Definitions

  • This invention relates to a bracket for installing the top rail of a handrail on a support portion at an installation area such as a staircase, floor or the like, for example. More particularly, this invention relates to a bracket which firmly and easily attaches the top rail of a handrail formed of resilient material such as soft synthetic resin, semi-hard synthetic resin of synthetic rubber and having a metal core or cores embedded therein to the support portion. More particularly, this invention relates to a bracket for use with the top rail of a handrail which enables the top rail of a handrail to be easily attached to a support portion with a required slope and which will not stand in the way when the user slides his hand or hands along the top rail.
  • brackets for use with the top rails of handrails of the above-mentioned type have been proposed and practically employed.
  • One of such prior art brackets is a cantilever type bracket having the arrangement in which one end of the support arm is secured to a wall by a screw or screws and the other end of the support arm is attached to the top rail of a handrail to support the top rail and the handrail top rail is formed of a metal pipe with high rigidity. Therefore, there is scarcely the possibility that the pipe span between a pair of adjacent brackets bends to apply a load to the support arm or top rail which load tends to rotate the support arm, and instead the handrail top rail prevents the application of such force to the bracket support arm.
  • handrail top rails are in most case formed of various materials and especially resilient materials at present, when a load is applied to the top rail span between a pair of adjacent brackets, the top rail span bends somewhat to apply a load to the support arms of the brackets so as to rotate the brackets.
  • the screws which secure the brackets to a supporting wall become loose and as a result, the brackets come loose with respect to the wall. In the worst case, the brackets fall off the wall.
  • bracket when the bracket is formed as a split type bracket comprising components separate from each other and assembled together by connector means so that the bracket may accommodate the slope with which the top rail is installed, after a prolonged service or use, the connector means tend to become loose resulting in insufficient supporting of the top rail by the bracket.
  • the handrail top rail comprises a body formed of resilient material such as soft synthetic resin, semi-hard synthetic resin or synthetic rubber and a metal core or cores embedded in the body, even if the top rail is secured by the use of a screw or screws to the bracket secured to a wall, when a load is applied to a top rail, the top rail tends to deform at its secured point or points and comes loose because the body of the top rail and its coating are firmed of resilient material.
  • top rail body is formed of resilient material
  • an impact applied to the top rail span between a pair of adjacent brackets causes the handrail top rail to oscillate and as a result, after a prolonged service or use, a problem arises in connection with means which firmly secures the handrail top rail to a wall against the resilience of the surface of the top rail.
  • the object of the present invention is to provide a bracket for use with the top rail of a handrail which firmly secures a handrail top rail comprising a body formed of resilient material such as soft synthetic resin, semi-hard symetric resin or synthetic rubber and a metal core or cores embedded in the body at an installation area such as a staircase or floor extending from one end to the other and of the installation area with freedom of bending a without joints.
  • a bracket for use with the top rail of a handrail which firmly secures a handrail top rail comprising a body formed of resilient material such as soft synthetic resin, semi-hard symetric resin or synthetic rubber and a metal core or cores embedded in the body at an installation area such as a staircase or floor extending from one end to the other and of the installation area with freedom of bending a without joints.
  • Another object of the present invention is to provide a bracket for use with the top rail of a handrail which firmly secures the top rail at an installation area, which easily accommodates the slope with which the top rail is installed and which resists loosening and ratting caused by the loosening after a prolonged service or use.
  • a still further object of the present invention is to provide a bracket for use with the top rail of a handrail which is simpler in construction and less expensive and which installs the top rail in a simpler and easier operation in a relatively short time period.
  • a bracket for use with the top rail of a handrail which comprises a mounting block adapted to be secured to a support portion at an installation area, a support arm extending outwardly from the block and a top rail support member provided at the leading end of the support arm and including a top rail receiving groove of substantially U-shaped cross-section.
  • a handrail top rail comprising a body formed of resilient material such as soft synthetic resin, semi-hard synthetic resin or synthetic rubber and a metal core or cores embedded in the body can be installed at an installation area with the winding in conformity with the contour of the installation area and extending from one end to the other end of the installation area without joints in a simpler manner at less expense.
  • the bracket is simpler in construction and less expensive, simplifies the top rail installation operation and shortens the installation time.
  • the bracket can be colored in various colors to enhance decorative effect of the top rail.
  • the bracket includes a top rail support block separate from and secured to a support arm by connector means and having a top rail receiving groove and a boss.
  • the top rail support block is firmly connected to the support arm so as to reinforce the support arm by the connector means whereby even when the top rail span between adjacent brackets in pair bends to apply a load to the support arm to cause the support arm to rotate, the connection between the support arm and top rail support block provided by the connector means will not come loose and the top rail can be positively secured to a wall at a predetermined installation angle to the wall.
  • the bracket of the present invention comprises a relatively small number of components, that is, three components such as the support arm having the integrally formed flange, the top rail support block and connector means. Furthermore, since the connection angle between the support arm and top rail support block can be freely adjusted, the bracket can accommodate different slopes with which the top rail is installed at the installation area and is suitable to mass production.
  • the bracket of the invention is advantageously employed in the application where the handrail top rail is formed of resilient material and secured to the wall by a relatively large number of brackets.
  • the bracket when the mounting portion partially defining the top rail receiving groove or both the mounting portion and the upright arm which defines the top rail receiving groove in cooperation with the opposing mounting portion extending along the inner or outer side of the top rail, the bracket will not be in the way when the user slides his hand or hands along the top rail and when the mounting portion is positioned on the inner side of the top rail, the securing means such as screws are not exposed on the outer side of the handrail top rail.
  • the bracket mounting structure effectively prevents the rotation (rolling) of the top rail due to elastic deformation of the surface of the top rail because the top rail formed of resilient material such as soft synthetic resin, semi-hard synthetic resin or synthetic rubber is received in the top rail receiving groove of substantially U-shaped cross-section partially defined by the mounting portion and held in position by the securing means such as screws extending through the mounting portion whereby the connection between the top rail and top rail receiving groove is substantially reinforced and the handrail top rail can be attached to the wall under substantially increased stabilized conditions.
  • resilient material such as soft synthetic resin, semi-hard synthetic resin or synthetic rubber
  • the connection between the top rail receiving groove and top rail is further reinforced. Furthermore, when the top rail is fitted in the bracket top rail receiving groove with slight elastic deformation by the utilization of the resilient material of the top rail, the bracket can be temporarily secured to the top rail prior to the securing of the bracket to the top rail whereby the top rail receiving groove can be quite easily positioned with respect to the top rail. Especially, when a single top rail is installed at the installation area from one end to the other end of the installation area without joints while being bent, the installation operation can be performed easily and thus, the bracket of the invention is a quite suitable installation construction for bendable handrail top rails.
  • Figs. 1 and 2 the first embodiment of bracket B for use in connection with handrail top rails embodying the present invention is shown.
  • the bracket B comprises a mounting block 1 adapted to be secured to a support portion at the installation area or a wall W by means of screws 7 or the like, a support arm 2 extending outwardly from the block 1 substantially at right angles thereto and a top rail support member 3 formed at the leading end of the arm 2.
  • the top rail support member 3 includes a top rail receiving groove 8 of substantially U-shaped cross-section defined by a pair of opposite and spaced arms 3a, 3b shaped in conformity with the contour of the surface of a lower portion of a handrail top rail H. As shown in Fig.
  • the top rail H which is adapted to be secured to the installation area t or wall W adjacent a staircase, floor or the like by the bracket B comprises an elliptical cross-section body 5 formed of resilient material such as soft synthetic resin, semi-hard synthetic resin or synthetic rubber.
  • the top rail body 5 has two bendable metal cores 6 incorporated therein and the cores are capable of maintaining the body 5 in its bent condition against the resiliency of the top rail body 5 after the top rail has been bent.
  • the top rail is bent in conformity with the winding contour of the wall W adjacent the staircase and the grooves 8 in the top rail support members 3 of a plurality of brackets B are fitted on the top rail H at spaced points along the length of the top rail.
  • screws 7 are driven from the inner or back side of the top rail H into the support members 3 to firmly hold the top rail H in the support members 3 and screws 7 are driven from the outer sides of the blocks 1 of the brackets B to secure the top rail and bracket assembly to the walls W.
  • the upper edges of the opposite arms 3a, 3b of the top rail support members 3 extend to substantially the center of the height of the top rail H on the outer and inner sides of the top rail, respectively and the distance between the leading or upper end portions of the arms 3a, 3b is slightly smaller than the width of the top rail H (the distance between the outer and inner sides of the top rail) so that when the top rail support member 3 is fitted on the top rail H, the top rail body 5 is caused to deform by virtue of its resiliency whereby the top rail H is tightly fitted in the groove 8 of the top rail support member 3 against inadvertent rotation (rolling) within the groove 8 which otherwise occurs due to the deformation of the resilient top rail when a load is applied to the top rail.
  • the screws 7 driven through the support member 3 into the top rail body are disposed substantially normal with respect to the arms 3a, 3b of the support member 3 (that is, substantially in the horizon) so that the screws 7 resist positively a load which will be applied to the top rail H in the direction in which the top rail comes out of the support member groove 8 (that is, in the vertically upward direction).
  • the second embodiment of bracket B as shown in Figs. 3 and 4 is different from the first embodiment with respect to the construction and attaching mode of the top rail support member 3 in that the support member 3 has a L-shaped cross-section and includes a shorter outer arm 3a and a longer inner arm 3b the upper edge of which extend! to a position adjacent the upper edge of the top rail H to form a mounting portion 4 and screws 7 are driven from the back side of the longer arm 3b through the arm into the top rail H to secure the top rail and bracket together.
  • the entire mounting portion 4 is also shaped in conformity of the contour of the back side of the top rail H so that the mounting portion 4 will not be in the way when the user slides his hand or hands along the top rail H.
  • the longer arm 3b or mounting portion 4 has a larger contact area with respec .
  • the screws 7 to be screwed into the top rail H can be disposed in two upper and lower rows to thereby connect the top rail and top rail support member together more firmly.

  • a plurality of the modified brackets B are first secured to the walls at suitably spaced points along the walls, the top rail H is fitted in the grooves 8 in the top rail support members 3 of the brackets B while being bent in conformity with the contour of the walls and screws are driven through the longer or outer arms 3a into the top rail H to secure the top rail H to the mounting portions 4 of the brackets B in a simpler manner. Since the upper edges of the mounting portions 4 extend to a position adjacent the upper edge of the outer side of the top rail, the brackets resist more positively a load applied to the top rail H in the outward direction of the top rail.
  • Figs. 6 and 7 show a further modification of the second embodiment of bracket and in this modification, as in the embodiment as shown in Figs. 3 and 4, the inner arm 3b of the top rail support member 3 which defines the inner wall of the groove 8 is formed as the mounting portion 4.
