Abstract

An object of the present invention is to facilitate replacement of a name tag body to be put in with a name tag attached to a chest of clothes with a pin or the like.
A back cover of a name tag, which has conventionally been a screw cover type, is formed by engaging an inward ridge provided on an inner periphery of a name plate frame with a ridge formed on an outer periphery of the back cover. 1 to reduce the amount of rotation when attaching and detaching the back cover.

Description

  The present invention relates to a name tag that can be worn on the chest of clothes with a pin or the like.

  The above-mentioned name tag has a structure in which a transparent front plate 2 is fitted to a circular frame-shaped frame 1 as shown in FIG. 4 and a back cover 3 is attached from the rear side. Is sandwiched between them. A clip 5 is attached to the back of the back cover 3.

  Conventionally, to attach the back cover to the frame 1, a method has been used in which a female screw S is cut on the inner periphery of the frame 1, and a corresponding male screw T is cut on the outer periphery of the back cover to mutually screw together.

  As described above, the mounting / detaching structure of the back cover of the conventional name tag was a screw-in type as described above, so the operation of replacing the name tag main body was troublesome. It is necessary to match the ends of the threads, and the ends of each thread match at only one place on the entire circumference, so to find that place, turn half a turn in the opposite direction to screwing in The position needs to turn the back cover, and it is surprisingly troublesome to find a position where both screws fit.

  As described above, since the attachment and detachment of the back cover is troublesome in the conventional name tag, the present invention is intended to enable the attachment and detachment of the back cover by an operation almost one-touch.

  A plurality of inwardly projecting ridges are formed in the circumferential direction on the inner peripheral surface of the name tag frame, and the length of the ridges, that is, the angle range as viewed from the center of the frame is slightly smaller than the angle range between the ridges. On the outer peripheral surface of the back cover, ridges having the same number and substantially the same angle as the ridges on the inner peripheral surface of the frame are formed in the circumferential direction of the back cover. Was formed.

  By adopting such a structure, when fitting the back cover, the ridges of the back cover are positioned between the ridges on the frame side, and the back cover is turned by the angle range of these ridges, and the back cover is rotated. The back lid can be attached to the frame by allowing the ridge on the lid side to enter under the ridge on the frame side.

  According to the present invention, when removing the back cover by replacing the name tag, etc., the back cover may be turned by the angular range of the ridge described above, and in the case of the conventional name tag, the back cover must be turned more than one turn. The operation of removing the back cover has become much easier compared to when there was none. Also, when the back cover is fitted, the ridges on the inner periphery of the frame are visible, so that the initial positioning of the back cover becomes easy.

  It is applied to a round name tag that can be worn on the chest of clothes, making it easy to replace name tags.

  1 to 3 show one embodiment of the present invention. 1 is a circular frame-shaped frame, 2 is a transparent front plate fitted to the frame 1, 3 is a back cover detachably attached to the frame 1 from behind the frame 1, between the front plate 2 and the back cover 3. The name tag body 4 is sandwiched. A clip 5 and a safety pin 6 are attached to the back of the back cover 3. The content of the invention lies in the detachable mounting structure of the frame 1 and the back cover 3.

  The back cover 3 is disk-shaped and the outer diameter is smaller than the inner diameter of the frame 1, and the overhanging edge 30 is formed outward from the back part. The lid 3 does not rattle in the frame 1. Two circumferential ridges 11 are formed on the inner peripheral surface of the frame 1 so as to fit in the gap with the back cover 3. The ridges 11 are formed in an angular range of about 70 ° with respect to the center of the frame 1, and the two ridges 11 are symmetrically arranged with respect to the center of the frame 1. Two circumferential ridges 31 are formed on the peripheral side surface of the back cover 3 symmetrically with respect to the center, and each length is about 80 ° in an angular range with respect to the center of the back cover. The height of the ridge 31 is also a height adapted to the gap between the frame 1 and the back cover 3, and when the back cover 3 is attached to the frame 1, the ridge 31 becomes the height of the ridge 11 on the frame 1 side. It is located on the lower side (this is the front side in actual use in the representation according to the figure). For this reason, when the back cover 3 is inserted into the frame 1 and the back cover 3 is turned inside the frame 1 so that the ridge 31 enters under the ridge 11 on the frame 1 side, the back cover 3 is attached to the frame 1. Can be

  Needless to say, the back cover 3 is fitted to the frame 1 as described above, and the ridge 31 of the back cover 3 is positioned between the ridges 11 on the frame 1 side (about 110 °) and the frame 1 After that, the back cover 3 may be inserted, and the back cover 3 may be turned clockwise as viewed from the back of the name tag. At this time, if the stop is not stopped, the back cover will be turned too much. To prevent this, the ridge 31 formed on the back cover 3 is located in the counterclockwise direction of the ridge 31 when the back cover is viewed from the back. The end is provided with a stopper 32 connected to the overhanging edge 30, and the ridge 31 has a flat L-shape as a whole.

  When attaching the back cover 3 to the frame 1, the clip 5 on the back of the back cover is pinched instead of the handle so that the center of the ridge 31 is positioned in the longitudinal direction of the clip 5, When the back cover 3 is inserted into the frame 1 so that the ridges 31 are positioned between the ridges 11 and the clip 5 is turned clockwise, the ridges 31 naturally fall below the ridges 11. Side, and the back cover 3 does not come off the frame 1. When removing the back cover 3, the operation may be performed in the opposite manner to the above.

  The name tags used here are round (including hexagonal, octagonal, etc.) and can be attached to the chest of the clothes with clips or safety pins, and are commonly used for identification in workplaces where many people work. The display contents of the name tag are names or numbers or symbols that indicate the contents of the person or work in charge and are often changed.There are many opportunities to replace the name tag itself, so Operation is required to be simple. Therefore, there is a great demand in workplaces, sales offices, and the like where many people engaged in various tasks work.
