Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for mounting and storing heavy objects (for example, various devices such as vises and measuring instruments) on a desk.

[Conventional technology]

Taking as an example the case of a vise that is used in factories, school workshops, etc. as a heavy object that is attached or placed on the top of a desk, a vise has traditionally been used to attach or place a heavy object on the top of a desk (workbench). It was firmly attached to the edge with bolts and nuts and could not be easily removed.

[Problem to be solved by the invention] Since the vise cannot be easily removed, the vise may get in the way when performing work on the top plate that does not require a vise, or it may become difficult to use other devices instead of the vise. The desk could not be used for any other purpose because various devices were placed on the top board. Furthermore, even if the vise were removed from the top plate, it would be very difficult to move the heavy vise, and a separate place would be required to store it, and the desk would actually be used as a workbench exclusively for the vise. The current situation is that As mentioned above, conventionally, no device has been provided for easily and quickly storing various heavy objects on the top of a desk when they are not in use.
This limited the scope of use of the desk and caused problems such as a lack of versatility.

[Means for solving problems]

As shown in FIG. 1, the device for attaching and storing heavy objects to a desk according to the present invention has a lower end 2a pivotably supported at a lower position of an end edge 4a of a top plate 4 so as to be able to swing back and forth, and an upper end 2a of the top plate 4. Gas spring 1 that urges the
A supporting column 1 has telescopic inner and outer cylinders 3 and 2 containing a support column 1, and a top plate 4, which fixes a heavy object W to be attached.
a heavy object mounting member 8 into which the end edge 4a of the support column 1 is fitted and removably fixed to the end edge 4a, and further pivoted to the upper end 3a of the support column 1 so as to be swingable in the front and rear directions; A second resilient member 17 that restricts the heavy object attachment member 8 from rapidly swinging forward; and a first resilient member 18 that restricts the support column 1 from rapidly swinging forward. , equipped.

[Effect]

The heavy object W attached to the heavy object attachment member 8 is
The support column 1 can be moved in a substantially horizontal U-shape by expanding and contracting and swinging, and by moving in this way, it can be taken out onto the top plate 4 and stored below the top plate 4. Each can be changed freely. That is, FIG. 1 shows a state in which the support column 1 is tilted forward and extended, and from this state, the heavy object W is pushed toward the opposite side (toward the top plate 4 side) and the support column 1 is swung as shown by arrow A. Heavy goods W
By fitting the heavy object attachment member 8 to the edge portion 4a of the top plate 4 while gradually raising it in the horizontal direction, the heavy object W can be taken out onto the top plate 4 as shown in FIG. Can be done. Also, from the state shown in Fig. 1, push the heavy object W diagonally downward as shown by arrow B to lower it to the state shown by the imaginary line, then push the heavy object W to the opposite side (below the desk 5) and move the support column 1 as shown by arrow C. By swinging it as shown in FIG. 3, the heavy object W can be stored under the desk 5 below the top plate 4. As shown in FIG. In addition, while the heavy object W is being moved, it is dangerous if the mounting member 8 swings around the pivot point with the support column 1 and the heavy object W suddenly tilts forward (towards this side). The swinging of the member 8 is regulated by the first resilient member 17. Furthermore, support column 1
A sudden swing forward (toward the near side) around the pivot point is restricted by the second resilient member 18. Therefore, the heavy objects W can be easily and quickly moved to and from the desk and under the desk, and can be freely changed between the take-out state and the storage state. And since the storage space uses the space under the desk, there is no need for any space other than the desk.
Moreover, desk space can be used effectively.

In the present invention, the term "front" refers to the near side, and the term "rear" refers to the opposite side.

〔Example〕

Hereinafter, one embodiment shown in the drawings will be described in detail.

In FIGS. 1, 2, and 3, the support column 1 is supported at the lower end 2a of the rectangular outer cylinder 2 at a position below the front edge 4a of the top plate 4, that is, at a position below and in front of the legs 6 of the desk 5. It is pivotally supported by a shaft 7 so as to be swingable in the front and rear directions, and a heavy object mounting member 8 is pivotally attached to the upper end portion 3a of the rectangular inner cylinder 3 by a shaft 9 so as to be swingable in the back and forth direction. The heavy object mounting member 8 is made of a flat plate, and one end thereof is bent into a U-shape to form a fitting recess 8a into which the front edge 4a of the top plate 4 is fitted. The mounting member 8 has two mounting pieces 1 on the left and right that protrude downward from the U-shaped portion.
0 and 10, and is connected to the inner cylinder 3 of the support column 1 by a shaft 9 between the mounting pieces 10 and 10. The support column 1 includes a gas spring 11 that spans the inner and outer cylinders 3 and 2, and the gas spring 11 supports the inner cylinder 3 by means of a slide shaft 13 that receives pressure from high-pressure nitrogen gas built into the pipe 12. It is constantly bombarded upwards. That is, the support column 1 is expandable and retractable by the inner and outer cylinders 3 and 2 and the gas spring 11. A heavy object to be attached (a vise is shown in the illustrated example) W is attached to the upper surface of the heavy object attachment member 8 . 14 is a bolt for mounting the vise W.

Reference numeral 15 denotes a round bar-shaped stopper which is horizontally fixed to the rear surface of the outer cylinder 2 in the form of left and right protrusions in order to restrict excessive swinging (tilting) toward the front (toward the near side) of the support column 1. comes into contact with the front leg 16 of the leg portion 6, thereby restricting further forward inclination of the support column 1.

A metal bar spring or a plate spring is used as the first elastic member 17 that relaxes and restricts the swinging of the heavy object mounting member 8 and the second elastic member 18 that relaxes and controls the swing of the support column 1. The elastic force caused by the bending is utilized. That is, one end (base end) of the first elastic member 17 is fixed 19 to the inside of the mounting piece 10 of the heavy object mounting member 8 so as to follow the side surface of the inner cylinder 3 of the support column 1.
The other end (tip) is inserted into the outer cylinder 2 as a free end. A pin 20 is implanted at a lower position on the side surface of the inner cylinder 3, with which the free end 17a of the resilient member 17 can come into contact when the mounting member 8 swings forward (toward the near side). Due to the contact, the resilient member 17 curves as shown in FIG. 1 to moderate and restrict rapid swinging of the mounting member 8 and the heavy object W.

In addition, one end (base end) of the second elastic member 18 is fixed 21 to the lower side surface of the outer cylinder 2 of the support column 1, and the other end (tip) is a free end that reaches the rear of the leg part 6, and , this free end 18a engages in a longitudinally elongated hole 23 of a stopper member 22 fixedly provided below the rear of the leg portion 6. As the support column 1 tilts forward, the second resilient member 18 has its free end 18a connected to the elongated hole 22 of the stopper member 22, as shown in FIG.
Since it is in contact with the upper locking portion 23a of the support column 1, it curves upward, thereby relaxing and restricting the rapid swinging of the support column 1. Furthermore, if the support column 1 tilts backward when storing a heavy object W, the free end 18
a comes into contact with the lower locking portion 23b of the elongated hole 23, and the second resilient member 18 curves downward, thereby relaxing and regulating the rapid swinging of the support column 1.

Therefore, the first and second resilient members 17, 1
8 serves to prevent danger to the human body due to the heavy object W and also to protect the heavy object W from impact.
The first resilient member 17 is configured to
It is determined whether to restrict the swinging of the mounting member 8 only in the forward direction or to restrict the forward and backward swinging thereof.

Reference numeral 24 indicates the attachment member 8 when the heavy object W is being taken out.
This is a locking device for fixing the device to the top plate 4, and its details are shown in FIG. That is, the locking device 24
A fastening rod 26 loosely inserted into the through hole 25 on the side of the mounting member 8, and a male threaded portion 2 at the tip of the fastening rod 26.
7 is made of a metal nut member 28 embedded in the top plate 4 to be screwed together. The fastening rod 26 has a stepped portion 29 between a base end 26a and a shaft portion 26b, and a handle 30 for rotational operation at the base end 26a. Further, the nut member 28 is formed by forming a female screw hole 31 in a square plate material, a round bar material, or the like. Reference numeral 32 denotes a metal reinforcing pipe buried in the top plate 4 concentrically with the female screw hole 31 of the nut member 28, with one end abutting the nut member 28 and the other end flush with the end surface of the top plate 4. The opening on the end surface side is a tapered portion 33. Numeral 34 is a nail driven in to prevent the nut member 28 from falling off when the top plate 4 is made of wood, and is particularly effective in preventing the nut member 28 from falling off when the top plate 4 is dry. Thus, the fastening rod 26 is inserted through the reinforcing pipe 32, the male threaded part 27 at the tip is screwed into the female threaded hole 31 of the nut member 28, and the mounting member 8 is pressed and fixed to the end surface of the top plate 4 by the stepped part 29. do.

According to this locking device 24, even if the top plate 4 is made of wood or the like and has a weak strength, the metal nut member 2
8 and the reinforcing pipe 32, it is possible to strongly tighten the fastening rod 26, and therefore the mounting member 8 and the heavy object W can be firmly fixed to the top plate 4. Moreover, attachment and detachment can be performed easily and quickly by rotating the handle 30.

In order to make it easier to move the heavy objects W for removal and storage, the inner cylinder 3 of the support column 1 or the heavy object mounting member 8 is attached to the fixed part of the desk 5 as shown by the imaginary line in FIG. It is also preferable to provide a guide rail 35 that guides the movement along an ideal trajectory by engaging a portion of the movement path. Further, if the heavy object W is an expensive item such as medical equipment, it is also preferable to attach a door 36 with a lock to the desk 5 as shown by the phantom line in FIG. In this case, it goes without saying that surrounding walls (not shown) may be attached to both sides and the back of the storage section.

Furthermore, the second resilient member 18 may be constructed of a wire 37 and a tension coil spring 38, as shown in FIG. 5, instead of a bar spring or a plate spring. That is, one end of the wire 37 is hooked near the upper end of the support column 1, the other end is hooked to a fixed part above the rear part of the desk 5, and one end of a tension coil spring 38 is fixed to approximately the middle part. At the same time, the coil spring 3
The other end of the wire 8 is hooked to the fixed portion of the desk 5 together with the wire 37. Therefore, when the heavy object W is taken out onto the top plate 4 (solid line state) and when it is stored below the top plate 4 (not shown), a part of the wire 37 (the coil spring 38 When the corresponding part) 37a is bent and the support column 1 is swung forward as shown in the imaginary line, the coil spring 38
A portion 37a thereof stretches out against the elastic force of , and the whole becomes straight. That is, the forward swinging of the support column 1 is moderated by the elastic force of the coil spring 38, and the forward swing position of the support column 1 is controlled by the wire 37.
and the coil spring 38 is regulated by the wire 3
The part 37a of 7 prevents elongation beyond the elastic limit.

In FIG. 5, the outer cylinder 2 and inner cylinder 3 of the support column 1 are installed in vertically opposite positions from those of the above-mentioned embodiment. Further, the first resilient member 17 may be omitted if the swing angle of the heavy object attachment member 8 with respect to the support column 1 is restricted to be small.

〔Effect of the invention〕

The heavy object mounting/storage device of the present invention moves the heavy object W in a substantially sideways U-shape by means of an extensible support column 1 that is swingable in the front-rear direction and has a built-in gas spring 11. Take out the top and top plate 4 downwards.
It can be stored freely, and the first springing member 17 and the second
Since the forward swinging of the heavy object mounting member 8 and the support column 1 is restricted by the resilient member 18, the heavy object W cannot be held with one hand, such as a vise, sewing machine, or medical equipment. To easily, safely and quickly store the heavy item W under the top plate 4 with one hand and take it out onto the top plate 4 when the item is heavy and would get in the way if left on the desk all the time. be able to. In addition, in the stored state, both the entire device and heavy objects W can be placed under the desk 5, so a door can be attached to the storage section and locked. Especially if the heavy objects W are expensive items such as medical equipment, etc. It is convenient in some cases. Furthermore, since the support column 1 crosses the top dead center while swinging between the forward tilted position in the pulled out state and the backward tilted position in the stored state, the movement of the heavy object W is smooth from this top dead center. I can do it. Furthermore, the moving speed of the heavy object W can be controlled by the gas spring 11, and there is no risk of sudden movement. This device can be used in a wide range of settings, from factories and school workplaces to hospitals, and has excellent versatility.
