Abstract
A device for installing a tire chain is a one-piece, rugged tool made of 3/8"(1.0 cm) or 1/2" (1.3 cm) steel stock. The tool has a total length of approximately 1 foot (30 cm). At a first end, the tool has an arcuate shape that terminates in an open channel, which channel functions to grab a chain hook and to lever the hook into engagement with a chain link. The second end of the tool is L-shaped and terminates in an elliptical-shaped member dimensioned to fit a conventional cam-loc tightening device.
Description
TIRE CHAIN TOOL
BACKGROUND OF THE INVENTION
1. FIELD OF THE INVENTION
The present invention generally relates to hand tools. More specifically, the present invention is drawn to a tool adapted to assist in mounting chains on automotive vehicle tires, especially truck tires.
BACKGROUND OF THE INVENTION
1. FIELD OF THE INVENTION
The present invention generally relates to hand tools. More specifically, the present invention is drawn to a tool adapted to assist in mounting chains on automotive vehicle tires, especially truck tires.
2. DESCRIPTION OF THE RELATED ART
Installing chains on truck tires to enhance traction on snow and ice can be a tedious and frustrating procedure. It is important that the chain fits tightly on the tire to prevent the chain from loosely slapping the road surface and truck body thereby causing wear to the chain and damage to the truck.
Many devices have been advanced for simplifying the arduous task of mounting tire chains. For example, U.S. Patent numbered 1,372,195 (Rounds) shows a device for securing a chain to a tire.
The device functions as only a temporary securing means and must be removed before the chain can be correctly secured.
U.S. Patent numbered 1,483,686 (Searfoss) is drawn to a lever hook for connecting the ends of tire chains. The device is adapted to remain on the chains as a connector.
U.S. Patents numbered 3,408,884 (Musgrove), 4,411,176 (Mason) and 5,079,976 (Priest) disclose tools for installing chains on dual-wheeled vehicles. The tools require that the vehicle be moved forwardly for the chains to be properly mounted.
U.S. Patent numbered 3,896,687 (Cloud) shows a magnetic tire chain installation device. The instant device also requires that the vehicle be moved to properly mount the chains.
U.S. Patents numbered 3,680,834 (Holloway) and 4,042,210 (Feldmann) are drawn to tools having "working"
configurations at both ends thereof. Neither patentee contemplates utilizing the tool to assist in the installation of tire chains.
U.S. Patent numbered 1,437,158 (Snodgrass) is drawn to a tool similar to Applicants' invention. However, the Snodgrass tool utilizes a cup designed to engage a chain hook. Also note that the configuration of Applicants' invention is different from that of the Patentee.
Japanese Patent numbered 10119525 A (Nakao) shows a tool having a cam lock opener at its end. Nakao does not contemplate providing a complete tool as disclosed by Applicants.
None of the above invention and patents, taken either single or in combination, is seen to discloses a rugged, one-piece tool for assisting tire chain installation as will be subsequently described and claimed in the instant invention.
DISCLOSURE OF THE INVENTION
This disclosure is directed to a tire chain tool.
The tire chain tool includes an elongate tubular body member having a proximate end and a distal end. An arcuate portion defines the proximate end of the tubular body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The tire chain device is a one-piece, rugged tool made of 3/8" (1.0 cm) or 1/2" (1.3 cm) steel stock. In its preferred embodiment, the tool has a total length of approximately 1 foot (30 cm), but can be made longer or shorter dependent on a prospective user's preference.
At a first end, the tool is provided with an open channel, which open channel is capable of efficiently grabbing any conventional quick chain hooks and levering the hook into engagement with a chain link. The second end of the tool terminates in an elliptical configuration that is dimensioned to fit a conventional cam-loc structure, which cam-loc structure is common to most truck tire chains. The second end can thereby be utilized to tighten the cam-loc. The tool can be utilized to aid in the mounting of chains on automotive vehicle tires. The tool is of one-piece fabrication and has no moving parts. Easy to use, the tool is fabricated from rugged material and will withstand wear and tear.
Attention is first directed to Fig. 1 wherein the tool comprises an elongate tubular body 10 fabricated from a rugged material such as steel stock. The proximate end of body 10 is defined by an arcuate portion 14. Portion 14 has an inside surface 14a, which inside surface is beveled in order to reduce the surface area in contact with the chain link. This design decreases the amount of force required to lever the link to engage the hook. Portion 14 terminates in a member 12, which member 12 is configured as an open-end channel. Portion 14 is positioned immediately adjacent portion 12. A triangular-shaped protuberance or nock 30 is positioned at the junction of body 10 and portion 14. Nock 30 prevents the chain link from sliding up the body 10 during the leveraging process and also provides a leveraging point. The distal end of body 10 terminates in an L-shape, from which extends an extruded elliptical member 16. Member 16 is approximately one inch (2.5 cm) long and is sized to be received in the opening of a conventional chain cam-loc device as will be explained below. Member 16 is positioned in the same vertical plane as portion 14.
Attention is now directed to Figs. 2-5 wherein the device is illustrated in use. In Fig. 2 the device is shown in the initial position wherein channel portion 12 is manipulated, by a user 4, to grasp the end of a chain hook 20. Note that beveled surface 14a is disposed within chain link 22. Fig. 3 shows an intermediate position wherein hook 20 is maneuvered in a position to engage link 22. In a final position (Fig. 4), hook 20 is levered into engagement with link 22. Fig. 5 shows an initial position wherein the channel engages the body of a chain link.
Fig. 6 illustrates a scenario where member 16 is inserted in a cam-loc device 24 to tighten the chain.
It is to be understood that the present invention is not limited to the embodiment described above, but encompasses any and all embodiments within the scope of the following claims.
