar or identical elements are given consistent identifying numerals throughout the various figures.
With reference to
The collapsible frame 12 can be formed in any desired manner, such as that which is described in U.S. Pat. Nos. 4,061,323; 4,278,243; 5,383,977; 7,090,210; or 7,232,120, the disclosures of which are hereby incorporated by reference as if fully set forth in detail herein. The collapsible frame 12 can include two laterally spaced-apart first leg sets 20 that are movable between a first position (
Also in the example provided, the collapsible frame 12 can include structure for supporting the first leg sets 20, such as various struts or spacers 26 that can be disposed between the first leg sets 20, latches or locks 28 that can be latched or locked to thereby maintain the collapsible frame 12 in the first position and/or second position, wheels 30, which can be coupled to the second end of the first legs 22, and a lift truck structure 32 having a toe plate 34 and a release mechanism 36 that can be employed to lock the toe plate 34 in the raised position (
With reference to
Each of the mount structures 42 can include a first mount member 60 and a second mount member 62 that can be pivotally coupled to the first mount member 60 and movable between a lowered position, which is shown in
With reference to
With reference to
A third one of the top members 84 can be mounted on the internally threaded members 52 so that rotation of the handles 54 will cause corresponding translation of the third top member 84 along the screws 50. As the screws 50 are carried by the second mount members 62, the third top member 84 can be locked in a lowered position which is shown in
With reference to
With reference to
It will be appreciated that the leg lock 140 could employ other means to retain the legs 132 in the extended or retracted positions. For example, a plurality of latches 150 could be coupled to the second top member 82 as shown in
With reference to
A second embodiment of a workbench constructed in accordance with the teachings of the present disclosure is illustrated in
With additional reference to
The first leg set 20a can include a pair of first legs 22a that can be pivotally coupled to the first frame member 200 and the second leg set 120a can include a pair of second legs 250 that can be pivotally coupled to the second frame member 202. The first and second leg sets 20a and 120a can be moved between an extended position, which is shown in
Similar to the previously described embodiment, the collapsible frame 12a can include structure for supporting the first and second leg sets 20a and 120a, such as various struts 260 and spacers (not shown) that can be disposed between the legs 22a and 250 of the first and second leg sets 20a and 120a, respectively, as well as latches or locks (not specifically shown) that can be latched or locked to thereby maintain the collapsible frame 12a in a opened or working condition and/or a collapsed condition.
The support structure 14 can include a pair of mount structures 42a, which can be integrally formed with the first and second frame members 200 and 202, and an adjustment mechanism 44a having a pair of screws 50a, a pair of internally threaded members 52a and a pair of handles 54a. Each of the screws 50a can be received in a corresponding one of the mount structures 42a and threadably engaged to one of the internally threaded members 52a. Each handle 54a can be coupled to an end of one of the screws 50a such that rotation of the handle 54 causes corresponding rotation of the screw 50a.
The top structure 16a can include a plurality of elongated panels or top members 80a and 84a having clamping surfaces 90a and upper surfaces 92a that are disposed in a common plane. A first one of the top members 80a can be removably coupled to the mount structure 42a. For example, the first top member 80a can be constructed with a pair of locking members (not specifically shown) that are similar to the locking members 100 described in the previous embodiment illustrated in
With reference to
It will be appreciated that the above description is merely exemplary in nature and is not intended to limit the present disclosure, its application or uses. While specific examples have been described in the specification and illustrated in the drawings, it will be understood by those of ordinary skill in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the present disclosure as defined in the claims. Furthermore, the mixing and matching of features, elements and/or functions between various examples is expressly contemplated herein so that one of ordinary skill in the art would appreciate from this disclosure that features, elements and/or functions of one example may be incorporated into another example as appropriate, unless described otherwise, above. Moreover, many modifications may be made to adapt a particular situation or material to the teachings of the present disclosure without departing from the essential scope thereof. Therefore, it is intended that the present disclosure not be limited to the particular examples illustrated by the drawings and described in the specification as the best mode presently contemplated for carrying out the teachings of the present disclosure, but that the scope of the present disclosure will include any embodiments falling within the foregoing description and the appended claims.
