Embroidery hoop

Abstract

This article is an embroidery frame that holds a cloth in a taut state when embroidering the cloth. As shown in the "Reference Diagram Showing the Names of Each Part," this article includes a pair of vertical frames that are spaced apart from each other and extend in the front-rear direction, and a pair of horizontal frames that are spaced apart from each other and extend in the left-right direction. The vertical frames are formed with long holes that extend in the front-rear direction at two locations, one at the front and one at the back, penetrating from top to bottom. The horizontal frames are formed with grooves at the top and bottom of both left and right ends. A bolt insertion hole is formed in the center of the groove. The horizontal frames are provided with a cloth tape between the left and right grooves. The front and rear ends of the cloth to be embroidered are temporarily sewn onto the cloth tape before use. The left and right grooves of each horizontal frame are fitted into the left and right vertical frames. The embroidery frame can be assembled by fitting any one of the grooves provided at the top and bottom of the horizontal frames into the vertical frames. The vertical and horizontal frames are fixed together in a state where the horizontal frame is slid in the longitudinal direction (i.e., the front-rear direction) of the vertical frame to stretch the cloth. This fixing is achieved by passing the shaft of a bolt through the long hole of the vertical frame and the bolt insertion hole of the horizontal frame from below the embroidery frame, and screwing a knob nut into the tip of the bolt from above the embroidery frame. By fitting the groove of the horizontal frame into the vertical frame, a square frame can be formed with the vertical frame and the horizontal frame intersecting at a right angle. Therefore, the embroidery frame does not warp during use, and the cloth can be securely held in a taut state. When it is desired to embroider a cloth longer than the length of the vertical frame, the cloth can be wrapped around the horizontal frame and the embroidery work can be carried out while shifting the embroidery part little by little. At that time, as described above, the grooves are formed on the top and bottom of the horizontal frame, so that the grooves on both the top and bottom of the horizontal frame can be fitted into the vertical frame. In other words, the horizontal frame can be fitted into the vertical frame every half turn. This allows the tension of the fabric to be easily and flexibly adjusted. After that, the horizontal frame is slid outward in the front-to-rear direction relative to the vertical frame, and with the fabric stretched, it is fixed with the bolts and knob nuts. Furthermore, as shown in "Reference Oblique View 2 Showing the State of Use," it is preferable that the left and right sides of the fabric to be embroidered are also held by the belt fabric wrapped around the vertical frame. Note that "Reference Oblique View 1 Showing the State of Use" shows the state in which the rear horizontal frame has been rotated once (360 degrees) and the rear end of the fabric is wrapped around the horizontal frame.In addition, "Reference Oblique View 2 Showing the State of Use" shows the state in which the front horizontal frame is rotated once (360 degrees) and the front end of the cloth is wrapped around the horizontal frame. The parts for which the design registration is sought are the left and right ends of the front and rear horizontal frames, and the bolts and knob nuts for fixing the horizontal frame to the vertical frame.
