Compliant Railing Bracket

Abstract

A compliant railing bracket system in which useful or decorative items may be attached to various structural members without the use of fasteners, while utilizing a snap-fit method. The design utilizes a geometric configuration such that the bracket encompasses 3 faces of a rectangular structural member utilizing a cantilever snap-lock geometry to engage with the 4.sup.th face creating a secure snap-fit junction. The bracket system may include modular attachment points such as dovetails or come as a pre-formed body with accommodations for various useful items such as flower box brackets, flower pots, solar light mounts, hooks, pegs, rings, tools and utensils.

DETAILED DESCRIPTION

[0028] The inventor provides a unique compliant modular bracket system that is intended to be used in conjunction with common handrails and structural building materials. The new state-of-the-art -shaped system is designed in such a way by geometry and material choice that the bracket will be compliant enough to be manually stretched open and slid over the handrail until the lowermost cantilever snap-locks engage with the bottom of the handrail creating a snap-fit joint with the bottom edge of the structure; yet rigid enough to provide for a structurally sound junction. The present invention is described in enabling detail in the following examples, which may represent more than one embodiment of the present invention.

[0029] FIG. 1 is an elevation view of a more specific version of the compliant railing bracket system being used as a planter box mounting solution. Within the configuration 100, the bracket is fit to a standard wooden 2×4 102. The 101 element acts as a boundary for the planter box to ensure it does not become displaced by the elements. The bracket is designed in such a way either by material choice and/or geometrical thickness, that the center most portion of the geometry 104, which sees the highest bending stress during installation, does not exceed the yield stress of the material and behaves elastically while being installed by the user.

[0030] In this embodiment the user elastically bends the bracket just enough for the cantilever snap-locks 106 to clear the width of the structural member whilst pushing down. The bracket will then slide down around the structural member until finally the latching protrusions clear the bottom most face of the structural member, where the snap-locks will latch into place relieving the bending stress upon 104 and creating a rigid snap-fit junction with the structural member.

[0031] The vertical legs 105 act not only as a boundary to the structural member, but also as a means of preventing tipping motions in the lateral direction as it will experience tensile stresses during such an event due to the engagement of 106. Those experienced in the art would also note that special care must be taken during design to provide an adequate tolerance 103 to accommodate for the slight variations amongst structural members from various regions.

[0032] FIG. 2 is an elevation view of a modular embodiment of the compliant railing bracket system. In this assembly example 200 the bracket still functions in the same manner as 100 with 106 creating a snap-fit junction between the bracket and structural building materials 102, but with the addition of dovetails on each of the three faces 202. The use of dovetails on the bracket 201 allows for a more modular approach in which nearly endless amounts of attachment variations can be mounted with ease. The modular brackets would therefore be unique only in the aspect to the geometries and/or dimensions of the particular structural member in which they were intended.

[0033] FIG. 3 is an elevation view of the installation process for the modular embodiment of the invention. The assembly 300 shows how the bracket 201 should be opened via exerting a moment force upon the bounding vertical cantilever snap-locks until the point in which 106 clears the width of the structural member 102, in which the central dovetail 202 can then be pressed down to where it slides amongst the vertical face of 102 until 106 reaches the bottom and creates a snap fit joint.

[0034] FIG. 4 is a perspective view of modular embodiment of the compliant railing bracket fitted to a standard wooden 2×4. This assembly 400 is an example of the bracket 201 being unique to the structural member 102, which in this case is a standard 2×4.

[0035] FIG. 5 is a perspective view of modular embodiment of the compliant railing bracket fitted to a standard wooden 2×6. This assembly 500 is an example of the bracket 502 being unique to the structural member 501, which in this case is a standard 2×6.

[0036] FIG. 6 is a perspective view of modular embodiment of the compliant railing bracket fitted to a standard wooden 4×4. This assembly 600 is an example of the bracket 601 being unique to the structural member 602, which in this case is a standard 4×4. One can see that having the compliant railing bracket being unique only to the structural member, yet sharing the same dimensional modular attachment points as noted by 202 in FIG. 2; the attachments can all be shared amongst the brackets that vary only in the accommodations for which the structural member they were intended.

[0037] FIG. 7 is an elevation view depicting the use of an attachment for the modular compliant bracket system. The attachment 701 shown in assembly 700 accomplishes the same task as shown in 100, but with the use of the modular embodiment 201 affixed to 102. This alternative approach depicts that nearly unlimited combinations and variations of attachments can be used in conjunction with the modular embodiment 201 allowing the consumer to effectively make use of once unusable square footage.
