Description

[Detailed description of the invention] Industrial application field This invention relates to display devices for vinyl hoses, rubber hoses, electric wires, chains, ropes, etc. (collectively referred to as hoses, etc.).
More specifically, the present invention relates to a locking structure that can easily lock a heavy reel wrapped around a hose to an arm.

BACKGROUND ART AND PROBLEMS Conventionally, as shown in FIG. 5, this type of reel locking structure includes a holding frame 54 that holds a reel 53 on a horizontal crosspiece 52 provided across a plurality of supports 51. A device in which a locking portion 55 was locked was used.

However, in the case of this structure, in order to lock the holding frame 54 holding the reel 53 to the horizontal crosspiece 52, first hold the grip portion of the holding frame 54 and hold the heavy reel 53 with the hose wound thereon horizontally. It was necessary to carry out the troublesome work of lifting the reel 53 to the height of the crosspiece 52, holding the reel 53 in this state so that the holding frame 54 is horizontal, and then locking the locking part 55 to the horizontal crosspiece 52. Especially lifted reel 53
It took a great deal of effort to level the holding frame 54, and female workers in particular had a lot of trouble locking it.

In view of the above points, the object of this invention is to provide a reel locking structure that can easily lock a reel around which a hose or the like is wound to an arm.

Means for Solving Problems The reel locking structure according to this invention, as shown in the attached FIGS. 1 to 4, has arms 2 protruding forward from a plurality of columns 1 arranged at required intervals. , the upper surface 3 of each arm 2 is a sliding surface with an upward slope toward the front;
Engagement grooves 4 are provided in the width direction at required positions,
On the other hand, engagement protrusions 7 that protrude sideways are provided on both sides of the holding frame 6 that holds the reel 5, and the engagement protrusions 7 slide backward on the upper surface 3 to engage the engagement groove 4.
The holding frame 6 is locked to the arm 2 by being fitted into the holding frame 6.

In a preferred embodiment of this invention, a frame receiving member 18 is provided on the side surface of the arm 2 in the longitudinal direction, and the frame receiving member 18 receives the holding frame 6 when the engaging protrusion 7 and the engaging groove 3 are fitted. It's becoming like that.

In the case of the structure of this invention, in order to lock the holding frame 6 holding the reel 5 to the pair of left and right arms 2, first hold the grip part of the holding frame 6 and hold the reel 5 with the hose wrapped around it. lift. Next, the pair of left and right engagement protrusions 7 of the holding frame 6 are placed on the front ends of the left and right arms 2, respectively, and slid backward on the inclined upper surfaces 3 to fit into the engagement grooves 4.

Embodiment Next, an embodiment of this invention will be specifically described based on the drawings.

1 to 4, a support column 1 is provided with two arms 2, upper and lower, projecting forward by welding. The upper surfaces 3 of the upper and lower arms 2 are both sliding surfaces that have a gentle upward slope toward the front. Further, on the upper surface 3 of each arm 2, an engagement groove 4 is provided in the width direction slightly forward of the center of the length. Frame receiving members 18 are welded to both side surfaces of each arm 2 over the entire length. The upper surface of the member 18 is lower than the upper surface 3 of the arm 2, so that the frame receiving member 18 receives the holding frame 6 when the engaging protrusion 7 and the engaging groove 3 are fitted together, as will be described later.

A lower frame 8 is provided at the lower end of the column 1, and an upper frame 9 is provided at the upper end.
are each provided in a forward-projecting shape by welding. Note that the upper frame 9 may not be provided. An L-shaped bent piece 1 is attached to the rear surface of the upper end of the column 1.
0 is set.

A plurality of supports 1 including upper and lower arms 2 and upper and lower frames 9 and 8 are placed on the base 13 of the display device 12, and the hanging pieces 10 are hung on the horizontal beams 14 of the display device 12. There is. In this way, the plurality of support columns 1 arranged at regular intervals on the display device 12 are connected to each other by the angle members 11.

On the other hand, a U-shaped holding frame 6 that holds the reel 5
Engagement protrusions 7 that protrude outward are welded to both sides of the reel shaft 1 that protrude inwardly.
5 is welded. In addition, left and right reel spindles 1
A spherical portion 16 is welded to each tip of the cylindrical member 5 .

The reel 5 with the hose wound thereon is held by the holding frame 6 by fitting the left and right reel support shafts 15 of the holding frame 6 into the shaft holes 17 of the reel 5.
Since the reel support shaft 15 is provided with the spherical portion 16, even if this comes into contact with the side surface of the reel 15, it will not damage the same surface.

In order to lock the holding frame 6 holding the reel 5 to the pair of left and right arms 2, first, hold the grip portion of the holding frame 6 and lift the reel 5 with the hose wound thereon. Next, the pair of left and right engagement protrusions 7 of the holding frame 6 are placed on the front ends of the left and right arms 2, respectively, and slid backward on the inclined upper surfaces 3 to fit into the engagement grooves 4. At the same time as this fitting, the holding frame 6
Both sides of the frame are received by the frame receiving member 18. As a result, rotation of the holding frame 6 is prevented, and the holding frame 6 holding the reel 5 is locked to the pair of left and right arms 2 with good stability. After the locking operation, the price card is attached to the grip portion of the holding frame 6.

Effects of the invention Since the reel locking structure according to this invention is configured as described above, in order to lock the holding frame 6 holding the reel 5 to the pair of left and right arms 2, first grasp and hold the holding frame 6. and lift the reel 5 with the hose wrapped around it. Next, all that is required is to place the pair of left and right engagement protrusions 7 of the holding frame 6 on the front ends of the left and right arms 2, respectively, and slide them backward on the slanted upper surface 3 to fit them into the engagement grooves 4. .

Therefore, unlike the conventional reel locking structure described at the beginning of this document, the reel with the hose wrapped around it can be easily locked to the arm without requiring a lot of effort to lock the reel.
