Abstract
A “harp rack” for the storage and shipping of sheet material modified so that the stringers are rotatably mounted for simultaneous rotation relative to a supporting base and frame between a locking position and a release position, the stringers each have locking vanes disposed on opposite sides which terminate in a glass engaging stopper such as rubber.
Description
- This invention relates to racks for packaging, storing and transporting sheet material, particularly glass, but also metal, plastic, marble plates, windows and doors.
- Glass panes are usually produced, cut to specific sizes required by the end user and shipped as lites in pallets which may be boxed in wooden cases. Glass lites are also moved around on factory floors using wheeled pallets known as “harp racks” which consist of steel rods covered with plastic sleeves, mounted to a frame and usually inclined at an angle of approximately 50° to separate glass panes supported on a slotted base. The harp racks are available in many configurations and can have one or two levels or decks disposed one above the other, optionally with an inner string set of shorter rods to accommodate and separate glass panes having smaller dimensions and an outer string set of longer rods to accommodate and separate larger glass panes. While the harp racks may be used for transportation off-site by using plastic shrink-wrap to immobilize the glass lites on the racks, this is not a satisfactory solution and harp racks are not generally considered suitable for shipping glass lites to another location.
- An object of this invention is to provide means for securing sheet material in a harp style rack so that the same rack may be used for moving the sheet material at the pick-up and delivery locations without any intermediate loading and unloading for shipping between locations and without the need for plastic shrink wrap or other securing devices.
- In accordance with this invention, there is provided a so-called “harp rack” in which the stringer assembly is modified so that the stringers are rotably mounted for simultaneous rotation relative to a supporting base and frame between a locking position and a release position, the stringers each having transversely extending locking means disposed on opposite sides and terminating in a glass engaging stopper such as rubber.
- In order that the invention may be more clearly understood, a preferred embodiment is described below with reference to the accompanying drawings, in which:
-
FIG. 1 is a perspective view of a double level, double string locking harp rack made in accordance with the invention; -
FIG. 2 is a top plan view of a glass pane trapped between a pair of stringers rotated into a locking position; -
FIG. 3 is a top plan view similar toFIG. 2 showing the stringers rotated into a release position; -
FIG. 4 is an exploded view showing a stringer assembly and a frame for the locking harp rack; -
FIG. 5 is a perspective view showing the stringer assembly ofFIG. 4 in an assembled configuration; and -
FIG. 6 (drawn to a larger scale) is a side elevation of a portion of the stringer assembly ofFIG. 5 . - A locking harp rack made in accordance with the invention is generally indicated by
reference numeral 20 inFIG. 1 . Like prior art harp racks, theharp rack 20 has abase 22 which has a series of spacedparallel grooves 24 that extend along the length of thebase 22 to support sheets of glass and the like (not shown). Thebase 22 is conveniently made of synthetic plastic material such as high density polyethylene which can be cut to form thegrooves 24. Thebase 22 is supported in aframe 26 on lockingcaster wheels 28. Anupper deck 30 similar to thebase 22 is vertically disposed above thebase 22 to accommodate a second tier of sheets or glass panes. - A plurality of
stringers 32 are mounted to theframe 26 and are spaced from each other along the width of thebase 22 between each of thegrooves 24 to form a lower string set 34 inclined at about 50° between the base and a horizontally extendingmounting channel 38 forming part of theframe 26. Anupper string set 36 is inclined at a similar angle between theupper deck 30 and a respective horizontally extendingsupport 40. In the embodiment illustrated, thebase 22 and theupper deck 30 each support an inner string set 42, 44 to accommodate sheets or glass panes having smaller dimensions. Theinner string sets - The
stringers 32 in thelower string set 34 have been modified in accordance with this invention to be rotatable relative to the horizontally extendingsupport 38 and thebase 22 between a locking position and a release position using anoperator handle 46. - The construction of the
stringers 32 will now be described with particular reference being made toFIGS. 2, 3 and 6. Eachstringer 32 has a pair ofmetal rod terminations 48 fitted and welded to a longitudinally extendingcentral metal plate 50. Themetal plates 50 have a narrow width of z-shaped cross-section (FIGS. 2, 3 ) that defines a pair of transversely extending locking vanes disposed on opposite sides of thestringers 32. The free edges of themetal plate 50 are covered by arubber stopper 52 consisting of a narrow strip of rubber sheet glued to opposite sides of the metal plate so that only soft resilient material will engage aglass sheet 54 received in agroove 24. Thelower rod termination 48 is received in a journal-bearing formed in a bottom guide plate 56 (FIG. 4 ) disposed in thebase 22. - Rotation means for rotating the
stringers 32 will now be described with reference toFIGS. 4, 5 , 6. Theupper rod terminations 48 traverse themounting channel 38 forming part of theframe 26 through a series ofrespective apertures 39 formed therein and are received in respective journal bearings formed in anupper rod guide 58 fixed to thechannel 38. Theupper rod terminations 48 each have arespective spring arm 60 extending transversely to the axis of therod terminations 48 which engages asliding plate 62. - The
sliding plate 62 is slidably mounted in thechannel 38 through threesliding guides 64 spaced across the width of thechannel 38 and having a groove for slidably receiving thesliding plate 62. Respective pins 66 traverse thesliding guides 64 and are received incorresponding slots 68 formed in thesliding plate 62. The upper edge of the sliding plate (as drawn) is castellated or notched to receive arespective spring arm 60 and aspring biasing coil 70 in each notch whereby contact is maintained between thesliding plate 62 and thespring arm terminations 60. - The
external operator handle 46 is pivoted to the frame atpivot pin 72 and carries a connectingrod 74 which is coupled to one end of thesliding plate 62 so that rotation of thehandle 46 causes translation of thesliding plate 62, as indicated by arrow 76. It will be noted that the connectingrod 74 is threaded so that its length may be adjusted for tighter or looser locking force. Meanwhile, downward rotation of theoperator handle 46 from the release position (as drawn) will cause thehandle 46 to traverse the center of rotation ofpivot pin 72 and come to rest in an over-centre locking position. - In use, such rotation of the
operator handle 46 to pull thesliding plate 62 to the left (as drawn) allows thespring coils 70 to expand and bear against thespring arms 60, thereby rotating thestringers 32 as indicated byarrow 78 inFIG. 2 to cause thestoppers 52 to firmly engage theglass sheet 54 at substantially right angles on opposite sides thereof. - Each
glass sheet 54 is thus trapped between a pair ofstringers 32 each of which makes line contact with theglass sheet 54 along the length of thestopper 52. Release of the glass sheets as shown inFIG. 3 can only be achieved by positively moving theoperator handle 46 upward to bring the handle over the center of rotation ofpivot pin 72 and to push thesliding plate 62 against thespring arms 60 so that thespring coils 70 are compressed (as drawn). Pushing against thespring arms 60 causes thestringers 32 to rotate in the opposite direction as shown byarrow 80 inFIG. 3 thereby bringing the stringers to a release position where thestoppers 52 are spaced from theglass sheet 54. - It will be understood that several variations may be made to the above-described embodiment of the invention within the scope of the appended claims, as will be apparent to those skilled in the art. In particular, the shape and configuration of the stringers may be varied to have for example, a plurality of stoppers each making point contact with the sheet and the mechanism for rotation of the stringers may be substituted by others, such as, for example, a rack and pinion means for translating a carriage to rotate the stringers. Other such variations will be apparent to those skilled in the art and will be considered mechanical equivalents to the embodiment described.
