Description

DETAILED DESCRIPTION OF THE INVENTION The present invention generally relates to a novel magazine assembly for fastener driving tools, in which the fasteners are shaped or rotated within the tool nose piece. Is the magazine quick and effective when it gets wet? It is possible to open the tool according to wear and prevent the tool from operating when there are no fasteners in the magazine.

Various fastener driving tools are well known in the industry. These tools include pneumatically and electrically operated tool scales as well as other quiffs, which are linked together! It is intended to be operative and therefore includes a machining mechanism that holds a large number of fasteners. The magasine is arranged to introduce one fastener in sequence into a fixed position. Mizuta + work No. 3,207,405 and No. 3,815,47 where the rights to the present invention are exemplified and have a + mark
Various types of magazines such as those shown in No. 5 have been adopted. Although these magazines function satisfactorily,
Unfortunately, blockages can occur due to bent nails or other foreign objects. The resultant side can build up within the nose piece of the tool, interfering with its operation.

Of course, it would be desirable to provide a simple and inexpensive mechanism to allow magazine disassembly to quickly remove stuck fasteners. Another desirable characteristic to be included in an automatic fastener driving tool is the presence of a mechanism that can alert the operator to the relatively small number of nails remaining in the magazine and therefore the fact that reloading the magazine is a no-go. . This feature clearly matches the operating efficiency of the tool and will eliminate problems that may arise from firing the tool when the magazine is empty. Additionally, it would be desirable to provide a reliable mechanism to prevent incorrect operation of the tool. Such a feature that prevents the tool from activating also saves fuel and reduces the possibility of having only one or two fasteners in the magazine and losing control of them when reloading. The gloves can also be locked for tool transport.

In accordance with the present invention, a novel magazine is provided that includes a magazine portion that provides an interpolation path for the fasteners to be driven. This magazine is attached to the nose portion of the main body of the tool and cannot be easily moved relative to the barrel, so that the pick-up fasteners inside can be easily pulled out.

In addition, it is necessary to control the activation of workpiece-sensitive nolobe assemblies and to prevent the tool from activating at a time when it is not desired or when only a few fasteners remain in the magazine. A machine is provided. This allows the follower, which normally acts to bias the secondary into position within the nose piece, to automatically contact the lockout bracket when desired or when only a few nails remain in the magazine. is achieved. When the lockout bracket is moved into position, the workpiece of the sensitive glove assembly! The fastener stops moving, thus preventing the tool from igniting, and immediately alerts the operator that the fastener is running out and should be refilled. Once the fastener is loaded, the follower is retracted and the lockout bracket, which is normally biased to the disconnection position, is removed from contact with the workpiece sensitive glove and normal operation of the tool is permitted. Ru.

The present invention will be described in detail below with reference to the accompanying drawings.

Reference is now made to FIG. 1, which schematically shows a fastener driving tool powered by pressure generated by the combustion of a fuel and air mixture. This type of tool is shown for example purposes only. This is because the novel magazine assembly disclosed herein can be employed in various types of fastener driving tools, including those that are pneumatically and electrically actuated. Only the general details relevant to the invention of the tool will be dealt with here.

For more detailed information on the illustrated tools, please refer to the book "Gas Powered Portable Fastener Driving Tool".
(filed on July 28, 1982, No. 402,770).

The types of tools to which the invention applies include tools that are successively brought into driving position to be driven into the workpiece by a driver attached to a drive piston actuated by air, combustion gas or other energy source. Tools are included in which a magazine adapted to house a plurality of fasteners, such as biased nails, is attached to the tool.

As briefly mentioned above, the present magazine assembly has several novel features. That is, (1) a mechanism that makes it possible to easily remove the magazine assembly from the nose portion of the tool and remove a fastener stuck in the nose piece;
2) It is a mechanism that prevents the tool from activating when it is not desired or when there are only a small number of fasteners in the magazine, i.e. only 4 to 6 fasteners. Regarding the first feature, that is, the magazine can be easily opened to remove a sword stuck in the nose piece, when the fastener driving tool comes into contact with the nose piece or the object to be touched, There is no need to include a workpiece sensitive probe assembly in order for the same tool to work. However, another important feature of this magazine is that it prevents the tool from operating when there are only a few fasteners left in the magazine! These two classes are illustrated for the same two units since the signature is combined with the workpiece sensitive flow assembly. + ~ Regarding the workpiece-sensitive Frozen assembly, there is no interaction with the assembly details and tool operation! This means that it is not a matter of small trade. That is,
There are only a few fasteners left in the magazine, which prevents the tool from working! Indications are that if the prerequisite is that the subcutaneous usurer's glove assembly contains a cap that moves against the nose piece when the bird is activated to ignite the tool, It means that it will be done. Thus, the novel lockout mechanism can be used with any one of several structures, sometimes referred to as a glove assembly or a "bottom trip mechanism."

next! Referring to Fig. 1, the main body part 1 is shown in the same figure.
A fastener driving denting tool 12 is shown having a handle portion 16 as well as a handle portion 16. +Reporter body? A nose cold part 18 is arranged below the part 14, and the handle part 1
From 6 downwards! A foot portion 18 is provided on the frame.

There are 24 hook strips inside the magazine,
The shaver is biased via follower 26 to a position within the nosepiece. The conventional constant force between the followers is biased against the moving strip by a straw stand 28.

It is activated by activation of the above-mentioned tool + trigger 30, and the trigger is activated! The floating of the piston 32 and associated drive blade 34 extending entirely through the nodal piece 12 is activated. The operation of the trigger 30 is controlled by a workpiece-sensitive (acting in response to the workpiece) knob assembly 36.

In this tool, the bird 30 cannot be operated unless the trigger lock assembly 38 is moved upwardly by the workpiece trigger assembly or the nose piece 18 to open the trigger-in lock assembly 38. . The details of the assembly 38 are important to fill in, but if you wish to obtain information regarding the interrelationship between the columns and the workpiece-sensitive glove assembly, please refer to the description below. Please refer to the specification (Gas-powered portable fastener driving tool, serial number 402,770).

As mentioned above, the novel lockout mechanism of the magnifier shown here is subject to the condition that the trigger cannot be activated unless the flow introducer moves a predetermined amount relative to the nose assembly. If the probe assembly is sensitive to workpieces, it can be used in conjunction with any of the trigger-in clock mechanisms that have been considered. Similarly, the trigger mechanism shown here is designed to operate the tool using gas ignition, but the same trigger mechanism also controls the bullet mechanism to introduce high pressure air and push the piston. It can be used for driving, or it can be used to create electrically controlled tools! You can also use it to control. The force used to drive the piston is decisively moderate as long as the bird controls the application of such force.

Referring now to FIG. 2, there is shown an enlarged view of the magazine, the main portion of the magazine being indicated by a pair of bins 40 relative to the nose piece. The bottle is solid! The opening shaped inside the nose guide 18 (plural)
It extends inward (only one hinge and opening is illustrated).

The machine is loaded with a fastener 24, and a small mover 2
6 is in the retracted position as shown in FIG. 5B.

The rear end of the machining tool is supported relative to the foot portion 20 of the driving tool handle 16 by interdigitating serration teeth 44,46. The narration teeth are formed on members 45 and 47 attached to foot portion 20 and magazine 22, respectively (see FIG. 3). The serration threads 44, 46 are held in locking alignment by a threaded nof assembly 50 and associated nut 52. The foot portion 20 defines an elongated groove 54 within which the knob introduction body 50 can move freely. Knob 5 as shown in Figure 6
Once the teeth have been loosened and the teeth are in a distal position, the magazine 22 can be moved to the right to the position shown in FIG. In this position, there is a gear horn 56 between the nose guide portion and the proximal end of the magazine that can be moved relative to the magazine and associated pin 40, resulting in a jam. It will be understood that it is possible to exclude fasteners. Once the fastener has been removed, move the magazine to the left and press + cut knob! By tightening the three-dimensional body, it is possible to reinstall the serrations and lock the magazine in place near the nose guide.

As shown in Figure 2, there are fruits in the magazine! Is there a certain number of fasteners? The heel assembly 26 is substantially retracted from the nose of the tool in the configuration shown in FIG. 5B. In the picture where the fastener is no longer used, the follower assembly 26 - due to the action of the foot force spring 28, a small amount of the fastener remains? Move the rail 58 forward until it ends in the position shown in FIG. 4 (see FIG. 5). It is at this point that the follower 2G engages the lockout bracket 60 and the action of the bracket prevents the tool from being "locked out" or struck from being ignited. The bracket 60 is fixed to the magazine by a fastening member 63 extending through a long and narrow slot 68 in the bracket. The bracket 60 is freely movable relative to the fastening member 63 and is bent downwardly to connect the contact member (not shown) on the magazine and the lockout racket.
Normally, it is maintained in the position shown in FIG. When the follower 26 engages the 7 langes 64 of the lockout prout, the same bracket moves against the spring 61, and the end 65 of the lockout bracket is attached to the tubular broken work piece as a metal body. Then, it contacts the nose piece directly above the probe material 66.

When in the engaged position with the bracket or nosepiece, the probe 66 is moved into the nose a sufficient distance so that the bird opens the lockout mechanism 38 and the trigger 30 is activated to fire the rigging. It is only possible to move relative to one piece. The lockout bracket thus prevents operation of the fastener tool when only a few fasteners remain in the magazine.

Referring now to FIGS. 5A and 5B, two positions of the subordinate body 26 are illustrated in these figures. Fifth
In figure A, the follower is hyperactuated to avoid the struts, and the constant force spring brings the core into contact with the long out bracket! Rather than move, there was a nail inside the macajin to prevent it from igniting. This is done when it is desired to lock the probe in place when it is not being transported or used.

In Figure 5B, do you see the nail being biased to the position where it should be driven? ! Child 26 is shown.

In this mode of operation, the lockout placket is kept in contact until only a few hooks are left in the magazine.

Of course, the claims are intended to cover the core spirit of the invention and all embodiments thereof.
