Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a magazine device for a fastener driving tool, and more particularly, a magazine is removable from the fastener driving tool, and the magazine accommodates different types of fasteners, each of which has a different type of fastener. The present invention relates to a magazine apparatus for a fastener driving tool, wherein the magazine is replaceable with respect to the fastener driving tool, and the magazine is either a single use disposable magazine or a multiple use refillable magazine.

BACKGROUND OF THE INVENTION Many types of fastener drive tools have been proposed. As used herein, the term fastener is used in its broadest sense and includes almost any fastener that can be driven into a workpiece. Examples of such fasteners include headed nails, headless nails, staples, and clamping nails such as those described in U.S. Pat. No. 4,058,047.

The most common form of fastener drive tool is empty F1-
Driving j type down! may be mentioned. Prior art thinkers have developed many types of pneumatically driven ≧111 fast snow-driven T-shells to a very safe level and sophisticated devices, one type of which is covered by U.S. Pat. No. 3.961. No. 659.

More recently, electro-mechanical fastener drive tools that utilize solenoid or flywheel mechanisms to drive (drive) fasteners have gained attention. Electro-mechanical fastener drive tools are of particular value for home use and for industrial use where sources of compressed air pressure are not readily available. ■ Like this
A shellfish example is shown in US Pat. No. 4,298,072.

The fastener driving tool which stated the above is a single-stroke type in which the fastener is driven by a single use of the driver.1 Prior art has further described a multiple-impact type in which the fastener is driven by multiple impact forces applied by the driver. A type (repeated type) fastener drive tool is used -11=. An example of a multi-impact fastener drive tool is disclosed in the application entitled Multi-impact Fastener Drive Tool, commonly assigned to the present invention. The present invention is applicable to any type of fastener drive tool, and the nature of the fastener drive tool of the present invention is not intended to limit the invention to a capillary, except as limited by the claims.

Replaceable magazines for fastener drive tools are not new per se. Many conventional fastener drive tools can be equipped with different magazines depending on the size of the fastener. However, in order to change a magazine from one magazine to another, it required more tools and more parts and assemblies had to be replaced. The magazines of most fastener-driving tools are not easily interchangeable. One of the primary objectives of the present invention is to replace different magazines containing different types of fasteners without the need for frequent use or mechanical proficiency. To provide a magazine storage that can be attached to a fastener driving tool without having to use a fastener drive tool.

The magazine device of the present invention has many advantages. As pointed out above, the magazine device of the present invention has many advantages.
I-shot type fastener drive - shell tool One impact two fastener drive - Can also be used for shells. Many different types of fasteners can be attached to one fastener by simply manually removing a magazine containing one type of fastener from the tool and installing a magazine containing another type of fastener in its place. It can be driven in with a drive tool.

Each magazine has a driver that is easily matched to the driver actuation mechanism of the fastener drive tool and is compatible with the particular type of fastener contained within the magazine. Because of the simple structure of the magazine and the way in which the magazine is attached to the fastener drive tool, the magazine device of the present invention can be used either as a disposable magazine that can be used only once, or as a type that can be refilled and used multiple times. Also available in magazines.

In single-impact fastener-driven shells, the magazine should be rigidly secured to the shell. In multiple impact tools, the magazine must be movable relative to the tool during the fastener driving operation to accommodate the constant length of the driver and the increasingly shorter remainder of the fastener being driven into the workpiece. . In order to meet these demands,
The present invention proposes four aspects of the magazine device. 1st
In this embodiment, a plurality of different magazines containing different types of fasteners can be mounted directly to the housing of the impact tool multiple times in a sliding manner relative to the housing.

In a second embodiment, the shell housing is provided with a carrier to which interchangeable magazines containing different types of fasteners can be easily mounted. The carrier itself is attached to the tool housing. Attached to the tool housing in a sliding manner.
In this embodiment, an interchangeable magazine containing different types of fasteners is manually secured to the housing of the single-impact device. Fourth -

・The J-carrier is set up as a part of it (
A different magazine containing 11S2 different type fasteners can be manually taken out and replaced with this carrier.

The magazine device of the present invention includes a means for continuously supplying a plurality of fasteners to a driving position, a means for guiding the foremost fastener to the driving position, and a fastener driving means. The feed stage, guide means and drive means are modified depending on the type of fasteners contained in the magazine and do not form part of this invention.The fastener drive means includes a magazine driver, Means associated with the shell driver actuation mechanism are provided.

This one stage also does not form part of the present invention.

SUMMARY OF THE INVENTION According to the present invention, a manually removable and replaceable dog magazine device is provided which utilizes a fastener drive tab. The magazine device has a driver operating mechanism that drives the fastener by multiple impacts. The driver operating mechanism that drives the fastener by a single strike can also be applied to the right-hand J-type 77 snap drive shell.

Each magazine stores a plurality of fasteners and a driver for driving the fasteners. Each magazine can be manually attached to and removed from the rear of the shell housing.

In the case of multiple impact tools, the magazine is movable relative to the tool between a normally extended position and a retracted position in the housing. In one embodiment of the invention, the magazine is guided in the housing and is mounted directly to the housing in a sliding relationship.

In a second practical IM aspect of the invention, the magazine is removably mounted to a carrier provided in the tool housing in guided sliding relationship with the carrier.

In the case of a single impact, the magazine will stick to the tool housing. I can get it. In a third embodiment of the invention,
The magazine is removably attached to the tool housing (4-J) and is fixed to the tool housing with -4.
In the embodiment, the magazine is attached to the carrier 1;
The carrier is fixed to the tool housing such that it forms an integral part of the tool housing.

The magazine is a refillable and reusable magazine.
It may be a disposable magazine for one-time use. Magazines containing different types of fasteners are all interchangeable in the magazine assembly 91 of the present invention.

Part 1 of Desired Embodiments of Shoumei First, an example will be described in which the magazine device of the present invention is applied to a multiple-impact type fastener drive tool. A general description of this type of shellfish is set out in the co-pending application cited above. Briefly, this type of fastener driver is used to drive the Jζ refastener into the workpiece by applying multiple impact forces to each fastener in succession. The tool has a housing with a handle portion and a magazine portion.

The magazine is movable parallel to the longitudinal direction of the driver between a normal extended position substantially outside the tool housing and a retracted position 111 on the inside of the shell housing. (r/Means are provided for infusing the stomach.

A prime mover provides a rotating shaft operatively connected to a mechanism that converts rotational motion into reciprocating motion. The conversion mechanism includes a flywheel, an impact member, an energy transfer member engageable with the impact member, and a mechanism for extracting the energy transfer member at the end of the drive cycle. It consists of an I bumper. The impact member has at least one V! It has a single-stroke surface and is attached to the flywheel, or it is composed of one piece with the flywheel. The fastener driver is engageable by the energy transfer member.

Resilient means, usually comprised of a rubber-shaped member or a spring, bias the energy transfer member away from the impact member. When the tool is applied to the workpiece and pressure is applied by the operator, this force is overcome and the at least one impact surface of the impact member transmits an impact force to the energy transfer member, causing the energy transfer member and its associated The driver is forcibly accelerated away from the impact member at a considerable speed. This allows the driver to continuously drive short, high-speed marks into the fastener to be driven into the driving spot 1.
It starts to give 1-ri.

However, the above-mentioned type of 77 snare drive tool is suitable for home use. Compared to the normal single-impact two-impact fastener drive]-shell, the multi-impact fastener drive T-shell is actuated by a lower-power prime mover and fires one fastener over a considerable distance at a speed of 1-min. This is because it is impossible to use, is quiet, has a simple configuration, is compact, and is lightweight. When such a multi-impact type T shell is used with the magazine device of the present invention, it is very versatile and is therefore more suitable for home use. ] - The is one fastener drive tool,
Multiple different types of fasteners can be driven by simply changing the refillable or disposable magazine.

An example of a multiple impact tool is shown in FIG.

A driver actuation mechanism is not shown in FIG. 1 because it does not constitute a limiting feature of the invention. The tool 1 is equipped with a prime mover (not shown) such as an electric motor, an internal combustion engine, a hydraulic motor, or a pneumatic motor. For convenience of explanation, the shell in Figure 1 uses an electric motor as the prime mover, and this electric motor is a normal]
