Many attempts have been made to create an accurate bolt rifle action bedding method that consistently provides a solid base to mount an action to a chassis or stock. There are a multitude of different types of bedding methods from basically screwing to wood or composite type stocks which tend to be the least accurate to screwing to solid milled stocks formed from a single metal blank, which may be more accurate. Accuracy seems to increase when the action is bedded in a non-movable bedding configuration. Even the slightest movement of the action in the stock will reduce accuracy significantly. Due to the many companies and gunsmiths that manufacture bolt action rifles; and the multitude of action size variations, every rifle comes with its own unique stock. If a bolt action rifle owner wanted a new stock, they would self-manufacture or purchase a stock that fit their specific action.

Although bedding of an action is of prime importance to accuracy, of equal importance is the ability of the shooter to have a consistent length of pull, cheek height, sight plane, rifle balance and weight to name a few. This is hard to achieve based on the variance of stock/action combinations and the caliber length. When rifles between different manufactures are shot by the same shooter, accuracy is generally reduced because of the inability of the shooter to maintain that consistent feel and placement of the stock/action between different action combinations. The multitude of manufactures and their unique designs and dimensions have required individual and costly chassis and stocks due to these dimensional variations maintain that consistent feel and placement of the stock/action between different action combinations.

Several types of modular stocks or chassis have been proposed or described—for example U.S. Pat. No. 8,079,169 to Gregg (2011), U.S. Pat. No. 7,841,119B1 to Boyd (2010) and U.S. Pat. No. 6,293,040 (2001) to Luth. Additionally, U.S. patent applicant Eberle described with 20040211104 (2003) a modular stock system. Although similar in modularity, and in some application, usable with more than one bolt action style, in some applications the stock and chassis are fragmented and reduce strength, thereby reducing accuracy. Also, some applications use a specific unique manufacturing design that preclude the use of other manufactures bolt action receivers, including single application triggering systems. Other types of modular chassis and stocks require the use of components other than the action to be transferred from the original stock or chassis to the described design, such as trigger guards or floor plates, creating more, not less exclusivity of receivers. My own application uses a chassis or stock shaped from a single piece of material, not fragments that reduce the strength of the stock or chassis. My design of the Versa-Fit Modular Bedding block uses only the existing receiver with no additions or removals of significant or insignificant parts of the existing chassis or stock, creating more, not less modularity and acceptance of a myriad of bolt action receivers. Nevertheless, all modular and non-modular stocks and chassis heretofore known suffer from a number of disadvantages:

• • (a) Limited number of production bolt action receiver applications due to an additional existing parts use requirements requiring multiple chassis designs.
  • (b) A loss of chassis strength due to a fragmentation of the longitudinal configuration of the chassis.
  • (c) Additional cost of single application stocks and chassis due to specific bolt action receiver design.
  • (d) Site in requirements after each bolt action receiver change due to movement of action in bedding area.

SUMMARY

In accordance with one embodiment an integrated chassis and stock system with versa-fit modular bedding block consists of a chassis or stock with a recess that accepts a unique modular bedding block with its attached bolt action and is held in place with a securing wedge or screw.

Advantages

The Chassis and Stock Integration System accepts the Versa-Fit Modular Bedding Block and allows for multiple (virtually unlimited) bolt action designs to be used in a single chassis system. There is no change in the fit of the rifle and the shooters individual preference remain consistent based on the length of pull, cheek height, sight plane, rifle balance and weight, regardless of the variations of the action dimensions and attachment design. A single shooter implementing the multiple modular bedding blocks can remove and replace the individual action designs into a single chassis with no fit deviations, feel, or balance issues. This method increases accuracy because of the secure bedding of the action into its modular bedding block while simultaneously reducing cost, storage, and weight because one chassis fits all bolt actions designs.

DETAILED DESCRIPTION

FIGS. 1; 2; 4C and 6—First Embodiment

The (FIG. 1) Modular Integrated Chassis System is constructed of three individual components, the (FIG. 3) Chassis, the 14 Versa-Fit Modular Bedding Block, and the 16 Wedge Locking Block. In the first embodiment of the Chassis and or Stock the material is 7075 T6 aluminum. In other embodiments, the chassis and or stock could be hardwood, composite of unlimited plastics and/or wood, or other types of metals, with rigidity and weight being the limiting factors. Versa-Fit Modular Bedding Block, in one embodiment, the material of construction is metal, 7075 T6 aluminum. Materials for other embodiments are only limited by the strength and rigidity of the material. The 16 Wedge Locking Block in one embodiment, is constructed of Stainless Steel. The strength and corrosion resistance of Stainless Steel is preferred as the 16 Wedge Locking Block is the primary securing component of the Versa-Fit Modular Bedding Block to the 12 Chassis or Stock. Other embodiments could be high strength composites of various other metals with the ability to be threaded and thread life the limiting factor. The 12 Modular Integrated Chassis is the component that securely holds the individual unique Versa-Fit Modular Bedding Block tightly in, on, or around the 12 (FIG. 3); (FIG. 3C) Chassis or stock receiving location of the rifle chassis or stock. The 14 Versa-Fit Modular Mounting Block holds the bolt action in the 12 Modular Integrated Chassis System, regardless of the 10 (FIG. 1) bolt action dimensions on the interior of the 14 Versa-Fit Modular Bedding Block. The exterior dimensions of the 14 Versa-Fit Modular Bedding Block never change and fits into, over or around the 14 Versa-Fit Modular Bedding Block receiving section of the (FIG. 1) Chassis Integration System. The 14 Versa-Fit Modular Bedding Block is held in place in the 12 (FIG. 6) Modular Integrated Chassis System by multiple means that securely holds the 14 Versa-Fit Modular Bedding Block in the front and rear of the 20 Chassis Receiving section where it is aligned consistently and repeatedly with multiple alignment methods.

Operation FIGS. 1; 6 & 6.A

The 14 Versa-Fit Modular Bolt Action Bedding Block and 2 The Modular Integrated Chassis System is designed for 10 bolt style actions. The Modular Integrated Chassis System is designed to be used in conjunction with the 14 Versa-Fit Modular Bedding Block and 16 Integral Wedge Locking Block. The (FIG. 6A) Chassis Integration System accepts the 14 Versa-Fit Modular Bedding Block and allows for multiple (virtually unlimited) 10 bolt action designs to be used in a single chassis system. The 16 Wedge Locking Block secures and locks the 14 Versa-Fit Modular Bedding Block in place. The 16 (FIG. 6) Wedge Locking Block, using the 36 Wedge Locking Block Fasteners, is pulled vertically between the angular face of the 16 Wedge Locking Block and the 18 (FIG. 3A)

(FIG. 3D) Chassis Stop Block. The corresponding 34 (FIG. 6A) Wedge Locking Block Slide Face pushes the 14 Versa-Fit Modular Bedding Block rearward and with the 22 (FIG. 3C); (FIG. 4A) Steel Alignment Pin and 24 Collar hold the 14 Versa-Fit Modular Bedding Block securely in place in, on, or around the 20 (FIG. 3) Receiving Section of the 12 Chassis. The 32 (FIG. 4); (FIG. 4A); (FIG. 4B); (FIG. 4C) Lateral Movement Locking Slot in conjunction with the 38 (FIG. 5); (FIG. 5A) Lateral Movement Wedge Lock control lateral movement of the Versa-Fit Modular Bedding Block within the 20 Receiving Section of Chassis. (FIG. 1) The Modular Integrated Chassis and Stock System holds the 14 Versa-Fit Modular Bedding Block securely in place and has the (FIG. 2) external dimensions that match the external dimensions of the 12 Modular Bedding Block so that fit and finish of the two joined parts solidly mate for repeatable remove and replacement activities that are repeatable.

FIGS. 1; 3A-3B Alternative Embodiments

There are various possibilities with regard to the attachment of the Versa-Fit Modular Bedding Block. FIGS. 3A and 3B show that the 14 Versa-Fit Modular Bedding Block can be attached with a single fastener as shown as a screw access hole 7. This embodiment will remove the need for the 16 Wedge Locking Block by using a screw fastener attachment of the 14 Versa-Fit Modular Bedding Block through the 7 Screw Access Hole in the base of the Chassis or Stock. This method may be the preferred attachment in a situation where a heavy recoiling cartridge is used in the (FIG. 1) The Modular Integrated Chassis and Stock System could cause additional flexing of the actual 12 Chassis and reduce accuracy. Additional embodiments occur with the attachment of the 14 Versa-Fit Modular Bedding Block in various methods on or around a Chassis or Stock with various means using threaded fasteners in the rear, top or bottom of a Chassis or Stock.

Advantages

From the descriptions above some embodiments of my Integrated Chassis and Stock System with Versa-Fit Modular Bedding Block become evident.

(a) The Modular Integrated Chassis System maintains the individual shooters preset fit and feel regardless of specific Modular Bedding Block inserted with its corresponding action.

(b) The Modular Integrated Chassis System contains the wedge stop block that is used exclusively to provide solid mounting while directing linear force through the Modular Bedding Block, by accepting the Wedge Locking Block as it is inserted into and properly torqued between the wedge stop block and the Modular Bedding Block

(c) The Modular Bedding Block is held in place in, on, or around the chassis or stock by multiple means that securely holds the Modular Bedding Block in the front and rear of the Chassis Integration System section where it is aligned consistently and repeatedly with multiple alignment methods.

(d) The Chassis or Stock Integration System accepts the Modular Bedding Block and allows for bolt action designs to be used in a single chassis system.

(e) There is no change in the fit of the rifle or the shooters individual preference remain consistent based on the length of pull, cheek height, sight plane, rifle balance and weight, regardless of the variations of the action dimensions and attachment design.

(f) This invention increases accuracy because of the Wedge Locking Block System, while simultaneously reducing cost, storage, and weight because one chassis fits all bolt actions designs.

CONCLUSIONS, RAMIFICATIONS, AND SCOPE

Accordingly, the reader will see that the Modular Integrated Chassis and Stock System holds the Versa-Fit Modular Bedding Block securely in place and has the external dimensions that match the external dimensions of the chassis and stock so that fit and finish of the two joined parts solidly mate for removal and replacement activities that are repeatable. The Modular Integrated Chassis System also maintains the individual shooters preset fit and feel regardless of specific Modular Bedding Block inserted with its corresponding action. Additionally, the versatility and cost reduction of one chassis system that accepts multiple styles of bolt action designs is both heretofore unachieved for the common and un-common production bolt action receivers, as well as any number of custom embodiments.

Furthermore, this Modular Integrated Chassis and Stock System with Versa-Fit Modular Bedding Block has additional advantages in that:

• • each unique bolt action design will have its own properly internally dimensioned Modular Bedding Block for accuracy and flexibility.
  • bolt actions from same manufacturer and of same model can be used interchangeably with a single Modular Bedding Block.
  • bolt actions from the same manufacturer but of different models will have their own unique Modular Bedding Block for internal dimensions.
  • the exterior of the Modular Bedding Block is dimensionally consistent regardless of bolt action style, size, and manufacturer.
  • is designed to securely hold the Modular Bedding Block in the Modular Bolt Action Bedding Block and Chassis or Stock in a constant linear stress free position.
  • There is no change in the fit of the rifle or the shooters individual preference remain consistent based on the length of pull, cheek height, sight plane, rifle balance and weight, regardless of the variations of the action dimensions and attachment design. A single shooter implementing the multiple modular bedding blocks can remove and replace the individual action designs into a single chassis with no fit deviations, feel, or balance issues.
  • This method increases accuracy because of the Wedge Locking Block System, while simultaneously reducing cost because one chassis fits all bolt actions designs.
