Definitions
- the present invention relates generally to tools and accessories.
- the present invention relates to a tool holder for portable power tools.
- Tools are widely used in construction, maintenance, industrial facilities, and emergency situations. Some tasks require work be completed at elevated heights and are extremely time- and space-sensitive. For safety reasons, tools may be secured to relatively stationary objects such as people or structures such as buildings, vehicles, and equipment such as ladders or aerial buckets and the like. Previous methods for securing tools include holding tools in a receptacle or placing them on the floor of an aerial bucket while not in use. Previous methods can be improved by providing an apparatus to provide convenient access to the tool while preserving premium space for other critical functions.
- the chain saw holder includes a clamp for clamping to a fixed support, an extension member extending away from the clamp to a handle bar attachment, a mouth on the handle bar attachment for receiving the handle bar and releasably gripping the handle bar.
- the attachment is adapted to provide for pivotal movement of the mouth about an axis generally perpendicular to the extension member so that the gripped portion of the handle bar is received by the mouth and is gripped in any orientation aligned with, oblique to, or perpendicular to the extension member.
- the chain saw holder is capable of holding and supporting the saw regardless of the orientation of the fixed support.
- the chain saw holder includes a cutter bar retaining portion for frictionally engaging the chain saw cutter bar and a handle retaining portion for selectively receiving and capturing the chain saw elongate front handle. It also has a stop member selectively movable along an elongate arm for selective placement over the U-shaped section which is able to capture the chain saw handle.
- the tool holder for an aerial bucket lift includes a backboard with left, right, front, and back sides.
- a left side member and a right side member are attached to the left and right sides, respectively, of the backboard.
- a scabbard portion is attached to the front side of the backboard; it forms a pocket with the backboard.
- a left hook and a right hook extend from the left side member and right side member, respectively, which are configured to couple to a bucket of an aerial bucket lift.
- Holders can be used to store and/or carry a variety of tools. Different types of holders hold and support different types of tools and are often molded to the type of tool they are intended to store and/or carry. For example, a holder may store and/or carry a hammer, chainsaw, personal breathing apparatus, or firearm. Each of these holders may be molded into a different shape to better fit the particular tool it holds. A tool holder is often attached to a relatively stationary object such as a vehicle, an aerial apparatus, a building, or a person.
- aerial apparatuses Real estate on and within aerial apparatuses is at a premium, but the proper tools are still necessary to complete tasks.
- Some holders may be attached to aerial apparatuses such as aerial bucket trucks, fire truck ladder buckets and the like or to ladders having reinforcing structures. Attaching a holder to an aerial apparatus allows a user to secure a tool to the aerial apparatus to maximize space while still providing access to necessary tools. In firefighting situations, such available space may be critical when the aerial apparatus is used for saving a person from a burning building.
- Previous methods can be improved upon by further providing a chainsaw holder affixable to an aerial apparatus.
- the present invention achieves these and other objectives by providing a chainsaw holder to secure a chainsaw to an aerial apparatus.
- the chainsaw holder has unitary holder body.
- the unitary holder body has an inside body surface, an outside body surface, a holder body width, a holder body length that is greater than the holder body width, a top hook portion having a top hook portion opening oriented parallel to the inside surface, a cutter bar retaining portion having a proximal retaining portion end and a distal retaining portion end, the cutter bar retaining portion connected on the proximal retaining portion end to the top hook portion, and a guard portion connected to and extending from a distal retaining portion end where the cutter bar retaining portion forms a bump out that extends away from the top hook portion opening and relative to the top hook portion and the guard portion.

Abstract
Description
- The present invention relates generally to tools and accessories.
- Particularly, the present invention relates to a tool holder for portable power tools.
- Tools are widely used in construction, maintenance, industrial facilities, and emergency situations. Some tasks require work be completed at elevated heights and are extremely time- and space-sensitive. For safety reasons, tools may be secured to relatively stationary objects such as people or structures such as buildings, vehicles, and equipment such as ladders or aerial buckets and the like. Previous methods for securing tools include holding tools in a receptacle or placing them on the floor of an aerial bucket while not in use. Previous methods can be improved by providing an apparatus to provide convenient access to the tool while preserving premium space for other critical functions.
- One approach of securing tools is disclosed in U.S. Pat. No. 4,657,234 to Stout for a chain saw holder. The chain saw holder includes a clamp for clamping to a fixed support, an extension member extending away from the clamp to a handle bar attachment, a mouth on the handle bar attachment for receiving the handle bar and releasably gripping the handle bar. The attachment is adapted to provide for pivotal movement of the mouth about an axis generally perpendicular to the extension member so that the gripped portion of the handle bar is received by the mouth and is gripped in any orientation aligned with, oblique to, or perpendicular to the extension member. The chain saw holder is capable of holding and supporting the saw regardless of the orientation of the fixed support.
- Another approach of securing tools is disclosed in U.S. Pat. No. 6,648,152 B2 to Bermes for a chain saw holder. The chain saw holder includes a cutter bar retaining portion for frictionally engaging the chain saw cutter bar and a handle retaining portion for selectively receiving and capturing the chain saw elongate front handle. It also has a stop member selectively movable along an elongate arm for selective placement over the U-shaped section which is able to capture the chain saw handle.
- Another approach of securing tools is disclosed in U.S. Published Application No. 2014/0151420 A1 to Reeves for a tool holder for an aerial bucket lift. The tool holder for an aerial bucket lift includes a backboard with left, right, front, and back sides. A left side member and a right side member are attached to the left and right sides, respectively, of the backboard. A scabbard portion is attached to the front side of the backboard; it forms a pocket with the backboard. A left hook and a right hook extend from the left side member and right side member, respectively, which are configured to couple to a bucket of an aerial bucket lift.
- Holders can be used to store and/or carry a variety of tools. Different types of holders hold and support different types of tools and are often molded to the type of tool they are intended to store and/or carry. For example, a holder may store and/or carry a hammer, chainsaw, personal breathing apparatus, or firearm. Each of these holders may be molded into a different shape to better fit the particular tool it holds. A tool holder is often attached to a relatively stationary object such as a vehicle, an aerial apparatus, a building, or a person.
- Real estate on and within aerial apparatuses is at a premium, but the proper tools are still necessary to complete tasks. Some holders may be attached to aerial apparatuses such as aerial bucket trucks, fire truck ladder buckets and the like or to ladders having reinforcing structures. Attaching a holder to an aerial apparatus allows a user to secure a tool to the aerial apparatus to maximize space while still providing access to necessary tools. In firefighting situations, such available space may be critical when the aerial apparatus is used for saving a person from a burning building.
- Previous methods can be improved upon by further providing a chainsaw holder affixable to an aerial apparatus.
- It is an object of the present invention to provide a chainsaw holder.
- It is another object of the present invention to provide a mechanism for securing a chainsaw while occupying a minimal amount of space.
- It is still another object of the invention to provide a space efficient mechanism for attaching a chainsaw to an aerial apparatus. The present invention achieves these and other objectives by providing a chainsaw holder to secure a chainsaw to an aerial apparatus. In one embodiment of the present invention, the chainsaw holder has unitary holder body. The unitary holder body has an inside body surface, an outside body surface, a holder body width, a holder body length that is greater than the holder body width, a top hook portion having a top hook portion opening oriented parallel to the inside surface, a cutter bar retaining portion having a proximal retaining portion end and a distal retaining portion end, the cutter bar retaining portion connected on the proximal retaining portion end to the top hook portion, and a guard portion connected to and extending from a distal retaining portion end where the cutter bar retaining portion forms a bump out that extends away from the top hook portion opening and relative to the top hook portion and the guard portion. The cutter bar retaining portion has an entry portion with a second slot extending completely through the entry portion and an exit portion with a first slot extending completely through the exit portion where the second slot and the first slot are aligned to thereby allow a distal end of a cutter bar of a chainsaw to extend through the second slot and the first slot with the second slot being adjacent a proximal end of the cutter bar of the chainsaw.
- In another embodiment, the top hook portion has a first segment, a second segment extending perpendicularly from the first segment, and a third segment extending perpendicularly from the second segment and parallel to and facing the first segment wherein the third segment extends to and is connected to the proximal retaining portion end of the cutter bar retaining portion and wherein the first segment, the second segment and a portion of the third segment form a U-shaped cross-section portion.
- In further embodiment, the U-shaped cross-section portion is transverse to the holder body length.
- In another embodiment, the U-shaped cross-section portion is approximately perpendicular to the holder body length.

- In another embodiment, the entry portion meets the exit portion at an approximate right angle.
- In another embodiment, the top hook portion is adapted to attach to a relatively stationary object.
- In still another embodiment, the relatively stationary object is one of an aerial bucket lift, an aerial fire bucket or a ladder apparatus.
- In one embodiment of the present invention, the entry portion aperture is a slot having a length that is 1.1 to 1.7 the width of a chainsaw cutter bar and a width that is in a range of 1.1 to 1.3 times a thickness of the chainsaw cutter bar.
- In another embodiment, the exit portion aperture is a slot having a width larger than the width of the entry portion aperture.
- In another embodiment, the exit portion aperture is a slot having a length that is 1.1 to 1.7 the width of a chainsaw cutter bar and a width that is in a range of 2.0 to 4.4 times a thickness of the chainsaw cutter bar.
- In another embodiment, a ratio of the holder body length to the holder body width is in a range of 2.0 to 3.8.
- In one embodiment of the present invention, the entry portion and the exit portion together have a lineal distance of approximately 6 inches.
- In another embodiment of the present invention, the chainsaw holder has an integral holder body. The integral holder body includes an inside body surface, an outside body surface, a holder body width, a holder body length that is greater than the holder body width, a top hook portion having a top hook portion opening oriented parallel to the inside surface, a cutter bar retaining portion having a proximal retaining portion end and a distal retaining portion end, and a guard portion connected to and extending from the top hook portion as a continuous sheet. The cutter bar retaining portion is a separate component that is fixedly attached to the guard portion forming a bump out that extends away from the top hook portion opening and relative to the top hook portion and the guard portion. The cutter bar retaining portion has an entry portion with a second slot extending completely through the entry portion and an exit portion with a first slot extending completely through the exit portion where the second slot and the first slot are aligned to thereby allow a distal end of a cutter bar of a chainsaw to extend through the second slot and the first slot with the second slot being adjacent a proximal end of the cutter bar of the chainsaw.
- In another embodiment, a method of making a chainsaw holder is disclosed. In this embodiment, a single sheet of bendable yet rigid or semi-rigid material is used.

FIG. 10 , another embodiment of the present invention is illustrated. This embodiment is tailored to engage with an aerial fire apparatus. Specifically, this embodiment engages with an aerial fire ladder. The same components in both embodiments have the same reference numbers. - Like the first embodiment,
chainsaw holder 200 has atop hook portion 210 with a top hook portion opening 210 a, a cutterbar retaining portion 115, and aguard portion 140. Cutterbar retaining portion 115 has a proximal retainingportion end 122 and a distal retainingportion end 132. Between proximal retainingportion end 122 and distal retainingportion end 132 is anentry portion 120 and anexit portion 130.Entry portion 120 is connected to exitportion 130.Entry portion 120 andexit portion 130 are between thetop hook portion 210 and theguard portion 140, forming an angled connecting bridge between thetop hook portion 210 and theguard portion 140.Exit portion 130 includesfirst slot 134. -
FIG. 11 is a rear perspective view of thechainsaw holder 200.Entry portion 120 has asecond slot 124 disposed in and extending completely through theentry portion 120.Entry portion 120 connectsthird segment 116 to exitportion 130. Similarly,exit portion 130 connectsentry portion 120 toguard portion 140. As seen in theFIGS. 1 and 2 ,cutter bar portion 115 forms a bump out away from top hook portion opening 210 a relative totop hook portion 210 andguard portion 140. The major difference betweenchainsaw holder 200 andchainsaw holder 100 is the angle oftop hook portion 210 relative to the holder body length HBL. Instead of being substantially perpendicular to holder body length HBL,top hook portion 210 is transversely angled relative to holder body length HBL. The angle is typically formed to be substantially similar to an angle of a bracing portion of a fire ladder so that when a chainsaw is being held bychainsaw holder 200, the chainsaw cutter bar is in a vertical oriented position as opposed to being in a horizontal oriented position. The typical angle is a 45° angle. -

FIG. 18 illustrates another embodiment of the present invention showing achainsaw holder 300 having anintegral holder body 107. The difference between this embodiment and the first disclosed embodiment inFIG. 1 is that the cutterbar retaining portion 115′ is a separate component that is fixedly attached to theholder body 107 by attachment mechanisms such as, for example, welding, adhesives, ultrasonic bonding, etc., all as is well known in the art. Further,holder body 107 hasthird segment 116 oftop hook portion 210 directly connected to guardportion 140 as a continuous sheet with cutterbar retaining portion 115′ fixedly attached tooutside surface 105 a ofholder body 107. - One method of making the present invention is disclosed using a single sheet of bendable yet rigid or semi-rigid material. The method includes obtaining the sheet of material for forming a unitary holder body having two sides and a first end and a second end. A first slot is formed through the unitary holder body where the first slot has a length between the at least two sides. The slot is located a predefined distance from the first end of the unitary holder body. A second slot is formed through the unitary holder body where the second slot has a length between the at least two sides. The second slot is located parallel to the first slot and having a width that is narrower than a width of the first slot and where the first slot is between the second slot and the first end of the unitary holder body. A first bend in created in the unitary holder body at approximately a 45° angle a predefined distance from the first end of the unitary holder body where the first bend is adjacent to the first slot. A second bend is created in the unitary holder body at approximately a 90° angle a predefined distance from the first bend. The second bend is formed in an opposite direction from the first bend, the second bend being at a predefined distance that is at approximately midway between the first slot and the second slot where a sheet portion between the first bend and the second bend forms the exit portion. A third bend is created in the unitary holder body at approximately a 45° angle a predefined distance from the second bend, the third bend being in an opposite direction from the second bend. The third bend is located at a predefined distance that positions the second slot approximately midway between the second bend and the third bend where a portion of the unitary holder body between the second bend and the third bend forms the entry portion. The top hook portion is formed at the second end of the unitary holder body having one of a first orientation or a second orientation.
- When selecting the first orientation for the chainsaw holder, the unitary holder body is cut perpendicularly to the holder body width at a predefined distance from the third bend, the predefined distance being sufficient to form the top hook portion at the second end. A fourth bend is created in the unitary holder body at approximately a 90° angle a predefined distance from the third bend, the fourth bend being in an opposite direction from the third bend, and a fifth bend in the unitary holder body is created at approximately a 90° angle a predefined distance from the fourth bend, the fifth bend being formed in the same direction as the fourth bend where the fourth bend and the fifth bend form a U-shaped cross-section.
- When selecting the second orientation for the chainsaw holder, the unitary holder body is cut at an angle that is transverse to holder body width forming the second end into an angled end of the unitary holder body that is opposite the first end. A fourth bend is created that is parallel to the angled end of the unitary holder body. The fourth bend is formed at approximately a 90° angle a predefined distance from the angled end, the fourth bend being in an opposite direction from the third bend. A fifth bend is created in the unitary body at approximately a 90° angle a predefined distance between the angled end and the fourth bend and parallel to the angled end. The fifth bend is formed in the same direction as the fourth bend, the fourth bend and the fifth bend forming a U-shaped cross-section.
