DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame frame for supporting, which is arranged on a peripheral portion of an article such as a carpet or a rug laid in a room, for example.

[0002]

2. Description of the Related Art It has recently been proposed that the above-mentioned frame-shaped frame be placed on a floor or the like while sandwiching a peripheral portion of the above-mentioned article, and is formed of a soft material such as rubber or thermoplastic elastomer. Is thought to be. This frame-shaped frame can be integrally molded by injection molding, press molding, etc., but since it is bulky surrounding the article occupying a relatively large space, a large mold is manufactured for the integral molding. Must be done, which increases the manufacturing costs. In addition, it is expected that the integrally formed frame-shaped frame is troublesome in inventory, transportation, handling, and the like, and that high cost is inevitable.

[0003]

SUMMARY OF THE INVENTION In view of the above, it is an object of the present invention to solve the disadvantage of the frame-shaped frame for bulky integral molding which is difficult to handle at high cost. Each frame unit is divided into four sides to form a frame unit, and adjacent frame units are firmly connected to each other to enable assembling. When unnecessary, the frame units can be disassembled and removed for each frame unit for management. An object is to provide a picture frame.

[0004]

The present invention has the following arrangement as means for solving the above-mentioned problems. (1) A frame-shaped frame in which adjacent frame units made of a soft material are assembled by engaging their connection ends, and an engagement concave surface is formed on the connection end surface of one adjacent frame unit. A fitting protrusion protruding from the engagement concave surface is formed, an engagement portion formed of a hard material is formed at a connection end of the other frame unit, and the fitting protrusion is formed in the engagement portion. A frame-shaped frame fitted into the through hole and elastically deformed by a pressing member provided on the engaging portion, so that the engaging portion is engaged with the concave engaging surface. (2) The picture frame according to (1), wherein the pressing member is a pressing section integrally formed with the engaging section via the hinge section, and the pressing section is displaceably provided at the pressing position and the non-pressing position. Frame. (3) The frame-shaped frame according to (1), wherein the engagement portion is formed of a hard resin that can be thermally welded to the elastomer forming the frame unit, and is integrally formed at a connection end of the frame unit.

According to the present invention, a frame unit is constructed by assembling a frame unit which is not bulky at a required place, and has the following features. This is an engagement structure in which the frame units made of a soft material are not easily disengaged once they are assembled by the concave and convex fitting of the hard material and the soft material at the connection end. Since the soft fitting projection is pressed and elastically deformed after being inserted into the through hole, the engagement is strongly performed, and there is a possibility that the engagement may be disengaged even if the foot is stepped on or kicked or moved. Absent. Preferably, the pressing member for pressing the fitting convex portion can be integrally formed with the engaging portion via the hinge portion, and the number of components is small, and the pressing operation can be easily performed. Preferably, the engaging portion made of a hard resin can be integrally formed with the frame unit made of an elastomer by injection molding or the like, and no troublesome work is required for integrating the engaging portion and the frame unit. It is removable and when it is unnecessary, it is sufficient to disassemble the assembled frame and store the frame unit.

Embodiments of the present invention will be described below. FIG. 1 is a plan view of a substantially rectangular frame-shaped frame according to one embodiment of the present invention, FIG. 2 is a side view and a bottom view of a frame unit A constituting the frame-shaped frame, and FIG. It is a figure and a bottom view.

In FIG. 1, a frame-shaped frame 1 is arranged so as to surround a periphery thereof in order to support a substantially rectangular article S located at the center. The frame-shaped frame 1 is formed by connecting a pair of frame units A, A forming short sides facing each other in a substantially rectangular shape and a pair of frame units B, B forming long sides, respectively. It is assembled and formed.

The frame unit A shown in FIG. 2 has a main body 2 made of an elastomer such as a thermoplastic elastomer (olefin-based elastomer, styrene-based elastomer, urethane-based elastomer, etc.) or rubber.
Is concaved to form an engagement concave surface 4, and the engagement concave surface 4
A substantially L-shaped fitting projection 5 is integrally provided from a part of the body to a height substantially equal to that of the main body 2.

A frame unit B shown in FIG. 3 has a main body 7 formed of an elastomer, similarly to the frame unit A, and a connection end 8 of the frame unit B has a hard resin which can be thermally welded to the elastomer forming the main body 7, for example. It is integrally formed of an olefin resin such as polyethylene and polypropylene. The connecting end 8 includes an engaging portion 9 extending from the main body 7 in a substantially perpendicular direction so as to be fitted to the engaging concave surface 4, and the engaging portion 9 has a substantially L-shaped through hole 10. A substantially triangular pressing section 11 is formed along the through hole
Is formed integrally with the engaging portion 9 so as to be rotatable via the. Reference numeral 13 denotes an insertion protruding piece protruding from the tip of the engaging portion 9, which is inserted into the insertion hole 6 formed in the engaging concave surface 4 of the frame unit B to facilitate the engagement.

The frame unit A and the frame unit B are shown in FIG.
As shown in FIG. 6, the adjacent connecting ends 3 and 8 are overlapped with each other, the insertion projection 13 is inserted into the insertion hole 6, and the fitting projection 5 is fitted into the through hole 10. The engagement between the pressing section 11 and the side wall of the fitting convex portion 5 is achieved by rotating the pressing section 11 so that the pressing section 11 is elastically deformed. In addition, the press contact surface 14 between the pressing section 11 and the fitting convex portion 5 can be formed as a tapered surface so that a strong press contact can be made.

In the above-described embodiment, an example is shown in which the four sides constituting the frame are connected and engaged at the four corners using individual frame units. However, the present invention is not limited to this. However, the present invention also includes a frame-shaped frame formed by engaging the connection ends of at least two frame units. Further, the positions and shapes of the engaging concave surface 4, the fitting convex portion 5, the engaging portion 9, the through hole 10, the pressing piece 11, and the like can be appropriately changed within a range in which the object of the present invention is achieved.

[0012]

According to the present invention, even for a frame frame having a large volume, it is only necessary to fit a frame unit obtained by appropriately dividing the frame unit and to fit the frame unit. This significantly reduces costs and is advantageous in transportation, storage and handling. In addition, the fitting between the frame units is strong, and there is no possibility that they will come off during use.
