Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lateral beam erection device for mounting a lateral beam between two supports so as to be adjustable in height.

[0002]

2. Description of the Related Art Conventionally, various means have been used as this kind of apparatus. As the simplest method, there is a case where a number of insertion holes for hanging the cross beam between the two columns and a large number of locking projections for receiving the cross beam are provided stepwise.

[0003] However, in this case, a stable mounting state of the horizontal rail cannot be obtained, and in the case of the hooking protruding pieces, a large number of rows thereof are unsightly and the cost of the product increases.

In view of this, a number of vertical grooves are provided on both struts so as to detachably attach the horizontal brackets so that the horizontal rails can be supported by the vertical hanging hooks of any height. Sometimes it is done.

[0005]

Among the above, in the case of using a latch, if a horizontal rail is inserted from the end and hung therefrom, the distance between the two columns is reduced due to the insertion operation into both. On the other hand, since the length of the horizontal rail becomes extremely short, even if it is fixed with a pushing screw, the fixing becomes unstable, so that desired stability cannot be obtained.

[0006] Further, if notches are provided at both ends of the horizontal rail so as to be inserted into the latches from above, the horizontal rail can be erected even if the length is the same as the interval between the two columns. The crosspiece loses strength due to the notched groove.

[0007] In this regard, if joints of reinforcing members are connected to both ends of the horizontal rail and cutout grooves are provided in the horizontal rail, loss of strength of the horizontal rail can be avoided, but the cutout grooves are the same for both joints. It is necessary to connect so as to match the direction, and especially when the crosspiece has a cylindrical shape, the work and the correction are not easy.

In the present invention, in consideration of the above-described situation, a predetermined strength is maintained in the horizontal rail because a notch groove is provided in the joint of the reinforcing member to be fitted to the end of the horizontal rail so as to be hooked on the latch. And since the direction of the notch groove can be adjusted in the same way for the joints at both ends, the work of inserting into the latch is easy, and the horizontal beam can be strongly fixed even if there is a certain amount of space between the two columns. It is an object of the present invention to provide a device for erection of a horizontal beam between both columns.

[0009]

In order to achieve the above-mentioned object, the present invention provides a method in which longitudinal grooves are provided in a row in a stepwise manner on opposite surfaces of both columns, and a latch metal fitting on the longitudinal grooves is vertically arranged. Formed in a plate shape to be held, while forming a joint of a reinforcing member connected to both ends of the horizontal rail into a tubular shape so as to be an extension of the horizontal rail,
The peripheral wall is provided with a notch groove to be inserted from above into the latch, a groove on which the upper end of the latch is hooked, and a screw hole for the pushing screw, and the base end of the joint is pushed into the end of the horizontal bar. A connecting block to be fixed is protruded, and it is rotatably supported around the center of the joint as an axis, and a plurality of engaging portions where the tip of a screw pushing on the side surface of the latch is hooked are arranged side by side, and both columns are provided. This constitutes a device for erection of the horizontal rail between the two.

[0010]

[Function] Even if a joint is connected to both ends of the horizontal rail, the joint can be rotated with respect to the horizontal rail. Therefore, when the horizontal rail is installed between both columns, the joint is turned so that the cutout groove faces downward. It can be inserted into a latch. With this, the joint is engaged with the latch with the notch groove and groove at the center of the width and is held in a predetermined position, so when tightening the pushing screw, the joint is fixed to the latch with the correct combination, In addition, since the tip of the pushing screw is hooked on one of the engaging portions of the latch, a firm mounting state without lateral displacement is obtained.

[0011]

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 to FIG. 5 show an embodiment of a product display shelf. The product display shelf has a constant spacing between both columns 1, 1 as shown in FIG. 2 and FIG. One or a plurality of horizontal rails 3 are erected on the held frame-shaped shelf main body S, and the erection device is fitted with a hook 5 for hanging on the column 1 and an end of the horizontal rail 3. A joint 7 of the reinforcing member to be attached and a pushing screw 8 for fixing the joint 7 to the latch 5 are used (FIG. 1).

A circular pipe is used for each of the column 1 and the cross bar 3, and a number of vertical grooves 9 having different heights are formed in the column 1 at equal intervals inside the column 1 facing the other column 1.

However, the column 1 may be a square pipe. Further, when the material is a relatively weak material such as aluminum, as shown in FIG. 6, a concave groove 11 is provided in the column 1 and a vertical groove 9 is provided in a reinforcing member 13 incorporated in the concave groove 11.

The latch is a substantially rectangular plate, and is attached to the column 1 vertically and horizontally. A hook 15 is hooked on the vertical groove 9 at the front end for mounting, and the hook 15 is formed to be long at the top and short at the bottom, so that the lower end is hooked by inserting the upper end into the vertical groove 9 first. As shown in FIG. 5, a firm attachment state is obtained in which the camera never leans or bends downward.

A pair of left and right main engaging portions 1 on which the tips of the pushing screws 8 are hooked are provided on both side surfaces of the intermediate portion of the height of the latch 5.
7, 17 and a large number of sub-engaging portions 19 are provided between them. The main engaging portion 17 is formed by forming a round hole having a smaller diameter than the screw 8 to be pressed, and the sub-engaging portion 19 is formed by notches on both sides. The pressing screw 8 is engaged with one of the engaging portions 17 and 19 in accordance with the interval between the two columns 1 and 1. FIG.
Indicates a case where the hooking has been applied to the main engaging portion 17.

The joint 7 is a cylindrical member whose base end is closed, and is made of a strong metal and has a thick wall with an outer diameter substantially equal to that of the horizontal rail 3 as a reinforcing member extending from the horizontal rail 3. A shaft 23 is rotatably protruded from the center of the base end wall 21, and the connecting block 2 is fitted to the center shaft 23 at the end of the cross bar 3.
5 is fixed and rotatable.

The joint 7 is formed at one end of the peripheral wall with a notch groove 27 to be inserted into the latch 5 from the distal end to the proximal end, and the opposite inner peripheral surface is latched by a pair of protrusions. Grooves 29 on which the metal fittings 5 are engaged are provided to face each other, and thick portions 31, 31 are formed by protrusions on both sides located in the middle between the cutout groove 27 and the groove 29. Screw holes 33, 33 into which the screws 8 to be pushed into 31 are screwed are provided.

The connecting block 25 is adapted to be tightly fitted to and fixed to the horizontal rail at the base end. The connecting block 25 is easy to insert and has a slightly smaller distal end, and a middle portion formed in a neck-like shape with a particularly small diameter. You. In addition, the base end is formed with a rough surface in order to strengthen the connection with the horizontal rail.

Therefore, when the joint 7 is attached, the connecting block 25 is fixed to the cross rail 3, but since the joint 7 can rotate coaxially, the notch grooves 27, 27 are formed in both joints 7, 7. They can be matched in the same direction. FIG. 2 shows a case where the directions of the notch grooves 27 are different.

[0021]

[Effects of the Invention] As described above, according to the present invention,
A joint connected to both ends of the horizontal rail is formed in a cylindrical shape so as to extend the horizontal rail, and a notch groove which is inserted into the latch on the peripheral wall from above and the upper end of the inserted latch is formed. Since the hanging groove is formed, unlike the case where the notch is provided in the horizontal rail, not only the predetermined strength is maintained in the horizontal rail, but also the combination of the joint with the latch is accurate, and Even if the distance between the two columns is somewhat different, the cross beam can be stably installed and fixed firmly in place by tightening the pushing screw on the engaging part of the latch, so the load resistance of the cross beam Extremely large.

A connecting block is provided at the base end of the joint so as to be pushed into and fixed to the end of the horizontal rail, and is rotatably supported around the center of the joint. Irrespective of the orientation of the notch groove in the case, the joint can be reliably hung on the latch, so that there is an excellent effect that the workability of erection of the horizontal rail becomes very good.
