BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a block suspender, and more particularly, to a plurality of pantograph mechanisms composed of a sandwiching rod, which are pivotally supported by a main body beam, and the pivoting position of the sandwiching rod is an article (block or the like). The present invention relates to a block suspender that securely holds a large number of blocks at once by automatically changing the size according to the size of the block.

[0002]

2. Description of the Related Art Conventionally, as a block suspension of this type, two members are pivotally supported at a fulcrum and intersect to form an X-shaped holding member by utilizing the principle of leverage, An inverted V-shaped arm is connected from the end of the upper holding member to form a rhombus pantograph shape, and the intersection of the upper end of the inverted V-shaped arm and the shaft fulcrum are connected by a vertical sliding member, or There is a structure in which the ends of the inverted V-shaped arms are connected by a horizontal axis rod. Then, when the vertical sliding member contracts or the horizontal axis rod extends, the diamond-shaped pantograph is folded, the article holding portion on the tip side of the holding member opens, and the article is hung on the article to be lifted as it is, When the intersection of the inverted V-shaped arms is lifted, the diamond-shaped pantograph extends vertically from the folded state to close the article holding section, and the article holding section holds and lifts an article such as a block.

Further, as a block suspender for gripping a plurality of blocks, a sandwiching member formed in an X-shape by axially supporting two members so as to intersect each other at a fulcrum, and an opposite side from the end of the sandwiching member above the shaft fulcrum. It is known that a plurality of V-shaped arms are connected to each other to form a diamond-shaped pantograph shape and are hung on the main horizontal axis. Further, a pair of diamond-shaped pantograph-shaped members are positioned with a space therebetween, and the cross shafts and the shaft fulcrums are connected by a supporting horizontal shaft and a connecting horizontal shaft, respectively, and an article at the lower end of the sandwiching member. There is known a block suspender including a sandwiching horizontal bar having a sandwiching portion provided in parallel with a horizontal axis.

[0004]

However, in the former one of the above-described block suspenders for sandwiching a plurality of articles, each article sandwiching section is completely separate, and a plurality of article sandwiching sections can be provided at one time. Since it is possible to hang the articles, each article holding section operates separately, so it is troublesome and time-consuming to hold each article one by one.

Further, in the latter case, in the case of the block suspending device in which the article holding portion is constituted by the holding horizontal rods provided in parallel to the horizontal axis, the article holding portions are formed in one piece, and thus the article holding portions are separated one by one like the former. Although it is not necessary to grip, if there is a dimensional difference between the sandwiched articles, a small object may come off and slip off, and a large object may be damaged due to a large force.

In view of the above problems, the present inventor has studied various block hangings, formed a shaft hole into which a fulcrum shaft of a holding member is fitted, and changed the shaft fulcrum depending on the position of the hole. By making it possible, it has been clarified that the article clamping interval at the tips of the pair of article clamping members is changed for each pair, and the article can be reliably clamped with a uniform force.

The present invention has been made in view of the above-mentioned problems, and its object is to provide a block hanger which can hold a plurality of articles without damaging a plurality of articles with a device having a simple structure. To provide.

[0008]

A block suspending device of the present invention as a means for achieving the above object is an X-shaped member which is rotatably supported at one end of a pair of supporting shaft members by a fulcrum shaft at a central portion. One end of each sandwiching rod that is overlapped in shape is pivotally supported, and the other end is connected in an inverted V shape to form a diamond-shaped pantograph shape with the support shaft member and the sandwiching rod, and the lower end of the X-shaped sandwiching rod. A sliding member that pivotally supports a plurality of pantograph mechanisms each having an article holding member as a member on a main body beam, fixes a hollow shaft orthogonal to the main body beam, and vertically moves in the shaft in the axial direction of the shaft. A block hanging device that is fitted and inserted, in which a horizontal shaft member is fixed to the sliding member, a fulcrum shaft hole for fitting a shaft to the holding rod is formed in an elongated hole, and An abutting member is provided on the lower side, and the article is clamped or released by the article clamping member. When lowering the body beams when,
The lower contact member of the holding rod contacts the upper surface of the article, the horizontal shaft member reaches the upper surface of the article to insert the sliding member into the shaft, and the horizontal shaft member is attached to the holding rod near the fulcrum axis. Abut on each other to change the positions of the fulcrum shaft hole and the fulcrum shaft to adjust the distance between the article holding members.

According to a second aspect of the present invention, the block suspension has a plurality of hollow shafts fixed to the main beam.
The horizontal shaft member is fixed to the sliding member fitted into each shaft.

Is fixed and an article holding member is provided on the lower end member,
The contact member is provided below the branch member. Further, the block hanger of claim 4 of the present invention is
The contact member provided on the lower side of the branch member is provided so that its downward length can be adjusted.

In the block suspending device of the present invention, when the pantograph is contracted in the vertical direction, that is, when the space between the article holding members is widened and the beam main body is moved above the article and lowered, the lower side of the holding rod is held. The abutting member located at the first contact the large article first, and then the horizontal axis member reaches the upper surface of the article and stops. When the beam body is further lowered, the shaft is lowered and the lock mechanism provided on the sliding member is released, and the weight of the pantograph mechanism is applied to the abutting member and the horizontal shaft member, and the rhombus is crushed and the position of the fulcrum shaft with respect to the holding rod is lowered. Moves upwards. At this time, in a small article, the lozenge is crushed and the movement of the position of the fulcrum shaft with respect to the holding rod is small or does not move. In this way, the position of the shaft fulcrum is adjusted according to the size of the article.

Next, when the beam main body is raised, since the lock mechanism is released, the pantograph shape extends in the vertical direction, and the article holding member grips the article. At this time, in the pantograph mechanism in which the fulcrum shaft of the holding rod is moved to the upper position, the distance between the article holding members is increased according to the amount of movement, so that the dimensional variation of the articles is absorbed. Can be pinched. As a result, the force for pinching the article becomes uniform.

[0013]

As is apparent from the above description, according to the block suspending device of the first aspect of the present invention, the pantograph mechanism is contracted in the vertical direction, that is, the interval between the article holding members is widened and the main body beam is expanded. If the size of the object to be clamped is large or small, the contacting member of the clamping rod changes the position at which the contact member of the clamping rod abuts the article, and the amount of movement of the fulcrum shaft of the clamping rod changes accordingly. When the main body beam is raised to extend the pantograph mechanism in the vertical direction and the article is held by the article holding member, the fulcrum shaft of the holding rod moves substantially corresponding to the size of the article, and the distance between the article holding members is increased. Since the item is gripped according to the size of the item, it can be gripped at the same point in time even if the size of the item is large or small, and it is possible to prevent uneven gripping force. Do not damage it Succoth has the effect that it is.

According to the block suspending device of the second aspect, in addition to the effect of the first aspect, the operation of a large number of article holding members can be stably performed, so that the device can be made simple and compact. It has the effect that

According to the block suspending device of the third aspect, the branching member is branched by the branching member parallel to the main body beam, and the lower end of the holding rod is fixed to at least both ends of the branching member, and the abutting member is provided. Is provided below the branching member, the contact member of the pantograph mechanism is stable without tilting even when it comes into contact with an article, and the object can be smoothly attached and detached. Further, the abutting member hits a large article early, and hits a small article late, so that the fulcrum shaft can be easily adjusted.

According to the block suspending device of the fourth aspect, since the downward length of the contact member provided on the lower side of the branch member is adjustable, the contact position is changed. It can be applied to a wide range of items,
This has the effect of expanding the range of application of the block hanger.
