Description

[Detailed Description of the Invention] Brother"ShiLa"L91- This invention is for connecting two parts that can mutually rotate around a rotation axis to an installation member, The invention relates to a coupling device in which each of the two parts to be connected has at least two half parts separated along a separation plane, and the axis of rotation lies near the separation plane of the two parts to be connected.

The object of the invention is to provide a coupling device which is simple in construction, easy to set up and inexpensive to manufacture, and which connects two parts assembled from several parts to each other.

According to the invention, the two parts to be joined each have a pin-like or sleeve-like attachment, and these attachments are arranged concentrically with respect to the axis of rotation, so that the installation members are radially aligned together. At least one part is held and the attachment of the other part to be connected can be fixed in the axial direction to the attachment of the one part.

These attachments can be fixed to each other directly or via separate elements. These attachments are concentric to the axis of rotation, so they are each separated into two parts, with a separating (or mating) surface.
is passing through the attachment. The attachment halves are held together and a mounting member on one of the two parts radially holds them together. For example, hold them together by wrapping them from the outside. The attachments on one part can be held together by the attachments on the other part. These two attachments thus simultaneously form the axis of rotation of the two parts and, on the other hand, make it possible to fix the two parts axially to each other.

This invention has the following effects. That is, the connecting member can be held radially together with the attachment of one part and fixed thereto and to the attachment of the other part. Thus, in this case it is possible to axially fix the connecting element to the two parts, and on the other hand, for example instead of being surrounded by the connecting element, one of the two attachments can also be surrounded by another element (for example an outer sleeve). .

According to a further embodiment, the connecting member can also be configured as a sleeve and placed on the pin-like attachment, slidable into the sleeve-like attachment of the other part and held together by an outer sleeve.

Further detailed features and effects of the present invention will become clear by describing preferred embodiments of the present invention with reference to the accompanying drawings.

Friend 11 Figure 1 shows a holder for a hand belt type shower. This holder is equipped with a slide 11. This slide 11 is installed on a wall member 12 so as to be replaceable. A spring 13 is provided within the slide 11. The spring 13 has a push button 14 on its lower side.
It is designed to act on

The bushing button 14 has a slope-shaped surface 15. The slide 11 has a corresponding slope-shaped surface 1
It has 6. On the side facing the wall element 12, the bushing button 14 is provided with a brake element 17. This brake member 17 is pressed and installed on the outside of the wall member 12. When actuating the bushing button 14, i.e. when moving the bushing button 14 upwards, the bushing button 14 slides somewhat to the left due to the action of the two slope-shaped surfaces 15, 16, thereby causing the brake member 17 rises from the wall member 12.

The slide 11 has a pin-like attachment 18 pointing downward. A blind hole 19 is formed in this attachment 18. A connecting member 20 is placed on the attachment 18, and a screw 21 is screwed into the blind hole 19. The connecting member 20 is generally sleeve-shaped and is supported flush with the outside of the pin 18. The connecting member 2o extends beyond the lower part 22 of the slide 11.

The connecting member 20 has a rounded groove 23 on its outer side.

This groove 23 has an annular clip.

24 is the insertion. Ifi! Element 25 is for a hand belt shower and is installed in the lower part of connecting element 20 (eg in FIG. 1). Installation member 25
has a sleeve-like attachment 26. This attachment 26 engages with the connecting member 2o and is disposed on the same surface as the outside thereof. Groove 2 placed inside it
7 is aligned with the groove 23 of the connecting member 2o. The clip 24 is thus arranged in the two grooves 23, 27 and fixes the attachment 26 to the connecting member 20.

An outer sleeve 28 is arranged on the outside of the sleeve-like attachment 26 of the installation member 25 . This sleeve 2
8 is each rib 29 formed on the outside of the attachment 26
It is locked in. In this way, the mounting member 25 is fixed to the slide 11 but can rotate together with the attachment 26 around the connecting member 20.

As can be seen from FIG. 2, both the slide 11 and the mounting member 25 are each formed from two parts and are constructed symmetrically with respect to their separating plane 3o, in a direction perpendicular to the plane of the paper. It extends to The installation member 25 is rotatable with respect to the slide 11, and its rotation axis lies in the separation plane 3o and the plane of FIG. 1, and in a direction perpendicular to the plane of FIG. It has become.

FIG. 3 is a diagram showing the hand portion 31 of the slide 11. As is clear from this figure, the separation plane 30 passes through the center of the attachment 18. Therefore, slide 11
The hand portion 31 includes the hand portion of the attachment 18. This also applies to the mounting member 25, which comprises two hand parts separated by a separation surface 30. As briefly illustrated in FIG.
It wraps around the hand part of number 8. If a second symmetrical hand portion 32 is added in FIG. 3, the hand portion of the attachment 18 will fill the inside of the connecting member 20 in FIG. Therefore, the connecting member 20 is connected to the slide 1
Hold both hand parts 31.32 of 1.

The same applies to the outer sleeve 28 associated with the mounting member 25.

As shown in FIG. 3, attachment 18 has a flat portion 33. As shown in FIG. This flat portion 33 is connected to the connecting member 20
The connecting member 20 is installed on the attachment 18 so that it does not rotate. Therefore, when the sleeve-like attachment 26 is rotated about the axis of rotation, only relative movement will occur on the outside of the connecting member 20.

FIG. 4 shows another embodiment of the invention in a simplified form. A second portion 35 is installed on the first portion 34 and is adapted to rotate with a pin-like attachment 36. This pin-like attachment 36 has a hole 37 and four elongated slots 39 in its longitudinal direction. All four slots 39 are formed from the free end 38. Due to the presence of the elongated strips 39, the pin-like attachments 36 form slightly flexible tongues 40. The tongues 4o each have a nose 41 on the outside near their ends. These nose-like members 41 engage slots in the sleeve-like connecting member 43, so that
Performs a fixing action in the axial direction and rotational direction. It is also possible to snap or lock it by inserting a pin or similar member into the blind hole 37 formed in the longitudinal direction. The connecting member 43 is provided with a rounded inward shoulder 44 approximately at the center of its inner side. The free end of the attachment 36 is located there. Below the shoulders 44 , the connecting members 43 each have a flexible tongue 45 , which connects their nose 4
At 6 it engages with a rounded groove 48 on the inside of the sleeve-like attachment 49 of the second part 35 . The sleeve-like attachment 49 is held from the outside by the pipe or outer sleeve 28 as in the embodiment of FIG.

The embodiment of FIG. 4 can be easily assembled without using screws 21.

In the embodiment of FIG. 5, the first part 34 and the second part 3
5 are each provided with a pin-like attachment 50. Both attachments 50 have the same diameter and are provided with an external radius of +1151. In the assembled state, a pipe-shaped coupling member 52 is placed across the two attachments 50.

Two rounded grooves 53 are formed inside the pipe-like coupling member 52. The width and arrangement of the groove 53 are the same as that of the groove 5.
This corresponds to 1. Their paired grooves 51.
Insert a clip (not shown) into 53. Such structures are not shown in FIG. 5 for simplicity of illustration.

In the embodiment of FIG. 6, the pin-like attachment 54
has a stepped shape, and a small diameter portion 55 with a reduced diameter is formed on the lower side. Groove 56 in small diameter portion 55
is formed.

A sleeve-like attachment 57 of the second portion 35 engages around the small diameter portion 55 and can be secured by inserting a clip (not shown) into the groove 58 . Thus, in this embodiment, attachment 57 holds both sections of attachment 54 together, thereby providing axial fixation.

On the other hand, a pipe-like member 59 is arranged beyond these two attachments and has the same outer diameter, forming a coupling member. In the illustrated embodiment, it is not necessary to axially fix the tubular member 59 to these attachments. This is because the considerable distance in the longitudinal direction of the inner end walls 60 or 61 of the two parts 34 and 35 provides sufficient fixation.

The embodiment briefly shown in FIG. 7 corresponds to the embodiment shown in FIG. 4, but differs in construction in the following respects. That is, the outer sleeve 28' is engaged around the cylindrical outer wall 62 of the second portion 35 and not around the attachment 49. For this reason, a rounded groove 64 is formed on the outside 63 of the outer wall 62,
An outer sleeve 28' is inserted therein. Therefore, fixation in the axial direction is ensured.

In the embodiment of FIG. 8, shown in simplified form, the upper portion 34 is provided with a cylindrical outer wall 70. This outer wall 70 is integrally formed and is arranged coaxially with the sleeve-shaped inner attachment 71.

A reinforcing sleeve 72 is provided within this inner attachment 71. Shoulder portion 7 of the reinforcing sleeve 72
3 is stopped at the upper part of the inner attachment 71. Sleeve 72 has two rounded ribs 74 near its outer lower end. These ribs 74 form grooves 75 therebetween. The outside of rib 74 is radially aligned with the outside of inner attachment 71 . The installation member 35 is a sleeve-like attachment 7 having a cylindrical shape.
It has 6. This attachment 76 engages in the gap between the inner attachment 71 and the outer wall 70 of said section 34. A groove 77 corresponding to the groove 75 is formed inside the attachment 76. circular clip 79
The two attachments 76 and 71 are fixed in the axial direction. Clip 79 is inserted into grooves 75 and 77.

Such an assembly is held together axially by an outer ring 78. An outer ring 78 engages around said portion 34. Therefore, the installation member is the ring 78
It is formed by.

The embodiment of FIG. 9 essentially differs from the embodiment of FIG. 8 in the following respects. That is, the groove 75 is formed directly in the somewhat thicker inner attachment 71 of said part 34 instead of a reinforcing sleeve.
