Description

    BACKGROUND OF THE INVENTION
  • (1) Field of the Invention
  • The present invention relates generally to handrails and, more particularly, to a handrail with at least two segments joined by a hidden fastener.
  • (2) Description of the Prior Art
  • In stairway systems aesthetics and ease of construction are very important. This applies not only to treads, balusters and newels of a stairway system, but also to the handrail as well. Currently, handrail segments are attached by several different methods, each of which entails several disadvantages.
  • One such method involves boring, at an angle, two large holes through two segments of a handrail. The shorter, smaller hole serves to countersink a bolt that is placed in the hole in order to join the two segments. At the other end of the hole drilled in the second segment of the handrail, a nut is placed on the end of the bolt. Hand tools are then used in order to tighten the nut and bolt assembly, thus securing the two segments of the handrail. When this is complete a wooden cap, of the same diameter as the hole, must then be secured at the end of the drilled hole on each segment in order to close the vacancy. This process, however, has proven to be rather cumbersome. First, it is very time consuming and wearisome because of the multiple procedures that must occur. Furthermore, when the process is complete the handrail is aesthetically imperfect because of the capped segments, which disrupt the otherwise continuous grain of the wood. These two disadvantages combine for a less than ideal process for joining members of a handrail.
  • While a second method of connecting handrails has proven more aesthetically pleasing, another disadvantage emerges. This method involves manufacturing a rail consisting of a body and a cap. The cap of the rail is generally a long, rectangular top piece, which covers a cavity in the body of the rail when placed into position. Meanwhile, the body of the rail includes a large cavity as well as a hole for the placement of a bolt. Placing the bolt into the hole, tightening the bolt, and attaching the large cap segment of the rail to the body assemble the rail. The large cavity in the body serves to allow the assembler to more easily tighten the bolt. This process, however, is also much less than ideal. Again, the process is quite time-consuming and the rail is still fairly difficult to assemble. Furthermore, while the rail is more aesthetically pleasing because of the large rectangular cap rather than a small circular one, the cap and body approach still leaves a rail without matching grains. In other words, the continuity of the wood is lost.
  • Thus, there remains a need for a stairway and rail system that may be easily installed in a timely fashion and may be constructed in such a way so as to maintain the continuity of the rail segments by utilizing hidden fasteners.
  • SUMMARY OF THE INVENTION

Also in the preferred embodiment, the stairway system comprises a lateral support for supporting the handrail.
  • The present invention is further directed to a system for joining a handrail having at least two segments, the system comprising: a fixed position portion of a fixture, the fixed position portion having a pair of opposing generally parallel surfaces extending downwardly and having a distance there between for inserting a segment of the handrail, wherein the distance between the surfaces decreases along at least a portion of the downwardly extending opposing surfaces; an adjustable portion of a fixture, the adjustable portion attached to the fixed position portion and movable with respect to the fixed position portion, the adjustable portion having a pair of opposing generally parallel surfaces extending upwardly and having a distance there between for inserting a segment of the handrail, wherein the distance between the surfaces decreases along at least a portion of the upwardly extending opposing surfaces; a selectively movable hole positioner attached to the fixed position portion of the fixture and comprising a stop and at least one hole guide, the hole positioner for determining a position for boring at least one hole in a segment of the handrail.

The assembler may then bore a hole into the segment 15 and fasten the fixture to the segment. In the preferred method, this would be done by inserting a screw into the newly bored hole with the use of the hole positioner. The assembler may then bore an additional hole in the segment 15 for inserting a hidden fastener. The assembler may repeat the above method steps with another segment 15. This may be a segment 15 of the same or a different cross-sectional profile. It is especially effective to use a single fixture capable of positioning holes in handrails having different cross-sectional profiles. This type of fixture is described above and its capability of use with handrails having differing cross-sectional profiles illustrated in FIG. 4.
  • A joining element may be placed in one or both of the holes in the segment 15. The joining element may be a joining element made by INVIS®. A structure meant to prevent rotation may be attached to a segment 15. This structure may be inserted into one of the bored holes in the segment 15 and may comprise a dowel. Adhesive may also be a structure meant to prevent rotation or may be an addition to the structure. Joining the hidden fasteners may then join the segments of the handrail. This may be accomplished by means of an actuator. The actuator may be an INVIS® actuator also available from Invis North America, Inc. of Irvin, Calif. which is a subsidiary of Lamello AG, CH. The method of joining the segments of a handrail may be done for handrails of differing cross-sectional profiles.
  • Certain modifications and improvements will occur to those skilled in the art upon a reading of the foregoing description. By way of example, while in the preferred embodiment, both the hidden fastener and structure for preventing rotation are about the same diameter, this is a matter of convenience to the installer and other sizes could be substituted. It should be understood that all such modifications and improvements have been deleted herein for the sake of conciseness and readability but are properly within the scope of the following claims.
