Problem Identification:
There are many challenges that go into something as simple as sitting down, particularly with regards to
seating. In the case of seating for sportsman’s chairs, the challenges arise immensely. Not only does a
chair have to be capable of supporting its user during normal activities, but also during high activity and
mechanical stress events such as fishing and other sporting events. A Sportsman’s chair also has to deal
with terrains that are not ideal on many occasions, such as from banks, boats, and at sporting events,
where substandard ground conditions can hamper a chairs ability to perform. Furthermore, because of
these various locations of use, it is necessary for a sportsman’s chair to be collapsible for carrying and
storage. While many designs for this brand of chair exist, there is no one single solution to meeting the
challenges. This project seeks to provide yet another solution to the following set of challenges:
1. To create a design for a sportsman’s chair that can be used for fishing, camping, at sporting
events, and for other purposes.
2. To create a design that is collapsible for ease in carrying and storage.
Design Analysis
The primary success or failure of a chair is highly dependent on its level of comfort. Although a
sportsman’s chair is designed to be in rugged environments, users do not want a rugged feeling chair to
match. Because of the harshness of the conditions that the design would be exposed to, it is necessary
to seal the sensitive components of the chair within a protective shell to prevent against corrosion and
interference due to external materials. The primary area where this is important is the rotational unit of
the chair. Because of this, this design calls for an interlocking cub that the inner shaft sits within in order
to prevent damage to the internal components. These shaft cups hold the critical folding part of the
design, enabling the upper and lower segments to come together to be folded into a transportable
option. These cups attach to the support ring on either side, which the fabrics of the seat connect to.
This allows for a lightweight seating material, a layer of strong, waterproof fabric, to be utilized for the
design. In order to further increase the strength of the chair material, U-bolts are placed through the
support structure to connect to the fabric. This both increases the strength of the fabric through
additional connection points, and also helps to prevent slipping of the fabric over the chairs support
structure. The U-bolts are shortened, and their ends are capped to prevent dangerous sharp edges and
burrs. The chairs lower body structure then connects to several rotation points, which connect to the
legs of the chair. These legs are designed to be moveable from a upright standing position to a
collapsed position through the use of the inner pin design. This allows the user to pull on the leg’s foot
to free the leg and rotate it into its stored position, where it is kept in place through elastic straps. The
individual foot-pad designs allow for mass manufacture of the sub-assembly, having to stock less repair
parts, and also giving greater flexibility for the chair to handle rough terrain.
The Upper segment of the chair contains a similar attachment structure as the lower segment
for the fabric, allowing high strength at this point. The upper segment also contains the arms of the
chair, which are connected through a friction mounted box plate and rotate around a central gear to
produce a smooth travel for the arms movement.
All materials, with the exception of some fasteners and the arms themselves, are constructed
out of lightweight Aluminum Alloy. This allows for weigh savings over a conventional metal, while still
retaining significant strength in the system. Further details on the design parts can be found below in
the Parts Analysis table.
