Abstract

Zariadenie umožňuje pomocou nastavitel'- neý skrutnej pružiny odklopenie žehliacej došky do otvorenej polohy. Aretácia prítlačnej sily žehliacej došky v uzatvorenej polohe zaisťuje pákový mechanizmus s uzáverom, ktorého súčasťou je nastavitelný vačkový uzávěr. Pružný člen je vytvořený žehliacou poduškou. Podstata zariadenia spočívá v tom, že horný vyhrievací celok je pevne spojený s horným ramenom, ktoré je otočné spojené so spodným ramenom prostredníctvom čapu, na ktorý je nasunutá skrutná pružina, ktorej jeden koniec je zasunutý v hornom ramene kíbu a druhý v nastaviteTnom krúžku, ktorý je fixovaný v voči spodnému ramenu kolíkom, pričom v hornom ramene je na čapě umiestený držiak, v ktorom je uložený nastavitelný tvarový uzáver, do ktorého je samosvorne zasunutá kladka, ktorá je uchytená na kratšej straně dvojramennej páky, ktorá je otočné umiestená pomocou kíbu na hornom vyhrievacom celku.The device enables the ironing board to be tilted into the open position by means of an adjustable torsion spring. The locking of the pressing force of the ironing board in the closed position is ensured by a lever mechanism with a lock, which includes an adjustable cam lock. The elastic member is formed by an ironing cushion. The essence of the device is that the upper heating unit is firmly connected to the upper arm, which is rotatably connected to the lower arm by means of a pin onto which a torsion spring is inserted, one end of which is inserted in the upper arm of the joint and the other in an adjustable ring, which is fixed in relation to the lower arm by a pin, while in the upper arm there is a holder placed on the pin, in which an adjustable shaped closure is placed, into which a pulley is self-lockingly inserted, which is attached to the shorter side of the two-arm lever, which is rotatably placed by means of a joint on the upper heating unit.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for detaching and locking the upper heating element of an electric flat ironing machine, which is intended primarily for use by households. It consists of an upper and a lower part, with the upper hinged part forming a heated unit, the lower part being formed by a plastic plate with an ironing pad. The upper part is connected to the lower part by a joint system which includes a spring tensioning mechanism which ensures the upper heating element is removed from the laundry. The locking mechanism of the upper heating element pressure in the closed position is provided by a lever mechanism with a lock.

To date, the known device distinguishes, in particular, the position of the positioning of the joint of the upper heating element with a spurious portion. Apparatus having hinge joints placed in the transverse ironing dog use a spring biasing mechanism utilizing the biasing of the compression spring, wherein the movable element is rolling over the cam. This cam either. it forms a rigid part of the frame without being adjustable, or is part of a rotatable thrust plate, and is replaceable.

The solution to another group of ironing presses is such that the lower link joint arm is located in the right corner of the support, with the upper link arm connected to the upper heating element in its cross axis. The hinge pin is formed by a pipe in which a helical spring is placed to ensure that the thrust plate is tilted. In the region of the central part opposite the hinge, the ironing press is provided with a lever mechanism which ensures the upper heater assembly is tilted and at the same time ensures the pressing force is secured by the lock located in the central part of the upper heater assembly. The lever mechanism is located outside the upper heating unit. In addition to these irons, we are familiar with simple construction types, without pressure clamping, with a hinge connection in the right rear, comprising a screw or coil spring, ensuring that the upper heating element is swiveled.

The first of these systems has an ironing spacing provided by a central placement of the sponge which prevents the transverse displacement of the garment. The second type of ironing presses, whose design provides a transverse transition, has a problem with the draw-out of the locking system using only manual pressure.

The aforementioned drawbacks are eliminated by the device for detaching and locking the upper heating unit according to the invention, consisting of a hinge system which is provided with a helical spring with an adjustable element and a lever mechanism, the essence of which is that the upper heating element the whole is rigidly connected to the upper arm, which is pivotally connected to the lower arm by means of a pin, whereby a helical spring is inserted, one arm of which is inserted in the upper arm of the joint and the other in an adjustable ring, which is fixed to the lower arm of the joint, in the upper arm there is a drop-mounted holder, in which an adjustable shape closure is mounted, into which a pulley, which is clamped on the shorter side of the two-arm lever, which is rotatably mounted on the upper heating unit, is inserted.

The device according to the invention is of a simple design with a low installation and particularly easy operation, whereby a relatively low force can be used to lock the pressurized upper heating element in the closed position in the required cases. The placement and the solution make such that it ensures good ironing of the laundry when moving in both the rearward and the rearward directions. An exemplary embodiment is shown in the drawings, in which FIG. 1 shows a top view in a closed position with a section of a springy tilting and tensioning mechanism. FIG. 2 shows the device in the closed position by using the arresting force of the upper heating element. Fig. 3 shows the device in the open half.

The device consists of a swivel joint which secures the connection of the upper heating unit 1 to the lower support plate 2. It consists of an upper arm 3 and a lower arm 4. The tilting spring 5, one end of which is retracted, secures the upper heating unit. in the upper arm 3 and the other in the ring 6, which adjusts the required biasing of the helical spring 5. The position of the ring 6 is fixed to the lower arm 4 of the joint 7.

The connection of the upper arm 3 of the lower arm 4 itself is secured by a bolt 8 pressed into the lower arm 4. The bracket 9, which is connected to the pin 8 of the lower arm 4, is provided to limit the axial displacement of the upper arm 3. The closure device 10 is adjustable by means of a screw 11. The twin-arm lever 12 is part of the closure device. The cable 13 of the twin-arm 12 is located on a beam that crosses the ironing plate. The self-levering lever 12 has a sheave-mounted pulley 14 on the shorter end, the second longer part of the lever 12 terminates in the upper-sleeve shape 15. During the actual operation, the upper heating element 1 is moved to the open position in the spring biasing action 5 (FIG. ). Restraint position limitation cut off by upper arm stop 16.

Claims

5 or the base of the upper hinge 1 is moved by the bottom and the upper heater 1 is lowered downwardly. In the case of arresting the pressing force, the right-hand lever 12 is fixed and the shifting of the shifting lever turns the shorter side of the lever 12 around the hinge 13. As a result, the cam closure 10 is slidable, and thus the creep clutch 10 is inserted. Release of the upper heating element 1 is accomplished in the reverse order. By gripping the B double-arm lever 12 with the right hand and rotating it around the joint 13 by moving it upwardly to move the shorter side of the double-arm 12 downwards, resulting in the pulley 14 being moved out of the molded closure 10. By gripping the handle 16, which is connected to the upper heating element 11 'by upward movement and rotating the pivot 8, the upper heating element 1 is raised. In the position according to FIG. 3, the upper heating element 1 is fixed in an open semi-helical spring S. In this position he assembles an ironed object.
