DETAILED DESCRIPTION OF THE INVENTION

(6) In the following description, numerous specific details are set forth in order to provide a more thorough description of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without these specific details. In other instances, well-known features have not been described in detail so as not to obscure the invention.

(7) One embodiment of the invention is a work support, such as a sawhorse. The sawhorse may be referred to as a light duty sawhorse in that it is configurated to be lightweight and compact in its collapsed position.

(8) As illustrated in FIG. 1 a sawhorse 20 has two pair of legs 22a,b and 24a,b (e.g. the first pair of legs comprising a first leg 22a and a second leg 22b and the second pair of legs comprising a third leg 24a and a fourth leg 24b). Each pair of legs 22a,b and 24a,b is connected at a top end to a bracket 26a,b. A cross-member or head 30 is preferably connected to, and extends between, the two brackets 26a,b

(9) In one embodiment, each leg 22a,b, 24a,b has a top end and a bottom end. The legs 22a,b, 24a,b may have various configurations, but in one embodiment, are designed to be relatively lightweight, such as by being constructed from 11 to 22 inch square metal tubing. In one embodiment, a foot 32 is located at the bottom end of each leg 22a,b, 24a,b. The foot 32 may comprise a cap or similar member which is located over for fits within and extends from the bottom end of each leg, where the cap may be constructed of rubber, plastic or a similar durable material.

(10) As indicated, the top end the first and second legs 22a,b are connected to one of the brackets 26a, and preferably movably connected thereto. As best illustrated in FIG. 2, the two brackets 26a,b may each have a first side 34, a second side 36, a front 38, a rear 40, a top 42 and a bottom 44. In one embodiment, the first leg 22a is connected to a first side 24 of the bracket 26a, and the second leg 22b is connected to the second side 36 of the bracket 26a, and below the head 30 (e.g. generally at the bottom 44 of the bracket 26a and at an inside of each side 34,36). The first and second legs 22a,b are preferably independently movable relative to one another in a manner which permits the legs 22a,b to rotate between an open or extended position and a closed or retracted position. In one embodiment, the legs 22a,b are connected to the bracket 26a by a pin 46 or similar member, which permits each leg 22a,b to rotate relative to the bracket 26a.

(11) As illustrated in FIG. 2, the bracket 26a may include a guide 48. The guide 48 may be positioned between the first and second legs 22a,b, such as for providing lateral support to the top ends of the first and second legs 22a,b, particularly when they are in their extended position. As illustrated, the guide 48 may be wedge shaped, thus defining sloping faces which engages sides of the first and second legs 22a,b.

(12) The second pair of legs (e.g. the third and fourth legs) 28a,b is similarly connected to the second bracket 26b.

(13) In one embodiment, the front 38 of each bracket 26a,b is generally opening, thus permitting the pairs of legs 22a,b, 24a,b to rotate towards one another to their retracted or collapsed position. In one embodiment, the rear 40 of each bracket 26a,b is generally closed and may thus serve as a stop which limits rotation of the legs 22a,b, 24a,b towards their open or extended position, and also provide a location for mounting of other elements, as described below.

(14) In one embodiment, the top 42 of the head 30 may define a channel 52 which is partially inset between the first and second sides 34,36. The channel 52 may extend from the front 38 of the bracket 26a,b towards the rear 40, such as entirely through the bracket 26a,b.

(15) In the embodiment illustrated, the head 30 may comprise a generally low-profile body, such as having a rectangular cross-section (such as of tubing), where a width of the head 30 may be greater than a height thereof. The head 30 has a first end and a second end, where the first end is located in the channel 52 of one bracket 26a, and the second end is located in the channel 52 of the other bracket 26b. In one embodiment, the depth of the head 30 is generally the same as the depth of the channel 52, so that the top of the head 30 is at (e.g. generally flush with) the top 42 of each bracket 26a,b. In one embodiment, the head 30 may be connected to each bracket 26a,b with one or more fasteners, such as extending through the side(s) 34,36 of the brackets 26a,b. In one embodiment, the head 30 might be removeable.

(16) The head 30 separates the brackets 26a,b and thus the pairs of legs 22a,b, 24a,b. The length of the head 30 may vary, such as depending on the desired size of the sawhorse 20.

(17) As illustrated in FIGS. 2 and 3A, a hook or similar support 54 may be located at either or both ends of the sawhorse 20. The hooks 54 might comprise, for example, a generally U shaped bracket which is designed to support a 24 (whereby the width of the bracket may be 1.5-2 inches). In one embodiment, the hooks 54 may be mounted to the rear 40 of the brackets 26a,b. The hook 54 might be connected to the bracket 26a,b via an outwardly extending flange which fits into a slot 50 in the bracket 26a,b (such as to be easily removable therefrom, such as when transporting or storing the sawhorse 20). As illustrated in FIG. 4, the sawhorse 20 of the invention may be used to support one or more workpieces, such as when used with a second sawhorse 20. For example, one or more workpieces might be supported on the head 30 or by the hook 54.

(18) As indicated above and illustrated in FIGS. 3A and 3B, the pairs of legs 22a,b, 24a,b may be moved between an open or extended position (for supporting the head 30 in a raised position above a surface or support) and a closed or retracted position. In the closed or retracted position, the pairs of legs 22a,b, 24a,b may fold inwardly so that they extend generally parallel to and along the bottom of the head 30, as best illustrated in FIGS. 5-6.

(19) In one embodiment, at least one locking or securing means are provided for securing the legs 22a,b, 24a,b in their open and/or closed positions. In one embodiment, and referring to FIGS. 2 and 3A-3B, a locking mechanism may be provided relative to each leg. The locking mechanism may comprise a biased pin 58 which is associated with each leg 22a,b, 24a,b, such as being located partially within each leg, where a spring or other biasing element (not shown) biases the pin outwardly from the leg, such as through an aperture therein, and where the pin 58 can be pressed inwardly into a compressed or retracted position.

(20) The sides 34,36 of the brackets 26a,b, preferably define a first opening 60 and a second opening 62. The first opening 60 is positioned so that when the corresponding leg 22,a,b, 24a,b is moved to its open or extended position, the pin 58 associated with that leg is biased outwardly and extends through the opening 60, thus effectively locking or retaining the leg in its open position. The second opening 62 is positioned so that when the corresponding leg 22a,b, 24a,b is moved to its closed or retracted position, the pin 58 associated with that leg is biased outwardly and extends through the opening 62, thus effectively locking or retaining the leg in its closed position. The user may release the legs 22a,b, 24a,b from their locked positions by pressing the pins 58 inwardly.

(21) Other means for locking might be used, such as fasteners, clips, latches and the like.

(22) In one embodiment, means are provided for joining or connecting two sawhorses 20 of the invention when the legs thereof are in the retracted or collapsed position. As best illustrated in FIGS. 5-7 this means may comprise a movable latch 64 and a catch 66. As illustrated, a movable latch 64, such as a lever-operated capture or hook, is located at an end of one of the brackets 26a,b, and a catch 66, such as a catch block, is located at an end of the other bracket 26a,b. Two sawhorses 20 may be located proximate to one another in reverse orientation, so that the latch 64 on one sawhorse can be engaged with the catch 66 on the other, and vice versa. So connected, the two sawhorses 20 may be easily transported or stored or the like.

(23) In a preferred embodiment, as illustrated, when the legs 22a,b, 24a,b are moved to their retracted position, they extend generally along and parallel to the head 30. Further, they do not extend below the bottom of the sides 34,36 of the brackets 26a,b. Thus, when two sawhorses are connected, as illustrated in FIGS. 5-7, the legs are captured or contained between the heads 30 and associated brackets 26a,b, such as with the heads 30 facing outwardly and the bottoms of the sides 34,36 of the brackets 26a,b of the two sawhorses 20 engaging one another.

(24) The sawhorse of the invention has numerous advantages. One advantage is a lightweight sawhorse which is easy to use, transport and store. In one embodiment, when the legs of the sawhorse are moved to their closed position, they fold along the head of the sawhorse and extend parallel thereto, such that the sawhorse has a compact dimension in its collapsed position. Further, two sawhorses may be connected to one another so that they can be transported and/or stored together.

(25) It will be understood that the above described arrangements of apparatus and the method there from are merely illustrative of applications of the principles of this invention and many other embodiments and modifications may be made without departing from the spirit and scope of the invention as defined in the claims.
