Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a winding core for a tape measure case.

(Prior art) In general, the winding core of a tape measure case has a hook pin that fixes a ring portion formed at the end of the tape measure, and a hook for winding the tape measure on the circumferential side thereof, and a hook that is integrally attached to the hook. It is composed of a handle connecting plate that is fitted into the handle and rotates together with the tyco. In addition, tape measures mainly include textile tape measures and steel tape measures.As shown in Fig. 2, the textile tape measure 3 has a wide ring part 7 at its end.
Further, as shown in FIG. 6, the ring portion 16 at the end of the steel tape measure 15 is formed narrowly. The hook pin 9 is relatively long, and the hook pin 18 of the tycoon 14 for the steel tape measure 15 is relatively short, as shown in FIG.
For this reason, in the tycoon 4 for the textile tape measure 3, the wall thickness of the base 8 on which the hook pin 9 is protruded is relatively small, and in the tycoon 14 for the steel tape measure 15, the wall thickness of the base 17 on which the hook pin 18 is protruded. The thickness is relatively large. By the way, in the past, after a tape measure was manufactured, it was manually wound and stocked, and after the winding core was attached to the case body, the tape measure was unwound and then wound again around the winding core. As a result, the assembly process was extremely wasteful.

(Problem to be solved by the invention) This invention automatically winds up a tape measure around the winding core using a winding machine, stores the tape measure wound around the winding winding, and attaches it to the case body. The purpose of this is to streamline the process by allowing the tycoon with the tape measure wrapped around it to be assembled into the case body as it is.

(Means for Solving the Problems) In order to achieve the above object, the winding core of the tape measure case of the present invention has a hook pin for fixing the ring portion at the end of the tape measure, and the tape measure case is provided on the circumferential side of the core. By providing a hole into which a mounting pin protruding from the jig rotary plate for the winding machine of the tape measure can be inserted, automatic winding is possible, and the tape measure can be stored with the tape wound wound. It consists of a tyre, which can be assembled into the case body as is, and a handle connecting plate, which can be fitted integrally with the tyre, and has a protruding insertion pin that can be inserted into the above-mentioned hole provided in the tye.

In addition, the base with protruding hook pins for textile tape measures has a small wall thickness as mentioned above, so it can be easily used when automatically winding up with a winder or when used after being assembled into the case body. There is a concern about the strength of the pin breaking, but in order to eliminate this concern, the above-mentioned hole is drilled in the center of the hook pin in the fiber tape measure tie, and the hook pin is shaped like a cylinder. It is preferable that the hook pin be reinforced by making it possible to insert a mounting pin protruding from the winder jig rotary plate or an insertion pin protruding from the handle connecting plate into the hole.

Further, although the structural differences between the fiber tape measure tie and the steel tape measure tie are unavoidable, it is advantageous to use a common handle connecting plate that is integrally fitted with these ties. However, since it is necessary to provide an insertion pin on the handle connecting plate in order to reinforce the hook pin of the fiber tape measure as described above, this insertion pin becomes a hindrance. Therefore, in order to release the insertion pin protruding from the handle connection plate, it is possible to insert an insertion pin into the tyco for the steel tape measure at a location other than the hook pin (of course, it is possible to insert the insertion pin protruding from the jig rotating plate for the winder). It is preferable to provide the above-mentioned hole portion into which the material can be inserted.

(Example) An example will be described below with reference to the drawings.
First, FIGS. 1 to 5 relate to a winding core for a fiber tape measure. FIG. 1 is an exploded view of a tape measure case, which consists of a winding core 1 and a pair of case bodies 2, 2' to which the winding core 1 is sandwiched and attached.
Furthermore, the winding core 1 is composed of a ring 4 for winding the tape measure 3 on its circumferential surface, and a handle connecting plate 6 to which a handle 5 is attached and is integrally fitted with the ring 4. As shown in FIG. 2, this tie rod 4 has a relatively long hook pin attached to a relatively thin base 8 in order to fix a wide ring part 7 formed at the end of the fiber tape measure 3. 9 is provided protrudingly. As shown in FIG. 3, a winding machine jig rotary plate 10 can be fitted onto the inner surface of the winding machine 4, and the tape measure 3 is wound around the circumferential side of the winding machine 4. It is automatically wound up by a take-up machine. Therefore, it is possible to store the tape measure 3 wound around the tyre 4, and when assembling the tape measure 3 onto the case body 2, 2', the tye 4 with the tape measure 3 wound thereon can be assembled as is. A mounting pin 11 is provided protruding from the winding machine jig rotary plate 10, and a hole 12 into which the mounting pin 11 can be inserted is opened on the inner surface of the tycoon 4 at the center of the hook pin 9. The hook pin 9 provided is cylindrical. Therefore, when the winding machine automatically winds up the tape measure, the mounting pin 11 is inserted into the hole 12 of the hook pin 9 for reinforcement, so even if the wall thickness of the base 8 of the tyco 4 is small, the hook pin 9 will not break. There is no risk of it happening. As shown in FIG. 4, an insertion pin 13 that can be inserted into the hole 12 provided in the hook pin 9 of the above-mentioned tyco 4 is protruded from the inner surface of the handle connecting plate 6 that is integrally fitted with the tyco 4. has been done. Therefore, even when the tycoon 4 and the handle connecting plate 6 are integrally fitted and assembled to the case bodies 2, 2' for use, they can be inserted into the hole 12 of the hook pin 9 as shown in FIG. The pin 13 is inserted and the hook pin 9 is reinforced.

Next, FIGS. 6 to 8 relate to a winding core for a steel tape measure. The tycoon 14 has a narrow ring portion 16 formed at the end of a steel tape measure 15 as shown in FIG.
A relatively short hook pin 18 is provided protruding from the relatively thick base 17 in order to fix the winder jig rotation plate 10 on the opposite side of the hook pin 18. A hole 20 into which the mounting pin 11 can be inserted is provided. This Tyco 14 has the 7th
As shown in the figure, the same handle connecting plate 6 that can be fitted with the above-mentioned fiber tape measure tycoon 4 can be fitted,
As shown in FIG. 8, the insertion pin 13 protruding from the handle connecting plate 6 is designed to be able to be inserted into the hole 20 and escaped in a state where the pin 14 is fitted.

(Operation and Effect) The present invention is as described above, and first, by configuring as claimed in claim 1, a jig rotary plate for a winding machine is attached to the winding machine, and the winding machine automatically attaches a tape measure to the winding machine. Since it is possible to assemble the tycoon with the tape measure wrapped around it when winding and storing it and assembling it into the case body, there is an effect that rationalization of the process is achieved. By doing this, the attachment pin for the jig rotary plate for the winding machine is inserted into the hook pin for the textile tape measure when the tape measure is being wound up, and the insertion pin for the handle connecting plate is inserted into the inside of the hook pin for reinforcing the tape measure. This has the effect of preventing the hook pin from breaking, and furthermore, by configuring it as described in claim 3, the handle connecting plate that fits into the tie for a textile tape measure can also be used for a tie for a steel tape measure. As a result, parts can be standardized, resulting in cost reduction and other effects.
