DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magazine mechanism for a tucker which accommodates connected staples and supplies the staples to an ejection section in order from the first one.

[0002]

2. Description of the Related Art In general, a tucker is used to drive a U-shaped staple into a material to be driven, and is used for upholstering a chair, a bed or the like, or fastening a lath net to a wall material. The staples are stored and arranged in a magazine in the form of a connected staple in which a plurality of U-shaped staples are adhesively connected, and the magazine is configured to supply the leading staple one by one to the ejection portion of the tucker body each time the staple is driven. I have.

[0003] By the way, this type of tool tends to be reduced in weight, and also in a tucker, the number of parts is reduced, and heavy metal parts are made of synthetic resin to reduce the weight and improve workability. Attempts have been made to try. It is difficult to reduce the number of parts because it leads to changing the structure. It is more feasible to use metal parts made of synthetic resin. In this case, a component that has a relatively high proportion in the whole and does not require much strength is suitable. Therefore, the main function is to store the staples and supply them to the ejection unit, and a magazine having relatively low strength is preferable.

[0004]

However, when the first staple of the connected staples is ejected, the first staple is separated from the second staple, but since both staples are adhered by an adhesive, the adhesive is cut. At the time, a force is applied to the second and subsequent connecting staples in the launching direction, and a large load is applied to the member holding the connecting staples.If the above member is made of synthetic resin, the strength and rigidity are insufficient, There has been a problem in that the members are deformed, which hinders the staple supply and impairs the durability.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a magazine mechanism for a tucker that solves the above-mentioned problems, can reduce weight and improve operability, and has sufficient strength and rigidity.

[0006]

In order to solve the above-mentioned problems, a magazine mechanism in a tucker according to the present invention has a storage groove for internally storing a connecting staple so as to be slidable in a longitudinal direction, and a front end of the storage groove is provided. For a magazine that is opened to an ejection portion formed in the main body of the tucker, a slider that enters the storage groove and holds a staple inside by slidably disposed along the storage groove is provided. In addition to being made of synthetic resin, a hook-shaped reinforcing arm is formed to project from an end on the side of the injection section, and a tip of the reinforcing arm is engaged with an engagement hole formed in the injection section. I do.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a magazine mechanism of a tucker, and this magazine mechanism is connected to a driver guide 2 constituting an ejection section 1 formed on the main body of the tucker. As shown in FIG. 2, the driver guide 2 is formed with a concave sliding guide groove 4 for guiding the driver 3 driven in the vertical direction by the hitting mechanism of the tucker body.

The magazine mechanism comprises a magazine 5 and a slider 6. As shown in FIGS. 2 and 3, the magazine 5 has an inverted U-shaped housing in which a connecting staple 7 is slidably held in the longitudinal direction. A staple storage section 9 having a groove 8 and a flange plate 10 projecting outward from the front end of the staple storage section 9 at right angles;
0 is in contact with the driver guide 2 and the sliding guide groove 4
And an end of the storage groove 8 is opened to the sliding guide groove 4. The staple storage section 9 is formed in the staple storage section 9 along the longitudinal direction from the open end of the storage groove 8 to the side. A rib-shaped guide rail 11 is formed so as to protrude. The injection unit 1 includes a driver guide 2 and a flange plate 10. Engagement holes 22 are formed on both left and right sides of the flange plate 10. Reference numeral 12 denotes a lock release lever.

Next, a slider 6 which enters the storage groove 8 and holds the connecting staple 7 in the storage groove 8 is slidably disposed along the storage groove 8 with respect to the magazine 5.

The slider 6 is formed by fixing a pair of left and right slider 6 members 6a and 6b made of synthetic resin with a staple guide 13 interposed therebetween.
As shown in FIG. 3, a and 6b are bent in a U-shape in cross section, and an engagement groove 14 that opens inward along the longitudinal direction is formed on the inner upper side. A plurality of holes 16 are formed at equal intervals along the length. A hook-shaped reinforcing arm 17 is formed at one end of each of the slider members 6a and 6b. The staple guide 13 is a plate-shaped member made of synthetic resin or metal (for example, iron), and has a thickness substantially equal to the dimension between the legs of the connecting staple 7 to be used. The slider member 6 is provided at the lower end.
A plurality of holes 18 are formed so as to correspond to the holes 16a and 6b. A top block 19 is attached and fixed to the tip of the staple guide 13.

The lower end of the staple guide 13 is sandwiched between the elongated plate portions 15 at the lower ends of the slider members 6a and 6b, and the rivets 20 are inserted into the corresponding holes 16 and 18 to be integrally connected. A slider 6 is configured. A cap 21 is fixed to an end of the slider 6 on the side opposite to the ejection section 1 side.

The engagement groove 1 facing the inside of the slider 6
Guide rails 11 on both sides of the magazine 5 are engaged with 4. As a result, the slider 6 becomes slidable along the guide rail 11, and the upper part of the staple guide 13 enters the inside of the storage groove 8 of the magazine 5,
Is formed between the inner surface of the staple guide 13 and the outer surface of the staple guide 13. In addition,
A staple pusher (not shown) is arranged on the staple guide 13 and is biased by a spring toward the ejection section 1.

In the above configuration, when loading the connected staples 7 into the magazine 5, the lock release lever 12 unlocks the slider 6 and slides the slider 6 rearward as shown in FIG. As a result, the lower portion of the storage groove 8 of the magazine 5 is opened, so that the opening portion of the storage groove 8 is turned upside down, the connecting staple 7 is loaded from here, and the slider 6 is moved again to move the storage groove. What is necessary is just to close the lower part of 8. The slider 6 is locked at the moving end.
7 is the engagement hole 2 of the flange plate 10 of the magazine 5
2.

Next, the leading staple 7a of the loaded connecting staple 7 is supplied to the sliding guide groove 4 of the driver guide 2 of the injection section 1 by the pusher, and thereafter the driver 3 is moved downward as shown in FIG. When the first staple 7a is driven and hit, the first staple 7a is separated from the second staple 7b and is ejected from the ejection unit 1 as shown in FIG. By the way, since the first staple 7a and the second staple 7b are bonded by an adhesive, the adhesive is cut when separated, but at this time, the second and subsequent connecting staples 7 also have a large size in the launching direction. Power is added. Since this force is also transmitted to the staple guide 13 of the slider 6, a large load is applied to the slider 6. On the other hand, as shown in FIG. 1, since the reinforcing arm 17 is engaged with the engaging hole 22 of the flange plate 10 of the magazine 5 to reinforce the slider 6, even if a force in the ejection direction is applied to the slider 6. , Does not deform. Since the slider 6 is not deformed, the connection staples 7 are properly stored in the storage grooves 8 and guided and supplied to the ejection section 1 smoothly and reliably.

As described above, since the slider 6 is made of a synthetic resin, the weight is reduced and the slider 6 can be operated lightly. Further, since the tip of the reinforcing arm 17 of the slider 6 is reinforced by being engaged with the engaging hole 22 of the magazine 5, a sufficient strength and rigidity can be obtained as a whole, and a load is applied to the slider 6 at the time of driving. Is not deformed, and the durability is not impaired.
