Definitions

  • the invention relates to a pear and multi-button with at least one function button arranged on a button housing and one from an outlet opening of the connecting line leading out of the button housing.
  • Buttons of this type are known (cf. DIN 41050 Part 1, terms relating to nurse call technology). They are mostly used in the medical and nursing sector, where they allow a bedridden patient, e.g. from the bed to call the nursing staff. In order to have the button clearly visible in the patient's grip area, the button is usually operated using a holding element attached to its housing, e.g. hung from a hook or loop above the bed. However, such a holding element is generally not adjustable in length, so that the push button is often knotted with its connecting cable to a handle hanging above the bed as an erection aid.
  • the object of the invention is therefore to provide a button that can be hung length-adjustable on its connecting cable.
  • the push button housing is provided with a clamping bracket for receiving a portion of the connecting line to a loop extending from the outlet opening to the bracket.
  • a loop can thus be formed from the connecting line, which e.g. is guided around the handle of a hospital bed to the push button housing and is clamped there in the clamping bracket, so that the push button hangs on the handle by means of the loop.
  • the design of a button according to the invention allows a continuously adjustable hanging of the button with the connecting line without an additional device for hanging, such as. a hook is needed.
  • the clamp bracket is designed such that it releases the connecting cable when it is pulled.
  • the button can thus be suspended by means of a loop formed by inserting a section of the connecting line into the clamp holder of the button housing without the risk that the connecting line loop slips out of the holder.
  • the clamp holder of the recess releases the connecting line, which prevents damage to the connecting line due to excessive tensile stress.
  • the clamping bracket is sunk in an outer surface of the push button housing.
  • the clamp holder is a groove-like depression which is introduced into the surface of the push button housing, the cross section of the depression substantially corresponding in shape and size to the cross section of the connecting line, so that it can be inserted into the recess comfortably, but without play.
  • the depression also has a holding device which holds the connecting line inserted in sections in the depression in the depression and releases it when the connection line is pulled.
  • the groove-like recess has a U-shape, the ends of the legs of the U-shape adjoining an end face of the push button housing, in particular the end face provided with the outlet opening of the connecting line.
  • molded lugs are provided as a holding device on the recess.
  • a holding clip is arranged as a holding device, in particular in the region of curvature of the U-shaped recess.
  • the housing of the button has a substantially flat, elongated rectangular shape, with at least one of the corners being ergonomically rounded for ergonomic handling of the button.
  • the corner is rounded, which comes to rest when the button is handled with one hand in the palm of the operator's hand when function buttons arranged on the top of the button housing are actuated with the thumb.
  • the rounding off of the push button housing has a substantially circular arc-shaped recess from the top of the housing to the underside, in which a call button is arranged.
  • an advantageous embodiment provides that the call button arranged in the recess of the rounded corner can be actuated in the non-radial direction to the recess.
  • This is the Call button, which comes to rest on the palm of the operator's hand when the function keys located on the top of the button housing are operated with one hand, is protected against unintentional actuation by pressing with the palm of the hand.
  • the button In order to be able to operate the call button comfortably with one hand, the button must be pivoted around its front edge in such a way that the call button comes to rest on the thumb of the operator's hand, away from the ball of the thumb.
  • a button (1) according to the invention is described below with reference to FIGS. 1 and 2.
  • the button (1) comprises a button housing (2) with a connecting line (3) opening into the housing (2).
  • the button housing (2) has a flat, elongated, essentially rectangular shape and is about the size of a palm.
  • Function keys (61, 62) are arranged on an upper side (21) of the push button housing (2), with the aid of which room lighting (function key 61) and reading light (function key 62) can be switched on and off.
  • the corner (8) of the push button housing (2) located at the bottom right in the illustration in FIG. 1 is greatly rounded. If the button (1) is gripped in the position shown with the right hand in order to press one of the function buttons (61, 62) with its thumb, the ergonomically advantageous rounding (8) comes to rest in the ball of the hand, so that the rounding off (8) the handiness of the button (1) is improved.
  • an approximately thumbnail-sized, substantially circular arc-shaped recess (23) is formed, which passes through to the underside (22) of the push button housing (2).
  • a call button (5) is arranged in this recess (23).
  • the outer edge of the call button (5) continues the contour of the rounding (8).
  • the call button (5) is pressed by non-radial, for example in the sense of Arrow (P1).
  • the button (1) In order to be able to operate the call button (5) comfortably with one hand, preferably the right hand, the button (1) must be moved from the position shown in FIG. 1 to the position shown in FIG. 2.
  • the push button housing (2) pivoting around its end face (27). In the position shown in FIG. 2, the push button housing (2) can then be comfortably gripped with the right hand, with the thumb pressing the call button (5). Also in this grip position, the rounding (8) of the housing (2) has an ergonomically advantageous effect, since it essentially corresponds to the curvature of the relaxed thumb.
  • the call button (5) is then actuated in the direction of the arrow (P1) by moving the thumb inwards.
  • P1 In order to be able to find the call button (5) easily even in the dark, it is designed to be permanently glowing or fluorescent. As soon as it has been operated successfully, it lights up brightly to confirm the call.
  • Fig. 4 illustrates the arrangement and design of the recess (23) and the call button (5) arranged therein in a transverse side view according to the arrow (IV) of Fig. 2.
  • the continuous recess (23) extends from the top (21) to Bottom (22) of the push button housing (2).
  • the call button (5) has essentially the shape of a disc with rounded edges. It is visible both from the top (21), the bottom (22) and the short transverse side (28).
  • the connecting line (3) opens at the end face (21) through the opening (29) into the push button housing (2) (cf. FIG. 2).
  • the button housing (2) has an essentially U-shaped recess (24) on its underside (22).
  • the cross-section of the recess (24) is shaped such that the connecting line (3) can be inserted in sections in it. It is arranged in such a way that the legs of its U-shape are perpendicular to the end face (27) of the push button housing (2).
  • the connecting cable (3) e.g. a loop (30) is formed around the handle of a hospital bed, which is closed by inserting the connecting line (3) into the recess (24).
  • the recess (24) has outlet openings (26) with a widened cross section and retaining lugs (25).
  • the connecting line (3) can accordingly be inserted through the openings (26) into the recess (24), where it is held by the protruding retaining lugs (25).
  • FIG. 3 A view of the end face (27) of the push button housing (2) according to the arrow (III) is shown in FIG. 3.
  • the recess (24) on the underside (22) of the push button housing (2) borders with its cross-sectional openings (26) on the end face (27).
  • flush retaining lugs (25) are formed at the outer end of the openings (26) with the underside (22) of the housing (2).
  • the distance between a holding nose tip protruding into the opening (26) and the opposite edge of the widened opening (26) is so large that the cross section of the connecting line (3) can be carried out.
  • the depth of the recess (24) is selected so that the completely inserted connecting line slides with its cross section under the retaining lugs (25), and is thus held by the latter in the recess (24).
  • the underside of the retaining lugs (25) acting on the connecting line (3) is rounded, so that when the connecting line (3) is pulled, it can slide obliquely upwards along the underside of the retaining lugs (25) and is easily released. This can be supported by the fact that the walls of the recess (24) are slightly beveled towards the inside of the U-shape.
  • FIG. 5 shows a section of the bottom of the button housing (22) according to the section (V) of FIG. 2 in an enlarged view.
  • the depression in FIG. 5 has a retaining clip (7) which covers and clamps the connecting line (3) inserted into the depression (24) in the region of the curvature of the U-shape.
  • the retaining clip (7) consists of two clamping surfaces, of which the clamping surface (7a) lying on the underside (22) of the push button housing (2) is shown in the illustration in FIG. 5, and an elastic element connecting these two clamping surfaces, e.g. a coil spring.
  • the retaining clip (7) is so integrated in the push button housing (2) that the outer clamping surface (7a) is flush with the surface of the housing underside (22) and the other, not shown clamping surface parallel to the first clamping surface (7a) on the The interior of the housing facing deep end of the recess (24).
  • the two clamping surfaces advantageously protrude with clamping elements, e.g. Clamping lugs into the cross section of the recess (24).
  • the connecting line (3) If the connecting line (3) is pushed into the recess (24), it meets the clamping lugs of the clamping surfaces, as a result of which the clamping surfaces are pressed apart. Due to the pre-tension exerted by the elastic element Clamping lugs of the retaining clip (7) connect the connecting line in the U-shaped area of curvature and clamp it.
  • the bias of the elastic element is selected so that the connecting line (3) is held on the one hand in the recess (24), but on the other hand is easily released by the retaining clip (7) when the cable acting on the connecting line.
  • the recess (24) in the push button housing (2) and the holding device holding the connecting line (3) can of course also be designed in such a way that the connecting line is not completely released when the train acts and slips out of the recess (24), but rather with less Friction can be pulled through the recess (24) in the longitudinal direction. Pulling on the button or on the connecting line of the button thus yields and lengthens the loop without the connecting line being subjected to wear and tear.
