Definitions

  • the present invention relates to temporary guardrails and, more particularly, to an apparatus for erecting a temporary guardrail on a stair.
  • stairs particularly of the type in apartment buildings and the like, comprise three major components: stringers, treads and risers, although in certain stair constructions; e.g., pan stairs, there are no risers, open space is being formed between the treads.
  • the stringers can be made of a steel channel beam, wood, etc., the dimensions of which can vary depending upon the load to be carried.
  • the treads are the generally horizontal portions of 15 the stair, while the risers are the vertical portions connecting the treads.
  • US2003/012217 discloses a modular railing system which supports a plurality of rails in a vertically-spaced configuration.
  • the railings are supported by vertical stanchions which may be secured to a stair stringer by means of a C-shaped mounting bracket, and two L-shaped bolts which are turned to press against the inner surface of the C-shaped mounting bracket.
  • TW200839072 discloses a temporary hand rail system for attaching to a staircase, in which the hand rail is supported on a plurality of vertical stanchions which are each spaced from but secured to the staircase stringer by a mounting assembly.
  • US5,314,167 discloses a temporary rail structure that includes a series of vertical interconnected by horizontally extending side rails. Each post is designed to clamp around the top portion of a band that extends around a floor joist that supports a subfloor thereabove.
  • CH590385 discloses a hand rail structure for a staircase which includes a plurality of telescopic vertical stanchions which may be adjusted to vary the height/length of the handrail/stanchion.
  • the stanchions are each provided which a plurality of holes through which a pin may be inserted to set the desired length of the stanchion.
  • US3825098 A discloses a handrail system provided with a clamp with a fixed jaw and a removable J-bolt.
  • One object of the present invention is to provide an assembly for erecting a temporary guardrail on a stair.
  • Another object of the present invention is to provide an apparatus for 5 erecting a temporary guardrail on a stair, which can be quickly assembled and disassembled, as needed.
  • a stanchion or other elongate member first and second, spaced jaws connected to the stanchion, which are adapted to rigidly connect the stanchion to the stringer in such a manner that the stringer is substantially perpendicular to the pitch of the stair.
  • the apparatus of the present invention can further comprise, at least one bracket which can receive a temporary handrail.
  • the apparatus of the present invention shown generally as 10, comprises a metal tubular member or stanchion 12, having a front side 14, a first side 16, a second, opposite side (not shown), and a back side 18 ( Fig. 3 ).
  • a first jaw assembly shown generally as 20 Located generally near the lower end of the stanchion 12 is a first jaw assembly shown generally as 20, a second jaw assembly shown generally as 22 being spaced longitudinally from first jaw assembly 20 in a direction toward the upper end of stanchion 12.
  • Bottom jaw assembly 20 comprises an L-shaped head portion having a flange portion 24 and a leg portion 26 attached thereto, a threaded shank 28 extending from leg portion 26 and through registering bores 31 and 30 in the front and back sides 14 and 18, respectively.
  • a wing nut 32 is threadedly received on the portion of shank portion 28 extending out of bore 30, a washer 34 being positioned between wing nut 32 and back surface 18.
  • threaded shank 28 and wing nut 32 comprise a compression assembly for a purpose described hereafter.
  • Second jaw assembly 22 also comprises an L-shaped head portion having a flange portion 36, a leg portion 38, a threaded shank portion 40 extending from leg portion 38 through registering bores 42 and 43 in stanchion 12.
  • a wing nut 44 is threadedly received on the portion of threaded shank 40 extending through back side 18 of stanchion 18.
  • stanchion 12 has a plurality of registering bores 42 and 43, through which threaded shank 40 can extend to allow jaw assembly 22 to be adjustable longitudinally along stanchion 12.
  • a channel shaped spacer 60 effectively a washer, can be used, the spacer 60 overlying the plurality of bores on the back side 18 of stanchion 12.
  • Fig. 5 is a cross-sectional view taken along the lines 5-5 of Fig. 4 and accordingly, shows a portion of a stair assembly.
  • the stair assembly comprises treads 46 and risers 48, which are attached in a suitable fashion to stringers 50, 52 which support the stair.
  • stringers 50, 52 which support the stair.
  • the detailed construction of only one of the stringers of the apparatus of the present invention will be described.
  • a stair with two stringers is shown, it will be apparent that many stairs are constructed against a wall so that only one stringer would have a guardrail.
  • the stairs shown have risers, as noted above, in the case of pan stairs there are no risers.
  • Fig. 5 is a cross-sectional view taken along the lines 5-5 of Fig. 4 and accordingly, shows a portion of a stair assembly.
  • the stair assembly comprises treads 46 and risers 48, which are attached in a suitable fashion to stringers 50, 52 which support the stair.
  • the stringers 50, 52 act as side supports for the stair and are generally at the desired pitch of the stairs.
  • Stringer 50 comprises a channel shaped metal beam, having a main beam portion 52 and spaced, laterally extending flanges 54 and 56. As can be seen in Fig. 5 , flanges 54 and 56 space beam portion 52 from stanchion 12. It will be appreciated that the stringer 50 need not be channel-shaped but could be a square tubular member, a wooden beam, etc., but in any event, would have a surface 58 spaced from stanchion 12.
  • stringer 50 is received between first and second jaw assemblies 20 and 22, such that flange portion 24 abuts the side 58 of stringer beam portion 54 adjacent flange portion 56. Further, when so positioned, it can be seen that by tightening wing nuts 32 and 44, flanges 24 and 36, respectively, will urge stanchion 18 toward stringer 50, stanchion 12 being compressed against the outer edges of flanges 54 and 56 of stringer 50, thereby rigidly securing stanchion 12 to stringer 50.
  • brackets 70 and 72 which are affixed to stanchion 12 by means of bolts 74 and 76, respectively, which extend through registering bores 80, 82 in the front side 14 and back side 18 of stanchion 12.
  • brackets 70 and 72 are shown as tubular, they could be L-shaped in construction or for that matter, any other form, the only proviso being that they be adapted to support a temporary guardrail; e.g., a 2 X 4.
  • 2 X4 temporary rails 84 and 86 are received in brackets 70 and 72, respectively, the rails being secured to the brackets 70 and 72 by fasteners 90 and 92; e.g., a screw, nail or the like, extending through holes 78, 79 of brackets 70, 72, respectively.
  • Threaded wing nuts 75 and 77 are received on bolts 74 and 76, respectively, to secure brackets 70 and 72, respectively, to stanchion 12.
  • jaws 20, 22 and brackets 70 and 72 are rotatable with respect to stanchion 12, such that they can be disposed at any desired angle, if necessary, to accommodate and provide rails which are at any desired angle.
  • the guardrails are at an angle the same as the angle of the pitch line of the stair, as shown in Fig. 4 .
  • brackets 70 and 72 can be longitudinally adjusted along stanchion 12 by virtue of a plurality of registering bores, such as 80 and 82.
