Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an improvement of a rotary rubber stamp.

(Prior art) A bridge piece is stretched between the lower ends of a frame with a handle, a plurality of rotating elements are arranged in parallel in the middle of the frame, and an endless printing belt is suspended between each rotating element and the bridge piece. Rotary rubber stamps equipped with a rotary rubber stamp are widely used for date stamps, etc., but conventional rotary rubber stamps do not work even if the rotor is operated to place the printing parts directly below the bridge piece in parallel. If the rotator or printing belt touches anything else, the printing belt will move and the desired alignment will not be obtained. Therefore, Jikosho developed a rotary rubber stamp in which a column frame was attached to the front of the frame in such a way that the column claws provided at the bottom of the frame were engaged with the grooves formed between each printing section of the printing belt. It has already been proposed as seen in Publication No. 30-3505.

(Problem to be solved by the invention) However, since the column frames in conventional rotary rubber stamps of this type are usually riveted to the frame at the base ends of both arms, once the assembly is completed, In this case, the printing belt cannot be replaced, and the engagement between the row claw pieces and the groove of the printing belt can only be maintained by engaging the hook at the tip with a pin protruding from the frame. There is a risk that the hook may become disengaged from the pin for some reason during use, and the alignment function is insufficient.Furthermore, it is difficult to tack the alignment frame to the frame or protrude the pin. This is a time-consuming process.

(Means for Solving the Problems) The present invention relates to a rotary rubber stamp that solves the above-mentioned problems, in which a bridge piece is stretched between the lower ends of a frame with a handle, and a plurality of rubber stamps are installed in the middle of the frame. In a rotary rubber stamp in which rotators are arranged in parallel and an endless printing belt is suspended between each rotator and a bridge piece,
A top plate with short shafts protruding from both sides and a spring receiver in the front is attached to the lower surface of the top plate of the frame, and the tips of both short shafts are passed through holes made through the respective side panels of the frame. A square frame for columns is made to protrude to the outside, and the front side of the frame is provided with a column claw piece that engages with the printing belt at the lower end, and a column corner frame is provided with a tongue piece for operation on the upper edge through the square window hole. Each shaft hole of a bearing piece provided rearward on both sides of each rotating element in a protruding state is removably engaged with the tip of both short shafts, and is characterized by being equipped with a spring that always springs the upper side of the square frame for rows forward.

(Embodiments) Next, the present invention will be described in detail with reference to illustrated embodiments.

1 is a handle attached to the center of the top side of the gate-shaped frame 2, 3 is a bridge piece stretched between the lower ends of the frame 2, and 4 is a plurality of pieces rotatably arranged in parallel in the middle of the frame 2. With rotators, each rotator 4 and bridge piece 3
An endless printing belt 5 is suspended between them, and the above structure is no different from a conventional rotary rubber stamp. Reference numeral 8 denotes a top plate attached to the lower surface of the top plate of the frame 2, which has short shafts 6 protruding from both sides thereof and a spring receiver 7 at the front. are made to protrude to the outside through holes 10 provided through each side plate portion of the frame 2. Reference numeral 11 denotes a square frame for columns attached to the front surface of the frame 2 with each rotator 4 protruding from its corner window hole;
Reference numeral 1 denotes a row claw piece 9 which has an operating tongue piece 11a stretched on its upper edge and engages with the printing belt 5 on its lower edge.
Bearing pieces 12 facing backward are provided on both sides of a rectangular frame-shaped main body with Further, a spring 14 is attached to the spring receiver 7 so as to always spring the upper side 11' of the square frame 11 forward. 1
Reference numeral 5 designates a central hole provided through the top plate 8 as a means for attaching and fixing the top plate 8 to the lower surface of the top plate of the frame 2. A screw 16 is inserted into the center hole 15 and attached to the top plate of the frame 2. It is fixed by screwing a screw 16 into the lower surface of the handle 1 through a transparent hole 17, and 18 is a notch provided in the top plate 8 in the front-rear direction as necessary. Reference numeral 18 imparts lateral elasticity to the top plate 8, and this elasticity allows the short shafts 6 to engage with holes 10 provided through each side plate portion of the frame 2. When one or both of the holes 10 are cut out over the front edge of the side plate portion of the frame 2, the notch 18 is not necessarily provided.

(Function) The device configured in this way has the operating tongue piece 11.
By pushing a against the elastic force of the spring 14, the column square frame 11 is slightly pivoted about the short shafts 6, 6, and the printing belt 5 can be fixed by the column pawls 9. Then, by operating the rotator 4 protruding from the square window hole of the column square frame 11, the bridge piece 3 stretched between the rotor 4 and the lower end of the frame 2 is removed. Rotate the endless printing belt 5 suspended on the
Required printing portions 5 of the printing belt 5 are arranged in parallel directly below the bridge piece 3. Next, the pressure on the operating tongue piece 11a is released and the elastic force of the spring 14 is used to return it to the old state, and the printing belt 5 is fixed by the character claw piece 9, and then the handle 1 is gripped and stamped. However,
During the stamping operation, the printing belt 5 with the required printing parts 5 arranged in parallel directly under the bridge piece 3 has the printing parts 5,
The rowing claw piece 9 at the lower end of the rowing square frame 11 is engaged with the groove between the rows of square frames 1 and 5.
Since the upper side 11' of 1 is always springed forward by the spring 14, the row claw pieces 9 fix each printing belt 5 at the same time, and the rotating element 4 and the printing belt 5 are prevented from being touched by other objects during stamping. There is no risk that the printing belt 5 will move and disturb the characters even if touched. In addition, the short shafts 6, 6, which are the pivots of the square frame 11, and the spring 14, which presses the claws 9 of the square frame 11 against the printing belt 5, are attached to the lower surface of the top plate of the frame 2. Since they are provided on both sides of the attached top plate 8 and on the spring receiver 7 provided in front of the top plate 8, one top plate 8 and the spring 14 are incorporated into a normal rotary rubber stamp. A short shaft 6 is provided protruding from both sides of the top plate 8 with shaft holes 13, 13 in bearing pieces 12, 12 provided rearward on both sides of the square frame 11 for rows from the outside. , 6 in a removable manner, the number of parts is small, and the assembly work is easy. Moreover, the square frame 11 for the columns is attached to the short shafts 6, 6 after the rotary rubber stamp main body is assembled. Since it can be easily removed by simply disengaging the shaft holes 13, 13, the printing belt 5 can also be replaced. moreover,
The spring 14 is located on the back side of the column square frame 11 and is not exposed to the outside, so the appearance is good. Further, even when the short shafts 6, 6 are loosely inserted into the holes 10, 10 and the shaft holes 13, 13, the spring 14 always springs the upper side 11' of the square frame 11 forward. Therefore, there is no risk that the square frame 11 for rows will separate from the frame 2 due to impact. Note that the spring receiver 7 provided in front of the top plate 8 and the spring 1 attached thereto
4, as shown in FIG. 1, is not limited to protrusions and coil springs protruding from the front surface of the top plate 8 made of synthetic resin, etc., and as shown in FIG. A concave portion is formed by leaving a protrusion on the front upper surface of the spring receiver 7, and a locking end of a filigree spring serving as the spring 14 is engaged with the thin line between the protrusion and the inner surface of the concave portion to form an intermediate portion. Upper side 1 of column square frame 11
1', or as shown in FIG. 4, locking rings at both ends of the wire spring 14 are attached to the protrusions of the spring receiver 7 similar to the spring receiver 7 shown in FIG. 3. By locking the middle part is the square frame 11 for rows.
Alternatively, as shown in FIG. 5, a protrusion may be left at one end of the front surface of the top plate 8 to form a concave portion to serve as a spring receiver 7, and a spring 14 may be attached to this protrusion. Of course, one end of the leaf spring may be engaged and fixed so that the free end of the leaf spring is in contact with the upper side portion 11'.

(Effect of the invention) As is clear from the above description, the present invention is capable of fixing the printing belt by the square frame for rows, using the short shafts provided on both sides of the top plate as pivot points, and moving the belt forward above the square frame for rows. Because it is due to the elastic force of the spring,
It has an excellent column function that allows the printing area to be always stamped to be held in parallel at a predetermined position directly below the bridge piece, allowing for clean stamping.In particular, the square frame for the column is stretched over its upper edge. By simply pushing a certain operating tongue piece lightly against the elastic force of the spring described above, the lower end rowing pawl piece is easily pivoted forward and away from the printing belt using the aforementioned short axis as a pivot point. Therefore, when you want to unfix the printing belt, simply place the thumb of the hand that is gripping the handle on the operating tongue and press lightly against the elastic force of the spring to fix the printing belt. The operation is extremely simple and the printing belt can be easily rotated.Since the rotating element protrudes from the square window hole of the square frame for columns, the square frame for columns can be rotated easily. Coupled with the fact that this does not pose any hindrance to the movement of the printing belt, it becomes extremely easy to operate the rotator for rotating the printing belt. Furthermore, a top plate with a short shaft that serves as the axis of the square frame for rows and a spring holder is attached to the lower surface of the top plate of the frame, so that the square frame for rows and the spring can be attached using this top plate. Therefore, it is easier to manufacture than the conventional method, in which the column frame is riveted to the frame and the hook at the end engages with a pin protruding from the frame. Furthermore, the column square frame is rotated by removable engagement between the shaft hole of the bearing piece provided rearward from both sides and the short shaft protruding from both sides of the top plate. Since it is assembled on the outside of the rubber stamp body, the square frame for the rows can be easily attached and detached, making it convenient to assemble and replace the printing belt, and has various advantages. Coupled with the advantage that it can be provided at a low cost due to its simplicity, it has great practical value as a solution to the problems of conventional rotary rubber stamps.
