Abstract
A rack for hanging room sized carpets in show rooms. The rack has a plurality of uprights, each of which has a horizontal arm supporting a hanging carpet. The arm is adapted to be raised and lowered by a belt entrained on a motor-driven pulley and moved by a gear drive type motor. The belt and motor-driven pulley are mounted on the rack.
Description
This invention relates to display racks and more particularly to improvements in display racks for hanging room sized carpets.
It is desirable to have carpets hanging in such a manner in order that a number of carpets can be viewed without moving a large number of carpets. However, raising the carpets to a hanging position can not be done conveniently without proper equipment and furthermore, customers may request that the hanging carpet be spread horizontally. It is desirable therefore, that a sales person be provided with a motorized rack to conveniently raise and lower any carpet with a minimum of effort.
Attempts to provide display racks of this type include applicant's U.S. Pat.
No.5,292,011 which discloses a winch and cable system and U.S Pat. 2,000,336 which discloses a horizontal carpet support raised by pulling a rope. Other prior attempts include those disclosed in U.S. Pat. Nos.
3,187,900, W. Schneider; and 3,330,418, W. Schneider.
It is considered desirable therefore, to provide a display rack having display rack arms which will be capable of being driven by individual motors.
A still further consideration is that of minimizing damage to expensive carpets by exposed moving parts such as cables.
Accordingly, the present invention provides a display rack secured in an upright position for hanging carpets. The rack comprises an upright support member, an arm assembly including a horizontal member, and a diagonal brace for movement from a lowered position to an upper storage position. The horizontal member has an upper support roller bearing on a side of the upright support; a lower support roller on an end of the diagonal brace bearing on a side of the support opposite from the upper support roller and a worm drive winch on the upright tubular member whereby a flexible belt member extends over a drive pulley on an upper end of the support and has an end secured to the arm assembly.
Another embodiment of the invention comprises an upright support member, an arm assembly including a horizontal member, and a diagonal brace for movement from a lowered position to an upper storage position. The horizontal member has an upper support roller bearing on a side of the upright support; a lower support roller on an end of the diagonal brace bearing on a side of the support opposite from the upper support roller and a winch on the upright tubular member whereby a flexible belt member wound on a drive pulley of the worm drive winch has an end secured adjacent the upper support roller and the flexible member has indentations to cooperate with teeth on the drive pulley.
In the drawings which illustrate an embodiments of this invention:
FIG. 1 is an exploded perspective view of the display rack of this invention;
FIG. 2 is a side elevational view an arm assembly of the invention of FIG. l;
and FIG, 3 is a side elevational view partly in section of the motor and gear mechanism and FIG. 4 is a top plan view of the motor and winch of Fig. 3.
Referring now in detail to the drawings in which the numeral 10 generally denotes a carpet display rack, the rack 10 has a supporting assembly 12 including posts 14 having bottom plates 18. The posts 14 are also provided with adjustable top plates 22 secured in the adjusted position by set screws 26.
A lower channel plate 30 has spaced apart apertures 32 and a top plate 34 of right angle cross section which has apertures 38 vertically aligned with the apertures 32 of the lower plate 30.
Vertical support members 40 (one of which is shown) have upper and lower pins 44 and 46 adapted to be received in the apertures 34 and 32 respectively for pivotal movement. The pin 44 carries a slidable collar 50 adjustable by means of set screw 52. .
An arm assembly 60 adapted to move vertically on the upright channel member 40, includes a horizontal member 60 and a diagonal brace 64. An associated end 62 of the arm 60 is secured by a bolt 83 to spaced apart plates 65 which engage the upright tubular member 40, and a roller 70 mounted at the end of the horizontal member 60 engages the other side of the tubular member 40. The lower end of the brace 64 is also provided with spaced plates 66 to receive a roller 74 bearing against the adjacent side of the tubular member 40. A roller 86 is also mounted between the plates 65 on the horizontal member 60 adjacent the upright member 40. As illustrated in FIG. 3, a belt 90 extends over a pulley or drum 92 of a winch 94 and has its end 93 looped over fastening means 85 on the horizontal member 60 adjacent the roller 86. The pairs of spaced apart plates 65 and 66 are preferably joined or integrally formed. The pulley or drum 92 has a tooth profile to mesh with that of the belt 90 which is of a type known as a timing chain belt of steel reinforced polymer construction. A standard chain drive is also considered to be a practical alternative.
A nylon roller 100 is provided on the outer end of each arm assembly 60, although means for attaching a carpet to the horizontal member 62 does not form part of this invention, a carpet clip as shown in FIG. 1 grips an upper edge of the carpet. The clip is the subject of another patent by this inventor and is also shown in applicant's United States Patent No.
5,292,011 The gear mechanism 94 is of the type referred to as worm gear and meshes with a gear 124 for rotating the drive pulley drum 92. An electric motor 130 is secured to the shaft 120 to facilitate turning the shaft . A suitable motor is a %2 hp 1800 rpm DC motor manufactured under the trade name Nema .The worm gear. operates at a 50:1 drive ratio and moves a 250 1b load through a 9ft travel in approximately 37 seconds. Worm gears operating at drive ratios of 30:1 or 40:1 may also be selected. The worm gear winch is self braking so that the winch drum cannot accidentally run free.
In use the arm assembly 60 can be raised and lowered, the belt 90 having been correctly installed on the drum 92. The carpet is then secured to the arm assembly 60 through the use of clips and the arm assembly is raised by the electric motor 130 to wind belt 90 on the drum 92. It will be appreciated that if the operator stops the power unit for any reason before fully raising or lowering the arm assembly 60, the drive means cannot run free due to the provision of the self braking winch gear mechanism 94.
