Methods of creating bike rack hooks

Abstract

Methods of creating a hook for a bike rack. The methods include the steps of providing a planar metal material, cutting a two-dimensional shape from the planar metal material where the two-dimensional shape defines a hook precursor, forming the hook precursor into a three-dimensional hook where the three-dimensional hook includes a hook face, and adding a protective layer to the hook face. In some examples, the methods include processing the three dimensional hook to remove sharp edges, cutting a mounting point into the hook precursor, cutting a bevel on an edge of the hook precursor to define a beveled edge, and/or cutting a curve on an edge of the hook precursor to define a rounded edge.

Methods of Creating a Hook for a Bike Rack

(14) With reference to the figures, methods of creating a hook for a bike rack will now be described. The methods discussed herein function to produce bike rack hooks.

(15) The reader will appreciate from the figures and description below that the presently disclosed methods address many of the shortcomings of conventional methods of manufacturing bike rack hooks. For example, the methods described below are fast and require less labor than conventional methods. In addition, the presently described methods of creating bike rack hooks do not require multiple materials or specialty materials, but instead utilize sheet material.

(16) Sheet material is affordable, easy to source, easy to store, and convenient to use. By utilizing sheet material, the manufacturing methods described below avoid the drawbacks of three-dimensional source material shapes like rods, blocks, and customized shapes, which tend to be more expensive, harder to maintain and store, and more difficult to process.

(17) The methods discussed below are compatible with rapid and high-volume manufacturing techniques, such as laser cutting, waterjet cutting, stamping, or die processing. Importantly, the novel methods discussed herein avoid the limitations of hand forming materials, bending materials, or extruding materials, which are slow, labor intensive, and expensive.

Method Embodiment One

(18) With reference to FIGS. 1-6, a first example of a method of creating a hook for a bike rack, method 100, will now be described. Method 100 includes the steps of providing a planar metal material at step 101; cutting a two-dimensional shape from the planar metal material at step 102; cutting a mounting point into the hook precursor at step 103; cutting a bevel into the hook precursor at step 104; cutting a curve into the hook precursor at step 105; forming the hook precursor into a three-dimensional hook with a hook face at step 106; removing sharp edges from the three-dimensional hook at step 107; and adding a protective layer to the hook face at step 108.

(19) In some examples, the method does not include one or more steps included in method 100. For example, some manufacturing method examples do not include one or more of cutting a mounting point into the hook precursor; cutting a bevel into the hook precursor; cutting a curve into the hook precursor; removing sharp edges from the three-dimensional hook; and adding a protective layer to the hook face. In other examples, the manufacturing method includes additional or alternative steps.

(20) The reader should understand that the order or steps is not governed by the reference numbers assigned to them in this document. Further, the order of steps may differ in other examples than the order for each step discussed in the examples below.

Providing a Planar Metal Material

(21) With reference to FIG. 1, providing a planar metal material at step 101 allows method 100 to create bike rack hooks faster, easier, and more economically than methods that rely on three-dimensional material stock. In preferred embodiments, the entire structure of the bike hook is formed from a single sheet of metal. In other examples, multiple sheets of metal, such as two or more sheets of metals of different compositions, are used. The dimensions of the planar metal material may be selected to suit given production parameters.

(22) The planar metal material may be any currently known or later developed type of sheet metal. A wide range of metals are suitable, including aluminum, brass, copper, steel, tin, nickel, and titanium. In step 101, the planar metal material consists of a single material, namely sheet metal steel. However, in other examples the planar metal material may comprise multiple materials, which is also referred to as being a composite material.

Cutting a Two-Dimensional Shape to Define a Hook Precursor

(23) Cutting a two-dimensional shape from the planar metal material at step 102 functions to form a hook precursor. An example of a two-dimensional hook precursor is depicted in the middle of FIG. 1 with the reference number 102 pointing to it. Of course, different hook examples will entail different hook precursor shapes, sizes, and configurations than the specific hook precursor depicted in FIG. 1.

(24) The reader can see in FIG. 1 that the two-dimensional hook precursor shape corresponds to a flattened form of the three-dimensional hook depicted at the bottom of FIG. 1 with reference number 106 pointing to it. Subsequent processing of the hook precursor, such as in step 106 described below, forms the three-dimensional hook. Other three-dimensional hooks with different shapes, sizes, and configurations may be formed depending on the particular two-dimensional shape cut from the planar metal material.

(25) One example of step 102 is depicted in FIG. 5. In the FIG. 5 example, cutting a two-dimensional shape from the planar metal material at step 102 includes cutting the planar metal material to define a first hook member at step 1021. This example of step 102 further includes cutting the planar metal material to define a body at step 1022. The example of step 102 depicted in FIG. 5 also includes cutting the planar metal material to define a second hook member at step 1023 and cutting out a portion of the planar material from an interior section of the body at step 1024.

(26) As shown in FIG. 1, the upper geometry of the hook may be different from the bottom geometry to make receiving, releasing, and supporting handlebars easier and more effective. In the example shown in FIG. 1, the upper portion of the three-dimensional hook is flared out relative to the bottom portion of the hook to closely support a handlebar from the front, back, and below when the handlebar is seated in the hook. The flared configuration also facilitates moving the handlebar into and out of the hook.

(27) To achieve these support and movement features, the planar metal material is cut so that the first hook member has a tapered U-shape in step 1021 shown in FIG. 5. Likewise, the planar metal material is cut so that the second hook member has a tapered U-shape in step 1023. As shown in FIG. 1, the tapered U-shape defined by each of the first hook member and the second hook member is selected to complement a handlebar of a bicycle.

(28) In the example depicted in FIG. 5, step 102 includes cutting the first hook member and the second hook member to be mirror images of each other. However, in other examples the planar metal materials cut to form a hook precursor where the first hook member and the second hook member are not mirror images of each other.

(29) In step 1022, the body is cut from the planar metal material such that it is integrally coupled to the first hook member at a first fold line boundary. In the example depicted in FIG. 5, the body is sized to accommodate the head tube of a bike. With the body size selected to accommodate the head tube of a bike, the three-dimensional hook formed in step 106 will have the first and second hook members spaced a distance sufficient for the head tube to extend between them adjacent to the body as the handlebar is supported by the first and second hook members from opposite sides of the head tube.

(30) In step 1023, the second hook member is cut from the planar metal material such that the second hook member is integrally coupled to the body. In particular, the second hook member is disposed opposite the first hook member at a second fold line boundary between the second hook member and the body.

(31) In step 1024, cutting out a portion of the planar material from an interior section of the body functions to reduce the weight of the hook precursor. Cutting out portions of the body may serve aesthetic or other functions as well, such as providing mounting points. However, cutting out a portion of the planar material from an interior section of the body is an optional step not undertaken in all examples. In some examples, portions of the first hook member or the second hook member are cut out in addition to or instead of cutting out portions of the body.

(32) With reference to FIG. 3, the reader can see that cutting a two-dimensional shape from the planar metal material at step 102 may be accomplished in a variety of different ways. For example, step 102 may be accomplished by stamping the planar metal material at step 102A, cutting the planar metal material with a laser at step 102B, or cutting the planar metal material with a water jet at step 102C. Another example of cutting a two-dimensional shape not depicted in FIG. 3 is die processing. Step 102 may be accomplished by any conventional or later developed means for cutting shapes from sheet metal.

(33) CNC machines may be utilized to automate cutting or the cutting tools may be controlled manually. In some examples, the planar metal material is stamped in a manner that both cuts the shape and bevels or rounds the edges of the shape at the same time.

Cutting a Mounting Point into the Hook Precursor

(34) By comparing the planar sheet and the hook precursor in FIG. 1, the reader can see that various defined features may be cut out of the planar material when forming the hook precursor. For example, openings, channels, and mounting points for passing straps, bolts, or fasteners through the bike rack hook and/or to reduce weight or material usage may be cut out of the hook precursor.

(35) As shown in FIG. 2, a mounting point is cut into the hook precursor at step 103. The mounting point may enable safety hold down straps, cords, or other elongate tension bearing members to be secured around a handlebar supported by the three-dimensional hook.

(36) The mounting points may be configured in a variety of shapes and sizes. For example, as depicted in FIG. 1, the mounting point may be round or an open notch channel. Other shapes, such as triangular, square, rectangular, oval, a regular polygon, or an irregular shape are envisioned.

Cutting a Bevel into the Hook Precursor

(37) At step 104 depicted in FIG. 2, cutting a bevel on an edge of the hook precursor defines a beveled edge. Cutting a bevel to form a beveled edge at step 104 may enable the bike rack hook to function more effectively, such as to form inclined surfaces to help guide a handlebar or a strap into a desired position. Additionally or alternatively, cutting a bevel to form a beveled edge at step 104 may contribute to the aesthetics of the bike rack hook.

Cutting a Curve into the Hook Precursor

(38) At step 105 depicted in FIG. 2, cutting a curve on an edge of the hook precursor defines a rounded edge. Cutting a curve to form a rounded edge at step 105 may enable the bike rack hook to function more effectively, such as to reduce friction to help a handlebar or a strap slide over the rounded edge of the three-dimensional hook into a desired position. Forming rounded edges may increase the safety of the three-dimensional hook by removing a sharp edge that could scrape or cut a person's skin or damage a bike. Additionally or alternatively, cutting a curve to form a rounded edge at step 105 may contribute to the aesthetics of the bike rack hook.

Forming the Two-Dimensional Shape into a Three-Dimensional Shape

(39) Forming the hook precursor into a three-dimensional shape at step 106 converts the hook precursor into a functional hook. In the example shown in FIG. 1, the three-dimensional hook is a bike rack hook configured as a double hook. However, the bike rack hook may be configured as a single hook or include more than two hooks.

(40) In one particular example of step 106, the resulting three-dimensional hook includes a first hook member, a body, and a second hook member. The first hook member, the body, and the second hook member correspond to first hook member, the body, and the second hook member formed by cutting the planar metal material in step 102. The body is integrally coupled to the first hook member at a first fold line boundary. The second hook member is integrally coupled to the body opposite the first hook member at a second fold line boundary

(41) The reader can see in FIG. 1 that the three-dimensional shape formed in step 103 corresponds to a hook with hook faces. The hook faces serve as bearing surfaces engaging the handlebar or fork of a bike to retain the bike in position.

(42) Forming the two-dimensional shape into a three-dimensional shape at step 103 may be accomplished by any conventional or later developed means for bending and shaping metal, including sheet metal. The metal forming operations may be accomplished with automated or manual techniques.

(43) One example of steps used to form the hook precursor into a three-dimensional shape at step 106 is shown in FIG. 6. As shown in FIG. 6, forming the hook precursor into a three-dimensional shape at step 106 may include folding the first hook member relative to the body at step 1061. In the example shown in FIG. 6, the first hook member is folded relative to the body at a first fold line boundary.

(44) At step 1062 in FIG. 6, the second hook member is folded relative to the body. In particular, the second hook member is folded relative to the body at a second fold line boundary. In the example shown in FIG. 6, the second hook member is folded relative to the body at step 1062 such at the second hook member is substantially parallel to the first hook member. In other examples, the second hook member is folded relative to the body in a position that is not substantially parallel to the first hook member.

Removing Sharp Edges

(45) Optionally, sharp edges may be removed at step 107. Step 107 may be performed on the nook precursor after cutting the two-dimensional shape at step 102 and/or on the three-dimensional hook after forming the three-dimensional hook at step 106. Removing sharp edges at step 107 may increase the safety of the three-dimensional hook by reducing the chance that contacting the three-dimensional hook will scrape or cut a person's skin or damage a bike. Sharp edges may be removed by any conventional means, such as sanding or polishing.

Adding a Protective Layer

(46) Adding a protective layer to the hook face at step 108 functions to accommodate wear and tear that is likely to occur from inserting and removing the handlebar of a bike from the hook and from supporting the handlebar with the hook. However, adding a protective layer is optional and not all examples of forming a bike rack include a step of adding a protective layer to the face of the hook. As shown in FIG. 4, adding a protective layer to the hook face at step 108 may be accomplished in a variety of ways.

(47) For example, as shown at step 108A, a protective layer may be added by applying a protective coating to the hook face. Additionally or alternatively, as shown at step 108B, adding a protective layer to the hook face may involve attaching a pad to the hook face. The coatings or pads may be any conventional or later developed materials with protective properties suitable for use in a bike rack.

(48) In examples where a pad is applied to the hook faces, the pad may be attached to the hook face by any suitable means. Suitable means include adhering the pad to the face, fastening the pad to the face with a fastener, such as a mechanical fastener or a hook-and-loop fastener, magnetically coupling the pad to the face, or welding the pad to the face.
