Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a trowel that allows a handle to be attached to and detached from a trowel, so that old trowels can be replaced or different types of trowels can be freely replaced according to work. It is.

[0002]

[Prior art]

 In a normal iron, a handle is usually fixed to a iron plate. As disclosed in Japanese Utility Model Laid-Open No. 63-125046 and Japanese Utility Model Laid-Open No. 54-119225, a guide groove for attaching and detaching a trowel is formed on a replaceable iron that has a handle detachable from a trowel. In some cases, the handle is inserted by sliding the legs of the handle along the guide groove, or the iron plate and the legs of the handle can be replaced simply by screwing. In the conventional replaceable irons disclosed in Japanese Utility Model Application Laid-Open Nos. 63-125046 and 54-21925, it is necessary to fix a rail-shaped member serving as a guide groove to the iron plate by means such as welding. Processing is troublesome. For example, it is difficult to weld a rail-shaped member to a trowel plate such as a thin stainless steel plate, and there is a problem that distortion is caused by welding. In addition, when the leg portion of the handle is slid in the guide groove, it may slide in the opposite direction and come off.

[0003]

[Problems to be solved by the invention]

 In view of the above-mentioned drawbacks of the conventional replaceable iron plate, the present invention can easily form the mounting means for the detachable iron plate on the iron plate, simplifying the manufacturing process, and making the iron plate a thin metal plate. In the case where the iron is used, it is devised so as to provide a high-quality iron that does not cause distortion in the iron plate unlike the conventional welding type.

[0004]

[Means for Solving the Problems]

 In the present invention, the substrate 2 is fixed to the upper surface of the iron plate 1, and the handle 3 is fixed to a screw 4a protruding upward from the substrate 2 fixed to the iron plate 1. A handle 3, which is detachable from a replacement plate A in which a substrate 2 is fixed to a trowel plate 1, has a pillar 3b suspended from a grip portion 3a, and a leg plate 3c formed at the lower end of the pillar 3b is removed from the substrate. The nut (wing nut) 7 is fixed to the projecting screw 4a. The substrate 2 fixed to the trowel plate 1 is a plate material having a certain thickness, and a through hole 5 is formed at a position where the screw 4a protrudes, and a screw 4 is inserted from below the through hole 5 upward. Enter. The screw 4 prevents the screw head 4b from protruding from the lower surface of the substrate 2 when inserted into the through hole, and adheres the iron plate 1 and the substrate 2 in this state.

When the trowel plate 1 and the substrate 2 are bonded to each other with metal, a normal metal adhesive can be used, but a so-called double-sided adhesive tape can also be used. If the double-sided adhesive tape 6 used at this time is made of a cushion material as a base material 6a and an adhesive 6b is applied to both sides, an appropriate buffer effect is generated between the iron plate 1 and the handle, so that the double-sided adhesive tape 6 is used. It will be comfortable and easy to use.

[0006]

[Embodiment of the invention]

 Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view showing a state in which the replacement plate A and the handle 3 are separated. A board 2 having a fixed width and a fixed thickness is fixed in the center of the trowel plate 1 in the longitudinal direction, and screws 4a, 4a are protruded from two places of the board 2 to form a replacement plate A. It should be removable.

On the other hand, a handle 3 attached to the replacement plate A has a single pillar 3b suspended below a grip portion 3a having a shape that is easy to grip, and a fixed width and a fixed length are provided at the lower end of the pillar 3b. The leg plate 3c is fixed. In the leg plate 3c, through holes 8, 8 of a size through which the screw 4a freely passes are formed at positions corresponding to the screws 4a, 4a protruding from the substrate 2 of the iron plate 1. Thus, the screw 4a is passed through the through-hole 8, the substrate 2 and the leg plate 3c of the handle 3 are overlapped, and the nut 4, specifically a wing nut, is attached to the tip of the screw 4a protruding above the leg plate 3c of the handle 3. The replacement plate A and the handle 3 are fixed by screwing.

The process of mounting the substrate 2 on the trowel plate 1 to form the replacement plate A can be performed as follows. First, as shown in FIG. 3, the through hole 5 formed in the substrate 2 is subjected to dishing from below, and screws 4 (dish screws) are inserted from below, so that the lower surface of the substrate 2 is removed. The screw head 4b does not protrude, and the top surface of the screw head 4b and the lower surface of the substrate 2 are preferably flush with each other. When the iron plate 1 and the substrate 2 are bonded together using the double-sided adhesive tape 6 in this state, the substrate 2 is fixed to the center of the iron plate 1 as shown in FIG. Is completed, and the replacement plate A from which is projected is completed. The screw 4 to be inserted into the through hole 5 of the substrate 2 may be a screw such as a normal hexagonal head other than the countersunk screw. However, in order to prevent the screw head from projecting from the lower surface of the substrate 2, It is necessary to make a hole at the height of the screw head 4b, so that a large-thick plate material is used as the substrate 2.

When the trowel plate 1 and the substrate 2 are made of metal, the trowel plate 1 and the substrate 2 can be fixed with an adhesive for metal, and when the trowel plate 1 and the substrate 2 are made of other materials, an appropriate adhesive can be used. In the illustrated embodiment, a double-sided adhesive tape 6 is used. The double-sided adhesive tape 6 preferably has a cushion material as a base material 6a and adhesives 6b, 6b applied to both surfaces thereof. This makes it possible to stabilize the screw 4 even if the top surface of the screw head of the screw inserted into the through hole does not exactly coincide with the lower surface of the substrate 2, and a buffer effect is provided between the iron plate 1 and the handle. This has the effect that the shocking external force generated on the mortarboard during work is difficult to transmit to the hand.

The iron plate has various shapes according to the type of work, and various types of iron plate materials are used, from thin metal plates to synthetic resin plates. The structure of the present invention can be used in common with all irons by setting the screw 4a for mounting in common with iron plates of various shapes and various materials. This means that a worker can use a familiar handle on a different type of iron and use it, and also use a new replacement plate on a familiar handle when the same iron plate becomes old. Becomes possible.

[0011]

[Effect of the invention]

 According to the replacement plate type iron according to the present invention, a replacement plate in which a substrate is fixed to an arbitrary iron plate and, for example, an arbitrary handle that is familiar to the user can be easily combined and used. However, there is a feature that it can be manufactured by a simple process of bonding a substrate to a trowel plate. In addition, when manufacturing the replacement board, since a heating means such as welding is not used to fix the board to the iron board, it is possible to provide a high-quality product without causing distortion or the like even for a thin iron board. .

According to the second aspect of the present invention, the iron plate and the substrate can be more easily fixed, and the top surface of the screw head mounted on the substrate and the lower surface of the substrate do not need to be exactly aligned. In addition to being acceptable, the base material of the double-sided adhesive tape exhibits a buffering effect, and the impact generated on the iron plate is not easily transmitted to the handle, so that it is possible to provide an iron that is easy to use without fatigue.
