Stages are often used in the entertainment industry and may be platforms or other areas where a performer may perform an act, such as a live theater play, a musical recital, a lecture, or other performance for entertainment or informational purposes. Modern stages are designed to provide an audience positioned around the stage with a clear view of a performer on the stage. In addition, stages may have associated peripheral devices mounted on various support member above and around the stage to generate effects to enhance the performance carried out on stage. Such peripheral devices may include lighting fixtures as well as speakers and other devices such as pyrotechnic equipment, fog machines, mirrors, and other props.
Reference will now be made, by way of example only, to the accompanying drawings in which:
As used herein, any usage of terms that suggest an absolute orientation (e.g. “top”, “bottom”, “up”, “down”, “left”, “right”, etc.) may be for illustrative convenience and refer to the orientation shown in a particular figure. However, such terms are not to be construed in a limiting sense as it is contemplated that various components will, in practice, be utilized in orientations that are the same as, or different than those described or shown.
Modern stages for performances, such as plays, concerts or lectures, may use multiple devices to provide sound and visual effects for the performance. Sound effects may include generating background music, or amplifying sound from on the stage. Visual effects may include lighting and laser effects. Additional effects such as pyrotechnic displays and fog machines may be also used. Some of the equipment used to provide the sound and visual effects are to be positioned above and beside the stage to improve the generated effect. For example, a light or laser source may be positioned above the stage so that light may be directed at the stage during a performance from above to achieve an appropriate lighting effect.
Equipment positioned above or around a stage may be placed at a specific location based on a set design for the performance. In addition, the equipment may be placed at a position above the stage at varying heights and at relative positions. In order to mount and secure equipment above a stage or near a stage, a support member, such as a truss, may be positioned above the stage. The support member may be part of a structure that is to be built above and around the stage from which various pieces of equipment may be mounted. The complexity of such a structure is not particularly limited and may involve assembling and connecting multiple support members. For example, the structure may include a single support member spanning across a stage secured to a wall or other existing structure. The support member may be positioned at a fixed location above the stage in such examples. Furthermore, the structure may include multiple connected support members in different positions and orientations to provide greater flexibility on the amount an positioning of equipment about and above the stage.
Many performances performed on a stage move from venue to venue. Accordingly, the structure used to support the equipment may be assembled and disassembled frequently and moved from venue to venue with the performance. In other examples, the structure may be leased or rented to different events such that the structure is to be disassembled between each performance. Once disassembled, the structure may include multiple pieces to be transported together. In order to efficient transport the pieces, the pieces are often organized and stacked together in order to increase the efficient of space occupied.
A support member capable of stacking other support members thereon is provided. The support member includes stacking guides to guide a second support member to a position above the original support member. For example, if multiple support members have substantially similar dimensions, or share a dimension, such as a width and/or length, the support member may be used to align additional support members placed above. By aligning the support members as they are stacked, the use of space may be more efficient to allow more support members to be placed within a confined space, such as in a shipping container or transport truck.

In the present example, the elongated member 20-1 is disposed proximate to an edge of the structure of the support member 10. The elongated member 20-1 is generally shaped with a substantially flat surface on the top as illustrated in the figures. It is to be appreciated by a person of skill in the art with the benefit of this description that the top surface of the elongated member 20-1 may be used to interact with a portion of another support member to be stacked thereon. In the present example, it is contemplated that the second support member is includes an elongated structure similar to the rigid structure of the support member 10. Accordingly, the flat surface of the elongated member 20-1 may provide stability for stacking by supporting the additional support member. It is to be appreciated that in other examples, the elongated member 20-1 may have other shapes, such as a curved surface on top.
The support member 10 further includes the elongated member 25-1 disposed proximate to an opposite edge of the rigid structure of the support member 10. In the present example, the elongated member 20-1 and the elongated member 25-1 are at opposite lengthwise ends as shown in
In the present example, the elongated member 20-1 and the elongated member 25-1 are positioned to engage the rigid structure of another support member of similar size placed thereon. As there are at least two points of contact, one on the elongated member 20-1 and the other on the elongated member 25-1, the weight of the additional support member placed above the support member 10 may be distributed among different points on the support member 10. Therefore, the stress on each of the elongated member 20-1 and the elongated member 25-1 is reduced. Furthermore, additional contact may also be made with the elongated members 15-1 and 15-2 with corresponding members of the rigid structure of the additional support member placed above.
The stacking guide 30 is to be disposed on the elongated member 20-1. The stacking guide 30 is not particularly limited and it is to be appreciated that different mechanisms and designs are contemplated. In general, the stacking guide 30 is to guide an attachment point of the second elongated rigid structure to be positioned above the support member 10 such that an end of the support member placed above may be substantially aligned in the proximity of the stacking guide 30. The manner by which the stacking guide 30 guides the additional support member is not particularly limited. In the present example, the stacking guide 30 may have a top surface slope toward the surface of the elongated member 20-1. Accordingly, in this example, the slope may be designed to position a protrusion or boss on the rigid structure of another support member with gravity. In particular, the stacking guide 30 may be a ring and the slope may guide the protrusion or boss to the center of the ring. In other examples, the stacking guide 30 may use other mechanisms, such as magnetic or electromagnetic forces, to position the rigid structure of the support member placed above the support member 10.

As shown in
In the present example, the stacking guide 30 is to be made from a substantially hard material that is not easily deformed by the weight of the additional support member placed above support member 10. It is to be appreciated by a person of skill with the benefit of this description that the stacking guide 30 is not limited to any specific type of material and that several different types of materials are contemplated. In general, the stacking guide 30 is to be sufficiently hard and rigid to withstand lateral forces such that the stacking guide 30 may prevent lateral movement of the protrusion or boss resting within the boundaries of the stacking guide 30. The materials from which the stacking guide 30 may be made include metal, such as steel or aluminum, wood, plastic, or composite materials. In some examples, the stacking guide 30 may include a combination of different types of materials.
The stacking guide 35 is to be disposed on the elongated member 25-1 at the opposite end of the rigid structure from the stacking guide 30. The stacking guide 35 may be substantially similar to the stacking guide 30. In other examples, the stacking guide 35 may be different from the stacking guide 30. In general, the stacking guide 35 is to guide another attachment point of the second elongated rigid structure to be positioned above the support member 10 such that the support member placed above may be substantially aligned. The manner by which the stacking guide 35 guides the additional support member is not particularly limited and may be operate in a similar manner as the stacking guide 30. For example, the stacking guide 35 may similarly have a top surface slope toward the surface of the elongated member 25-1. The slope may be designed to position a second protrusion or boss on the rigid structure of the support member placed above the support member 10 with gravity. In other examples, the stacking guide 35 may use magnetic or electromagnetic forces to position the rigid structure of the support member placed above the support member 10.
Similar to the stacking guide 30, the stacking guide 35 is to be made from a substantially hard material that is not easily deformed by the weight of the additional support member placed above support member 10. It is to be appreciated by a person of skill with the benefit of this description that the stacking guide 35 is not limited to any specific type of material and that several different types of materials are contemplated such as the materials discussed above in connection with the stacking guide 30.
Although the present example contemplates stacking substantially a similar sized support member directly on top of the support member 10, it is to be appreciated by a person of skill with the benefit of this description that it is not limited. For example, other stacking configurations are contemplated there support members may be staggered or stacked perpendicularly in adjacent layers. In other examples, the support members may also be of different lengths such that the ends of the support members may not line up.

In the present example, the support member 50 includes a plurality of elongated members 55-1, 55-2, 55-3, 55-4 (generically, these elongated members are referred to herein as “elongated member 55”, and collectively they are referred to as “elongated members 55”, this nomenclature is used elsewhere in this description), another plurality of elongated members 60-1, 60-2, 60-3, 60-4 (generically, these elongated members are referred to herein as “elongated member 60”, and collectively they are referred to as “elongated members 60”, this nomenclature is used elsewhere in this description), another plurality of elongated members 65-1, 65-2, 65-3, 65-4 (generically, these elongated members are referred to herein as “elongated member 65”, and collectively they are referred to as “elongated members 65”, this nomenclature is used elsewhere in this description), and attachment points 70 and 75.
The elongated members 55, 60, and 65 are used to provide a structure to support equipment at a predetermined position above or beside a stage and function similar to the elongated members 15, 20, and 25 of the support member 10 to form a rigid structure. In the present example, the rigid structure formed by the elongated members 55, 60, and 65 may be substantially identical in structure to that of the support member 10. Accordingly, when deployed above a stage, the support member 50 may be interchangeable with the support member 10 in some case. In other examples, the support member 50 may include additional elongated members or features to accommodate specialized equipment. It is to be appreciated by a person of skill in the art with the benefit of this description that the rigid structure of the support member 50 is not particularly limited and may be one of many different configurations depending on the weight of equipment to be supported as well as the complexity of the overall structure above the stage.
In the present example, the elongated member 60-3 is disposed proximate to an edge of the structure of the support member 50. The elongated member 60-3 is generally shaped with a substantially flat surface on the bottom of the support member 50. It is to be appreciated by a person of skill in the art with the benefit of this description that the bottom surface of the elongated member 60-3 may be used to interact with the top surface of the elongated member 20-1 of the support member 10. Although the elongated member 60-3 includes a flat bottom surface in the present example, it is to be appreciated that in other examples, the elongated member 60-3 may have a curved surface or irregularly shaped surface on the bottom.
The support member 50 further includes the elongated member 65-3 disposed proximate to an opposite edge of the rigid structure of the support member 50. In the present example, the elongated member 60-3 and the elongated member 65-3 are at opposite lengthwise ends. Similar to the elongated member 60-3, the elongated member 65-3 is generally shaped with a substantially flat surface on the bottom. It is to be appreciated by a person of skill in the art with the benefit of this description that the bottom surface of the elongated member 65-3 may be used to interact with the top surface of the elongated member 25-1 of the support member 10.
As there are at least two points of contact, one between the elongated member 60-3 and the elongated member 20-1 and the other between the elongated member 65-3 and the elongated member 25-1, the weight of the support member 50 placed above the support member 10 may be distributed between the two points to reduce the stress on each of the elongated member 20-1 and the elongated member 25-1. Furthermore, additional contact may also be made with the elongated members 15-1 and 15-2 with elongated members 55-4 and 55-3 of the support member 50, respectively.
The attachment point 70 is to be disposed on the bottom of the elongated member 60-3. The attachment point 70 is not particularly limited and various mechanisms and designs to mate with the stacking guide 30 are contemplated. In the present example, the stacking guide 30 may have a top surface slope toward the surface of the elongated member 20-1. The slope may be designed to position the attachment point 70 of the support member 50 with gravity. In particular, the attachment point 70 is a protrusion extending from the bottom surface of the elongated member 65-3 such that once the attachment point 70 passes the highest point of the stacking guide 30, the attachment point 70 is guided to a centered position within the boundaries of the stacking guide 30.
In the present example, the attachment point 70 is to be made from a substantially hard material that is not easily deformed by the weight of the support member 10. In the present example, the attachment point 70 may be made from the same materials as the stacking guide 30 discussed above. It is to be appreciated by a person of skill with the benefit of this description that the stacking guide 30 and the attachment point 70 may be interchanged in some examples. In the present example, the stacking guide 30 is a closed shape, such as an oval shaped ring, into which the attachment point 70 fits. Accordingly, the oval shaped ring is to hold the attachment point 70 in place to restrict lateral movement. In other examples, the attachment point 70 may be a closed shape into which the stacking guide 30 fits.
The attachment point 75 is to be disposed on the elongated member 65-3 at the opposite end of the rigid structure from the attachment point 70. The attachment point 75 may be substantially similar to the attachment point 70. In other examples, the attachment point 75 may be different from the attachment point 70. In general, the attachment point 75 is to interact and mate with the stacking guide 35 of the support member 10 such that the support member 50 may be substantially aligned above the support member 10. The manner by which the attachment point 75 interacts with the stacking guide 35 is not particularly limited and may be similar to the manner by which the attachment point 70 interacts with the stacking guide 30.
Similar to the attachment point 70, the attachment point 75 is to be made from a substantially hard material that is not easily deformed by the weight of the support member 50 placed above support member 10. It is to be appreciated by a person of skill with the benefit of this description that the attachment point 75 is not limited to any specific type of material and that several different types of materials are contemplated such as the materials discussed above in connection with the attachment point 70.
In the present example, as the attachment point 70 and the attachment point 75 approach the stacking guide 30 and the stacking guide 35, respectively, the stacking guide 30 is to guide the attachment point 70 to a predetermined location, and the stacking guide 35 is to guide the attachment point 75 to another predetermined location. It is to be appreciated that the predetermined locations to which the attachment point 70 and the attachment point 75 are guided is not particularly limited. In this example, the predetermined locations are selected to align the support member 50 substantially directly over the support member 10.
In the present example, the stacking guide 30 and the stacking guide 35 may be shaped to mate with the attachment point 70 and the attachment point 75. The stacking guide 30 and the stacking guide 35 are substantially similar oval shaped rings and the attachment point 70 and the attachment point 75 are substantially similar oval shaped protrusions with dimensions to fit within the stacking guide 30 and the stacking guide 35, respectively. Accordingly the weight of the support member 50 may cause the stacking guide 30 and the stacking guide 35 to guide the attachment point 70 and the attachment point 75, respectively, to the center of the oval shaped rings. It is to be appreciated that the stacking guide 30 and the stacking guide 35 are not particularly limited by shape. In other examples, instead of being closed ovals, the stacking guide 30 and the stacking guide 35 may be open shapes to confine the movement of the attachment point 70 and the attachment point 75, respectively, by contacting opposite ends of the protrusions. In other examples, the shape of the stacking guide 30 and the stacking guide 35 may be another shape to mate with the attachment point 70 and the attachment point 75.

It is to be appreciated by a person of skill in the art with the benefit of this description that the elongated members 15a, 20a, 21a, 22a, 24a, 25a, 26a, and 28a are connected to form a truss structure. In particular, the elongated members 15a, 20a, 21a, 22a, 24a, 25a, 26a, and 28a provide the support member 10a with rigidity such that heavy equipment may be attached at a location above or near the stage. In the present example, the elongated members 15a, 20a, 21a, 22a, 24a, 25a, 26a, and 28a are not particularly limited and may be each substantially similar. In other examples, some of the elongated members 15a, 20a, 21a, 22a, 24a, 25a, 26a, and 28a may be different sizes and/or made from different materials depending on the expected load. Furthermore, the truss structure of the support member 10a may be modified to add addition elongated members to increase the structural rigidity. Similarly, the truss structure of the support member 10a may be modified to omit some of the elongated members to simplify the design and assembly process.
Referring to
In the present example, the stacking guide 30a is different from the stacking guide 35a. The stacking guide 30a is to mate with the attachment point 70a. Similarly, the stacking guide 35a is to mate with the attachment point 75a. Accordingly, the stacking guide 30a is to be incompatible with the attachment point 75a and the stacking guide 35a is to be incompatible with the attachment point 70a. Therefore, in examples where the support member 50a includes no additional attachment points, the stacking guide 30a and the stacking guide 35a permit the structure of the support member 50a to be aligned with the support member 10a in a single orientation.
The stacking guide 30a may be substantially similar to the stacking guide 30 describe above. In particular, stacking guide 30a may be an oval shaped ring and the attachment point 70a may be a substantially similar oval shaped protrusion with dimensions to fit within the stacking guide 30a. The stacking guide 35a may be a substantially oval shaped protrusion and the attachment point 75a may be a substantially similar oval shaped ring with dimensions to fit around the stacking guide 30a. It is to be appreciated that the stacking guide 30a may be substantially similar to the attachment point 75a and the stacking guide 35a may be substantially similar to the attachment point 70a. In other examples, the shape of the stacking guide 30a and the stacking guide 35a may be other shapes to mate with the attachment point 70a and the attachment point 75a, respectively, each having a different, but complementary shape.
Accordingly, the support members 10a and 50a may be designed to accommodate a specific stacking order. For example, the support member 10a and the support member 50a may include features, such as a mounting point for equipment or pre-mounted with equipment that may use space such that the support member 50a is to be stacked in an orientation that may accommodate equipment protruding from the support member 10a and vice versa. In addition, the stacking orientation may also be used to facilitate assembly in examples where the support members are to be assembled in a specific orientation by having the support member 50a oriented in the correct manner to avoid flipping the support member 50a prior to assembly.

In the present example, the support member 10a includes stacking guides 30b-1 and 30b-2 (generically, these elongated members are referred to herein as “stacking guide 30b”, and collectively they are referred to as “stacking guides 30b”, this nomenclature is used elsewhere in this description), and stacking guides 35b-1 and 35b-2 (generically, these elongated members are referred to herein as “stacking guide 35b”, and collectively they are referred to as “stacking guides 35b”, this nomenclature is used elsewhere in this description). The support member 50a includes attachment points 70b-1 and 70b-2 (generically, these elongated members are referred to herein as “attachment point 70b”, and collectively they are referred to as “attachment points 70b”, this nomenclature is used elsewhere in this description), and attachment points 75b-1 and 75b-2 (generically, these elongated members are referred to herein as “attachment point 75b”, and collectively they are referred to as “attachment points 75b”, this nomenclature is used elsewhere in this description). The stacking guides 30b and 35b collectively form a base pattern on the support member to mate with the complementary pattern formed but the attachment points 70b and 75b on the bottom of the rigid structure of the support member 50b.
The base pattern formed by the stacking guides 30b and 35b and the complementary pattern formed by the attachment points 70b and 75b are not particularly limited. In the present example, the stacking guides 30b and 35b and the attachment points 70b and 75b are each one of two possible shapes placed in a pattern. In particular, the stacking guides 30b-1 and 35b-2 and the attachment points 70b-2 and 75b-1 may be a substantially similar oval shaped ring. The stacking guides 30b-2 and 35b-1 and the attachment points 70b-1 and 75b-2 may be a substantially similar oval shaped protrusion with dimensions to fit around the attachment points 70b-2 and 75b-1 and the stacking guides 30b-1 and 35b-2, respectively. Accordingly, in the present example shown in
Furthermore, it is to be appreciated that in the present example, the spacing of the stack guides 30b and 35b and the attachment points 70b and 75b are similar in size and symmetrical such that the support member 50b may be stacked in multiple orientations. For example, the support member 50b may be rotated 180° such that the stacking guides 30b-1 and 30b-2 mate with the attachment points 75b-2 and 75b-1, respectively. In addition, the stacking guides 35b-1 and 35b-2 mate with the attachment points 70b-2 and 70b-1, respectively, at the opposite ends of the support members 10b and 50b.
The base pattern and the complementary pattern in the present example may be formed with two basic shapes. Furthermore, it will be appreciated that the attachment points may be used as stacking guides for addition support members and that several support members may be stacked above each other. In particular, stacking guides may be disposed on the top side (not shown) of the support member 50b such that the support member 50b may receive another support member thereon and align the additional support member with both the support member 50b and the support member 10b. In addition, additional attachment points/stacking guides may be disposed on sides of the support member 50b. The additional attachment points/stacking guides may have the same base pattern or complementary pattern such that the support member 50b may be stacked onto of the support member 10b using any of the four sides.

The top surface 31b-1 is not particularly limited and is to generally engage the attachment point 70b-1 of the support member 50b. In the present example, the top surface 31b-1 slopes toward the surface of the elongated member 20b. Accordingly, in this example, the slope may be designed to position the attachment point 70b-1 with gravity. By supporting a substantial amount of weigh on a small area of the top surface 31b-1, the stacking guide 30b-1 may be made from a substantially hard material that is not easily deformed and that the attachment point 70b-1 may slide across the top surface 31b-1 without significantly scratching or damaging the top surface 31b-1.
The pegs 32b-1 are to interact with the elongated member 20b to secure the stacking guide 30b-1 to the elongated member 20b and to prevent lateral movement of the stacking guide 30b-1 when lateral forces are applied, such as if the attachment point 70b-1 is to be dragged across and over the stacking guide 30b-1. The pegs 32b-1 are not particularly limited and may be formed from a molding process to be part of a unitary body. In other examples, the pegs 32b-1 may be attached to the main body of the stacking guide 30b-1. It is to be understood that other substantially oval rings, such as the stacking guide 35b-2 and the attachment points 70b-2 and 75b-1 may have a similar or identical structure to the stacking guide 30b-1.
Referring to
The top surface 31b-2 is not particularly limited and is to generally engage the attachment point 70b-2 of the support member 50b. In the present example, the stacking guide 30b-2 may be formed from similar or identical materials as the stacking guide 30b-1 and thus have similar properties as described above. Accordingly, the stacking guide 30b-2 may be formed from a molding process using a different mold.
It is to be understood that other substantially oval protrusions, such as the stacking guide 35b-1 and the attachment points 70b-1 and 75b-2 may have a similar or identical structure to the stacking guide 30b-2. Furthermore, stacking guides 30b and 35b as well as all attachment points 70b and 75b may be formed using two different molds: one to make oval rings and another to make oval protrusions. Although the present examples illustrate stacking guides 30b each having two pegs 32b, it is to be appreciated that the number of pegs 32b is not limited. In the present example, the two pegs 32b are to secure the stacking guides 30b on the elongated member 20b and restrict rotation on the surface. In other examples, a single peg 32b may be secured to the elongated member 20b with sufficient force to restrict rotation.
Referring to
In the present example, the elongated member 20b includes anchor points onto which the stacking guides 30b may be mounted. The anchor points may be holes to interact with the pegs 32b-1 of the stacking guide 30b-1 and the pegs 32b-1 of the stacking guide 30b-1. The manner by which the pegs 32b-1 and 32b-2 interact with the holes is not limited. For example, the pegs 32b-1 and 32b-2 may be dimensioned to provide a friction fit within the hole such that they may be removeably added to the the elongated element. Accordingly, this may provide for easy replacement or installation if the stacking guides 30b are damaged. In other examples, the pegs 32b-1 and 32b-2 may be welded or soldered within the holes. In further examples, the pegs 32b-1 and 32b-2 may be bucked or riveted to the hole.
Furthermore, it is to be appreciated by a person of skill in the art with the benefit of this description that the stacking guides 30b may be retrofitted or installed on existing support members 10b. In the present example, holes may be drilled into the elongated member 20b to act as anchor points onto which the stacking guides 30b may be mounted. Although this example uses holes as an anchor point, other examples are contemplated. For example, the stacking guides 30b may be installed using adhesives or a magnet such that holes are not used. In such examples, any location on the surface of the elongated member 20b may be used as an anchor point.

In the present example, the stacking guide 30c-1 includes a shaped or curved bottom surface instead of a flat bottom surface. Accordingly, it is to be be appreciated that the stacking guide 30c-1 may be mounted on a rounded elongated member instead of a flat elongated member. For example, the radius of curvature of the stacking guide 30c-1 may be dimensioned to fit a rounded elongated member with a specific radius of curvature. In other examples, the stacking guide 30c-1 may be resiliently deformable such that it may accommodate an elongated member having a radius of curvature within a range. Furthermore, although the stacking guide 30c-1 is shaped to be mounted on a rounded elongated member, it is to be appreciated that the stacking guide 30c-1 may be modified to mount on elongated members having other shapes.
The pegs 32c-1 are to interact with the elongated member 20c to secure the stacking guide 30c-1 to the elongated member 20c and to prevent lateral movement of the stacking guide 30c-1 when lateral forces are applied. The pegs 32c-1 are not particularly limited and may be formed from a molding process to be part of a unitary body. In other examples, the pegs 32c-1 may be attached to the main body of the stacking guide 30c-1. Although the present example shows two pegs 32c-1, other examples may include more pegs 32c-1. Furthermore, some examples may also include a single peg 32c-1 since the curved surface mating with the surface of the rounded elongated member may reduce shifting or rotation of the stacking guide 30c-1 on the surface of the rounded elongated member.

In the present example, the stacking guide 30c-2 includes a curved bottom surface instead of a flat bottom surface. Accordingly, it is to be be appreciated that the stacking guide 30c-2 may be mounted on a rounded elongated member instead of a flat elongated member. For example, the radius of curvature of the stacking guide 30c-2 may be dimensioned to fit a rounded elongated member with a specific radius of curvature. In other examples, the stacking guide 30c-2 may be resiliently deformable such that it may accommodate an elongated member having a radius of curvature within a range. Furthermore, although the stacking guide 30c-2 is shaped to be mounted on a rounded elongated member, it is to be appreciated that the stacking guide 30c-2 may be modified to mount on elongated members having other shapes.
The pegs 32c-2 are to interact with the elongated member 20c to secure the stacking guide 30c-2 to the elongated member 20c and to prevent lateral movement of the stacking guide 30c-2 when lateral forces are applied.

In the present example, the elongated member 20c includes anchor points onto which the stacking guides 30c may be mounted. The anchor points may be holes to interact with the pegs 32c-1 of the stacking guide 30c-1 and the pegs 32c-1 of the stacking guide 30c-1. The manner by which the pegs 32c-1 and 32c-2 interact with the holes is not limited. For example, the pegs 32c-1 and 32c-2 may be dimensioned to provide a friction fit within the hole such that they may be removeably added to the the elongated element. Accordingly, this may provide for easy replacement or installation if the stacking guides 30c-1 and 30c-2 are damaged. In other examples, the pegs 32c-1 and 32c-2 may be welded or soldered within the holes. In further examples, the pegs 32c-1 and 32c-2 may be bucked or riveted to the hole. Furthermore, since the shape of the elongated member 20c, the mating surfaces may provide an additional mechanism to mount the stacking guides 30c-1 and 30c-2. In addition, the elongated member 20c may be shaped to mate with the stacking guides 30c-1 and 30c-2 in a single orientation to hold the stacking guides 30c-1 and 30c-2 at a specific location. For example, if the elongated member 20c had an oval cross section instead of a circular cross section, the stacking guides 30c-1 and 30c-2 may be dimensioned to fit at the top of the elongated member 20c.
Furthermore, it is to be appreciated by a person of skill in the art with the benefit of this description that the stacking guides 30c-1 and 30c-2 may be retrofitted or installed on existing support members 10c. In the present example, holes may be drilled into the elongated member 20c to act as anchor points.
It should be recognized that features and aspects of the various examples provided above may be combined into further examples that also fall within the scope of the present disclosure.
