Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a horizontal cursor that can slide on a horizontal rail, a vertical rail attached to a wrinkled cursor, and a horizontal cursor that can slide on the vertical rail.
Vertical cursor for installing the trafting head,
The present invention also relates to a slide-type drawing machine that is constructed with a brake for the horizontal cursor, which is operated by an operating mechanism attached to the vertical cursor via a transmission mechanism.

Such a sliding drawing machine is well known from DE-PS 2507446, in which the transmission mechanism is guided by a brake lever of the brake and a roller attached to the lower end of the vertical rail, one end of which is connected to the vertical cursor. A wire is used, the other end of which is fixed to the actuating lever. When the actuating lever is in the first position, the wire is under a certain initial tension against the spring of the brake lever and is in a free state where no braking is applied. When the actuating lever is in the second position, the wire is pulled strongly past the first dead center, and the tension in the wire increases, causing the actuating lever to move toward the limit I.
Move to the device. In such a brake mechanism, a relatively large force is applied to the transmission mechanism and the operating lever not only in the free state but also in the braking state, which constantly places a load on the wire guide roller, and the operating mechanism is heavy and difficult to move. This is particularly disadvantageous in that the user requires a large amount of force to activate the operating mechanism (r-1) both in the free state and in the controlled state. A relatively large rotational moment must be applied to the actuating lever, and ':
The cursor suddenly says "J" and the settings may not be as you wish.

An object of the present invention is to provide a sliding drafting machine as described above, in which the brake can be reliably activated to lock and unlock the operating mechanism, and the lateral brake can be braked or released. The aim is to improve the vertical cursor so that it is light and can be used for UJ without any force being applied to the cursor.

This problem is solved by the present invention, in which the operating mechanism of the sliding drawing machine as described in the introduction changes the brake from a free state in which no braking is applied to a releasably locked braking state via a transmission mechanism. Along with operating the
The problem is solved by ensuring that no force is applied to the operating mechanism or the transmission mechanism whether the brake is in the free state or in the controlled state.

A particular advantage of the present invention is that the brake is releasably locked in the braking state, so that no load is placed on the transmission mechanism or the operating mechanism, while the brake operates reliably without loosening; Even in this state, no load is applied to the transmission mechanism and operating mechanism. Therefore, since no force is applied between the operating mechanism and the transmission mechanism, the operating mechanism attached to the vertical cursor is moved lightly along the direction of the transmission mechanism, not only in the controlled MJ state but also in the free state. Can be slid. Furthermore, the operation mechanism can be moved from a free state with no load, that is, without receiving an initial load from the brake mechanism.
It is possible to set it to a braking state. Similarly, there is no need to apply a force that overcomes the load imposed by the brake mechanism to bring the brake into or out of the braking state. It is desirable to apply a force to the operating mechanism or the swinging lever of the brake with a spring so as to give the operating mechanism a good relationship between displacement and force, which is independent of the load on the brake mechanism. It's about adding.

The transmission mechanism consists of a brake plate that extends along the entire length of the vertical rail and is rotatably supported around its longitudinal axis.Q)
It is advantageous to construct it as a rod, which acts on the swing lever or brake lever of the brake. By activating the operating mechanism, the stopper releasably locks the swinging lever via the rod, and as a result, the swinging lever is moved to the braking state where no load is applied to the rod or the operating mechanism. make it turn Next, when releasing the brake, the stopper is removed via the rod by the operating mechanism, and the appropriate restoring force is used to release the stopper.
(i'1!1iII lever and rod and 4e work (some parts are returned to the free state).

Preferably, the rod is made of a pinion shaft or a splined shaft with teeth parallel to the shaft. The swinging rhenoco has a rotating shaft parallel to the pinion shaft, and a 1-seal wheel that meshes with the pinion shaft is attached to one end of the rotating shaft.

The operating mechanism is preferably formed as a push button that allows a slide rod meshing with the pinion shaft to slide in a direction perpendicular to the pinion shaft, and at the same time meshing with the pinion shaft to rotate it.

In the state of 71J-, no force acts between the swing lever, the pinion shaft, and the toothed slide rod. Therefore, the slide rod is easily slidable along the pinion axis. The vertical cursor does not experience much resistance due to sliding friction between the pinion shaft and the slide rod. In the braking state, the swinging lever is fixed by the stopper, and even in the braking state, no force is applied between the swinging lever, the pinion shaft, and the slide rod equipped with the teeth of the push button. It is easily possible to slide the cursor along the vertical rail.

Since the horizontal rail is mounted to the drawing board for rotation about its longitudinal axis, there is usually a rigid connection between the vertical rail and the horizontal cursor via a right angle frame.

In the present invention, the horizontal brake is connected to the transmission mechanism in such a way that the brake in the braking state remains applied even when the vertical rail is lifted from the drawing board.

In order to reduce the force that has to be transmitted through the rod when actuating the brake, the brake is constructed with a piston guided to slide axially inside the sleeve. The piston and sleeve have brake linings on opposite sides. The lateral rails are designed to form a partially narrowed long hole in which the brake piston is seated and the shaft of the piston extends through it to the sleeve above it. It is desirable to have all the grooves. The piston and the sleeve are connected via a toggle lever, and a rocking lever acts on this to bring the toggle lever into an extended state when controlling the piston. With the above structure, only a small amount of force is required to be applied to the swing lever in order to generate the necessary braking force.

The swing lever is pulled into the free position by a first spring. The gear that meshes with the vinyl shaft is mounted so that it can move relative to the swing lever, and in order to release the brake from the braking state, it moves toward the second spring to release the brake. It is moved slightly beyond f. On the other hand, the swing lever ld remains stopped at the %J position. The fan-shaped float moves in response to the rotational movement of the pinion shaft moved beyond the control 0J position, the stopper is unlocked, and the rocking lever becomes free again, and is moved to the free position by the first spring. will be returned to. The movement of rotating the pinion shaft and the sector gear that meshes with it beyond the braking state is achieved by pressing the push button used in the operating mechanism against the knee 1 and second springs into the m-free state. When pushed beyond the @J1\γ position, the swing lever, pinion shaft, and push button return to the free position after the control 1fl), allowing easy operation.

Embodiments of the invention will be explained below with reference to the accompanying drawings.

The sliding type drawing machine shown in FIG. 3 are guided so that they can ski. The vertical cursor 5 is connected to the scale 11a via the hinge 7.
, l 11) is connected via a bridge 9 to a mounting plate 8 on which it is viewed.

Vertical cursor 5 can be replaced with horizontal cursor 3'f if necessary.
f: An operation 117 mechanism 12-18 is incorporated which makes the brake operation of the horizontal cursor 3 of the fixed scroll bar 3-T function. An @2 push button 13 for operating a brake for fixing the vertical cursor 5 is provided above the operation 12-18. Double push button (12, 13
) is perpendicular to the drawing plane in order to avoid forces acting in the direction of movement of both cursors 3.5. Therefore, by operating these brakes once and for all, the cursor 35.5 is fixed at the preset position.

As is clear from Fig. 2.3, the vinyl shaft 24, which serves as a transmission shaft, is provided with teeth 26 parallel to the shaft within the space 4b of the vertical rail 4, and extends over the entire length of the vertical rail. It's growing. The pinion shaft 24 is rotatably supported about a longitudinal axis by a number of bearing membranes 28 attached at intervals. Flat on the shaft of pinion shaft 24
The tooth 26 protrudes from the hole 4d of the rail 4, and there is a slide rod 18 which passes through the side hole 4e of the rail 4 and has a shaft 19 at its free end that meshes with the pinion shaft and is parallel to the shaft. extends perpendicularly to the pinion shaft 24. The slide rod 18 is rotatably supported in parallel to the pinion shaft 24 at the lower part of the push button 12, and is attached to the push button 12.
It meshes with a pinion 16 which is rotated by a dimension rod 14. Push button 12. Toothed rod 14. pinion 1

It meshes with the Q-shaped wing teeth 32.

? l: 32 degrees to the right, the end 34 of the swinging lever 30 still rotates to the left, and at the same time the brake 36 shifts to the m+ state. At this time, the stoppers 46, 47 releasably restrain the swing lever 30, thereby removing the load on the vinyl shaft 24 and the operating percentage closing mechanisms 12-18.

The brake 36 has a piston 40, which is guided in a groove in the yellow rail 2 and is conveniently located in the sleeve 38, so that its shaft 39 can be slid in the direction of the axial force. Sleeve 31J, distance between rail and brake 36 (dl'l casing ti

The sleeve 38 and the piston 40 are engaged by a toggle lever 44, and when the position 6 shifts to the σ1 state 4, the swinging lever 30 extends this, and at this time, the rotational moment +-U applied to the pinion shaft 24, the ratio Although it is relatively small, it produces a relatively large braking force.

In particular, as shown in FIG. 4, the swing lever 30 is pulled by the spring 50 @1 even in the free state (3).

The weak type Erto 32 (which meshes with the pinion shaft 24) is attached to the R14 moving lever 30 by 7tI so that ΦIJ can be made.

The pushbutton 12 is also brought into the free state via the vinyl shaft 24.

As can be seen in particular from FIGS. 2 and 5, the stopper 46 has a stopper pin 47 which is rotatable and is adapted to act on the first weak gear 32 by means of a spring.

The stopper 46 is cut slightly back by 1° from the point t so that the release can be performed with six effects, and the step ensures that the stopper 46 is set at the controlled position. The step near the free position is the stopper pin 47 which always reaches the control position in the same rotation and direction.

As described in detail in the embodiment described in Section 1, the sliding drawing system according to the present invention includes a horizontal cursor that can slide on the yellow rail, a vertical cursor that is attached to the yellow cursor, and a vertical cursor that can slide on the yellow rail. The movable trafting head is moved at 11'! by the operating mechanism attached to the vertical cursor and the vertical cursor. Exalted,
Whether the horizontal cursor is in the braking state or in the free state, there is no constant load on the sliding parts due to the force of the brake machine 1:j7i, and the operating mechanism can be operated easily.
Furthermore, so that the vertical cart can be easily moved, the operating mechanism applies the brakes via a transmission mechanism from a free state in which no braking is applied to a braking state in which the brakes are locked so that they can be released. Even in the state of l1
Even in the 1171+1& condition, the operating mechanism and the transmission mechanism are designed so that no load is applied to them, and therefore, the desired operation can be reliably expected with a simple configuration.
