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 that the invention seeks to solve]

Since the vise cannot be easily removed, the vise becomes a hindrance when performing work on the top plate that does not require a vise, or when other types of equipment are placed on the top plate in place of the vise. I was unable to use the desk for any other purpose. Furthermore, even if you remove the vise from the top plate, it is extremely difficult to move the heavy vise, and you will need a separate place to store it, and in reality, your desk will become like a workbench exclusively for the vise. The current situation is that As mentioned above, conventionally,
A device for easily and quickly storing various heavy objects on the desk top when not in use was not provided, which limited the range of use of the desk and resulted in 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 fitting recess 1a into which a heavy object W to be attached is attached and into which a top plate 2 and an edge 2a are fitted. and a heavy object attachment member 1 that is detachably fixed to the edge 2a; a link mechanism 10 that movably supports; and a resilient support member 11 that elastically biases the link mechanism 10 or a part of the heavy object mounting member 1 upward to elastically support the heavy object W. , and.

[Effect]

The heavy object W attached to the heavy object attachment member 1 is
While being supported by the resilient support member 11 (for example, a gas spring, etc.), the link mechanism 10 moves in a substantially horizontal U-shape as shown by arrow A in FIG. The storage state can be changed downward. That is, when the heavy object W is pulled toward the front from the unloaded state shown in FIG. 1, the heavy object mounting member 1 slides on the top plate 2 and the link mechanism 10 swings toward the front. The posture is as shown. From this state, by slightly pulling the heavy object W further toward you, the tip edge of the heavy object mounting member 1 is attached to the top plate 2.
from the edge 2a of the mounting member 1 and the heavy object W.
can be moved downward. By lowering the heavy object W to a position below the top plate 2 and then pushing it to the back of the desk 5, the link mechanism 10 swings rearward and the heavy object W is guided to the space below the desk 5, and the link mechanism 10 assumes a posture as shown by the solid line in FIG. 2, and supports the heavy object W in a stored state below the top plate 2 together with the spring support member 11. Note that the movement to the unloading state is performed in the reverse procedure to the above.

As described above, the heavy object W attached to the heavy object mounting member 1 is freely movable above the top plate 2 and below the top plate 2 in a substantially horizontal U-shape by the link mechanism 10, and the elastic support member 11, it can be easily and quickly changed between the take-out state and the stored state, and there is no sudden change in posture during the movement, so the movement can be carried out smoothly and safely. Furthermore, since the storage space uses the space under the desk, there is no need for 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 of the present invention will be described based on FIGS. 3 and 4.

The heavy object mounting member 1 is made of a flat plate material, and one end thereof is bent into a U-shape to form a fitting recess 1a into which an edge 2a of the top plate 2 is fitted. The upper surface of the mounting member 1 is equipped with a heavy object to be mounted (a vise is shown in the figure).
W is attached with a fixing member 3 such as a bolt, and two long and short connecting pieces 4a and 4b are fixed on the left and right sides of the lower surface of the U-shaped bent portion. This long-side connecting piece 4a is a swinging lever that is pivotally connected to a substantially central position in the lower front-rear direction of the leg part 6 of the desk 5 via two upper and lower dogleg-shaped links 8 and 9, so as to be able to swing back and forth. 7 and forms a parallel link mechanism 10 together with the links 8, 9 and the swing lever 7. The swinging lever 7 is configured as a left and right pair so as to approximately correspond to the two connecting pieces 4a and 4b, and the swinging lever 7 on one side connects the long side connecting piece 4a and the two upper and lower links 8,
9, and the swing lever 7 on the other side
is connected to the connecting piece 4b on the short side by the link 8,
On the other side, the lower link 9 is omitted. Further, the links 8 and 9 are bent downward and are interposed between the connecting pieces 4a and 4b and the swing levers 7 and 7, and the pair of swing levers 7 and 7 are connected by stays (not shown). are integrally connected.

Next, a gas spring 12 is used as the resilient support member 11, and the upper and lower ends of the gas spring 12 are connected between the long and short connecting pieces 4a and 4b, and between the desk 5.
It is pivotally connected to the front lower position of the leg part 6 by support shafts 13 and 14 so as to be able to swing back and forth, and the heavy object attachment member 1 is always elastically biased upward by the pressure of the high-pressure nitrogen gas contained therein. It plays the role of elastically supporting a heavy object (vise) W. In addition, the gas spring 12
The upper end of the connecting piece 4 forming the link mechanism 10
It may be directly connected to the heavy object attachment member 1 without being connected to a, 4b.

Thus, the parallel link mechanism 10 can swing back and forth as a whole around the lower end of the swing lever 7, and the connecting pieces 4a and 4b can move up and down while always remaining parallel to the swing lever 7. and can approach and separate freely. Therefore, the vice W, which is a heavy object attached to the mounting member 1, is connected to the parallel link mechanism 10.
Due to the action of , the parallel link mechanism 10 can be moved in a substantially horizontal U-shape as shown by the arrow A in FIG. This is the posture in the unloading state or the posture in the heavy object W storage state shown in FIG. Further, since the gas spring 12 supports the heavy object W, the heavy object W can be moved safely and smoothly. Furthermore, in order to make it easier to move this heavy object W for taking out and storing it, a third
As shown by the imaginary line in the figure, a guide rail 15 is attached to the fixed part of the desk 5 to engage a part of the link mechanism 10 or a part of the mounting member 1 and guide it to an ideal movement trajectory. preferable.

In the figure, reference numeral 16 denotes a stopper mechanism that regulates the amount of the heavy object W to be pulled out when it is pulled out and also determines the pushing position when it is pushed in, and is rotatably interposed between a pair of swinging levers 7, 7. A bar 17 having a rectangular cross section is pivotally connected to the rear part of the leg part 6 by a shaft 18 so as to be able to freely swing in the vertical direction. It consists of a stopper 19 and a regulating rod 21 having a push-side stopper 20. Furthermore, a compression coil spring 22 is interposed between the drawer-side stopper 19 and the bar 17 in the regulating rod 21 to absorb the shock when drawing out, while the bar 17 side of the push-in-side stopper 20 is provided with an elastic material such as rubber. A material 23 is attached to absorb shock during pushing.

24 is the attachment member 1 when the heavy object W is being taken out.
This is a locking device for fixing the device to the top plate 2, and its details are shown in FIG. That is, the locking device 24
A fastening rod 26 loosely inserted into a through hole 25 on the side of the mounting member 1, 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 2 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 2 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 2. 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 2 is made of wood, and is particularly effective in preventing the nut member 28 from falling off when the top plate 2 is dry. Thus, the fastening rod 26 is inserted through the reinforcing pipe 32, and the male screw portion 27 at the tip is screwed into the female screw hole 31 of the nut member 28, and the step portion 29 presses and fixes the mounting member 1 to the end surface of the top plate 2. do.

According to this locking device 24, even if the top plate 2 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 1 and the heavy object W can be firmly fixed to the top plate 2. Moreover, attachment and detachment can be performed easily and quickly by rotating the handle 30.

In the embodiment described above, the elastic support member 1
By using the gas spring 12 as 1, the gas spring 12 crosses the top dead center in the middle of swinging as the heavy object W moves between the pull-out position and the push-in storage position. This has the advantage of allowing smooth movement between the two. Furthermore, the moving speed of the heavy object W can be controlled, and there is no risk of sudden movement.

Further, as the resilient support member 11, in place of the gas spring 12, it is preferable to insert a coil spring or a plate spring in the direction of supporting the heavy object in response to a change in distance between each component of the link mechanism 10. Also,
For example, as shown in FIG. 6, the lower link 9 may be extended rearward and its tip may be resiliently biased by a tension coil spring 35.

Note that if the heavy object W is an expensive item such as a medical device, 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.

〔Effect of the invention〕

In the heavy object mounting and storage device of the present invention, the heavy object W is moved in a substantially sideways U-shape by the link mechanism 10 and is always resiliently supported by the resilient support member 11. In the case of items such as vises, sewing machines, and medical equipment that cannot be held with one hand and that would be a nuisance if left on the desk all the time, you can easily and safely carry heavy objects W with one hand. Moreover, it can be quickly stored under the top plate 2 and taken out onto the top plate 2. In addition, in the stored state, both the entire device and the heavy objects W can be placed under the desk 5, so it is possible to attach a door to the storage section and lock it. Useful for things. Moreover, it can be used in a wide range of places, from factories and school workplaces to hospitals, and has excellent versatility.
